摘要
在有轨机车自动控制中,需要对移动机车位置进行精确测量,为此设计了一套感应无线位置检测系统。该系统是基于电磁感应原理,通过检测天线箱线圈与编码电缆的感应电动势相位和幅度,得到移动机车的位置。介绍了感应无线位置检测系统的基本框架,阐述了系统基本工作原理,推导了位置检测公式,设计了位置检测电路模型,并进行了无线感应位置检测实验。结果表明:感应无线位置检测系统检测精度高,抗干扰能力强,可满足移动机车精确定位的要求。
In automatic control of rail locomotives,it is necessary to make accurate measurement of the location of mobile locomotive,therefore a system for position detection with induction radio is designed.Based on the principle of electromagnetic induction,the mobile locomotive location can be acquired by detecting the phase and amplitude of induced EMF which is between sending coil and coded cable.The basic framework of the system is introduced and the basic principle is described.Some detection formulas for position detection are deduced,the circuit model of position detection is designed,and some experiments for position detection with induction radio are carried out.The results show that the system for position detection with induction radio has better anti-interference performance,higher detection precision,and can meet the requirements of precise positioning mobile locomotive.
