摘要
设计了以STM32F103VBT6单片机为核心的车载动态称重仪表,应用应变传感器和24位模拟数字转换器Hex710获得称重信号,对信号进行处理获得所载货物重量并在仪表上显示,同时该仪表提供RS232接口,把重量数据传输给上位机GPS实施远程监控。详细论述了称重原理及软件算法并设计了硬件电路。实验结果表明仪表能够满足精度要求并实时将重量信息传到监控平台上。
Taking STM32F103VBT6 MCU as a core,on-vehicle WlM （Weighting-in-Motion） instrument is designed in this paper. Strain sensors and 24-bit analog-digital converters are used in this design for weighting signal.The weight of goods con- tained by vehicle can be measured with the signal conducted by MCU,meanwhile the instrument provides an UART-RS232 interface,which transfers data to remote control platform with GPS.The theory of weighting and software algorithm are intro- duced in detail,and the hardware circuit is （：liven.
