Definitions
- Generic fire/gas alarm systems comprise a number of components including devices such as smoke, heat, and gas sensors, indicators of emergency situation, manual alarm input, audible and visible notification devices, and actuator.
- Indicators range from audible devices such as speakers, bells, horns, sirens, etc., to visual devices such as incandescent lights, strobe lights, illuminated exit signs, informative panels visualizing useful information, e.g., fire and evacuation plans for the occupants, etc. Furthermore, actuators comprehend electromechanical and electrical devices for automatically fire doors closing, gas closing, etc.
- a first solution for a generic fire alarm system consists of a number of horns, bells, sirens, and/or vocal message devices, which are placed strategically within the premises and are connected to the alarm system control panel. Upon the detection of smoke, gas, or fire, the audible devices would activate and would be useful as audible indicators for an emergency situation.
- a second solution for a generic fire alarm system consists of a number of strobe lights and visible indicators which are placed strategically within the premises and are connected to the alarm system control panel as visual indicators for an emergency situation.
- visible indicators we could think also about directional devices such as serpentines of lights with the aim to guide the occupants.
- a third solution derives from the complementarity of the two aforementioned solutions and it has the scope to combine both of them.
- numerous visible devices have a different impact than audible devices.
- strobe light can better notify deaf people or with hearing disability about an emergency situation.
- light is more effective particularly in nighttime situations or in darkness, or when the occupants are outside the audible devices' range. This is especially true in presence of malfunctions of the audible devices.
- many fire alarm systems include several strobe lights. Vice versa is also valid.
- Placement of devices in premises is determined by several factors such as building plans, entrances, room locations, lifts, exits, fire walls, fire doors, etc. Furthermore, some buildings have a greater capacity to reflect sounds and lights.
- the primary goal of a generic fire alarm system is to alert occupants and let them evacuate or guide them to safety.
- One or several alarm tones or pre-recorded voice messages together with flashing lights may achieve this purpose, but it may not be sufficient.
- the fire alarm evacuation system is arranged to compute, for each interesting physical place of the building, the minimum evacuation path, or towards safe areas, minimizing the occupants flows, with the intent to address and lead people in the shortest time to exits or safe areas without generating congestion.
- a graph G is generically defined by a set of nodes or endpoints N and by a set of arcs or edges A .
- An edge has two endpoints in the set of nodes, and is said to connect the two nodes.
- An edge can thus be defined as a set of two nodes.
- a directed arc, or directed edge is an ordered pair of endpoints that can be represented graphically as an arrow drawn between the nodes.
- the first vertex is called the initial vertex or tail; the second one is called the terminal vertex or head (because it appears at the arrow head).
- An undirected edge disregards any sense of direction and treats both endpoints interchangeably.
- a directed arc a (i, j), with node i as tail and node j as head of arc a .
- a possible modeling for our application domain can be represented by a graph G defined by:
- the minimum cost flow is a really general optimization problem on networks: both the maximum/minimum flow problem and the shortest path tree problem can be interpreted as particular cases of the minimum cost flow problem.
- the shortest path tree constitutes a modification to the model for the search of the minimum path between two nodes.
- the set of all shortest paths from a node r, the root, to all the other nodes in the graph can be computed.
- Such a set of the shortest paths is called shortest paths tree of root r. It is called tree because loops are not present.
- the maximum/minimum flow problem consists in finding the maximal/minimal flow that can be sent from one source node to one sink node (as explained hereafter), respecting the edge capacities and not allowing dispersion within the intermediate nodes.
- the node balances govern the network flow.
- a flow must satisfy the restriction that the amount of flow into a node equals the amount of flow out of it, except when it is a source, which has more outgoing flow, or sink, which has more incoming flow.
- sink nodes can represent exits or safe points in the premises.
- Source nodes can represent places within the building where people stay or are detected by adequate devices.
- the minimum cost flow consists determining, in a flow network, the maximum amount of flow on the network edges such that all the flow would be inputted from the sources, all flow would arrive to the sinks, the edge capacities would not be exceeded, and the overall flow cost would be minimum.
- the shortest paths tree e.g., finding the shortest evacuation path from a generic point of interest
- the maximum/minimum flow problem in the more general formulation can be considered as a minimum cost flow problem. In fact, all the node balances are zero. What makes convenient to let circulate flow with respect to the null solution is the objective function.
- maximal/minimal flow we can fix all the edge costs to zero but for the fictitious return edge (t,s), where s is the source, which we fix a cost of -1 for. In such a case can be found an evacuation path maximizing/minimizing the flow from a source node to a sink node, as an exit or a safe meeting point.
- an emergency alarm system comprising: (1) a controller, (2) a plurality of detectors and/or manual alarm inputs, (3) a plurality of audible and/or visible indicators (in general indicators of an emergency situation), (4) a plurality of actuators, (5) and/or a plurality of movement sensors and presence indicators.
- Movement sensors and presence indicators are connected to the system and they can serve as detectors of occupant flows. In case of movement sensors they can serve as automatic detection of individuals, while for presence indicators, we can think about manual input indicators triggered by individuals trapped into a location. Furthermore, as presence indicators can be thought also smart phones and tablet PCs connected to the central system requiring for rescue.
- One audible or visible device can belong to one or more typologies. For instance, it can be a speaker both informative, whereas provides an information about the emergency location, and directional, since it provides an evacuation direction.
- an emergency alarm system is provided with multiple functionalities:
- evacuation paths towards safe points are dynamic, since are computed for all points of interest "in alarm”.
- evacuation paths depend both by the initial place/s of the emergency (e.g., fire, gas, etc.), and by its/their propagation.
- the emergency alarm system comprising all hardware and software means for carrying out the several aforementioned functionalities.
- an embodiment in accordance with the present invention provides a controller (310) managing the entire alarm system having a memory (320) where will be stored all the needed information to let the system work, i.e., the points of interest, the safe points, the graph, the identification addresses and their connection to the points of interest, etc.
- the alarm system is provided with a set of manual alarm inputs and smoke and/or gas and/or heat detectors (330).
- the system has a multiplicity of actuators (360), audible indicators (335), and visible indicators (345).
- movement sensors (370) are connected to the system and they can serve as automatic detectors of occupant flows; also, presence indicators (370) are connected to the system and they can be considered like manual input indicators triggered by individuals trapped into a location, or also like smart phones and tablet PCs connected to the central system (310) requiring for rescue; furthermore, both movement sensors and presence indicators (370) may provide indications, whenever the firemen arrive, about the locations where still some occupant is present or trapped.
- the evacuation alarm system (300) evacuation system is arranged to compute the minimum evacuation path, or towards safe points, minimizing the occupants flows, with the intent to address and lead people in the shortest and timely time to exits or safe points without generating congestion.
- the alarm system (300) is also arranged to react dynamically to the evolution and spread of the emergency, with the aim to lead occupants to safe points.
- the controller (310) can be connected via a network connection (e.g., a secure internet connection) and provide a functionality for generic emergency situations. In such case firemen could activate the evacuation system remotely, for example in circumstances of dangerous environmental situations (e.g., earthquake, etc.).
- a network connection e.g., a secure internet connection
- firemen could activate the evacuation system remotely, for example in circumstances of dangerous environmental situations (e.g., earthquake, etc.).
- the emergency alarm system (300) may provide guidance that allows safe passage or facilitates locating civilians.
- the occupants can be directly informed by the controller (310) about an evacuation path using views or graphical user interfaces visualized on tablet PCs or smart phone owed by the occupants. for instance, an application could be downloaded by the user with the plan of the building.
- the systems communicates directly with the application on the user's smart phone. In such a way, the system is aware if some individual is still trapped within the premises.
- the initializing phase is enough to let occupants evacuate.
- all devices of all typologies i.e., general, informative, and directional
- the evacuation paths are signaled according to the paths already stored at step (440).
