A Reactor Automatic Shutdown System

Abstract

The invention belongs to the field of reactor control and provides an automatic reactor shutdown system for a reactor. The automatic reactor shutdown system comprises a plurality of sensors for detecting whether a containment shakes or not, a plurality of sensing data processing modules, a first reactor shutdown signal generating module and a second reactor shutdown signal generating module, wherein the plurality of sensors are arranged on the containment and generate a plurality of analog acceleration signals; the plurality of sensing data processing modules generate a plurality of first logic signals according to the plurality of analog acceleration signals; the first reactor shutdown signal generating module generates a first reactor shutdown signal according to the plurality of first logic signals; the second reactor shutdown signal generating module generates a second reactor shutdown signal according to the plurality of first logic signals; the first reactor shutdown signal and / or the second reactor shutdown signal controls the reactor to shut down. The automatic reactor shutdown system for the reactor under the condition that the containment shakes, provided by the invention, still can realize an automatic reactor shutdown function of the reactor when a single reactor shutdown signal generating module has faults or a single sensing data processing module has faults.

Description

technical field [0001] The invention belongs to the field of reactor control, in particular to an automatic shutdown system of a reactor. Background technique [0002] The existing reactor control technology includes several intelligent sensor modules and a main control unit, which are connected into a data communication network by twisted pair wires. The intelligent sensor module is composed of three-axis acceleration sensor, A / D converter, single chip microcomputer, communication chip and communication interface connected in sequence; the main control unit includes the main control module and the display connected to it, sound and light alarm, keyboard, nuclear reactor emergency stop stack switch circuit, communication interface circuit. Several smart sensor modules are installed on the load-bearing structure of the buildings around the nuclear reactor equipment, and strive to obtain the largest monitoring area, and make it impossible to detect blind spots or repeated det...
