The Design And Research Of Smart Home Security Monitoring System Based On ARM11

Usually,smart home security monitoring system is laid the bus in household, and install the system terminal is fixed.Through the bus terminal to communicate with other devices, and this way of installation has great limitations in household. This project, which aims at the branch of smart home security monitoring, presents a smart home security monitoring system. The system is equipped with mobile platform based on the smart car, which makes the design of the system has strong flexibility.This design a program that can track the path of memory, thus achieves the function of designated monitoring and timing patrol monitoring. This project includes:1. This design considers about the current condition of smart home, presents a smart home security monitoring system, it is equipped with smart car based on ARM11 and Linux operating system.Kinematics analysis has been done for the running of the mobile platform, provides a theoretical basis for the realization of control of the mobile platform.2. According to the design of the function, analyzed the principle of reflection type Opto-electronic testing velocity, transmission type Opto-electronic testing velocity and photoelectric coding speed.Analyzed the principle of the laser ranging, infrared distance measurement and ultrasonic ranging.Comparison the advantages and disadvantages of the fluxgate electric compass, magnetic resistance type electronic compass and hall electronic compass.Select the corresponding sensor constitute the mobile platform.And according to the design requirements, analysis and design of the circuit connection between the hardware modules and ARM11.3. To build the Linux system to the host machine and target machine. On the basis of ARM11 and Linux operating system, design of the driver of the hardware in the mobile platform such as Opto-electronic testing velocity, etc. This project designs a program to let the car run automatically. The program establishes avoidance memory by using ultrasonic obstacle and the use of electronic compass and photoelectric speed module, achieving functions of recording memory path and tracking.4. In order to achieve remote monitoring, the design illustrates the configuration and migration of the Boa server, the configuration and transplantation of the motion video server, as well as the configuration and transplantation of the ffmpeg multimedia video processing tools. By using Cron list in Linux, it achieves the function of system timing patro. In order to enhance the system’s ability to monitor, using photosensitive resistance design the scheme of the photoelectric effect automatic adjustment of the photosensitive USB camera lighting.5. Through the overall system testing, it shows that the function of the corresponding theoretical basis for the design, has been implemented.Finally, analyzed the existing system error and put forward the ways to overcome the error.Against disadvantages of mobile platform tracking for black line, this paper design a scheme about track operation that instead of tracking the black line,which make the operation of the mobile platform can completely get rid of the black line.It is the great innovations in this paper.The scheme using artificial obstacles of setting up the planning route,which make the design of security monitoring system can realize patrol monitoring function and has high adaptability and practicability.
