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.
