Description

Dynamic and/or adaptive escape path indicating system

Technical Field

The utility model relates to a developments and/or self-adaptation route of fleing indicating system to and a system that is used for developments and/or self-adaptation ground to instruct route of fleing.

Background

Safety indicators allow people to quickly and safely leave a building in an emergency such as a fire. Such safety indicators are visible even when the general electrical lighting of the building fails.

One example of a safety indicator is a safety marker light by which an escape or rescue path for leaving a building is indicated to people. Such safety marker lights are often light-emitting pictograms showing stylized runners and rescue path pointing arrows, but may also include other markers (e.g. the wording "EXIT"). In this case, the pictograms are static and are, for example, glued, inserted or printed on the label.

One problem with these systems is that static pictograms may introduce people directly into a dangerous situation, such as a smoke-filled room.

To solve this problem, dynamic safety indicators are known in which a part of the safety marker lights are designed as liquid crystal indicators (LCD) or LED indicators. The latter is for example in the form of a matrix of LEDs or by means of coupling of LED light into a light guide plate. The rescue path pointing arrow is displayed with these indicators, wherein the arrow direction can be adjusted by controlling the indicators. For example, based on smoke detector data.

However, known dynamic security indicators have problems. On the one hand, the arrows displayed with these indicators often do not comply with the regulations and standards in terms of shape, color or brightness of the security symbol (EN1838, ISO7010, ISO 3864). On the other hand, a failure of the internal power supply of these indicators can result in no longer any display being displayed on the display screen, but a simple printed pictogram can still be recognized, for example, in the presence of sunlight.

It is therefore an object of the present invention to provide an improved escape path indicating system and an improved system for dynamically and/or adaptively displaying an escape path, which eliminate the above-mentioned disadvantages of the prior art. In particular, the object of the invention is to provide a dynamic and/or adaptive escape route indicating system which enables a graphical display even in the event of a power interruption to the system.

These and other tasks which will be mentioned in the following description or which will be recognized by the skilled person are solved by the subject matter of the independent claims. The dependent claims develop the central idea of the invention in a particularly advantageous manner.

SUMMERY OF THE UTILITY MODEL

According to a first aspect, the present invention relates to a dynamic and/or adaptive escape path indicating system comprising: at least one sensor designed to detect an escape path-related physical quantity; at least one escape path sign, the escape path sign comprising a dynamic indicator, wherein the dynamic indicator is designed to maintain a displayed graphic in the power-off state; a control unit, which is designed to determine a control signal depending on the escape path-related physical quantity, wherein the control unit is further designed to control the at least one escape path sign with the control signal such that a complete or partially pre-stored graphic is displayed on the dynamic indicator. The following advantages are thereby achieved: a particularly safe and reliable escape path indicating system is created.

In particular, the at least one dynamic indicator can then display a graphic even if the power supply to the system, in particular to the escape path sign, is interrupted. Furthermore, the use of pre-stored graphics enables the reliable, rapid display of standardized graphics that are easily recognizable.

Detailed Description

Fig. 1 discloses a schematic diagram of a preferred embodiment of a dynamic and/or adaptive escape path indicating system 10.

The escape route indicating system 10 includes: at least one sensor 11a-c, which is designed to detect an escape path-related physical quantity; at least one escape path sign 13a-c comprising a dynamic indicator, wherein the dynamic indicator is designed to maintain a displayed graphic in the power-off state; a control unit 15 which is designed to determine a control signal depending on the escape path-related physical quantity, wherein the control unit 15 is further designed to control the at least one escape path sign 13a-c with the control signal to display a complete or partially pre-stored graphic on the dynamic indicator 21.

The dynamic and/or adaptive escape path indicating system 10 can display the escape path to people by means of the escape path sign according to the quantity detected by the sensor. It is thus possible to guide people away from an environment, for example a building, on a particular escape route.

For example, the dynamic and/or adaptive escape path indicating system 10 comprises a plurality of escape path signs 13a-c, which represent a stylized graphic and an escape path pointing arrow on their dynamic indicators, each on a green background. The direction of the arrow can be dynamically adjusted according to the control signal.

According to one embodiment, the control unit 15 comprises a logic unit 17, for example a processor. The logic unit 17 may be designed to determine the control command. The logic unit 17 may be implemented as software.

Dynamic and/or adaptive escape path indicating system 10 may also include a central battery system 14 or a central power system in the form of another central power source (e.g., diesel powered or secondary power grid, etc.). The battery system may be designed to supply the escape path signs 13a-c, the sensors 11a-c and/or the control unit 15 with power. In another embodiment, the control unit 15 may at least partly comprise a central power supply system, in particular a central battery system 14.

According to one embodiment, the escape path indicating system 10 comprises a plurality of sensors 11a-c, which are each designed to detect an escape path-related physical quantity. The control unit 15 can be designed to determine the control signal for each escape path sign 13a-c on the basis of the detected escape path-related physical quantity.

The sensor is for example a smoke detector, from which the control unit 15 or the battery system 14 obtains information of which rooms of the building are filled with smoke. The sensors may also include a camera sensor that can not only identify flames, but also whether or where a person is staying indoors.

Fig. 2 shows a schematic view of a preferred embodiment of the escape path sign 13.

The escape path sign 13 may comprise a dynamic indicator 21 in a housing 23.

The dynamic indicator 21 may be a reflective or transflective display screen. The dynamic indicator 21 may also be a bi-stable indicator that requires power only when the display content of the display screen is changed.

According to one embodiment, the dynamic indicator 21 is an electronic paper display screen.

The dynamic indicator 21 may be a multi-color indicator, in particular a multi-color electronic paper display screen. This allows pictograms and warning cues to be displayed in colors that meet the criteria.

The multi-color indicator may be designed to display at least eight colors, in particular green, white, red, yellow, blue, orange, violet and black. By limiting to the most important colors, the dynamic indicator 21 can be produced cost effectively. At the same time, the resolution of the dynamic indicator 21 can be improved by a special color Mixing method, so-called Pixel Mixing.

Static or dynamic graphics may be displayed using the dynamic indicator 21. Static graphics are, for example, pictograms or text that do not change over time. The dynamic graphics are, for example, flashing display content, such as flashing arrows, or video.

The dynamic indicator 21 of the escape route sign 13 shown in fig. 2 includes a first display area 21a and a second display area 21 b. The dynamic indicator 21 may be designed to display different graphics in the first display area 21a and the second display area 21b in response to a control signal, for example a pictogram in the first display area 21a and a text or a flashing arrow in the second display area 21 b.

The escape route sign 13 may further have an illumination device 25. The lighting means 25 are, for example, LED front lighting means and may be arranged such that the dynamic indicator 21 is illuminated as completely as possible. Especially when the dynamic indicator 21 is implemented as a reflective electronic paper display screen, readability may be improved by the front lighting means.

Alternatively, the illumination device 25 may also be arranged behind the dynamic indicator 21. In particular, the dynamic indicator 21 is a transflective display screen that is uniformly illuminated by the illumination means 25 in the background.

The escape route sign 13 may further include a memory 27 on which graphics for display on the dynamic indicator 21 are stored in whole or in part.

Escape route sign 13 may also include a local power system, such as local battery 28 or another local power source (super capacitor, fuel cell, etc.), for powering dynamic indicator 21. Furthermore, the escape route sign 13 can also be connected to a central battery system 14 of the escape route indicating system 10.

The escape route sign 13 can interpret a control command of the control unit 15, similar to a scene call, and can display a corresponding graphic. The control command does not generally include the entire graphic but only the address of the corresponding escape route sign 13 and the image ID. This can in particular speed up the communication and avoid transmission errors.

The escape route sign 13 can recognize that it is being controlled by itself through the address. For this purpose, the dedicated electronic device in the escape route sign 13 can read out the address and assign the figure by the image ID. The pattern of image IDs may be stored in memory 27. The electronics correspondingly control the dynamic indicator 21, which then displays a graphic.

In addition, new graphics, for example new pictograms, can be loaded into the memory 27 of the escape route sign 13 by means of the updating function of the battery system 14.

Furthermore, the escape route sign 13 can have a communication interface 29. The communication interface 29 is, for example, an NFC interface, a Digital Addressable Lighting Interface (DALI), or a Power Line Communication (PLC) interface.

The graphics, in particular pictograms, can be transmitted to the memory of the escape route sign 13 via the communication interface 29. If transmitted via NFC, the graphics can be loaded directly onto the memory of the dynamic indicator 13 using a smartphone, tablet or laptop.

Fig. 3a to 3b show schematic views of further embodiments of the escape path sign 13.

The escape route sign 13 can be controlled according to circumstances. In addition to the escape path display, the dynamic indicator 21 may also display other additional information, for example information about a dangerous situation, escape path recommendations, alternative paths, persons in distress, etc. Here, additional information may be provided to people or rescuers within the building. Here, different information or supplementary information may be displayed on the first display area 21a and the second display area 21b of the dynamic indicator 21.

Fig. 3a shows, for example, a safety marking for a fork in a first display area 21a, and additional information in the form of further pictograms and a soiling warning in a lower, second display area 21 b. This can alert people to the danger on the escape route and select an alternative route.

Fig. 3b shows one security symbol in the first display area 21a and three flashing arrows in the second display area 21 b. The perception of the escape route display can be improved by the animation in the second display area 21 b.

Fig. 4 shows a schematic view of a preferred embodiment of the escape path sign 13.

The dynamic indicator 21 is designed as a segment indicator in fig. 4 and comprises a plurality of individual segments 51. The segments are determined by superimposing all displayable pictograms.

The pictograms that can be displayed are, for example, arrow directions in steps of 45 ° and stylized human figures, which can be displayed on the left and right sides of the indicator 21, respectively. By superimposing these patterns, for example about 200 segments 51 are produced which can be controlled individually.

Control of the individual segments 51 may be achieved by etching the back plate. The back plate may comprise dedicated electronics and may be designed for communication with further electronics of the escape path sign 13. In this way, the back plate can be controlled, for example by means of the SPI interface, to illuminate certain segments 51 in order to embody a specific pictogram and/or arrow on the indicator 21.

Fig. 5 shows a schematic illustration of a preferred embodiment of a method 70 for dynamically and/or adaptively displaying an escape path.

The method 70 comprises detecting 71 an escape path-related physical quantity, determining 73 a control signal based on the detected physical quantity, controlling 75 the escape path signs 13a-c with the control signal, and displaying 77 a complete or partially pre-stored graphic on a dynamic indicator 21 of the escape path signs 13a-c, wherein the dynamic indicator 21 is designed to maintain the graphic in a power-off state.

Method 70 of fig. 5 may be implemented using dynamic and/or adaptive escape path indicating system 10, which is schematically illustrated in fig. 1.
