【摘要】 计算机硬件和软件技术的飞速发展，使工业控制系统领域的计算机技术发生了很大的变化。分布式控制系统(DCS)，由于其功能分散、负荷分散、故障分散、管理集中和易于扩展的特点得到广泛的应用。随着现场总线技术的成熟，DCS发展为具有更高可靠性、更高效率的现场总线控制系统(FCS)，也成为工业控制系统的重要发展方向。 MSCIS(Marine Simulation & Control Interface System)是为现代船舶轮机仿真训练器开发研制的一套分布式智能输入／输出接口控制系统。它实现了仿真系统接口计算机及控制盘台或其它硬件间的数字量／模拟量的相互转换及传输。MSCIS接口系统继承了DCS的特点和优点，又具有FCS系统的特性。它采用分布式的结构，包括一个接口计算机和数个I／O接口机箱，形成一个现场总线网络。接口计算机作为整个现场总线网络的管理者，配置和管理通信链路中I／O接口机箱运行；I／O接口机箱则通过机箱内的不同功能的多个板卡，连接控制盘台或其它硬件设备，分散控制接口系统的各个输入输出通道。 MSCIS接口系统输入／输出通道可自由扩展、灵活组态，系统具有功能全面、可靠性高、实时性好、可移植性强、性价比高的优点，也可用于其它系统仿真工程、工业控制工程等领域。MSCIS智能化接口控制系统的研制，是我校独立研制接口系统的一次尝试，不仅锻炼和提高了自主开发船舶仿真训练器输入／输出接口系统的研发能力，而且降低了整个仿真系统的硬件成本，为实现整个仿真系统自主化研制跨出了重要的一步，具有很大的现实意义和经济效益。目前MSCIS接口系统中的各个板卡包括基于CAN总线智能通信卡和控制卡，模拟量输入卡，模拟量输出卡及数字量输入／输出卡都已调试运行正常，基本实现MSCIS接口系统研制开发目标。 论文是在研制MSCIS接口系统的CAN总线智能通信卡(CCOM)和模拟量输入卡(AI)基础上完成的。整个研究工作从MSCIS接口系统板卡的硬件设计和软件编程两方面展开。系统研制开发过程主要分两大部分： 第一部分：应用Protel99设计软件设计模拟量输入卡的硬件原理，规划设计印刷电路板图并送厂制作板卡电路板；模拟量输入卡硬件制作和调试；编写模拟量输入卡汇编语言控制程序，在SUPER ICE16仿真器上编译调试；编译后的控制程序在SUPER ICE16仿真器上以在线方式仿真调试；仿真调试成功的控制程序烧入EPROM芯片，进行系统EPROM仿真调试。 第二部分：设计CAN总线智能通信卡的硬件电路，应用Protel99设计软件绘制原理图及印刷电路板图，并送厂制作板卡电路板:智能通信卡硬件制作和CAN总线芯片调试;编写通信卡控制及CAN总线通信汇编语言程序并编译;在SUPER ICE16仿真器上在线仿真调试控制程序;连接系统控制卡，仿真调试CAN总线通信程序;程序烧入EPROM芯片，进行系统EPROM仿真调试;接口系统驱动程序及测试软件调试。 论文介绍了智能化MSCIS接口控制系统的组成、工作原理，系统的硬、软件技术和设计经验。硬件上，内容涵盖了模拟量输入卡、以N总线智能通信卡的硬件电路设计、抗干扰技术和硬件升级方案;软件上，论文介绍了模拟量输入卡控制程序设计，CAN总线智能通信卡控制程序设计思路和CAN总线通信的实现方法，并介绍了MSCIS接口系统驱动程序和测试软件。更多还原

【Abstract】 With the rapid development of hardware and software technology, computer technology in the field of industry control system has great improved. Distributed control system (DCS), with the characteristic of centralization of its management and the distribution of its functions, burthen and malfunction, is widely used in the process of modern industry. But with the Field Bus Technology putting into use, DCS has developed into Field Bus Control System (PCS) with higher reliability and high efficiency. FCS has become important developing direction of industry control system.MSCIS (Marine Simulation & Control Interface System) is a set of distributed intelligent Input/Output interface control system developed for the modern marine engine simulator. It realizes the data conversion and transport of simulation system interface between computer and control panels or other hardware. It succeeds to the characteristic and strongpoint of DCS, and has new characters of FCS. It adopts distribution pattern, which composes of one interface computer and several I/O interface crates, organizing a Field Bus network. As the manager of whole Field Bus net, The interface computer sets and controls all the I/O interface crates on the communication chain; and I/O interface crates connect with control panel or other hardware devices using different function cards, dispersedly controlling each input and output channels of the interface system.MSCIS interface system is provided with complete function, good real time, high dependability, high replantation ability and high ratio of capability to price. I/O channels of system can be expended freely and each channel can do flexible configuration. Besides, it can be used in the field of other system simulation projects and industry control projects. The research on MSCIS intellectualization interface control system is an attempt to study the interface system independently. That not only improves the ability to develop modern marine engine simulator I/O interface system but also decreases the hardware cost of simulator system; what’s more, it contributes to realize independent research on whole system of the simulator with great realistic meaning and economic meaning.
