Fig. 1 is a schematic diagram of a main part of an antenna adjustment system according to an embodiment of the present invention.
As shown in fig. 1, an antenna adjustment system 100 according to an embodiment of the present invention may include a signal receiving portion 101, a control portion 102, and an adjustment portion 103.
Specifically, the signal receiving unit 101 is connected to the control unit 102, and receives a signal acquired by the antenna 200 and transmits the received antenna acquisition signal to the control unit 102. The control unit 102 is connected to the adjusting unit 103, and is configured to receive the antenna collecting signal sent by the signal receiving unit 101, detect the signal strength of the antenna collecting signal, and send the height adjusting signal to the adjusting unit 103 according to the signal strength and a preset policy. In a specific application, the connection among the signal receiving unit 101, the control unit 102, and the adjusting unit 103 may be a wired connection or a wireless connection.
The adjusting unit 103 is fixedly connected to the antenna 200, and adjusts the height of the antenna based on the height adjusting signal after receiving the height adjusting signal transmitted from the control unit 102. The adjustment of the height of the antenna may be raising, lowering or stopping the antenna, wherein the stopping means reaching a standstill in a moving state. The control unit 102 may be a control unit with a main control CPU as a core, the antenna 200 may be an antenna with various frequency bands and various functions, such as a GPS antenna, which may be raised, lowered or stopped by the operation of the adjusting unit 103, and the signal receiving unit 101 may be a GPS board card matched with the GPS antenna.
In practical application, the specific process of the control part 102 adjusting the height of the antenna according to the strength of the signal collected by the antenna and the preset strategy is as follows:
when detecting that the intensity of the antenna acquisition signal is not less than the preset threshold value or the intensity of the antenna acquisition signal is at a higher level, the control part 102 does not send the height adjustment signal and the antenna remains stationary. Preferably, the signal strength may be preset to a plurality of levels, such as A, B, C, D, which respectively indicate that the signal strength is very high, the signal strength is poor, and the signal strength is very poor, wherein A, B is the higher level and C, D is the lower level.
When detecting that the intensity of the antenna collection signal is smaller than the preset threshold value or the intensity of the antenna collection signal is at a lower level, the control section 102 sends a height adjustment signal to the adjustment section 103 so as to control the antenna 200 to rise or fall to improve the signal intensity. The height adjustment signal may be a rising signal for controlling the antenna 200 to rise, a falling signal for controlling the antenna 200 to fall, or a stop signal for stopping the antenna 200.
In a specific application scenario, when it is detected that the antenna acquisition signal is smaller than a preset threshold or is at a lower level, the control unit 102 first sends a rising signal to the adjustment unit 103 to raise the antenna 200. In this process, the signal receiving portion 101 receives the antenna collecting signal in real time, and sends the antenna collecting signal to the control portion 102, and if the control portion 102 detects that the intensity of the antenna collecting signal is still smaller than the preset threshold or at a lower level, the control portion continues to send the rising signal to raise the antenna 200 until the intensity of the antenna collecting signal received by the signal receiving portion 101 is not smaller than the preset threshold or at a higher level. When the intensity of the signal collected by the antenna is not less than the preset threshold value or is at a higher level, the control part 102 sends a stop signal to the adjusting part 103 to stop the antenna 200 from moving, and the antenna height adjustment is finished.
In the embodiment of the present invention, in the process of controlling the antenna to rise, if the intensity of the antenna collecting signal is detected to be decreased, the control unit 102 sends a descending signal to the adjusting unit 103 to descend the antenna 200. In the process of descending the antenna 200, the signal receiving part 101 receives an antenna collecting signal in real time and sends the antenna collecting signal to the control part 102, and if the control part 102 detects that the antenna collecting signal is smaller than a preset threshold value or is in a lower level, the control part continues to send a descending signal to descend the antenna 200 until the antenna collecting signal received by the signal receiving part 101 is not smaller than the preset threshold value or is in a higher level. When the intensity of the signal collected by the antenna is not less than the preset threshold value or is at a higher level, the control part 102 sends a stop signal to the adjusting part 103 to stop the antenna 200 from moving, and the antenna height adjustment is finished.
As a preferable aspect, the adjusting part 103 may include: a drive module 111, a power module 112, and a transmission module 113. The driving module 111 is connected to the control unit 102, and is configured to receive the height adjustment signal sent by the control unit 102 and drive the power module 112 according to the height adjustment signal, and the transmission module 113 is configured to transmit power between the power module 112 and the antenna 200. Illustratively, the power module 112 may be an electric motor and the drive module 111 may be a motor driver.

Wherein, the worm is connected with the output end of the power module 112, and the worm is meshed with the worm wheel nut. The outer surface of the lifting rod is provided with threads which are in threaded connection with the worm gear nut and can ascend or descend along the axis of the worm gear nut, and the top end of the lifting rod is fixedly connected with the antenna 200.
In the process that the control part 102 controls the antenna to ascend or descend, the control part 102 sends an ascending signal or a descending signal to the driving module 111, the driving module 111 drives the power module 112 based on the ascending signal or the descending signal, the power module 112 pushes the worm to rotate so as to enable the worm wheel nut to rotate, the worm wheel nut rotates to drive the lifting rod to ascend and descend, and finally the antenna 200 is lifted and descended. In the process that the control part 102 controls the antenna 200 to stop, the control part 102 sends a stop signal to the driving module 111, the driving module 111 brakes the power module 112 based on the stop signal, and the power module 112 stops the antenna 200 through the transmission of the worm, the worm gear nut and the lifting rod.
In an embodiment of the present invention, the antenna connected to the antenna adjusting system is a height-adjustable antenna. Fig. 2 and 3 show schematic diagrams of height variations of the height adjustable antenna.
