[0061] With the rapid development of Internet of Things technology, Internet of Things devices can realize function iteration and bug fixing through software upgrade. In related technologies, the upgrade method of Internet of Things devices develops from offline wired upgrade to wireless remote upgrade such as WiFi, 4G / 5G, LoRa, etc. The scene can be extended to in-service upgrade, low-bandwidth, high-reliability demand scenarios, etc. Related technologies present three trends: wireless and remote upgrade methods, process lightweight and low power consumption, and intelligent and fault-tolerant strategies, to adapt to device resource constraints and complex application environments. However, the traditional upgrade method has the problem of low upgrade efficiency.

[0062] In view of the above technical problems, the embodiments of the present application provide an embedded system software upgrade method which can improve the upgrade efficiency of the application program. The following embodiments will specifically describe the embedded system software upgrade method.

[0063] The embedded system software upgrade method provided by the embodiments of the present application can be applied to, for example Figure 1The application environment shown. Among them, the terminal device 102 is connected with the cloud server 104 by wire or wireless, the terminal device 102 is provided with various types of embedded system application software, and the cloud server 104 stores the upgrade package of different embedded system application software. In a specific application, the terminal device 102 sends an upgrade request of application software to the cloud server, the cloud server 104 calls the upgrade package of application software from the cloud based on the upgrade request and transmits it to the terminal device 102, so that the terminal device 102 completes the upgrade of the application program. The terminal device 102 will transmit the early warning information to the cloud server 104 for recording during the upgrade process. Among them, the terminal device 102 can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices, the Internet of Things device can be a smart speaker, a smart TV, a smart air conditioner, a smart vehicle device, a projection device, etc. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, etc. The head-mounted device can be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc.

[0064] In one exemplary embodiment, as Figure 2 shown, an embedded system software upgrade method is provided, and the embodiment is exemplified by applying the method to a terminal device. In the embodiment, the method comprises:

[0065] S201, receiving the upgrade reply message sent by the cloud server;

[0066] Among them, the upgrade reply message is generated by the terminal device sending an upgrade request to the cloud server; the upgrade request carries the version number of the application software to be upgraded on the terminal device and the local firmware information; the upgrade reply message carries the upgrade package download link, which can be obtained through the upgrade package type list, which contains the upgrade package type and the corresponding type of upgrade package download link, for example, the upgrade package type includes full upgrade package and incremental upgrade package, and the upgrade package download link includes path 1 and path 2, wherein the full upgrade package corresponds to path 1, and the incremental upgrade package corresponds to path 2.

[0067] In the embodiment, the data collection module of the terminal device collects the local firmware information and the version number of the application software to be upgraded according to a preset period (for example, 24 hours), generates an upgrade request based on the collected information, and uploads the upgrade request to the cloud server. The cloud server compares the received version number of the application software with the pre-stored upgrade package version information in the cloud, and when the current version number of the application software is lower than the pre-stored upgrade package version information, extracts the upgrade package link corresponding to the version number of the application software to be upgraded, and transmits the upgrade reply message generated by the upgrade package link to the upgrade control module of the terminal device for subsequent upgrade processing of the application program.

[0068] S202, obtaining various types of upgrade packages required by the application software based on the download link, and screening a candidate upgrade package from the plurality of upgrade packages;

[0069] In the embodiment, when the upgrade package is obtained through the download link, the corresponding download link can be selected according to the arrangement order of the download link to obtain the various types of upgrade packages required by the application software. Alternatively, all the download links can be selected at the same time to obtain the various types of upgrade packages required by the application software.

[0070] In the embodiment, after the terminal device obtains the various types of upgrade packages required by the application software, the first optional way is to select a type of upgrade package in the upgrade package as a candidate upgrade package for upgrade processing. The second optional way is to first determine a full upgrade package and the current device state and network parameters of the terminal device from the upgrade package, and match the information of the full upgrade package with the current device state and network parameters of the terminal device. If the information of the full upgrade package matches the current device state and network parameters of the terminal device successfully, the full upgrade package is determined as the candidate upgrade package. If the information of the full upgrade package does not match the current device state and network parameters of the terminal device successfully, the incremental upgrade package is determined as the candidate upgrade package. The device state includes CPU load and remaining storage, and the network parameters include bandwidth and packet loss rate. For example, the information of the full upgrade package is the volume, and it is judged whether the remaining storage is greater than or equal to the volume of the full upgrade package and whether the bandwidth is greater than or equal to a preset bandwidth threshold. In the case where the remaining storage is greater than or equal to the volume of the full upgrade package and the bandwidth is greater than or equal to the preset bandwidth threshold, the full upgrade package is selected as the candidate upgrade package. In the case where the remaining storage is less than the volume of the full upgrade package or the bandwidth is less than the preset bandwidth threshold, the incremental upgrade package is selected as the candidate upgrade package.

[0071] S203, scoring the candidate upgrade package according to the download parameters of the candidate upgrade package to obtain a first scoring result;

[0072] The download parameters can be download rate, packet loss rate, and timeout number in the candidate upgrade package download process. The first score result can be a numerical value of 0-100.

[0073] In this embodiment, before scoring the candidate upgrade package, the candidate upgrade package obtained through screening is preprocessed according to the type of the candidate upgrade package, for example, the full upgrade package is compressed, and the differential file is generated for the incremental upgrade package; and the preprocessed upgrade package is added with UUID, SHA-256 check value, and parameter description. Then, the corresponding download method is selected for the candidate upgrade package according to the packet loss rate. That is, it is determined whether the current packet loss rate is less than or equal to a preset packet loss rate threshold. The first download mode is selected when the packet loss rate is less than or equal to the preset packet loss rate threshold, and the second download mode is selected when the packet loss rate is less than or equal to the preset packet loss rate threshold. For example, the TCP download method is used when the packet loss rate is less than or equal to 5%, and the download method of “UDP + sliding window retransmission” is used when the packet loss rate is greater than 5%.

[0074] In this embodiment, the candidate upgrade package is downloaded according to the download method determined in the foregoing, and the download rate, packet loss rate, and timeout number and other information are collected at a preset interval (for example, 100 ms) through the data collection module during the download process. The collected download rate, packet loss rate, and timeout number are processed according to a preset scoring model to obtain a score corresponding to the situation. Each collection parameter corresponds to a scoring mechanism, and the scores of various situations are weighted and summed to obtain a first score result. For example, the scoring mechanism of the download rate can be that 100 points are obtained when the download rate is greater than or equal to 500 KB / s, and 10 points are deducted for each 10% decrease. The scoring mechanism of the packet loss rate can be that 100 points are obtained when the packet loss rate is 0, and 10 points are deducted for each 1% increase. The scoring mechanism of the timeout number can be that 100 points are obtained when the timeout number is 0, and 20 points are deducted for each 1-time increase. Alternatively, the first scoring method is to score one parameter selected from the download rate, packet loss rate, and timeout number. The score obtained according to the scoring mechanism of the selected parameter of the corresponding type is taken as the first score result. For example, the download rate is selected for scoring. The download rate of the current candidate upgrade package is 450 KB / s. According to the scoring mechanism of the download rate, the current score can be calculated as 90 points, that is, the first score result is 90 points.

[0075] Optionally, the second way is to score from the download rate, the packet loss rate and the timeout number, and score the selected parameters according to the corresponding type of scoring mechanism, and finally the calculated scores are weighted and summed to obtain the first score result. The weights of the two parameters can be set according to the actual scene requirements. For example, the packet loss rate and the timeout number are selected for scoring, the current packet loss rate is 0.03, and the timeout number is 1. According to the corresponding scoring mechanism, the packet loss rate score is 70 points, and the timeout number score is 80 points. At the same time, the scoring weight of the packet loss rate is 0.5, and the scoring weight of the timeout number is 0.5. The packet loss rate score and the timeout number score are weighted and summed to obtain the first score result of 75 points.

[0076] Optionally, the third way is to select the download rate, the packet loss rate and the timeout number for scoring, and score the selected parameters according to the corresponding type of scoring mechanism, and finally the calculated scores are weighted and summed to obtain the first score result. The weights of the three parameters can be set according to the actual scene requirements. For example, the download rate is 400KB / s, the packet loss rate is 0.01, and the timeout number is 2. According to the corresponding type of scoring mechanism, the download rate score is 80 points, the packet loss rate score is 90 points, and the timeout number score is 60 points. Among them, the download rate weight is 0.4, the packet loss rate weight is 0.3, and the timeout number weight is 0.3. The download rate score, the packet loss rate score and the timeout number score are weighted and summed to obtain the first score result of 77 points.

[0077] S204, upgrading the application software according to the first score result to obtain an upgrade result.

[0078] The upgrade result includes success or failure state information, upgrade time consumption and version number of the application program after performing the upgrade operation.

[0079] In this embodiment, after the terminal device calculates the first score result, the score value corresponding to the first score result is compared with the preset score value, and whether the download parameter of the candidate upgrade package needs to be adjusted is determined according to the comparison result, that is, if the score value corresponding to the first score result is greater than the preset score value, it is indicated that the download process of the candidate upgrade package has no abnormal information, and the subsequent upgrade processing of the application software is performed through the candidate upgrade package to obtain an upgrade result. If the score value corresponding to the first score result is not greater than the preset score value, it is indicated that the download process of the candidate upgrade package has abnormal information, and the download information of the candidate upgrade package needs to be adjusted to complete the subsequent normal upgrade operation.

[0080] The embodiment first receives an upgrade reply message sent by a cloud server, then obtains various types of upgrade packages required by the application software based on a download link, and screens candidate upgrade packages from the multiple upgrade packages; scores the candidate upgrade packages according to the download parameters of the candidate upgrade packages to obtain a first score result; and upgrades the application software according to the first score result to obtain an upgrade result. By setting multiple types of upgrade packages to upgrade the application program, the application upgrade scene can be adapted to various application upgrade scenes, and by measuring the download environment of the selected candidate upgrade package through the first score result, it can be detected whether the download process of the upgrade package is abnormal, and the candidate upgrade package can be quickly adjusted, thereby improving the upgrade efficiency and reliability of the embedded system application software.

[0081] In one exemplary embodiment, as shown in Figure 3 The application software is upgraded according to the first score result to obtain an upgrade result, including:

[0082] S301, if the score value corresponding to the first score result is greater than a preset score value, the application software is upgraded using the candidate upgrade package to obtain an upgrade result;

[0083] The preset score value can be 60 points.

[0084] In the embodiment, when the score value corresponding to the first score result is greater than the preset score value, the score value corresponding to the first score result can be further classified and judged, that is, whether the score value is in a first interval greater than the preset score value. If the score value is in the first interval greater than the preset score value, it indicates that the candidate upgrade package is normally downloaded, and the application software is directly upgraded using the candidate upgrade package to obtain an upgrade result. If the score value is not in the first interval greater than the preset score value, it indicates that the candidate upgrade package is a risk download, and the terminal device needs to record a warning log for the risk information in the local storage and upload the risk information to the cloud server for storage. At the same time, the application software is upgraded using the candidate upgrade package to obtain an upgrade result. The first interval can be [80, 100]. For example, when the first score result is 85 points, which is in the first interval, it indicates that the candidate upgrade package is normally downloaded, and the application software is directly upgraded using the current candidate upgrade package to obtain an upgrade result. For example, when the first score result is 76 points, it is not in the first interval, the risk information at this time is recorded in the local storage and uploaded to the cloud server for storage, and at the same time, the application software is upgraded using the candidate upgrade package to obtain an upgrade result.

[0085] This step can accurately distinguish the download state of the upgrade package to improve the reliability of subsequent application program upgrade.

[0086] S302, if the score value corresponding to the first score result is not greater than the preset score value, switching the download method of the candidate upgrade package, updating the download parameter of the candidate upgrade package based on the switched download method, obtaining new download parameter of the candidate upgrade package, and re-scoring the candidate upgrade package according to the new download parameter, obtaining a second score result, upgrading the application software according to the second score result and the remaining upgrade packages in the plurality of upgrade packages, and obtaining an upgrade result.

[0087] The second score result can be a value of 0-100.

[0088] In this embodiment, when the score value corresponding to the first score result is not greater than the preset score value, it indicates that the current download state of the candidate upgrade package is abnormal, and the download operation of the candidate upgrade package is immediately suspended. The terminal device records the abnormal information, and simultaneously switches the download method of the candidate upgrade package (for example, switches from "TCP" to "UDP + sliding window retransmission"). The candidate upgrade package is downloaded by using the switched download method. Since the download parameters corresponding to different download methods are different, the download rate, the packet loss rate and the timeout number are re-acquired by the data acquisition module according to the preset interval, the candidate upgrade package is re-scored according to the newly acquired download parameters, the download parameter of the candidate upgrade package is updated, and the candidate upgrade package is re-scored according to the updated download parameter, so as to obtain a second score result. When the application software is upgraded according to the second score result and the remaining upgrade packages in the plurality of upgrade packages, an upgrade result is obtained. Optionally, the first way is to determine whether the second score result is greater than the preset score value. If the second score result is greater than the preset score value, the application software is upgraded by using the candidate upgrade package, and an upgrade result is obtained. If the second score result is not greater than the preset score value, the download method of the candidate upgrade package is switched, and the download parameter of the candidate upgrade package is updated based on the switched download method, new download parameter of the candidate upgrade package is obtained, and the candidate upgrade package is re-scored according to the new download parameter, a new score result is obtained, and the application software is upgraded according to the new score result and the remaining upgrade packages in the plurality of upgrade packages, and an upgrade result is obtained.

[0089] Optionally, the second way is as shown in Figure 4 , which includes:

[0090] S401, if the score value corresponding to the first score result is not greater than the preset score value, switching the download method of the candidate upgrade package, updating the download parameter of the candidate upgrade package based on the switched download method, obtaining new download parameter of the candidate upgrade package, and re-scoring the candidate upgrade package according to the new download parameter, obtaining a second score result, upgrading the application software according to the second score result and the remaining upgrade packages in the plurality of upgrade packages, and obtaining an upgrade result.

[0091] In this embodiment, the execution principle of this step is the same as that of S301, and will not be described here.

[0092] S402, if the score value corresponding to the second score result is not greater than the preset score value, determining a new candidate upgrade package from the remaining upgrade packages, and returning to perform the step of scoring the candidate upgrade package according to the download parameter of the candidate upgrade package to obtain a first score result based on the new candidate upgrade package.

[0093] In the embodiment, the adjustment manner of the download parameter of the candidate upgrade package includes switching the type of the candidate upgrade package in addition to adjusting only the download method of the candidate upgrade package. This situation is applied when the download methods corresponding to the candidate upgrade package have all been used, and the score results corresponding to all the download methods are not greater than the preset score value, indicating that there is abnormal information in the download process of the candidate upgrade package, and the type of the candidate upgrade package should be switched, and the switched candidate upgrade package is rescored to ensure the reliability of the application upgrade. Since it has been determined that the score value corresponding to the first score result is not greater than the preset score value, the download process of the candidate upgrade package downloaded according to the current download method has abnormal information. When the score value corresponding to the second score result is not greater than the preset score value, it indicates that the download process of the candidate upgrade package with the switched download method still has abnormal information. At this time, the download methods of the candidate upgrade package have all been used, and the conditions for normal download cannot still be met. At this time, a new candidate upgrade package is determined from the remaining upgrade packages, and the download method of the new candidate upgrade package is determined. The new candidate upgrade is downloaded according to the download method. The download rate, the packet loss rate, and the timeout number in the download process are collected at a preset interval through the data collection module. The download process of the new candidate upgrade package is scored according to the collected parameters. Whether the download process of the new candidate upgrade package has abnormal information, whether the download method of the new candidate upgrade package needs to be switched, or the application is directly upgraded according to the new candidate upgrade package is determined according to the score value, so as to realize the efficiency and reliability of the embedded system application software upgrade.

[0094] For example, the upgrade package of the application program A includes two types of full upgrade package and incremental upgrade package, the full upgrade package is selected as the candidate upgrade package based on the remaining storage and bandwidth of the terminal device, TCP is selected as the download method of the candidate upgrade package based on the packet loss rate of the terminal device, the candidate upgrade package is downloaded according to TCP, and the download process of the candidate upgrade package is scored in real time according to the download rate, the packet loss rate and the timeout number corresponding to the download method, and the first score result is 56, which is less than the preset score value. The download method of the candidate upgrade package is switched to UDP + sliding window retransmission, and the candidate upgrade package is downloaded again according to the switched download method. The download rate, packet loss rate and timeout number corresponding to the switched download method are collected in real time, the candidate upgrade package is scored according to the newly collected data, and the second score result is 58. At this time, the download method of the full upgrade package has been used, and there are abnormal information, which does not meet the upgrade requirement. The full upgrade package is switched to the incremental upgrade package, at this time the incremental upgrade package is the candidate upgrade package, the packet loss rate of the current terminal device is obtained to reselect the download method for downloading the candidate upgrade package, and the candidate upgrade package is scored in real time according to the download parameters. When the score is greater than the preset score value, the application program is upgraded according to the current candidate upgrade package, and the upgrade result is obtained. When the score is not greater than the preset score value, the download method is switched, and the candidate upgrade package is downloaded again based on the switched download method. The execution principle of this case is the same as that of step S302, and details are not repeated here.

[0095] By scoring the download process of the candidate upgrade package and switching the type of the candidate upgrade package in time when the score does not meet the normal download condition, the upgrade efficiency and reliability of the embedded system application software are improved.

[0096] In an exemplary embodiment, as shown in FIG. 5, Figure 5 the application software is upgraded by using the candidate upgrade package to obtain an upgrade result, including:

[0097] S501, the candidate upgrade package is verified;

[0098] The candidate upgrade package can be verified by SHA-256 value, or can be verified by other verification methods, which is not limited here.

[0099] In the embodiment, when the real-time download parameter of the candidate upgrade package always meets the condition that the score value is greater than the preset score value, it is represented that the candidate upgrade package is normally downloaded. After the candidate upgrade package is downloaded, the check value of the candidate upgrade package is compared with the SHA-256 value sent by the cloud server through the check recovery module of the terminal device. When the check value of the candidate upgrade package is consistent with the SHA-256 value sent by the cloud server, it is represented that the check passes. When the check value of the candidate upgrade package is inconsistent with the SHA-256 value sent by the cloud server, it is represented that the check does not pass, and the candidate upgrade package is processed according to the check result.

[0100] S502, in the case of passing the check, the application software is upgraded by using the candidate upgrade package, and an upgrade result is obtained;

[0101] In the embodiment, when the check value of the candidate upgrade package is consistent with the SHA-256 value sent by the cloud server, it is represented that the check passes. In this case, the average CPU load of the preset time range is calculated by the upgrade control module of the terminal device, and the average CPU load is compared with the preset load threshold. If the average CPU load is less than or equal to the preset load threshold, the application program is immediately upgraded by the candidate upgrade package. If the average CPU load is greater than the preset load threshold, the waiting area is entered, and the load at each time is continuously monitored. When the average CPU load in the preset time range is less than or equal to the preset load threshold, the application program is upgraded by the candidate upgrade package. The preset time range can be a 10-second period before the current time, or other time ranges, which are not limited herein. The preset load threshold can be 50%, or can be set according to actual scene requirements, which are not limited herein.

[0102] S503, in the case of failing to pass the check, the download method of the candidate upgrade package is switched, the download parameter of the candidate upgrade package is updated based on the switched download method, the new download parameter of the candidate upgrade package is obtained, the upgrade package is re-scored according to the new download parameter, the third score result is obtained, the application software is upgraded according to the third score result and the remaining upgrade packages in the plurality of upgrade packages, and the upgrade result is obtained.

[0103] In the embodiment, when the check value of the candidate upgrade package is inconsistent with the SHA-256 value sent by the cloud server, the check fails, which indicates that the download process of the candidate upgrade package is abnormal, the download method of the candidate upgrade package is switched, the candidate upgrade package is downloaded according to the switched download method, and the rate, the packet loss rate, and the timeout number in the download process are collected in real time, the third score result is obtained by scoring the collected parameters. When the third score result is greater than the preset score value, the application software is upgraded by using the candidate upgrade package, and the upgrade result is obtained. When the third score result is not greater than the preset score value, a new candidate upgrade package is determined from the remaining upgrade packages, and the step of scoring the candidate upgrade package according to the download parameters of the candidate upgrade package to obtain the first score result is returned based on the new candidate upgrade package.

[0104] The candidate upgrade package is checked through the downloaded candidate upgrade package, the application program is upgraded through the candidate upgrade package meeting the check condition, and the candidate upgrade package not meeting the check condition is adjusted in time, so that the efficiency and reliability of the embedded system application software upgrade are improved.

[0105] In an exemplary embodiment, as shown in Figure 6 The application software is upgraded according to the third score result and the remaining upgrade packages in the plurality of upgrade packages, and the upgrade result is obtained, including:

[0106] S601, if the score value corresponding to the third score result is greater than the preset score value, the application software is upgraded by using the candidate upgrade package, and the upgrade result is obtained;

[0107] In the embodiment, for the case that the score value corresponding to the third score result is greater than the preset score value, it is indicated that the candidate upgrade package is normally downloaded and there is no abnormal information. When the application software is upgraded by using the candidate upgrade package, the upgrade result is obtained, and the execution principle of S301 is the same, which will not be described herein.

[0108] S602, if the score value corresponding to the third score result is not greater than the preset score value, a new candidate upgrade package is determined from the remaining upgrade packages, and the step of scoring the candidate upgrade package according to the download parameters of the candidate upgrade package to obtain the first score result is returned based on the new candidate upgrade package.

[0109] In the embodiment, when the score value corresponding to the third score result is not greater than the preset score value, it indicates that the download methods of the candidate upgrade package have all been used, and the download processes of all the download methods have abnormal information, and the same candidate upgrade package has no other download method to use. In order to ensure the smooth upgrade of the application program, a new candidate upgrade package is determined from the remaining upgrade packages, a corresponding download method is selected for the new candidate upgrade package according to the packet loss rate of the terminal device, the new candidate upgrade package is downloaded according to the selected download method, and the step of returning to execute the terminal device-based data collection system to collect the download parameters and score the new candidate upgrade package according to the download parameters to obtain a first score result is performed.

[0110] By scoring the download process of the candidate upgrade package and switching the type of the candidate upgrade package in time when the score does not satisfy the normal download condition, the upgrade efficiency and reliability of the embedded system application software are improved.

[0111] In an exemplary embodiment, as shown in Figure 7 FIG. 1, the candidate upgrade package is selected from the plurality of upgrade packages, including:

[0112] S701, determining a full-mode type upgrade package in the plurality of upgrade packages, and determining a remaining storage capacity of the terminal device and a current network transmission bandwidth;

[0113] In the embodiment, the full-mode type upgrade package can be determined from the plurality of upgrade packages according to the name or number of the upgrade package. The remaining storage capacity of the terminal device and the current network transmission bandwidth can be collected by the upgrade control module or collected by a sensor.

[0114] S702, if the remaining storage capacity is greater than or equal to the volume of the full-mode type upgrade package, and the current network transmission bandwidth is greater than or equal to a preset bandwidth threshold, determining the full-mode type upgrade package in the plurality of upgrade packages as the candidate upgrade package;

[0115] The preset bandwidth threshold can be 1 Mbps.

[0116] In the embodiment, when determining the candidate upgrade package, optionally, in a first mode, the remaining storage is compared with the volume of the full-mode type upgrade package respectively, and the current network transmission bandwidth is compared with the preset bandwidth threshold, when the remaining storage is greater than or equal to the volume of the full-mode type upgrade package, and the current network transmission bandwidth is greater than or equal to the preset bandwidth threshold, the full-mode type upgrade package is determined as the candidate upgrade package. Optionally, in a second mode, the remaining storage is compared with the preset multiple of the volume of the full-mode type upgrade package respectively, and the current network transmission bandwidth is compared with the preset bandwidth threshold, when the remaining storage is greater than or equal to the preset multiple of the volume of the full-mode type upgrade package, and the current network transmission bandwidth is greater than or equal to the preset bandwidth threshold, the full-mode type upgrade package is determined as the candidate upgrade package. For example, the remaining storage is greater than or equal to the volume of the full-mode type upgrade package multiplied by 1.2, and the bandwidth is greater than or equal to 1 Mbps, the full-mode type upgrade package is determined as the candidate upgrade package.

[0117] In S703, if the remaining storage is less than the volume of the full-mode type upgrade package, or the current network transmission bandwidth is less than the preset bandwidth threshold, the incremental-mode type upgrade package in the plurality of upgrade packages is determined as the candidate upgrade package.

[0118] In the embodiment, optionally, when the remaining storage is less than the volume of the full-mode type upgrade package, or the current network transmission bandwidth is less than the preset bandwidth threshold, the incremental-mode type upgrade package in the plurality of upgrade packages is determined as the candidate upgrade package; optionally, when the remaining storage is less than the preset multiple of the volume of the full-mode type upgrade package, or the current network transmission bandwidth is less than the preset bandwidth threshold, the incremental-mode type upgrade package in the plurality of upgrade packages is determined as the candidate upgrade package. For example, the current network transmission bandwidth is 1.2 Mbps, which is greater than the preset bandwidth threshold, and the remaining storage is less than the volume of the full-mode type upgrade package, the incremental-mode type upgrade package is determined as the candidate upgrade package.

[0119] By providing a plurality of types of upgrade packages, the scene adaptability is enhanced, the high-load device can delay upgrade, the low-bandwidth device selects incremental upgrade, and different scenes are adapted.

[0120] Optionally, for the case that the terminal device needs to upgrade multiple application softwares simultaneously, the terminal device sends an upgrade request to the cloud server, the upgrade request containing version numbers of the multiple application softwares to be upgraded and corresponding local firmware information, the cloud server obtaining upgrade package download links of the multiple application softwares to be upgraded based on the upgrade request and transmitting the upgrade package download links to the terminal device, the terminal device obtaining the upgrade packages of the multiple application softwares to be upgraded based on the upgrade package download links, determining candidate upgrade packages of the multiple application softwares to be upgraded from the upgrade packages, and scoring download parameters of the candidate upgrade packages respectively, and if there is at least one candidate upgrade package whose first score result is not greater than a preset score value, returning to the step of determining the candidate upgrade packages of the multiple application softwares to be upgraded from the upgrade packages, that is, the upgrade processes of all the application softwares are executed synchronously. In particular, when scoring the real-time download parameters of the candidate upgrade packages respectively, optionally, the first way is to score the real-time download parameters of each candidate upgrade package according to the arrangement order of the application software version numbers, when the first first score result is not greater than the preset score value, suspending the download process of the corresponding candidate upgrade package, and not executing the download process of the remaining candidate upgrade packages, and returning to the step of determining the candidate upgrade packages of the multiple application softwares to be upgraded from the upgrade packages; and optionally, the second way is to score the real-time download parameters of the candidate upgrade packages in parallel, when the first first score result is not greater than the preset score value, suspending the download processes of all the candidate upgrade packages, and returning to the step of determining the candidate upgrade packages of the multiple application softwares to be upgraded from the upgrade packages.

[0121] By simultaneously upgrading multiple application softwares and adjusting the candidate upgrade packages that do not meet the normal download in time, the efficiency and reliability of the upgrade of the application software of the embedded system are improved.
