Abstract

The embodiment of the invention provides a POE controller and a POE control system; a POE controller adopts a PWM terminal or a DC voltage terminal; the POE controller comprises a POE separator which is used for separating the DC voltage and the data, a DC / DC converter which is connected to the POE seperator, and an LED lamp which is used for converting DC voltage supplied by the POE seperator to DC high voltage and supplying the DC high voltage to an LED lamp driven by the DC voltage; the DC voltage supplied by the POE seperator is converted to the DC low voltage which is supplied to the microprocessor; an LAN module is connected to the POE seperator and the DC / DC converter; the LAN module is used for receiving the data coming from the POE seperator and transmitting the data to the microprocessor; the microprocessor is connected to the DC / DC converter and the LAN module for executing the data coming from the LAN module and generating a corresponding control signal to control the LED lamp.

Description

technical field [0001] The invention relates to the technical field of POE control, in particular to a POE controller and a POE control system. Background technique [0002] Power Over Ethernet (POE) is a local area network (LocalAreaNetwork, LAN) based power supply system. POE uses existing standard Ethernet transmission cables to transmit data and power at the same time, and maintains the compatibility of existing Ethernet systems and users. POE uses LAN to transmit data and electric power to devices at the same time, which can reduce the number of cables used for communication and power supply. [0003] One application scenario of POE is POE control LED light system. Through the LAN cable, the control signal and electric power are used to control the LED lights. However, in some practical cases, LAN cables cannot be installed. [0004] In addition, in the prior art, one POE controller in the POE control system can only be connected to one LED lamp. For relatively larg...
