Design Of An Intelligent Home Monitoring System Based On ARM And GPRS

In recent years,with the rapid development of embedded technology,network technology and multimedia technology,video surveillance system is widely applied in all kinds of security domain.Designing a low cost,high image quality,alarm flexible monitoring system is very necessary,because people put forward high cost performance,high-definition,flexible alarm linkage requirements for family monitoring system.This paper analyzes the application status and future development trend of embedded network video surveillance in home security both here and abroad,and deeply researches the embedded Linux system,network video monitoring and alarm linkage,and designs and realizes the application of the embedded system Home care system.The system includes the design of hardware module,the development of network video acquisition and transmission,display and alarm etc.The design verified the function of the family monitoring system.The main work of this paper and the results are as follows:1.According to the analysis of the current mainstream embedded systems,combination with video monitoring in the family on the basis of user requirements,the S5PV210 ARM chip is chosen as the main control chip of the monitoring system,and the design scheme of intelligent home monitoring system based on ARM and GPRS is proposed.2.The design and development of the device driver for each module in the monitoring system are designed and developed.Based on the characteristics of the embedded monitoring system and hardware features,installing the cross compiling environment,making the root file system,and the system bootstrap and system kernel are configured and transplanted.The design completed the design and development of video module,network module,alarm linkage module,memory module and other module design and development.3.Based on the drive of system equipment,the application program of user's requirement is developed.Realized the video data acquisition and transmission and display,and it can set different kinds of risk signal corresponding to the alarm mode and the model of evidence collection.4.Taking into account the system information security requirements,the system is designed to verify the landing,while the corresponding service to obtain the re-verification model,and fully protect the family safety.5.The following functions of the system are tested and verified: real-time video viewing of the remote control and local client to the dispatched scene;the abnormal scenes are manually captured and saved by the browser on the client;the sensor on the monitoring system terminal has temperature sensor,Human infrared sensor and infrared receiver,these sensors are aimed to monitor the environment,when the danger signal is monitored,it will start the remote warning of short messages,local buzzer warning;for the human body infrared sensor to monitor the intruder,will start the OV9650 camera to shoot the scene to grasp the evidence.6.At last,the research system is summarized,and some suggestions are put forward for further improvement and future design.
