Intelligent gas alarm device capable of automatically processing gas leakage

Abstract

The invention provides an intelligent gas alarm device. The device comprises a control system which is connected with a detection system, a power supply system, a display system, a linkage system, analarm system and a communication system and used for controlling the whole intelligent gas alarm device. The detection system adopts two or more gas sensors arranged in parallel to ensure that the alarm device continues to work after one of the sensors fails, is used for detecting the gas concentration, is connected with the control system and sends the detected gas concentration value to the control system; the power supply system is used for supplying power to the whole intelligent gas alarm device; the display system comprises a state indicating lamp and a liquid crystal display screen; thelinkage system is connected with the power supply system and the control system, and the linkage system opens a window, closes a gas electromagnetic valve or closes an air switch according to an instruction of the control system and requirements; the alarm system comprises an LED flashing lamp, a buzzer and a voice alarm; and the communication system is used for enabling the intelligent gas alarmdevice to have a wireless communication function.

Description

technical field [0001] The invention relates to the technical field of natural gas alarms, in particular to an intelligent natural gas alarm device that can automatically handle gas leakage. Background technique [0002] With the improvement of people's material living standards, gas is more and more used in daily life. The popularity of gas has improved production efficiency and the quality of life of citizens. However, during the use of gas, accidents such as fire, explosion and poisoning caused by gas leakage occur from time to time, which pose a serious threat to people's lives and property safety. Therefore, the safe use of gas has always been the top priority in gas applications. . [0003] The composition of natural gas is mainly methane, with small amounts of ethane, propane, butane and other minor gases. Natural gas itself is colorless, odorless, and less dense than air, so it will run upwards if it leaks. Install a gas alarm at a certain distance above the gas ...

AI Technical Summary

Problems solved by technology

[0006] 1) Existing gas alarms are preset with a certain dangerous gas concentration threshold. When the detected gas concentration exceeds this threshold, it will suddenly enter a dangerous alarm state. There is a defect that the gas leakage judgment concentration threshold is single, and it cannot Changes are intelligently staged

Moreover, the sudden high-decibel dangerous alarm sound will cause users to panic, especially to the elderly or children.

In addition, fixing a gas threshold cannot eliminate false alarms of suspected leaks caused by interfering gases, etc. The corresponding gas source cut-off device and remote alarm will cause inconvenience and nuisance to users, and in case of false alarms, the alarm signal will be sent to natural gas maintenance or fire protection The actions of other departments will inevitably add unnecessary workload to the relevant departments;

[0007] 2) The existing gas alarm only includes a gas sensor, which has the defect that the function of the gas alarm will fail after the sensor fails;

[0008] 3) When the gas leakage is not resolved in time, the gas alarm does not have an automatic shutdown function, and there may be a risk of fire caused by electric sparks caused by the alarm action
