Ship unloader control system and control method

Abstract

The invention discloses a control system and a control method for a ship unloader. The control system comprises a processor, a cabin and material collection system, a grab bucket navigation and positioning system and a control unit, wherein the cabin and material collection system is used for performing image collection on the position of a cabin and the distribution of materials and sending collection information to the processor; the grab bucket navigation and positioning system is used for detecting the position information of a grab bucket and sending the position information to the processor; the processor is used for optimizing the movement path of the grab bucket according to the collection information, generating a control signal containing the movement path and sending the control signal to the control unit; the control unit is used for receiving the control signal from the processor and the position information of the grab bucket and controlling the motion of the grab bucket so as to complete the reciprocating discharging of the grab bucket. By virtue of the control system and the control method, the material grabbing and reciprocating movement efficiency of the grab bucket is improved, the probability of error collision among the grab bucket, the cabin and a ship unloader body is effectively reduced, the operation safety and the intelligence level are improved, and the service life of the ship unloader is prolonged.

Description

technical field [0001] The invention relates to the technical field of bulk cargo unloading in ports, in particular, to a control system and method for a ship unloader. Background technique [0002] Since the 21st century, with the intensification of global trade, global bulk transportation has been greatly developed. According to Wang Naifeng's "2013 International Dry Bulk Shipping Market Outlook" published in "Water Transport Management", the dry bulk shipping volume of the world's major bulk material exporting countries in 2013 was 29.5 tons, an increase of 5.1% compared with 2012, of which iron Ore, coal, etc. grew rapidly. [0003] The increase in the volume of bulk cargo has higher requirements for its handling equipment. According to the different ways of material transportation, material transportation equipment is mainly divided into two categories: continuous ship unloader and discontinuous ship unloader. The continuous ship unloader can only be used in a closed...
