[0045] The input end of the blocking component 100 is electrically connected to the output end of the regulating module 400. Driven by the regulating module 400, the blocking component 100 can move forward and backward according to a set movement trajectory.

[0046] The input of the sensing device 200 is electrically connected to the output of the control module 400, and the output of the sensing device 200 is electrically connected to the input of the load component 300. Driven by the control module 400, the sensing device 200 can detect the blocking component 100 and output a pulse signal to the load component 300.

[0047] The sensing device 200 can be arranged on the same horizontal line as the blocking component 100, so that the sensing device 200 can detect the blocking component 100. The sensing device 200 can detect the blocking component 100, thereby obtaining a distance value between the sensing device 200 and the blocking component 100.
