Intelligent radio frequency card detection device used in short distance

Abstract

The invention relates to the technical field of RFID, and discloses an intelligent radio frequency card detection device used in a short distance. The device comprises a shell, a card reading mechanism is fixedly installed at the bottom of the shell, a rotating screw is rotatably connected to the upper end of the card reading mechanism, and adjusting gears are rotatably connected to the positions,on the two sides of the rotating screw, of the upper portion of an inner cavity of the shell. Movable pieces are slidably connected to the left wall and the right wall of the inner cavity of the shell, push rods extending to the surfaces of the adjusting gears are movably connected to the movable pieces, and limiting bodies are fixedly installed at the positions, on the two sides of the card reading mechanism, of the lower portion of the inner cavity of the shell. According to the intelligent radio frequency card detection device used in the short distance, a radio frequency card is stably limited through cooperation of supporting rods and limiting springs and cooperation of limiting discs and torsional spring assemblies, the adjusting gears deflect to drive bearing discs to move along tooth sections, and therefore it is effectively guaranteed that the radio frequency card does not accidentally fall off in the detection period, and the detection effect on the radio frequency card is improved.

Description

technical field [0001] The invention relates to the technical field of RFID, in particular to an intelligent radio frequency card detection device for short-distance use. Background technique [0002] RFID technology is radio frequency identification technology, which is a non-contact two-way communication exchange data using radio frequency to achieve automatic identification technology. The radio frequency identification technology system includes at least two parts: a card reader and a radio frequency card. After the production and processing of the card is completed, it is necessary to test the stability of its ability to exchange information. During the use of the general smart radio frequency card detection device, the limit effect on the radio frequency card is poor, and the radio frequency card often falls off accidentally during the motion detection , procrastinating detection progress, in addition, when testing the information exchange capability of the radio frequ...

[0002] RFID technology is radio frequency identification technology, which is a non-contact two-way communication exchange data using radio frequency to achieve automatic identification technology. The radio frequency identification technology system includes at least two parts: a card reader and a radio frequency card. After the production and processing of the card is completed, it is necessary to test the stability of its ability to exchange information. During the use of the general smart radio frequency card detection device, the limit effect on the radio frequency card is poor, and the radio frequency card often falls off accidentally during the motion detection , procrastinating detection progress, in addition, when testing the information exchange capability of the radio frequency card by changing the orientation of the radio frequency card and the relative distance between the reader and the reader, there is still a certain gap between the simulated movement range and the real use environment, which will lead to Some radio frequency cards with minor internal manufacturing problems cannot be detected in time

[0003] Aiming at the deficiencies of the prior art, the present invention provides a short-distance smart radio frequency card detection device, which effectively ensures that the radio frequency card will not accidentally fall off during the detection period, improves the detection effect of the radio frequency card, etc. Advantages, it solves the problem that the general smart radio frequency card detection device cannot maintain a stable limit ability for the radio frequency card and the detection effect of the radio frequency card is poor during the use process
