Elevator installation and call control for use in one

elevator system

The invention relates to an elevator installation and a call control system for use in an elevator installation according to the preambles of the independent claims.

EP1308409A1 discloses an elevator installation with terminals, a job manager for call control, with elevator control and elevator car, in which a terminal on an input floor detects an identification code of a passenger, whereupon the identification code is assigned a passenger profile of a database with a predefined destination floor. The terminal transmits a driving request with information about the input floor and the destination floor of the passenger to the call control. The call control processes travel orders for this information and transmits the travel orders to the elevator control. The elevator controller executes the driving orders and controls the elevator car to carry the passenger from the input floor to the destination floor. While the terminal, the data memory and call control via a signal bus such as Local

Operating Network (LON) or Ethernet communicate with each other, the call control and the elevator control communicate via a parallel logic bus. Both the database and the call control are formed as a printed circuit board, which board next to an adapter to the signal bus also has an interface to the parallel logic bus.

Object of the present invention is to further develop this elevator system or call control.

This object is achieved by the invention according to the characterizing features of the independent claims. The invention relates to an elevator installation with at least one terminal for detecting at least one driving request, with at least two call controls for the preparation of driving orders for the driving request and with at least two elevator controls for the execution of driving orders, the terminal and the call controls via signal bus Adapter in at least one signal bus communicate with each other. The signal bus adapter of the terminal is directly connected to a star distributor via a partial transmission path of the signal bus. The star distributor is a signal bus adapter of a call control and connected via a partial transmission path of the signal bus directly to a signal bus adapter of a call control, or the star distributor is two partial transmission paths of the signal bus directly with two signal Bus adapters connected by two call controllers.

The advantage of the invention is that two call controls are provided, which are both directly addressable from a terminal via signal bus adapter in a signal bus, whereby the availability of the elevator system is guaranteed even in case of failure of a call control or elevator control , A signal bus is understood as a communication connection in which all subscribers of a communication can be addressed directly via a single transmission path, be it by electric current, light or radio. The terminal can thus transmit a driving request with information about the input floor and the destination floor of a passenger to the addresses of two call controls. On the transmission data packets from sending participants to receiving subscribers are addressed directly addressed. A star distributor connects several partial transmission paths. The star distributor is either itself a signal bus adapter of a call control and connected via a partial transmission path with a signal bus adapter call control or he is connected via two partial transmission paths with two signal bus adapters of two call controllers , If one of the call controls or one of the elevator controls fails, then it is the Communication in the signal bus between the terminal and the non-failed call control not affected.

Advantageous developments of the invention are described in the dependent claims.

Advantageously, at least one database of the elevator installation has at least one passenger profile and / or at least one elevator profile. The star distributor is a signal bus adapter of the database or it is connected via a partial transmission path of the signal bus directly to a signal bus adapter of the database. Advantageously, at least one security database of the elevator installation has at least one replicated passenger profile of the database and / or at least one replicated elevator profile of the database. The star distributor is a signal bus adapter of the backup database or it is connected via a partial transmission path of the signal bus directly to a signal bus adapter of the backup database.

As a further advantage, not only call controls of the elevator installation are thus redundantly designed, but also a database with passenger profile and / or elevator profile is redundantly designed by a backup database. The terminal can thus transmit a detected identification code of a passenger directly to the address of a database, and in the event of failure of the database directly to the address of a backup database to receive in response an indication to a predefined floor of the passenger. Again, this is the

Star distributor either itself a signal bus adapter of the database or a signal bus adapter of the backup database or the star distributor is connected via a partial transmission path with a signal bus adapter of the database or a signal bus adapter backup database.

Advantageously, the partial transmission path of the signal bus is a LON bus or an Ethernet network. This is an advantage as a LON bus is cheaper to purchase than an Ethernet network. An Ethernet network, on the other hand, is more cost-effective to maintain, being very common and commonly known to maintenance technicians.

Advantageously, the partial transmission path of the signal bus from the signal bus adapter of the terminal to a star distributor is a LON bus, while the partial transmission path of the signal bus from the star distributor to a signal bus adapter of a call control and / or the Database and / or the backup database is an Ethernet network.

This has the advantage that different signal buses can be used in combination. The first signal bus uses a cost-effective, robust LON bus with a long transmission path of up to 900 m, while the second signal bus uses a high-speed Ethernet network with a short transmission distance of around 90 m for twisted-pair copper cables. Thus, especially in large buildings, a large number of terminals arranged on the floors can be addressed directly in a LON bus, while the call controllers, the database and the backup database are located directly next to the elevator controls in a machine room via an Ethernet network to be addressed.

Advantageously, the signal bus has a plurality of star distributors. Advantageously, several star distributors are directly connected to one another in a horizontal hierarchical level of the signal bus via a plurality of partial transmission paths of the signal bus. Advantageously, several star distributors in several vertical hierarchical levels of the signal bus are connected directly to each other via partial transmission paths of the signal bus.

This is an advantage as elevator systems with several elevators have very high availability. When the signal bus adapters of six call controls for six lifts operated in parallel in two vertical hierarchical levels of the signal Buses are directly addressable via four star distributor for a terminal, so the failure of an elevator with a call control and an elevator control to a loss of 1/6 or 16% of the capacity of the elevator system. However, the availability of the elevator system remains high, because the terminal can continue to transmit in the signal bus a driving request with details of the input floor and the destination floor of a passenger to the addresses of five non-failed call controls.

Advantageously, each star distributor has a plurality of signal bus adapters and a plurality of partial transmission paths of the signal bus are connected to the signal bus adapters of the star distributor.

This has the advantage that a star distributor that operates only on the deepest physical layer of the Open Systems Interconnection (OSI) reference model quickly transmits data packets with a low latency of less than 10 ^{~ 6} sec.

Advantageously, the star distributor has at least four signal bus adapters.

This has the further advantage that the nesting depth of the horizontal and vertical hierarchical levels can be kept low, since each star distributor has a larger number of signal bus adapters.

Advantageously, given a given number of signal bus adapters per star distributor, all sub-transmission paths are connected to signal bus adapters of the star distributors such that the transmission path from the signal bus adapter of the terminal to a signal bus adapter is the farthest remote call control is bridged with a minimum of star distributors. Advantageously, given a given number of signal bus adapters per star distributor, all sub-transmission paths are connected to signal bus adapters of the star distributors such that the transmission path from the signal bus adapter of the terminal to a signal bus adapter is the farthest remote database with is bridged to a minimum of star distributors. Advantageously, given a given number of signal bus adapters per star distributor, all sub-transmission paths are connected to signal bus adapters of the star distributors such that the transmission path from the signal bus adapter of the terminal to a signal bus adapter is the farthest remote backup database is bridged with a minimum of star distributors.

This is of particular advantage since in this way the signal bus can be flexibly adapted to a wide variety of given designs of an elevator installation in a building. By placing several star distributors with multiple signal bus adapters per star distributor, the transmission path of communication with a minimum of star distributors is realized in a clear and cost-effective manner.

Advantageously, the star distributor is a switch with at least six signal bus adapters for several partial transmission paths. The switch evaluates at least one address information of a data packet received via a first partial transmission path from a signal bus adapter and transmits the data packet to a signal bus adapter via a further partial transmission path.

This has the advantage that in large elevator systems with more than sixteen elevators, the number of star distributors is kept low. A switch with eight or sixteen signal bus adapters operates on a higher layer of the OSI reference model and evaluates the address information of a data packet received over a first sub-transmission path. The switch sends the data packet according to an address table via another sub-transmission path. Compared with a star distributor which only works on the deepest physical layer of the OSI reference model, the bandwidth in the signal bus is thus increased since received data packets are no longer sent to all subscribers in all connected sub-transmission paths. However, the evaluation of the address information increases the latency of the switch by a factor of 10 compared to a star splitter that only works on the deepest physical layer of the OSI reference model.

Advantageously, a call control is arranged on a first plug-in card and at least one signal bus adapter is arranged on a second plug-in card. The first plug-in card and the second plug-in card are connected directly to one another to form a printed circuit board.

This is advantageous because it controls the diversity of the signal buses by arranging the call control and the call control signal bus adapter for communication with the terminal on different plug-in cards. In this way, call control can be produced uniformly and inexpensively in large quantities on a first plug-in card and, depending on the signal bus required for communication with the terminal, connect directly to a printed circuit board with a corresponding signal bus adapter of a second plug-in card.

Advantageously, at least one database of the elevator installation with at least one passenger profile and / or at least one elevator profile with the call control is arranged on the first plug-in card, or at least one database of the

Elevator installation with at least one passenger profile and / or at least one elevator profile is arranged on a further first plug-in card.

This has the advantage that on a first plug-in card not only the call control, but also a database in large

Quantities uniform and inexpensive to produce.

Advantageously, the first plug-in card and the second plug-in card are reversibly connected to one another via at least one first plug connection.

This has the advantage that the first and second plug-in card can be connected to one another quickly and easily without soldering and can also be released again. In case of defect of a printed circuit board can be so replace the defective plug-in card easily and quickly. Thus, a maintenance technician can easily and quickly take a first plug-in card with call control in the event of a defect in a printed circuit board of a lift installation and take a second plug-in card with the elevator-specific signal bus adapter from a second warehouse and ad hoc this via the first plug connection Connect circuit board.

Advantageously, the terminal transmits a drive request to addresses of signal bus adapters of the call controllers. A first call control generates travel orders for a first elevator control for the drive request, a second call control generates travel orders for a second elevator control for the drive request. The call controls transmit information on the driving orders as Zielrufofferten via the signal bus to an address of the signal bus adapter of the requesting terminal. The terminal selects a destination call offer and transmits a selection confirmation of the destination call offer via the signal bus to the address of the signal bus adapter of the call control of the selected destination call. The call control of the selected Zielrufofferte transmits for the selection confirmation of the Zielrufofferte driving orders via at least one serial bus to an address of at least one elevator control of the elevator system. Advantageously, at least one serial bus adapter for the serial bus is arranged on the second plug-in card. Advantageously, at least one serial bus adapter for the serial bus is arranged on a third plug-in card. The second plug-in card and the third plug-in card are connected directly to each other.

This is also advantageous because not only the diversity of the signal buses, but also the variety of serial buses is dominated by dedicated plug-in cards. As elevator systems are long-lived capital goods, it is quite common that they are in operation for 30 or more years. As industry standards for serial buses change much faster, a large variety of serial buses inevitably evolve over time. Advantageously, the second plug-in card and the third plug-in card are reversibly connected to one another via at least one second plug connection.

This also has the advantage that the second and third plug-in card can be connected to one another quickly and easily without soldering and can also be released again. If a plug-in card is defective, the defective plug-in card can be easily and quickly replaced.

Advantageously, at least one electrical power connection is arranged on the second plug-in card. The electrical power supply supplies all components of the circuit board with electric current. Advantageously, the electrical power connection is integrated in at least one signal bus adapter for the signal bus and / or in at least one serial bus adapter for the serial bus. Advantageously, the second plug-in card has several electrical power connections.

This is of practical advantage since the second plug-in card thus not only enables the communication of the call control or database in the signal bus but also provides the electrical power supply. Also, the availability of the elevator system is increased since the printed circuit board is supplied redundantly, for example via an electrical power connection from the elevator control and via the signal bus adapter from the signal bus with electrical power. In case of power failure of the elevator control, the signal bus adapter is thus still supplied via the signal bus with electrical power, and the communication between the terminal and the call controls in the signal bus is still possible.

Advantageously, exactly one call control is connected via at least one serial bus to exactly one elevator control.

This is advantageous because it does not affect the availability of the elevator system with several lifts by the call control. Per elevator exactly one elevator control and exactly one call control are provided. Advantageously, the elevator controls are connected to each other via serial bus adapters in at least one second serial bus. Advantageously, the elevator controls in the second serial bus transmit safety-relevant information such as a fire alarm and / or an earthquake alarm and / or a power failure alarm and / or an elevator failure alarm.

This has the advantage that the elevator controls exchange safety-relevant information with each other independently of the call controls. The safety-relevant information concerns the safety of the passengers. In the event of a fire or an earthquake, the elevators travel to safe floors, regardless of the driving orders of the call controls, and open the lift doors so that the passengers can leave the elevator cars.

Advantageously, an existing elevator system is retrofitted to an elevator system according to the invention by installing at least one terminal, whereupon at least two call controls are installed on at least one first plug-in card of at least one printed circuit board. Now, the terminal is connected via at least one signal bus with at least one signal bus adapter on a second card and / or third card stretch of the circuit board and each call control is connected to at least one serial bus adapter on a second card and / or a third Plug-in card connected via at least one serial bus with at least one existing elevator control.

This is advantageous because a terminal is installed quickly and easily, for example by screwing on a building wall, since the circuit board is installed just as easily and quickly, for example by inserting into an elevator control and since the connection to the signal bus and serial bus is done quickly and easily. Advantageously, given a given number of signal bus adapters per star distributor, all partial transmission paths are connected to signal bus adapters of the star distributors in such a way that the transmission path from the signal bus adapter of the terminal to a signal bus adapter is the farthest remote call control is bridged with a minimum of star distributors. Advantageously, at least one database of the elevator installation with at least one passenger profile and / or at least one elevator profile is installed on at least one first plug-in card of at least one printed circuit board. Given a given number of signal bus adapters per star splitter, all sub-transmission paths are connected to signal bus adapters of the star distributors such that the transmission path from the signal bus adapter of the terminal to a signal bus adapter of a farthest database is bridged with a minimum of star distributors. Advantageously, at least one backup database of the elevator installation with at least one replicated passenger profile of the database and / or at least one replicated elevator profile of the database is installed on at least one first plug-in card of at least one printed circuit board. For a given number of signal-to-bus adapters per star distributor, all sub-transmission paths are connected to signal-to-bus adapters of the star distributors such that the transmission path from the signal bus adapter of the terminal to a signal-to-bus adapter of the

Farthest backup database is bridged with a minimum of star splitter.

Advantageously, the elevator controls are interconnected via at least one second serial bus and the lift controllers transmit safety-relevant information such as a fire alarm and / or an earthquake alarm and / or a power failure alarm and / or an elevator failure alarm via the second serial bus.

Advantageously, a computer program product comprises at least one computer program means which is suitable for the method for operating an elevator installation thereby realize that at least one method step is carried out when the computer program means is loaded into at least one processor at least one terminal or at least one call control or at least one database or at least one backup database of the elevator installation or at least one elevator control of the elevator installation. A computer-readable data store includes such a computer program product.

The opening and closing of the elevator door 10.1, 10.1 ', 10.2, 10.2', 10.3, 10.3 'takes place via the door drive 16, 16'. The door drive 16, 16 'is usually arranged on the elevator car 12, 12' and actuates at least one car door 11, 11 '. During a floor stop, the car door 11, 11 'is with the elevator doors

10.1, 10.1 ', 10.2, 10.2', 10.3, 10.3 'can be brought into operative connection by mechanical coupling such that the opening and closing of the car door 11 and the elevator doors 10.1, 10.1',

According to FIG. 1, at least one terminal 9.1, 9.1 ', 9.2, 9.2',

9.3, 9.3 'near an elevator door 10.1, 10.1', 10.2, 10.2 ', 10.3, 10.3' arranged. The terminal 9.1, 9.1 ', 9.2, 9.2', 9.3, 9.3 ', for example, mounted on a building wall or is isolated in a room in front of an elevator door 10.1, 10.1', 10.2, 10.2 ', 10.3, 10.3'. The terminal 9.1, 9.1 ', 9.2, 9.2', 9.3, 9.3 'communicates in at least one local radio network 5 with at least one mobile identification device 6. For this, the terminal has .1, 9.1', 9.2, 9.2 ', 9.3, 9.3' over at least one transmitting unit and at least one receiving unit. The mobile identification device 6 is, for example, a passenger-carried Radio Frequency Identification (RFID) card with at least one coil, at least one data memory and at least one processor.

The radio frequency used by the terminal .1, 9.1 ', 9.2, 9.2', 9.3, 9.3 'is, for example, 125 kHz, 13.56 MHz, 2.45 GHz, etc. The mobile identification device 6 inductively receives energy from the electromagnetic field of the transmitting unit via its coil on and is energetically activated. The energetic activation takes place automatically as soon as the mobile identification device 6 is within the range of the electromagnetic field of a few centimeters to one meter of the transmitting unit.

Processor stored in the data store destination floor code and / or identification code, via the coil to the Receiving unit is sent. The energetic activation of the mobile identification device and the sending of the destination floor code or of the identification code to the transmitting and receiving unit takes place without contact. The receiving unit receives the transmitted destination floor code or identification code and prepares it electronically. For this purpose, at least computer program means can be loaded from the computer-readable data memory into the processor, which recognizes the transmitted destination floor code or identification code. The terminal 9.1, 9.1 ', 9.2, 9.2', 9.3, 9.3 'has at least one input means such as a button or a touch-sensitive screen.

The signal bus 5 'is, for example, a LON bus with LON protocol, an Ethernet network with the Transmission Control Protocol / Internet Protocol (TCP / IP), an Attached Resources Computer Network (ARCNET), etc. Bus adapter 5.1, 5.1 ', 5.1'', 5. I ¹ ''is a standardized signal bus adapter such as WAGO 734, Registered Jack 45 (RJ45), etc. The terminal 9.1, 9.1', 9.2, 9.2 ', 9.3, 9.3' comprises at least one computer-readable data memory and at least one processor. At least one computer program means is loadable from the computer readable data memory into the processor and performs the communication. Especially in large buildings with many floors and lifts with multiple elevators, a large number of terminals can be installed. A building with 60 floors and eight elevators can have four terminals per floor or a total of 240 terminals. The length of the signal bus 5 'from the terminals 9.1, 9.1', 9.2, 9.2 ', 9.3, 9.3' to Database 8 and call control 7, 7a, 7b, 7 ', 7a', 7b 'can be considerable. In the case of a LON bus, a length of a single transmission path is about 900m for communication and 90m for an Ethernet network. The person skilled in the art can therefore provide star distributors in order to functionally relate to partial transmission paths of the signal bus 5 '.

The recognized identification code is from the terminal 9.1, 9.1 ', 9.2, 9.2', 9.3, 9.3 'via the signal bus 5' to the address of the signal bus adapter 5.1, 5.1 ', 5.1'', 5.1 ¹ ''the database 8 transmitted. The identification code is used together with the

Address of the identification code transmitting terminals 9.1, 9.1 ', 9.2, 9.2', 9.3, 9.3 'transmitted. The database 8 has at least one processor and at least one computer-readable data memory and at least one electrical power supply. From the computer-readable data memory, at least one computer program means is loaded into the processor and executed.

The database 8 carries at least one passenger profile for at least one passenger with information such as at least one predefined destination floor as well as at least one access authorization to floors S1, S2, S3 and rooms of the building. The predefined destination floor can change over time for one and the same input floor. For example, the destination floor changes according to the programmed habits of the passenger and is different for one and the same input floor at noon and in the evening. The access authorization is temporally and / or spatially zoned. For example, the passenger only has access to certain zones of the building at certain times. Furthermore, at least one predefined destination floor is maintained in the passenger profile for at least one input floor.
