Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0031] figure 1It is a structural diagram of the device for realizing the warning of the standing wave ratio of the base station antenna according to the present invention. The power of the reflected signal reflecting the standing wave ratio of the terminal load at the antenna port is sampled by the coupling port of the directional coupler 111 and sent to the fixed attenuator 112 to further adjust the strength of the sampled signal so that it falls within the optimal detection range of the detection device used. The attenuator generally uses a simple resistance attenuation network, and its attenuation depends on specific design parameters such as directional coupler coupling degree, detector type, optimal detection range, output amplitude index, etc. The detector 113 is used to transform the power of the sampled reflected signal into a DC vol...

Abstract

This invention discloses a realization device and a method for base station antenna stationary-wave ratio alarm, in which, a digital signal process module samples the inverse power detecting signals, processes the sampled digitalized information and outputs the stationary-ratio alarm signals by calibrating the antenna aperture stationary-ratio and detecting the inverse power, which is only necessary to test the reverse signal power to realize the antenna stationary-wave ratio alarm.

Description

technical field [0001] The invention belongs to the field of mobile communication, in particular to wireless communication equipment such as a PHS base station with an antenna standing wave ratio warning function. Background technique [0002] With the continuous development of modern mobile communication technology, wireless service operators have higher and higher requirements for the maintainability of wireless networks. Regardless of wireless equipment or base station equipment, they can detect in time that the antenna standing wave ratio is too large (usually due to various Caused by poor physical connection due to various reasons) and alarm, and requires a very low probability of false alarm and missed alarm. At present, the industry mainly uses the VSWR alarm circuit based on the reverse power detection technology before comparison to realize the antenna VSWR alarm function of the wireless transmitting device. This method is referred to as the traditional VSWR alarm c...
