Embodiment Construction

[0112] The principles and features of the present invention will be described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0113] figure 1 It is a schematic structural diagram of the fast access short-distance wireless communication system for controlling the communication range in the present invention. The system includes a master module 1 and a slave module 2; wherein, the master module 1 is used to send a first distance reference signal containing master module information and communication distance information; the slave module 2 judges the master module 1 according to the received first distance reference signal Whether the distance with the slave module 2 meets the preset range, if so, the master module 1 and the slave module 2 quickly establish a wireless communication connection and perform data exchange according to the pr...

Abstract

The invention relates to a system and a method for fast accessing high-efficiency near field communication with a controllable communication range. The system comprises at least one master module and at least one slave module, wherein the master module is used for sending a distance reference signal which includes master module information and communication distance information; the slave module is used for judging whether the distance between the master module and the slave module is in accordance with a preset range according to the received distance reference signal; and if the distance between the master module and the slave module is in accordance with the preset range, wireless communication connection between the master module and the slave module is established according to a preset protocol, and data exchange between the master module and the slave module is realized. A reference unit and a measuring unit communicate with each other by adopting a low-frequency magnetic signal or an ultrasonic wave signal, so a requirement for near access can be met. By the system and the method, instant, fast and high-efficiency wireless data exchange within a specific distance range is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to a system and method for fast access to efficient short-distance wireless communication with controllable communication range. Background technique [0002] At present, high-speed wireless transmission has been widely used for data exchange on computers or mobile devices. Wi-Fi (IEEE802.11a / b / g / n standard), Bluetooth, Zigbee (IEEE 802.15.4 standard), and UWB (Ultra Wideband, ultra-wideband wireless transmission) and other technologies. These high-speed wireless communications enable information exchange and function sharing between computers or mobile devices. Users can implement streaming media file transmission, address book exchange, and shared access to the Internet in these mobile devices. These technologies are all aimed at long-term, multiple users, and long-distance (more than 10 meters) data exchange applications; when using this technology, users need to perform more c...
