摘　　要：为降低无线跳频通信的误码率水平,实现电表通信数据的无误传输,设计基于Wi-SUN技术的智能电表无线跳频通信系统。将外围跳频电路与内部通信寄存器对接,借助预留信道接口,实现数字频率合成模块与系统通信主机间的应用连接,完成系统的硬件执行环境搭建。在此基础上,借助ALOHA/CSMA协议,对智能跳频码进行定义,通过计算数字通信频率周期数值的方式,实现系统的软件执行环境搭建,联合相关硬件设备结构,完成基于Wi-SUN技术的智能电表无线跳频通信系统设计。对比实验结果显示,与传统基带处理系统相比,基于Wi-SUN技术的通信系统的传输误码率水平更低,可在较短时间内实现对电表通信数据的无误传输。In order to reduce the bit error rate of wireless frequency hopping communication and realize the error-free transmission of electricity meter communication data,a wireless frequency hopping communication system of smart electricity meter based on Wi-SUN technology is designed.The peripheral frequency hopping circuit is docked with the internal communication register,and the application connection between the digital frequency synthesis module and the system communication host is realized with the help of the reserved channel interface,and the hardware execution environment of the system is completed.On this basis,with the help of ALOHA/CSMA protocol,the intelligent frequency hopping code is defined.By calculating the frequency cycle value of digital communication,the software execution environment of the system is built,and the design of the wireless frequency hopping communication system of smart electricity meters based on Wi-SUN technology is completed by combining with the structure of related hardware equipment.The comparative experimental results show that compared with the traditional baseband processing system,the transmission error rate of the Wi-SUN communication system is lower,and it can realize the error-free transmission of the electricity meter communication data in a shorter time.
