Description
Technical Field
The application relates to the technical field of wired network accessories, in particular to a crystal head and a network connecting line.
Background
Power over ethernet systems refer to power supplied over the commonly used twisted pair lines for voice, data and video. The Ethernet power supply technology can ensure that data signals are transmitted to an IP terminal on the basis of the existing Ethernet wiring, and simultaneously provides direct current power supply for the equipment. The universal Ethernet cable is used for simultaneously transmitting the Ethernet signal and the direct current power supply, the power supply and the data are integrated in the same wired system, and the normal operation of the network is ensured while the safety of the existing structured wiring is ensured. The power over Ethernet adopts the standard of IEEE802.3af/at/bt, and 802.3af/at/bt breaks through the application of Ethernet, but it is mainly a power transmission protocol, not a data transmission protocol.
In the prior art, POE (Power Over ethernet) and spoe (simple Power Over ethernet) are generally adopted in the ethernet Power supply system, and POE refers to a network switch that supplies Power while providing network signal transmission for a front-end device (PD) through 8-core hyper-five network cables. The existing POE switch adopts the 1 st and 2 nd (or 4 th and 5 th) pairs of 8-core network cables as the positive poles of a power supply, adopts the 3 rd and 6 th (or 7 th and 8 th) pairs of negative poles of the power supply, and has a power supply voltage value of 48V. The SPOE network power supply switch adopts 9-22V power adapter input, transmits network signals for front-end equipment through 1-2-3-6 wire pairs of 8-core network wires, and supplies power for front-end equipment through 4-5 wire pairs of anodes and 7-8 wire pairs of cathodes. The SPOE network power supply switch can flexibly select a 9-22V power adapter according to the voltage required by the front-end equipment. For example, 12V power input is commonly adopted by a network camera and a wireless AP, and a power adapter of 13V-15V (the front-end equipment actually obtains 10-14V working voltage after line loss voltage reduction) can be selected as an SPOE network power supply switch. The front-end equipment needs 9V power supply, and can be provided with 10V-12V power supply for the SPOE network power supply switch. Compared with the traditional strong and weak current hybrid wiring mode, the SPOE network only needs to be provided with one network cable for power supply, so that the cable and construction cost are saved, and the construction difficulty is reduced; meanwhile, the low-voltage power supply of 9V-22V is adopted, so that potential safety hazards such as strong current interference, short circuit flammability, human injury caused by electric leakage and the like are avoided.
However, in the conventional power over ethernet system, neither "PSE providing power source" nor "PD receiving device" clearly indicates the power supply level of the link, so that the power supply voltage of the power supply device cannot be determined, in other words, the power supply voltage value provided by the power supply device in the power over ethernet system cannot be confirmed in the prior art.
