Design of a Wireless Monitoring System Based on GSM/GPRS

The design of a wireless monitoring system composed of embedded monitoring terminals,users' cell phones and a remote computer as the monitoring center is introduced.The method of application of a wireless module in embedded systems is emphatically discussed.The method of monitoring equipments in the field by using the wireless module to transmit and receive short messages is introduced;the process of establishing a link between the wireless module in the GPRS network and the fixed IP computer in the Internet and communicating each other are analyzed.The result shows that,in the area where the GSM/GPRS network is available,the system can accomplish the data acquisition on line,wireless remote data transmit and monitoring for the equipments in the field.The solution of embedded wireless remote monitoring has a prominent advantage when constructing monitoring systems in the open air,field place,mobile operation condition or wherever the network cables can not reach.
