Definitions

• the invention relates to an operating method for operating a revolving door, in which the drive motor does not apply the entire force for the rotational movement of the rotating leaves. Rather, it provides a support mode which realizes this operating method by means of a microprocessor control / regulation in conjunction with a drive unit. Since the drive motor does not supply the entire drive force, a further part of the required force must be applied by at least one person who wants to pass the revolving door. Through constant contact with at least one of the rotary blades, a force is exerted on this, which is detected and passed on to the microprocessor control / regulation.
• the microprocessor control is able to calculate a value for the power support of the drive motor according to a program that is always below the total value of the required force.
• any safety electronics usually required such as Sensors, light barriers, radar detectors etc. can be dispensed with for safe operation.
• the rotating revolving wing of the revolving door which is mounted in the middle, is located within two drum walls, which are usually interrupted by two diametrically opposed entrances and exits.
• German patent specification 39 34 662 discloses a revolving door which is provided with a safety circuit and an electronic brake mass which can be braked and locked.
• a programmable controller equipped with a microprocessor controls the sequence of the door and also ensures that the safety sensors and devices guarantee that the door runs smoothly.
• a revolving door which is regulated or controlled by a data processing unit, all functions including the control and the microprocessor being monitored internally, can be found in German patent DE 42 07 705. Thanks to the almost complete This revolving door is characterized by a digitally automated control process, particularly with a view to optimizing operational safety for the user.
• these can be switch mats, sensor strips, light curtains, infrared and radar detectors and light barriers. All of these sensors in themselves allow such a revolving door to be operated safely.
• a door is quasi disturbed in its actual running behavior, i.e.
• Such a revolving door often comes to an emergency stop, which in turn usually requires manual opening by such trained personnel.
• the cost situation of an automated revolving door compared to a manually operated revolving door without sensors must also be taken into account.
• the object of the invention is to provide an operating method for the control or regulation for a motor-driven revolving door, which however allows that no other usual safety sensors or safety devices, as described above, for the user for the operation of such revolving door available. Nevertheless, this ca russellg can also be walked on by disabled people or the elderly without great physical exertion.
• the object of the invention is achieved in that the revolving door driven by a microprocessor control / regulation virtually only runs in a support mode or servo mode by a drive unit in connection with a drive motor. Since it is only a support of the drive motor, at least one of the persons who want to pass the revolving door must exert an additional force on one of the rotating leaves. This force applied in the direction of movement of the rotating wing is at the same time the indicator that a person is walking through the revolving door.
• the microprocessor control / regulation recognizes that there is a rotational speed of the vanes here and in turn now ensures that the electromotive drive provides support for this rotational speed.
• This support is to be understood in such a way that the measured peripheral speed of the rotary wing or the acceleration force of the rotary wing, caused by the manual force (actuating force) of the person, the microprocessor control / regulation calculates a support speed, the amount of which is less than the peripheral speed of the rotating wing.
• the total speed of the rotary wing is composed of the speed of support by the drive motor and the difference to the manual force and thus the speed of the rotary wing.
• the support of the drive motor requires control by a sequence program, which in turn requires information about the speed of rotation of the rotating blades and the motor current. For this reason, the speed of rotation must be measured, such as with an incremental encoder or a tachometer or other measurement options. The result is then forwarded to the microprocessor control / regulation, where it is processed in accordance with the existing sequence program.
• the peripheral speed of the rotating blades is used for the evaluation of the driving curve, the measured motor current being an indicator of the control behavior of the motor.
• the size of the support provided by the drive motor can be specified, for example, as a percentage of the actual end value of the current speed. This amount of support is adjustable, so that it is possible to regulate or control the revolving door according to its various places of use, as is necessary, for example, for doors of different sizes.
• Figure 1 Top view of revolving door
• a schematically represented revolving door is shown in plan view in FIG.
• the rotatably mounted rotating blades 10, 11, 12 and 13 are located between two drum walls 2 and are attached to a center point.
• the rotating blades 10, 11, 12 and 13 are connected to the drive motor 14 via a drive wheel 36.
• pressure In order to set the rotary blades 10, 11, 12 or 13 in motion, pressure must be exerted on at least one of these blades by at least one person. Since the pressure or the force is proportional to the speed, for the sake of simplicity only reference is made to the speed in the following exemplary embodiment.
• the increasing peripheral speed of the rotary blades 10, 11, 12 and 13 follows a quasi-increasing ramp in the start-up phase 8, which is shown in FIG.
• the speed detection 34 which can be, for example, an incremental encoder or a tachometer generator.
• the actual speed is measured cyclically, the cycle time being adjustable.
• the microprocessor control / regulation 32 is informed via the speed check / detection 31 based on the door activation 30 that there is no longer any standstill of the rotary leaves 10, 11, 12, 13.
• the speed Detection 34 thus reports any speed change to the speed check / detection 31 and thus to the microprocessor control 32.
• the motor support 16 is preferably implemented by means of pulse width modulation, which follows the driving curve of the actual speed 15 of the hand in steps in steps to be determined. However, there is a speed difference ⁇ v 6 in any case, so that constant contact with the rotary wing must be maintained in any case. If the speed of the rotating blades increases, the amount of motor support 16 will also increase, up to a maximum value.
• the descending run-down ramp 7 is traversed, because if the drive motor 14 were switched off directly, it would turn the door open when it was running out, which in turn would be recognized as a new inspection via the speed detection 34, although this was not is available.
• the sequence of movements is realized as in the case of a manual door. If the door is no longer touched by a person, it stops after the entire rotational energy has been reduced. A renewed activation of the door can only take place by means of the turning leaves 10, 11, 12 and 13 which are to be set in motion from the starting position 29, which in turn is recognized by the door activation 30 and is accordingly reported to the microprocessor control / regulation 32.
• the starting phase 8 is shown in the front area. With a certain offset, this start-up phase 8 is followed by motor support 37 to the point where the curve bends to a uniform speed 3. At total speed 9, it can be seen that support speed 4 is always below this, and hence speed difference 6 ⁇ v Part of the speed is that which must be applied by the person before the revolving door passes.
• the force to be applied is plotted against time here.
• the force rises steadily over time until a uniform force 23 is exerted by one of the people on the rotary wing.
• the total force 22 is composed of the support force 24 by the drive motor 14 and the force difference 26 to be applied by the person.
• this force will decrease and the revolving door 10, 11, 12 and 13 will be transferred to the exit ramp 7 due to the program control .
• the microprocessor control 32 is also able to calculate the energy content. This is shown in Figure 6, where the energy is plotted over time. The greatest kinetic energy, which must be made available for the operation of the casement door, is carried by the motor energy 28, the necessary hand energy 27 being significantly lower.
• a revolving door can be operated according to the operating method according to the invention without any safety sensors for the users.
• the peripheral speed of the rotary blades 10, 11, 12, 13 is determined solely by the user, ie if there are several people within the individual cabinets between the individual rotary blades, the person determines the maximum rotary speed of the rotary blades, which has the greatest force exercises the rotating wing in front.
• another person, for whom the circumferential speed is then too high exerts a braking effect, for example by restraining the rotating wing in front of them.
• the overall peripheral speed of the rotary blades is reduced. by virtue of The fact that the swing door contact to be kept constant by the individual persons can be seen as equivalent to a manual revolving door. The consequence of this is that the otherwise necessary sensors for safety can be dispensed with.
• the running sensor system is, for example, a tochogenerator or incremental encoder with which the peripheral speed of the rotating blades is measured.
• the safety sensors are necessary for the area of the safety of people who pass through a motorized revolving door. These are in particular light barriers, infrared detectors, contact mats, sensor strips, radar detectors etc. All these safety sensors make the revolving door extremely expensive.
• the above-described operating method makes it possible to dispense with this safety sensor system, while, at the same time, safe access to such a revolving door opens up a cost-effective alternative for the operator of such a door operated using this method.
• Activating the door from a standstill is not only possible by simply pressing the sash, it can also trigger a button, switch or sensor. Following this, however, it is imperative to establish pressure contact with one of the rotary blades 10, 11, 12, 13 so that the force and thus the rotational speed of the rotary blades can be determined for the support of the drive.
