Description

The invention relates to a device for fixed installation in a building with at least one wing element and a method for operating the device, wherein the device relates in particular to a door system or a room partition, and the wing element is automatically movable in a movement space, the device monitoring means for monitoring the movement of the Has wing element in order to avoid a collision of the wing element with a person and / or an object.

STATE OF THE ART

Devices for fixed installation in a building usually relate to door systems such as swing doors, sliding doors or revolving doors, or room partitions are known which have wing elements that can be moved with an electric drive. All devices of the type of interest here are permanently installed in the building, and for the electrical operation of the devices, i.e. in particular for moving the wing elements, for example between an open position and a closed position, must be monitored with safety devices, since electrification of the movement of wing elements is usually associated with dangers , and it must be avoided that the moving wing element collides with an object or with a person. For this purpose, monitoring means are known that are installed redundantly in various designs, and cameras can be provided which, for example, stop the movement of a wing element by means of image evaluation when an object or person is present in the movement space or enters it.

In order to achieve the highest possible security of such devices, redundant sensor systems are state of the art, but in addition to the installation of cameras that recognize the need to open a wing element via image evaluation, tactile sensors or other proximity sensors are regularly used, for example optically work with a light barrier or are capacitive or inductive.

For example, the WO 2012/052750 A1 a device for fixed installation with movable leaf elements, and the device is designed as a door system with sliding leaves. The device has cameras as monitoring means in order to recognize the opening requirement of the wing elements. However, infrared sensors and / or radar sensors are also provided in order to monitor the area of the movement space of the wing elements and, if necessary, to stop the movement of the same if there is a threat of a collision with an object or with a person or, in particular with tactile sensors, has already taken place.

The drives and associated control units of such devices are designed so that in the event of a collision of the moving wing element with an object or a person, the wing element is also switched off and, if necessary, reversed in motion in order to create the highest possible degree of safety.

A further example of image recognition for the automatic movement of wing elements of a facility installed fixedly in a building is disclosed in US Pat EP 0 696 670 B1 . Here, too, it is a matter of recognizing the opening requirement through a movement profile of a person, so that wing elements of the facility can be opened and the person can pass the facility, i.e. the door system, for example. Cameras provided for this purpose can also form monitoring means, and if a camera with an associated image evaluation unit detects a person in the movement space of the wing element, then the wing element is not moved further, for example, if a collision with the person can occur.

All devices known from the prior art for fixed installation in a building provide additional safety devices to safeguard against collisions with the moving wing element, which must be installed in a complex manner and monitored in a complex manner via a control unit. In addition to the use of cameras with associated image evaluation units, the data from sensors, tactile sensors, proximity sensors such as capacitive or inductive sensors and the like must be evaluated so that the monitoring means of such a device cause high costs and, in connection with the control unit, involve a high level of control effort. For example, when revolving doors are used, the door revolving door almost always stops, since tactile sensors, optical sensors or sensors that act in some other way detect situations that are categorized as dangerous situations even though there is no actual danger. The monitoring of a motor current of an electric drive for moving the wing element is often used to stop the electric drive or even to reverse it when a limit current is exceeded, so that the wing element executes a reverse movement.

Consequently, monitoring means are known from the prior art for the monitoring of facilities for fixed installation with at least one wing element carried out expensive and cause high costs.

DISCLOSURE OF THE INVENTION

The object of the invention is to develop a device for fixed installation in a building with at least one movable wing element and a method for operating such a device, wherein the device should have monitoring means that are as simple as possible in order to nevertheless provide a high degree of security, in particular to avoid a collision of the to avoid automatically moving wing element with a person and / or with an object.

This object is achieved on the basis of a device according to the preamble of claim 1 and on the basis of a method for operating such a device according to claim 8 with the respective characterizing features. Advantageous further developments of the invention are given in the dependent claims.

The invention includes the technical teaching that all monitoring means are formed from at least one or more cameras and at least one or more image evaluation units, the camera being set up to monitor the movement area.

The core idea of the invention is the complete, without exception, alignment of the monitoring means to the use of at least one or preferably several cameras and at least one or preferably several image evaluation units. This simplifies the implementation of the monitoring means as a whole, since according to the invention the monitoring means are designed free of further sensors. In particular, the monitoring means are free from tactile sensors, free from contactlessly acting proximity sensors, free from capacitively acting proximity sensors and / or free from inductively acting proximity sensors. According to the invention, the monitoring means should be based on cameras, and with image evaluation units it can be recognized whether a person and / or an object is located in the movement space of the at least one wing element, and the control in particular of the drive for moving the wing element stops based on the evaluation of the camera image by means of the image evaluation unit or continues the movement.

With a corresponding evaluation quality and in particular the redundant use of cameras, the movement of the wing element in or through the movement area can be controlled with a very high level of security, and the wing element or components of the facility that are fixed to the building no longer have to be additionally equipped with non-contact or tactile sensors . According to the prior art, cameras are used to control a movement of a wing element of a device for fixed installation in a building in order to set the movement of the wing element in motion, but exclusive use of the data of an image evaluation unit has not been provided so far.

As a rule, camera images are evaluated in order to recognize a movement pattern of a person and in order to use this movement pattern to control a wing element, for example to open a door wing or to move a carousel of a revolving door. Known systems with a camera control and an image evaluation, with which, for example, the drive of the wing element is activated, is always associated in the prior art with the query of further sensors as to whether the movement is actually allowed to start, since it must be checked whether there are objects or people in the Movement space of the wing element are located.

The device according to the invention is based on controlling all monitoring of the movement of the wing element in or through the movement space with monitoring means based exclusively on one or preferably several cameras and on one or preferably several image evaluation units. With today's technology, camera images can be evaluated with such a high quality that, in particular with a redundant arrangement of monitoring means, i.e. at least two cameras, the electrified, in particular automated, operation of the device with motor-driven wing elements can be carried out safely, in particular to avoid collisions with objects and especially with people to avoid.

The image evaluation with the image evaluation unit can take place both before the start of the movement of the wing element in or through the movement space, but in particular there is a real-time evaluation of the camera image with the image evaluation unit in order to also determine the behavior of a person while passing the facility or the stay of a person To monitor person in or adjacent to the movement space of the wing element of the device and, if necessary, to trigger a signal immediately in order to stop or reverse the movement, for example. The evaluation of the camera image with the image evaluation unit thus takes on the function of contactless or tactile proximity sensors, the at least one or preferably the several cameras are attached in connection with the device in such a way that the movement space and in particular also adjacent areas of the movement space are monitored.

With the design of the monitoring means according to the invention, a complex control unit with a large number of sensor inputs is no longer necessary, since the or each of the image evaluation units can adequately provide a signal that is sufficient to stop or reverse the movement of the wing element. The monitoring means and thus the entire facility for fixed installation simplify and become considerably cheaper as a result.

An electric drive is provided for the automatic movement of the wing element into or within the movement space, and a control unit operatively connected to the electric drive is set up, the control unit being operatively connected to the at least one image evaluation unit. In the simplest case, the image evaluation unit transmits a release signal to the control unit if there is no object and / or no person in the movement space of the wing element, so that the movement of the wing element can begin or the movement of the wing element is continued. Furthermore, the image evaluation unit can transmit a stop signal to the control unit when an object or a person is present in the movement space or enters it, with the image evaluation unit also outputting a stop signal to the control unit if a person is at a minimum distance, for example while passing a revolving door falls below a wing element or if a person, in particular also with his limbs or for example with a pet, gets into a danger area of the device, which can be recognized with the image evaluation unit via the at least one camera. A stop signal is then transmitted to the control unit, so that the rotary movement of the wing carousel of the revolving door is stopped without the use of further sensory devices.

The reaction of the control unit and thus the effect on the wing element can also be carried out in several stages or with transitions. For example, the movement of the wing element can be slowed down when an object, and in particular a person, approaches the moving wing element, and the movement only stops completely after the movement has fallen below a minimum safety distance. The monitoring can thus be carried out with a two-stage reaction to the wing element.

According to an alternative, there is the possibility of arranging the at least one camera individually in the vicinity of the device or the at least one camera is arranged on a component of the device that is fixed to the building. As an alternative or in addition, there is of course the possibility of arranging at least one camera on the movable wing element itself. In the case of revolving doors in particular, the close-up area must be monitored, especially in the area of the outer edges, so that it is expedient to also arrange at least one camera directly on the movable wing element, so that the camera is moved with the movement of the wing element. In the case of swing doors or sliding doors, the camera can also be arranged on the wing element itself and consequently also moved with the movement. Wireless data transmission devices can be used for data transmission, in particular between the camera and the image evaluation unit, the latter also being able to be arranged centrally in or on the device. The image evaluation unit is preferably integrated in the camera or designed as a structural unit with it, so that in the simplest case the transmitted data include a hold or release signal that is received by a control unit, for example, which is arranged at rest from the unit comprising the camera and image evaluation unit.

It is further advantageous if at least one first monitoring means are arranged at the beginning and at least one second monitoring means at the end of a movement path of the wing element. The sensor areas of the two cameras can overlap in their monitoring areas so that no part of the movement area remains uncontrolled.

The invention is also directed to a method for operating a building-fixed installed device with at least one wing element, in particular a door system or a room partition, which is automatically moved when the device is operated in a movement space, whereby to monitor the movement of the wing element in order to avoid a collision of the Wing element can be set up and operated with a person and / or with an object monitoring means. The method provides for the following steps: providing the monitoring means by means of one or more cameras for monitoring the movement space without further sensors for monitoring the movement space, generating at least one camera image of the movement space with the camera, providing at least one or more image evaluation units with which the camera image of the movement space is evaluated and release, continuation or interruption of the movement of the wing element based on the evaluated camera image.

According to an advantageous embodiment of the method, the wing element is driven by an electric drive, a control unit operatively connected to the drive being set up, and the control unit requesting a signal from the at least one image evaluation unit to enable, continue or interrupt the movement of the wing element. The interrogation of the signal by the control unit can take place periodically, in particular with a high interrogation frequency, in order to stop the wing element with as little delay as possible after the detection of an object or a person in the movement area.

In particular, the movement of the wing element is monitored over part of or over the entire movement path exclusively via at least one camera, in particular several cameras, and at least one image evaluation unit assigned to the camera, in particular several image evaluation units, is used for image evaluation and the provision of a stop signal.

The control unit can have several signal inputs, each of which is connected to an image evaluation unit, and, for example, the motor drive of the wing element can then be released when a release signal is present on all inputs of the control unit, and each of the release signals is assigned to an evaluation of a camera image Image evaluation unit is based.

The method also provides that, before the device is put into operation, at least one image, a sequence of images or a film of the free, undisturbed movement space is read into the image evaluation unit via the movement path. The interference-free image or the interference-free film can thus be stored as a reference, so that a target / actual comparison can be made with the current image or the current film during the actual operation of the device. If the images or films deviate from one another, there is an object in the movement space and a corresponding stop signal can be derived from this deviation and provided.

The detector zones that can be recorded with the cameras can then be taught-in before the device is put into operation. After an object has been recognized in the movement space and after it has been removed, the control unit can be set up in such a way that the movement of the wing element is resumed or accelerated again.

The at least one camera is arranged for monitoring the movement space on an upper section of a component fixed to the housing or of the wing element, which is remote from a floor. In particular, effective monitoring of the movement space over the substantially entire height of the wing element is carried out when the wing element executes the movement within the movement space.

With an even further advantage, alarm zones can be set up, which are set with regard to their spatial extent before the facility is put into operation.

The device is designed in particular to carry out the method according to the invention, in particular a method according to one of claims 8 to 15. The method can be carried out in particular by means of the device according to the invention, in particular a device according to one of Claims 1 to 7.

The 1 , 2 and 3 show various examples of a facility 100 for installation fixed to the building with at least one wing element each 1 how this can be carried out according to the invention.

1 shows the facility 100 using the example of a door system 11 with linearly movable wing elements 1 , and the wing elements 1 can be opened and closed via an electric drive, as indicated by the double arrows. This creates a space for movement 10 , within which the wing elements 1 can be moved.

The establishment 100 has building components 20th open, and the door system 11 can for example be installed in a passage in a wall of a building or the like.

As part of the facility 100 are exemplary four monitoring means 14th shown as cameras 15th are trained. The cameras 15th are exemplary on the building component 20th arranged, these can alternatively also on the movable wing elements 1 be arranged and the cameras 15th are then with the movement of the wing element 1 moved along.

The cameras 15th are shown by way of example with near-field areas and far-field areas that have a wider angle and a narrower angle. The near-field areas have a large opening angle and the far-field areas have the small opening angle, the far-field areas and the near-field areas being the cameras 15th form assigned detector zones.

With the view it becomes clear that the cameras 15th especially the space for movement 10 so completely cover and monitor that objects or people are in the movement area 10 are present or get into them, immediately from one or more cameras 15th is recognized, then the automatic movement of the wing element 1 to stop.

2 shows the facility 100 using the example of a door system 12th , which is designed as a revolving door. The revolving door has four wing elements, for example 1 on, which can rotate about a common axis of rotation, with the relative position of the wing elements 1 each other does not change. The example initially shows four monitoring means 14th that act as cameras 15th are formed and in free positions the area in and in front of the rotatable carousel with the wing elements 1 cover, especially with the far field range of the cameras. Detect the cameras 15th the entry of a person into the movement area 10 , the collision monitoring can be done with an additional camera 15th in arrangement on the wing element 1 and the other camera 15th forms another component of the monitoring equipment 14th .

For example, the carousel with the wing elements 1 the rotational movement start when the cameras 15th Detect the approach of a person in the free positions around the carousel, which shows the intention to open the door system, in particular on the basis of the person's movement profile 12th to pass, and the collision monitoring of the wing elements 1 with the person is taken over by the cameras 15th in arrangement on the wing elements 1 . The cameras 15th can on the wing elements 1 in the upper area and the cameras 15th then monitor in particular the foot area of the wing elements 1 and the area around the outer edge of the wing elements 1 .

3 shows a facility 100 using the example of a room partition 13th , and there are several wing elements 1 shown, which is either between the two building components 20th can be arranged to form a building partition wall or the wing elements 1 can be in the retracted position adjacent to a building component 20th from the movement space 10 be moved out. The movement of the wing elements 1 takes place, for example, with an electric drive, especially if they are large and have a corresponding mass.

The embodiment shows monitoring means 14th in the form of cameras 15th that are attached to the structural components 20th are arranged and the movement space 10 monitor in such a way that objects and people are detected who are in the movement space of the wing elements 1 are located.

4th shows a schematic structure of the device 100 particularly for carrying out the method of the invention. The establishment 100 has a control unit 18th on that via an electric drive 17th a wing element 1 can move. A single wing element is only an example 1 shown moving from a first position to a second position, thereby increasing the range of motion 10 is formed. The cameras 15th constitute means of surveillance 14th which is also part of the facility 100 are, furthermore is the image evaluation unit shown 16 Part of the facility 100 .

Is the procedure for operating the fixed installation facility 100 with the at least one wing element 1 operated, so is the movement space 10 with the cameras 15th monitored, for example when the wing element 1 through the movement space 10 moved through from the illustrated left side to the imaginary right side. The movement of the wing element 1 takes place, for example, by an electric drive 17th that is controlled by the control unit 18th is controlled.

The activation signal 19th is a signal sent to the control unit 18th acts and, for example, the activation signal 19th manually triggered, for example to open or close a room partition wall at the push of a button, or the activation signal 19th is triggered by optical detection means when the facility 100 for example as a door system 11 or 12th is designed, for example as an automatic door or a revolving door.

At the same time or in a preset state, the cameras are 15th operated to the movement space 10 to be monitored, the monitoring taking place with the image evaluation unit 16 . The example shows an image evaluation unit 16 with both cameras 15th are connected, and the image evaluation unit 16 sends an evaluation signal to the control unit 18th further, the signal from the image evaluation unit 16 to the control unit 18th a release, continuation or interruption of the movement of the wing element 1 based on the evaluated camera image. The image evaluation unit 16 can also be part of the cameras 15th and a signal from these directly to the control unit 18th hand off.

Of course there is also the possibility that the cameras 15th with the image evaluation units 16 are designed as a unit, and there are cameras 15th commercially available that already have an image evaluation unit 16 with associated software. The camera image, which the free movement space 10 shows is in the image evaluation unit 16 previously read in, and will be with the camera 15th an image is recorded that is from the previously read image of the free movement space 10 deviates, the image evaluation unit gives 16 the interrupt signal to the control unit 18th so that the movement of the wing element 1 immediately stops or at least slows down, in particular by switching off or slowing down the electric drive 17th , There is also a reversal of the direction of movement of the wing element 1 through the movement space 10 possible.

The embodiment of the invention is not restricted to the preferred exemplary embodiment specified above. Rather, a number of variants are conceivable which make use of the solution shown even in the case of fundamentally different designs. All of the features and / or advantages arising from the claims, the description or the drawings, including structural details or spatial arrangements, can be essential to the invention both individually and in a wide variety of combinations.
