Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described further.
A kind of Wireless Telecom Equipment based on NFC (Fig. 1), including handhold read-write equipment 10 and movable storage device 11;
Handhold read-write equipment 10 (Fig. 2) includes control chip 1, input module 2 and output module 3, and power module, control chip 1 is connected to NFC read write line 4 by SPI interface, input module 2 is connected with control chip 1 by multiple I/O interfaces, and output module 3 is connected with control chip 1 by parallel interface 9; Movable storage device 11 includes at least one NFC label chip 12;
NFC read write line 4 and NFC label chip 12 are provided with the antenna being mutually matched, what be arranged at NFC read write line 4 is antenna 1, what be connected to NFC label chip 12 is antenna 28, is carried out the transmission of information between antenna 1 and antenna 28 by electromagnetic induction coupled modes. NFC read write line 4 and NFC label chip 12 adopt passive communication mode, and NFC read write line 4 opens magnetic field, and label obtains work capacity from the magnetic field of transmission, then pass through modulation magnetic field and transfer data to NFC read write line 4.
Control chip 1 is connected to flash storage 5 and SD card 6 also by SPI interface. Control chip 1 is also associated with USB interface, and USB interface is to the interface of lithium cell charging, also can insert on computers, and SD is directly carried out the read-write of data by computer.
Power module connects respectively at control chip 1, output module 3 namely LCDs, flash storage 5 and SD card 6.
The control chip 1 of the present embodiment adopts the STM32F103VET6 chip of ARM company, NFC read write line 4 adopts CR95HF read write line, and the chip of CR95HF read write line supports wireless communication protocol ISO/IEC15693, ISO/IEC14443TypeAandB, ISO/IEC18092. Flash storage 5 chip adopts W25Q64, and the resolution of LCDs is 480 × 320, and SD card amount of capacity is 4G, and control chip 1 is also associated with USB interface 7.
After the device of the present embodiment starts, the LCDs display starting-up interface of handhold read-write equipment 10, user carries out function selecting by input module 2 matrix press-key.
When selecting operation NFC read write line 4, control chip 1 carries out data communication by SPI interface and NFC read write line 4, first NFC read write line 4 initializes, then carry out agreement selection and then open magnetic field, magnetic field can power to the NFC label chip 12 in movable storage device 11 in the way of the coupling of magnetic field, so that NFC label chip 12 can normal operation. NFC read write line 4 is after opening magnetic field, just carry out the search of NFC label chip 12, carry out anti-collision inspection, if searching NFC label chip 12, and only one of which NFC label chip 12, just can return the ID of NFC label chip 12, next in conjunction with the read write command of NFC label chip 12, just by the communication mode of NFC, the memory area of NFC label chip 12 can be carried out the read-write of data, after having read and write, just can closing magnetic field, operation completes.
User passes through button operation control chip 1, control chip 1 is processed by SPI interface, stores to NFC read write line 4 and then to the data on NFC label chip 12, completing storage and the communication function of data, controller is read the data on NFC label chip 12 and is exported to user by LCDs simultaneously.
