[0036] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0037] like Figure 1 As shown, an embodiment of the present invention provides a hardware device control method, comprising:

[0038] Step 11, receiving a database control instruction sent by the warehouse management system, wherein the database control instruction includes an identifier of the target data;

[0039] Here, the database control instruction is an SQL command, for example, the database control instruction may be SELECTDBO.XGate_SendRdpData(@Gzid), wherein @Gzid is the identifier of the target data. The identifier of the target data is stored in the database by the warehouse management system before step 11.

[0040] Step 12, initiating a communication request to the server program according to the identifier of the target data in the database control instruction through the pre-stored common language runtime CLR assembly;

[0041] Here, the CLR (Common Language Runtime) assembly is pre-written by the developer and injected into the database engine. The CLR (Common Language Runtime) assembly is used to control the servo program. When the database engine receives the database control instruction sent by the warehouse management system, the database engine first parses the control instruction to obtain the identifier of the target data; then calls the CLR assembly to construct a data format suitable for HTTP or RPC protocol transmission according to the identifier of the target data. The converted command is communicated with the servo program through HTTP or RPC protocol.

[0042] Step 13, receiving a response from the servo program;

[0043] Here, the server receives the command sent by the database engine and parses the command to obtain the identifier @Gzid of the target data.

[0044] Step 14, acquiring target data from a database according to the identifier of the target data in the response of the servo program; the target data includes routing information and service information of the current communication;

[0045] Here, the target data is found in the database according to the identifier of the target data, the target data is stored in the temporary parameter table of the database, and the target data is stored in the database before the warehouse management system sends the database control instruction to the database. The servo program can find the corresponding temporary parameter table in the database according to the identifier of the target data, thereby obtaining the target data therefrom.

[0046] Step 15: Send instructions to the controller of the target hardware device through the servo program according to the business information of the target data, and control the target electronic device through the controller.

[0047] Here, after the servo program obtains the target data, it sends a control instruction to the controller, and the controller controls the target electronic device according to the received control instruction.

[0048] In this embodiment, the hardware device control system corresponding to the above hardware device control method is as follows: Figure 2 As shown, it includes a WMS (warehouse management system) system, a database, a servo program, a controller and hardware devices, and the hardware devices can be electronic tags, AGVs, stackers, gratings, etc. Through the hardware device control method of the present invention, all these hardware devices can be controlled. The electronic tags are installed on the warehouse shelves, and the installation method is as follows Figure 3 As shown, preferably, one electronic tag corresponds to one stored item.

[0049] In an optional embodiment of the present invention, the target data is pre-stored in a temporary parameter table of a database before the warehouse management system sends the database control instruction; the business information of the target data includes an identifier of the target data.

[0050] In this embodiment, taking the warehouse management system needing to send SQL instructions to the database to light up the electronic tag as an example, before the database receives the database control instruction sent by the warehouse management system in step 11, that is, before the warehouse management system sends the database control instruction to the database, the warehouse management system will connect to the database to store the information to be sent (including the identification of the target data) in the parameter temporary table in the database. The parameter temporary table mainly stores three types of information, including routing information, business information, display content information and display mode. The routing information includes: sending service end and receiving service end; the business information includes: gateway serial number, bus serial number, device serial number, operation type, message id (that is, the identification of the target data); the display content information is the content displayed on the electronic tag screen after the electronic tag is lit, including product name, product description, packaging unit, display direction, storage location, quantity, etc. When the electronic tag is to be lit, the WMS system needs to store the display content information in the database; when the electronic tag is to be turned off, the WMS system only stores the routing information and business information in the parameter temporary table, and no longer needs to store the display content information. The display mode includes light source color and background color. The temporary parameter table is shown in Table 1 below:

[0051] Table 1, temporary table of parameters

[0052]

[0053]

[0054] The WMS system randomly generates the identifier of the target data and stores the identifier of the target data together with the data to be stored in the temporary parameter table of the database. The identifier of the target data is used to identify the target data during the communication process between the servo program and the database.

[0055] In an optional embodiment of the present invention, step 14 may include:

[0056] Step 141, according to the identifier of the target data, obtaining a temporary parameter table corresponding to the identifier of the target data in a database;

[0057] Step 142, obtaining the target data in the temporary parameter table; the temporary parameter table stores the target data in the form of message unique value, parameter name and parameter value.

[0058] In this embodiment, after receiving the request, the servo program searches the database for the corresponding temporary parameter table according to the identifier Gzid of the target data in the command, and obtains the target data from the temporary parameter table.

[0059] In an optional embodiment of the present invention, step 15 may include:

[0060] Step 151, determining a target hardware device in at least one hardware device according to the parameter values ​​of the gateway number, bus number and device number in the service information; and,

[0061] Step 152, determining the instruction to be executed on the target hardware device according to the parameter value of the operation type in the service information;

[0062] Step 153: Send instructions to the controller of the target hardware device through the servo program.

[0063] In this embodiment, the servo program queries the gateway number, bus number and device number in the temporary parameter table to determine the target hardware device to be controlled. According to the parameter value of the operation type, the instruction to be executed on the target hardware device is determined. Taking the electronic tag as an example, when the parameter value of the operation type is Cmd_Display, it means lighting up the electronic tag; when the parameter value of the operation type is Cmd_Clear, it means turning off the light. After the servo program obtains the target hardware device to be controlled and the instruction to be executed on the target hardware device by querying the temporary parameter table, the servo program sends instructions to the controller to control the hardware device.

[0064] In an optional embodiment of the present invention, step 152 may include:

[0065] Step 1521: Determine whether to execute a light-on tag instruction or a light-off tag instruction on the target hardware device according to the parameter value of the operation type in the business information.

[0066] In this embodiment, an electronic tag is taken as an example, and the electronic tag is controlled to light up or go out by the controller. Of course, it is understandable that when the target hardware device is other, the operation type will correspond to other instructions.

[0067] In an optional embodiment of the present invention, when a light label instruction is to be executed on the target hardware device, the target data also includes display content information, and the servo program sends a light label instruction to the controller of the target hardware device according to the business information and displays the display content information on the target hardware device.

[0068] In the above embodiment of the present invention, in order to realize the interaction between the servo program and the target hardware device, the .NET dynamic library (Ptl.Device.dll) and Java package (ptl.device.jar) of the underlying communication that directly interacts with the device provided by the manufacturer of the target hardware device are required. The servo program calls the device control method through the communication library to handle the device callback event or error.

[0069] The communication library uses the XGate class as the main entry point to manage all devices directly or indirectly connected to it. The servo program uses the methods provided by the communication library in the following steps:

[0070] 1. Initialize the controller X-Gate;

[0071] 2. Add the target hardware device to different buses of the controller X-Gate;

[0072] 3. Start the communication of the controller working bus;

[0073] 4. Subscribe to the interaction events or failures between the communication bus and the device;

[0074] 5. Light up or turn off the electronic tag node device to implement the business logic of the on-site solution;

[0075] 6. Handle the callback events of the equipment and implement the business logic of the on-site solution.

[0076] The specific process of the above hardware device control method is described below with a specific embodiment:

[0077] Example 1: Light up the electronic tag

[0078] First, WMS will connect to the database to store the information to be sent into the parameter temporary table (HzTemp), and execute the assembly definition SQL command: SELECT DBO.XGate_SendRdpData(@Gzid);

[0079] Then the database sends a request to the servo program through the RPC protocol. After receiving the request, the servo program queries the corresponding parameter name and content value in the database through the unique ID (Gzid) in the command. According to the values ​​of the gateway, bus, and device serial number in the parameters, the specific device is found, and the corresponding interface provided by the device manufacturer is called to send the message to the controller. Finally, the message reaches the electronic tag, which is successfully lit and displays the display content in the parameter.

[0080] In an optional embodiment of the present invention, the hardware device control method further includes:

[0081] When the target hardware device receives the input instruction and calls back the servo program according to the input instruction, it receives the data storage instruction sent by the servo program and calls the specified storage process to store the data into the target table of the database.

[0082] In this embodiment, the servo program can also receive callbacks from the controller and store data in the database. When the staff operates the + and - buttons of the electronic tag to modify the value of the displayed content quantity, and then presses the OK button of the electronic tag, the device communication library will call back the servo program through the communication thread. After receiving the message, the servo program writes the information to the database WMS_DZBQ_RETURN_T table and calls the specified stored procedure WMS_DZBQ_return. WMS can customize the message processing logic in this stored procedure.

[0083] The following is a specific example of the specific application process of the above embodiment in the scenario of delivery and picking:

[0084] Example 2: Picking and dispatching

[0085] WMS receives the order to be shipped, calculates the location of the items to be picked, and occupies the inventory. The employee operates WMS to select the picking order and issue the picking instruction, and then begins the interaction with the electronic tag. The specific process is as follows:

[0086] 1.WMS connects to the database to organize the parameter information required for lighting (gateway serial number, bus serial number, device serial number, operation type, message ID, product name, product description, packaging unit, display direction, storage location, quantity, light source color, background color), and stores the information to be sent in the parameter temporary table (HzTemp) to generate a unique ID (gzid) for this communication;

[0087] 2. Execute the assembly definition SQL command: SELECT DBO.XGate_SendRdpData(@Gzid) to initiate communication with the servo program;

[0088] 3. After receiving the request, the server program queries the database for the corresponding parameter name and content value through the unique ID (Gzid) in the command;

[0089] 4. The servo program finds the specific device based on the values ​​of the gateway, bus, and device serial number in the parameters, and finally displays the parameters on the electronic label through the communication library device control method provided by the device manufacturer;

[0090] 5. Finally, the electronic tag lights up and displays the content, and the channel indicator light tower corresponding to the electronic tag also lights up;

[0091] 6. The employee walks to the corresponding lit electronic tag, picks the corresponding goods according to the displayed content, and presses the OK button of the electronic tag after processing is completed. The device communication library will call back the servo program through the communication thread;

[0092] 7. After receiving the message, the server program writes the information to the WMS_DZBQ_RETURN_T table in the database and calls the specified stored procedure WMS_DZBQ_return. In this stored procedure, WMS marks the order as having been picked based on the unique ID of the communication and enters the subsequent outbound review step.

[0093] The code for lighting up the electronic tag in the above embodiment of the present invention is as follows:

[0094]

[0095]

[0096] The code in the process of extinguishing the electronic tag in the above embodiment of the present invention is as follows:

[0097]

[0098]

[0099] The above method of the present invention separates the control logic of the hardware from the control technology, and provides a set of fast hardware equipment control methods, so that users can independently and flexibly control the modern facilities in their own warehouses, giving users room to play freely, reducing the difficulty of learning and training for user operation and maintenance personnel, and reducing the labor costs of enterprises. The control logic of the electronic tags is initiated by the database engine in the form of SQL commands. Users do not need to learn more programming knowledge, but only need to understand simple SQL syntax, which greatly reduces the control difficulty of electronic tags. The control logic of the hardware is edited by the user independently and is no longer restricted by software developers. In addition, the hardware equipment control is flexible. In different business scenarios, different business needs can be met by hardware without the need for re-development.
