基于MODBUS协议温湿度数据采集系统的实现

Realization of temperature and humidity data collecting system using MODBUS protocol

目前卷烟行业对环境温湿度稳定性和准确性要求的不断提高,针对这一情况,在配备了一台温湿度环境试验箱的基础上,制定了一套温湿度传感器的校准方法,设计完善了基于MODBUS协议的数据采集系统,系统包括数据采集模块,数据处理模块和数据显示存储模块,以SQL Server作为后台服务器,系统通信采用MODBUS RTU模式,实现了温湿度传感器校准数据实时采集、显示、存储及查询的功能。

Recently,as the increasing requirement on the stability,reliability and accuracy of environmental temperature and humidity data in the Tobacco Industry,a set of correcting ways of temperature humidity sensors has been fulfilled and a data collecting system based on the MODBUS protocol has been designed and performed with the equipment of a temperature and humidity environment experimental case.The system includes data collecting module,data processing module and data display memory module,which using the SQL Server as the background data server.Moreover,the system communication applies the MODBUS RTU mode,resulting in the successful realization of temperature and humidity data collecting,display,storage and inquires functions.
