Power saving control method and device of base station BBU

Abstract

The invention relates to a power saving control method and device, in particular to a power saving control method and device of the base station BBU in the communication field. A power supply unit of the based station BBU comprises at least two power supply modules. The power saving control method includes the steps of detecting real-time power consumption of a BBU current collecting unit, judging whether the power consumption is smaller than a set power supply unit optimum efficiency value or not, if yes, enabling the power supply modules to supply power by turns according to set time, and if not, enabling the power supply modules to supply power at the same time. Correspondingly, the power saving control device comprises a power consumption detection module, a controller and a timer. According to the power saving control method and device, the problem that the power consumption of the power supply units of the BBU is large due to the fact that the efficiency of power supply parts of the BBU becomes low after power consumption of the whole BBU is reduced can be solved, dynamic energy saving control in daily running of a BBU machine frame is achieved, energy is saved, consumption is reduced, and meanwhile the service life of the BBU power supply modules is prolonged.

Description

technical field [0001] The invention relates to the field of power-saving control, in particular to a method and device for power-saving control of a base station BBU in the field of communication. Background technique [0002] At present, the power consumption reduction mechanism for BBU (Building Baseband Unit) is mainly by selecting devices with relatively powerful functions, high integration, low power consumption, and simple peripheral circuits at the initial stage of BBU design or by shutting down the device according to the traffic volume of the cell. The digital signal processor (DSP, Digital Signal Processor) or central processing unit (CPU, Central Processing Unit) chip of the baseband board realizes the low power consumption requirement of the whole single board and even the BBU. These technologies can only relatively reduce the power of the baseband part, but do not solve the problem that when the power consumption of the entire baseband part of the BBU becomes l...
