Term explanation:
Power over Ethernet (PoE): it is technology that transmits electric power and network data to devices through network cables in Ethernet. It was initially used for allowing small network devices such as IP phones, WLAN access points and webcams to directly obtain power from Ethernet.
PoE specification (IEEE 802.3): it is a set of standards of the Institute of Electrical and Electronics Engineers, which defines the media access control (MAC) of a physical layer and a data link layer of wired Ethernet, and generally involves local area network (LAN) technology with some wide area network (WAN) applications, which allows physical connection to be established between nodes and/or infrastructure equipment (hubs, switches, routers) through various types of copper cables or optical cables. Available power consumption obtained in the standards of IEEE 802.3 is as follows:
Power Sourcing Equipment (PSE): it provides power in a PoE system.
Powered Device (PD): it uses power in a PoE system.
Link Layer Discovery Protocol (LLDP): it is a data link layer protocol. A network device can inform other devices of its own status by sending a Link Layer Discovery Protocol Data Unit (LLDPDU) in a local network. LLDP is a protocol that enables devices in a network to discover each other, inform each other of their own status and exchange information.
As shown in
It should be understood that the number of devices and modules in
The power sourcing equipment 101 comprises an Ethernet switch, a router, a hub or other network switching devices supporting the PoE function, and a power adapter.
The powered device 102 comprises an electronic device such as a tablet computer, a notebook computer or an all-in-one computer that supports the PoE function.
According to some embodiments, the electronic device supporting the PoE function comprises an electronic device that has no battery.
A medium used by the communication link 103 to provide a network communication link between the power sourcing equipment 101 and the powered device 102 may be of various connection types, such as optical fiber cables and wireless communication links.
According to some embodiments, the powered device 102 sends an application for power allocation to the power sourcing equipment 101 via the communication link 103 through the LLDP protocol, and acquires power information allocated to the powered device 102 returned from the power sourcing equipment 101.
Generally, the power allocated to the powered device 102 is allocated by the power sourcing equipment 101 according to a power consumption limit in the PoE specification corresponding to the parameters of the power sourcing equipment.
For example, if the power sourcing equipment 101 supports the PoE (IEEE802.3af) standard, the power that the power sourcing equipment 101 can allocate is 12.95 W.
The power supply mode monitoring module 104 sets a power supply mode determination signal, and determines a power supply mode of the power sourcing equipment 101 according to a level of the determination signal.
According to some embodiments, the power supply mode determination signals include an AC IO signal and a PoE IO signal, wherein
when both the AC IO signal and the PoE IO signal are at a high level, power is supplied by the power adapter;
when the AC IO signal is at a high level and the PoE IO signal is at a low level, power is supplied by the power adapter; and
when the AC IO signal is at a low level and the PoE IO signal is at a high level, power is supplied in the PoE mode.
Generally, the power supply mode determination signals AC IO signal and PoE IO signal will not be at a low level at the same time.
The PoE power consumption estimation module 105 is used for acquiring a power consumption limit of the powered device 102 in the PoE mode and calculating first available power consumption, and acquiring an adjustment target of a PoE power-saving strategy through the PoE power-saving strategy module 106 and estimating power consumption data and second available power consumption of device functions in an adjusted PoE power-saving strategy.
According to some embodiments, the PoE power consumption estimation module 105 acquires currently used power consumption through a plurality of powered devices including the powered device 102, and calculates the first available power consumption in combination with the current power consumption limit of the PoE specification.
Further, the PoE power consumption estimation module 105 estimates power consumption data and remaining the second available power consumption of the device functions of the powered device 102 after performance adjustment (such as adjustment of LCD backlight brightness) and/or on or off of functions (such as on or off of the Bluetooth function) according to the first available power consumption and the adjustment target set by a user sent by the PoE power-saving strategy module 106.
The PoE power-saving strategy configuration module 106 is used for displaying the power consumption data of the device functions of the powered device 102 on the interactive interface 107 according to the first available power consumption and the second available power consumption. The user can operate through the interactive interface 107 and configure a device function adjustment target of the powered device. The PoE power-saving strategy configuration module 106 receives an instruction from the user through the interactive interface 107 and sends the device function adjustment target to the PoE power consumption estimation module 105.
According to some embodiments, the PoE power consumption estimation module 105 acquires the performance parameters of the powered device 102, and estimates the power consumption data of the device functions of the powered device 102 in the PoE power-saving strategy configuration module 106 according to empirical data.
For example, the performance parameters of the powered device 102 include liquid crystal display (LCD) backlight brightness, network connection condition, USB interface use condition and speaker volume, etc. If the LCD backlight brightness is 30%, LCD backlight power consumption is estimated to be 0.90 W according to empirical data.
The user can turn off or on the device functions of the powered device in the interactive interface 107 according to his/her own using habits. The PoE power-saving strategy configuration module 106 responds to the operation of the user and feeds data back to the PoE power consumption estimation module 105 and the powered device 102 to prevent the power consumption of the system from exceeding a PoE limit due to the activation of too many functions.
According to some embodiments, the functions of the powered devices controlled in the PoE power-saving strategy configuration module 106 cannot be turned on or off by other systems or modules.
As shown in
According to some embodiments, the power supply mode of the power sourcing equipment is determined first through a power supply mode monitoring module, and if power is supplied in the PoE mode, the power consumption limit of the powered device is acquired through the LLDP protocol according to the PoE specification supported by the power sourcing equipment.
In S203, receiving an adjustment operation instruction from a user, and setting an adjustment target according to the adjustment operation instruction.
According to some embodiments, the user acquires available power consumption and real-time power consumption data of the powered device through a PoE power-saving strategy configuration module, and operates according to his/her own needs to set a device function adjustment target of the powered device.
Further, the PoE power-saving strategy configuration module transmits the device function adjustment target to a PoE power consumption estimation module according to an operation instruction of the user.
In S205, estimating available power consumption and real-time power consumption data of the powered device according to the power consumption limit of the powered device and the adjustment target.
According to some embodiments, the PoE power consumption estimation module acquires first available power consumption by calculating a difference between the power that can be provided by the power sourcing equipment and the power obtained by the powered device under the PoE specification.
Further, second available power consumption is estimated according to the first available power consumption and the setting of the device functions of the powered device in the PoE power-saving strategy module.
Generally, the PoE power-saving strategy module and the PoE power consumption estimation module are enabled when the power supply mode is the PoE mode, and disabled when the power supply mode is not PoE mode (such as power adapter).
The device functions of the powered device in the PoE power-saving strategy module include, but are not limited to, adjustment of LCD backlight brightness, enabling/disabling of a mobile network, enabling/disabling of Wi-Fi, enabling/disabling of Bluetooth, enabling/disabling of USB, adjustment of speaker volume, enabling/disabling of an external display and enabling of a power saving mode of a processor.
Generally, the power saving mode of the processor is enabled by default when specific power consumption cannot be allocated through the LLDP protocol due to large power consumption of the powered device.
Theoretically, only when the power sourcing equipment only supports the PoE (IEEE802.3af) standard and the maximum power consumption that can be allocated to the powered device is 12.95 W can the power saving mode of the processor be enabled.
According to the device function parameters of the powered device and empirical data, the PoE power consumption estimation module estimates the real-time power consumption data of the device functions of the powered device.
In S207, adjusting device functions of the powered device based on the available power consumption and the real-time power consumption data, and displaying adjusted available power consumption and adjusted real-time power consumption data.
According to some embodiments, the device functions of the powered device can be managed and adjusted by using a default power consumption configuration, which enables the functions of the powered device to the maximum extent according to the power consumption limit of the powered device.
Generally speaking, the product specifications and power consumption of different powered devices are different, and the default power consumption configurations adopted are also different due to different levels of allocatable power consumption under different PoE specifications and different user needs.
For example, for Elo i-series 4.0 and a 10-inch device, the default configuration under the PoE+(IEEE 802.3 at) standard is as follows:
LCD backlight brightness: 80%;
Thunderbolt USB: off;
USB 3.0: off;
USB 2.0: off;
Bluetooth: on;
Wi-Fi: off;
Speaker volume: 50%;
External display: off;
Power saving mode of processor: off.
For another example, for Elo i-series 4.0 and a 22-inch device, the default configuration under the PoE+(IEEE 802.3 at) standard is as follows:
LCD backlight brightness: 70%;
Thunderbolt USB: off;
USB 3.0: off;
USB 2.0: off;
Bluetooth: on;
Wi-Fi: off;
Speaker volume: 0;
External display: off;
Power saving mode of processor: off.
According to some embodiments, the user can adjust the device functions in the default power consumption configuration, including turning off or on some functions, according to his/her own using habits, the available power consumption under the PoE specification supported by the power sourcing equipment and the real-time power consumption data of the device functions in the PoE power-saving strategy module.
Further, after the device function adjustment of the powered device is completed, the adjusted available power and the real-time power consumption data of the device functions are displayed to the user through the PoE power-saving strategy module.
As shown in
Generally speaking, the PoE power-saving strategy can be adjusted according to the power consumption data in the device functions of the powered device from high to low, or according to the actual needs of the user.
As shown in the embodiment of
After the LCD backlight brightness adjustment is completed, whether to enable or disable a Thunderbolt USB channel, a USB3.0 channel and a USB2.0 channel are determined in turn according to the PoE power-saving strategy, and functional configuration of a USB interface is performed.
After the USB interface configuration, network connection configuration is performed, including enabling or disabling a mobile network and Wi-Fi.
If the mobile network is disabled, the powered device is switched to an airplane mode.
Further, whether Bluetooth is enabled or not is determined.
Further, whether to switch the processor to the power saving mode is determined according to the PoE specification supported by the power sourcing equipment.
Finally, speaker volume adjustment is performed, so that the PoE power-saving strategy is enabled.
As shown in
Under the PoE+(IEEE 802.3at) standard, the power consumption provided by the power sourcing equipment is 25.5 W, of which 13.00 W has been used and the available power consumption is 12.50 W.
As shown in
LCD backlight brightness: 30%, power consumption: 0.90 W;
Speaker volume: 25%, power consumption: 0.25 W;
Mobile network: off, power consumption: 3.25 W;
Wi-Fi: off, power consumption: 2.80 W;
Bluetooth: off, 1.00 W;
Thunderbolt USB: off, power consumption: 5.60 W;
USB 3.0: off, power consumption: 4.50 W;
USB 2.0: off, power consumption: 2.00 W;
External display: off, power consumption: 1.00 W;
Power saving mode of processor: off, power consumption: 1.20 W.
The user can adjust corresponding functions, such as turning them off or on. The PoE power-saving strategy module responds to the operation of the user and sends instructions, and makes the powered device adjust its own functions. That is,
the PoE power-saving strategy provides a power consumption protection mechanism for the powered device, which prevents instability caused by the power consumption exceeding the power consumption limit in the PoE specification due to the activation of too many functions of the powered device.
As shown in
The PoE power-saving strategy configuration module transmits the new brightness data obtained after modification and original brightness data to the PoE power consumption estimation module.
The PoE power consumption estimation module estimates new brightness power consumption according to the new brightness data, and estimates original brightness power consumption according to the original brightness data.
According to the new brightness power consumption, the original brightness power consumption and the current available power consumption, new available power consumption is calculated, that is, new available power consumption= current available power consumption + original brightness power consumption-new brightness power consumption.
If the new available power consumption is greater than 0, information is sent to the powered device, the LCD backlight of the powered device is set to the new brightness, and the current power consumption data of the powered device are updated.
If the new available power consumption is less than or equal to 0, the user is prompted through the interactive submodule in the PoE power-saving strategy configuration module that the LCD backlight brightness cannot be modified.
For example, according to the information in the interactive submodule interface of the PoE power-saving strategy as shown in
Assuming that the Thunderbolt USB, USB3.0 and USB2.0 are all enabled and in a working state currently and the respective estimated power consumption is 5.60 W, 4.50 W and 2.00 W,
the current LCD backlight brightness is 30% and the estimated power consumption is 0.90 W,
the current available power consumption is calculated, that is, based on the available power consumption of the current power sourcing equipment and the power consumption of the currently enabled functions, the current available power consumption=12.50 W−5.60 W−4.50 W−2.00 W=0.40 W.
If the user tries to adjust the LCD backlight brightness to 70% and the estimated power consumption is 3.20 W, then the new available power consumption=0.40 W+0.90 W−3.20 W=−1.90 W<0.
It can be seen that the new available power consumption is less than 0, and the interactive submodule interface of the PoE power-saving strategy displays the prompt message of “exceed PoE power consumption limit”, so the user cannot adjust the LCD backlight brightness to 70%, but can make the adjustment again after disabling some other functions.
As shown in
The PoE power-saving strategy configuration module sends data to the PoE power consumption estimation module, and the PoE power consumption estimation module estimates the power consumption of the Bluetooth function.
According to the power consumption of the Bluetooth function and the current available power consumption, the new available power consumption is calculated, that is, the new available power consumption=current available power consumption−Bluetooth power consumption.
If the new available power consumption is greater than 0, information is sent to the powered device, the Bluetooth function of the powered device is enabled, and the existing power consumption data of the powered device are updated.
If the new available power consumption is less than or equal to 0, the user is prompted through the interactive submodule in the PoE power-saving strategy configuration module that adjustment or modification cannot be made.
For example, according to the information in the interactive submodule interface of the PoE power-saving strategy as shown in
Assuming that the Thunderbolt USB, USB3.0 and USB2.0 are all enabled and in a working state currently and the respective estimated power consumption is 5.60 W, 4.50 W and 2.00 W,
the current LCD backlight brightness is 30% and the estimated power consumption is 0.90 W,
the current available power consumption is calculated, that is, based on the available power consumption of the current power sourcing equipment and the power consumption of the currently enabled functions, the calculated current available power consumption=12.50 W−5.60 W−4.50 W−2.00 W=0.40 W.
If the user tries to enable the Bluetooth function and the estimated power consumption is 1.00 W, then the calculated new available power consumption=0.40 W−1.00 W=−0.60 W<0.
It can be seen that the new available power consumption is less than and the interactive submodule interface of the PoE power-saving strategy displays the prompt message of “exceed PoE power consumption limit”, so the user cannot enable the Bluetooth function, but can try it again after disabling some other functions.
