In the utility model, whether the current collector 4 is communicated with the mobile equipment 5 is detected by the detection unit 3, when the current collector 4 is communicated with the mobile equipment 5, the mobile equipment 5 is positioned on the section of the sliding contact line 1, and the detection unit 3 controls the power supply control unit 2 to be conducted so as to supply power to the corresponding sliding contact line 1; the detection units 3 corresponding to the other sliding contact lines 1 do not detect the communication between the current collector 4 and the mobile equipment 5, which means that the mobile equipment 5 is not positioned on the sliding contact line 1, and the power supply control unit 2 is not conducted, so that all the other sliding contact lines 1 are not electrified. Therefore, the electric energy loss of the trolley wire 1 is effectively reduced, and the efficiency is higher.
When the mobile device 5 spans from one segment of the trolley line 1 to another segment of the trolley line 1, the current collector 4 is not in contact with the trolley line 1 due to a gap between each segment of the trolley line 1, and the current collector 4 cannot take electricity from the trolley line 1, which may cause the mobile device 5 to be powered off.
In some embodiments, as shown in fig. 1, the current collector 4 is a double ended current collector for power engagement as the mobile device 5 spans two segments of the trolley line 1. The double-headed current collector has two contact heads, when the mobile device 5 spans the two-end trolley wires 1, when the previous contact head does not slide off the previous section of trolley wires 1, the next contact head slides onto the next section of trolley wires 1, so that the mobile device 5 cannot be powered off when the mobile device spans the two-end trolley wires 1.
