The control principle is as follows:
in the lifting mode, a key is started to lift the locking button, and the servo control box 2 realizes the control of starting, accelerating, uniform speed, decelerating and stopping of the motor by collecting in-place sensor signals at different positions. Two in-place sensors 23 are respectively arranged at the upper and lower positions, and are sequentially marked as 23-a, 23-b, 23-c and 23-d from top to bottom, the clothes control box detects that the sensing point 24 is between the in-place sensors 23-c and 23-d, the motor is controlled to accelerate, and the lifting rod 1 is accelerated to rise; after the servo control box 2 detects that the sensing point 24 is in-place at the sensor 23-c, the motor 5 is controlled to rotate at a constant speed, and the lifting rod 1 is lifted at a constant speed; after the servo control box 2 detects that the sensing point 24 is in-place by the sensor 23-b, the motor 5 is controlled to be decelerated, and the lifting rod A is controlled to be decelerated; after the servo control box B detects that the sensing point a is in-place at the sensor 23-a, the control motor 5 stops, the lifting cylinder mounting seat 11 and the guide sleeve 13 are limited at the moment, the plug pin 30 faces the locking hole on the lifting cylinder mounting seat 11, and the servo control box 2 controls the electric push rod 26 to insert the plug pin 30 into the locking hole, so that the lifting rod 1 is locked. Generally, due to processing and assembly errors of equipment, when the servo control box 2 detects that the sensing point 24 is in place and the sensor 23-a is not completely limited, the servo control box 2 controls the motor 5 to slowly move, the lifting rod 1 continues to ascend, when the lifting barrel mounting seat 11 and the guide sleeve 13 are completely limited, the control current of the motor 5 is increased, the torque limiter 7 limits the further increase of the control current through slipping, the servo control box 2 controls the electric push rod 26 to insert the bolt 30 into the locking hole, and the servo control box 2 judges whether the locking mechanism is locked in place or not by collecting a locking in-place signal on the electric push rod 26, and controls the electric push rod 26 to stop after the locking is in place; finally, the servo control box 2 controls the motor 5 to stop. The relative position relation between the bolt 30 and the locking hole is ensured by the mechanical limit of the lifting rod 1, and the control precision of the device on the control system is not high; after the lifting rod 1 is limited, the system can be protected through slipping of the moment limiter 7, the overload protection of the motor is designed by the servo controller, and the overload current is larger than the current required by slipping of the moment limiter 7, so that the mechanical and electrical double protection of the device is realized;
when in a descending mode, a one-key unlocking descending button is started, after the servo control box controls the locking mechanism to unlock, the starting motor 5 is started and runs in an accelerating mode, and the lifting rod 1 starts to descend; after the servo control box 2 detects that the sensing point 24 is in-place at the sensor 23-a, the motor 5 is controlled to rotate at a constant speed, and the lifting rod 1 descends at a constant speed; after the servo control box 2 detects that the sensing point 24 is in-place by the sensor 23-c, the motor 5 is controlled to be decelerated, and the lifting rod 1 is decelerated to fall; after the servo control box 2 detects that the sensing point 24 is in-place by the sensor 23-a, the motor 5 is controlled to stop, at the moment, the antenna mounting seat 12 and the limiting sleeve 22 are mechanically limited, the lifting rod 1 stops moving, and the lifting rod is closed. Generally, the height of the lifting rod 1 is slightly lowered due to unstable load borne by the antenna, the gap between the bolt 30 and the locking hole is eliminated, the friction force is increased when the locking mechanism is unlocked, the locking mechanism cannot be unlocked when the friction force is serious, under control, after a one-key unlocking button is started and a descending button is started, the motor 5 is slowly rotated to control the lifting rod 1 to be lifted to a mechanical limit, the servo control box 2 controls the locking mechanism to be unlocked and controls the motor to be stopped, and after the locking mechanism is unlocked, the servo control box 2 controls the motor 5 to be reversely started and accelerated, and the lifting rod 1 starts to fall; due to the processing and assembly errors, when the servo control box 2 detects that the sensing point 24 is in the in-place sensor 23-a, the lifting rod 1 is not completely and mechanically limited, the motor 5 continues to slowly move, and when the lifting rod 1 is completely and mechanically limited, the moment limiter 7 protects the lifting rod 1 through slipping, and then the servo control box 2 controls the motor 5 to stop, so that the lifting rod 1 is closed.
