[0053] The second signal transmission unit 201 receives the instruction sent by the signal box 10 through the second antenna unit 202 and transmits the instruction to the pitch control paddle central control device 30.

[0054] In the embodiment of the present disclosure, the signal box and the signal relay box are wirelessly connected, and the signal relay box and the pitch control paddle central control device are wired connected, so that the user can stand at a position where the pitch of the pitch control paddle can be observed and send a control instruction through the signal box. In this way, only one person can observe and control at the same time, avoiding the problems of inconvenient communication and operation between two people. Among them, the user generates an instruction through the control panel of the signal box, and then transmits the instruction through the signal transmission unit and antenna of the signal box and the signal relay box, and finally outputs it to the pitch control paddle central control device by the signal relay box, and the pitch control paddle central control device controls the pitch control paddle. The above control process is simple and does not cause repeated operations, saving a lot of time.

[0070] Among them, the indicator light can be a light-emitting diode (LED) indicator light or other types of indicator lights. Among them, when the indicator light is on, it means that the corresponding operation of the button is running, and when the indicator light is off, it means that the corresponding operation of the button has stopped running.
