[Abstract]:Based on the communication resources of the current power system, a kind of power communication system based on time-sharing long-term evolution (TD-TLE) is designed, which can provide audio and video data to the power emergency control base station and provide an effective high-bandwidth channel for the smooth progress of power communication.The system adopts the AT89C51 MCU of ATMEL Company as the main controller to realize the data exchange between the communication system and the power system, and the emergency communication vehicle is used as the signal relay.Through flexible communication channel planning, the capacity of power communication system is maximized. The workers walk the wireless single-soldier equipment to the emergency scene, and use power amplifier and antenna to send the collected data to the emergency communication vehicle.To ensure the long distance transmission of TD-LTE power communication system, through the connection between PL3150 intelligent transceiver and coupling circuit, the transceiver unit is composed of add-in program memory to save the data in the transceiver circuit to realize the receiving and transmitting of power data.Improve the mobile communication ability of electric power communication and meet the real-time requirement of power network communication.The experimental results show that the proposed system is highly applicable.
