The Design Of Home Environment Monitoring System Based On Android Platform

With the improvement of national economy and the rapid development of science and technology level, people more and more eager to get a good living environment, and people in indoor time accounts for people's life in the most, so indoor environment whether let people feel comfort, safety, directly affect the ringing people's health and quality of life. Through the analysis of the influence of people's health and safety of indoor environmental factors such as indoor lighting, ventilation, temperature and humidity conditions and some risk factors such as gas leakage, fire hazards and other issues. In recent years the rapid development of the theory and technology of Internet of things, the use of wireless sensor networks, automatic control technology and network communication technology and the development of mobile technology in order to meet the requirements of indoor environmental monitoring at the same time, can realize remote real-time display, has gradually become the development trend of the indoor environment monitoring technology.This paper designs a kind of indoor environment monitoring system based on Android platform. On the one hand, the system can realize the real-time display on the mobile phone users, on the other hand also can in environmental parameters exceeds the value set in the system security, can through the mobile phone push send timely delivery to mobile phone users.The system is mainly composed of the following parts: the data collection of Internet of things, the cloud server and the design of Android terminal APP. First, in order to collection to some of the effects of health parameters, use in recent years, the development of rapid networking technology, using ZigBee technology nodes arranged in the interior of each position consisting of indoor wireless sensor network and each node of the data through the radio frequency antenna will transmits the data to the coordinator, the Coordinator by calling the API interface to the data is sent to the home gateway. The home gateway can access the Internet network through the network cable, then communicate with the data server on the Ali cloud, and store the data on the home gateway through the network to the database in the server. Finally, you can phone APP application through the HTTP protocol and Ali cloud server communications, and will receive data from the cloud server to send real-time display. If you encounter dangerous situations such as fire, gas leak, the server will push the alarm information to the phone APP side, the user can be notified in a timely manner..
