Remote Data Acquisition System Based On C8051F020

With the development of wireless technology, the application of wireless communication technology in industry domain become more and more common, it become more and more important role in industry. GSM system is the most developed mobile communication system in China now, using GSM network for the transmission of data has lots of advantages.This article describes a kind of C8051F020 MCU and Siemens TC35i module as the core of remote multi-channel analog data acquisition system. The system can complete eight-way analog signal data acquisition, A / D conversion, and is capable of data collected by TC35i module to transmit short messages in the form of PC, on-site to achieve some control, to achieve remote monitoring, for industrial measurement and monitoring of production and other occasions. Described in detail the system's architecture, hardware configuration, interface and software design, analyzed the problems in debugging.This system is especially suitable for small flow of data collection and frequent delivery,as a basis,can develop a variety of extremely optimistic about the prospects for various applications,such as plant control,remote maintenance systems and information inquiry system. Believe that with the development of network technology, will facilitate data collection in many industries has been widely used.
