Description

Technical field

[0001] The invention relates to the wireless field. Background technique

[0002] The antenna azimuth angle, downtilt angle, antenna height and the performance parameters of the antenna itself determine the coverage of the base station, and the main engineering parameters of the antenna (antenna azimuth angle, downtilt angle and antenna height) are planned by the wireless network Important parameters, the accuracy of the antenna azimuth and downtilt angles are important factors affecting the quality and perception of mobile users. How to quickly obtain the accurate value of the antenna angle? It is particularly important for wireless network planning and optimization.

[0003] At present, the azimuth angle and downtilt angle of mobile communication base station antennas are obtained by visual observation with instruments such as compasses (north needles) and gradient meters. The general methods are:

[0043] (1) Principle of acceleration sensor

[0044] The most basic principle of an acceleration sensor is that a certain medium is deformed due to acceleration, and the deformation is measured and converted into a voltage output by a related circuit. This voltage represents the magnitude of acceleration.

[0045] The sensor is mainly composed of a polysilicon mechanism using surface micromachining and a differential capacitor. The polysilicon structure is supported by a polysilicon spring, is located on the top of the wafer, and is connected to the motion center plate of the differential capacitor. Two square waves wi...
