1. Design defects of the traditional evacuation indication system

First of all, it is the problem of the design concept. In the past, traditional emergency evacuation indicator lamps and lanterns guided evacuation in fire in the way of "nearby guidance". In this way, once the building is built, the escape route has been determined.

However, the occurrence of fire is often unpredictable, and the spreading trend of fire is not invariable. Guiding people to escape by fixed escape path is bound to lead some people into the dangerous area filled with smoke.

In addition, it is easy for those who escape from the fire scene to have panic and blind psychology. Once the evacuation indicator marks point to the dangerous area, it may lead to unnecessary casualties.

Secondly, the objective adverse factors brought by the characteristics of the buildings themselves. For example, for high-rise buildings, if there are many floors and the vertical evacuation distance is longer, the time required for evacuation to the ground or other safe places should also be increased correspondingly.

Second, large scale, large number of people, unreasonable evacuation path setting, many corners, wide and narrow, easy to appear chaotic and crowded, affecting the safety of evacuation;

Third, during the construction, all kinds of vertical pipe Wells did not do a good job of fire separation treatment or treatment does not meet the relevant norms and requirements, smoke and fire pulling during the fire, leading to fast spread, to increase the difficulty of safe evacuation.

In addition, there are some problems in the emergency lights themselves, one of which is the loss and aging of the battery.

Usually this kind of problem appeared in the emergency lights did not focus on battery power, but by the emergency lamps and lanterns is built-in battery, when acceptance of work and can not find out the problem in time, and also won't appear in front of the building use few years of failure, but a few years later, as the built-in battery due to improper charge and discharge lamps and lanterns, aging problems, such as the occurrence of large area, and timely maintenance personnel, do not find fault and maintenance, eventually lead to failure, emergency lighting for staff to escape when the fire broke out great potential safety hazard.

Secondly, due to the different manufacturers of evacuation instructions and safety exit indicator lamps, the lamps have different styles and specifications, some fonts are too small, and some images are fuzzy and difficult to understand. All these problems will increase the difficulty of safe evacuation.

Other subjective factors also can cause bad influence on emergency evacuation, such as design personnel in accordance with the relevant specification design and cause no escape lighting illumination can not meet the standard, in the event of fire, in order to prevent electric shock and expand the fire electrical equipment, lines, need timely cut off the power of the fire area and the fire partition, if the emergency lighting does not have enough illuminance at this moment, people is easy to create chaos in the panic, with smoke, more difficult to accurately determine the best escape routes.

Intelligent evacuation indication system and traditional evacuation indication system

Intelligent evacuation indication system is composed of communication host (controller, with power), extension (regional controller), LED emergency evacuation lighting fixture, cable, etc.

Each terminal equipment in the system has its own address code. The system can inspect any terminal lamps online in real time and display the status of all terminal lamps.

When any equipment fails, it can send sound and light alarm signal. After troubleshooting, the alarm can be automatically eliminated.

The luminaires in the system also have the functions of strobe, voice, light out and so on.

Intelligent evacuation indicator system is superior than traditional emergency light is that when fire occurs, the system will be according to the linkage of the fire alarm system information, the system automatically generate the evacuation plan, namely fled the scene of the fire of the fastest, the best route, lamps and lanterns state of emergency immediately start stroboscopic, speech function, the indicator light is close to the dangerous area, open to AnQi area or safe evacuation passageway lamp, at the same time open emergency lighting lamps and lanterns, make people escape from the fire area at first.

Intelligent evacuation system to solve the traditional emergency lighting lamps and lanterns of battery aging, failure is unknown, exit indication lamps and lanterns also adding the function of voice, can also through the linkage information analysis, through stroboscopic, destroy the light function, make the best escape plan, so that it can effectively solve the high-rise buildings in the aspect of safety evacuation of many unfavorable factors.

3. Emergency process of intelligent emergency lighting evacuation indication system

Intelligent fire emergency lighting evacuation indicator system adopt fire evacuation indicator lights with different functions, combined with stroboscope, voice, two-way adjustable type, visual continuous light signs, escape from staff emphasized the senses such as vision, hearing, so that you can in the fire escape personnel safer, more accurate and more quickly.

Emergency steps of intelligent fire emergency lighting evacuation indication system: Step 1. After the fire is confirmed and the non-fire emergency special power supply is strongly cut off, all emergency lights within the scope of strong cut off will be turned into emergency lights and the emergency lights will be turned on.

Second, after receiving the confirmed linkage signal from the fire alarm equipment, the host machine changes the escape path direction of the corresponding emergency evacuation indicator light through the linkage logic. This step is the local optimization and adjustment of the fire evacuation path.

In case of fire, the escape path of the sign light shall be adjusted according to the fire linkage.

Voice, strobe and ground guided light flow are used to strengthen the guidance of personnel evacuation.

The linkage is based on the linkage signal of fire alarm, and the plan of evacuation and escape is started on the fire floor, the upper floor, the lower floor and the underground floor.

In large areas of public places such as supermarkets, shopping malls, airports, exhibition halls, hotels, hospitals, stations and garages, in the evacuation passageways, the adjustable guiding light can reduce the influence of smoke on the high sign lights in case of fire.
