The embodiments of this application can be applied to Internet of Things devices, by analyzing the occupancy of system resources in the Internet of Things devices to provide conditions that can be upgraded normally, so that the upgrade can be completed in time, and the operation of the main application program can be resumed in time, thereby Avoid running system instability problems caused by downloading and upgrading.

In the prior art, the hardware resources and memory resources of the Internet of Things device may be fixed and not large enough. During the running of at least one application program of the Internet of Things device, the program in the Internet of Things device may be upgraded, for example, a general upgrade of an application program, a version upgrade, or a firmware upgrade, and so on. During the upgrade process, in order to ensure the security and reliability of the network connection between the IoT device and the upgraded father, it is usually necessary for the IoT device and the upgrade server to pass a secure HTTPS (Hypertext Transfer Protocol Secure, Hypertext Transfer Security Protocol). ) Download the program to be upgraded, which is the installation package. However, since the download and upgrade process of HTTPS needs to increase the process of certificate exchange and handshake verification, the consumption of system memory resources is greater. Therefore, resource-constrained IoT devices are often unable to download and upgrade using HTTPS. Moreover, in some resource-constrained IoT devices, if the application program is run and the upgrade task is downloaded at the same time, due to the limited resources, the technical problem of the instability of the operating system of the IoT device is prone to occur. In order to solve the above technical problems, the inventor proposed the technical solution of this application.

In the embodiment of the present application, for resource-constrained IoT devices, the upgrade trigger message sent by the device management server can be detected during the operation of at least one application program, and the response to the upgrade trigger message can be based on the at least one application program. Occupies resources, close at least part of the application, so that the resources in the IoT device system can perform the upgrade task. After downloading the program to be upgraded from the upgrade server, the program to be upgraded can be run to complete the upgrade task of the IoT device, and then at least one application can be rerun. At this time, the IoT device completes the upgrade task, and reruns at least one application after the upgrade is completed to restore the system of the IoT device to a stable state, which can solve the system failure caused by the upgrade task and the main application running at the same time. Stable technical issues.

The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, a flowchart of an embodiment of a program upgrade method for an Internet of Things device provided by an embodiment of this application, the method may include the following steps:

101: During the running process of at least one application program, detect an upgrade trigger message sent by the device management server.

The embodiments of the present application may be applied to Internet of Things devices. The Internet of Things devices may refer to electronic devices with limited resources, and specifically may refer to electronic devices with memory resources less than a set memory threshold.

When IoT devices are running normally, they need the support of multiple programs. For example, they can include: Bootloader, OS (operating system, operating system), timing program, and network connection program, etc. For some specific functions of the Internet of Things Devices, for example, image sensors, sound sensors, etc., may also include applications that provide certain functions for users, for example, applications that display images, applications that output sounds for users, and so on.

The device management server can be used to provide computing services. For example, it can be composed of personal computers, supercomputers, laptops, and other devices, or it can be composed of cloud servers. The embodiment of the application does not make specific types of device management servers. Too much restriction.

The device management server refers to the server used to manage the Internet of Things devices. It can usually respond to and process service requests from the Internet of Things devices, and can also manage and control applications in the Internet of Things devices. In some embodiments, when the user application in the Internet of Things device is version updated or upgraded, the device management server may be composed of a third-party server, and the third-party server may specifically refer to the developer who developed the user application. The access server set by the user application.

When the device management server determines that there is an upgrade requirement for the IoT device, it can send an upgrade trigger message to the IoT device. The upgrade trigger message may include information such as the program name and download address of the program to be upgraded, and the download address can be determined through the upgrade trigger message, so that the program to be upgraded can be downloaded from the upgrade server.

The programs used on IoT devices do not include the operating systems and network modules of IoT devices.

102: In response to the upgrade trigger message, close at least part of the application based on the resource occupation of the at least one application.

At least one application in the Internet of Things device consumes resources of the Internet of Things device during the running process, which may include hardware resources or memory resources. Due to the small resources of the IoT device, if at least one application has a large resource occupancy, the remaining resources of the IoT device are small, and the upgrade cannot be performed in time, or there is a resource contention between the upgrade program and the operation of at least one application. . For example, suppose the memory resource of the IoT device is 100K, and the resource occupied by at least one application is 60K, and the remaining resource is 40K, but if the upgrade task requires 60K of memory resources, the upgrade cannot be completed due to insufficient remaining resources. If the upgrade task is 38K of memory resources are required. 98K of memory resources are required to upgrade at least one application and the upgrade task at the same time. Task upgrades can be performed. However, due to excessive memory resource consumption, resource conflicts and resource contention are prone to occur. Lead to instability of IoT devices.

After responding to the upgrade trigger message, the upgrade can be started. At this time, based on the resource occupation of at least one application, at least part of the application can be closed. By closing at least part of the application, part of the resources in the IoT device can be unoccupied, and the supply of applicable resources can be increased. The device can be upgraded after closing at least some applications.

In some embodiments, the downloading of the program to be upgraded from the upgrade server may specifically be: based on the download address, sending a download request to the upgrade server corresponding to the download address, and establishing a connection with the upgrade server based on the download request. After the handshake connection is completed, after the certificate is exchanged with the upgrade server according to the established handshake connection, the program to be upgraded can be downloaded from the upgrade server.

104: Run the program to be upgraded to complete the upgrade task of the Internet of Things device.

After downloading the program to be upgraded, the Internet of Things device can start the program to be upgraded to complete the upgrade task of the Internet of Things device.

105: Re-run the at least one application program.

The re-running the at least one application program may include restarting at least part of the closed application program to re-run the at least one application program.

In the embodiment of the present application, by targeting resource-constrained IoT devices, the upgrade trigger message sent by the device management server can be detected during the operation of at least one application, and the upgrade trigger message can be based on at least one application. The resources of the program are occupied, and at least part of the application programs are closed, so that the resources in the IoT device system can perform the upgrade task. After downloading the program to be upgraded from the upgrade server, the program to be upgraded can be run to complete the upgrade task of the IoT device, and then at least one application can be rerun. At this time, the IoT device completes the upgrade task, and reruns at least one application after the upgrade is completed to restore the system of the IoT device to a stable state, which can solve the system failure caused by the upgrade task and the main application running at the same time. Stable technical issues.

In order to solve the resource conflict problem caused by the download task and at least one application program running at the same time, all applications can be closed to increase the available resources in the system, so as to ensure that the program upgrade can be completed normally. As an embodiment, in response to the upgrade trigger message, shutting down at least part of the application based on the resource occupation of the at least one application may include:

In response to the upgrade trigger message, all applications are closed based on the resource occupation of the at least one application.

In order to ensure the security of the download, the downloading of the program to be upgraded from the upgrade server may include:

Based on the hypertext transmission security protocol, download the program to be upgraded from the upgrade server.

Because the hypertext transmission security protocol requires more resources, it cannot be used when at least part of the application is not closed or is affected by resource restrictions and has a poor use effect. In this application, closing at least part of the application can enable hypertext transmission The security protocol can be used to improve the security of the download, thereby improving the security of the upgrade task.
