Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
The embodiment of the invention provides a method for evaluating a base station storage battery, which is applied to a mobile terminal and comprises the following steps of:
The mobile terminal is in wireless communication connection with the base station, and discharge parameters of the base station storage battery in the discharge process can be acquired through the connection between the mobile terminal and the base station.
The process of obtaining the discharge parameters of the storage battery of the base station comprises the following steps: the operation and maintenance monitoring platform is connected with a data acquisition unit at the base station side, and instruction information is sent to the data acquisition unit, so that the data acquisition unit sets parameters of the base station storage battery according to the instruction information and discharges the base station storage battery; receiving discharge parameters of a base station storage battery sent by a data acquisition unit in a discharge process; the discharge parameters at least include: the corresponding time length when the storage battery of the base station discharges to the set voltage, the capacity Q of the storage battery of the base station, the total load current I and the corresponding temperature value t of the storage battery of the base station.
The mobile terminal is connected with an operation and maintenance monitoring platform, and the operation and maintenance monitoring platform is connected with a data collector at a base station side, wherein the data collector is an FSU (Field super vision Unit). After the mobile terminal is connected with the operation and maintenance monitoring platform and the operation and maintenance monitoring platform is connected with the data acquisition unit, the mobile terminal is connected with the base station.
At the moment, the mobile terminal sends instruction information to a data acquisition unit on the base station side, and after the data acquisition unit acquires the instruction information, the floating charge voltage of the base station storage battery is set according to the instruction information, wherein the floating charge voltage is the termination discharge voltage of the base station storage battery set by a user. Meanwhile, the data acquisition unit needs to trigger the storage battery of the base station to discharge. In the process of discharging the storage battery of the base station, the data acquisition unit acquires the discharge parameters of the storage battery of the base station. And after acquiring the discharge parameters, the data acquisition unit sends the discharge parameters to the mobile terminal. Wherein the discharge parameters collected by the data collector at least comprise: the corresponding time length when the storage battery of the base station discharges to the set voltage, the capacity Q of the storage battery of the base station, the total load current I and the corresponding temperature value t of the storage battery of the base station.
It should be noted that, in order to accurately evaluate the real performance of the base station storage battery, a normative requirement needs to be made on the acquired data before data acquisition, and the evaluation benchmarks for data analysis are unified. In order to meet the accuracy of subsequent data analysis and evaluation, the granularity of data acquisition of the current operation and maintenance monitoring platform is one point in 30 minutes, in order to evaluate analysis requirements and hardware operating environments, 2 minutes are taken as a statistical period in compromise, and acquired data comprise system time, storage battery voltage, storage battery current and the like.
After the discharge parameters of the base station battery are acquired, step 102 is performed.
And 102, acquiring actual discharge time and theoretical discharge time corresponding to the base station storage battery according to the discharge parameters of the base station storage battery.
And after the discharge parameters acquired by the data acquisition unit are acquired, determining the actual discharge time corresponding to the base station storage battery according to the discharge parameters. The discharging parameters comprise the corresponding time length when the storage battery of the base station discharges to the set voltage, and when the actual discharging time length is obtained, the corresponding time length when the storage battery of the base station discharges to the set voltage is determined to be the actual discharging time length T1. And the data acquisition unit starts timing when the storage battery of the base station starts discharging, stops timing when the storage battery of the base station is finished, and acquires the corresponding time length when the storage battery of the base station discharges to the set voltage.
And when the theoretical discharge time length corresponding to the base station storage battery is obtained, determining the theoretical discharge time length T2 according to the capacity Q of the base station storage battery, the total load current I and the temperature value T corresponding to the base station storage battery.
The step of determining the theoretical discharge time length T2 according to the capacity Q of the base station storage battery, the total load current I and the temperature value T corresponding to the base station storage battery comprises the following steps: determining a theoretical discharge time period T2 by adopting a preset calculation formula:
T2＝Qη[1+α(t-25)]/KI
wherein eta is a discharge capacity coefficient, and the corresponding value is between 0.4 and 1; alpha is a temperature coefficient, and the corresponding value is 0.01, 0.006 or 0.008; k represents a safety factor and is a constant value.
And when the theoretical discharge time length is calculated, the acquired capacity Q of the base station storage battery, the acquired total load current I and the temperature value t corresponding to the base station storage battery are all brought into a preset calculation formula for calculation. The discharge capacity coefficient η in the preset calculation formula corresponds to a value range, and the value of the discharge capacity coefficient needs to be determined according to the discharge time corresponding to the base station storage battery. K represents a safety factor, corresponding to a value of 1.25. The temperature coefficient alpha determines a corresponding value according to the discharge time length.
For the discharge capacity coefficient η, the values correspond to different values under different discharge time periods, and the corresponding relationship between the discharge capacity coefficient η and the discharge time periods can be seen in table 1.
| Discharge time (hours) of base station accumulator | Discharge capacity coefficient η |
| 0.5 | 0.4 |
| 1 | 0.45 |
| 2 | 0.61 |
| 3 | 0.75 |
| 4 | 0.79 |
| 5 | 0.83 |
| 6 | 0.87 |
| 7 | 0.91 |
| 8 | 0.94 |
| 9 | 0.98 |
| 10 | 1 |
| Greater than 20 | 1 |
TABLE 1
According to table 1, it can be seen that the discharge capacity coefficient η gradually increases when the actual discharge time of the base station storage battery increases, that is, the discharge capacity coefficient η increases with the increase of the actual discharge time of the base station storage battery, the discharge capacity coefficient η is positively correlated with the actual discharge time of the base station storage battery, and the discharge capacity coefficient η is between 0.4 and 1. And when the discharge time of the storage battery of the base station is more than or equal to 10, the corresponding discharge capacity coefficient is a fixed value 1. When the preset calculation formula is used for calculation, the value of the discharge capacity coefficient η needs to be determined according to the corresponding relation in table 1 according to the actual discharge duration corresponding to the base station storage battery.
When the temperature value t corresponding to the base station storage battery is obtained, for a single base station storage battery, the corresponding temperature is determined, and the actual temperature value of the test station is selected for calculation.
For the temperature coefficient alpha, the value of the temperature coefficient alpha needs to be determined according to the actual discharge time of the base station storage battery, the temperature coefficient alpha is reduced along with the increase of the actual discharge time of the base station storage battery, and the temperature coefficient alpha is negatively correlated with the actual discharge time of the base station storage battery. When the actual discharge time of the base station storage battery is less than or equal to 1h, the value of the temperature coefficient alpha is 0.01; when the actual discharge time of the base station storage battery is longer than 1h and less than or equal to 10h, the value of the temperature coefficient alpha is 0.008; when the actual discharge time of the base station storage battery is longer than 10h, the value of the temperature coefficient alpha is 0.006.
After the actual discharge time period and the theoretical discharge time period of the base station battery are determined, step 103 is executed.
And 103, determining the effect value of the base station storage battery according to the actual discharge time length and the theoretical discharge time length corresponding to the base station storage battery.
It should be noted that currently, the mainstream measured capacity of the storage battery is measured according to the 0.1C standard, but the station power consumption currents in the existing network are different, and the capacity of the discharged storage battery cannot be directly evaluated to evaluate the performance loss of the storage battery.
After the actual discharge time length and the theoretical discharge time length corresponding to the base station storage battery are obtained, the ratio of the actual discharge time length to the theoretical discharge time length is obtained, and the ratio is determined as the base station storage battery effect value.
The process of determining the base station battery efficiency value according to the actual discharge time length T1 and the theoretical discharge time length T2 is as follows: and the base station storage battery efficiency value is equal to the actual discharge time period T1/theoretical discharge time period T2.
After the base station battery performance value is obtained, step 104 is performed.
And 104, evaluating the base station storage battery according to the efficiency value of the base station storage battery to obtain an evaluation result.
After the effect value of the base station storage battery is obtained, an evaluation result corresponding to the effect value of the base station storage battery is obtained in the corresponding relation between the pre-generated effect value and the evaluation information, and the evaluation of the base station storage battery is realized.
In the embodiment of the invention, the efficiency loss condition of the storage battery can be intuitively judged according to the on-line battery time efficiency and the matching property with the actual discharge performance of the storage battery, and the discharge is the actual discharge time obtained according to the actual current network load test, so the backup time capacity of the station discharge is directly reflected, and the invention has strong data persuasion.
Taking the online discharge test data of the storage battery of the base station as an example, the technical scheme of the invention is applied to carry out specific analysis, as shown in fig. 2.
The specification of the base station storage battery is 150AH/48V, the tested average current is 10.54A, discharging to the set voltage of 47V takes 667 minutes (11.1 hours), and therefore the actual discharging time of the current base station storage battery is 11.1 hours. For a specific base station storage battery at present, the corresponding environment temperature of the base station storage battery is 25 ℃, t is 25 ℃, η is 1, α is 0.006, Q is 150AH, and the theoretical discharge time length is calculated to be 11.38 hours, so that the base station storage battery efficiency value is actual discharge time length (11.1h) ÷ theoretical discharge time length (11.38h), and the base station storage battery efficiency value is 0.9766.
According to the technical scheme, on the premise of meeting network operation safety, on the basis of existing network resources and a monitoring system, the storage battery is subjected to remote automatic discharge test, real online time efficiency of the on-line storage battery is output through scientific data acquisition and analysis, the endurance evaluation of the storage battery is obtained, the storage battery can be fully utilized, the network stability is improved, the operation cost is reduced, and engineering project management and daily network operation are better served.
In the above scheme of the embodiment of the present invention, the battery efficiency value of the base station may actually reflect the loss condition of the battery, but this is based on the parameter obtained after deep discharge of the battery at 47V, and in the actual work of battery asset management, a manager may only want to know whether the battery efficiency condition is lower than a given critical state, rather than an accurate value, so as to quickly determine whether scrapping replacement is required. Therefore, the method of the embodiment of the invention further comprises the following steps:
acquiring a discharge curve sample corresponding to a critical state of a base station storage battery; and evaluating the storage battery of the base station according to the relevant parameters of the storage battery of the base station and the discharge curve sample.
The critical state of the base station battery may be a critical scrapping state, and the critical scrapping state may be set by a person skilled in the art. When obtaining a discharge curve sample corresponding to a critical state, first setting a first performance value corresponding to a base station storage battery of the critical state; and acquiring a discharge curve corresponding to the first effect value, determining an efficacy characteristic voltage curve under each discharge multiplying factor according to the discharge curve corresponding to the first effect value, and determining the efficacy characteristic voltage curve under each discharge multiplying factor as a discharge curve specimen.
Specifically, according to the requirements of engineering management, a first efficiency value corresponding to a critical scrapping state is set, discharge curves (voltage and current) of the first efficiency value of the critical scrapping state are collected and accumulated, typical efficiency characteristic voltage curves under various discharge rates are analyzed to be used as efficiency characteristic voltage curves, the efficiency characteristic voltage curves under various discharge rates form a database, and the efficiency characteristic voltage curves under various discharge rates stored in the database are determined to be discharge curve samples.
After the discharge curve sample is determined, the step of evaluating the base station storage battery according to the relevant parameters of the base station storage battery and the discharge curve sample comprises the following steps:
acquiring the corresponding discharge multiplying power of a base station storage battery, and acquiring the voltage value of each test time point corresponding to the current discharge multiplying power within a preset time length; determining a first discharge curve sample corresponding to the current discharge rate; comparing the voltage value at each test time point with the corresponding voltage value in the first discharge curve sample, and obtaining the evaluation result of the base station storage battery according to the comparison result; and the corresponding test interval duration between the adjacent test time points is equal, and the voltage value corresponding to the first discharge curve sample is obtained at each test time point.
For a base station storage battery to be evaluated, corresponding discharge multiplying power needs to be obtained, a plurality of test time points are selected in preset time length, interval time lengths between adjacent test time points are equal, a corresponding voltage value is obtained for each test time point, and the interval time lengths between the adjacent test time points are equal.
According to the discharge multiplying power of the base station storage battery to be evaluated, a first discharge curve sample corresponding to the discharge multiplying power of the current base station storage battery is determined in the discharge curve samples, the voltage values of the obtained testing time points are compared with the voltage values corresponding to the corresponding testing time points in the first discharge curve sample, the difference between the voltage values of the storage battery to be evaluated and the critical scrapped state curve sample can be judged quickly, through evaluation of the voltage values corresponding to the testing time points, comparison data of the base station storage battery and the critical scrapped state curve sample battery efficiency can be evaluated without waiting for the completion of the discharge of the storage battery, and then the storage battery is evaluated in comparison with the critical scrapped state sample battery efficiency.
And when the voltage value of each test time point is compared with the corresponding voltage value in the first discharge curve sample, and the evaluation result of the storage battery of the base station is obtained according to the comparison result: in each test time point, when the ratio of the number of the test time points of which the corresponding voltage values are smaller than the corresponding voltage values in the first discharge curve specimen to the number of the total test time points is greater than 1/2, determining that the effect value of the base station storage battery is smaller than a first effect value corresponding to a critical state; and in each test time point, when the ratio of the number of the test time points of which the corresponding voltage values are larger than the corresponding voltage values in the first discharge curve sample to the number of the total test time points is larger than 1/2, determining that the effect value of the base station storage battery is larger than the first effect value corresponding to the critical state.
Specifically, in each test time point of the storage battery to be evaluated, when the voltage values corresponding to more than half of the test time points are all greater than the voltage values corresponding to the first discharge curve specimen, it can be determined that the efficiency value of the base station storage battery is greater than the first efficiency value corresponding to the critical state, and the state of the base station storage battery is superior to the critical scrapped state at this time. In each test time point of the storage battery to be evaluated, when the voltage values corresponding to more than half of the test time points are smaller than the voltage values corresponding to the first discharge curve specimen, it can be determined that the effect value of the storage battery of the base station is smaller than the first effect value corresponding to the critical state, and the state of the storage battery of the base station is inferior to the critical scrapped state.
As shown in fig. 3, the 52% performance cell with the discharge rate of 0.03C is set as the battery performance curve in the critical rejection state, the discharge rate of the tested battery pack is also 0.03C, and we compare the difference with the target curve every 30 minutes, as shown in table 2, it can be found that the voltages at 6 test points are all lower than the target curve, and it can be determined that the performance of the battery pack is below 52%, which is the object that needs to be replaced and modified in our engineering.
TABLE 2
According to the technical scheme provided by the embodiment of the invention, in order to meet the test stability and realize remote discharge test data, the acquired data is stored in the data acquisition unit, and the report terminal is extracted and analyzed after the test is finished. The brand new method for evaluating the battery capacity is used for evaluating according to the ratio of the actual discharge time length to the theoretical discharge time length, and the actual discharge time length is obtained under the actual use condition by performing discharge test according to the actual online load, so that the actual time of the base station working in the actual power failure can be evaluated.
The invention carries out discharge tests under various discharge multiplying powers aiming at the storage battery in the critical scrapping state to obtain a critical scrapping state curve specimen. When the on-grid discharge test is carried out on the on-grid battery, the height of the on-grid battery and the height of the curve specimen are judged by selecting a plurality of time period points and comparing and analyzing the voltage of the on-grid battery and the voltage of the critical scrapped state curve specimen at the same period point, so that the quick judgment is made, and the requirements of technicians are met.
An embodiment of the present invention further provides an evaluation method for a base station battery, which is applied to a base station, and as shown in fig. 4, the method includes:

Specifically, when the discharging parameters are obtained, the base station sets the storage battery according to the obtained instruction information, triggers the storage battery of the base station to discharge after the setting is completed, and collects the corresponding discharging parameters in the discharging process of the storage battery of the base station. When the base station sets the storage battery according to the instruction information, the floating charge voltage of the storage battery needs to be set, wherein the floating charge voltage is the corresponding discharge termination voltage when the storage battery of the base station set by a user stops discharging. The base station side receives instruction information sent by the mobile terminal through the data collector, in order to accurately evaluate the real performance of the base station storage battery, normalization requirements on collected data are required before data collection is carried out, and evaluation benchmarks for data analysis are unified. In order to meet the accuracy of subsequent data analysis and evaluation, the granularity of data acquisition of the current operation and maintenance monitoring platform is one point in 30 minutes, and in order to evaluate analysis requirements and hardware operating environment, 2 minutes can be taken as a statistic period in a compromise mode.
