Automatic antenna feed fault detection system for distributed antenna system

Abstract

The invention relates to an automatic antenna feed fault detection system for a distributed antenna system. The automatic antenna feed fault detection system comprises a far-end antenna feed system alarm information collection device, an alarm information forwarding device and a network management center, wherein the far-end antenna feed system alarm information collection device comprises a far-end signal emission unit, a multifrequency combiner and an inner antenna additionally attached with inactive passive electronic labels. RUs read serial numbers of the electronic labels attached onto the antenna at regular time, each RU is in charge of collecting and monitoring fault data belonging to antenna feed systems, and all the RUs send the collected fault data and topological structure data belonging to antenna feed sub-systems to a monitoring center. The alarm information forwarding device comprises a near-end signal access unit and an expanding unit. The network management center comprises an alarm information receiving unit and an alarm display unit. The automatic antenna feed fault detection system for the distributed antenna system has the advantages of providing an automatic antenna feed fault detection scheme, reducing cost of labor and material resources, improving detection efficiency, finding problems timely and shortening fault clearing time.

Description

Technical field [0001] The invention relates to the field of mobile communication distributed antenna systems, and is an automatic antenna feeder fault detection system for distributed antenna systems. Background technique [0002] Mobile communication signal indoor coverage is an important part of the mobile communication system. As a new indoor signal coverage method, distributed antenna systems are receiving more and more attention. A distributed antenna system consists of four parts: signal access unit (AU), signal extension unit (EU), remote signal transmission unit (RU), and antenna feeder system. The access unit is responsible for introducing signals from the base station, the extension unit is responsible for distributing the signals to each remote unit, and the remote signal transmitting unit is responsible for sending the signal to the antenna feeder system, and the antenna feeder system finally completes the signal transmission and reception. AU, EU, and RU already h...
