[0019] Figure 2 A schematic diagram of the structure of a computer system suitable for implementing an electronic device according to an embodiment of the present application is shown. DETAILED DESCRIPTION

[0020] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art.

[0021] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner.In the following description, many specific details are provided so as to provide a full understanding of the embodiments of the present application. However, it will be appreciated by those skilled in the art that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps etc. can be adopted. In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0022] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0023] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[0024] The following is a detailed description of the implementation details of the technical solution of the embodiment of the present application:

[0025] First, the unmanned loading program is switched to the automatic position, and the program begins to determine whether there is a process running. If no process is running, the program finds out the warehouse number that needs to be added and the process and reclaimer that need to be used based on the warehouse location information and equipment process information of the sintering raw material warehouse, starts the process and reclaimer, moves the unloading trolley to the target warehouse number, and starts the loading operation until the loading is completed.

[0026] Furthermore, after the unloading trolley completes the loading operation, the silo number that needs to be added in the same area is found according to the position of the unloading trolley. After the current silo is full, the unloading trolley moves to other silos that need to be added in the same area to continue adding materials.

[0027] Furthermore, after the silo in the same area is full, the silo number of the silo in other areas that needs to be added is determined, the reclaimer stops reclaiming, and the raw material flow is interrupted on the belt conveyor. When the interrupted flow reaches the unloading trolley, the unloading trolley switches operation and moves to the target silo in other areas to continue adding materials.

[0028] Furthermore, some embodiments include multiple unloading carts. When the silo corresponding to one unloading cart is full, the other unloading carts are determined to correspond to silos that need refilling. The unloading carts move to the target silo, initiating process switching. The two unloading cart processes run simultaneously, and the reclaimer begins reclaiming material. In some embodiments, one reclaimer reclaims material, and two unloading carts receive material, each receiving material from a different location. When one unloading cart has finished receiving material from the conveyor belt, the conveyor belt switches its path, and another unloading cart receives material from a different location.

[0029] Furthermore, when all the silos are full, the reclaimer stops reclaiming and the process stops after 3 minutes. After the process stops, a new cycle is started, that is, the current state of the feeding system is obtained.

[0030] In order to make those skilled in the art better understand this application, Figure 1 A brief description of this application is given.

[0031] According to some embodiments, the loading system includes a discharge trolley for loading material to a location to be loaded, and the method includes:

[0032] Step 101: Obtain the current area of ​​the unloading vehicle, and obtain all target positions corresponding to the current area based on the current area;

[0033] Step 102, obtaining the positions to be added that need to be added among all target positions;

[0034] Step 103: Control the unloading trolley to add material to the position to be added.

[0035] Based on the above embodiment, in step 101, a discharge cart is set up in each area, that is, a discharge cart is responsible for the material delivery task of the entire area. After the discharge cart completes the material delivery task in its area, it can change areas to help other discharge carts deliver materials. The target location indicates when the location where material is needed is short of material and when the location where material is needed is full of material. In some embodiments of the present application, the target location is a silo that needs to be added. In other embodiments, the target location may not be a silo.

[0036] In step 102, the locations of all silos that need to be refilled in the area that the unloading vehicle is responsible for are obtained.

[0037] In step 103, the unloading trolley is controlled to travel to the silo along the shortest and most time-saving route, and the silo is charged with materials until the charging is completed.

[0038] According to some embodiments, in step 101, before obtaining the current area of ​​the unloading vehicle and obtaining all target positions corresponding to the current area based on the current area, the method further includes:

[0039] Step 91, obtaining the current state of the feeding system;

[0040] Step 92: If the current state of the feeding system is the process end state, all target positions of all areas are obtained;

[0041] Step 93, judging whether there is a position to be added that needs to be added based on all target positions in all areas;

[0042] Step 94: If there is a position to be charged that needs to be charged, control the unloading trolley to move to the position to be charged for charging.

[0043] Based on the above embodiment, in step 91, the current state of the feeding system is obtained to determine whether there is a process running.

[0044] In step 92, if no process is running, that is, the process ends, all silo information in all areas is obtained.

[0045] In step 93, based on the location information of the sintering raw material bin and the equipment process information, it is determined whether there is a bin that needs to be charged.

[0046] In step 94, if there is a silo that needs to be added, find out the silo number that needs to be added, the process that needs to be used, and information such as the reclaimer and unloading trolley, and control the unloading trolley to move to the silo that needs to be added to add material until the addition is completed.

[0047] Furthermore, in step 92, if the current state of the feeding system is the process end state, then obtaining all target positions of all areas, the method further includes:

[0048] If the current state of the feeding system is the process progress state, the process proceeds to step 101, wherein the current area of ​​the unloading vehicle is obtained, and all target positions corresponding to the current area are obtained based on the current area.

[0049] Furthermore, in step 94, if there is a position to be charged that needs to be charged, the unloading trolley is controlled to move to the position to be charged to charge, and the method further includes:

[0050] If there is no silo that needs to be added, the process ends.

[0051] According to some embodiments, in step 94, if there is a position to be charged that needs to be charged, the unloading trolley is controlled to move to the position to be charged to charge, and the method further includes:

[0052] Step 941, obtaining the current loading amount on the unloading trolley and the required amount of the position to be loaded;

[0053] Step 942: Compare the current loading amount with the required amount. If the current loading amount is greater than or equal to the required amount, control the unloading trolley to move to the position to be loaded for loading.

[0054] Based on the above embodiment, in step 941, if there is a silo that needs to be refilled, the amount of raw materials currently loaded on the unloading trolley is first obtained, and then the required amount of the silo is obtained.

[0055] In step 942, the amount of raw materials currently loaded on the unloading trolley is compared with the required amount of the silo. If the amount of raw materials currently loaded on the unloading trolley is greater than or equal to the required amount of the silo, the unloading trolley is controlled to move to the silo for adding materials.

[0056] Furthermore, the loading system further includes a reclaimer for reclaiming material to an initial position, and a conveyor belt for receiving material from the reclaimer and transferring the material from the reclaimer to a discharge trolley. In step 942, after comparing the current material load with the required material load, the method further includes:

[0057] Step 943: If the current material load is less than the required amount, control the reclaimer to reclaim the material, and after the reclaim is completed, control the reclaimer to transport the material to one end of the belt conveyor;

[0058] Step 944: After controlling the unloading trolley to move to the other end of the belt conveyor, control the belt conveyor to transfer the material from the reclaimer to the unloading trolley;

[0059] Step 945: After the unloading trolley is loaded, the unloading trolley is controlled to move to the position to be loaded for loading.

[0060] Based on the above embodiment, if the amount of raw materials currently loaded on the unloading trolley is less than the demand of the silo, the material reclaimer is controlled to reclaim the materials first. After the material reclaimer completes the material reclaiming, the material reclaimer is controlled to transport the materials to one end of the belt conveyor. Then, the unloading trolley is controlled to move to the other end of the belt conveyor, and the belt conveyor is controlled to start working to transfer the materials from the reclaimer to the unloading trolley. The unloading trolley is loaded until the amount of raw materials currently loaded on the unloading trolley is greater than or equal to the demand of the silo. After the unloading trolley is loaded, the unloading trolley is controlled to move to the silo that needs to be added to add materials.

[0061] Furthermore, in step 103, after controlling the unloading trolley to add material to the position to be added, the method further includes:

[0062] Step 1031, determining whether there are any silos that need to be refilled at all target locations in the current area;

[0063] Step 1032: If there are no silos that need to be added at all target locations in the current area, then determine whether there are silos that need to be added at all target locations in other areas.

[0064] Step 1033: If there are no silos that need to be refilled at all target locations in other areas, the process ends.

[0065] Furthermore, in step 1032, if no silo needs to be added at any target location in the current area, it is determined whether any silo needs to be added at any target location in other areas. The method further includes:

[0066] If there is a silo that needs to be added among all the target positions in the current area, the unloading trolley is controlled to move to the silo that needs to be added to add material.

[0067] Furthermore, if there is no position to be added at all target positions in other areas, then the process is terminated, and the method further includes:

[0068] If there is a position to be charged among all target positions in other areas, the unloading trolley is controlled to move to the position to be charged for charging.

[0069] Furthermore, after the process ends, the process re-enters step 91 to obtain the current state of the feeding system.
