Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0037] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0038] After analyzing and studying the existing technologies, it is found that every time a deployment project is implemented, a large number of routes need to be designed and planned, and they need to be configured in the WCS warehouse sorting control system. The more starting positions and turning points there are, the more data needs to be configured, and sometimes it is a huge amount of data. At the same time, when the WCS warehouse sorting control system receives a PLC action request, due to the huge amount of data, it takes a long time to retrieve and calculate in the database, resulting in negative situations such as weekly packaging movement jams, slow operation speed, and reduced efficiency.

[0039] Therefore, this solution aims to provide a logistics sorting scheduling method based on Map cross table. This method uses a Map cross table stored in the WCS warehouse sorting control system to realize the instruction storage of each interactive request point of the entire logistics sorting and conveying system. The configuration method of the Map cross table is simple and clear, and there is no need to configure any path information of the starting position and intermediate nodes. When the system starts, the Map cross table will be loaded into the memory first. When an action request occurs, the WCS warehouse sorting control system does not need to do any calculations. It can directly obtain the instruction information from the memory through the Linq query statement based on the current position and destination and send it to the PLC.

[0040] This solution involves a warehouse sorting control system (WCS), which can also be called an equipment dispatching system. This system is a management control system between the WMS system and the PLC system. It can coordinate the operation of various logistics equipment, such as conveyors, palletizers, shuttles, robots, guide vehicles and other logistics equipment. It mainly realizes the integration, unified dispatching and monitoring of various equipment system interfaces.

[0041] Generally, the automatic warehousing system can be roughly divided into three levels. The top level is the WMS warehouse management system, which is responsible for processing the warehousing business logic; the bottom level is the specific logistics equipment, such as stackers, robots, AGV systems, etc.; WCS is located in the middle layer between WMS and logistics equipment, responsible for coordinating and scheduling various logistics equipment at the bottom level, so that the bottom-level logistics equipment can execute the business processes of the warehousing system, and the process is executed completely in accordance with the pre-set process of the program.

[0042] In the following, a method for logistics sorting and scheduling based on a Map cross table proposed in this solution will be described in detail in conjunction with the accompanying drawings. Specifically, the method includes:

[0043] Step S1, obtaining a cargo sorting action request;

[0044] Step S2, according to the cargo ID information contained in the sorting action request, retrieving the destination location corresponding to the cargo;

[0045] Step S3: Based on the positional relationship between the current position of the goods and the destination position, determine the sorting execution instruction message of the goods from the pre-set Map cross table and send it to the requesting party.

[0046] In step S1 of this solution, sorting action requests corresponding to different goods can be received, and attribute information, status information, etc. of the goods can be parsed from the sorting action requests. Specifically, the ID information, current location information, and destination information of the goods can be added to the sorting action request; and abnormal status information such as slippage, jamming, signal loss, and overrunning of the cargo box / VGA trolley currently transporting the goods can also be added. The parsed attribute information and / or status information of the goods is used as the data basis for subsequent search for corresponding sorting execution instruction information.

[0047] In one embodiment, if Figure 2 As shown, a request list can be configured in the warehouse sorting control system. After receiving a sorting action request, the ID information, current location information, destination information, etc. of the goods are listed in the list.

[0048] In this solution, the sorting action request can be issued by an external device, which collects the attribute information of the goods such as ID information, or the goods status information such as current location information, destination information, abnormal status, etc. in real time; according to the attribute information and / or status information of the goods, a corresponding sorting action request is generated. In one embodiment, a PLC can be used as an execution controller to monitor the transportation status of the goods in real time and collect the attribute information and / or status information of the goods. The attribute information and / or status information of the goods is added to the request, and a sorting action request is generated and sent to the warehouse sorting control system.

[0049] In step S2, the solution uses the ID information and destination information of the goods to retrieve the final destination of the goods to ensure the accuracy of the goods delivery. Specifically, the real destination of the goods can be traversed from the database or data list according to the goods ID information in the sorting action request to prevent the problem of wrong delivery of goods due to abnormal conditions during the goods delivery process.

[0050] In one embodiment, if Figure 2 As shown, the task data list can be configured in the warehouse sorting control system, and the goods can be bound to the destination location and stored in the list. According to the ID information of the goods, the destination location of the goods can be locked from the task data list.

[0051] In step S3 of this solution, the positional relationship between the current position of the goods and the destination position is first determined. Specifically, the specific position of the current goods in the sorting path is determined through the pre-built binding relationship between the goods and the destination position, and the sorting path for the goods to reach the destination position; then, the positional relationship between the current position of the goods and the destination position is determined.

[0052] After determining the positional relationship between the current location of the goods and the destination location, the preset Map cross table is traversed to determine the sorting execution instruction message of the corresponding goods, and then fed back to the requesting party. Figure 2 As shown, the overall sorting actions corresponding to all goods and each interaction point (for example, Figure 2 The Map cross table of sorting actions (the code reading point in the warehouse) is pre-stored in the warehouse sorting control system. When in use, the current interaction point position of the goods is determined according to the positional relationship between the current position of the goods and the destination position, and then the corresponding sorting execution instruction message is searched from the Map cross table stored in the memory through the Linq query statement. Then, the warehouse sorting control system feeds back the sorting execution instruction message to the PLC.

[0053] In this solution, the PLC sends a sorting instruction based on the received sorting execution instruction message to complete the execution operation of cargo transportation and sorting.

[0054] The above-mentioned logistics sorting and scheduling method based on the Map cross table can effectively improve the sorting control speed of the WCS system. This method does not need to configure a large amount of path information from the starting point to the destination and various possible path nodes. The WCS system can directly obtain the instruction information that should be executed without complex calculations and retrieval. By embedding the Map cross table in the memory of the WCS system, the process of retrieving from the database is avoided, and the instruction data can be obtained by directly operating the memory, thereby improving the interaction speed between the WCS system and the PLC, and speeding up the overall execution speed of the system. Ultimately, it can be achieved that no matter where the logistics box is imported in the system, it can be moved at will, moved away from the original position, or the import point is not the starting position in the data. As long as any interaction point is passed, the WCS system can guide the logistics box back to the right path and finally delivered to the correct location.

[0055] The above-mentioned logistics sorting and scheduling method based on Map cross table can form a good integration with the logistics sorting and scheduling device, which is conducive to the promotion and implementation of the system. Specifically, the logistics sorting and scheduling device includes: a receiving module, a retrieval module and a matching module. The receiving module obtains the sorting action request of the goods; then, the retrieval module retrieves the destination location corresponding to the goods according to the goods ID information contained in the sorting action request; finally, the matching module determines the sorting execution instruction message of the goods from the pre-set Map cross table based on the position relationship between the current position and the destination location of the goods, and sends it to the requesting party. Among them, the relationship between the goods and the destination location can be stored in the task data list, so that the query module can find the corresponding destination location according to the goods ID information in the sorting action request.

[0056] In one embodiment, if Figure 2 As shown, after receiving the sorting action request of the goods, the receiving module can parse the request and present the parsed information in the sorting action request in the request list. The search module uses the ID information of the goods and determines the real destination location of the goods according to the binding relationship between the goods and the destination location recorded in the task data list. Then, through the matching module, based on the pre-established binding relationship with the destination location and the sorting path for the goods to reach the destination location, the positional relationship between the current location of the goods and the destination location is determined according to the current location of the goods on the sorting path; then, the Linq query statement is used to find the corresponding sorting execution instruction message from the Map cross table stored in the memory and feed it back to the PLC controller.

[0057] In this solution, the control module is a device for real-time collection of cargo information and execution of instructions, and can adopt control devices such as PLC controller and host computer.

[0058] In this solution, a configuration module can also be added to configure the Map cross table and / or the binding relationship between goods and destinations and the sorting path in the WCS system, thereby improving the flexible configuration capability of the system.

[0059] In addition, in this solution, the PLC controller and the WCS system can achieve stable real-time communication between the two through the communication protocol module.

[0060] The following uses hospital material distribution as an example to further illustrate this plan.

[0061] like Figure 2 As shown, each logistics turnover box carrying goods has a uniquely identified paper barcode or a uniquely identified RFID chip box code. The box will contain materials and consumables to be sent to the destination. When sending, the box code will be bound to the destination location and stored in the task data table of the WCS system. Through the question-and-answer interaction between the WCS system and the PLC controller, the real destination location of the goods is locked through the task data table, and the Map cross-command table is used to determine the instruction information for guiding the transportation of the logistics turnover box, which is sent to the PLC controller through the WCS system, so that the logistics turnover box is transported to the final destination through the PLC controller. In this example, the Map cross-table can be loaded into the memory before the WCS system is run. The box code and destination location of the sending department are bound and established in the task data table of the WCS system to form a data relationship between the box code and the destination location.

[0062] When the logistics box is imported from the originating department logistics system, it will go through the redirection request interaction point (e.g. Figure 2 When the PLC reaches the code reading point in the cargo box, the PLC collects the box code and position of the requested point, and requests the WCS system to execute the action instruction through the communication interaction module with the WCS system; after the WCS system receives the request instruction from the PLC controller, it retrieves the destination position of the requested box number, combines the destination position with the current position of the cargo box, and uses the Linq query statement to cross-locate the instruction information to be executed from the Map cross table in the memory horizontally and vertically; then, the WCS system sends the instruction information to the PLC controller through the communication interaction module with the PLC controller, and the PLC controller executes the action instruction to realize the steering distribution of the logistics box.

[0063] Through the above method, there is no need to configure a large amount of path information. The turning instruction information can be recorded and obtained through a simple and intuitive Map cross table. This table includes all the possibilities of the path, which is flexible, fast, clear and simple, and the requested instruction information can be obtained without calculation.

[0064] The solution described in the present application utilizes a Map cross table stored in memory instead of a complex path algorithm to achieve a fast, computation-free way of acquiring sorting scheduling instructions, thereby realizing flexible scheduling and a loosely coupled mechanism. In the event of abnormal situations such as slipping, box jamming, signal loss, and overrunning of the logistics box, the box can be automatically put on track based on the next interaction point information contained in the sorting execution instruction message obtained from the Map cross table.
