Abstract

The invention discloses a communication method, a communication device, and a communication system used for scheduling instructions. The communication method comprises steps that a first relay station deployed on a preset position is used to transmit first instruction signals by adopting a broadcasting way; second instruction signals from at least one second relay station are received; the second relay station can be one relay station or a plurality of relay stations in the coverage area of the first relay station; the first instruction signals and the second instruction signals are transmitted by adopting an analog communication way. A technical problem of a conventional digital cluster communication system of inability of an emergency communication system of carrying out communication under a power off condition of a mobile base station is solved.

Description

technical field [0001] The present invention relates to the field of power grids, in particular to a communication method, device and system for dispatching instructions. Background technique [0002] In the power system, there are often emergencies such as power outages or equipment failures. The power emergency command system is a communication system in the power system to deal with emergencies and ensure the safe operation of the power grid. The existing electric power emergency command system mainly adopts the digital trunking communication system. [0003] Under normal conditions, this digital trunking communication system can ensure good command of the emergency communication system. However, in the event of extreme weather, natural disasters, etc., since the digital trunking communication system relies on mobile base stations for communication, for example, The emergency communication system of Daxing Company adopts an 800M digital trunking communication system, whi...
