With in control unit (SVDU) trigger after just according to design program carry out automatically, result of the test is directly shown on SVDU.Experiment
SVDU can send out two test commands of LPTCOMMAND_1 and LPTCOMMAND_2 to each protection channel after triggering, then each
Protection channel is issued to the drive signal of third party system equipment again, and program is by comparing the feedback signal of third party system equipment
Carry out validation test success or not.Combinations different with LPTCOMMAND_2 LPTCOMMAND_1 represent different experiment moulds respectively
Formula：
Stimulus switch logic is carried out according to 00 → 01 → 10 → 11 → 00 sequence, will not theoretically trigger true letter
Number action, but since the signal switching interval time is a scan period, once the on-the-spot test actuating of relay it is relatively slow or because
For " clinging ", program is not purged confirmation to previous experiment feedback signal, this can all cause to touch in next drive test trial signal
After hair, which does not restore yet to normal mode, this will all trigger actual signal, and third party system equipment is caused to be missed
Action.

Fig. 1 is output connection signal experiment process schematic diagram outside reactor protective system.
Specific embodiment
The present invention is described further with reference to the accompanying drawings and examples.
A kind of reactor protection system external output signal test loop design method, specifically comprises the following steps：
Step 1：As shown in Figure 1, safety level is shown and control unit (SVDU) controls the first signal transmitting module

Show and confirm that 2 working condition of relay is normal after receiving experiment feedback signal with control unit (SVDU).
Step 5：Safety level is shown and control unit (SVDU) controls the first signal transmitting module LPTCOMMAND_1 and the
Binary signal sending module LPTCOMMAND_2 sends out the stimulus of " 00 " to relay, and output signal is restored to initial shape
State, relay 1, relay 2 and relay 3 are failure to actuate.
Step 6：Safety level is shown and control unit (SVDU) controls the first signal transmitting module LPTCOMMAND_1 and the
Binary signal sending module LPTCOMMAND_2 sends out the stimulus of " 11 " to relay, and trigger relay 3 acts, relay 1
It is failure to actuate with relay 2.Relay 3 is shown to safety level and control unit (SVDU) sends out experiment feedback signal, and safety level is shown

According to original design program, after triggering stimulus on SVDU, LPTCOMMAND_1 and LPTCOMMAND_2 are pressed
Stimulus is sent out according to 00 → 01 → 10 → 11 → 00 logical order so as to the circuit actuating of relay be corresponded to, so as to complete to each
The test of a actuating of relay situation.But since time interval is shorter, in the situation that first stimulus does not completely disappear also
Under, once second stimulus triggering may result in the triggering of actual signal and make so as to cause equipment malfunction.Or in relay
In the case of " clinging " occurs for device, the triggering that other any road stimulus also will all lead to actual signal is triggered.
Improvements of the present invention is to have modified the logical order that stimulus issues and increase that stimulus disappears sentences
Conclusion sentence.The short situation of signal interval is tested for each road test, logical order has been changed to 00 by us in test procedure →
01 → 00 → 10 → 00 → 11 → 00, it sends out by the automatic clear after each stimulus is sent out and then again second again and tests
Signal thus considerably increases the interval time of stimulus, eliminates and accidentally opens since stimulus interval time is short
The risk of tripartite's system equipment.The situation of " clinging " failure that may occur for busy relay simultaneously, we increase examination
The disappearance for testing signal feedback judges sentence, we pass through an experiment feedback signal on confirming before each stimulus is sent out
It has been disappeared that, be thus inherently eliminated output joint test outside totally digitilized reactor protection system and accidentally opened third party
The risk of system equipment substantially increases the reliability of totally digitilized reactor protection system.
The implementation of the present invention is explained in detail above in conjunction with embodiment, but the present invention is not limited to above-mentioned realities
Example is applied, it within the knowledge of a person skilled in the art, can also be under the premise of present inventive concept not be departed from
Various changes can be made.The prior art may be used in the content not being described in detail in description of the invention.
