Abstract

Abstract: With the obvious improvement in people's quality of life, the use of natural gas is becoming increasingly common. Household natural gas has hidden safety hazards while being hygienic and convenient. There are many gas explosion accidents every year, and life and property are seriously damaged. When the natural gas body leaks a little and the methane concentration in the air is extremely low, the methane sensor may fail to report, and the signal is weak or the early warning signal cannot be processed in time, which brings hidden dangers to the accident of gas explosion. In this paper, an optimized array of antenna arrays is designed based on the ZigBee network. Use multiple MQ-4 sensor arrays to detect the methane concentration in the kitchen, and send the weak signals collected by the four methane sensors to the ZigBee router in the same direction through the four antennas of the ZigBee module. The router timely and accurately transmits to the ZigBee coordinator and uses ZigBee network technology to upload the alarm information to the cell monitoring center through wireless. The simulation test results show that the diamond antenna array can quickly detect the change of methane concentration, and has high sensitivity and reliability.
