[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.
[0045] In a first aspect, an embodiment of the present application provides a container truck dispatching method, which is applied to a target tower crane, and the target tower crane communicates with the container truck based on PC5 direct communication technology.
[0046] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the container truck dispatching method of the present application. Figure 1 As shown, the container truck scheduling method includes:
[0047] Step S10: issuing container loading and unloading tasks to a plurality of container trucks, so that the container trucks can perform response processing based on the container loading and unloading tasks.
[0048] Exemplarily, in the embodiments of the present application, the target tower crane refers to the equipment used to lift and move containers in the container yard or port; the container truck is a special truck for transporting containers, which is responsible for transporting containers in the port or warehouse; the container loading and unloading task refers to the specific task assigned to the container truck by the target tower crane, such as loading or unloading a container. The container truck can respond and confirm the received loading and unloading task to ensure that the task is correctly received and understood so as to carry out subsequent operations; PC5 is a direct communication technology with a short communication distance. It can realize direct communication between devices without relying on infrastructure such as base stations. In the embodiments of the present application, the PC5 direct communication technology can be used to realize fast and reliable data exchange between the container truck and the target tower crane to support the scheduling and execution of loading and unloading tasks.
[0049] It should be noted that in the embodiment of the present application, each target tower crane is taken as the center, and an RSU (Road Side Unit) terminal is installed on the target tower crane to publish loading and unloading tasks; an OBU (OnBoard Unit) terminal is installed on each container truck to receive loading and unloading tasks. The messages to be sent during the entire container truck scheduling process include task release messages, task response messages, and task confirmation messages, among which the task release and task confirmation messages are published by the RSU terminal (i.e., the target tower crane), and the task response message is published by the OBU terminal (i.e., the target container truck).
[0050] Specifically, after the target tower crane issues loading and unloading tasks to multiple container trucks, the container trucks can respond and process according to the received loading and unloading task information. The above direct task issuance and response mechanism can realize efficient container truck scheduling, and the target tower crane and container trucks communicate in real time through PC5 direct communication technology, which can quickly identify the status and location of each container truck, thereby dynamically adjusting task allocation and improving resource utilization.
[0051] Step S20: Acquire the number of target container trucks and the distance between the target container trucks and the target crane, wherein the target container trucks are the target container trucks that respond to the container loading and unloading task.
[0052] Exemplarily, in the embodiment of the present application, the target container truck refers to the container truck that responds to the container loading and unloading tasks, is responsible for transporting the container to the tower crane for loading and unloading operations, and is a key link in the container logistics chain; the quantity refers to the total number of container trucks that respond to the container loading and unloading tasks, and the distance refers to the distance between the target container truck and the target tower crane, which is used to evaluate the time and resource allocation for the target container truck to arrive at the target tower crane, helping to optimize scheduling and improve efficiency.
[0053] Specifically, PC5 communication technology can be used to obtain the number of target container trucks and the distance between them and the target tower crane in real time. That is, by mastering the number and distance of container trucks in real time, the loading and unloading tasks can be reasonably arranged, which significantly improves the efficiency, safety and flexibility of container loading and unloading operations and promotes the optimized operation of the entire port loading and unloading.
[0054] Step S30: Determine a first container truck from the target container trucks based on the number and the distance.
[0055] Exemplarily, in an embodiment of the present application, the first container truck refers to a container truck selected from the target container trucks that meets the conditions (such as the closest distance, idle state, etc.). The principle of proximity can be adopted to preferentially assign loading and unloading tasks to container trucks that are close to the target tower crane to improve overall operating efficiency.
[0056] Specifically, the number of all responding target container trucks can be determined, and the distance between the target container trucks and the target tower crane can be obtained; based on these data, an algorithm or decision rule (such as selecting the container truck with the closest distance) can be used to determine which truck is most suitable for performing the loading and unloading task. It should be noted that the above process can be automatically completed through the tower crane software.
[0057] Step S40: issuing task confirmation information to the first container truck to implement the scheduling of the container truck.
[0058] Exemplarily, in the embodiment of the present application, the task confirmation information refers to the task confirmation instruction or notification sent by the target tower crane to the selected first container truck, which is used to confirm that it is selected to perform a specific loading and unloading task, thereby avoiding the problem of task competition caused by multiple container trucks responding to the task at the same time. Specifically, after determining the first container truck, the target tower crane can instruct the first container truck to perform the corresponding loading and unloading operation by issuing the task confirmation information, thereby finally realizing the scheduling of the container truck.
[0059] This application uses PC5 direct communication technology to enable the target tower crane to communicate with the container truck, eliminating the dependence on base stations and 4G / 5G modules, and does not require the use of SIM cards, reducing the cost of scheduling. The target tower crane issues container loading and unloading tasks to multiple container trucks for the container trucks to respond and process based on the container loading and unloading tasks; obtains the number of target container trucks that respond to the container loading and unloading tasks and the distance between the target container truck and the target tower crane; determines the first container truck from the target container trucks based on the number and distance; issues task confirmation information to the first container truck to achieve scheduling of the container truck. The distributed scheduling system centered on the tower crane in this application has a higher risk resistance, and the failure of a single tower crane center will not affect the entire container truck scheduling work, which improves the flexibility and risk resistance of port container truck scheduling.
[0060] Further, in one embodiment, determining the first container truck from the target container trucks based on the number and the distance includes:
[0061] If it is detected that the number of target container trucks is greater than 1, determining a first container truck from the target container trucks based on the distance;
[0062] If it is detected that the number of target container trucks is equal to 1, the target container truck is used as the first container truck.
[0063] Exemplarily, in the embodiment of the present application, the first container truck refers to the container truck selected to perform the task, which will be responsible for a specific loading and unloading or transportation task to ensure efficient use of resources; Figure 2 As shown, if the number of target container trucks detected is greater than 1, it means that there are multiple responding container trucks. At this time, it is necessary to determine which truck will be the first container truck based on the distance between the target container and the target tower crane; if only one target container truck is detected, it can be directly selected as the first container truck, thereby speeding up the dispatching process of container trucks.
[0064] Further, in one embodiment, determining the first container truck from the target container trucks based on the distance includes:
[0065] Sort all distances in ascending order, and take the minimum distance as the target distance;
[0066] The target container truck corresponding to the target distance is taken as the first container truck.
[0067] Exemplarily, in an embodiment of the present application, the distances from all container trucks to the target tower crane can be sorted from small to large to find the target container truck closest to the target tower crane; the minimum distance is taken as the target distance, and the target container truck corresponding to the target distance is taken as the first container truck to select the optimal container truck for loading and unloading tasks, thereby reducing waiting time and driving time and ensuring a quick response.
[0068] Furthermore, in one embodiment, the container truck performs response processing based on the container loading and unloading task, including:
[0069] For each target container truck, when the target container truck receives container loading and unloading tasks issued by multiple target cranes at the same time, the current task status of the vehicle is determined;
[0070] If the vehicle is in the task execution state or in the task confirmation state, it will not respond to the container loading and unloading task;
[0071] If the vehicle is not in the task execution state and is not in the task confirmation state, a response is made to the container loading and unloading task.
[0072] Exemplarily, in an embodiment of the present application, the current task status is used to determine whether the target container truck is currently executing a task or confirming a task. Whether a new task can be accepted can be determined by determining the status of the container truck; the task execution status means that the target container truck is performing a certain loading and unloading task. In this state, the container truck does not accept new tasks to avoid task conflicts; the task confirmation status means that the target container truck is waiting for confirmation from the target tower crane. In this state, the container truck also does not accept new tasks to ensure the integrity of the confirmation process.
[0073] Specifically, when the target container truck receives loading and unloading tasks from multiple cranes at the same time, refer to Figure 3 As shown, the current task status of the target container truck can be determined first; if the target container truck is in the task execution state or task confirmation state, it means that the container truck is loading and unloading tasks or waiting for the target crane to confirm the task, and it will not respond to the new task; if the container truck is not in these two states, it means that the container truck is idle, and it will respond to the new task. It can be understood that the orderly execution of tasks can be ensured and task conflicts can be avoided through the state judgment mechanism.
[0074] Furthermore, in one embodiment, before the step of obtaining the number of target container trucks, the method further includes:
[0075] If the target container truck is not detected within the preset time, the container loading and unloading task will be reissued.
[0076] Exemplarily, in an embodiment of the present application, the preset duration refers to the maximum waiting time for the target tower crane to receive a response from a container truck, which can be determined based on actual needs and is not limited here; specifically, when the target tower crane has been waiting for the preset period of time, if there is still no container truck to feedback a response information to it, that is, when the container truck fails to respond in time, the target tower crane will automatically reissue the task, thereby ensuring that the loading and unloading work will not be delayed due to the lack of a container truck, thereby improving the efficiency and flexibility of the container loading and unloading process.
[0077] In a second aspect, an embodiment of the present application further provides a container truck dispatching system, which is applied to a target tower crane, and the target tower crane communicates with the container truck based on PC5 direct communication technology.
[0078] In one embodiment, referring to Figure 4 , Figure 4 This is a functional module diagram of an embodiment of the container truck dispatching system of this application. Figure 4 As shown, the container truck dispatching system includes:
[0079] A first processing module, which is used to issue container loading and unloading tasks to a plurality of container trucks, so that the container trucks can perform response processing based on the container loading and unloading tasks;
[0080] A second processing module, which is used to obtain the number of target container trucks and the distance between the target container trucks and the target tower crane, wherein the target container trucks are the target container trucks that respond to the container loading and unloading task;
[0081] a third processing module for determining a first container truck based on the number and the distance;
[0082] The fourth processing module is used to issue task confirmation information to the first container truck to realize the scheduling of the container truck.
[0083] Furthermore, in one embodiment, the third processing module is specifically used for:
[0084] If the number of target container trucks detected is greater than 1, determining the first container truck based on the distance;
[0085] If it is detected that the number of target container trucks is equal to 1, the target container truck is used as the first container truck.
[0086] Furthermore, in one embodiment, the third processing module is further configured to:
[0087] Sort all distances in ascending order, and take the minimum distance as the target distance;
[0088] The target container truck corresponding to the target distance is taken as the first container truck.
[0089] Furthermore, in one embodiment, the second processing module is specifically configured to:
[0090] For each target container truck, when the target container truck receives container loading and unloading tasks issued by multiple target cranes at the same time, the current task status of the vehicle is determined;
[0091] If the vehicle is in the task execution state or in the task confirmation state, it will not respond to the container loading and unloading task;
[0092] If the vehicle is not in the task execution state and is not in the task confirmation state, a response is made to the container loading and unloading task.
[0093] Furthermore, in one embodiment, the second processing module is further configured to:
[0094] If the target container truck is not detected within the preset time, the container loading and unloading task will be reissued.
[0095] This application uses PC5 direct communication technology to enable the target tower crane to communicate with the container truck, eliminating the dependence on base stations and 4G / 5G modules, and does not require the use of SIM cards, reducing the cost of scheduling. The target tower crane issues container loading and unloading tasks to multiple container trucks for the container trucks to respond and process based on the container loading and unloading tasks; obtains the number of target container trucks that respond to the container loading and unloading tasks and the distance between the target container truck and the target tower crane; determines the first container truck from the target container trucks based on the number and distance; issues task confirmation information to the first container truck to achieve scheduling of the container truck. The distributed scheduling system centered on the tower crane in this application has a higher risk resistance, and the failure of a single tower crane center will not affect the entire container truck scheduling work, which improves the flexibility and risk resistance of port container truck scheduling.
