Definitions
- the invention relates to an elevator system with a in a shaft by means of a Drive motor movable elevator car, the drive motor with a Safety switch of a safety circuit evaluating control is interconnected.
- the safety switches in question are, for example Cabin door switches, landing door switches, bolt contacts, emergency limit switches, Deceleration control switch, speed limiter switch, stop switch, Buffer contacts, tension weight switches, inspection switches, slack rope switches etc.
- Safety circuit Is a safety switch of the known elevator systems Safety circuit is not closed, the elevator car will immediately stopped. A technician or the maintenance staff must then ensure that the corresponding safety switch of the safety circuit again is closed in order to free people trapped in the elevator car. If an external technician is required for this, a corresponding one is required Time expenditure, d. H. a period of time until the fitter is on site. It is the maintenance staff, for example, around the caretaker with the Equipped house, so the waiting time is reduced but still not negligibly small. All of this constitutes a not insignificant shortcoming represents.
- the invention is therefore based on the object of an elevator installation at the beginning to create the type mentioned, in the case of a fitter or on Maintenance personnel can be dispensed with if there is a corresponding Safety switch of the safety circuit is open.
- This task is performed in an elevator system of the type mentioned solved according to the invention in that the provided for the drive motor Control has at least one microcontroller in which the Safety circuit is depicted in such a way that the at least one Microcontroller is suitable to drive the drive to carry out an emergency escape switch on when the at least one microcontroller detects that an uncritical for the given situation and / or position of the elevator car Safety switch is open.
- the at least one microcontroller determines that one is for the given situation and / or position of the elevator car uncritical safety switch is open, so The controller controls the drive motor in such a way that automatically, that is without the need for a mechanic or maintenance personnel an emergency escape trip is carried out.
- the physical system of the Safety circuit in software of the at least one microcontroller depicted that means the software of the microcontroller recognizes everyone Safety switch, d. H. its respective switching position (on / off), so that the Control release the drive motor, d. H. can activate if the controller determines that at the given position of the elevator car an emergency escape trip should be allowed.
- a bridge circuit for querying a switch i. H. a microcontroller which The above-mentioned type is described in patent application DE 10314261.4.
- the elevator installation according to the invention has the advantage that in the case of a open but not critical for the given situation or position of the elevator car Safety switch, not immediately an elevator fitter or a Maintenance personnel is required to accommodate people in the elevator car to get out of the pull-out cabin by an emergency rescue trip, but that the Control itself is suitable to activate the drive motor to the emergency exemption perform.
- the at least one microcontroller of the drive motor control be connectable or connected to a remote central office which can be activated by the at least one microcontroller.
- a remote central office which can be activated by the at least one microcontroller.
- Such one Training of the latter type has the advantage that on site Fitter or maintenance personnel can be dispensed with. It is the same possible automatic evacuation, i.e. Emergency exemption from the local remote center to activate. In this case, evacuation only takes place when an emergency call arrives at the control center, i.e. people in the elevator car included who make an emergency call.
- the drive motor 14 is connected to a protective device 18, which is usually has two main contactors 20.
- the protective device 18 is with a Safety circuit 22 interconnected, which is a number in series with each other has switched safety switch 24.
- the safety circuit 22 is with a controller 26 interconnected which has at least one microcontroller 28 has, in which the safety circuit 22 is shown.
- the at least one Microcontroller 28 of controller 26 is suitable for driving motor 14 Carry out an emergency release run when the microcontroller 28 determines that for the given situation or position of the elevator car 12 uncritical safety switch is open. This is shown by the arrow lines 30 and 32 schematically illustrated.
- the activation of the drive motor 14 by the Control 26 for performing such an emergency exemption is by the arrow 34 indicated.
- An acoustic signal device 36 is expediently located in the elevator car 12 provided that is activated during the implementation of an emergency exemption.
- the at least one microcontroller 28 of the controller 26 is expedient bidirectionally connectable to a (not shown) locally remote control center or connected. This is indicated schematically by the double arrow 38.
