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, see image 3 As shown, 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, so the power supply device 1 To have a "discovery program", the circuit design of the power supply device 1 will be quite complicated, and a higher manufacturing cost will be required

Furthermore, the current Power over Ethernet technology mainly uses RJ-45 connectors as the "Power over Ethernet connection port (PoE Port)", please refer to Figure 4 As shown, the RJ-45 connector 4 is provided with first to eighth conductors 41 to 48 in order from left to right, wherein the first to third and sixth conductors 41 to 43, 46 are used for network signal transmission, and the fourth, 5, 7 and 8 conductors 44, 45, 47, 48 transmit other signals or power, so if more other signals are needed or power is not transmitted in the manner specified by Power over Ethernet technology, all of the RJ-45 connectors 4 Conductors 41-48 cannot be used for other applications, so 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.
