Combustible gas leakage detection device

Abstract

The invention belongs to the technical field of a communication technology and a detection technology, and discloses a combustible gas leakage detection device, which comprises an electromagnetic valve (1), a gas sensitive element (2), a GPRS (General Packet Radio Service) transmitting module (3), a control module (4), an alarm module (5) and a switch (6), wherein the control module (4) is connected with the GPRS transmitting module (3); the electromagnetic valve (1) is connected with the control module (4); the alarm module (5) is connected with the control module (4); the gas sensitive element (2) is connected with the control module (4); and the electromagnetic valve (1) is arranged on gas pipeline. The GPRS transmitting module is controlled by the control module to transmit gas leakage information; the control module is timely communicated with a supervision department; a countermeasure is timely taken; and the electromagnetic valve is arranged, so that leakage gas can be automatically plugged to prevent danger from being further expanded.

Description

technical field [0001] The invention belongs to the fields of communication technology and gas detection, and in particular relates to a combustible gas leakage detection device. Background technique, [0002] In recent years, the utilization rate of natural gas and coal gas in every household is very high, which provides guarantee for the daily life of urban residents. However, while people enjoy the convenience brought by natural gas and coal gas, accidents of natural gas and coal gas leakage occur from time to time. The residents of this house suffer losses or endanger their lives. When encountering a fire source, it may cause an explosion and bring disaster to other neighbors. The loss is very heavy. Threat to human life and property. [0003] Existing coal gas and natural gas leakage inspections are mainly carried out manually or using instruments, which have many disadvantages: coal gas and natural gas users need to be screened one by one, and the detection cannot be ...

Problems solved by technology

[0003] Existing coal gas and natural gas leakage inspections are mainly carried out manually or using instruments, which have many disadvantages: coal gas and natural gas users need to be screened one by one, and the detection cannot be carried out when the user is not at home. At the same time, the timeliness of finding gas leakage It is also very poor, and it is impossible to detect and find danger in time; during detection, it needs to be in direct contact with the combustible gas in the pipeline, and there is a pressure loss to the gas supply during measurement

This method must be blocked manually. If there is no one at home and the leakage time is too long, it will also cause major safety hazards or accidents.

[0006] It can be seen that most of the existing technologies can only enable the alarm function, and the information is not transmitted to a special department through communication means, nor can it take the means of automatic sealing at the first time when the alarm occurs in the event of a leakage accident. To prevent a large amount of dangerous gas leakage
