Description

Ethernet communication equipment and its bridge

technical field

The utility model is an Ethernet communication device which obtains +5V DC voltage from a USB port of a computer device. The communication device does not need to be built-in or externally connected with an extra DC power transformer, and the computer can be directly used by the USB port of the computer device. The DC power supply of the equipment is used for the power supply required by the communication equipment for Ethernet signal modulation and transmission.

Background technique

With the generalization of personal computers and the rapid development of the network, it is not surprising that a family has more than two computer devices. Therefore, it is not surprising to build a computer in the family or office that can connect all the computer devices in the house, so that everyone can share and "Home networks" and "office networks" that control these devices also emerged.

At present, the main local area network access technologies of computer equipment in general homes and offices include Ethernet (Ethernet) interface, USB interface and wireless network (Wireless LAN) interface. Among them, Ethernet (Ethernet) and USB are currently the most mature and common area network access technologies. Almost all computer equipment is equipped with Ethernet (Ethernet) RJ45 connectors and USB connectors. It's just that the common problem of Ethernet is the trouble of wiring, while USB has the trouble of driver installation on computer equipment. As shown in Figure 1, what it depicts is a kind of current Ethernet access technology, and this technology is to utilize a kind of network modulator 6, such as ADSL modem or CableModem to connect with the external Internet 7 and then become with the outside world Communication information pipeline, if there are several computer devices in the room and want to contact the external Internet at the same time, they must first be connected with a hub (HUB) 5, as shown in Figure 1, the computer devices A, B, C, and D are configured in the same The equipment in the room is equipped with a network card (not shown, but it is represented by its Ethernet (Ethernet) transmission interface 10, 20, 30, 40 that each computer device is equipped with a network card) and connected with a network cable. The hub 5 is connected, and accordingly, each computer equipment A, B, C, D in the room can carry out data transmission with the external Internet 7, but as mentioned above, such a wiring method requires a large amount of network wiring in the room In addition to the original power line and telephone line in the room, an additional Ethernet (Ethernet) network line needs to be arranged, and a computer device needs a network line to connect to the hub 5, and the length of the network line needs to be measured in advance OK, otherwise there will be situations where the network cable is insufficient or too long.

For this reason, there is a telephone line network (HomePNA standard) access technology, which only needs to connect a telephone modulator to each computer device and ADSL or Cable Modem to convert the Ethernet (Ethernet) signal The HomePNA signal is used to transmit the signal to the telephone line, which can avoid the construction and layout of the Ethernet network line. Use the telephone line originally configured in the room to communicate information between the computer equipment and the external Modem. However, when new computer equipment is added to the indoor environment of this technology, it is necessary to add a telephone socket to connect with the indoor telephone line in order to use the existing The telephone line is connected with many other computers to form a local area network.

Since power lines are the most widely distributed and embedded in the room, and power sockets can be seen almost everywhere in ordinary homes or offices, so a power line network (HomePlug standard) access technology has been developed by taking advantage of this advantage. The network (Ethernet) signal is converted into a HomePlug signal and transmitted on the original power line in the building, so that the problems of excessive wiring and new telephone sockets can be avoided, and the home network and office network can be easily established.

At present, there are two types of Ethernet (Ethernet) bridges that use power lines for data transmission. One is an Ethernet (Ethernet) bridge (Bridge), which uses an RJ45 connector as an interface connected to a computer device (as shown in Figure 2A). The other is a USB bridge, which uses a USB connector as an interface for connecting with a computer device (as shown in FIG. 2B ). Among them, the Ethernet (Ethernet) bridges 200, 220 use 110V/220V AC power from the power line 210 to supply the DC power required by the bridge itself when transmitting signals, so the Ethernet (Ethernet) bridges 200, 220 need internal Only by building DC transformers 203 and 223 or adding an additional DC power transformer can the DC voltage required for its work be provided. However, the USB bridge 250 used in FIG. 2B can directly obtain +5V DC power from the USB port on the computer device F connected to it to supply the DC power required by itself when transmitting signals. Since the computer device F uses DC voltage when it works, the USB bridge 250 can obtain the power required for signal transmission without a built-in transformer.

Although the Ethernet (Ethernet) bridge requires a built-in or external transformer, the cost of the entire device is about 2 to 4 dollars more expensive than the USB bridge, and it becomes too bulky due to the built-in transformer, but the Ethernet (Ethernet) The bridge has the advantage of being widely used, and there is no need to install a driver when connecting to a computer device. In contrast, when the USB bridge is connected to the corresponding computer equipment, the computer equipment will detect that there is a new USB device and require the driver to be installed.

The following is a description of how the communication equipment provided by the utility model performs signal transmission and power extraction, and also describes the internal circuit and connection device of the Ethernet (Ethernet) bridge 300, so that the utility model can be removed. In addition to achieving the above purpose, it also has the effect of not needing to build a transformer and install a driver program on the computer equipment.

Please refer to FIG. 4 , which shows a block circuit diagram of the communication equipment of the present invention. Wherein the Ethernet (Ethernet) bridge 300 includes a power plug 302 and a transmission interface 301 as mentioned above, wherein the power plug 302 is coupled to a power socket in any corner of the room, and it is worth noting that the application of the power plug 302 here is It is to transmit the signal of the HomePlug on the power line, not to supply the power of the Ethernet bridge 300 . The transmission interface 301 is coupled to the shared connector 311 of the connection device 310.
