At least one connection port is arranged on at least one power supply device and at least one electric device; a first independent conductor is arranged in the position on the surface of each connection port close to one side thereof; a second independent conductor is arranged in the position on the surface of each connection port close to the other side thereof; the second independent conductor and the first independent conductor form a power supply circuit for transmitting power supply, a first differential signal set, a second differential signal set, a third differential signal set and a fourth differential signal set are arranged on the surfaces of the connection ports between the first independent conductor and the second independent conductor; each differential signal pair is composed of two conductors arranged on the surfaces of the connection ports; each connection port of the power supply device and each connection port of the electric device are connected together via a transmission line; a wire is arranged inside each transmission line among the first independent conductors on the power supply device and the electric device, among the second independent conductor on the power supply device and the electric device, and between each differential signal pairs.

Description

technical field [0001] The present invention relates to a network system and its connection ports for transmitting various signals and power sources, especially to an old electrical device that can transmit Ethernet signals, power sources and other network signals through a connection port without Ethernet power supply technology If the 8P8C connection port is plugged into the connection port, the old electrical equipment will not be damaged and can continue to transmit Ethernet signals. Background technique [0002] Any traditional electrical device that needs to be connected to the Ethernet network, such as IP phones, network cameras, wireless bridges, cash registers, security access and monitoring systems, etc., needs to use batteries, or have a device on the terminal network device. The power cord and power socket are used to provide the power required by traditional electrical devices. However, a better way to supply power is to transmit power and data to the electrica...

Problems solved by technology

[0006] However, for the circuit of the "Discovery program" of the power supply device 1, if the power supply device has 48 "Power over Ethernet connection ports (PoE Port)", it must be provided with 12 groups of Power over Ethernet control units 3, Please refer to Fig. 3, and each group of Power over Ethernet control unit 3 includes a Power over Ethernet controller 30 and four independent metal oxide semiconductor field effect transistors (MOSFET) 32, and controls four connection ports respectively, Therefore, the power supply device 1 must have a "discovery (Discovery) program", the circuit design of the power supply device 1 will be quite complicated, and higher manufacturing costs will be required.

Furthermore, the current Power over Ethernet technology mainly uses RJ-45 connectors as "PoE Ports". Please refer to FIG. 4, the RJ-45 connectors 4 are in order from left to right. The 1st to 8th conductors 41 to 48 are provided, among which the 1st to 3rd and 6th conductors 41 to 43 and 46 are used for network signal transmission, and the 4th, 5th, 7th and 8th conductors 44, 45, 47 and 48 are used to transmit other signals or power supply, so if more other signals are needed or the power supply is not transmitted in the way specified by the Power over Ethernet technology, all conductors 41-48 in the RJ-45 connector 4 cannot be used for other applications, so there are It is necessary to research and develop a novel technology to solve the problems of traditional circuit design complexity, high manufacturing cost, and no additional conductors can be used.
