Document Type and Number:

WIPO Patent Application WO/2024/109524

Kind Code:

A1

Abstract:

Provided in the present invention are a controller cover opening protection circuit and device, a LiDAR controller and a driving device. The controller cover opening protection circuit comprises a cover opening detection apparatus, a logic operation unit and a controller. A first input end of the logic operation unit is electrically connected to the cover opening detection apparatus and a power supply. An output end of the logic operation unit is electrically connected to an object to be controlled. The controller is electrically connected to a second input end of the logic operation unit. The cover opening detection apparatus is used for, when detecting a cover of the controller is opened, outputting a first level signal, and the logic operation unit is used for outputting, according to the first level signal and a second level signal of the controller, a third level signal used for controlling said object not to work. Therefore, upon opening of the cover of the controller, the present invention automatically controls said object to stop working, thereby ensuring the personal safety of operators, and improving the safety when covers of controllers are being opened.
