GPRS Based Guard Robot Alarm System Design

This paper presents a practical approach to design guard robot alarm system using GPRS technology. GPRS offers an interesting communications infrastructure for remotely accessing, controlling and interacting with robots in an integrated and highly portable manner, particularly in recent years the GPRS network provides wireless access of internet for mobile phone which becomes the most important and common terminal equipment. Therefore, in this paper the alarm information is designed to send to the user´s mobile phone, and add man-made intervention to the system, thus achieves a more convenient and reliable alarm system. The system mainly consists of two parts: detection of abnormal and dangerous situation in domestic environment and sending the alarm information as MMS form to the user´s phone via GPRS networks. Finally experiments show that the alarm system can accurately send alarm information to the user´s mobile phone. The system is low-cost, flexible, reliable, and can be widely used.
