Abstract:
1. A system of testing engineered safety feature instruments, comprising: a control devices cabinet, said control devices cabinet holding a plurality of engineered safety feature instruments, said control devices cabinet comprising a communication module and a plurality of control modules; a signal terminal block, said signal terminal block being a transit terminal to relay input/output signals of hard points of said control modules; a programmable signal simulating and detecting (S/D) device, said programmable signal S/D device generating specific simulating signals and receiving specific detected signals; a simulation controlling and verifying (C/V) device, said simulation C/V device controlling said programmable signal S/D device to generate said simulating signals and receive said detected signals, said simulation C/V device verifying said detected signals, wherein said simulation C/V device directly interchanges information with said control modules to obtain detected signals from said control modules to certify whether statuses of said control modules are correct according to said simulating signals inputted into said control modules; and a communication network, said communication network being a ring network, said communication network being a media on which said control modules of engineered safety feature instruments communicate, wherein said control devices cabinet, said programmable signal S/D device and said simulation C/V device communicate through said communication network; wherein each control module is a node on said communication network; and wherein every node on said communication network interchanges information with each other through said communication network.
