Definitions
- the present invention relates to a method for processing a user request through a control system of an elevator installation and a control system for executing this method. Furthermore, the invention relates to a method for exchanging data between a mobile device and a control system of an elevator installation and a mobile device for executing this method. Furthermore, the invention relates to a computer program and a computer-readable medium for executing one of the methods or both methods, and a corresponding elevator system.
- Elevator cabins of elevator installations such as can be used to transport people or goods in multi-storey buildings, are usually operated using operating buttons that can be arranged in the cabin and/or in the building.
- a first aspect of the invention relates to a computer-implemented method for processing a user request by a control system of an elevator system, the elevator system comprising at least one elevator car that can be moved in an elevator shaft between different floors and the elevator car comprising at least one transmitter for emitting a detection signal, the method comprising: receiving the user request in the control system; the control system generating an identifier that enables the user request to be uniquely identified; Sending the identifier from the control system to a mobile device associated with the user request, wherein the mobile device is configured to receive the identifier from the control system and to send an acknowledgment of receipt, which confirms receipt of the identifier in the mobile device, to the control system when the mobile device receives the detection signal; when the acknowledgment of receipt is received in the control system: assigning the user request to a first category; otherwise: assigning the user request to a second category.
- the method can be executed automatically by one or more processors of the control system.
- the transmitter can be attached to the elevator car so that it can be moved in the elevator shaft together with the elevator car.
- the transmitter can be arranged inside and/or outside the elevator car.
- the detection signal can encode an ID of the transmitter, for example.
- the transmitter can be configured to transmit the detection signal with a specific signal strength and/or at specific transmission intervals.
- the transmitter can be configured to receive signals, for example from the control system and/or the mobile device. If the elevator system includes a number of elevator cars, each of the elevator cars can include at least one transmitter of its own, for example. In addition, such a transmitter or several such transmitters can be arranged at locations other than the elevator cars, for example in the elevator shaft or in the area of a door opening through which the elevator car is accessible from one of the floors.
- user requests from different categories can differ from one another in the manner in which they are processed or handled by the control system.
- the first category «desirable» include “legitimate” or “genuine” user requests
- the second category may include “undesirable,””invalid,” or “false” user requests.
- the identifier can be a random code or a cookie, for example.
- the acknowledgment of receipt can include the identifier itself, for example.
- the confirmation of receipt can be sent directly from the mobile device to the control system. Alternatively, the confirmation of receipt can be sent from the mobile device to the control system via the transmitter.
- the approach described above and below makes it possible to reliably identify and possibly track impermissible calls with which an elevator car is requested.
- the approach is based on the fact that the mobile device, which sends a call to the control system of the elevator installation via a wireless data communication link, is asked to prove its location, more precisely to prove that it is inside the elevator installation, for example inside an elevator shaft and/or an elevator car of the elevator system.
- This proof should be provided within a defined time window and can, for example, be triggered automatically on the basis of a detection of the mobile device, for example when the user enters the elevator car and the mobile device carried by the user is therefore within range of the transmitter of the elevator car, i. H. can receive and process the detection signal.
- desired calls can be distinguished from undesired calls.
- the latter can, for example, be continuously stored and updated in a corresponding list, which enables these calls to be tracked.
- Appropriate countermeasures can thus be taken in good time, for example by at least temporarily deactivating and/or ignoring further user requests from the relevant user or mobile device.
- Various escalation levels can be used here.
- the data communication network for such an authentication of the users does not have to cover the entire building, in particular not all floors of the building, but only requires the installation of suitable transmitters in a few selected sections of the building, namely the elevator cars.
- the number of elevator cars is significantly lower than the number of floors that are approached by the elevator cars.
- the installation costs can be significantly reduced compared to conventional concepts that require a very large area coverage.
- a second aspect of the invention relates to a computer-implemented method for exchanging data between a mobile device and a control system of an elevator system, the elevator system comprising at least one elevator car that can be moved between different floors in an elevator shaft, and the elevator car comprising at least one transmitter for emitting a detection signal
- the A method includes: generating, by the mobile device, a user request; Sending the user request from the mobile device to the control system, wherein the control system is configured to receive the user request from the mobile device, to generate an identifier that enables the user request to be uniquely identified, and to send the identifier to the mobile device associated with the user request; receiving the identifier in the mobile device; if the detection signal is received in the mobile device: the mobile device sends an acknowledgment of receipt confirming receipt of the identifier in the mobile device to the control system.
- the control system may be configured to process the user request in a method for processing a user request as described above and below.
- the method can be executed automatically by a processor of the mobile device.
- the method enables the mobile device to be reliably identified as that of a user who is actually at the location of the elevator system.
- the mobile device can, for example, automatically generate the confirmation of receipt and/or send it to the control system.
- the mobile device in response to upon receipt of the detection signal, first automatically generate a prompt that prompts the user of the mobile device for an input.
- the mobile device can then generate and/or send the confirmation of receipt to the control system in response to the user's input.
- the acknowledgment of receipt can only be sent as a result of an interaction with the (local) user. The security of the method can thus be further increased.
- a third aspect of the invention relates to a control system, comprising a processor that is configured to execute the method described above and below for processing a user request through a control system of an elevator installation. Characteristics of the control system can also be understood as characteristics of this method and vice versa.
- control system can include a central server that can receive and process user requests from different mobile devices.
- server can be configured to forward the user requests to a local control device for controlling an actuator of the respective elevator system, wherein the control device can also be part of the control system and can be connected to the server for data communication, for example via the Internet.
- the server It is possible for the server to communicate with the control devices of different elevator systems at different locations at the same time.
- the server can generate control signals directly from the user requests and forward them to the corresponding control device, which then converts the control signals accordingly.
- the server can be configured to forward the user requests to the appropriate control device.
- the forwarding can take place depending on the respective category of user requests.
- the user requests can also be sent directly, i. H. be received by the control device without going through the server.
- a fourth aspect of the invention relates to a mobile device, comprising a processor that is configured to execute the method described above and below for exchanging data between a mobile device and a control system of an elevator installation. Characteristics of the mobile device can also be understood as characteristics of this method and vice versa.
- a mobile device can be understood to mean a portable device with a processor, such as a smartphone, tablet, laptop or smartwatch.
- a special application can run on the mobile device, which is executed by the processor of the mobile device and enables the execution of the method for exchanging data described above and below.
- the mobile device can be connected to the control system and/or the transmitter wirelessly, for example via WLAN, Bluetooth and/or mobile radio, and/or via the Internet for data communication.
- control system and the mobile device can each comprise hardware and/or software modules.
- control system and the mobile device can each include a memory and data communication interfaces for data communication with peripheral devices.
- a fifth aspect of the invention relates to an elevator system.
- the elevator system includes: an elevator shaft; at least one elevator car, which can be moved between different floors in the elevator shaft and comprises at least one transmitter for emitting a detection signal; the control system as described above and below; and at least one mobile device as described above and below.
- the computer program includes instructions which, when the computer program is executed by the processor, cause a processor to carry out at least one of the methods described above and below.
- the computer-readable medium can be volatile or non-volatile data storage.
- the computer-readable medium can be a hard drive, USB memory device, RAM, ROM, EPROM, or flash memory.
- the computer-readable Medium can also be a download of a program code
- data communication network such as the Internet or a data cloud (cloud).
- the method for processing the user request may further include: storing the user request of the second category in a watch list; if the monitoring list exceeds a certain number of entries within a certain monitoring time: At least temporarily ignoring future user requests that are assigned to the same mobile device as the entries in the monitoring list. In this way, overloading of the data communication network, in which the control system is networked with the mobile device or mobile devices, can be avoided without completely blocking undesired user requests from the outset.
- the user request can only be assigned to the first category if the acknowledgment of receipt is received within a specific waiting time from a specific point in time since the identifier was generated. It can thus be avoided that the control system continuously waits for different acknowledgments of receipt, which can be associated with an increased computing effort. In addition, the security of the method against improper access can thus be increased.
- the waiting time can, for example, be less than 1 hour, in particular less than 10 minutes, preferably less than 1 minute.
- the user request can include position data that indicate a current location of the mobile device.
- the position data can then also be evaluated in order to assign the user request.
- the position data can, for example, have been determined by a position sensor that can be part of the mobile device, for example using a global navigation satellite system such as GPS or GLONASS. It is possible for the position data to be compared with reference data indicating possible plausible locations of the mobile device with respect to the elevator system. If the position data is a plausible location show, but no confirmation of receipt or the confirmation of receipt is not received in time, it can be concluded with high probability that the user request does not come from an actual, ie on-site user of the elevator system.
- the user request is only recognized as originating from an actual user if the position data indicate a plausible location and the acknowledgment of receipt is received (in good time).
- the position data can therefore be used for plausibility checks when categorizing the user request. The reliability of the method can thus be further increased.
- the method for processing the user request can also include: generating a control signal for driving actuators in the elevator system based on the user request, so that the elevator car is moved from a starting floor to a destination floor, with the user request being the starting floor and/or the destination floor Are defined.
- the user can select the starting floor and/or the destination floor in an application running on his mobile device (see also above).
- the user query that is generated by this application can then contain corresponding information about the selected starting or destination floor.
- the method can also include a step of selecting an elevator car from the plurality of elevator cars, it being possible for the control signal to be generated in order to move the selected elevator car from its current position to the starting floor and/or starting from the starting floor to proceed to the target floor.
- control signal is already generated before the time from which the acknowledgment of receipt is awaited.
- the elevator car can thus be moved in accordance with the desired destination floor even before the receipt of the confirmation of receipt.
- the transmitter can be configured to emit the detection signal within a defined range of at most 10 m, preferably at most 1 m. In this way it can be ensured that the mobile device only receives the detection signal when it is in the elevator car or in the immediate vicinity of the elevator car.
