1. the 3rd, data mode sheet format
Fig. 3 represents stored data state tableau format in above-mentioned memory 202.Its data items is included：Node IP, sensor ID, application type number, renewal time, the term of validity, data content.
Wherein node IP is the IP of communication node 103 in network, and the IP of each node has uniqueness in a network, and gateway carries out order analysis and decision-making management according to this IP.This IP can be local IP or public network IP, be specifically dependent upon the deployment scenario that this intelligent building controls network.
Sensor ID is that uniqueness of each sensor under its node distinguishes sign, and gateway preserves this information, and the unicast or multicast that line command can be entered according to different sensors is sent, so that one group of sensing data of convenient acquisition or single sensing data.
Application type number variable defined in the present invention.The present invention controls the data in network to be classified processing intelligent building：The data definition of the acquisitions such as all pernicious gas detection sensors, fire alarm cigarette propagated sensation sensor, gate inhibition's alarm sensor is alarm class data, is divided in this data mode table with 1 class data, is denoted as 01;All temperature sensors, humidity sensor, CO2Detection sensor, controlling switch etc. are obtained
Data definition be regular maintenance class data, in this data mode table with 2 class data divide, be denoted as 02.Such as technology is constantly in progress afterwards, has other class data, this classification can be revised accordingly.Define the sensor device that application type can more easily control intelligent building to control network internal, it is possible to by different category divisions different priority and processing method.It will be described in detail in flow chart of data processing of the present invention.
Renewal time indicates the temporal information that this data is sent.In intelligent building control network, having this information can easily make gateway or user know whether its data obtained meets requirement.
The term of validity indicates the period of validity of this data.Such as alarm class data, due to the key property of its real-time, the term of validity is less than certain threshold value；And for example regular maintenance class data, its real-time does not have that alarm class data are important, and network congestion will be caused by frequently updating.Therefore the data for helping terminal device network are more rationally more effectively updated by the term of validity, and the field for the important parameter that this classification considers when being also gateway decision-making has the actual data value of this data.The data of such as temperature sensor are temperature value, and and for example alarm class sensor can indicate the nothing of alert message with 0,1, have, and the rest may be inferred.
1. the 4th, user sends command format
The form that user in present implementation sends order has been illustrated in Fig. 4.Typical user command possesses：
User IP, destination address during order is beamed back for gateway；
Gateway IP, confirms whether this order is this gateway received information for gateway, or determines this order only whether certain subnet is closed in map network；
Node IP, then it is unicast order as possessed node IP in message, the node data according to correspondence IP in data mode table is carried out decision-making and send back to user by gateway, such as unreceipted node IP in message, gateway will carry out decision-making and beam back according to next bit command type；
Style number in command type, with data mode table matches, and Class1 is the acquisition of alarm class data, and type 2 is the acquisition of regular maintenance class data；
Command context, is the actual content that user sends order；
Transmission time, this information indicating user sends time during order, is used during for the gateway decision data term of validity.
Illustrate herein, a such as user command is：
[201.0.0.1][203.0.0.1][01][GET][12:36]
Can be considered IP address is that 201.0.0.1 user needs to obtain the quantity of all alarm class sensors under the gateway that IP address is 203.0.0.1, and its transmission time is 12:36.
1. the 5th, flow chart of data processing of gateway central processing unit
Fig. 5 is the typical data handling process that is prestored in the data processing module that has in the central processing unit 201 of gateway 101.
As shown in figure 5, gateway gets order at user in step 501 first.The command format can be the form shown in 1.4.After order is obtained, gateway is parsed to order, User IP is stored to memory, gateway IP and the machine IP and local routing table neutron gateway IP are contrasted, next step parsing is carried out if destination address is the machine IP, if destination address is that forward command to correspondence subnet is closed if subnet closes IP.Hereafter, the parsing to command type and subcommand time is carried out, and next step is carried out by this command type.
Step 502 is data mode table query steps, and in step 501, gateway has extracted command type.In this step, gateway extracts all same type data according to such model in data mode table, the application type in this command type corresponding table.As do not possessed this type data in table, then directly no data information is returned to user.As possessed such data in table, then into data judgment step 503.
Step 503 is data judgment step, and its deterministic process according to step 601-604 as shown in fig. 6, implement.The purpose of this judgment step is whether the data examined in Check data mode tables meet requirement, and such as meet requirement directly can beam back to user, as being unsatisfactory for requiring, be returned to the new data of the sensor requirements of node administration.The purpose of this step is to reduce gateway transmitting order to lower levels quantity, mitigates the jam situation of end side network, and further reduces the user terminal stand-by period.To each data extracted in step 502, the calculating data survival phase T of step 601 will be enteredeStep.Data survival phase TeCalculation formula it is as follows：
Te=(subcommand time）（Data time）
The time that subcommand time is said the word by user herein, and data time is then the renewal time of the data in data mode table.Survival period TeThis data is illustrated from the period being issued to when user requires.
Hereafter judgment step 602 is carried out, gateway will determine that whether the data survival phase is less than the term of validity.The meaning of this logical relation is, shows that the time-to-live of this data is less than period of validity threshold value if survival period is less than the term of validity, is effective；Show that this data survival period is longer if survival period is more than the term of validity, it is as invalid more than term of validity threshold value.Data return to step 504 can be directly entered to valid data；Next step data is also carried out to invalid data and updates step.
Node IP of the step 603 then for gateway data accordingly sends data retrieval commands, and updates the data state table after the receipt, enters next step data return to step 504 using the data after renewal.
In data return to step 504, data configuration returned data bag of the gateway in the User IP and data state table prestored, and this packet is sent back to user.
1. the 6th, gateway returns to the form of user
After mentioned order and flow chart of data processing, gateway returns data into user.Fig. 7 represents to return to an example of the data format of user.
As shown in fig. 7, this packet possesses：
The gateway IP of sent out data, shows source address；
User IP, shows destination address；
Data content, is loaded as the data needed for user；
Transmission time, this time can indicate the temporal information of this data.
Illustrate herein, such as the order that a user command is form as shown in 1.4, it, which obtains data, to be：
[203.0.0.1][ 201.0.0.1][0][12:38]
It can be considered that all alarm class sensors are without warning information under the data sign gateway 203.0.0.1 that the user that IP address is 201.0.0.1 to IP address by 203.0.0.1 gateway returns, its transmission time is 12:38.
1. the 7th, effect

2nd, embodiment 2
Illustrate embodiments of the present invention 2 below in conjunction with Fig. 8.Present embodiment 2 is that the embodiment to the further integrated treatment of returned data has been added on the basis of embodiment 1.
First, the general idea of present embodiment 2 is briefly described.SP, it is contemplated that in intelligent building control network, the ordered multicast demand of user, gateway needs to reply unicast and ordered multicast respectively.For unicast data, gateway can be directly by data recovery to user；And for ordered multicast, many datas of reply to user are not optimum way.Further optimize this communication process, reduce network congestion.For this demand, the present invention provides embodiment 2.
In present embodiment 2, the structure chart of gateway and required data mode table and main handling process shown in Fig. 5 are consistent with embodiment 1, will not be described here.Hereinafter, the flow and data processing method of the data return to step 504 in present embodiment 2 are described in detail.
2. the 1st, multicast and aggregation of data value
In intelligent building control network, user, which often may require that, uses ordered multicast.For example user need to obtain the real time temperature of this floor, and the temperature sensor that and for example first floor has is about dozens of or so.If gateway only supports unicast order, user is only capable of obtaining every time the temperature of each sensor, finally observes mean temperature, this process is very cumbersome.Such as support ordered multicast, user can be according to the gateway IP of this floor, and this order can be obtained by sending all nodes for possessing temperature sensor in an ordered multicast, floor, and
Return to the real time temperature of each sensor.The order number now sent by user is largely reduced, and the communication process from user to gateway will optimize significantly.Further, the node temperature mean value computation process of all temperature sensors can be completed by gateway, and a reply data are also only sent from gateway to user.The data volume for now returning to user by gateway also can be reduced largely, and now user is to the data interaction between gateway up to optimal.
The form that user is said the word if it possesses node IP as shown in figure 4, show that the data of sensor in specific a certain node need to be obtained.Such as it does not possess node IP, only possesses gateway IP and then shows that the aggregation of data value of certain all application type under the gateway need to be obtained.The optimization purpose of this aggregation of data value is a plurality of data-optimized to one, and the calculating process of this aggregation of data value is completed by gateway.
2. the 2nd, flow of data return to step
As shown in figure 8, being performed in gateway in flow chart of data processing after the end of data judgment step 503, into data return to step 504.Now gateway can carry out integrated treatment according to different application types to different data.
Step 801 judges that the data type is alarm class data or regular maintenance class data to parse in the application type step of data, this step.
Step 802 redirects judgement for different application type, and step 803-804 processes are entered if for alarm class data, alarm class sensor is traveled through, and calculates the quantity for wherein triggering alarm, most sum is sent to user at last；Enter step 805-807 processes if for regular maintenance class data, be that the data of different sensors classification carry out mean value calculation to different sensors ID, most integrated information sends back user at last.
2. the 3rd, effect
According to the embodiment of the present invention 2, it can reduce and information content between gateway and user is reduced on the basis of gateway transmitting order to lower levels quantity, further mitigate the load of gateway and the jam situation of whole network, and further increase the convenience that user uses.

4th, embodiment
Hereinafter, three embodiments of the present invention are illustrated with reference to Fig. 1 Figure 13.
4. the 1st, embodiment 1
The present embodiment is based on above-mentioned embodiment 1.
First, in the initialization procedure of network, gateway 101, subnet close the sensor 104 of 102, node 103 including its management and are unlocked.Subnet is independently found with posterior nodal point 103 and closes 102 or gateway 101, access network is asked.Subnet, which closes 102, also independently finds or has been connected to gateway 101.So as to form end side network.The network can be managed by gateway via local user 105 or long-distance user 106.
In the network, user 105 and user 106 herein can be single or multiple, depending on network management or user the need for disposed.In the larger network of number of devices, subnet, which closes 102, can shunt the data of gateway 101, play reduction network congestion, support the effect of more equipment, and quantity can be disposed as the case may be, support multiple subnets to close 102;In the less network of number of devices, subnet can not also be used to close 102, the framework being directly connected using gateway 101 with node 103.Subnet closes the topological structure such as network support typical case of the prior art is star-like or tree-like between 102 and gateway 101, in the present invention
In without being discussed in detail.Communication node 103 is the communications device terminal with IP, and it connects one or more sensors 104 containing ID, and connected mode can be that serial ports or bus are connected.The sensor 104 that each communication node 103 is managed can be that different type can also be same type, and complex different types of sensor is considered in the present embodiment.The distribution of sensor 104 depends on convenient during building network is disposed and the factor such as is easily managed.
After initialization, the data for the sensor device that all nodes 103 are managed it are obtained first in network, and are sent to gateway 101, and gateway 101 constructs data mode table according to these data, as shown in Figure 3.Correspondence possesses node IP, sensor ID, style number, the renewal time of data, the term of validity of data and data in itself per data.For style number, according to sensor ID, its application type is defined by gateway 101.The present invention controls the data in network to be classified processing intelligent building herein：The data definition of the acquisitions such as all pernicious gas detection sensors, fire alarm cigarette propagated sensation sensor, gate inhibition's alarm sensor is alarm class data, is divided in this data mode table with 1 class data, is denoted as 01;All temperature sensors, humidity sensor, co2The data definition of the acquisitions such as detection sensor, controlling switch is regular maintenance class data, is divided in this data mode table with 2 class data, is denoted as 02.Such as technology is constantly in progress afterwards, has other class data, this classification can be revised accordingly.Renewal time indicates the temporal information that this data is sent.In intelligent building control network, having this information can easily make gateway or user know whether its data obtained meets requirement.The term of validity indicates the period of validity of this data.Such as alarm class data, due to the key property of its real-time, the term of validity is less than certain threshold value；And for example regular maintenance class data, its real-time does not have that alarm class data are important, and network congestion will be caused by frequently updating.Therefore the data for helping terminal device network are more rationally more effectively updated by the term of validity, one of important parameter that this classification considers when being also gateway decision-making.Field has the actual data value of this data.The data of such as temperature sensor are temperature value, and and for example alarm class sensor can indicate the nothing of alert message with 0,1, have, and the rest may be inferred.
After data mode heading time is set up, it is updated according to the mode such as the timing transmission of node or user command active obtaining data, so as to ensure the real-time of data.
Then, by taking user b as an example, it is assumed that now user b is it should be understood that such as security protection situation in the building, that is, need to obtain the comprehensive condition of the alarm class sensor in the network, how many sirens are in information as alarm state.
Now user first sends the data retrieval commands to gateway 101.Setting due to intra-gateway memory to corresponding application type is preserved, therefore can support the command type shown in Fig. 4.IP such as user is 201.0.0.1, and the IP of purpose gateway is 203.0.0.1,36 points when the time that sends is 12.Now user can carry out data retrieval commands transmission according to corresponding browser or web-based management instrument, and its sending method can be realized by relevant art of the prior art, be not discussed in detail herein.Had in the order
Standby necessary factor may make up the typical format of this order, as shown in Figure 10.
Gateway 101 is handled accordingly after the order shown in Figure 10 is received by 201 pairs of orders of central processing unit, and its process step is as shown in Figure 5.Step 501 represents that central processing unit 201 gets order from user side interface 203 first.In this step, central processing unit 201 is also parsed to order, and User IP 201.0.0.1 is stored to memory 202, and gateway IP 203.0.0.1 and the machine IP and subnet are closed into IP lists is contrasted.Command type deposit memory is further extracted if gateway IP is the machine IP, step 502 is carried out;Such as the IP that gateway IP is some subnet pass, then pass through the forward command of interface 204；Such as gateway IP is mismatched with these, then abandons order, and return to error message.In this embodiment, gateway IP and the machine IP-cause, central processing unit 201 extract the deposit memory of command type 01, and enter next step 502.
The step 502 then carried out is that data mode table Check askes step.Central processing unit 201 extracts all same type data, according to command type for the style number in table according to the command type 01 stored in previous step in the data mode table that memory 202 is stored first.In data mode table as shown in Figure 3, the data being extracted are as shown in figure 11.In this embodiment, meeting the data of same type has 3, will enter next step data judgment step 503.If not having to meet desired data in this step, i.e., do not possess this type data in table, then beam back error message, and terminator to user.
Data judgment step 503 is one of committed step of the present invention, and its deterministic process is as shown in Figure 6.The purpose of this judgment step is that whether data meet requirement in the data mode table being extracted for examine Check Figure 11, and such as meet requirement directly can beam back to user, as being unsatisfactory for requiring, be returned to the new data of the sensor requirements of node administration.The purpose of this step is to reduce gateway transmitting order to lower levels quantity, mitigates the jam situation of end side network, and further reduces the user terminal stand-by period.To each data extracted in step 502, the calculating data survival phase T of step 601 will be enteredeStep.Data survival phase TeCalculation formula it is as follows：
Te=(subcommand time）（Data time）
The time that subcommand time is said the word by user herein, and data time is then the renewal time of the data in data mode table.Survival period TeThis data is illustrated from the period being issued to when user requires.
To three datas included by Figure 11, correspondence subcommand time 12:36 its TeResult of calculation it is as follows：
10.0.0.1 01 Te=4
10.0.0.2 01 Te=l
10.0.0.18 01 Te=l
Hereafter judgment step 602 is carried out, central processing unit 201 judges whether the data survival phase is less than the term of validity.The meaning of this logical relation is, this data is shown if survival period is less than or equal to the term of validity
Time-to-live is less than period of validity threshold value, is effective；Show that this data survival period is longer if survival period is more than the term of validity, it is as invalid more than term of validity threshold value.Data return to step 504 can be directly entered to valid data;Next step data is also carried out to invalid data and updates step.Therefore in Figure 11 3 datas determine whether it is as follows：
10.0.0.1 01 TeThe term of validity is 3, T in=4e>3, into step 603;
10.0.0.2 01 TeThe term of validity is 3, T in=le<3, into step 504;
10.0.0.18 01 TeThe term of validity is 3, T in=le<3, into step 504.
In step 603, central processing unit construction order, send to IP be 10.0.0.1 node, its command format can using in Figure 12 form as example.In later step 604, central processing unit updates the data corresponding position in state table according to the node 10.0.0.1 data returned, in this embodiment, and Fig. 3 and Figure 11 corresponding data are intended to update.The data is made to enter next step 504.
The tables of data now extracted is as shown in figure 13.
In data return to step 504, central processing unit is by according to the User IP deposited:201.0.0.1 with the data configuration returned data bag in data mode table in Figure 13, and this packet is sent back to user.It beams back the example reference picture 7 of data format.As shown in figure 14, comprising gateway IP:203.0.0.1, User IP:201.0.0.1, data： 10.0.0.1/1; 10.0.0.2/0;10.0.0.18/1, send the time 12:37.
User is obtained after this data, can be known in this network i.e. this building, whether each alarm sensor is triggered.When number of sensors is larger, user, which only sends a subcommand, can obtain comprehensive information, and transfer to gateway to judge to obtain or send the data stored, greatly improve convenience and efficiency that user uses.Before the deadline, user can obtain the data of network inner sensor at once to such as all data, and further forwarded without waiting for gateway, obtain sensing data.
As can be seen that using the data mode table and corresponding data query and judgment step of the present invention by taking this embodiment as an example, it is possible to reduce the number of times of the forward command of gateway 101, the jam situation of end side network is alleviated.
4. the 2nd, embodiment 2
The present embodiment is based on above-mentioned embodiment 2.
First, the general idea of present embodiment 2 is briefly described.SP, it is contemplated that in intelligent building control network, the ordered multicast demand of user, gateway needs to reply unicast and ordered multicast respectively.For unicast data, gateway can be directly by data recovery to user；And for ordered multicast, many datas of reply to user are not optimum way.By taking embodiment 1 as an example, it can be seen that last gateway is returned in the information of user, and included information content is very big, in some communication protocols or environment by prescribing a time limit, generally require to carry out subpackage transmission.Therefore, further optimize this communication process, the data of returned data are optimized, reduce network congestion.For this demand, the present invention provides embodiment 2, and proposes embodiment 2 with this.
In the present embodiment 2, the main flow shown in hardware configuration and required data mode table and Fig. 5 needed for gateway 101 is consistent with embodiment 1, and description is not repeated herein.Following part illustrates the flow and data processing method of the data return to step 504 related generally in the present embodiment 2.
After the completion of the data judgment step 503 shown in Fig. 5, gateway obtains the tables of data that user is required and satisfies the prescriptive period, as shown in figure 13.Flow chart of the present embodiment according to Fig. 8 is handled these data.Now central processing unit 201 can carry out integrated treatment according to different application type to different data, and citing in the present embodiment proposes the process step to alarm class data.
First bar enters data return to step 504 by the node 10.0.0.1 data produced.As shown in figure 8, step 801 is parsed to the application type of data.In this step, data class model 01 is extracted.
The alarm types judgment step then carried out, this data class model 01 is contrasted with the alarm class data class model prestored, is also 01 herein.Therefore alarm class data are met, into step 803.
The defined variable X before step 803 initialization, and its value is set to 0.When each meets alarm class data by this step, the specific data of the data are further detected, such data is 1, and the alarm for representing the sensor has been triggered, and now variable X adds 1.
Identical processing procedure is carried out to the second data.The application type of data is parsed in step 801.In this step, data class model 01 is extracted.
The alarm types judgment step then carried out, this data class model 01 is contrasted with the alarm class data class model prestored, is also 01 herein.Therefore alarm class data are met, into step 803.
Judged in step 803, data are 0, the alarm for representing the sensor is not triggered, now the value of variable X does not make any changes.
Identical processing procedure is carried out to Article 3 data.Step 801 is parsed to the application type of data.In this step, data class model 01 is extracted.
The alarm types judgment step then carried out, this data class model 01 is contrasted with the alarm class data class model prestored, is also 01 herein.Therefore alarm class data are met, into step 803.
When step 803 judges, data are 1, and the alarm for representing the sensor has been triggered, and now the value of variable X adds 1.
Same repeat step 801 to 803,3 datas in fig. 13 are completed after judgement, and variable X numerical value is 2.In step 804, the numerical value is sent back to user.
Equally, central processing unit is according to the User IP deposited:201.0.0.1 the data configuration returned data bag stored with variable X, and this packet is sent back to user.It beams back the example reference picture 7 of data format.As shown in figure 15, comprising gateway IP:203.0.0.1, User IP:201.0.0.1, data：2, send the time 12:37.
User is obtained after this data, can be understood and be obtained this network i.e. this building interior, there is 2 alarm biographies
Sensor has been triggered, and can quickly obtain alert in building, and can make accurate judgment and handle on this basis.
It can be seen that by taking this embodiment 2 as an example, using the data mode table and corresponding data query and judgment step of the present invention, and processing method, further optimization communication process is realized, the data volume of returned data, which has, to be significantly reduced, and thus network congestion significantly mitigates.
4. the 3rd, embodiment 3
The present embodiment is based on above-mentioned embodiment 3.
Because embodiment 3 has added the embodiment of gateway data handling process when node actively sends data.This embodiment will be described in detail for the present embodiment.
First, the general idea of embodiment 3 is briefly described.SP, it is contemplated that in intelligent building control network, the real-time demand of data with alert.For regular maintenance class data, its time claimed range is wider, can periodically be initiated to update by gateway, be stored in data mode table, user is back to via the acquisition order of user；And it is very high for the required ageing requirement of this significant data of alarm class, such as wait user to obtain the adverse consequences that will cause to handle not in time.
In intelligent building control network, the data definition of the acquisition such as pernicious gas detection sensor, fire alarm cigarette propagated sensation sensor, gate inhibition's alarm sensor is alarm class data.The characteristics of such sensor is real-time monitoring, when running into more than threshold value, will be triggered, and produces data.Using formula is actively sent more than the data of sensors with auxiliary electrode, alarm is sent after triggering to gateway.It is very high for the required ageing requirement of alarm class significant data, failing to transferring to user's processing then to cause adverse consequences in time.
Therefore gateway has suitable processing method to such data, to ensure that alarm class data can inform user in real time, is easy to user to know alert.On this basis, user at least preserves 1 management end IP to gateway, and this IP can be sent data to by being easy to gateway to get such data.In the present embodiment, management end IP is set to 100.0.0.1.
Furthermore, it is contemplated that the situation that single sensor may break down, user may be reaffirmed or be arranged Check to the data of alarm class sensor.On the other hand, to warning information such as fire alarm cigarette propagated sensation sensors, user obtains the coverage situation of such alert again, is easy to preferably processing and investigates.Therefore this kind of emergency data is quickly updated by gateway, is easy to the secondary acquisition data of user.In present embodiment, gateway is received after alarm class data, after transmission notebook data to user, parses sensor ID, the data to sensors with auxiliary electrode in network are updated, to obtain latest data situation.
The initialization procedure of gateway 101 and other network equipments can be with using identical step in embodiment 1.After initialization, such as IP, for 10 Shang 1.23 node, its lower fire perceiving device 02 is triggered, and produces a data, as follows：
IP: 10.1.1.23 ID:02 time： 13:48 data： 1
Node sends this data to gateway, and now node active data handling process of the gateway 101 according to Fig. 9 is handled.As shown in Figure 9：
The data step 901 is receives data step, at this moment due to receiving the data of node, and this flow is triggered beginning；
Step 902 is to update the data state table step, the existing data after receiving the data in the corresponding data mode table of the information updatings such as the node IP of data, sensor ID of gateway 101, data bit 1 that will be new is written to corresponding data bit, will safeguard into this data transmission time 13 renewal time:48;Then into next step, the data mode table after renewal is as shown in figure 16；
In step 903, gateway 101 is extracted after updating the data to application type, and is judged：It is such as regular maintenance class data, then directly terminates, next step 904 is entered if for alarm class data.In this embodiment, application type is 01, as alarm class data, is directly entered next step 904;
Such as step 904 sends this alarm class data to the alert management IP 100.0.0.1 that prestore to send gateway in data step, this step, and its transmission form refers to the transmission message format in embodiment 1,2, shown in Figure 17.The user of test side receives real-time alert, and is thus further processed；Step 905 after warning information is sent, it is contemplated that the secondary acquisition possibility of user and the requirement of real-time of alarm class data, extracts the sensor ID 02 of this data to extract sensor ID step；Following step 906 is then according to the sensor ID 02 extracted in step 905, and the node for possessing sensor ID 02 into end side network sends data retrieval commands, waits newest associated alarm class data to be received；
Step 907 is that reception updates the data step, after the latest data that node is beamed back is received, state table is updated the data successively, and wait next step command of user.Its example is as shown in figure 18.
Compare Figure 16 and Figure 18 as can be seen that the node that IP is 10.1.1.2 has the sensor that same ID is 02.Before sensor 10.L1.23 data are sent, the sensor is probably due to failure or because causing its sensing data to fail real-time update the problems such as packet loss during data transfer, after step 906 and step 907, node 10.1.1.2 gets new alert message after updating the data, contribute to user to obtain the real-time good overall view of alert, be easy to next step to handle.
In the case of the present embodiment 3, important, urgent alarm class data are received in gateway（Such as the alarm of fire data in intelligent building control）When, this data quickly can be reported into user, it is ensured that the timely transmission of significant data and emergency data, and comprehensive data with alert is further obtained, provide good basis for the real-time processing of user.
