Access control device

The invention relates to a Access control apparatus according to the preamble of Claim 1. Such a conditional access device is known from AT-U-6665th As a blocking element to a Revolver with a tilted relative to the horizontal Axis of rotation and two an angle of approximately 120 ° and 240 ° enclosing blocking arms used, as known from EP-A is 961,005 known.

Here are the locking arm in its basic position access free. In contrast, if a person is detected without a valid reading of access authorization is done, the blocking arm is rotated in the access to him to block.

Thus the locking arm from the initial or "Open Gate" position can be pivoted into the blocking position before a detected person without a valid reading of Admission reaches the hub, have the Access authorization reader and the people sensor arranged correspondingly large distance from the hub will. Thus, a person who the happened access authorization reader without access authorization has put before the then access blocking barrier arm and wait until the access by a subsequent further Person is released with a valid access authorization. Since the triggered by the other person enable signal To open the lock on the person without Access authorization has been used, is for Another person with valid access authorization access blocked. This problem is exacerbated by that it is not only in individuals without access authorization occurs, but to become more common in that a valid access authorization can not be read, For example, because in the reading of contactless acting RFID transponders, the transponder z. B. in a Pocket of the person by objects is electromagnetically shielded.

From US 6,617,960 B1 is an access control device two access tracks with recording equipment in the center, the on both sides of a rotating star with two 180 ° having staggered locking arms, and two non-contact acting conditional access readers on the outsides known.

The object of the invention is to provide an access control device referred to in the preamble portion of claim 1 provide, with which it is ensured that, while Persons with a valid reading of an access authorization, the can lock happen, but not persons with invalid reading.

After the first access authorization reader is in Passage direction, a second access authorization reader provided. The second access authorization reader is preferably in a range of the blocking element, in the a valid access authorization before a Blocking element standing person, the person sensor to has already passed, from the second can be read access authorization reader.

The control of the actuator that moves the locking element, z. B. designed so that under normal conditions, ie at valid reading of an access authorization to the first Access authorization reader the first Access authorization reader the actuator so controls that the access is enabled ( "open gate" operation).

If the "open gate" operation on the other hand with the People sensor detects a person, without the first access authorization reader a valid Access authorization is read, the access to the will Blocking element is blocked and at the same time, the actuator instead of the first access authorization reader of the second driven access authorization reader, of the area in The blocking element is provided.

Then, when a valid reading of access authorization by the second access authorization reader is done, is the released access from the blocking element and the actuator instead of the second access authorization reader again the first access authorization reader driven.

If on the second access authorization reader no valid access authorization is read, the access remains for the detected person without a valid reading the first and second access authorization reader blocked. she can access to make it in the opposite direction leave or may be by means of control staff remove, z. B. by a manual release of Enforcement staff.

The actuator is preferably a motor, in particular a Electric motor. However, he may, for. Example, by a Electromagnets, one by a pressure medium, z. B. Compressed-air actuated piston / cylinder unit or be like.

The access control apparatus according to the invention can be used as Turnstile be formed, for example, a Turnstile as a blocking element. The turnstile has preferably only one or two locking arms on. The Blocking element, an opposite example, by about 35 ° the horizontal inclined axis of rotation with a single Blocking arm or two an angle of approximately 120 or 240 enclosing locking arms reject as WO 97/18379 from and from EP-A-961 005 is known, or a vertical Rotational axis with one or two blocking arms according to WO 97/18379.

The release and blocking of access is According to the invention not only mechanically to understand but as a logical process. Thus, the blocking element z. B. also by an optical and / or acoustic signal transmitter are formed, for example, a green light for Released and a red, indicating the blocking.

Under invalid reading of an access authorization is not only the case to understand, in which the controlled person no access authorization has, but also the case, wherein a valid access authorization is present, however, is not covered by the access authorization reader.

The two access authorization reader are preferably formed by contactless readers in particular the reading of RFID transponders with stored thereon Access authorization. Access may also Reference filed for in a database, by Be the control device retrievable admission. To capture the entire width of the entrance lane, can the first and / or second access authorization reader each an antenna on both sides of the entrance lane exhibit.

In the area of ​​the blocking element, an additional his access authorization reader provided a blocked access z. B. with a magnetic, barcode or like being able to open ticket that the Access authorization reader is plugged.

While in some applications, for example a Ski lift the access control apparatus generally only in one direction has to be passable, are Access devices to a demarcated area passable often formed in both directions. In the latter case, preferably on both sides of the second access authorization reader a first Access authorization reader are provided, so a reader If the inspected person in the one or the other Passage direction detected before the second to the Access authorization reader in the area of ​​the blocking element arrives.

The person sensor, for example, as optoelectronic sensor be formed. Preferably be at least two people in front of the sensors Blocking element provided. This firstly the risk a faulty signal, for example by Items such as ski poles, prevented, secondly, that Clinging to each other two people with only one Admission the access control apparatus happen.

Further, preferably a passenger sensor according to the Blocking element provided. is this person sensor For example, a person recognized by one hand Jam to the access control apparatus not can move. The locking element may then in the locking position are held until the people sensor according to the Blocking element no further than a given period Lingering Person longer recorded.

Another person sensor can in the area of be blocking element provided. In a carousel as Locking element, this person sensor detects a person in the detect access level of the lock arm and where appropriate a rotation (push) the person by the rotary arm trigger.

The one or at least two sensors in front of the Blocking element, the people in the field of sensor The locking element and the people sensor after the locking element may have different Abtastcharakteristiken and / or a different scan angle with the Include access direction. That is, they can be a have narrow or wide Abtastkeule. Thus, for. Example, the People sensor before the blocking element a narrow have Abtastkeule, to prolong the passing time the detected person to reach up to the locking element.

The motor may for driving the locking member in both Directions of rotation are controlled. This allows, for. Example, be prevented that a person from the People sensor is detected by the locking element, because they remains there, a blow through the locking element of Rear learns. Even so can passing the Access control apparatus in both directions bill be taken, in the preferred direction of rotation locking arm is moved against the direction of passage.

The actuator may be controlled such that the Blocking element in the normal position in the from the Access track moving release position is, therefore, the has released access, before the reading of the Admission to the first Access authorization reader is performed ( "Open Gate" position).

If the access in the normal position is released, however, there is the danger that too controlling the People are encouraged to, the Access control apparatus at high speed happen, for example, by retracting a skier at high speed in the access control device on a ski lift.

If no valid access authorization of the first read access authorization reader and thus access is suddenly blocked by the blocking element, can the Skier at high speed on the locking element are incident and violated.

To mitigate the consequences of such an impact, can Locking element, ie z. B. the locking arm of a rotating arm, with padding provided and / or formed resiliently be such. as from a rubber-elastic material.

However, it can also be an optical or acoustic Signal generator can be provided which a blocking and possibly indicating the release of access.

An optical display can also be characterized realize that the blocking element, ie z. B. the Locking arm of a rotating arm in the release position the Although access is free, but more or less in the is access track moves. This also is a psychological barrier to rapid retraction in created the access control apparatus, so be warned, that the barrier arm completely swung into the entrance lane and they can block it. To a in Release position pivoted slightly in the entrance lane Blocking arm indicate that the first Access authorization reader a valid access authorization has read, the locking arm from the access track can very be moved out if a valid reading of Admission to the first Access authorization reader is done.

In order to prevent that a person by the Release position of the blocking element before passing the first Access authorization reader is encouraged to come up with high speed through the access control device move, the actuator also from the outset may otherwise be controlled, namely for a separation operation in such a way that the blocking element in front of a valid reading Admission to the first Access authorization reader, that is in the normal position, the blocked access and valid only after reading the first access authorization reader releases. One with high speed on the access control device to moving person sees thus the by the blocking element blocked access and its speed reduced accordingly. To avoid falling into the locking element to come contact, in this case, the locking element after valid reading the first Access authorization reader but moved out of the access, before the person reaches the blocking element.

It is also possible, the motor selectively between the "Open Gate" operation and the separating operation, wherein the access in the normal position is blocked to control, So between an operation in which the blocking element to Access before reading the access authorization to the first Access authorization reader frees and after invalid Reading with the first access authorization reader and Detection of a person by people sensor access blocked or an operation in which the blocking element before valid reading of an access authorization to the first Access authorization reader blocking access and only after valid reading the first Access authorization reader releases. Thus, for. Example, in a Ski lift in the first few hours of the day of Separating operation and then the "Open Gate" operation for performed the rest of the day.

It is also possible between the two operating modes to automatically switch back and forth. Thus, it would imagine that as long as a regular flow of people present, the "Open Gate" operation using place, since in this case, rapid retraction not with skis is possible. Tear the People column but from may with a time lag to the blocking operation be switched. The spar is blocking access. This so long until more people back to the normal Passage start. Thus, one has the two advantages Open Gate (no disability) and protection from fast Entrance (risk of accident) united.

Preferably, as the locking member is a rotating star with a single barrier arm used. This is a barrier arm can in the release position, so twisted in his down Position, obliquely from the access way extending downward compared, for example with an angle of 10 ° or more the vertical. This takes the place of the entrance lane in the release position of the star of its axis of rotation down to, so that a particularly convenient passage is achieved.

When a person sensor is provided, which in a person the barrier layer, so recorded in the vertical plane, in of a locking arm in the on access extending is upturned locking position, can the locking arm from the release position upon detection a person with this sensor in a waiting position be rotated, so something in the direction of locking position, However, without access to block.

If the access control device Separating operation is set, then the can Locking arm from the waiting position into the locking position be turned, whereby the person in to slower rate of passage easily with the locking arm can be pushed.

In an "open gate" operation of the locking arm can to valid reading of access authorization to the first Access authorization reader from the waiting position again the release position be rotated back to the display controlled person sharing.

Alternatively, the barrier arm when reading from invalid the Lauerstellung rotated faster in the locking position be as if a rotation from the release position to the locking position has to be performed.

In order to prevent that when "open gate" mode, Blocking element despite invalid reading, z. B. with ski poles is forcibly maintained in the release position, a be provided alarm device such at a violent blockade of the blocking element is actuated.

Below is the inventive Access control device based on the drawing exemplarily explained in more detail. Therein is shown schematically

Figure 1 and Figure 2 is a perspective view of a Conditional access device in the release position or Blocking position and

Figure 3 shows another embodiment with two antennas at the first access authorization reader.

According to Figure 1, an access control device as Turnstile trained blocking element 1 on which a Actuator in the form of a phantom motor shown 2 is driven. The locking element 1 is equipped with two Blocking arms 3, 4 to lock access 7 provided that in Direction of the arrow 5 happened.

The locking element 1 is a horizontal to a Angle of about 35 ° sloped axis 6 rotatably. The angle, to the blocking arms 3, 4 form with the axis of rotation 6, is in each case approximately 45 °. The angle α, both the Blocking arms 3, 4 form with one another, is about 120 °.

While in the release position shown in Figure 1 both locking arms 3, 4 is pivoted approximately vertically downwards are such that the access 7 is released, is Rotation of the barrier element 1 according to the arrow 8 'of the Locking arm 3 is pivoted into the horizontal position and lock so that access 7 blocks, as shown in FIG. 2

The access control apparatus comprises a frame 8, the a housing bears. 9 In the housing 9 of the motor 2 arranged; also it takes for the operation of the Rotary member 1 and the engine 2 necessary components, such as the storage and the drive gear of the rotary member 1 and that the electronics for controlling the motor 2.

On the housing 9, a further housing 11 is attached, the is arranged in the direction of access 5 before the housing. 9 In the housing 11 and the casing 9 is in each case a dashed illustrated RFID reader module 14 and 15 with an antenna 12 or 13 is provided. Instead of two separate reading devices, the two antennas 12 and 13 also be connected to a single reader module between the reception with the antenna 12 and the reception of the antenna 13 is switchable. It is therefore decisive that two in the direction of access 5 arranged in succession Antennas 12 and 13 are provided.

With reading modules 14 and 15 to the antennas 12, 13, the Access authorization is read without contact, which in a transponder is stored as disk that the access authorized person carries with him.

Further, between the first antenna 12 and the second Antenna 13 z. B. in the housing 9, an optoelectronic disposed persons sensor 16th

In the first access authorization reader 14 from Disk read access authorization is access 7 released, as shown in FIG. 1 In order for a sufficient time to read the disc available stands before passing into the access 7 person the achieved locking element 1, the antenna 12 of the first Access authorization reader 14 at a distance of A for example, 20 to 60 cm in front of the blocking element 1 appropriate.

When the first access authorization reader 14 a valid Admission reads, the blocking element 1 remains in the Release position shown in FIG. 1 Happens however, a person without a valid reading of a Admission to the first access authorization reader 14 and the people sensor 16, the locking element 1 in which is pivoted in Figure 2 illustrated blocking position.

The person making the antenna 12 of the first Access authorization reader 14 without a valid reading and has passed person sensor 16, so that is before the Blocking position rotated lockout arm 3 shown in FIG 2. can wait there until the access 7 by a second subsequent person with valid access authorization is released.

To prevent this, according to the invention at a invalid reading of access authorization to the antenna 12 of the first access authorization reader 14 and detection a person with the person sensor 16 of the first Access authorization reader 14 to the antenna 12 off and the second access authorization reader 15 switched to the antenna 13 and thus of the previously the first access authorization reader 14 controlled motor 2 now from the second access authorization reader 15 driven. An access authorization of a person who the standing in front of the closed barrier arm 3 person followeth, so is of the first Access authorization reader 14 to the antenna 12 no longer detected.

Instead, the access authorization of before is closed barrier arm 3 person standing still again with the second access authorization reader 15 to the antenna 13 checked. If during the re-examination a valid access authorization to the second read access authorization reader 15, is the second Access authorization reader off and the first Access authorization reader 14 is turned on again to the Motor 2 to drive.

Furthermore, it is within range of the locking element to the housing 1 9 an access authorization reader 19 for reading insertable, Eg. With contacts disk provided. Thus, the turnstile be opened by persons who only on such a disk can be inserted with a Access authorization feature.

To the entire width of the entrance lane 7 with the first to detect access authorization reader 14, is shown in FIG 3 on the opposite side of the access lane Another housing 17 with a dashed illustrated Antenna 12 'is provided, the first to the Access authorization reader 14 is connected.
