Abstract
The utility model relates to an adapter for a blue tooth USB interface, which comprises a USB interface. The utility model is characterized in that the utility model also comprises a microstrip antenna, a blue tooth module and a voltage converting circuit, wherein a radio frequency signal input end of the blue tooth module is connected to the microstrip antenna; a 5 V power end of the USB interface is connected to an input end of the voltage converting circuit; a 3.3 V voltage output end of the voltage converting circuit is connected to a power input end of the blue tooth module; a data end of the USB interface is connected to a data end of the blue tooth module by a signal matching circuit. Based on the code requirement of a blue tooth, the utility model adopts a time division multiple access technique to support async data, and an external blue tooth with a standard USB interface is used to support a basic communication protocol album. The utility model can be widely used in the fields of industry, agriculture, medicine, scientific research, military affairs, etc. More specifically, users just need to provide interfaces, such as standard USB general parallel interfaces, etc., the utility model and drivers are externally connected, and then the blue tooth of products can be realized.
Description
Technical field
The utility model relates to the utilization of bluetooth short-distance wireless mechanics of communication.Specifically be a kind of based on the equipment with usb interface Bluetooth wireless transmission agreement and design of usb1.1 standard and realization, that can expand Bluetooth function, support plug and play fast.
Technical background
Bluetooth technology is a kind of short-distance wireless communication technology, and its working frequency range is 2.4GHz.Because of its good anti-interference and autgmentability, Bluetooth technology can be widely used in industry, agricultural and civilian consumer product area.The bluetooth international norm has been formulated in November, 1998 and has been passed through, and through the practice in 2 years, technology was comparatively stable ripe.Current, be a focus based on the application study of bluetooth, all in exploration, technical merit is close both at home and abroad.
Although the USB interface utilization more and more widely, become a kind of comparatively common interface, but do not see at present to have and to expand Bluetooth function fast, support the bluetooth USB interface of plug and play scheme, just may will have the device extension Bluetooth function of USB interface easily if design the adapter of the usb of bluetooth, make it realize Bluetooth wireless transmission easily!
Summary of the invention
The purpose of this utility model is: provide a kind of based on the design of Bluetooth wireless transmission agreement and usb1.1 standard and have the usb interface, can expand Bluetooth function fast, support the bluetooth usb adapter of plug and play scheme.
The technical solution adopted in the utility model is such, and promptly a kind of bluetooth USB adapter comprises USB interface, it is characterized in that: adapter also comprises microstrip antenna, bluetooth module and voltage conversion circuit; Wherein, the radio-frequency (RF) signal input end of bluetooth module is connected with microstrip antenna, the 5V power end of USB interface and the input of voltage conversion circuit, the 3.3V voltage output end of voltage conversion circuit is connected with the power input of bluetooth module, and the data terminal of USB interface connects the data terminal of bluetooth module by the Signal Matching circuit.
The utility model adopts tdma based on module and Bluetooth specification requirement, supports asynchronous data; Support the basic communication protocol suite, extend out bluetooth, can be widely used in industry, agricultural, medical science and fields such as scientific research and military affairs with standard usb interface.Specifically, the user only need provide the interfaces such as the general parallel port of USB of standard, connect the utility model and driver outward after, can realize the bluetoothization of product.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of the utility model microstrip antenna.
In the accompanying drawing: J1 is the USB joint of standard, and voltage conversion circuit chip (U1) model is 7301, by it 5V power source conversion is become 3.3V, and the model of bluetooth module (U2) is the ROK101 00 of Ericsson.R1, R2, R3 are resistance in an embodiment, and A1 is a microstrip antenna.
Embodiment
1 pin of USB joint (J1) is that Vcc holds (Vin) for the voltage income that the 5V power supply inputs to voltage conversion circuit chip (U1), and the voltage conversion circuit chip is powered to bluetooth module from voltage output end (Vout) output 3.3V.The D+ of USB joint (J1) is the data anode, D-is the data negative terminal, give D+, the D-end of bluetooth module (U2) behind the Signal Matching circuit of their signal via resistance R 1, R2, R3 formation, in bluetooth module (U2), change into Bluetooth signal and give microstrip antenna (A1), send to the space by it.Microstrip antenna (A1) is a L shaped antenna that is arranged on the pcb board.Make this small product size littler, weight is lighter, is easy to carry.
