摘　　要：低压电力载波通信要求较高,当前电力信息采集系统存在采集不稳定、实时性差以及无法采集所有低压电力用户信息等问题,因此面向低压电力,以扩频通信作为技术支撑,提出一种用户信息自动采集系统。利用数据集中器、数据采集终端、载波电能表、手抄机以及主站等组件,构架低压电力用户信息自动采集系统结构框架,采用主站部分、集中器控制部分、终端载波部分以及集中器载波部分,基于对应模块运行环境,构成自动采集系统软件部分,最后凭借扩频通信技术设计码分多址策略,保持发送端与接收端的扩频码序列相一致。实验结果表明,所建系统的采集精准度与采集效率优势显著,将系统应用于复杂的电力实际场景内,依旧能得到较好的通信性能,且具有优越的免疫性能与接收灵敏度。Low voltage power carrier communication has high requirements.The current power information acquisition system has the problems of unstable acquisition,poor real-time performance and unable to collect all low-voltage power user information.Therefore,for low-voltage power,a user information automatic acquisition system based on spread spectrum communication is proposed.Using data concentrator,data acquisition terminal,carrier energy meter,hand reading machine and master station and other components,the structure framework of low-voltage power user information automatic acquisition system is constructed.The main station part,concentrator control part,terminal carrier part and concentrator carrier part are adopted to form the software part of automatic acquisition system based on the corresponding module operating environment.Finally,spread spectrum communication is used technology design code division multiple access strategy to keep the spread spectrum code sequence of transmitter and receiver consistent.The experimental results show that the acquisition accuracy and efficiency of the system have significant advantages.When the system is applied to the complex actual power scene,it can still get better communication performance,and has superior immune performance and receiving sensitivity.
