Problems solved by technology

The reliability of the SMS alarm is poor. If the mobile signal is poor, it is difficult to notify the user in time, making it useless, and even when the limit value is reached, people do not know what happens when the door is opened and the light is turned on. Dangerous phenomenon of suffocation; a gas leakage alarm monitoring device is disclosed in CN103077588A, including a gas sensor, a button, a main controller, a relay, a gas solenoid valve, a communication module, a status indication module and a power supply, and the gas sensor detects whether the gas leakage, and transmit the gas leakage information to the main controller, the main processing unit cuts off the gas supply by closing the gas solenoid valve
Although this invention can automatically control the supply of gas, it still does not have the ability to handle emergencies by itself, such as cutting off the power supply, using an explosion-proof power supply and forcibly preventing personnel from entering, which will easily cause unnecessary personnel and property losses. There is no technical solution to solve the above technical problems

Abstract

The invention discloses a combustion gas leakage alarm control system comprising a central controller, a gas leakage monitoring mechanism disposed on a combustion gas pipeline, and a detection mechanism disposed on a combustion gas appliance. The gas leakage monitoring mechanism and the detection mechanism are connected with the central controller. The central controller is provided with an emergency protection mechanism and an alarm mechanism. The combustion gas leakage alarm control system ensures combustion gas safety by multiple protections, prevents living property losses caused by manual factors, combustion gas leakage, or aged pipelines, and is simple in structure, high in intellectualized degree, and worth applying and generalizing.

Description

technical field [0001] The invention belongs to the technical field of gas monitoring and early warning devices, and in particular relates to a gas leakage alarm control system. Background technique [0002] At present, combustible gas is widely used as an energy source, which greatly facilitates people's production and life, but if it is used properly, it will benefit mankind. If there is a problem, it will easily cause a huge safety hazard. Once the gas leaks in a closed space and When it reaches the limit of explosion and encounters a fire source, it will cause accidents such as burning and explosion, causing serious economic losses and even endangering life safety. [0003] In order to use gas safely and reduce the occurrence of such accidents, it is necessary to conduct on-site real-time monitoring of gas leakage and find hidden dangers of accidents early, and take corresponding measures to avoid accidents, so as to ensure industrial safety and family life safety; with ...
