Problems solved by technology

Since many split-line detectors cannot observe the real-time status of the gas concentration on site through the host computer, and the linkage output does not separate the linkage output device (strong current) from the control unit (weak current), so design a detector that can be detected in real time through the host computer. On-site concentration information and related alarm and fault information, a combustible gas detection and alarm control system that separates the linkage output device (strong current) from the control unit (weak current) is necessary

Abstract

The invention discloses a combustible gas alarm control system comprising eight detector modules used for acquiring the concentration of combustible gas of a site in real time, a branching interface module used for receiving combustible gas concentration signals transmitted by the eight detector modules at 4-20ma and converting the combustible gas concentration signals into voltage signals, and a main controller module used for receiving the voltage signals output by the branching interface module and judging the concentration of combustible gas of the site according to data acquired in real time. The output end of the main controller module is connected with a display module, an acousto-optic alarm module and an optical coupling isolation module. The output end of the optical coupling isolation module is connected with a linkage module. The main controller module is connected with a communication module for communicating with a principal computer. The combustible gas alarm control system further comprises a main power supply module and a standby power supply module. The combustible gas alarm control system has high stability and strong anti-interference ability, and facilitates real-time observation of the complex condition of the site.

Description

technical field [0001] The invention relates to an alarm control system, in particular to a combustible gas alarm control system. Background technique [0002] With the development of society, the relationship between gases and humans is getting closer. There are many kinds of gases, among which harmful gases have seriously affected people's work and life. Important, the alarm is more and more popular because of its safety, reliability, and convenient operation. At present, the alarm system on the market can be divided into two types: split-line type and bus interface. The split-line combustible gas alarm control system is widely used in all aspects of life and industrial production, such as gas filling stations, for its stability, reliability and strong anti-interference ability. Since many split-line detectors cannot observe the real-time status of the gas concentration on site through the host computer, and the linkage output does not separate the linkage output device ...
