[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. 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.

[0030] Figure 1 This is the architecture diagram of the real-time monitoring and early warning system used in this embodiment. Figure 1 As shown, the system includes a dynamic environment system layer, a network device layer, a device management layer and an early warning layer.

[0031] The network device layer is used to realize network connection and transmission, and may include multiple network devices and network device resources. The network device resources are used to record the identification and distribution of different network devices, as well as the connection relationship between different network devices, the connection relationship between network devices and dynamic environment systems, etc. For example, the network device may be an access station device, which is usually a device for accessing the Internet, such as a base station, or an aggregation station device, that is, a transmission device of an access station device, such as a hub, switch, bridge, router, gateway, modem, optical fiber transceiver, etc.; Figure 1 FIG. 1 schematically shows a plurality of base stations, which are manufactured by different manufacturers, such as Huawei, ZTE, and Nortel. Further, Figure 1 The base station resources are shown to describe the distribution of base stations and the connection relationship between base stations and dynamic environment systems.

[0032] Among them, the dynamic environment system layer is used to monitor the operating environment of network devices and provide power for network devices. It can include multiple dynamic environment systems and dynamic environment resources. A dynamic environment system is used to monitor the operating environment and power equipment of one or more network devices. Figure 1It is shown that a dynamic environment system monitors two base stations; for example, the dynamic environment system may include a variety of power equipment such as switching power supplies, distribution boxes, batteries, and oil engines, as well as monitoring equipment such as sensors for monitoring various parameters of the computer room environment such as door magnets, infrared, broken windows, water immersion, temperature and humidity, and smoke sensors. The specific needs are determined according to the actual operating environment of the network equipment to which it is connected, and this embodiment does not make specific restrictions on this. For the sake of ease of description and distinction, the switching power supply, distribution box, battery, and oil engine are referred to as power supply and distribution systems below. Among them, the dynamic environment resources are used to record the number and distribution of different dynamic environment systems, as well as the connection relationship between the dynamic environment system and network equipment.

[0033] It should be noted that the battery in this embodiment can be understood as a single battery or a plurality of batteries, i.e., a battery pack, and is generally understood as all batteries in the dynamic ring system. In practical applications, the dynamic ring system either supplies power to the access station device or to the aggregation station device, and will not supply power to both the access station device and the aggregation station device at the same time.

[0034] In one example, Figures 2 to 3 The power supply process of the network equipment is shown. When the mains power supply is normal, the mains power supplies the network equipment through the distribution box and the switching power supply. When the mains power is cut off, the battery is used for emergency power supply, and the battery supplies power to the network equipment through the switching power supply. Furthermore, when the network equipment is an access station equipment, such as a base station, when the mains power is cut off, it is necessary to start the oil generator before the emergency power supply of the battery ends. After the oil generator is turned on, it can supply power to the access station equipment through the distribution box and the switching power supply.

[0035] For further information, please refer to Figures 2 to 4 , when the city power is cut off, the city power monitoring meter (for example, a smart meter) will detect the power outage and generate a city power outage alarm; the switch power supply will generate an AC input fault alarm. In addition, when the network device is a gathering station device, the distribution box will generate an input power-off alarm. When the switch power supply is cut off, the switch power supply will generate a first-level low-voltage disconnection warning, that is, a one-time power-off alarm. For example, when the city power is cut off and the battery is exhausted, the switch power supply will be cut off. Further, when the network device is an access station device, when the power supply to the access station device is stopped, the access station device is powered off and no longer works, and an equipment power-off warning is generated, such as a base station decommissioning alarm. For example, after the city power is cut off, the battery will stop supplying power to the access station device after the emergency power supply is completed, and an equipment decommissioning alarm is generated. When the network device is a gathering station device, since the gathering station device is usually not powered off, it usually does not generate an equipment power-off alarm, such as an equipment decommissioning alarm. When the city power is cut off and the battery power is low, the battery will generate a low voltage warning. These warnings will be reported to the equipment management layer.

[0036] The device management layer is used to monitor network devices and dynamic environment systems, and receive various warning information reported, which can include several network management systems and several dynamic environment monitoring systems. The network management system is used to monitor, test, configure, analyze, evaluate and control several connected network devices, to ensure that the network can operate normally and efficiently, and to make better use of resources in the network. In actual applications, different network management systems belong to different manufacturers, that is, different manufacturers will have their own network management systems; Figure 1 The figure shows Huawei network management, ZTE network management, dynamic environment network management, and Nortel network management. The dynamic environment monitoring system is used to record and analyze the monitoring data reported by several connected dynamic environment systems to diagnose and handle faults.

[0037] Furthermore, the equipment management layer may also include an integrated management system, wherein the integrated management system is used to manage the quantity, distribution, and connection status of all network devices and dynamic environment systems, usually including dynamic environment resources and network equipment resources. For the sake of ease of description and distinction, the dynamic environment resources and network equipment resources are referred to as spatial information to illustrate the connection relationship between network devices and dynamic environment systems.

[0038] It should be noted that the dynamic environment monitoring system will report the alarm information of the dynamic environment system (the time, equipment, content, etc. of the alarm) to the early warning layer. The network management system will report the alarm information of the network equipment (the time, equipment, content, etc. of the alarm) to the early warning layer. For the convenience of distinction and description, the alarm information of the dynamic environment system is called dynamic environment alarm information, and the alarm information of the network equipment is called network alarm information.

[0039] For example, the dynamic environment alarm information may indicate several alarms including the mains power failure alarm of the mains monitoring meter, the low voltage warning of the battery, the primary power failure alarm of the switching power supply, the AC input failure alarm of the switching power supply, the input power failure alarm of the distribution box, etc. The network alarm information may indicate the equipment out-of-service alarm.

[0040] Among them, the early warning layer is used to obtain the dynamic environment alarm information reported by the dynamic environment monitoring system, the network alarm information reported by the network equipment, and the spatial information reported by the integrated management system in real time, and determine the battery life values ​​of multiple dynamic environment systems in real time based on the spatial information, dynamic environment alarm information and network alarm information, so as to realize the battery life of massive monitoring batteries. For each dynamic environment system, the battery life capacity is analyzed based on the multiple battery life values ​​finally determined, and the health of the battery is determined or whether a battery health warning is needed, so as to quickly formulate the optimal power generation guarantee plan, effectively solve the problem of insufficient pertinence of power guarantee, and at the same time, the operation and maintenance personnel can also expand and reduce the capacity of the battery in a more timely manner.

[0041] In one example, the early warning layer may include a fault management system, which is used to interface with the device management layer to obtain dynamic environment alarm information, network alarm information, and spatial information in real time, so as to determine the battery life value of each of the multiple dynamic environment systems in real time. Figure 1 It is shown that the fault management system is connected to the network management of different manufacturers respectively, so as to obtain the dynamic environment alarm information reported by the dynamic environment monitoring system and the network alarm information reported by the network management system, and further, it is connected to the integrated management system to obtain the spatial information between the dynamic environment system and the network equipment. In one example, the fault management system may include a large database to store the dynamic environment alarm information, network alarm information, and spatial information between the dynamic environment system and the network equipment reported by the equipment management layer. It may also include a resource analysis association module, which is used to associate the battery in the dynamic environment system and several network devices powered by the dynamic environment system through the spatial information between the dynamic environment system and the network equipment.

[0042] In one example, the early warning layer may also include an intelligent notification system. Figure 3 The EMOS (Enterprise Maintenance and Operation Management) system shown is used to connect with the fault management system and obtain the battery life value from the fault management system. On the one hand, the EMOS system can combine the internally stored maintenance personnel to reach the diesel engine's road time value, automatically calculate the diesel engine power generation notification delay, and quickly formulate the optimal power generation guarantee plan, effectively solving the problem of insufficient targeted power guarantee. Figure 3 It shows that the EMOS system sends a work order / text message (notification information) to the maintenance personnel so that the maintenance personnel can start the oil engine before the emergency power supply of the battery ends. The oil engine supplies power to the network equipment through the distribution box and the switching power supply. On the other hand, the EMOS system can combine the initial battery life value stored internally and the multiple battery life values ​​finally determined to analyze the change in the battery's battery life and determine the health of the battery, so that the operation and maintenance personnel can also expand or reduce the capacity of the battery in a more timely manner.

[0043] like Figure 5 As shown, a method for determining the battery life provided by this embodiment is provided. The method provided by this embodiment can be applied to electronic devices, and can be specifically applied to servers or general computers. In this embodiment, the method specifically includes the following steps:

[0044] Step 501: determine the spatial information between multiple network devices and multiple power supply and distribution systems in the target area, where the spatial information indicates the network devices connected to each of the multiple power supply and distribution systems. Each of the multiple power supply and distribution systems includes a battery, and the battery supplies power to the connected network devices after the city power is cut off.

[0045] In one example, the spatial information is the connection relationship between multiple power supply and distribution systems and multiple network devices in the target area. Furthermore, the several network devices connected to the power supply and distribution system can be determined by the spatial information, and it should be understood that the several network devices connected to the power supply and distribution system are devices powered by the power supply and distribution system. It should be noted that in one possible case, the electronic device can obtain the spatial information between the multiple power supply and distribution systems and the multiple network devices from a device that stores the spatial information between the multiple power supply and distribution systems and the multiple network devices. For example, the spatial information between the multiple power supply and distribution systems and the multiple network devices can be stored by an integrated management system. Among them, the integrated management system is mentioned above and will not be elaborated here.

[0046] In one example, the target area may be an area where a power supply and distribution system and network equipment exist. For example, the target area may be a city or a province, which needs to be determined in combination with actual conditions.

[0047] In one example, the multiple network devices and multiple power supply and distribution systems may be all network devices and power supply and distribution systems in the target area, or may be the power supply and distribution system where the battery that needs to be monitored in the target area is located, and the network devices connected to the power supply and distribution system. The specific needs need to be determined in combination with actual needs, and will not be described in detail here. It is worth noting that the multiple network devices are usually network devices powered by multiple power supply and distribution systems.

[0048] In one example, for each of the multiple power supply and distribution systems, the power supply and distribution system is used to supply power to a number of connected network devices. For example, the power supply and distribution system includes a battery, a distribution box, a switching power supply, and a motor. The mains power supplies power to a number of connected network devices through the distribution box and the switching power supply; after the mains power is cut off, the battery supplies power to a number of connected network devices through the switching power supply. Ideally, before the battery is exhausted, the oil engine is turned on, and the oil engine generates power to supply power to a number of connected network devices through the distribution box and the switching power supply.

[0049] Step 502: Collect first alarm information; wherein the first alarm information at least indicates an alarm of partial or complete power outage in a plurality of power supply and distribution systems.

[0050] As a feasible implementation manner, the first alarm information at least indicates an alarm of a partial or complete power outage in each of the multiple power supply and distribution systems.

[0051] It should be noted that the first alarm information is used to indicate the alarm of the mains power outage within the preset time before the current moment, and not every power supply and distribution system will generate the mains power outage alarm. In addition, the first alarm information is collected by at least one dynamic environment monitoring system, and at least one dynamic environment monitoring system is used to monitor multiple power supply and distribution systems. In practical applications, for each of the multiple power supply and distribution systems, if the mains power is cut off, the mains monitoring meter will detect the power outage and generate a mains power outage alarm; the switching power supply will generate an AC input fault alarm; the distribution box will generate an input power outage alarm; when the battery power is low, the battery will generate a low voltage alarm; when the battery power is exhausted, the switching power supply will generate a first-level low voltage disconnection warning, that is, a power-off alarm; after that, the power supply and distribution system will report the generated alarm information (for example, the time, content, equipment, etc. of the alarm) to the dynamic environment monitoring system. The electronic device obtains the first alarm information from the dynamic environment monitoring system. In some possible cases, the power supply and distribution system will report the generated alarm information directly to the electronic device.

[0052] In one example, the first alarm information indicates an alarm of a mains power outage in some or all of the multiple power supply and distribution systems.

[0053] For example, for multiple power supply and distribution systems, multiple mains power outage alarms of the power supply and distribution systems may be detected in sequence according to a preset mains power outage alarm detection sequence, and the first detected alarm may be used as the final mains power outage alarm.

[0054] For example, when the network device is an access station device, the preset mains power failure alarm detection sequence may be the mains power failure alarm of the mains monitoring meter and the AC input fault alarm of the switching power supply. When the network device is an aggregation station device, the preset mains power failure alarm detection sequence may be the input power failure alarm of the distribution box, the mains power failure alarm of the mains monitoring meter, and the AC input fault alarm of the switching power supply. Correspondingly, the mains power failure alarm of some or all of the multiple power supply and distribution systems indicated by the first alarm information may be the mains power failure alarm of the mains monitoring meter, the input power failure alarm of the distribution box, or the AC input fault alarm of the switching power supply.

[0055] For example, the first alarm information indicates the collected alarms of mains power failure of some or all of the multiple power supply and distribution systems, ie, the preset mains power failure alarm detection order is not considered.

[0056] For example, if the network device connected to the power supply and distribution system is an access station device, the alarms of mains power failure of some or all systems in the multiple power supply and distribution systems indicated by the first alarm information include mains power failure alarms generated by mains monitoring meters and / or AC input failure alarms generated by switching power supplies. For details, see the above description and Figure 2-Figure 4 .

[0057] For example, if the network device connected to the power supply and distribution system is a convergence station device, the first alarm information indicates that the mains power failure alarms of some or all systems in the multiple power supply and distribution systems include the mains power failure alarm generated by the mains monitoring meter, the AC input fault alarm generated by the switching power supply, and / or the input power failure alarm generated by the distribution box. For details, please refer to the above description and Figure 2-Figure 4 .

[0058] Furthermore, the first alarm information also indicates an alarm of battery exhaustion of some or all of the multiple power supply and distribution systems, such as a power-off alarm generated by a switching power supply. In one example, for a power supply and distribution system that generates an alarm of battery exhaustion, several network devices connected to the power supply and distribution system are all access station devices, and the electronic device has not collected an alarm of power failure of the access station device. At this time, the first alarm information may indicate an alarm of battery exhaustion of the power supply and distribution system.

[0059] Furthermore, the first alarm information also indicates the low battery alarm of some or all of the multiple power supply and distribution systems, such as the low voltage alarm generated by the battery. In one example, for the power supply and distribution system that generates the low battery alarm, several network devices connected to the power supply and distribution system are all aggregation station devices. It should be noted that the aggregation station equipment is usually not powered off, so the low battery alarm is mainly considered. By way of example, the first alarm information can be the above-mentioned dynamic ring alarm information.

[0060] Step 503: collect second alarm information; wherein the second alarm information indicates an alarm that some or all of the multiple network devices are powered off.

[0061] As a feasible implementation manner, the second alarm information at least indicates an alarm that some or all of the multiple network devices are powered off.

[0062] It should be noted that the second alarm information can be understood as an alarm of power failure of network devices within a preset time before the current moment, such as an alarm of equipment decommissioning. Not every network device will generate an alarm of power failure. In addition, the second alarm information is collected by at least one network management system, and at least one network management system is used to monitor multiple network devices. Usually, different manufacturers each have a network management system for managing multiple network devices produced by them. For example, the second alarm information can be the above-mentioned network alarm information. In practical applications, for each of the multiple power supply and distribution systems, when the battery power is exhausted, several network devices connected to the system are powered off, and correspondingly, these network devices will generate an alarm of power failure, such as an alarm of equipment decommissioning; afterwards, these network devices will report the information of the alarm of power failure generated by each device (such as the time of occurrence, content, device, etc. of the alarm) to the network management system. The electronic device obtains the second alarm information from the network management system. In some possible cases, the network device will report the information of the generated device power failure alarm directly to the electronic device.

[0063] Step 504: Based on the spatial information, the first alarm information, and the second alarm information, determine the battery life values ​​of the respective batteries of some or all of the power supply and distribution systems in the plurality of power supply and distribution systems.

[0064] As a feasible implementation method, the battery life is determined by the following implementation method:

[0065] Based on the spatial information, the first alarm information and the second alarm information, multiple third alarm information are determined; wherein the multiple third alarm information respectively correspond one-to-one to all or part of the multiple power supply and distribution systems, the third alarm information includes the information of the alarm of the AC power outage of the corresponding power supply and distribution system in the first alarm information and the information of the alarm of the equipment power outage of the network equipment connected to the corresponding power supply and distribution system in the second alarm information, the occurrence time of the AC power outage alarm is earlier than the occurrence time of the equipment power outage alarm, and the time difference between the occurrence time of the AC power outage alarm and the occurrence time of the equipment power outage alarm is within the preset battery life threshold; for any one of the multiple third alarm information, based on the third alarm information, the battery life value of the battery in the corresponding power supply and distribution system is determined.

[0066] It should be noted that the third alarm information at least includes the occurrence time of the alarm used to calculate the battery life. In actual applications, the third alarm information includes the information in the first alarm information corresponding to the alarm of the mains power outage of the power supply and distribution system and the information in the second alarm information corresponding to the alarm of the power outage of each of the several network devices connected to the power supply and distribution system. Corresponding to the third alarm information, the occurrence time of the mains power outage alarm is earlier than the time of the device power outage, and the time difference between the occurrence time of the mains power outage alarm and the time of the device power outage is within the preset battery life threshold.

[0067] In an example, the network devices connected to the multiple power supply and distribution systems corresponding to the third alarm information are all access station devices.

[0068] In one example, the battery life is determined by the time difference between the mains power outage time and the device power outage time. For example, the mains power outage time is determined based on the time when the mains power outage alarm indicated by the third alarm information is generated. For example, there are multiple mains power outage alarms indicated by the third alarm information. In one implementation, the mains power outage alarm time is the average of the time when each mains power outage alarm occurs; in another implementation, the mains power outage alarm time is the time corresponding to the alarm that is ranked first after sorting multiple mains power outage alarms according to a preset mains power outage alarm detection order. For the preset mains power outage alarm detection order, please refer to the above, and no further elaboration will be given here.

[0069] For example, the device power-off time is determined based on the time when the device power-off alarm indicated by the third alarm information is generated. For example, the device power-off time is the average time when each device power-off alarm is generated; for another example, the device power-off time is the time when the earliest device power-off alarm generated in the third alarm information is generated.

[0070] In actual applications, the alarm of the mains power outage of the power supply and distribution system and the alarm of the power outage of the network equipment connected to the power supply and distribution system will be associated together, and the battery life value of the power supply and distribution system can be calculated based on the occurrence time of the associated alarms. For example, a main alarm (an alarm indicating that the battery is exhausted or the battery is low) and a secondary alarm (an alarm indicating that the mains power is off) can be set, and the battery life value of the battery can be determined based on the occurrence time of the main alarm and the occurrence time of the secondary alarm. It should be noted that, considering that the actual situation is more complicated, there may be a situation where the alarm information collection fails, so the detection order of multiple alarms of the secondary alarm is set to ensure that it can accurately determine whether the mains power is off. It should be understood that the time difference between the occurrence time of the main alarm and the secondary alarm should be within a certain period of time, and the length of the period needs to be determined in combination with the battery life value, for example, 10 hours.

[0071] For example, if the network device is an access station device and the access station device is a base station, then based on the association between the base station decommissioning alarm and the AC power outage alarm of the power supply and distribution system connected to the base station, the duration of the AC power outage alarm and the base station decommissioning alarm is analyzed in real time, which is the battery life value of the power distribution system.

[0072]

[0073]

[0074] Table 1

[0075] Priority: The AC power failure alarm of the monitoring meter > the AC input failure alarm of the switching power supply.

[0076] For example, considering that the battery may supply power to multiple base stations at the same time, the out-of-service alarms of multiple base stations powered by the battery are integrated according to time, and the most recent one is selected as the main alarm. Finally, only one out-of-service relationship is retained, and the most recent "mains power failure alarm" of the smart meter within 10 hours of the site is associated. If the association is not successful, the "AC input fault alarm" of the switching power supply is associated, and the calculated time difference is used as the battery life value. Then the battery life value of the base station dynamic ring battery = the occurrence time S1 of the base station out-of-service alarm - the occurrence time S0 of the mains power failure alarm or the occurrence time S2 of the AC input fault alarm (the most recent one within 10 hours).

[0077] As a feasible implementation, the first alarm information also indicates an alarm of exhaustion of battery power or low battery power of some or all of the multiple power supply and distribution systems, and the battery life can be determined by the following implementation:

[0078] Based on the spatial information, the first alarm information and the second alarm information, multiple four alarm information are determined; wherein, the multiple fourth alarm information respectively correspond one-to-one to all or part of the multiple power supply and distribution systems, the second alarm information does not indicate the alarm of power failure of equipment in the power supply and distribution systems to which the multiple fourth alarm information respectively correspond, the fourth alarm information indicates the occurrence time of the AC power failure alarm and the battery exhaustion alarm or the battery low power alarm, the occurrence time of the AC power failure alarm is earlier than the occurrence time of the battery exhaustion alarm or the battery low power alarm, and the time difference between the occurrence time of the AC power failure alarm and the occurrence time of the battery exhaustion alarm or the battery low power alarm is within the preset battery life threshold; for any alarm information among the multiple fourth alarm information, based on the fourth alarm information, the battery life value of the battery in the corresponding power supply and distribution system is determined.

[0079] For a power supply and distribution system that does not have an alarm of equipment power outage, the fourth alarm information can be directly determined. It should be noted that the fourth alarm information at least includes the occurrence time of the alarm used to calculate the battery life. In practical applications, the fourth alarm information includes the alarm information of the power supply and distribution system corresponding to the mains power outage in the first alarm information, as well as the alarm information of low battery power or exhausted battery power. Here, for the fourth alarm information, the occurrence time of the mains power outage alarm is earlier than the occurrence time of the low battery power or exhausted battery alarm, and the time difference between the occurrence time of the mains power outage alarm and the occurrence time of the low battery power or exhausted battery alarm is within the preset battery life threshold.

[0080] In one example, the battery life is determined based on the time difference between the mains outage time and the battery exhaustion time, wherein the mains outage time and the battery exhaustion time are determined based on the fourth warning information.

[0081] For example, the method for determining the mains power failure time is as described above, and will not be described in detail here. The battery power exhaustion time is the time when the battery power exhaustion alarm indicated by the fourth alarm information occurs.

[0082] For example, the network equipment is an access station equipment, and the "one power failure alarm" of the switch power supply is used as the main alarm, which is linked to the most recent city power failure warning of the site within 10 hours.

[0083] Main alarm One power off alarm Second warning (mains power outage) Monitoring of the mains power failure alarm of the electric meter / AC input failure alarm of the switching power supply Association conditions When a power failure alarm occurs, it is associated with the most recent power failure alarm within 10 hours. Related time 10 hours

[0084] Table 2

[0085] Priority: The AC power failure alarm of the monitoring meter > the AC input failure alarm of the switching power supply.

[0086] For example, the main alarm is the "first-level low voltage disconnection warning" of the switching power supply, and the "mains power failure" of the smart meter at the site within 10 hours is associated. If the association fails, the "AC input fault alarm" of the switching power supply is associated, and the calculated time difference is used as the battery life value. Then the battery life value = the occurrence time S3 of the first-level low voltage disconnection warning - the occurrence time S0 of the mains power failure alarm or the occurrence time S2 of the AC input fault alarm (the most recent one within 10 hours).

[0087] In one example, the battery life is determined based on the time difference between the mains outage time and the battery low power time, wherein the mains outage time and the battery low power time are determined based on the fourth warning information.

[0088] For example, the mains power outage time is as mentioned above, and no further details are given here. The low battery time is the time when the low battery alarm indicated by the fourth alarm information occurs.

[0089] For example, the network equipment is a gathering station equipment, and the main alarm is the "total voltage too low alarm" of the battery group, which is linked to the most recent warning of city power outage within 10 hours at the site.

[0090]

[0091] Table 3

[0092] Priority: Input power failure alarm of the distribution box > Mains power failure alarm of the monitoring meter > AC input failure alarm of the switching power supply.

[0093] For example, the "low voltage warning" of the battery is associated with the "input power failure alarm" of the distribution box at the site within 10 hours. If there is no such alarm, the "mains power failure" of the smart meter and the "AC input fault alarm" of the switch power supply are associated in sequence. Then the battery life value = the occurrence time S4 ​​of the low voltage warning of the battery - the occurrence time S0 of the mains power failure or the AC input fault alarm S2 (the most recent one within 10 hours).

[0094] In practical applications, the above steps 501 to 504 may be performed periodically to continuously determine the battery life values ​​of multiple power supply and distribution systems.

[0095] Furthermore, some or all of the multiple power supply and distribution systems include oil generators. For any power supply and distribution system including oil generators, after the city power is cut off, the maintenance personnel will start the motor and supply power to the network equipment through the distribution box and the switch power supply. Considering that the function of the oil generator is to supply power before the battery is exhausted, and the oil generator needs to be turned on by the maintenance personnel before it can supply power, the oil generator power supply can be realized by the following implementation method:

[0096] Obtain the time it takes for the operation and maintenance personnel to reach the oil generator; automatically calculate the oil generator power generation notification delay based on the time it takes and in combination with multiple endurance values; and send the oil generator power generation notification information to the operation and maintenance personnel based on the oil generator power generation notification delay.

[0097] For example, a standard endurance value of multiple endurance values ​​can be calculated, and the difference between the standard endurance value and the journey time value can be used as the generator power generation delay value. The method for determining the standard endurance value is described below. For another example, the difference between the last determined endurance value and the journey time value can be used as the generator power generation delay value.

[0098] For example, if the delay of the oil generator power generation notification message is 2 hours, the operation and maintenance personnel need to be notified within 2 hours. If the operation and maintenance personnel do not take action, the oil generator power generation notification message can be sent continuously, or the importance of the message can be continuously upgraded.

[0099] Furthermore, for each of the multiple power supply and distribution systems, the health of the battery in the power supply and distribution system is determined based on multiple endurance duration values ​​of the battery in the power supply and distribution system before the current moment.

[0100] Health: A value used to evaluate the health status of a battery, used to measure whether the storage capacity of the battery is normal. For example, a health of 0 indicates unhealthy, and a health of 1 indicates healthy. For example, the health can be described by words such as unhealthy or low health. For example, the health can be a probability value of health, or a health degree value.

[0101] As a feasible implementation method, for any of the multiple power supply and distribution systems, an abnormal value check is performed on the multiple battery life values ​​finally determined, and the abnormal values ​​in the multiple battery life values ​​are eliminated to obtain multiple normal battery lifes; the standard battery life is determined based on the multiple normal battery lifes; based on the standard battery life value and the finally determined battery life values, the health of the battery in the power supply and distribution system is determined.

[0102] It should be understood that in order to ensure that the reference battery life value can be determined more accurately, it is necessary to detect abnormal values ​​of multiple battery life values ​​and eliminate occasional abnormal values. For example, for the same battery, for the last multiple battery life values ​​determined continuously, sort the multiple battery life values ​​in order from late to early, determine the time series, and start from the last position of the time series. The difference between the two battery life values ​​adjacent in time is calculated in sequence. If the ratio of the later battery life value to the earlier battery life value is greater than the preset threshold, such as 1.2, then the later battery life value can be considered to be an abnormal value, and the later battery life can be directly deleted; for example, if the battery life value determined for the Nth time> the battery life determined for the N-1th time*(1+20%), then the battery life value determined for the Nth time is eliminated. In addition, if the number of normal battery life values ​​is small, the previous battery life values ​​can be detected until a specified number of normal battery life values ​​are determined.

[0103] In one example, when the ratio of the last determined battery life among multiple battery lifes to the standard battery life value is less than a preset threshold value, such as 0.8, the battery can be considered unhealthy, and the health can be described by words such as unhealthy or low health.

[0104] In one example, the ratio of the last determined battery life among the multiple battery life values ​​to the standard battery life is used as the health level.

[0105] In one example, the average of multiple normal battery life values ​​can be used as the standard battery life value. Alternatively, the value obtained by weighted average of multiple normal battery life values ​​can be used as the standard battery life value. For example, the earlier the determination time is, the smaller the weight is.

[0106] In one example, the standard battery life can be determined based on multiple normal battery lifes by the following implementation:

[0107] For each of the multiple normal battery life values, based on the time difference between the time when the normal battery life value is determined and the current time, the battery life value is predicted based on the time difference and the battery life value to determine the predicted battery life value; based on the predicted battery life value corresponding to each of the multiple normal battery life values, the standard battery life value in the power supply and distribution system is determined.

[0108] First, a prediction function can be constructed to represent the change between the battery life and time in the power supply and distribution system. The function uses the initial battery life as a constant, the battery life at a certain moment, the period from the time when the battery life is determined to the current moment as independent variables, and the current battery life as the dependent variable. Then, for each of the multiple battery life values, the time difference between the time when the battery life value is determined and the current moment is determined, and then the battery life value and the time difference value are substituted into the prediction function to obtain the predicted battery life. Finally, these predicted battery life are weighted averaged or averaged to determine the standard battery life. In addition, the predicted battery life can also be tested for outliers, and weighted averaged or averaged after removing the outliers.

[0109] As a feasible implementation method, the health of the battery in the power supply and distribution system can be determined by the following implementation method:

[0110] Determine the number of AC power outage alarms, wherein the number of AC power outage alarms indicates the number of AC power outage alarms of the power supply and distribution system before the current moment; Determine the number of battery early warnings, wherein the number of battery early warnings indicates the number of battery exhaustion or low battery alarms of the power supply and distribution system before the current moment; Determine the health of the batteries in the power supply and distribution system based on the initial battery life value, multiple battery life values, the number of AC power outage alarms, and the number of battery early warnings.

[0111] In practical applications, outliers among multiple battery life values ​​can also be eliminated.

[0112] First, the number of mains outage alarms can be determined, which can be used to roughly infer the number of times the battery has been powered. Then, the number of battery alarms can be determined, which can be used to roughly infer the number of times the battery has been exhausted or has a low charge.

[0113] The dynamic environment system includes an oil engine. When the oil engine is supplying power, if the battery power is not exhausted or is not lower than the preset low power threshold, no warning of battery exhaustion or low power will be issued. In practical applications, the oil engine power generation time is determined, and the emergency duration of the battery is determined based on the time difference between the oil engine power generation time and the main power outage time (the main power outage time is before the oil engine power generation time, and the time difference between the main power outage time and the oil engine power generation time is within the preset endurance threshold); further, the battery usage time is determined based on multiple emergency times of the battery before the current time and multiple endurance times of the battery.

[0114] Finally, the health of the battery is determined based on the number of mains power outage alarms, the number of battery warnings, the battery usage time, and multiple battery life times. For example, when the number of mains power outage alarms, the number of battery warnings, and the total battery usage time are large, the health is low. When the number of mains power outage alarms, the number of battery warnings, and the battery usage time are small, the health is high.

[0115] For example, multiple samples can be determined, and each sample carries a label indicating whether it is healthy, including the number of mains power outage alarms before a certain moment, the number of battery warnings, the total battery usage time, the last multiple battery life times determined (continuous in time, and outliers can also be excluded), and the initial battery life time; the analysis model can be trained based on multiple samples to obtain a trained model. The health of the battery is determined based on the trained analysis model. For example, the analysis model can be a logistic regression model or a neural network model, which can be determined based on actual needs.

[0116] As a feasible implementation method, the health of the battery in the power supply and distribution system can be determined by the following implementation method:

[0117] Perform an outlier test on multiple battery life values, eliminate outliers from the multiple battery life values ​​to obtain multiple normal battery life values; fit the multiple normal battery life values ​​based on their respective determination moments to obtain a first curve corresponding to the multiple normal battery life values; determine a second curve of the battery in the power supply and distribution system, the second curve indicating a changing trend of the battery life over time; based on the second curve, determine whether the changing trend of the first curve is consistent with the changing trend of the battery life, and if not, determine that the battery in the power supply and distribution system is unhealthy.

[0118] In practical applications, when it is judged that the health of the batteries in the power supply and distribution system is low or unhealthy, a health warning can be issued for the batteries in the dynamic environment system.

[0119] Furthermore, for each of the multiple power supply and distribution systems, the battery life value of the power supply and distribution system is analyzed based on a preset warning mechanism to determine whether a health warning is required for the battery in the power supply and distribution system.

[0120] As a feasible implementation method, the preset warning mechanism includes N times of meeting the same-month warning conditions and / or loss warning conditions for the first warning; wherein N is a positive integer greater than or equal to 1, the same-month warning rule includes the ratio between the last two determined battery life values ​​meeting the first preset threshold, the streaming warning condition includes the ratio between the last determined battery life and the standard battery life meeting the second preset threshold, and the standard battery life is determined based on the last determined multiple battery life values. The method for determining the standard battery life value is described above, and no further elaboration will be given here.

[0121] In practical applications, an early warning mechanism combining the same-month-on-month early warning condition and the streaming early warning condition can be used to specify multiple early warning triggering schemes. When the early warning is triggered, the battery can be considered scrapped, and an alarm message is generated to notify relevant personnel to replace the battery. Among them, the streaming early warning condition can be understood as the ratio between the battery life value and the standard battery life value determined last to meet the preset threshold, for example, the battery life value determined last is less than 80% of the standard battery life value. The same-month-on-month early warning condition can be understood as the same-month / month-on-month calculation result of the battery life value within a period of time exceeds the increase / decrease range specified by the strategy, and the same-month comparison means the comparison between the current period and the previous period, such as the comparison between April this year and April last year; the month-on-month comparison means the comparison between the current period and the previous period, such as the comparison between April this year and March this year. This embodiment adopts the same-month result, for example, the ratio of the last determined battery life to the second last determined battery life is greater than 120%, or less than 80%.

[0122] In practical applications, for any of the multiple power supply and distribution systems, it is continuously determined whether the same-month and month-on-month warning conditions and / or loss warning conditions are met, and a health warning is implemented based on the warning mechanism.

[0123] In one example, the early warning mechanism is to meet the loss early warning conditions. The early warning can be implemented in the following ways:

[0124] Determine an alarm threshold based on a standard endurance value; determine a first comparison result between the last determined endurance value and the alarm threshold; and determine whether a health warning is required for the battery in the power supply and distribution system based on the first comparison result.

[0125] For example, the alarm threshold may be 80% of the standard endurance value, for example, when the first comparison result is that the last determined endurance value is less than 80% of the standard endurance value, it is necessary to issue a health warning to the battery in the power supply and distribution system. Otherwise, it is not necessary.

[0126] In one example, the early warning mechanism is to meet the same period last year and the same period last year early warning conditions. The early warning can be implemented in the following ways:

[0127] Determine a second comparison result; wherein the second comparison result is a result of comparison between the last two determined battery life values ​​among the multiple battery life values; based on the second comparison result, determine whether it is necessary to issue a health warning for the battery in the power supply and distribution system.

[0128] For example, if the second comparison result is that the ratio between the last determined endurance value and the second to last determined endurance value is greater than a preset threshold value such as 1.2, or less than a preset threshold value such as 0.8, then a health warning of the battery in the power supply and distribution system needs to be issued. Otherwise, no warning is required.

[0129] In one example, the early warning mechanism satisfies both the same-month-on-month early warning conditions and the streaming early warning conditions.

[0130] For example, if the first comparison result is that the last determined endurance value is less than the alarm threshold, and the second comparison result is that the ratio between the last determined endurance value and the second-to-last determined endurance value is greater than a preset threshold value such as 1.2, or is less than a preset threshold value such as 0.8, then it is necessary to issue a health warning for the battery in the power supply and distribution system. Otherwise, it is not necessary.

[0131] In one example, the warning mechanism is to meet the same period last year and the same period last year warning conditions and / or the streaming warning conditions for multiple consecutive times.

[0132] For example, when the first comparison results of three consecutive monitorings are all that the last determined endurance value is less than the alarm threshold, it is necessary to issue a health warning for the battery in the power supply and distribution system. Otherwise, it is not necessary. It should be noted that the alarm threshold is re-determined for each monitoring, so the alarm threshold is constantly changing based on the standard endurance value.

[0133] For example, when the first comparison results of three consecutive monitorings are that the last determined endurance value is less than the alarm threshold, and the second comparison result is that the ratio between the last determined endurance value and the second-to-last determined endurance value is greater than a preset threshold value such as 1.2, or less than a preset threshold value such as 0.8, then it is necessary to issue a health warning for the battery in the power supply and distribution system. Otherwise, it is not necessary.

[0134] Furthermore, the preset warning mechanism also includes: performing a second warning when the same period warning condition and / or the loss warning condition are met M times; wherein M is a positive integer greater than or equal to N, and the level of the first warning is less than the level of the second warning. Alternatively, the preset warning mechanism also includes: performing a step-by-step warning based on the number of first warnings.

[0135] It should be noted that the step warning can be understood as setting different warning levels according to different situations, such as ordinary warning, important warning, severe warning, etc. For example, for a battery, if the number of warnings is greater than or equal to 3 times and less than 5 times, an ordinary warning is generated, if the number of warnings is greater than or equal to 5 times and less than 10 times, an important warning is generated; if the number of warnings is greater than or equal to 10 times, a severe warning is generated. For example, the number of warnings is the number of consecutive warnings. For example, for a battery, if the battery life value of each of the three consecutive monitoring times of the battery is less than the standard battery life value of the battery * 80%, an ordinary warning is generated, if the battery life value of each of the five consecutive monitoring times of the battery is less than the standard battery life value of the battery * 80%, an important warning is generated, and if the battery life value of each of the ten consecutive monitoring times of the battery is less than the standard battery life value of the battery * 80%, a severe warning is generated.

[0136] Furthermore, the warning mechanism can also be a step warning for the target area based on the number of health warnings for the batteries in all power supply and distribution systems. Alternatively, the step warning for the area can be based on the number of health warnings for the batteries in multiple power supply and distribution systems in some areas of the target area.

[0137] In actual applications, the optimal battery protection plan can be quickly formulated based on the standard battery life value and the actual battery life value, and the protection plan can be notified to the operation and maintenance personnel, making the battery update and scrapping work more timely and targeted. Furthermore, the battery life values ​​of all dynamic and environmental systems in the target area can be automatically analyzed to generate a battery life analysis report for the target area. The target area can be a city, a province, etc.

[0138] Through the above technical solution, it can be seen that the beneficial effects of this embodiment are:

[0139] This embodiment realizes automatic analysis of the battery life, monitors the changes in the battery life of a large number of batteries in real time, and intelligently determines the standard battery life value through analysis of historical battery life values, intelligently detects inefficient batteries and issues real-time warnings, and guides operation and maintenance personnel to replace batteries in a timely manner to avoid business interruptions caused by insufficient battery life.
