Description

Technical Field

[0001] The utility model relates to the technical field of shortwave phased array antennas, in particular to an adaptive synchronous rotation platform. Background Art

[0002] The shortwave phased array antenna is composed of multiple antenna units synthesized through phase control, which places high demands on the relative position relationship between the antenna units. It is necessary to change the relative position relationship between the antenna units in the phased array according to different communication requirements. At the same time, it is also required that the antenna units must ensure synchronous rotation.

[0003] Chinese patent document CN114122723 A discloses a synchronous rotation platform for an array antenna, comprising a circular track with track flat cars evenly distributed circumferentially on the circular track, a support shaft disposed at the central axis of the circular track, a central platform rotatably disposed on the support shaft, and the track flat cars and the central platform connected by a truss arm. While the central platform and the truss arm define the relative positions of the individual track flat cars, while ensuring their synchronous movement, the individual track flat cars cannot change their relative positions according to communication requirements, and thus cannot change the relative positions of the antenna units. Furthermore, the central platform and the truss arm are extremely heavy, occupying intermediate space and requiring high investment costs. Utility Model Content

[0004] The utility model proposes an adaptive synchronous rotation platform, which ensures that each anti-tilt load-bearing platform moves synchronously along the load-bearing track through the cooperation of a position recognition system, position coding and a central controller. At the same time, the central platform and truss arm are omitted, making it easy to adjust the relative position relationship between each anti-tilt load-bearing platform according to communication requirements.

[0005] The technical solution of the present utility model is achieved as follows: an adaptive synchronous rotating platform includes an annular channel, an anti-tilt bearing platform is provided along the circumference of the annular channel, a position identification system is provided on the anti-tilt bearing platform, a position code that cooperates with the position identification system is provided in the annular channel, and the position identification system of each anti-tilt bearing platform is connected to the central controller.

[0006] Furthermore, the position recognition system includes a visual camera and a position controller. The visual camera is used to shoot the position code. The visual camera is connected to the position controller, and the position controller is connected to the central controller. The anti-tilt load-bearing platform is also provided with a position brake and a load-bearing wheel driven by a motor reducer. The position brake and the motor reducer are both connected to the position controller.

[0007] Furthermore, annular anti-tilt walls are provided on both the inner and outer sides of the annular channel, an annular anti-overturning track eaves are provided on the inner side of the anti-tilt walls, and the position code is provided on the inner side of the anti-tilt walls.

[0008] Furthermore, the anti-tilt bearing platform includes a walking platform frame, and anti-tilt wheels and guide wheels are provided on the inner and outer sides of the platform frame. The anti-tilt wheels move along the lower end surface of the anti-tilt track eaves, and the guide wheels move along the inner side surface of the anti-tilt track eaves.

[0009] Furthermore, a bearing track is provided in the annular channel, and the bearing wheels move along the bearing track. Position brakes are provided at both the front and rear ends of the platform frame, and the position brakes are placed on the bearing track.

[0010] Beneficial effects of the utility model:

[0011] The present invention identifies the absolute position of each anti-tilt bearing platform through the coordination of a position identification system and position coding, and centrally controls it through a central controller, thereby ensuring that each anti-tilt bearing platform moves synchronously along the bearing track; at the same time, the central platform and truss arm are eliminated, saving investment costs, so that the diameter of the shortwave phased array antenna is no longer limited by the size of the central platform and the truss arm. The center of the annular channel has no frame occupying the site, and it is also convenient to adjust the relative position relationship between each anti-tilt bearing platform according to communication needs. The anti-tilt bearing platform of the present invention can prevent the antenna from tipping over and enable the bearing wheels to run smoothly along the bearing track through the coordination of anti-tilt wheels, guide wheels, anti-tilt vertical walls and anti-tilt track eaves.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1-3 As shown, the adaptive synchronous rotation platform includes an annular channel 1, a bearing track 2 is arranged in the annular channel 1, annular anti-tilt walls 3 are arranged on the inner and outer sides of the annular channel 1, an annular anti-overturning track eaves 4 is arranged on the inner side of the anti-tilt wall 3, and the bearing track 2, the anti-tilt wall 3 and the anti-overturning track eaves 4 are all arranged concentrically.

[0021] An anti-tilt load-bearing platform 5 is provided along the circumferential direction in the annular channel 1. The anti-tilt load-bearing platform 5 includes a platform frame 6. Load-bearing wheels 7 are installed at the four corners of the lower end of the platform frame 6. The load-bearing wheels 7 on one diagonal line are connected to the motor reducer 8. The load-bearing wheels 7 move along the load-bearing track 2. Position brakes 9 are installed at the front and rear ends of the platform frame 6. The position brakes 9 are placed on the load-bearing track 2.

[0022] Anti-tipping wheels 10 and guide wheels 11 are installed on the inner and outer sides of the platform frame 6. As the platform frame 6 moves along the load-bearing track 2, the anti-tipping wheels 10 move along the lower end surface of the anti-tipping track eave 4, and the guide wheels 11 move along the inner side surface of the anti-tipping track eave 4.

[0023] like Figure 4 As shown, a position identification system is also installed on the anti-tilt bearing platform 5, and a position code 12 that cooperates with the position identification system is provided on the inner side of the anti-tilt vertical wall 3.

The visual camera 13 is an industrial camera, which can be purchased directly on the market. The industrial camera is equipped with an infrared fill light. The industrial camera records the position code 12 in real time, and converts the image into a position signal through the OCR processing board of the industrial camera and transmits it to the position controller 14. The position controller 14 adopts an STM32 microcontroller.

[0024] Position brake 9 and motor reducer 8 are both connected to position controller 14. Position brake 9 and motor reducer 8 are both existing devices.

The position controllers 14 of each anti-tilt load-bearing platform 5 are connected to the central controller via an RS485 communication line. The specific connection method of the RS485 communication line belongs to the existing technology. The position controller 14 transmits the position information to the central controller, which is centrally controlled by the central controller to keep the anti-tilt load-bearing platforms 5 running synchronously. Figure 5 As shown, when the adaptive synchronous rotation platform is used, the high mast tower carrying the antenna is erected on the anti-tilt bearing platform 5.
