Corresponding device for actual position of unmanned crown block and absolute positions of saddles and method

Abstract

The invention relates to a corresponding device for the actual position of an unmanned crown block and the absolute positions of saddles and a method. The device comprises an industrial personal computer, a wireless network device, a programmable controller, a cart laser ranging device, a trolley laser ranging device, a laser ranging reflector, a counterweight device and a handheld laser ranging device; the industrial personal computer is wirelessly connected with the programmable controller to read cart and trolley laser ranging data and cart and trolley frequency converter data; and reservoir area X-axis and Y-axis distance and original point position and the distance from an original point to saddle center points are accurately measured and calculated through the handheld laser distancemeasuring device and the counterweight device, and therefore the positions of the saddles in the reservoir area are calibrated. According to the device and the method, the problem that a large errorexists between the absolute positions of the saddles in the reservoir area and the actual position of the unmanned crown block is fundamentally solved, the working efficiency of position calibration of the saddles in the reservoir area is greatly improved, a large amount of repeated position calibration work caused by inaccurate positions is avoided, and the accurate, stable and safe operation ofthe unmanned crown block is guaranteed.

Description

technical field [0001] This patent application belongs to the technical field of automatic control of unmanned cranes, and more specifically relates to a corresponding device and method for the actual position of unmanned cranes and the absolute position of saddles in storage areas. Background technique [0002] During the normal unloading operation of unmanned cranes, the more accurate the correspondence between the actual position of the crane and the saddle position in the warehouse area, the more accurate the distance traveled and the position reached by the unmanned crane, and the safer the unloading operation process; Saddle calibration method in the reservoir area: The saddle position calibration in the reservoir area is to calibrate one diagonal saddle in each small area, calculate the coordinate positions of other saddles through the secondary calculation model, and then calibrate one in the middle of the area or two saddle positions for verification, if the deviati...
