Definitions
- the invention relates to a method and a device for determining the movement and / or the position of an elevator car of an elevator installation, in particular for determining a possible faulty behavior of the elevator installation, as well as an elevator installation according to the preamble of the independent claims.
- the movement and the position of an elevator car are detected in an elevator installation on the basis of sensor devices. It is typically provided that even a possible malfunction of the elevator system, such as an occurring overspeed of the elevator car, is detected in order to trigger the necessary security measures can.
- EP 0 712 804 A1 A method and a device for measuring the speed and for detecting an overspeed in an elevator installation are described in EP 0 712 804 A1.
- the traveling speed of an elevator car guided in an elevator shaft and driven by a drive unit is monitored in order to stop it when an overspeed occurs.
- a measuring strip is mounted on a wall of the elevator shaft and is scanned by a forked light barrier connected to the elevator car.
- the measuring bar has a measuring track with flags, with which the speed of the elevator car is measured. By comparing the measured speed with the predetermined maximum speed, the possible occurrence of an overspeed can be determined and signaled in the sequence.
- the length of the flags is in each case adapted to the maximum speed of the elevator car in the relevant shaft area, ie towards the upper and lower shaft end towards the flag segments are getting shorter.
- the duration of the scanning of the individual flags is therefore included an at least approximately constant limit, if the entire shaft area is traversed at the intended maximum speed. If the duration of the scan of a single flag is shorter than this limit, then there is an impermissible exceeding of the maximum speed.
- the measuring strip also has a control track with window openings, each associated with a flag and arranged at the same height. If the measuring bar and the forked light barrier are installed correctly, the markings of the measuring track and the control track are scanned correctly. On the basis of the scanning of the window openings of the control track is thus checked whether the fork light barrier sufficiently deep into the measuring strip engages and the sequential interruption of the light barriers is ensured by the flags during the journey of the elevator car. By scanning the control track can also be determined whether individual flags are missing on the measuring bar, whereby the speed measurement would be distorted.
- the flags of the measuring track and the window openings of the control track are dimensioned and arranged such that always at least one light barrier is interrupted. If the photocells and the control track associated light barriers are not interrupted at the same time, therefore, there is an error that occurs, for example, when the fork light barrier has detached from the measuring bar.
- the measuring strip in addition to the measuring track and the control track to a safety track, which serves the additional control of the elevator car in the upper and lower end of the hoistway.
- the fork light barrier has a first and a second optical channel with independent light barriers whose signals are supplied to a first and a second measuring channel. If the measurement results of these two measurement channels deviate from each other, an error is detected that is due, for example, to a failure of a single optical component.
- faults can occur which jeopardize the safe operation of the elevator installation.
- identical errors can occur in both channels of the forked light barrier.
- damage to the measuring strip or permanent effects of foreign bodies can occur. If the aforementioned defects occur at the fork light barrier or at the measuring strip, the markings of the measuring strip are no longer scanned correctly, which is why a correct measurement of the speed and thus also detection of an overspeed are no longer possible.
- the displayed states do not contain an immediately clear indication of the actual state of the elevator installation. For example, a condition may occur in which all photocells are interrupted by the measuring bar. This condition may occur for a long time when the elevator car is stopped at a corresponding position within the hoistway. However, the same condition may also occur when the elevator car is in motion and one of the above errors occurs. On the basis of the available information can therefore not be clearly determined whether the elevator car is held at a certain position or moves along the elevator shaft.
- the present invention is therefore based on the object to provide a method and an apparatus for reliably determining the movement and / or the position of an elevator car of an elevator installation, by means of which the deficiencies described above are avoided. Furthermore, an elevator system provided with this device and operating according to this method is to be specified.
- the method and the device which are intended in particular to reliably detect a faulty behavior of the elevator installation, in particular an overspeed, should be able to be implemented with simple measures and lead to a significant improvement in the reliability of the monitoring of the elevator installation.
- the method and the device which serve to reliably determine the movement and / or the position of an elevator car of an elevator installation, have a first monitoring unit from which first signals of a first sensor device are evaluated in order to obtain information on the movement and / or position of the elevator car to determine and detect any occurring misbehavior of the elevator system and to trigger appropriate safety measures, which relate for example to the dropping of safety switching elements and thereby the shutdown of the elevator.
- a second sensor device which does not operate according to the principle of the first sensor device is provided, by means of which changes in the state of motion of the elevator car are detected and corresponding second signals are output to a second monitoring unit, which evaluates the second signals and detects changes in the state of motion of the elevator car, after which it is checked whether motion signals determined by the first monitoring unit are coherent with the changes in the state of motion of the elevator car detected by the second monitoring unit. If there is no coherence, a first error signal is generated.
- the first monitoring unit determines, for example, the speed of the elevator car based on an optical first sensor device, then disturbances occurring there, as described above, are not relevant for an electromechanical second sensor device, based on which the second monitoring unit detects the occurrence of changes in the state of motion Elevator car detected. Conversely, disturbances which might possibly occur in the electromechanical second sensor device are of little significance for the optical first sensor device.
- monitoring units operate according to different principles or in different technical sub-areas, which is why a higher information gain is achieved when comparing the corresponding work results, as compared with additionally obtained measured variables in the same technical sub-range.
- a securing track is provided, the scanning of which supplies additional information.
- the sampling of all three paths can be affected simultaneously by the same cause. For example, all three tracks can be covered by foreign bodies. Furthermore, all light sensors can be disturbed by extraneous light at the same time, or all light sensors can also be covered by foreign bodies. Furthermore, it is to be expected that if the measuring strip is damaged, all three tracks will be damaged, which is why the addition of an additional track, which is also optically scanned, does not give the desired improvement.
- the inventive device Due to the system-related decoupling of the first and second sensor device results in the inventive device a reduced susceptibility to simultaneously occurring disorders. If the first and second monitoring units are also electrically decoupled enough, the solution according to the invention results in a significantly increased security gain with little effort. A mutual check of the first and second monitoring unit therefore makes it possible to immediately detect any faults and to protect the elevator system from danger.
- first and second monitoring unit relate to the movement of the elevator car both monitoring units allowed.
- first and second monitoring unit it is sufficient to monitor the coherent or coherent occurrence of mutually corresponding signals of both monitoring units. If the elevator car is accelerated, first or second signals corresponding to one another are output from the first optical sensor device which is guided along a stationary measuring strip and from the electromechanical second sensor device if both sensor devices are functional and thus operate coherently with one another.
- a check as to whether there are also second signals in the presence of first signals which signal a movement or a change in the movement of the elevator car and signal a corresponding change in the movement of the elevator cabin therefore makes it possible to verify that both monitoring units and the associated sensor devices are in proper operation .
- Various signals can be used for the test, which indicate contiguous states.
- the mutually corresponding measurement signals typically occur with a mutual time shift, which can also vary within a certain range.
- at least one time window is provided, within which the occurrence of two mutually corresponding signals or messages of both monitoring units is monitored.
- the time window is opened after a corresponding signal has been detected in one of the monitoring units.
- the second sensor device comprises at least one electromechanical motion sensor, such as an acceleration sensor and / or a speed sensor.
- An acceleration sensor is a sensor normally provided with a test mass, with which the acceleration is measured by determining the inertial force acting on the test mass as acceleration or deceleration occurs.
- the gravitational acceleration acting on the test mass is preferably compensated electrically or electronically, so that the signals emitted by the acceleration sensor indicate the further accelerations acting on the acceleration sensor, which are typically due to the actions of the drive device and the brake device. From Tietze-Schenk, semiconductor circuit technology, Springer-Verlag, Heidelberg 1 999, 1 1. Edition, page 1223, an acceleration sensor is known in which the test mass acts on a membrane provided with strain gauges.
- a capacitively or inductively operating sensor can be used as an acceleration sensor, in which the test mass is suspended elastically and acts as part of a capacitor or is moved as a magnet within a coil.
- piezoelectric acceleration sensors are known.
- a speed sensor may, for example, have an impeller rolling in the elevator shaft, which is coupled to a measuring transducer.
- the second sensor device comprises a transducer connected to the drive and / or brake device, which detects causes that lead to a later change in the movement of the elevator car.
- signals are generated which relate to changes in the state of motion of the elevator car, which are compared within a correspondingly selected time window with signals of the first sensor device corresponding thereto in order to determine whether the measurement results are coherent.
- the choice of the size of the time window is preferably dependent on the intended speed of the elevator car, the signal to be compared. le and the measuring and evaluation methods used. If a movement change has already occurred and has been detected by the acceleration sensor, then the time window is selected to be correspondingly small. If, on the other hand, a control command for starting up the installation has been determined in the drive and / or braking device, then the time window is selected to be correspondingly larger.
- the applied measuring method is also taken into account.
- the time window is selected according to the distances of the markings of the measuring strip.
- the first sensor device is a light barrier device mounted on the elevator car, which has first optical elements which serve to form at least a first light barrier, with which at least the markings of a measuring path of a measuring strip, which is mounted stationary in the elevator shaft, are scanned while the elevator car is moving , From the first signals emitted by the first sensor device, the first activation signals are determined in the monitoring unit.
- first optical elements which serve to form at least a first light barrier, with which at least the markings of a measuring path of a measuring strip, which is mounted stationary in the elevator shaft, are scanned while the elevator car is moving .
- the first activation signals are determined in the monitoring unit.
- edge transitions or movement signals occur within the signal train, which indicate the closing or opening of the light barrier and thus the movement of the elevator car.
- the time interval of these motion signals is inversely proportional to the speed of the elevator car.
- the opening or interruption of the light barrier and thus a corresponding movement signal must be determined by the first monitoring unit within a correspondingly selected time window. By checking the arrival of the motion signal, therefore, the coherent operation of the two monitoring units can be verified.
- the second signals emitted by the acceleration sensor and / or by the speed sensor and / or by the measuring transducer are evaluated in order to detect impermissible operating signals.
- conditions such as acceleration values lying above a limit value or speed values lying above a limit value or drive quantities lying outside a tolerance range, wherein a second error signal is generated after determination of values which are above a limit value or outside the tolerance range.
- Malfunctions can be detected early on the basis of the second monitoring unit, possibly before an overspeed has occurred and has been detected by the first monitoring unit. In this case, not only the proper function of the first monitoring unit, but the behavior of the elevator system is independently monitored by the second monitoring unit.
- the first and / or second sensor device as well as the first and / or second monitoring unit are formed at least partially redundant.
- the output signals of mutually corresponding redundant parts of these devices are compared with each other, wherein after occurrence of a difference, a third error signal is generated.
- the first sensor device and at least a part of the second sensor device are preferably arranged in a common housing. In this way, a compact design of the sensor is possible.
- at least the acceleration sensor is constructed as a micro-electro-mechanical system (MEMS) and, for example, cast into the housing of the two sensor devices.
- MEMS micro-electro-mechanical system
- Corresponding micro-electro-mechanical sensor devices which can be integrated into the housing of the first sensor device without difficulty are described, for example, in WO20091 17687A1.
- the sensor system of the second sensor device is preferably designed redundantly or multi-channel, so that a fault can be detected by comparing the signals of the different channels.
- the single or redundant trained first and / or the second monitoring unit in the common Housing integrated the sensor devices. This results in a total of a compact and cost-effective design of the entire monitoring device, which can be realized for example in the form of a forked light barrier. In a preferred embodiment, two separate or interconnected such forked light barriers are used.
- the device according to the invention On the basis of the device according to the invention not only the overspeed of an elevator car can be reliably detected. It can also be determined whether a stop of the elevator car reported by the first monitoring unit actually exists. If an above-described error occurs in the first monitoring unit, the first sensor device or the measuring strip during the travel of the elevator car, it is possible that no movement signals will arrive from the first monitoring unit. This could be interpreted as the onset of hibernation of the elevator car, although it is still in progress.
- the checking according to the invention of the coherence of the measurement results of the first and second monitoring unit makes it possible to detect the error mentioned.
- the size of the time window is preferably adjusted accordingly, within which a coherent confirmation of the change in movement is expected by the other monitoring unit. This not only determines whether the two monitoring units are in operation, but also whether they are working correctly.
- the inventive method can therefore be advantageously used to check changes in the state of the elevator system and the state of monitoring devices and control devices.
- the monitoring device or at least the monitoring units provided therein are preferably connected to the central control unit of the elevator installation and / or to a shaft information system which detects position data and / or movement information of the elevator car and transmits it to the control unit.
- the exchange of information and signals between the sensor devices and the monitoring units and the control unit and the shaft information system can take place by means of wireless or wired transmission devices or a combination thereof.
- the second monitoring unit can alternatively or additionally also process other information and signals, such as position signals and RFID signals, which reflect the status of the elevator installation.
- other information and signals such as position signals and RFID signals, which reflect the status of the elevator installation.
- the tolerance ranges e.g. the time window is reduced, if it was reported by the shaft information system that the elevator car is located in the lower or upper end of the elevator shaft.
- FIG. 1 shows a schematic representation of an elevator installation 1 according to the invention, which has a monitoring device 4 with a first and a second monitoring unit 42, 43, which are coupled to sensor devices 2, 31, 32, 33, by means of which the movements of one in an elevator shaft 9 vertically movable elevator car 1 1 can be detected in various ways;
- FIG. 2 shows a forked light barrier 2 known from EP 0 712 804 A1 a measuring strip 5 with a measuring track 51 and a control track 52, by means of light barriers LSMB-AI, LSMB-BI; LS M B-A2, LS M B-B2, LS K BA, LSKB-B which are detected by optical elements 21 A, 22 A; 23A, 24A; 21B, 22B; 23B, 24B; 25A, 26A; 25B, 26B of the forked light barrier 2 of Figure 2 are formed;
- FIG. 1 a diagram showing the course of the signals S-51, S-52 of the fork light barrier 2 of Figure 3, which shows that the corresponding light barriers LSMB-AI and LSKB-A, after a time T2 are closed and therefore either the elevator car 1 1 at a certain position was stopped or an error occurred; a diagram showing waveforms the first signals S-51, S-52 of the fork light barrier 2 of Fig. 3 and second signals S-31, S-32 of an acceleration sensor 31 and a speed sensor 32 and the course of corresponding counts Z1, Z2, which be compared with limit values in order to check the coherence of the measurement results of both monitoring units 42, 43; and a detailed functional block diagram of the monitoring device 4 of FIG. 1.
- the elevator installation 1 shows a schematic representation of an elevator installation 1, which has an elevator car 1 vertically movable in an elevator car 1 1, which is connected via cables 12 and a traction sheave 13 with a drive unit 14.
- the elevator installation 1 is further provided with a device according to the invention, by means of which the speed and any overspeeds of the elevator car 1 1 can be detected.
- the inventive device is constructed such that an error occurring therein can be reliably detected and the elevator system 1 can be secured accordingly.
- the device according to the invention comprises a monitoring device 4, in which two mutually independent monitoring units 42, 43 are provided, in which, in this preferred embodiment, a reference clock t RE F will be supplied from a shared time base 41.
- the first monitoring unit 42 is connected to a sensor device 2 shown in FIG. 2, which in the embodiment shown corresponds to the forked light barrier 2 known from EP 0 712 804 A1.
- This fork light barrier 2 has two channels and comprises pairwise optical elements, namely transmitters 21A, 23A, 25A and receivers 22A, 24A, 26A for the first channel and transmitters 21B, 23B, 25B and receivers 22B, 24B, 26B for the second channel , on the basis of whose light barriers LSMB-AI, LSMB-A2, LSKB-A, for the first channel and light barriers LSMB-BI, LSMB-B2, LSKB-B are formed for the second channel.
- the measurement signals generated on the basis of the light barriers of the two channels A and B are processed independently of one another and can be compared with one another in the first sensor device 2 or in the first monitoring unit by means of a comparator in order to detect malfunctions. For the following considerations, it is sufficient to consider the first and the third light barrier LSMB-AI, LSKB- A of the first channel.
- the fork light barrier 2 is arranged, for example, on the roof of the elevator car 1 1 in such a way that it embraces on one side a measuring strip 5 vertically aligned and stationarily mounted in the elevator shaft 9. While the elevator car 1 1 is being driven, the forked light barrier 2 scans the markings 51 1, 512 of a measuring track 51 and a control track 52, which run parallel to one another along the measuring strip 5.
- the measuring track 51 has markings 51 1 in the form of exposed flags whose width decreases towards the end areas of the elevator shaft 9, in which a steadily decreasing maximum speed is prescribed.
- the flanks of the markings 51 1 are always run through the designated first photocell LSMB-AI in equally long intervals in a drive at maximum speed. In this case, also occur almost constant time intervals between the corresponding edges of the output from the forked light barrier 2 signals. These constant time intervals assume at maximum speed of the elevator car 1 1 a minimum value, which is selected as a limit. If this minimum value or limit value is undershot, there is an overspeed.
- an error signal F42 is output by the first monitoring unit 42 to a security module 44, which triggers, for example, the release of security switching elements and stops the elevator car 1 1, as described in EP 0 712 804 A1.
- a security module 44 which triggers, for example, the release of security switching elements and stops the elevator car 1 1, as described in EP 0 712 804 A1.
- the second light barrier LSMB-A2 which also scans the measuring path 51, it is determined whether a mark 51 1 happened or only touched.
- window openings 521 are provided at the height of the markers for 1 1 1 of the measuring path, which are scanned by means of the third light barrier LSKB-A of the forked light barrier 2. If the control track 52 is scanned correctly, it is ensured that the measuring strip 5 engages deep enough in the fork light barrier 2. If, however, the corresponding signals from the third light barrier LSKB-A do not occur, a further error signal is output to the security module 44.
- each marking 51 1 of the measuring track 51 is opposite to a window opening 521 of the control track 52.
- the width of the markers or lugs 51 1 of the measuring path 51 is greater than the width of the window openings 521, which ensures that during normal operation always the first or third light barrier LSMB-AI, LSKB-A of the forked light barrier 2 is interrupted. If the first and the third light barrier LSMB-AI, LSKB-A are open at the same time, an error is detected.
- a state is permissible in which both the first and the third light barrier LSMB-AI, LSKB-A of the forked light barrier 2 are interrupted.
- This state which can last for a long time when the elevator car 1 1 stops at a certain position, is thus not interpreted as an error.
- this condition may actually be erroneous and caused, for example, by a foreign matter 8 become.
- a defect of an optical element 21A, 23A, 25A, 22A, 24A, 26A, or a defect in the first monitoring unit 42 may cause the aforementioned condition. This state is therefore not clear, which is why corresponding dangers result.
- FIG. 5 shows a diagram with signals S-51, S-52 of the forked light barrier 2, from which it can be seen that the corresponding light barriers LSMB-AI and LSKB-A are closed at the times T1 and T2.
- both light barriers LSMB-AI and LSKB-A are closed by the measuring strip 5 and are subsequently opened again, so that two flank signals S-51 F and S-52F can each be detected in the first monitoring unit.
- the light barriers LSMB-AI and LSKB-A remain permanently closed, so that either the elevator car was stopped at the position shown in Fig. 4 or a safety-related error has occurred.
- the monitoring device 4 has a second monitoring unit 43, which is connected to a second sensor device 31, 32, 33, detected by means of the changes of the state of motion of the elevator car 1 1 and corresponding second signals S-31; S-32; S-33 are delivered to the second monitoring unit 43.
- the second sensor device 31, 32, 33 comprises an acceleration sensor 31 and a speed sensor 32, which are connected to the elevator car 1 1.
- the acceleration sensor 31 may operate according to one of the principles described above.
- the speed sensor 32 has a transmitter, which is coupled to an impeller 321, which is guided along the shaft wall, for example in a rail.
- signals S-31; S-32 delivered which signal the changes in the state of motion of the elevator car 1 1.
- the second sensor device comprises a transducer 33 connected to the drive device 14 and preferably also to the brake device, from which signals are monitored which indicate the initiation of changes in the movement of the elevator car 1 1.
- the signals S-31; S-32; S-33 of the second sensor device 31, 32, 33 therefore evaluated to determine whether or not expected changes in the state of motion of the elevator car 1 1.
- After detection of a change in the state of motion of the elevator car possibly only during acceleration from the idle state or, if necessary, during acceleration or deceleration from a constant speed drive, it is checked whether the movement signals S-51 determined by the first monitoring unit 42 F and the detected by the second monitoring unit 43 changes in the state of motion of the elevator car 1 1 are coherent to each other, wherein in the absence of coherence, an error signal is generated.
- the verification of the coherence of the measurement results determined by the two monitoring units 42, 43 may be limited to checking a single signal S-51F or may involve the comparison of further determined kinematic information.
- this status change is also to be registered by the first monitoring unit 42 if it is functional.
- the measurement results of the two monitoring units 42, 43 are therefore coherent during trouble-free operation and are checked one-sidedly or mutually in order to determine any occurring error.
- the movement signals S-51F ascertained by the first monitoring unit 42 are transmitted to the second monitoring unit 43, where they are checked for coherence.
- the validity of the measurement results of the second monitoring unit 43 can also be checked by the first monitoring unit 42. After the detection and measurement of edge signals S-51 F, it is checked whether the changes in the movement state determined by the second monitoring unit 43 are coherent thereto. For this purpose, the measurement results S-43 of the second monitoring unit 43 are transmitted to the first monitoring unit 42 and evaluated there accordingly.
- the examination of the monitoring units 42, 43 can therefore be one-sided or mutually.
- errors that may occur in the first or second sensor device 2, 31, 32, 33 or in the first or second monitoring unit 42, 43 are detected and signaled immediately.
- the mutual checking of the two monitoring units 42, 43 takes place in a separate module 45 (see FIG. 7).
- the monitoring device 4 is preferably connected to the control unit 6 and / or to a shaft information system 7.
- the monitoring device 4 current operating data such as changed maximum values for accelerations and speeds can be transmitted.
- Data of the shaft information system 7 can be used to individually take into account the respective position of the elevator car 1 1 in the evaluation of the first or second signals S51, S-31, S-32, S-33.
- FIG. 6 shows the course of the signals from FIG. 5 after the time T2.
- the elevator car 1 1 was stopped at time T2 and accelerated again at time T3.
- no movement signals S-51 F, S-52F occur in the signal paths S-51, S-52.
- a movement signal S-51F, S-52F does not occur directly, since the first and the third light barriers LSMB-AI, LSKB-A are normally removed from the flanks of the markings 51 1, 521 of the measuring strip 5 , as shown in Fig. 4.
- a time window W is opened and it is checked whether a movement signal S-51 F arrives from the first monitoring unit 42 within this time window W, indicating that the first light barrier LSMB-AI has been opened or closed.
- a counter acted upon by the reference clock t RE F (counter 433 in FIG. 7) is started at the time T4.
- the current count is compared in the sequence in each case with a limit G1, which may not be exceeded and would be reached at the time T8, if no motion signal S-51 F arrives.
- the limit value is reached at the time T8, the first error signal F1 is output to the fuse module 44, as shown in FIG.
- FIG. 6 it is shown that within the course of the signal S-51, however, even before reaching the time T8, namely at the time T7, a movement signal S-51 F or the opening or closing of the first light barrier LSMB-AI and thus the proper Function of the first sensor device 2 and the first monitoring unit 42 has been detected.
- the counter is reset and restarted to monitor the occurrence of the next edge change and the next motion signal S-51F, respectively.
- a new time window W is simultaneously opened, within which the arrival of the next movement signal S-51 F is monitored. The monitoring is terminated in this preferred embodiment only when the stoppage of the elevator car was 1 1 detected.
- the stoppage of the elevator car 1 1 can in turn be determined in various known ways. If no movement signals S-51 F arrive from the first monitoring unit 42, the resting state of the elevator car 1 1 is thereby displayed. Preferably, the coherence of the measurement results of the first and second monitoring unit 42, 43 is also checked in this case. In this case, it is checked whether the second monitoring unit 43 has detected a corresponding change in movement or an acceleration opposite to the direction of movement of the elevator car, which can lead to a standstill of the elevator car 11. If the measurement results of both monitoring units 42, 43, however, are not coherent, an error signal is emitted again. As illustrated in FIG. 6, the coherence of various signals, events, and information within individual time windows may be compared.
- a speed change is detected.
- a second counter is started and its count Z2 compared with a limit. This second counter is reset on the occurrence of a falling edge S-52F of the signals S-52.
- a limit value G2 is shown, by which a maximum speed of the elevator car 1 1 is fixed. If the counter (see the counter 423 in FIG. 7) does not reach this limit value G2 before it is reset, the time interval between the movement signals S-51 F is too low, which is why the travel speed of the elevator car 1 1 is above the maximum speed.
- FIG. 6 based on the characteristics of the signals S-31, S-32 emitted by the acceleration sensor 31 and by the speed sensor 32, it is illustrated that various fault events E1, E2, E3 can occur which are safety-relevant and should be signaled as errors.
- the course of the output from the acceleration sensor 31 signal S-31 shows that too high Accelerations may occur (event E1) or that an acceleration may take too long (event E2), which is why the occurrence of an overspeed is expected.
- the course of the signal S-32 output by the speed sensor 32 is shown, from which the exceeding of the limit value GVMAX of the maximum speed can be read off directly.
- FIG. 7 shows a detailed functional block diagram of the monitoring device 4 of FIG. 1 with the first monitoring unit 42 to which signals S-51, S-52 are supplied from the first sensor device 2 and the second monitoring unit 43, the signals S-31, S 32, S-33 are supplied from the acceleration sensor 31, the speed sensor 32 and the transducer 33.
- the two monitoring units 42, 43 to which clock signals t RE F are supplied from a shared time base 41, evaluate the supplied signals S-51, S-52; S-31, S-32, S-33 and the signals S-51F, S-43, exchanged between the two monitoring units 42, 43, and transmit corresponding error signals or error messages F1, F5 to the fuse module 44 after the detection of disturbances , which transmits corresponding control signals C to the drive device 14 and corresponding information to the control unit 6.
- the first signals S-51, S-52 output by the first sensor device 2 are supplied in the first monitoring unit 42 to an edge detector 421 which transmits motion signals or edge signals S-51F, S-52F to an evaluation unit 422.
- the time intervals of the occurrence of the movement signals S-51 F, S-52F are checked by the evaluation unit 422 using a counter 423 to determine whether these time intervals are not below a limit (see limit G2 in Fig. 6), which accordingly the maximum permissible speed is selected.
- the evaluation unit 422 also transmits ascertained events, movement information or even individual movement signals S-51 F to the second monitoring unit 43.
- the second signals S-31, S-32, S-33 emitted by the acceleration sensor 31, the speed sensor 32 and the measuring transducer 33 are fed in the second monitoring unit 43 to a detector unit 431 which transmits relevant changes of motion and state changes to an evaluation unit 432.
- the evaluation unit 433 checks whether the detected movement changes and state changes lie within the specified limit values and tolerance ranges. Furthermore, the evaluation unit 433 checks whether the detected movement changes and state changes are coherent with the events, movement information or movement signals S-51 F reported by the first monitoring unit 42.
- a counter 433 is provided by which a time window W is determined, within which it is checked whether the mutually corresponding events, information and signals occur and the first and second monitoring unit 42, 43 work coherently.
- FIG. 6 also shows that the movement changes and state changes determined by the second monitoring unit 43 are also communicated to the first monitoring unit 42 by means of a message S-43, which in turn checks whether the communicated movement changes and state changes are coherent with their own measured values are. In this way, a malfunction that has occurred in the second sensor device 31, 32, 33 or in the second monitoring unit 43 can also be determined.
- the check for coherence of the measurement results of the two monitoring units 42, 43 is carried out in a preferred embodiment in a separate test module 45.
- further data can be taken into account by the test module 45, which data are reported, for example, by at least one further monitoring unit or the control unit 6.
- the elevator expert can arbitrarily change the set shapes and arrangements.
- any sensor devices can be used, by means of which kinematic variables can be detected.
- the solution according to the invention is arbitrarily scalable and can also additionally take into account further information, for example information of the shaft information system, and thus be adapted to the respective requirements of the user.
- the use of acceleration sensor 31, speed sensor 32, and transducer 33 is shown as second signals S-31, S-32, S-33.
- the elevator expert can use these different sensors in combination but also individually.
- first and / or the second sensor device 2, 31, 32, 33 and / or the first and the second monitoring unit 42, 43 can optionally be integrated in a unit, for example in a common housing or in a common measuring body, so that a single functional unit is formed.
- the forked light barrier 2 not only optical elements 21 A, 22 A; 23A, 24A; 21B, 22B; 23B, 24B; 25A, 26A; 25B, 26B for the realization of the light barriers LS M B-AI, LS M B-BI; LS M B-A2, LS M B-B2, LS K BA, LS K BB, son ⁇ also an acceleration sensor 31A for a first channel and an acceleration sensor 31 B for a preferably provided second channel, the total in the body 28th the fork light barrier 2 are integrated. Furthermore, the first and / or the second monitoring unit 42, 43 can be integrated into the body 28 of the forked light barrier 2.
- the acceleration sensor 31 encloses all elements required for measuring the acceleration, in particular the test mass, in a housing, its use in combination with an arbitrarily designed first sensor device 2, in particular a fork light barrier, is particularly advantageous.
- the installation of the acceleration sensor 31 in the fork light barrier 2 requires little additional space.
- the combination of the first and second sensor devices 2, 31 provides a complete sensor unit which can monitor itself and which does not require any further information to be fed in from outside for this purpose.
- the speed sensor 32 and the transducer 33 may additionally be used if a further increase in the reliability of the measurement results is desired. Furthermore, the speed sensor 32 and / or the transducer 33 can also be used as an alternative to the acceleration sensor 31.
- the first and / or the second sensor device 2, 31, 32, 33 can be constructed as single-channel or multi-channel.
- Fig. 7 therefore shows only one embodiment in which only the possibility of using a plurality of sensors 31, 32, 33 for the second sensor device is shown. In practical application, at least one of the aforementioned sensors 31, 32, or 33 is present in each case.
- At least the second monitoring unit 43 has a filter stage, by means of which disturbances are eliminated which could lead to false alarms.
- the filter stage e.g. is integrated in the detector unit 431, in particular, signals are suppressed, e.g. due to irrelevant vibrations.
