Light guidance fire hazard evacuation system and light guidance fire hazard evacuation control method

Abstract

The invention discloses a light guidance fire hazard evacuation system and a light guidance fire hazard evacuation control method. The light guidance fire hazard evacuation system comprises a plurality of fire hazard sensing units, a fire hazard control host and a plurality of evacuation indication units and also comprises a plurality of cameras, wherein the fire hazard sensing units, the evacuation indication units and the cameras are independently wirelessly communicated with the fire hazard control host; the fire hazard control host receives and stores data sent from the fire hazard sensingunits or the cameras, judges whether a fire hazard happens or not and determines the position of a fire hazard site; and a Flyod algorithm is adopted to calculate an optimal path from a fire hazard area to each emergency exit, and the evacuation indication units are controlled for indication. By use of the Flyod algorithm, the optimal evacuation path is calculated, people can be evacuated from different emergency exits, so that evacuation time can be effectively shortened, and congestion accidents are avoided. A laser light and a bidirectional LED (Light Emitting Diode) indication light source are adopted to jointly serve as an evacuation indication sign, an indication effect is improved, so that people can quickly evacuate when smoke is thick, and therefore, evacuation efficiency when the fire hazard happens can be greatly improved.

Description

technical field [0001] The invention relates to the field of fire evacuation, in particular to a light guide fire evacuation system and a control method thereof. Background technique [0002] At present, the existing fire safety facilities in large public places generally use safety evacuation indicator signs, which adopt traditional LED and gas lamps to emit light for the crowd to realize the instructions of safe exits. [0003] However, the traditional LED and gas lamps are small in size and small in number, and the light emitted by them has poor penetration and low illumination in the fire space where the smoke is thick. Ignored by the crowd, it cannot play a good role in indicating lighting. And the light emitted by most of the LED and gas lamps is fixed to indicate the direction, that is, the indication direction and evacuation indication route of the evacuation indication signs are fixed, not eye-catching, and the directivity is not strong. When the crowd escapes to t...

[0003] However, the traditional LED and gas lamps are small in size and small in number, and the light emitted by them has poor penetration and low illumination in the fire space where the smoke is thick. Ignored by the crowd, it cannot play a good role in indicating lighting

And the light emitted by most of the LED and gas lamps is fixed to indicate the direction, that is, the indication direction and evacuation indication route of the evacuation indication signs are fixed, not eye-catching, and the directivity is not strong. When the crowd escapes to the safety exit with the signs When the fire occurs in the safety evacuation route or near the safety exit, the crowd will be closer to the fire area when escaping along the evacuation signs, and more serious safety accidents may occur
