The unique identifier is uploaded to the ERP system for registration, and a one-to-one correspondence between the unique identifier and the transport carrier is established. Add notes to the task, including transit points and transit time.

[0008] Furthermore, the steps of extracting cargo flow tasks from the ERP system and parsing to obtain the origin, destination, and transport vehicle information include: Obtain the real-time location of the vehicle, build a real-time location viewing platform, and grant viewing permissions for the real-time location to registered users on the viewing platform. Based on the real-time location, the required time for the vehicle to reach the receiving location is calculated, and the order of the transfer facilities in the side chain is adjusted.

[0009] Furthermore, the steps of acquiring the transfer facilities in the receiving location, constructing a preset area, identifying transport vehicles entering the area, and determining the attribute information of the corresponding goods include: Locate the transfer facilities in the receiving area, which include at least loading and unloading robots and automated unloading trucks; Construct an electronic fence area centered on the receiving location; Detect transport vehicles entering the electronic fence area; Read the unique identifier corresponding to the transport vehicle; The cargo attributes are determined based on the unique identifier, and the attributes include cargo type, volume, and special requirements.

[0010] Furthermore, the step of constructing a data unit set and a resource scheduling structure corresponding to the circulation facilities based on the transport carrier and cargo attributes, and determining and ranking the availability of each circulation facility includes: Create a corresponding data unit for each transport vehicle and write the unique identifier into it; Integrate all data units to form a data unit set; Construct a resource scheduling structure and incorporate the transfer facilities into the resource scheduling structure; The circulation facilities are divided into idle facilities and busy facilities, and the load of idle facilities is determined; The availability of circulation facilities is calculated based on load and cargo attributes, and then sorted by availability.

[0011] Furthermore, the step of triggering an event response when the transport vehicle meets the preset triggering conditions, selecting the target data unit according to the correspondence, and linking the selection of the priority transfer facility includes: Establish a control link between data units and circulation facilities; Locate the delivery and signing point in the receiving area; Locate the target storage location through the ERP system; A circulation path is generated starting from the delivery point and ending at the target storage location; Control the flow facilities to perform cargo receiving and transfer operations.

[0028] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0029] Figure 1 This is a flowchart illustrating the overall process of an event-triggered linkage control method and system for cargo receiving facilities. In this embodiment of the invention, an event-triggered linkage control method for cargo receiving facilities includes: In Example 1, Figure 1 The implementation flow of the event-triggered linkage control method for cargo receiving facilities provided in this embodiment of the invention is illustrated below, and is described in detail below: S100: Extract the cargo flow tasks from the ERP system, wherein the tasks include the origin, destination and vehicle, determine the unique identifier of the cargo, and configure the correspondence between the unique identifier and the vehicle.

[0030] The tasks of cargo flow are extracted from the ERP system. These tasks mainly include: origin (transportation starting point), destination (transportation destination), and vehicle. The vehicle is the transport vehicle. The goods are numbered, a unique identifier is determined for each goods, and a correspondence between the unique identifier and the vehicle is established. In other words, by determining the vehicle, the goods being flowed can be quickly identified.

[0031] S200: Locate the transfer facilities in the receiving location, wherein the transfer facilities include at least: loading and unloading robots and automatic unloading vehicles; construct an electronic fence with the receiving location as the center and a preset distance as the radius; read the unique identifiers of all the vehicles within the electronic fence; determine the attributes of the goods, wherein the attributes include at least: goods type, volume and special requirements.

[0032] Locate the transfer facilities at the receiving location, including loading and unloading robots and conveyor belts; construct an electronic fence with the receiving location as the center, and monitor the vehicles entering the electronic fence; determine the unique identifier of all vehicles within the electronic fence, and trace back the attributes of the goods, including: the specific type of goods, the quantity or volume of goods, and the characteristic requirements of goods (such as storage temperature, transfer requirements), etc.

[0033] S300: Create a data block that corresponds one-to-one with the vehicle, synchronize the unique identifier to the corresponding data block through the correspondence, integrate all data blocks, generate a data stack, insert a side chain into the data stack, push the circulation facility into the side chain, dynamically determine the availability of each circulation facility, and sort the circulation facilities in descending order of availability, wherein the availability is used to characterize the ease or difficulty of the circulation facility in transferring goods.

[0034] The number of vehicles within the electronic fence is determined, and the same number of data blocks are created. The unique identifier corresponding to the goods within each vehicle is transferred to the corresponding data block. All data blocks are linked to generate a data stack. The data block is the basic unit for data storage, and the data stack is a collection of data blocks, primarily used for monitoring and arranging them. Sidechains are inserted into the data stack, and transfer facilities are transferred into the sidechains. Each sidechain is a collection of transfer facilities; each data block corresponds to at least one transfer facility. The availability of each transfer facility is determined, which is the ease with which the facility can transfer goods within its corresponding data block. If a transfer facility can easily transfer goods, its availability is high; if the transfer facility is busy, its availability is low. In the sidechains, transfer facilities are sorted in descending order of availability.

[0035] S400: Integrate a synchronous pop-up mechanism into the side chain. When the preset access control management system detects a vehicle, it backtracks the corresponding relationship and pops the blocks corresponding to the vehicle from the data stack. The synchronous pop-up mechanism is to synchronously pop the circulation facility that is ranked first in the side chain when several blocks are popped out of the data stack.

[0036] A synchronous pop-out mechanism is integrated into the sidechain. If the vehicle enters the receiving location, the access control system of the receiving location determines whether the vehicle has arrived. If it has arrived, the data blocks corresponding to the vehicle are popped from the data stack, and the synchronous pop-out mechanism is triggered to pop the top-ranked transfer facility from the sidechain. This transfer facility is then used to load, unload, and transfer the goods in the vehicle. The access control system is mainly used to verify the vehicle's license plate information and determine whether the correspondence mentioned in S100 is valid.

[0037] S500: Obtain control authority over the circulation facility, establish a control link between the blocks and the circulation facility, locate the signing point in the receiving location, integrate the signing point into the control link, use the ERP system to find the target storage location, and when the completion command sent by the vehicle is received, generate a circulation route with the signing point as the starting point and the target storage location as the ending point, integrate the circulation route into the control link, and start the circulation equipment.

[0038] Once the distribution facility is identified, control access to it is obtained, several control links are established with the facility, and a receipt point is determined at the receiving location. This receipt point is the area used for loading and unloading goods, and it is then sent to the vehicle. After sending, the ERP system is used to locate the target storage location, which is the intended storage location for the goods in the vehicle. A distribution route is generated with the receipt point as the starting point and the target storage location as the ending point. This route is then sent to the distribution equipment via the control links, and the equipment is activated to load, unload, and distribute the goods.

[0039] This demonstrates that by activating the pop-up transfer facility, goods in the vehicle can be loaded, unloaded, and transferred quickly without the need for multiple steps such as manual warehousing verification, determining the warehousing location, and unloading, thus greatly shortening the goods transfer process.

[0040] In this embodiment, after locating the video surveillance data, the segments containing the goods are extracted; within the segments, a reference object of a certain length is found, and the size of the reference object is compared with the size of the vehicle, and combined with the attributes, the size of the goods is determined. The availability of each target facility is adjusted, and the target facilities are adjusted synchronously to determine the adjustment result, wherein the adjustment result includes: reset, add, and remain unchanged. The following remains unchanged: loading, unloading and transferring of goods will be carried out solely using the target facility; Reset to: Push the current target facility back into the side chain, and re-determine the second-ranked transfer facility in the side chain as the target facility (this usually occurs when the actual size of the goods does not match the pre-determined goods attributes, and the transfer facility needs to be re-determined). Add as: If the cargo size is larger than the preset threshold, add the second-ranked transfer facility in the side chain to the target facility. At this time, the target facility contains two sets of transfer facilities. These two sets of transfer facilities are used to load, unload and transfer the vehicle together. Of course, "add", "reset" or "remain unchanged" can also be triggered by manual command.

[0041] In Example 2, Figure 2 The implementation flow of the event-triggered linkage control method for cargo receiving facilities provided in this embodiment of the invention is shown below. S100 is described in detail below: S101: Obtain the real-time location of the vehicle, build a real-time location viewing platform, and grant viewing permissions for the real-time location to registered users on the viewing platform.

[0042] Using GPS positioning technology, the real-time location of the vehicle is obtained and uploaded to the viewing platform. The registrants on the viewing platform are identified, and the registrants can be staff at the place of origin and destination, cargo users, etc. Viewing permissions are granted to the registrants.

[0043] S102: Based on the real-time location, calculate the time required for the vehicle to reach the receiving location, and adjust the order of the transfer facilities in the side chain.

[0044] Calculate the time required for the vehicle to reach the receiving location. The specific time required can be obtained from the map service provider, and the order of the transfer facilities can be adjusted.

[0045] For example, consider four transfer devices A, B, C, and D. A vehicle takes one hour to reach its destination. At the current moment, devices C and D are loading and unloading goods. If device A's loading and unloading capacity is more suitable for loading and unloading the vehicle, then the order of the transfer devices in the side chain is ABC / D. However, after one hour, transfer device C will complete its loading and unloading, and C is more suitable for loading and unloading the vehicle than A. Therefore, the order in the side chain needs to be adjusted to CABD.

[0046] In Example 3, Figure 2 The implementation flow of the event-triggered linkage control method for cargo receiving facilities provided in this embodiment of the invention is shown below. S100 is further described in detail below: S103: Edit the coding rules for goods, generate a unique identifier, and upload the unique identifier to the ERP system.

[0047] Determine the coding rules for the goods and assign a unique identifier to each batch of goods, then upload this unique identifier to the ERP system.

[0048] S104: Add a note to the task, wherein the note includes at least: transfer point and transfer time.

[0049] Add notes to the task, including the required transport temperature for the goods and the maximum transit time.

[0050] In Example 4, Figure 3 The implementation flow of the event-triggered linkage control method for cargo receiving facilities provided in this embodiment of the invention is shown below. S200 is described in detail below: S201: Locate all vehicles within the electronic fence, configure the priority of each vehicle according to the correspondence and attributes, and sort the blocks in the data stack in descending order of priority.

[0051] Find all vehicles within the electronic fence. If there are multiple vehicles, determine the priority of each vehicle based on the attributes of the goods. The higher the priority, the faster the goods will be loaded and unloaded. In other words, sort the data blocks in the data stack according to the order of priority from high to low.

[0052] For example, if there are three vehicles, A, B, and C, in an electronic fence, and all three vehicles have the same priority, then the data stack corresponding to each vehicle is sorted according to its distance from the receiving location. The closer the distance, the higher the corresponding data stack is in the order. If A is closest to the receiving location, followed by B, then the data stack will be sorted as A, B, and C. That is, A will be loaded and unloaded first, then B, and finally C. However, there is another situation where A has a higher priority than B and C. If all three vehicles have arrived within the electronic fence, then A should be loaded and unloaded first, and the order of vehicles based on distance is no longer followed. In other words, as long as there is a higher priority vehicle within the electronic fence, it will be loaded and unloaded first.

[0053] S202: Determine the waiting time for each of the vehicles, generate feedback information, and push the feedback information to the vehicles.

[0054] When a vehicle arrives at the receiving location, if other vehicles are being loaded or unloaded, the arriving vehicle needs to wait. The specific waiting time needs to be determined, and the waiting time can be entered by the staff. The waiting time is used to generate feedback information, which is then sent to the vehicle.

[0055] In Example 5, Figure 4 The implementation flow of the event-triggered linkage control method for cargo receiving facilities provided in this embodiment of the invention is shown below. S300 is described in detail below: S301: Divide the circulation facility into busy facilities and idle facilities, and determine the load of each idle facility.

[0056] The flow facilities in the side chain are divided into busy facilities and idle facilities. Busy facilities are those that are currently loading and unloading goods. The load of each idle facility is determined, which is the amount of goods that the flow facility can load and unload.

[0057] S302: Compare the load and attributes, define the circulation facility with the highest availability as the target facility, and establish a mapping between the target facility and the blocks.

[0058] By comparing the attributes and load of the cargo in the vehicle, the target facility is identified. The target facility is the most suitable transfer equipment for loading and unloading the vehicle. The target facility for each vehicle is determined and a mapping is established.

[0059] In Example 6, Figure 5 The implementation flow of the event-triggered linkage control method for cargo receiving facilities provided in this embodiment of the invention is shown below. S400 is described in detail below: S401: When the access control management system detects a vehicle, it verifies the vehicle and the unique identifier, and after successful verification, it generates a trigger signal and migrates the trigger signal to a block.

[0060] When the access control system detects a vehicle, it verifies the vehicle and its unique identifier to determine whether the vehicle corresponds to the task. If the verification is successful, a trigger signal is generated. The trigger signal is mainly used to pop the data block corresponding to the vehicle from the data stack.

[0061] S402: When the data block receives the trigger signal, the data block is popped from the data stack, the synchronous pop mechanism is activated, and the target facility is popped from the sidechain across the mapping.

[0062] When the data block receives the trigger signal, it will be popped from the data stack. According to the synchronous pop-out mechanism, the target facility corresponding to the data block and the vehicle will be popped from the side chain. The target facility will then be used to load and unload the cargo in the vehicle corresponding to the data block.

[0063] In Example 7, Figure 6 The implementation flow of the event-triggered linkage control method for cargo receiving facilities provided in this embodiment of the invention is shown below. S500 is described in detail below: S501: After the vehicle and unique identifier are verified, obtain the video surveillance data at the signing point, extract the signing segment, and mark the unique identifier into the signing segment.

[0064] Once the vehicle arrives at the receiving location, the entire loading and unloading process of the goods is recorded using a video surveillance system. The corresponding video surveillance data is then identified, and the signature segment from the video surveillance data is extracted and marked with a unique identifier.

[0065] S502: Store the signed-in fragment and generate a circulation catalog.

[0066] The signed-out segments are stored to obtain a collection of signed-out segments, and a directory is created for the collection, which is also the circulation directory.

The event-triggered linkage control method for cargo receiving facilities according to claim 1, characterized in that, The steps of establishing the control association between the data unit and the circulation facility, determining the cargo receiving point and target storage location, generating the circulation path, and controlling the circulation facility to perform cargo receiving and transfer operations include: Establish a control link between data units and circulation facilities; Locate the delivery and signing point in the receiving area; Locate the target storage location through the ERP system; A circulation path is generated starting from the delivery point and ending at the target storage location; Control the flow facilities to perform cargo receiving and transfer operations.

8. A linkage control system for a cargo receiving facility based on event triggering, characterized in that, The system is used to implement the event-triggered cargo receiving facility linkage control method as described in any one of claims 1 to 7, and the system's operation includes: Obtain task information on cargo flow; the task information includes at least the place of origin, the place of receipt, and the information of the transport vehicle; generate a unique identifier for the cargo; and establish a correspondence between the unique identifier for the cargo and the transport vehicle. The system acquires the transfer facilities in the receiving location and constructs a preset area range. It then identifies the transport vehicles entering the area range and determines the attribute information of the corresponding goods. Based on the transport carrier and cargo attributes, a set of data units and a resource scheduling structure corresponding to the circulation facilities are constructed to determine the availability of each circulation facility and sort them. When the transport vehicle is detected to meet the preset triggering conditions, an event response is triggered, the target data unit is selected according to the correspondence, and the circulation facility with priority in sorting is selected in conjunction with the response. Establish a control association between the data unit and the circulation facility, determine the cargo receiving point and target storage location, generate the circulation path, and control the circulation facility to perform cargo receiving and transfer operations.
