基于RFID的自动络筒机落纱小车对位系统分析与设计

ANALYSIS AND DESIGN OF AUTOMATIC WINDER DOFFING CAR ALIGNMENT SYSTEM BASED ON RFID

针对自动络筒机落纱小车自主开发需求,结合RFID最新发展状况,设计出基于射频识别RFID技术对落纱小车对位的系统,实现对落纱小车所处络筒机的锭位进行实时监测和数据传送。主要描述了系统的整体设计方案,并讨论了以MFRC632芯片为读卡模块的设计实例。将标签均匀粘贴在络筒机轨道上,读卡模块固定在沿轨道行驶落纱小车上,移动过程中读取当前锭位芯片的编号,确定小车所处锭位,将小车锭位信息传送至上位机控制小车移动速度。实验结果表明,该系统读卡模块安装距离在20 mm、角度0°、小车速度在110 mm/s的条件下,能100%完成对位,符合主流落纱小车的改造要求。

Aiming at the automatic winder doffer autonomous development requirements and in combination with the latest development trend of Radio Frequency Identification,the automatic doffer real-time alignment system based on RFID technology is designed to realize the real-time monitoring and data transmission of ingot coordinates of the doffing car. This study mainly describes the overall design scheme of the system,and discusses the design example with MFRC632 chip as tag reading module system. First,we uniformly pasted tag onto the winder doffing car orbit. The tag reader system was fixed on the track along the doffing trolley. Then,the system could read numbering of the current tag in dolly moving process and ensured the ingot position of the dolly. Moreover,the car coordinates would be transmitted to the PC in order to control the speed of doffer car. The experimental results show that this alignment system can 100% complete locate accurately,under the condition of the Reader and Tag installation distance 20 mm and parallel placement,doffing car speed up to 110 mm/s,which adapts to the current mainstream modification of automatic doffer car.
