introduction The embedded monitoring system consisting of image acquisition and storage functions is an indispensable part of the security technology system. With the development of microelectronic technology and software technology, embedded technology has also made great progress. Therefore, the image data acquisition and storage monitoring system based on embedded technology is widely used in many occasions because of its intuitive, convenient and rich information content. The monitoring system works in a specific environment and has very special environmental and structural requirements, which puts high requirements on the hardware and software platform of the monitoring system. The performance of the processor is improved, the ability of the interface to transmit data is enhanced, especially in the future, the appearance of high-capacity memory, the miniaturization and multi-function of the image monitoring system are easy to implement. After the embedded technology is introduced into the image monitoring system, two problems need to be solved. The solution is a flexible image monitoring system structure adjustment, and the second is an interactive software design suitable for monitoring specifications, integrating image and signal detection and control. 1 System platform construction 1.1 Construction of the hardware platform ARM (AdvancedRISCMachines) can be considered as the name of a company, or as a general term for a type of microprocessor, and can also be considered as a technical name. The S3C2410 processor is a 32-bit microcontroller based on ARM's ARM920T processor core and 0.18um manufacturing process from Samsung. The processor has: independent 16KB instruction cache and 16KB data cache, MMU, TFT controller supporting TFT, NAND flash controller, 3 UART, 4 DMA, 4 TImer with PWM, I/O port, RTC , 8-channel 10-bit ADC, TouchScreen interface, IIC-BUS interface, IIS-BUS interface, 2 USB hosts, 1 USB device, SD host and MMC interface, 2 SPI. The S3C2410 processor can run at up to 203MHz. The hardware structure of the image acquisition system with S3C2410 as the core is shown in Figure 1. Because there is only a small amount of memory inside the S3C2410, I have to expand the memory of the system. As a 32-bit microprocessor, the S3C2410 supports 8-bit, 16-bit and 32-bit addressing modes, with 16M & TImes; 32-bit addressing capability. It is convenient to construct a large storage space, and the system memory is composed of FLASH and SDRAM. The digital camera is connected to the S3C2410 chip through the USB interface, and the S3C2410 chip is used to control the digital camera to collect images and store them in the memory. 1.2 Construction of the software platform Embedded Linux (EmbeddedLinux) refers to a dedicated Linux operating system that can be used in specific embedded applications after being miniaturized by Linux and can be solidified in a memory or a single-chip microcomputer. The specific construction process is shown in Figure 2.
