【摘要】：一般雷达站(比如用于观测天气的气象雷达)都建在偏僻的高山上,由于山路难行,雷达运行操作有固定的模式,技术人员需每隔一两个月上山检查雷达的运行情况,而平时只由当地村民代为看管。为了有效的实时监控设备的运行状况,本文拟设计并实现-套实时远程监控系统,不仅能实时的观察雷达运行的各项指标,也可以及时地记录出现故障时的真实数据,发送到远端的工程师终端。本文首先对Linux系统特点和ARM技术原理做了深入的研究之后,分析了远程监控系统(其核心是ARM处理器)的资源配置模块及其硬件实现,设计了一套集采集、监控、数据处理功能于一身的远程监控系统的硬件平台。其次,针对S3C2410硬件平台设计了软件平台,研究Linux内核裁减方法和U-boot程序调试方法,根据ARM硬件配置要求及嵌入式系统内核进行裁减配置设计,搭建了基于Linux的嵌入式系统平台。开发、适配基于Linux内核的网卡及18B20温度控制芯片的驱动,优化内核配置,研究OV511视频采集芯片驱动模块,使这些硬件模块能与内核有效通信。还有,开发了客户端程序,实现对远端数据的实时显示,最终集成整个软硬件平台,完成一套监控系统的整体设计与实现。针对应用场景的实际需求,实现了基于嵌入式平台的开关量、温度等简单的控制功能,并且可以将实时的温度信号采集到客户端。利用Visual Basic开发了应用客户端,主要实现了客户端和嵌入式系统平台的通信,完成视频、温度等信号的采集并实时显示。最后,对该系统的功能进行测试,并对各类故障给出了有效的解决办法。
[Abstract]:General radar stations (such as weather radar used to observe the weather) are built on remote mountains. Because mountain roads are difficult, radar operations are in a fixed mode, and technicians have to go up the mountain every one or two months to check the operation of the radar. And usually only by the local villagers on behalf of the guard. In order to effectively monitor the running condition of the equipment, this paper designs and implements a set of real-time remote monitoring system, which can not only observe the targets of radar operation in real time, but also record the real data of failure in time. Send to remote engineer terminal. After deeply studying the characteristics of Linux system and the principle of ARM technology, this paper analyzes the resource configuration module and its hardware implementation of remote monitoring system (the core of which is ARM processor), and designs a set of collection and monitoring. Data processing function in a remote monitoring system hardware platform. Secondly, the software platform is designed for the S3C2410 hardware platform. The Linux kernel reduction method and the U-boot program debugging method are studied. According to the requirements of ARM hardware configuration and the embedded system kernel, the reduction configuration design is carried out. The embedded system platform based on Linux is built. This paper develops and adapts the driver of network card and 18B20 temperature control chip based on Linux kernel, optimizes the configuration of the kernel, studies the driver module of OV511 video capture chip, and makes these hardware modules communicate effectively with the kernel. In addition, the client program is developed to display the remote data in real time. Finally, the whole software and hardware platform is integrated to complete the whole design and implementation of a monitoring system. According to the actual requirement of the application scene, the simple control functions such as switch quantity and temperature based on embedded platform are realized, and the real-time temperature signal can be collected to the client. The application client is developed by using Visual Basic. The communication between the client and the embedded system platform is realized, and the video and temperature signals are collected and displayed in real time. Finally, the function of the system is tested and effective solutions are given.
