Nuclear reactor earthquake protection warning system and monitoring control method

Abstract

The invention relates to a nuclear reactor earthquake protection warning system and a monitoring control method. The system comprises intelligent sensor modules and a main control unit, and is connected into a data communication network by a twisted pair. The intelligent sensor modules comprise triaxial acceleration sensors which are connected in sequence, an A / D (analog / digital) converter, a single-chip processor, a communication chip and a communication interface. The main control unit comprises a main control module and a display, audible-visual annunciator, a keyboard, a nuclear reactor emergency shut down switch circuit and a communication interface circuit connected with the main control module. The installation and control method of the system comprises the following steps of: (A) embedding a plurality of intelligent sensor modules according to the theory of distributed network topology and the principle of making every effort to obtain the maximum monitoring area; (B) inputting control parameters into a main control module of the nuclear reactor earthquake protection warning system; (C) comparing signals collected by the intelligent sensor modules with the control parameters in the main control unit; and (D) judging whether to automatically stop the working of a nuclear reactor in earthquakes and strong shocks, instruct working personnel to escape, and the like.

Description

technical field [0001] The invention relates to an earthquake protection and alarm system of a nuclear reactor and a monitoring and control method thereof, in particular to an earthquake protection and alarm system capable of quickly shutting down a nuclear reactor when an earthquake occurs and a monitoring and control method of the system. Background technique [0002] When nuclear reactors are in normal operation, they generate huge energy and bring huge wealth to mankind. But if a nuclear reactor operates in an abnormal state, it may produce a huge disaster. For example, if an earthquake occurs during the operation of a nuclear reactor, if the strong earthquake lasts for a long time, the integrity of the system will be easily damaged, and the control rods will not be able to fall into the pipeline smoothly, which may cause the fuel elements of the nuclear reactor to burn out, radioactive spillage, pollute the environment, and cause casualties. When a strong earthquake ca...

Problems solved by technology

[0003] The purpose of the present invention is to provide an earthquake protection alarm for nuclear reactors in order to overcome the disadvantages that the existing nuclear reactor emergency shutdown method uses manual shutdown by on-duty personnel, and cannot be operated due to force majeure during strong earthquakes, or the operator has a long reaction time and is prone to mistakes. system, the earthquake protection and alarm system can not only quickly and automatically shut down the nuclear reactor when a strong earthquake occurs, but also send an earthquake alarm to the staff to guide the staff to quickly evacuate the room and escape to a safe area
