摘要
设计主要采用的是以ARM7TDMI为核心的嵌入式微处理器S3C44B0X,在S3C44B0X处理器外部配以以太网控制器CS8900A、温度传感器LM35和存储芯片等实现远程温度监控系统的硬件平台;同时,采用μCLinux操作系统为软件平台。在μCLinux操作系统下,对Boa Web服务器进行配置和移植,然后编写相应的动态Web页面的CGI程序,就可以在远端主机实时访问远端温度传感器所测量的当前温度。当温度超过设定值时,进行报警,从而达到远程监控的目的。
This design mainly uses an embedded microprocessor S3C44BOX based on ARM7TDMI core, and the exterior of the S3C44BOX processor appended Ethernet Controller Chip CS8900A, temperature sensor LM35, and memory chip, to realize hardware platform of long-distance temperature monitor and control system. At the same time, it uses μCLinux operating system as software platform. Under the μCLinux operating system, by configuring and transplanting the Boa Web Server, then editing corresponding CGI program of dynamic webpage, we can access present temperature measured by distant temperature sensor from time to time. When the temperature value is beyond the limitation, the system will give an alarm signal. Finally, the design realizes the purpose of long-distance monitor and control.
