【摘要】：近年来,随着嵌入式技术优点的不断释放,嵌入式系统在社会各大领域得到了广泛的运用并有着较高的关注度。嵌入式仓库监控系统就是其中较为热门的应用点之一。仓库作为存储民生物资的地点,在生产环节中有着较为重要的地位。为了保证物资的安全以及存储环境的要求,这就需要对仓库进行视频监控以及温湿度采集。传统的监控系统一般都是将视频监控系统和温湿度采集系统进行分离,分别进行实现。随着相关技术的发展,前端一体化、报警智能化以及报警联动性等特点将会大面积普及,以往的模式将存在着一定的局限性。本文以嵌入式技术、视频技术和网络技术为基础,设计并实现了一款基于嵌入式Linux的仓库监控系统。其前端以嵌入式S3C2440为控制核心、STC89c51单片机作为采集模块处理器进行搭建,在对硬件和软件进行了总体设计之后,重点研究并实现了TCP/IP协议网络下的嵌入式前端TCP方式的温湿度及控制信号传输和UDP方式的视频传输；实现了基于Video4Linux(V4L)技术对视频图像信息的采集；最后在QT Creator下对界面进行了设计以及完成了相互之间信号与槽的关联。该嵌入式仓库监控系统采用ARM+51单片机的设计方案,使得系统前端集成度较高、可靠性好、功耗低、成本低廉,有着一定的经济实用性。
[Abstract]:In recent years, with the continuous release of the advantages of embedded technology, embedded system has been widely used in various fields of society and has a high degree of concern. Embedded warehouse monitoring system is one of the most popular applications. Warehouse, as a place where people's livelihood goods are stored, plays an important role in production. In order to ensure the security of materials and the requirements of storage environment, it is necessary to carry out video surveillance and temperature and humidity acquisition. The traditional monitoring system usually separates the video surveillance system from the temperature and humidity acquisition system and implements them separately. With the development of related technology, the features of front end integration, alarm intelligence and alarm linkage will be popularized in a large area, and the previous models will have some limitations. Based on embedded technology, video technology and network technology, a warehouse monitoring system based on embedded Linux is designed and implemented in this paper. The front-end is built with embedded S3C2440 as the control core, and the STC89c51 microcontroller is used as the processor of the acquisition module. After the overall design of the hardware and software, The temperature and humidity of the embedded front-end TCP and the transmission of the control signal and the video transmission of the UDP mode are studied and realized in the TCP/IP protocol network. The acquisition of video image information based on Video4Linux (V4L) technology is realized. Finally, the interface is designed under QT Creator and the correlation between signals and slots is completed. The embedded warehouse monitoring system adopts the design scheme of ARM 51 single chip microcomputer, which makes the front end of the system have high integration, good reliability, low power consumption, low cost, and has certain economic practicability.
