[0006] 3. Since the braking current or voltage must not exceed 30% of the rated current or voltage (otherwise the temperature rise of the AC asynchronous motor will increase and affect its service life), the braking torque cannot reach the rated working torque
[0007] In view of the above limitations, it is impossible to ensure that the antenna position is locked and can maintain this attitude safely and reliably for a long time, so it is necessary to provide a new measure

Embodiment Construction
[0022] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0023] The invention uses software to control the AC servo motor to automatically run to the locked position, and at the same time controls the "enable" signal of the AC servo drive to be valid all the time, so that the attitude of the antenna remains unaffected by other disturbances for a long time. The principle block diagram is in figure 1 shown in .
[0024] see figure 1 , the working principle of the embodiment of the present invention is that after the central control unit receives the "position lock" command from the remote control terminal, it compares the position to be locked with the real position fed back by the "position feedback unit", uses the comparison result as an error signa...

The invention discloses an antenna position locking and posture long-time keeping method, which uses an alternating current servo driving system to drive an antenna, and the alternating current servodriving system comprises a central control unit, an alternating current servo driver, an alternating current servo motor, a speed reducing mechanism, an antenna position feedback unit and a control terminal. The control terminal is used for providing a position locking command for the central control unit, and the central control unit controls the alternating current servo motor to rotate throughthe alternating current servo driver and judges whether the antenna rotates in place or not according to the position information fed back by the antenna position feedback unit. And the speed output of the alternating-current servo driver is controlled to be zero after the alternating-current servo motor rotates in place, and the enabling control end of the alternating-current servo motor is kepteffective. The method can ensure that the antenna position is locked and the posture is safely and reliably kept for a long time, and equipment does not need to be modified or added.
Description
technical field [0001] The invention relates to a method for antenna position locking and long-term posture maintenance for special equipment, so that the antenna can maintain this posture for a long time after the position is locked, and avoid the unevenness of the antenna seat vehicle (ground), the offset of the center of gravity of the antenna, and the natural wind force. The failure of antenna position locking caused by factors such as antennae affects the data collection of special equipment. Background technique [0002] When a special equipment searches for a target signal by the antenna, it needs to keep this posture at the target position for a long time, so that the special equipment can collect, analyze and store the attributes and types of the target into the database. [0003] The Chinese patent document CN201810387459.X provides a measure to achieve anti-disturbance (position locking and attitude maintenance) by applying DC braking to the AC asynchronous motor ...
