Method for passage guidance and passage guidance system
The invention relates to a method for passage guidance by the aid of which particularly a person or several people, a group of people and/or like is being guided in a construction including internal rooms, such as in a building, an aeroplane, a ship and/or a like, along passage routes of the same from a starting point to a destination point, such as to an exit door, an emer¬ gency exit and/or a like, at least partly by exploi¬ ting an acoustic and/or a light emitting guiding system, that is connected by means of a computer aided arrangement at least to an auxiliary power source, such as a battery, a generator and/or a like to make sure the functioning of the guiding system under all circumstances.
The method and the passage guidance system applying the same may be adapted in most heterogeneous connec¬ tions starting from usual guiding purposes to catast¬ rophe situations with a view to evacuation carried out during such as fire situations, water injury situ¬ ations and/or the like.
Particularly with the safety lighting purposes it is known earlier to use a so called safety lighting arrangement, that is meant particularly to light up internal rooms of a building, such as exits particu- larly during disturbance situations of the line current such as electricity dropouts or the like, when the normal lighting is interrupted. The safety lighting arrangement includes usually a central unit, one embodiment of which is arranged inbuilt with a safety lamp to achieve a so called single safety lighting unit. The central unit belonging to such a single safety lighting unit comprises controlling and
monitoring means as well as auxiliary power means, whereby the controlling and monitoring means connected to the line current are arranged to activate and carry on operating of the safety lamp during interruption situations of normal lighting, such as during distur¬ bance situation of the line current by connecting the power input of the lamp to occur through the auxiliary power means. Usually the auxiliary power means compri¬ se a low voltage battery and a charger to load the battery. In addition to the principle of the above single lighting unit is known to form the said safety lighting arrangement alternately so, that the safety lamps that is usually for example glow bulbs or discharge lamps coupled to the safety lamp circuit in series or parallelly are connected to a separate central unit, which includes the equipment as been described above as an entirety.
Because of the purpose of the type of safety lighting arrangements described above, the functioning and principles of the same represent mainly primitive basic safety arrangements, because they are meant to operate during disturbance situations only, temporari¬ ly for safety lighting purposes, when the normal lighting is interrupted, or in certain type of appli¬ cations to operate always during the normal lighting for example continuously as direction lighting. Due to this kind of use either all the safety lamps or when adapting single lighting units each single safety lamp operates regularly always for example in connection with an electricity interruption. That is why with the type of arrangements above for example usual passage guidance may not be achieved, by means of which a person/a group of people to be guided is lead for example from one place of a building to an other place along the most optimal passage route. For such actual passage guidance it is nowadays known to use most
heterogeneous passive guiding arrangements, such as floor paintings, guiding maps or the like, the infor¬ mation and guiding functions of which remains essen¬ tially the same always.
It is the aim of the method according to this inventi¬ on to achieve a decisive improvement in the problems presented above and thus to raise substantially the level of knowledge in the field. To achieve this aim, the method according to the invention is primarily characterized in, that the said passage guidance system is being carried out by a so called optimizing guiding system, in which case the passage routes connecting the internal rooms and entrances/exits belonging to the construction are equipped with acoustic and/or light emitting guiding means, such as loudspeakers, lamps and/or a like placed one after an¬ other along the said routes, which are being control¬ led at least during an operational situation of the passage guidance system by means of a data processing unit belonging to the same, by the aid of which the most optimal passage route during the situation in question is being chosen and the guiding means along the corresponding passage route are being activated to guide the passage.
As the most important advantages of the method accor¬ ding to the invention, particularly the influence of the same improving the safety as a whole and the applicability of the same for different purposes and operational sites may be mentioned. First of all the invention enables thus usual passage guidance, whereby a route suitable for a person/a group of people is chosen for example at a control room or for example by means of a so called smart card in connection of the entrance, whereby following the chosen route the person gets to the desired destination. On the other
hand the method according to the invention may be adapted particularly during so called catastrophe situations, in connection of which the meaning is directly to evacuate rooms by leading everyone outside the construction or by moving people/groups of people in the building from one place to another to improve security. With the method according to the invention it is possible to exploit for example a monitoring system for monitoring of most heterogeneous characte- ristics in the operating site, in which case choosing of the passage routes may be carried out advantageous¬ ly in so called real time so, that for example corri¬ dors/rooms being damaged may be closed by means of an automatic central locking arrangement and the passage routes may be chosen by using usable internal rooms.
Advantageous embodiments of the method according to the invention are presented in the dependent claims directed to the method.
The invention relates to passage guidance system to apply the method, also. The passage guidance system is represented in greater detail in the preamble of the independent claim related to the passage guidance system. The primary characteristics of the passage guidance system are represented in the charac¬ terizing part of the corresponding claim.
First of all the passage guidance system according to the invention enables passage guiding, that is signi¬ ficantly versatile and usable than those nowadays arrangements, whereby by means of the same it is possible with simple arrangements to improve the safety of us of most heterogeneous buildings as well as for example of aeroplanes and ships as well as to improve passage guiding also in everyday use by utilizing nowadays adjustment and controlling techni-
ques. The most significant advantage of the passage guidance system according to the invention is the optimizing ability of the same, whereby the most suitable passage route may be chosen in each opera- tional situation by performing an analysis of the situation to activate further based on that only those signals placed along the chosen passage route. In this connection it is advantageous to use a light effect proceeding for example wavelike, by following of which the person may easily be lead to the direct address. On the other hand during catastrophe situations or the like it is advantageous to equip the system in a way, that for example at crossing points, end points and/or knot points of the corridors there are arranged separate auditive and visual signal devices, by means of which passage of the people is directed for example to a desired direction. In addition to that with a passage guidance system according to the invention it is also possible to adapt for example a so called central locking system, whereby the entry of the per¬ son/a group of people to be guided is disabled to unauthorized rooms. In this connection it is further possible to exploit most heterogeneous measuring devices and sensors to monitor for example the shape of the rooms and/or the circumstances in the building. On the other hand this enables also the real-time functioning of the passage guidance system as well as advantageously the adaptive functioning of the same, also, whereby, when applying for example so-called fuzzy logic, neuro-fuzzy logic and/or the like in connection with the data processing unit, the system by so called self learning determines for example additional operations and/or limitations during use.
In the following description, the invention is illu¬ strated in detail with reference to the appended drawings. In the drawings.

Method for passage guidance by the aid of which particularly a person or several people, a group of people and/or like is being guided by means of a passage guidance system in a construction including internal rooms I-XV, such as in a building, an aero¬ plane, a ship and/or a like, along passage routes i of the same from a starting point x to a destination point y, such as to an exit door, an emergency exit and/or a like, at least partly by exploiting an acous¬ tic and/or a light emitting guiding system. The guiding system is connected by means of a computer aided arrangement at least to an auxiliary power source la, such as a battery, a generator and/or a like to make sure the functioning of the same in all circumstances. The passage guidance system is being carried out by a so called optimizing guiding system 4, in which case the passage routes i connecting the internal rooms I-XV and entrances/exits A-F belonging to the construction are equipped with acoustic and/or light emitting guiding means 4', such as loudspeakers, lamps and/or like placed one after another along the said routes i, which are being controlled at least during an operational situation of the passage guidan¬ ce system by means of a data processing unit 1 belon¬ ging to the same. In this case by the aid of the data processing unit 1 the most optimal passage route i' during the situation in question is being chosen and the guiding means 4' along the corresponding passage route are being activated to guide the passage.
Further as an advantageous embodiment, the passage guidance system includes a monitoring system 2 being at least in a data transmitting connection with the data processing unit 1 and including monitoring devices 2a, such as sensors, processors, chips and/or like, placed at least in a part of the internal rooms I-XV and/or passage routes i. By means of these one or several characteristics, such as pressure, tempera¬ ture, number, flow, content of gas or water or humidi- ty and/or a like in the construction is being monito¬ red, which information is being transmitted further to the data processing unit 1 to determine the optimal passage route i' in so called real-time. Thus the passage of the said person, the group of people and/or the like from the starting point x to the destination point y may be guided as an advantageous embodiment by means of a sound and/or a light effect proceeding advantageously wave-like along the optimal passage route i' or correspondingly achieved by the guiding means 4 ' .
Further as an advantageous embodiment, the passage guidance system includes an actuator system 3 being at least in a data transmitting connection with the data processing unit 1 and that includes central locking arrangements 3a or like placed at least in a part of the internal rooms I-XV and/or passage routes i, such as in connection with doors, windows and/or correspon¬ dingly, whereby by opening/closing the doors, windows and/or the like at least along the optimal passage route i' the passage of the person/ people to be guided is enabled/ disabled. Further as an advant¬ ageous embodiment the passage guidance system includes indicator boards 3b, audio units 3c and/or like, placed at least at crossing points, end points and/or knot points of the corridors, by means of which at least auditive and/or visual notices, directions
and/or like are given at least along the optimal passage route i'.
A so called optimizing guiding system 4 applying the method according to the invention comprises, as shown in fig. 1 as a principal operating diagram, acoustic and/or light emitting guiding means 4' , such as louds¬ peakers, lamps and/or like placed one after another along the said routes i connecting the internal rooms I-XV and entrances/exits A-F belonging to the const¬ ruction, which are being controlled at least during an operational situation of the passage guidance system by means of a data processing unit 1 belonging to the same so, that optimally the most suitable passage route i' during each situation in question may be chosen, by activating the guiding means 4' along the corresponding route.
With reference to fig. 1 the passage guidance system includes further a monitoring system 2, which is formed of sensors, processors, chips and/or like, placed for example at certain internal rooms I-XV and/or passage routes i. By means of these one or several characteristics being monitored in the const- ruction may be transmitted further to the data proces¬ sing unit 1 to determine the optimal passage route i' in so called real-time. As an advantageous embodiment the passage of the said person/ people from the star¬ ting point x to the destination point y may be guided by means of a sound and/or a light effect of the guiding means 4' proceeding advantageously wave-like along the optimal passage route i' or correspondingly achieved by the data processing unit 1. Naturally when the guidance for one person or group of people at a time is going on, it is possible to couple the guiding means 4' to glow for example continuously and to cut off independently, when the guided ones reach their
destination y, whereby for example a monitoring sensor quits the guidance completed.
As an advantageous embodiment, the passage guidance system includes further an actuator system 3, that is formed of a central locking arrangements 3a placed at least in a part of the internal rooms I-XV and/or passage routes i. This enables at least opening/clo¬ sing of the doors, windows and/or the like at least along the optimal passage route i', to prevent an entry of the guided person/ group of people to unaut¬ horized rooms or to enable passage of the same along an optimal route i' .
Further as an advantageous embodiment, acoustic and/or light emitting indicator boards 3b, audio units 3c and/or like, are being placed at least at crossing points, end points and/or knot points of the corri¬ dors, to give notices at least along the optimal passage route i'. In this case it is possible to give additional instructions for example when guiding several people or groups of people simultaneously or to remove panic by giving detailed reports or recom¬ mendations.
As an advantageous embodiment the so called intelli¬ gent and advantageously self-learning data processing unit 1 controlling the functioning of the passage guidance system is arranged, for at least to enable trimming and/or maintenance of the passage guidance system as well as preferably the adaptive or self- learning functioning of the same, at least partly to exploit fuzzy logic, neural network logic, neuro-fuzzy logic, chaos theory, genetic algorithms and/or a like. This type of controlling is required, in case a more complicated construction is involved, whereby tradi¬ tional programming may not be utilized. The limit for
applying traditional programming techniques is met very soon, because even in case of significantly simple constructions a great amount of different kinds of regulations and connections must be taken into consideration, that may not be considered straightfor¬ ward when modelling entireties the way required by traditional programming techniques. Particularly in this connection it is particularly advantageous to exploit neuro-fuzzy logic, whereby primary adjustments determining the operations of the system are being determined by neural network logic, wherein those hereby determined adjustments are being exploited thereafter in the actual passage guidance of the passage guidance system carried out by fuzzy logic.
An advantageous embodiment is shown in fig. 2, whereby the quiding means 4 ' belonging to the passage guiding system 4 are formed of guiding strips 4'b extending in the longitudinal direction s, in which there has been placed by surface mounting techniques electrically connected leds, loudspeakers and/or the like one after another.
With reference to fig. 1, the guiding means 4', such as guiding strips 4'b of the guiding system 4 rep¬ resented in the same, are connected throughout to endless links, according to a loop or net principle and/or correspondingly. This means in practise, that transmitting of information in each passage route is enabled in two directions, in which case breakage of the guiding strip does not cause any problems as such, because the information may be transmitted the other way round.
It is obvious, that the invention is not limited to the embodiments presented or described above, but it can be modified within the basic idea even to a great
extent. Thus the monitoring system and the actuator system belonging to the passage guiding system as well as those separate actuators, measuring devices and the like of the same may be connected to the data proces- sing unit cordlessly for example by utilizing radio frequencies or optically. When applying the method according to the invention particularly for example with a view to passage controlling it is naturally possible to exploit for example figure and/or voice recognition or controlling and guiding automation based for example on use of so called smart cards or the like, which for example during a normal opera¬ tional situation enables the guided person to go along a certain route, only.
