Real-time Fuel Consumption Detection Algorithm for BDS Positioning Special Vehicle

针对目前特种车辆油量检测采用三刻度式仪表显示方式,存在油量感知不精确、油耗测量不实时的问题,该文采用超声传感、单片机控制、北斗定位与无线通信等技术,开发了北斗定位特种车辆实时油量检测系统,研究了基于北斗定位测距的油耗检测算法。在4种不同路况下对样机进行了测试试验,在路况较好的高速公路上油量检测误差率为3.92%,测得的油耗值与厂家标称值相近。试验数据分析表明,该检测系统设计合理,油耗检测算法正确、可靠,能够实现对特种车辆进行实时油量检测与定位。

In view of the problem that the fuel consumption measure is inaccurate and no real-time with the threescale mete in the special vehicles. The real-time fuel measurement system is developed for the Beidou positioning special vehicle with the technologies of ultrasonic sensing,single-chip microcontroller,BDS positioning and wireless communication. 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.
