When the mains supply is normal, the uninterruptible power supply stabilizes the voltage of the mains supply and supplies the regulated voltage to a load for use, and meanwhile, the uninterruptible power supply also charges an internal battery; when the commercial power is interrupted, the uninterruptible power supply immediately supplies the electric energy of the built-in battery to the circuit by an inversion conversion method, so that the circuit keeps working normally and is protected from being damaged. When the charging bow is in a charging state and the commercial alternating current power supply is accidentally powered off, the uninterruptible power supply can continue to supply power to the circuit, the control circuit controls the driving circuit to lift the charging bow, normal operation of a vehicle cannot be affected, meanwhile, the situation that the vehicle or the charging bow is damaged due to forced driving away of the vehicle and potential dangerous accidents such as falling of the charging bow damage fittings and injury to pedestrians can be avoided.
Referring to fig. 2 specifically, the charging bow breaking and lifting control device comprises a driving circuit and a control circuit, wherein the driving circuit is directly powered by a three-phase four-wire 380V alternating current power supply of a commercial power, and the control circuit is powered by a direct current power supply. An uninterruptible power supply is connected between the 380V alternating current power supply of the mains supply and the driving circuit, and the uninterruptible power supply is 380V/20KVA according to the supply voltage of the mains supply. The driving circuit comprises a servo motor driver and a servo motor, wherein the output end of the servo motor driver is electrically connected with the servo motor, the servo motor driver is used as a controller of the servo motor and used for driving the servo motor to work, and the servo motor is connected with a charging bow lifting mechanism (not shown in the figure) so as to drive the charging bow to lift; the control circuit includes PLC and charging bow control panel, PLC and servo motor driver electric connection for send the instruction of rising the bow or falling the bow to servo motor driver, charging bow control panel and PLC, charging bow are connected, and charging bow control panel is used for detecting the charge state of charging the bow and feeds back the signal that detects to PLC.
