Embodiment 1

[0087] An embodiment of the present invention provides a monitoring system integrating safety function supervision and alarm management, including a nuclear power plant monitoring system, see figure 1 , the system consists of:

[0088] The alarm module 200 is connected to the nuclear power plant monitoring system 100, and is used to obtain electronic alarm information when the power plant is in normal operation;

[0089] The safety function supervision module 300 is connected to the nuclear power plant monitoring system 100, and is used to acquire safety function supervision information of the power plant when a safety function action is triggered under the power plant accident condition;

[0090] The first failure module 400 is connected to the nuclear power plant monitoring system 100, and is used to obtain the first failure information of the power plant when a safety function action is triggered under power plant accident conditions;

[0091] The display module 700 is res...

Embodiment 2

[0118] The embodiment of the present invention provides a monitoring method that integrates nuclear power plant safety function supervision and alarm, which is applicable to the monitoring system that integrates nuclear power plant safety function supervision and alarm shown in Embodiment 1, see Figure 5 , the method includes:

[0119] S01, acquiring electronic alarm information.

[0120] In this embodiment, the existing nuclear power plant monitoring system can be used to obtain electronic alarm information. Specifically, see Figure 5 , before step S01 also includes:

[0121] S22. In the nuclear power plant monitoring system, collect on-site parameters through the data acquisition module 101 and transmit them to the digital control system 103;

[0122] S23. The digital control system 103 judges whether the on-site parameters collected by the acquisition module 101 are normal through the preset logic in the storage module 102, thereby triggering an alarm, and transmits th...

Abstract

The present invention provides a monitoring system and method of integrating safety function supervision and alarm of a nuclear power plant. The system comprises an alarm module configured to obtain electronic alarm information; a safety function supervision module configured to obtain the information related to the safety function of the nuclear power plant; a first fault module configured to obtain the fault information at the first time of the nuclear power plant; and a display module configured to display information. The sources required by the alarm supervision at the normal operation and the safety function supervision at the event operation are collected at one screen so as to save the source of the screen; and moreover, the normal operation and the event operation use the same frame so as to prevent operators from causing human errors caused by factors such as tension, being unfamiliar with the event frame and the like.

Description

technical field [0001] The invention relates to the safety technical field of nuclear power plants, in particular to a monitoring system and method integrating safety function supervision and alarming of nuclear power plants. Background technique [0002] In the safety management of nuclear power plants, the alarm system is one of the most important systems of main control, which is very important to ensure the safe and reliable operation of nuclear power plants. However, with the introduction of digital technology, although the alarm system has more powerful processing functions, it also brings unfavorable factors such as too much alarm information to the operator, which leads to new human errors. [0003] In the existing CPR1000 nuclear power plant, under normal circumstances, the operator monitors the alarm through the alarm list; but under accident conditions, it is necessary to monitor the safety function through supporting screens such as the safety function monitoring...
