Description

technical field [0001] The present invention relates to the technical field of gas source positioning, relates to a gas source positioning device, in particular to a system and an algorithm for gas traceability based on sensors mounted on an Arduino car. Background technique [0002] In recent years, many chemical accidents have occurred in my country's chemical industry, seriously threatening the lives of the people, causing huge economic losses, destroying the ecological environment, and even seriously affecting social stability. According to the announcement of the State Administration of Work Safety, about 70 % of accidental explosions of hazardous chemicals are caused by leakage, and once a dangerous gas leakage occurs, it is extremely dangerous to manually investigate the leakage and the source of the leakage, such as the aging of urban pipelines or the leakage of toxic industrial gases. It will cause huge losses to people's life and property safety. Once a dangerous ga...

Problems solved by technology

[0013] (1) The ultrasonic positioning accuracy is high and the error is small, but the ultrasonic signal transmission attenuation is serious, the positioning range is limited, the equipment cost is high, and it is only suitable for indoor positioning applications in specific environments

[0014] (2) Infrared indoor positioning accuracy is high, but due to the wavelength characteristics infrared rays cannot penetrate obstacles and can only be transmitted within a straight line of sight, the effective distance is short, the cost is high, and the practical application is not large

[0015] (3) Ultra-wideband (UWB) positioning accuracy is very high but the cost is also high

[0016] (4) Radio frequency identification (RFID) technology has a large transmission range and low cost, but the working distance is short, the longest is only tens of m
