Fuel gas intelligent early warning centralized control device, centralized control system and monitoring method

Abstract

The invention discloses a fuel gas intelligent early warning centralized control device, a centralized control system and a monitoring method. The control device comprises a controller, a monitoring mechanism, an execution mechanism, an alarming mechanism and a power supply mechanism, wherein the detection mechanism comprises a fuel gas concentration sensor and a pressure sensor, and is connectedwith the controller; the execution mechanism comprises a manual control valve, an electric control valve and a communication valve; a user connection end opening of the fuel gas supply pipeline is connected with the input of the fuel metering meter through the manual control valve; the output of the fuel metering meter is connected with the input of the communication valve through the electric control valve; the output of the controller is respectively connected with the electric control valve and the warning mechanism; the two output openings of the communication valve are respectively connected with the input of a fuel gas water heater and a gas-cooker; the power supply mechanism provides electricity for the controller, the electric control valve and the fuel gas meter. The fuel gas using safety grade of the user can be obtained through the fuzzy prediction control; the prediction and control function is realized; the accidents of the fuel gas in various aspects can be effectively prevented.

Description

technical field [0001] The invention relates to a gas protection device and a control method, in particular to a gas intelligent early warning centralized control device, a centralized control system and a monitoring method. Background technique [0002] Gas has been widely used in cities and towns, and almost every family uses gas for cooking or heating. However, in recent years, urban residents have experienced frequent poisoning and explosion accidents, especially poisoning incidents, due to improper use of gas, failure of gas stoves, gas water heaters, and problems in the civil gas pipeline network system. For example, a gas poisoning incident occurred among residents on the fifth floor of a residential area, resulting in the death of a middle-aged couple. Afterwards, it was found that due to negligence, the gas valve was not closed tightly, resulting in gas leakage. Due to factors such as improper use, long-term disrepair of pipelines, and poor quality of gas pipeline...

AI Technical Summary

Problems solved by technology

This regular inspection can effectively reduce the safety hazards caused by equipment or pipeline failures, but cannot prevent gas leakage caused by improper use or equipment failures during the inspection period

At present, some gas leakage alarms are also launched in the market. When household gas leaks, a voice prompt can be issued to remind users that the concentration of gas is too high and there is danger.

This kind of alarm device can effectively remind the household gas concentration to be too high to alarm, but this kind of gas over-standard alarm has an after-the-fact nature, and can only send out an alarm reminder without taking other protective measures
