Technical Field

[0001] This invention relates to the field of industrial lifting, transportation and scheduling technology, and in particular to an intelligent hoisting track scheduling system and method for heavy equipment in multi-story industrial plants. Background Technology

[0002] In modern manufacturing, multi-story industrial plants are widely used due to their advantages such as saving land. These plants typically house heavy equipment such as large injection molding machines, presses, and machine tools. The installation, maintenance, replacement, or adjustment of the process layout of this equipment requires hoisting and relocation.

[0003] Currently, traditional solutions mainly rely on: 1. Fixed bridge cranes: These require installation on each floor, resulting in huge investments. Furthermore, because each crane can only operate within a fixed track range, continuous transport across floors and areas is impossible. Moving equipment to different floors is cumbersome, requiring multiple transfers and is extremely inefficient. 2. Truck cranes or large forklifts: These require wide transport aisles and huge operating space, placing high demands on the load-bearing capacity and spatial structure of the factory building. Within multi-story factory buildings, their mobility is severely limited, and they present problems such as high safety risks, poor operational precision, and significant damage to the ground. 3. Manually operated simple gantry cranes / chain hoists: These rely entirely on manpower, resulting in high labor intensity, low efficiency, poor positioning accuracy, and significant safety hazards.

[0004] Therefore, existing technologies that use fixed bridge cranes, truck cranes or large forklifts, simple gantry cranes / chain hoists for lifting and transportation are cumbersome, have high safety risks, poor operational accuracy, rely on manpower, and have poor positioning accuracy, resulting in low efficiency.

Specifically, the intelligent hoisting track scheduling method is applied to the scheduling controller, and the intelligent hoisting track scheduling system 100 is applied to the hoisting and transfer of heavy equipment in multi-story industrial plants. The track network is set in the top and side spaces of the multi-story industrial plant, without occupying ground space, thus greatly freeing up the effective usable area of ​​the plant.

The sensing component 26 includes at least one of a lidar, an ultrasonic sensor, and a collision avoidance radar.

[0035] like Figure 4 As shown, the intelligent hoisting track scheduling method includes the following steps S110-S140.

[0036] S110. When a hoisting task is received, obtain the task information corresponding to the hoisting task, and obtain the global traffic status and three-dimensional digital map.

[0037] In this embodiment, as Figures 1 to 4 As shown, the task information includes equipment data and location data; the equipment data may include equipment weight or dimensions, etc.; the location data may include three-dimensional coordinate data such as start-point coordinates and end-point coordinates; the global traffic status is the real-time traffic route information and hoisting device 20 data of at least one of the hoisting devices 20, and the real-time traffic route information is the operating route information of at least one of the hoisting devices 20; the hoisting device 20 data may include hoisting position and hoisting status, the hoisting position is the current position coordinates of the hoisting device 20; the hoisting status is whether the hoisting device 20 is idle, which may include idle status and busy status; the three-dimensional digital map is a BIM model of a multi-story industrial plant.

[0038] S120. Select at least one of the hoisting devices to obtain a target hoisting device based on the task information and the global traffic status.

[0039] In this embodiment, after obtaining the task information and the global traffic status, at least one hoisting device 20 can be selected as a target hoisting device 20 based on the task information and the global traffic status. The number of target hoisting devices 20 can be one or more.

[0040] In one embodiment, selecting at least one of the lifting devices to obtain a target lifting device based on the task information and the global traffic status includes: Determine the starting and ending coordinates of the target device based on the task information; The hoisting position and hoisting status of at least one of the hoisting devices are obtained at the current moment based on the global traffic status. The target lifting device is obtained by selecting at least one of the lifting devices based on the starting point coordinates, the ending point coordinates, the lifting position, and the lifting status.

[0041] In this embodiment, as Figures 1 to 4 As shown, the starting coordinates and ending coordinates of the target device are obtained from the task information, and the hoisting position and hoisting status of at least one hoisting device 20 at the current time are obtained according to the global traffic status.

[0042] The step of selecting at least one of the lifting devices 20 based on the starting point coordinates, the ending point coordinates, the lifting position, and the lifting status to obtain the target lifting device 20 includes: using the lifting status to obtain idle lifting devices 20 from at least one of the lifting devices 20 as a set of idle lifting devices 20; obtaining the lifting position corresponding to the set of idle lifting devices 20, and using the starting point coordinates, the ending point coordinates, and the lifting position to select from the set of idle lifting devices 20 to obtain the target lifting device 20.

[0043] S130. Based on the task information, the three-dimensional digital map, and the global traffic status, the optimal path is planned.

[0044] In this embodiment, as Figures 1 to 4 As shown, the step of planning the optimal path based on the task information, the three-dimensional digital map, and the global traffic status includes: eliminating idle paths according to the three-dimensional digital map and the global traffic status, and then planning the optimal path in the idle paths according to the starting coordinates and ending coordinates in the task.

[0045] S140. The target equipment is hoisted using the target hoisting device, and the target hoisting device is controlled to run on the track network using the optimal path.

[0046] In this embodiment, after obtaining the target hoisting device 20 and the optimal path, the target equipment can be hoisted using the target hoisting device 20, and the target hoisting device 20 can be controlled to run on the track network using the optimal path.

[0047] In one embodiment, the step of using the target hoisting device to hoist the target equipment and using the optimal path to control the operation of the target hoisting device on the track network includes: When the optimal path crosses floors, the transfer platform of the target floor is locked, the target equipment is hoisted using the target hoisting device, and the target hoisting device is controlled to run between the main track, the lifting track, and the transfer platform.

[0048] In this embodiment, as Figures 1 to 4 As shown, the optimal path may include a starting floor, a target floor, and a route; when the starting floor and the target floor are the same, the optimal path does not cross floors; when the starting floor and the target floor are different, the optimal path crosses floors.

[0049] When the optimal path crosses floors, the transfer platform 13 of the target floor is locked using the floor safety door lock mechanism 15, the target equipment is hoisted using the target hoisting device 20, the transfer platform 13 of the target floor is moved to the starting floor via the lifting rail 12, and the target hoisting device 20 is controlled to run between the main rail 11, the lifting rail 12 and the transfer platform 13 according to the running route, so as to transport the target hoisting device 20 to the endpoint coordinates.

[0050] When the optimal path does not cross floors, the target hoisting device 20 is used to hoist the target equipment, and the target hoisting device 20 is controlled to run on the main track 11 according to the running route to transport the target hoisting device 20 to the endpoint coordinates.

[0051] Furthermore, the target hoisting device 20 operates autonomously along the optimal path, and the hoisting control component of the target hoisting device 20 combines the optimal path and the data from the sensing component 26 to perform local real-time obstacle avoidance and precise positioning.

[0052] Furthermore, the scheduling controller monitors the operation of all hoisting devices 20 in real time and can dynamically adjust the path to avoid potential conflicts until the hoisting task is completed.

[0053] Furthermore, when the sensing component 26 detects an unforeseen obstacle on the optimal path, the target hoisting device 20 will immediately stop and alarm the scheduling controller, which will then replan the path or wait for manual intervention.

[0054] Furthermore, this scheduling method supports the parallel processing of multiple hoisting tasks. The scheduling controller achieves coordinated scheduling of multiple intelligent hoisting devices 20 through time window planning and priority management, avoiding path conflicts and resource deadlocks.

[0055] Furthermore, in a real-world scheduling scenario, the operator issues the hoisting task through the HMI interface: "Move a 10-ton piece of equipment from point A (starting coordinates X1, Y1, Z1) on the first floor to point B (ending coordinates X3, Y3, Z3) on the third floor." Upon receiving the hoisting task, the operator obtains the task information corresponding to the hoisting task, as well as the global traffic status and the 3D digital map. Based on the task information and the global traffic status, at least one hoisting device 20 is selected to obtain the target hoisting device 20. For example, intelligent hoisting device 20#01, located on the first floor and available, is selected as the target hoisting device 20, and the hoisting task is then assigned to the target hoisting device 20.

[0056] Based on the task information, the 3D digital map, and the global traffic status, the optimal path is planned for the target hoisting device 20, namely, the planned path for the target hoisting device 20#01: from point A on the first floor, through the first-floor transfer platform 13, the lifting track 12 (to the third floor), and then through the third-floor transfer platform 13 to point B on the third floor. Specifically, the optimal path can be transmitted to the target hoisting device 20#01 via a wireless AP (Access Point).

[0057] The target device is fixed to the target hoisting device 20, and the target hoisting device 20 is controlled to run on the track network using the optimal path. Specifically, after receiving the optimal path, the target hoisting device 20#01 starts autonomously and moves towards the first-floor transfer platform 13 using the sensing component 26 and positioning component 25 on the target hoisting device 20. During the journey, the sensing component 26 on the target hoisting device 20 continuously scans ahead, and the RFID reader in the positioning component 25 and the RFID tags arranged at key nodes on the main track 11 continuously identify the main track 11 to ensure path safety and accuracy. After reaching the first-floor transfer platform 13, the scheduling controller confirms the lifting. Track 12 is idle, and the floor safety door lock mechanism 15 is unlocked; the target hoisting device 20#01 smoothly enters the lifting track 12; the lifting track 12 starts, safely lifting the target hoisting device 20#01 and its target equipment to the third floor; after reaching the third floor, the target hoisting device 20#01 exits the lifting track 12 and enters the network structure of the main track 11 on the third floor, and finally runs precisely above point B; at the same time, through precise ultra-wideband positioning tags, the target hoisting device 20#01 lowers the target equipment to the endpoint coordinates with an error of less than ±10mm; the hoisting task is completed, the target hoisting device 20#01 reports to the dispatch controller and enters an idle state. Meanwhile, the monitoring interface of the dispatch controller displays the position and status of all hoisting devices 20 in real time; if another hoisting task is being executed simultaneously, it will automatically calculate and allow the two target hoisting devices 20 to pass through intersections in sequence to avoid collisions. Therefore, it integrates multiple safety protection measures, including global path collision avoidance, local real-time obstacle avoidance, overload protection, and electrical interlocks, to ensure the safety and reliability of the entire hoisting process.

[0058] In summary, the intelligent hoisting track scheduling method described in this embodiment of the invention is applied to the intelligent hoisting track scheduling system 100. The intelligent hoisting track scheduling system includes a track network, at least one hoisting device 20, and a scheduling controller. The scheduling controller is communicatively connected to the track network and at least one hoisting device 20. The hoisting device 20 is used to hoist a target device, and the scheduling controller controls each hoisting device 20 to operate on the track network. The intelligent hoisting track scheduling method includes: when a hoisting task is received, acquiring task information corresponding to the hoisting task, and acquiring global traffic status and a three-dimensional digital map; selecting at least one hoisting device 20 as a target hoisting device 20 based on the task information and the global traffic status; planning an optimal path based on the task information, the three-dimensional digital map, and the global traffic status; hoisting the target device using the target hoisting device 20 and controlling the target hoisting device 20 to operate on the track network using the optimal path. Therefore, the entire process from receiving tasks to operating target equipment is automated, significantly reducing manual intervention, improving efficiency, and lowering labor costs and the risk of human error. Furthermore, through the track network and intelligent scheduling, continuous and seamless transfer of heavy equipment in both horizontal and vertical directions is achieved, completely solving the problem of cross-floor hoisting. At the same time, the system is easy to expand, and tracks and hoisting devices can be added according to changes in the factory layout.
