B. the main closing edge leading photocells or light grid, it comes z. B. by rain, snowfall or strong sunlight increasingly frequently to temporary disturbances due to the interruption of the light paths, due to which the gate z. B. can not be closed by continuous reversing.

This also applies in connection with occupied or defective photoelectric sensors, which in addition to the contact closing safety edge z. B. must be used in the case of an automatic drive.

The invention has for its object to make the operation of an automatically driven door more convenient and yet safer.

To achieve this object, the invention provides a door drive control according to claim 1. A door drive system using this and a door provided therewith and a control method for this are the subject of the additional claims.

Advantageous embodiments are the subject of the dependent claims.

According to one aspect, the invention provides a door drive control for controlling a door drive, having a safety monitoring device which has a signal input for at least one obstacle sensor and / or for a force monitoring device for monitoring a drive parameter correlated with the drive force of the door drive and for switching off or reversing the door drive in dependence is formed by the signal input, and a deadman key circuit for operating the door drive in dead man's operation, comprising an integrated authorization device which is set up such that by authorizing a user, the security monitoring device is deactivated and the deadman key circuit is activated.

It is preferable that the integrated authorization device is a key switch integrated with a housing of the door drive controller.

It is preferred that a connection for an external authorization device is provided in addition to the integrated authorization device, wherein the dead-man key circuit is designed to perform dead man's operation by deactivating the security monitoring device on the basis of a signal of an external authorization device applied via the connection.

It is preferred that the door drive control is set up such that when an external authorization device is connected, the internal authorization device is deactivated.

Preferably, the door drive control comprises an external key switch as an accessory for connection to the external authorization device port.

It is preferable that the integrated authorization device has a user information device for informing a user of the operation of the authorization device and the deadman key circuit.

According to a further aspect, the invention provides a door drive system comprising a door drive, at least one obstacle sensor and a door drive control according to one of the preceding embodiments.

It is preferable that the obstacle sensor or at least one of a plurality of obstacle sensors is an optical sensor.

It is preferred that the obstacle sensor or at least one of a plurality of obstacle sensors is a resistance contact strip.

According to a further aspect, the invention provides an automatically driven gate comprising a door drive system of any of the preceding embodiments.

• Antreiben des Tores in einem Automatikbetriebsmodus unter Überwachung durch eine Sicherheitsüberwachungseinrichtung mittels eines Hindernissensors und/oder einer Kraftüberwachung und Anhalten oder Reversieren eines das Tor antreibenden Torantriebs bei Ansprechen der Sicherheitsüberwachungseinrichtung, und
• Antreiben des Tores in einem Totmannbetriebsmodus, bei dem der Torantrieb nur bei ständiger Betätigung einer Betätigungseinrichtung durch einen Benutzer läuft, wobei ein Umschalten von dem Automatikbetriebsmodus in den Totmannbetriebsmodus unter Autorisierung des Benutzers an einer an einem Torsteuerungsgehäuse integrierten Autorisierungseinrichtung erfolgt.

In another aspect, the invention provides a method for controlling an automatically driven gate,
full:

• Driving the gate in an automatic operating mode under surveillance by a safety monitoring device by means of an obstacle sensor and / or a force monitoring and stopping or reversing a the gate driving door drive in response to the safety monitoring device, and
• Driving the door in a deadman mode of operation in which the door operator runs only when a user operates an actuator continuously, wherein switching from the automatic mode of operation to the deadman mode of operation is performed authorizing the user on an authorizing device integrated with a gating housing.

Preferably, the door drive control according to one of the preceding embodiments is used for this purpose.

A preferred embodiment of the invention is a door drive control with integrated or externally connectable key switch / button for easy switching to deadman operation with occupied or defective safety device.

In contrast to known controls, which automatically switch to a deadman operation with occupied or defective closing edge safety device or after the repeated activation of the force limitation, such as in the DE 10 2013 017 987 A1 described, in the invention, no automatic switching to a dead man's operation is possible. With the invention it is ensured that the dead man's operation is permitted only for trained users and can be done in the public area only with a key switch / button.

In known controls that do not automatically switch to a dead man's operation, closing commands must therefore be given several times in succession and it is often a game of patience until you have closed the gate. When controlling in accordance with the invention, a user can close the door comfortably and simply, yet safely, with constant response of a safety device.

With the gate control according to preferred embodiments of the invention, a dead man's operation is possible only with a view to the gate and only for instructed user, so you can do without the described safety devices in this mode. In one embodiment, the deadman operation is additionally only in connection with a, e.g. in the public area or in the area with view to the door arranged external key switch / -taster possible.

The previously known door drive controls for this purpose usually have a programmable dead man's function, which excludes a self-holding operation in the same direction in this case. In addition, the instructed users usually do not know how to program this mode temporarily in the event of a fault, and even in the event that you know it, you must not perform the programming, as this expertise and the use of tools is necessary.

With embodiments of the invention, however, an easy to explain possibility / functionality is created, which ensures on the one hand, that the operation can always be done with a view to the gate and on the other ensures that the operation can only be done by authorized persons. For example, For this purpose, a miniature lock or optionally a profile half-cylinder (PHZ) sits in the control housing, which can be used to switch the operating mode in the event of an error to a deadman mode. In addition, an embodiment of the controller for this function has an additional output (terminal) for an external key switch. This is provided in the event that the controller can not or should not be mounted with a view to the gate.

An advantageous function of the control described here is: You get the goal z. B. in case of failure of a defective photocell closed without it must come to the "emergency operation" of a service technician.

It can be a simple and authorized switch to deadman operation in case of failure.

In the 1 . 4 and 5 are different embodiments for gate systems 10 shown, each having at least one automatic gate 12 have, which has a gate 14 , A partially not shown, but well known suspension for the gate 14 (For example, door frame), a door drive 16 for driving the automatic gate 12 and a door drive control 20 for controlling the door drive 16 having.

The automatic gate 12 each has at least one obstacle sensor 22 and / or a force monitoring device 24 on.

The obstacle sensor 22 is, for example, as a leading photocell 26 for securing a main closing edge 28 of the gate 14 or as a fixed photocell 30 or formed as a light grid (not shown).

The force monitoring device 24 detects at least one correlated with a driving force parameters of the door drive 16 so as to increase the driving force of the door drive 16 to monitor.

The door drive control 20 has a safety monitoring device 32 on, with the at least one obstacle sensor 22 and the force monitoring device 24 is connected to the door drive in an automatic operating mode 16 upon detection of an obstacle by the obstacle sensor 22 or shut down or reverse when an increased drive force occurs.

As in particular from the 2 and 3 can be seen, the door drive control 20 a housing 34 with housing cover 36 on.

On the housing cover 36 is an optional main switch 38 for switching on the door drive control 20 as well as the automatic gate 12 intended. Next are several controls 40 in particular comprising a key "OPEN" 42, a key "CLOSE" 44, a key "STOP" 46.

Next is on the case 34 , in this embodiment, on the housing cover 36 , an integrated authorization device 48 intended to authorize an authorized user. The integrated authorization device 48 is for example as a key switch 50 , here, for example, a mini key switch, or a profile half cylinder with signal function, provided.

Next is the door operator control 20 near the integrated authorization facility 48 , a user information device 52 for informing a user about the operation of the integrated authorization device 48 and their function provided. For example, the user information device 52 a corresponding informative text. Particularly preferred are pictograms. The User information equipment 52 could also have a display.

In the embodiment of 1 indicates the gate system 10 an automatic gate 12 in the form of a sectional door, in particular an industrial door, on. The door drive control 20 is in this case arranged so that the gate 14 from the door drive control 20 can be seen from.

In 4 is an example of a gate system 10 shown, with several automatic gates 12 are provided, which via a door drive control 20 are controllable. One of the automatic gates 12 and in particular their gate wings 14 are from the door drive control 20 off not visible. This is here by a partition 54 indicated. In this case is in an area from which the gate wing 14 this automatic door 12a can be seen, an external actuator 56 intended. The external actuator 56 in particular, an external authorization device 58 exhibit.

The external authorization device 58 in particular, an external key switch 60 exhibit. The external actuator 56 with the external authorization device 58 is the door operator control 20 especially assigned as an accessory.

5 shows another example of a gate system 10 Being as an automatic gate 12 a Hofschiebetor is provided and wherein the external operating unit 56 is arranged at a public area.

Here is the external actuator 56 also the external authorization device 58 , in particular in the form of the external key switch 60 , on.

Of course, the respective authorization device 48 . 58 not only be designed for operation with a key, there are also code keypad, finger reader or other biometric sensors, smart card reader, RFID reader, NFC sensors, etc. conceivable.

In 6 is a block diagram of a first embodiment of the door drive control 20 shown.

The door drive control 20 therefore indicates the security monitoring device 32 via the sensor connections S1, S2 with obstacle sensors 22 is connectable, via a position sensor terminal P with an absolute value encoder or the like position sensor for the position and / or the speed of movement of the door leaf 14 can be connected and further by monitoring an electric motor of the door drive 16 , indicated via terminals +, - for the motor M for monitoring the power, the current or other parameters correlated with the force of the door drive 16 is available. The designation of the terminals +, - is particularly advantageous for DC motors. If the motor M has a different design, such as for rotary or alternating current, the corresponding number of terminals with corresponding designations (L1, L2, L3, ~) may be provided.

Next, the door drive control 20 an automatic mode control unit 62 on, which is used to control the door drive 16 is set up in an automatic mode. The automatic mode control unit 62 is with the security monitoring device 32 connected to the door operator 16 stop or reverse in case of detection of an obstacle or detection of an inadmissible force. Next is the automatic mode control unit 62 with the controls 40 connected, in particular with the key "OPEN" 42 and the key "CLOSE" 44. Next is the automatic mode control unit 62 with a radio receiver 64 connected. In the illustrated embodiment, the automatic mode control unit 62 also via a connection 66 , For example, a plug connection for cable or the like, with the external actuator unit 56 and in particular the external authorization device 58 be connected.

The door drive control 20 indicates further according to 6 a dead man's circuit 68 for performing a deadman operation mode. The dead man's circuit 68 is with the integrated controls 40 , in particular with the key "OPEN" 42 and the key "CLOSE" 44. Next is the dead man's circuit 68 with the connection 66 connected to it to the external actuator unit 56 and in particular the external authorization device 58 to join.

The security monitoring device 32 , the automatic mode control unit 62 and the dead man's circuit 68 are eg as software within a data processing unit, for example a CPU module, within the door drive control 20 realized. The design of the software will become clear to the person skilled in the art on the basis of the functions of the individual units explained below.

In an automatic mode, the automatic mode control unit is 62 active. Here is the door drive 16 by a command pulse in motion, whereupon the gate 14 over the door drive 16 in the desired direction under the supervision of the safety monitoring device 32 is moved.

For example, via the radio receiver 64 a command is initiated, whereupon a closed gate moves to the open position. After an automatically set hold time, the door can automatically return to the "CLOSE TO" position. Here are the obstacle sensors 22 active. If an obstacle is detected, the door drive becomes 16 stopped or reversed.

As obstacle sensors 22 Preferably optical sensors or other non-contact sensors are used because they avoid any contact with the obstacle and thus can safely exclude damage or injury. However, such obstacle sensors are 22 also quite vulnerable to interference. For example, it may be due to snowfall or other weather conditions to interrupt a light path of a light barrier 26 to lead.

Also, it can in winter, especially with sliding gates, weather-related to a heavier gear of the gate 14 come, so that to open an increased driving force for the door drive 16 is necessary, which is not caused by an obstacle or the like. In these cases, the security monitoring device would 32 although there is no danger of obstacles or the like.

In an automatic mode, a pulse would then have to be entered again, but this sometimes leads to a shutdown by the safety monitoring device 32 can lead.

For this reason, the integrated authorization device 48 designed to be the automatic mode control unit 62 inactive and the dead man's circuit 68 active.

The dead man's circuit 68 is designed such that the door drive 16 only then is set in motion and set in motion, if a corresponding actuator 40 is constantly pressed. For example, in the deadman mode, which by the dead man's circuit 68 to carry out by a user constantly the key "CLOSED" 44 to press, so the gate 12 close. If the user leaves the "CLOSE" key 44 go, immediately stops the door drive 16 ,

Instead of the integrated controls 40 may also be an external actuator in one embodiment 56 for the deadman operation by the deadman circuit 68 to be used.

In one embodiment of the door drive control 20 is the dead man's circuit 68 designed such that when connecting an external authorization device 58 a deadman operation only via the external authorization device 58 and not via the integrated authorization facility 48 or the integrated controls 40 is possible.

This is intended for situations like those in 4 is shown where the location of the door drive control 20 no view of the gate 14 is possible. This ensures that a deadman operation when installing the door drive control 20 in the viewing area conveniently via the integrated authorization device 48 can be activated, but when mounted outside the field of view is prescribed, the external authorization device 58 to accommodate in the field of vision. In this embodiment, the deadman operation is then exclusively via the external authorization device 58 possible.

Activation of the dead man's circuit 68 and inactivation of the security monitoring device 32 is exclusively via at least one of the authorization devices 48 . 58 possible.

7 shows a further embodiment of the door drive control 20 , which in many parts of the embodiment of 6 equivalent. The only difference here is that a switching unit 70 with which of the automatic mode control unit 62 on the deadman circuit 68 and vice versa, both with the integrated authorization device 48 as well as with the external authorization device 58 is operable.

In this embodiment, it can be provided that the external authorization device 58 on a short operation or in a first position, a pulse for driving the automatic mode control unit 62 and upon prolonged actuation and / or continuous operation in a second position, the automatic mode control unit 62 inactivated and the dead man's circuit 68 is activated and at the same time the deadman operation is initiated.
