An indoor distributed antenna feeder system fault handling device and method

Abstract

The invention discloses an indoor distributed antenna feed system failure processing device and method which are suitable for signal source and direct-current power source combining inlet antenna feeding line remote transmission power supply systems. The indoor distributed antenna feed system failure processing device comprises a failure monitoring module and a power divider automatic control gain module, wherein a directional coupler is arranged in the power divider automatic control gain module, the failure monitoring module is used for monitoring the installation quality and the operation condition of an antenna feed line, and the directional coupler is used for monitoring the power levels coming from an antenna and a communication system. By means of the technical scheme, real-time monitoring on non-break services is carried out on dispersive base station antenna feed systems, and therefore the conditions of a base station can be known at any time to conduct unified and efficient maintenance and management.

Description

technical field [0001] The invention relates to the technical field of communication power supplies, in particular to a device and method for troubleshooting an indoor distributed antenna feeder system. Background technique [0002] In recent years, my country's mobile communication industry has developed at an astonishing speed. In order to improve the network operating environment and improve the quality of network operation, network optimization has become an important topic, and the maintenance of base stations is one of the important aspects. [0003] According to the analysis of the statistical results of mobile network operation quality, the main reason for the decline in mobile communication quality indicators comes from the antenna feeder system, accounting for more than half, and the most important index in the antenna feeder system is matching, that is, the transmission line terminal load (such as antenna) and Whether the characteristic impedance of the transmissi...
