  Fire emergency lighting and evacuation indication system

  1 Overview

  1.1 Fire emergency lighting and evacuation indication system setting necessity

  With the rapid development of economy and technology, people began to pursue the humanization and comfort of the building facilities. The emergence of a large number of high-rise buildings and underground buildings led to longer and more complex passages. In the people-oriented, life safety is the most important, for buildings with dense personnel, long evacuation distance, many evacuation channels, many corners, and complex environment, the evacuation indication method usually adopted is not very reasonable, not only high cost, but also inconvenient for inspection and maintenance. Can not be managed centrally. Therefore, the implementation of a rapid and effective safe evacuation system is an important measure to avoid mass casualties, so that the intelligent evacuation system came into being.

  In the planning and design of intelligent buildings and digital communities, it is required to ensure the interconnection and information of buildings and external information communication networks, and to receive, exchange, transmit, store, retrieve and display various information such as voice, data, images and multimedia. The various types of information equipments for comprehensive processing are combined to realize integrated management of application functions such as building business and management, and the original emergency lighting and evacuation indication system has been unable to realize real-time control of each emergency light point. There are phenomena such as hysteresis and power failure in the emergency state, and the fixed direction indicator and the safety exit sign mislead hidden dangers in the direction of the person leading to the dangerous area in the event of fire, which brings the effective evacuation of the crowd. difficult. As a result, unnecessary casualties have caused every insider to despise!

  The fire emergency lighting and evacuation indication system is a new type of product in the field of fire safety. Through the real-time monitoring and automatic maintenance of the safety performance of the emergency indicator light, it can effectively guide the crowd to evacuate and evacuate in time when the fire occurs, and support the life. "Protection umbrella."
