Description

The invention relates to a building or enclosure closure device according to the Preamble of appended claim 1, a drive device according to the preamble of the attached claim 2 for such a building or Enclosure closure device and a control device according to the preamble of appended claim 3 for controlling and / or controlling such Drive device and a method for operating such devices.

Such devices are, for example, motorized in those already on the market powered gates become known. To control and monitor known Doors already have electrical components arranged on the door leaf Service. These electrotechnical components are a control device assigned to the control of a drive, for example. These are often around the connection devices of sensors or the like Detection devices that detect the movement of the wing, in particular the opening for obstacles. This is done, for example, in the form of a Closing edge safety device of known type. In this case, a compressible rubber strip used, inside of which one by means of a Photoelectric sensor formed is located. Will this rubber strip for example Colliding on an obstacle, this is done via the light barrier detected. In such a case, the drive should either stop immediately or reverse be put into operation or not put into operation at all.

Whenever you have control units or registration units directly on the door leaf or another motor-driven movable wing of a building or Orders completion of the fencing, which is often very desirable for security reasons, there is also a need to control these sensors or the like supply electrical energy on the one hand and Signal transmission to the usually stationary drive controls sure. For this purpose, the fixed and mobile electrotechnical units in known gates or the like means Cables or sliding contacts connected together. These cables or sliding contacts are on the one hand expensive, prone to wear due to their movement and often difficult or unwieldy to assemble. If there are connection errors during assembly, this can happen to destroy one or the other electrotechnical, especially electronic Lead unity.

The object of the invention is to provide a device in the preambles of the independent to simplify the enclosed claims specified type with regard to installation and maintenance. Also, the life of the device should be increased, its manufacturing and Installation costs reduced and negative consequences due to assembly errors avoided.

This object is achieved with devices according to independent claims 1, 2 or 3 solved.

Wireless connection devices between fixed and moving on the wing Up to now, units have hardly been found in practice. In addition to reliability problems here in particular to solve the problem of the energy supply of traveling units. The invention addresses this problem in particular in that a pulsed Operation for the traveling units is proposed. The units are e.g. constantly switched between an energy-saving mode and an active mode, to minimize the total active time and thereby save electricity. It works especially when the wing is at rest. Here asks one Execution of the traveling transceiver unit for a short operating time Existence of an activating state and then switches off for a "longer" time in standby mode. Longer can be seen here relatively, because this lasts preferably too Time less than a second, while the query times are preferred in Move millisecond or microsecond range. As a result, the user falls energy-saving pulsed operation not at all.

In more preferred versions, extremely power-saving units are considered moving units used.

Another aspect of the invention is concerned with improving the Operational reliability. A particularly secure data protocol is proposed here.

Figures 1 and 2 show views of a powered building or Enclosure closure device using the example of a sectional door 2 with a Drive device in the form of a door drive 14 - here a wave door drive is shown -. The door drive 14 is controlled by a control device in the form of a Door operator control 15 controlled which also controls the movement of the powered wing the building closure, here the door leaf 3 is monitored. The Gate drive control 15 has a first fixed electrotechnical unit, mainly formed by a main control 13 arranged on the wall next to the gate opening, and a movable second electrotechnical unit which is attached to the door leaf 3 and for control, supply, evaluation, monitoring or for forming on the Door leaf 3 is used for detecting devices. The second electrotechnical Unity is mainly through a control and attached to the door leaf Evaluation circuit 16 formed for a closing edge safety device.

When considering electrotechnical units or components on the door leaf 3 To operate (sectional door, roller door, up-and-over door, up-and-over door, etc.) always exists again the problem of feeding these units, components or their electrical or electronic components. Either there are so-called here today Spiral cables or supply systems - similar to trailing cables or Supply via pantograph systems with sliding contacts - possible.

In contrast, the sectional door 2 shown here has an energy converter device for Converting or non-electrical energy applied to the door leaf 3 into electrical Energy provided for infeed. In one embodiment, this is a generator 1 operated small motor, for example stepper motor, which on the door leaf 3 of the Sectional gate 2 is attached to the lowest roller 4. When moving the Door leaf 3 rotates the roller 4 and generates electrical energy in the generator 1. Furthermore, is located in a control housing 5 attached to the door leaf 3 Control and evaluation circuit 16 with a supply device 6 to drive off the door drive 14 has a closing edge safety device 7 with an optosensor 8 with voltage to supply.

In the embodiment shown, there is also a further energy converter device realized via a small solar panel 9, which is on the outside or in Housing cover of the control housing 5 is housed. One or both of the energy converter devices 1, 9 is supplied by an electrical energy Energy storage device, here with Goldcaps 10, these are particularly powerful Capacitors, stored. Alternatively or additionally, the Energy storage device one or more accumulator (s) and / or battery (s) (not shown). So there is a possibility that - even if the Closing edge safety device 7 is actuated via radio 11 before the door leaf 3 starts to move Signal is given to an evaluation device 12 of the main controller 13 and the Main control 13 does not even give the command to the door drive 14 to start.

If the door leaf 3 now moves with a clear light path, the energy from the lower one Roller 4 and the attached or integrated generator 1 on the gold caps 10 and / or transmit the at least one accumulator and there with each opening and Downward travel buffered accordingly. So it is possible without an annoying direct Connection between the door frame 15 or the building / masonry 16 and the traversed door leaf 3 to work. This goes without saying on all types of gates or other building or enclosure closings are transferable.

The communication between the first and the second electrotechnical unit 13, 16 takes place via a wireless communication device. This is formed by a wireless transceiver system 30, which communicates here via radio 11. For this has the first electrotechnical unit, that is to say the fixed main control 13 a first receiver 18. The first receiver 18 is for receiving Command signals from a handheld transmitter, not shown, with which the sectional door 2 can be opened and / or closed remotely, and for receiving Signals from the control and evaluation circuit 16 designed. To the main control 13 a first transmitter 19 is also connected in order to transmit control or interrogation signals to the Control and evaluation circuit 16 to send.

The moving control and evaluation circuit 16 is connected to one on the door leaf 3 attached second transceiver 20 with a second receiver 21 and one second transmitter 22 connected. The second receiver 21 receives the through the first transmitter 19 sent control and query signals. The second transmitter could also be designed to receive command signals from the handheld transmitter. The second Transmitter 22 sends signals to the main controller 13 to pass this at least one display the detection devices detected state. The second transmitter 22 is used especially to send an OK signal if none of the control and Evaluation circuit connected sensors detects a state in which a Gate movement is not allowed. Additionally or alternatively, the second transmitter 22 could Detecting such a condition also includes a stop signal to the main controller 13 sent.

The transmitter / receiver system 17 is designed at least in two channels. The first Channel transmits an activating door movement signal, e.g. the command for the movement "gate open" or "gate closed". The second channel is a closed circuit assigned. In a closed circuit on the door leaf 3 there are different ones Detection devices that record conditions that occur before the start of a Door leaf movement must be present, connected in series. Is one of the If the conditions are not met, the closed circuit is interrupted. The one here Embodiment sends the OK signal only when the closed circuit is closed. The Main controller 13 only performs a door movement if and as long as it does OK signal received. If the reception of the OK signal is interrupted, the stops Main control 13 the motor 23 of the door drive 14 and / or reverses it. Such Detection devices can, in addition to the optosensor 8, the closing edge safety device 7 e.g. also be a wicket door contact (not shown), which indicates the closed state indicates a wicket door (not shown) in door leaf 3.

In the preferred embodiment here, which is a remote control via hand transmitter enabled, the first receiver also has a third channel for receiving Control commands from the handheld transmitter, is at least three channels.

The electrotechnical components mounted on the door leaf 3 can be moved switch between an idle state and an active state. By doing If possible, all electrical consumers are switched off in the idle state. Except here is the second receiver 21, which is ready to receive activating signals. During the idle state, the solar panel 9 also delivers the corresponding Energy radiation energy contained in the Goldcaps 10 and / or accumulators is saved. Only minimal electricity is therefore consumed in the idle state; at Appropriate irradiation gives a positive energy balance on average. For example the current consumption of the control and evaluation circuit 16 in the idle state is in the µA range. This is realized by an energy-optimized microcontroller that is programmed accordingly to form the control and evaluation circuit 16.

When the second receiver 21 is in the idle state, a corresponding control signal the main controller 13 received, the control and evaluation circuit switches 16 from the idle state to the active state, supplies everyone Detection devices 7, 8 with energy and sends when the closed circuit is closed the OK signal. In one embodiment (without wicket door) this switching only takes place on receipt of a "gate closed" signal, but not on a "gate open" signal, since signals from the Closing edge safety is only interesting when the closing movement is in progress. On a signal from Main control 13 out, which indicates the end of the door movement, or timed after a time when gate movements are usually completed with the addition of a Safety margin, the control and evaluation circuit 16 turns on automatically again from the active state to the idle state.

The operation of the sectional door 2 shown in FIGS. 1 and 2 is as follows. When the door leaf 3 is at a standstill, the gold caps 10 and / or accumulators are through the solar panel 9 loaded, the control and evaluation circuit 16 and the same connected components (e.g. optosensor 8) are in the idle state second receiver 21 is on reception. If the hand transmitter is now operated, it will emitted signal "gate open" or "gate closed" by the first receiver 18 of the Door operator control 15 received. The main control 13 becomes active, sends via the first transmitter 19 a corresponding control signal "gate open" or "gate closed" for activation the movable or other remote electrical engineering units, in particular the control and evaluation circuit 16, and then continuously tests whether the OK signal is received. The control and evaluation circuit 16 becomes active, supplies the detection devices 7, 8 connected in series in the closed circuit Energy and emits the OK signal when the closed circuit is closed. Is fed this is due to the energy from the gold caps 10 and / or accumulators. Upon receipt of the OK signal, the main controller 13 drives the motor 23 and leaves it Carry out door movement. However, one of the detection devices 7, 8 detects one Unauthorized condition (examples: wicket door open, closing edge not secure), that is the Closed circuit interrupted, the control and evaluation circuit 16 does not give an OK signal aborts or immediately interrupts its transmission. That is why there is a gate movement not started at all, or it is stopped and / or if the OK signal disappears reverses. When the gate movement is performed, the roller is driven drives the generator 1. So this generates energy precisely when the tax and Evaluation circuit 16 is in the active state and thus has a higher energy requirement than in Has hibernation.

The activation signal activating the control and evaluation circuit 16 (above with "gate on "or" gate closed ") is here by the to the main controller 13th connected first transmitter 19 to the second receiver 21 of the tax and Evaluation circuit 16 sparked. This always happens before the main controller 13 initiates a door movement automatically or after receiving a corresponding command, e.g. e.g. if an operator for the command "gate open" or "gate closed" one of her assigned actuating device actuated. This can except one to the Main control 13 transmitting hand transmitter also with the main control 13 wired or otherwise (e.g. via Bluetooth technology, via monitoring systems etc.) connected switch - e.g. internal switch, code switch, Key switch, contact threshold, proximity switch, remote switch, etc. This is the first transmitter 19 is connected to a test output of the main control 13, which is intended to be connected to the connected safety devices before each door journey to test their function.

A specific exemplary circuit and / or software structure of a Monitoring device for such a door or the door operator is in the following explained in more detail.

1 Introduction Working principle

This structure shows a possibility of a door operator with one on the Door leaf-mounted closing edge security unit - as also explained above - connect wirelessly. Through a bidirectional radio connection, the transmit necessary signals. This in comparison to the direct wire connection Always higher susceptibility to interference signals should be preferred by a very safe Data log can be compensated for an unnoticed malfunction practically can be excluded.

Particular attention is paid to the self-sufficient power supply on the door leaf. Around To enable permanent operation, either electrical energy should be on the Door leaf are generated or at least the power requirement of the unit mounted there be kept low that the replacement (or charging) of an electrical Energy source in the intervals of the mechanical maintenance of the gate is sufficient. By doing Exemplary construction explained here was in addition to the selection more energy efficient Components especially through a software control for the pulsed operation of the Safety device (s) achieved a significant reduction in operating current. The Waiting power is a determining factor as with most Gate systems make the active state only about 1 percent of the time.

Arrangement of the functional units

A transponder (transceiver) is attached to both the door operator and the door leaf used to enable bidirectional communication. Between The transponder and gate operator or safety device becomes a simple microcontroller switched, especially to the timing and logical flow of data communication Taxes. The closing edge security unit is powered by a battery that is in turn charged by a solar cell. It can also be charged by someone special dynamo that generates a charging current when the door moves. The real one Closing edge security unit usually consists of a light barrier that e.g. in the Inside a rubber profile is attached to the closing edge of the door leaf. There are but also other sensors or detection devices for monitoring safety-related parameters directly conceivable on the door leaf, their signals via this described system are transferable.

2 circuit

The transponders are treated as closed units as follows are also commercially available under the name radio modem. As an interface to the microcontroller units are the transmit and receive signals (according to the RS-232 Standard: RxD and TxD), a signal for the detection of a carrier field and a Signal for activating an energy-saving standby mode relevant. For the Transponder in this application is in addition to good general radio technology Features specifically the ability crucial from standby very quickly to switch to receive mode (and back) to receive a signal from the Recognize the other party. For usable types, this time is less than 10 Milliseconds, especially around one millisecond or less. The Standby current consumption is preferably below 50 µA, e.g. at about 5 to 20 Microamperes. In reception mode, the current consumption can be higher, for example in Milliampere range such as less than 15 milliamperes. Also offers in this Application of "real" bidirectional operation Advantages over the (cheaper) quasi-bidirectional operation because of faster handshaking of the remote stations Operating time can be saved.

In Fig. 3 the drive-side stationary circuit structure is a block diagram played.

The microcontroller 30 on the door leaf unit should have a low Power consumption or have a power saving mode. There are therefore many 8 Bit standard controller on (4 bit data width would also be technically sufficient). The at In the test, the blocks used required single-digit currents during operation Milliampere range, e.g. about 3mA, in standby mode (with timer running) less than 500 Microamperes. In pulsed standby mode, the operating current was 700-900 Microamperes.

The usual, simple electrical signals for the testing ("Test SKS) and query (" SKS actuated ") of the closing edge safety device (SKS) used. Optionally, the signals of further door leaf side Safety devices 60 (see FIG. 4) such as the emergency button or the Status of a wicket door contact are transmitted via the radio modem 50.

The structure on the door leaf is somewhat more complex, as shown in FIG. 4. Next to the Microcontroller unit 32 and radio modem 52 exist in the exemplary construction also a rechargeable battery 70, a solar unit 80, a closing edge safety transmitter 90 and a closing edge safety receiver 92.

• zur Betriebsspannungsregelung einen diskreten Längsregler mit besonders geringem Querstromanteil
• Transistoren zum Ein- und Ausschalten von SKS-Sender 90 und -Empfänger 92.

The microcontroller unit 32 also contains the following simple circuit parts (not shown):

• a discrete series regulator with a particularly low cross-current component for operating voltage control
• Transistors for switching SKS transmitter 90 and receiver 92 on and off.

For the generation of the microcontroller clock signal, resonators are recommended because they i.d.R. faster and more reliable than crystals. The frequency constancy is for operation on the serial interface is usually sufficient. The frequency should be right low (e.g. 1 to 3 MHz) to keep the operating current low.

3 Software / sequence control

The software flow control is from the flow chart shown in FIG. 5 for self-explanatory for the specialist.

Different ASCIH are used for the identifiers shown in the diagram Characters that are sent continuously for a certain period of time. For security, three consecutive signs for equality are received checked and then evaluated.

Particular attention should be paid to the first state of the Door leaf control: here the microcontroller changes automatically e.g. every 30 Milliseconds in receive mode, and initially only checks whether the current Carrier frequency field strength is above a relevant threshold. Is not this the standby mode is reactivated immediately. This test process (polling) lasted only a few milliseconds in the structure described here, for example approximately 1 to 5 milliseconds.

The condition of the closing edge safety should be permanent during the gate movement be monitored. From a technical point of view, however, this is also a way of saving electricity pulsed operation possible if the corresponding cycle time is chosen small enough. Depending on the security standard to be used, this value can e.g. 500 milliseconds be.

All of the features and steps described above and shown in the drawings are can be combined with one another as required. The numerical values mentioned here are guidelines in in practice can deviate upwards and downwards.
