Problems solved by technology

In a special environment, the PD is overloaded or the user sets the threshold power of the equipment power supply, so that the PSE (Power Sourcing Equipment, power supply equipment) cannot work normally. At this time, the PSE equipment needs to have the ability of self-protection to deal with the overload source.
[0004] When the PSE device is connected to multiple ports to supply power to the PD, if the power required by the PD exceeds the power value that the device can provide or exceeds the value set by the administrator, the existing technology cannot automatically handle the overload source, which may cause the PSE device to damaged, causing other PDs to fail to work, causing the fault to spread

Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0050] Such as figure 1 As shown, the method for overload protection of equipment in the POE system of the present invention comprises the following steps:

[0051] Step 101: configure priority for each port supporting POE of the PSE, and set a threshold power priority variable is a variable stored in the global fixed, if the user does not artificially set, the default priority of the POE port is the lowest priority;

[0052] Step 102: detecting the real-time power of the PSE in real time;

[0053] Step 103: Determine whether the real-time power of the PSE is greater than the preset threshold power, if so, execute step 104; if not, return to step 102;

[0054] Step 104: Cut off th...

Abstract

The invention discloses a method for carrying out overload protection on equipment in a POE system. The method comprises the following steps: A, configuring the priority for each port supporting power over Ethernet (POE) of power supply equipment (PSE), and setting a threshold power; B, detecting the real-time power of the PSE, judging whether the real-time power is larger than the threshold power, and executing step C if the real-time power is larger than the threshold power; and C, cutting off the power supply at the PSE ports in an ascending order based on the priority until the real-time power is equal to or smaller than the threshold power. By setting the priority for each port of the PSE equipment, and cutting off the power supply at the PSE ports in the ascending order based on the priority when the PSE is overloaded, the invention prevents the PSE end equipment from being overloaded, and ensures the power utilization of the important PD equipment as much as possible, realizes the automatic protection set by the PSE, further reduces the equipment damage probability, and enhances the accessibility and the reliability of the equipment.

Description

technical field [0001] The invention relates to a POE technology, in particular to a method and a device for overload protection of equipment in a POE system. Background technique [0002] The full name of POE is Power Over Ethernet (Power Over Ethernet), which refers to the power supply to the Ethernet network through 10BASE-T, 100BASE-TX, 1000BASE-T and other media, and its reliable power supply distance is up to 100 meters. In this way, it can effectively solve the centralized power supply of terminals such as IP phones, wireless APs (Access Points), portable computers, portable device chargers, credit card machines, cameras, and data acquisition. It is no longer necessary to consider the wiring of its indoor power supply system, and the power supply to the equipment can be realized while connecting to the network. In terms of versatility, the current POE power supply has a unified standard. As long as the published IEEE 802.3af or IEEE 802.3at standard is followed, the ...
