Design Of Internet Monitoring System Based On GPRS

The remote monitoring system based on the GPRS designed by this design through using intelligent network camera to communicate and image compression processing technology to providing an efficient,feasible and inexpensive solution for real-time monitoring systems with the mobile networks to transmit digital images.It can also better reflect the real-time conditions of the site and achieve unattended results.The purpose is to save the company's resources,people in the environment far away from the monitoring site can also clearly obtain the destination site situation,so that facilitating the monitoring staff to make real-time judgments to take measures.The purpose of this design is to achieve long-distance transmission of image data through the GPRS network,and to achieve the goal of transforming technology into productivity.The whole system is based on STM32F407ZET6 as the main control chip,and the operating system UCOSII is developed as a software platform.On the basis of the intelligent camera module OV7670 captures the image data,the SIMCOM company's SIM900 A module is used to transmit the collected image data to the GPRS network.On the server side,only one SIM card is required during the entire process to achieve longdistance data communication,and the collected data is displayed on the device in the form of pictures.This time,the main contents of the terminal device include: a detailed analysis of the STM32 internal chip and how the chip controls each peripheral module to achieve the purpose of long-distance communication;the use and configuration of the camera module;the working principle of the GPRS module and the AT commands about sending and receiving data,etc..This article mainly introduces the embedded operating system that needs to understand in the actual development process and the theoretical basis of the main control chip and some technical means and specific implementation process used in the manufacture of the chip and each module.At the same time,it also summarizes and looks forward to the development of this system to further improve the performance of this system.
