列车斜契检修质量直接影响着列车的正点、安全运行。详细介绍了使用位移传感器实现对斜楔有关尺寸进行检测及分拣的原理, 采用位移传感器和ADAM5510 工控机实现对斜楔的自动检测、分拣控制。整个系统实现成本较低, 运行可靠, 检测精度高。 关键词: 检测; 分拣; 位移传感器; ADAM5510 Abstract : Reconditioning quality of train oblique - wedge directly affects its running safely and on schedule. Implement principle of size detection and selection of oblique - wedge by making use of displacement sensor are introduced in detail. Automatic detection and au2 tomatic selection of oblique - wedge are implemented by adopting displacement sensor and ADAM5510 industrial computer. The whole system is of low cos t of implementation , trustiness in run and high accuracy in detection. Key words : detection ; selection ; displacement sensor ; ADAM5510
