基于LABVIEW的公交站点显示系统的设计
摘要
交通的信息发展对于我们来说,是体现文明社会发展的一个标志。本课题利用先进的技术理念提供了一个交通信息网络化,自动化的解决方案。
首先,本课题介绍了虚拟仪器概况及其发展背景;通过对虚拟仪器的学****和研究,运用软件工具,实现公交站点显示系统的模拟。实现系统软件设计思路是:利用LABVIEW中的各种控件,实现模拟汽车站点显示报站及温度数据采集显示,车速,人数系统时间的显示。利用虚拟仪器的优越性实现了基于操作系统下的交通终端服务系统的展示部分。
其次,运用软硬件工具,实现数据的实时采集,下位机以STC89C52单片机为核心的硬件电路处理数据,然后通过RS232串行通讯传送到上位机,上位机的数据通过LabVIEW编程进行提取并处理体现了虚拟仪器强大的硬件结合能力。
再次,利用WEB软件发布功能,实现公交行车信息的共享发布。为今后发展数字信息化网络交通的目标理想提供了一个可行的设计解决方案。
综上,因LabVIEW图形化的编程界面,良好的人机交互界面,方便的硬件连接性能,它对开发者来说很受欢迎;LabVIEW的技术更新很快,相信它不仅在交通信息方面会有很大的应用,而且会在越来越多的领域发挥出更大的作用!

The Bus Station Display Based On LabVIEW
ABSTRACT
Traffic information development for us, is the embodiment of civilization and social development of a mark. The issue of the use of advanced technology concepts to provide work of transportation information, automation solutions.
Firstly, this paper introduces the general situation and development background of virtual instrument based on virtual instrument; study and research, use of software tools, to achieve public transit station display system simulation. Realization of system software design idea is: use a variety of LABVIEW control, simulation of vehicle site display station and temperature data acquisition and display, vehicle speed, number of system time display. Using the advantages of virtual instrument based on the realization of the operating system of the traffic terminal service system display part.
Secondly, the hardware and software tools, real-time data acquisition, the puter takes the STC89C52as the core hardware circuit processing data, and then through the munication to PC, PC data through the LabVIEW programming for extracting and processing embodiment of virtual instrument powerful hardware binding capacity.
Again, use WEB software release function, realize the information sharing issue bus. For the future development of digital information work traffic goal provides a feasible design solutions.
Therefore, due to the LabVIEW graph
