Development Of Intelligent Fire Detection System For Intelligent Building

The rise of Internet of things technology promotes the wireless sensor network technology more networked and provides new ideas and more ideal solutions for the implementation of security fire detection system of intelligent building. Compared with traditional security fire detection system, the system using Internet of things technology has obvious advantages:simple wiring, easy transformation, easily maintenance; it could realize remote monitoring and could be used in many occasions.The thesis chose wireless sensor network technology to set up network and embedded microprocessor as the control center of the system. This thesis designed an intelligent building security fire detection system based on Internet of things technology. This thesis complete the hardware circuits of main control center,. data acquisition terminal and remote alarm module. The thesis use embedded technology to design software. The thesis transplanted the boot loader, kernel, driver, root file system and set up the embedded Linux operating system. The thesis used the embedded development tools to design each module of the program. The design of wireless sensor network node program realized of the security and fire data acquisition, wireless transmission and site response. The program design of main control center realized of image collection and preservation depend on the video interface. The program design of embedded Webpage server created the dynamic Webpage based on the dynamic script and realized human-computer interaction function. The program design of GSM module realized remote SMS alarm function. The thesis finally completed the design of practical alarm monitoring device and realized the remote monitoring and alarm functions of fire security information in the building.According to the basic functions of the device to achieve, the project conducted remote webpage monitoring and SMS alarming tests. The test results show that this device realized the basic functions of intelligent building security fire detection system based on the Internet of things, monitoring and alarming.
