After the DATA pin of the temperature and humidity sensing module outputs 40-bit DATA, the DATA is continuously output to be in a low level for 50 microseconds and then is converted into an input state, and due to the fact that the pull-up resistor is changed to be in a high level. This time data reading finishes, and the inside environmental temperature humidity data of reexamining of humiture sensing module, the initial rerecording data of grappling waits for next arrival of external signal.
And S3, after acquiring the temperature and humidity data acquired by the temperature and humidity sensing module, the main controller in the NB-IoT terminal converts and packages the temperature and humidity data, and then packs the data by means of the NB-IoT communication module in the NB-IoT terminal and sends the data to the Internet of things open platform.

And S4, after the Internet of things open platform receives the reported data, analyzing the reported data through the self-defined coding and decoding plug-in data, and pushing the analyzed data to an application server of the man-machine interaction platform.
And S5, the application server writes a background program and is responsible for receiving the data pushed by the NB-IoT terminal and storing the data into an internal MySQL database, and at the moment, the user can check the reported data information through an intelligent mobile terminal in the man-machine interaction platform.
S6, issuing an operation instruction by a user through a man-machine interaction platform, for example, striking a fan button on an operation interface of the intelligent mobile terminal, and then issuing command data by the application server calling an issuing command interface of the Internet of things open platform.
And S7, after receiving the issued command, the Internet of things open platform encodes the command through a customized coding and decoding plug-in, then sends the data to the NB-IoT communication module and finally to the main controller, and the main controller immediately performs corresponding operation on a fan in the system.
The internet of things open platform sends coded data to an NB-IoT communication module through a CoAP protocol, the NB-IoT communication module receives the data and then sends the data to an RXD pin PB11 of a serial port 3 of a main controller through a serial port sending pin TXD, the serial port 3 is set to be received in an interrupt mode, the data received by the serial port 3 are stored in a Buffer area Buffer array in an interrupt service function, a Buffer area is read in a main function in a circulating mode, after command data for opening a fan is read, the main controller controls a PA13 to output a high level, a relay switch connected with the main controller is controlled to be closed, and the fan is opened.
