Description

Technical Field

[0001] The present application relates to the technical field of power supply switching, and in particular to a power supply switching method and electronic equipment for a triple backup power supply system. Background Art

[0002] The reliability of power supply is crucial to the normal operation of various devices and systems. The stability of power supply directly affects the normal operation of the system and the security of data. Therefore, the research on backup solutions and power switching methods for power systems has received increasing attention. Existing power management technologies can guarantee power supply to a certain extent, but there are still some obvious defects.

[0003] At present, the traditional single power supply configuration often has certain shortcomings and cannot provide sufficient power guarantee. In practical applications, the failure of the main power supply, the failure of the backup power supply to start in time, or the failure to support the normal operation of the system for a long time will lead to serious consequences such as equipment shutdown and data loss, which brings great risks to the stable operation of critical tasks. Therefore, in order to solve these problems, the traditional power guarantee system has gradually exposed some technical defects. First, the existing power supply system mostly relies on AC power and uninterruptible power supply (UPS), but in extreme cases, if the AC power and UPS power fail at the same time, the existing system often does not have enough emergency power to ensure the continuous operation of the equipment. Secondly, due to the lack of automatic switching mechanism in the implementation of the multi-backup power supply system, when multiple power supplies fail, manual intervention is relied on for switching, which not only increases the operation and maintenance costs, but also may delay the emergency response time and cannot guarantee the timely recovery of the system.

[0004] In summary, the prior art has a technical problem that due to the lack of an automatic switching mechanism, when both the mains power and the UPS power supply fail at the same time, the continuous operation of the equipment cannot be ensured, further affecting the stable operation of key tasks and data security.

[0014] This application solves the technical problem that the lack of an automatic switching mechanism in the prior art leads to the inability to ensure the continuous operation of equipment when both the mains power and the UPS power fail, further affecting the stable operation of key tasks and data security by providing a power supply switching method and electronic equipment for a three-backup power supply system. The technical goal of automatically switching power supplies to ensure the continuous operation of key equipment is achieved, and the technical effect of improving the stability of key tasks and data security is achieved.

[0015] Below, the technical solutions in the present application will be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments of the present application. It should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application. It should also be noted that, for the convenience of description, only the parts related to the present application are shown in the accompanying drawings, rather than all of them.

[0016] For example, please refer to the attached Figure 1 The present application provides a power supply switching method for a three-backup power supply system, which specifically includes the following steps: Step 1: Obtain the AC power supply, uninterruptible power supply, network switching equipment, dual backup centralized power supply and battery life in the three-backup power supply system of the target area, use the AC power supply as the main power supply, connect the network switching equipment through the main power supply to perform the main power supply configuration, obtain the main power supply connection, use the uninterruptible power supply as the first backup power supply, connect the network switching equipment through the first backup power supply to perform the first backup power supply configuration, and obtain the first backup power supply connection.

[0017] Specifically, the target area refers to a specific area where power supply continuity is ensured, such as a data center or industrial park. The three-backup power supply system in the target area includes a mains power supply, an uninterruptible power supply, a network switching device, a dual-backup centralized power supply, and a battery for endurance. The mains power supply is the power supply from the power grid, which serves as the main power supply of the three-backup power supply system and provides basic power.

[0018] Next, the AC power supply is used as the main power supply to directly supply power to the network switching device through the power line. The network switching device is used to connect data transmission between multiple devices. The main power supply configuration of the network switching device through the main power supply means connecting the AC power supply and the network switching device together, and ensuring that the mission equipment can operate normally when the AC power supply is stable through battery testing and charging parameter configuration.

[0019] If the mains fails, the uninterruptible power supply will be relied upon as a backup power source. An uninterruptible power supply (UPS) is a power supply device used to provide power supply for a short period of time. The network switching equipment is connected to the uninterruptible power supply for the first backup power supply configuration. The uninterruptible power supply is equipped with a battery that can be started immediately when the mains power fails, ensuring that the network switching equipment is not affected and continues to supply power to the mission equipment, ensuring that the equipment can continue to operate when the mains power fails.

[0020] Step 2: Supply power to the mission equipment in the target area through the main power supply connection, monitor the status of the main power supply connection, and obtain main power supply status monitoring results, wherein the main power supply status monitoring results include main power supply normal results and main power supply abnormal results.

[0021] Specifically, mission equipment refers to equipment that requires stable power supply in the target area, such as monitoring equipment, recording equipment, and video equipment. Through the main power supply connection, the main power source such as the mains will provide the necessary power for the mission equipment to ensure that the mission equipment can operate normally.

[0022] Next, the status of the main power supply connection is monitored when the main power supply is connected, that is, the power connection and its operating status are monitored and evaluated in real time to ensure the stability of the power supply and to detect potential power problems in a timely manner. If there are problems such as power outages or voltage fluctuations, the monitoring system will detect them in time and make adjustments or switch to backup power sources.

[0023] The status monitoring results of the main power supply are obtained through status monitoring. The status monitoring results are used to describe the working condition of the main power supply. The monitoring results include two results: the main power supply is normal and the main power supply is abnormal. If the main power supply is normal, it means that the main power supply is stable and the mission equipment can work normally; if the main power supply is abnormal, it means that there are power problems such as instability of the main power supply, which triggers the switching of the backup power supply.

[0024] Step three: Based on the main power supply abnormality result, the task equipment is supplied with power through the first backup power supply connection, and the status of the first backup power supply connection is monitored. If the first backup power supply abnormality result is obtained, the second backup power supply connection is enabled to supply power to the task equipment in combination with the main power supply abnormality result, wherein the second backup power supply connection uses the AC power supply or the uninterruptible power supply as the second backup power supply, and the second backup power supply is configured by connecting the second backup power supply to the dual backup centralized power supply.

[0025] Specifically, based on the main power supply abnormality results, it means that the main power supply may not be able to work normally due to voltage problems, power outages or other factors, and the main power supply fails or is unstable. In this case, it will automatically switch to the first backup power supply, that is, the uninterruptible power supply, and continue to provide the necessary power for the mission equipment through the first backup power supply connection.

[0026] Next, in order to ensure that the first backup power supply connection works stably, its status needs to be monitored. The status of the first backup power supply connection is monitored by checking the power supply status in real time to ensure that the backup power supply can provide power normally. If an abnormal result of the first backup power supply is obtained during the monitoring process, it means that there is also a problem with the first backup power supply, such as insufficient battery power or other faults that cause it to be unable to supply power normally.

[0027] At this time, in order to avoid power outages on mission equipment, the second backup power supply connection is enabled. The second backup power supply connection means that when the circuits connecting the main power supply and the first backup power supply to the network switching equipment are abnormal, the power supply is connected to the dual backup centralized power supply through the main power supply or uninterruptible power supply for power supply.

[0028] Finally, the second backup power supply configuration refers to the configuration of connecting the AC power supply or uninterruptible power supply to the dual backup centralized power supply to complete the switching of power supply, and then automatically switch when the circuit connecting the AC power supply or uninterruptible power supply to the network switching equipment fails, avoiding power supply interruption to the mission equipment.

[0029] Step 4: Monitor the status of the second backup power supply connection. If a second backup power supply abnormality result is obtained, enable the third backup power supply connection to supply power to the task equipment in combination with the main power supply abnormality result and the first backup power supply abnormality result, wherein the third backup power supply connection is obtained by configuring the third backup power supply with the endurance battery as the third backup power supply.

[0030] Specifically, the second backup power supply connection refers to connecting the dual backup centralized power supply through the mains power supply or uninterruptible power supply to provide power for the mission equipment. The status monitoring of the second backup power supply connection is to check the stability of the power supply in real time. If there is a problem with the second backup power supply connection, the monitoring system will detect and record the abnormal results.

[0031] Next, if an abnormal result is obtained for the second backup power supply, indicating that the circuit of the AC power supply or uninterruptible power supply connected to the dual backup centralized power supply in the second backup power supply connection cannot supply power normally, the third backup power supply connection is enabled to avoid power outages or shutdowns of the mission equipment and ensure the reliability of power supply.

[0032] The third backup power connection refers to the power provided by the endurance battery. The endurance battery is composed of lithium batteries that store energy and serves as the last layer of backup power. When the first two layers of backup power fail to work, the endurance battery will be enabled and directly provide power to the mission equipment, ensuring that the mission equipment can continue to operate even in extreme situations.

[0033] Step 5: When any connection state of the main power supply connection, the first backup power supply connection and the second backup power supply connection is restored, the third backup power supply connection is disabled.

[0034] Specifically, when any of the main power supply connection, the first backup power supply connection, or the second backup power supply connection is restored, it means that a backup power supply has restored its normal power supply capacity, and it automatically switches back to these power supplies, and the third backup power supply connection is disabled, that is, the power supply is restored to normal working state, and the mission equipment can rely on the main power supply or other backup power supplies again. The third backup power supply connection, as the last power guarantee, will only be enabled when other power supplies cannot supply power normally. When the previous power supply resumes power supply, the battery no longer needs to continue to provide power, so it is disconnected and the normal power supply is restored.

[0035] The power supply switching method for the three-backup power supply system can achieve the technical goal of automatically switching power supplies and ensuring the continuous operation of key equipment, thereby achieving the technical effect of improving the stability of key tasks and data security.

[0036] Furthermore, the present application also includes: the AC power supply and the uninterruptible power supply are connected in parallel to the three-backup power supply system, connected to the network switching equipment and the dual backup centralized power supply, and supply power to the task equipment.

[0037] Specifically, the mains power supply and the uninterruptible power supply are connected in parallel to the three-backup power supply system. The mains power supply refers to the power obtained from the public power grid, which provides stable AC power. The uninterruptible power supply (UPS power supply) is a backup power supply to ensure that it can continue to supply power when the mains power fails. By connecting in parallel, the mains power supply and the uninterruptible power supply can jointly provide power for the mission equipment. Among them, the mains power supply provides power as the main power supply, and the uninterruptible power supply automatically takes over when the mains power fails.

[0038] Next, the AC power supply and the uninterruptible power supply are connected to the network switching equipment and the dual backup centralized power supply respectively, that is, the AC power supply is connected to the network switching equipment and the dual backup centralized power supply at the same time, and the uninterruptible power supply is connected to the network switching equipment and the dual backup centralized power supply at the same time. Network switching equipment refers to equipment used for data transmission and network connection, which requires stable power support to ensure smooth data communication. Dual backup centralized power supply refers to a power supply system with dual inputs (such as AC power supply and uninterruptible power supply), which can switch to the working state according to the status of the power input to ensure that the equipment is continuously supplied with power. Connect the AC power supply and the uninterruptible power supply to ensure that there will be no power interruption when the mission equipment switches between different power sources.

[0039] Furthermore, the present application also includes: using the AC power supply as the high-level backup power supply in the second backup power supply, connecting the dual backup centralized power supplies through the high-level backup power supply to perform high-level backup power supply configuration, and obtaining a high-level backup power supply connection; monitoring the status of the high-level backup power supply connection, and if a high-level backup power supply abnormality result is obtained, analyzing whether there is a power supply abnormality result of the AC power supply status monitoring in the main power supply abnormality result or the high-level backup power supply abnormality result; if so, using the uninterruptible power supply as the low-level backup power supply in the second backup power supply, configuring a low-level backup power supply through the low-level backup power supply and the dual backup centralized power supplies to obtain a low-level backup power supply connection; monitoring the status of the low-level backup power supply connection to obtain a low-level backup power supply status monitoring result, adding the high-level backup power supply abnormality result and the low-level backup power supply status monitoring result to the second backup power supply status monitoring result, and combining the high-level backup power supply connection and the low-level backup power supply connection to obtain the second backup power supply connection.

[0040] Specifically, the mains power supply is the senior backup power supply in the second backup power supply, which means that the mains power supply has a higher priority in connection with the dual backup centralized power supply. At the same time, the uninterruptible power supply is the junior backup power supply in the second backup power supply, which means that the uninterruptible power supply has a lower priority in connection with the dual backup centralized power supply. That is, the dual backup centralized power supply has a priority in connection with the mains power supply.

[0041] Advanced backup power supply configuration is performed by connecting the AC power supply to the dual backup centralized power supply. Through battery testing and charging parameter configuration, power can be provided to the mission equipment. Status monitoring is performed on the advanced backup power supply connection to check whether the advanced backup power supply can work normally and ensure stable power supply. If an advanced backup power supply abnormality result is obtained, it means that the advanced backup power supply cannot supply power normally. Further analysis of the advanced backup power supply abnormality result shows that the cause of the abnormality is the abnormal power supply of the AC power supply. Among them, when the cause of the abnormality in the main power supply abnormality result is the abnormal power supply of the AC power supply, directly connect the dual backup centralized power supply through the uninterruptible power supply to power the mission equipment.

[0042] If the cause of the abnormality in the power supply abnormality result of the mains power supply is the power supply abnormality of the mains power supply, the uninterruptible power supply is enabled as the low-level backup power supply in the second backup power supply. The uninterruptible power supply will be connected to the dual backup centralized power supply and supply power to the task equipment.

[0043] Next, the status of the low-level backup power supply connection is monitored to ensure the stability of the low-level backup power supply and the continuity of power supply, and the low-level backup power supply status monitoring results are obtained. Among them, the second backup power supply status monitoring results include the high-level backup power supply status monitoring results and the low-level backup power supply status monitoring results, the high-level backup power supply status monitoring results include the high-level backup power supply normal results and the high-level backup power supply abnormal results, and the low-level backup power supply status monitoring results include the low-level backup power supply normal results and the low-level backup power supply abnormal results. Through the second backup power supply connection, the continuous power supply of the mission equipment is guaranteed through multi-level backup power supplies.

[0044] Furthermore, the present application also includes: when there is a power supply abnormality result of the AC power supply status monitoring in the main power supply abnormality result or the second backup power supply abnormality result of the second backup power supply status monitoring result, and at the same time there is a power supply abnormality result of the uninterruptible power supply status monitoring in the first backup power supply abnormality result or the second backup power supply abnormality result, the third backup power supply connection is enabled to supply power to the task equipment.

[0045] Specifically, when there is a power supply abnormality result of the main power supply abnormality result or the second backup power supply abnormality result in the second backup power supply status monitoring result, it means that the main power supply cannot work normally and cannot provide power. At the same time, if there is a power supply abnormality result of the uninterruptible power supply status monitoring in the first backup power supply abnormality result or the second backup power supply abnormality result, it means that the uninterruptible power supply cannot work normally either.

[0046] If both the mains power supply and the uninterruptible power supply are abnormal, the third backup power connection is activated to provide power for the mission equipment. The third backup power connection refers to the battery pack, generator and other endurance batteries to power the mission equipment. The endurance battery will only be activated when all other power sources fail, ensuring that the mission equipment can continue to work even if all regular power sources fail.

[0047] Furthermore, the present application also includes: when the status monitoring of the mains power supply and / or the uninterruptible power supply shows that the power supply is normal, the power supply output of the battery life battery is disabled to complete the deactivation of the third backup power supply connection.

[0048] Specifically, when the status monitoring of the AC power supply or uninterruptible power supply or both the AC power supply and the uninterruptible power supply shows a normal power supply result, that is, when the status of either the AC power supply or the uninterruptible power supply is restored, it means that these power supply systems are working stably and can provide continuous power to the mission equipment.

[0049] Next, disabling the power output of the battery means no longer using the battery to provide power. The battery usually provides backup power when the main power supply and uninterruptible power supply have problems. Therefore, after the main power or uninterruptible power supply returns to normal, the power output of the battery will be suspended to avoid unnecessary battery consumption.

[0050] Furthermore, the present application also includes: when the state monitoring of the mains power supply shows that the power supply is normal, the mains power supply is used to input power to the battery life battery.

[0051] Specifically, when the status monitoring of the AC power supply shows that the power supply is normal, it means that the AC power supply is running stably and can provide continuous power. For example, the output voltage, current and other parameters of the AC power supply are within the normal working range, and there are no power interruptions or abnormalities. At this time, the battery life battery is powered by the AC power supply, and the power is transmitted to the battery life battery through the AC power supply to charge the battery life battery, ensuring that the battery life battery still has enough power to support the operation of the equipment when the main power supply fails. The battery life battery is usually used as a backup power supply, which can provide continuous power supply to the equipment when the AC power supply or other backup power supply fails.

[0052] Furthermore, the present application also includes: using the battery life battery as the third backup power supply to perform a third backup power supply configuration in a first connection mode to obtain a first connection mode of the third backup power supply connection; using the battery life battery as the third backup power supply, connecting the third backup power supply to a dual backup centralized power supply to perform a third backup power supply configuration in a second connection mode to obtain a second connection mode of the third backup power supply connection; combining the first connection mode and the second connection mode to obtain the third backup power supply connection.

[0053] Specifically, the battery life battery is used as the third backup power source, directly connected to the task equipment for power supply configuration, and power supply is performed. The connection method of directly connecting the battery life battery to the task equipment is used as the first connection method.

[0054] Next, the battery life battery is connected to the dual backup centralized power supply for power supply configuration and power supply. The battery life battery is connected to the dual backup centralized power supply and the connection method for powering the task equipment is used as the second connection method. Then, when the dual backup centralized power supply fails, the task equipment can be directly powered by the battery life battery.

[0055] Finally, the first connection method and the second connection method are combined as the third backup power supply connection to ensure stable backup power supply under different connection methods and ensure that the mission equipment can still operate normally when problems occur in the main power supply and backup power supply.

[0056] To summarize, the power supply switching method for a three-backup power supply system provided in the present application has the following technical effects: by obtaining the AC power supply, uninterruptible power supply, network switching equipment, dual backup centralized power supply and endurance battery in the three-backup power supply system of the target area, the AC power supply is used as the main power supply, and the network switching equipment is connected through the main power supply to perform the main power supply configuration, and the main power supply connection is obtained; the uninterruptible power supply is used as the first backup power supply, and the network switching equipment is connected through the first backup power supply to perform the first backup power supply configuration, and the first backup power supply connection is obtained; the task equipment in the target area is supplied with power through the main power supply connection, and the status of the main power supply connection is monitored to obtain the main power supply status monitoring result, wherein the main power supply status monitoring result includes a main power supply normal result and a main power supply abnormal result; according to the main power supply abnormal result, the task equipment is supplied with power through the first backup power supply connection, and the status of the first backup power supply connection is monitored. If the first backup power supply is obtained, The power abnormality result is combined with the main power supply abnormality result to enable the second backup power supply connection to supply power to the task equipment, wherein the second backup power supply connection is to use the AC power supply or the uninterruptible power supply as the second backup power supply, and the second backup power supply is connected to the dual backup centralized power supply by the second backup power supply to perform the second backup power supply configuration; the status of the second backup power supply connection is monitored, and if the second backup power supply abnormality result is obtained, the third backup power supply connection is enabled to supply power to the task equipment in combination with the main power supply abnormality result and the first backup power supply abnormality result, wherein the third backup power supply connection is to use the battery life battery as the third backup power supply for the third backup power supply configuration; when any connection status of the main power supply connection, the first backup power supply connection and the second backup power supply connection is restored, the third backup power supply connection is disabled, that is, by achieving the technical goal of automatically switching power supplies to ensure the continuous operation of key equipment, the technical effect of improving the stability of key tasks and data security is achieved.
