Laboratory equipment dynamic management system based on passive RFID

Abstract

The invention provides a laboratory equipment dynamic management system based on passive RFID. The laboratory equipment dynamic management system based on the passive RFID comprises multiple passive RFID tags, multiple locating reader-writers, an access control / borrowing and returning reader-writer and an application server. Each passive RFID tag has a unique ID number. All the passive RFID tags are pasted on laboratory equipment. All the locating reader-writers are installed in a laboratory, and radio frequency signals of each locating reader-writer cover the whole laboratory. The access control / borrowing and returning reader-writer is installed close to a door in the laboratory. The application server is provided with a tag writing module, a setting module, a query module, a borrowing and returning equipment module, a locating module and a database. The laboratory equipment dynamic management system based on the passive RFID solves the existing problems that laboratory equipment is overstocked and searching is aimless, can monitor the flow direction of the equipment, manage equipment information and facilitate searching in real time and saves manpower and material resources, and the position of the searched equipment can be easily and quickly determined in the laboratory.

Description

technical field [0001] The invention relates to the field of radio frequency technology, in particular to a dynamic management system for laboratory equipment based on passive RFID. Background technique [0002] Instruments and equipment are indispensable tools for institutions of higher learning to complete teaching tasks and scientific research projects. Therefore, they occupy a particularly important position in the management of teaching and funds in institutions of higher learning. The standard and orderly management of instruments and equipment is the basic condition to ensure the smooth progress of teaching tasks and scientific research projects. National key universities invest a lot of money in the introduction of equipment and equipment every year, but the traditional management method is too dependent on labor, lacking a reasonable management method, coupled with the large purchase of their own laboratory equipment, lack of unified management, resulting in a backl...

Problems solved by technology

Mature positioning systems include: RADAR, SpotON, and LANDMARC. RADAR establishes a signal characteristic database of reference nodes through experiments, and performs signal matching to complete positioning during on-site measurement. The distance of the tag is to be determined, and finally use the positioning algorithm to locate the target in three-dimensional space; LANDMARC is a relatively mature positioning technology at present. Its principle is to set a reference tag on a two-dimensional plane. Note that the closer the target label is to the reference label, the positioning is achieved. This method can effectively avoid the influence of various factors in the space environment, but the positioning in the three-dimensional space has limitations.
