A base station, or a public mobile communication base station, is a form of radio station. It refers to a radio transceiver station that transmits information between a mobile phone terminal through a mobile communication exchange center in a certain radio coverage area. In order to ensure the normal operation of a communication base station and avoid being unable to use it due to an unexpected power outage, a reserve device is usually set up as a backup power source, and DCDC is a key device when the backup power source is used. After searching, it is found that a typical base station reserve device in the prior art is a battery management system suitable for a communication base station, such as the publication number CN115833330A, including: a battery management module, a communication module, a main control module, a DCDC bidirectional module, and a data acquisition module. There are multiple DCDC bidirectional modules and data acquisition modules, each of which is connected to a data acquisition module; the main control module is respectively connected to each data acquisition module and each DCDC bidirectional module, and the DCDC bidirectional module is connected to the busbar and the lead-acid battery pack. The main control module is respectively connected to each data acquisition module and each DCDC bidirectional module. Its main feature is to collect data from battery packs one by one, charge and discharge each battery pack appropriately, reduce damage to each battery, extend the battery life, and thus reduce the operating costs of communication base stations.

[0003] In summary, the existing communication base station reserve device obtains relevant information of the battery pack when switching the working state of the battery pack through DCDC, but cannot synchronously obtain the DCDC working state that controls the battery pack, which may easily lead to the battery pack being unable to supply and charge normally due to incomplete information, thereby increasing the operating cost of the base station. In view of the above problems, it is necessary to improve the existing equipment. Summary of the invention

[0020] In a further embodiment, the number of DCDC modules is the same as that of battery packs and data acquisition modules, and the DCDC modules correspond to the battery packs and data acquisition modules one by one.

[0021] In a further embodiment, the data content of the DCDC module 1 collected by the data collection module 2 includes normal start and stop of the DCDC module 1 and the power supply current.

[0022] In a further embodiment, the reserve battery module data content collected by the data collection module 2 includes the battery power, the battery charging time, the battery power supply time, and the battery power supply and charging times.

[0023] In a further embodiment, the control and analysis module 3 controls the DCDC module 1 through an algorithm to sequentially power and charge multiple battery packs in the reserve battery module, and the control and analysis module 3 monitors and predicts the working status of the battery module through the data acquisition module 2.

[0024] In a further embodiment, the control and analysis module 3 uses a weighted polling method to sequentially charge and supply power to the battery pack. The weighted polling method assigns different weight values ​​to different battery packs based on a polling algorithm. The weighting basis of the weighted polling method includes the number of times the battery pack is powered, the remaining power of the battery pack, the charging time of the battery pack, and whether there is an abnormality in the corresponding DCDC module.

[0025] In a further embodiment, the control and analysis module 3 performs assignment according to the actual conditions of the battery pack, and the assignment operation is controlled by human settings.

[0026] In a further embodiment, the implementation steps of the weighted polling method are: traverse the server list currentWeight from the beginning, currentWeight + the weight of the battery group, and then compare it with the sum of the weights of all battery groups; when the currentWeight is greater than or equal to the sum of the weights of all battery groups, traverse the battery group list from the beginning and set the currentWeight to 0; repeat the above steps until a battery group is found that satisfies the condition that the currentWeight is greater than the currentWeight and less than or equal to the sum of the weights of all battery groups, then the battery group is considered to be selected.

[0027] In a further embodiment, the principle of the weighted polling method is: in the battery module array S, first calculate the maximum value max of all battery module weights and the greatest common divisor gcd of all battery module weights; index represents the index of the battery module selected when this request arrives, and the initial value is -1; current_weight represents the current scheduled weight, and the initial value is max; when a request arrives, poll the battery module array S starting from index+1, and find the first battery module whose weight is greater than current_weight to process the request; record its index in the result sequence, and when polling the server array, if the end of the array is reached, start searching from the beginning and reduce the value of current_weight: current_weight -=gcd, if current_weight is equal to 0, reset it to max.

[0029] Specifically, in the actual working process, the multiple data acquisition modules in the data acquisition module 2 collect relevant information of the corresponding battery packs and DCDC modules, and input the collected information to the control and analysis module 3. The control and analysis module 3 analyzes the relevant information of the received battery pack, and combines and analyzes the working data of the DCDC module used to switch and control the battery pack, and then obtains the power supply sequence of all battery packs through a weighted polling algorithm. That is, when the external power supply of the base station is accidentally cut off, the power supply sequence calculated by the weighted polling algorithm will be used to control the corresponding battery packs to power the base station in turn, and at the same time, the corresponding DCDC modules will synchronously switch to cooperate with the power supply operation of the corresponding battery pack. When the battery pack is exhausted, the next battery pack and its corresponding DCDC module continue to supply power, and so on.

[0030] On the other hand, when the external power supply is normally involved, the control and analysis module 3 cooperates with the DCDC module 1 to charge the battery pack used for power supply according to the order of power supply, and the corresponding DCDC module plays an auxiliary role in charging. In addition, the weighted polling algorithm adjusts the charging time of the battery pack according to the power supply time, power supply times and other relevant data of the battery pack, so as to avoid overcharging of the battery pack.

[0032] The control analysis module 3 adopts the autoregressive integrated moving average model to analyze and predict the current data of all battery packs collected by the data acquisition module 2 with the historical data stored in the backup management module 4 as the comparison sample, that is, to predict the hidden dangers of all battery packs, so as to facilitate the inspection and maintenance of the relevant battery packs according to the prediction results.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
