Description

Technical Field

[0001] The present application relates to the field of warehouse management, and in particular to a warehouse cargo door management system and a processing method thereof. Background Art

[0002] Material management is widely used in the production of various enterprises. Efficient management of various materials (or goods) stored in warehouses is a very important production link. However, many existing warehouse cargo doors still rely on manual operation and management, which requires high labor costs and cannot achieve real-time monitoring and control. Specifically, there are:

[0003] (1) Traditional manual operation and management methods are often inefficient and cannot meet the needs of large-scale warehouses. Manual operation may take a long time, thus affecting the efficiency of goods entering and exiting and the productivity of the warehouse. In addition, manual operation is also prone to traffic congestion and accumulation, further reducing the operational efficiency of the warehouse;

[0004] (2) Existing warehouse cargo door management often lacks real-time monitoring and tracking functions. It is difficult for warehouse managers to accurately understand the status and working conditions of the cargo doors. Once a failure or abnormality occurs, it takes a long time for the manager to discover and take appropriate measures. This will cause delays and losses, affecting the overall operational efficiency of the warehouse. Existing warehouse cargo door management often cannot effectively record and analyze the opening and closing time of the cargo doors, as well as the number and time of goods entering and leaving. This makes it difficult for warehouse managers to accurately evaluate the efficiency and benefits of warehouse operations.

[0005] In order to overcome the above problems, manufacturing companies have generally established corresponding management systems to uniformly manage warehouse materials. However, existing material management systems and their management methods usually focus on recording the storage status of materials in online systems, but often ignore the management of warehouse cargo doors, which will affect the entry and exit of materials and the development of storage work to a certain extent, thereby limiting the overall warehouse management level. Summary of the invention

[0006] The present application provides a warehouse cargo door management system and a processing method thereof, which are used to create a novel warehouse cargo door management mechanism. It is based on PLC equipment and OPC communication, and provides OPC clients with a remote, visual warehouse cargo door control solution. This helps to efficiently carry out the entry and exit and storage of goods, improve the warehouse management level including management efficiency and management accuracy, and promote a more efficient and intelligent warehouse management effect in practical applications.

[0007] In a first aspect, the present application provides a warehouse cargo door management system, which includes multiple PLC devices, an OPC server and an OPC client. The multiple PLC devices are deployed at the warehouse site and connected to corresponding control devices of different warehouse cargo doors. The OPC server and the OPC client communicate based on the OPC protocol.

[0008] A plurality of PLC devices collect first door opening and closing status data of cargo doors of different warehouses, and report the first door opening and closing status data to an OPC server, wherein sensors are used to monitor the door opening and closing status of cargo doors of warehouses;

[0009] The OPC server converts the first door opening and closing status data into second door opening and closing status data, and sends the second door opening and closing status data to the OPC client;

[0010] Based on the second status data, the OPC client displays the open and close status of cargo doors in different warehouses through a visual interface pre-configured for the warehouse site;

[0013] In combination with the first aspect of the present application, in a first possible implementation method of the first aspect of the present application, before the OPC server converts the first door opening and closing control instruction into the second door opening and closing control instruction and sends the second door opening and closing control instruction to the target PLC device, the OPC server also determines whether the corresponding user who reports the first door opening and closing control instruction has control authority. If so, it triggers the conversion of the first door opening and closing control instruction into the second door opening and closing control instruction, and sends the second door opening and closing control instruction to the target PLC device.

[0020] In combination with the first aspect of the present application, in the seventh possible implementation method of the first aspect of the present application, the OPC server determines the corresponding cargo door opening time point, cargo door closing time point, cargo entry and exit times and cargo entry and exit duration based on the door opening and closing status data within the monitoring time period, and then carries out the corresponding warehouse cargo door allocation work analysis and processing, and pushes the analysis results to the OPC client for the OPC client to display through a visual interface.

[0021] In a second aspect, the present application provides a processing method for a warehouse cargo door management system. The processing method for the warehouse cargo door management system is applied to the warehouse cargo door management system. The warehouse cargo door management system includes multiple PLC devices, an OPC server, and an OPC client. The multiple PLC devices are deployed at the warehouse site and connected to the corresponding control devices of different warehouse cargo doors. The OPC server and the OPC client communicate based on the OPC protocol. The processing method for the warehouse cargo door management system includes:

[0022] Multiple PLC devices collect the door opening and closing status data of different warehouse cargo doors, and report the first door opening and closing status data to the OPC server, wherein the sensor is used to monitor the door opening and closing status of the warehouse cargo door;

[0023] The OPC server converts the first door opening and closing status data into second door opening and closing status data, and sends the second door opening and closing status data to the OPC client;

[0024] Based on the second door opening and closing status data, the OPC client displays the door opening and closing status of different warehouse cargo doors through a visual interface pre-configured for the warehouse site;

[0025] The OPC client receives the first door opening and closing control instruction entered for the cargo door of the target warehouse through the visual interface, and reports the first door opening and closing control instruction to the OPC server;

[0026] The OPC server converts the first door opening and closing control instruction into a second door opening and closing control instruction, and sends the second door opening and closing control instruction to the target PLC device, so that the second PLC device switches the door opening and closing state of the target warehouse cargo door through the target control device of the target warehouse cargo door.

[0029] In combination with the second aspect of the present application, in a second possible implementation of the second aspect of the present application, the warehouse cargo door management system is also configured with a database, which stores recorded data of the system operation process for query and backtracking.

[0030] In combination with the second aspect of the present application, in a third possible implementation manner of the second aspect of the present application, the method further includes:

[0031] When a certain PLC device determines that a corresponding warehouse cargo door has an abnormal fault condition based on the collected first door opening and closing status data, an early warning signal is sent through an on-site early warning device or to an OPC server.

[0032] In combination with the second aspect of the present application, in a fourth possible implementation manner of the second aspect of the present application, the method further includes:

[0033] When a PLC device receives a manual trigger control instruction through an on-site configured operating device, it controls the opening and closing status of the corresponding warehouse cargo door.

[0034] In combination with the second aspect of the present application, in a fifth possible implementation manner of the second aspect of the present application, the method further includes:

[0035] When a PLC device senses that there are goods to be passed through the cargo door through the corresponding sensor configured on site, it generates autonomous control instructions according to the preset door opening and closing autonomous control strategy to control the opening and closing status of the corresponding warehouse cargo door so that the goods to be passed can pass through the cargo door.

[0036] In combination with the fifth possible implementation of the second aspect of the present application, in a sixth possible implementation of the second aspect of the present application, the PLC device is specifically configured as follows:

[0037] When it is detected that the cargo at the cargo door position has specific cargo shape features, specific image identification or specific sensing signals, it is determined that there is cargo to be passed.

[0038] In combination with the second aspect of the present application, in a seventh possible implementation manner of the second aspect of the present application, the method further includes:

[0039] Based on the door opening and closing status data within the monitoring time period, the OPC server determines the corresponding cargo door opening time, cargo door closing time, cargo entry and exit times, and cargo entry and exit duration, and then carries out the corresponding warehouse cargo door allocation work analysis and processing, and pushes the analysis results to the OPC client for display through the OPC client through a visual interface.

[0050] First, see Figure 1 A schematic diagram of the system architecture of the warehouse cargo door management system of the present application is shown in FIG. Figure 1 As shown, the warehouse cargo door management system provided by the present application may specifically include three parts: multiple PLC devices, OPC servers and OPC clients, among which:

[0051] Multiple PLC devices are deployed at the warehouse site and connected to the corresponding control devices of different warehouse cargo doors, so that the opening and closing states of the warehouse cargo doors can be controlled by the control devices. Among them, PLC, namely Programmable Logic Controller, is a programmable logic controller.

[0052] OPC server and OPC client involve B / S architecture or C / S architecture. The server and client communicate based on the OPC protocol. OPC stands for Object Linking and Embedding for Process Control.

[0053] For OPC servers, you can also combine Figure 2 and Figure 3 The scenario schematic diagrams of the OPC server of the present application are shown separately for further understanding.

[0054] It should be noted that the application scenario involved in the present application scheme is specifically a warehouse cargo door management scenario, which is particularly suitable for application scenarios such as enterprise production where there is a potential need for management of large warehouses / numerous warehouse cargo doors.

[0055] As for the potential management needs mentioned here, it is understandable that the inventors of the present application have found that although manufacturing companies have generally established corresponding management systems to uniformly manage warehouse materials, they usually focus on recording the storage status of materials in online systems and often ignore the management of warehouse cargo doors, which will affect the entry and exit of materials and the development of storage work to a certain extent, and thus limit the overall warehouse management level. Therefore, the management needs that this application focuses on to improve the warehouse cargo door management level are called potential management needs.

[0056] Next, based on the above brief content, combined with the specific work content of the warehouse cargo door management system of this application, we will have a more specific understanding of the warehouse cargo door management system provided by this application:

[0057] (1) A plurality of PLC devices collect first door opening and closing status data of cargo doors of different warehouses, and report the first door opening and closing status data to an OPC server, wherein sensors are used to monitor the door opening and closing status of cargo doors of warehouses;

[0058] For warehouse cargo doors, different types of sensors such as position sensors (which can be divided into contact sensors and proximity sensors) can be configured to determine whether the warehouse cargo door is in an open state, a closed state, a state from open to closed, or a state from closed to open in its working state.

[0059] For the convenience of explanation, the door opening and closing control status collected here is recorded as the first door opening and closing status data, and the door opening and closing status data involved subsequently is recorded as the second door opening and closing status data. In addition, the door opening and closing control instructions involved subsequently are also distinguished by the first and second.

[0060] It can be understood that, in actual situations, the PLC equipment collects the opening and closing status data of the warehouse cargo door through the corresponding sensors and controls the opening and closing status of the warehouse cargo door through the corresponding control device (involving the corresponding mechanical structure). This is a relatively mature technology in this field, so it will not be explained in detail here. Of course, in actual situations, the possibility of adopting improved and optimized technologies or even self-developed novel technologies is not ruled out.

[0061] After the multiple PLCs have each collected the door opening and closing status data representing the door opening and closing status of the corresponding warehouse cargo doors in real time, they can upload it to the OPC server for further processing.

[0062] The communication between the PLC device and the outside world may involve different types of communication methods such as RS232, Ethernet or text files, and may also involve the interface configuration work of the data communication module of the PLC device in advance.

[0063] As an example, for an RS232 interface, the interface configuration contents may include port number, baud rate, data bit, stop bit and parity bit; for an Ethernet interface, the interface configuration contents may include IP, port number and communication protocol; for a file interface, the interface configuration contents may include access path, folder name, access user name and password.

[0064] (2) The OPC server converts the first door opening and closing status data into second door opening and closing status data, and sends the second door opening and closing status data to the OPC client;

[0065] It can be understood that the present application introduces a visual warehouse cargo door opening and closing status control setting for the client side. Therefore, in response to the data usage requirements of the application client, the OPC server needs to convert the opening and closing door status data reported by the PLC device in real time into a data format that can be transmitted through the OPC protocol and is easy for the OPC client to use. For this, the corresponding data format conversion processing can be carried out to convert it into a second opening and closing door status data, and then sent to the OPC client based on the pre-configured OPC protocol or OPC communication method.

[0066] It can be understood that the OPC client corresponds to the user side. In actual situations, there can be one or more OPC clients. The OPC server can also be configured as one or more OPC servers according to the performance requirements or deployment requirements of the server.

[0067] Among them, the OPC client can specifically be different types of devices such as smart phones, tablet computers, desktop computers, all-in-one computers, personal digital assistants (PDA), etc., and is equipped with the client application involved in this application.

[0068] (3) Based on the second door opening and closing status data, the OPC client displays the door opening and closing status of different warehouse cargo doors through a visualization interface pre-configured for the warehouse site;

[0069] It can be understood that under the visual warehouse cargo door opening and closing status control setting introduced in the present application, the OPC client is designed with a specially set visualization interface, in which the opening and closing status of different warehouse cargo doors on site are vividly displayed, and can be dynamically updated based on the second opening and closing status data sent by the OPC server, so that users on the OPC client side can easily and intuitively understand the opening and closing status of each warehouse cargo door.

[0070] In the visualization interface, in addition to using cargo door labels or location labels to indicate which warehouse cargo door on site the warehouse cargo door displayed in the interface is, you can also use a 3D environmental model or digital twin model (created using environmental data collected from the actual site environment) based on the actual site environment to display the opening and closing status of each warehouse cargo door in a more three-dimensional and realistic manner, further improving visualization and enhancing user experience.

[0071] (4) The OPC client receives the first door opening and closing control instruction entered for the cargo door of the target warehouse through the visual interface, and reports the first door opening and closing control instruction to the OPC server;

[0072] It can be understood that the visualization interface configured in the present application, in addition to displaying the opening and closing door status of each warehouse cargo door, can also be configured with a control function. On the basis of presenting the opening and closing door status collected by the back end to the user in the form of an open and close on the front end in this visualization interface, the user can enter the corresponding first opening and closing door control instruction based on the user's needs to control the opening and closing door status of a specific warehouse cargo door.

[0073] Specifically, in the visualization interface, the icon / graphic of the warehouse cargo door itself can be configured with a touch component to receive door opening and closing control instructions; or, a touch button can be configured within a preset distance of the icon / graphic of the warehouse cargo door itself to receive door opening and closing control instructions; or, the visualization interface can also be provided with door opening and closing setting buttons on the bottom bar, side bar, and top bar to initiate the task of setting the door opening and closing control status, and allow the user to directly input the cargo door identification or position identification of the target warehouse cargo door for which the door opening and closing control status needs to be set, or the user can further select the icon / graphic of the target warehouse cargo door for which the door opening and closing control status needs to be set in the interface, so as to determine the specific target warehouse cargo door for which the door opening and closing control status needs to be controlled.

[0074] After converting the user operation into the corresponding first door opening and closing control instruction, the OPC client can report it to the OPC server to promote further door opening and closing status control processing on the system.

[0075] In addition, the OPC client can also be configured with a file output function to meet the needs of users to obtain on-site conditions in the form of offline files.

[0076] For example, the OPC client can specify the settings of the corresponding file types and data items for different device models: select the output file type (XML, TXT, EXCEL, etc.), define the output data item name, data type, and data length information. Specifically, the file output content can be defined as shown in Table 1 below:

[0077] Table 1 - Example of file output content

[0078] Data Item Data Types Data length illustrate PLCNO VARCHAR 20 PCL device number STATUS VARCHAR 10 Current Status DENSITY NUMBER 10,4 density WIDTH NUMBER 10,4 width NUMBER NUMBER 10,4 Number of pieces WEIGHT NUMBER 10,4 weight THICKNESS NUMBER 10,4 thickness UPDATETIME NUMBER 10,4 Update time SYSTEM NUMBER 10,4 System EQUSTATUS NUMBER 10,4 Physical status of the device OPERATOR VARCHAR 20 Operator

[0079] (5) The OPC server converts the first door opening and closing control instruction into a second door opening and closing control instruction, and sends the second door opening and closing control instruction to the target PLC device, so that the second PLC device switches the door opening and closing state of the target warehouse cargo door through the target control device of the target warehouse cargo door.

[0080] Similar to the previous conversion of the first door opening and closing status data into the second door opening and closing control instruction adapted to the OPC client, after the OPC server obtains the first door opening and closing control instruction, it can convert it into the second door opening and closing control instruction adapted to the target PLC device.

[0081] In this way, after the target PLC device receives the second door opening and closing control instruction, it can determine the specific warehouse cargo door to be controlled, and switch / maintain its door opening and closing state to the door opening and closing control state to be set.

[0082] from Figure 1It can be seen from the illustrated embodiments that, in view of the warehouse management objectives, the present application has created a novel warehouse cargo door management mechanism, which is based on PLC equipment and OPC communication, and provides remote, visual warehouse cargo door control solutions for OPC clients. This helps to efficiently carry out the entry and exit and storage of goods, improve the warehouse management level including management efficiency and management accuracy, and promote more efficient and intelligent warehouse management effects in practical applications.

[0083] Next, continue with the above Figure 1 The possible implementation methods of the illustrated embodiment in practical applications are described in detail.

[0084] As an exemplary embodiment, the present application scheme may also involve a user authority verification mechanism in real time. Further control processing of on-site equipment will be promoted only after passing the verification to ensure that the user has sufficient authority to control the on-site PLC equipment and its warehouse cargo door. While ensuring data / equipment security, it also helps to achieve more flexible warehouse cargo door control effects through multi-level user authority settings.

[0085] Specifically, before the OPC server converts the first door opening and closing control instruction into the second door opening and closing control instruction and sends the second door opening and closing control instruction to the target PLC device, the OPC server can also determine whether the corresponding user who reports the first door opening and closing control instruction has control authority. If so, it triggers the conversion of the first door opening and closing control instruction into the second door opening and closing control instruction, and sends the second door opening and closing control instruction to the target PLC device.

[0086] Among them, the first door opening and closing control instruction can directly carry the authority identifier of the corresponding user who initiated the instruction, such as the authority identifier that directly identifies the authority, or it can also carry an identifier such as a user ID or device ID that indirectly identifies the authority, so that the OPC server can query the corresponding user authority. This is all possible.

[0087] In addition, as another exemplary embodiment, the warehouse cargo door management system of the present application may also be configured with a database, which stores recorded data of the system operation process for query and backtracking.

[0088] The database can be a dedicated database device or installed in the form of a database service on the enterprise's original equipment or OPC server. The database type or database product involved can be Oracle, SQLServer or DB2, etc. During the database operation, the data records in the operation process can be saved to the specified address / storage space. In this way, when there is a corresponding data query or event backtracking in the future, the data can be provided for response processing to meet the diversified data usage needs.

[0089] Furthermore, for the PLC equipment on site, it can also be configured with an early warning mechanism so that when an abnormal situation occurs in the warehouse cargo door and the door opening and closing status control requirements cannot be met normally, an early warning will be issued on site or to the rear to prompt relevant personnel to respond in time, check the fault, and arrange to deal with the fault or evacuate to avoid further adverse effects and avoid the occurrence of material damage accidents or personal safety accidents.

[0090] In this regard, as another exemplary embodiment, when a certain PLC device determines that a corresponding warehouse cargo door has an abnormal fault condition based on the collected first door opening and closing status data, an early warning signal is sent through an on-site early warning device or to an OPC server.

[0091] Among them, it can be understood that the on-site early warning device can mainly achieve the purpose of outputting early warning on-site through the speaker / loudspeaker; to issue an early warning to the rear, it can send an early warning signal to the OPC server, prompting the OPC server to inform the corresponding users in accordance with the preset early warning strategy / rules through AI phone, system pop-up window, email or text message, etc., or send an early warning instruction to the OPC client, so as to prompt the OPC client to inform the user in front of the client through system pop-up window, etc.

[0092] In addition, the warehouse cargo door management system of the present application can also be configured with a manual control function for the door opening and closing status, so as to meet the needs of on-site users to manually switch the door opening and closing status of the warehouse cargo door without going through the OPC client.

[0093] In this regard, as another exemplary embodiment, when a certain PLC device receives a manual trigger control instruction through an operating device configured on site, it controls the opening and closing state of the corresponding warehouse cargo door.

[0094] Among them, the operating device is connected to the PLC equipment, and can be a related button device deployed on the wall, desktop and other locations, or it can be a field device with a command input function (the device can have buttons, or realize command input through input devices such as touch screens).

[0095] It can be understood that the manual control function involved in the embodiment here can not only meet the user needs of on-site users for normal use of the warehouse cargo door under actual circumstances, but also serve as a backup function, so that in some special circumstances, the opening and closing status of the warehouse cargo door can be manually and quickly controlled on-site to ensure the safety of materials and personnel.

[0096] At the same time, the warehouse cargo door management system of the present application can also be configured with an autonomous control function of the door opening and closing status, that is, an automatic sensing function, which obtains input data by monitoring the conditional variables of the warehouse cargo door, and combines this with the pre-configured door opening and closing status autonomous control strategy / rules to determine whether to switch the door opening and closing status. In actual applications, in some targeted cases, an intelligent door opening and closing status control effect is achieved to meet the unmanned door opening and closing status switching effect in special application scenarios.

[0097] Specifically, as another exemplary embodiment, when a PLC device senses that there are goods to be passed through the cargo door position through a corresponding sensor configured on site, it generates an autonomous control instruction according to a preset door opening and closing autonomous control strategy to control the door opening and closing status of the corresponding warehouse cargo door so that the goods to be passed can pass through the cargo door.

[0098] It can be understood that the PLC device can determine whether there are goods to be passed through the cargo door position of the warehouse through data collected by some sensors that can collect the first door opening and closing status data, or through data collected by sensors other than the sensors that collect the first door opening and closing status data. If so, it can trigger the execution of the preset door opening and closing autonomous control strategy, and perform further autonomous control instruction generation processing to generate control instructions required to be executed by the control device, control the door opening and closing status of the warehouse cargo door, and allow the currently identified goods to be passed through the warehouse cargo door.

[0099] Among them, it should be noted that, for the generation target of autonomous control instructions, two layers of processing are involved in the embodiment here. The first layer is to determine whether there are goods to be passed, and the second layer is to choose how to generate autonomous control instructions or what kind of autonomous control instructions to generate through the preset door opening and closing autonomous control strategy. In this way, for the goods to be passed through the warehouse door, not only is there no need for manual intervention and the work efficiency is greatly improved, but it can also bring a highly adaptable intelligent control effect of the door opening and closing status.

[0100] Among them, for determining whether there is data of goods to be passed, as another exemplary embodiment, the PLC device can be specifically configured as follows:

[0101] When it is detected that the cargo at the cargo door position has specific cargo shape features, specific image identification or specific sensing signals, it is determined that there is cargo to be passed.

[0102] It can be understood that the specific cargo shape features and specific image identification mean that the sensor involved is specifically an image sensor. The PLC device needs to perform image recognition processing on the collected image data based on its own data processing capabilities or the data processing capabilities of the connected device to determine whether there are specific cargo shape features or specific image identification in the field of view, wherein the image identification is not related to the overall outline / appearance shape of the cargo to be passed, and corresponds to the image identification drawn on the surface of the cargo to be passed itself or the image identification drawn by a marker affixed to the surface of the cargo.

[0103] The specific sensing device means that the sensor involved can be a sensing device of the type such as an RFID electronic tag or a Bluetooth module related to a preset sensing method. In this way, if a specific sensing signal is collected, it can be determined that there are goods to be passed in the current situation.

[0104] In addition, it can be understood that in actual applications, in order to determine whether there are specific cargo shape features, specific image identifications or specific sensing signals of the cargo to be passed, in addition to being preset, that is, relatively fixed, it can also be dynamically / real-time updated.

[0105] Specifically, these three can be issued by the OPC server, and the OPC server can be entered by the user through the OPC client, or directly configured on the server.

[0106] In addition, the OPC server can also autonomously generate / determine specific cargo shape features, specific image identification or specific sensing signals used to determine whether there are cargo to be passed. Specifically, when the OPC server extracts the autonomous passing task generated by the user / system or receives the autonomous passing task forwarded by other devices, it can retrieve the task content including the cargo image and cargo description (such as appearance shape, size specifications and product model, etc.), so as to extract the key data that can be used to generate / determine the corresponding specific cargo shape features, specific image identification or specific sensing signals, and then carry out the specific generation / determination processing.

[0107] In addition, while autonomously controlling the open and closed status of warehouse cargo doors, the OPC server can also predict the required cargo passage time, which can also be predicted based on the corresponding appearance shape, size specifications and product model.

[0108] Further corrections can be made based on the cargo passage conditions of specific warehouse cargo doors (represented by indicators such as cargo passage efficiency and cargo passage abnormality rate). That is to say, even for the same warehouse cargo door, due to differences in the actual cargo passage conditions, the final determined cargo passage time will also be different, thereby further improving the adaptability of the given cargo passage time.

[0109] It can be understood that for the cargo door of the same warehouse, the above settings are handled at the overall level. In addition, based on the same warehouse cargo door, further corrections can be made based on the specific cargo passage conditions of different types of cargo. In this way, a deeper correction effect of the cargo passage time can be achieved in details, and a more intelligent autonomous control effect of the door opening and closing status can be achieved.

[0110] It should be noted that the above settings are based on the solution direction of matching different types or granularities of goods to be passed with different goods passing through. In this way, a high-precision prediction effect of the goods passing time is achieved, which helps to meet the goods passing needs for different goods to be passed under different circumstances, and can also avoid safety hazards caused by too much or too little automatic door opening / closing time.

[0111] In addition, regarding the safety of warehouse cargo doors, in actual applications, a detection mechanism is usually provided for foreign objects that are stuck or on the closing trajectory of the cargo door, so as to issue an early warning or suspend work when foreign objects are present, thereby ensuring the safety of materials and personnel.

[0112] In addition, for the warehouse cargo door management system, corresponding system work status statistics functions can also be configured to correspond to system management needs, and the system work process can be recorded, such as the application of the database mentioned above, and further statistical analysis and processing can be performed on the basis of the recorded data according to the preset statistical analysis requirements to obtain statistical analysis results that can be displayed, for example, they can be conveniently displayed through the visual interface of the OPC client side.

[0113] Correspondingly, as another exemplary embodiment, the OPC server can determine the corresponding cargo door opening time point, cargo door closing time point, cargo entry and exit times and cargo entry and exit duration based on the door opening and closing status data within the monitoring time period, and then carry out the corresponding warehouse cargo door allocation work analysis and processing, and push the analysis results to the OPC client for the OPC client to display through a visual interface.

[0114] It can be understood that in the embodiment here, a specific implementation plan is provided for the specific indicators involved in the statistical / quantification system working conditions, so that specific statistical analysis and processing can be carried out according to the statistical analysis requirements and indicators such as abnormality rate, growth rate or stability, so that the OPC client side can intuitively display and process to the user based on the visual interface, so that the user can make further decision-making analysis, analyze operational efficiency, optimize the management of goods in and out, strengthen the management effect of warehouse cargo doors, and then strengthen the overall management effect of the warehouse, so as to achieve more efficient, stable and safe warehouse scheduling and play a good closed-loop management role.
