The application of wireless communications in the smartcar control system
Abstract
Short-distance wireless communication have a wide range, in general sense, as long as both send and receive communications by radio waves to transmit information, and transmission distance is limited in a shorter range, usually less than tens of meters, can be called short-range wireless communications . The 2.4 GHz frequency band is global opening band for the ISM (industrial, scientific and medical) , the user need not apply for permits. To users ,this has brought great convenience.
This article does a detailed study on the application of wireless communications in the smart car control system, described in detail the design and debugging for the system of real-time monitoring and control for the smartcar¡¯s parameters which use nRF24E1 rapid development.
First of all, described the short-distance wireless communication¡¯s features, development and mainstream technology, and a detailed introduction of the nRF24E1 rapid development system used in this system . Then, given the methods and steps for Visual Basic code and provide a number of debugging and configuration methods against some of the key steps and difficulty, and the author ¡¯s lessons in design and debugging. And finally, provide reference code of control by wireless .
Keywords: Smartcar; short-distance wireless communication; nRF24E1;
