摘　　要：设计了一种基于电涡流效应的自动导引车(AGV)导引传感器。该传感器利用电涡流原理,根据电感/数字转换器LDC1000采集外接线圈上的等效电阻的变化,得到传感器中心与金属胶带中心之间的偏移距离。详细介绍了系统硬件构成。在室内工作区域内铺设轨道上,对所提出的AGV导引传感器进行了实验测试,通过对实验数据分布特性图的分析结果证实了所设计传感器的可用性。所设计的传感器可用于AGV的导引,且具有高精度,易构建,易维护等特点。A kind of automated guided vehicle（ AGV） guidance sensor based on eddy current effect is designed.The proposed sensor utilizes the eddy current principle,according to inductor digital converter LDC1000 acquire changes of equivalent resistance of the external coil,obtain offset distance between the sensor center and the metal tape center. Describe the system hardware configuration in detail. In-room work areas laid on track,the proposed AGV guidance sensor is experimentally tested. Analysis of the distribution of the results of the experimental data confirms availability of the designed sensor. The sensor can be used to guide the AGV and has characteristics of high precision,easy to build and maintain.
