[0032] See also Figure 1 , Figure 1 It is a structural diagram of a data processing system based on a warehouse control system provided in an embodiment of the present application. The data processing system includes a hardware device 11, a data acquisition gateway 12 and a warehouse control system 13, wherein the data acquisition gateway 12 includes a server 121 and an information model 122 based on the process control object linking and embedding unified architecture OPC UA, and the warehouse control system includes a client based on OPC UA.

[0033] according to Figure 1 As shown, the hardware device 11 is used to provide description information of the hardware device 11, the data acquisition gateway 12 includes an OPC UA-based server 121 and an information model 122, the server 121 is used to map the nodes in the information model 122 and the measuring points in the server 121, so that the information model 122 is associated with the description information of the hardware device 11, and the warehouse control system WSC13 includes an OPC UA-based client 131, which is used to communicate with the server 121 through the client 131. Optionally, the data acquisition gateway is established based on OPC UA.

[0034] Optional, such as Figure 2As shown, the data processing system includes not only hardware equipment 11, data acquisition gateway 12 and warehouse control system 13, but also a warehouse management system (WMS). The warehouse management system WMS is used to send warehouse management tasks to the warehouse control system WSC.

[0035] In the embodiment of the present application, Figure 3 1 is a structural diagram of a data processing system based on a warehouse control system provided in an embodiment of the present application. The data acquisition gateway 12 also includes a hardware device driver adaptation module 123 and a hardware device driver setting module 124. The hardware device driver adaptation module 123 includes a driver for driving the hardware device 11, and the hardware device driver setting module 124 is used to set a driver not included in the hardware device driver adaptation module 123.

[0036] In the embodiment of the present application, the hardware device is not limited to including a wireless radio frequency identification device RFID, a sensor, a stacker, a roller line, a scanner, an automatic guided transport vehicle and a motor, and may also include other suitable hardware devices. Since the information model is associated with the description information of the hardware device, the information model is not limited to including the wireless radio frequency identification RFID information model, the sensor information model, the stacker information model, the roller line information model, the scanner information model, the automatic guided transport vehicle information model and the motor information model.

[0037] This application will specifically introduce the data processing system based on the above text. The warehouse control system WCS is connected to the data acquisition gateway based on OPC UA. The warehouse control system WCS integrates an OPC UA-based client, and the data acquisition gateway contains an OPC UA-based server. The communication between the warehouse control system WCS and the data acquisition gateway is achieved through the connection between the client and the server. The warehouse control system WCS establishes a connection with the data acquisition gateway through the information model, so that the client can read and modify the descriptive information in the information model, for example, obtain the identification of the hardware device in the information model and call the control mode in the information model to complete data collection and control operations on the hardware equipment.

[0038] The warehouse control system connects to the warehouse management system, exchanges information through a WEB server or an intermediate data table, and receives warehouse management tasks from the warehouse management system, such as warehousing, outbound, inventory, replenishment, etc. After the warehouse control system completes the warehouse management task, it can feedback the task execution status to the warehouse management system, such as outbound completion, inbound completion, warehousing to a certain location, etc. Correspondingly, the warehouse control system WCS can optimize the task sequence based on the principle of maximizing efficiency based on the received inbound and outbound tasks using ant colony algorithms, annealing algorithms, and genetic algorithms. Based on the optimized task sequence, the WCS system centrally controls the hardware equipment through the WCS system information model.

[0039] The data acquisition gateway is connected to all hardware devices, such as Siemens PLC, Mitsubishi PLC, Omron PLC, Hikvision AGV, KUAK robot and ABB robot. The hardware device driver adaptation module stores the driver programs of the above hardware devices, but the pre-built-in driver information is not limited to the above hardware devices.

[0040] However, the data acquisition gateway cannot contain drivers for all hardware devices on the market. To solve the problem of adding new devices, the present invention supports the function of importing new hardware device drivers in the form of plug-ins to facilitate the rapid access of new hardware devices. That is, when the underlying hardware device type changes, it is only necessary to develop a new device driver separately in the hardware device driver setting module, and then import the driver of the new hardware into the data acquisition gateway in the form of a plug-in, so as to realize the communication and interaction between the warehouse control system WCS and the new hardware devices, without the need to re-modify the program code of the warehouse control system WCS.

[0041] After the data acquisition gateway is connected to the hardware device, the OPC UA measurement point information is associated with the description information of the hardware device in the data acquisition gateway, so that the description information of the hardware device is collected into the data acquisition gateway. At this time, the description information is only the single point information of the hardware device, and does not provide the device semantics for the warehouse control system WCS operation.

[0042] This application supports the information modeling function of the warehouse control system WCS, imports the established information model of the hardware equipment into the data acquisition gateway, configures the mapping between the information model and the OPC UA measurement point in the service, and finally realizes the association between the information model of the warehouse control system WCS and the description information of the hardware equipment, so that the hardware equipment has semantics.

[0043] Optionally, there are two parts in the OPC UA architecture: method signature and method implementation. When the warehouse control system WCS calls a method, it calls the signature of the method, and the specific method execution is in the function engine of the OPC UA data acquisition gateway.

[0044] In the embodiment of the present application, the embodiment of the present application also provides a flow chart of a data processing method based on a warehouse control system WCS, the method is applied to a data processing system, the data processing system includes a warehouse control system WSC, a data acquisition gateway and hardware equipment, the data acquisition gateway includes a server and an information model based on OPC UA, and the warehouse control system WSC includes a client based on OPC UA; Figure 4 As shown, the method includes:

In an embodiment of the present application, the description information corresponding to different hardware devices is inconsistent, that is, the description information of the hardware device is different due to the different types of hardware devices. The description information of the hardware device is not limited to the above.

[0050] like Figure 5 The stacker information model and example shown in the figure are single-track single-car models. The stacker information model contains 9 variables and 3 methods. The warehouse control system WCS can view the status of a certain numbered stacker, its current location, and horizontal and vertical power information based on the semantics of the model, and can call the methods provided by the model to start, stop, and move to control the action of the stacker.
