组态软件与Modbus协议在矿用传感器调校装置中的应用

摘要

In view of problems of no functions of real-time data display and processing, automatic closed-loop control and communication interface of current sensor calibration devices, the paper put forward a method of applying configuration software and Modbus communication agreement in mine-used gas sensor calibration device. The method can connect sensor calibration device with upper computer through a serial port and Modbus communication agreement and single-chip microcomputer, can control entire process of sensor calibration and dynamically collect and process data for each sensor. The practical application showed that the method can realize automation, precision of mine-used gas sensor calibration device, which guarantees safety production of coal mine.%针对现有的传感器调校装置存在缺乏数据实时显示和处理、自动闭环控制、通信接口功能等问题,提出了一种将组态软件与Modbus通信协议应用于矿用气体传感器调校装置的方法.该方法利用串行口和Modbus通信协议将所调校的传感器通过单片机和上位机相连,可实时控制传感器调校的整个过程,并能动态采集、处理各传感器数据.实际应用表明,该方法实现了矿用气体传感器调校装置的自动化、精确化,保障了煤矿的生产安全.
