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...

The invention provides a method and a system for predicting endurance time of a backup battery of a base station. The prediction method comprises the following steps: accessing alarm data; processing the alarm data; vectorizing the alarm field; accessing resource data; calculating out-of-service alarm triggering endurance time, power failure alarm triggering endurance time and RRU out-of-service alarm triggering endurance time; and carrying out data integration on the plurality of endurance times. The invention designs a model for carrying out endurance performance calculation through access alarm and resource data, and also designs a processing method for model input data. And the endurance time of the backup battery can be automatically found through calculation of the model. In addition, through data integration setting, the accuracy of endurance time calculation is improved. Through setting three modes of separation alarm triggering, power failure alarm triggering and RRU out-of-service alarm triggering, full-dimension endurance time calculation of a base station RRU side and a BBU side is realized.
Description
technical field [0001] The present invention relates to the field of G06F: electrical digital data processing, in particular to a method and system 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. Accordi...
