Abstract: In order to promote intelligent building,a new intelligent window is designed,and its software and hardware implementation plan is studied.The mechanical transmission of the intelligent window adopts the gear and rack drive,the temperature and humidity of sensor DHT11,the harmful and combustible gas sensor MQ-2 and the infrared thermoluminescence sensor of the human body are used as the environmental monitoring sensors,and the sensor networks are established through the ZigBee wireless communication technology.Taking MSP430F149 single chip microcontroller(SCM)as the control core,by analyzing the sensor information sent by the ZigBee coordinator,the stepper motor is controlled to realize the automatic switch window.The experimental results show that the system has the functions of intelligent anti-theft,rain proof,anti harmful gas,intelligent sending SMS,voice prompt and so on.It has good practicability and human-computer interaction.
