Description

The present invention relates to a door or door system, in particular for use in an escape and / or rescue route, with a door leaf, in particular rotating or sliding leaf, a person detection device for detecting people in the vicinity of the door leaf and a computer unit that is used to receive a Detection state of the person detection device is connected to this. The invention also relates to a method for operating such a door or door system.

Such doors or door systems are known as such. A person detection device is designed, for example, as a movement sensor, the door leaf typically being able to be driven to open and / or close automatically as a function of the sensor data of the movement sensor.

It is an object of the invention to improve the safety of people who are in or near a building which is equipped with a door or door system of the type mentioned at the beginning.

This object is achieved by a door or door system according to claim 1, and in particular in that at least one normal detection state and / or at least one abnormal detection state is defined in the computer unit, in which the detection state corresponds to a normal or abnormal person situation in the vicinity of the door leaf, and that the computer unit is set up to determine an alarm state if the detection state deviates from the normal detection state or corresponds to the abnormal detection state.

The detection status detected by the person detection device is therefore compared in the computer unit with the normal detection status (s) and / or the abnormal detection status (s). From this it can be deduced whether the personal situation in the vicinity of the door leaf is normal or abnormal. If the personal situation is abnormal, the alarm condition is determined. A normal personal situation can exist, for example, when people move at a normal speed, whereas it can be rated as abnormal when one or more people move faster than usual.

In general, the invention is based on the idea that an alarm condition can be deduced from an abnormal personal situation. For example, if people are moving faster than usual, this can be a sign that there is a hazardous situation and that the people are on the run. However, the alarm state does not necessarily have to relate to a dangerous situation in the sense of a mortal danger. For example, a shoplifter or other intruder can move through the door at high speed, namely flee. In this situation, too, an alarm state can be determined and, for example, the notification of security forces, such as the police, can be used as a basis. In general, an alarm situation is therefore concluded, in particular from the type of movement.

According to the invention, the alarm state is deduced from an abnormal detection state or an abnormal personal situation at the door leaf. On the one hand, this is a particularly simple way of recognizing a dangerous situation. On the other hand, the people are detected by the person detection device exactly where they typically walk when a dangerous situation, for example a fire, is present, namely at a door. In particular, an escape and / or rescue route door or door system is typically arranged in the signposted escape or rescue route and is particularly likely to be passed by people in the event of danger. As a result, the invention makes it possible to reliably identify the alarm state or a dangerous situation with particularly simple means.

In general, the detection status determined by the person detection device can include one or more data that characterize the personal situation in the vicinity of the door leaf, for example number of people, speed, acceleration, direction of movement and / or the like. A normal detection state and / or an abnormal detection state can in principle comprise one or more criteria for application to one or more data of the detection state. The criteria can in particular be stored in the form of intervals and / or threshold values.

For example, a normal detection state can include a criterion according to which a normal, absolute speed of a person is between 0 and 6 km / h. If, for example, the speed of at least one person is outside this interval, in particular greater than 6 km / h, an abnormal personal situation is concluded and an alarm condition is triggered. Alternatively or additionally, for example, an abnormal detection state can include a criterion according to which an absolute speed of a person greater than 6 km / h is abnormal. This can also be used to reliably infer an abnormal personal situation, so that the alarm status is triggered can. Of course, other units of measurement can also be used, depending on the form in which the data on the detection status are provided by the person detection device.

In principle, several different detection states or personal situations can be normal and / or abnormal. Normal can be, for example: “no people detected”, “normal number of people with normal speed of movement” etc. In general, several normal detection states and / or abnormal detection states can also be defined in the computer unit.

The computer unit therefore checks the detection state, in particular by means of at least one criterion, for a deviation from the normal detection state or states and / or for correspondence with the abnormal detection state or states. As a criterion, for example, at least one of the number of people, speed, acceleration, direction of movement and / or frequency of successive detection signals or time between detection signals can be defined, in particular in the form of a threshold value and / or an interval. If there is no normal detection state or at least one abnormal detection state, the presence of an alarm state is determined.

In principle, several or all of these data can be recorded by several person recording devices or by one and the same person recording device. The number of people can be determined, for example, via an image recognition system, as can the direction of movement. It goes without saying that the person detection device can detect one or more of these data and also other data. Accordingly, it is then particularly sufficient that the criteria of the normal detection state or abnormal detection state only relate to the data that are detected by the at least one person detection device.

Furthermore, in principle, one or more people can be detected at the same time, for example by one or more person detection devices. In particular, individual movement properties can be recorded individually, in particular a speed and / or acceleration for each person.

In general, the computer unit can be set up to determine the alarm status when at least one of several criteria is met or when several or all of the criteria are met. For example, different criteria can also be given a different weight. Furthermore, for example, at least one criterion can be defined as sufficient to trigger an alarm state. Alternatively or additionally, a criterion can be defined as a necessary condition, for example. It can also be defined, for example, that the fulfillment of a criterion leads to an alarm state if at least one other criterion is fulfilled.

The data of the detection state, in particular speed and / or acceleration, can generally relate, for example, to a component of the direction of movement of a person, that is to say, for example, a movement component directed towards the door and / or a movement component passing through the door. However, the data can also relate, for example, to an actual direction of movement and / or a direction of movement in three-dimensional space. Alternatively or additionally, an absolute speed of a person can be determined.

According to one embodiment it is provided that the computer unit is set up to determine an alarm state if the detection state with at least one date or several data deviates from the normal detection state or corresponds to the abnormal detection state, in particular if the date or the data is above or below a threshold value lie.

The computer unit can in particular be set up to output an alarm signal when an alarm state is determined. The alarm signal can include, for example, an acoustic, an optical and / or an electrical signal. For example, the alarm signal can be output directly at the door or door system, for example by an alarm transmitter such as a siren and / or a warning light. Alternatively or additionally, an alarm signal, in particular an electrical one, can be communicated to a higher-level point.

In general, it can preferably be provided that the person detection device is arranged at and / or above the door leaf. If the door or door system is an escape and / or rescue route door or door system, an escape situation will, for example, take place in the area of your door leaf and can thus be reliably detected.

According to a further development, it is provided that the person detection device is set up to detect the movement of several people and that the computer unit is set up to detect an alarm state if the movement of at least one person or of at least two or more people in each case corresponds to the specified criterion. The respective criterion can be the same: For example, it is checked for both people whether their speed is within a normal interval. In particular, however, both movements are checked for compliance with at least one criterion.

The computer unit can preferably be set up to determine an alarm state from a set of at least two different alarm states as a function of the detection state. In particular, this can take place as a function of the type of deviation of the detection state from the normal detection state and / or on which abnormal detection state the detection state corresponds to. For example, in the case of many fleeing people, it can be concluded that there is a danger to life and limb, which can include, for example, a fire, an explosion, panic, an amok attack or the like. If, on the other hand, only a fleeing person is recognized, it may be a criminal person, e.g. a shoplifter or the like. These different situations can therefore lead in particular to different, specific alarm states. A differentiation between the alarm states can be improved, for example, by further available information, for example by comparing it with other sensor data of a building system. In particular, different alarm signals can be output for the different alarm states. The different alarm states or alarm signals enable in particular an automatic alerting of those emergency services who are available for the situation in question, i.e. in particular the fire brigade and / or rescue workers in a dangerous situation for life and limb and the police for such a situation in which one or more alleged criminals People are recognized. In particular, the computer unit and / or a higher-level point can be set up to alert emergency services as a function of the alarm status present. In principle, different alarm states can be determined, for example, depending on which criteria are met and / or not met. For example, special criteria can also be defined for different alarm states.

In general, the alarm status can be determined either at the door or centrally at a higher-level point, for example. If the alarm state is detected at the door, an alarm signal can in particular be sent to a higher-level point. If, on the other hand, the alarm status is established at a higher-level point, the detection status or individual data, e.g. speed, acceleration, number of people, etc., can be communicated to the higher-level point. In principle, an alarm state can also be determined in the door, in particular in a door control, and this can be verified at a higher-level point, for example by comparing it with various sensor data or with information from other doors.

In this sense, the computer unit can in particular be arranged on the door. In particular, it can be provided that the computer unit is integrated with the person detection device in a sensor unit, that the computer unit is part of a door control and / or that the computer unit is or can be connected to a superordinate point and, in particular, is set up to send an alarm signal to the superordinate point to spend.

It can also be provided that the computer unit is part of a superordinate point. In this case, in particular, the detection status and / or individual or several of the data from the person detection device are sent to the higher-level point or the computer unit, for example via a bus system. The alarm status is thus determined centrally and can consequently be compared, particularly advantageously, with other data available at the higher-level unit, for example from other doors and / or a building control system, in order to verify them.

It goes without saying that the person detection device, the door control and / or the higher-level unit, independently of the computer unit named here, which determines the alarm status, can have a computing device which, for the purpose of differentiation, should not be referred to as a computer unit, but in principle with regard to the Hardware can be constructed similarly.

In general, the connection between the person detection device and the computer unit can be established, for example, via an interface and / or a BUS. For example, either an alarm signal and / or the detection status or the data of the person detection device can be transmitted via this. In principle, the detection status and data can also be transmitted to a higher-level point if the alarm status is also transmitted to the higher-level point, for example because it is detected at the door.

A higher-level point can be and / or comprise, for example, a building management system, a security system, artificial intelligence and / or security personnel.

The person detection device can in particular have a movement sensor for determining the movement of people in the vicinity of the door leaf, for example a radar, infrared, laser, LiDAR, ToF and / or ultrasonic sensor. "ToF" is an abbreviation for sensors based on the "time-of-flight" principle. In particular, the person detection device can be or comprise a video camera, for example.

In some embodiments it is provided that the door leaf is driven for automatic opening and closing.

It can particularly preferably be provided that the door or door system, in particular escape and / or rescue route door or door system, comprises a door control and a motion sensor, depending on the signals of which the door control opens and / or closes the door leaf. The person detection device can in particular be formed by the same motion sensor. In this way, in particular, the information that the motion sensor captures anyway or can capture with purely software-technical adaptation can be used for the detection of the alarm state. Additional sensors can thus be dispensed with and the security improved according to the invention can be achieved without additional hardware and with only low additional costs.

The computer unit and / or a superordinate point can be set up, for example, to initiate a measure when an alarm state is determined. A measure can include, for example, that all escape doors or other doors in a building are opened. This ensures, for example, that escape routes can be passed even faster. A measure can, for example, also include alerting emergency services, for example the police and / or rescue services.

In particular, the operator of the building which is equipped with the door or door system according to the invention can be given the possibility of reacting to dangerous situations in a simplified manner. In the event of an escape, the door and other doors that are not escape or rescue route doors, for example, can be opened automatically via a building management system so that the escape route is shortened. In the event of a rampage, for example, the attacker can be guided by locking doors. An artificial intelligence can, for example, deduce the position of the danger from a person's escape direction. It can also be provided, for example, that a surveillance camera of the building is only activated in the alarm state, in order for example to protect the privacy of people in or on the building, in particular in sensitive areas. For example, the pursuit of a fleeing shoplifter can also be provided.

In further embodiments it is provided that the computer unit and / or a superordinate point is or can be connected to further information acquisition means, in particular wherein the computer unit or the superordinate point is set up to acquire further information from the information acquisition means and this after transmission of the acquisition status of the person detection device to be taken into account together with them, in particular to determine and / or verify an alarm state. The further information acquisition means can include, for example, one or more sensors, cameras, microphones, fire alarms, etc.

A door system can in principle comprise several doors. A door can in particular comprise a, preferably motor-driven, door leaf, a person detection device and / or a door control. A higher-level point can, for example, be connected to the person detection devices and / or door controls of several doors.

The object of the invention is also achieved by a method according to the independent claim directed thereto. This relates to a method for operating a door or door system, in particular an escape and / or rescue route door or door system, in particular one of the type described above. The door or door system comprises a door leaf, in particular a rotating or sliding leaf. The method comprises that persons in the vicinity of the door leaf are detected in a detection state; that at least one normal detection state and / or one abnormal detection state is defined in which the detection state corresponds to a normal or abnormal person situation in the vicinity of the door; and that if the detection state deviates from the normal detection state or if the detection state corresponds to the abnormal detection state, an alarm state is determined.

The invention is explained below by way of example only with reference to the schematic drawings.

• 1 shows an exemplary sliding door system 10 for arrangement in an escape and / or rescue route.

The sliding door system 10 includes, for example, two door leaves 12th which can be automatically driven to an opening and / or closing movement, in particular by a motor, not shown here.

Above the door leaf 12th is a person detection device 14th arranged, which is designed here in particular as a motion sensor. The sliding door system 10 also includes a door control 16 , the example also above the door leaf 12th or the door is arranged. The person detection device 14th and the door control 16 are through a line 18th tied together.

The door control 16 is preferably set up to the door leaf 12th to open and / or close automatically by means of the motor, not shown. This takes place in particular as a function of one of the person detection device 14th , which is designed here in particular as a motion sensor, recorded the personal situation in front of the door leaves 12th . Typically this is done in such a way that the door leaves 12th opened automatically when at least one person is on the door leaf 12th approaching.

The door control 16 is over a line 20th with a superordinate body 22nd , in particular a building management system connected. The superordinate body 22nd is connected to further technical units, for example further doors and / or further information acquisition means, as is done here by several from the higher-level unit 22nd outgoing lines is indicated. The lines 18th and 20th and the other lines are illustrated here as direct connections, it being understood that the units shown can also be connected by means of other topologies, for example by means of one or more bus lines.

Escape and / or rescue routes, for example those with a sliding door system according to 1 , typically have sensors that recognize an approaching person, namely in particular motion detectors. In addition to the fact that there is movement, most sensors of this type can also determine other, in particular more specific, information relating to the personal situation without great effort. For example, the speed of at least one person can be determined. However, this information is currently not being processed.

In the event of an accident, e.g. fire, explosion, rampage, etc., panic quickly arises and people run towards the escape and rescue routes. The sensors recognize people in accordance with the standards and safely trigger the opening of the escape or rescue route so that those fleeing can pass unhindered. A message to a superordinate body, for example a building control system or security personnel, does not take place in the prior art. In particular, no distinction is made between whether people flee through the door or enter it normally.

In particular, if at least one person flees, or even if several people, in particular at the same time and / or in quick succession, flee through the door, it is proposed here to determine an alarm state and to output an alarm signal, in particular to forward it to a higher-level point. The higher-level body can then, for example, arrange for the area of the door in question to be viewed using security cameras or collect information from several sensors. In particular, this allows the alarm status to be verified. The superordinate body 22nd can in particular decide whether the police and / or rescue workers should be alerted and preferably alert them automatically. The evaluation can, for example, also take place via an artificial intelligence.

According to the invention, in particular a person detection device, for example a sensor, can be provided on an automatic door, which detects the speed of people passing and / or entering. A computer unit, which receives the detection status, can emit, for example, an alarm signal or a warning message as soon as one or more people pass the door faster than usual or run past the side. The alarm signal is forwarded in particular to a higher-level point and / or a door control. The higher-level unit can be, for example, a building management system, a security system, an AI or security personnel. In particular, the higher-level body can decide whether measures are necessary. The higher-level unit can, in particular for this purpose, combine several pieces of information, e.g. from a camera, another alarm device, another door and / or other sensors. The sensor can be, for example, a radar, ToF or ultrasonic sensor.

Regarding 1 The computer unit according to the invention, which determines the alarm status as a function of the detection status, can, for example, be in one unit with the person detection device 14th , as part of the door control 16 and / or as part of the parent body 22nd be arranged or formed. Over the lines 18th and or 20th or, for example, also via a bus, either the detection status or some of its data can thus be obtained from the person detection unit 14th can be passed to the computer unit and / or an alarm signal can be sent from the computer unit via the lines 18th and or 20th or a bus to the higher-level position 22nd be directed.
