Background
Most devices used in communication networks require power to operate. When the power supply fails and the equipment is suddenly powered off, the storage battery is arranged for ensuring that the equipment can still maintain the operation for a period of time under the condition of sudden power off. The storage battery supplies power to the equipment when the power is suddenly cut off. After the storage battery is used for multiple times, the capacity of the storage battery is lost, so that the time for maintaining the equipment to operate by the storage battery is shortened. Therefore, the capacity of the storage battery needs to be monitored and analyzed so that the storage battery with the capacity not meeting the standard can be replaced by the storage battery with the capacity meeting the standard.
At present, in a communication network, a battery capacity tester is added on each base station side to acquire voltage, discharge current, temperature and other parameters of a battery. And calculating according to the acquired voltage, discharge current, temperature and other parameters to obtain the capacity of the storage battery. However, since the number of base stations in the network is very large, a battery capacity tester is provided for each base station, and a large number of workers must be dispatched to install the battery capacity tester, so that the labor cost for analyzing the capacity of the battery is high.

Detailed Description
Features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a 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 some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention. The present invention is in no way limited to any specific configuration and algorithm set forth below, but rather covers any modification, replacement or improvement of elements, components or algorithms without departing from the spirit of the invention. In the drawings and the following description, well-known structures and techniques are not shown in order to avoid unnecessarily obscuring the present invention.
In the embodiment of the present invention, a method and an apparatus for analyzing battery capacity are described as an example of applying to a communication network. The communication network comprises more than two network elements. In order to prevent the impact of a sudden power failure on the communication network, the network elements are provided with a storage battery. Under the condition that the network element is suddenly powered off due to the failure of a power supply or the failure of a line which originally supplies power to the network element, the storage battery can supply power to the network element. Therefore, the network element can be ensured to be operated for a period of time, the power supply or the line for supplying power to the network element is recovered after the power supply or the line for supplying power to the network element is recovered, and the power supply of the original power supply to the network element is recovered. In the embodiment of the invention, the capacity of the storage battery is analyzed to obtain the capacity variation trend of the storage battery. Therefore, whether the storage battery needs to be processed or not can be judged according to the capacity change trend of the storage battery.
Fig. 1 is a flowchart of a method for analyzing the capacity of a battery according to an embodiment of the present invention. As shown in fig. 1, the battery capacity analysis method includes steps 101 to 104.
In step 101, a power alarm event is obtained from the historical alarm events, and an alarm network element generating the power alarm event is obtained.
The alarm network element is a network element which generates a power supply alarm event in the communication network. The historical alarm events may include, but are not limited to, power alarm events, communication interruption alarm events, and other alarm events. In the embodiment of the invention, the capacity of the storage battery is analyzed mainly based on the power supply alarm event and the communication interruption alarm event. The power supply alarm event occurs to indicate that the original power supply supplying power for the alarm network element stops supplying power.
In one example, the transport network management device may record historical alarm events. Specifically, historical alarm events may be recorded in the form of alarm information. Therefore, the power supply alarm information can be acquired from the historical alarm information, so that the power supply alarm event can be acquired. For example, RELAY-ALARM information (i.e., RELAY ALARM information) and/or PWR-MAJ-ALM ALARM information (i.e., severe under/over voltage ALARM information) may be obtained from the historical ALARM information to thereby obtain a RELAY ALARM event and/or a severe under/over voltage ALARM event.
In step 102, based on the network topology, a neighboring network element communicatively connected to the alarming network element is searched.
In the embodiments of the present invention, the network topology refers to a physical layout of devices (network elements, gateway devices, and the like) interconnected by a transmission medium in a communication network. Here, the "interconnection" may be a wired connection or a wireless connection, and is not limited herein.
According to the network topology structure, the connection relationship between network elements can be known. The network element in communication connection with the alarm network element can be found based on the connection relation of each network element. And the network element in communication connection with the alarm network element is the adjacent network element of the alarm network element.
For example, fig. 2 is a schematic diagram of a network topology according to an embodiment of the present invention. As shown in fig. 2, assuming that the network element 2 is an alarm network element, the network elements adjacent to the network element 2 are the network element 1, the network element 3, and the network element 4 according to the network topology structure.
In step 103, a target communication interruption alarm event generated by a neighboring network element is obtained.
The target communication interruption alarm event is a communication interruption alarm event generated after the alarm network element generates the power supply alarm event, and the first interval duration between the end time of the target communication interruption alarm event and the end time of the power supply alarm event is within the end duration threshold range. The first time interval duration may be set according to an empirical value or a specific scenario, and is not limited herein. For example, the end duration threshold range may be set within 0 to 3 minutes.
The occurrence of the communication interruption alarm event indicates that the communication between the adjacent network element and the alarm network element is interrupted. When the power supply alarm event occurs, the storage battery starts to supply power for the alarm network element. When the electric quantity of the storage battery is exhausted, the alarm network element cannot continuously communicate with the adjacent network element due to the lack of the electric quantity required by operation. The neighboring network element generates a communication disruption alarm event. In the embodiment of the scheme, the capacity of the storage battery is analyzed based on a communication interruption alarm event caused by a power supply alarm event, namely a target communication interruption alarm event.
In one example, the transmission network management device may record the communication interruption alarm event in the form of alarm information. Thereby obtaining target communication interruption warning information corresponding to the target communication interruption warning event and further obtaining the target communication interruption warning event. For example, the receive line side LOSs of signal event may be obtained by R-LOS alarm information (receive line side LOSs of signal alarm information).
In step 104, a capacity variation trend of a storage battery supplying power to the alarm network element is obtained according to the generation time of the power supply alarm event and the generation time of the target communication interruption alarm event.
When a power supply alarm event occurs, the storage battery starts to work and supplies power to the alarm network element. That is, the generation time of the power alarm event is the starting time of the power supply of the storage battery of the alarm network element. When the electric quantity of the storage battery is exhausted, the alarm network element fails to communicate with the adjacent network element, and the adjacent network element generates a target communication interruption alarm event. That is, the generation time of the target communication interruption alarm event is the end time of the power supply of the storage battery of the alarm network element. The end time of the power supply alarm event is the time when the original power supply of the storage battery is restored to supply power to the storage battery. The end time of the target communication interruption alarm event is the time when the alarm network element is in effect (i.e., the alarm network element resumes communication with the neighboring network element). Because the power supply current of the storage battery for supplying power to the alarm network element is stable and known, the corresponding capacity of the storage battery during the current power supply can be obtained. The capacity of the storage battery in different periods can be obtained by using the power supply alarm event and the target communication interruption alarm event in different periods in the historical alarm event, so that the capacity change trend of the storage battery is obtained.
In the method for analyzing the capacity of the storage battery provided by the embodiment of the invention, a power supply alarm event in historical alarm events and a target communication interruption event related to the power supply alarm event are obtained. And obtaining the capacity change trend of a storage battery for supplying power to the alarm network element by utilizing the generation time of the power supply alarm event and the generation time of the target communication interruption alarm event. Compared with the prior art that workers need to be dispatched to install a storage battery capacity tester for each base station to analyze the capacity of the storage battery, in the embodiment of the invention, the capacity change trend of the storage battery is obtained based on the power supply alarm event in the historical alarm event and the target communication interruption alarm event related to the power supply alarm event, so that the capacity analysis of the storage battery is realized. The capacity analysis of the storage battery can be realized without installing a storage battery capacity tester on a base station, and the labor cost for realizing the capacity analysis of the storage battery is reduced.
Fig. 3 is a flowchart of a method for analyzing the capacity of a battery according to another embodiment of the present invention. Fig. 3 differs from fig. 1 in that step 104 in fig. 1 can be specifically subdivided into steps 1041 to 1044 in fig. 3.
In step 1041, a second interval duration between the generation time of the power source alarm event and the generation time of the target communication interruption alarm event is calculated, and the second interval duration is taken as the power supply duration of the storage battery.
That is, the power supply time period of the storage battery is the generation time of the target communication interruption alarm event — the generation time of the power supply alarm event. For example, the generation time of the power alarm event is 2017, 3, 1, 22: 00, the generation time of the target communication interruption alarm event is 3, 3 and 2 in 2017, and 3: 00, the power supply time of the storage battery is 5 hours.
In step 1042, the time period for recording the power on duration is determined.
Wherein the same time period may be determined, or different time periods may be determined. The specific setting of the time period may be determined according to the requirements of the communication network or experience, and is not limited herein. For example, the set time period is 1 month, and the power supply duration is recorded once every month in 2017. For another example, to record the power supply duration from 1 month to 4 months in 2017, the time periods are determined to be 1 month, 2 months and 1 month respectively. That is, the power supply duration is recorded once in 2017, month 1, month 2 to month 3 in 2017, and month 4 in 2017. In order to obtain more accurate data of the capacity variation trend of the storage battery by performing fitting calculation subsequently, the obtained average value of the plurality of power supply time lengths can be positioned at the power supply time length corresponding to the time period in the time period.
In step 1043, a fitting expression of the capacity variation tendency of the storage battery is set.
Wherein the fitting expression comprises unknown constant parameters. The fitting expression may be set according to the general variation tendency of the time period and the general variation tendency of the power supply time period. The fitting expression can also be set according to the working scene of the communication network where the storage battery is located. The setting manner of the fitting expression is not limited herein.
In step 1044, the capacity variation trend of the storage battery is obtained through fitting according to the power supply duration, the time period and the fitting expression.
In one example, according to the power supply duration, the time period and the fitting expression, the value of the unknown constant parameter in the fitting expression can be calculated through a fitting algorithm. Thereby obtaining a fitting expression in which a constant parameter capable of expressing the capacity variation tendency of the storage battery is known.
For example, fig. 4 is a schematic diagram illustrating a corresponding relationship between a power supply duration and time in another embodiment of the present invention. As shown in fig. 4, the power supply time period of each of 1 to 12 months can be obtained with a time period of 1 month. The solid curve is a power supply time length curve of each month actually recorded, and the dotted curve is a fitted power supply time length curve of each month. And the expression corresponding to the dotted curve is a fitting expression capable of expressing the capacity change trend of the storage battery.
The actual power supply time of each month can be counted in a form of a table, and a fitting expression capable of expressing the capacity variation trend of the storage battery is obtained by using data recorded in the table. For example, table one is a table of power supply durations of several months in 2015 years.
Watch 1
According to the power supply time period of 2 months to 4 months in table one, a fitting expression of the capacity variation tendency of the storage battery may be set to Y ═ a + bX + c/X, Y is the power supply time period, X is the time (month in this example), and a, b, and c are constant parameters. When the fitting expression is set, three constant parameters of a, b, and c are unknown. The monthly average power supply time length of 2 months, the monthly average power supply time length of 3 months and the monthly average power supply time length of 4 months can be substituted into the fitting expression, so that the values of the three constant parameters of a, b and c are obtained. Through calculation, a ═ 1270, b ═ 68, and c ═ 300 can be obtained. That is, the fitting expression capable of expressing the capacity variation tendency of the storage battery is Y1270 to 68X 300/X.
It should be noted that, before the capacity change trend of the storage battery supplying power to the alarm network element is obtained according to the generation time of the power supply alarm event and the generation time of the communication interruption alarm event, some power supply alarm events and target communication interruption alarm events having an interference effect may be excluded, so as to improve the accuracy of the generation time of the power supply alarm event and the generation time of the target communication interruption alarm event required for obtaining the capacity change trend of the storage battery.
In one example, power alarm events that occur with a third interval duration between the generation time and the end time that is less than the end duration threshold are excluded, as well as target communication disruption alarm events that occur with a third interval duration that is less than the end duration threshold. And the generation time of the power supply alarm event is the time when the original power supply of the alarm network element stops supplying power to the alarm network element. And the ending time of the power supply alarm event is the time for restoring the original power supply of the alarm network element to supply power to the alarm network element. The generation time of the target communication interruption alarm event is the time of communication interruption between the alarm network element and the adjacent network element. And the end time of the target communication interruption alarm event is the time for communication recovery between the alarm network element and the adjacent network element.
The ending duration threshold may be determined empirically and according to a specific working scenario, and is not limited herein. For example, the end duration threshold is set to ten minutes. And eliminating the power supply alarm event and the target communication interruption alarm event of which the third interval duration is less than the end duration threshold, thereby eliminating the influence of the flash alarm on the capacity analysis of the storage battery.
In another example, power source alarm events with a fourth interval duration between the generation time and the reporting time greater than the reporting duration threshold and target communication interruption alarm events with the fourth interval duration greater than the reporting duration threshold are excluded. After the power supply alarm event and the target communication interruption alarm event are generated, the power supply alarm event and the target communication interruption alarm event need to be reported. If the fourth interval duration between the generation time and the reporting time is greater than the reporting time threshold, the generation time of the power alarm event and/or the target communication interruption alarm event may not be accurate.
The reporting duration threshold may be determined according to experience and a specific working scenario, and is not limited herein. For example, the reporting duration threshold is set to fifteen minutes. And eliminating the power supply alarm event and the target communication interruption alarm event of which the fourth interval duration is greater than the reporting duration threshold, thereby eliminating the influence of inaccurate alarm time of the network element on the capacity analysis of the storage battery.
In yet another example, power source alarm events having a fifth interval duration between the current generation time and the last generation time that is less than the standard charge duration are excluded, and target communication disruption alarm events having a fifth interval duration that is less than the standard charge duration. After the battery is discharged, the battery also needs to be charged. When the charging of the storage battery is not completed, secondary discharging may be performed, and the power supply time period corresponding to the secondary discharging when the charging of the storage battery is not completed has a certain influence on the capacity analysis of the storage battery.
For example, if the fifth interval duration between the generation time of the third power alarm event and the generation time of the second power alarm event is less than the standard charging duration, the third power alarm event may be excluded.
The standard charging period is a period required for charging the battery until the capacity of the battery is reached. And eliminating the power supply alarm event and the target communication interruption alarm event of which the fifth interval duration is less than the standard charging duration, and eliminating the influence on the capacity analysis of the storage battery due to the occurrence of secondary discharge after the storage battery is not charged.
The three examples described above may also be combined with each other, and are not limited herein.
Fig. 5 is a flowchart of a method for analyzing the capacity of a battery according to another embodiment of the present invention. Fig. 5 is different from fig. 1 in that the battery capacity analysis method further includes step 105 and step 106.
In step 105, the capacity of the storage battery at a certain time is predicted from the capacity change tendency of the storage battery.
For example, according to the generation time of the power source alarm event and the generation time of the target communication interruption alarm information in the period from 1 month to 4 months in 2017 and the power supply time period in the period from 1 month to 4 months in 2017, the obtained fitting expression capable of expressing the capacity variation trend of the storage battery is that Y is 1270-68X-300/X. The power supply period of the battery from 5 months to 12 months in 2017 can be predicted. The power supply time period Y of the storage battery of 6 months is predicted to be 1270-68 multiplied by 6-300/6-812 minutes.
In step 106, if the predicted capacity of the storage battery is lower than a preset safety threshold, warning information is sent out.
The early warning information prompts that the capacity of the storage battery of a worker, an operator or a user is lower than a preset safety threshold value. And if the predicted capacity of the storage battery is lower than a preset safety threshold, replacing the storage battery, or carrying out charge-discharge test on the storage battery to recover the capacity of the storage battery.
Such as: the predicted power supply time period of the battery for 6 months is 812 minutes, and the predicted power supply time period of the battery for 11 months is 530 minutes. If the preset safety threshold is 700 minutes, early warning information can be sent out to prompt that the capacity of the storage battery is lower than the preset safety threshold in 11 months. It is also possible to trigger a charge-discharge test or replacement of the accumulator at 11 months.
It should be noted that, in an example, the capacity of the storage battery may be analyzed for each network element in the communication network, so as to obtain a capacity variation trend of the storage battery. And predicting the number of the storage batteries with the power supply duration being lower than the preset safety threshold. In order to verify the actual capacity of the accumulator with the predicted power supply duration lower than a preset safety threshold. The same number of battery capacity testers as the number of the batteries of which the predicted power supply duration is lower than the preset safety threshold may be provided. And monitoring the storage battery with the predicted power supply duration being lower than a preset safety threshold without monitoring the storage battery of each network element. The number of the battery capacity tester and the labor cost for installing the battery capacity tester are reduced.
