Embodiment Construction

[0023] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0024] The technical solution of the present invention is based on the existing switching power supply equipment, through the integration of the existing technology, and adopts a flexible and changeable AC and DC dual input mode to redesign and develop a weak current well or wall-mounted installation and operation suitable for indoor distribution systems. A new set of power supply equipment.

[0025] At the same time, the technical solution of the present invention is based on the complex power supply conditions and environment of the multi-network integration indoor distribution, and specially designs the DC remote power supply 100-400V / 48V remote rectification module to realize the remote control of the built-in battery of the miniature integrated AC and DC switching power supply equipment for communication. Charging management, and at the same time t...

Abstract

The invention discloses an indoor distributed system integral switch power source and a power supply method of the indoor distributed system integral switch power source. Firstly, an external connection high-voltage direct current is input in a direct current-direct current rectifier module, alternating current commercial power is input in an alternating current-direct current rectifier module, a plumbic acid / lithium-ion two-in-one charging management system monitoring unit is used for starting a plumbic acid storage battery charging management process or an iron lithium battery charging management process according to the types of storage batteries, then staring a cross coupling shielding system and finally conducting outputting. By means of the technical scheme, the power source is small in size and is microminiaturized, high-capacity plumbic acid and lithium-ion batteries can both be installed and used in a compatible mode, the environment temperature characteristic can be well adapted, the charging management on the lithium battery and the plumbic acid battery can be simultaneously achieved, the requirements for flexible and variable installation fields of communication equipment, power supplying and backup time discharging are met, and the building and maintaining cost of the equipment are reduced.

Description

technical field [0001] The invention relates to the technical field of communication power supplies, in particular to an indoor distributed system integrated switching power supply and a power supply method thereof. Background technique [0002] Currently, in the construction of WLAN projects, how to maximize the use of operators' existing resources has become the primary consideration. At present, the indoor distributed systems of operators such as 3G, GSM, CDMA, and PHS have basically covered most buildings. The combined network of WLAN systems and 3G / GSM / CDMA / PHS indoor systems can make good use of existing resources. This networking method has the advantages of fast network construction, low investment, fast recovery, no need for engineering surveys, and uniform coverage signals. [0003] As the signal source of the indoor WLAN, the AP is generally installed in a weak electric well or on the wall, and connected to the indoor distributed system through a jumper connectio...
