Research and design for emergency evacuation instructions system based on wireless sensor network

In order to achieve the goal of centralized control and emergency evacuation instruction for the current emergency lights system, also to overcome the disadvantages of the traditional emergency lights system such as uncontrollability, unobservability, and instability, we propose a construction on an emergency evacuation system by using the technology of wireless sensor network in this paper. The system firstly collects the real-time status of the light by sensors, and then the data are transmitted to the control center through the wireless network. After that, it can monitor the state of light and give emergency evacuation through corresponding algorithms. In this way, the emergency lights system become controllable and observable. At the same time, it reduces the installment, management and the maintain cost, while improve the stability of the emergency lights.
