Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is done further detailed description:
A kind of method for testing and analyzing of event sequence recording system, as shown in Figure 1, may further comprise the steps:
Step 1: SOE system, SOE signal generator and SOE test analysis terminal linked together makes up the test analysis platform.
As shown in Figure 2, the SOE system is connected and composed through EPA by the historical station of SOE system for field control station and SOE system, and this SOE system for field control station comprises polylith SOE system signal acquisition module; SOE signal generator trigger switch amount signal is used to simulate the SOE signal; The SOE signal generator can trigger out interval time can regulate and be not less than 32 switching value signal between 0.1ms～3ms; Accuracy can reach 0.1ms～0.3ms, can be manually or change each channel signal trigger sequence automatically; SOE test analysis terminal is a computing machine that test analysis software is installed, and this test analysis software has functions such as test parameter setting, data importing derivation, data analysis contrast.A plurality of output channels of SOE signal generator are connected through the input end of many barss cable with polylith SOE system signal acquisition module respectively, and the output terminal at the historical station of SOE system is connected with SOE test analysis terminal.
When the SOE signal generator is connected with SOE signal acquisition module to be tested; For preventing that misconnection, virtual connection take place when disassembling or recover on the SOE signal acquisition module terminal original line, missing or the like problem; Guarantee after SOE test is accomplished its system errorless bringing normally into operation that can do as usual, should take following two kinds of methods of attachment:
(1) if the terminal of SOE signal acquisition module to be tested is detachable; Then earlier each passage of SOE signal generator signal cable is connected to respectively on subsequent use dead end of SOE signal acquisition module; Terminal with all SOE signal acquisition module to be measured disassembles again, the spare terminal that has connected in the replacement;
(2) if the terminal of SOE signal acquisition module to be tested is on-dismountable; Then should pull down every connecting line in proper order; And pull down that a pair of connecting line twines and put on channel number and the terminal number of institute's respective modules immediately with insulating tape so that identification when recovering, the line of having torn open behind all connecting lines again each passage of SOE signal generator signal cable connects the SOE signal acquisition module.
Step 2: detect whether satisfy test condition, trigger interval, the trigger sequence parameter of SOE signal generator is set.
In order to guarantee that test analysis normally moves, should satisfy following test condition:
1, the production technology system is in normal shut down condition or SOE signal correction protection and has excised state;
2, the SOE system is in normal operating conditions and its warning, historical query, the printing function input is normal.
After satisfying test condition, the setup test such as trigger interval, trigger sequence parameter of SOE signal generator is set.
Step 3: begin to carry out SOE test, the intact signal of every triggering is a test, is no less than recording test time 20 times for the test pass of each SOE signal acquisition module.
Step 4: the test parameter that this test is set on SOE test analysis terminal.
Step 5: SOE RP configuration file is directed on the SOE test analysis terminal, simultaneously the SOE historical data in the test duration section is directed on the SOE test analysis terminal.
Step 6:SOE test analysis terminal compares analysis, draws test result.
Step 7:, then reduce the trigger interval of SOE signal generator or change trigger sequence, repeating step 3 if test result is correct; If test result is incorrect, then stop test.
Step 8: draw test result according to test result, form test report.
The present invention for the accuracy that guarantees to test, has made following test request when carrying out test analysis:
1, need just to draw conclusion more accurately through a large amount of tests, signal generator is according to trigger interval time behind each passage as 1 time test successively, and whole test process needs the test through being no less than 20 times for each SOE signal acquisition module to be tested;
2, anti-the trembling the time of every signal that must not be lower than tested SOE signal acquisition module interval time all over test is generally more than the 4ms;
3, because the historical data transmission buffer capacity limit of different SOE system is different; For preventing that the recorded information amount from exceeding its buffer memory restriction and causing data to overflow or write down the phenomenon generation of confusion; It is long to continue the test duration, and takes promptly pause for 5 times time interval more than 5 minutes of follow-on test to continue the method for testing again;
4, through being carried out analysis-by-synthesis, every time result draws final conclusion.
It is emphasized that; Embodiment of the present invention is illustrative; Rather than it is determinate; Therefore the present invention is not limited to the embodiment described in the embodiment, and every other embodiments that drawn by those skilled in the art's technical scheme according to the present invention belong to the scope that the present invention protects equally.
