Base station power supply network system and base station emergency power supply method

Abstract

A base station power supply network system comprises a core power supply network which is formed by sequentially connecting a plurality of base stations to form an annular loop. Each base station comprises an AC/DC (Alternative Current/Direct Current) two-way DC-DC converter, a detection module and an energy balance module, wherein the AC/DC two-way DC-DC converter is used for sending a DC high voltage current to adjacent base stations or receiving the DC high voltage current; the detection module is used for controlling the AC/DC two-way DC-DC converter to send a detection current to the adjacent base stations, and confirming an optimal voltage value and a current value for sending the current through comparing the sent current with the received current; and the energy balance module is used for controlling the local AC/DC two-way DC-DC converter to supply power for a base station with abnormal power fluctuation. The invention further provides a base station emergency power supply method. According to the base station power supply network system and the base station emergency power supply method, base station power supply systems which are mutually independent originally are connected to form an annular power supply network, and each base station in the network can obtain power supply support from all other base stations.

Description

technical field [0001] The invention relates to a base station power supply network system and a base station emergency power supply method, in particular to a base station DC high voltage remote power supply network system. Background technique [0002] With the development of communication technology, various communication network terminal devices have increased in a large number, such as corridor switches, global eyes, WIFI wireless coverage equipment, and microcells, optical transceivers, dry amplifiers, repeaters, 3G base stations, etc. in indoor coverage systems. There are many types of equipment, large quantities, and poor installation conditions, and their failure rate is much higher than that of equipment in the computer room. [0003] In 3G construction, based on the characteristics of the new generation of 3G mobile communications, BBU+RRU is generally used for signal distributed coverage, in which remote equipment (such as RRU, microcell, optical transceiver, opt...
