TECHNICAL FIELD
[0001] The application relates to a concentrator remote relay communication method based on a preemption and priority decision mechanism and belongs to the technical field of power distribution communication. BACKGROUND
[0002] As an important core device of a low-voltage area, in addition to performing local service functions, the concentrator is also responsible for realizing remote data interaction functions with a power utilization information collection master station through a 4G / 5G communication module. In actual operation, due to the high binding of the installation position of the concentrator and the power distribution transformer, the communication performance is often restricted by various objective factors. Factors such as geographical environment, mobile base station coverage, urban building multipath effect, and the like often lead to weak or even complete interruption of the remote wireless communication signal of the concentrator, seriously affecting the real-time performance and completeness of data collection, and bringing great challenges to the normal operation of the power utilization information collection system. Therefore, it is urgent to design a concentrator remote relay communication system, including a unique signal transmission decision method, to ensure effective and orderly transmission of multiple data such as control commands, state commands and service data in a high-quality single channel, so as to ensure stable communication between the concentrator and the master station.
