[0042] The core of this application is to provide a method, device, server, and computer-readable storage medium for acquiring source-tracing videos, thereby improving the efficiency of acquiring source-tracing videos.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] In existing technologies, warehouse traceability systems are typically implemented by connecting a cloud platform with the customer's warehouse management system through an open platform. Data is transmitted to the cloud platform to enable video traceability of processes such as warehouse packaging, inspection, and outbound shipment (i.e., viewing playback of each order). However, each device needs to connect to the cloud platform, which is costly, cumbersome, and reduces the efficiency of obtaining traceability videos.

[0045] Therefore, this application provides a method for obtaining traceability videos. When a barcode scanning device scans a barcode, the scanning data of the scanning device is directly intercepted and encapsulated into a video request instruction, which is then sent to a cloud platform. The cloud platform directly obtains the corresponding traceability video based on the instruction. This method does not require reconfiguration when applied to different devices, avoiding the need for re-interconnection due to different devices and improving the efficiency of obtaining traceability videos.

[0046] The following embodiment illustrates a method for obtaining source-tracing videos provided in this application.

[0047] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a method for obtaining source-tracing videos provided in an embodiment of this application.

[0048] In this embodiment, the method may include:

[0049] S101, in response to the scanning command of the barcode scanner, intercepts the scanning record of the barcode scanner;

[0050] This step aims to intercept the scanning records of the barcode scanner in response to the scanning command of the barcode scanner.

[0051] The scanning device refers to the device used in the management process. In other words, when the scanning device scans a code, its data is intercepted and recorded as a scan record. This means that by intercepting the data, the scanned data is directly obtained, avoiding the need for interfacing and adapting with different devices. Specifically, the scanning device can be a barcode scanner, and the scanning objects include, but are not limited to, barcodes and QR codes.

[0052] Furthermore, this embodiment may also include:

[0053] Step 1: Configure the parameters of the barcode scanner based on the received configuration parameters;

[0054] Step 2: Obtain the configuration parameters of the scanning device and add the configuration parameters to the video request command.

[0055] As can be seen, this optional solution mainly describes how the configuration parameters of the scanning device can also be obtained. In this optional solution, the scanning device is configured based on the received configuration parameters; the configuration parameters of the scanning device are obtained and added to the video request command. Therefore, the cloud platform can also obtain the corresponding configuration parameters through the video request command. These configuration parameters include: the target enterprise, the target store, and the target scanning device corresponding to the target operating console.

[0056] Furthermore, this step may include:

[0057] Intercept the data input from the barcode scanning device and record it as a scan log. The scan log includes at least one of the following: barcode data, scan time, upload time, and scan status.

[0058] As can be seen, the scan record in this optional solution includes at least one of the following: barcode data, scan time, upload time, and scan status.

[0059] Furthermore, the process of intercepting data in the previous alternative solution may include:

[0060] Step 1: Obtain device information of the barcode scanning device through bus enumeration;

[0061] Step 2: Intercept the behavior data of the scanning device and encapsulate the behavior data into a data packet and send it to the local device so that the local device can parse the scanning record from the data packet.

[0062] As can be seen, this optional solution mainly describes how to intercept scan records. In this optional solution, the device information of the barcode scanning device is obtained through bus enumeration; the behavioral data of the barcode scanning device is intercepted, and the behavioral data is encapsulated into data packets and sent to the local device so that the local device can parse the scan record from the data packets.

[0063] Furthermore, this step may also include:

[0064] The scan records are stored in a local database and then uploaded to a cloud device.

[0065] As can be seen, this optional solution also allows the scan records to be stored in a local database and uploaded to a cloud device.

[0066] S102, encapsulate the scanned record into a video request instruction based on a preset format;

[0067] Building upon S101, this step aims to encapsulate the scanned records into a video request instruction based on a preset format.

[0068] The preset format can be a format set by technicians as needed, or it can be other network transmission formats provided in the existing technology; no specific limitation is made here.

[0069] Furthermore, this step may include:

[0070] The scanned records are encapsulated into video request commands based on network data transmission protocols.

[0071] As can be seen, this optional solution mainly encapsulates the scan records into video request instructions based on network data transmission protocols.

[0072] S103, send the video request instruction to the cloud management platform so that the cloud management platform can obtain the corresponding video within the target time period based on the scan record in the video request instruction and save it as the source video.

[0073] Building upon step S102, this step aims to send a video request command to the cloud management platform. This allows the cloud management platform to retrieve the corresponding video within the target time period based on the scan records in the video request command and save it as the source-tracing video. In other words, the cloud management platform directly obtains the corresponding source-tracing video from the video source using the parameters in the corresponding video request command, thus achieving video source tracing.

[0074] Furthermore, the process of acquiring the video in this step may include:

[0075] Step 1: The cloud management platform parses the video request command to obtain the command parameters;

[0076] Step 2: Acquire the video recording from the target camera device. Based on the command parameters, acquire the video from the target camera device to obtain the source video and save it.

[0077] As can be seen, this optional solution mainly describes how to obtain the traceability video. In this optional solution, the cloud management platform parses the video request command to obtain the command parameters; it acquires the recording of the target camera device, and based on the command parameters, it acquires the video from the target camera device to obtain the traceability video, which is then saved. In this optional solution, the target camera device and the barcode scanning device are deployed in the same working environment, and the recording of the target camera device can be a video stream containing the operation of the barcode scanning device.

[0078] In summary, this embodiment intercepts the scanning data of the scanning device when it scans a code and encapsulates it into a video request command, which is then sent to the cloud platform. The cloud platform directly obtains the corresponding traceability video based on the command. This eliminates the need for reconfiguration when applied to different devices, avoiding the need for re-interconnection due to different devices and improving the efficiency of obtaining traceability videos.

[0079] The following specific embodiment further illustrates a method for obtaining source-tracing videos provided in this application.

[0080] Please refer to Figure 2 , Figure 2 A flowchart illustrating another method for obtaining traceable videos provided in this application embodiment.

[0081] In this embodiment, the method may include:

[0082] Step 201: Receive the encapsulated interface request instruction sent by the self-developed client;

[0083] Specifically, the interface request instruction includes: scan data, console ID, scan time, event name, event type, and warehouse ID;

[0084] Furthermore, before performing step 201, the following may also be included:

[0085] Step 203: Configure the target scanning devices corresponding to the target enterprise, target store, and target workstation;

[0086] Step 204: Save and scan the target barcode scanning device data; upon receiving the barcode scanned by the barcode scanning device, generate a scanning record, which includes barcode data, scanning time, upload time, and status;

[0087] Step 205: Encapsulate the data in the scan record into an interface request instruction according to preset rules, and push the data to the cloud platform (specifically, store the intercepted data in the local database and upload it to the cloud through the interface).

[0088] Specifically, the process of intercepting QR code scanning data by the self-developed QR code scanning device client may include:

[0089] Step 1: Intercepting USB device (i.e., barcode scanning device) insertion;

[0090] Step 2: USB bus enumeration to obtain detailed device information;

[0091] Step 3: Intercept certain behaviors of the specified device, encapsulate the device's behaviors according to the pcap packet (Pcap is an abbreviation for Packet Capture, an industry-standard network packet capture format) protocol, and send them to the local machine;

[0092] Step 4: Parse the protocol layer by layer to obtain the required data (such as barcode data, scan time, upload time, status, etc.);

[0093] Step 5: Store the intercepted data in the local database and upload it to the cloud platform via the interface.

[0094] Step 202: Parse the command parameters, the cloud platform obtains the recordings of the target IPC (IP CAMERA, network camera), and generates the recorded video within the target time period based on the parameters.

[0095] Specifically, the cloud platform generates recorded videos for the corresponding time period based on the input parameters.

[0096] The traceability types supported in this embodiment include, but are not limited to: after data interception, request instructions for different traceability types are encapsulated according to the interception tool and transmitted to the cloud platform to generate target recordings. Morning meetings are one type of event, and events can have countless types. Among them, those that can be traced via video can include three main categories: cashier, warehousing, and events. Through the scanning device client, data can be transmitted to these three main traceability categories and any sub-category within an event, enabling traceability of each event. Data interception is not limited to directly acquiring data through peripherals such as scanning devices, processing it, and then encapsulating it for interception; it can also include forms such as RFID and acquiring user-configured data.

[0097] As can be seen, by encapsulating interface request commands through a self-developed data interception tool, the video traceability function on the cloud platform is realized. This enables the direct acquisition of warehouse data and its uploading to the cloud platform without going through a third-party management system, achieving order video traceability. This eliminates the hassle of different users needing to develop additional functions and implement data integration on top of their own warehouse management system (WMS) when they want to perform video traceability. In other words, it bypasses the WMS system, capturing the barcode scanning actions of warehouse personnel (during packing, inspection, and outbound shipments) in a certain way, parsing the barcode data, transmitting the data to the system through the cloud platform, and combining it with the playback capabilities of IPC to achieve warehouse traceability.

[0098] In this way, skipping the WMS system enables warehouse traceability without affecting the WMS system's own use of data.

[0099] In addition, any brand and model of barcode scanning device can be used, and data interception peripherals can be customized or added, or it can be used in conjunction with other data interception methods to achieve video tracing.

[0100] As can be seen, this embodiment intercepts the scanning data of the scanning device when it scans the code, encapsulates it into a video request command, and sends it to the cloud platform. The cloud platform directly obtains the corresponding traceability video based on the command. When applied to different devices, it does not need to be reconfigured, avoiding the need for re-interconnection due to different devices and improving the efficiency of obtaining traceability videos.
