ARM-based Intelligent Control Alarm System Design And Implementation

The subject of the design and implementation of intelligent monitoring system based on ARM9 embedded Linux and experimental platform to achieve the function of the video image capture, processing and moving image capture devices for video alarm and remote monitoring. System hardware platform is UP-NetARM2410-S test platform that supports Plug and Play USB camera that can capture video images. In addition the GSM system, the camera module can be used in conjunction with the USB video device switches to realize the remote control, abnormal situation to the police. The LCD module on the platform mainly to achieve the alarm information display problems.From the function of this system is mainly divided into the image capture and monitor the user control commands two functional modules. Image Capture module is mainly responsible for the collection of video image information, which is mainly achieved through the Video4Linux (V4L). As a Linux kernel on the video device driver, V4L video device to provide a range of application programming interface functions to achieve the use of ordinary video camera, the information collection.Another use of the collected image information such as median filtering method for processing image processing technology, an improved three-frame difference method to analyze the information on the frame, and whether there are moving objects using a "double three" test method.Finally, realization of the function of the system were tested. The results show that use of SMS on mobile phones to send commands to the video equipment video equipment to achieve the remote control switch for the video image captured the existence of moving objects can make the right judgments, and the implementation of the alarm information display.
