As mentioned before, there is a need for an improved ethernet solution. In existing ethernet networks, power transfer is unidirectional, i.e. only from a power sourcing equipment (Power Sourcing Equipment, PSE) to a Powered Device (PD). And the whole network usually only has one PSE to supply power to the PD, the redundancy of the whole system is insufficient. To prevent the PSE from downtime, a conventional solution is to provide an uninterruptible power supply (Uninterruptible Power Supply, UPS) between the mains and the PSE. However, UPS's are costly and unsuitable for small systems. Accordingly, it is desirable to have a less costly backup power solution that increases system redundancy in wired network communications.
Embodiments of the present disclosure provide an improved battery device for use in a wired communication network, the battery device allowing bi-directional transmission of power and data in the wired communication network, the battery device comprising: first and second interface means adapted to be coupled to a device in a wired communication network, and coupled to each other; and a battery management module coupled to the first interface device and the second interface device and configured to control operation of the battery device according to signals received from the first interface device and the second interface device. According to embodiments of the present disclosure, redundancy of a wired communication network may be effectively increased by providing a dual-interface battery device that allows bi-directional power transfer. The battery management module can operate the electric device to charge and discharge according to the state of the interface device, which is low in cost and suitable for small-sized systems.
Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Fig. 1 illustrates a schematic diagram of a battery device 100 for use in a wired communication network according to some exemplary embodiments of the present disclosure. As shown in fig. 1, the battery apparatus 100 may include connectors 180 and 182 adapted to be connected to wired data links such as ethernet cables, and examples of the connectors 180 and 182 may be RJ45 interfaces, for example, RJ45 interfaces may be used for data terminal equipment types of ethernet cards, router ethernet interfaces, and the like, and types of digital communication equipment for switches and the like. The battery apparatus 100 may be coupled to various devices in a wired network through connectors 180 and 182 to receive data and power from or transmit data and power to the devices in the network.
In some embodiments, battery apparatus 100 may be coupled to a power sourcing equipment (or powered device) through connector 180 and may be connected to a powered device (or powered device) through connector 182. Alternatively, in some embodiments, battery device 100 may be coupled to a power supply apparatus through both connectors 180 and 182. Additionally or alternatively, in some other embodiments, battery apparatus 100 may be coupled to a power sourcing or a powered device in the network through one of connectors 180 and 182, while the other connector is not used. Note that the number of types of connectors 180 and 182 are merely exemplary and are not intended to limit the scope of the present disclosure.
Connectors 180 and 182 are adapted to couple to data converter 170 and first interface device 120. The data converter 170 is adapted to convert electrical signals received from the network into data and transmit to the ethernet switch 160 or to convert data received from the ethernet switch 160 into electrical signals and transmit to devices in the network. In some embodiments, the data converter 170 may be a magnetic coupling element including a transformer.
As shown in fig. 1, the data transmission path is shown by dashed lines, and the network switch is configured to route or relay data messages between devices (not shown in fig. 1) to which connectors 180 and 182 are coupled. The data converter 172 and the data converter 170 are similar in function and will not be described in detail herein.
The first interface means 120 is adapted to be coupled to a device in a wired communication network via a connector 180 for providing power or receiving power, and the second interface means 122 is adapted to be coupled to a device in a wired communication network via a connector 182 for providing power or receiving power. The first interface means 120 is adapted to be coupled to the second interface means 122. The detailed circuit structure of the first interface device 120 and the second interface device 122 will be described below in conjunction with fig. 3.
The battery device 100 further comprises a battery management module 110, the battery management module 110 being coupled to the first interface device and the second interface device and being configured to control the operation of the battery device 100 in dependence of signals received from the first interface device and the second interface device. The operation of the battery device 100 may include a charging operation, a discharging operation, and a standby operation. The operation of the battery device 100 will be described in further detail with reference to fig. 3 to 5.
As can be seen from the power transmission path shown by the solid line in fig. 1, the battery device 100 allows bi-directional transmission of power and data in the wired communication network. Thereby increasing redundancy of the wired communication network in place of UPS. As can be seen from the structure of the battery device 100, it is low in cost and easy to install and carry, thereby ensuring convenience while increasing redundancy, and also reducing costs.
The battery device 100 further comprises an energy buffer module 140, the energy buffer module 140 being coupled between the battery management module 110 and said first interface device 120 and second interface device 122. The energy buffer module 140 is configured to temporarily store energy during operation of the battery device 100. Energy buffer module 140 is coupled to ethernet switch 160 for providing power to ethernet switch 160.
In some embodiments, an isolated power supply 150 is disposed between the network switch 160 and the energy buffering module 140. The isolated power supply 150 is configured to transmit a regulated DC voltage (e.g., 3.3V) to the ethernet switch 160 to further ensure proper operation of the ethernet switch 160. The energy buffer module and the isolation power supply can ensure the data transmission in the wired communication network, and the stability of the data transmission in the network is improved.
The energy buffer module 140 is also configured to act as a buffer when power is transferred between the battery management module 110 and the first and second interface devices 120 and 122 during operation of the battery device 100. In some embodiments, the energy buffer module 140 may include one or more capacitors, or supercapacitors, or electrochemical cells.
Having described the basic structure of the battery device according to fig. 1, for convenience in describing various operations of the battery device 100, the interface device is first described with reference to fig. 2. Fig. 2 illustrates a circuit configuration diagram of an interface device according to some exemplary embodiments of the present disclosure. The interface device 200 may be the first interface device and the second interface device described above.
The interface device 200 can be connected to a wired telecommunication network, such as an ethernet based network. In some embodiments, the interface apparatus 200 is adapted to be coupled to a network device in a network, such as a computer, a mobile communication device, a sensor, a camera, a multimedia device, an industrial control device, or the like.
The interface device 200 interface may include communication components 202 and 204, the communication components 202 and 204 being configured to couple the interface device 200 to a wired communication network. In some embodiments, the communication components 202 and 204 each include a pair of pins adapted to couple to a wired communication network, for example, for coupling to an ethernet cable. Although illustrated as a pair of pins, the communication components 202 and 204 may also include other pins not shown in fig. 2. The present disclosure is not limited herein.
The interface device 200 interface may also include a rectifier 210, the rectifier 210 being coupled to the communication component 202. In some embodiments, rectifier 210 may be in the form of a diode rectifier bridge that includes a plurality of diodes D1, D2, D3, and D4 arranged in a conventional manner. Alternatively, in some other embodiments, the rectifier 210 may also be composed of a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET).
The interface device 200 interface may also include a power bus 220, the power bus 220 being coupled to the rectifier 210. The power bus 220 is adapted to receive power from a wired communication network or to deliver power to a wired power network.
The interface device 200 further includes a first controller 240 and a second controller 250 coupled between the rectifier 210 and the power bus 220. The first controller 240 and the second controller 250 may be electronic controllers implemented by electronic circuits and/or processor-based control devices. Although the first controller 240 and the second controller 250 are illustrated as separate controllers, in some cases, the first controller 240 and the second controller 250 may be implemented by the same electronic circuit.
The interface apparatus 200 may also include a first switch 530, the first switch 530 coupled to the first controller 540 and configured to be controlled by the first controller 540 to selectively block current flow between the communication components 502 and 504 and the power bus 520. The interface device 200 further includes a second switch 532 and a third switch 534, respectively, coupled to the second controller 550 and configured to be controlled by the second controller 550 to selectively block current from flowing from the power bus 520 through the communication components 502 and 504. In some embodiments, the first, second, and third switches 530, 532, 534 may be electromechanical switches, relays, electrical switches, or transistor-based switches.
In some embodiments, the interface device 200 may include a first resistor R1 connected in parallel with the rectifier 510 that is capable of detecting the voltage across the communication components 202 and 204 when the interface device 200 is not powered to detect the presence of a powered device in the network. In some embodiments, the interface device 200 may include a second resistor R2 coupled to the second controller 550 for sensing current flowing through the power bus 520.
In one example, the first controller 240 is configured to control the power supply of the first interface device 120 by a device in the wired communication network and to send a first signal to the battery management module 110 indicating that the first interface device 120 is to be powered by the device in the wired communication network. For example, when the first interface device 120 is powered by a power supply in the network, the first controller 240 closes the first switch 230, at which point current may flow from the communication component to the power bus. At the same time, the first controller 240 sends a signal to the battery management module indicating that the off-site interface device is powered by the power supply apparatus. The battery management module may cause the battery 130 to be charged according to the state of the battery at this time.
In another example, the second controller 250 is configured to control the power supply of the battery apparatus 100 to devices in the wired communication network and to send a second signal to the battery management module 110, the second signal indicating that the first interface apparatus 120 is to power the devices in the wired communication network. For example, first the second switch 232 and the third switch 234 are opened. The second controller 250 detects that neither the first interface device 120 nor the second interface device 122 is coupled to the power supply equipment or that the power supply equipment is coupled to the power supply equipment but the power supply equipment is down. At this time, if the battery apparatus 100 needs to supply power to the devices in the network, the second controller 250 causes the second switch 232 and the third switch 234 to simultaneously transmit a signal indicating that the devices in the wired communication network are to be supplied with power to the battery management module 110, current may flow from the battery 130 to the interface apparatus to supply power to the devices in the network.
It is understood that the operation of the second interface device 122 is similar to that of the first interface device 120, and will not be described herein. It should be appreciated that the above circuit configuration is merely exemplary. Different operations of the battery may also be implemented using different circuit configurations, and the disclosure is not limited herein.
The operation of the battery device 100 is described below with reference to fig. 3 to 5. Fig. 3 illustrates a schematic diagram of one operational state of the battery device 100 used in a wired communication network according to some exemplary embodiments of the present disclosure.
As shown in fig. 3, the first interface device 120 is coupled to a power sourcing equipment 302 and the second interface device 122 is coupled to a powered device 304, the power sourcing equipment 202 being in an on state. At this time, as described above, the first controller 240 of the first interface device 122 detects the presence of a power supply device in the network, at which time it may cause the first switch 230 to close and send a signal to the battery management module 110 to be charged. The battery management module 110 may control the operation of the battery in response to receiving the signal.
In some embodiments, the battery management module 110, upon receiving the charging signal, may detect an energy level of the battery 130, and charge the battery 130 in response to the energy of the battery being less than a threshold energy (e.g., less than 80% of the charge). And as shown by the power path indicated by the solid line in fig. 3, the powered device 304 receives power from the power sourcing equipment 302 via the first interface arrangement 120 and the second interface arrangement 122.
Fig. 4 illustrates another schematic diagram of another operational state of a battery device used in a wired communication network according to some exemplary embodiments of the present disclosure. At this point, the battery is considered to be fully charged without receiving additional power.
In some embodiments, the battery management module 110, upon receiving the charging signal, may detect an energy level of the battery 130, and in response to the energy of the battery being greater than a threshold energy (e.g., greater than 80% of the charge), put the battery 130 on standby. And the powered device 304 receives power from the power sourcing equipment 302 via the first interface apparatus 120 and the second interface apparatus 122. It will be appreciated that the powered device 304 receives power from the power sourcing equipment 302 regardless of the energy of the battery. The only difference is that when the battery charge is greater than the threshold, the battery is bypassed without charging.
Fig. 5 illustrates another schematic diagram of yet another operational state of a battery device used in a wired communication network according to some exemplary embodiments of the present disclosure. As shown in fig. 5, the first interface device 120 is coupled to a power sourcing equipment 302 and the second interface device 122 is coupled to a powered device 304, the power sourcing equipment 302 being in an off state (represented by a dashed line). At this time, no power supply device supplies power in the wired communication network. The second controller of the second interface device 122 may close the second switch and the third switch and send a signal to the battery management module 110 indicating that the flashlight device 304 in the network is to be powered. The battery management module 110 causes the battery apparatus 100 to provide power to the powered 304 device via the second interface apparatus 122 in response to receiving the signal. Thus, the battery device according to the present disclosure can provide high redundancy for small systems and apparatuses. Meanwhile, the battery is simple in structure and easy to carry and install, and can supply power for various wired networks.
Fig. 6A-6B illustrate schematic diagrams of wired networks according to one exemplary embodiment of the present disclosure. As shown in fig. 6A and 6B, a wired network includes a battery device and other network equipment. In fig. 6A, the power supply apparatus 610 operates normally and supplies power to the power receiving apparatuses 620-1 and 620-2 in the network, and also charges the battery device 630. In fig. 6B, the power supply apparatus 610 fails, at which time the power receiving apparatuses 620-1 and 620-2 are powered by the battery device 630. Thus, a battery device according to the present disclosure may provide additional redundancy while having the advantage of low cost.
Fig. 7 shows a schematic diagram of a wired network according to another exemplary embodiment of the present disclosure. As shown in fig. 7, the wired network system includes a plurality of power receiving and supplying devices and a battery device. It can be seen that the battery arrangement 710 provides additional redundancy to the wired network and is easily deployed into the network. Furthermore, the network of fig. 7 forms a closed loop, which enables additional redundancy and security.
