[Abstract]:As an important application field of Internet of things, smart home system has put forward higher requirements for convenience and reliability of Internet of things technology, mobile terminal function development, home intelligent control based on cloud server, etc.The aim of this paper is to design a smart home system which combines wireless sensor network and mobile robot.First of all, through investigation and analysis of relevant literature, the research significance of smart home system, determine the structure of smart home system, clear the content of the paper.Then, the technical characteristics of C luster-Tree and AO DVjr zigbee routing algorithms in the network are analyzed. In view of the shortcomings of the above two algorithms, the paper improves the AODVjr algorithm by combining the node energy and Cluster-Tree algorithm characteristics.The network energy consumption, the number of dead nodes and the correct rate of data transmission in NS2 simulation of AODVjr algorithm before and after improvement under linux system platform are compared and analyzed.According to the application requirements of smart home, the improved AODVjr routing algorithm can choose the best path dynamically and save and balance the energy consumption of the nodes.Then, the mobile robot in the smart home interconnects with the zigbee wireless sensor network in the smart home by serial port communication mode, and interconnects with the server through the socket socket mode to realize the interconnection between the robot and the smart home network.This paper studies the development methods of mobile robot's functions such as line patrol, autonomous obstacle avoidance, grasping objects, mobile video monitoring and so on, and realizes the corresponding functions in the simulated home robot.In addition, the realization method of smart home based on mobile intelligent terminal and cloud server is studied. In the smart home system, the mobile intelligent terminal APP is designed and the cloud server is built to realize remote mobile control.Finally, the improved AODVjr algorithm is used to build the home network through the Zigbee wireless sensor network, and the network effect of the improved AODVjr routing algorithm is verified.In addition, the data verification, intelligent control, communication between intelligent terminal and server, connection of camera and the whole smart home system are tested.Verify the feasibility of each part of the smart home system.
