Embodiment Construction

[0051] A preferred embodiment of the present invention provides a method for displaying monitoring parameters after an accident, which mainly includes the following steps: collecting monitoring parameters after an accident; isolating the collected monitoring parameters; displayed on the level device.

[0052] Further, in the display method of post-accident monitoring parameters in the preferred embodiment of the present invention, such as figure 2 shown, including the following steps:

[0053] S101. Collect post-accident monitoring parameters, that is, PAMS parameters. Due to the particularity of nuclear power plants, usually one PAMS parameter is collected by 2 to 4 measuring probes. For example, the temperature parameters of the hot end of the first loop, and the three loops are equipped with temperature measuring probes , so there are 3 acquisition signals, and the acquisition parameter signals are analog signals;

[0054] S102. Isolating and distributing the collected P...

Abstract

The invention discloses a method and system for displaying monitoring parameters after a nuclear power station accident. The method for displaying monitoring parameters after the accident mainly comprises the following steps of: collecting the monitoring parameters after the accident; isolating the collected monitoring parameters; and distributing the isolated monitoring parameters to security level and non-security level devices to display. The invention also provides the system for displaying the monitoring parameters after the accident, which comprises the security level and non-security level devices. The diversification of security level and non-security level display of the monitoring parameters after the accident is realized, and other display devices are alternative when one display device fails so as to cause no influence on normal operation; and meanwhile, the physical space is saved by using digitized computer and network technologies.

Description

technical field [0001] The invention relates to the field of digital instrument control of nuclear power plants, in particular to a display method and system for monitoring parameters after a nuclear power plant accident. Background technique [0002] According to the requirements of regulations and standards GB / T 13627 and R.G 1.97, nuclear power plants must be equipped with a post-accident monitoring system (PAMS, Post Accident Monitoring System). [0003] In traditional nuclear power plants, the analog instrument and control system is used to monitor the monitoring parameters after the accident. The implementation scheme is as follows: figure 1 As shown, wherein, the PAMS parameter is the post-accident parameter monitored by the post-accident monitoring system, which is sent to the input module 102 after the acquisition module 101, and then output to the parameter indication module 104 (conventional indicator table) through the output module 103 for display, and Output t...
