基于ModbusRTU的蠕动泵测控系统的设计与研究

摘要

Based on the existing domestic manufacturer production common peristaltic pump BT100 M as the research object, according to the pump body meet Modbus RTU serial port communication proto-col, the pump head drive and motion control is analyzed and the research, and by using PLC of Siemens 224XP system to the overall operation of the equipment for automatic control system design, test and hu-man-machine interface development, to the value of its application and popularization, on its program de-sign method of the Modbus free port communication protocol. According to the research design content on the basis of the original equipment on the upper human-machine interface automatic control, to make it a targeted application in related industrial automatic control field.%以现有国内厂家生产的常见蠕动泵 BT100 M 为研究对象，根据泵体满足串口 Modbus RTU通信协议，对其泵头驱动装置及泵头的运动控制进行分析与研究，并利用西门子224 XP系列PLC对其设备的整体运行情况进行自动控制系统设计、测试及人机界面开发，挖掘其应用及推广价值，研讨其Modbus自由口通信协议的程序设计方法。根据研究设计内容在原有设备的基础上对其进行上位人机界面自动控制改造，使其有针对性地推广应用于相关的工业自动控制领域。
