Abstract
The utility model discloses Bluetooth-based file transmission equipment which comprises a single-chip microcomputer, a Bluetooth module, an SD card reading and writing module and an LCD screen, wherein the single-chip microcomputer controls the equipment, the Bluetooth module communicates with other equipment, the SD card reading and writing module reads and writes an SD card, and the LCD screen displays the state of the equipment. The Bluetooth-based file transmission equipment enables wireless transmission of files in the SD card, and electronic equipment as a computer or mobile phone can be directly connected with the SD card to upload files into the SD card or download files from the SD card.
Description
Technical field
The utility model relates to field of data transmission, relates in particular to a kind of document transmission device based on bluetooth.
Background technology
At present on electronic market, universal several files comprise two kinds of wire transmission and wireless transmission.Wire transmission is divided into these several class of electronic devices such as USB flash disk, SD card, hard disk substantially, wherein SD card is a kind of memory device of new generation of based semiconductor fast-flash memory device, have be small and exquisitely easy to carry, the advantage such as memory capacity is large, low price, dependable performance, be widely used in store file data on mancarried device, such as mobile phone, digital camera, personal digital assistant (PDA) and multimedia player etc.And conventional wireless transmission method mainly comprises WIFI and Bluetooth technology, wherein, bluetooth is a kind of radiotelegraphy of support equipment short haul connection, can, comprising mobile phone, PDA, wireless headset, notebook computer, being correlated with and carrying out wireless messages exchange between numerous equipment such as peripheral hardware, there is the benefits such as near radio connection cheaply.
Current SD card depends on wired one-way transmission, need to be under the help of card reader, the equipment by computer etc. with usb terminal interface is given file transfer other equipment that do not possess read-write SD card ability, the transmission of file can not be realized easily with mobile devices such as mobile phones, contacting directly of other device files such as SD card and mobile phone, panel computer cannot be realized.
Summary of the invention
In order to address the above problem, the utility model provides a kind of document transmission device based on bluetooth.
Based on a document transmission device for bluetooth, comprising:
Single-chip microcomputer, for controlling described equipment;
Bluetooth module, for communicating with other equipment;
SD card module for reading and writing, for carrying out read-write operation to SD card;
LCDs, for the state of display device.
As preferably, between SD card and single-chip microcomputer, communicate by the SPI interface of SD card module for reading and writing.
As preferably, described single-chip microcomputer comprises ARM hardware system.
As preferably, the read write command of FAT file system is write in the instruction providing by ARM hardware system, and by the file in described read write command read-write SD card.
As preferably, bluetooth module by the data transmission reading from SD card to other equipment.
As preferably, described LCDs is embedded on described equipment, for the transmission situation of display file.
As preferably, described equipment also comprises independent current source, for giving described equipment power supply.
As preferably, described single-chip microcomputer is STM32F103 single-chip microcomputer.
The beneficial effects of the utility model are: can realize the wireless transmission of file in SD card, realize contacting directly and file wherein being uploaded to the function of download of other electronic equipments such as computer, mobile phone and SD card.
