Problems solved by technology

[0006] However, there is a certain range for adjusting the length and angle of the phase shifter of the electronically adjustable antenna. Exceeding this adjustment range will cause permanent damage to the phase shifter. The electronically adjustable antenna control device cannot accurately obtain the relative moving position of the phase shifter after adjustment, nor can it eliminate the accumulated position error after multiple adjustments of the phase shifter

Embodiment 1

[0027] Such as figure 1 and 2 As shown, the electronically adjustable antenna 1 is located on the top of the mobile base station tower, and its downtilt angle can be adjusted by the rotating shaft of the phase shifter of the electrically adjustable antenna 1. The controller includes a housing 21, a motor 22 and an electric antenna downtilt angle control module 23 are arranged in the housing 21; the front end 221 of the rotating shaft of the motor 22 is connected with the rotating shaft seat 11 outside the electric antenna 1 through a connector 4 and a connecting nut 3, Wherein the connector 4 passes through the shell front cover 211 of the electronically adjustable antenna controller; the electronically adjustable antenna downtilt angle control module 23 is connected to the motor 22, and the electrically adjustable antenna downtilt angle control module 23 is used to output control signals to control the rotation axis of the motor and then control the rotation of the phase shi...

Embodiment 2

[0030] The difference from Embodiment 1 is that the two limit switches 25, 26 are respectively arranged on a limit plate 27 arranged parallel to the extension section of the rear end of the motor rotation shaft, see image 3 shown.

Embodiment 3

[0032] Different from Embodiment 1, the motor 22 is a motor with a deceleration mechanism, and the downtilt angle control module of the electric adjustable antenna is a printed circuit board, which is arranged in parallel with the extension section of the rear end of the motor rotating shaft, and the A strip-shaped slot is provided on the printed circuit board, and the slider can move linearly along the strip-shaped slot driven by the rotating shaft of the motor, while two limit switches 25, 26 are respectively arranged on the strip-shaped slot of the printed circuit board The two end edges of the bar groove, see Figure 4 shown.

Abstract

The invention relates to a control device of an electrically adjusted antenna, comprising a motor and a declinational angle control module of the electrically adjusted antenna, wherein the motor is provided with a rotating shaft; the front end of the rotating shaft of the motor is connected with a phaser rotating shaft of the electrically adjusted antenna; and the declinational angle control module of the electrically adjusted antenna is connected with the motor. The control device of the electrically adjusted antenna is characterized in that the rear end of the rotating shaft of the motor is provided with an extending section extending outwards and provided with a screw thread thereon, and a slide block is sleeved on the extending section at the rear end of the rotating shaft of the motor in a sliding way; the control device of the electrically adjusted antenna also comprises two limit switches which can be triggered by the slide block, the distance between the two limit switches is consistent with the mechanical adjustment range of the electrically adjusted antenna, and the output ends of the two limit switches are connected with the declinational angle control module of the electrically adjusted antenna. Compared with the prior art, the invention has the advantages of accurately obtaining the moving distance of a phaser and having simple structure and convenient use.

Description

technical field [0001] The invention relates to an electric adjustable antenna control device, which is used in the electric adjustable antenna control device for changing the driving and position of the electric adjustable antenna in a mobile communication antenna system. Background technique [0002] With the increasing demand for mobile communication systems, domestic and foreign operators have higher and higher requirements for network quality, especially for dense urban areas and high-floor areas, requiring large antenna downtilt angles, dense cell coverage, and mutual interference Small, general mechanical antennas are difficult to meet these requirements, and only electrically adjustable antennas can meet the above requirements. Because the electric adjustable antenna can change the phase of the collinear array antenna oscillator, change the amplitude of the vertical component and the horizontal component, and change the field strength of the composite component, so t...
