Bus type gas monitoring and alarming control system and method

Abstract

The invention relates to a bus type gas monitoring and alarming control system. The bus type gas monitoring and alarming control system comprises a controller main machine and a plurality of gas detectors, the gas detectors are in communication with the controller main machine through buses, the gas detectors are connected in parallel, the buses are half-duplex communication buses, and the buses are three-wire system buses or four-wire system buses. The invention further relates to a method for achieving bus type gas monitoring and alarming control on the basis of the system. According to the bus type gas monitoring and alarming control system of the structure and the method, the gas monitoring and alarming control system can be achieved through a simple bus communication algorithm, and the reliable and perfect gas monitoring and alarming control system is set up at the lowest cost, and through a precise algorithm and effective circuit design, the whole system is reliable and high in compatibility, solves the problems that an existing system in the market is high in cost and poor in reliability and compatibility, and has a wider application range.

Description

technical field [0001] The invention relates to the field of safety instruments, in particular to the field of gas monitoring and alarming, in particular to a bus-type gas monitoring and alarming control system and method. Background technique [0002] Gas alarm controllers in the prior art are often unable to achieve compatible connections with three-wire and four-wire gas detectors. Point-to-point connections are often used between the controller host and gas detectors, and one-to-one connections are also used for bus connections. The method is single, has low reliability, and increases the cost of the system at the same time, which is not conducive to large-scale popularization and application. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and to provide a gas monitoring and alarm control system that can realize gas monitoring and alarm control with a simple bus communication alg...
