Embodiment
As shown in Figure 1, be the hardware structure figure of data-storage system preferred embodiment of the present invention.This system applies connects a database server 2 through first network 4, and is connected in a plurality of measuring instruments 3 through second network 5 in Web server 1.Said a plurality of measuring instrument 3 is used to measure same testee 6.This measuring instrument 3 is meant that flowmeter, ammeter etc. measure instrument.
Wherein, Web server 1 comprise a data collection and supervisory controller (Supervisory Control And DataAcquisition, SCADA) 10, be used to gather the measured data of measuring instrument 3.In this preferred embodiment, this measuring instrument 3 is a flowmeter, and the data that said SCADA10 gathers comprise electric current, voltage etc.
Particularly, said SCADA 10 sends acquisition instructions and gives measuring instrument 3, and the data that these measuring instrument 3 feedbacks are gathered are given SCADA 10, and then, SCADA 10 sends to database server 2 with these data and preserves.In the present embodiment, this database server 2 also has many routes that SCADA 10 communicates by letter with measuring instrument 3, and has the route that SCADA 10 and measuring instrument were communicated by letter for 3 last time in the Web server 1, like route A.When SCADA 10 sent acquisition instructions to this measuring instrument 3, preferably this route A was as the communicate by letter route of SCADA 10 with this measuring instrument 3.Said Web server 1 also has a history document 12.This history document 12 is used for when first network 4 breaks down, storing all data that said SCADA 10 sends to database server 2.
As shown in Figure 2, be the functional block diagram of SCADA 10 among Fig. 1.Said module is the software program section with specific function, and this software is stored in computer-readable recording medium or other memory device, can be carried out by computer or other calculation element that comprises processor, thus the serial flow process of completion storage.Said SCADA 10 comprises: sending module 101, judge module 102, acquisition module 103, update module 104 and memory module 105.
Wherein, sending module 101 is used for sending acquisition instructions to measuring instrument 3 through the route A of said Web server 1 storage
Said sending module 101 also is used for when said second network, 5 operation irregularities, sends acquisition instructions to another measuring instrument 3 that links to each other with this Web server 1 according to the route A of storage in the Web server 1.
Said sending module 101 also is used for when Web server 1 receives 3 feedback data of measuring instrument, these data is sent in the database server 2 preserves.
Said memory module 105 also is used for when sending module 101 sends data to database server 2 failures, and these data are temporary to said history document 12.
In addition, said judge module 102 also is used for detecting at regular intervals one time first network 4, confirms whether this first network 4 can operate as normal.In this preferred embodiment, this certain hour can be 10 minutes.If this first network 4 is in proper working order, then said acquisition module 103 obtains data from history document 12, and through sending module 101 these data that get access to is sent to database server 2 and preserve.
As shown in Figure 3, be the operation process chart of date storage method preferred embodiment of the present invention.
Step S30, sending module 101 sends acquisition instructions to measuring instrument 3 according to the route A of storage in the Web server 1, and this route A is the route that SCADA 10 and measuring instrument were communicated by letter for 3 last time.
Step S31, measuring instrument 3 carries out data acquisition according to said acquisition instructions, and the data that collect are fed back to Web server 1 through route A.
Step S32, judge module 102 judge whether operate as normal of first network 4.If this first network 4 is in proper working order, then get into step S33.If these first network, 4 operation irregularities then get into step S34.
Step S33, sending module 101 are sent to 3 feedback data of said measuring instrument in the database server 2 and preserve, and process ends.
Step S34, memory module 105 is temporary in 3 feedback data of measuring instrument in the history document 12 of Web server 1, gets into step S35 then.
In step S35, whether said judge module 102 detects once this first network 4 at regular intervals also can operate as normal.In this preferred embodiment, this certain hour is meant 10 minutes.
If this first network 4 can get into operate as normal again after above-mentioned appearance is unusual, step S36 then, acquisition module 103 obtains data from said history document 12.
Step S37, sending module 104 sends in these data to the database server 2 to be preserved.
If the testing result of step S35 is a still operation irregularity of first network 4, then flow process goes to step S35, and whether continue to detect this first network 4 can also operate as normal.
In addition, present embodiment also can be realized when Web server 1 does not receive 3 feedback data of measuring instrument, reselecting the data acquisition path, and concrete work flow is as shown in Figure 4.
Step S40, judge module 102 detect whether operate as normal of said second network 5, and whether promptly judge can proper communication between Web server 1 and this measuring instrument 3.
When judge module 102 judged that second network 5 is in proper working order, step S41, acquisition module 103 obtained an other route from database server 2, like route B.
Step S42, update module 104 is changed the route A that is stored in the Web server 1 through this route B, and process ends.
Otherwise, when judge module 102 detects said second network, 5 operation irregularities, step S43, sending module 101 sends acquisition instructions to another measuring instrument 3 according to said route A, and process ends.
It should be noted last that; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although the present invention is specified with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention, and do not break away from the spirit and the scope of technical scheme of the present invention.
