【摘要】 本文详细论述了“网络中央控制系统”产品的软硬件实现方案。该中央控制系统属于新一代系统,比目前大量使用的产品有了很多实用的功能改进和技术创新,是新一代产品的优选产品。解决了多媒体教室增加和电教管理人员缺乏的矛盾,实现多媒体教室设备的自动化管理并简化设备运用的复杂程度。 课题进行中做了大量的软硬件工作,主要解决了以下重要问题: (1) 选择价格、性能都较为合适的器件,设计满足系统要求的硬件系统; (2) 制作灵活、紧凑的TCP/IP通信协议栈程序; (3) 设计友好的用户接口; (5) 实现USB、串口和网络接口命令的无缝结合; (6) USB接口的固件程序设计; (7) 系统抗干扰设计。 在完成系统整体应用功能设计的同时,还完成了以下几方面的特色设计: (1) 采用网络接口,使中央控制系统成为网络上的一个节点,实现了远程监控与管理; (2) 该套网络中央控制系统采用了USB2.0和串行接口的双重接口方案,简化了设备的操作难度,并解决了相关的技术和成本问题,具有廉价、方便、快捷等优点; (3) 采用高性能、低功耗的ARM7嵌入式处理器,在降低降低了系统的成本同时,加强了整个系统的数据处理能力和稳定性。 本课题所研制的网络中央控控制系统是一款新颖实用的产品,相信该产品未来可以成为上一代中央控制系统的优选替换产品。同时,本课题作为一个实用工程,设计中的很多方法和思想为今后同类课题的研究提供了有价值的参考。
【Abstract】 The thesis discusses the hardware and software implementation of a Control System based on Ethernet in detail. The system with many useful features can be classified to a new generation. It is a preferential selection for the control system of next generation, because it has solved the conflicts between the increase of multimedia classroom and the lack of administrators. Furthermore, it has realized automatic management of multimedia classroom and simplified the complexity of equipment application.We have done a lot of hardware and software work to solve some crucial technical problems as follows:(1) We select proper apparatus to meet the system requirement of hardware system.(2) We program a compact TCP/IP communication protocol stack.(3) We design a friendly user interface.(4) We combine the USB, serial interface and Ethernet interface commands.(5) We design the USB firmware program.(6) We realize the design of anti-jamming. There are several innovations in the project.Firstly, we adopt an interface of Ethernet to realize remote control.Secondly, we adopt several interfaces, such as USB2.0 and UART interface, to simplify the difficulty of implementation and solve the technical problems.Thirdly, we adopt ARM7 MCU as the control core of the system, which evidently improves the whole performance of the system and reduces the cost.At last we make a conclusion to the thesis and we believe that the new control system will replace the old generation system in the future. At the same time, as a practical project, there are some valuable ideas and ways for future research.
