Abstract

The invention discloses a device and method for carrying wireless data exchange between a computer and a smart phone terminal. The device comprises an NFC charging board which is used for receiving wireless data sent by the smart phone terminal with an NFC module; an RS232 interface which is used for connection with a computer terminal; a USB interface which is used for realizing communication between applications of the computer terminal and the smart phone terminal; a wireless sending module which is used for sending a read / write instruction to the smart phone terminal by the computer terminal; and a controller which is connected with the NFC charging board, the RS232 interface, the USB interface and the wireless sending module at the same time. According to the device and the method, through application of the structure and the method, the application range of a near filed communication technology is expanded; the device and the method are applicable to low data quantity transmission between the smart phones, and are also applicable to high data quantity wireless communication between the computers, and between the computer and the smart phone terminal; and the transmission efficiency of the wireless near filed communication technology is greatly improved through technical breakthrough of differential bidirectional read / write.

Description

technical field [0001] The invention relates to the field of electric power communication, in particular, to a device and method for wireless data exchange between a computer and a smart phone terminal. Background technique [0002] NFC near-field communication technology is evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technologies. It combines inductive card readers, inductive cards and point-to-point functions on a single chip, and can be compatible with Devices are identified and data exchanged. The operating frequency is 13.56MHz. NFC has the characteristics of low cost, easy to use and more intuitive, which makes it more potential in some fields. Through the combination of a chip, an antenna and some software, NFC can realize the communication of various devices within a few centimeters. The cost is low, and it is widely used in existing smart phones. At present, almost all smartphones on the market support NFC ...
