基于Modbus现场总线的液体流量测试平台的研究和设计

Research and Design about Liquid Flow Test Platform Based on Modbus Fieldbus

随着机械、化工、纺织等行业的飞速发展和生产规模的不断扩大,人们对生产过程集中监控的要求也越来越迫切,现场总线技术应运而生。文章选择了液体流量作为测量监控的对象,设计了基于Modbus协议的液体流量测试平台,通过编写上位机Modbus协议程序,实现上下位机的协议通讯。测试平台可以快速、实时地采集流量信息并能准确、实时地传输数据,并提供友好的用户界面,方便用户监控,实现了数据监测,数据传输和数据处理保存,对实际的工业化生产提供了很好的参考价值,对同类产品的开发也有一定的借鉴意义。

With the rapid development of machinery, chemicals, textiles and other industries and the continuous expansion of production scale, people＇ s centralized monitoring requirements of the production process, now, has become more and more urgent, the fieldbus technology came into being. This paper selected liquid flow measurement as an object, designed the liquid flow test platform based on Modbus protocol and achieved upper and lower computer communications protocol by writing PC Modbus protocol procedures. The 请健入文字或网站地址,或者上传文档. test platform can quickly gather real-time traffic information and accurate, real-time transmission of data. It also provides a friendly user interface and good value for the actual industrial production, as well as a certain reference for the development of similar products.
