The Design Of Environmental Parameters Monitoring System Based On GPRS

With the progress of technology and the development of the society, peoplepay more and more attention to their own life environment. And exactmeasurement to environmental parameters is necessary for industrial productionsites and agricultural shelters work orderly and smoothly. In view of thissituation, research reliable and practical environment parameters monitoringsystem are particularly important.Along with the rapid development of wireless communication networktechnology especially the GPRS technology, microcomputer and sensortechnology, advanced technology is used in all kinds of environmentalparameters monitor areas, causing the system function richer, the more stableperformance has become possible. The system selects temperature, humidity,carbon dioxide and light intensity this4parameters to design a kind of based onGPRS environment monitoring system parameters.The system hardware section which is also called the data acquisitionterminal comprises three parts: the sensor module circuit, micro controller circuitand GPRS wireless communication module. With the core of ARM7-LPC2103,the control sensor module circuit collects data and use AD for module conversion,at the same time through a serial port and GPRS wireless module MC55communication, and use AT command sent data collected through the GPRSnetworks, to the Internet network. In software, The system uses a graphicaldevelopment software LabVIEW to design the data monitoring center. LabVIEWreceives data from the Internet network through the TCP.It designs a simpleinterface to display data, establishing the connection database, realizing tostorage and query the historical data.The system is mainly for greenhouse environment, animal breeding environment and other indoor environment, using APN dedicated networkconnection mode to realize the design of environmental parameters monitorsystem which is based on GPRS wireless communication technology. The systemhas a better applicable value with expansibility. The system can use the differentGPRS network access just by change the software without the hardware. With thetest, the system is stable, and the precision of data is on the acquisition range.The subject is more importance for the environmental parameters monitor system.
