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 .
