Curtain-type intelligent safe detection device and detection method

Abstract

The invention discloses a curtain-type intelligent safe detection device and a detection method. A plurality of antennae are inlaid in a curtain, and the RF end interfaces of the antenna are connected with an antenna rotating control unit through coaxial cables; and the antenna rotating control unit is mutually connected with the RF end interface of a reader. The reader emits electromagnetic waves to the antennae and receives information sent by an identification tag near a curtain channel, and the antenna rotating control unit activates the identification tag and transfers the collected data to the reader; and the reader judges whether the identification tag is in the radiation range of the antennae or not and processes the information of the identification tag and then sends the information to a host computer, and after all the antennae carry out the detection by turns, the detection is finished. The invention effectively prevents the reading blind area, reduces the distance between people and the antennae, also can collect the required information at the signal power below 200 mW, and does not need manual monitoring during detecting.

Description

technical field [0001] The invention relates to a curtain-type safety detection device based on RFID (radio frequency identification) technology, which is applied to anti-theft detection at entrances and exits of libraries, stores and the like. Background technique [0002] In recent years, with the development of technologies such as large-scale integrated circuits, network communications and information security, RFID has entered the stage of commercial application with the characteristics of high-speed moving object recognition, multi-target recognition and non-contact recognition. In the field of security detection, RFID technology Compared with the commonly used barcode recognition technology, it has the advantages of large data volume, strong environmental adaptability, high efficiency, long reading and writing distance, changeable, and not affected by pollution and wear. When barcode identification technology is used in practice, it needs to cooperate with correspondi...

Problems solved by technology

[0003] The defect of the existing RFID safety detection device is: the reading distance of the reader is short, and there is a reading blind area

Since increasing the power of the reader will increase the amount of radiation, it may cause harm to the human body. When a person passes by the door guard, if the signal power is insufficient, it will be difficult to capture the information in the far part. If the signal power is too large, there will be energy waste and radio frequency. Pollution, therefore, the problem of reading blind spots in RFID security detection devices has not been resolved
