Abstract

The invention discloses a high-voltage direct-current remote power feeding system and method. The system comprises a microprocessing single chip microcomputer, a matrix-grade high-voltage direct-current two-way DC-DC self-tuning mutual coupling backup module, a matrix-grade high-voltage direct-current nominal load power output sampling module, a matrix-grade high-voltage direct-current impedance characteristic load power output magnitude measuring and sending module and a matrix-grade high-voltage direct-current impedance characteristic load power output magnitude measuring and receiving module. By the adoption of the technical scheme, faults caused by powering on and powering off of channels can be effectively eliminated, the operation utilization rate of communication equipment is increased, the service life of the communication equipment is prolonged, controlling is easy, fault protection action is high, and the failure rate is low.

Description

technical field [0001] The invention relates to the technical field of communication power supplies, in particular to a high-voltage DC remote power supply system and method. Background technique [0002] With the development of communication technology, various communication network terminal devices have increased in large numbers, 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. Due to many system integrators, many equipment manufacturers, many types and quantities of equipment, and poor installation conditions, the 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, and the installation conditions of system terminal equipment (RRU, microcell, optic...
