Abstract
在分析了目前国内外钢轨磨耗检测技术的特点及方法的基础上，结合实际需求，提出了基于PSD位置传感器的钢轨磨耗检测方法。利用光电检测技术、微处理器技术及数据处理技术完成了检测装置的开发，并进行了试验测试，结果表明检测系统具有检测速度快、精度高、性能可靠的特点。开发的装置便于携带、具有人机对话功能，解决了目前检测设备普遍体积过大、携带不方便及检测效率低等问题。 In order to meet the actual demand, a new detection method of steel rail abrasion based on PSD (Position Sensitive Device) is proposed after research current characteristics and methods of steel rail abrasion detecting equipment at home and abroad. Developed detecting device uses photoelectric detector, microprocessor and data analysis. Finally, the paper has carried on the experiment and analyzed the results; throughout the experiment, it can conduct the detector with high speed and accurate data and reliable performance. The developed device is portable and accurate detector with human machine conversation function. It improved many disadvantages of hodiernal detectors, such as low-efficiency, big size, unwieldy mass.
