[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.
