Does the smart locker support remote system upgrades?

Smart lockers generally support remote system upgrades (OTA upgrades), which is one of their core functions. The specific implementation methods and characteristics are as follows:

OTA online upgrade mechanism
Through built-in networking modules such as WiFi/4G/5G, smart lockers can connect to cloud servers. After the manufacturer releases a new firmware or software version, the cabinet can automatically or manually trigger the download of the update package and complete the installation in the background without manual intervention.

Silent installation and seamless updates
Upgrades usually occur automatically when the device is idle. During the installation process, the screen displays a prompt of "upgrading" and locks the operation interface. After completion, the service is automatically restored, and the user is basically unaware.

Version verification and intelligent push
The cloud server will compare the current version number reported by the terminal device with the latest version. If there is a higher version, push upgrade instructions and file download links to the cabinet to ensure that the update accurately reaches the target device.

Upgrade failure response strategy
Support breakpoint continuation and multiple check mechanism. If the download is interrupted or the installation is abnormal, the system will automatically roll back to the old version to ensure the basic functions are available, and retry the upgrade process after the network is restored.

Security and compatibility guarantee
Upgrade files with encrypted signatures to prevent tampering; Strictly test the compatibility between the new version and hardware to avoid functional abnormalities caused by upgrades. Users can manually pause or schedule upgrade times through the management backend.
