矿井下的温湿度、气体浓度和压力是作业安全的3个重要因素。为了有效实时地监控这3个因素,提出了一种基于ARM-Linux嵌入式远程监控系统,介绍了系统设计的原理和实现方法。主要阐述了以S3C2440A为主控芯片,并且移植了具有实时性的嵌入式操作系统Linux,设计相应的硬件驱动和应用程序。重点分析了TCP协议、嵌入式Web服务器和JPEG压缩编码技术。
Mine temperature and humidity, gas concentration and pressure are three important factors for job safety. In order to effectively monitor these three factors in real time, an embedded remote monitoring system based on ARM-Linux is proposed, and the principle and implementation of the system design are introduced. Mainly elaborated to S3C2440A as the main control chip, and transplant real-time embedded operating system Linux, design the appropriate hardware drivers and applications. Focus on the TCP protocol, embedded Web server and JPEG compression coding technology.
