Problems solved by technology

However, for a large antenna array, when some abnormalities occur in individual vibrators inside the antenna, such as weak soldering, short circuit, or broken mechanical structure of the vibrator, the standing wave of the RF signal at the antenna feeder connected to the RF front-end circuit will not appear obviously abnormal, so it cannot be monitored. Abnormality of the vibrator inside the antenna array

Abstract

The invention discloses a method and a system for monitoring a base station antenna element and an integrated monitoring device. The method, the system and the integrated monitoring device are used for monitoring whether is base station antenna element is abnormal or not. The method includes: performing detection and analog to digital conversion to an acquired transmission signal of the base station antenna element to obtain a direct current signal and a digital signal of the transmission signal; determining variation amplitude of the digital is a preset time period, determining that the antenna element is abnormal when the variation amplitude is larger than a preset variation amplitude threshold, or else, determining that the antenna element is normal.

Description

[0001] The application of the present invention is a divisional application of the invention application with the filing date of September 08, 2011, the application number of 201110265386.5, and the title of the invention being "A Monitoring Method, System and Integrated Monitoring Equipment for Base Station Antenna Vibrators". technical field [0002] The invention relates to the field of communication technology, in particular to a monitoring method, system and integrated monitoring equipment of a base station antenna oscillator. Background technique [0003] The base station antenna generally adopts the method of forming an array of vibrators to form an electromagnetic beam with high gain and meet certain shaping requirements, which is used to transmit wireless communication signals. At present, base station antennas equipped with more oscillators are gradually becoming the mainstream, especially Time Division Synchronized Code Division Multiple Access (TD-SCDMA, Time Divi...
