Abstract

The invention relates to a railway car positioning system and method based on an encoder and racks, particularly relates to a positioning system based on the encoder and the racks, and the positioning system can control a non-adjustable-speed motor to achieve high-precision positioning. The invention provides the railway car positioning system and method based on the encoder and the racks, and the system and the method are accurate in positioning and are short in positioning control time. The railway positioning system based on the encoder and the racks includes a railway, and a railway car is arranged on the railway. The structural features of the railway positioning system are that: a plurality of racks are arranged on the railway in the railway length direction; the numbers of teeth of all the racks are different; one rack is corresponding to one work target position; the railway car is provided with a gear which is engaged with the racks; the center shaft of the gear is connected to a rotatable signal input end of the encoder arranged on the railway car; and a signal output port of the encoder is connected to a signal input port of a PLC.
