摘要
文章是对超声技术在车型车位判定系统中应用的一个总结。为解决机车车厢号码自动识别,必需首先解决机车车厢号码同步记录问题,文章详细论述了运用超声测距和设定时间窗相结合,解决不同车型车位同步判定的方法。对系统的工作原理、组成、功能、工作过程等都给予了详细的叙述,并给出了各主要设计参数。最后给出了现场应用结果。
The application of ultrasonic technique in the judgement system for the type and position of a locomobile is summarised in this paper. It is essential that the sychronous record of the carriage numbers is first solved in order torecognize the numbers automatically. The use of the combination of ultrasonce renging and time threshold setting, and the synchronous judgement method for the types and positions of different locomobiles, are gone into datails. It also states the principle, the composition, the function and theprocess of the system. The main design parameters and the in siteresults abtained are finally given.
