Gas pressure abnormity control system based on Internet of Things intelligent gas meter

Abstract

The invention discloses a gas pressure abnormity control system based on an internet-of-things intelligent gas meter, which comprises an existing internet-of-things intelligent gas meter, a pressure detection device is arranged on the internet-of-things intelligent gas meter, the pressure detection device comprises an arc-shaped hollow spring tube, one end of the spring tube is open and fixed, and the other end of the spring tube is closed and freely stretches out and draws back. The opening is communicated with a gas channel to obtain gas pressure, signal switches are installed on the two sides of the free end of the spring pipe, the pressure detection device monitors the pressure condition of a gas pipeline in real time, switching signals are transmitted to the signal storage processing device when the abnormal condition of overpressure or underpressure occurs, the valve control device is instructed to cut off the gas pipeline, and the communication device is instructed to wirelessly send gas pressure abnormity alarm information, so that automatic control and remote alarm are realized, the pressure abnormity type can be distinguished, and the system has the advantages of low cost and high pressure detection precision.

Description

technical field [0001] The invention relates to a gas pressure abnormal control alarm system, in particular to a gas pressure abnormal control system based on an Internet of Things smart gas meter. Background technique [0002] Natural gas is a high-quality, efficient, green, clean, and low-carbon energy that is widely used in the lives of urban residents. However, natural gas is flammable and explosive, and indoor safety accidents often occur. The safe use of gas has specific requirements for gas supply pressure. Both overpressure and underpressure will cause abnormal combustion conditions of natural gas, and even cause gas leakage accidents. Therefore, it is necessary to alarm and close the valve in the case of overpressure or underpressure of the gas supply to ensure the safety of gas consumption. In reality, by using Existing chips and modern communication technologies constitute some Internet of Things gas meters on the market, which have realized functions such as remo...

[0002] Natural gas is a high-quality, efficient, green, clean, and low-carbon energy that is widely used in the lives of urban residents. However, natural gas is flammable and explosive, and indoor safety accidents often occur. The safe use of gas has specific requirements for gas supply pressure. Both overpressure and underpressure will cause abnormal combustion conditions of natural gas, and even cause gas leakage accidents. Therefore, it is necessary to alarm and close the valve in the case of overpressure or underpressure of the gas supply to ensure the safety of gas consumption. In reality, by using Existing chips and modern communication technologies constitute some Internet of Things gas meters on the market, which have realized functions such as remote meter reading, paid recharge, gas leakage monitoring, etc., improving the management efficiency of gas companies and bringing convenient services to users. Refer to Figure 5 , its main principle structure is that it is equipped with a metering device, a model storage and processing device, a communication device and a valve control device. When an abnormal situation occurs, an alarm message is issued, and the model storage and processing device performs calculation and processing according to the externally detected data, and issues ga
