Automatic monitor for angle of base station antenna and automatic monitoring method

Abstract

The invention discloses an automatic monitor for an angle of a base station antenna and an automatic monitoring method. The monitor and the method utilize an MEMS sensor to accurately measure a lower inclination angle of the base station antenna through the principle of a gravity accelerometer, utilize the principle of a reluctance sensitive device sensor to measure an azimuth angle of the base station antenna and calculate and correct the azimuth angle so as to eliminate the deviation caused by magnetic disturbance measured by the position of the antenna and ensure the measuring accuracy, and utilize GPRS transmission and IP transmission modes to automatically transmit the antenna angle data obtained by measuring to a network management center. The monitor and the method solve the inaccurate problems on installation and adjustment of the base station antenna in the prior modes, solve manual measurement error or instability, solve the measurement error influenced by the magnetic disturbance at the position of the antenna, solve the problem that the antenna angle change is not discovered in time, and solve the problem of time and labor wastes for acquiring the antenna angle information.

technical field [0001] The present invention relates to the wireless field. Background technique [0002] Mobile communication base station antenna azimuth, downtilt, antenna height and performance parameters of the antenna itself determine the coverage of the base station, and as the main engineering parameters of the antenna (antenna azimuth, downtilt and antenna height) are wireless network planning The accuracy of important parameters, antenna azimuth and downtilt is an important factor affecting the call quality and perception of mobile users. How to quickly obtain the precise value of the antenna angle? It is particularly important for wireless network planning and optimization. [0003] At present, the azimuth and downtilt angle of the antenna of the mobile communication base station are obtained manually on site through visual measurement of instruments such as a compass (compass) and an inclinometer.

AI Technical Summary

Problems solved by technology

[0007] 1. Due to the different experience and construction methods of construction personnel in actual engineering construction, manually measuring the azimuth and downtilt angle of mobile communication base station antennas requires engineering and technical personnel to use a compass to manually determine the azimuth, and also requires engineering and technical personnel to pass Visually inspect the low-accuracy scale markings represented on the antenna's mounting bracket, identifying slopes that can lead to differences in engineering personnel's skill or manual measurement methods, resulting in incorrect or unstable measurements

Unable to accurately meet the design requirements

[0008] 2. In order to obtain the angle information of the base station antenna, engineers and technicians must directly climb up the base station antenna installed on the multi-storey building or iron tower, and use a compass at the antenna position. Due to the magnetic interference near the iron tower, measuring near the iron tower will cause more big error

It is generally required to have a certain distance away from the iron tower, and use a compass to prevent magnetic attraction! As well as manually measuring the azimuth and downtilt of the antenna by visually identifying the scale line where the mechanical pointer of the measuring instrument is located, the accuracy is not high

[0009] 3. Due to man-made or natural factors, the antenna angle cannot be detected and adjusted in time, which makes the actual value of azimuth and downtilt angle deviate from the design value

[0010] 4. In actual engineering maintenance, technicians need to carry instruments to the site to manually measure the angle of the base station antenna, which increases manpower and material resources; for some special occasions, it brings inconvenience to technicians on-site measurement

[0011] The above disadvantages not only need to increase manpower and material resources, but also easily lead to the fact that the actual coverage of the base station does not match the designed one, resulting in unreasonable base station coverage, or co-frequency and adjacent frequency interference, resulting in a decline in communication quality and affecting customer perception.
