Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
As depicted in figs. 1 and 2, a kind of usb data transmitter based on Bluetooth technology, comprises CPU module 1, power module 2, display panel module 3, bluetooth module 4, USB common interface chip 5, USB female seat 6, USB interface 7 and SD draw-in groove 8.CPU module 1 adopts STM32F103VET6 chip, and power module 2 is lithium battery, and USB common interface chip 5 is CH375 chip, and display panel module 3 is TFT touch LCD screen.Display panel module 3, bluetooth module 4, USB interface 7 and SD draw-in groove 8 are all connected CPU module 1, USB female seat 6 and USB common interface chip 5 are equipped with two, each USB female seat 6 all connects CPU module by a USB common interface chip corresponding with it 5
The utility model can be applied in following three kinds of occasions, as shown in Figure 4:
1, in environment, do not have computing machine to need again to carry out under the condition of exchanges data, as Fig. 4 (a), when 1 pair of bluetooth module 4 of CPU module is controlled, the relative programs such as the setting of operation bluetooth, Bluetooth wireless transmission agreement, usb data read-write storage, realize local bluetooth to exchanges data is selected, asked to connect, connect, complete to search, the equipment of bluetooth equipment around.Idiographic flow is as shown in Figure 5: on interface, carry out bluetooth setting, if local bluetooth device is as slave part, Ying Rangqi can be found, wait for the request that establishes the link of other bluetooth equipments, click and accept, during interface display connects, wait setting up, be linked into after merit, to method, apparatus Transmit message transmission request, click and accept, receive the file that it sends over; If local bluetooth device is during as main equipment, carry out searching in effective range, find other bluetooth equipments, target device list is shown on liquid crystal display, selection will be set up after request, the equipment connecting, sends connection request, waits for and accepting, after method, apparatus is accepted, select target file, clicks and sends, and sends data; No matter, as main equipment or from machine equipment, complete after exchanges data, disconnect, return to interface.
