Carry positioning system

The utility model discloses a carry positioning system for automotive carries technical field, including rolling bed, transport trolley and intelligent frequency -variable controller, be equipped withthe reflector on the transport trolley, thereby it is equipped with actuating mechanism and can provides for intelligent frequency -variable controller with reflector cooperation work to roll the bedthe positional information of transport trolley in transportation process distance sensor, actuating mechanism include driving motor, rotary encoder and a plurality of roller train. The utility modeldiscloses an intelligence frequency -variable controller, it is through reading the positional information of distance sensor feedback with the rotational speed information of rotary encoder feedback, through the internal arithmetic, the accurate voltage frequency control information of output, control driving motor's rotational speed, thus realize two closed -loop control modes of carry positioning system. The utility mod
