摘要
利用STM32F103VE作为处理器,实现了矿用DTU测试系统的设计。系统包含10路电压测试点、1路电流测试点、2路开关量测试点和4路串口测试点。所有测试数据都通过4路串口采用MODBUS协议传送和采集。介绍了系统硬件设计方案和MODBUS协议软件实现过程,并给出了部分电路图和源代码。
It realized design of mine-used DTU testing system which is based on using STM32F103VE as a CPU. The system contains 10 voltage test points, a current test point,2 binary variable test points and 4 serial test points. All testing data is transmitted and collected through 4 serial ports by MODBUS protocol. The scheme of hardware and Modbus software design are introduced, and principle circuit and source code are presented.
