[Previous technology] In the past, network equipment usually used two independent wires for transmission of "data" and "F power". The wires for transmitting data usually used magic ^ connectors and four pairs of twisted pairs. (Twlsted palr) combination, however, because two pairs of twisted pairs are used for data transmission /, four pins on the RJ_45 connector (pins 4, 5, 7, and 8) and two pairs The twisted pair was left idle, so in order to make full use of it: Seeing some π-prepared sources of poverty, and for the convenience of use, the industry has developed the "Power Network Technology" (PGwer GverEtheraet; ρ〇Ε). The original intention was to use the idle, nibble, and double red wires for power transmission. In this way, the network equipment no longer needs an external power supply, and the required power can be unified-supplied by a central network device and the central network device can be equipped with a UPS (Uninterruptible Power System) to ensure power failure. Alas, all network devices connected to it can work normally. Due to the incompatibility of M, power Internet technology has gradually become a necessary culprit for wireless network base ports. Because of the characteristics of wireless networks, it is often necessary to place the base station in an empty space to strengthen the receiving range. These places are usually not designed with power outlets. If this is not the case, the extra power outlets must be installed. With JH, female σ rose dagger, one makes the installation of the base station unlimited:: =. However, the use of power to access the Internet technology is possible. However, the traditional two; network equipment does not support electricity, to some problems, such as if the central equipment provided by the most advanced technology '^ required power is greater than the central network equipment', t Keeping traditional central network equipment today is not what you need. [Summary of the Invention] State-of-the-art devices can be supplied by the city electricity at the same time. The main purpose of this task is to provide one kind of power injection, two kinds of f-force sources, etc .... The flexibility. End-of-purpose supply-a kind of electric power injection device, which can avoid terminal equipment failure caused by the power of the terminal is larger than the network switch or hub. Source according to the above-mentioned purpose, the present invention provides -A kind of power injection device can provide two kinds of power sources for the terminal equipment. The power source is transmitted by Ethernet and the power source is supplied by the city electricity. Therefore, when the power required by the terminal equipment is greater than the network switch or hub H When the maximum power supply is provided, this terminal device can choose to be powered by the city power source, so it can avoid the terminal device being unusable due to insufficient power, and within the scope of the terminal device's license, it can also choose to be transmitted by Ethernet. [Embodiment] 1221061 Without limiting the spirit and scope of the present invention, the following is an example to introduce the implementation of the present invention. Those skilled in the art will understand the spirit of the present invention and understand it. The power injector device of the present invention is applied to various network systems. The power injector device of the present invention can provide two kinds of power at the same time. The power source is a source of power transmitted by the network and a source of power supplied by the city power supply. Therefore, the power injector of the present invention can avoid that the power required by the terminal equipment is greater than the maximum power source provided by the network switch or hub, causing the terminal The device cannot be used. The application of the present invention is not limited to the preferred embodiments described below. Referring to the first figure, it is a schematic diagram of a power injector according to the first embodiment of the present invention. The power injector 100 has two RJ-45 (Registered Jack-45) connectors 102 and 104. When RJ-45 connector 102 receives the data signal transmitted by an Ethernet network, it will connect another RJ-45 connector 104, and this RJ- 45 connector 104 is used to provide the connection of terminal equipment, wherein the terminal equipment can be an Internet phone (Voice over IP, VOIP), a wireless network connector (Access Point) or other network equipment. A conductive Line 108 can couple the power provided by AC mains 110 to this RJ-45 connector 104, and this RJ-45 connector 104 and an 8-wire twisted pair will simultaneously carry data and power, where power and data are used separately among them Different twisted pairs are used for transmission. Referring again to the first figure, another power source provided by the power injector 100 of the present invention is provided by the AC mains 110. The AC power provided by the AC mains 110 is provided by the present invention. After the transformer 112 and rectifier 114 are rectified into DC power, the noise is filtered by the filter 116, and then passed through a fuse 118 to avoid damage to the terminal equipment caused by excessive current injection, and an EMI filter to prevent electromagnetic interference. 8 1221061 After the connector 120, in addition to outputting power to subsequent terminal devices via the DCMaek 122 connector, it also provides power to the RJ_45 connector 104 via a conductive wire 108, allowing the eight wires of the RJ-45 connector 104 to be connected Among the twisted pairs, 4 wires can transmit data, and the other 4 wires can transmit power to subsequent terminal equipment. The connector 122 is a DC socket. When using the above-mentioned power injector device 100, the user's subsequent terminal equipment can choose to connect RJ-45 connector 104 or connector 122, in other words, if the user's final i% 5 and With support for Internet technology, you can choose to connect RJ-45 connector 104 to receive data and power at the same time. Conversely, if the terminal equipment used does not support network power, then you can choose to connect the connector 122 to provide power and use another transmission line to transmit data. Please refer to "The first picture is not a schematic diagram of the first embodiment of the present invention, using a power injector: a schematic diagram for supplying power to a terminal device, where the terminal device 200 can be a Voice over IP, VOIP), wireless network connector (Access point) or other network equipment. Assume that if this terminal device supports the power Internet technology, then the RJ-45 connector 204 of the terminal device 200 can be connected to the RJ-45 connector 104 of the power injector 100 of the present invention via an eight-wire twisted pair 300. Data and power are obtained simultaneously through the eight-wire twisted pair 300, and the data and power are transmitted through different four-wire twisted pairs respectively. The obtained power will pass through an EMI filter 206, a rectifier 208, and a fuse 21 to prevent electromagnetic interference. Avoid excessive current injection to damage terminal equipment, a current limiting circuit 212 to prevent inrush current, and a detection. A circuit 214 and a switching power supply 216 are provided to the terminal equipment. The detection circuit 214 is used to verify whether the terminal equipment complies with the power grid technology 9 1221061 technology. When the power supply terminal that complies with the power grid technology confirms through the detection circuit 214 that the power receiving characteristics of the terminal equipment meet the requirements of POE, The power output can be sent to this terminal device. The design of the parent switchable power supply 216 can be selected from flyback design, forward design, push_pull design, and half bridge design. -bridge) or full bridge (FuU_bridge) design. The 7F wire in the second picture shows the schematic diagram of the power injector that provides power to the terminal device according to the first embodiment of the present invention, wherein the terminal device can be a Voice over IP (VOIP) 'wireless network connector ⑽ss ㈣ or other network equipment. Assume that this terminal device does not support the Internet access technology. The connector 218 of the terminal device 200 is connected to the connector 122 of the present invention through an electrical thin wire 302 and is powered by the mains power. Another Ethernet network (not shown in the figure) (Shown) The RJ-45 connector 204 that will be connected to this terminal device is used to transmit data. In other words, when the terminal device does not support the power Internet technology, the AC mains power can be directly selected through the present invention. The transformer is used to stabilize the voltage of the terminal equipment, so it does not require an adapter (Adimtrvr, m > k Adaptor), so it is more cost-effective in architecture. _ 7 丨 The team exploded a schematic diagram of the power injector 400 of the Mingming ’s two-pronged example. In this embodiment, an RJ-45 connector 102 after receiving a data signal can also be used with a dissipator 106, and The other RJ_45 connector 10 is connected ... connected to the conductive wire of the 1G6 coupler. The power provided by the AC mains 11G is transmitted to the coupler 106, and fed to the RJ_45 connector 1 through the coupler 106. 4. At this time, power and data are combined in the same twisted pair for transmission to the terminal. 10 1221061 When using the above-mentioned power injector device 400, the user's subsequent terminal equipment can also choose to connect RJ-45 connector 104 or connector 122. In other words, if the terminal equipment used by the user supports power When using Internet technology, you can choose to connect RJ-45 connector 104 at this time to receive data and power at the same time. Conversely, if the terminal equipment used does not support the power Internet technology, you can choose to connect the connector 122 to provide power, and use another transmission line to transmit data. Referring to FIG. 5, a schematic diagram of a φ power supply provided by a power injector according to a second embodiment of the present invention to a terminal device is shown. The terminal device supports a power internet technology, and the terminal device 200 may be an Internet phone (Voice over IP (VOIP), wireless network connector (Access Point) or other network equipment. At this time, the RJ-45 connector 204 of the terminal device 200 can be connected to the RJ-45 connector 104 of the power injector 100 of the present invention via the twisted pair 300, and the data and power can be obtained simultaneously through the twisted pair 300, and The transmitted data and power are coupled together and transmitted over the same twisted pair. At this time, the biggest difference from using the power injector of the first embodiment is that the transmitted data and power are coupled together, so the RJ-45 connector 204 of this terminal device 200 and the EMI filter for preventing electromagnetic interference In 206, a decoupler 220 is required to decouple the data transmitted simultaneously through the twisted pair 300 from the power. In summary, the power injector of the present invention can provide two types of power sources for terminal equipment at the same time, one is the power source transmitted by Ethernet, and the other is the power source supplied by the city electricity. When the maximum power source provided by the circuit switch or hub is provided, this terminal device can choose to be supplied by the mains power source, so it can avoid the terminal device being unusable due to insufficient power. The Ethernet transmits the power source, so it can increase the flexibility of using 11.
