Design Of Wireless Intelligent Home Monitoring System Based On Multi-sensor Fusion Technology

Nowadays, with human civilization into the information age, construction has not only used to avoid hot, sunshine, wind and cold, but also been endowed with soul and intelligent by modern information technology. Through the rational allocation of natural resources, construction achieves the harmony between human and nature. With the development of multi-sensor fusion technology, people become to pay more attention and have high requirements on safe, comfortable, convenient living environment. Therefore, intelligent home security has become an inevitable trend of residential development.This thesis researched an intelligent home security monitoring system with a low cost, simple and flexible operation and using the family PC as the control unit. Moreover, the use of ZigBee short-range wireless communication also applied into this home surveillance network. This paper mainly completed the whole design of intelligent home monitoring, setting up the multi-sensor fusion mathematical model, the research on abnormal condition monitoring algorithm, system build, testing and so on tasks. The innovation and main results of this thesis are as follows:In this study, it designed a home control network program based on ZigBee wireless communications technology and wireless transceiver module based on the CC2430chip. Furthermore, it researched the setting approach for transceiver and completed the communications test of ZigBee wireless communication technology.This thesis, in basis of unusual target of serial port camera by the indoor track detection, presented the adaptive state differential detection by combination background subtraction and frame difference method, detection of small target tracking, adaptive background replacement method. In addition, this paper studied the JPEG image decoding, the conversion of image gray value, the binarization processing method, and using erosion and dilation techniques to do morphological image denoising.In this paper, it was the first time proposed the home fires monitoring program based on the multi-temperature sensor data tier fusion and multi-smoke sensor decision layer fusion, designed the monitoring system of multi-temperature sensor and multi-smoke sensors, achieved to build up multi-temperature sensor data tier fusion and multi-smoke sensor decision layer fusion model, realized the real-time monitoring of home fires, improved the accuracy of home fires monitor and decrease to happen the false positives, false, etc..The simulation and test results show that the proposed scheme is advanced and efficient. The intelligent home security monitoring and control system can meet the technical requirements.
