【摘要】 目前高校教学楼教室的管理的信息化、自动化程度较低,资源利用不充分。本文设计了基于CAN总线(控制局域网)和嵌入式Internet的教室资源管理系统,以达到高校教室资源合理使用,以及方便使用者随时的了解自己正在使用的教室的教学安排,并达到减少电能消耗的目的。本文应用先进的嵌入式系统技术、网络技术、和现场总线技术以及计算机软件,设计了一套基于CAN总线和嵌入式Internet的教室资源管理系统。整个系统包含三个部分,即：教室终端控制板、Internet与CAN总线之间的嵌入式协议转换器、配套的计算机软件。其中,教室终端控制板安装在每个教室里。系统包括了两级网络,教室终端控制板与协议转换器之间使用CAN总线组网。而计算机软件平台与协议转换器之间则通过Internet远程通信。而协议转换器可以通过以太网、无线局域网和GPRS等多种有线或无线的方式接入Internet,使得布线更加灵活方便。本系统有三个主要作用：(1)实现对教室的光照、温度等信息进行采集,以供查询；(2)根据设置要求、当前的时间和采集到的信息,自动的对教室的照明、风扇等用电设备进行控制,实现节能目的。(3)教室终端控制板实时显示本教室的课程安排,方便老师和学生选择教室。本课题将嵌入式系统、现场总线技术和网络技术结合起来,具体论述本系统的具体实现方法。包括系统设计,各个组成部分的硬件和软件设计。更多还原

【Abstract】 Today, the informationization and automatization level of the classroom is at a low level, and do not make full use of the resource of the classroom. This article had designed a classroom resources management system based on CAN bus and Embedded Internet. This system help us to rational use of the college classroom resources, and makes the students easy to know about the classroom teaching arrangements, and also to reduce energy consumption.We use the Embedded Systems technology, the network technology, the Fieldbus technology and computer software to design a classroom resources management system, which is based on CAN bus and Embedded Internet. This system contains three parts: classroom terminal control panel, the Access Point between internet and the CAN bus, and the computer software. Among them, the classroom terminal control panel is installed in every classroom. This system includes two networks. There is a CAN network between the classroom terminal control panel and the Access Point. And the computer software platform and Access Point are communication through the internet. The Access Point can use Ethernet and GPRS network to access the internet. This make the cabling more flexible and convenient.The system has three main functions:(1)Collected the light, temperature and other information of the classroom, this infomation can be access by the remote computer through the internet. (2) According to the user setting, the current time and the collected information, automatic control the lighting, the fans and other electrical equipments of the classroom. This is to reduce energy consumption. (3)Shows the classroom curriculum on a LED display for the students easy to select the classroom they needed.The subject combined of the embedded systems, fieldbus technology and network technology to realization of this system. This article including system designs, and the hardware and software design of That three parts.更多还原
