Nuclear power station electron card simulation and fault monitoring system and method

Abstract

The invention discloses a nuclear power station electron card simulation and fault monitoring system and method. The nuclear power station electron card simulation and fault monitoring system comprises a front machine connected with a background terminal, a test signal source, a switch power supply, an acquisition control apparatus, a card adaptation apparatus connected with an electronic card to be detected, and a humiture control cabinet, wherein the front machine is respectively connected with the test signal source, the acqusiton control apparatus and the humiture control cabinet; the card adaptation apparatus is arranged in the humiture control cabinet; and the switch power supply is connected with the card adaption apparatus for supplying power to the card adaption apparatus. According to the invention, through simulating the humiture condition of an electronic card in a real work environment or under an extreme environment condition, the function stability of the electronic card can be monitored in real time, automatic and intelligent simulation testing of the electronic card can be realized, defects of the electronic card in the real work environment or an extreme environment can be discovered timely, and circuit fault risks of a nuclear power station are effectively reduced.

Description

technical field [0001] The invention relates to an on-line monitoring technology for electronic cards in nuclear power plants, in particular to a simulation and fault monitoring system and method for electronic cards in nuclear power plants. Background technique [0002] The automation level of nuclear power plant production is high, and the realization of nuclear power plant automation and digitization depends on many control and protection systems and equipment, the core of which is nuclear power plant electronic cards. Nuclear power plants have strict requirements on the reliability and stability of systems and equipment, and correspondingly have high requirements on the functional reliability and performance stability of electronic cards in nuclear power plants. The electronic card has a wide range of applications and different environments. For example, the electric head card works in an environment with high humidity and low temperature for a long time, while the prote...

Problems solved by technology

[0003] At present, the inspection of important electronic cards in nuclear power plants still relies on manual testing, mainly for card functional testing, and the general copying test takes more than tens of hours. During this period, testers must be on site, and the workload is huge. error prone

In addition, the test conditions are often relatively simple, and it is impossible to test the functional status of the card in the real working environment or the performance stability under extreme conditions.
