Definitions

the invention relates to a method for controlling the brake (s) of a passenger conveyor system, such as an escalator or a moving walk.
Escalators and escalators must be equipped in accordance with applicable domestic and foreign safety regulations so that they stop automatically before the speed exceeds, for example, 1.2 times the nominal speed. In the same way, a shutdown must be brought about as soon as faults occur in the area of the escalators or the escalator, for example when a safety switch is actuated.
Another disadvantage is that when the brake pads wear, the braking distance is extended, even if the brake is applied suddenly.
the aim of the subject matter of the invention is to design a method and a device for regulating the brake (s) of a passenger conveyor system, such as an escalator or a moving walkway, which allows the braking distance to be largely the same even when brake linings are worn, without causing personal injury.
This goal is achieved by a method for controlling the respective brake of a passenger conveyor system, such as an escalator or a moving walk, by monitoring the control signals of the drive motor and the brake by means of several processors, in the event of malfunctions occurring in the area of the passenger conveyor system, the brake suddenly applied the brake (s) is relieved in a defined manner upon detection of delay values and then the passenger conveyor system is shut down via the processors within a predefinable time interval.
a device for regulating the respective brake of a passenger conveyor system with at least two mutually monitoring processors which are connected to switching elements of the brake via driver elements.
the principle of the control device according to the invention is thus based on the safety regulations applicable at home and abroad.
This type of control of the brake (s) which has not yet been implemented in escalators and moving walks, corresponds to the current state of the art and also meets the relevant domestic and foreign safety standards.
the control is based on the fuzzy logic known per se.
a wide variety of minimum and maximum values are stored in the memory, by means of which at least one average value is generated, on which the processors or the braking behavior are based.
the respective brake remains released as in the previous state of the art. As before, the brake engages suddenly in the event of malfunctions. Are there additional malfunctions in the area of the control unit (at least one processor), i.e. If no delay is determined via the control unit, the brake remains applied and thus moves in the known prior art.
the control scheme provides that the respective brake is released again in a defined manner, whereby the state of full braking is improved in favor of the persons on the escalator or the moving walkway.
the people on the escalator or the moving walkway notice that the brake is applied when there is a brief deceleration.
the respective brake is vented again, so that the brake can then be shut down in a controlled manner within a braking distance corresponding to the safety standard and without an injury to persons.
the mutually monitoring processors form a so-called security system.
Each of the processors controls at least one driver element, since the processors themselves are not able to generate 24 V signals. This takes place in the area of the respective driver element, whose 24 V signal in turn serves as the control voltage for the respective switching element of the respective brake.
the switching element is usually a brake magnet.
the driver elements represent a two- or multi-channel system that can bring the brakes to a standstill even if one processor fails. In this respect, even in the event of a processor failure, the full braking of the passenger conveyor system already known in the prior art is ensured in any case.
the processors also act on control relays via which the drive motor can be switched off as soon as the brake is applied. This has the advantage that the braking force does not have to work against the running engine and thus possibly causes further damage here.
the single figure shows the control device 1 according to the invention. For simplification, only the components relevant to the invention are shown.
the drive motor 2 of an escalator or a moving walk (not shown further) and the brake 3 which can be brought into operative connection with it can be seen.
the control device 1 comprises two mutually monitoring microprocessors 4, 5. Each of the microprocessors 4, 5 is operatively connected to a driver element 6, 7. In addition, each of the microprocessors 4, 5 acts on an associated relay 8, 9.
the processors 4, 5 are in operative connection with one another via a signal line 10, so that their operating behavior can be mutually monitored. Via further lines 1 1, 1 2, 1 3, 14, the processors 4, 5 are in operative connection with the associated driver elements 6, 7.
Additional signal lines 1 5, 1 6 are provided between the drive motor 2 and the respective processor 4, 5.
the driver elements 6, 7 are operatively connected to one another via a line 1 7, which acts as a continuation of the same as line 1 7 'on switching elements of the brake 3, which are not shown.
the relays 8, 9 are connected to the drive motor 2 via switches 1 8, 1 9 and a single line 20. If there had previously been malfunctions in the area of the passenger conveyor system, the brake 3 would have applied suddenly, as a result of which the motor 2 would also have been stopped. The full braking would, however, under certain circumstances lead to people who are on the passenger conveyor system possibly falling down, since a sudden deceleration of the passenger conveyor system begins.
the control is based on the fuzzy logic known per se, with minimum and maximum values being stored in the area of the processors, so that at least one mean value given in accordance with the safety standards can be generated, on which the control scheme for the brake 3 is based.
the processors 4, 5 monitor each other so that they always have the same data status.
the control element of the brake 3 (not shown) remains energized, ie the brake 3 is relieved, so that the drive motor 2 can work without braking.
the drive motor 2 is stopped via the relays 8, 9 and the line 20, so that the braking energy acting does not have to work against the running motor.
the processors 4, 5 now determine deceleration values in the area of the drive motor 2, the control scheme according to the invention applies, namely that the brake 3 is relieved in a defined manner via the associated switching elements and the stopping of the passenger conveyor system within a predetermined braking distance and time interval corresponding to the safety standard is brought about.
the people on the passenger conveyor system thus feel a brief delay pulse, which is not continuous, but is rather canceled again, so that personal injury can no longer occur as a result of the regulation according to the invention.
the brake 3 is suddenly applied via the associated driver 6 or 7 and the line 1 7 or 1 7 ', ie a - as known in the prior art - brought about full braking.
