Abstract

The invention discloses an adjustable power network power receiving circuit and equipment. The adjustable power network power receiving circuit includes: a POE data power supply separation module, a POE protocol module, a power switch module, a load power control module and a controller; The POE data power supply separation module is used to separate data and power from the output of the POE power supply equipment; the POE protocol module provides POE protocol detection for the POE power supply equipment; the power switch module is used to control the load power The module and the controller control the power supply switch; the load power control module generates adjustable power under the action of the controller. The adjustable power network power receiving circuit and equipment realize precise control of load power through the controller, so that the load power can be adjusted from 0.44W to 33W.

Description

technical field [0001] The invention relates to the technical field of active Ethernet, in particular to an adjustable power network power receiving circuit and equipment. Background technique [0002] Today, with the increasing popularity of the network, POE (Power Over Ethernet) centralized power supply is favored by business and enterprise users. However, it is not very convenient for testing POE equipment. [0003] There are mainly two existing test schemes: one is to use a PD (Powered Device) on the market as the test load. However, the power of corresponding PD devices on the market is relatively low, most of which are lower than 20W. However, the standard power of IEEE802.3AF specification is 30W, which makes it impossible for POE equipment manufacturers to run the test at full load during the generation test of the equipment. Another option is to use a cement resistance test load. Since the power of cement varies with the power supply voltage, the accuracy of the...
