In addition, in order to prevent the common conduction of the utility power output and the emergency output during the switching process of the utility power and the emergency output, the actuation relay needs to be turned off first, and then the corresponding relay is actuated after a set time, for example, the first output relay 281 is turned off first, and the second output relay 282 is actuated after 10 ms.
The second emergency lighting centralized power supply 30 and the third emergency lighting centralized power supply 40 are similar to the first emergency lighting centralized power supply 20, and can continuously supply power to output low voltage 24Vdc or 36Vdc, so that the discussion will not be repeated.
In the invention, the system adopts advanced bus communication, the fire emergency lamp and the equipment are connected to form the fire emergency lighting and evacuation indicating system, and the emergency lighting controller 10 can continuously monitor the working states of the terminal lamp and the equipment of the system in real time throughout the day. When a fire disaster occurs, the emergency lighting controller can be linked with the fire disaster alarm system to automatically acquire the position information of the fire disaster alarm point, automatically calculate the optimal evacuation route, automatically adjust the evacuation route according to the continuously changed fire disaster information, and control the corresponding emergency lighting lamp and the marker lamp to start, so that people on the fire disaster site can be evacuated rapidly through the optimal route, the aims of safely, accurately and rapidly guiding the people to avoid danger and escape are achieved, casualties are avoided to the greatest extent, and the problems of fixed direction, unsatisfactory indication effect, high maintenance cost, poor safety performance and the like of the traditional evacuation system are effectively solved.
The system has the characteristics of safety, high reliability, wide applicability and the like, and can be widely applied to various high-risk fire places such as petroleum, chemical industry, medicine, factories, wine making, urban underground pipe galleries and the like.
