Description

The The invention relates to a control system which, in particular to drive gates.

devices the type in question are used to operate gates and doors, especially in the domestic and industrial sectors.

Out The prior art is a variety of generic devices known. Most plants are operated with 12 to 24 V. and supplied from the mains (110 to 240 V). The power consumption of this Controls are very high in stand-by mode (about 40-50 mA). As a result, such systems are limited in one off-grid Battery operation can be used. Furthermore, they are powered by 12-24 V voltage, Battery or solar powered systems known. Problematic with such Is that with decreasing battery voltage (e.g. by cold or operation) slows down the operating speed. Furthermore is a reliable check safety-relevant with decreasing battery voltage Functions during operation is no longer possible. While a movement is to be checked continuously, if an obstacle is touched (power cutoff), being in touch immediately a reversion of the movement must take place. This releasing an object is then no longer guaranteed.

outgoing From this prior art, it is the object of the present Invention, a control system for driving a gate and a door lock system provide, which allow a long and safe operation of the gate.

These Task is by a control or regulating system for driving a Tores with the features of claim 1 and a door or door closing system solved with the features of claim 5. Advantageous embodiments The invention are the subject of the dependent claims.

According to the invention, a control or regulating system is provided for driving a gate or a door, comprising
a power receiving unit configured to be connected to an electric power supply system,
an output signal unit which can be brought into electrical signal connection with at least one control device of a door or door drive,
a data processing unit in electrical communication with the power receiving unit and the output signal unit,
a control signal unit which is adapted to receive control signals for controlling the door drive and to supply the data processing unit, wherein
the data processing unit has an active state and a passive state, in which passive state to the control device of the door or door drive the electrical signal connection is interrupted, and in which active state an initiation or wake-up signal followed by a control signal received by the control signal unit the output signal unit of the control device of the door or door drive is supplied.

The Control system can be any existing gate controller without interference or changes upstream and thus reduces the power consumption of the entire Plant significantly down to a few mA. For the daily operation of the system the upstream control system remains almost transparent. Only for longer, open Tor, the response time of the gate control is increased insignificantly. The Control system allows It thus advantageously, by significantly reducing the stand-by power consumption, a gate control independently from public Mains power to operate on batteries or solar panels.

preferably, the control system has a voltage stabilization unit, which preferably between the energy absorption unit and the Data processing unit is interposed and which designed is a substantially constant and predeterminable electrical Supply signal to the output signal unit.

Of the integrated booster or the voltage stabilization unit is advantageously to a value between 26 to 32 V (depending on existing plant), which is then kept constant, adjustable and This guarantees a stable power supply of an optional in the control system integrated test electronics.

Preferably the control system has an electrical power receiving unit on, um - for example from a solar panel - electric Get energy and this the energy delivery system - for example a battery - supply.

A charging electronics integrated in the energy receiving unit expediently ensures safe charging of the batteries. It protects the battery from deep discharge and overcharging. Threatens a deep discharge, warning signals are generated during the opening and / or closing movement of the door by means of a feedback device, which preferably emits acoustic or optical signals output. In order not to destroy the batteries, protective switching means are advantageously provided to switch off the system below certain voltage limits.

Conveniently, The power receiving unit has means to protect against overcharging and / or deep discharge of the energy delivery system.

Especially is an integrated solar charge control with temperature-compensated overcharge and Deep discharge protection provided.

• – eine Datenverarbeitungseinheit, die mit der Energieaufnahmeeinheit und der Ausgangssignaleinheit in elektrischer Signalverbindung steht,
• – eine Steuersignaleinheit, die ausgelegt ist, Steuersignale zur Steuerung des Tor- bzw. Türantriebs zu empfangen und der Datenverarbeitungseinheit zuzuführen, wobei die Datenverarbeitungseinheit einen Aktivzustand und einen Passivzustand aufweist, bei welchem Passivzustand zu der Steuereinrichtung des Tor- bzw.

Furthermore, an inventive gate or door locking system, in particular for swivel or roller doors, provided, comprising
a gate or door drive with a control device for moving a gate between an open position and a closed position,
an electrical energy source,
a control system connected between the power source and the controller and having

• A power receiving unit which is in electrical connection with the electrical energy source,
• An output signal unit which is in electrical signal connection or can be brought at least with the control device of the door drive or door drive,
• A data processing unit in electrical communication with the power receiving unit and the output signal unit,

• – Der Booster bzw. die Spannungsstabilisierungseinheit wird ein- und die Spannung auf die Torsteuerung bzw. Steuereinrichtung durchgeschaltet
• – Eine definierte Pause lässt der Torsteuerung für ihre eigenen Initialisierungroutinen Zeit, da die Torsteuerung bis zu diesem Zeitpunkt einen Zustand der dem nach einem Netzausfall entspricht.
• – Das Steuer- bzw. Regelsystem generiert nach dieser Pause einen kurzen Impuls am Taster-Eingang der Torsteuerung. Wenn das Tor geschlossen war, wird es in die Offenstellung bewegt.
• – Mittels in dem Steuer- bzw. Regelsystem vorgesehenen Zeitsignalmitteln wird nach einer vorbestmmten bzw. vorbestimmbaren Zeitspanne der Booster und die Spannung an der Torsteuerung abgeschaltet. Infolgedessen wird die Anlage wieder in den Standby-Zustand vesetzt, außer ein erneuter Funk- oder Schalterimpuls setzt diese Zeit wieder zurück. In diesem Standby-Zustand sind vorteilhafterweise alle peripheren Module, außer dem Empfänger bzw. der Steuersignaleinheit und vorzugsweise vorgesehenen Eingängen für Taster oder andere Schaltmittel, abgeschaltet. Insbesondere ist die gesamte Torantriebseinheit inklusive Steuereinrichtung abgeschaltet, d.h. nicht mit Strom versorgt.
• – Wenn sich das Tor in der Offenstellung befindet, generiert das Steuer- bzw. Regelsystem einen zweiten, kurzen Impuls, damit das Tor anläuft (vgl. hierzu nachfolgenden Absatz). Dies ist gewünscht, da aus Sicherheitsgründen Torsteuerungen nach einem Stromausfall bei geöffnetem Tor einen zweiten Impuls erwarten, um den Torlauf bzw. eine Schließbewegung zu starten.

The operation of the control system will be described below by way of example. In standby mode, advantageously all peripheral modules except the receiver or control signal unit and preferably provided inputs for buttons or other switching means are turned off. If a control signal (eg radio signal) or probe pulse is supplied to the control or regulating system, the following program sequence preferably takes place.

• - The booster or the voltage stabilization unit is switched on and the voltage is switched through to the gate control or control device
• - A defined pause leaves the door control time for its own initialization routines, as the door control up to this point in time corresponds to a state after a power failure.
• - The control system generates a short pulse at the pushbutton input of the door control after this break. When the gate is closed, it is moved to the open position.
• By means of time control means provided in the control system, the booster and the voltage at the gate control are switched off after a predetermined or predeterminable period of time. As a result, the system is reset to standby, unless a new radio or switch pulse resets this time. In this standby state, advantageously all peripheral modules, except for the receiver or the control signal unit and preferably provided inputs for buttons or other switching means, are switched off. In particular, the entire door drive unit including control device is switched off, that is not supplied with power.
• - When the door is in the open position, the control system generates a second, short impulse to start the door (see paragraph below). This is desirable since, for safety reasons, gate controllers expect a second pulse after a power failure with the door open in order to start the door run or a closing movement.

A particularly advantageous feature of the control or regulating system is, without interfering with the door control or accessories such as limit switches, to detect whether a gate is closed or opened. After the first impulse, which would lead to immediate start-up with the door closed, the current flowing into the gate control is measured. However, it is not possible to tell from the strength of the flowing current alone whether the door drive is running or not. Even powered peripherals such as lamps and safety devices require a current that is about the same order of magnitude as the drive motor current. However, a running door drive generates a specific current pattern. The data processing unit of the control system is advantageously designed to detect and evaluate this pattern by means of digital signal analysis (discrete Fourier transformation) so that it can be determined on the basis of this signal analysis whether the door drive has started running after the first pulse or not. The data processing unit of the control system is further advantageously configured to perform this detection when an inverter is connected between the control system and the gate drive is switched (this inverter is only necessary with higher supply voltage up to 240 V drives). This is possible in the control system according to the invention, because the control system advantageously has a signal filer unit to filter out the signals caused by the inverter. If the drive has not started, then after a settable pause, a second pulse is applied to the button input of the gate control, which then starts the gate drive.
