线引导(Wire Guidance)
非接触式指导；区别在于光学和感应引导，它们又可以分为感应主动引导和感应被动引导。感应式主动引导需要在地板上安装一根导线，高频电流流过该导线。产生同心磁场，引导工业车辆。
英文介绍
Non-contacting guidance; to be distinguished are optical and inductive guidance, which in turn can be divided in inductively active and inductively passive guidance. The inductively active guidance requires a guide wire installed in the floor, through which a high-frequent electric current is flowing. A concentric magnetic field is generated, guiding the industrial truck.
