】　本文主要讨论了Modbus 通信协议的R TU 帧格式中常用的错误校验方法,即循环冗余校验法( CRC) 。 提出了Modbus 协议反转CRC 校验的方法,推导了反转CRC 校验快速计算表格,并用C 语言实现了基于快速查 表算法的循环冗余校验程序。-In this paper, we mainly discuss the Modbus communication protocol R TU frame format commonly used in error checking methods, namely, Cyclic Redundancy Check Code (CRC). Modbus protocol proposed inversion method CRC checksum, CRC checksum is derived fast computing inversion table, and C language to achieve a quick look-up table algorithm based on cyclic redundancy check procedure.

利用labview实现串口通信。先安装visa驱动包， 再就是visa read 作用是从串口读取数据，这里面有个read buffer ，从串口读取的数据 visa write向串口写入数据或者是命令 还有visa close 结束串口读取数据，目的是读完数据后，释放串口资源

应用背景该代码用于在线多参数水质监测，测量DO，PH，EC，CHLA和TUR的参数及其温度数值，该代码已测试通过，可以使用，采用RS485串口通信，并运用modbus通信协议。关键技术本项目采用了通过STM32控制模拟开关，渐而控制五个传感器的导通情况，用来控制传感器发送采集到的数据，并将采集到的数据打包起来，发送发给上位机。
