天车借助于各种定位技术获取自身和工作环境中的库位、仓位、固定料位等的位置信息，实现精准定位，使无人天车按照要求自行前往指定的位置，并与各种移动设备和生产线进行安全连锁，是一种综合性的信息管理系统，使厂房内更加规范化，效率化。

　　With the help of various positioning technologies,the crown block obtains the location information of its own warehouse,warehouse and fixed material level in the working environment,realizes accurate positioning,enables the unmanned crown block togo to the designated location by itself as required,and carries out safety interlocking with various mobile devices and productionlines.It is a comprehensive information management system,which makes the factory more standardized andefficient.

　　定位技术：1长量程磁致伸缩绝对式位移测量系统

　　Positioning technology:Long-range magnetostrictive absolute displacement measurement system

　　长距离的磁致伸缩绝对式位移系统是专为超长距离运动物体高精度绝对式位置测量而设计的，系统可提供2.3公里范围内绝对精确和可靠位置信息。系统特别适合应用于堆料天车、桥式起重机、装卸桥、龙门吊、倒车控制以及起重机和小车行驶等场合。

　　长距离的磁致伸缩绝对式位移测量系统是基于磁致伸缩位移传感器基础开发的长距离定位系统，系统一般由磁致伸缩位移传感器、信号转换模块及若干个磁标组成，可实现在恶劣条件下高精度测量，重复精度可达±0.5mm,对雨水、粉尘、冲击、振动等不敏感，可在室内、室外等大部分工业环境下使用。

　　The long-distance magnetostictive absolute displacement system is specially designed for high-precision absolute position measurement of long-distance moving objects,and the system can provide absolutely accurate and reliable position information within 2.3 kilometers.The system is especiallysuitable for stacking crane,bridge crane,loading and unloading bridge,gantry crane,reversing control,crane and trolly driving and other ocasions.

　　The long-distance magnetostrictive absolute displacement measurement system is a long-distance positioning system based on magntostrictivedisplacement sensor.The system is generally composed of magnetostitive displacement sensor,signal conversion module and several magneticmarkers,which can achieve high-precision measurementin harsh conditions,with a repeatability ofup to 0.5mm,and i insensitive to rain,dust,shock andvibration,and can beused in mostindustrial environments such as indoor and outdoor.

　　Through the function box,the system can provid diferent types of output intefaces,such as SS/Profinat/CAN/Modbus/EtherCat/Analog /profibus-

　　DP,which can beused after being adapted to the user's existing data acquisition module,and the use is extremely simple.
