| The system consists of a centralized controller, control node terminals and mobileterminals of three parts. System with wireless communication technology as a networktransmission infrastructure, proposed to wifi and2.4G wireless technology combinedsolution enables mobile phone with a centralized controller, centralized controller andcontrol node connection terminal to complete the home alarm detection of harmful gaseswireless operation control lighting control, appliance control, access control and curtains.Centralized controller is the core of the system, using the STM32F107as maincontrol chip, using the I/O port operation and serial communication methods to achievethe mutual conversion and WIIFI alarm signals and2.4G signal. Monitoring and controlsystem of the node is terminal objects, carbon monoxide detection system using carbonmonoxide sensor signal acquisition, through amplification and AD conversion. Therealization of the carbon monoxide content of the display and alarm. Appliances andelectric curtains analog infrared communication, to achieve the electric appliances andcurtains for remote operation. Lighting control system using I/O port mode of operationto achieve a light remote control, access control systems using serial protocol to achievethe remote control to it. Mobile control center of the system is interrupted, through thepreparation of a variety of user interface, remote control operation of the control nodeinterruption.The system of knowledge through WIFI communications technology,2.4Gcommunication technology, serial communication technology, infrared communicationand electronic circuits introduction of integrated applications, through theoretical studiesand market demand analysis, a set of simple, easy expansion and networking with acertain smart home system function solutions. |
