Network power device

A network device, particularly related to a network power device.

With the popularization of the Internet, the decoration will also put forward corresponding requirements for the network infrastructure. However, for the old buildings, the wiring of the physical network is difficult due to the wiring decoration. In particular, a network camera or a network device that needs to be powered can be operated because the network cabling is not easy and the device itself requires external power. Therefore, some manufacturers propose to use Ethernet to transmit data packets and operate power simultaneously.

The power over Ethernet (PoE) includes a Power Sourcing Equipment (PSE) and a Powered Device (PD). PoE does not need to change the cable architecture of the Ethernet to operate, so the PoE system not only saves cost, but also has the ability to remotely power on and off. The PoE further includes two protocols, IEEE 802.3AF (Institute of Electrical and Electronics Engineers, IEEE for short) and IEEE 802.3AT. The two protocols separately specify different transmission voltages and powers. In the AF protocol, the PSE provides 44~57V voltage, about 350mA DC power supply, and each raft must provide at least 15.4W of power. After 100m CAT-3 cable, the PD can receive at least wattage. Have 12.95W. In the AT protocol, the PSE terminal provides 50~57V voltage, about 600mA DC power supply, and each 埠 must provide at least 30W power. After 100m CAT-5 cable, the PD terminal can receive at least wattage. Have 25.5W.

Regardless of the protocol, the architecture of PSE and PD is a topological structure. In other words, the PSE and PD in the same network form a multi-point connection. The advantage of this architecture is that the setup is flexible. However, the disadvantage is that the management of the PD is not easy, so that too many PDs will seriously affect the quality of the power supply.

The present invention provides a network power device, which provides a serial connection structure between a power supply end and a multi-power receiving end, so that the power supply end can accurately grasp the number of connected power receiving ends.

The network power device of the present invention comprises a first network transmission end, a second network transmission end and a power module, and the power module is respectively connected to the first network transmission end and the second network transmission end, and the power module passes through the A network transmission end receives an input power, the first network transmission end transmits a data packet of an Ethernet network, and the second network transmission end is connected to a network device, and the power module generates a current output value, The second network transmission end transmits the data packet and an output power to the network device.

The novel network power device proposes a daisy chain connection structure, so that the power supply end can confirm the number of power receiving ends, thereby controlling whether the power receiving end is enabled.

Please refer to Figure 1, which is a schematic diagram of the new system architecture. The network device power system of the present invention includes a power supply end 100 and a power receiving end 200. The power receiving end 200 is a new type of network power device. For convenience of explanation in the present specification, the power supply terminal 100 and the plurality of power receiving terminals 200 are connected in a daisy chain manner. However, the actual power supply terminal 100 and the power receiving terminal 200 are not connected one by one. The network power device may be a network camera, a network hub or a network telephone.

The power supply terminal 100 has a third network transmission end 111, a power conversion module 112, and a fourth network transmission end 113. The power conversion module 112 is connected to the third network transmission end 111 and the fourth network transmission end 113.

The power receiving end 200 (which is a new type of network power device) includes a first network transmission end channel transmitting end 211, a power module 212, a dip switch 213 and a second network transmission end 214. the first The network transmission end 211 is connected to the fourth network transmission end 113. The power module 212 is connected to the first network transmission end 211, the dip switch 213 and the second network transmission end 214. The first network transmission end 211 is networked to the third network transmission end 111. The power module 212 receives input power from the power supply terminal 100. The power module 212 further determines whether to output output power to the connected other power receiving terminals 200 according to the connected other power receiving terminals 200. In addition to determining the output power by the power module 212, the user can also operate the dip switch 213 to determine whether to generate output power to the connected other power receiving terminal 200. The types of the first network transmission end 211, the second network transmission end 214, the third network transmission end 111 and the fourth network transmission end 113 are the physical network interfaces of the IEEE 802.3 series.

In the present specification, in order to clearly explain the operation of the multi-receiving end, in the second drawing, three power receiving ends 410, 420, and 430 are used as an operation. In this embodiment, the first power receiving end 410, the second power receiving end 420, and the third power receiving end 430 are described. In this embodiment, the components of the first power receiving end 410, the second power receiving end 420, and the third power receiving end 430 are distinguished, thereby further defining the first power receiving end 410, the second power receiving end 420, and the third power receiving end 430. The name of each component.

The first power receiving end 410 includes a first network transmission end 411, a first power module 412, a first dip switch 413 and a second network transmission end 414. The second power receiving end 420 includes a third network transmission end 421, a second power module 422, a second dip switch 423, and a fourth network transmission end 424. The third power receiving end 430 includes a fifth network transmission end 431, a third power module 432, a third dip switch 433, and a sixth network transmission end 434. The first power module 412 is connected to the first network transmission end 411, the second network transmission end 414 and the first dip switch 413. The second power module 422 is connected to the third network transmission end 421, the fourth network transmission end 424, and the second dip switch 423. The third power module 432 is connected to the fifth network transmission end 431, the third power module 432, the third dip switch 433, and the sixth network transmission end 434. The functions of the respective elements in the first power receiving end 410, the second power receiving end 420, and the third power receiving end 430 are the same as those described in the foregoing. It is assumed that the required loads of the first power receiving end 410, the second power receiving end 420 and the third power receiving end 430 are the same.

The power receiving end 300 is connected to the first power receiving end 410, the second power receiving end 420 is connected to the first ground receiving end, and the third power receiving end 430 is connected to the second power receiving end 420. It is assumed that the power supply terminal 300 can supply 20 W of load power, and each power receiving end uses 5 W. Therefore, under ideal conditions, the power supply terminal 300 can provide four operating powers that are normally used by the power receiving end.

The novel can be used as a basis for judging the output power through the connection detection method or the operation of the dip switch. For the connection detection, when the first power receiving end 410 is connected to the power supply terminal 300 for the first time, the first power module 412 tests the maximum output power that the power supply terminal 300 can provide. When the first power module 412 is connected to the power supply terminal 300 for the first time, the first power receiving terminal 410 performs a test for matching the power required by the power supply terminal 300 according to the required load, and is used to ensure that the power provided by the power supply terminal 300 can be The first power receiving end 410 is operated.

Then, the first power module 412 increases the load in a multiple manner for measuring the upper supply limit of the power supply terminal 300. As described above, the power supply terminal 300 can provide 20W of power. The first power receiving end 410 starts to increase the load from a multiple of 5 W, and successively tests whether the input power meets the power required by the load. When the input power obtained by the first power receiving end 410 is greater than the own load, the first power receiving end 410 transmits the additional power to the second power receiving end 420.

In addition, the user can operate the first dip switch 413 of the first power receiving end 410 for determining the number of other power receiving ends to which the first power receiving end 410 can be connected. In this embodiment, the first power receiving end 410 is connected to the second power receiving end 420 and the second power receiving end 420. Therefore, the user can adjust the order of the first dip switch 413 to "2". The first power module 412 calculates a corresponding output power according to the magnitude of the first finger switch 413, and tests whether the power generated by the power terminal 300 satisfies the output power. If the power provided by the power supply terminal 300 can satisfy the output power, the first power module 412 will output the output power to the second power receiving terminal 420. Similarly, the second power receiving end 420 is only connected to the third power receiving end 430. Therefore, the magnitude of the second dip switch 423 can be set to "1". When the second dip switch 423 is set to "0", the second power receiving end 420 will not generate output power to the third power receiving end 430.

In addition to providing operating power of other network devices, the network power device of the present invention can also determine whether to output power to the next connected network device according to the power provided by the power supply terminal 300.

Although the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the present invention, and it is intended that those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. The scope of the new patent protection shall be subject to the definition of the scope of the patent application attached to this specification.
