Description

The present invention claims to be submitted to the Chinese Patent Office on June 26, 2012, and the application number is 201210213365. 3, the Chinese patent application entitled "A Base Station Equipment Energy Saving Method and Apparatus" Priority is hereby incorporated by reference in its entirety.

TECHNICAL FIELD The present invention relates to the field of communications technologies, and more particularly to an energy saving method and apparatus for a base station device.

BACKGROUND OF THE INVENTION With the rapid development of communication technologies, the power consumption of baseband boards is also increasing. Taking BBU (Base Band Unit) as an example, the power consumption of baseband boards is more than 20 watts. Breaking through the current 80 watts and approaching the development trend of 100 watts. In addition, SRAN (Single Radio Access Network, a multi-standard wireless access network) as the mainstream trend of future baseband evolution, the number of boards that may be configured in each baseband frame will be more and more, up to 8 blocks. If a single board is stacked, the number of boards will increase by several times to several tens of times.

The power supply of the existing BBU is powered by supplying 12 volts to the fixed bus voltage. The power supply efficiency of the board is fixed, such as converting 12 volts to 1.5 volts or converting 12 volts to 3.3 volts. Wait. Assuming that the power consumption of the single board is about 70 watts and the fixed voltage of the bus voltage is 12 volts, the voltage conversion efficiency of the power chip on the single board (that is, 12 volts to 1.5 volts) is very low, so the power chip has a large conversion loss. Fixed voltage power supply mode For this case, the bus voltage cannot be dynamically adjusted, and the voltage conversion efficiency of the power chip is fixed, so the system loss is increased. When the power consumption of the single board is low, the fixed voltage power supply mode cannot dynamically adjust the bus voltage, which makes the system power loss large, and the operator can save the power of the OPEX (operating Expense operation cost). At lower times, reducing the power loss of the system is an important issue to be solved.
