Problems solved by technology

[0004] However, because the existing technology is aimed at the detection of absolute levels, and the RTWP value is set according to the internal properties of the receiver, when the receiver is not faulty (such as disconnection of the antenna feeder connection, large insertion loss due to poor connection, etc.), due to the reception The performance of the receiver itself has not changed, so the RTWP value can still be maintained at a certain value, so the existing technology can only detect the internal fault of the receiver, but cannot detect the fault other than the receiver fault

Embodiment Construction

[0025] After the system has been running for a long time, there may be faults or performance degradation of the receiving channel. The core of the fault detection method of the present invention is to compare the relative value of the RTWP of each receiving channel with the preset threshold value, thereby judging the occurrence of the fault. Faulty receive channel.

[0026] When utilizing the present invention to carry out fault detection, first obtain the RTWP value of each receiving channel; then obtain the relative value of the RTWP value of each receiving channel; then compare the relative value of the RTWP value of each receiving channel with a predetermined threshold value , if the relative value exceeds the predetermined threshold value, it is considered that the performance of the receiving channel is degraded or a fault occurs, and the information of the faulty receiving channel is reported, so that the user can perform equipment maintenance on the faulty device accord...

Abstract

A method for detecting fault of receiving channel includes firstly obtaining value of receiving bandwidth total power for each receiving channel, then obtaining relative value of receiving bandwidth total power for each receiving channel according to obtained value and finally comparing obtained relative value with preset threshold and recording the receiving channel occurred with fault accordingto compared result. The method solves problem that no receiver - fault can not be detected by existing technology.

Description

technical field [0001] The invention relates to a fault detection method, in particular to a fault detection method of a receiving channel in a base station. Background technique [0002] Some common failures in the receiving channel of the base station, such as: antenna failure, connection failure between feeder cable and equipment, receiver failure, equipment internal connection failure, etc., will lead to cell paralysis or performance degradation. Channel failure will result in the loss of the receive diversity function and affect the system's receiving performance; if all the receiving channels fail, it will result in the loss of the receiving function of the entire cell, resulting in a paralysis of the cell. Therefore, when a fault occurs, an alarm must be generated in a timely and accurate manner to prompt the user. [0003] In the prior art, an alarm is judged by using an absolute value of a received channel RTWP (Received Total Wide band Power, total received bandwi...
