Embodiment
Combine accompanying drawing that the utility model is done further explain through embodiment below.
Please refer to Fig. 1, shown the proving installation among a kind of embodiment, this proving installation comprises with lower module at least: Non-contact Media Reader, control module, linkage unit, shielding box; Non-contact Media Reader is used for sticking into capable radio communication with tested, and sends data to control module; Control module is controlled tested card through linkage unit, and the tested row that sticks into is supplied power and data acquisition; Control module also can be connected to Non-contact Media Reader simultaneously, is used to receive handle the data message that Non-contact Media Reader sends, and Non-contact Media Reader is supplied power; Non-contact Media Reader and tested card are positioned in the shielding box to be tested, and shielding box is used for the undesired signal of screening effect test data accuracy.
Further; The utility model device has also comprised the PC/SC card reader; PC/SC is personal computer (Personal computer)/smart card (Smart Card); The PC/SC card reader is a Standard User interface (API) based on the WINDOWS platform; Be a kind of normal structure that smart card access windows platform (comprising Windows 2000) defines, linkage unit is connected to tested SIM on the PC/SC card reader, and the control module that the other end connected through the PC/SC card reader realizes control and power supply function to tested SIM.
Further, this can also be provided with deck on linkage unit on the utility model device, in test, can tested card be positioned in the deck, carries out the communication test with card reader, can carry out wired data communication through deck and control module.
Further, Non-contact Media Reader links to each other with said control module through USB commentaries on classics serial port connecting wire, and the data of card reader being tested through USB commentaries on classics serial port connecting wire send to control module analysis, handle.
In one embodiment; Shielding box in the utility model can be through covering one deck absorbing material on the inwall of box body; Realize effect that test is shielded the undesired signal that has influence on test; Guaranteed the test data accuracy in the test process; Simultaneously can reinforce, seal it through fastening unit in the outside of shielding box, not receive the influence of extraneous undesired signal when guaranteeing further to test in deck and the Non-contact Media Reader shielding box, wherein fastening unit can be a screw.
In concrete implementation process; With Non-contact Media Reader is that RFID-SIM card reader and deck are arranged in the shielding box; Drawing USB from the bottom of box body changes Serial Port Line connection RFID-SIM card reader and control module PC end, and the PC interface end of PC/SC card reader is connected on the control module PC, then 7816 interface signal CC plates is inserted the SC end of card reader; Tested SIM is put into deck after having downloaded corresponding testing program; Be connected on 7816 circuit boards through deck, and receive power supply and the control of control module PC, treat that tested SIM powers on and promptly begin test after the success; Need not do other any operations again, test result can print demonstration through control module PC serial ports.
When utilizing the utility model to test, as shown in Figure 2, be specially, earlier test environment is calibrated, utilize reference card during calibration, measure the verification level value of reference card simultaneously; Non-contact Media Reader sends the field signal of low frequency to tested card; The low frequency magnetic field signal that tested card receiver card reader is sent, and measure the low-frequency level value of tested card.In the whether qualified process of the tested card of evaluation, can contrast the verification level value of low-frequency level value and the reference card of tested card, if the result of contrast in the scope of setting, the judgement of then tested card quilt is qualified; When the result who contrasts has exceeded preset scope, judge that then tested card is defective.
