The method achieves the accurate calculation of the system energy consumption, the energy consumption of each part corresponds to an entity physical unit carrier, when the system structure of a signal processing algorithm is changed, the caused energy consumption change can also be precisely detected in real time, and important reference is provided for energy consumption detection and control of the LTE wireless private network.

Description

technical field [0001] The invention relates to the technical field of power communication, in particular to a method for detecting energy consumption of an LTE wireless private network based on a C-RAN architecture. Background technique [0002] The amount of data in the electric power industry has increased rapidly in recent years, especially the distribution network automation and metering automation end services on the distribution side below 10kV, which are faced with the needs of wide areas and multiple accesses. The traditional optical fiber coverage method is slow to work, and LTE wireless private network is urgently needed as its supplementary means of communication. [0003] Therefore, the power supply unit built its own LTE (Long Term Evolution, long-term evolution plan) wireless private network, hoping to obtain higher system bandwidth and faster service access effects to meet the needs of distribution network automation and metering automation. While using OFDM...

Problems solved by technology

[0012] (3) The radio frequency unit RRH is connected to the central baseband processing unit BBU through optical fiber, which requires the corresponding CPRI (Common Public Radio Interface, common public radio interface) optical / electrical conversion interface, and the traditional energy consumption model does not include CPRI interface and its energy consumption;

[0013] (4) Multiple radio frequency units RRH connected to the central baseband processing unit BBU through optical fiber can improve system throughput through cooperative transmission, but the traditional energy consumption model does not take into account the computational complexity brought about by this cooperative transmission and energy consumption

[0014] Based on the analysis of the above problems, the existing energy consumption detection technology has been unable to meet the requirements of the LTE wireless private network energy consumption detection of the C-RAN architecture. The accuracy of the detection results is low, and it is difficult to obtain a more accurate total energy consumption of the system.
