Embodiment
With reference to Figure of description 1, accompanying drawing 2 and accompanying drawing 3, the utility model discloses a kind of organizational structure electronic code card read-write recognizer, comprise and detect the radio frequency identification module 1 that organizational structure's electronic code is demonstrate,proved whether close also tissue receiving mechanism electronic code card information data, with the basic testing circuit 2 that is connected with described radio frequency identification module 1 and described information data is handled, described basic testing circuit 2 comprises communication transmitters and transistor amplifier, 11 of communication transmitters, 12 pin are connected to 2 of radio frequency identification module 1,3 pin acquired signal, 13 of communication transmitters, 14 pin are connected to 2 of RS232 interface, 3 pin send signal to computing machine, read and write the information that described radio frequency identification module 1 is collected by computing machine, amplify by light emitting diode 3 through transistor amplifier from the 12 pin sampling of communication transmitters therebetween and do the light signal prompting, described radio frequency identification module 1 is provided with induction antenna 4, the read-write recognizer provides power supply to supply with through induction antenna 4 for organizational structure's electronic code card, finish the data transfer to organizational structure's electronic code card simultaneously, described communication transmitters is that model is the chip of LMS202E.The read-write recognizer is demonstrate,proved through described RS232 interface connection external computer acquisition power supply and for organizational structure's electronic code induction power supply is provided.Radio frequency identification module 1 described in the utility model is radio frequency REID (Radio Frequency Identification, abbreviation RFID), and its core is to solve sharing of data acquisition and data.The RFID technology is divided into initiatively RFID, and passive RFID and half is RFID initiatively, and using maximum in the world is passive RFID.Mass transit card is exactly a kind of typical passive rfid card, it is not self-powered, produce electric energy by card reader radio frequency scanning cutting rfid card internal antenna by emission when rfid card is approaching, this electric energy is supplied with the energy that chip transmits again, chip is launched the information in the card by antenna more again, is read by card reader.
