Detailed Description
To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
For large-scale electric equipment such as a base station, once power is cut off, the power may have a large influence. Therefore, a battery is generally provided as a backup power supply, and the battery is used for supplying power after the commercial power is cut off.
However, the capacity of the battery is limited after all, and as the service life increases, the performance also decreases, and the capacity decreases. In order to reduce the situation of complete power failure of the base station, it is very important to grasp the performance state of the storage battery in time, namely the capacity of the storage battery. Otherwise, it is difficult to generate power in time to avoid the base station breaking and interrupting the service, and related support data for expanding and replacing the storage battery cannot be provided.
The battery capacity is generally characterized by a discharge time period. The measurement of the capacity of the storage battery has been a problem which is difficult to solve in the industry. In the traditional storage battery performance research, the following test methods are mainly adopted:
(1) impedance method: a small-amplitude sine wave current or voltage signal is used as an excitation source and injected into the storage battery, the internal resistance of the storage battery is calculated by measuring a response signal of the small-amplitude sine wave current or voltage signal, and then relevant parameters of the storage battery are obtained, and the performance of the storage battery is determined;
(2) off-line discharge test method: separating one group of storage batteries from the direct current system, performing discharge test on an external dummy load, returning the dummy load to the direct current system, and performing discharge test on the other group of storage batteries by the same method after the charging is recovered so as to determine the performance of the storage batteries;
(3) on-line discharge test method: the AC charging input of the storage battery is disconnected, the storage battery supplies power to an actual load, and data such as voltage, discharging time and discharging current of the storage battery are measured and recorded to determine the performance of the storage battery.
However, the conventional storage battery capacity testing methods are complex to implement in practice, generally require an external testing instrument and meter, and have a long testing time. For mobile operators, the number of base stations is huge, the workload for testing the capacity of the storage batteries of numerous base stations by the traditional means is huge, and the cost is higher, so that the capacity condition of the storage batteries is difficult to obtain in time, and the operation and maintenance work efficiency is not improved.
Based on the above problems, the present application proposes a method for predicting the capacity of a battery more easily, conveniently and quickly, which plays a guiding role in the power supply structure of a base station and the management of the battery.
In general, a base station management system is provided to facilitate centralized management of base stations. In a base station management system, there is generally an alarm definition reflecting a change in input voltage of a base station. And the change of the input voltage can be caused when the power supply structure of the base station is changed. For example, when the mains supply is normal, the input voltage is a stable value (typically around 53V), and when the mains supply is disconnected from the battery, the input voltage gradually decreases from the float voltage (i.e. the highest charging voltage of the battery, typically 53V). That is, the alarm caused by the voltage change can reflect the power supply state of the base station to a certain extent.
Fig. 1 is a schematic view of an application scenario provided in the present application. As shown in fig. 1, the commercial power or the storage battery supplies power to the base station device, and the supply voltage is an input voltage. And the network management server manages the state of the base station equipment and monitors the change of the input voltage. Therefore, the power supply time of the storage battery is counted conveniently, and the performance of the storage battery is predicted.
Specific implementations can be found in the following examples.
Fig. 2 is a flowchart of a method for managing a storage battery according to an embodiment of the present application, where the method of the present embodiment may be applied to an electronic device. As shown in fig. 2, the method of this embodiment may include:
s201, obtaining the issuing time of the input voltage abnormity warning information.
The input voltage abnormity warning information is issued by the base station management system when the input voltage of the target base station is detected to be lower than the preset standard input voltage.
In this embodiment, the electronic device may be integrated with a base station management system (for example, a network management server in the embodiment corresponding to fig. 1), or may be a device that separately implements the storage battery management method.
When the base station management system detects that the input voltage of the base station is lower than the preset standard input voltage, input voltage abnormity warning information is generated, and meanwhile, the time for issuing the warning is sent to the electronic equipment.
The preset standard input voltage can be set according to the mains voltage. For example, the standard input voltage may be a mains voltage. It is considered that the mains voltage is not absolutely stable, but relatively stable, with possible small voltage variations within a certain range. Thus, the standard input voltage may also be a certain voltage value that is smaller than the mains voltage.
In some embodiments, the base station device itself has a voltage detection means for detecting the input voltage, and the input voltage data is transmitted directly to the base station management system or transmitted to the base station management system through the base station device.
In other embodiments, a single voltage detection device may be used to detect the input voltage of the base station equipment and then directly transmit the input voltage data to the base station management system.
S202, determining the current total service time of the standby storage battery of the target base station according to the issuing time of the voltage abnormity warning information.
In the present application, the total usage period refers to the cumulative usage period of the storage battery from the beginning of use; the current total usage time period refers to the cumulative usage time period of the storage battery from the beginning of usage to the present.
The capacity of the battery is also affected by the lifetime, and the longer the battery is used, the smaller the capacity of the battery is, and the time required for single use is shortened. Thus, the current total usage period may be used as a reference factor for the prediction of the battery capacity.
S203, determining the predicted value of the maximum power supply time of the storage battery at this time according to the incidence relation between the maximum single power supply time and the total use time of the storage battery and the current total use time.
As a standby power supply, the storage battery can start to supply power when the mains supply is powered off until the maximum output power or the minimum power supply voltage or the mains supply is recovered, and in the application, the process is used as single power supply.
The maximum time length of single power supply refers to the maximum time length which can be reached by the single power supply of the storage battery, and the discharge capacity of the storage battery, namely the battery capacity, can be represented. And the incidence relation between the maximum time length of single power supply and the total service time length can represent the incidence relation between the battery capacity and the battery service life. Based on the incidence relation and the current total using time length, a predicted value of the maximum time length of the current power supply, namely the current battery capacity can be obtained.
Wherein, the maximum time length of single power supply can be obtained through historical records.
And S204, if the predicted value of the maximum power supply duration is less than a preset threshold value, outputting prompt information for replacing the storage battery.
If the prediction result shows that the maximum time of the current power supply is short, the storage battery may need to be replaced, so that the communication problem caused by the power failure of the base station is avoided.
The storage battery management method provided by the embodiment is applied to electronic equipment and comprises the following steps: acquiring the issuing time of input voltage abnormity warning information, wherein the input voltage abnormity warning information is issued when a base station management system detects that the input voltage of a target base station is lower than a preset standard input voltage; determining the current total use time of a standby storage battery of the target base station according to the issuing time of the voltage abnormity warning information; determining a predicted value of the maximum power supply time of the storage battery at this time according to the incidence relation between the maximum single power supply time and the total use time of the storage battery and the current total use time; and if the predicted value of the maximum power supply duration is less than the preset threshold, outputting prompt information for replacing the storage battery. Based on the existing power supply structure of the base station, the performance of the standby storage battery of the base station is detected, so that the performance of the storage battery is analyzed quickly and efficiently, and prompt information is output when the performance of the storage battery is poor to prompt the replacement of the storage battery.
In a specific embodiment, before determining the predicted value of the maximum power supply time of the storage battery according to the incidence relation between the maximum single power supply time and the total use time of the storage battery and the current total use time, the method may further include: acquiring the maximum power supply time of the storage battery all the time and the total service time of stopping the current power supply; and determining the association relationship between the maximum single-power-supply time length and the total use time length of the storage battery according to the maximum previous power-supply time length of the storage battery and the total use time length of the current power supply.
The incidence relation between the maximum power supply time of a single time and the total use time can be accurately determined by utilizing the maximum power supply time of the previous time and the total use time of the current power supply, and the maximum power supply time of this time is predicted.
In some embodiments, the above battery management method may further include: and acquiring the environmental temperature information of the storage battery when the storage battery is powered. Correspondingly, the determining the association relationship between the maximum time length of single power supply and the total time length of use of the storage battery according to the maximum time length of power supply of the storage battery over the past and the total time length of use of power supply at the present may include: and determining the association relationship between the single power supply time length and the total use time length of the storage battery at different temperatures according to the maximum power supply time length of the storage battery all the time, the total use time length of the power supply at the time of stopping and the environment temperature information at the time of the power supply.
The battery capacity of the storage battery is closely related to the ambient temperature, so that in order to predict the battery capacity more accurately, the ambient temperature factor can be increased, and the correlation between the single power supply time length and the total service time length of the storage battery at different temperatures is determined, so that the maximum power supply time length at this time can be predicted more accurately.
Specifically, the temperature at the time of issuing the input voltage abnormality warning information may be acquired when the current battery capacity is predicted. Correspondingly, the determining the predicted value of the maximum power supply time of the storage battery according to the incidence relation between the maximum single power supply time and the total use time of the storage battery and the current total use time may include: and determining the predicted value of the maximum power supply time of the storage battery at this time according to the incidence relation between the maximum single power supply time and the total use time of the storage battery at the temperature when the input voltage abnormity warning information is issued and the current total use time.
And determining the incidence relation between the maximum single power supply time length and the total service time length of the storage battery at the corresponding temperature according to the temperature when the input voltage abnormity warning information is issued, and determining the predicted value of the maximum current power supply time length of the storage battery according to the incidence relation. The predicted value can be more accurate.
In some embodiments, to ensure that the life of the battery is not unduly consumed, an input voltage threshold is generally set, which is actually the threshold of the output voltage of the battery. After the threshold value is lower, the power supply of the storage battery is stopped to prevent excessive loss. If the commercial power is not recovered at this time, the base station will be completely powered off. For the power-off condition, a network element chain-breaking alarm message can be set. And when the network element chain breakage alarm is issued, the storage battery stops supplying power. That is to say, the maximum time of single power supply of the storage battery in one power supply is the time from the input voltage abnormity warning information release to the network element chain breakage warning information release.
The maximum single-power-supply duration can be determined in the above manner, and accordingly, after new maximum single-power-supply duration data is acquired each time, the association relationship between the maximum single-power-supply duration and the total use duration can be updated. Specifically, the method may include: if the predicted value of the maximum power supply duration is greater than or equal to a preset threshold, acquiring the release time of network element chain breakage alarm information, wherein the network element chain breakage alarm information is released when a base station management system detects that the input voltage of a target base station is lower than the preset threshold input voltage; determining the true value of the maximum power supply time of the storage battery according to the release time of the input voltage abnormal alarm information and the release time of the network element broken link alarm information; and updating the incidence relation between the single power supply maximum time and the total use time of the storage battery according to the true value of the current power supply maximum time and the current total use time of the storage battery.
Through updating and correcting, the incidence relation between the maximum power supply time and the total service time can be closer to a real relation, and the prediction value of the next maximum power supply time can be more accurate.
By the scheme, the electric quantity of the storage battery can be predicted in a simpler mode without other devices, and the standby storage battery can be replaced, maintained and the like in a targeted mode. Has important significance for the maintenance of the base station equipment.
In a specific embodiment, the management of the storage battery of the zhongxing LTE base station is taken as an example for explanation. 3G/4G/5G base stations, or other manufacturer base stations.
When the mains supply input is normal, the input voltage of the base station is generally about 53V; when the mains supply is cut off, the storage battery starts to discharge from the floating charge voltage (namely the highest charge voltage of the storage battery, generally 53V) and gradually drops, and when the voltage is lower than a threshold, the base station reports an input voltage abnormal alarm. For example, the threshold value is 50, and when the input voltage of the base station is 47.9V, the threshold value is lower than the threshold value, so the alarm is reported. An "alarm recovery value" may also be set to clear the alarm when the base station input voltage is above the recovery value.
Of course, the closer the "threshold value" is to the float voltage 53V of the battery, the closer the alarm time is to the actual discharge time of the battery. However, in order to avoid false alarms that may be caused by a back-and-forth jump in the battery voltage, it is prudent to set the alarm threshold to 50V, which means that the battery has been determined to start discharging when the alarm occurs.
It should be noted here that a small difference between specific values of the threshold value does not greatly affect the discharge time of the storage battery, and more importantly, the discharge time is used to represent the discharge capacity of the storage battery. Therefore, the occurrence time of the "input voltage abnormality warning" can be regarded as the start time of the battery discharge.
In the Zhongxing LTE network management system, the "network element chain breakage alarm" corresponds to a base station breakage alarm. When the storage battery is discharged, in order to protect the storage battery and prolong the service life of the storage battery, parameters of 'primary power-off voltage' and 'secondary power-off voltage' are generally set for the storage battery. The primary power-off voltage means that when the output voltage of the storage battery is lower than the threshold, a primary power-off load, such as a main device with high power consumption, such as a base station, is disconnected; "secondary power down voltage" means that a "secondary power down load", such as a relatively important transmission device, will be turned off when the battery output voltage is below this threshold. The "primary power-down voltage" is set to be higher than the "secondary power-down voltage".
Therefore, when the "network element chain breakage alarm" occurs, it means that the output voltage of the storage battery is already lower than the "one-time power-off voltage" to cause the base station to be interrupted. The "primary power down voltage" of the battery can be set to 46.5V, that is to say the base station will be interrupted when the battery output voltage is below 46.5V.
Based on the above settings of the correlation threshold values for the two types of alarms, a graph as shown in fig. 3 may be plotted. As shown in fig. 3, the battery starts to discharge from the float voltage of 53V (time point t0), and reports an alarm to the network management server when the voltage is lower than 50V (time point t1), and the base station interrupts and reports an alarm when the battery voltage is lower than 46.5V (time point t 2). Therefore, (t2-t0) is the time period from the battery to the next power-off voltage value, but since the time point t0 cannot be accurately obtained, the time period from (t2-t1) can be approximated as the discharge time period of the battery, and if the alarm threshold value is further modified to be closer to the float voltage 53V, the time period from t1 to t0, that is, (t2-t1) can be further closer to (t2-t 0). The current discharge capacity or battery capacity of the storage battery can be represented by the discharge time length of one time.
The above measures do not need to change any hardware connection of the base station, do not influence the service of the base station, are simple, safe and practical, are very convenient to realize and easy to popularize, can perfectly solve the technical problems mentioned in the application, and have very practical significance.
According to the storage battery management method, the high-low set voltage threshold of the power supply object (taking a base station as an example) is reasonably set, and the discharge time of the storage battery between the high-low set voltage is automatically recorded by the power supply object, so that the capacity information of the storage battery is obtained. The method avoids various defects of directly measuring the storage battery, obtains the capacity of the storage battery by utilizing the attribute of the power-supplied object, is simple, convenient and efficient, and is easy to perform data processing.
