【摘要】 机车监控装置负责监控机车的运行状态,是机车安全行驶的重要保障,故机车监控系统是否工作正常对于机车能否安全行驶具有很大的影响。要保证机车监控装置正常工作,就需要定期对其进行检测。目前使用的机车监控装置自动检测系统,只能进行整体测试,不能精确地检测其组成部分——微机控制插件板出现的问题。而单板测试系统尚处于开发阶段,还存在很多问题需要解决。本文提出了以工控机和PCI数据采集控制卡为硬件检测设备,以VC++6.0为软件开发平台,以自动检测技术为核心技术的机车监控装置自动检测系统的开发思路与实现方法。本检测系统借用了软件工程中的黑箱测试与白箱测试的思想,采用白箱测试的手段,对微机控制插件板进行深入检测;采用黑箱测试的手段,对微机监控装置进行全面检测,并将两种测试有机结合在一起,而不是机械组合。在硬件方面,本系统解决了PCI数据采集控制卡的SCSI-Ⅱ接口对微机控制插件板的DF₇总线接口的控制问题,包括协议转换,信号分配,电压调整等问题。在软件方面运用MFC应用程序框架与动态链接库技术,采用了界面程序与控制程序分离编写调试、联合运行的先进思想,提出了运行时刻决定语言环境的新想法,以数据库技术,多线程技术为辅助手段,完成了系统软件的设计。本检测系统不仅解决了此专用设备的检测工作,同时提出了一些新思路,可以应用到其他自动检测系统。更多还原

【Abstract】 The locomotive monitoring is charge of monitoring locomotive status, which is the important guarantee of the safe-traveling, so the locomotive monitoring is normal or not has great impact on the drive safely of the locomotive.To ensure the locomotive monitoring work normal, regular examination is necessary. The automatic detection system of locomotive monitoring currently using can only take overall examination, which can not detect the problem of its components—computer control plug-board. The single plug-board testing system is still in the development stage, and there are still many problems to be solved.This paper presents the thoughts and achieving methods of the detecting system of locomotive monitoring, which using IPC and PCI data acquisition and control card for hardware detection equipment, using VC + + 6.0 for software development platform, and using automatic detection technology as the core technology. The detection system using the white box testing and black-box testing perspective in software engineering, using white-box testing perspective to test the computer control plug-in boards deeply; using black-box testing perspective to test the locomotive monitoring comprehensively, and the two tests will be organic combined, not mechanically.In terms of hardware, this system solved the problem that how the SCSI-II interface of Advantech PCI data acquisition control card control the DF7 bus I/O interface of microcomputer control plug-in board, including protocol conversion, signal distribution, voltage regulation, and other issues. In terms of software, using MFC framework and dynamic link library technology, adopted the thought of whiting and debugging the interface procedures and control procedures separately while running them together. It also provides new ways to decide the language environment-in runtime environments. Using database technology and multi-threading technology as supplementary means to complete the design of the software.This detection system will not only solve this special equipment for the detection work, but put forward some new ideas which can be applied to other automated detection system.更多还原
