Problems solved by technology

Because this method uses performance parameters and battery life decline curve to fit the battery life time, the accuracy of the fitted life time is usually low.
In addition, the temperature of the battery pack and the number of charge and discharge times will affect the battery life, and the fitted life time cannot take these parameters into account, thereby reducing the accuracy of the estimated time

Embodiment Construction

[0068] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details. In other examples, some technical features known in the art are not described in order to avoid confusion with the present invention.

[0069] The applicant's research found that there are currently two main methods for evaluating battery life, which are the discharge test method and the performance estimation method.

[0070] 1. Disadvantages of discharge test method

[0071] A. The discharge test method makes the backup battery work by simulating the power failure of the mains. When the backup battery fails, it may directly cause the base station equipment to be powered off, resulting in equipment failure, so the discharge test method has certain risks. .

[0072] B. Because the discharge t...

Abstract

The present invention provides a method and system for predicting the battery life time of a base station backup battery. The prediction method includes the following steps: accessing alarm data; processing alarm data; vectorizing alarm fields; accessing resource data; time for data integration. The invention designs a model for calculating the endurance performance by accessing alarm and resource data, and also designs a processing method for the input data of the model. The battery life of the backup battery can be automatically discovered through the calculation of the model. In addition, through the integration of data settings, the accuracy of battery life calculation is improved. By setting the three modes of detachment alarm trigger, power failure alarm trigger, and RRU out-of-service alarm trigger, the full-dimensional battery life calculation on the RRU side and the BBU side of the base station is realized.

Description

technical field [0001] The invention relates to the field of G06F: electrical digital data processing, in particular to a method for predicting the battery life of a base station backup battery. Background technique [0002] The base station is the interface device for wireless devices to access the communication network, and undertakes the responsibility of connecting the last mile of network coverage. At the same time, because base stations are often deployed in outdoor environments, they are easily affected by external environmental factors, such as natural disasters, construction damage, and power outages by owners, etc., resulting in interruption of equipment power supply. At present, after the base station is powered off, in order to ensure the continuous operation of the equipment, the method of deploying backup power is usually adopted. Once the mains power is interrupted, it will switch to the backup battery pack to continue power supply. According to the operation...
