Research Of Intelligent Casement Window Based On GSM Module

With the wide use of new home appliance from1980s, residence has been labeled by the word "intelligentization",from which the research of the intelligent window had made great progress.Nowadays,there are several kinds of anti-fire or anti-water intelligent window product,with disadvantages of little function,high cost,non-alert and so on.Thus,an intelligent window based on GSM module is proposed,which not only can well get the signal of smog sensor and infrared sensor but also can well dispose the data of temperature sensor and humidity sensor.The following parts are the primary results of the research:(1)A kind of window actuator for the casement window has been designed with the output of double-chain structure and the transmission of wormwheel-worm-gear(2)The drive circuits of smog sensor and infrared sensor have been designed,the codes of temperature sensor and humidity sensor have been compiled.After analyzing the interrupt function of the51-SCM,it has been developed outside.The primary circuit for the SCM is worked out,and the main program is finished, actualizing the automation of open and close of windows according different circumstance.(3)The communication circuit, SIM circuit and switch circuit of the GSM module have been designed,between which the soft interface is established.The code of SMS桝lert has been compiled. After that,the process of sending SMS of the GSM module triggered by51-SCM has been actualized.(4)The system is tested respectively under single circumstance and mixed circumstance, actualizing the SMS-Alert by the priority and the automatic open-close of the window.
