[0093] The product verification scheme mainly verifies intelligent remote control, intelligent data collection, and cloud-based AI triggered collection functions.

[0094] 1. Intelligent remote control function verification scheme

[0095] The main purpose of remote control is to forward control data flow from the cloud. The data flow direction is shown by the dashed line in Figure 6 .

[0096] Using a smartphone or other remote devices connected to the private cloud or the Internet, through the use of custom software, the start and stop control of the fan controlled by edge node 2 can be achieved.
