Title: Guirong Ji: Innovator in Power Supply Detection Technology

Introduction

Guirong Ji is a notable inventor based in Shenzhen, China. He has made significant contributions to the field of power supply detection technology, holding two patents that showcase his innovative approach to enhancing power sourcing equipment.

Latest Patents

Guirong Ji's latest patents include a "Power supply detection apparatus and method for detecting power to a power over ethernet device." This invention features a power sourcing equipment (PSE) circuit, a power supply module, and a reverse circuit. The PSE circuit is designed to send a first and second sounding electrical signal to the reverse circuit. The reverse circuit outputs the first sounding electrical signal to a wire-pair group of an Ethernet cable and performs reverse processing on the second sounding electrical signal. The PSE circuit determines the forward and reverse sounding results of a to-be-detected device, identifying it as a non-PD when either result indicates a short circuit.

Another patent is the "Connection manner identification method, power sourcing equipment, powered device, and storage medium." This method involves the power sourcing equipment sending load adjustment indications to powered devices through data ports. Each indication prompts a corresponding powered device to adjust its load. The powered devices are connected to the power supply ports and data ports of the power sourcing equipment. The equipment then analyzes output power changes to determine which data port and power supply port are linked to the same powered device.
