Abstract

The invention discloses a positioning method of a mobile target in a fixed region and\or a fixed line. The positioning method comprises the steps that (1) the fixed region and\or the fixed line whichthe mobile target passes through is divided into K segments, N position sensors are arranged in each segment, each position sensor comprises a resistor, and the N resistors in the N position sensors in each segment are connected in series through a wire; (2) in order to ensure the uniqueness of resistance values of the resistors, a constraint condition is set for the N resistors in the N positionsensors in each selected segment; and (3) when the mobile target passes through a certain segment, the resistors in one or more position sensors in the segment are subject to a short circuit, a controller collects changing total resistance values in the segment in real time and performs lookup comparison, and therefore the specific segment which the mobile target passes through and the specific position of the mobile target in the segment are obtained. Through the positioning method, the wiring amount in construction is less, the structure is simple, cost is low, maintenance is convenient, andtherefore the positioning method has high popularization value.

Description

technical field [0001] The invention relates to a positioning method, in particular to a positioning method for a moving target in a fixed area and / or a fixed line. Background technique [0002] At present, within a specified range, positioning such as moving vehicles or moving objects has become the next active research field. Among the several commonly used positioning methods, such as using GPS or Beidou system combined with tracking guidance for positioning, there are often disadvantages of limited use of the environment due to the serious attenuation of communication signals passing through the ground; and the use of cameras to collect images of moving targets for image recognition The positioning under the background often has the disadvantages of complex algorithms, high cost, and slow execution speed; if the matrix positioning recognition combined with row selection and column selection is used, there will be too many connections, high maintenance costs, and it is no...
