Definitions
- the present invention relates to a method for communicating with an elevator system by means of a mobile terminal and such an elevator system or such a mobile terminal.
- An elevator system is used to transport people within buildings, with an elevator car being moved vertically between different floors in an elevator shaft.
- the elevator system In order to ensure the safety of passengers or service staff, the elevator system must be maintained regularly.
- the elevator system is put into a maintenance mode in which automatic operation of the elevator car is blocked or the elevator car is only allowed to move at a walking speed using manual control.
- the invention is based on the object of ensuring the operational safety of an elevator system not only during maintenance work, but also afterwards when the elevator system is switched back to normal operation.
- a method for communicating with an elevator system by means of a mobile terminal is provided.
- the procedure may include the following steps:
- a communication connection between the elevator system and the mobile terminal can thus be created using optical transmission technology.
- light is modulated with a modulation signal (light signal).
- the light can be varied in amplitude, phase and polarization.
- the detected coded light signal or the data of the detected coded light signal is advantageously transmitted to the elevator system.
- the control panel is, for example, a floor panel, also called Called LOP (Lobby Operation Panel). Because the mobile terminal receives a light signal generated by the elevator system and sends this light signal back to the elevator system either directly or in a modified form, such as in digital data packets, via a feedback path as feedback or confirmation, the elevator system will then take note that that there is a communication connection via the light signal between it and the mobile terminal.
- the elevator system can therefore be used reliably in maintenance mode because, on the one hand, it is possible to carry out a prescribed (complex) check-in process with the help of the mobile terminal; on the other hand, the current position of a service personnel can be easily determined.
- the elevator system can also be safely put into normal operation from maintenance operations without the possibility of a dangerous movement of the elevator car when personnel are present in the shaft or, under certain circumstances, with a potential risk if a check-out process is carried out using the mobile terminal is.
- the mobile terminal can be authenticated by the elevator system if the request from the mobile terminal contains its identity, for example.
- the detection of the coded light signal is pre-checked in such a way that before the light signal is generated, a coded test light signal is generated using the control panel of the mobile terminal, and the coded test light signal is detected by the mobile terminal.
- the test light signal can also be transmitted to the elevator system directly or in a modified form (e.g. data or data packages).
- the mobile terminal can also decode the coded test light signal. Transmitting the detected test light signal confirms that the coded test light signal was received by the mobile terminal without any problems. This means that there is secure communication in this way between the mobile terminal and the elevator system.
- the detected test light signal or its data can be transmitted with the addition of a test value, and / or the detected light signal or its data can be transmitted can also be done with the test value.
- the check value can be used to detect an error that may have occurred while saving or transferring data.
- the test value can be designed in such a way that errors in data transmission, such as those caused by noise on a line or a Wired or wireless network causes have a high probability of being detected.
- the test value can be developed to protect against common errors in communication in order to ensure the integrity of the transmitted data or signals quickly and appropriately.
- the coded light signal and/or the coded test light signal are generated in the form of a temporal light signal sequence.
- the light signal can be coded in the time domain, e.g. like Morse code.
- the control panel it is not necessary for the control panel to be equipped with a screen to display a light signal in graphic form.
- the corresponding information can be transmitted in the form of light signal sequences.
- a control panel of an elevator system does not include a screen, if at all, then the control panel as a COP (Car Operation Panel) is usually located in an elevator car.
- COP Car Operation Panel
- the position of the mobile terminal can be determined through communication with the elevator system. This means that the current position of a service personnel can also be easily determined. Not only can it be determined whether a technician is outside an elevator shaft, but it can also be determined which floor the technician is currently on because the individual control panels can be individually identified.
- a mobile/portable terminal for an elevator system is provided.
- a mobile terminal is, for example, a mobile telephone (smartphone), a laptop, a tablet computer, or a PDA (Personal Digital Assistant), etc.
- the mobile terminal is designed to communicate with the elevator system in such a way that the mobile terminal sends a request to the elevator system sends; - the mobile terminal detects a coded light signal when the coded light signal is generated in response to the request by a control panel which is arranged outside an elevator shaft of the elevator system,
- the mobile terminal confirms the detection of the coded light signal to the elevator system
- the mobile terminal is authorized by the elevator system to communicate with the elevator system.
- the mobile terminal of the elevator system can transmit the detected coded light signal or its data to confirm the detection of the coded light signal.
- the coded light signal of the elevator system can be sent back directly or in a modified form as feedback or confirmation, so that the elevator system is informed that a communication connection via the light signal exists between it and the mobile terminal.
- the detection of the coded light signal can be pre-tested in such a way that the mobile terminal detects a coded test light signal, the test light signal being generated before the light signal by means of the control panel in response to this request, and the mobile terminal of the elevator system the detected test light signal or its data is transmitted.
- the detected test light signal or its data and/or the detected light signal or its data are transmitted with the addition of a test value. This makes it possible to monitor whether accidental errors occurred when transmitting or storing the test light signal.
- a maintenance inspection work for the elevator system can be controlled and/or started by means of the mobile terminal.
- a service personnel can, for example, easily move an elevator car using his smartphone or stop it at a desired location.
- the service staff can specify a desired stop floor or any stop position using the mobile terminal. That's why the service staff must during Maintenance work should not always be on the roof of the elevator car or in the shaft pit, but rather in the elevator car or outside the shaft.
- an elevator system with a control panel wherein the control panel is arranged outside an elevator shaft of the elevator system.
- the elevator system can communicate with a mobile terminal in such a way that the elevator system receives a request from the mobile terminal from the mobile terminal; a coded light signal is generated by a control panel in response to the request and then detected by the mobile terminal; the elevator system receives confirmation of the detection of the coded light signal; the elevator system authorizes the mobile terminal to communicate with the elevator system.
- the control panel does not need to be equipped with a screen.
- the control panel can, for example, be a simple control panel with only one or two call buttons (up and down call buttons). It is known that light emitting diodes (LEDs) are used as a light source in such keys to illuminate a key to display an arrow symbol.
- the call button or the two call buttons are illuminated for a specific time within a predetermined time period, for example, so that the control panel can emit a temporal light signal sequence.
- the illumination of each key can last independently for different lengths of time. This means that the light signal can be coded in the time domain, e.g. like Morse code.
- the detected coded light signal or its data can be transmitted to the elevator system as confirmation of the detection of the coded light signal.
- the detection of the coded light signal can be pre-tested in such a way that a coded test light signal is generated in front of the light signal by means of the control panel in response to this request and is then detected by the mobile terminal, the mobile terminal of the elevator system receives the detected test light signal or whose data is transmitted.
- the detected test light signal or its data and/or the detected one is transmitted Light signal or its data with the addition of a test value to monitor whether accidental errors have occurred when transmitting the test light signal.
- a computer program may be given that includes instructions that cause a processor, such as a processor of the mobile terminal, to carry out the method specified above upon execution of the computer program by the processor.
- the computer program can be stored on a computer-readable medium (USB, server, cloud, or a storage unit of the mobile terminal).
- FIG 4 Graphical representation of the method according to the invention with a preliminary test.
- Fig. l illustrates details of an elevator system 1 according to the invention and a mobile terminal 5 according to the invention.
- An elevator car 7 can travel between different floors in an elevator shaft 3.
- a shaft door 6 is provided on each floor.
- a control panel 2, such as an LOP, is arranged next to the shaft door 6.
- a technician 9 can control or move the elevator car 7 up and down during inspection operation through a mobile terminal 5, for example a smartphone, so that he can easily stop the elevator car 7 at a desired floor or location.
- the mobile terminal 5 can be connected to the controller of the elevator system 1 wirelessly or by wire.
- the necessary security measures e.g.
- a checklist) or a check-in/check-out process can be carried out using the mobile terminal 5 before switching the elevator system 1 between maintenance operation and normal operation.
- the technician 9 can receive all the necessary information about the mobile terminal 5 when the mobile terminal 5 communicates with the elevator system 1.
- the mobile terminal 5 can also be connected to the Internet.
- the elevator system 1 can also be informed about the presence or current position of the technician 9. In addition to determining whether a technician 9 is outside or inside the elevator shaft 3, depending on the position of a control panel 2, it can be determined which floor the technician is now on, because the control panel 2 as LOP can designate the specific floor. A potentially dangerous scenario can therefore be avoided if possible.
- the elevator system 1 can therefore be reliably used in maintenance mode or back into normal operation.
- the elevator system 1 can communicate with the mobile terminal 5 by the control panel 2 generating a light signal sequence and the mobile terminal 5 detecting this light signal sequence.
- Fig. 2 shows communication between the elevator system 1 and the mobile terminal 5.
- the mobile terminal 5 is connected to a controller 8 of the elevator system 1 via a LAN (Local Area Network). If maintenance work for the elevator system 1 needs to be started or completed, a corresponding check-in/check-out process must be carried out.
- the mobile terminal 5 first sends a request via application software (eg app) to a controller 8 of the elevator system 1, whereby the request can contain an identity of the mobile terminal 5.
- the elevator system 1 can thus authenticate the mobile terminal 5.
- the control panel 2 then generates a coded light signal.
- the control panel 2 includes, for example, two arrow keys, each key having an LED.
- the mobile terminal 5 receives the light signal and converts it into data that can be processed by the computer processor.
- the mobile terminal 5 then transmits the detected light signal to the controller 8 in the form of the converted data.
- the transmission of the light signal is added with a test value. By checking whether the test value has been changed, a change in the transmitted light signal can be experienced. If the test value is not changed, it means that the light signal was correctly detected by the mobile terminal 5.
- the controller 10 can authorize the mobile terminal 5 to communicate with the elevator system 1 or to be able to access the elevator system 1.
- FIG. 3 shows a method according to the invention for communicating with the elevator system 1 using the mobile terminal 5. It is assumed that maintenance work should be carried out for an elevator system 1 shown in Fig. l. The following steps, numbered “S”, must therefore be carried out:
- the elevator system 1 authenticates the mobile terminal 5 if the request contains an identity of the mobile terminal 5;
- the mobile terminal 5 sends the elevator system 1 the data to transmit the detected coded light signal so that this detection is confirmed;
- the data is added with a test value, for example when saving or transmitting. Accordingly, the method will be as shown in Fig. 4, where the first two steps Sl 'and S2' are the same as the first two steps of the method in Fig. 3:
- S5' The mobile terminal 5 sends a controller 8 of the elevator system 1 the data with a test value added, whereby the controller 8 is informed of this test value;
- S6' The controller 8 instructs the control panel 2 to generate a new light signal;
- the mobile terminal 5 sends the data of the detected light signal to the controller 8 again with the addition of the test value;
- embodiments of the method presented here allow a safety hazard in an elevator shaft to be avoided at an early stage.
