Abstract

The invention discloses a receiving antenna diversity fault detection method and device. The receiving antenna diversity fault detection method comprises the following step: calculating the signal intensity of each diversity for many times in a preset time, selecting a plurality of groups of signal intensity as effective detection data according to a pre-scheduled section principle, detecting the fault or fault recovery of each diversity for many times according to the plurality of groups of effective detection data, and determining and reporting that the diversity is in the fault state or fault recovery state when the times of detecting the fault or fault recovery of each diversity reaches the pre-scheduled condition. The receiving antenna diversity fault detection method and device overcome the problem that the diversity receiving abnormity can not be detected completely effectively in the prior art, are easy to implement, achieve the real-time detection effect, save the hardware detection circuit cost and improve the detection accuracy.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for detecting a receiving antenna diversity fault. Background technique [0002] For wireless communication equipment, the normal operation of the antenna feeder system can not only ensure coverage, reduce blind spots, and improve coverage, but also reduce interference, crosstalk, etc., reduce call drop rates, and provide users with high-quality services. The receiving antenna in the antenna feeder system may have problems such as disconnection, connection damage, and antenna channel damage. These problems will affect various indicators of the communication system. Therefore, fault detection and alarms for receiving antenna diversity are very important. [0003] In the prior art, there is a technical solution for realizing anomaly detection, the core idea of ​​which is to use whether the main diversity level difference is greater than a set threshold to...
