 Step 1: The sensor interaction module reads the data of the device file ttyUSBO and transmits it to the sensor adaptation module.

 Step 2: The sensor adaptation module determines that the received sensor data is sent by the SXC sensor;

Step 3: The sensor adaptation module acquires SXC sensing in the registered sensor data structure Data structure

 Step 4: The sensor adaptation module uses the "sensor data analysis function pointer" in the SXC sensor data structure to resolve the sensor data.

 It can be seen that the uplink processing flow can be represented as shown in Figure 3. The sensor interaction module needs to receive the sensor message and send it to the sensor adaptation module; the sensor adaptation module determines the sensor type according to the received sensor message, and searches for the sensor data structure according to the sensor type, according to which the received Sensor data in sensor messages.

 Step 3: The sensor adaptation module acquires the TNW sensor data structure in the registered sensor structure;

 Step 4: The sensor adaptation module parses the data of the TNW sensor from the Internet of Things platform according to the “sensor control instruction package function pointer” in the data structure of the TNW sensor, and encapsulates the parsed data into sensor data;

 Step 5: The sensor adaptation module sends the encapsulated TNW sensor data to the sensor interaction module, and the sensor interaction module sends the signal to the sensor through the device driver file ttyUSB 1.

 It can be seen that the downlink processing flow can be represented as shown in FIG. 4. The sensor adaptation module needs to determine the sensor type according to the received protocol data, search for the sensor data structure according to the determined sensor type, and apply the sensor data structure to encapsulate the sensor data, and then send the sealed sensor data.
