Undergraduate Construction Materials Laboratory Computer-Based Instrumentation

该项目的目的是向土木工程本科生教授基于微型计算机的实验室仪器和数据分析技术。这包括选择仪器的类型和特点，以及使用统计数据分析方法。将使用的主要仪器是测量设备，如LVDT、压力传感器、引伸计、信号调节器、模数转换器、带硬盘的IBM286计算机、绘图仪、打印机和相关软件。这些设备的应用将在建筑材料方面的大三本科土木工程必修课程中进行。学生将参与到荷载和变形的电子监测，观察实时数据显示，使用微型计算机处理和分析数据，并产生硬拷贝报告和曲线图。这个项目意义重大，因为它将使土木工程专业的学生熟悉现代基于微型计算机的电子仪器和微型计算机。本教学模块是二年级土木工程计算技术导论课程的逻辑延伸，在该课程中，学生被介绍各种软件工具和数值分析技术。通过这种方式，学生将获得当今土木工程专业所需的软件和硬件计算机技能。此外，这种设备进一步推进了部门规定的目标，即“用最先进的电子数据采集系统替换过时的设备……ı和！，强调沟通技能、计算机技能和统计技能。”

The aim of the project is to teach microcomputer-based laboratory instrumentation and data analysis techniques to civil engineering undergraduates. This includes the selection of the type and characteristics of instrumentation, and the use of statistical data analysis methods. The major instruments to be utilized are measurement devices such as LVDT's, a pressure transducer, an extensometer, signal conditioners, an analog-to-digital converter, an IBM 286 computer with hard drive, a plotter, printer and associated software. The applications of the equipment will occur in a required junior level undergraduate civil engineering course in construction materials. The students will be involved in monitoring load and deformation electronically, observing real time date display, using the microcomputer to manipulate and analyze the data, and to produce hardcopy reports and plots. The project is significant because it will familiarize civil engineering students with modern electronic microcomputer-based instrumentation and microcomputers. This instructional block is a logical extension of the sophomore level Introduction to Computational Techniques for Civil Engineering Course where students are introduced to various software tools and numerical analysis techniques. In this way the student will acquired both software and hardware computer skills necessary in today's civil engineering profession. Further, this equipment furthers to stated departmental goal of "replacing obsolete equipment with state-of- the-art electronic date acquisition systems...ıand! to stress communication skills, computer skills and statistical skills."
