[Abstract]:Smart home system is to achieve intelligent and comfortable life through Internet of things technology, embedded technology, network technology and so on. This paper starts with the current situation of smart home system, compares the research progress at home and abroad, and studies the bottleneck of smart home, and designs a front-end material sensing network based on Zigbee. The embedded ARM-Linux technology constructs the middle layer to realize the home intelligent control device RFID and the camera video capture V4L (video forlinux) technology to construct the access control system, the remote uses the Android technology, the Internet technology and the GPRS technology to realize the intelligent home system remote access and the control. The front end is based on Zigbee technology, supported by Z-stack protocol, combined with the multi-to-one relationship between the node and the coordinator, and equipped with smoke sensor, infrared sensor, temperature sensor, electromagnetic sensor on the node. Guang Min sensor and other building-up-related sensor network. The access guard verifies the usability of the user through RFID technology and database authentication, at the same time increases the video call technology, enhances the security and the user friendliness of the access guard. At the same time, the sensor data of the network is collected through the coordinator and transmitted to the ARM controller through the serial port in real time, and the data of the access terminal is transmitted to the main controller through the WiFi. At the control end, the necessary data is stored in the embedded Sqlite lightweight database by analyzing and classifying the data. In the process of data processing, the emphasis is on the data of the sensor network and access control. The main control terminal combines the needs of the user and the process of the program to judge the data, the level of temperature, the concentration of smoke, the strength of Guang Min, the interruption of infrared induction, and so on. When the value of the data exceeds certain conditions, Trigger anti-fire module, anti-theft module, and GPRS module, etc. At the same time, far end receives alarm message through GSM network or PC_WEB terminal receives alarm response through WiFi. Remote users can also access the smart home system through SMS, browser or client, view the data of node sensor, control household appliances through node, check the situation of entrance guard and so on. Finally, through on-line debugging, the relationship between the accuracy and distance of Zigbee transmission data, the stability of WiFi network, the accuracy of data at the control end and the real-time performance of remote data viewing are verified. Through the combination of theory and practice, this paper analyzes each module of home system in detail, which provides a new idea and reference value for building smart home system.
