[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0042] Example 1, please refer to Figure 1 As shown, the method for powering through a PoE power supply system described in this embodiment includes the following steps:

[0043] S1. Obtain device information of the PoE power supply system, wherein the device information includes power supply device information and powered device information, and establish a power supply distribution map based on the device information;

[0044] S2. Based on the power supply distribution diagram, the power supply device simulates power supply to the powered device to obtain the device state of the power supply device and the device state of the powered device, wherein the device state includes an unstable state and a stable state;

[0045] S3, optimizing the powered device based on the device status of the power supply device and the device status of the powered device to obtain a simulated power supply diagram;

[0046] S4, supplying power to the corresponding powered device from the power supply device based on the simulated power supply diagram, obtaining actual power consumption information of the powered device, wherein the actual power consumption information includes actual power consumption and corresponding duration period, and constructing a power consumption model according to the actual power consumption information;

[0047] S5. Obtain a power supply model of the power supply device based on the power consumption model of the power supply device corresponding to the powered device, and bind the power supply model with the corresponding power supply device to obtain a power supply control diagram;

[0048] As described in the above steps S1-S5, with the development of PoE technology, PoE power supply systems have been widely used in various devices that require networked power supply. The PoE power supply system includes two parts: a power supply device and a powered device. At present, the PoE power supply system does not clearly plan how the power supply device should power the corresponding powered device. When a powered device increases its power, other powered devices may be short of power and cause power outages. The powered devices are unstable during operation, and the power supply devices do not have good power supply coordination. The present application can maximize the use of the power supply power of the power supply device, reasonably plan the power supply sequence of the power supply device, and provide a backup power supply device for the powered device when the power supply device is insufficient and the powered device is about to be powered off, thereby ensuring the safety of the powered device and the stability of the power supply device, and having a good power supply coordination effect;

[0049] In one embodiment, the step S1 of establishing a power supply distribution map based on device information includes:

[0050] S11. Acquire power supply device information and powered device information of the PoE power supply system as device information, wherein the power supply device information includes device number, device location, maximum power supply power, interface priority, and device number connected to the interface, and the powered device information includes device number, device location, maximum power consumption, and device number of the corresponding power supply device;

[0051] S12, establishing an electronic map according to the device locations of the power supply device and the powered device, connecting the power supply device and the powered device with the corresponding device number in the electronic map and binding the corresponding device information to obtain a power supply distribution map;

[0052] As described in the above steps S11-S12, the main equipment of the PoE power supply system is the power supply equipment and the powered equipment. The power supply equipment here can be a PoE switch, a PoE injector, a PoE power supply, etc., and the powered equipment here can be an IP phone, a network camera, a wireless access point, etc., and the power supply equipment information and the powered equipment information in the PoE power supply system are obtained, wherein the power supply equipment information includes the equipment number, the equipment location, the maximum power supply power, the interface priority and the equipment number connected to the interface, and the powered equipment information includes the equipment number, the equipment location, the maximum power consumption and the equipment number corresponding to the power supply equipment, and the equipment number here corresponds to a power supply equipment Or the powered device, where the device location can get the distance relationship between the devices, the interface of the power supply device corresponds to the powered devices of different priorities, and the powered device also marks the power supply device to be connected, and then an electronic map is established according to the device location of the power supply device and the device location of the powered device. On the electronic map, the powered device finds the corresponding power supply device according to the device number of the corresponding power supply device, and the power supply device finds the corresponding interface according to the device number of the powered device. The powered device is connected to the corresponding interface of the power supply device and the device information is bound to the corresponding device to obtain a power supply distribution map, which can clearly and intuitively show the connection and distribution relationship between the powered device and the power supply device;

[0053] In one embodiment, the step S2 of simulating power supply of the powered device to the powered device based on the power supply distribution diagram to obtain the device state of the powered device and the device state of the powered device includes:

[0054] S21, the power supply device performs simulated power supply to the powered devices of the corresponding interfaces in descending order according to the interface priorities according to the maximum power;

[0055] S22, calculating the remaining simulated power supply of the power supply device, where the remaining simulated power supply is the difference between the maximum power supply of the power supply device and the maximum power consumption of the corresponding powered device. If the maximum power consumption of the powered device is greater than or equal to the remaining simulated power supply, the power supply device and the corresponding powered device are marked as unstable. If the maximum power consumption of the powered device is less than the remaining simulated power supply, the power supply device and the corresponding powered device are marked as stable.

[0056] As described in the above steps S21-S22, based on the power supply distribution diagram, the power supply device simulates power supply to the powered device of the corresponding interface in descending order according to the interface priority according to the maximum power, and calculates the remaining simulated power supply power, wherein the remaining simulated power supply power is the difference between the maximum power supply power of the power supply device and the maximum power consumption of the corresponding powered device. The state of the device is judged according to the remaining simulated power supply power. For example, the maximum power supply power of a power supply device is 30w, and there are three interface priorities, which are arranged from high to low, namely the first interface, the second interface, and the third interface, and the maximum power consumption of the corresponding powered devices is 12w, 10w, and 10w, after powering the second interface, the remaining simulated power supply power is insufficient to power the third interface, and the third interface may not be able to complete its device function due to insufficient power, or even be powered off, so the powered device corresponding to the third interface and the corresponding power supply device are marked as unstable. If the maximum power consumption of the powered device corresponding to the power supply device is 10w, 10w, and 5w respectively, the remaining simulated power supply power of the power supply device can meet the needs of all connected powered devices, so the power supply device and the corresponding powered device are in a stable state, and it is possible to predict whether the power supply device and the powered device are stable during operation based on the remaining simulated power supply power;

[0057] In one embodiment, the step S3 of optimizing the powered device based on the device state of the power supply device and the device state of the powered device to obtain a simulated power supply diagram includes:

[0058] S31, connecting a power supply device as an intermediate power supply device between the power supply device in an unstable state and the corresponding power receiving device in an unstable state, and using the power supply device corresponding to the power receiving device as the main power supply device;

[0059] S32, obtaining a stable power supply device which is closest to the intermediate power supply device and whose remaining simulated power supply power satisfies the maximum power consumption of the unstable power receiving device as a backup power supply device;

[0060] S33, connecting the standby power supply device to the low priority interface of the intermediate power supply device, and connecting the main power supply device to the high priority interface of the intermediate power supply device;

[0061] As described in the above steps S31-S33, power supply devices in an unstable state are collected in the power supply distribution map, and a power supply device is connected between the power supply device in an unstable state and the corresponding power receiving device in an unstable state as an intermediate power supply device, and the power supply device corresponding to the power receiving device is used as the main power supply device. The function of the intermediate power supply device here is to connect the power receiving device in an unstable state with the power supply device in an unstable state, and then a stable power supply device that is closest to the intermediate power supply device and whose remaining simulated power supply power meets the maximum power consumption of the power receiving device in an unstable state is obtained as a backup power supply device. For example, if the maximum power consumption of the power receiving device in an unstable state is 10w, if the remaining simulated power supply power of the power supply device closest to the intermediate power supply device is 15w and is in a stable state, it can be used as a backup power supply device. The backup power supply device is connected to the low-priority interface of the intermediate power supply device, and the main power supply device is connected to the high-priority interface of the intermediate power supply device, which can better ensure the safety and stability of power supply.

[0062] In one embodiment, the step S4 of constructing the power consumption model according to the actual power consumption information includes:

[0063] S41, the power supply device supplies power to the powered devices of the corresponding interfaces in descending order according to the interface priorities;

[0064] S42, obtaining the actual power consumption of the powered device, obtaining the time when the actual power consumption is running as the duration period, binding the actual power consumption with the corresponding duration period to obtain a power consumption model of the powered device, and binding the power consumption model with the corresponding powered device;

[0065] S43, calculating the remaining power supply of the power supply device, where the remaining power supply is the difference between the maximum power supply of the power supply device and the actual power consumption of the corresponding powered device, and marking the remaining power supply on the corresponding power supply device;

[0066] As described in the above steps S41-S43, the power supply device supplies power to the powered devices of the corresponding interfaces in order from high to low according to the interface priority. In different situations, the power consumption of the powered devices may be different. For example, a powered device such as a webcam only needs to provide a camera function during the day, and the power consumption is relatively low. However, at night, it needs to turn on infrared rays, LED lights and other functions, and the power consumption demand will be higher than the demand during the day. At night, low-priority powered devices may be underpowered. Therefore, it is necessary to regulate the powered devices according to the actual situation, collect the actual power consumption of the powered devices, collect the time when the actual power consumption is running as the duration period, bind the actual power consumption with the corresponding duration period to obtain the power consumption model of the powered devices, bind the power consumption model with the corresponding powered devices, and then calculate the remaining power supply of the power supply device. The remaining power supply is the difference between the maximum power supply of the power supply device and the actual power consumption of the corresponding powered device. This can better demonstrate the power consumption fluctuation of the powered devices during operation, and lay a foundation for subsequent operations.

[0067] In one embodiment, the step S5 of obtaining the power supply model of the power supply device based on the power consumption model of the power supply device corresponding to the powered device includes:

[0068] S51, obtaining power consumption models of multiple powered devices corresponding to the power supply device, combining and adding the actual power consumption of the multiple power consumption models corresponding to the multiple power consumption models based on the duration periods of the multiple power consumption models to obtain the actual power supply power of the power supply device, and binding the actual power supply power with the duration period to obtain the power supply model of the power supply device;

[0069] S52, binding the power supply model with the corresponding power supply equipment to obtain a power supply control diagram, and regulating the powered equipment corresponding to the power supply equipment according to the power supply control diagram;

[0070] As described in the above steps S51-S52, the power consumption models of the multiple power receiving devices corresponding to the power supply device are collected, and the actual power consumption of the corresponding multiple power consumption models is combined and added based on the duration of the multiple power consumption models to obtain the actual power supply power of the power supply device. For example, one power supply device corresponds to two power receiving devices, then they correspond to the first power consumption model and the second power consumption model respectively, wherein the power consumption of the first power consumption model is 15w from 0:00 to 6:00, the power consumption from 6:00 to 12:00 is 10w, the power consumption from 12:00 to 19:00 is 8w, and the power consumption from 19:00 to 0:00 is 12w, and the power consumption of the second power consumption model is 15w from 0:00 to 12:00 , the power consumption from 12 o'clock to 0 o'clock is 10w, and the time period from 0 o'clock to 6 o'clock is called the duration period, and then the first power consumption model is combined with the second power consumption model to obtain a power supply power of 30w from 0 o'clock to 6 o'clock, a power supply power of 25w from 6 o'clock to 12 o'clock, a power supply power of 18w from 12 o'clock to 19 o'clock, and a power supply power of 22w from 19 o'clock to 0 o'clock. A two-dimensional statistical chart with the horizontal axis as the power supply power and the vertical axis as the time period is made as the power supply model of the power supply equipment, and the power supply model is bound to the corresponding power supply equipment to obtain a power supply control chart. According to the power supply control chart, the corresponding power receiving equipment of the power supply equipment is regulated, and the power supply situation of the power supply equipment in each time period can be better monitored;

[0071] In one embodiment, the step S52 of regulating the powered device corresponding to the power supply device according to the power supply control diagram and the power supply model includes:

[0072] S521, monitor the actual power supply of the power supply equipment. When the actual power supply reaches the maximum power supply, shut down the interfaces of the power supply equipment in descending order of priority until the actual power supply can meet the actual power consumption of the high-priority powered device, shut down the high-priority interface of the intermediate power supply equipment, open the low-priority interface of the intermediate power supply equipment, and use the standby power supply equipment for power supply;

[0073] S522, when the remaining power supply meets the maximum power consumption of the low-priority powered device, the interfaces of the power supply devices are opened in descending order of priority until the remaining power supply does not meet the maximum power consumption of the powered device, the high-priority interface of the intermediate power supply device is opened, the low-priority interface of the intermediate power supply device is closed, and the main power supply device provides power;

[0074] As described in the above steps S521-S522, the actual power supply power of each power supply device is monitored according to the power supply control diagram and the power supply model. For example, the maximum power supply power of a power supply device is 30w, and the maximum power consumption of the power receiving devices corresponding to the four interfaces are sorted from high to low in priority as 15w for the first interface, 15w for the second interface, 10w for the third interface, and 5w for the fourth interface. The interfaces of the power supply device are shut down in order from low to high priority until the power supply power can meet the power consumption of the high-priority power receiving devices. For example, at 1 o'clock, the actual power consumption of the first interface is 12w, the actual power consumption of the second interface is 12w, the actual power consumption of the third interface is 8w, and the actual power consumption of the fourth interface is 3w. The actual power supply power reaches 35w, and the power supply device shuts down the third interface and the fourth interface in order from low to high priority. The intermediate power supply device corresponding to the third interface and the fourth interface shuts down the high-priority interface and opens the low-priority interface, and the corresponding standby power supply device provides power. At this time, the actual power supply power of the power supply device is 24w, which can meet the actual power consumption of the high-priority power receiving devices and does not need to be shut down again. For other interfaces, when the remaining power supply meets the maximum power consumption of the low-priority powered device, the interfaces of the power supply devices are opened in descending order of priority until the remaining power supply does not meet the maximum power consumption of the powered device. For example, at 7 o'clock, the actual power consumption of the first interface is 10w, the actual power consumption of the second interface is 10w, and the actual power consumption of the power supply device is 20w. At this time, the remaining power supply is 10w, which meets the maximum power consumption of the powered device of the third interface. Then the power supply device opens the interfaces from high to low, and the intermediate power supply device corresponding to the third interface closes the low-priority interface and opens the high-priority interface. The powered device of the third interface is powered by the main interface. At this time, the remaining power consumption is 0w, which does not meet the power consumption of the powered device of the fourth interface. The powered device of the fourth interface is powered by the backup power supply device, which can maximize the use of the power supply power of the power supply device, reasonably plan the power supply sequence of the power supply device, and provide a backup power supply device for the powered device when the power of the power supply device is insufficient and the powered device is about to be powered off, thereby ensuring the safety of the powered device and the stability of the power supply device, and having a good power supply coordination effect;
