摘　　要：以采用微波等离子CVD法合成金刚石现场设备的数据采集和通信为研究内容,设计基于Modbus/TCP协议与RS-485通信协议的数据采集与通信系统。系统以西门子S7-1200PLC为控制内核,微波发生器GMP G4以及质量流量计FCST1000作为硬件核心。通过分析Modbus/TCP协议的报文结构以及RS-485通信协议的数据传输帧格式,在西门子TIA portal软件中进行程序设计,实现PLC对微波电源以及质量流量计的数据采集与通信。经现场运行表明,该系统稳定可靠,能够满足设计要求。Focused on the data acquisition and communication of the diamond field equipment synthesized by the microwave plasma CVD method, a data acquisition and communication system based on Modbus/TCP protocol and RS-485 communication protocol is designed. The system adopts Siemens S7-1200PLC as the control core, microwave generator GMP G4 and mass flow meter FCST1000 as the hardware core. Through the analysis of the message structure of the Modbus/TCP protocol and the data transmission frame format of the RS-485 communication protocol, the program is designed in the Siemens TIA portal software to realize the data acquisition and communication of the PLC to the microwave power supply and mass flowmeter. The on-site operation shows that the system is stable and reliable and can meet the design requirements.
