Design of non-contact fuel consumption real-time monitoring system for BDS positioning special vehicle

Abstract

The fuel consumption measure is inaccurate and no real-time with the three-scale mete in the special vehicles, so the real-time fuel measurement system is developed with the technologies of ultrasonic sensing, single-chip microcontroller, BDS positioning and wireless communication. An ultrasonic oil level sensor is stuck on the bottom of each tank to detect the remaining oil of tanks accurately. It can avoid destroying the existing equipment structure. BDS positioning module is applied to monitor the location of vehicle. This technology is China complete autonomy. The special wireless transmission module and special network node are set up for transmitting the data of fuel consumption and position. It can guarantee the transmission secure and confidential. And a fuel consumption detection algorithm is studied with BDS measuring distance. The prototype is tested in four different road conditions. The error rate of oil detection on a highway with good conditions is 3.92%. And the measured fuel consumption value is close to the manufacturer’s nominal value. The analysis of experimental data shows that the design of the detection system is reasonable and the fuel consumption detection algorithm is correct and reliable, and real-time fuel detection and positioning for the special vehicles can be realized.
