As shown in fig. 7, the energy saving method provided in the embodiment of the present invention includes:

s701, the energy saving device 100 acquires current state information.

And the current state information is used for representing whether the expansion unit equipment is in the energy-saving working state currently or not.

Optionally, after acquiring the current state information, the energy saving device 100 may also report the acquired current state information to the host unit device 200.

S702, the energy saving device 100 obtains the target value.

The target value is the ratio of the number of target time domain points in the time slot to the number of time domain points in the time slot, and the target time domain points are time domain points with the instantaneous power larger than a first threshold value.

Alternatively, the target value may be a ratio of the number (or length) of OFDMA symbols having power in the slot to the number (or length) of OFDMA symbols in the slot.

Specifically, the energy saving device 100 first obtains the number of time domain points and power information in the time slot. Then, the energy saving device 100 determines the number of target time domain points in the time slot according to the power information. Finally, the energy saving device 100 determines a target value according to the number of time domain points in the time slot and the number of time domain points with power in the time slot. Wherein the power information comprises an instantaneous power for each time domain point in the time slot.

In a possible implementation manner, the target value may also be the output power of the ethernet port PICO terminal of the expansion unit device.

In the case where the target value is the output power of the ethernet port PICO terminal of the expansion unit device, the energy saving device 100 may first obtain the output voltage of the ethernet port PICO terminal of the expansion unit device and the output current of the ethernet port PICO terminal of the expansion unit device. And then determining the output power of the Ethernet power port PICO end through the output voltage of the Ethernet power port PICO end of the expansion unit equipment and the output current of the Ethernet power port PICO end of the expansion unit equipment. For example, the output power of the ethernet port PICO terminal is determined to be the output voltage of the ethernet port PICO terminal of the expansion unit device × the output current of the ethernet port PICO terminal of the expansion unit device.

Optionally, after obtaining the target value, the energy saving device 100 may also report the obtained target value to the host unit device 200.

And S703, the energy saving device 100 determines that the expansion unit device enters the energy saving working state under the condition that the target value is smaller than the second threshold value and the expansion unit device is not in the energy saving working state currently.

Specifically, the energy saving device 100 determines that the expansion unit device turns off the clock of the IQ data processing module and stops supplying power to the FPGA when the target value is smaller than the second threshold and the expansion unit device is not currently in the energy saving operating state.

The expansion unit device can turn off the clock CLK _ IQ of the IQ processing data module by controlling the clock control switch CLK _ EN to turn off the IQ processing data module, and control a Power Sourcing Equipment (PSE) chip to stop supplying power to the FPGA through a control interface (for example, an I2C interface).

It can be understood that the target value is smaller than the second threshold and the expansion unit device is not currently in the energy saving operating state, which indicates that the expansion unit device currently has less traffic and the expansion unit device is not currently in the energy saving operating state. Because the current traffic of the expansion unit equipment is less, the expansion unit equipment can be switched from the non-energy-saving working state to the energy-saving working state in this case, so that the energy consumption of the expansion unit equipment and the digitization room is reduced.

It is worth mentioning that, in the FPGA inside the extension unit device, 70% of the FPGA resources are consumed by the time domain IQ data processing module and the frequency domain IQ data processing module, and the generated power consumption accounts for about 60% of the FPGA power consumption. Therefore, the power consumption of the FPGA of the extension unit equipment can be reduced by about 60% by turning off the IQ data processing module. In addition, the closure of the IQ data processing module does not affect the OAM data processing module of the extension unit device, i.e., the extension unit device can normally process OAM data when the IQ data processing module is closed.

From S701 to S703, it can be seen that, in the embodiment of the present invention, when the expansion unit device is not currently in the energy saving operating state and the current traffic of the expansion unit device is small (that is, the target value is smaller than the second threshold), the expansion unit device enters the energy saving operating state, so as to reduce energy consumption of the expansion unit device. Because the expansion unit equipment is an important component of the digital room, the embodiment of the invention can also reduce the energy consumption of the digital room by reducing the energy consumption of the expansion unit equipment, thereby solving the problem of how to reduce the energy consumption of the digital room.

Referring to fig. 7, as shown in fig. 8, the energy saving method provided in the embodiment of the present invention may further include:

s704, the energy saving device 100 determines that the expansion unit device enters the non-energy saving operating state when the target value is greater than the second threshold and the expansion unit device is currently in the energy saving operating state.

Specifically, the energy saving device 100 determines that the expansion unit device starts a clock of the IQ data processing module and starts to supply power to the FPGA when the target value is greater than the second threshold and the expansion unit device is currently in the energy saving operating state.

The expansion unit device can enable the IQ data processing module to be started by controlling the clock control switch CLK _ EN to start the clock CLK _ IQ of the IQ data processing module, and controls the PSE chip to start (recover) to supply power to the FPGA through the control interface.

It can be understood that the target value is greater than the second threshold and the expansion unit device is currently in the energy-saving operating state, which indicates that the expansion unit device has a large current traffic and the expansion unit device is currently in the energy-saving operating state. Because the current traffic of the expansion unit device is large, the expansion unit device needs to be changed from a non-energy-saving working state to an energy-saving working state to process the service in time.

The energy saving device 100 determines that the expansion unit device remains in the energy saving operating state when the target value is smaller than the second threshold value and the expansion unit device is currently in the energy saving operating state.

The energy saving device 100 determines that the expansion unit device remains in the non-energy saving operating state when the target value is greater than the second threshold value and the expansion unit device is not currently in the energy saving operating state.
