Specifically, the smart switch 220 refers to a unit that uses a combination and programming of a control board 221 and electronic components to implement control of the circuit smart switch 220. In the present utility model, the control board 221 detects abnormality such as abnormality of software and excessive temperature inside the charging pile 140, thereby realizing self-checking of the state of the charging pile 140. When an abnormality is detected, the control board 221 turns off the double control circuit 200, thereby realizing automatic power-off protection. It should be noted that, the detection of the abnormality of the software by the control board 221, the excessive temperature inside the charging pile 140, etc. are known to those skilled in the art, and the present utility model will not be further described.
