application example 1

[0177] Used in commercial facilities, hotels, multi-storey offices, multi-purpose complex buildings, conference venues, hospitals, theaters, universities, factories, multi-storey or super high-rise apartment buildings, terminal buildings, underground shopping malls, ships, individual-owned housing, etc. The economically active or resident population is large, and in the event of a fire, when the number of people there is unknown, the panic caused by smoke, flames and gases is severely affected.

[0178] The digital smart security system 1000 provides a system that grasps a fire in real time and enables an unspecified number of people living in a building facility to safely evacuate without an accident. The system enables relevant personnel to accurately guide evacuation, and residents evacuate to stairs, evacuation facilities, and entrances / exits in order of proximity in the opposite direction to the fire site based on the fire situation.

[0179] First, evacuation guidance of...

example 1

[0184] In this case, all smoke detectors SM1 to SM10 on the floor of the facility detect smoke. The volume of detected smoke increases in the order of smoke detectors SM3, SM2, SM1, SM6, SM5, SM4, SM7.... as by Figure 7 As indicated by the outline arrows in , smoke can be determined to flow generally in a direction from the west to the east of the commercial facility. Focusing on the volume of smoke detected by the smoke detectors SM6, SM5 and SM4, a portion of the smoke can be determined to flow from south to north. In addition, it is assumed that the flow speed of smoke is determined to be higher in the direction westward from smoke detector SM3 ("smoke flow direction" A) than in the direction westward from smoke detectors SM2, SM1 ("smoke flow direction" B, C) Up high. First, from these determination results, the monitoring device 100 determines general smoke flow directions, that is, "smoke flow direction" A, "smoke flow direction" B, and "smoke flow direction"C. Then...

example 2

[0187] Here, when the smoke flow velocity is very high, the fire may already spread rapidly in this direction. In this case, the monitoring device 100 directs the evacuation in a direction avoiding higher smoke flow velocities. This is described in detail below.

[0188] exist Figure 7 In , it is assumed that there is a case where the velocity of the smoke in the "smoke flow direction" A has become rapidly high. However, this smoke volume is comparable to the smoke volume in the "smoke flow direction" B. In this case, the fire is determined to spread rapidly in the "smoke flow direction" A, and in order to ensure future safety, the evacuation guidance in the "smoke flow direction" A is switched to the "smoke flow direction" Evacuation guidance on B. In the present embodiment, the smoke velocity is also used as a factor for determination, and without determining the smoke velocity, the "smoke flow directions" A and B cannot be distinguished from each other based only on th...

Abstract

Provided are a digital smart safety system, method, and program which are capable of safely guiding the evacuation of persons in the premises during a fire. This digital smart safety system (1000) isprovided with: a smoke determination means (112) which, on the basis of smoke information detected by a plurality of smoke detectors (234) installed in the premises, determines the flow direction, amount, and speed of smoke; an air blower which is installed in a smoke diffusion site including openings such as windows or smoke vents around the exterior, and sets the air blowing direction on the basis of the determination results of the smoke determination means; a fire door detection means (113) which detects that fire doors / fire shutters (228) provided to the premises are not closed; a persondetection means (114) which detects persons who have failed to escape during a fire; and a control means (115) which, on the basis of the determination results of the smoke determination means (112),implements evacuation guidance control in which a safe site is specified, and the evacuation of relevant persons in the premises is guided.

Description

technical field [0001] The present invention relates to a digital intelligent security system, method and program that monitors the status of a facility and safely guides evacuation of persons related to the facility from fire or suspicious persons by receiving information from safety-related equipment installed in the facility. Background technique [0002] Scale expansion and concentration of buildings and facilities and multi-story housing are increasingly promoted. For example, adulteration of commercial facilities, hotels, multi-storey offices, multi-purpose complexes, conference venues, hospitals, theaters, universities, factories, multi-storey or super high-rise apartment buildings, terminal buildings, underground shopping malls, ships, individual-owned housing, etc. Both sex and complexity are remarkable. [0003] Measures for safety and convenience are extremely important, and complicated safety measures have been required. The resident population in large facilit...
