Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are some, not all embodiments of the solution of the invention. All other embodiments obtained by a person skilled in the art without any creative effort based on the embodiments described in the present document belong to the protection scope of the technical solution of the present invention.
In the prior art, an NVR device supporting POE power supply generally supports power management of a single network interface, only limits an upper limit of power supply power of each network interface according to a protocol specification of POE, and does not limit total power supply power of all network interfaces. However, the total power of the NVR device is usually a fixed value, so that when the network terminal device connected to the NVR device through the network interface is excessive, that is, the POE power load of the NVR device is excessive, it is very easy to cause the power supply shortage of other functional modules of the NVR device to cause an abnormality, thereby causing the device life of the other functional modules to be reduced or damaged. In another possible case, the partial NVR device sets the total power supply of the network interface to a fixed value, which may result in a low utilization rate of the power allocated to the network interface when the fixed value is large and the network terminal device connected to the NVR device through the network interface is small; when the fixed value is small, the power allocated to each network terminal device may be too small, resulting in poor user experience.
In view of this, embodiments of the present invention provide a power management method, which is applicable to a power management device, and dynamically adjust a total power supply allocated to a network interface according to the number of data storage terminals connected to the power management device, so as to well avoid that the power supply allocated to the network interface is too large or too small, and improve the power utilization.
The technical scheme provided by the embodiment of the invention is described in the following with the accompanying drawings of the specification.
Fig. 1 is a scene diagram corresponding to a power management method according to an embodiment of the present invention. The NVR device is further provided with a plurality of Serial ATA (SATA) interfaces and a plurality of POE ethernet ports. Each POE Ethernet port on the NVR equipment is connected with an IPC, each POE Ethernet port supplies power to each IPC when performing data transmission with the IPC, and each SATA interface is connected with a hard disk, so that the NVR equipment can store data into the corresponding hard disk through the SATA interface. The SATA interface on the NVR equipment can also be other interface equipment which can be used for data transmission between the mainboard and the storage equipment; the hard disk may also be other available storage media, including but not limited to a magnetic disk memory, a flash memory, an optical memory, and the like, and the embodiments of the present invention do not limit this.
In the operation process of the NVR device shown in fig. 1, each POE ethernet port receives IPC video records through ethernet, and then the NVR device stores the received video records in a corresponding hard disk through a SATA interface. In this operating state, the overall power consumption (hereinafter referred to as power consumption) of the NVR device is divided as shown in fig. 2, and specifically may be divided into hard disk power consumption, board power consumption, and POE power supply power consumption. Wherein the hard disk consumption is the power loss when NVR equipment is external hard disk power supply, and POE power supply consumption is the power loss when NVR equipment passes through POE ethernet port and supplies power for the IPC of butt joint, and the veneer consumption is the produced consumption of main control unit and other components and parts normal operating in the NVR equipment.
When the NVR device is powered by the external adapter, the overall power consumption of the NVR device is provided by the adapter. When the NVR device operates normally, the power consumption of the board generally needs to be maintained within a certain range, otherwise, the NVR device may have a function abnormality. In addition, the power required by the NVR device to power a hard disk is usually a nominal value, and the power consumption of the hard disk can be usually determined by the number of hard disks connected to the NVR device. Therefore, the NVR device can dynamically adjust the total power provided to the POE ethernet ports according to the number of the connected hard disks, thereby preventing the occurrence of an abnormality that the POE power load of the NVR device is too large, which causes a situation that the power supply of the single board or the hard disk is insufficient, and also avoiding the problem of low power utilization rate of the NVR device.
It should be noted that the above-mentioned scenarios are merely presented to facilitate an understanding of the spirit and principles of the present invention, and the present examples are not intended to be limiting in any way. Rather, embodiments of the present invention may be applied in any scenario where applicable.
Referring to fig. 3, a flowchart corresponding to a power management method according to an embodiment of the present invention is shown, where the method is applicable to the power management apparatus shown in fig. 4, the power management apparatus includes a main controller, and the main controller is provided with a first interface module and a second interface module. The first interface module is used for connecting one or more data storage ends, wherein the first interface module can be directly connected with the one or more data storage ends or can be connected with the one or more data storage ends through one or more memory interfaces; the second interface module is used for connecting one or more data providing terminals through a plurality of network interfaces. Optionally, the power management apparatus may also include a POE controller, where the POE controller is connected to the main controller and each network interface. The power management method in the embodiment of the invention specifically comprises the following steps:
step 301: the main controller determines the number of data storage ends connected with the first interface.
As shown in fig. 4, the first interface module in the figure is used to connect with a plurality of data storage terminals (e.g. hard disk, flash memory, magnetic disk, etc.), and optionally, the first interface module may be directly connected with n data storage terminals, or may be connected with a plurality of data storage terminals through n memory interfaces, where each memory interface is used to connect with one data storage terminal. When N data storage ends are connected with the first interface module, the main controller can identify the number of the connected data storage ends through the first interface module, wherein N and N are positive integers.
Step 302: and the main controller adjusts the running power of the second interface module according to the number of the data storage ends. Wherein the operating power of the second interface module is related to the total operating power of the plurality of network interfaces.
After the main controller identifies the number of the data storage terminals, the operating power of the second interface module may be adjusted according to the number of the data storage terminals, wherein the operating power of the second interface module is also the total operating power allocated to all network interfaces by the main controller.
One possible source of power consumption in the power management apparatus shown in fig. 4 includes power consumed by the second interface module connecting to the data storage terminal and power consumed by the network interface connecting to the data providing terminal, wherein the power consumed by the first interface module connecting to each data storage terminal is a fixed value. When the total power in the power management device is a fixed value, the main controller can determine the numerical value of the operating power distributed to the first interface module through the number of the connected data storage ends, and then adjust the total operating power of the plurality of network interfaces according to the numerical value of the operating power.
For example, when the number of the data storage terminals is N, the main controller may adjust the operating power of the network interface to a-N × B, where a is the total power of the power management device and B is the power required by each data storage terminal of the N data storage terminals.
Another possible source of power consumption in the power management apparatus includes power consumed by the first interface module connecting to the data storage terminal, power consumed by the network interface connecting to the data providing terminal, and power consumed by other modules in the power management apparatus except the first interface module and the second interface module. In this case, when the number of the data storage terminals is N, the main controller may adjust the operating power of the second interface module to a-N × B-C, where a is a total power of the power management device, B is a power required by each data storage terminal of the N data storage terminals, and C is an operating power of other modules of the power management device, where the other modules are modules of the power management device except the second interface module and the second interface module.
The above step 302 illustrates the case where the POE controller is not included in the power management device. When the POE controller is included in the power management apparatus shown in fig. 4, the method further includes: the main controller sends a control command to the POE controller, wherein the control command comprises the numerical value of the operating power and can be used for indicating the POE controller to adjust the operating power of the plurality of network interfaces according to the operating power.
In the step 302, the main controller has adjusted the total operating power of the plurality of network interfaces according to the number of the data storage ends, and after that, after receiving the control command sent by the main controller, the POE controller may adjust the operating power of each network interface according to the value of the operating power. For example, the second interface module includes P network interfaces, where the P network interfaces are connected to P data providing terminals, and each network interface corresponds to one data providing terminal. After the POE controller receives the control command sent by the main controller, a possible situation is that the POE controller distributes the operating power to P data providing terminals on average, and the power received by each data providing terminal is equal. It is also possible that the P network interfaces have a priority order, wherein the priority order may be an order set by a user, a default order arranged according to the numbers of the network interfaces, or an order arranged according to the importance levels of the data providers connected to the network interfaces. For example, assume that network interface 1 has the highest priority, followed by network interface 2, then network interface 3, and other network interfaces. When the POE controller allocates the operating power to the P data providing terminals, according to the preset sequence of the priority, first allocating sufficient operating power to the network interface 1, then allocating the operating power to the network interface 2, and sequentially allocating the operating power to the P data providing terminals by the POE controller in the same manner. And when the total operating power distributed to the network interface by the main controller cannot meet the power required by all the data providing ends, the data providing ends with higher priority are preferentially met.
A power management method in an embodiment of the invention is further described with reference to the apparatus shown in fig. 5. As shown in fig. 5, when the power management method in the embodiment of the present invention is applied to the scenario shown in fig. 1, the corresponding first interface module in the power management apparatus may be an SATA interface module, and the SATA interface module expands a plurality of SATA interfaces (corresponding to a plurality of memory interfaces in the power management apparatus) through the SATA extension module, where the SATA extension module is composed of various SATA extension chips. In addition, each SATA interface of the plurality of SATA interfaces may be connected to a hard disk (data storage side) for storing data received from the host controller. The second interface module in the power management device may be an ethernet interface module, the ethernet interface module is connected to the uplink interface of the network switch, and a plurality of network interfaces are extended through the downlink interface of the network switch, and the plurality of network interfaces may be connected to a plurality of IPC devices (data receiving terminals) and receive data collected by the plurality of IPC devices. In addition, the main controller is connected with and controls the POE controller through an Inter-Integrated Circuit (IIC) bus. The POE controller is connected with each network interface respectively to control the operating power of each network interface, specifically include: the POE controller can control whether to supply power to the IPC devices connected to each network interface, or control the power supply of each IPC device. For example, the POE controller can control to allocate operating power only to the network interface 1 and the network interface 2 (equivalent to supplying power only to the IPC devices connected to the network interface 1 and the network interface 2), and not allocate operating power to other network interfaces (equivalent to not supplying power to the IPC devices connected to other network devices); alternatively, the POE controller may control the operation power allocated to the network interface 1 to be a, the operation power allocated to the network interface 2 to be b (which is equivalent to the power supply power of the IPC device connected to the network interface 1 to be a, and the power supply power of the IPC device connected to the network interface 2 to be b), and so on.
When the external power source supplies power to the power management device shown in fig. 5, the total power of the power management device is a constant value, which is denoted as a. The main controller in the power management device needs to distribute the total power to each module in the power management device so that the power management device can stably and safely operate. One possible way is that the host controller recognizes, through the SATA extension module, that the number of hard disks actually accessed to the SATA interface is N, and since the power consumed by each hard disk is generally a fixed value (denoted as B), the host controller may calculate, according to the number of hard disks, the operating power allocated to the SATA interface to be N × B. If the power consumed by the other modules in the power management apparatus except the SATA interface and the network interface during operation is a fixed value (denoted as C), the total operating power that the main controller needs to allocate to the network interface is a-N × B-C, which is equivalent to the total power supply power of the main controller to all the IPC devices being a-N × B-C. For example, when the SATA interface in the power management apparatus accesses a hard disk and the network interface accesses 3 IPC devices, the total power supply provided by the main controller for the 3 IPC devices is a-B-C. In addition, the POE controller may control the power provided to each IPC device to be (A-B-C)/3, or the POE controller may control the power provided to the first IPC device to be (A-B-C)/2, the power provided to the second IPC device to be (A-B-C)/2, and no power provided to the third IPC device. By using the power management method provided by the embodiment of the invention, the power provided for the IPC equipment is adjusted by identifying the number of the accessed hard disks, the total power in the power management device is fully utilized on the premise of ensuring the normal operation of the hard disks and other modules, and the utilization rate of the power is improved.
