[0001] The present invention relates to the technical field of power supply monitoring and analysis, and in particular to a communication power supply status monitoring method and system. Background Art

[0002] In the field of communications, the stable operation of communication power supply is very important. Communication power supply is usually composed of multiple batteries, and its performance directly affects the normal operation of communication equipment. With the continuous development of communication technology and the widespread application of communication equipment, higher requirements are placed on the accuracy and reliability of communication power supply status monitoring.

[0003] The patent application with publication number CN116593927A discloses a method and device for monitoring the power status of a communication device. The method includes: monitoring the input voltage of the main power module, and the method includes: identifying the power-off and power-on of the main power module according to the input voltage; determining the power supply logic of the disk according to the power-off and power-on of the main power module; if the power supply logic of the disk is abnormal, finding the boundary position between normal power supply logic and abnormal power supply logic, and restarting the secondary power module at the boundary position. The present invention infers whether the power supply logic of the disk is abnormal through the power-off and power-on of the main power module, and finds the boundary position where the logic abnormality occurs, so that only the power module at the boundary position where the power supply logic abnormality occurs is processed, avoiding the overall restart of the disk, thereby accelerating the recovery of the normal power supply logic of the disk and shortening the recovery time after service interruption.

[0004] However, traditional communication power status monitoring methods often have certain limitations. The judgment of battery status is not accurate enough, it is difficult to detect potential problems in advance, and it is impossible to accurately predict battery life. As a result, when the communication power fails, it may affect the normal development of communication services, causing economic losses and reduced user experience. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a communication power supply status monitoring method and system, which solves the problem that the judgment of the battery status is not accurate enough, it is difficult to discover potential problems in advance, and the battery life cannot be accurately predicted, which may affect the normal development of communication services when the communication power fails.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a communication power supply status monitoring method, the method specifically comprising the following steps: Step 1, obtain the basic information of the communication power supply, and mark the communication power supply according to the basic information; Step 2: Analyze the charging and discharging states of the communication power supply separately, and obtain the abnormal state batteries in the communication power supply based on the consistency of the charging and discharging process; Step 3, obtain the historical charge and discharge records corresponding to the abnormal state battery, calculate the battery abnormal value corresponding to the abnormal state battery, and compare the battery abnormal value with the preset value to generate a comparison signal; Step 4: Analyze the generated comparison signal, and predict the battery life of the battery in abnormal state according to the battery analysis signal, and generate corresponding monitoring cycle information based on historical data.

[0007] As a further solution of the present invention, the specific method of Step 1 for marking the communication power supply according to the basic information is: Basic information is obtained, and the basic information includes the power supply quantity, battery voltage, battery current, battery temperature and battery capacity corresponding to the communication power supply. At the same time, the obtained batteries are labeled as i, and i=1, 2, ..., j, where j represents the number of batteries.

[0008] As a further solution of the present invention, the specific method of analyzing the charging state of the communication power supply in Step 2 is: If constant voltage charging is used, the charging voltage of battery i is obtained. If the current decreases slowly within the time period t after reaching the constant voltage value, it is normal. Otherwise, if the current decreases too fast compared to the normal value, it is marked as an abnormal battery. For constant current charging, the charging current of battery i is obtained. If the current is constant and the voltage gradually rises to normal, no processing is done. If the voltage rises too slowly or too quickly compared to the normal value, it is marked as an abnormal battery, and the normal value is set by the operator.

[0009] As a further solution of the present invention, the specific method of analyzing the discharge state of the communication power supply in Step 2 is: During constant current discharge, if the voltage drops at a uniform rate, it indicates that the battery is in normal condition; if the voltage drops too quickly or too slowly, it is marked as an abnormal battery, and the fast or slow drop is judged based on the normal value, where the specific value of the normal value is set by the operator.

[0010] During constant voltage discharge, if the terminal voltage drops much faster than normal, or the starting current far exceeds the normal range, or the temperature during discharge exceeds the normal working range, if any of the above situations occurs, it indicates that the battery state is abnormal and it will be marked as an abnormal battery.

[0011] As a further solution of the present invention, the specific method of obtaining the abnormal state battery in the communication power supply by integrating the consistency of the charging and discharging process in Step 2 is: The charging and discharging processes corresponding to all batteries are obtained. If any process is abnormal, the corresponding battery is marked as an abnormal battery. Otherwise, if the charging and discharging processes are normal, the corresponding battery is marked as a normal battery.

[0012] As a further solution of the present invention, the specific method of generating the comparison signal in Step 3 is: S31. Obtain all abnormal state batteries and label them as n, where n=1, 2, ..., m, where m is the number of abnormal state batteries. Then obtain the historical charge and discharge records corresponding to the abnormal state battery n, and simultaneously obtain the cycle number Cn, the over-discharge and over-charge number Ln, and the storage capacity value Kn in the historical charge and discharge records, and substitute the obtained parameters into the formula The battery abnormality value Qn corresponding to the abnormal state battery n is calculated, and Ln is the sum of the over-discharge times and the over-charge times; S32. Compare the obtained battery abnormality value Qn with the preset value Qy, and the specific value of the preset value Qy is set by the operator. If the battery abnormality value Qn is greater than the preset value Qy, a battery warning signal is generated. Conversely, if the battery abnormality value Qn is less than the preset value Qy, a battery analysis signal is generated.

[0013] As a further solution of the present invention, the specific method of analyzing the generated comparison signal in Step 4 is: S41, obtaining a comparison signal, and directly displaying the corresponding abnormal state battery information to the corresponding operator for the battery warning signal in the comparison signal, obtaining the corresponding abnormal state battery as the battery to be analyzed for the battery analysis signal, and predicting the battery life by establishing a mathematical model of battery capacity attenuation; S42. The empirical model is determined through a large number of experiments, and the battery life C is calculated according to the formula C=C0×(1-k×N), where k is the capacity attenuation coefficient, C0 is the initial capacity of the battery, and N is the number of battery charge and discharge cycles; S43, then obtain historical data, and at the same time obtain the storage capacity of the battery to be analyzed in different time periods T, and calculate the time interval corresponding to the change in storage capacity, and so on, sum up all time intervals and calculate the average to obtain the interval mean, then obtain the number of charge and discharge cycles and the number of uses corresponding to the battery to be analyzed, and calculate the ratio of the two as the cycle proportion value, and at the same time substitute the obtained parameters into the formula monitoring period = interval mean + [(1-cycle proportion value) × interval mean], and obtain the monitoring period of the battery to be analyzed through the formula calculation, and generate monitoring period information.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a step method diagram of the present invention; Figure 2 This is a block diagram of the system principle of the present invention. DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] For example, see Figure 1The present application provides a communication power supply status monitoring method, which specifically includes the following steps: Step 1: Obtain the basic information of the communication power supply, and mark the communication power supply according to the basic information.

[0019] The basic information includes the number of power supplies corresponding to the communication power supply, battery voltage, battery current, battery temperature and battery capacity. Under normal circumstances, the communication power supply is composed of multiple batteries. At the same time, the obtained batteries are labeled and recorded as i, and i=1, 2, ..., j, where j represents the number of batteries.

[0020] Number of power supplies: Clarify the actual number of power supply devices in the communication power supply system. For example, in a medium-sized communication base station, there may be two main power supply devices to ensure the stability and reliability of power supply.

[0021] Battery voltage: refers to the potential difference between the two ends of a single battery. It is one of the important indicators reflecting the working status of the battery. Different types of batteries have different normal voltage ranges. For example, the normal voltage range of a common lead-acid battery is around 2V, while the nominal voltage of a lithium-ion battery is generally 3.7V.

[0022] Battery current: includes charging current and discharging current. By monitoring the current, we can understand the charging and discharging status of the battery and the load conditions. For example, when charging, if the charging current is too small, it may mean that the charging equipment is faulty or there is a problem with the battery; when discharging, if the current is too large, it may mean that the load is too heavy.

[0023] Battery temperature: The battery will generate heat during operation, and its temperature will affect the performance and life of the battery. Generally speaking, the normal operating temperature range of the battery is between 20℃-40℃. For example, when the temperature exceeds 45℃, the chemical reaction inside the battery will accelerate, which may shorten the battery life.

[0024] Battery capacity: represents the amount of charge that a battery can store, usually measured in ampere-hours (Ah). For example, the capacity of a battery is 100Ah, which means that under certain discharge conditions, the battery can be discharged continuously at a current of 1A for 100 hours.

[0025] Step 2: Analyze the charging and discharging states of the communication power supply separately, and obtain the abnormal state batteries in the communication power supply based on the consistency of the charging and discharging process.

[0026] All batteries i are obtained, and then they are analyzed from two aspects: battery charging state and battery discharging state.

[0027] S1. Analyze the battery charging state: There are two situations for the battery charging state, namely constant voltage charging and constant current charging; S11. During the constant voltage charging process, the voltage value of the battery i during the charging process needs to be obtained in real time. When the voltage rises to the set constant voltage value, the current will gradually decrease. Here, the current change within the time period t (for example, t=10 minutes) is used as the basis for judgment. If the current decrease is less than a certain proportion (such as 10%) within the t time, it means that the current decreases slowly. This may mean that the battery is not fully charged, or the battery capacity is large, which is within the normal range; if the current decrease exceeds a certain proportion (such as 50%) within the t time, it means that the current decreases too fast. At this time, the battery may be fully charged, or there may be a battery failure that cannot continue to absorb charge. Such corresponding batteries should be marked as abnormal batteries. For example, a battery is set to a constant voltage value of 48V. After reaching this voltage, the initial current is 5A. The current drops to 4.6A within 10 minutes, with a decrease of 8%, which is normal; if the current drops to 2A within 10 minutes, with a decrease of 60%, it needs to be marked as abnormal.

[0028] S12. For the constant current charging mode, the current value of the battery i during the charging process is obtained. If the current remains constant and the voltage rises steadily, it indicates that the battery pack is in a normal constant current charging state. If the voltage rise rate is too slow, for example, the voltage rise is less than 0.5V within 1 hour, it may be that the charging current is too small, or the internal resistance of the battery increases due to aging; if the voltage rise rate is too fast, such as the voltage rises by more than 2V within 1 hour, it may be that the charging current is too large, or there is a problem inside the battery. Once the above situation occurs, the corresponding battery i needs to be marked as an abnormal battery.

[0029] S2. Analyze the battery discharge state: Similarly to the battery charging state, there are two situations in the discharge process, namely constant voltage discharge and constant current discharge; S21. During constant current discharge, the voltage will gradually decrease. If the voltage drops evenly, it means that the battery pack is in a normal discharge state. If the voltage drops too quickly, for example, the voltage drops by more than 0.8V within half an hour, it may be that the battery capacity is insufficient, the internal resistance is increased, or the load is too large. If the voltage drops too slowly, for example, the voltage drops by less than 0.2V within half an hour, it may be that the discharge current is too small or the battery is abnormal. As long as the voltage drops too quickly or too slowly, it means that the battery state is abnormal, and the corresponding battery should be marked as an abnormal battery.

[0030] S22. During constant voltage discharge, if the terminal voltage of the battery drops significantly faster than the normal level, for example, the terminal voltage drops by 0.3V per hour under normal circumstances, but it drops by more than 0.6V per hour at this time, it means that the battery capacity may have been greatly reduced, or there are serious faults such as plate short circuit and electrolyte leakage inside the battery. In addition, if the current is far beyond the normal range (such as the normal initial current is 3A, and it exceeds 5A at this time) in the initial stage of constant voltage discharge, and the battery temperature is too high during constant voltage discharge and exceeds the normal operating temperature range (assuming that the normal operating temperature range is 20℃-40℃, and the temperature exceeds 45℃ at this time), as long as any of the above conditions occurs, it indicates that the battery state is abnormal, and the corresponding battery needs to be marked as an abnormal battery.

[0031] S3. Obtain the charging and discharging processes corresponding to all batteries. If any process is abnormal, the corresponding battery is marked as an abnormal battery. Otherwise, if the charging and discharging processes are normal, the corresponding battery is marked as a normal battery.

[0032] Step 3, obtain the historical charge and discharge records corresponding to the abnormal state battery, calculate the battery abnormal value corresponding to the abnormal state battery, and compare the battery abnormal value with the preset value to generate a comparison signal.

[0033] S31. Obtain all abnormal state batteries and label them as n, and n=1, 2, ..., m, where m is the number of abnormal state batteries, then obtain the historical charge and discharge records corresponding to the abnormal state battery n, and at the same time obtain the cycle number Cn, over-discharge and over-charge number Ln and storage capacity value Kn in the historical charge and discharge records, where the cycle number represents the number of repetitions of the complete process of the battery from fully charged state to fully discharged state and then back to fully charged state, and over-discharge and over-discharge are judged from voltage and current respectively. Specifically for voltage judgment, each type of battery has its specific discharge termination voltage. When the battery voltage drops below this value, over-discharge may occur. During the charging process, when the battery voltage reaches its full charge voltage and continues to charge, the voltage will continue to rise. If the battery voltage exceeds its maximum allowable charging voltage, it can be judged as overcharge. For current judgment, during normal discharge, the current will gradually decrease as the battery power decreases. However, when the battery has been discharged to the end state, the current does not drop significantly, but fluctuates abnormally or continues to maintain a large value. This may be a manifestation of over-discharge of the battery. In the constant voltage charging stage, as the battery is close to full charge, the charging current should gradually decrease. If the current does not decrease after the battery voltage reaches the full charge voltage, but continues to maintain a large charging current, then the battery is likely to be in an overcharged state.

[0034] At the same time, substitute the obtained parameters into the formula The battery abnormality value Qn corresponding to the abnormal state battery n is calculated, and Ln here is the sum of the over-discharge times and the over-charge times; S32. Compare the obtained battery abnormality value Qn with the preset value Qy, and the specific value of the preset value Qy is set by the operator. If the battery abnormality value Qn is greater than the preset value Qy, a battery warning signal is generated. Conversely, if the battery abnormality value Qn is less than the preset value Qy, a battery analysis signal is generated.

[0035] Step 4: Analyze the generated comparison signal, and predict the battery life of the battery in abnormal state according to the battery analysis signal, and generate corresponding monitoring cycle information based on historical data.

[0036] S41, obtaining a comparison signal, and directly displaying the corresponding abnormal state battery information to the corresponding operator for the battery warning signal in the comparison signal, obtaining the corresponding abnormal state battery as the battery to be analyzed for the battery analysis signal, and predicting the battery life by establishing a mathematical model of battery capacity attenuation; S42. Determine the empirical model through a large number of experiments, and calculate the battery life C according to the formula C=C0×(1-k×N), where k is the capacity attenuation coefficient. Specifically, perform multiple charge and discharge cycle experiments on the battery, record the battery capacity data after each cycle, draw a capacity attenuation curve with the number of charge and discharge cycles as the horizontal axis and the ratio of the battery capacity to the initial capacity as the vertical axis, and then use a suitable mathematical function to fit the curve, C0 is the initial capacity of the battery, and N is the number of charge and discharge cycles of the battery; S43, then obtain historical data, and at the same time obtain the storage capacity of the battery to be analyzed in different time periods T, and calculate the time interval corresponding to the change in storage capacity, and so on, sum up all time intervals and calculate the average to obtain the interval mean, then obtain the number of charge and discharge cycles and the number of uses corresponding to the battery to be analyzed, and calculate the ratio of the two as the cycle proportion value, and the specific formula is number of cycles / number of uses, and at the same time substitute the obtained parameters into the formula monitoring period = interval mean + [(1-cycle proportion value) × interval mean], and obtain the monitoring period of the battery to be analyzed through the formula calculation, and generate monitoring period information.

[0037] For example, in the time period T1 = 1 month, the storage capacity is 500mAh, and in the time period T2 = 2 months, the storage capacity is 450mAh. The further calculation time interval is 1 month, and all time intervals are summed and the average is calculated to obtain the interval mean. Assuming that we have multiple sets of such time interval data, their sum is G, and the number is F, then the interval mean is G / F. At the same time, the corresponding number of cycles in the past period is 200 times, and the corresponding number of uses is 300 times. The calculated ratio of the two is 2 / 3. Further substitute the obtained parameters into the formula to calculate the value of the monitoring cycle is 2 months. From this, it can be known that the battery to be analyzed needs to be inspected and maintained every 2 months.

[0038] For example 2, please refer to Figure 2 The present application provides a communication power supply status monitoring system, including: a power supply information acquisition module, a power supply status analysis module, an abnormal status analysis module and an analysis information output module, and combined with Figure 2 It can be known that the above functional modules are electrically connected in a unidirectional manner.

The specific processing method is the same as the processing process of Step 2 in the first embodiment, and the abnormal state battery is transmitted to the abnormal state analysis module; An abnormal state analysis module, which is used to obtain the historical charge and discharge records corresponding to the abnormal state battery, and calculate the battery abnormal value corresponding to the abnormal state battery, and compare the battery abnormal value with the preset value to generate a comparison signal, and the comparison signal includes a battery warning signal and a battery analysis signal, and the specific processing method is the same as the processing process of Step 3 in Example 1, and the generated comparison signal is analyzed at the same time, and the battery life of the abnormal state battery is predicted according to the battery analysis signal, and the corresponding monitoring cycle information is generated according to the historical data, and the specific processing method is the same as the processing process of Step 3 in Example 1, and then the generated monitoring cycle information is transmitted to the analysis information output module; An analysis information output module is used to display the acquired monitoring cycle information to the corresponding operator.
