【摘要】：为实现计算机与智能手机之间的数据通信,提出了一种利用智能手机作为发送端、光学鼠标作为接收端的可见光通信链路。光学鼠标可以看成一个集成了图像处理单元的光学传感器,它可以感知到智能手机屏幕上的图像变化;这种变化最终反映成电脑光标值的变化,电脑充分感知这些数据信息,再通过特定的算法将发送数据解调出来;系统将数据调制成手机屏幕上的图片快速变化,接收方从光学鼠标输出的光标值中恢复发送端的数据。测试结果表明,在没有添加前向纠错的情况下,其通信速率可以达到2 bps。系统具有低成本和便携性的特点,非常适合在一些近场通信领域里应用,例如在无电磁链路(WiFi、蓝牙等)的情况下,PC从手机获取密码等小量数据文件,同时这种方式也确保了传输的安全性。
[Abstract]:In order to realize the data communication between the computer and the smart phone, a visible light communication link using the smart phone as the transmitter and the optical mouse as the receiver is proposed. An optical mouse can be viewed as an optical sensor integrated with an image processing unit, which can sense changes in images on a smartphone screen; this change is ultimately reflected in changes in the cursor value of a computer, which is fully aware of the data information. The system modulates the data into the pictures on the mobile phone screen quickly and the receiver recovers the data from the cursor output of the optical mouse. The test results show that the communication rate can reach 2 bps without adding forward error correction. The system has the characteristics of low cost and portability, so it is very suitable for application in some near field communication fields, for example, in the case of no electromagnetic link (WiFi, Bluetooth, etc.), the PC can obtain a small amount of data files such as password from the mobile phone. At the same time, this method also ensures the security of the transmission.
