Description

technical field [0001] The invention relates to the technical field of a vehicle-mounted closed-loop DC motor automatic recovery control device and a control method thereof. Background technique [0002] Since the satellite-to-satellite system in China at the present stage adopts the open-loop control principle, the mechanism mainly adopts the transmission structure of the stepping motor, and the antenna recovery mainly adopts manual recovery of the antenna to the mechanical origin while watching the rotation of the antenna. Automatic recovery is also to achieve the purpose of recovering the antenna to the mechanical origin by relying on the CPU memory of the star control system when the star system is not powered on, and due to mechanical errors, the power is suddenly cut off when the antenna is moving, and the stepping motor loses steps, etc. The reason will bring a lot of errors, and it is difficult to make the antenna return to the mechanical origin accurately. There is...

Problems solved by technology

[0002] Since the satellite-to-satellite system in China at the present stage adopts the open-loop control principle, the mechanism mainly adopts the transmission structure of the stepping motor, and the antenna recovery mainly adopts manual recovery of the antenna to the mechanical origin while watching the rotation of the antenna. Automatic recovery is also to achieve the purpose of recovering the antenna to the mechanical origin by relying on the CPU memory of the star control system when the star system is not powered on, and due to mechanical errors, the power is suddenly cut off when the antenna is moving and the stepping motor loses steps, etc. The reason will bring a lot of errors, it is difficult to make the antenna return to the mechanical origin accurately

There is also a sudden power failure when the antenna is looking for stars. You have to recover the antenna first. You don’t know the location of the antenna. The numbness of automatic recovery will hit the equipment around the antenna.

Therefore, it is difficult for the open-loop alignment system to accurately know whether the antenna is recovered to the mechanical origin, which brings inconvenience to the operator to control the recovery of the antenna and difficulty in maintaining the equipment.
