1. Field of the Invention
The present invention relates to a powerline apparatus, and more especially, to the apparatus for providing power and network signal from powerline network by integrating the technology of Powerline Communication (PLC) and Power Over Ethernet (PoE).
2. Background of the Related Art
The technology of Powerline Communication (PLC) is a kind of the communication technology in which the data and the voice signal are transmitted by the powerline. The value of using powerline to transmit data is more and more important because the powerline has the characteristics of wide distribution areas and easily connection. Users who use the powerline networking technology can get the network signal through the powerline network by electrically connecting a powerline networking apparatus with the socket.
As shown in
The network apparatus can process the data transmission through the powerline network by using the foregoing powerline networking apparatus, however, the network apparatus, such as WebCam also needs another power cord to electrically connected to the socket, in order to obtain the operation power. Therefore, when the WebCam is increasingly needful, the sockets are not enough to supply for the power cords of the WebCams, and so as to have the disadvantage of not facile.
A Power Over Ethernet (PoE) technology is presently applied to transmit the direct current by the network cable, hence, the preexist network cable not only transmits the data, but also plays the role of power cord to transmit the power to the network apparatus connected with the network cable. Therefore, how to apply the PoE technology to the powerline networking apparatus is a technologic characteristic of the present invention.
In order to solve the forgoing problems, one object of this invention is to provide an apparatus for providing power and network signal from a powerline network, wherein the network power is transmitted together with the network signal to a network apparatus by a PoE module.
One object of this invention is to provide an apparatus for providing power and the network communication simultaneously by only the single power cord or plug electrically connected to the powerline network, and comparing with the conventional design in that the additional power components and sockets are required by the network apparatus, the present invention has the advantages of use easily.
One object of this invention is to provide an apparatus for providing power and network signal from a powerline network, which is integrated and configured within a shell, to facilitate the carry to have the advantage of high practicability.
Accordingly, one embodiment of the present invention provides an apparatus for providing power and network signal from a powerline network, which includes: a power component configured to electrically connect to a powerline network; a power unit electrically connected to the power component; a connecting port configured to electrically connect to a network apparatus; a PoE module electrically connected to the power unit and the connecting port, to get power from the power unit into a network power; and a network communication module electrically connected to the power component and the power unit, to access a network signal from the power component and transmit the network signal to the connecting port.
As shown in
The network communication module 34 includes a powerline-signal coupling unit 341, a signal processing unit 342 and an Ethernet access unit 343, wherein the powerline-signal coupling unit 341 is electrically connected to the power component 32, and the signal processing unit 342 is electrically connected to the powerline-signal coupling unit 341 and the Ethernet access unit 343, in order to make the signal processing unit 342 access the network signal from the alternating voltage of the power component 32 by means of the powerline-signal coupling unit 341, transform the network signal into a readable network signal for the network apparatus and then transmit the network signal to the PoE module 36 by means of the Ethernet access unit 343. The signal processing unit 342 is also used to transform an apparatus signal which comes from the network apparatus and is received by the Ethernet access unit 343 into the network signal and then transmit the network signal to the alternating voltage by the means of the powerline-signal coupling unit 341.
Continuously, the PoE module 36 includes a PoE unit 361 electrically connected to the power unit 38, and a PoE transformer 362 electrically connected to the PoE unit 361, the Ethernet access unit 343 and the connecting port 40. The PoE unit 361 is used to obtain the power from the power unit 38 and provide the power to the PoE transformer 362. At the same time, the PoE transformer 362 also receives the network signal from the Ethernet access unit 343 and then integrates the network signal with the network power. The integrated network signal is then transmitted to the network apparatus.
In one embodiment, the foregoing network communication module 34, PoE module 36, power unit 38 and connecting port 40 are integrated and configured within a shell (not shown in
On the other hand, in the present embodiment, the network signal and the network power do not need to be combined by the PoE transformer, because the RJ45 port has two spare pairs, which can be directly used to transmit the network power, simultaneously, the data receiving pair and the data transmitting pair are used to transmit the network signal.
Besides, in the present invention, the PoE transformer can be omitted from the PoE module 36 and the PoE unit 361 is directly and electrically connected to the power unit 38 and the connecting port 40. As shown in
To sum up, in the apparatus for providing power and network signal from a powerline network, one end of the electrical component is inserted into the socket to electrically connect to the powerline network to obtain the power and the network signal. The PoE module is used to provide the operation power to the network apparatus. Compared with the conventional design, in that the additional power components and sockets are required by the network apparatus which is connected with the powerline network, the operation of the network apparatus and the network communication in the present invention are achieved simultaneously by only the single power component electrically connected to the powerline network. Therefore, the present invention not only has the advantages of use easily, but also can decrease the cost of the additional power component and the socket. On the other hand, because the foregoing network communication module, the PoE module, power unit and connecting port are integrated and configured within a shell, the carry of the apparatus for providing power and network signal from a powerline network is quite convenient to have the advantage of high practicability and user friendly.
Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that other modifications and variation can be made without departing the spirit and scope of the invention as hereafter claimed.
