Abstract

The application discloses a primary power-off comprehensive manager in the field of communication equipment, and the manager comprises an MCU microprocessor, a clock chip, an LED display nixie tube, an LED display drive chip, an LED indication lamp, an output control relay, an AD conversion data collection element, and a DC-DC power supply element. The signal input terminal of the microprocessor is in electric signal connection with the signal output terminals of the AD conversion data acquisition element and the clock chip, and the signal output terminal of the microprocessor is in electric signal connection with the signal input terminals of the LED display driving chip and the LED indication lamp. And the signal output terminal of the LED display driving chip is in electric signal connection with the signal input terminal of the LED display nixie tube. According to the invention, the protection function of the storage battery during the period that the communication base station switching power supply monitoring module is damaged or no accessory exists is compensated, the service life of the storage battery is effectively prolonged, and the defect that the high-frequency repeated connection / disconnection of a primary power-off control relay (LLVD) cannot be solved due to the common appearance of the communication switching power supply equipment is overcome at the same time.

Description

technical field [0001] The invention belongs to the field of communication equipment, in particular to a comprehensive manager for one-time power-off. Background technique [0002] The switching power supply of existing communication base stations has the following problems: the logic and function of the original one-time power-off control part cannot meet the needs of the actual working environment. Cause frequent flash disconnection, and even damage the main communication equipment; night is the non-assessment period of the operator's technical indicators, and after 0:00 at night is also the low-peak period for mobile phone users. The original switching power supply has no night power management function, and it will The battery is exhausted during the invalid period, but there is no electricity available during the valid period. [0003] During the use of the lead-acid battery pack, sulfide crystallization and water loss of the plate appeared, which led to an increase in...
