Early-warning device of converting station spare channel

Abstract

The invention discloses an early-warning device of a converting station spare channel. The early-warning device of the converting station spare channel comprises a microprocessor, a channel monitoring plate socket, a universal serial bus (USB) interface, a subscriber identity module (SIM) card socket, an indicator light module and a global system for mobile (GSM) chip which are respectively connected with the microprocessor, a power supply and an antenna, wherein the power supply is respectively connected with the microprocessor and the GSM chip, a plurality of channel monitoring plates are inserted into the channel monitoring plate socket; an SIM card is inserted into the SIM card socket; two simulating channels or two digital channels are detected by the microprocessor, and the operation state of the simulating channels or the digital channels is acquired and displayed through the indicator light module; the microprocessor controls the GSM chip to compile warning short messages when the two simulating channels or the two digital channels are out of order, and then the warning short messages are sent to a plurality of mobile terminals through the antenna. The early-warning device of the converting station spare channel detects the condition of a telecontrol channel in real time, reports the operation state to mobile phones of operating personnel by the warning short messages when the channel is out of order, can access to imperative telecommand quantity, and is used as the converting station spare channel.

Description

technical field [0001] The invention relates to an early warning device for a backup channel of 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. [0003] Moreover, due to the fact that the substation RTU (Remote Terminal Unit) equip...

Problems solved by technology

[0003] Moreover, due to the fact that the substation RTU (Remote Terminal Unit) equipment put into operation in the early stage, that is, a remote control device installed in the power plant or substation in the power grid monitoring and control system, has gradually aged, and some products cannot automatically resume operation after device abnormalities In addition, multiple failures occurred in the data channel between some substations and the SCADA system (data acquisition and monitoring and control system) of the district and ground survey, resulting in the interruption of the SCADA system data from time to time, which brings real-time monitoring of power grid data and safe and economical operation. Hidden danger

Once the dispatching finds that the channel is interrupted, the equipment emergency repair team cannot remotely distinguish whether the failure of the transmission channel or the equipment in the station such as RTU is faulty. In order to shorten the data interruption time, the protection team and the communication team are often sent to repair together at the same time, resulting in the efficiency of emergency repair. low
