Abstract


In recent years, as the domestic and international research hotspot, Internet of things technology gets great attention. In the field of Internet of things ,China has started a large number of theoretical and applied research, and has made great progress. As the content of network applications, remote monitoring technology is facing new opportunities and challenges.This thesis presents a new wireless remote monitoring system based on GPRS. This system adopts“monitoring node and monitoring center”structure. The monitoring node integrates D203S pyroelectric infrared sensor, SHT10 temperature and humidity sensor, TSL2561 illuminance sensor and GXT-Y601 image sensor. According to the performance requirements , this system uses the architecture of Atmega128 + TR800 based on sensor technology with Atmega128 MCU as the main controller and TR800 as the wireless transmission module. Environmental data uses the data packet forwarding solution, in accordance with the Xmodem protocol format uploading the data to TR800 wireless module and using the AT command via MMS to send to the mobile phone terminal. It can efficiently detect the intrusion, collect the data and process the alarm with the advantages of low investment, good reliability.This thesis discusses the main modules of the hardware and software design in detail, focusing on each module hardware circuit design and implementation, the system function module detailed description and software realization process. In a laboratory environment, We build the hardware platform and use VC++6.0 to prepare the platform test software. What’s more ,We have made the exhaustive test and analysis of the system response time, real-time, reliability ,which proves the feasibility and validity of this system. This scheme has certain reference significance to the further study of the intelligent mobile phone monitoring system.
