Research of real-time image acquisition system based on ARM 7 for agricultural environmental monitoring

The internet of things (IOT) has brought a broader space to the intensive development of modern agriculture in the application of agricultural environmental monitoring. To solve the problems of real-time video acquisition, image acquisition and motion capture in the agricultural environment, this paper use the ARM S3C44B0X as the processor and put forward a new kind of real-time video acquisition technique based on 32bits embedded processor system. the optimized and minimized hardware system is designed, including designs the GAL gathering controller to control the output digital video signal data form SAA7111A to the frame buffer storage memory Al422, and expanded the interface of FLASH, SDRAM, CF Card, RS232, JTAG and so on; Secondly, through the transplanting of U-boot and uClinux system, the improved moving object examination algorithm using the difference of background was proposed based on the software platform constructed. Finally, the debug process of the unit circuit of the whole system is introduced in proper sequence. As a result, the digital image collecting system based on ARM S3C44B0X exists as a sole unit, and has lots of advantages such as small volume, low cost, good expansion, multifunctional and low power consumption. The system realized the functions of real-time video acquisition and processing. Combined with the GPS module and other sensors, the system can be widely used in the aspects of agricultural environmental monitoring, real-time data acquisition and remote monitoring and so on, with a more broad application prospects.
