The invention relates to the technical field of electronics, and discloses a POE power supply system comprising a POE chip and a PHY chip, wherein the POE chip comprises 25 pins, the 25 pins of the POE chip are correspondingly connected with pins of an isolation transformer module one by one, the POE chip is connected with a 24.3K resistor in series, a network interface comprises 8 pins, the 8 pins of the network interface are also correspondingly connected with the pins of the POE chip one by one, PD equipment is connected with the network interface via a network cable, the PHY chip is used for detecting the type of the network cable, the POE chip is used for supplying power to PD equipment that the network interface accesses, and when the PD equipment on a receiving end is detected, thePSE equipment classifies the PD equipment, and assesses power loss needed by the PD equipment. According to the system, the tedious power supply wiring is no longer needed, the equipment power supplyconstruction and maintenance fees are omitted, the system is safe and reliable, a network lightning protection module is added, the network cable does not exceed 100m, and the induced electromotive force that damages electronic components is not easy to form.
Description
technical field [0001] The present invention relates to the field of electronic technology, in particular to a POE power supply system. Background technique [0002] POE (Power Over Ethernet) refers to the use of IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras) without any changes to the existing Ethernet Cat. etc.) while transmitting data signals, it can also provide DC power supply technology for such devices. POE is also known as local area network-based power supply system (POL, Power over LAN) or active Ethernet (Active Ethernet), sometimes referred to as Ethernet power supply, which is the use of existing standard Ethernet transmission cables to transmit data and The latest standard specification of electrical power, and maintain compatibility with existing Ethernet systems and users. POE technology can guarantee the normal operation of the existing network while ensuring the security of the existing structured wiring, and minimi...
