Integrated testing device for power supply characteristics of PSE equipment

Abstract

The invention relates to an integrated testing device for power supply characteristics of PSE equipment. The device comprises a display unit and more than one power test group, the more than one electric power test group is in communication connection with the display unit. Each of the more than one electric power test group comprises an electric power detection assembly and a separation assemblyused for separating electric power output by PSE in a mixed manner from Ethernet data. The power detection assembly is electrically connected with the separation assembly, the power detection assemblycomprises an acquisition unit and a load unit, the load unit is electrically connected with the separation assembly, the acquisition unit is arranged on a circuit where the load unit is connected with the separation assembly, and the acquisition unit is in communication connection with the display unit. After a plurality of ports of the PSE equipment are respectively connected with a plurality ofseparation assemblies, the simultaneous detection of the plurality of ports of the PSE equipment can be realized through the test of a plurality of power test groups. Through the arrangement of the display unit, the real-time display of the power characteristics of each port of the PSE equipment is realized, so that the visibility of the power characteristics of the PSE equipment is better.

Description

technical field [0001] The invention belongs to the technical field of equipment power supply characteristic detection, and in particular relates to an integrated test device for the power supply characteristic of PSE equipment. Background technique [0002] POE refers to the transmission of data for some IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras, etc.) without any changes to the existing Ethernet wiring infrastructure. Technology that can provide DC power for such devices. PSE is a device that uses POE technology to supply power to such terminals. A complete POE system includes two parts: the power supply equipment (PSE, Power Sourcing Equipment) and the power receiving equipment (PD, Powered Device). [0003] The key test indicators of PSE equipment are: working output voltage, working output current, maximum output current, output power, overall power and data transmission. [0004] The traditional method of testing PSE equip...

Problems solved by technology

[0004] The traditional method of testing PSE equipment is to connect the PD to the PSE through an Ethernet cable, measure the power indicators such as the output voltage and output current of the Ethernet cable through a multimeter, and test data transmission by managing and running the PD equipment. This method has the following effects on test efficiency. Disadvantages of test quality and test quality: 1. The rated power of PD equipment is fixed. In order to test the ability of PSE equipment to supply power to PDs with different powers, a large number of PDs with different powers must be prepared; 3. When the PSE device has a large number of ports that support POE, then when the whole machine is tested, the above two disadvantages will be further magnified, and the test time will increase exponentially.
