针对现代电力系统通信资源,设计基于TD-LTE的电力通信系统,使其能够将音频或者视频数据传送到电力应急控制基站,为电力顺利通信提供高宽带的通信。使用AT89C51单片机实现系统中总控制器的设计,使其能够实现电力及通信系统两者之间的相互交互;使应急通信车成为信号的中继,利用简单灵活的通信通道实现电力通信系统容量的最大化规划。通过人员能够通过无线单兵设备传送到应急现场,使用天线和功放将收集的数据传送到应急通信车中,保证基于TDLTE的电力通信系统能够实现长距离传输。通过耦合电路连接智能收发器,从而保证收发电路中的存储器能够实现数据的保存,并且将其创建成为收发器单元,对数据进行发送及接受,以此有效提高电力通信系统在通信过程中的效率。通过实验表示,本文所设计的基于TD-LTE的电力通信系统的实用性较高,能够满足电网通信的即时需求。

In view of the modern electric power system communication resource, design of power communication system based on TD-LTE, which can control the base station emergency audio or video data transmission power to provide high bandwidth communication, for electric power communication. The use of AT89C51 MCU design controller in the system, which can realize interaction between power and communication system; make emergency communications vehicles become the signal relay, the maximum capacity of planning implementation of electric power communication system using communication channel is simple and flexible. The staff through wireless individual devices to the emergency site, the use of antenna and power amplifier will collect the data to the emergency communication vehicle, ensure power TD-LTE communication system can realize long distance transmission based on. Connecting smart transceiver by coupling circuit, so as to ensure the memory transceiver circuit can realize the data storage, and will create a transceiver unit, to send and receive data, in order to improve the efficiency of electric power communication system in the communication process. The experiment shows that the power communication system based on TD-LTE designed in this paper is more practical and can meet the instant demand of power grid communication.
