Abstract

The invention relates to a wireless repeater, applied to an electrical power system for achieving communication between a main station on the ground and terminal equipment under the ground. The wireless repeater comprises a first communication terminal, positioned on the ground and in communication connection with the main station; and a second communication terminal, positioned under the ground and in communication connection with the terminal equipment, wherein a communication signal of a LoRa system is used for performing wireless communication connection between the first communication terminal and the second communication terminal. The communication signal of the LoRa system is used for performing wireless connection between the first communication terminal on the ground and the second communication terminal under the ground, so that a communication cable is not needed, and the wiring cost is saved. Furthermore, the communication signal of the LoRa system is used for achieving remote signal transmission between the first communication terminal and the second communication terminal; on the other hand, the communication signal of the LoRa system supports multiple orthogonal spreading factors, so that the system capacity of the whole network can be significantly improved, and meanwhile the frequency hopping anti-interference communication capacity is supported.

Description

technical field [0001] The invention relates to the communication field, in particular to a wireless repeater. Background technique [0002] With the continuous development of the Internet, the Internet of Things based on the Internet is also developing faster and faster. In the power system, terminal equipment such as concentrators, distribution transformer monitoring and metering terminals, and load management terminals are installed in the basement; on the other hand, the main station is generally installed on the ground and is far away from the terminal, which makes the main station Communication with end devices is difficult. [0003] In the traditional technical solution, the communication cable is generally drawn from the main station and connected to the terminal equipment to solve the communication problem between the main station and the terminal equipment, but this method is restricted by terrain, transmission distance, etc., and there are installation problems. ...
