RFID (Radiofrequency Identification) linear array personnel location and monitor system and distribution type personnel location and monitor method

Abstract

The invention relates to RFID (Radiofrequency Identification) linear array personnel location and monitor system and method. The system comprises ultrahigh frequency RFID label arrays fixedly distributed under the ground of a monitor area, linear monitor antennas arranged between two adjacent rows of label linear arrays and a monitor control device which is connected with the monitor antennas. The method comprises the following steps of establishing a standard matrix table by numbering and locating RFID labels in the RFID label arrays one by one, probing and reading the RFID labels in an electric wave covering area, calculating the amount and the positions of personnel in the RFID label arrays according to the positions and the amount of RFID labels which can not be read and a fixed distribution interval of two adjacent RFID labels; and calculating the personnel moving direction and speed according to the sequence and the time interval for not reading the RFID labels. For being adopted, the RFID linear array personnel location and monitor system and method can efficiently locate and monitor the personnel, realize lower cost, have stable and reliable work performance and wider application range and lay solid foundation for further popularizing and developing an area location and monitor technology.

Description

technical field [0001] The invention relates to the technical field of RFID radio frequency identification, in particular to the technical field of RFID monitoring and positioning, and specifically refers to an RFID linear array personnel positioning monitoring system and a distributed personnel positioning monitoring method. Background technique [0002] RFID (Radio Frequency Identification) is a radio frequency identification technology. Since the electromagnetic waves of UHF (400MHz~2.4GHz) RFID tags are easily absorbed by water and attenuated, in actual use, they are often affected by liquid containers or rich in water. The occlusion of substances (such as high water content items, human body, animal body, etc.) will cause the situation that UHF RFID tags cannot be read. [0003] At the same time, in modern life, there are already various navigation and positioning devices, such as GPS, etc., but the cost of these devices and the operating cost of the system are relative...

[0002] RFID (Radio Frequency Identification) is a radio frequency identification technology. Since the electromagnetic waves of UHF (400MHz~2.4GHz) RFID tags are easily absorbed by water and attenuated, in actual use, they are often affected by liquid containers or rich in water. The occlusion of substances (such as high water content items, human body, animal body, etc.), resulting in the situation that UHF RFID tags cannot be read

[0003] At the same time, in modern life, there are already various navigation and positioning devices, such as GPS, etc., but the cost of these devices and the operating cost of the system are relatively high

Especially for the positioning monitoring system of people or objects in the area, there is no good technology that can be popularized and applied on a large scale, which brings great inconvenience to people's work and life.
