Multi-bus testing device and method for high-temperature gas cooled reactor control system

Abstract

The invention discloses a multi-bus testing device and method for a high-temperature gas cooled reactor control system. Different high-temperature gas cooled reactor digital instrument control system bus board cards are selected according to bus communication modes on different levels of a high-temperature gas cooled reactor DCS; the original bus of the digital instrument control system of the high-temperature gas cooled reactor is disconnected and then a bus board card of the digital instrument control system of the high-temperature gas cooled reactor is connected to the original communication bus; then, a corresponding high-temperature gas cooled reactor digital instrument control system test program is selected on the high-temperature gas cooled reactor digital instrument control system test program, and a working condition needing to be simulated is set on a high-temperature gas cooled reactor digital instrument control system test man-machine interface; meanwhile, a high-temperature gas cooled reactor digital instrument control system test program reads data from a high-temperature gas cooled reactor test system database, a hardware wiring is disconnected after the test is completed, and an original bus is restored to the original state. According to the invention, the problem that the DCS used by the whole process system cannot be tested due to multiple points and multiple levels of the DCS in the traditional high-temperature gas cooled reactor is solved.

Description

technical field [0001] The invention relates to the technical field of high-temperature gas-cooled reactor digital instrument control systems, in particular to a multi-bus testing device and method for a high-temperature gas-cooled reactor control system. Background technique [0002] High Temperature Gas Cooled Reactor (HTGR) is a graphite-moderated helium-cooled reactor. [0003] The digital instrument control system (Distributed Control System / DCS) of nuclear power plant is a distributed control system based on computer and network communication. DCS is an important part of a nuclear power plant, and the safety, reliability, and economy of a nuclear power unit largely depend on its performance level. With the continuous improvement of the safety performance of nuclear power plant reactors, the fourth-generation reactor DCS often has a huge number of points. The system is divided into different levels. For such a large control system, the traditional point-to-point test ...
