Definitions
- the invention relates to a method for the automatic determination of a mass of a door-driven door system having at least one door, wherein a speed change occurring during an acceleration drive is determined.
- door is also to be understood as meaning a single door leaf, a double door leaf, a roller shutter door with a closing and opening direction in any desired positions.
- the invention relates to a control device for automatically determining a mass of a motor-driven door system with at least one door.
- Such doors are used for example as Gebaudeturen, doors in trains or as elevator doors.
- the determination of the effective tower mass and the associated kinetic energy is of great importance for safety reasons.
- the invention has for its object to increase the accuracy of the mass determination.
- the door mass can now be determined by means of the measured and computationally over at least two intervals or operating cycles during an arbitrary drive, thus also during normal operation, without any influence on the driving characteristics of the door. So it can be worked almost with any driving profiles.
- a current driving the motor, a motor voltage, in particular an armature voltage and / or a pulse-width modulation signal is used as the force magnitude. Since the force magnitude, such as a current driving the motor or a motor voltage, in particular an armature voltage, or even a pulse-width modulation signal can be determined metrologically simple, inexpensive and accurate, the simple determination of the engine power quantities is very advantageous for the inventive method .
- the force magnitude is changed at the beginning and / or during acceleration travel. So far, the mass determination had to be done via a constant current, a voltage jump or a constant motor voltage ramp. Now, by using an almost arbitrary force-size profile, for example a sinusoidal profile, the door mass can be determined with an accuracy of less than 10%. The accuracy is now essentially by the resolution of the determined values, such as the speed, the current, the voltage values.
- a separate learning run is carried out as an acceleration drive outside normal operation.
- the advantage of learning trips, which are possibly carried out at a time interval of about 1 year, is that the "aging" of the door system can be detected. Due to the constant operation, for example, the friction in the slide rails may have increased and thus the previously determined value of an effective mass of the door system no longer matches the instantaneous value of an effective mass.
- the change process is preferably logged in an associated automation system in a log file.
- a drive of normal operation is used as the acceleration drive, wherein during normal operation, the mass of the door system preferably automatically from time to time, e.g. once a week, recalculated.
- the mass of the door system preferably automatically from time to time, e.g. once a week, recalculated.
- the door system at least in
- the crawl speed is preferably defined by a speed of less than 10 cm / s.
- a further increase in the accuracy of the mass determination is achieved in that during acceleration travel Starting with the crawl speed from a first point in time, the acceleration starts with a positive value and then returns to crawl speed with a negative acceleration. For example, in a learning run, a ramp with a first slope is created over a certain time. The door system or the door is thereby accelerated. After this acceleration time, the door system or the door is braked with a second negative slope, which can be significantly steeper than the first slope, until crawl speed is reached again.
- This procedure has the particular advantage that even the masses of very light doors can be determined within very small opening widths and the door comes to a halt in good time before it hits an end point.
- a force constant of the motor is used to determine the mass.
- the force constant is the force constant transferred from a torque constant of the motor into a trans- latory system.
- the current to be summed or integrated is formed from a difference between a total current and the friction current, measured in particular during acceleration travel. It is considered advantageous that the specific mass, as an effective mass, contains portions of a translatory mass, a mass of a counterweight and / or a tower cup of a door.
- the specific mass it is advantageous for the specific mass to contain, as an effective mass, portions of a translatory mass, a mass equivalent to the spring force of a spring and / or a tower cup.
- the acceleration drive is achieved by increasing the total flow, in particular beyond the friction flow.
- the friction flow is measured in a separate ride for friction determination.
- the current is increased until the door starts to move.
- a kinetic energy of the door in particular an impact energy, is determined by means of the mass.
- the door system or the engine power or the engine speed can be set in such a way that the impact energy does not exceed a certain limit and thus causes no injuries, for example in the event of a fault.
- the above-mentioned control device for the automatic determination of a mass of a door driven by a motor door system with at least one door preferably for carrying out the method according to one of the method claims, with a first memory for storing a characterizing an acceleration ride course of the driving force of the motor influencing Force size, a second memory for storing a program code, a computing unit for program-controlled mass determination, wherein the memory and the arithmetic unit are designed such that the mass determination is possible for different force size curves in the first memory with unchanged program code.
- the two memories can be organized as different memory areas in a common memory module.
- FIG. 1 each shows a motor voltage curve 1 and 2 for an electrically driven door with a mass m ⁇ .
- a motor voltage U is applied in each case.
- the motor voltage profile 1 is shown via the travel distance S for a drive in the opening direction 6.
- the motor voltage curve 2 is shown on the route S for a drive in the closing direction 7.
- a total current I G for the travel distance of a motor voltage ramp applied for 40 operating-cycle cycles ⁇ t with a slope of one pulse-width modulation increment per operating-system cycle ⁇ t is measured from a first instant or measuring point MPl. For this period, a motor current I is added up.
- the door is fully open.
- To determine the Reibstromes I R comprises wherein the motor voltage curve 1, contrary to the illustration in the figure, a continuous linear profile, without the ramp, from the first measurement point MPl in the opening 6 is measured in a separate learning movement.
- the value for the speed change ⁇ V per operating cycle is determined via an incremental encoder on the motor.
- the incremental encoder provides pulses per unit of time, which are directly proportional to a current speed V.
- the measured motor currents I G and I R and the speed V determined via the incremental encoder or the speed change ⁇ V are inserted into the formula I and the effective door mass m e ff can be determined.
- the respective force with the formula IV is determined at the positions of the route S which correspond to the measuring points MP1 to MP4. If a spring is used for a counter force in the door system, then the largest force F F of the spring is established at the location of the position or measuring points MP2 or MP3.
- a door system with a spring can automatically, preferably solely on the basis of the collected measured values, without this Service technician analyzes the door system, be determined.
- a counterweight can be determined as follows.
- the force F MP 2 at the position MP2 is composed of the friction force F R and the counterweight force F G according to formula VI. After further physical force additions, the counterweight force F G is determined.
- the determined mass m e ff contains, as an effective mass, components of a translatory mass mi in , a mass m G of the counterweight or a mass equivalent to the spring force F F or a combination of both and a door mass m ⁇ Door mass m ⁇ according to formula X. determined.
- the following table shows the mass values of the door determined by the calculation according to the invention in comparison with the actual mass values of the door.
- the example of a door with an actual mass of 300 kg and another door with an actual mass of 200 kg is shown the percentage deviation between the actual mass and the calculated mass is less than 10%.
- the calculated values result from three measurements in each case in which 78 current measurements per 10 ms are evaluated.
- a test run of the door is carried out at a start from a left side or from a right side.
- the effective mass fraction of motor and system or the translatory mass is 10 kg.
