Description

Technical Field

[0001] This application relates to the field of logistics automation control technology, and in particular to a method, apparatus, computer equipment, and storage medium for returning equipment to its empty state. Background Technology

[0002] With the expansion of production scale, in order to ensure the efficiency of material transportation, factories have gradually adopted transportation vehicles to transport materials. Using transportation vehicles for material transportation has advantages such as simple construction, flexible routes, safety and reliability, and high mobility and flexibility. However, the process of transporting materials by means of transportation vehicles also involves the task of returning empty equipment to its original location.

[0003] In traditional technology, during the return mission of air-to-ground equipment using transportation vehicles, the transportation vehicle dispatching equipment typically receives the return mission instruction and dispatches the empty equipment to the logistics area to await the next mission. However, the logistics area usually involves both transportation vehicles and manual labor, and the transportation vehicles and manual operations often interfere with each other during the return mission, resulting in very low efficiency in completing the mission.

[0061] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0062] It should be noted that the terms "comprising," "including," "having," and any variations thereof, as used in this application, are intended to cover non-exclusive inclusion. For example, a process, method, product, or apparatus that includes a series of steps or means is not necessarily limited to the steps that are clearly listed, but may also include other steps or means that are not clearly listed or that are inherent to such process, method, product, or apparatus. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0063] Furthermore, the terms "first," "second," etc., used in this application are for naming purposes to distinguish similar objects, but these objects themselves are not limited by these terms. It should be understood that these terms may be used interchangeably where appropriate without departing from the scope of this application. For example, a "first return-to-empty instruction" may be described as a "second return-to-empty instruction," and similarly, a "second return-to-empty instruction" may be described as a "first return-to-empty instruction."

[0064] The device return method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, server 102 can obtain real-time information on the material consumption of equipment loaded on the production line. Forklift terminal 104 communicates with server 102 via a network, and transport vehicle 106 also communicates with server 102 via a network. A data storage system can store the data that server 102 needs to process. The data storage system can be integrated onto server 102 or hosted on the cloud or other network servers.

[0065] After the materials loaded on the equipment are consumed, the server 102 generates a first empty return instruction corresponding to the empty equipment. Then, based on the first empty return instruction, it obtains the logistics gate card information corresponding to the empty equipment and determines whether there is a usable empty card. Then, it reserves a target empty card among the empty card, and obtains card reservation information. If it is determined based on the card reservation information that there are enough target empty card, a first dispatch instruction is generated and then sent to the transport vehicle 106 carrying the empty equipment to instruct the transport vehicle 106 to transport the empty equipment to the target empty card.

[0066] The vehicle-mounted terminal 104 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can be smart vehicle-mounted devices, etc. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc. The server 102 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0067] In one embodiment, the server of this application integrates a MOM (Manufacturing Operations Management), a LES (Logistics Execution System), and an AGV system. The MOM system acquires information on the consumption of materials loaded on the equipment and, upon depletion of the materials, sends a signal to the LES system. The LES system, upon receiving the depletion signal, generates a first empty return instruction corresponding to the empty equipment and sends it to the AGV system. The AGV system, upon receiving the first empty return instruction, retrieves the logistics gate position information corresponding to the empty equipment based on the instruction, determines available gate positions, and then reserves target available gate positions to obtain gate reservation information. If sufficient target available gate positions are determined based on the gate reservation information, a first scheduling instruction is generated and sent to the transport vehicle carrying the empty equipment. Upon receiving the first scheduling instruction, the transport vehicle transports the empty equipment to the target available gate position according to the instructions.

[0068] In one embodiment, such as Figure 2 As shown, a method for returning an instrument to its empty state is provided, which can be applied to... Figure 1 Taking the server in the example, the following steps are included:

[0069] Step 202: After the materials loaded in the device are consumed, generate the first empty return command corresponding to the empty device.

[0070] Among them, the empty return instruction is an instruction to return empty equipment from the production line to the loading area. The first empty return instruction can be an instruction to return empty equipment from the production line to the logistics gate.

[0071] Specifically, the equipment is loaded with materials for production on the production line. After the materials loaded in the equipment are consumed, the server generates a first empty return command corresponding to the empty equipment where the loaded materials have been consumed.

[0072] In one embodiment, when the materials loaded in the appliance are consumed and there are no materials in the material buffer, the server generates a first empty appliance return instruction.

[0073] Step 204: Obtain the logistics gate position information corresponding to the empty equipment according to the first empty return instruction, and determine the available position according to the logistics gate position information.

[0074] Among them, "idle card slot" refers to a logistics gate card slot that is in an idle state.

[0075] Specifically, after the server generates the first empty return instruction, it obtains the logistics gate card position information corresponding to the empty device based on the first empty return instruction, and then determines the available empty card position based on the logistics gate card position information.

[0076] In one embodiment, obtaining the logistics gate slot information corresponding to the empty device according to the first empty return instruction, and determining the available slot according to the logistics gate slot information includes: determining the logistics gate slot corresponding to the empty device according to the first empty return instruction, obtaining the logistics gate slot information of the logistics gate slot corresponding to the empty device, the logistics gate slot information including the usage status of the logistics gate slot, including the occupied status, the reserved status or the idle status, and taking the logistics gate slot with the usage status of idle status as the available slot.

[0077] Specifically, the server pre-sets the correspondence information between equipment and logistics gate slots. After generating the first empty return command, the server can determine the logistics gate slot corresponding to the empty equipment based on the pre-set correspondence information, and then obtain the logistics gate slot information corresponding to the empty equipment. The logistics gate slot information includes the usage status of the logistics gate slot, which includes occupied, reserved, or idle status. A logistics gate slot in the occupied status indicates that work is currently being performed in that slot; a logistics gate slot in the reserved status indicates that the slot has been reserved and work will begin soon; a logistics gate slot in the idle status indicates that work is neither currently being performed nor about to begin. The server can then use logistics gate slots in the idle status as available idle slots. In one embodiment, the logistics gate slot information also includes the location and number of logistics gate slots corresponding to the empty equipment.

[0078] In this embodiment, the server determines the logistics gate position corresponding to the empty equipment according to the first empty return instruction, and obtains the logistics gate position information of the logistics gate position corresponding to the empty equipment. The logistics gate position information includes the usage status of the logistics gate position, including occupied status, reserved status, or idle status. Then, the logistics gate position with the usage status of idle status is regarded as an idle position, which can accurately and quickly return the empty equipment from the production line to its corresponding logistics gate position, thereby improving the return efficiency.

[0079] Step 206: Reserve the target vacant card slot from the available card slots to obtain card slot reservation information.

[0080] Among them, the target available card slot refers to the card slot selected from the available card slots, and the card slot reservation information is the information of the reserved available card slot.

[0081] Specifically, after the server determines the available vacant card slots, it selects a target vacant card slot from the available slots and reserves it, so that empty equipment can be returned from the production line to the vacant logistics gate card slot, thereby obtaining card slot reservation information. In one embodiment, the card slot reservation information may include the number and location information of the reserved vacant card slots, and the location information of the vacant card slots may be the card slot number.

[0082] Step 208: If it is determined that there are enough free target card slots based on the card slot reservation information, then generate the first scheduling instruction.

[0083] Among them, the dispatch instruction is the instruction to dispatch the transportation vehicle. The first dispatch instruction is the instruction to direct the transportation vehicle to the target available parking space.

[0084] Specifically, after receiving the card slot reservation information, the server can determine whether the number of target available card slots can meet the number of empty devices that need to be returned. If the number of target available card slots can meet the number of empty devices that need to be returned, a first scheduling instruction is generated. It can be understood that if the number of target available card slots cannot meet the number of empty devices that need to be returned, a second scheduling instruction is generated.

[0085] Step 210: Send the first dispatch instruction to the transport vehicle carrying the empty vehicle to instruct the transport vehicle to transport the empty vehicle to the target available parking space.

[0086] The transportation vehicle can be an AGV (Automated Guided Vehicle) or other transportation robots.

[0087] Specifically, the server sends the first scheduling instruction to the transport vehicle carrying the empty equipment. After receiving the first scheduling instruction, the transport vehicle transports the empty equipment from the production line to the target idle slot according to the instructions of the first scheduling instruction.

[0088] In the aforementioned method for returning empty equipment, a first return command corresponding to the empty equipment is generated after the materials loaded on the equipment are consumed. Based on this command, the logistics gate position information corresponding to the empty equipment is obtained. Then, an available gate position is determined based on this information. This allows for the reservation of a target available gate position and the acquisition of reservation information. If the reservation information indicates that there are sufficient target available gate positions, a first dispatch command is generated and sent to the transport vehicle carrying the empty equipment, instructing it to transport the empty equipment to the target available gate position. By reserving target available gate positions for the return task, interference with manual operations can be avoided, thereby improving return efficiency.

[0089] In one embodiment, if it is determined based on the card slot reservation information that there are insufficient target empty card slots, a second scheduling instruction is generated; the second scheduling instruction is sent to the transport vehicle carrying the empty equipment to instruct the transport vehicle to transport the empty equipment to the empty equipment buffer area.

[0090] The second dispatch instruction is an instruction to direct the transport vehicle to the empty vehicle buffer area.

[0091] Specifically, after receiving the slot reservation information, the server can determine whether the number of target available slots can meet the number of empty equipment that needs to be returned. If the number of target available slots cannot meet the number of empty equipment that needs to be returned, a second scheduling instruction is generated. This second scheduling instruction is then sent to the transport vehicle carrying the empty equipment. Upon receiving the second scheduling instruction, the transport vehicle transports the empty equipment from the production line to the empty equipment buffer area according to the instructions.

[0092] In this embodiment, when it is determined that there are not enough target empty card slots based on the card slot reservation information, a second scheduling instruction is generated and sent to the transport vehicle carrying empty equipment. Then, according to the second scheduling instruction, the transport vehicle is instructed to transport the empty equipment to the empty equipment buffer area. When the predetermined target empty card slots cannot meet the return empty equipment demand, the empty equipment generated on the production line can be diverted to the empty equipment buffer area to prevent congestion at the logistics gate card slots and thus improve the return empty efficiency.

[0093] In one embodiment, after the material loaded on the appliance is consumed, a first empty appliance return instruction is generated, including generating the first empty appliance return instruction when the material loaded on the appliance is consumed and there is no material in the material buffer. The appliance return method further includes generating a second empty appliance return instruction when the material loaded on the appliance is consumed and there is material in the material buffer, generating a third scheduling instruction based on the second empty appliance return instruction, and sending the third scheduling instruction to the transport vehicle carrying the empty appliance to instruct the transport vehicle to transport the empty appliance to the material buffer.

[0094] Among them, the second empty return instruction is an instruction to return empty equipment from the production line to the material buffer area, and the third dispatch instruction is an instruction to instruct the transport vehicle to go to the material buffer area.

[0095] Specifically, when the material loaded in the appliance is consumed and there is material in the material buffer, the server generates a second empty return instruction corresponding to the empty appliance, which returns the empty appliance from the production line to the material buffer. Based on the second empty return instruction, the server generates a third scheduling instruction that instructs the transport vehicle to go to the material buffer and sends the third scheduling instruction to the transport vehicle carrying the empty appliance. After receiving the third scheduling instruction, the transport vehicle transports the empty appliance from the production line to the material buffer to load material according to the instructions of the third scheduling instruction. After the material is loaded, it continues to be used for production on the production line until the material loaded in the appliance is consumed and there is no material in the material buffer. At this point, the server generates a first empty return instruction corresponding to the empty appliance.

[0096] In this embodiment, when the material loaded on the appliance is consumed and there is material in the material buffer area, a second empty return instruction corresponding to the empty appliance is generated. Then, a third scheduling instruction is generated based on the second empty return instruction and sent to the transport vehicle carrying the empty appliance to instruct the transport vehicle to transport the empty appliance to the material buffer area. In this way, if there is still material in the material buffer area, the transport vehicle carrying the empty appliance will not go to the logistics gate, avoiding logistics gate blockage and congestion, thereby improving the empty return efficiency.

[0097] In one embodiment, the above-mentioned empty equipment return method further includes receiving an arrival signal sent by the transport vehicle when the transport vehicle arrives at the target empty parking space, and forwarding the arrival signal to the on-board terminal of the forklift. The arrival signal is used to instruct the forklift to go to the target empty parking space to load the empty equipment unloaded to the target empty parking space, and transport the empty equipment to the empty equipment centralized storage area for transport by transport vehicles.

[0098] The arrival signal is a signal issued by the means of transport confirming that it has arrived at the designated target transportation location.

[0099] Specifically, after the transport vehicle transports the empty equipment to the target available parking space according to the first dispatch instruction, the transport vehicle sends an arrival signal to the server. After receiving the arrival signal from the transport vehicle, the server forwards the arrival signal to the forklift's on-board terminal. Then, the forklift driver can drive the forklift to the target available parking space according to the arrival signal to load the empty equipment unloaded to the target available parking space, and then transport the empty equipment to the corresponding empty equipment centralized storage area for transport vehicles to load and transport back to the corresponding supplier.

[0100] In this embodiment, by receiving the arrival signal sent by the transport vehicle and forwarding the arrival signal to the forklift's on-board terminal, the forklift proceeds to the target vacant parking space based on the arrival signal, loads the empty equipment unloaded at the target vacant parking space, and transports the empty equipment to the centralized storage area for loading and transport by the transport vehicle. This improves the efficiency of the forklift loading the empty equipment arriving at the target vacant parking space onto the transport vehicle, thereby improving the return empty efficiency.

[0101] In one embodiment, when the transport vehicle arrives at the target vacant parking space, an arrival signal sent by the transport vehicle is received, and the binding relationship between the pallet tag and the equipment tag is unbound according to the arrival signal, and the pallet tag is bound to the area tag of the area where the target vacant parking space is located.

[0102] It should be noted that the transport vehicle carries a pallet, and the pallet carries empty containers. The pallet label is linked to the container label of the empty container it carries. The pallet label is an RFID (Radio Frequency Identification) tag, containing basic pallet information such as the pallet number. The container label is also an RFID tag, containing basic container information such as the container code and supplier information. The area label is also an RFID tag, containing the location information of the area, and is generally affixed to the ground in the area it is located in.

[0103] Specifically, after the transport vehicle transports the empty equipment to the target vacant parking space according to the instructions of the first dispatch command, the transport vehicle will send an arrival signal to the server. After receiving the arrival signal sent by the transport vehicle, the server will unbind the binding relationship between the pallet tag and the equipment tag according to the arrival signal, and bind the pallet tag to the area tag of the area where the target vacant parking space is located.

[0104] In this embodiment, by receiving the arrival signal sent by the transport vehicle when it arrives at the target vacant parking space, and then unbinding the binding relationship between the pallet tag and the equipment tag according to the arrival signal, and binding the pallet tag with the area tag of the area where the target vacant parking space is located, the location of the pallet that has completed the transport task can be determined, making it convenient to use the pallet again.

[0105] In one embodiment, after the forklift loads the empty equipment unloaded to the target empty parking space, the method further includes: receiving a signal that the forklift has finished loading the empty equipment unloaded to the target empty parking space and generating a predetermined cooling signal, and suspending the reservation of the target empty parking space within a predetermined cooling time limit based on the predetermined cooling signal.

[0106] The pre-set cooling signal is a signal that suspends the reservation of a target vacant parking space within a preset time limit. The pre-set cooling time limit is a pre-set time limit for suspending the reservation of a target vacant parking space.

[0107] Specifically, after the forklift loads the empty equipment that was unloaded into the target vacant parking space, the forklift driver can send a signal to the server through the forklift's onboard terminal that the loading of the empty equipment into the target vacant parking space is complete. After receiving the signal that the forklift has finished loading the empty equipment into the target vacant parking space, the server generates a predetermined cooling signal to suspend the reservation of the target vacant parking space within a predetermined cooling time limit.

[0108] In this embodiment, by receiving a signal that the forklift has finished loading the empty equipment unloaded to the target empty parking space and generating a predetermined cooling signal, the reservation of the target empty parking space is suspended within a predetermined cooling time limit based on the predetermined cooling signal. In this way, the target empty parking space cannot be reserved within the predetermined cooling time limit, which can ensure that the forklift driver has enough time to occupy the parking space for unloading operations, thereby improving the return empty efficiency.

[0109] The following is for reference. Figure 3 The method for returning the device to empty will be described in detail below with a specific embodiment:

[0110] It should be noted that this embodiment uses AGV vehicles as transportation tools, and the server integrates MOM system, LES system and AGV system.

[0111] Specifically, the AGV (Automated Guided Vehicle) delivers the equipment loaded with materials to the production line. The production line consumes the materials loaded in the equipment. The server collects information on the assembly station's passing, leaving, and returning to the assembly line through the MOM (Multi-Manager) system, and deducts materials at the line-side workstations through the LES (Line-Side System). It instructs the AGV to organize and return to the assembly line and move to the material buffer area. It checks whether there are any materials that have left the assembly line in the AGV. If so, it instructs the AGV to move to the material buffer area. If there are no materials that have left the assembly line in the AGV, it confirms that the materials have been deducted and sends a return-empty instruction to the AGV system. The AGV system generates a corresponding scheduling instruction based on the return-empty instruction and sends the scheduling instruction to the AGV. The AGV then performs the empty equipment return operation according to the instructions of the scheduling instruction.

[0112] When the material loaded on the equipment is consumed and there is material in the material buffer, the LES system generates a second empty return instruction corresponding to the empty equipment, returning the empty equipment from the production line to the material buffer. This second empty return instruction is sent to the AGV system. The AGV system generates a third scheduling instruction based on the second empty return instruction and sends it to the AGV. The AGV transports the empty equipment from the production line to the material buffer according to the third scheduling instruction, loading material. After loading, the equipment continues production on the production line until the material loaded on the equipment is consumed and there is no material in the material buffer. Then, the LES system generates a first empty return instruction corresponding to the empty equipment, returning the empty equipment from the production line to the logistics gate position. This first empty return instruction is sent to the AGV system. The AGV system obtains the logistics gate position information corresponding to the empty equipment based on the first empty return instruction and determines the available gate position. It should be noted that the AGV carries a pallet, and the pallet carries an empty equipment. Large pallets correspond to large gate positions, small pallets correspond to small gate positions, and available gate positions are those without any pallets occupying them. When the AGV system determines that there are enough available parking spaces, it selects a target available parking space for reservation and marks the reserved parking space as reserved. Then, it generates a first dispatch instruction to direct the transport vehicle to the target available parking space and sends the first dispatch instruction to the AGV. The AGV goes to the target available parking space according to the first dispatch instruction and delivers the pallet and its empty equipment to the available parking space area. The information is simultaneously transmitted to the LES system. At this time, the AGV system controls the automatic unbinding of the pallet tag and the equipment tag of the empty equipment (the pallet tag is automatically bound to the area tag, which serves as a basis for subsequent receiving and binding verification of this parking space). When the AGV system determines that there are not enough empty storage slots and all the corresponding logistics gate slots are occupied by pallets, the AGV system generates a second scheduling instruction to instruct the transport vehicle to go to the empty equipment buffer area and sends the second scheduling instruction to the AGV. The AGV empties the equipment buffer area according to the second scheduling instruction, and at the same time feeds back the empty tasks to be returned to the forklift vehicle's onboard intelligent terminal in the form of a reservation queue. The forklift vehicle's onboard terminal interface displays and updates the empty / full occupancy information and reservation queue information for each logistics gate slot in real time (each slot is represented by three colors to indicate the occupancy status, reservation status, or empty status).

[0113] Once the AGV (Automated Guided Vehicle) transports empty equipment to the target available storage location, it sends an arrival signal to the AGV system. The AGV system then relays this signal to the forklift's onboard terminal. Based on the arrival signal, the forklift proceeds to the target available storage location and loads the empty equipment. The RFID scanning device on the forklift identifies the equipment tag on the empty equipment and retrieves the corresponding supplier information. The forklift then places the empty equipment in the corresponding supplier's centralized storage area. Logistics personnel then load the empty equipment into the supplier's transport vehicle and remove it. When the supplier needs to return empty equipment, the forklift retrieves the corresponding equipment for loading. Before loading, the transport vehicle's license plate information must be entered into the forklift's onboard terminal (in this case, the transport vehicle is a delivery vehicle). After delivery, the forklift terminal switches to the empty return interface to automatically import vehicle information, improving input efficiency. Before loading empty equipment, the RFID scanning device in the center of the forklift teeth reads the empty equipment information (equipment code, supplier information) on the equipment tag. Clicking the empty return button binds the equipment's empty return information. If the equipment belongs to the supplier corresponding to this vehicle, the binding is successful; if the equipment does not belong to this supplier, the binding fails, and the forklift terminal prompts the forklift driver to reconfirm and operate. Other empty equipment are processed in the same way. After the vehicle is loaded with empty equipment, clicking the empty return end button automatically uploads all bound information to the LES system, forming an electronic exit pass, and simultaneously transmits it to the ETCP system (Electronic Traffic Control Panel, Exit Management System). During the exit inspection, the gatekeeper can scan the vehicle information and automatically view the matching relationship between the loaded information and the actual items in the vehicle on a handheld terminal, forming a closed-loop management system.

[0114] When there are too many unloading tools and not enough empty pallets in the corresponding logistics gate slots, empty pallets are stacked and stored near all logistics gates to ensure receiving efficiency. At this time, the forklift driver can perform a slot reservation operation in the slot management interface of the forklift terminal and replenish empty pallets in the slots displayed in the forklift terminal. First, the forklift driver makes a slot reservation in the forklift terminal. After the empty pallet is placed, the pallet tag is bound to the area tag of the slot to facilitate subsequent normal receiving operations. At this time, the slot occupancy information is updated synchronously. Similarly, when there are too many line-side reservation tasks, the forklift driver can perform a slot clearance operation in the forklift terminal. The slot occupancy status in the forklift terminal is automatically updated to facilitate the AGV with reserved tasks to return empty tools to this slot. At the same time, the forklift removes the corresponding empty pallets for unified storage and management. Because the loading and unloading process is controlled by the forklift driver through the forklift's onboard terminal, to prevent situations where the forklift driver cannot secure a reserved parking space due to manual operation such as clearing parking spaces or replenishing empty pallets, a restriction logic is set in the forklift's onboard terminal system. Specifically, after the forklift driver operates on the onboard terminal, there is a certain delay in updating the parking space occupancy status. The forklift's onboard terminal feeds back the delay signal to the AGV system. Upon receiving the delay signal, the AGV system generates a pre-set cooling-off signal to suspend the reservation of available parking spaces within a pre-set cooling-off period. This ensures that the forklift driver has sufficient time for physical handling or other tasks, maintaining the order of the unloading operation. It should be noted that the pre-set cooling-off period in the AGV system corresponds to the delay period for updating the parking space occupancy status in the forklift's onboard terminal.

[0115] When a transport vehicle carrying empty return equipment is not fully loaded, it can call for empty equipment from the supplier through the forklift terminal. The forklift terminal will then send the call signal back to the AGV system. The AGV system will then automatically identify the supplier's equipment in the buffer area of ​​the workshop and prioritize sending it to the corresponding logistics gate position in the unloading area to improve the loading rate of empty return vehicles.

[0116] In this embodiment, a return-to-empty instruction is generated after the material loaded on the equipment is consumed. Based on the return-to-empty instruction, the corresponding logistics gate position information is obtained, and then an available position is determined. This allows for the reservation of target available positions. When there is a corresponding available position in the logistics gate's position area, the AGV is instructed to transport the empty equipment to that position. When there is no corresponding available position, the AGV is instructed to transport the empty equipment to the empty equipment buffer area. Then, a forklift removes the empty equipment from the corresponding logistics gate position and stores it in the corresponding centralized storage area for empty equipment according to the supplier. During loading, the vehicle's license plate information is bound to the equipment tag information of the empty equipment before loading, and the equipment is returned to the supplier, achieving a large-scale cycle. Furthermore, a predetermined cooling-off period is set after the AGV unloads to ensure that the forklift driver has sufficient time for physical handling or other operations, ensuring the order of the unloading operation. This effectively avoids mutual interference between AGV operations and manual operations, thereby improving return-to-empty efficiency.
