Embodiment 1

[0015] Example 1: XSB64 board simulation test

[0016] Board function description: Daya Bay simulator interface board switch output,

[0017] 1. Test overview:

[0018] a) Insert the XSB64 board into the slot of the simulation platform of the simulator, select the type of test board, start to set the parameters and test, the XSB64 board receives 16-bit binary words through the bidirectional data bus and sends the selected data to the external interface, that is 16-bit data is given from B0-B15, and 4 words are output through different working states of WORD0, WORD1, WORD2, WORD3 of 8 CD4723 address latches (double 1 select 4 selection), and the signal logic is combined by 74C85 and 74LS10 For time-sharing control, the input signal is distributed through the resistance-capacitance network, and then the 64-bit data is reversely output through the 2N6660 OC gate (drive transistor), that is, various switching output signals on the analog console are executed.

[0019] b) Address...

Description

technical field [0001] The invention relates to testing technology, in particular to an off-line testing system and method for nuclear power plant unit interface equipment. Background technique [0002] There are many interface devices in the nuclear power plant unit. The performance of these interface devices directly affects the operational reliability and safety of the unit. Therefore, how to detect the performance of these interface devices and prevent accidents has become a must for each nuclear power plant. solved problem. At present, the detection of these interface devices is generally carried out after the interface devices are removed on site. This detection method not only affects the normal operation of the unit, but also because the removed interface devices are difficult to reflect the real status Performance, it is difficult to detect individual indicators to meet the needs of ensuring the security of interface devices. In addition, for nuclear power plant o...
