Assume that the fan and accessories terminal 11 and the local control module 12 are located in a building in Beijing, the service center module 13 is located in a computer room in Chongqing, and the user terminal 14 is located in a hotel in Hong Kong.

The daily work situation is:

The local control module 12 automatically sends a query command to the fan and accessory terminal 11 every 5 seconds or so. After receiving the query command, the fan and accessory terminal 11 collects the information collected by the sensor that comes with the fan to indicate the working status of the fan and the accessory. The monitoring signal of the working environment status is fed back to the local control module 12 .

The so-called automatic control strategy refers to the optimal control strategy according to a certain standard. For example, when the maximum ventilation volume is required, the automatic control strategy is that all fans work at the maximum power; when energy consumption needs to be saved, the automatic control strategy is to maintain In the case of the lowest air flow, the fans work at low power. The service center module 13 sends the new automatic control strategy to the local control module 12, and the local control module 12 automatically controls specific fans and accessories according to the automatic control strategy.

The situation of user remote control is:

The user opens a known browser on a computer provided by a certain hotel in Hong Kong or on a computer that comes with it as a user terminal 14, such as Internet Explorer, and inputs the domain name or IP address of the service center module 13, and the service center module 13 located in a computer room in Chongqing gives feedback Go back to the login page. The user enters the account number and password on the login page, sends a remote login request to the service center module 13, and enters the query and control page after getting permission from the service center module 13, and can perform remote control while checking the working status of the fan and accessory terminals in real time.

If the user has set the rotating speed of the No. 2 blower fan of a certain building in Beijing through the user terminal 14, the user terminal 14 sends the remote control command to the service center module 13 located in a certain computer room in Chongqing in the form of a data packet, and the service center module 13 then sets the The remote control command is sent to the local control module 12 located in a building in Beijing, and finally the local control module 12 controls the No. 2 fan of the building to change the speed. The result of this rotation speed change is finally displayed to the user's user terminal 14 in real time according to the daily real-time monitoring process.
