Overlapping extension centralized monitoring electric power supply system

Abstract

The invention discloses a covering and extending centralized monitoring power supply system, which arranges at least one monitoring power supply mainframe, a plurality of monitoring power supply slavemachines connected with the monitoring power supply mainframe, and a signal detector connected with the monitoring power supply slave machines between BTS and a covering and extending system. The DCoutput by the monitoring power supply mainframe is transmitted to the monitoring power supply slave machines via RF cables. The monitoring power supply slave machines supply power for a trunk amplifier, so as to realize central power supply for the covering and extending system. Monitoring control signals output by the monitoring power supply mainframe are transmitted to the monitoring power supply slave machines. The monitoring power supply slave machines transmit alarm information to the monitoring power supply mainframe to realize the central control of the covering and extending system. Adopting the invention can effectively overcome the insufficient that BTS and a plurality of trunk amplifiers take a dispersion state, can process central monitoring for a plurality of trunk amplifiersvia the system, and can process the central power supply for a plurality of trunk amplifiers in the covering and extending system.

Description

technical field [0001] The present invention relates to the centralized monitoring and centralized power supply technology of the coverage extension system, in particular, relates to a kind of centralized monitoring of the active equipment (such as trunk line amplifier) ​​and coverage links in the coverage extension system, and the coverage extension system A system in which the active devices in the system are centrally powered. Background technique [0002] As the number of urban high-rise buildings continues to increase, the scale and quantity of the coverage extension system in the building are also increasing. Currently, in the construction of the building's coverage extension system, BTS and active equipment in the system, such as trunk amplifiers, are in a decentralized state. Figure 23 Shown is a schematic structural diagram of the coverage extension system, which includes a BTS placed in a computer room on a certain floor of a building, and trunk amplifiers 1 and N...

AI Technical Summary

Problems solved by technology

[0003] 1. Each trunk amplifier in the system adopts the scheme of single-point mains power supply and single-point monitoring. The disadvantage of this scheme is that if the mains power fails on a certain floor, it will cause the trunk amplifier on this floor to stop working and make the coverage of the trunk amplifier The extension system stops working and cannot give an alarm;

[0004] 2. A single trunk amplifier uses one number, which wastes a lot of number resources;

[0005] 3. If the current monitoring system is not upgraded, it will be difficult to access the network management system of the new protocol;

[0006] 4. It is impossible to monitor the trunk amplifier without the monitoring module;

[0007] 5. The current SMS platform mode is not safe and reliable, and it is easy to block and lose packets
