The Design of a Control Device for Precise Berthing of Travelling Crane

Aim\ To control travelling crane automatically going to and fro precisely between two fixed positions for loading and unloading goods. Methods\ Using infrared photoelectric couple to detect a shade block to obtain the positioning signal. To advance the performance of the detector, with singlechip processor as controller and using software filter technology. Results\ Through practical application, the positioning error of the device is less than 2 cm. The device has a good antinoise ability. Conclusion\ Using noncontact photoelectric sensor, the circuit has a longer life, a lower fault rate and a precise berth.
