Design And Implementation Of Home Security Robot With Cloud Platform

With the development of society,increasingly importance has been attached to people's awareness of security and prevention,and the security of home has received extensive attention.Although the products of home security are developing rapidly,there are still many shortcomings,such as: cumbersome installation,aesthetic impact,difficult replacement,limited detection range,high false alarm rate,alarm is not timely,low cost performance,low level of intelligence and so on.For these problems,the existing security mode can not provide a unified and effective solution.This paper develops a home security robot,which integrates a variety of sensors,can collect a variety of safety information at home,and provide intrusion detection alarm,fire detection alarm,leakage detection alarm,gas leakage detection alarm and remote video monitoring.The robot which can cover most areas of the home environment by moving,expands the detection range of the sensor,and improves the utilization of the sensor.Based on cloud technology,this paper builds a cloud platform for home security robots based on Baidu Tiangong Internet of Things.Based on the material access technology,the network access of the cloud platform and the home security robot is established,and the functions of transmission,analysis,management and storage of security data are realized.According to the security requirements of the home environment,the security service rules are designed based on the rules engine.At the same time,in order to obtain a more friendly interactive experience,based on the object visualization technology,a visual JS interface was designed.Based on the MQTT protocol,data communication between the robot,the cloud platform,and the user is established.In this paper,the detection of gas leakage is optimized and an active olfaction suitable for home based on robot is proposed.The program is able to track the gas source through gas concentration information.The robot can actively find and confirm the leakage source according to the concentration gradient,so as to take effective measures to eliminate it in time.In this paper,the overall functional test of the home security robot system is carried out,which verifies the rationality of the theoretical analysis and the feasibility of the design.The results show that the home security robot can effectively complete certain home security tasks.
