电动轮自卸车载重特别大,准确测量装载物的质量可以解决有效负载不足或超载的问题。设计了一种基于DSP的动态称重系统,介绍了自卸车动态称重模型和称重公式,给出了系统的组成结构和主要电路的设计,讨论了系统软件设计和各个模块的功能,分析了测量精度和误差原因。测试结果表明,该系统能满足称重使用要求,可配备到各系列电动轮自卸车上。
Electric wheel dump truck heavy load, accurate measurement of the quality of the load can solve the problem of insufficient or overloaded payload. A dynamic weighing system based on DSP is designed. The dynamic weighing model and weighing formula of the dump truck are introduced. The composition of the system and the design of the main circuit are given. The functions of the system software and the functions of each module are discussed. The measurement accuracy and error reasons. Test results show that the system can meet the weighing requirements, can be equipped with a series of electric wheel dump truck.
