Specifically, the target voltage output circuit 100, the target voltage sampling circuit 200, and the infrared emitting circuit 300 are serially connected, and the target voltage output circuit 100 is mainly used for adjusting the voltage output from the target output circuit and then input to the target voltage sampling circuit 200, wherein one end of the target voltage output circuit 100 is a positive electrode, which is VCC shown in fig. 1, that is, the total voltage input of the obstacle detecting circuit 1 in this embodiment. On the side close to the target voltage sampling circuit 200, one end of the target voltage output circuit 100 is electrically connected to the target input voltage 700, the magnitude of the target input voltage 700 is the magnitude of the voltage actually input to the target voltage sampling circuit 200, and the magnitude of the target input voltage 700 is controlled by the target voltage control signal sent by the target voltage controller 400, wherein specifically, for example, the total voltage magnitude of VCC is 220V, the input target voltage control signal has data information of 80% on and 20% off, and then the target input voltage 700 in the target voltage output circuit 100 is 176V at this time, that is, the magnitude of the target input voltage 700 is changed by changing the target voltage control signal.
