Below with reference to the setting of Fig. 4 description to system 2, it is used for following the tracks of the temperature that moves and monitor group in the building at building, has physical symptom thereby can locate to be detected, for example Fa Shao people.Fig. 4 illustrates the flow chart of key step program 50.Mastery routine 50 begins with " beginning " step 52, and carries out subregion step 54, wherein access station 6 is arranged on the diverse location of building.Each access station 6 limits a unit 8, but this set is used for building is divided into recognition unit 8.The operator imports such position, wherein as the record 56 in the station location table 58 shown in Fig. 2 B each access station is set.Thereby each record 56 comprises two parts, stand ID part and position part.The station ID of access station 6 is as the position ID of unit 8.
Then mastery routine 50 enters " transmission thermometer " step 60 then, wherein each people who arrives the building entrance is provided or send thermometer 10.Be sent out thermometer 10 the people device ID, name and contact details as the record the 62 name tables 64 that are input to shown in Fig. 2 C in.Thereby each record 62 in the name table 64 comprises device ID part, name part and contact details part.Allow the people wear the thermometer 10 of transmission, make and to measure his or her temperature at least off and on by serviceability temperature meter 10.
Then mastery routine 50 enters " obtaining and the transmission temperature " step 66, and wherein thermometer 10 is measured people's temperature at least off and on and will be transmitted with its device ID corresponding to the reading of temperature.
Then when the people who wears thermometer 10 entered and enters the mouth unit 8 adjacent, mastery routine 50 entered " receiving also submission " step 68.The access station 6 that is used for unit 8 receives the transmission data of thermometer 10.As mentioned above, access station 6 is submitted to control unit 4 with its station ID of data in packet then.By this way, reading and device ID become with the ID that stands and are associated.
When control unit 4 received the packet of being submitted to by access station 6, then mastery routine 50 entered " process information " step 70.The information that utilization obtains in packet, control unit 4 can be informed in the position of people in building on the unit horizontal.
Next how to specifically describe in control unit 4 process information.When entering " process information " step 70, mastery routine 50 enters " temperature reading is low? " determining step 72, wherein whether the temperature reading in the control unit 4 specified data bags is lower than low threshold value.If determine that temperature reading is lower than low threshold value, mastery routine 50 enters " generation alert message " step 74, and wherein control unit 4 is according to generating first alert message from each table 12,58,64 information of collecting.Control unit 4 shows first alert message on the display screen of control unit 4.By the communication network of for example public paging or mobile communications network (not shown), control unit 4 can also be delivered to selected recipient, for example operator with first alert message.
Can use " temperature reading is low? " whether determining step 72 detects and thermometer 10 suitably is worn on the person.In this case, can will hang down threshold setting to for example 32 ℃ temperature, it is lower than 36.5 to 37.2 ℃ normal body temperature scope.If thermometer 10 suitably is not worn on the person and goes up or taken off from the person, then temperature reading will drop to and be lower than threshold value.For this situation, first alert message for example can be: " use warning: Mr.'s A temperature afternoon on the 2nd April in 2003 1:25 be 31.9 ℃.He is at meeting room B.", or be abbreviated as " use warning: the thermometer of normally not wearing him Mr. A of meeting room B ".In case receive such information, the operator will find Mr. A, check and guarantee that he normally puts on thermometer 10.Then mastery routine 50 enters " input record " step 76, and this will simply describe.
If " temperature reading is low? " determine in the determining step 72 that temperature reading is not less than threshold value, mastery routine 50 enters " temperature reading height? " determining step 78, wherein control unit 4 compares the temperature reading and the high threshold of thermometer 10, to determine whether temperature reading is higher than high threshold.High threshold can be set in 38 ℃.Surpass high threshold if determine temperature reading, mastery routine 50 enters " generation alert message " step 74 again.In step 74, it is adjacent with the building entrance that slave station ID identifies unit 8, and second alert message is sent to the security personnel who is positioned at inlet, and the people that thermometer 10 is worn in indication has the temperature that is higher than tolerance interval.This second alert message can be " refusal enters: Mr.'s A body temperature is 38.5 ℃ ".The security personnel can respond second alert message, escorts this people and leaves, and this people will be checked more completely by for example doctor.
If at " temperature reading height? " the temperature reading of determining thermometer 10 in the determining step 78 is equal to or less than high threshold, and control unit 4 will not send alert message to security personnel.Mastery routine 50 enters " input record " step 76 then, and wherein control unit 4 utilizes the packet that receives to generate record in temperature information table 12.Control unit 4 usefulness by it from time that packet receives time portion of new record more, so that the time is combined with the other parts that write down 14.Be that each record in the temperature information table comprises device ID, temperature reading, stand ID and temporal information.By this way, control unit 4 obtains the packet in the record.
When the security personnel in the porch do not receive set by step 72,78 determine second alert message time, then allow this people to enter and in building, walk about.Thermometer 10 will transmit temperature reading and its device ID at least off and on.For each transmission of the thermometer 10 that is received by an access station 6, mastery routine 50 is with the circulation following steps: " obtaining also to transmit " step 66, " receive also and submit to " step 68 and " process information " step 70.Continuation in time, in the temperature information table 12 of each thermometer 10, control unit 4 will generate a plurality of records.Thereby can obtain these records in the center.
The situation that enters the people of meeting room B in the building is described below.Its temperature is elevated to 38.1 ℃ when supposing that this people is in meeting room B.The access station 6 that covers meeting room B will receive the temperature reading and the device ID of this people's thermometer 10, and as mentioned above it will be submitted to control unit 4.At " temperature reading height? " in the determining step 78, the temperature that control unit 4 will detect this people is higher than high threshold.By the data from table 12,58,64 acquisitions, control unit 4 will generate the 3rd alert message then, and for example " the fever warning: at 1:25 in afternoon on the 2nd April in 2003, Mr.'s A temperature is 38.1 ℃.He is at meeting room B ".Identical with the situation of first alert message, can be presented at the 3rd alert message on the display screen and/or send to the operator.In case receive the 3rd alert message, the operator can notify security personnel or medical worker to enter meeting room B, Mr. A that accompanies and attends to the appointed area with its isolation.Can discern and locate the people of fever by this way.
After " input record " step 76, mastery routine 50 enters " contact is followed the tracks of and activated? " determining step 80, wherein control unit 4 determines whether the operator starts contact and follow the tracks of application program or feature.When thinking that the temperature reading that is received by control unit 4 has surpassed high threshold, can activate this contact tracking application program automatically.Optionally, the operator can start the feature with selected record.Be activated if determine the contact tracking characteristics in step 80, mastery routine 50 enters " carry out to get in touch and follow the tracks of " step 82 so, and wherein control unit 8 is carried out the contact tracking by the contact tracing program as shown in Figure 5 84 of back.
Below with reference to Fig. 5 contact tracing program 84 is described.Contact tracing program 84 is in the beginning of " beginning " step 86, and wherein control unit 4 is extracted in the record in the temperature information table of gathering in a period of time 12.This a period of time can be in the past 10 days.Get in touch tracing program 84 then and enter " reading and recording " step 88, wherein control unit 4 reading and recording from the record that extracts.Get in touch that then tracing program 84 enters " ID coupling? " determining step 90, wherein control unit 4 determines whether the device ID in the reading and recording equals the device ID of selected record.If the ID coupling in definite two records, would get in touch that then tracing program 84 enters " can obtain more records? " determining step 92.If in " ID coupling? " determine in the determining step 90 that the device ID of reading and recording is not equal to the device ID of selected record, get in touch that then tracing program 84 enters " ID nearby? " determining step 94, wherein control unit 4 determine to have in the reading and recording device ID thermometer 10 whether near or physics near the thermometer 10 of the device ID with selected record.In one embodiment, if reading and recording has station ID identical with selected record and the time that is roughly the same, think that then the thermometer 10 of device ID with reading and recording is near the thermometeies 10 with the device ID in the selected record.In another embodiment, if reading and recording have in the extraction record of device ID of selected record with all any one have identical station ID and the time that is roughly the same, think that then the thermometer 10 of device ID with reading and recording is near the thermometeies 10 with the device ID in the selected record.
If this " ID nearby? " determine in the determining step 94 from its thermometer 10 that obtains reading and recording not physics near thermometer 10 with the device ID the selected record, get in touch that then tracing program 84 enters " can obtain more records? " determining step 92.If determine that two thermometeies are close, then get in touch tracing program 84 and enter " record record " step 96, wherein control unit 4 is logged into reading and recording in the contact Track Table (not shown).Then, the contact tracing program 84 enters " can obtain more records? " determining step 92, wherein control unit 4 determines whether there is other record in the extraction record that will read.If define more record to be processed, then get in touch tracing program 84 and get back to " reading and recording " step 88.Otherwise, finish contact tracing program 84 in " end " step 98.
In the superincumbent system 2, thermometer 10 is described to intermittently or transmits periodically the data of being gathered by access station 6.This to the intermittence of data or transmit periodically, particularly relate to the transmission that radio frequency transmits, can consume a large amount of energy contents of battery, and use the light energy content of battery at short notice.The number of transmissions that therefore need minimize thermometer 10 is to keep the energy content of battery.
Minimize a method of the number of transmissions with reference to the flow chart description among figure 6A and the 6B, it shows mastery routine 110 and the slave program of carrying out respectively 112 in control unit 4 and thermometer 10.
When obtaining temperature reading, the slave program 112 in the thermometer 10 begins in " beginning " step 114.Slave program 112 enters " transmitting reading? " then determining step 116, wherein processor 24 is determined the transmission read instruction whether thermometer 10 receives in advance from control unit 4.If determine to receive the transmission read instruction, slave program 112 enters " transmission data " step 118 so, and wherein thermometer 10 transmits data as mentioned above.
Yet, if determine not receive the transmission read instruction, slave program 112 enters " temperature reading height? " so determining step 120, wherein processor 24 with temperature reading with transmit threshold ratio.Surpass the transmission threshold value if determine temperature reading, then slave program enters " transmission data " step 118 to transmit data as mentioned above.After " transmission data " step 118, slave program 112 finishes in " end " step 122.If determine that temperature reading is equal to or less than the transmission threshold value, then slave program 112 enters " end " step 122, and thermometer 10 does not transmit any data.By this operation sequence, 10 of thermometeies transmit data when people's heating under a cloud is promptly had a fever.Can become to be equal to or slightly less than high threshold with transmitting threshold setting.For simplicity, can threshold setting all artificial fixed values in pairs will be transmitted.For example, if high threshold is set at 38 ℃, then can become 37.5 ℃ with transmitting threshold setting.
Yet, if at " temperature reading height? " determine in the determining step 126 that temperature reading surpasses the transmission threshold value, then mastery routine 110 enters " send and transmit read instruction " step 130, wherein control unit 4 is indicated access stations 6, receive temperature reading by it and transmit read instruction with broadcasting, described instruction can be received by the thermometer in its unit 8 10.Optionally, control unit 4 can be indicated other access station 6 or all access stations 6 transmission read instructions.Then mastery routine 110 enters " end " step 128.By this way, the thermometer 10 in the unit 8 can receive and transmit read instruction and correspondingly transmit data.
The scheme that describes below shows the operation of the slave program 110,112 of advocating peace.Suppose Mr. A with Mrs X, Mrs Y and Mr. Z in meeting room B.More in the afternoon, their body temperature all is lower than the transmission threshold value that is set in 37.5 ℃.Therefore, their thermometer 10 and the access station 6 among the meeting room B do not transmit any data.1:25 in the afternoon then, the temperature that thermometer 10 detects Mr. A is 37.6 ℃, promptly is higher than 37.5 ℃ transmission threshold value.According to slave program 112, Mr.'s A thermometer 10 comprises transmission the data of temperature reading and its device ID.Access station 6 is gathered and is transmitted data and as mentioned above data and the station ID that transmits is submitted to control unit 4 together.According to mastery routine 110, the temperature that control unit 4 detects Mr. A is higher than the transmission threshold value, and will transmit reading and deliver to the one or more access stations 6 that cover meeting room B.Mrs X in meeting room B, Mrs Y and Mr.'s Z thermometer will receive and transmit read instruction, so they will begin to transmit their temperature readings separately and device ID.One or more access stations 6 will receive these and transmit data and they are submitted to control unit 4.Utilize the data of these transmission, control unit 4 can be caught data, its illustrate temperature as Mr. A be detected surpass when transmitting threshold value who near or physics near Mr. A.
If 2 of systems are used to locate people that heating under a cloud promptly has a fever or the people who does not suitably wear his or her thermometer 10, then do not need aforesaid mastery routine and slave program 110,112.In this case, thermometer after obtaining temperature reading with itself and TH1 threshold value and TH2 threshold ratio.If determine that temperature reading is higher than the TH1 threshold value or is lower than the TH2 threshold value, thermometer 10 will transmit data so, thereby give the alarm to control unit 4.Otherwise thermometer 10 will not transmit any data.The TH1 threshold value can be identical with 38 ℃ high threshold, and the TH2 threshold value can be identical with 32 ℃ low threshold value.
Can improve another aspect of system 2.This aspect relates to from the accuracy of the temperature reading of people's abdominal part acquisition.It has been generally acknowledged that, place people's Sublingual and the temperature measured in the oral cavity, provide indication accurately rationally people's central body temperature by temperature sensing end 28 with thermometer 10.Yet because the oral cavity method is to make thermometer 10 be contained in a period of time in the mouth, both inconvenience was also uncomfortable for this, so this method is not suitable for the continuous temperature monitoring.The specific part of human body, for example axillary fossa, abdominal part or waist are more convenient and comfortable for the continuous temperature monitoring.Yet, often can not provide the reading that reflects central body temperature from the measurement of these human bodies.The temperature of measuring from these positions may be starkly lower than the temperature that (for example 0.5 to 3 ℃) is measured from mouth.A common convention is with correction coefficient, and the meansigma methods that promptly obtains from the crowd is added to the measurement temperature that obtains from body part.For example, 0.5 ℃ correction coefficient can be added on 36.5 ℃ of the temperature measured from axillary fossa, thereby draw 37 ℃ temperature reading, it approaches actual central body temperature.Because changing between men, so use single shared correction coefficient can not obtain accurately determining to central body temperature at an axillary fossa and a mouthful temperature difference of measuring.Therefore just need determine temperature correction facotor for each individual.
Fig. 7 illustrates the flow chart of checking routine 132, and it is used to obtain to be used to send to the correction coefficient of people's thermometer 10.When the checking mode of activationary temperature meter 10, for example push button (not shown) on the thermometer 10 by the people, checking routine 132 begins in " beginning " step 134.Then checking routine 132 enters " measurement oral temperature " step 136, and wherein thermometer 10 prompters place his or her mouthful of Sublingual with thermometer 10, to measure oral temperature.Described prompting can be the form of emitting led (not shown).Thermometer 10 can generate the caution signals of audio or video, comes indication measurement oral temperature and prompter that thermometer 10 is placed his or her abdominal part, to measure the abdominal part temperature.The people is placed on thermometer 10 in the support 32 then, and as mentioned above support 32 is stuck on the his or her trousers.At this moment, checking routine 132 enters " measuring the abdominal part temperature " step 138, and wherein thermometer 10 is measured the abdominal part temperature.Then checking routine 132 enters " calculation correction coefficient " step 140, and wherein thermometer 10 is according to oral temperature and abdominal part temperature computation correction coefficient.Correction coefficient can be poor between oral temperature and the abdominal part temperature.Correction coefficient is stored in the thermometer 10.
Checking routine 132 finishes in " end " step 142, and wherein thermometer 10 withdraws from checking mode and rotates back into the temperature monitoring pattern.In the temperature monitoring pattern, thermometer 10 for example added by comprising that correction coefficient adjusted it before transmitting after obtaining temperature reading.In this mode, the temperature reading through adjusting of transmission approaches people's central body temperature.Initially be determined when being allowed to enter building after having no temperature in the time of can working as the people and be sent out thermometer 10 or as the people, carrying out this checking routine 132 in the porch of building.
Can improve another aspect of system 2.This relates on the other hand and is used for the high threshold whether definite people has a fever.The system 2 of last surface model has and is used for proprietary single shared high threshold.Because person to person's normal temperature difference, thereby need determine high threshold for each individual.
A method determining individual high threshold is to use the people's of up-to-date acquisition temperature reading to come the statistical computation high threshold.The temperature reading of these up-to-date measurements can be stored in the thermometer 10 or in the control unit 4.
Then the threshold value of describing the thermometer 10 of the high threshold that is used for the statistical computation people with reference to figure 8 is determined program 150.When the people pushed the button (not shown) on the thermometer 10 and wears thermometer 10, threshold value determined that program 150 begins in " beginning " step 152.Method enters " periodic measurement " step 154, wherein thermometer 10 periodically, for example per 10 seconds are once, measure and store people's temperature reading.Then program 150 enters " data collection is enough? " determining step 156, wherein thermometer 10 determines whether the quantity of temperature reading has reached predetermined quantity.Be lower than predetermined quantity if in step 156, determine the quantity of temperature reading, program 150 circulation " data collection is enough? " determining step 156 reaches predetermined quantity up to the quantity of survey measurements, for example 100 readings.When reading quantity reaches predetermined quantity, program 150 withdraws from " data collection is enough? " determining step 156 also enters " calculating high threshold " step 158.In step 158, the formula below utilizing, the processor 24 in the thermometer 10 can calculate people's high threshold:
High threshold=μ+k σ,
Wherein μ is a meansigma methods, and σ is the standard deviation of the predetermined quantity of reading, and k is a positive number.
If if the temperature reading normal distribution and the k=3 that collect, then 99.9% temperature reading will be less than the high threshold that calculates according to top formula.
Optionally, high threshold can be set for simply in the temperature reading maximum with for example 0.5 ℃ margin value and.For example, the maximum of the temperature reading of predetermined quantity is 37.5 ℃, and the gained high threshold will be 38 ℃.Also can use single temperature reading to determine high threshold.
High threshold can be input to control unit 4 by the operator, perhaps by using the data designated bag to send it to control unit 4 by access station 6.If control unit 4 receives this high threshold from thermometer 10, then control unit 4 uses this high threshold, be used in the future mastery routine 50 " temperature reading height? " comparison in the determining step 78, otherwise control unit 4 only uses the default shared high threshold that can obtain in control unit 4.Threshold value determines that program 150 finishes in " end " step 160.
Notice that the method for definite high threshold of just having described also is applicable to determines above-mentioned other threshold value, for example low threshold value, transmit threshold value, TH1 and TH2 threshold value.
Be also noted that, can carrying out the method for determining high threshold on the control unit 4 rather than on the thermometer 10.In this case, high threshold can be single shared high threshold, and it is determined according to the temperature reading that receives from all thermometeies 10, and the reading of thermometer 10 is obtained by control unit 4.
Although the present invention is described to implement in the above-described embodiments, can not be interpreted as that the present invention is limited to this.For example, system needn't comprise a plurality of access stations 6.The system that only comprises single access station 6 also can work.In this case, access station 6 can be integrated with control unit 4.That is to say that access station 6 is communicated by letter with control unit 4 by internal bus rather than by physical communication link.This system can be arranged on " checkpoint " inlet of building, office, hospital for example, the immigration control point or the intersection on airport.When being provided with like this, system is not used in the position of following the tracks of people, and only is used for " scanning " body temperature by the people of these checkpoints.People by these checkpoints is required to utilize the his or her body temperature of said temperature instrumentation amount.The reading of clinical thermometer will be sent to access station.Control unit receives temperature reading by access station again.If control unit is determined reading and is higher than predetermined high threshold, then refuse this people and enter, make and can take medical measure, this people is gone sick and with its isolation.
As another example, the system of domestic can comprise that mobile phone with Bluetooth function or PDA(Personal Digital Assistant) are as control unit.In this case, the bluetooth transponder is as access station.The bluetooth transponder is the device that only transmits the signal of its reception once more.Thermometer in this system comprises bluetooth transceiver.
As another example, thermometer can also comprise the danger button that can be triggered, so that thermometer sends the emerency request that medical treatment is noted, described requirement comprises the device ID of thermometer.Near thermometer access station receives the emerency request that sends, and it is submitted to control unit with its station ID.In case receive emerency request, control unit is display message on display screen.Information can be that " warning: Mr. A at meeting room B needs to note at once.1:25 puts down in writing this message in afternoon on the 2nd April in 2003 ".The operator can ask the medical worker to look after Mr. A immediately.
As another example, the thermometer that comprises unique device ID can be used as safe access to plant simultaneously.For example, as the people who carries thermometer during near the inlet of safety zone, can identification device ID at the access station of inlet, and corresponding permission or refusal people enter.
As another example, regional divided into unit can be included in each of several position of building emitter is set.Each emitter is suitable for sending each location identifier as sign.When each device moved to the position, device can receive the location identifier of transmission, and the time that itself and reading and operative installations obtain reading is linked together.Can when obtaining reading, reading, time and the location identifier that is associated be sent to remote location by device at every turn.Optionally, reading, time and the location identifier that is associated can be stored in the device with device identification, be uploaded to remote location after being used for.Although back one implements not allow to detect immediately, discern and locate the people with physical symptom, the data of collecting in device and storing allow to identify subsequently front and back and the approaching people of this people's physics when this people develops into physical symptom.Can also use described data identification to be detected chosen period and the approaching people of this people's physics before having physical symptom afterwards this people.Location identifier also can be the information that is recorded on the label of each position that is positioned at building.In this case, thermometer can be used to read label.If thermometer as aforesaid safe access to plant, can be sent to thermometer with location identifier so when it is used for obtaining to enter into each position.
