It is assumed that there is a temperature sensor and temperature controller of one type (denominated SXC) and a smoke sensor and sound alarm sensor of another type (denominated TNW). In adapting these several sensors, it may be agreed that: the sensor numbers of the SXC temperature sensor, the temperature controller, the TNW smoke sensor and the sound alarm sensor are respectively 1, 2, 3 and 4, and the addresses are respectively '11111111', '22222222', '33333333' and '44444444'. The SXC sensor uses ttyUSB0 equipment files to exchange information with the gateway of the Internet of things, and the TNW sensor uses ttyUSB1 equipment files to exchange information with the gateway of the Internet of things.
The sensor data structure includes, but is not limited to, at least one of the following elements:

step two: the sensor adaptation module obtains a sensor number of 4 from the message, thereby confirming that the message corresponds to a TNW sensor, and the sensor sending the message is a TNW type voice alarm sensor;
step three: the sensor adaptation module acquires a TNW sensor data structure in the registered sensor structures;
step four: the sensor adaptation module analyzes data of the TNW sensor from the Internet of things platform according to a 'sensor control instruction encapsulation function pointer' in a TNW sensor data structure, and encapsulates the analyzed data into sensor data;
step five: the sensor adaptation module sends the encapsulated TNW sensor data to the sensor interaction module, and the sensor interaction module sends the TNW sensor data to the sensor through a device driver ttyUSB 1.
