[0003] However, vending machines are usually distributed in various places with complex network environments. When preparing for upgrades, network signals may be unstable, interrupted, or the network bandwidth may be insufficient. This leads to poor stability, which causes the vending machines to be unable to communicate normally with the server and obtain upgrade files or instructions, hindering the upgrade process.

[0023] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present disclosure. However, it will be apparent to those skilled in the art that the present disclosure may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present disclosure with unnecessary detail.

[0024] In order to make the purpose, technical solutions and advantages of the present disclosure more clear, specific embodiments will be described below with reference to the accompanying drawings.

[0025] Please refer to Figure 1 , Figure 1 This is a flow chart of an intelligent remote upgrade method provided by an embodiment of the present disclosure. The method may include S101 to S103.

[0026] S101: Determine the location information and device status score of the target device based on the heartbeat packet of the target device, and determine a target upgrade mode based on the location information and device status score of the target device.

[0027] In this embodiment, before determining the location information and device status score of the target device based on the heartbeat packet of the target device, the following steps are further included:

[0028] Based on the version upgrade instruction and the device information library, a version check instruction is sent to all target devices in the target area.

[0029] The version check instruction is used to instruct all target devices in the target area to send heartbeat packets to the remote server.

[0030] In this embodiment, a version upgrade instruction, initiated by a remote server, triggers the version check and upgrade process for devices in a target region. The version upgrade instruction may include the version number and a description of the upgrade content. The device information database stores information related to all vending machines in the target region, including basic device information and status information. The target region is a designated geographic area encompassing the range of devices requiring version checks and upgrades. The targeted upgrade mode determines the upgrade method based on the target device's location information and device status score.

[0031] After the remote server prepares the upgrade package and confirms the upgrade, it generates a version check instruction and sends it to all target devices in the target region, instructing them to perform a version check. A heartbeat packet is a data packet sent by a target device to the remote server to indicate its online status. This packet can include information such as the device's location, status, network environment, and current version number. The device status score is used to assess the device's health and upgrade feasibility. The score can be calculated based on factors such as hardware performance, network stability, battery charge, and idle status.

[0032] In this embodiment, after receiving the version upgrade instruction, the remote server filters all target devices in the target area from the device information database. The remote server sends a version check instruction to all target devices in the target area. After receiving the version check instruction, the target device sends a heartbeat packet containing the device's location information, status information, and current version number to the remote server. The remote server parses the received heartbeat packet to determine the device's location information and calculates a device status score based on the device's status information. Based on the target device's location information and device status score, the remote server selects an appropriate target upgrade mode. Based on the target upgrade mode, the remote server sends the corresponding upgrade instruction and upgrade package to the target device or edge server to complete the device upgrade.

[0033] S102: If the target upgrade mode is the first upgrade mode, a first device upgrade instruction and an upgrade package are sent to the target device. The first device upgrade instruction is used to instruct the target device to upgrade using the upgrade package.

[0034] In this embodiment, the first upgrade mode is a direct upgrade, suitable for situations where the device is in good condition and the network environment is stable. The first device upgrade instruction is sent by the remote server to the target device and is used to trigger the device to initiate the upgrade operation. The first device upgrade instruction may include the version number of the upgrade package, the specific upgrade steps, and the upgrade time requirement. The upgrade package refers to the collection of files for the new version of the target device's software or system, including code files and configuration files. Parameters may include the upgrade package size and a checksum, which is used to ensure that the upgrade package is not damaged during transmission.

[0035] For example, based on the target device's location information and device status score, the remote server determines that the first upgrade mode is appropriate. The remote server generates a first device upgrade instruction and prepares a corresponding upgrade package. The first device upgrade instruction specifies the detailed upgrade process for the target device. The remote server sends the first device upgrade instruction and upgrade package to the target device. During this transmission process, an appropriate transmission protocol is used to ensure data integrity and accuracy.

[0036] After receiving the instruction and upgrade package, the target device will verify the verification code of the upgrade package, and then use the upgrade package to upgrade itself according to the requirements in the first device upgrade instruction, such as overwriting old files, updating system configuration, etc. After the upgrade is completed, it will perform self-check and restart.

[0037] S103: If the target upgrade mode is the second upgrade mode, a second device upgrade instruction and the upgrade package are sent to the edge server. The second device upgrade instruction instructs the edge server to process the upgrade package into blocks to obtain multiple upgrade block files, and further instructs the edge server to send the second device upgrade instruction and the multiple upgrade block files to the target device. The second device upgrade instruction also instructs the target device to upgrade using the multiple upgrade block files.

[0038] In this embodiment, sending the second device upgrade instruction and upgrade package to the edge server includes:

[0039] An edge server corresponding to the target device is determined based on the location information of the target device.

[0040] The second device upgrade instruction and upgrade package are sent to the edge server corresponding to the target device.

[0041] In this embodiment, the second upgrade mode is an upgrade strategy used when the network environment is poor or the device is unstable. It uses edge servers for block processing, reducing the risk of upgrade package transmission. The second device upgrade instruction may include the upgrade package version number, block size setting, target device unique identifier, upgrade sequence, and operation instructions. Edge servers are network nodes deployed close to the target device, used to offload load from remote servers and optimize data transmission. The upgrade block file may include its own serial number, the upgrade package version number, and data content.

[0042] In this embodiment, the remote server determines that the target device is suitable for the second upgrade mode based on its location information and device status score. Based on the target device's location information, the remote server selects the edge server closest to the target device. The remote server sends the second device upgrade instruction and upgrade package to the edge server. Upon receipt, the edge server divides the upgrade package into blocks based on the second device upgrade instruction, generating multiple upgrade block files. The edge server then sends the second device upgrade instruction and multiple upgrade block files to the target device. Upon receipt, the target device uses these upgrade block files to perform the upgrade according to the upgrade sequence and operation steps specified in the second device upgrade instruction.

[0043] Exemplarily, the remote server can maintain a mapping table between device locations and edge servers. When it is determined that the target device is applicable to the second upgrade mode, the corresponding edge server address is searched in the mapping table based on the target device location information. The remote server uses a network transmission protocol such as TCP to send the second device upgrade instruction and upgrade package to the selected edge server. After receiving the second device upgrade instruction and upgrade package, the edge server parses the block size parameter in the second device upgrade instruction, divides the upgrade package into multiple upgrade block files according to the block size parameter, and numbers each upgrade block file. The edge server sends the second device upgrade instruction and the multiple numbered upgrade block files to the target device. After receiving it, the target device verifies and integrates the upgrade block files according to the upgrade sequence and operation steps in the second device upgrade instruction to complete the upgrade operation.

[0044] As can be seen from the above, obtaining the target device's location information and device status score through heartbeat packets can accurately determine the device's real-time status and environment, providing data support for formulating appropriate upgrade strategies. Determining the target upgrade model based on this information ensures that the upgrade process is more closely aligned with the device's actual needs, avoiding unnecessary upgrade interruptions or failures.

[0045] Furthermore, the introduction of two upgrade modes—direct upgrade and block-based upgrade via edge servers—greatly enhances upgrade flexibility. In the first upgrade mode, the upgrade process is streamlined and efficient. In the second upgrade mode, the transfer and processing by edge servers effectively reduces the burden on remote servers and adapts to scenarios with unstable networks or limited device performance, ensuring smooth transmission of upgrade packages and successful device upgrades. Considering network bandwidth constraints, block-based processing of upgrade packages effectively reduces data transmission pressure.

[0046] In summary, this embodiment not only improves the stability of remote upgrades, but also ensures the smooth operation of equipment such as vending machines through flexible upgrade strategies, reduces maintenance costs, and improves operational efficiency.

[0047] In one embodiment of the present disclosure, determining a target upgrade mode based on location information and a device status score of a target device includes:

[0048] If the location information of the target device belongs to the first area, the target upgrade mode is determined to be the second upgrade mode.

[0049] If the location information of the target device belongs to the second area and the device status score is greater than or equal to the status score threshold, the target upgrade mode is determined to be the first upgrade mode.

[0050] If the location information of the target device belongs to the second area and the device status score is less than the status score threshold, the target upgrade mode is determined to be the second upgrade mode.

[0051] In this embodiment, the first and second regions are pre-determined areas. The first region represents areas with poor network conditions, complex device operating environments, and relatively long distances from remote servers, such as remote mountainous areas or locations with severe signal shielding. The second region represents areas with excellent network conditions, stable device operating conditions, and relatively close distances to remote servers. The status score threshold is a critical value calculated by comprehensively calculating various device performance indicators and is used to determine whether the device's current status meets the requirements for direct upgrade.

[0052] In this embodiment, a smart remote upgrade method further includes: dividing the target area based on the location information and network signal data of all devices in the target area.

[0053] In this embodiment, the target area is divided based on the location information and network signal data of all devices in the target area, including:

[0054] Generate a network signal heat map based on the network signal data of the target area.

[0055] Based on the first step, the target area is divided into multiple grids. The device distribution density matrix is generated based on the number of devices in each grid. Each element in the device distribution density matrix corresponds to the number of devices in a grid.

[0056] The network signal heat map and device distribution density matrix are clustered based on the K-Means clustering algorithm to obtain multiple cluster sets.

[0057] Multiple cluster sets are divided based on a network signal strength threshold and a device density threshold to obtain a first set and a second set. The geographical location area corresponding to the first set is used as the first area, and the geographical location area corresponding to the second set is used as the second area.

[0058] In this embodiment, multiple cluster sets are divided based on the network signal strength threshold and the device density threshold, including:

[0059] Calculate the network signal strength and device density of each cluster set.

[0060] If the network signal strength is greater than or equal to the network signal strength threshold, and the device density is greater than or equal to the device density threshold, the cluster set is divided into a second set, and the remaining cluster sets are divided into the first set.

[0061] In this embodiment, a network signal heat map is a graphic that visually displays the distribution of network signal strength in a target area, with light and dark colors representing signal strength. The first step length is the side length of the grid used to divide the target area. This can be set based on the area of the target area and the desired grid fineness. For example, it can be set to 100 meters in urban areas and 500 meters in suburban areas.

[0062] The device distribution density matrix records the number of devices within each grid in the target area. The network signal strength threshold determines whether a network signal is good or not, and can be set based on the network signal strength required for proper device operation. The device density threshold determines whether a device distribution is dense or not, and can be set based on the actual conditions and business needs of the target area. Multiple clusters can include grids with strong network signals and high device density, strong network signals but low device density, weak network signals and high device density, and weak network signals and low device density.

[0063] For example, there are a large number of vending machines distributed in a certain city, and the operator uses an intelligent remote upgrade method to manage these vending machines.

[0064] By collecting vending machine location information and network signal data, the network signal data is used to generate a network signal heat map. The grid is then divided according to the set first step length to generate a device distribution density matrix. After clustering using the K-Means algorithm, the clusters are divided into the first and second regions based on network signal strength and device density thresholds. For example, a bustling commercial street in a city center, with strong network signals and high device density, would fall into the second region; whereas a remote, older urban area, with weak network signals and sparse device distribution, would fall into the first region.

[0065] When a new vending machine software version is released, the first upgrade mode is used for vending machines located in the second area with a device status score greater than or equal to the status score threshold. This mode directly receives upgrade instructions and packages for a rapid upgrade. For example, a vending machine in a downtown mall with a stable network and well-functioning devices can quickly complete the upgrade. For vending machines located in the first area, or in the second area with a device status score below the threshold, such as those in remote, older urban areas with poor signal quality, the second upgrade mode is used. This mode uses edge servers for block upgrades, ensuring a stable upgrade process, minimizing upgrade failures due to network and device status issues, and ensuring the normal operation of the vending machines.

[0066] This embodiment precisely divides the target area into a first region and a second region, enabling the adoption of appropriate upgrade modes for different network and device environments, improving upgrade efficiency and success rates. Cluster analysis is performed using network signal heat maps and device distribution density matrices, enabling scientific and rational regional divisions, making them more accurate and consistent with actual conditions. This embodiment also flexibly responds to different device states, rapidly upgrading devices in good condition and adopting a robust upgrade strategy for devices in poor condition, effectively ensuring the normal operation of the devices and improving overall management efficiency and user experience.

[0067] In one embodiment of the present disclosure, determining a device status score of a target device based on a heartbeat packet of the target device includes:

[0068] Determine the device resource status and device network status based on the heartbeat packet of the target device.

[0069] The device status score is calculated based on the device resource status, the device network status, and the status score function.

[0070] The state score function is:

[0071]

[0072] Among them, S represents the device status score, 、 Both represent weight coefficients, Indicates the device resource status determined based on the heartbeat packet received at time T. Indicates the device network status determined based on the heartbeat packet received at time T, and [a, b] indicates the device idle time interval.

[0073] In this embodiment, the device resource status is used to measure the degree of hardware resource usage during device operation, reflecting the device hardware resource usage. The device network status can reflect the quality of the device network connection, the stability of the network connection and the data transmission capacity. The parameters of the device network status may include network delay data, network packet loss rate, network bandwidth, etc. Weight coefficient 、 Used to adjust the impact of device resource status and device network status on device status score at different time periods. The value is between 0 and 1. For example =0.6 indicates that the device resource status has a greater impact on the score during idle periods. The value is determined based on the device usage scenario and key performance indicators. The device idle time interval refers to the period of time when the device is relatively idle. a and b are time points, such as [a=0:00, b=5:00]. The device status during this period is calculated to reflect the device load.

[0074] For example, after receiving the heartbeat packet sent by the target device, the remote server parses the device resource status (CPU, memory, disk usage) and the device network status (network delay, packet loss rate, bandwidth). Determine whether the time T of receiving the heartbeat packet is within the device idle time interval [a, b]. According to the time judgment result, select the corresponding weight coefficient and substitute it into the state score function to calculate the device status score. Taking the vending machine as an example, if a vending machine has a CPU usage of 40% and a network delay of 30ms at 10-11 am (non-idle period). Obtain these data through the heartbeat packet, and the remote server determines that the time is not in the idle interval and uses Calculate the device status score. If the score exceeds the preset threshold, it indicates that the device is operating well and can be upgraded directly. If the score is below the preset threshold, a more reliable upgrade strategy can be implemented to ensure normal operation of the vending machine.

[0075] This implementation comprehensively assesses the operating status of target devices by comprehensively considering device resource status and network status, combining weight coefficients and idle time intervals to accurately calculate device status scores. This allows for flexible adjustment of upgrade strategies based on device status scores, ensuring stability and security during device upgrades and improving the efficiency and intelligence of device management and maintenance.

[0076] In one embodiment of the present disclosure, the upgrade package is divided into blocks to obtain multiple upgrade block files, including:

[0077] Compare the upgrade package with the upgrade packages of previous versions.

[0078] Based on the comparison results, multiple difference blocks are determined, and each difference block is marked based on the difference type. The difference types include added difference, deleted difference, and modified difference.

[0079] The multiple difference blocks are divided into blocks to obtain multiple upgrade block files.

[0080] In this embodiment, multiple difference blocks are divided into blocks to obtain multiple upgrade block files, including:

[0081] The difference block with a data volume greater than or equal to the first threshold is divided into blocks to obtain a plurality of sub-difference blocks.

[0082] The plurality of sub-difference blocks and the difference block with a data amount smaller than a first threshold are used as a plurality of upgraded block files.

[0083] In this embodiment, the historical version upgrade package refers to the upgrade file of the previous version of the target device. Difference comparison refers to comparing the contents of the upgrade package with the historical version upgrade package to find the differences between the two. The difference block is the different content block obtained after comparing the upgrade package with the historical version upgrade package. The parameters include the size of the difference block, the position in the original upgrade package, etc. The difference type is used to mark the nature of the change in the difference block. The added difference represents the newly added file. The deleted difference represents the file deleted from the original file. The modified difference represents the modified part in the corresponding file content. The first threshold is a preset data volume standard, which is used to determine whether the difference block needs to be further divided into blocks. The sub-difference block includes a small block obtained by dividing the difference block with a larger data volume.

[0084] In this embodiment, by comparing the upgrade package with the previous version upgrade package, the differences are identified and marked, making it clear which parts need to be updated, deleted, or added. Large difference blocks are further divided into smaller blocks, reducing the size of individual data blocks. This facilitates more efficient network transmission and device storage processing, reducing transmission failures or slow processing caused by excessive data volumes. Finally, the divided sub-difference blocks and small difference blocks are used as upgrade block files for device upgrades.

[0085] For example, the latest upgrade package and the corresponding historical version upgrade package for the device are obtained. A first threshold is also set. This threshold can be determined based on the device's storage capacity, network transmission stability, and the overall size of the upgrade package; for example, 64KB or 128KB is commonly used. A file comparison algorithm is used to compare the upgrade package with the historical version upgrade package, either byte by byte or based on the file's internal data structure. This comparison identifies all differences between the two versions, which are then treated as difference blocks.

[0086] The difference type is determined based on the specific content changes of the difference block. If the content of a difference block does not exist in the previous version, it is marked as a new difference; if it exists in the previous version but is missing in the new version, it is marked as a deleted difference; if the content has changed, it is marked as a modified difference.

[0087] Check the data size of each difference block. For difference blocks with data sizes greater than or equal to the first threshold, adopt an appropriate block partitioning strategy. For example, you can partition them according to a fixed size to ensure that the data size of each sub-difference block is less than the first threshold. Organize the resulting sub-difference blocks and the difference blocks whose data sizes were originally less than the first threshold into multiple upgrade block files in a specific order. These files can be sorted based on factors such as difference type and location in the original file to facilitate sequential upgrade operations on subsequent devices.

[0088] This embodiment compares the upgrade package with historical versions, accurately identifying and categorizing differences, effectively reducing the amount of data required for the upgrade. By processing large data difference blocks in blocks, the size of individual data blocks is reduced, improving network transmission efficiency and device processing capabilities, and reducing transmission failures or slow processing caused by excessive data volumes. This method also ensures the order and accuracy of upgrade operations, improving the efficiency and success rate of device upgrades, and reducing the risks and costs of the upgrade process.
