摘要
针对现有电磁发射机的研究现状和实际工作情况,设计了一种基于DSP和FPGA的可控源电磁发射机的监控系统。具体地,详细介绍了下位机设计方案,主要包括硬件选型、信号处理电路、RMS检测电路、RS485通信电路及Modbus RTU通信协议。上位机基于LABVIEW平台,具备人机交互界面友好、易于操作及图形语言强大的特点。上位机主要用于对下位机进行指令控制与信息通信,实时显示电压、电流及温度,并保存关键数据到数据库。实际运行中,本系统稳定可靠,实时性高,保障了实时监测。
In view of the current research status and actual work of electromagnetic transmitter,a monitoring system of controllable source electromagnetic transmitter based on DSP and FPGA was designed. This paper introduces the design scheme of the lower computer in detail,including hardware selection,signal processing circuit,RMS detection circuit,RS485 communication circuit and Modbus RTU communication protocol. The host computer is based on the platform of LABVIEW. It has the characteristics of friendly human-computer interaction interface,easy operation and powerful graphics language. The upper computer is mainly used for command control and information communication of the lower computer,real-time display of voltage,current and temperature,and save key data to the database. In actual operation,the system is stable,reliable and real-time,which ensures real-time monitoring.
