Abstract
The contemporary era, rapid development of mobile communications, GPRS (General Packet Radio Service) for the majority of people are familiar with. GPRS is the existing GSM system developed a new bearing business, aims to provide GSM users in the form of packet data services. Remote monitoring system is important in many places, such as electricity, telecommunications, banking, transport, shopping malls and other businesses need extensive exchange of information production and management systems required. Remote Monitoring System traditional way to achieve the general need to build and maintain their own wired or wireless network, high maintenance costs, limited communication distance. With the development of communication technology, the original remote monitoring system has become increasingly unable to meet various requirements, we need real-time higher and farther the distance, lower-cost means of communication, the paper put forward a GPRS-based Long-distance data transmission system, to focus on monitoring system for the application object. The system from Samsung as the ARM microprocessor chip S3C44BOX, ARM software uC / OS operating system, Q2406 as a GPRS module, ARM chip and between GPRS module with a serial port communications.
