Modbus協(xié)議在壓力監(jiān)控系統(tǒng)中的應(yīng)用研究

本設(shè)計包括智能工業(yè)控制器下位機和應(yīng)用組態(tài)王6.51 軟件編制的上位機監(jiān)控程序，兩者通過目前流行的Modbus 協(xié)議通訊。前者應(yīng)用智能專家PID 控制算法，完成對壓力物理
量的控制，后者用于對下位機參數(shù)讀寫，顯示，報警，報表打印等，從而實現(xiàn)了一套完整可靠的工業(yè)監(jiān)控系統(tǒng)。

Abstract: The design include the intelligent industry controller used for lower level computer and the monitoring program used for upper level computer by the kingview 6.51,they take the Modbus for communication which is one of the popular industry field bus protocol. This controller use the advanced intelligence Expert PID controlling arithmetic for the control of pressure.The latter can read-write and display the parameter of the lower level controller, give an alarm , print report forms and etc,which implement a suit of integrated and credible industry monitoring system.
Key words: Visual C++6.0; Real-time monitoring;Modbus protocol; the intelligent industry controller
