Description

Die vorliegende Erfindung bezieht sich auf eine Aufzugsanlage für einen Aufzugsschacht, mit einem darin angeordneten Fahrkorb, einer Aufzugssteuerung, die aus einer Elektronik mit einer Hardware und Software besteht, an die verschiedene Sensoren und Betätigungselemente angeschlossen sind, und einem Steuerungssystem zur Schachtentrauchung mit daran angeschlossenen Rauchmeldern.The present invention relates to a hoistway elevator system having a car therein, an elevator controller consisting of electronics with hardware and software to which various sensors and actuators are connected, and a smoke exhaust control system with smoke detectors connected thereto ,

In Aufzugsanlagen muss für einen Brandfall die Entrauchung sicher gestellt werden. In älteren Aufzugsanlagen waren dazu im Aufzugsschacht Permanentöffnungen vorgesehen, durch die ein im Aufzugsschacht befindlicher Rauch abziehen kann. Da durch die Permanentöffnungen jedoch im Brandfall nicht nur Rauch, sondern wegen der Dauerbelüftung auch mit erheblichem Energieaufwand gekühlte oder beheizte Luft aus einem Gebäude in die Umwelt abgegeben wird, sind die bekannten Permanentöffnungen nicht energieeffizient. Hierauf wird in der Schrift LU 91 175 hingewiesen.In lift systems, the smoke extraction must be ensured in the event of a fire. In older elevator installations, permanent openings were provided in the elevator shaft, through which a smoke located in the elevator shaft can be drawn off. However, since in the event of a fire not only smoke but also cooled or heated air is released from a building into the environment through the permanent openings in the event of fire, the known permanent openings are not energy-efficient. This is indicated in the document LU 91 175.

Um eine höhere Energieeffizienz zu schaffen, sind aus dem Stand der Technik motorisch betreibbare Rauchabzugsklappen bekannt, die an Rauchmelder angeschlossen sind. Ein Beispiel hierfür findet sich in der Schrift DE 20 2006 012 724 U1 . Um mit einem Rauchmelder ausreichend sicher einen Brand erkennen zu können, werden als Rauchmelder Rauchansaugsysteme verwendet, die ständig Luft aus dem Aufzugsschacht ansaugen und auf Rauchbestandteile hin untersuchen.In order to create a higher energy efficiency, motor-operated smoke flaps are known from the prior art, which are connected to smoke detectors. An example of this can be found in the Scriptures DE 20 2006 012 724 U1 , In order to be able to reliably detect a fire with a smoke detector, smoke detectors are used as smoke detectors, which constantly suck in air from the elevator shaft and examine it for smoke components.

Die aktuellen Aufzugsschachtentrauchungssysteme sind außerordentlich aufwendig und verteuern die Anschaffung eines Aufzugs. Es ist die Aufgabe der vorliegenden Erfindung, eine energieeffiziente Rauchüberwachung in einer Aufzugsanlage zu schaffen, bei der der technische Aufwand verringert ist.The current lift shaft smoke extraction systems are extremely expensive and make the purchase of an elevator more expensive. It is the object of the present invention to provide an energy-efficient smoke monitoring in an elevator installation, in which the technical complexity is reduced.

Die Aufgabe wird gelöst, indem das Steuerungssystem zur Schachtentrauchung ein Bestandteil der Aufzugssteuerung ist, wobei die Hardware und Software für die Aufzugssteuerung um die für das Steuerungssystem zur Schachtentrauchung erforderliche Software ergänzt ist.The object is achieved by the control system for shaft smoke extraction is a part of the elevator control, the hardware and software for the elevator control is supplemented by the required for the control system for Schachtentrauchun g software.

Eine elektronische Aufzugssteuerung ist zur Steuerung der Fahrbewegungen des Fahrkorbs im Aufzugsschacht immer vorhanden. Die Aufzugssteuerung besteht aus einer Elektronik, an die verschiedene Sensoren und Betätigungselemente angeschlossen sind. Über eine Software, die in der Steuerung in einem Baustein gespeichert ist, werden die Bedienbefehle und Sensorsignale in Stellbefehle verrechnet, durch die der Antrieb für den Fahrkorb ein- oder ausgeschaltet, beschleunigt oder abgebremst wird, Türen geöffnet oder geschlossen werden, über Lasthinweise ausgegeben werden und dergleichen. Die Aufzugssteuerung ist mit Bedienstationen in verschiedenen Stockwerken verbunden, die mit dem Fahrkorb erreichbar sind. Somit ist für die Aufzugssteuerung auch eine Verkabelung im Aufzugsschacht vorhanden. Darüber hinaus weist die Aufzugsanlage in der Regel im Aufzugsschacht Führungen für den Fahrkorb und/oder das Gegengewicht auf, an denen Rauchmelder positioniert werden können. Die erfindungsgemäße Aufzugsanlage für einen Aufzugsschacht kann diesen allerdings auch zumindest teilweise -beispielsweise bei Außenanlagen- mit ausbilden.An electronic elevator control is always present for controlling the driving movements of the elevator car in the elevator shaft. The elevator control consists of electronics to which various sensors and actuators are connected. Using software stored in the controller in a block, the operating commands and sensor signals are offset in setting commands that switch the drive for the car on or off, accelerate or decelerate, open or close doors, and output via load notes and the same. The elevator control is connected to operating stations on different floors, which can be reached by car. Thus, a wiring in the elevator shaft is available for the elevator control. In addition, the elevator installation generally has guides for the car and / or the counterweight in the elevator shaft, at which smoke detectors can be positioned. The elevator installation according to the invention for an elevator shaft However, this can at least partially, for example, in outdoor facilities with training.

Wegen der bereits für die Aufzugssteuerung vorhandenen Soft- und Hardware, der Verkabelung, der Sensoren und der Bedienelemente, kann darauf verzichtet werden, entsprechende Bauteile noch ein zweites Mal für ein Aufzugsschachtentrauchungssystem zu installieren. Um ein Steuerungssystem zur Schachtentrauchung mit einer vorhandenen Aufzugssteuerung zu kombinieren, genügt es, auf der vorhandenen Hardware für die Aufzugsteuerung die für das Steuerungssystem zur Schachtentrauchung erforderliche Software zu ergänzen. Gegebenenfalls können auch noch für das Steuerungssystem erforderliche Hardwarekomponenten an die Aufzugssteuerung angebaut werden. So ist es möglich, das Steuerungssystem zur Schachtentrauchung als Option auf die Hardware und Software der Aufzugssteuerung aufzusetzen, um die Aufzugssteuerung mit dem Steuerungssystem zur Schachtentrauchung zu kombinieren.Because of the already existing for the elevator control software and hardware, the wiring, the sensors and controls, it can be waived to install appropriate components a second time for a lift shaft smoke removal system. In order to combine a smoke exhaust control system with an existing elevator control, it is sufficient to supplement the software required for the smoke exhaust control system on the existing elevator control hardware. Optionally, even for the control system required hardware components can be attached to the elevator control. Thus, it is possible to set up the smoke exhaust control system as an option on the elevator control hardware and software to combine the elevator control with the smoke exhaust control system.

Die vorstehend beschriebene Aufgabe wird auch gelöst durch eine Aufzugsanlage für einen Aufzugsschacht, mit einem darin angeordneten Fahrkorb, einer Aufzugssteuerung und einem Steuerungssystem zur Schachtentrauchung mit wenigstens einem angeschlossenen Rauchmelder, wobei die Aufzugsanlage sich dadurch auszeichnet, dass sie zumindest zwei Rauchmelder aufweist, von denen einer für den im Aufzugsschacht oberhalb des Fahrkorbs ausbildbaren Bereich und einer für den im Aufzugsschacht unterhalb des Fahrkorbs ausbildbaren Bereich vorgesehen ist. Unabhängig von der Position des Fahrkorbs können die verschiedenen Bereiche im Aufzugsschacht somit optimal überwacht werden. Das Steuerungssystem zur Schachtentrauchung kann sowohl als separate Steuerung als auch als in die Aufzugssteuerung integrierte Steuerung ausgebildet sein. Für die Anordnung der Rauchmelder können neben den vorhandenen Führungen auch geeignete Bereiche der Schachtwand, des Schachtbodens und der Schachtdecke in Frage kommen. Die nachfolgend beschriebenen Ausführungen können sich sowohl auf die Ausgestaltung der Erfindung gemäß Anspruch 1 als auch gemäß einer der Varianten nach Anspruch 4 beziehen.The object described above is also achieved by an elevator installation for an elevator shaft, with a car arranged therein, an elevator control and a control system for shaft smoke extraction with at least one connected smoke detector, wherein the elevator installation is characterized in that it has at least two smoke detectors, one of which is provided for the area which can be formed in the elevator shaft above the car and one for the region which can be formed in the elevator shaft underneath the car. Regardless of the position of the car, the different areas in the Elevator shaft are thus optimally monitored. The smoke exhaust control system can be designed both as a separate control and as an integrated control in the elevator control. For the arrangement of the smoke detector, suitable areas of the shaft wall, the shaft floor and the shaft ceiling can be used in addition to the existing guides. The embodiments described below may relate both to the embodiment of the invention according to claim 1 and according to one of the variants of claim 4.

Nach einer Ausgestaltung der Erfindung ist das Aufzugssteuerungssystem als Bussystem aufgebaut und die das Steuerungssystem zur Schachtentrauchung betreffenden Sensordaten, Stellbefehle und sonstigen Informationen sind vom Bussystem der Aufzugssteuerung übertragbar. Bussysteme sind als elektronische Netzwerke in Maschinen und Anlagen weit verbreitet. Bussysteme funktionieren über ein Datennetzwerk, an das verschiedene Systeme über einen Mikroprozessor angeschlossen sind. Die Mikroprozessoren senden Datenpakete in das Datennetzwerk, die mit einer Adressierung versehen sind, welche Dringlichkeit die übermittelten Daten aufweisen und an wen die im Datenpaket enthaltenen Informationen gerichtet sind. Das Steuerungssystem zur Schachtentrauchung kann an ein Bussystem angeschlossen werden, indem die Steuerung zur Schachtentrauchung ebenfalls über einen Mikroprozessor an das Datennetzwerk angeschlossen wird und auf diese Weise beispielsweise Sensordaten empfangen und Stellbefehle ausgeben kann. An das Bussystem können zudem entfernt von der Steuerung angeordnete Komponenten - wie beispielsweise Rauchmelder, Stellmotoren von Entrauchungsklappen und dergleichen - ebenfalls über einen Mikroprozessor entsprechend angeschlossen werden. Das Erfordernis einer direkten Verkabelung zwischen den entfernter liegenden Komponenten und der Steuerung der Schachtentrauchung entfällt damit. Es versteht sich, dass die Erfindung auch mit einem auf herkömmlicher Verdrahtung basierenden Übertragungssystem realisierbar ist. Auch Mischformen sind möglich.According to one embodiment of the invention, the elevator control system is constructed as a bus system and the sensor system, control commands and other information relating to the control system for shaft smoke extraction can be transmitted by the bus system of the elevator control. Bus systems are widely used as electronic networks in machinery and equipment. Bus systems operate over a data network to which various systems are connected via a microprocessor. The microprocessors send data packets into the data network which are provided with addressing, which urgency the transmitted data have and to whom the information contained in the data packet is directed. The smoke exhaust control system can be connected to a bus system by also connecting the smoke exhaust control unit to the data network via a microprocessor and thus, for example, be able to receive sensor data and output control commands. In addition to the bus system components arranged away from the control - such as smoke detectors, actuators of smoke control dampers and the like - also be connected via a microprocessor accordingly. The requirement of direct wiring between the more distant components and the control of the shaft smoke evacuation is thus eliminated. It is understood that the invention can also be implemented with a conventional wiring based transmission system. Also mixed forms are possible.

Nach einer Ausgestaltung der Erfindung sind die Rauchmelder mit der Aufzugssteuerung verbunden. Dies kann beispielsweise über die vorstehend beschriebene Anbindung der Rauchmelder an ein Bussystem erfolgen, aber auch beispielsweise über eine herkömmliche Verkabelung. Durch den Anschluss der Rauchmelder an die Aufzugssteuerung können die Rauchmelder Sensorsignale an die Aufzugssteuerung übermitteln. Die Aufzugssteuerung leitet die Sensorsignale sodann an das gegebenenfalls als Subsystem ausgebildete Steuerungssystem zur Schachtentrauchung weiter, wo sie ausgewertet werden und von wo aus je nach Ergebnis der Auswertung Stellbefehle an die Aufzugsteuerung oder an sonstige Alarmgeber, Stellmotoren, Verriegelungen und dergleichen weitergeleitet werden.According to one embodiment of the invention, the smoke detectors are connected to the elevator control. This can be done for example via the above-described connection of the smoke detector to a bus system, but also for example via a conventional wiring. By connecting the smoke detector to the elevator control, the smoke detectors can transmit sensor signals to the elevator control. The elevator control then forwards the sensor signals to the smoke removal control system, which may be designed as a subsystem, where they are evaluated and from where, depending on the result of the evaluation, control commands are forwarded to the elevator control or to other alarm transmitters, servomotors, interlocks and the like.

Nach einer Ausgestaltung der Erfindung werden als Rauchmelder ein oder mehrere punktförmige Rauchmelder verwendet. Punktförmige Rauchmelder sind als Standardbauteile kostengünstig verfügbar. Der prinzipbedingte Nachteil, dass diese nur dazu in der Lage sind, im Bereich ihres Anbringungsortes eine Verrauchung zu prüfen, kann überwunden werden, indem mehrere punktförmige Rauchmelder im Aufzugsschacht verteilt angeordnet werden. So ist beispielsweise besonders bevorzugt vorgesehen, einen punktförmigen Rauchmelder an der Unterseite des Fahrkorbs, am Gegengewicht und/oder im Schachtkopf anzubringen. Einem einzigen punktförmigen Rauchmelder, der an einer beliebigen Stelle im Aufzugsschacht angeordnet ist, könnte entgehen, dass sich in einem vom Anbringungsort entfernter liegenden Teil des Aufzugsschachtes Rauch ansammelt. Da der Fahrkorb den darüber und darunter liegenden Teil des Aufzugsschachtes voneinander trennt, ist es vorteilhaft, wenn mindestens ein punktförmiger Rauchmelder jeweils im oberen und unteren Teil des Aufzugsschachtes vorhanden ist. Befinden sich punktförmige Rauchmelder am Fahrkorb und/oder am Gegengewicht, werden die punktförmigen Rauchmelder bei einer Benutzung des Fahrkorbs jeweils durch die Höhe des Aufzugsschachtes bewegt. Befindet sich der Fahrkorb am oberen Ende des Aufzugsschachtes, ist das Gegengewicht am entgegengesetzten Ende, und anders herum. Die Anbringung eines punktförmigen Rauchmelders im Bereich des Schachtkopfes ist sinnvoll, da Rauch durch die bei einem Brand entstehende Wärme häufig nach oben zieht und aus diesem Grund erwarten werden kann, dass sich im Aufzugsschacht befindlicher Rauch insbesondere im Schachtkopf erkennen lässt.According to one embodiment of the invention, one or more punctiform smoke detectors are used as smoke detectors. Pointed smoke detectors are available as standard components at low cost. The inherent disadvantage that they are only able to check a smoke in the region of their mounting location, can be overcome by several point smoke detectors are distributed in the elevator shaft. For example, it is particularly preferred to provide a punctiform smoke detector on the underside of the car, to be attached to the counterweight and / or in the shaft head. A single point smoke detector located anywhere in the elevator shaft could escape the accumulation of smoke in a part of the elevator shaft farther from the mounting location. Since the car separates the above and below part of the elevator shaft from each other, it is advantageous if at least one point-shaped smoke detector is present in each case in the upper and lower part of the elevator shaft. If punctiform smoke detectors are located on the car and / or on the counterweight, the punctiform smoke detectors are each moved by the height of the elevator shaft when the car is being used. If the car is at the top of the elevator shaft, the counterweight is at the opposite end and vice versa. The attachment of a point-shaped smoke detector in the region of the shaft head is useful because smoke often pulls up by the heat generated in a fire and can be expected for this reason that located in the elevator shaft smoke can be seen in particular in the shaft head.

In einer weiteren Ausgestaltung der Erfindung sind am Fahrkorb und/oder am Gegengewicht Rauchableitbleche angebracht, um dadurch einen im Aufzugsschacht befindlichen Rauch auf die Rauchmelder zu leiten. Die Rauchmelder können nach einer Ausgestaltung der Erfindung in der Nähe einer Tür zum Aufzugsschacht angeordnet sein, weil bei einem Brand in einem Geschoss eines Gebäudes der Rauch jeweils durch die Türen in den Aufzugsschacht gelangen wird. Dabei sollte der Rauchmelder so positioniert sein, dass der für das Gegengewicht oder einen Zylinder eines hydraulischen Aufzugs erforderliche Bauraum nicht beeinträchtigt wird. Werden der Fahrkorb und das Gegengewicht im Aufzugsschacht bewegt, kann der Rauch durch die Rauchableitbleche auf die Rauchmelder zugeleitet werden.In a further embodiment of the invention Rauchableitbleche be mounted on the car and / or the counterweight, thereby to guide a located in the elevator shaft smoke on the smoke detector. According to one embodiment of the invention, the smoke detectors may be arranged in the vicinity of a door to the elevator shaft, because in the case of a fire in a projectile of a building, the smoke will in each case pass through the doors into the elevator shaft. The smoke detector should be positioned so that the space required for the counterweight or a cylinder of a hydraulic lift is not impaired. If the car and the counterweight move in the elevator shaft, the smoke can be passed through the Rauchableitbleche on the smoke detectors.

Nach einer weiteren Ausgestaltung der Erfindung ist an die Aufzugssteuerung des Weiteren zumindest ein Temperatursensor angeschlossen. Durch den Temperatursensor kann die aktuelle Temperatur im Aufzugsschacht überwacht werden. Steigt die Temperatur im Aufzugsschacht betriebsbedingt an, beispielsweise durch viele Nutzer, Sonneneinstrahlung, Abwärme vom Antrieb oder dergleichen, kann die Aufzugssteuerung ein Signal an das Steuerungssystem zur Schachtentrauchung und/oder an einen Antrieb zum Öffnen und Schließen einer Rauchschutzklappe ausgeben, durch das die Rauchschutzklappe geöffnet wird, um den Aufzugsschacht zu entlüften und mit Frischluft abzukühlen. Überschreitet der vom Temperatursensor gemessene Wert einen vorprogrammierten Grenzwert, kann ein solcher Grenzwert von der Aufzugssteuerung und/oder dem Steuerungssystem zur Schachtentrauchung auch als Hinweis auf einen Brand gewertet werden, wodurch dann die für einen Brandfall vorgesehenen Schaltabläufe ausgelöst werden. Des Weiteren kann die Aufzugsanlage einen Feuchtigkeits- und/oder einen Windsensor aufweisen, um bei entsprechend klimatischen Bedingungen die Rauchschutzklappe öffnen bzw. schließen zu können.According to a further embodiment of the invention, at least one temperature sensor is connected to the elevator control. The temperature sensor can be used to monitor the current temperature in the hoistway. If the temperature in the elevator shaft increases due to the operation, for example due to many users, solar radiation, waste heat from the drive or the like, the elevator control can output a signal to the control system for shaft smoke extraction and / or to a drive for opening and closing a smoke protection flap, through which the smoke protection flap opens is to bleed the elevator shaft and cool with fresh air. If the value measured by the temperature sensor exceeds a preprogrammed limit value, such a limit value can also be evaluated by the elevator control and / or the smoke exhaust control system as an indication of a fire, whereby the switching processes provided for a fire are triggered. Furthermore, the elevator installation can have a moisture sensor and / or a wind sensor in order to be able to open or close the smoke protection flap in accordance with climatic conditions.

Nach einer Ausgestaltung der Erfindung ist eine motorisch betätigbare Rauchschutzklappe von der Aufzugssteuerung betätigbar. Um von der Aufzugssteuerung betätigt werden zu können, ist die motorisch betätigbare Rauchschutzklappe mit einer Steuerung oder einem Schalter mit der Aufzugssteuerung verbunden. Hat die Aufzugssteuerung selbst oder das Steuerungssystem zur Schachtentrauchung erkannt, dass eine Bedingung zum Öffnen der Rauchschutzklappe vorliegt, so kann die Aufzugssteuerung und/oder das Steuerungssystem zur Schachtentrauchung über die Aufzugssteuerung ein entsprechendes Stellsignal an den Antrieb der Rauchschutzklappe übermitteln, durch die diese entweder geöffnet oder geschlossen wird.According to one embodiment of the invention, a motor-operated smoke damper can be actuated by the elevator control. In order to be actuated by the elevator control, the motor-operated smoke damper is connected to a controller or a switch with the elevator control. Has the Lift control itself or the control system for shaft smoke detected that a condition for opening the smoke damper is present, the elevator control and / or the control system for shaft smoke via the elevator control can transmit a corresponding control signal to the drive of the smoke damper, by which this is either opened or closed ,

Die motorische Betätigung der Rauchschutzklappe kann auf vielfältige Weise realisiert werden. Nach einem Ausführungsbeispiel kann der Motor als ein Federrückstellmotor ausgestaltet sein, d. h., dass der Motor die Klappe gegen eine Feder schließt und dieses elektrisch mit Strom oder mittels einer Verriegelung zuhält. Wird der Motor oder die Verriegelung stromlos, so drückt die Feder die Klappe auf. Nach einer anderen Ausführung ist der Stellmotor als Elektromotor ausgebildet, durch den die Klappe elektrisch geöffnet und geschlossen wird. Diese Variante hat den Vorteil, dass Verklemmungen der Klappe durch Vibrationen oder Rüttelfunktionen des Motors überwunden werden können.The motorized operation of the smoke damper can be realized in many ways. According to one embodiment, the motor may be configured as a spring return motor, i. h., That the motor closes the flap against a spring and this holds electrically with power or by means of a lock. If the motor or the lock is de-energized, the spring pushes the flap. According to another embodiment, the servomotor is designed as an electric motor, by which the flap is opened and closed electrically. This variant has the advantage that jamming of the flap can be overcome by vibrations or vibration functions of the engine.

Nach einer Ausgestaltung der Erfindung ist die Rauchschutzklappe und/oder die Rauchüberwachung im Aufzugsschacht mittels der Aufzugssteuerung abschaltbar. Im Falle der Abschaltung wird für das Schachtentrauchungssystem keine Energie mehr verbraucht. Beispielsweise im Sommer bei höheren Außentemperaturen kann die Rauchschutzklappe in eine dauerhaft offene Position gefahren werden, bevor die Überwachung ausgeschaltet wird. Es kann vorgesehen sein, dass die Aufzugssteuerung die Klappe betätigen kann, wenn bei hohen oder niedrigeren Temperaturen im Schacht eine stärkere oder geringere Kühlung gewünscht wird.According to one embodiment of the invention, the smoke protection flap and / or the smoke monitoring in the elevator shaft can be switched off by means of the elevator control. In the case of shutdown energy is no longer consumed for the shaft smoke extraction system. For example, in summer at higher outside temperatures, the smoke damper can be moved to a permanently open position before the monitoring is switched off. It can be provided that the elevator control can operate the damper when greater or lesser cooling is desired at high or lower temperatures in the duct.

Nach einer Ausgestaltung der Erfindung ist die Rauchschutzklappe mit einer Öffnungsvorrichtung versehen, durch die die Klappe in einem definierten Störungsfall in eine geöffnete Stellung verbringbar ist. Dies kann beispielsweise über eine Notstromversorgung erfolgen, die eventuell schon für den Antrieb des Fahrkorbs vorhanden ist. Auf eine Extra-Notstromversorgung kann für die Schachtentrauchung dann verzichtet werden, da die Notstromversorgung des Aufzugs ausreichend Leistung zur Verfügung stellt, um die Rauchschutzklappe noch zu öffnen. Es kann vorgesehen sein, dass bei einer Abschaltung des Aufzugs oder in einem Standby-Betrieb die Rauchschutzklappe immer in einem geschlossenen Zustand gehalten wird, um ungewollte Wärmeverluste aus dem Schacht zu vermeiden. Dabei können alle übrigen Funktionen wie Rauchmelder, Temperaturüberwachung und Klappensteuerung erhalten bleiben.According to one embodiment of the invention, the smoke protection flap is provided with an opening device, through which the flap can be brought into an open position in a defined fault. This can be done for example via an emergency power supply, which may already be available for driving the car. For an extra emergency power supply can then be dispensed with the shaft smoke, since the emergency power supply of the elevator provides sufficient power to open the smoke damper yet. It can be provided that when the lift is switched off or in a standby mode, the smoke protection flap is always kept in a closed state in order to avoid unwanted heat losses from the shaft. All other functions such as smoke detector, temperature monitoring and damper control can be retained.

Die vorstehend vorgeschlagenen jeweiligen Ausgestaltungen der Erfindung können auf beliebige Weise einzeln oder mehrfach miteinander kombiniert werden und gelten insbesondere für die Ausbildungen der Erfindung gemäß Anspruch 1 sowie die Ausbildungen gemäß einer der Varianten gemäß Anspruch 4.The above-proposed respective embodiments of the invention can be combined individually or multiply in any manner and apply in particular to the embodiments of the invention according to claim 1 and the embodiments according to one of the variants according to claim 4.

Weitere vorteilhafte Ausgestaltungen der Erfindung lassen sich der nachfolgenden gegenständlichen Beschreibung, der Zeichnung und den Merkmalen der Unteransprüche entnehmen.Further advantageous embodiments of the invention can be taken from the following objective description, the drawings and the features of the dependent claims.

Die Erfindung soll nachfolgend anhand eines Ausführungsbeispiels näher beschrieben werden.The invention will be described below with reference to an embodiment.

In der beigefügten Figur ist eine Aufzugsanlage 2 schematisch dargestellt, die einen Aufzugsschacht 4 und einen Fahrkorb 6 aufweist, der im Aufzugsschacht 4 auf und ab beweglich ist. Der Fahrkorb 6 ist im Ausführungsbeispiel mit einem Gegengewicht 8 verbunden. Die Bewegungen des Fahrkorbs 6 werden von einer Aufzugssteuerung 10 gesteuert. Die Aufzugssteuerung 10 ist über Bedienfelder 12 ansteuerbar, die sich in den einzelnen Etagen eines Gebäudes befinden, aber auch im Fahrkorb 6. Die Bedienfelder 12 sind über ein in diesem Ausführungsbeispiel als Busleitung 14 ausgebildetes Übertragungssystem mit der Aufzugssteuerung 10 verbunden.In the attached figure, an elevator system 2 is shown schematically, which has an elevator shaft 4 and a car 6, which is movable up and down in the elevator shaft 4. The car 6 is connected in the embodiment with a counterweight 8. The movements of the car 6 are controlled by an elevator control 10. The elevator control 10 is controllable via control panels 12, which are located in the individual floors of a building, but also in the car 6. The control panels 12 are connected via a trained in this embodiment as a bus line 14 transmission system with the elevator control 10.

An die Aufzugssteuerung 10 angeschlossen ist das Steuerungssystem 16 zur Schachtentrauchung. An die Busleitung 14 angeschlossen sind Rauchmelder 18, ein Temperatursensor 20, ein Stellmotor 22 zur Betätigung der Rauchschutzklappe 24, die alle über die Busleitung 14 Informationen und Daten austauschen können. Die Installation, die für die Aufzugssteuerung 10 und die Bedienfelder 12 in einer herkömmlichen Aufzugsanlage 2 bereits vorhanden ist, kann erfindungsgemäß also auf einfache Weise um die Komponenten ergänzt werden, die für eine Rauchüberwachung und für eine Rauchabzugsanlage erforderlich sind.Connected to the elevator control 10 is the control system 16 for shaft smoke extraction. Connected to the bus line 14 are smoke detector 18, a temperature sensor 20, a servomotor 22 for actuating the smoke damper 24, all of which can exchange information and data via the bus line 14. The installation, which is already present for the elevator control 10 and the control panels 12 in a conventional elevator installation 2, can thus be supplemented according to the invention in a simple manner by the components which are required for smoke monitoring and for a smoke extraction installation.

Der Stromverbrauch des Gesamtsystems kann deutlich verringert werden. Durch die Integration der Rauchüberwachung in die Aufzugssteuerung können Kosten als auch Platz eingespart werden, indem für beide Systeme erforderliche Komponenten nur einmal vorgehalten werden. So kann in der gesamten Aufzugsanlage 2 nur ein einziger Schaltschrank, nur eine Notstromversorgung und nur ein Temperaturfühler vorgehalten werden, obwohl diese Komponenten sowohl für die Aufzugssteuerung 10 wie auch für das Steuerungssystem 16 zur Schachtentrauchung benötigt werden. Auch Wartungs- und Kontrollaufgaben vom Aufzugsmonteur können vereinfacht werden, wodurch die Betriebskosten für die Aufzugsanlage 2 sinken.The power consumption of the entire system can be significantly reduced. By integrating the smoke monitoring in the elevator control costs and space can be saved by components required for both systems are kept only once. Thus, only a single switchgear cabinet, only one emergency power supply and only one temperature sensor can be provided in the entire elevator installation 2, although these components are required both for the elevator control 10 and for the control system 16 for duct smoke extraction. Also, maintenance and control tasks of the elevator fitter can be simplified, whereby the operating costs for the elevator installation 2 decrease.
