BACKGROUND OF THE INVENTION

In the German utility control unit of various functions the microcontroller is a system through which the apparatus, the data input device and the data output device.

model no. G 9.307.326.7 is described by a door in which the degree of automation is ensured by a microcontroller. In this case, for example, diagnostic devices can be connected via a bus-connected interface

The electronic control device is also known from published international application WO 92/13 300. In this costly control unit, two independent control signals are provided based on one microprocessor-equipped unit which are fed to two motor units intended to move the door wings. This type of control makes it possible to control both door leaves completely independently.

Doors of this type are also recognizable from German Patent Specification No. 3,940,762, which particularly describes sliding door drives. The doors of these doors are driven by a motor, and an additional electronic control capable of self-checking can be connected to the standard door movement control activated by the program switch. This additional electronic control consists of a door security module which is connected on the one hand between the internal motion detector, the program switch and the limit switch and on the other hand between the standard control, the electromagnetic clutch and the indicating device.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the invention to substantially reduce the final cost of controlling and controlling a door by providing a configuration by which the number of control types of the various types of door is substantially controlled.

The invention according to the main features of the first claim utilizes a base unit which enables the processing of all the non-essential information for the control and / or control. regulation of connected doors. Such direct processed signals of the emergency key switch Thus, the control base unit may be sensors, program switch, trip, pulse sources, etc. the signal for controlling the connected motor coming from the base unit is directly supplied from this unit and by means of pulse sources, for example an incremental sensor, the door position or the direction of rotation of the motor is sensed. The base unit is therefore equipped with a software-based operation program so that all information that is essential for the safe operation of the door can be stored. This information can be read from the base unit via an external manipulator. In this case, however, it is not enough just to shoot, but also the possibility of changes over the programme- _t thus enabling seamless adaptation to different types of doors, respectively. changes in door running properties. However, the manipulator can also be used as a diagnostic port; it can be used to detect, and possibly to record, door parameters, such as, for example, running failures, motor currents. The manipulator also allows static evaluation of, for example, the load cycle or the time when the door is at rest. Communication between the manipulator and the base unit is ensured via the RS 485 interface. This type of interface allows for other types of door communication, for example through the home wiring, in addition to data acquisition and input, for example or closed.

The base module is further able to detect which drive motor is connected, which means that the base module can be used for various types of doors, such as sliding doors, trapdoors, hinged doors, revolving doors and others. Furthermore, it is possible to perform a motor current control in such a form that the pulses being fed from the base unit to the motor are quiescent with the data stored in the software memory. With any difference, the actuator is brought to a standstill.

The base module is also equipped with a system of connectors to which the bus system can be connected, resulting in a substantial reduction in the conductors. Various plug-in modules can be connected to the base unit via this connector system. In doing so, the base unit is able to automatically recognize which connected ones. Add-on modules The types of add-on modules can be equipped with different intelligence.

These measures can significantly reduce the set-up costs.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention is explained in more detail in the accompanying drawings by way of a schematically illustrated exemplary embodiment. Here it means:

Fig. 1 shows a base unit with attached additional modules, FIG. 2 shows a block diagram of the add-on module FIG. 3 shows a block diagram of the add-on module FIG. 4 shows a block diagram of the add-on module FIG. 5 is a block diagram of a data bus.

Examples

Various input units or sensors can be connected to the base unit 7, such as a program switch 1 via link 8, a sensor 2 via link 9, a code switch 3 via link 10, an emergency trip probe 4 via link 11. the door operation program selected for the base unit 7. The sensor 2 can be, for example, an infrared sensor or a radar signal. However, it is also possible to use a photosensor here. These sensors ensure the proper operation of the door leaves. By means of the code switch 3, for example, the door can be blocked for closing, or it can be restarted depending on the emergency stop probe 4 being activated in case of danger. All of this input information is processed in the base unit 7 into a program not marked here. . The result of this information is transferred via the link 13 to the motor 6, which moves the door wings according to the respective program. At the same time, the direction of rotation of the motor 6 and the position of the door are measured by means of a pulse source 5 via a connection 14. These data are then transferred back to the base unit 7 via the link 12.

Since the base unit 7 is also able to recognize the type of motor connected, the internal resistance of the motor is measured by means of the current control 51, which result is transmitted back to the base unit 7 via the link 52. The base unit 7 compares this value with the program values. stored within its memory. If there is an unacceptable difference between the curve stored in the memory (setpoint) of the motor and the previously determined values (actual value), the base unit 7 blocks the further motor movement. Only after the error has been corrected should the door move again again after the restart.

A manipulator 15 can also be connected to the base unit 7 via an interface 16. For example, an RS 485 interface can be used as an interface 16. Via the manipulator 15 in conjunction with the interface 16 data of the base unit 7 can be read. located within the base unit Z By means of the manipulator 15, the behavior of the door can be controlled, not only in the current state, vein as well as in the past, including data recording and parameters. Thus, this interface 16 allows the connection and thus also communication with the home control device or alarm device installed in the building. As a result, the door can be closed by means of pulses not only from one location, for example in the event of a fire, or if they are installed in the exit route, they can be safely opened.

The base unit 7 comprises a connector system into which a bus 17 is inserted, which allows the connection of various add-on modules 18, 20, 22. These add-on modules 18, 20, 22 can be freely connected via the bus 17 via connectors 19, 21, 23. base unit 7. Although the base unit 7 is capable of automatically controlling and controlling the operation of the door itself as described above, due to the various door systems used today mainly in shops, it is often unnecessary for it to be available and to process more information as the base unit 7 is able to process. The idea of a base unit is usually such that when operating a simple door, it is equipped with the necessary intelligence, but at the same time is able, through retrofitting additional modules to build a system with a higher intelligence, which can be used for doors in reliably less secure areas, or emergency exits.

For this reason, the connection modules 18, 20, 22 and possibly also other modules are connected to the base unit 7. Therefore, in order to allow the respective communication between the base unit 7 and the connected additional module, this communication is ensured via the bus system 17. At the same time, as will be explained below, it is also envisaged to backup the control via information, either in the add-on modules 18, 20, 22 or also in the base unit 7, which at the same time represents a higher level of security.

In FIG. 2 shows an additional module 18 which is connected to the bus 17 via a connector 19. Thus, for example, a sensor 24 can be connected to the additional module 18 via a connection 25. This sensor 24 can be either a photosensor or a radar detector. The add-on module 18 can also be supplied with non-essential energy by means of an emergency power supply 26 in the form of an accumulator connected via a connection 27. A separate program switch 28 can also be connected to the add-on module 18. a further sensor 30 is connected by means of a joint 31. If it concerns the connection of the add-on module 18 to another type of door, it is possible to install an interlocking unit 32 inside the add-on module 18, whose reporting is transferred to the add-on module 18 via a link 33.

In FIG. 3, a further add-on module 20 is shown in the block diagram, which in addition to the information carriers shown in the embodiment of FIG. 2, which is the sensor 24, the emergency power supply 26, the program switch 48, the sensor 30 and the locking unit 32, contain further, non-essential information for the operation of the special door. Such information may, for example, be a door edge safety switch 34 connected to the add-on module 20 via a connection 65. In this case, it is primarily a sliding door which can thus be designed for a particular field of application. Additional information 36 could be included here, for example, for pharmacy doors that are delivered to the add-on module via link 38

20. Similarly, additional information 37, for example, for a gate used in a lock chamber, may be fed to the add-on module via the link 39. To the add-on module 20, a door parameter adaptation unit 42 can also be connected via a connection, which can be adjusted or changed, for example by means of a potentiometer, the door speed or set the door opening time delay. Since this is an add-on module with a higher intelligence, the display unit 44 is also envisaged as an indicator of the current status or door operation errors. The display can be used simultaneously for diagnostic purposes.

In the block diagram of FIG. 4, in addition to the functions of the add-on module 20 described above, there are shown other functions applied to doors used, for example, in emergency exit and emergency exit locations. Here, for example, the door contact 46 can report 80% opening of the door via the joint 47. To further enhance security, a control system 48 is used, which, for example, in conjunction with a time guard controls the microprocessor system. If the door is to be used in the emergency exits, the auxiliary drive 49 can be activated via the joint 50.

As can be seen from the description of the above block diagrams, the base unit is always connected to a bus system, to which additional modules are then connected. This creates a modular system or backup system, which offers the possibility of connection to different types of doors.

As shown in FIG. 5, in addition to the possibility of arbitrarily connecting the various add-on modules 18, 20 and 22 to the base unit 7 via a connector system, there is the possibility of simultaneously connecting multiple add-on modules to the base unit 7. In this case a sufficient connector system for this purpose. The individual connectors can be provided with coding which simultaneously ensures correct signal processing in the base unit 7. Due to their function, the base unit 7 is then able to perform the signal processing of the respective add-on module.

In order to perform the typing of universal compact door control systems, the individual add-on modules 18 and 22 may be coupled together with the base unit 7 by a so-called VG connector. These VG connectors can be made straight or curved, but are preferably part of the base unit 7. In this way, it is possible to connect the various add-on modules 18, 20 22 to the base unit 7, taking into account the special requirements and / or requirements. needs of individual control functions.

The transmission of signals between the individual add-on modules 18, 20, 22 and the base unit 7 is performed by the individual conductors via a bidirectional data bus 53. In this data bus 53, data is designated as binary information sequentially transmitted to one or more add-on modules 18, 20, 22 The same applies to data transmission between the individual add-on modules 18, 20, 22. The corresponding data in the basic unit and the add-on modules 18, 20 or 22 are always induced in parallel. This method of transmission thus allows a slightly shifted function of information, thereby allowing the information to be transmitted in succession. This information is therefore delivered to the individual modules for use as concurrent information, where it can be further processed.

By means of the data bus 53, add-on modules 18, 20, 22 can be provided with different degrees of intelligence, as described in the various embodiments. With this method, the hardware of the connector connections is desirable and the principle of data transmission for connecting different door systems cannot be changed. The invention thus represents an enrichment in the field of door technology, since the basic unit and the add-on modules create a concept which can be adapted to all technically controllable or regulated door drives.
