Embodiment Construction

[0023] The technical scheme of the present invention is based on the original mobile communication base station intelligent composite signal source (RF) and DC power supply (DC) combined into the antenna feeder remote transmission power supply system by adding indoor distributed antenna feeder system fault monitoring module and power division The built-in directional coupler of the automatic control gain module of the transmitter cooperates with the value of the standing wave ratio (VSWR) or return loss (ReturnLoss) of the antenna feeder (Isolation) and the mathematical model of the voltage / current standard database to realize the indoor distribution system. Judgment of the installation quality and operation of the antenna and feeder lines.

[0024] The indoor distributed antenna feeder system fault processing device is suitable for the remote transmission and power supply system of the signal source and the DC power supply combined into the antenna feeder line, including a fau...

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...
