Definitions
- the invention relates to a method for preventing an impermissibly high driving speed of the load-carrying means of an elevator.
- Conventional lifts are equipped with a safety gear that is activated by a speed limiter when the speed of the load handler exceeds a defined speed limit and brakes and stops the load handler with the maximum permitted deceleration.
- US Pat. No. 6,170,614 B1 discloses an electronic speed limiting system that continuously receives information about the current position of the load suspension device from a position measuring device and calculates the current speed thereof. This current speed is continuously compared by a microprocessor with permanently programmed limit values which remain the same over the entire travel range and which are assigned to specific operating modes of the elevator, for example an upward or downward movement. If the current speed of the load suspension device exceeds the currently active limit value, the electronic speed limitation system activates an electromagnetically operated safety device that stops the load suspension device.
- the electronic speed limit system described has significant disadvantages.
- Every detected exceeding of the active limit value triggers the safety gear and thus an interruption of operation for the elevator, whereby mostly the passengers cannot leave the elevator before a specialist has put the elevator back into operation or brought the load suspension device into the area of an access. Every overspeeding therefore results in braking of the load handler with deceleration values in the maximum permissible range, which is very uncomfortable for the passengers, can cause fear and can even result in injury for frail people.
- the present invention is based on the object
- the speed monitoring device triggers a specific braking measure when a speed limit value assigned to this specific braking measure is exceeded.
- a further braking measure is triggered if a previous braking measure has not led to a defined speed reduction within a defined time.
- a further development of the invention that is particularly advantageous in terms of safety technology is achieved in that a further braking measure is triggered in each case if a speed limit value assigned to this braking measure is exceeded, or if a previous braking measure did not result in a defined speed reduction within a defined time. Both criteria are monitored at the same time and a further braking measure is activated if one of the two criteria is met.
- An embodiment of the method described above has proven to be particularly simple and expedient, in which the drive speed of the load suspension means is to be reduced by applying a permanently stored speed setpoint to a setpoint input of the speed control device.
- Another braking measure that can be used with the method according to the invention is that in a cable-driven elevator with a drive machine and a traction sheave a friction brake acting directly or indirectly on the traction sheave is activated, which is intended to reduce the speed of the load-carrying device or to stop it, previously the Drive machine is switched off. As a result, the load handler is braked with great certainty, so that the use of a safety gear can usually be avoided.
- advantageous braking measures consist in the fact that the speed monitoring device, via a separate flow valve, increasingly restricts the flow of a hydraulic medium or activates a friction brake acting on a piston rod of a hydraulic jack, thereby reducing the driving speed of the load handling device or to shut it down.
- one of the braking measures is that a safety device is provided by the speed monitoring device activated, which is attached to the load handler and, if activated, acts on rails permanently installed along the route and stops the load handler.
- a particularly advantageous embodiment of the method according to the invention consists in that the speed limit values assigned to the individual braking measures, with which the speed monitoring device continuously compares the current driving speed, are dependent on the current position of the load suspension device and contain a reduction in driving speed required in both end regions of the travel path. These speed limits can also depend on a special operating mode (e.g. ramping, inspection, fault mode, etc.). This eliminates the need for conventional deceleration control devices in both end areas of the travel path of the load handling device.
- a special operating mode e.g. ramping, inspection, fault mode, etc.
- the buffers which prevent a hard impact of the load handler at the lower and upper end of the travel path in conventional elevators, can be omitted or built significantly smaller, since the delay caused by the control of the load handler in the end areas of the travel path is monitored in a safety-relevant manner ,
- the speed limit values assigned to the individual braking measures, with which the speed monitoring device continuously compares the current driving speed are expediently fixedly defined and electronically, for example in tables, for each position of the load suspension device on its travel path, possibly as a function of a currently activated special operating mode. saved.
- the permanently stored position-dependent speed limit values give the method according to the invention a high level of functional reliability.
- a further advantageous embodiment of the method results from the fact that the speed limit values assigned to the individual braking measures, with which the speed monitoring device continuously compares the current driving speed, are continuously calculated according to the current position of the load suspension device by a microprocessor integrated in the speed monitoring device.
- the position-dependent, permanently programmed speed limit values and, on the other hand, information provided by the elevator control system about the travel process, in particular speed reductions for floor stops, are included.
- An additional advantageous development of the invention is that after a successful braking measure triggered by overspeed, the elevator automatically resumes normal operation or an evacuation operation, provided the type of the last braking measure and the results of an automatically performed function check of the safety-relevant components permit this.
- a particularly preferred embodiment of the method according to the invention is that all the functions involved in this method are carried out using fail-safe concepts.
- Such concepts include, for example, redundant position and / or speed measuring devices, actuators for activating braking devices in fail-safe

- the current driving speed of the elevator car 8 is calculated in the elevator control 15, which serves, among other things, as feedback of the actual value for the speed control device 14 of the drive motor 9.
- a speed monitoring device 24 has the task of detecting an impermissibly high driving speed of the elevator car 8 and, if necessary, initiating suitable countermeasures. 1A, the elevator control 15, the speed control device 14 and the speed monitoring device 24 are connected to one another via signal and / or data lines, which, however, does not rule out that these devices together in one larger unit can be integrated. The data and signal transmission between these devices on the one hand and the position detection device 21 and the catching devices 18 on the other hand takes place via a hanging cable 25 which rolls between the elevator car 8 and the shaft wall.

- the data and signal transmission between these devices on the one hand and the position detection device 21 and the catching devices 18 on the other hand takes place via a sic-h. below the elevator car 8 rolling cable 25 instead.
- Fig. 2 shows a diagram, the vertical axis of the route (Position in the shaft) and its horizontal axis represent the travel speed of the elevator car 8, which illustrates the relationship between the course of the speed during normal travel and the speed limit values monitored by the speed monitoring device 24.

- a speed monitoring device 24 for example in the form of a table
- Speed limit value curve 28 or several different speed limit value curves 28, which are assigned to different braking measures, are stored. Depending on the activated special operating modes (e.g. ramp travel, inspection, error mode, etc.), these position-dependent speed limit value curves can run differently.
- FIG. 3 shows the same diagram as FIG. 2, but the speed limit curve 28 in the area between the travel end areas additionally also includes the speed curve when stopping on intermediate floors.
- the limit values for these areas are continuously calculated in the speed monitoring device 24 on the basis of speed setpoint information which the elevator controller 15 supplies.

- This first braking measure does not necessarily have to result in the elevator coming to a standstill.
- the elevator can continue its journey according to the program. After a defined short time, which is measured from the moment the first braking measure is activated, the
- Speed monitoring device 24.1 as to whether the speed limit curve 28 is still exceeded and, if necessary (at curve point 31), activates a second braking measure (the mechanical drive brake 10 on the drive motor 9 in FIG. 1A or the caliper brake 58 acting on the piston rod 52 in Fig. 1B), whereby the elevator is to be braked according to the drive brake curve 34.
- the speed monitoring device 24.1 detects that the speed Limit curve 28 is still exceeded, it triggers (at curve point 32) a last braking measure according to this exemplary embodiment, ie it activates the electromagnetically triggered safety device 18, which stops the elevator according to the safety brake curve 35.
- Elevator without exceeding the nominal speed, in a travel path end area or floor stop area exceeds the falling speed limit curve 28 because, for example, the reduction in the actual speed required here does not occur.
- FIG. 6 schematically shows an electronic speed monitoring device 24.1 according to the invention as it is used for the method with a single speed limit value curve 28. It essentially consists of a limit value module 38, a comparator 39 and a reaction generator 40.1 with a timer 44.
- the speed monitoring device 24.1 continuously receives, via its position data input 41, the information generated by the position detection device 21 about the current position of the elevator car 8 in the elevator shaft.
- the speed monitoring device 24.1 receives information about the current actual speed of the elevator via its actual speed input 42 from the elevator control 15.
- the speed limit values assigned to each shaft position continuously become from a table stored in the limit value module 38 read out and compared in the comparator 39 with the current actual speed.
- the comparator 39 determines that the current actual speed exceeds the current speed limit value defined as a function of the position, it sends a corresponding overspeed signal to the reaction generator 40.1.
- the latter immediately activates the first braking measure via one of its brake signal outputs 43.1, 43.2, 43.3, i.e. a permanently stored value is input to a setpoint input of the speed control device 14
- Velocity setpoint or a permanently stored deceleration setpoint At the same time, the timer 44 is started with an adjustable waiting time. If the overspeed signal is still present after the waiting time has elapsed, the reaction generator 40.1 activates the next one
- the speed limit values 28 supplied by the limit value module 38 to the comparator 39 do not always correspond to the position-dependent speed limit values permanently stored in the tables of the limit value module, but rather the stored speed limit values are in the areas where the Elevator controller 15 specifies a reduced speed setpoint, continuously adapted to these reduced setpoints by a processor integrated in limit value module 38. This happens especially when stopping on one floor.
- the limit value module receives the information required for this from the elevator control 15 via a data line 45.
- the method according to the invention can also be used for elevator systems with more than three different braking measures.
- the diagram again contains a curve 27 for comparison, which represents a normal driving speed curve.
- three speed limit value curves 28 are entered.

- this first braking measure does not necessarily have to result in the elevator coming to a standstill. If the second speed limit value curve 28.2 is not also exceeded and the system test device integrated in the elevator control 15 does not report any relevant error, the elevator can continue its journey according to the program. However, if the first braking measure is not effective or is not sufficiently effective, so that the second speed limit curve 28.2 is also exceeded, the speed monitoring device 24.2 activates a second ⁇ at curve point 47. Braking measure (the mechanical drive brake 10 on the drive motor 9 in FIG. 1A or the caliper brake 58 acting on the piston rod 52 in FIG. 1B), so that the elevator accordingly the drive braking curve 34 is to be braked to a standstill.
- the speed monitoring device 24.2 triggers the last braking measure according to this exemplary embodiment at curve point 48, ie it activates the electromagnetically triggered safety device 18 which stops the elevator in accordance with the safety brake curve 35.
- FIG. 9 schematically shows the electronic speed monitoring device 24.2 according to the invention as it is used for the method described in connection with FIGS. 7, 8 with several speed limit value curves 28.1, 28.2, 28.3. It essentially consists of the same modules as the speed monitoring device 24.1 described above in connection with FIG. 6, but for each of the speed limit value curves 28.1, 28.2, 28.3 to be monitored there is a limit value module and a comparator. So it contains three border value modules 38.1, 38.2, 38.3 and three comparators 39.1, 39.2, 39.3 and a common reaction generator 40.2. Via its position data input 41, the speed monitoring device 24.2 on the one hand continuously receives the information generated by the position detection device 21 about the current position of the elevator car 8 in the elevator shaft 1.
- each of the three limit value modules 38.1, 38.2, 38.3, position-dependent speed limit values are stored in a table, the values contained in one of the tables representing one of the three speed limit value curves 28.1, 28.2, 28.3 described with FIGS. 7, 8, that is, each of the tables is assigned to one of the three different braking measures and contains a speed limit value assigned to this braking measure for each position of the elevator in the shaft.
- the speed limit values for the three ' different braking measures corresponding to the current shaft position of the elevator car 8 are continuously read from each of the three tables stored in the limit value modules 38.1, 38.2, 38.3 and assigned to one of the limit value modules 3,8.1, 38.2, 38.3 in each case Comparators 39.1, 39.2, 39.3 compared with the current actual speed. As soon as and as long as one of the comparators 39.1, 39.2, 39.3 determines that the current actual speed exceeds the position-dependent speed limit value stored in the associated table, it sends an overspeed signal to the reaction generator 40.2. Via one of its brake signal outputs 43.1, 43.2, 43.3, the driver immediately activates one of the three possible braking measures that the signaling device Comparator and the corresponding limit value module is assigned.
- the speed limit values supplied by the three limit value modules 38.1, 38.2, 38.3 to the comparators 39.1, 39.2, 39.3 do not always correspond
- the limit value modules 38.1, 38.2, 38.3 receive the information required for this from the elevator control 15 via a data line 45.
- a speed monitoring method that fulfills particularly high safety requirements can be realized by combining the method with time-dependent reaction control according to FIGS. 4, 5, 6 with the method with several different speed limit value curves 28 according to FIGS. 7, 8, 9, each of which a further braking measure is triggered if the previous braking measure did not lead to a defined speed reduction within a defined time, or if one of these further braking measure assigned position-dependent speed limit is exceeded.
- the circuits which are important for the method according to the invention are supplied in the event of a breakdown by suitable emergency power supply devices, for example by means of batteries or capacitors.
