The present disclosure firstly provides an electric energy collector of a direct current machine room, as shown in fig. 1, the electric energy collector 3 of the direct current machine room can collect a current value and a voltage value of the direct current machine room in real time through a single device.

Therefore, the electric energy collector 3 of the direct current machine room provided by the present disclosure can significantly reduce the monitoring cost of the energy consumption of the direct current machine room, and can reduce the workload of installation thereof.
Specifically, the dc machine room may have a dc cable 1 and a dc cabinet 2, wherein the dc cable 1 may be electrically connected to the dc cabinet 2 to provide current for the dc cabinet 2. The electric energy collector 3 of the direct current machine room can comprise a current collecting module 5 and a voltage collecting and power supplying module 6. The direct current machine room may be a data center machine room, but is not limited thereto.
The current collection module 5 may be connected to the dc cable 1, so as to collect a current value flowing through the dc cable 1 in real time. The current value of the direct current cable 1 is collected in real time through the current collecting module 5, so that a worker can obtain the current in the direct current machine room in real time to judge the energy consumption condition of the direct current machine room.
In one embodiment of the present disclosure, as shown in fig. 2, the current collection module 5 may include a current collection unit 51 and a current analysis control unit.
