Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] Such as figure 1 As shown, in an embodiment of the default value detection and setting device 2 of the nuclear power plant digital control system 1 of the present invention, it should be noted that the connection relationship between the various devices in all diagrams of the present invention is to clearly illustrate its The need for information exchange and control process should therefore be regarded as a logical connection rather than limited to physical connection. The default value detection and setting device 2 mainly includes four parts: a network signal detection module 21 , a hard...

Abstract

The invention relates to a method and a device for detecting and setting a default value of a nuclear power plant digital control system. The method comprises the following steps of: detecting a network fault signal which is received by a non-safe level digital meter control platform, and setting the corresponding default value to be 0; detecting a hard wire signal, and after determining that the hard wire signal is an ineffective signal, setting the default value corresponding to the hard wire signal; and detecting a sensor signal, and after determining that the sensor signal is the ineffective signal, setting the default value corresponding to the sensor signal. The network signal, the hard wire signal and the sensor signal are subjected to classification detection and default value setting on the basis of a safe level digital meter control platform and the non-safe level digital meter control platform of the nuclear power plant digital control system, and the default value is set by combining the nuclear safe particularity of the nuclear-power industry, so that the signal judgment and the parameter setting work of the default value are convenient and optimized.

Description

technical field [0001] The invention relates to a default value detection and setting method and device, more specifically, to a default value detection and setting method and device for a digital control system of a nuclear power plant. Background technique [0002] At present, domestic nuclear power plants have just begun to introduce a fully digital instrument control platform. Compared with the default value in the relay mode of the conventional instrument control platform, the digital control system completes the setting of the default value through software modules, adding functions of signal invalidity judgment and automatic selection . The digital control system of nuclear power plants has its particularity, and it is usually divided into two platforms: a safety-level digital instrumentation and control platform (TXP) and a non-safety-level digital instrumentation and control platform (TXP). However, the existing safety-level digital instrument control platform (TXP...
