The emergency lighting centralized power supply is to merge all emergency lighting control emergency start power sources into one system, so that it can be started in time. There are many power supply methods for emergency lighting, including grid independent power supply, diesel generator set power supply, and battery power supply. Generally used for emergency events, for example, it can be linked with a fire alarm in the event of a fire, and it can be used as emergency lighting when the power is out of accident. There are three emergency lighting control methods, namely, emergency lighting fixtures are turned on 24 hours a day, emergency lighting fixtures are all powered by their own batteries, and emergency lighting fixtures can be used simultaneously with other lamps. The advantages of centralized power supply for emergency lighting: 1. Safe voltage power supply-The fire emergency lighting uses DC24V power supply. The DC24V power supply system is called "uncharged system". Compared with the traditional emergency lighting lamps using 220V power supply, the safety is greatly improved. 2. Low accident risk and low maintenance cost-the battery central station type power supply system has the risk of complete power failure. The battery maintenance and replacement of the self-powered fire emergency lighting is inconvenient, and the operating cost is high. The advantages of decentralized centralized power supply are very obvious . 3. Realized the transition from "nearest evacuation" to "safe evacuation"-it can be linked with fire alarm to quickly and accurately obtain the location information of the fire point. At the same time, the computer automatically generates the evacuation plan and controls the fire emergency signs The lights indicate the best evacuation route.

1. When a fire occurs, the system can change the direction according to the location of the fire point, and guide the masses to evacuate away from the fire point. ①When the fire point is close to the exit of the corridor, the evacuation exits on the floors above the exit must be displayed closed, so that the crowd can avoid danger and evacuate to the exit near the fire point on the fire floor. ② People on floors below the fire point can be evacuated to any exit to achieve the purpose of evacuation as soon as possible. 2. The fire scene is full of smoke, and the traditional evacuation indicator will be unclear at this time; this intelligent system can use voice, strobe and other function prompts when approaching or reaching the exit to warn the evacuees, avoid missing the exit, and ensure rapid evacuation. 3. The intelligent system can perform self-inspection and patrol inspection of various indicator lights and emergency lighting fixtures online in real time at ordinary times. Alarm, display, and record the information (lamp number, communication address, fault status) of the malfunctioning lamp.

In actual construction projects, the choice of emergency lighting centralized power supply should be based on the number of floors of the building, the size and complexity of the building, the number of people staying and moving in the building, the characteristics of production and use in the building, the degree of disaster risk, and the importance of the building. The level of emergency lighting and the settings of other emergency power sources, etc., are comprehensively considered and compared with technical and economic analysis, and the emergency lighting centralized power source is selected.
