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 invention provides a method for adjusting a multi-frequency electrically-tunable antenna, and the method comprises the steps: obtaining expected rotating speed of a motor in the multi-frequency electrically-tunable antenna, starting the motor at the expected rotating speed of the motor, and obtaining actual rotating speed of the motor according to the Hall sampling value of the motor if the motor does not complete a predetermined target number of rotating turns; and comparing the expected rotating speed of the motor with the actual rotating speed, and adjusting the actual rotating speed ofthe motor according to a comparison result until the motor completes the target rotating turns. The rotating speed of the motor is adjusted in a self-adaptive mode, so that vibration of the motor iseffectively reduced, and the adjusting reliability is improved. According to the invention, the motor rotation adjustment subdivision distance reaches 7.2 degrees, the adjustment precision reaches 0.1degree, accurate gear engagement is realized, the angle adjustment error caused by inertia and a transmission screw gap is reduced, and the technical development requirements of the multi-band fusionelectrically tunable antenna are met.
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 ...
