The Application Research Of A Indoor Wireless Fire Detection System Based On Wi Fi

In recent years,the smart home market is booming,and smart home devices are becoming more and more popular,which brings people a lot of convenience.Smart home devices are gradually replacing non-smart home devices that provide similar functionality.In the field of home fire and security-monitoring,many domestic and overseas companies have pushed out new smart smoke detectors which are very innovative both in appearance and functionality.With the development of smart home and mobile Internet,developing a new smart smoke detection and alarm system which can connect to mobile terminals by the mobile internet has a strong practical significance.This paper designs and implements a indoor wireless fire detection and alarm system based on the existing photoelectric smoke senseor ? temperature sensor and carbon monoxide sensor. The entire alarm system consists of the smoke, temperature and carbon monoxide composite fire detector based on Wi Fi, Ali cloud server and smart phone. The composite fire dectector based on CC3200 uses Wi Fi to connect and communicate with Ali cloud server. It can also adjust the chip operating mode and smoke detection strategy to reduce the detector's power consumption effectively. Ali cloud server implements the communication between composite fire detectors and smart phones based on ubuntu operating system, python and twisted framework. Smart phone connects and communicates with Ali cloud server based on Wi Fi or data network. Smart phone can request status information of a composite fire detector and receive alarm messages sent by a composite fire detector via APNs in case of emergency.After the entire detection and alarm system is implemented, this paper tests the functionality of fire and carbon monoxide, the functionality of receiving alarm messages on smart phone, the forwarding feature and logging of Ali cloud server, the performance and stability of the entire detection and alarm system. The result shows that the detection and alarm system can run stably, and the system features and performance are in line with the requirements.
