Device and method for confirming system testing

Abstract

The invention discloses a device and a method for confirming system testing. The device comprises a testing system and a tested system, wherein the testing system comprises a computer module, a PLC module set, a multi-path distribution module and a multi-path multiplexing module; the computer module is used for issuing a test instruction, displaying and collecting information processed by the tested system and verifying safety and normal running of the tested system with the test instruction; the PLC module comprises a central processing unit and at least two I / O modules; the central processing unit of the PLC module is connected with the computer of the testing system and the I / O module respectively; and the multi-path distribution module and the multi-path multiplexing module are connected with the PLC module and a hard wire on the tested system respectively. By using the multi-path multiplexing module and the multi-path distribution module, the number of the I / O modules in the PLC module is effectively reduced on the premise of not influencing the test effect and the cost of the testing system is reduced.

Description

technical field [0001] The invention relates to a system confirmation test device and method, a device for testing a computer control system in the field of production process automation, especially a test device used in a nuclear power plant computer control system. Background technique [0002] Computer control systems play a pivotal role in today's life and industrial production, especially since Honeywell, the largest instrument control company in the United States, first introduced its integrated distributed control system TDC-2000 (Toal Distributed Control-2000) to the world in 1975. The publication of this system quickly developed from the first generation in the 1970s to the third generation of DCS in the early 1990s. Although the technical level of the distributed system before this was already very high, after entering the 1990s, computer technology advanced by leaps and bounds, and more new technologies were applied to DCS. PLC is an electronic device developed f...

Problems solved by technology

Although this patent solves the previous motherboard function test equipment, there are many steps that require manual participation. The operator first needs the operator to place the tested motherboard on the test equipment. After the peripherals are installed, all the items tested To manually separate the selection tests one by one

Due to too many manual actions, the operator is prone to fatigue during the long-term operation process, resulting in missing some functional phenomena, so there is a quality risk, and the work efficiency is relatively low

However, this traditional device for testing computer control systems is not suitable for use in computer control systems with large scale, large capacity and high safety requirements in nuclear power plant control systems
