摘　　要：RS-485是一种平衡传输的串行通信接口标准,采用平衡差分信号传输方式,能够在较长距离和恶劣环境下稳定工作,实现多个设备之间的联网通信,并有效抑制共模干扰.由于对RS-485性能的检测多是实验室理想环境下检测,同实际运行存在明显差异.基于此,文章仿真实际工况下,检测RS-485协议环境中电能表串口软件连续多帧通信性能,以解决电能终端设备的现场运行环境复杂及计量结果不准确等问题.RS–485 is a serial communication interface standard of balanced transmission,using balanced differential signal transmission mode,which can work stably in a long distance and harsh environment,realize networking communication between multiple devices,and effectively suppress common mode interference.Because the testing of RS–485 performance is mostly under the ideal laboratory environment,there are obvious differences from the actual operation.Based on this,the paper tests the continuous multi-frame communication performance of the serial port software of the energy meter in the RS–485 protocol environment under simulated actual conditions,so as to solve the problems such as complex field operation environment and inaccurate measurement results of the power terminal equipment.
