Definitions
- Escape direction display system display device for use therein and method for driving a display device
- the invention relates to an escape direction display system with variable display devices.
- escape direction display system with variable display devices known (DE 196 44 127 AI), in which the display of the escape direction is not carried out by unchangeable signs, but by controllable display devices.
- Such an escape direction display system has the advantage that the respectively indicated escape direction can be adapted to the circumstances and flexibly controlled depending on the hazard. As soon as the source of the fire in the building is known, for example, all escape routes can lead away from this source of fire and enable safe evacuation even in the area around the source of the fire, without designated escape routes leading into the danger zone.
- Such a dynamic escape direction display can be connected directly to suitable hazard detection devices within the building or to an external fire alarm center and thus display the appropriate escape route, regardless of manual specifications.
- the escape route should be displayed as clearly and intuitively as possible, so that a panicked person can recognize the escape direction display and follow it even when there is a lot of smoke.
- all indications of an escape direction and corresponding information should be as inconspicuous as possible during normal building use and should be aware of this Subordinate the desired appearance of the premises.
- Legal For certain buildings, regulations regulate the requirements for a permitted escape direction indicator system, for example the minimum size of the signage. Major fire disasters at airports or in train stations have shown, however, that larger and clearer signage as well as additional measures to indicate escape routes are desirable and can be life-saving in an emergency.
- the object of the invention is therefore to design an escape direction display system of the type mentioned at the outset in such a way that a simple and clearly perceptible escape direction display is made possible in an emergency, while the escape direction displays should be as inconspicuous as possible when the building is used undisturbed.
- the display devices can be switched between the display of an escape direction and the display of any information. Since the display devices • can reproduce any information and are not perceived as part of an escape direction display system during undisturbed use of the building, the individual display devices can be designed sufficiently large, or can be arranged in large numbers with small distances from one another, in order to be able to, in an emergency
- an escape direction display system Indicate escape direction clearly perceptible, but without otherwise being perceived as disturbing.
- the Expenses incurred for the installation and operation of an escape direction display system can be at least partially compensated for by the possibility of other use. It is also conceivable to additionally use individual or all display devices of the escape direction display system as information or advertising areas. For example, in a department store, a display device of the escape direction display system near the entrances or escalators could be used as an orientation plan for the individual department store areas, while other display devices within the respective areas can be used as advertising spaces for certain products. Suitable constructive measures can be taken to ensure that, in an emergency, the display is switched to show an escape direction regardless of the information currently being displayed.
- the display device can also be used as a door sign.
- the display device can also be used as a door sign.
- many people orient themselves only along the walls when there is a lot of smoke, since the smoke often rises to the ceiling and makes it difficult or impossible to recognize the escape direction indicators hanging from the ceiling.
- Display devices also used as door signs are also used as door signs.
- Escape direction indicator systems are usually mounted on the walls at eye level next to the doors. They can be easily noticed there even under unfavorable conditions and can be found quickly due to their regular arrangement. Furthermore, in an emergency, the suitable escape route is immediately when you leave the room is displayed without having to search for the nearest indication of the direction of escape that is irregularly arranged along the aisle. Since at least simple door signs are necessarily provided in many buildings, the combination with one could
- Escape direction display system the costs required compared to the separate design of door signs and escape direction display system can be significantly reduced. So-called intelligent door signs, the display of which can be changed for changing room use, can also be easily adapted to the requirements for use as part of an escape direction display system.
- the display devices are connected to a central control unit.
- This enables a variable display of escape directions adapted to the circumstances instead of the otherwise exclusively possible display of a predetermined, unchangeable escape direction.
- the connection of individual display devices with a central control unit further enables particularly simple change and control of the information displayed outside of emergency situations.
- the escape direction display system has a connection to a fire alarm control panel. This can ensure that the direction-of-escape system depends on the display of the independent of other hazard detectors that may already be impaired in their function Escape direction switches if the fire alarm center has the relevant information.
- the information available to the fire alarm center can also be used to enable intelligent control of the indicated escape directions that is adapted to the intended rescue measures.
- the invention also relates to a display device as part of an escape direction display system, in particular an escape direction display system described above, the display device being switchable between the display of an escape direction and the display of any information.
- the display device has a control unit for switching between the display of any information and the display of an escape direction.
- the control unit can then in
- control unit can in the case of conflicting information, in particular in the
- the control unit has a device for voltage monitoring of the external power supply.
- the energy supply to electrical systems is often impaired, causing them to fail or no longer function properly.
- the control unit can switch the display device directly to indicate the direction of escape.
- the display device expediently has an internal energy supply, for example an adequately dimensioned battery, in order to ensure the display of an escape direction for a sufficient period of time even after the external power supply has completely failed.
- the display device has a single battery system with a charging device and deep discharge protection.
- a charging device and deep discharge protection.
- Such an energy supply that is independent of the outside world complies with current safety regulations and enables the display device to be virtually maintenance-free for years against a failure of the external power supply, whereby it is ensured that, depending on the capacity of the battery arrangement, the display of an escape direction is ensured for at least 60-90 minutes is.
- the display device has an electronic information display element. Bright screens or displays such as LCD or diode displays are expediently used for such a display device.
- variable display devices are also conceivable in which it is largely possible to switch mechanically between different displays.
- the display device has an image storage unit for at least one escape direction display.
- the display device when installing the display device as part of a
- Escape direction display system an escape direction display adapted to the arrangement of the display device can be stored in the image storage unit.
- the stored escape direction display then only has to be loaded and displayed, which can be done in a very short time without the need for information transfer from an external information source to the display device in question.
- the image storage unit can be protected against unauthorized access by suitable measures, so that manipulation of the escape direction display to be displayed in an emergency is largely ruled out.
- the display device has an interface to a computer network.
- a computer network can, for example, enable a dynamic display of the most suitable escape direction adapted to the actual circumstances.
- the ones to be displayed outside of an emergency situation can also be displayed
- the display device has an interface for programming the image storage unit for the escape direction display or for programming the control information.
- the display device can have, for example, a standardized connection socket, which represents the only access to the image storage unit.
- the image storage unit could then not be manipulated via other connections, in particular the connection to a computer network, which is required by some legal regulations.
- the image storage unit could then only be accessed via the programming interface, for example by directly connecting a suitably equipped portable computer or a programming device, which can only be carried out unnoticed in a few cases.
- the invention relates to a method for controlling a display device of an escape direction display system, in particular for controlling one of the display devices described above.
- the method includes the detection of a dangerous situation and the subsequent switching of the display from any display to a given or transmitted escape direction display.
- data transmitted to the display device are monitored for control information for switching the display, so that central control of the individual display devices is made possible. It can make sense that several pieces of information for switching the display are compared and evaluated. Thus, if the external power supply is lost, it could open automatically the escape direction display is switched over, although according to the control information transmitted to the display device, the display of any information should remain.
- Fig. 1 is a display device in the representation of an escape direction display
- Fig. 2 shows the display device shown in Fig. 1 during the display of door plate information.
- Display device 1 has a display unit 2 and a control unit 3.
- the information reproduced in the display unit 2 can be predetermined and changed by the control unit 3.
- the control unit has an image memory for the escape direction display 4 and an image memory unit 5 for any information to be displayed. While the image storage unit 5 is accessible for any information to be displayed via a network connection 6 and can be changed in any way, the image storage unit to the escape direction display 4 has no network connection for security reasons, so that a change in the stored escape route symbol via a network access is excluded.
- the information to be displayed by the display unit 2 is taken either from the image storage unit for the escape direction display 4 or from the image storage unit 5 any information.
- the selection of the information to be displayed is made by a selection unit 7, which in the simplest case can switch between the individual image storage units 4 and 5.
- the selection unit 7 could, however, also choose between a plurality of image storage units as a function of predefined parameters or allow a dynamic adaptation of the information to be displayed.
- the selection unit 7 is connected to a voltage monitoring device 8, which in turn is connected to an external power supply via a supply line 9.
- the external power supply not shown, also serves to supply power to the display device 1 in normal, undisturbed operation
- Voltage monitoring device 8 continuously monitors the voltage provided by the external energy supply. As soon as the monitored voltage of the external energy supply deviates from the target value by more than a predetermined value, the
- Selection unit 7 on the display of the escape direction. In this way it can be ensured that even in the event of a complete failure of the external power supply, an emergency is automatically recognized and the specified escape direction display is shown. In this case, the energy supply of the display device 1 is ensured by a battery arrangement, not shown.
- the selection unit 7 is also connected to an evaluation unit 10, which is also connected to an external computer or network via the network connection 6.
- the evaluation unit 10 can search the data transmitted via the network connection 6 for control commands for the selection unit 7 and, if necessary, pass them on to the selection unit 7. By correspondingly transmitting control commands via the network connection 6, any information and the escape direction display can also be switched between the display.
- an intelligent escape direction display which is adapted to the dangerous situation can also be implemented.
- a plurality of escape direction displays must be stored in the display device 1 or be available via the network connection 6, between which the selection unit 7 can select and switch over depending on the control commands transmitted.
- the image storage unit to the escape direction indicator 4 has no direct network connection 6, but can only be accessed via an interface 11 that is accessible from the outside a suitable device, for example a portable computer, can be changed or overwritten.
- a suitable device for example a portable computer
- basic parameters for example access authorizations or identification information of the display device 1 in the network, can be protected against undesired manipulation via the network connection 6.
- a plurality of display devices 1 can be connected to form a complex escape direction display system.
- each display device 1 is connected via the network connection 6 to a central control unit, via which a situation-dependent, dynamic activation and control of the respectively indicated escape direction can take place.
