Problems solved by technology
[0005] Since the mechanical mechanism and design method of the entire antenna, including the frequency band switching control device and the phase shifter transmission mechanism, will vary greatly with different types of antennas, resulting in gap errors introduced by the structure and the range of moving distance and movement affected by the transmission. The force range is uneven, resulting in insufficient gear shifting and slow angle adjustment, which affects the effective and fast adjustment of coverage signals and reduces the experience of mobile users

The present invention provides a method for adjusting a multi-frequency electronically adjustable antenna. The method includes: obtaining the expected rotational speed of the motor in the multi-frequency electrically adjustable antenna, and starting the motor at the expected rotational speed of the motor. If the motor does not complete the predetermined target number of rotations, then The actual speed of the motor is obtained according to the Hall sampling value of the motor; the expected speed of the motor is compared with the actual speed, and the actual speed of the motor is adjusted according to the comparison result until the motor completes the target number of rotations. The invention self-adaptively adjusts the rotation speed of the motor, effectively reduces the vibration of the motor, and increases the reliability of the adjustment; in the invention, the motor rotation adjustment subdivision distance reaches 7.2 degrees of circumference, and the adjustment accuracy reaches 0.1 degrees of circumference, realizing accurate gear shifting, Reduce the angle adjustment error introduced by the inertia and the transmission screw gap, and meet the technical development needs of multi-band fusion electronically adjustable antennas.
Description
technical field [0001] The invention belongs to the technical field of electric-tunable antenna control, and in particular relates to a method for adjusting a multi-frequency electric-tunable antenna. Background technique [0002] With the construction of mobile communication networks, electronically adjustable antennas are widely used in the field of mobile communication, and the management of electronically adjustable antennas has been developed to be managed by the base station network management network. [0003] The network management platform of the electric adjustable antenna communicates through the RS485 serial port, implements the standard AISG2.0 protocol, and remotely issues adjustment commands to the tilt control unit at the electric adjustable antenna end. Each frequency band in the electrically adjustable antenna changes the coverage of the signal by changing the position of the phase shifter according to the adjustment command. The transmission mechanism is ...
