Hoisting equipment alignment system and method

Abstract

The invention discloses a hoisting equipment alignment system and method. The system comprises a data acquisition module, a hoisting appliance pose detection module, a target position pose detection module, and an alignment module, wherein the data acquisition module comprises four groups of data acquisition equipment respectively arranged on four terminal actuators of a hoisting appliance; the four groups of data acquisition equipment are used for acquiring image data and inertial navigation data of the hoisting appliance; the hoisting appliance pose detection module is used for obtaining a real-time pose of the hoisting appliance; the target position pose detection module is used for obtaining a real-time pose of a container; the alignment module is used for determining a real-time relative position relationship between the hoisting appliance and the container according to the real-time pose of the hoisting appliance and the real-time pose of the container; and after carrying out low-point alignment on the terminal actuator closest to the container and a corresponding target lock hole, the other terminal actuator and the corresponding target lock hole are then aligned. Accordingto the hoisting equipment alignment system and method provided by the invention, through providing low-latency high-precision hoisting appliance pose information, the alignment success rate is improved, so that the container is automatically loaded and unloaded, and the operation efficiency of hoisting equipment is further improved.

Description

technical field [0001] The invention relates to the field of crane loading and unloading, in particular to a positioning system and method for hoisting equipment. Background technique [0002] Traditional crane operations use manual operations to load and unload containers, and the cranes are manually operated to control the containers. When the alignment fails, manual adjustments are required according to the actual situation. The operation efficiency of this method is not high, and due to manual intervention, the entire operation will be affected by human beings, resulting in a greatly increased risk. [0003] During the loading and unloading process of the container, the spreader is the specific execution equipment for the operation of the container. During the loading and unloading operation using the spreader, due to the positioning error of the encoder, the deformation of the pull rope, and the influence of the weather environment, etc., the spreader will cause Unexpe...

The operation efficiency of this method is not high, and due to manual intervention, the entire operation will be artificially affected, resulting in a greatly increased risk

[0003] During the loading and unloading process of the container, the spreader is the specific execution equipment for the operation of the container. During the loading and unloading operation using the spreader, due to the positioning error of the encoder, the deformation of the pull rope, and the influence of the weather environment, etc., the spreader will cause Unexpected changes in the pose of the spreader, resulting in the failure of alignment between the spreader and the target container
