Referring to fig. 2, the pico-base station according to an embodiment of the present disclosure includes a baseband unit, a forwarding gateway, and a radio frequency unit, where the baseband unit may be connected to multiple forwarding gateways, each forwarding gateway may be connected to multiple radio frequency units, and the radio frequency unit is connected to an interface of the forwarding gateway through a remote cable.

In the pico-base station, the forwarding gateway detects the current output by each interface, and monitors the power consumption of the radio frequency unit connected with the interface according to the current output by the interface.

The plurality of forward-transmitting gateways can be connected with the baseband unit in a grading way, wherein the forward-transmitting gateway directly connected with the baseband unit is a primary forward-transmitting gateway, the forward-transmitting gateway connected with the primary forward-transmitting gateway is a secondary forward-transmitting gateway, the forward-transmitting gateway connected with the secondary forward-transmitting gateway is a tertiary forward-transmitting gateway, and the like.

Taking the power module output-48V of the forward gateway as an example, the electric energy output through the interface of the forward gateway not only enables the radio frequency unit to work, but also partially loses on the remote cable. The power supply of the forwarding gateway supports at least 200m of remote, and the equivalent resistance of the remote cable is larger as the remote cable is longer.

The resistance of a 1.0 square millimeter multi-core copper conductor at 20 degrees celsius is 19.5 Ω/km, according to the relevant requirements. Then, in the case of 200m zoom-out, the internal resistance of the plus and minus two cables can be roughly estimated to be 7.8 Ω, which is a total of 400m copper wires. Taking the maximum power consumption of the rf unit as an example of 50W, the current can be roughly calculated to be 50W/48v =1.042a, and the loss of the copper wire is about 1.042a × 7.8 Ω =8.5W.

From the above calculation, the loss of the copper wire is about 17% of the power consumption of the radio frequency unit. Therefore, when the power consumption is reported by the radio frequency unit, even if the power consumption is very accurate, due to the lack of the loss of the remote cable, the power consumption of the base station is actually counted to have an error of 17%. In the embodiment of the disclosure, the output current of the interface of the forwarding gateway is detected, and then the output power P of the interface is obtained according to P = UI, where U is the voltage of the interface, the voltage output by the power supply of the forwarding gateway is adopted, and I is the current of the interface, and the current is obtained by the current detection unit. The embodiment of the disclosure takes the interface output power as the power consumption of the radio frequency unit, considers the loss of the remote cable, and has more accurate result.

The method disclosed by the invention considers the loss of the remote cable, and the result is more accurate.

In one embodiment, the obtaining the power output by each interface according to the output current and the output voltage of the power supply of the forwarding gateway includes: performing analog-to-digital conversion on the output current to obtain a digital signal of the output current; obtaining an output current value according to the digital signal of the output current; and obtaining power according to the output current value and the output voltage.
