However, if the sweeping parts are stuck by objects in the process of sweeping, it will easily lead to equipment failure, if people's fingers are accidentally stuck, it will cause human injury. Therefore, the photoelectric switch is often used as a safety detection and protection device to judge whether the detection operation is in place or prevent the hand from being pinched. In the prior art, there is a problem of false detection when using the photoelectric switch to prevent the hand from being pinched. Analyzes the existing problems and give an effective solution and optimization scheme.
