The utility model discloses an indicator automatic detection bench high-voltage safety protection control system. The system comprises an infrared alarm subsystem and a door lock protection subsystem. The infrared alarm subsystem comprises an infrared transceiver device for detecting whether a man or an object approaches to a detection bench, and a sound-light alarm circuit for giving an alarm when the man or the object approaches to the set distance. The door lock protection subsystem comprises a door lock sensing device for detecting whether a cabinet door lock of the detection bench is locked well, and a starting control circuit for enabling the detection bench not to be started by a starting button when the cabinet door fails to be locked well. An infrared alarm circuit is arranged in front of the indicator automatic detection bench, so that an alarm is given when the detection bench works and the man or the object is N m away from the detection bench; and a protection circuit associated with the door lock of the detection bench is provided, so that when the door lock of the detection bench fails to be locked, even though the confirmation button is pressed down, the detection bench still does not work. The system alarms first, and then, cuts power off, and thus the test is really safe and efficient.
