Abstract
Description
Technical Field
[0001] This invention relates to the field of port logistics automation control technology, and in particular to an integrated collaborative control method for heterogeneous equipment in port operations throughout the entire process. Background Technology
[0002] With the growth of global trade, port throughput is constantly increasing, placing higher demands on operational efficiency. Port operations involve a variety of equipment and systems, such as tippers, ship loaders / unloaders, belt conveyors, and stacker-reclaimers. These devices are heterogeneous in function, structure, and control. Traditional port operation methods suffer from insufficient coordination between equipment and information silos, resulting in low operational efficiency. In port operations, the length of waiting time directly affects operational efficiency.
[0003] Therefore, in order to achieve optimal resource allocation, a technology is needed that can break down barriers between equipment, unify the management and collaborative control of heterogeneous equipment, and realize integrated collaborative control. Summary of the Invention
[0004] To address the aforementioned technical problems, this invention provides an integrated collaborative control method for heterogeneous equipment in port operations. This invention integrates knowledge from multiple disciplines, including automation control, computer science, and information technology, aiming to solve the problem of information silos among heterogeneous equipment in port operations. It achieves information sharing, data interaction, collaborative operation, and precise control among equipment, thereby improving the overall efficiency of port operations.
[0005] The technical means employed in this invention are as follows: A method for integrated collaborative control of heterogeneous equipment in port full-process operations includes: real-time acquisition of port equipment operation data and construction of equipment information models and standardized data models; acquisition of full-process operation data information and preliminary screening of workflows based on the starting and ending point locations of the full-process operations; judgment of the current workflow and determination of the optimal operation process; sequential execution of self-check operations according to the optimal operation process and equipment start-up order; control of each device to complete the full-process operation according to the optimal operation process; and generation of operation logs based on the completion status of the full-process operation to achieve full-cycle traceability of the full-process operation.
[0006] Furthermore, the operational data of the port equipment includes equipment type, quantity, start-up time, energy efficiency indicators, and spatial location.
[0007] Furthermore, the data information of the entire process includes the start position, end position, target position and related equipment details of the operation. Based on the data information of the entire process, the equipment information model and the standardized data model are invoked to initially screen the workflow.
[0008] Furthermore, the judgment of the current workflow specifically includes: Determine if there are multiple optional work processes in the current workflow. If there are no multiple work processes, proceed directly to the next stage of equipment self-inspection based on the data information in the preset process. If there are multiple feasible work processes, comprehensively evaluate and decide on the optimal work process based on the equipment status, load capacity, operation time, and energy consumption dynamic parameters in each work process.
[0009] Furthermore, during the self-testing process, a comprehensive judgment is made by combining the real-time status information of the device, including position and attitude data, environmental perception data, and the device's own status perception data. The comprehensive judgment includes: whether there are any abnormalities or safety hazards in the equipment itself; whether the interlocking conditions of the equipment itself are met; whether the interlocking conditions of the upstream and downstream related equipment are met; if an abnormality is detected, an alarm message will be immediately displayed and the execution of the current task will be terminated; if all the checks are normal, the corresponding start or stop command will be issued according to the start-up reverse order or stop order in the workflow.
[0010] Furthermore, the step of controlling each device to complete the entire process according to the optimal work flow specifically includes: According to the set collaborative control workflow sequence, the system sequentially performs start or stop operations on each device within the workflow. If the current device is successfully started or is already in operation, it automatically jumps to the next device in the workflow to continue performing material picking or feeding tasks until the collaborative operation of all devices in the entire process is completed.
[0011] Furthermore, the operation log includes a structured operation log and a fault alarm log. The content of the operation log includes: process start / end timestamp, energy consumption curve, and bulk material transportation volume curve.
[0012] Compared with the prior art, the present invention has the following advantages: This invention provides an integrated collaborative control method for heterogeneous equipment in port operations throughout the entire process. It collects real-time operational data from port equipment and constructs equipment information models and standardized data models. It acquires data information for the entire operation process, initially filtering workflows based on the start and end point locations. It then assesses the current workflow and determines the optimal operation process. Following the optimal process and equipment startup sequence, it sequentially performs self-checks. It controls each piece of equipment to complete the entire operation according to the optimal process. Finally, it generates an operation log based on the completion status of the entire operation, enabling full-cycle traceability of the entire process. This invention breaks down barriers between equipment, enabling unified management and collaborative control of these heterogeneous devices. This integrated collaborative control improves overall port operational efficiency, achieves seamless connection and collaborative operation between equipment, thereby reducing waiting time, enhancing operational accuracy, lowering operating costs, and optimizing resource allocation.

The acquired data undergoes communication protocol conversion, data preprocessing, and analysis in the heterogeneous equipment edge computer, and a unified equipment information model and standardized data model are built upon this foundation.

In a preferred embodiment of the present invention, the data information of the entire job process includes the start position, end position, target position and related equipment details of the job. Based on the data information of the entire job process, the equipment information model and the standardized data model are called to initially screen the workflow.
