[0002] In fully automatic storage cranes, the program structure and optimization algorithm are the core technologies to ensure fully automatic operation, safety, reliability and high efficiency. Most of the current storage cranes are manually operated, and the operator has a high work intensity and is prone to fatigue. Some install PLC The current crane is only limited to meet the functions of the crane itself, does not have the function of fully automatic operation of the crane, and cannot form a coordinated overall operation mechanism with the warehouse. The current storage crane, because there is no PLC, the judgment of the sensor, the preset function, the operator Inattention can easily cause damage to warehouse items, bumps, long pick-and-place cycles for single items, low efficiency, and no full-automatic functions. , The fully automatic program optimization algorithm for storage cranes with a wide range of applications is of great significance

Embodiment Construction
[0018] The specific implementation process of the present invention is described as follows below:
[0019] A fully automatic program optimization algorithm for storage cranes, which includes a Pick process and a Place process, including the following steps:
[0020] 1) Establish a mathematical model: create a mathematical model of the step-by-step approximation method, and perform a one-key positioning function for the crane, so that the crane can run to the highest point before the operation, and there is no callback positioning of the crane; a mathematical function model is established to automatically generate the crane every time it runs The passing point and route of the path, so that every time the crane is working, the hook can safely lift the goods according to the set operating route;
[0021] 2) Development of PLC program: Design an open program to enable the crane to receive the guidance of the running path of the upper computer, automatically complete the lifting ...

The invention relates to a fully automatic program optimization algorithm for a storage crane, which includes the following steps: 1) Establishing a mathematical model: creating a mathematical model with a step-by-step approximation method to perform a one-key positioning function for the crane; establishing a mathematical function model to automatically generate each time the crane Passing points of the running path; 2) Development of PLC program: Design an open program to enable the crane to receive guidance from the upper computer running path, programming in the structured programming language SCL; install the wincc process monitoring system application; set the status word in the PLC SWO, the status word SWO is used to identify the operating status of the crane. Each time the crane operates, the corresponding status word verification is set; 3) Self-learning path storage development: secondary judgment and feedback of the crane's operating status; timely development of PLC programs With storage and self-learning path functions, the invention has the advantages of improving operating efficiency, high degree of automation, comprehensive functions, easy operation, and wide application range.
Description
technical field [0001] The invention belongs to the technical field of storage crane control methods, in particular to a fully automatic program optimization algorithm, in particular to a fully automatic program optimization algorithm for storage cranes. Background technique [0002] In fully automatic storage cranes, the program structure and optimization algorithm are the core technologies to ensure fully automatic operation, safety, reliability and high efficiency. Most of the current storage cranes are manually operated, and the operators work hard and are prone to fatigue. Some install PLC The current crane is only limited to meet the functions of the crane itself, does not have the function of fully automatic operation of the crane, and cannot form a coordinated overall operation mechanism with the warehouse. The current storage crane, because there is no PLC, sensor judgment, preset function, the operator Inattention can easily cause damage to warehouse items, bumps, ...
