The invention discloses a high-voltage electricity taking safety control device which comprises a PLC upper-mounted controller and a VCD vehicle control unit, the PLC upper-mounted controller is electrically connected with the VCD vehicle control unit through a CAN bus and performs data interaction with the VCD vehicle control unit, the VCD vehicle control unit is electrically connected with a PDU high-voltage box, and the PDU high-voltage box is electrically connected with the PLC upper-mounted controller. The PLC top-mounted controller is connected with a first electric appliance and a second electric appliance through a CAN bus. And the Hall sensor is connected to the high-voltage wire harness. A loading system and a chassis system are integrated into one control system through a CAN bus, a Hall sensor is additionally arranged on a high-voltage wire harness, and the PLC loading controller, the VCD vehicle control unit, the PDU high-voltage box and the Hall sensor are used in cooperation. Potential safety hazards caused by electric leakage and short circuit are prevented by means of pre-discharge request, pre-discharge, pre-discharge current detection, work discharge request, real-time voltage and current detection and automatic power failure judgment, so that the probability of occurrence of safety accidents is reduced.
