摘要
针对传统电力通信数据终端在传输中存在损耗过高的问题,设计了一种基于北斗一代的电力数据通信终端。电力数据传输终端的硬件部分由MCU主控芯片、电力通信数据网络接口、数据传输接口、电源管理模块及其他辅助接口等部分组成,介绍了主控芯片的参数和引脚功能,并给出电力通信数据网络接口的电路结构。在终端模块的软件流程设计方面以多模终端程序为中心,实现配电主站中心指令的下达与终端应答反馈信息的及时传递。实验结果显示,设计的终端所需通信成本最高为5.15万元,最低仅为3.25万元,远低于传统终端,设计的终端在电力通信数据传输的完整性方面更具优势,电力数据传输损耗低于传统的终端设计,成本控制效果更好。
Given at the shortcomings of traditional power communication data terminal in transmission,a power data communication terminal based on Beidou generation was designed.The hardware part of power data transmission terminal consists of MCU main control chip,power communication data network interface,data transmission interface,power management module and other auxiliary interfaces.The parameters and pin functions of the main control chip were introduced in detail,and the circuit structure of power communication data network interface was given.Software design of terminal module centered on multi-mode terminal procedure,to achieve the distribution master station center instructions and timely transmission of terminal response feedback information.The analysis of the experimental results shows that the communication cost of the terminal designed is 51 500 yuan,the lowest is only 32 500 yuan,which is much lower than that of the traditional terminal.This shows that the designed terminal has more advantages in the integrity of power communication data transmission,and the loss of power data transmission is lower than that of the traditional terminal design,and the cost control effect is better.
