Abstract
The utility model relates to a Bluetooth wireless memory, which comprises a flash memory, a processor, a Bluetooth chip and an antenna. The Bluetooth chip receives data from any Bluetooth enabled device through the antenna and transmits the data to the process through an asynchronous serial data cable. The processor processes the data and then transmits them vial the data cable and address cable to the flash memory for storage. Moreover, the processor can read data from the flash memory and transmits them to the Bluetooth chip through the asynchronous data cable. The Bluetooth chip receives the data vial the asynchronous serial data cable and transmits them to the Bluetooth device through the antenna. The Bluetooth chip communicates with the processor through I/O interfaces. The utility model provides wireless storage function to mobile phones, computers, PDAs and digital cameras. It has the advantages of small footprint, convenient carriage, large storage capability and convenient usage.

Technical background
Bluetooth (Bluetooth) is the short distance radio communication standards of being developed jointly by mobile operator and mobile computing company, is a kind of small-sized, economic, the short-range Radio Link of setting up between portable computer, mobile phone and other mobile device.The frequency range of this regulation and stipulation work is public ISM band, and peak data rate can reach 1Mbps.Utilize the equipment of Bluetooth technology communication to spread all trades and professions at present, as mobile phone, notebook, PDA, digital camera etc.These equipment are by Bluetooth technology wirelessly transmitting data easily.
Use flash memory device in signal conditioning package widely, a large amount of uses is the flash memory device that utilizes USB (universal serial bus) (USB) and memory chip technology, i.e. flash disk at present.From flash disk is born certainly, because of advantages such as it need not complex drive mechanism, volume is little, easy to carry, memory space is big, easy to use are widely used.
But flash disk uses USB interface and computing machine to communicate, and can't not use on mobile phone, PDA, digital camera etc. do not have the hand-held mobile terminal of USB interface, has limited the usable range of this flash memory device of flash disk.
The content of utility model
Need use USB interface and computing machine to communicate at existing flash disk, can't not have the deficiency of using on the hand-held mobile terminal of USB interface at mobile phone, PDA, digital camera etc., the purpose of this utility model provides a kind of novel blue-tooth radio memory.
The purpose of this utility model is achieved in that a kind of blue-tooth radio memory, comprises flash memory, processor, Bluetooth chip and antenna; Bluetooth chip is by the data of antenna receiving belt bluetooth function device, send to processor by the asynchronous serial data line, after the processor processing by data line and address wire with data storage in flash memory, perhaps processor reading of data from flash memory sends to Bluetooth chip by the asynchronous serial data line again, Bluetooth chip is given described bluetooth equipment by antenna transmission after the asynchronous serial data line is received data.
Its hardware annexation is that processor passes through address wire, data line links to each other with flash memory (Flash Memory), and Bluetooth chip links to each other with processor with the I/O mouth by the asynchronous serial data line, and antenna links to each other with Bluetooth chip by radio frequency line.Described Bluetooth chip carries out data communication by asynchronous serial data line and processor; Bluetooth chip carries out the state communication by I/O mouth and processor; Processor is by address wire and data line and flash memory communication.
The utility model is reasonable in design, simple in structure, has advantages such as volume is little, easy to carry, memory space is big, easy to use, and need not complex drive mechanism; Utilize the Bluetooth wireless transmission technology that the equipment that flash memory device and mobile phone, computing machine, PDA or digital camera etc. have Bluetooth function is carried out data transmission, for equipment such as mobile phone, computing machine, PDA, digital camera provide wireless memory function.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is the utility model structural principle block scheme.
Among Fig. 1: 10-flash memory, 11-processor, 12-Bluetooth chip, 13-antenna.
Embodiment
Below in conjunction with accompanying drawing, explain preferred embodiment of the present utility model in detail.In the process of explaining, omit description to known function and structure.
As shown in Figure 1, Bluetooth chip 12 receives other bluetooth equipments by antenna 13, as data with mobile phone, computing machine, PDA or the digital camera etc. of Bluetooth function, send to processor (MCU) 11 by the asynchronous serial data line, after handling, data storage is arrived in the flash memory (FlashMemory) 10 MCU by data line and address wire, perhaps reading of data sends to Bluetooth chip 12 by the asynchronous serial data line again from flash memory (Flash Memory) 10, Bluetooth chip 12 sends to the other side's bluetooth equipment by antenna 13 after the asynchronous serial data line is received data.
Also link to each other between processor (MCU) 11 and the Bluetooth chip 12, be used for state communication between the two by the I/O mouth.
Referring to Fig. 1, processor (MCU) 11 links to each other with flash memory (Flash Memory) 10 by address wire, data line, and Bluetooth chip 12 links to each other with processor 11 by asynchronous serial data line, I/O mouth, and antenna 13 links to each other with Bluetooth chip 12 by radio frequency line.
Flash memory in said apparatus (Flash Memory) 10 is mainly finished the function of storage, and among the embodiment, this part can adopt the K9F1208 chip of Samsung to realize; Processor 11 is finished to the read-write of flash memory (FlashMemory) 10, control function and with Bluetooth chip 12 and is communicated by letter, and to the function that Bluetooth chip 12 is controlled, this part can adopt the MSP430F147IPM chip microcontroller of Texas Instruments; Bluetooth chip 12 is used for realizing the mutual conversion of baseband signal and radiofrequency signal between processor 11 and antenna 13, this part can adopt the BlueCore02-Flash chip of CSR company to realize; Antenna 13 is used to receive and dispatch radiofrequency signal, and this part can be selected AT 9520 products of Advanced Ceramic X company for use.
The utility model applies to the Bluetooth wireless transmission technology on the flash memory device, and carry out data transmission with equipment such as the mobile phone with Bluetooth function, computing machine, PDA, digital cameras, for equipment such as mobile phone, computing machine, PDA, digital camera provide wireless memory function.
