ND5型内燃机车的粘着控制系统 （上）

ND_5型内燃机车的粘着控制系统,是根据轮对间的速度差及各轮对的加速度值来判别机车是否发生空转或滑行的,并由此而采用适当的措施来恢复粘着。本文详细地分析了该系统的工作原理,且深入地阐述了系统的电路结构与特点。     

Driver requirements and road traffic informatics

Initially the driver's role as a link in the driver-vehicle-road-traffic control-chain is discussed in a historical perspective. The gradual changes and the advantages and problems arising from these changes are discussed from behavioural point of view.Then the driver tasks are analyzed. A separation is made between trip planning, navigation, road following, traffic interaction, rule compliance, other than traffic tasks, car handling and speed choice. The relations between and the weights of these subtasks are discussed. Some existing driver behaviour models are reviewed in relation to the above mentioned tasks.Finally an effort is made based on the analyses of driver tasks and driver models to specify some general and some more specific potential advantages and problems with expected future RTI-systems.     

ROV—遥控潜水器数据传输系统

本文介绍了系缆遥控潜水器（ROV）数据传输系统的信息容量、速率和水中运动载体的时间响应；分析了半双工传输系统与时钟节拍；交替使用8位、12位模拟量数字转换，保证了ROV运动控制精度．在实行水面、水下信息通信的数据传输系统中，由于用绞线对替代了诸多导线，缩小了脐带电缆直径，减少了脐带电缆水中运动时受到的阻力，因而提高了系缆遥控潜水器操纵机动性和下潜深度．     

Japanese perspective of driver information systems

A perspective view of of Japanese R&D activities of Driver Information Systems is given from the standpoint of developing joint projects by public and private sectors. First, a brief history of the R&D activities is illustrated from above mentioned standpoint. Then, two major projects, AMTICS and RACS, and the social backgrounds of these projects are explained. In order to give a clear idea of both projects some technical details are treated.Based on the history and the present status of the developments, the basic design conceptions of Japanese Driver Information Systems are explained and several factors or reasons which have influenced to the design conception are discussed. Then, the promoting systems of the R&D activities are generally explained and present status of the projects and future problems in developing more advanced systems are also handled. A brief discussion on the establishment of international standard is also mentioned as a final comment.     

船舶主机冷却水系统的建模与节能型控制研究

在对船舶主机高温淡水冷却水系统的各主要器件建立各自的数学模型的基础上,对其整个系统建立了数学模型.然后以主机高温淡水冷却水系统作为研究对象,提出了在此系统中采用神经元自适应控制方式替代传统的PID(比例积分微分)控制方式进行水温调节,以达到改善控制并节约能源的目的.最后以仿真结果说明了神经元自适应控制方式具有良好的适应性与抗干扰性,它比PID控制方式更适用于主机冷却水温度调节系统.     

嵌入式ARM-Linux系统在便携式测流仪中的应用研究

随着嵌入式技术不断发展，微处理器已被应用于各种电子仪器的设计当中。近年来，ARM嵌入式微处理器技术发展迅速，并以其高性能，低功耗的特性成为嵌入式领域应用最广泛的32位微处理器。本课题将ARM微处理器技术率先引入到测流仪器的设计中来，采用基于ARM920T内核的AT91RM9200微处理器作为系统CPU；同时在软件方面，采用功能强大而源码免费开放的Linux系统，组成了基于ARM微处理器的Linux系统（简称ARM-Linux系统），并对这种先进的嵌入式系统在多普勒测流仪中的应用进行了研究，以期提高多普勒测流仪的整体性能。     

和谐交通的伦理构建:系统、结构、层次

构建"和谐交通"是系统性的价值目标,需要以和谐伦理为导向,从宏观上审视现代交通关系的结构及其特征,研究交通主体之间、交通客体之间、交通主客体之间的基本关系及其状态,通过一系列调整优化,使之不断地从冲突走向和谐。
