Intelligent maintenance system and method for communication base station standby power supply

Abstract

The invention discloses an intelligent maintenance system and a method for a communication base station standby power supply. the system comprises one or more monitoring terminals in mutual two-way data communication, a server and a client located in a remote operation and maintenance center, wherein each monitoring terminal comprises a detection module, a charging / discharging control switching module, a temperature / humidity measurement module, a computer room power measurement module, an ARM processor and a power supply module; a battery pack is switched between a float charging circuit and a discharging loop via a DC contactor; the DC contactor is switched via the switching module; output ends of the detection module, the temperature / humidity measurement module and the computer room power measurement module are all connected with the ARM processor; and the input end of the charging / discharging control switching module is connected with the ARM processor and the output end is connected with the DC contactor. According to the system and the method of the invention, scientific maintenance and intelligent management on the base station standby power supply can be realized, the service life of the battery is prolonged, reliability of the standby power supply is improved, and the operation and maintenance cost is saved.

Description

technical field [0001] The invention relates to an intelligent maintenance system and method for a backup power supply of a communication base station. Background technique [0002] Communication base stations mostly use lead-acid battery packs as their independent backup power supply, so that in the event of a power outage or grid failure, the lead-acid battery pack will independently power the equipment in the computer room, thereby avoiding major accidents and ensuring signal stability and smooth communication . As a backup power source for communication base stations, the life of lead-acid battery packs has a major impact on the reliability and stability of the communication system. In order to ensure the service life of the lead-acid battery pack, it is necessary to carry out routine maintenance on the battery pack. [0003] However, at present, communication operators have some problems in the management and maintenance of lead-acid battery packs, which are mainly re...

AI Technical Summary

Problems solved by technology

For example, due to the mains power outage, a set of lead-acid batteries has just completed a discharge before maintenance, so this routine maintenance work may become an act of excessive discharge or frequent charging and discharging for the batteries, not only It will not play the role of reasonable maintenance, but will have a negative impact on the performance of the battery

[0007] 2. The maintenance work is cumbersome and the maintenance cost is too high

In addition, once the lead-acid battery of the base station needs to be discharged and maintained, it is necessary to carry bulky special charging and discharging equipment. In the field, wait for the lengthy discharge process to end before reinstalling the battery into the base station power system before leaving

[0009] This cumbersome on-site work mode not only has high labor intensity and low work efficiency, but also increases the cost of manpower and material resources.

More importantly, the effect of the work mainly depends on the operator's business proficiency and sense of responsibility. If there is a manual operation error, it will affect the normal use of the lead-acid battery pack.

Moreover, dedicated discharge equipment is usually bulky and not easy to carry. Since there are many communication base stations and they are distributed in different areas, this also brings challenges to operators in deploying maintenance personnel.

[0010] 3. Low repair ability, frequent battery replacement

[0013] The current regular inspection maintenance method belongs to the category of after-the-fact maintenance, and the working method is traditional and extensive, which is not reasonable enough
