摘　　要：为了提高单相电度表的抄录、校准等工作的效率和准确性,开发了一种基于nRF401无线通信模块。此模块用来实现上位单片机和多个单片机间的无线串行通信,并利用该方法设计了一种新型无线抄表系统,给出了硬件线路图、通信协议、程序流程图及用MCS51汇编语言编写的部分串行通信程序。该抄表系统硬件电路简单、成本低廉、编程方便,能在多台单片机间安全传递数据。In order to enhance the efficiency and accuracy for reading, recording and calibrating single phase electric meters, the nRF401 based wireless communication module is developed. This module was used to realize wireless serial communication between host computer and single chip computers. A novel wireless reading system was also designed by using this method. The hardware circuit, communication protocol, program flowchart and partial serial communication program written by MCS51 assembly language were given. This system features simple hardware circuit, low cost and easy programming, while the data can be safely transfered among single chip computers.
