Abstract (en)
[origin: EP0098896A1] The invention relates to a position locating system for detecting a mobile object on a predetermined route. This system includes a twisted-pair type inductive radio-frequency lines (1) which are arranged along the route of the object. The inductive lines (1) comprise a plurality of crossings (3, 4) and intervals of specific two different lengths p1 and p2 within an area necessary for detecting the absolute position of the object with value of p2 being larger than the value of p1. The position locating system according to the invention is available even for the place where it is difficult to install multi-pairs of the inductive lines and it is inexpensive for the production and simple for the installation.
