A directional continuous sound flow and lighting fire escape pointing method and system

Abstract

The invention discloses a directional continuous sound stream and illumination fire disaster escaping orientation method and a directional continuous sound stream and illumination fire disaster escaping orientation system. The system comprises a plan processing device and a plurality of sets of voice frequency and illumination guide devices. The plan processing device is used for sending various fire disaster escaping guide plans needed by each voice frequency and illumination guide device and receiving modification to the fire disaster escaping guide plans from an authority device; when fire disaster escaping guide needs to be carried out, the plan processing device can select a suitable plan according to real-time acquired fire field data information to generate a plan activation signal and transmit the activation signal out; the voice frequency and illumination guide devices are used for receiving the signal transmitted by the plan processing device in real time and judging whether the signal is the activation signal aiming at the equipment or not when the plan activation signal is received; if not, ignoring; if so, carrying out corresponding playing according to the fire disaster escaping guide plan indicated by the activation signal so as to form an indication of sound directivity and / or illumination directivity by the voice frequency and illumination guide devices of the same set.

Description

technical field [0001] The invention relates to the field of fire escape, in particular to a directional continuous sound flow and lighting fire escape pointing method and system. Background technique [0002] At the scene of a fire, because the current fire-fighting system immediately cuts off the ordinary power supply after detecting a fire, and relies on the emergency power supply to provide lighting. The lighting range provided by the emergency power supply lighting equipment is limited. At the same time, at the scene of a fire, the main threat to life is the thick smoke generated by the combustion. In addition to being poisonous, the thick smoke also greatly reduces visibility, making most people lose their way because they cannot see, and then encounter life-threatening poisoning. At the same time, thick smoke further reduces the lighting range of lighting equipment. Since the current fire protection system connects each sensor in a loop, if the loop is burned, the s...

The lighting range provided by the emergency power supply lighting equipment is limited

At the same time, at the scene of a fire, the main threat to life is the thick smoke produced by burning. In addition to being toxic, the thick smoke also greatly reduces visibility, making most people lose their way because they cannot see, and then poisoning encounters life-threatening

At the same time, thick smoke further reduces the lighting range of lighting equipment

Since the current fire protection system connects each sensor in a loop, if the loop is burned, the sensor connection will be lost, which will result in the inability to detect further information about the fire scene. People who escape often find that the road has been burned when they run to the escape route they are familiar with. blockade, or it is impossible to judge whether the route has been blocked by fire because of the thick smoke. If you look for other escape routes at this time, you will lose the chance of escape.
