The position rotation and pitching rotation limit detection adopts a limit switch, namely a non-contact type induction switch (Omron E2EX5ME1, NPN type output, normally open type and 24V power supply), when an azimuth shaft or a pitching shaft rotates into a limit area, a metal block enters an induction area of the induction switch, the output of the induction switch is in a closed state and conducted to the ground, and a main control board reads the state through a photoelectric isolation interface board (PM540) to perform parking operation in the direction.
The locking and unlocking detection device also adopts a limit switch, namely a non-contact inductive switch (Omron E2EX5ME1, NPN type output, normal open type, 24V power supply). When the system is powered on and works, the lock pin is in a locking state, the motor driver is in a power-off state, the unlocking is completed through manual operation, and after the lock pin is unlocked in place, the corresponding inductive switch is induced, the closed state is output, and the motor driver is powered on. When the system is finished, the antenna is guided to a storage position (azimuth and pitching zero position), the locking action of the lock pin is completed by manual operation, and when the lock pin is locked in place, the sensing device sends out a closed state, and the driver is powered off.
The control system adopts a computer closed-loop control scheme, so that a designer can more flexibly design a loop and adopt different mathematical models, and after a hardware circuit is designed, targeted compensation and modification (continuous improvement process is carried out by writing software, adding a new compensation algorithm, a filtering algorithm and the like) can be carried out at any time aiming at problems found later without modifying a hardware circuit part, and the advantage is incomparable to simulation control design.
And the antenna controller, the antenna driver, the limit switch and the motor exchange data information through a CAN bus. The antenna controller communicates with the monitoring computer through a network interface, receives control and query instructions of the monitoring computer, executes specified actions and reports antenna attitude information.
The monitoring computer issues instructions and exchanges data information with the PC104 industrial personal computer of the ACU through the RS232 interface. When the antenna works, the main control board gives a D/A signal to a speed input port of the servo driver, and the motor driver controls the motor to rotate to drive the reducer to output force so as to change the axial direction, thereby changing the direction of the antenna. The encoder is connected with the shaft end, senses the change of the shaft angle and uploads the data to the PC104 industrial personal computer. The industrial personal computer reads various data (including shaft angles, limit states, locking states, driver running states, upper computer commands, local manual operation commands and the like) and sends various control instructions and uploads the data in real time, so that the functions of total control and management are achieved.
