Passive ultrahigh frequency RFID vehicle-mounted on-site check system

Abstract

The invention relates to a passive ultrahigh frequency RFID vehicle-mounted on-site check system, belonging to the technical field of RFID. The system comprises a vehicle-mounted main system and a plurality of temporary distributed sub-systems. The system has RFID information read-write function, image information shooting function, alarm and hint function, control investigation function and data transmission function. The combination of the vehicle-mounted main system and a plurality of temporary distributed sub-systems are used for carrying out closed entrance/exit management. The system can realize network interconnection cooperation with a backstage command centre to secure peripheral stretch of a certain area managed by the backstage command centre and strengthen timeliness of managed objects in a mobile manner. The system has the advantages of easy operation, convenient maintenance and strong mobility, solves practical problems of a fixed system, such as high site requirement, long construction period and high cost, and practical problems of a handheld system, such as short recognition distance and single function, and is suitable for conducting fast network interconnection and checking vehicles, persons and material in unexpected emergencies or public security events.

Description

technical field [0001] The invention belongs to the field of radio frequency identification (RFID) technology, and specifically relates to a vehicle-mounted system that adopts passive ultra-high frequency RFID technology to implement on-site inspection of vehicles, personnel and materials. At the same time, the system can be realized through the joint work of the main system and the distributed subsystem. Area closed access control function. Background technique [0002] Radio frequency identification technology uses radio frequency to carry out non-contact two-way data communication to realize non-contact automatic identification of marked objects. This technology overcomes the limitation of line of sight effect, completes information input and processing without intervention, is anti-fouling, and can be processed in batches. , automation, and modern technical features. According to the working frequency, RFID equipment can be divided into low frequency (LF), high frequenc...
