Abstract

The invention relates to an electromechanical drive unit for operating a gate, a door, in particular a garage door or the like, in which a control and regulating unit is completely de-energized in the standby mode, corresponding components that are not required at this point in time. Isolation circuits that work electronically or with contacts are used for this purpose.

Description

The invention relates to a drive unit for automatically operating a door, a door, in particular a garage door or the like.

A generic drive for a gate, a door, in particular a garage door or the like is from the DE 10 2005 039 533 A1 refer to. In this case, a drive unit is operated using a drive with a drive wheel, a clutch and a position detection device, which includes a data processing unit in which various variable sequence programs are stored.

A drive unit for a door leaf, which is equipped with a transformer having a primary winding with at least two individual windings, which are connected in series outside the operating time, gives the DE 43 16 645 C2 again. Due to the series connection, the copper losses during idling are to be reduced by the series connection.

The DE 20 2005 000 349 U1 discloses a lighting device in which the commonly used light bulbs have been replaced by LEDs.

In the DE 195 12 204 A1 a power supply device for at least temporarily operated on a supply network PC's with monitor or similar, used for data processing and telecommunications equipment used. The power supply has at least one power supply, which, starting from the mains input voltage, provides at least one input of the supply voltages required in the PC at the output of the power supply in such a way that at least one control and monitoring unit is present which monitors and transports the data traffic to the personal computer an initial connection establishment and / or onset of data traffic generates a signal for activating the power supply for the activation of at least the PC for the data traffic.

Today's energy-saving measures are required due to the lack of availability of energy forms or energy carriers. In this case, a lack of availability of energy, for example, due to the capacity of the grid connection. Thus, high energy-related operating costs are ultimately the main argument for many energy-saving measures. It can be such an energy provided by waiving certain benefits can be reduced.

It is therefore an object of the present invention, a drive unit of a door, a door, in particular a garage door or the like in such a way that an environmentally sound energy balance over known drive units for gates, doors, especially garage doors or the like results.

The object of the invention is solved by the features of patent claim 1. The dependent claims provide a further embodiment of the inventive concept again.

For example, a reduction in energy requirements can be achieved by eliminating certain services that are not constantly needed, for example for certain additional functions on a gate, a door, in particular a garage door or the like, which are needed only during the operation of the door leaf or the door, bring about a reduction.

Thus, for example, essentially all components of a drive unit which have only a limited use for the passage of the door, the door, in particular the garage door or the like, can be disconnected from the power supply during the remaining time. These include, for example, a position detection unit, a light barrier unit, pulse generator, door contacts, in particular wicket door contacts and any type of sensors and of course the mains transformer.

Operational readiness means that the gate, the door or the like can be put into operation at any time, for example by the command of a radio remote control, via the drive unit. For example, such an operation may be referred to as standby, but with a multiple number of devices, standby operation also requires power even though the devices are apparently off. This results in no-load losses, which bring energy consumption in the waiting area. In such states, the utility function is temporarily disabled, but it can be activated again at any time without a long wait.

In the present invention, it is irrelevant whether the operational readiness is associated with a total elimination of the supply energy or whether only a part of the components not required for the original operation are de-energized. Thus, it is possible that all not in the open or closed position of the door, the door, in particular the garage door or the like necessary components are switched completely de-energized or it is also possible, only a part of these, not exhaustively referred to components de-energized switch or reduce their power consumption. In the individual case, this must be weighed in particular by the shutdown or reduction of the Power supply no safety-related components are switched off. This operation with regard to safety must be ensured at all times. Thus, it goes without saying that, for example, the radio receiver within the drive unit constantly, albeit within a standby mode, must be activated, in which case certain functions can possibly be reduced and thus contributes to a reduction in power consumption. Likewise, it is necessary that a part of the control unit is constantly energized so that when a radio signal from a remote control of the receiver contained this information can be forwarded immediately directly to the control unit, so that the connected door, the door, especially the Garage door or the like, can be closed or opened according to the desired function; However, a reduction in power consumption for certain modules can also be performed here, so that a part of the modules or components are placed in a so-called sleep mode in which they can do without a power supply or a significant reduction of the power supply is performed.

For a safety-relevant operation, it is necessary, for example, that the pulse generator should be constantly supplied with the supply voltage in a standby mode, as in a subsequent operation from this position out the exact position of the door or door leaf for the further function of the door, the door , In particular, the garage door or the like is determined.

Even a burglar alarm system can not be completely disconnected from the power supply.

To supply a portion of the non-operational inoperative components without power or with a reduced power supply, this can be controlled by the control unit by means of various stored sequence programs accordingly. This can be done directly after an opening or closing process or it is also possible that this shutdown or reduction takes place with a time delay. A time-delayed shutdown can be provided, for example, in particular for the lighting.

In order to be able to execute a command which originates from the control and regulation unit to the individual components by means of a program step, it is necessary to execute corresponding switching functions via the programs in the control unit. For this purpose, it is possible, for example, to use isolating circuits or the like which interrupt a power supply of the corresponding components in which they are connected between the power supply lines. By this intermediate circuit, the separation circuit can be selectively controlled by the control and regulation unit according to selected and stored flow programs, so that a timely shutdown or reduction of the power supply is possible.

For such separation options, the control unit can, for example, transmit coded switching commands that execute the switching process with matching control codes and also report back the switching state to the control and regulation unit. Thus, for example, an automatic power switch for energy-saving standby mode can be performed in the form that at rest, this power switch requires no auxiliary power and has stored for activation the necessary energy in a maintenance-free electronic energy storage.

In a further preferred embodiment, it is possible that the drive unit with the control and regulating unit and a lying on a power supply via a switch power supply for supplying functional units to be controlled and the control unit, via lines to a device to a external data network can be connected via the control signals, in particular a call signal to be sent to the control unit to perform a data transfer and thus movement of the door, the door, in particular the garage door or the like. In such a system, a switch in the form of a release agent or a disconnect circuit separates the drive unit in retirement on the primary side of the power supply during operation of the operational readiness. Only by the application of a call signal or even the signal of a radio remote control, the power supply to the power supply can be maintained or switched again.

It is also possible according to the invention that a corresponding program of the control unit for the disconnecting circuits is activated by the delivery of an instruction of the receiver.

Furthermore, it is also possible according to the invention that successively, d. H. corresponding consumers of the drive unit are switched off by the control and regulation unit at a time interval, as well as in a preferred embodiment the power supply unit as such. It is understood that this is only switched off for safety reasons, when all other components are already de-energized.

Through the use of a separation circuit, it is possible to use release agents that are contact-based or non-contact. Suitable relays or the like or electronic circuits are suitable for this purpose.

It is understood that in such a design of a drive unit, this is also intrinsically safe.

Since stored in corresponding memories or in a microcontroller program or if there are several programs, they always have the safety in mind, it is always ensured that in the execution of individual program steps each monitoring is interposed. This measure ensures that when a component is switched on or also switched off, the safety potential prior to energy saving always has priority.

Depending on the design of the connected door of a drive unit, it is possible to provide a wide variety of programs for operational readiness.

The invention will be explained in more detail with reference to various, schematically illustrated in the figures, possible embodiments.

In the 1 is a schematic block diagram of a first preferred embodiment of a drive unit 110 shown. For the sake of clarity, only the components or connections that are essentially necessary for the understanding of the present invention are shown in this illustration.

Via a network connection 115 and a power transformer 130 becomes the drive unit 110 over her power supply 101 supplied with the appropriate energy. With the power supply 101 they can be power supplies of any type. The power supply 101 powered by an electrical connection 116 directly a receiver 102 for the use of a radio remote control. Likewise is via an electrical connection 117 directly a control unit 103 next to a pulse generator 107 , via an electrical connection 118 to the power supply 101 connected. It turns out that in this embodiment only the receiver 102 , the control unit 103 and the pulse generator 107 directly to the power supply of the power supply 101 issue. By this preferred embodiment it is clear that these components should not be switched in the standby mode de-energized or completely de-energized. In addition to the components described above includes the drive unit 110 for example, another position detection 105 that have the electrical connections 123 and 124 is connected to electrical energy when one between the electrical connection 123 and 124 located isolation circuit 104 the corresponding voltage to the position detection 105 forwards. The isolation circuit 104 is via a switched control connection 129 with the control unit 103 connected and is functionally an activation or blocking of the power supply through the isolation circuit 110 to the position detection 105 enable. The position detection 105 is via appropriate electrical connections 125 with a drive motor 114 , outside the drive unit 110 can be connected.

From the control unit 103 go further according to the 1 further tax connections 126 . 127 and 128 from. These tax connections 126 . 127 and 128 each go to isolation circuits 112 . 106 and 113 ,

The isolation circuit 112 is for example between the electrical connection 119 that by the power supply 101 out to the isolation circuit 112 leads, switched, so that the continuing electrical connection 120 for example, a light barrier 108 only then switched through and thus supplied with electrical energy, if this via the control connection 126 from the control unit 103 , according to a sequence program, is desired. On the most diverse Sequence programs will be discussed below in the procedures to be described.

The electrical connection 119 leads in the embodiment of 1 to the isolation circuit 106 and the isolation circuit 113 and the isolation circuit 112 , These disconnectors too 106 . 112 and 113 be about the control connections 129 and 128 the control unit 103 controlled according to appropriate programs. At the output of the isolation circuit 106 is a connection 121 in the desired case of switching the supply voltage through the isolation circuit 106 , For example, a door contact, not shown, which may also be designed as a wicket door contact, continued.

The same applies to the isolating circuit 113 that the power supply after clearing the control connection 128 over the switched connection 122 to a, unspecified sensor 111 , continues.

The division described above in this preferred embodiment shows that the presence of multiple isolation circuits 104 . 106 . 112 and 113 , the number of which is not limited, all of them simultaneously or separately by the control unit 103 can be turned on or locked. It is because of this separate driving of the isolating circuits 104 . 106 . 112 . 113 Of course, also possible that during the run, ie the movement of the door, the door, the garage door or the like, only at a certain time, the corresponding consumers are supplied with voltage and are switched to the rest of the time de-energized.

To activate the power supply, for example, a switch or a radio signal of the remote control to the receiver 102 be used, and then the control unit 103 the disconnecting circuits 104 . 106 . 112 . 113 free again, so that the power supply for the components 105 . 107 . 108 . 109 and 111 is restored.

In the preferred embodiment of 2 are opposite the 1 more isolators have been introduced. So it is possible in this embodiment that, for example, by a separation circuit 135 , the electrical connection 115 the mains connection to the mains transformer 130 through a disconnecting circuit 135 can be switched off. By such a circuit would all components of the drive unit 110 can be switched off. The isolation circuit 135 separates the mains transformer on the primary side 130 from the power supply. Such a measure ensures that no idling losses of the power supply 101 available. Furthermore, by such a measure, the entire operation of the drive unit 110 be brought to a standstill. For example, by a call signal of a radio hand transmitter, which is not shown in this case, to the receiver 102 would an activation and thus an activation of the separation circuit 135 cause. The low energy required for the standby mode of the receiver 102 is required for activation can be provided by appropriate electrical storage, for example in the form of capacitors.

According to a preferred embodiment, the isolation circuit 135 via the control unit 103 over the electrical connection 136 to be activated.

In a further preferred embodiment, according to the 2 the drive motor 114 delayed, this may become necessary when the entire drive unit 110 previously stayed within a standby. The individual commands and program steps to be performed will be discussed below. The isolation circuit 137 is through an electrical connection 138 with the control unit 103 connected. It turns out that, for example, due to the compounds shown, the isolation circuits 135 . 104 . 136 . 132 . 112 . 106 and 113 all selectively via the associated control lines by means of the control unit 103 can be controlled. This is of particular interest that so already at an early stage, for example, after closing the door certain components that depend on the power supply, can be switched off and, for example, a lighting device 131 is switched off at a later time, after the expiry of a certain retention period. The lighting device 131 is via an electrical connection 133 with a disconnecting circuit 132 connected, one-sided to the electrical connection 119 is connected and via an electrical connection 134 is switched.

In a further preferred embodiment of the 2a is it possible for the power adapter 101 not the mains transformer 130 includes and directly from the mains connection 115 via an electrical connection 139 is at the mains voltage. In such a case, the power supply could 101 For example, be a switching power supply or the like and the secondary voltage of the power transformer 130 For example, it is preferable to supply the drive motor 114 and the light 131 used. In such an embodiment, the power supply would 101 never be de-energized because of this important components are supplied with electrical energy, but at the same time only one require low energy consumption in the operational readiness. So in this version is right in front of the mains transformer 130 the isolation circuit 135 switched, which also in this case over the control 136 from the control unit 103 after a program or else by limit switch when the drive motor is at a standstill 114 a shutdown of the mains transformer 130 performs. By the current-less connection of the mains transformer 130 their idle power is eliminated.

This preferred embodiment shows that in addition to a total shutdown of components and a supply of components or modules continue via the network connection 115 is guaranteed.

The 3 shows the possible course of a program or several program steps by the control unit 103 be executed. Based on a readiness for operation 18 , which is a sleep mode of the drive unit 110 represents is due to a start command 19 , an activation of the recipient 102 performed. The recipient 102 receives a radio code 20 from one to the drive unit 110 belonging, not shown wireless connection has been discontinued. It is understood that in addition to the radio connection via a stationary switch, a corresponding start command can be issued. After checking the activation 21 The radio code is either in a non-existent plausibility lock in the form of a stop command 22 executed and the program activates the drive unit 110 not further. However, the review is 21 of the radio code is positive, then becomes a command 23 for energy activation of the microcontroller of the drive unit 110 passed. In this step, the microcontroller is awakened, for example via an external interrapt quasi, which is programmatically to a program step 25 leads, which is an activation of the transformer 130 entails. Time is the settling of the power supply 101 about a command 26 monitors, and the output of the power supply 101 is only released when the required supply voltage for the drive unit 110 in the necessary quality.

After the release the vibration of the power supply 26 is done, at the same time components that are necessary for safety, can be supplied with electrical energy. These are, for example, program steps for the instruction of switching on 27 an encoder or switch on 29 a photocell 108 or a command 28 to a sensor, for example temperature monitoring. For all the components after the transient of the power supply 101 be supplied with electrical energy, a time window is again provided and thus a monitoring of the transient 30 performed. The signals emitted from it are called command 31 forwarded to a monitoring. If this signal is not correct, then a monitoring error 33 reported a renewed settling of the power supply 101 causes or a waiting time in the form of a command 34 then re-activating the commands 27 . 28 . 29 perform. After checking the transient signals using the monitoring 32 can be performed automatically, the command 36 for switching on the lights 131 and the command 37 for switching on the drive motor 114 over the electrical connection 138 to the isolation circuit 137 are given. The isolation circuit 137 thus gives the according to the electrical connection 125 applied signal continues, leaving a command 38 "Start engine" can be executed. This has the consequence that the connected drive motor 114 the door, the door, in particular the garage door or the like opens, this means that a feedback 1 , Drive drives' is present. The drive motor 114 is now energized until it has reached the full open position of the door, the door, in particular the garage door or the like due to the stored position.

In the block diagram of 4 the program steps are explained in detail, resulting from the driving operation 1 both result in reaching the end positions in the open position as in the closed position. The open position and the delivery contain different positions, but are by a command 2 , namely reaching the end positions, to the control unit 103 reported. This causes a command 3 'Engine stop' to the control unit 103 is given. After expiry of an adjustable pause time 4 be first commands 14 to switch off the light barrier 108 , certain sensors 111 and off 7 of the encoder. This execution of the corresponding commands is also via feedback 11 . 12 and 13 to the control unit 103 reported in a program step 9 turns off the controller. The shutdown 9 but the controller is only then carried out, albeit with a time lag over the command 15 the light switch-off 8th has been carried out. Again, there is a corresponding feedback 10 that reports that the light 131 has been turned off. This feedback also goes to the command 9 , After all the components to be monitored about their feedback 10 . 11 . 12 . 13 The proper shutdown will be reported by a command 16 from the command 9 'Switch off controller' off 17 of the transformer 130 given. This is the command 'readiness' 18 again generated.

The quasi-awakening within the operational readiness 18 sunken drive unit 110 runs according to the program steps of 3 from.

The method steps described above show that both a selective and a general shutdown of the control unit 103 or the entire drive unit 110 is possible. This depends on the individual case of the drive unit used 110 and their field of application.

In order to be able to perform a proper switching off or also switching on again the most different components, the disconnecting circuits 104 . 106 . 112 . 113 . 132 . 135 and 137 necessary. It should be noted that this version of the individual isolators is not exhaustive.

In the 5 is in a first preferred embodiment of a separation circuit 104 . 106 . 112 . 113 . 132 , a circuit breaker 42 represented by a ground connection 41 has and control connections 126 . 127 . 128 . 134 . 136 or 138 is controlled. The control is by means of the control unit 103 carried out. An exit 44 of the circuit breaker 42 goes to the consumer to be disconnected from the power supply 108 . 109 . 111 . 114 . 131 . 105 . 130 , Here are the consumers 108 . 109 . 111 . 114 . 105 . 131 . 130 one-sided over a connection 119 or 129 with the power supply 101 connected. Through the circuit breaker 42 is going to consumers 108 . 109 . 111 . 114 . 105 . 131 . 130 deprived of the ground connection. Such a circuit breaker 42 can be designed as an integrated circuit or as a thyristor or as a circuit breaker.

In a further preferred embodiment of a separation circuit according to the 6 this is by means of a transistor 40 executed. A collector 45 of the transistor 40 is at one of the consumers 105 . 108 . 109 . 111 . 114 . 130 or 131 connected. The consumer 105 . 108 . 109 . 111 . 114 . 130 or 131 is in this embodiment also again on one side of the power supply 101 connected. The emitter of the transistor 40 is due to mass 41 , The base of the transistor 41 is via a resistor 39 and the control connections 126 . 127 . 128 . 134 . 136 or 138 with the control unit 103 connected.

The 8th shows a disconnecting circuit 104 . 106 . 112 . 113 . 132 . 135 and 137 between the power supply 101 the connected consumer 105 . 108 . 109 . 111 . 114 . 130 or 131 as a switching contact 43 is inserted. The switching contact 43 separates or connects the consumer 105 . 108 . 109 . 111 . 114 . 130 or 131 with the supply voltage of the power supply, which is one-sided with the ground 41 are connected. Such a switching contact 43 may for example be part of a relay, a reed contact or the like.

In the 7 is opposite the 5 the integration of the separation circuit 104 . 106 . 112 . 113 . 132 . 135 , and 137 conversely, it is in front of the consumer 105 . 108 . 109 . 111 . 114 . 130 or 131 used, in which case the circuit breaker 104 . 106 . 112 . 113 . 132 . 135 , and 137 one-sided to mass 41 lies and the consumer 105 . 108 . 109 . 111 . 114 . 130 or 131 with the power supply 101 connected is.
