Abstract


With the rapid development of data acquisition and embedded systems , as well as the modern field of industrial measurement and control , data acquisition increasingly high demand , this paper proposes to combine these two techniques to achieve miniaturization , high-capacity , high real-time high stability and friendly interactive interface data acquisition system . In this paper, the background for the automatic detection of the institutions of higher learning experiment teaching system , select a the embedded platform data acquisition system design , as auxiliary equipment in the experimental teaching . This paper first introduces embedded systems , embedded processor and operating system related knowledge , and then introduced a data acquisition technology . Determine the temperature , weight , speed , light , infrared , gas concentration , and distance signal to the automatic detection experiments ARM processor and embedded operating system WinCE - based data acquisition system designed for the collection of objects . The system hardware platform using a the Samsung S3C2440A microprocessor , the hardware platform also has a rich interface for easy expansion and development : Camera interface , LCD interface , USB interface and touch screen interface . Hardware based on the software side introduced the Windows CE operating system features and architecture , as well as WinCE build and configuration process . Then write ADC stream interface driver using Platform Builder platform , GPIO drive added to the Windows CE image , provide the conditions for the experimental data acquisition . According to the experimental content to write applications using Visual Studio 2005 Tools driver function interface to read data , and data acquisition functions . The development process , the use of cross-compiler , tested on the ADC driver as well as the acquisition software , real-time acquisition and processing of the experimental variables .
