Definitions

  • the invention relates to an access monitoring device of an elevator installation having at least one video unit, wherein the at least one video unit is connected to a control unit via a communication network.
  • Some buildings require access control to prevent certain parts of the building from being open to the public. In many buildings, this access control can be found at the entrance to the building. However, many larger buildings, such as office buildings, shopping centers, residential buildings, etc., have parts of the building that are also supposed to be open to the public, while other parts of the building should only be accessed by certain persons, for example because of a higher level of security for these parts of the building should apply. For example, the ground floor of a building may be accessible to the general public, but the upper floors are private and should not be made accessible to the general public, or only under certain conditions.
  • the European patent application with the application number 10167984.3 describes an elevator security system for an elevator system comprising at least one elevator car.
  • the system includes an access monitor that detects an unauthorized individual within a defined area and outputs a signal.
  • the output signal is used to block the use of the elevator system.
  • elevator installations installed in the buildings may be restricted. It can be tried, for example, by means of locks, locks, access controls, hubs, security personnel, etc., that unauthorized persons can reach and use the elevator system.
  • Such devices can be referred to as access monitoring device or access control device.
  • An object of the invention is to propose a cost-effective and efficient access control device.
  • a core of the invention is that with the aid of at least one video unit in an access monitoring device of an elevator system detects the presence of an object in a defined monitoring space of the access monitoring device and determined data or determined by the at least one video unit evaluation result, the direction of movement or the location of the object is determined within the interstitial space. In addition, depending on the data determined, the authorization of the object can be checked.
  • the access monitoring device for example a barrier, a lock, a virtual line or barrier area, etc., of an elevator installation serves to prevent or hinder the access of unauthorized objects, for example persons, visitors, animals etc., to an elevator installation.
  • It has for this purpose at least one video unit, which is connected via a communication network with a control unit.
  • the communication network used can be arbitrary.
  • a wireline, wireline or radio communication network could be used.
  • the control unit may be integrated in the video unit or constitute a separate unit. It is also conceivable that the control unit represents a partial function of the elevator control unit of the elevator installation, that is, that the control unit is integrated in the elevator control unit.
  • the at least one video unit receives at least one image from a defined monitoring space of the access monitoring device.
  • the interstitial space can be, for example, the passage in a lock.
  • the vestibule of the access monitoring device could also be defined as a surveillance space.
  • the surveillance space may also be defined in the form of a virtual surveillance area in a building.
  • any analog or digital video unit may be used, and may be, for example, a commercially available surveillance camera, a video camera, etc.
  • the at least one video unit has at least one image recording unit and an image processing unit or an (integrated) control unit for at least partial image processing.
  • the at least one video unit may be connected to the (external) control unit via the communication network.
  • a control unit a processor, a computer, a commercially available computer or server with commercially available components and, for example, with a storage unit can be used.
  • the control unit integrated or external, performs image processing. In this case, suitable algorithms and methods are used.
  • the entire image processing is carried out in the at least one video unit or in the (external) control unit connected via the communication network. But even a partial image processing in the integrated control unit and a final image processing in the connected via the communication network (external) control unit is conceivable.
  • a non-changing image part is filtered out.
  • This may be, for example, the background, a non-moving object, etc.
  • the image parts are filtered out, which have no relevance for evaluation. Remain those parts of the image, which are for the detection of an unauthorized object in the interstitial space of interest.
  • the non-changing image part of the at least one image can be filtered out, for example, by the at least one video unit comparing the at least one current image with at least one previously recorded image.
  • at least one suitable image i. H. a reference image is used in a storage unit connected to the control unit via the communication network.
  • the memory unit can also be integrated in the control unit.
  • the at least one video unit evaluates the at least one remaining image part. It checks whether there is an object or object of interest in the interstitial space. If an object remains in the interstitial space, the at least one video unit transmits data to the control unit. For this purpose, the at least one video unit transmits as data, for example, the evaluation result or the evaluation result with the remaining image part or only the remaining image part of the at least one image to the Control unit. The at least one video unit can thus cumulatively or alternatively send the remaining image part of the at least one image with the evaluation result to the control unit.
  • the control unit checks the authorization of the object located in the monitoring space depending on the transmitted data and determines either the direction of movement or the location of the object within the surveillance space. By detecting the direction of movement or the location of the object, a statement can be made as to whether the object attempts to reach an area of a building secured by the access monitoring device or whether the object is only in front of the access monitoring device, for example. If the object has no authorization for the secured area or if authorization is denied, a warning signal or alarm, for example an optical signal, an acoustic signal or a combination thereof, can either be output via a signaling unit or at least one message can be output sent to a security center.
  • a warning signal or alarm for example an optical signal, an acoustic signal or a combination thereof, can either be output via a signaling unit or at least one message can be output sent to a security center.
  • the access monitoring device may comprise at least two video units.
  • the at least one first video unit can be in the field of view of the at least one second video unit.
  • manipulation attempts for example by covering the video unit, can be avoided.
  • the at least one first video unit and the at least one second video unit are arranged opposite one another.
  • the video units can be arranged in a sluice or in the access monitoring device parallel or perpendicular to the passage direction.
  • the at least one first video unit and the at least one second video unit can monitor the surveillance space from different angles.
  • the at least one first video unit may be connected to the at least one second video unit via the communication network directly or indirectly via the control unit.
  • the control unit can check the authorization either on the basis of at least one detection signal or authorization and authentication date or signal transmitted by an authorization and authentication unit or according to at least one rule.
  • an authorization and authentication unit any unit for detecting or reading in the at least one detection signal, such as biometric data, a code consisting of numbers, letters, special characters or a combination thereof, on a RFID unit stored detection signal or authentication date or identification date, a picture, etc. are used.
  • the inventive at least one video unit could be used for facial recognition or for the acquisition of biometric data and thus for authorization and authentication.
  • An advantage of the invention is the fact that in a simple and cost-effective manner, an unauthorized object can be detected in a monitoring room of an access monitoring device.
  • FIG. 1 shows a schematic representation of a secure with an access control device S area AZVR, for example, an elevator lobby as access to individual lifts AZ and to a door T in a building.
  • the secured area AZVR is separated from the publicly accessible area OEB by the access monitoring device S.
  • the access monitoring device S has boundaries SW, for example columns, lock walls, markings on the floor of the building, etc., on. In this example, the access monitor S has multiple passes. However, the access control device S may have only one passage.
  • the access monitoring device S has at least one Video unit K or a video camera which monitors at least one defined monitoring space UER of the access monitoring device S.
  • the at least one video unit K is arranged opposite the access monitoring device S for this purpose.
  • the at least one video unit K can also be arranged in the boundaries SW. Thus, the at least one video unit K could monitor a defined monitoring space between the boundaries SW.
  • the at least one video unit could not be arranged permanently, but as needed in the access monitoring device or in the access monitoring device.
  • at least one device and / or a corresponding interface for the connection to the communication network and / or assembly / disassembly of the video unit could be provided in the access monitoring device S or in the limitations SW.
  • FIG. 2 shows a detail of the access monitoring device S.
  • the access monitoring device S separates the publicly accessible area OEB of a building from a secured area AZVR or a non-publicly accessible area. For the separation of the areas OEB and AZVR limits SW of the access monitoring device S are used. Between the two boundaries SW the monitoring space UER is shown, which is monitored by at least one video unit K not shown in this figure.
  • FIG. 3 shows a detail of the access monitoring device S from the Figures 1 and 2 with possible directions of movement of an object.
  • the rectangle between the boundaries SW shown in dashed lines is intended to represent the surveillance space UER.
  • two video units K1 and K2 are arranged so that they can detect movements of objects such as persons, animals, etc. in the surveillance space UER.
  • the video units K1 and K2 are integrated in the limits SW in this example.
  • Shown are possible directions of movement 1 to 4 of objects which move into the secured area AZVR or from the secured area AZVR.
  • the direction of movement 4 may be an object which attempts to reach the secured area AZVR, but for example by means of a warning signal of at least one in the boundaries SW signaling unit is made aware that there is no authorization. Then this object moves out of the secure area AZVR again.
  • FIG. 4 shows a schematic representation of an access monitoring device S with, for example, two video units K1 and K2.
  • An object O is located between the boundaries SW of the access monitoring device S.
  • the two video units K1 and K2 monitor the intermediate space, the defined surveillance space UER, between the two boundaries SW.
  • the first video unit K1 is in the field of view of the second video unit K2 and vice versa. This can be prevented, for example, that a video unit K1 or K2 is manipulated.
  • a signaling unit SE is integrated, which can output at least one optical and / or acoustic signal, for example, when an object O in the interstitial space UER and this object O has no authorization for this, ie an authorization refusal or a negative check result was determined by the control unit ST.
  • the two video units K1 and K2 are arranged opposite each other and are connected to a control unit ST via a communication network. Any communication network can be used as communication network. So z. For example, a wireline, wireline and / or radio communication network may be used.
  • the two video units K1 and K2 can also be connected via the communication network, be it directly or indirectly via the control unit ST.
  • the two video units K1 and K2 monitor the surveillance space UER from different angles. In this example, this is done by placing the two video units K1 and K2 opposite one another. This has the advantage, for example, that the direction of movement or the location of an object O within the surveillance space UER can be determined more accurately.
  • a video unit K, K1, K2 could also be positioned in such a way that, for example, it authenticates or identifies the object O by means of facial recognition or recognition of biometric features.
  • the access monitoring device S may have an authorization and authentication unit KL.
  • This unit (KL) can also be used to identify an object O.
  • the authorization and authentication unit KL detects at least one detection signal, for example a biometric signal, an authentication date stored on an RFID card, data for identifying an object etc. and transmits the at least one detection signal in at least one message to the control unit ST.
  • the at least one authorization and authentication unit KL can, as in this example, be arranged on the boundary SW of the access monitoring device S. However, it (KL) can also be positioned in another location or their functionality can be perceived by the at least one video unit K, K1, K2.
  • the control unit ST may check the authorization of an object O based on a comparison with stored data.
  • the authorization can also be determined as a function of at least one rule.
  • a rule could be that objects O that leave the secure area AZVR receive an authorization release.
  • Another rule could be that authorization is always granted at certain times.
  • Yet another rule could be that in the case of no message from the authorization and authentication unit KL, the control unit ST accepts an authorization refusal and issues a negative verification result.
  • a signaling unit SE connected to the control unit ST output a warning message.
  • This warning message can consist of optical and / or acoustic signals.
  • the control unit ST can also send in case of an authorization refusal or in the absence of authorization at least one message to a connected via the communication network security center SZ.
  • the security center SZ can be, for example, a unit of a security center outside or inside the building. With the at least one message received at the security center SZ then appropriate measures can be taken, such as that a security guard for access control device S is posted that at least one of the video units K, K1, K2 receives at least one more image of the object O etc.
  • FIG. 5 shows a further schematic representation of an access monitoring device S with two video units K1, K2.
  • the access monitoring device S is, as in FIG. 4 described, constructed, points.
  • the at least one authorization and authentication unit KL and the at least one signaling unit SE have been omitted for reasons of clarity.
  • the difference to FIG. 4 is that the two video units K1 and K2 different to FIG. 4 are arranged.
  • the arrangement of the two video units K1 and K2 can basically be arbitrary. It only has to be ensured that the surveillance space UER can be monitored by the video units K1 and K2. This also applies if only one video unit K, K1, K2 is used.
  • FIG. 6 shows a schematic example of image processing with two video units K1 and K2.
  • the exemplary method for image processing can also be applied to access monitoring devices S with only one video unit K, K1, K2 or with more than two video units K, K1, K2.
  • Each of the two video units K1 and K2 receives a respective image BN, BN-1, BN-2 at a time interval N, N-1, N-2 or continuously in this example.
  • the two video units K1 and K2 each record only one image BN.
  • Each of the two video units K1 and K2 filters out a non-changing image part from the images BN, BN-1, BN-2.
  • This unchanging part of the picture can be, for example, the background.
  • the remaining image part BGN, BGN-1, BGN-2 of the respective images BN, BN-1, BN-2 is evaluated to see whether there is an object O in the monitoring space UER.
  • An object O passes through the access monitoring device S with the boundaries SW and the video units K1 and K2, as they (S) in the FIGS. 1 to 5 is described.
  • data is transmitted to the control unit ST.
  • the Evaluation result or the evaluation result and the remaining image parts BGN, BGN-1, BGN-2 of the images BN, BN-1, BN-2 or only the remaining image parts BGN, BGN-1, BGN-2 of the images BN, BN-1, BN-2 or images BN, BN-1, BN-2, etc. are used.
  • the entire image BN, BN-1, BN-2 is transmitted to the control unit ST and there is the entire evaluation, ie it is filtered out by the control unit ST of the non-changing image part and it is also the detection an object O in the surveillance space UER of the control unit ST.
  • the transmission of the data ie the evaluation result and / or the remaining image part BGN, BGN-1, BGN-2 is, as already mentioned, ideally only when an object O has actually been detected in the monitoring space UER. In the case of a negative evaluation result, i. H. there is no object O in the monitoring space UER, no transmission could take place.
  • the image parts BGN, BGN-1, BGN-2 or the entire images BN, BN-1, BN-2 are transmitted to the control unit ST.
  • the control unit ST checks in dependence of the transmitted data from the two video units K1, K2 the authorization of the object O in the surveillance space UER. It is thus checked whether an object O is in the surveillance space UER and if so, then the control unit ST checks the authorization of the object O in question.
  • the authorization check is performed either on the basis of data from an authorization and authentication unit KL or according to at least one rule as in the preceding FIGS. 1 to 5 is described. For example, the direction of movement or the time could apply as at least one rule. Thus, it could be regulated that if an object O leaves the secure area AZVR, no authorization is required. Also, at certain times no authorization could be required.
  • the direction of movement 1, 2, 3, 4 or the location for example, the object O in the interstitial space UER standing, the object O within the interstitial space UER determined.
