[Abstract]:GPRS wireless network has the advantages of wide coverage, high speed of data transmission, stable and reliable network, low cost and seamless connection with Internet. It can provide a good wireless data transmission channel for data acquisition and monitoring system. How to communicate through GPRS network and introduce GPRS network communication into actual data acquisition system has become a research direction with broad application prospect. High-precision AD conversion, mass data storage and portable technology is a hot spot in the field of data acquisition. The realization and application of these technologies can solve the problem of low precision in traditional data acquisition. Data is not easy to save and some other problems. Based on the research and analysis of wireless data principle and realization method, an embedded wireless data acquisition and control system based on single chip computer is designed in this paper. The system has the functions of accurate and fast data collection, large amount of stored information and wireless transmission of GPRS data. The system adopts modular design, mainly composed of U disk reading and writing module, data acquisition module, GPRS wireless data communication module and LCD liquid crystal display module. At the same time, the software design of the upper computer and the lower computer is completed. The structural design idea is adopted, the program is portable and the code optimization and reasonable operation efficiency is high. The system designed in this paper has the advantages of complete function, large amount of data acquisition, wireless communication, transmission and display function, clear system structure, high reliability, easy debugging, simple operation, reliable operation, friendly man-machine interface. High degree of automation and other advantages. The field test shows that the system has high data acquisition accuracy and accurate data transmission, and realizes the function of data acquisition well.
