  • US6446761 B1 describes an elevator system in which data is transmitted wirelessly between an elevator control, an elevator car, a counterweight and a plurality of elevator operator stations arranged on the floors.
  • terminals with transmitter-receiver units which have a relatively short range, are attached to the aforementioned elevator components.
  • the data is transmitted from the transmitting transceiver unit to the receiving transceiver unit via transceiver units located therebetween.
  • a transmitter-receiver unit currently arranged close to the elevator car is selected as an intermediate station depending on the known elevator car position.
  • US2006 / 0108181A1 describes an elevator system with an elevator control and a respective elevator control unit on each floor and in the elevator car.
  • the elevator operator units as well as the elevator controller are equipped with a piconet module, the piconet modules forming a wireless communication network through which each piconet module can receive and transmit transmitted information from all other piconet modules to all others.
  • the communications network allows information to be transmitted over a number of piconet modules, that is, over distances that exceed the range of a single piconet module.
  • the Piconet communications network also allows passengers to enter a lift call by means of a remote control device with piconet module, and that a maintenance professional can remotely check and influence the elevator control, for example by means of a PDA (personal digital assistant) with special module.
  • PDA personal digital assistant
  • US2012 / 0175196A1 describes a method for remote access to multiple subsystems of an elevator control system.
  • the method comprises, in particular, method steps which serve to detect at the beginning of a remote access whether a service device is already locally connected to the elevator control and is active.
  • EP 1415947 A1 discloses a device for remote maintenance and monitoring of an elevator system with at least one input for detecting first signals from an elevator controller and / or from a sensor having at least one output of second signals to a telecommunications network and at least one processor and a data memory, wherein in the data memory a Set of remote maintenance functions is stored and one of these remote maintenance functions can be activated. Data from a sensor or the elevator control are permanently transmitted via the telecommunication network to a service center.
  • EP 1282578 B1 describes a possibility for operating an elevator by means of a radiotelephone as a control unit.
  • the radio telephone which is also referred to as a mobile telephone or communication terminal, has a keypad provided as a data input unit and a display element provided as a data output unit, also called a display.
  • the mobile can wirelessly communicate with a mobile network, with voice and / or data being transferable. For transmission of voice and / or data, the mobile network can connect to other phones or with a terminal.
  • the terminal consists of a server system called a computer system, which has access to a memory with elevator-specific and / or general information.
  • the server is also connected to the elevator system by means of an interface.
  • Mobile phone, mobile network and terminal form a human / machine interface between the user and the elevator system.
  • a disadvantage of such methods is that for the wireless communication between a communication unit arranged on or in the elevator car of the elevator installation and a base station of the public mobile radio network, a large radio range and a high antenna performance are required so that secure communication can be ensured. On the one hand, this results in a relatively high energy consumption, and on the other hand, there is a considerable risk that electronic devices of the elevator installation will be disturbed in their function by electromagnetic fields. Frequently complex network protocols are used, which generate a high traffic load due to security requirements in the transmission of data. Thus, while a secure and reliable connection setup, reliable delivery of data packets and ensuring error-free transmission between the units involved in the communication can be guaranteed, the (communication) units additionally have a high energy consumption due to such network protocols.
  • the object of the invention is to propose a simple, energy-efficient communication method for the communication between an elevator car of an elevator installation and a service center remote from the elevator installation, which method of communication causes the lowest possible electromagnetic interference (electrosmog).

  • the stored data is transmitted from the mobile communication terminal via a public mobile radio network to the monitoring unit remote from the elevator installation.
  • the data is transmitted from the first communication unit as a function of at least one rule to the mobile communication terminal and stored there.
  • the data stored in the mobile communication terminal are transmitted from the mobile communication terminal via a public mobile network as a function of at least one further rule to the monitoring unit of the service center.
  • a defined data volume, a priority of the data, a security requirement criterion, a time, a time delay, a signal strength, a transmission time, an authentication or authorization of the mobile communication terminal or a proof can expediently be defined as at least one rule or at least one further rule in that the mobile communication terminal contains a specific program, a dependency on a request of the monitoring unit of the service center etc. is used.
  • the method can be used as the first communication network, ie as a communication link between the at least one unit and the first communication unit, a wired or a wireless communication network.
  • the method can be used as a mobile communication terminal, for example, a computer, an intelligent textile, a tablet computer (tablet PC), a mobile terminal, or an intelligent mobile terminal (smart phone), etc., wherein the mobile communication terminal via a wireless second communication network is connected to the first communication unit.

  • the at least one unit can be designed as a sensor unit, elevator control unit, actuator, elevator control unit, computer, mobile radio terminal, tablet computer, etc.
  • the data from the at least one unit can be transmitted to the first communication unit via a wireless first communication network when the elevator car with the first communication unit passes by or is in the vicinity of the sensor unit.
  • the radio range of the wireless first communication network can be chosen so that it corresponds approximately to the cross section of the elevator shaft. This ensures that the wireless first communication network for the transmission of data from the at least one unit to the first communication unit with relatively low radio range, d. H. can be performed with low power requirements.
  • an acceleration sensor for example, an acceleration sensor, a temperature sensor, an air pressure sensor, a current sensor, a force sensor, a magnetic field sensor, a gyroscope, a voltage sensor, a light sensor, a humidity sensor, a door contact unit, a security unit, a Weight sensor, a speed sensor, a position sensor, a switching unit, etc. are used.
  • the method is basically bidirectionally applicable.
  • the monitoring unit of the service center registered mobile communication terminals could be used to transmit data from the monitoring unit to the elevator system.
  • the monitoring unit transmits data to the mobile communication terminal, and these
  • data is then sent to a unit, e.g. B. forwarded to a sensor or to the elevator control unit of the elevator system.
  • a significant advantage of the inventive method is that a mobile communication terminal can be used as a way to transfer data from an elevator system to a monitoring unit of a service center.
  • This has the particular advantage that the radio range of the second wireless communication network can be limited to the area of the elevator car, which reduces the energy consumption of the second wireless communication network, its electromagnetic interference and its manufacturing costs to a minimum.
  • Another advantage of the inventive method is the fact that data can be transmitted to a monitoring unit of a service center, although no direct communication link between a communication unit of the elevator installation and the monitoring unit exists. Often, due to building-related shielding, no wireless connection between a communication unit located in an elevator shaft and a monitoring unit remote from the elevator shaft can be realized because no connection can be established from the communication unit to a base station of a public wireless communication network. By the method according to the invention, this is possible, at least with a time delay.
