[0099] It can be seen that the implementation of this optional implementation method can perform business processing on the device control data to be sent to the physical terminal through microservice containers at the edge of the network, which can improve the efficiency, accuracy and reliability of business processing.

[0100] It can be seen that the implementation of the embodiment of the present invention can send the device control data set by the user on the Internet of Things platform to the central server, and then send it from the central server to the network edge, which performs business processing on the device control data, that is, the cloud resource requirements of the physical terminal are met through the network edge, which not only reduces the insufficient bandwidth and energy resources required by the physical terminal due to the use of a centralized data center for terminal control, but also improves the efficiency of physical terminal control and the security of physical terminal data privacy. In addition, by giving the physical terminal the ability of edge computing, the functions of the physical terminal can be enriched.
