The test principle of each mechanism is explained below.
1. Pitch symmetry mechanism control test
The test device omits a PLC control module and related software for the synchronous symmetrical mechanism, and makes full use of a speed closed-loop system of the alternating current servo by modifying internal parameters of the alternating current servo driver so as to keep the left and right sides of the symmetrical mechanism to synchronously move.
As shown in fig. 1, the ac servo driver and the ac servo motor form a speed closed-loop control system (the testing device also fully utilizes the speed closed-loop control of the ac servo motor), the power output of the ac servo driver drives the ac servo motor to rotate, and meanwhile, the ac servo motor feeds back the actual rotation speed to the ac servo driver through the encoder, so that the ac servo driver calculates the current rotation speed of the motor to realize the speed closed-loop control, and the rotation speed of the ac servo motor is stabilized at the set rotation speed. The parameters of the double alternating current servo driver are set to be completely consistent (same acceleration and deceleration time and same movement speed), so that the two alternating current servo motors are guaranteed to be strictly synchronous in rotation speed, and the left mechanism and the right mechanism of the traction pitching symmetrical mechanism pitch up or pitch down synchronously.
In one embodiment, the parameters to be set when the dual ac servo driver controlling the pitch symmetry mechanism is applied to the test device are: (1) The panel displays parameter items, wherein the test device is set to monitor torque; (2) Digital speed parameter item, wherein digital speed commands 1 and 2 of the testing device are respectively set to +1000 and-1000; (3) Acceleration time parameter item, wherein the test device is set to 2 seconds; and (4) a deceleration time parameter term, wherein the test apparatus is set to 2 seconds.
The double alternating current servo driver can run at a set speed with the same acceleration and deceleration time, so that the synchronous traction pitching symmetrical mechanism of the two alternating current servo motors is guaranteed to pitch upwards or pitch downwards, and the stress of the left and right mechanisms in the motion process is displayed on a self-contained panel of the alternating current servo driver.
In one embodiment, the control ports of the dual ac servo driver controlling the pitch symmetry mechanism are provided with "enable (SVON)" and "digital speed" selection control bits (SPD 1, SPD 2), wherein the enable control bits are used for controlling the ac driver to work or stand by; the digital speed selection control bits are used by the SPD1, SPD2 in combination for selecting a speed set, an ac servo driver control port diagram is shown in fig. 5.
The servo enabling switch of the test device is connected with an SVON port, and two alternating current drivers must be controlled to work or stand by at the same time; the antenna upward-tilting and antenna downward-tilting switches are respectively connected with the ports of the two alternating current drivers (SPD 1) and the SPD 2) and are used for selecting the digital speed to control the two alternating current drivers to drive the two alternating current servo motors to forward or backward pull the pitching symmetrical mechanism according to the same speed so as to realize the upward-tilting or downward-tilting of the antenna. The combination of the digital speed selection control bits SPD1, SPD2 determines the speed setting, the ac servo driver speed setting selection is shown in fig. 6.
The antenna up and down switches of the test device are respectively connected with the ports of SPD1 and SPD2, and the given examples of optional speeds are as follows:
when the antenna upward turning switch is turned on, a digital speed command 1 (which is set to be +1000) is selected, and the alternating current servo motor rotates forward according to the set digital speed, and the antenna upward turning is realized by the traction pitching symmetrical mechanism.
When the antenna dip switch is turned on, a digital speed command 2 (set to be-1000) is selected, the alternating current servo motor is reversed according to the set digital speed, and the pitching symmetrical mechanism is pulled to realize the antenna dip.
When both the antenna tilt up and antenna tilt down switches are on, a digital speed command 3 (set to 0) is selected and the ac servo motor stalls.
When the two switches of the antenna upward and downward are connected and turned off, an analog speed command is selected (the test device has no analog speed given), and the alternating current servo motor stops rotating.
The torque balance degree is an important index for testing whether the pitching symmetry mechanism is qualified in installation and debugging, the torque of the alternating current servo motor in the upward or downward movement process of the pitching symmetry mechanism is displayed on a display screen of an alternating current servo driver in real time, a direct basis is provided for installation, debugging and inspection personnel, and meanwhile, the device is very convenient for testing the position synchronism of the pitching symmetry mechanism in the movement process and whether the phenomenon of clamping or blocking exists.

The control principle is shown in fig. 7.
The corresponding functions of the testing device when the turntable locking and the turntable unlocking are connected are as follows:
the turntable locking switch is connected, and the AC asynchronous motor of the turntable locking mechanism is controlled to forward rotate to pull the turntable locking mechanism to realize turntable bolts.
The rotary table unlocking switch is connected, and the rotary table locking mechanism is pulled by the reverse rotation of the alternating current asynchronous motor of the rotary table locking mechanism to realize the pin pulling of the rotary table.
