In an elevator system, passengers are transported in a building. From the EP0699617A1 For example, an elevator installation with a recognition device for recognizing a passenger's identification code is known. In the access area to the elevator doors of the elevator installation, a detection device is stationary on each floor of the building. The detection device emits an electromagnetic field permanently. As soon as an information transmitter carried by the passenger gets into the electromagnetic field of a recognition device, the information transmitter is woken up as a result of the electromagnetic field and sends the data stored thereon, such as an identification code, to the recognition device. The identified identification code is assigned a stored predefined destination floor information and this destination floor information is transmitted to the elevator control. The elevator controller makes a destination call for the passenger with this destination floor information. An elevator car is moved to the floor of the passenger, the elevator door is opened, the passenger climbs the elevator car and is transported to the destination floor.

The executed application computer program means outputs the elevator state information 19 and / or the elevator call information 20 on the output device 60.

At least one reporting device 5 is mounted near the elevator installation 1. For example, the elevator installation 1 according to Fig. 1 on the top floor S20 a reporting device 520 and on the other floors S01, S02, ... S18, S19 a plurality of signaling devices 501, 501 ', 502, 502', ... 518, 518 ', 519, 519' on, while the elevator installation 1 according to Fig. 4 on each floor S01, S02, ... S06, S05, S06 has a plurality of signaling devices 501, 501 ', 502, 502', ... 506, 506 ', 507, 507', 508, 508 '. As in the embodiments according to Fig. 2 and 4 a message device 502, 502 'may be shown near and / or at an elevator door 21 or remote from elevator doors 200, 201 be installed on a floor S02. The reporting device 5 is, for example, an RFID transponder having at least one computer-readable data memory and at least one processor and at least one coil 56.

The mobile device 6 has a further transceiver 65 for communication via radio network with the reporting device 5. The communication between the reporting device 5 and the further transceiver 65 may be bidirectional. From the computer-readable data memory of the mobile device 6 at least one communication computer program means is loaded into the processor and executed. The communication computer program means controls the transmission and reception of the further transceiver 65. The communication between the further transceiver 65 and the reporting device 5 tracks in a near field radio network of up to one meter reception range at radio frequencies of, for example, 125 kHz, 13.56 MHz, 2.46 GHz, etc .. To this shows Fig. 7 a flowchart of a part of the method for operating an elevator system. 1

In method step A , the mobile device 6 is brought into the reception range of the reporting device 5. The signaling device 5 inductively receives energy from an electromagnetic field of the further transceiver 65 via the coil 56 and is energetically activated via at least one activation signal 10. The energetic activation takes place automatically, as soon as the further transceiver 65 is in the reception range of the coil 56 of the reporting device 5 from a few centimeters to a meter.

As soon as the signaling device 5 is energetically activated, in process step B the processor of the reporting device 5 reads at least one network address 11 of the recognition device 3 stored in the computer-readable data memory, which network address 11 is sent via the coil 56 to the further transceiver 65 , The energetic activation of the message device 5 and the transmission of the network address 11 of the recognition device 3 to the other transceiver 65 is contactless. The further transceiver 65 receives the transmitted network address 11 of the recognition device 3.

In method step C, the mobile device 6 uses the received network address 11 of the device 3 and sends to the transmitting-receiving device 63 at least an identification code 12 3. The device 3 receives on the received network address 11 of the recognition device the identification code 12th

In method step D , the received identification code 12 is recognized by the recognition device 3. For this purpose, at least one recognition computer program means is loaded from the computer-readable data memory into the processor. The recognition computer program means controls the verification of the identification code 12 by the recognition device 3. Further, passenger data from the computer-readable data memory are loaded into the processor and compared with the received identification code 12. For a positively verified identification code 12, at least one passenger detection signal 13 is transmitted to the elevator control 4. For a negative verified identification code 12, at least one alarm signal 14 is sent. Subsequently, at least one alarm action is performed in method step E. The alarm action consists for example in a notification by the alarm signal 14 of a security service and / or the police.

In method step F , at least one elevator call 15 is made by the elevator control 4 for a received passenger identification signal 13 or a plurality of possible destination floors are determined. For example, the elevator call 15 is at least one destination call comprising call information to a boarding floor and a destination floor of a passenger. But it is also possible that the elevator call 15 is a combination of at least one landing call and at least one car call, wherein the Floor call includes information about a boarding floor and the car call includes information about a destination floor.

The elevator control 4 controls, via the control computer program means, the process of the elevator car 2 via the elevator drive and the opening and closing of the elevator door via the door drive. Thus, in process step G, the elevator car 2 is moved by the elevator drive into the boarding floor, the elevator door is opened by the door drive and the passenger can enter the elevator car 2. Thereafter, the door drive closes the elevator door and the elevator car 1 is moved by the elevator drive into the destination floor, where the door drive opens the elevator door and the passenger leaves the elevator car 2.

Regardless of all the previous method steps B to G, in step H the transceiver 63 is brought into the reception range of the radio network of the elevator installation 4, for example in which a passenger carries the mobile device 6 into the building of the elevator installation 4. The method steps A and H can thus take place in a small time offset. The transceiver 63 reports with at least one request signal 16 in the radio network.

In method step I , a network address of the transceiver 63 is determined by the coordination computer program means or the transceiver 63 is assigned a network address. The network address of the transceiver 63 is entered in the connection table and is available to the recognition device 3.

In method step J , the recognition device 3 transmits at least one contact acquisition signal 17 to the network address of the transceiver 63. With the contact acquisition signal 17, the mobile device 6 is asked whether at least one application computer program means is stored in its computer-readable data memory. The transceiver 63 receives the contact-receiving signal and checks in the method step K, whether an application computer program means is stored in the computer-readable data memory of the mobile device 6. If this is not the case, the transceiver 63 transmits at least one denial signal 18, whereupon in step L, the recognition device 3 sends at least one application computer program means to the transceiver 63 which stores the received application computer program means in the computer readable data memory of the mobile device 6 stores.

If an application computer program means stored in the computer-readable data memory of the mobile device 6, it is loaded in process step M in the processor of the mobile device 6 and executed. The application computer program means controls the output device 60 of the mobile device 6. The recognition device 3 transmits at least one elevator state information 19 and / or at least one elevator call information 20 to the transceiver 63. The transceiver 63 receives the elevator state information 19 and / or the elevator call information 20. The application computer program means outputs the received elevator state information 19 and or elevator call information 20 on the output device 60. The same elevator state information 19 and the same elevator call information 20 can also be output from the recognition device 3 on the output device 30 of the recognition device 3.

The passenger thus receives an elevator state information 19 and / or an elevator call information 20. The elevator state information 19 indicates to the passenger in which operating state the elevator installation 1 is located, to what degree the elevator installation 1 is available. For example, a positive elevator state information 19 is: "100% availability", negative elevator state information 18 is, for example, "70% availability, elevator B to 14:30 in maintenance". The elevator call information 20 gives the passenger a call acknowledgment and / or a route information. The route information informs the passenger, which elevator and / or which elevator car 2 is intended to move the passenger. Also, the route information guides the passenger from his current position to the elevator car 2. For example, an elevator call information 20 is: "Please go 10 meters to the left and take elevator C". The elevator call information 19 also indicates the boarding floor and the destination floor. Also, the elevator call information 20 indicates to the passenger the expected arrival time of the elevator car 2 on the boarding floor and / or the arrival time of the elevator car 2 on the destination floor. For example, an elevator call information 20 is: "The estimated arrival time of the elevator car is 12 seconds". The elevator state information 18 and the elevator call information 20 are permanently updated. The elevator state information 19 and the elevator call information 20 can be emitted optically and / or acoustically as more or less long flashing lights, sound sequences, signal sequences, etc.

In method step N , the passenger selects the destination floor again or selects a destination floor from several possible destination floors. For a change of the destination floor, the passenger selects the destination floor output as elevator call information 20 on the output device 30, 60 with the mobile device 6 and / or with the recognition device 3 and selects a destination floor again. In order to select a destination floor, the passenger receives as elevator call information 20 a plurality of possible destination floors determined by the elevator control 4 on the output device 30, 60. The passenger uses the mobile device 6 and / or the recognition device 3 to select a floor from the possible destination floors. The destination floor selected by the passenger or the destination floor selected by the passenger is transmitted to the elevator control 4 as a passenger confirmation signal 21. The elevator controller 4 receives the passenger confirmation signal 21 and the control computer program means corrects the elevator call 15. The control computer program means controls the process of the elevator car 2 into the destination floor newly selected by the passenger or into the destination floor selected by the passenger.

For example, the mobile device 6 and / or the recognition device 3 has at least one keyboard via which the passenger can change the destination floor by hand. The user enters the destination floor "18" by hand as a sequence of numbers "1" and "8" on the keyboard. The keyboard can also be a touch-sensitive touch screen. For example, the keypad operator can move a cursor over possible destination call indications and also, by keying the keyboard, stop the cursor over a destination call display and thus make a corresponding changed elevator call, which is transmitted to the elevator control 4 as a passenger confirmation signal 21.

Fig. 8 shows a retrofitted elevator installation 1 'of the invention. The existing elevator installation 1 'comprises at least one elevator car 2 and at least one existing elevator control 4'. The existing elevator control 4 'is connected via signal lines to the existing components of the existing elevator installation 1', such as elevator drive, elevator car 2, door drive, shaft information, etc. The existing elevator control 4 '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 control computer program means is loaded into the processor and executed. The control computer program means controls the process of the elevator car 2 via the elevator drive and the opening and closing of the elevator door via the door drive. From the shaft information, the existing elevator control 4 'receives information about the current position of the elevator car 2 in the elevator shaft. The signal lines are laid under plaster or hang in the elevator shaft.

To an existing elevator installation 1 'on an elevator system 1 according to the invention Fig. 1 to 6 to retrofit, at least one detection device 3 is installed in operative connection with the existing elevator control 4 'in one step. In a further step, at least one message device 5 installed near the elevator installation 1 '. Both the recognition device 3 and the reporting device 5 have been previously described, so that reference is made to these descriptions. In particular, the recognition device 3 communicates via radio network with the transceiver device 63 of the mobile device 6, and the reporting device 5 communicates via a radio network with the further transceiver device 65 of the mobile device 6.

For retrofitting the existing elevator installation 1 'to an elevator installation 1, at least one control 4' 'is installed in a further step. The controller 4 '' realizes the operative connection of the recognition device 3 with the existing elevator control 4 '. The controller 4 "is connected to the recognition device 3 via at least one signal line 401 and is connected to the existing elevator control 4 'via at least one further signal line 402. The controller 4 '' may be a standalone device, with its own housing, its own electrical power supply, its own processor, its own computer-readable data memory, its own network adapter, etc. The controller 4 '' can also be largely or completely integrated into the recognition device 3 , and, for example, as a printed circuit with its own processor, its own computer-readable data memory, its own network adapter, etc. pushed into the housing of the recognition device 3.

The signal lines 401, 402 are, for example, a data bus of a fixed network according to known and proven network protocols. Especially with older elevator systems 1 ', it is also possible that the signal lines 401, 402 are analog signal lines, which are connected to the existing elevator control 4' with inputs and outputs to floor terminals or elevator car terminals.

By placing the controller 4 "between the recognition device 3 and the existing elevator control 4 ', the recognition device 3 or the mobile device 6 indirectly communicates with the existing one by the controller 4" Elevator control 4 '. Thus, in method step D, at least one passenger detection signal 13 is transmitted to the controller 4 "by the recognition device 3 for a positively verified identification code 12. At least one elevator call 15 is transmitted to the existing elevator control 4 'by the controller 4 "for a received passenger identification signal 13.

In this way, the controller 4 '' in step F as elevator call 15 make at least one destination call or the controller 4 '' can act as elevator call 15 at least one landing call and at least one car call. For this purpose, the controller 4 "simulates an elevator call 15 in which, without actuating a key of a floor terminal or elevator car terminal, an elevator call signal is applied to the corresponding inputs and outputs of the existing elevator control 4 '. For a landing call from a boarding floor, the controller 4 "generates an elevator call signal at the entrance of the existing elevator control 4 'to the floor terminal of the boarding floor.
