Intelligence Dottype Control Fire Emergency Lighting And Evacuation Instructions System

With the rapid development of science and economy, the buildings tend to be taller andcomplicated. At the same time, the fire accidents occur frequently. Due to the lack of intelligencein the traditional fire evacuation instructions system, it can not meet a series of requirements of“Fire Emergency Lighting and Evacuation Instructions System”, according to the nationalstandards of the People’s Republic of China (GB17945-2010).Therefore, the research for thenew intelligent evacuation instructions system has important significance and broad market value.According to the requirements of (GB17945-2010), this project designed a fire evacuationinstructions system. It can monitor2000intelligent lightings in real-time with a monitoring host.The system has a series of functions, such as testing, fault alarm and programmable plans.Also, itprovides the hardware interface that connects the linkage signal of fire and the space for thesoftware’s upgrade.And finally, it comes to be a intelligent system. So it is called intelligent fireevacuation instructions system. According to research, this project ultimately determined CANbus as the communication bus for the intelligent fire evacuation instructions, C8051F040microcontroller as the control chip and VB as PC development software.After a series ofexperiments and debugging, it ultimately proofs that the design of the intelligent fire evacuationindicating system is reasonable and reliable. And finally, it is permitted to put into productionafter audited by national patent offices.This project made a specific studies for how to calculate the best escape route in the firescene.The system uses the Dijkstra’s algorithm to make the model and simulation and calculatethe escape routes according to the algorithm, which is very convenient for the operation of theevacuation indicating system.
