| In recent years, with the development and popularity of smart phones and smart hardware devices,many technology companies begin to let them as the entrance of the smart home platform, and improve the intelligent hardware system, and in cooperation with the embedded technology and high level integration chip technology to achieve more intelligent technology products.Therefore, Internet of things has become a hot area of current global concern, and it was given as "the most significant technology innovation after Internet technology". It is a new concept of intelligent through the infrared sensor, radio frequency identification technology,relaying on many network communication protocol, to finish information services with the connection of the smart devices and Internet,to achieve remote monitoring network, device management and other functions.This topic is in the context of the overall development of the Internet Things,with embedded technology, wireless networks and multi-sensor fusion technology to achieve intelligent home security systems. On the control, the system is through the erection of the embedded Web server in the STM32, to completethe functions of remote access Web page, in order to control external devices; It is also available through the GPRS module, making the mobile terminal device control the system of connected devices via text message. From a functional point of view.the system is through the pyroelectric detection and camera module to complete the dynamic monitor of personnel,through infrared remote control circuit to complete remote control of appliances, through temperature and flame detection circuit to complete the fire alarm. Meanwhile, the system achievedthe information communication of the master and slavecontrol section through the wireless transmission, to avoid the inconvenience due to wiring, and enhance the ability of the system.The practical tests show that intelligent home security system based on networking technology proposed by this project is reliable, high degree of intelligence. In the debugging and testing, the system responses to the invasion of theft persons in time,obtaining accurate data from each sensor,it reached the experimental expectations,and proved the feasibility of the design. |
