the near-end machine control unit communicates with the cloud service in real time and periodically checks the software version of the near-end machine system;
if the control unit detects that a new version needs to be updated, the control unit establishes a file transmission channel with the server and downloads the latest file to the local;
after downloading, the system automatically executes a new system program;
the remote machine operates in a similar manner to the near-end machine.
Remarking:
releasing system software in a skylight point again and again;
if the upgrading fails, the system still uses the original program to execute, and the normal use of the system cannot be influenced;
whether the device needs to be upgraded may be determined based on a configuration policy.
