Background
With the vigorous development of the satellite field in China, the application of a satellite terminal station is not limited to be fixed on the ground any more, and gradually develops towards the aspect of a mobile carrier, and a satellite antenna must be ensured to be always aligned to a satellite by using a communication-in-motion antenna on the mobile carrier. Because the mobile carrier can generate displacement in the driving process, the satellite antenna needs to adjust the direction in time, the direction adjustment needs to be limited within a certain range, otherwise, the unlimited rotation can cause the cables in the antenna to be wound together, so that the cables are damaged, and the mobile satellite needs to arrange a limiting mechanism in the azimuth rotating device to limit the rotating range of the mobile satellite in the azimuth direction.
A limiting mechanism in an existing satellite antenna azimuth rotating device is a deflector rod rotating device commonly used, and due to the fact that a certain angle exists in occupied space of a limiting column, a continuous working angle is generally smaller than 720 degrees. During initial power-on, the antenna can repeatedly search within the range of 150-530 degrees from the limit zero until the antenna is aligned with the satellite, and at the moment, the minimum value of an included angle (namely a reserved buffer zone) between the azimuth angle of the antenna and the limit column is 150 degrees. If the mobile carrier just turns around rapidly and reverses 180 degrees at the moment, a limiting device can be triggered, the phenomenon of satellite loss occurs, then the antenna starts to search for the satellite again, and the non-signal state of a period of time can occur, so that the customer experience is influenced.
In addition, the rotation of each shaft of the communication-in-motion antenna also involves the problem of the winding of a transmission cable, the existing cable threading mode mainly comprises two modes of conductive slip rings or direct cable threading, and the conductive slip rings are high in manufacturing process requirement and manufacturing cost and cannot be popularized; and the mode of directly penetrating the cable is adopted, so that the risk of cable twisting is high.
