Channel pre-warning system used for transformer substation

Abstract

The invention discloses a channel pre-warning system used for a transformer substation. The channel pre-warning system is in wireless connection with a plurality of mobile terminals. The channel pre-warning system comprises a central processing unit, a remote measurement data acquisition unit, a remote signaling data acquisition unit, a short message unit, a remote controlling data output unit and a wireless communication unit connected with the short message unit, wherein the remote measurement data acquisition unit, the remote signaling data acquisition unit, the short message unit and the remote controlling data output unit are respectively connected with the central processing unit. The remote measurement data acquisition unit and the remote signaling data acquisition unit respectively collect remote measurement data and remote signaling data. The central processing unit controls the short message unit to convert the received remote measurement data and the remote signaling data into a short message. The central processing unit converts control commands received from the mobile terminals and converted by the short message unit into remote controlling data and outputs the remote controlling data to a relay through the remote controlling data output unit. The system can detect situations of a telecontrol channel in real time, reports an operation state to a mobile phone of an operation person in a short message mode when a channel fault occurs, meanwhile can switch in important remote signaling data and serves as a spare channel of the transformer substation.

Description

technical field [0001] The invention relates to a channel early warning system for a substation. Background technique [0002] At present, the remote control channel of the substation occasionally fails, and the efficiency is low because the cause cannot be identified remotely. All the information of the substation is uploaded to the dispatching center through the channel. If the channel fails, the communication will be interrupted, and all information cannot be uploaded. When a fault occurs, the dispatcher will often notify the operator after discovering it. The operator cannot grasp the information in the station in real time. During the time when the communication is interrupted and repaired, the method of being on duty must be adopted, otherwise, if a fault occurs, the operating personnel and dispatching personnel will not be able to obtain the fault information in time. Contents of the invention [0003] The purpose of the present invention is to overcome the defects...
