Concrete, this device needs to carry out the construction of software architecture, for realizing nuclear power station differential pressure transmitter static press device ginsengNumber gathers and function the user-friendly use such as display, differential pressure transmitter Stress control, data analysis, information management, softPart overall construction design is sequential organization, includes the 4 big function moulds such as facility information, equipment test, test analysis, generation reportBlock and 1 database file module.And in order to realize the effective management to test equipment, use access to set up data base,Establish 5 independent lists in data base: " transmitter information ", " standard transmitter information ", " transmitter test information ", " becomeSend device inforamtion tree ", " static pressure report ", in order to store information.
Concrete test mode of the present utility model is described as follows:
After standard transmitter, test transmitter, pipeline system are carried out water flowing aerofluxus, it is arranged on test platform, confirmsAfter pipeline connects correctly, turn on the power, after the display successful connection of computer lower right corner network, double-click desktop icons enter software circleFace.
The instrumentation information such as the standard transmitter of the differential pressure transmitter of test and verification can be managed by information managementReason.User's order enters the sub-interface of information management, then selects standard transmitter information or test transmitter information to enter nextThe sub-interface of level carries out the works such as information creating, editor's (note: existing transmitter sequence number information can not be changed by editor), Copy InfoMake.
After the establishment completing facility information, after transmitter is chosen at main interface, " equipment test " can be clicked on and enter schoolTest subprogram.Clicking on " equipment test ", one dialog box of system automatic spring " please adjust and confirm that electric loading system device is returnedTo initial safe position ".This function is that motor is not returned to initial position, can carry out at this moment in order to prevent last time from having no progeny in testAdjust, prevent motor run to foremost with rearmost end and occur stuck.If electric loading system device is not in initial safe position,Can click on " retrogressing " or " advance ", program can drive motor to return to initial safe position automatically, clicks on " determination ", and entrance setsStandby test interface.
Equipment test function can realize the manual verification to test transmitter, it is also possible to realizes automatic Verification.Its interfaceContain the essential information of transmitter, high and low pressure side static pressure can be monitored in real time, simultaneously real-time by numeral and curve two waysDisplay standard scale and the force value of calibration chart, automatically calculate the absolute error of current value between standard scale and calibration chart, relatively missDifference and return difference.
High and low pressure side static pressure rises to test the work static pressure of transmitter, clicks on " 0 " in the lower left corner, can Artificial Control incite somebody to actionUnder high static pressure state, in transmitter zero test current value when balanced valve is opened and test force value input system.Click on again" automatic Verification " on interface, " the most first closes height pressure side isolating valve by pop-up dialogue box, then clicks on electric motor starting key ".
Motor is automatically switched off height pressure side isolating valve after determining after, click determines, prepares to start test." motor opens in clickDynamic " button, program can be automatically the most up more descending by point, carries out automatic Verification.
After the test of descending 25% terminates, system automatic spring dialog box " can the most first be closed electric motor starting key, and open heightLow-pressure end isolating valve ", click on automatically to move after determining and open height pressure side isolating valve, differential pressure value self-zeroing, click on the lower left corner" 0 " key, by test current value now and test force value input system.Click on " stopping " button, motor will be driven to stop.This step is to protect transmitter, it is to avoid in the case of balanced valve is not switched on, and is directly unloaded by system static pressure, causes pick-upDevice both sides differential pressure is excessive, damages transmitter.
In test process, leftmost curve can show standard curve, upper and lower limit curve of error, current test point and completeTest point, click on large buttons, then can amplify display current set point near test case.
After automatic Verification terminates, when clicking on " preservation " or " exiting ", automatic spring dialog box " can please open high and low pressure sideIsolating valve, and by system decompression ", with avoid testing terminate after forget the situation of pressure release.
After manual operation system pressure release, clicking on " determination ", automatic spring " test specification " dialog box, by test name, surveyExamination place, ambient temperature, humidity input, click on " determination ", completes to test the preservation of data.
After selecting tree diagram selects the test name under transmitter, click on " test analysis ", test result can be enteredRow playback, and standard value, test value, absolute error, relative error, return difference can be shown.Can show on curve that every is become by schoolSend the test broken line of each checkpoint of device uplink and downlink, standard curve, range of error curve etc., also curve can be amplified andReduce analysis.
Generate reporting modules and test device results can be formed the report of word version, in order to user derives report and adjustsWith, edit or printing etc..After selecting transmitter, click on " generating report ", enter report subprogram.Under report interface, can pressTest before prompting selection debugging and the test after adjustment, then the difference of twice test before and after can simultaneously showing in portion is reportedResult.
