POE signal switching equipment

Technical Field

The utility model relates to an electric communication technical field especially relates to a POE signal switching equipment

Background

Poe (power Over ethernet) ethernet power supply refers to a technology that can provide dc power for some IP-based terminals (such as IP phones, wireless lan access points AP, and network cameras) while transmitting data signals for such devices without any modification to the existing ethernet cat.5 wiring infrastructure.

A complete POE system comprises two parts, namely a Power Sourcing Equipment (PSE) and a Powered Device (PD). The PSE device is a power supply device for the ethernet client device and is also the administrator of the entire POE ethernet power supply process. The PD device is a PSE load receiving power supply, i.e. a client device of the POE system, such as an ethernet device like an IP phone, a network security camera, a personal digital assistant (PAD).

Low-power equipment such as lamps and lanterns can directly use POE to connect the power supply, and the wiring is simple, convenient and practical. However, the inventor found in research and practice that for a small power light fixture product of about 10W, if each light fixture has PD and PSE functions, the cost of the light fixture becomes very high, and the cost ratio of the POE circuit exceeds more than half of the total cost, which results in unacceptable customers.

Therefore, how to access the low-power device to the POE network and reduce the cost is an urgent problem to be solved.
