146031-01 Communication Power Supply Equipment

146031-01 is the power and guarantee of the communication industry, which has an important impact on ensuring the quality of communication and plays an irreplaceable role in the communication industry. Because the failure of communication equipment is localised, while the failure of power supply will cause all communication to stop, people regard communication power supply as the heart of the whole communication system. 146031-01 provides guarantee for the reliable operation of railway communication power supply, air-conditioning and environment centralised monitoring system and the safe operation of railway communication.

146031-01 In order to ensure the smooth development of railway communication and the safety and reliability of its communication, the Electricity Bureau of the Ministry of Railways has been carrying out centralised monitoring of communication power supply equipment and its environment since 1997. The monitoring system carries out telemetry, telecommunication and remote control on each independent communication power supply and air-conditioning system and each equipment within the system, monitors the operation status of the system and equipment in real time, records and processes relevant data, detects faults in a timely manner, and notifies the personnel to deal with the faults, so as to realise fewer or unmanned communication bureaus (stations) and centralised monitoring and maintenance management of power supply and air-conditioning to improve the reliability of the power supply system and safety of the communication equipment. The reliability of the power supply system and the safety of the communication equipment are improved.
