Description
Technical field
The utility model relates to a kind of bluetooth bridge of realizing long-range data communication, belongs to data transmission device, is particularly useful for more than 30m length apart from blue-teeth data communication.
Background technology
Existing data transfer mode is divided into wire transmission and wireless transmission, and conventional data transmission adopts ray mode, therefore needs wiring in addition, has increased cost, brings inconvenience to using simultaneously, high to installation site and required distance, has limited the development of a lot of application.
Wireless communication technique has solved the predicament of wire transmission to a certain extent.
Wireless data communication technical development is swift and violent, and technology kind is varied, but the technology of existing main (stream) has RFID(radio frequency card), ZigBee, wireless data serial communication and basket tooth mechanics of communication.
RFID technology is pairing, connecting link not, and in the many occasions of number of devices, communication is unreliable, and speed is low; Its communication distance is also extremely limited, increases journey with high costs.
ZigBee mechanics of communication is advanced, and networking linking automation degree is high, and communication speed is high, connects reliable.But P2P(is point-to-point) application is very not convenient, total system cost is higher.
Wireless data technology of serial communication device category is numerous and diverse, easy to use, and cost differs greatly.But have linking automation degree low, intrinsic confidentiality is poor, the shortcoming that speed is not high.
Bluetooth technology networking linking automation degree is high, communication speed is high, connection is reliable, P2P(is point-to-point) application convenience, intrinsic good confidentiality, total system cost be lower.But V1.0 is limited to V3.0 communication distance.Bluetooth technology has solved the predicament of wire transmission to a certain extent, but the distance of most of Bluetooth transmission is limited, common Bluetooth transmission generally can only be within the scope of 10 meters, surpass the very serious of this range signal decay, wireless connections are unstable, so study a kind of technology that can expand Bluetooth transmission distance, become the task of top priority.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of compatibility good, simple in structure, install and use the bluetooth bridge of realizing long-range data communication convenient, reliability is high.
The utility model solves the technical scheme that its technical problem adopts:
The utility model comprises bluetooth V4.0 module and bluetooth V2.0 module; The reset terminal of described bluetooth V4.0 module and AT Enable Pin be corresponding digital output port D0 and the digital output port D1 that connects bluetooth V2.0 module respectively, the TXD of the COM port of described bluetooth V4.0 module and RXD end intersects respectively RXD and the TXD end of the COM port that connects bluetooth V2.0 module, and the antenna end of described bluetooth V4.0 module and bluetooth V2.0 module connects respectively transmitting antenna.
The power end of described bluetooth V4.0 module and bluetooth V2.0 module connects standard USB power supply altogether.
The good effect that the utility model produces is as follows: (1) the utility model adopts bluetooth V4.0 module, has guaranteed the long distance of transfer of data, and absolute distance can reach more than 30 meters; Adopt bluetooth V2.0 module, realize backward compatible maximization; (2) the utility model can complete pattern conversion, select different headend equipments match connections as required, automatic realization (P2P) digital communication one to one, and simple in structure, reliability is high, and volume is little to be easy to carry.
