【摘要】：罐车由于其运输成本低廉、机动灵活的特点，成为了中短途危化品运输的主要工具。但是由于其移动分散的特性，如何做好危化品运输过程中罐车的实时监控已经成为各个危化品运输公司的一个共同难题。本文利用嵌入式的相关技术，设计了一套基于嵌入式Linux的罐车监控终端，实现了罐车运输过程视频、传感器信息的实时采集，远程Web实时监控，测试运行结果稳定，具有一定的实用价值。在设计研究过程中主要进行了以下几方面的工作： (1)对罐车监控的整体需求进行了分析，提出了基于嵌入式Linux的无线监控方案，并对嵌入式Web技术，wifi无线网络技术、TCP/IP协议等进行了学习和研究。 (2)学习了嵌入式硬件相关知识，实验和验证相关模块，选定上位机采用以S3C2440A为主控芯片的mini2440开发板，选用STC12C5A60S2单片机作为下位机主控芯片，上位机外接了USB摄像头、USB无线网卡、优盘等外设，，下位机外接出入口阀门监测传感器、温度传感器等模块，完成了系统硬件平台搭建； (3)通过对引导程序Uboot、嵌入式Linux操作系统和相关驱动以及Linux的根文件系统进行了学习和研究，根据硬件平台要求，完成了系统底层软件的裁剪和移植； (4)根据功能需求，设计了满足监控需求的4个应用层软件模块：视频模块、传感器信息采集模块、嵌入式Web服务器模块、邮件报警模块。 (5)搭建无线网络测试环境，对整个系统进行了测试。
[Abstract]:Because of its low transportation cost and flexible characteristics, tank truck has become the main tool for short and medium distance transportation of dangerous chemicals. However, due to its dispersive characteristics, how to do a good job in the transport of dangerous chemicals tankers in the process of real-time monitoring has become a common problem of dangerous chemical transport companies. In this paper, we design a monitoring terminal of tank car based on embedded Linux, which realizes the real-time collection of sensor information, remote Web monitoring, and stable test results. It has certain practical value. In the process of design and research, the main work is as follows: (1) the overall demand of tank car monitoring is analyzed, and a wireless monitoring scheme based on embedded Linux is proposed. The embedded Web technology and wifi wireless network technology, such as TCP / IP protocol, are studied and studied. (2) the embedded hardware related knowledge, experiment and verification module are studied, and the host computer is selected to adopt mini2440 development board with S3C2440A as the main control chip. The STC12C5A60S2 microcontroller is selected as the main control chip of the lower computer, the host computer is connected with the USB camera and USB wireless network card, USB wireless card and other peripheral devices, the lower computer is connected with the modules of the inlet and outlet valve monitoring sensor, the temperature sensor and so on, and the hardware platform of the system is built. (3) through the study and research on the boot program Uboot, embedded Linux operating system and related drivers as well as the root file system of Linux, according to the requirement of hardware platform, the bottom software of the system is cut and transplanted. (4) according to the function requirement, four application layer software modules are designed: video module, sensor information collection module, embedded Web server module. E-mail alarm module. (5) build wireless network test environment and test the whole system.
