摘要
利用Proteus仿真软件开发信号真有效值测量仪表,在PC机上采用虚拟仪器软件LabVIEW,对单片机采集到的数据进行显示和保存.设计信号处理电路,编写单片机程序和基于计算机的监控程序,在系统开发中采用Proteus、LabVIEW、Keil C51和虚拟串口连接软件进行联调,模拟整个系统的运行.仿真结果表明,该系统能够准确测量信号的真有效值,并可以实现下位单片机系统与上位计算机的串口通信仿真.
The paper discusses the method of designing TRMS voltage instrument using Proteus.The scheme for processing,displaying and saving data was introduced,which is based on virtual instrument software—LabVIEW.The signal processing circuit and software were designed.Proteus,LabVIEW,Keil C51 and the virtual serial ports software were adopted in this system measuring exploitation.The serial-port communication between MCU system in Proteus and LabVIEW was simulated.The simulation results indicated that the system can precisely measure the TRMS of voltage,and can simulate the serial communication between lower machines and upper machines.
