Definitions

  • the invention relates to a method and a device for exchanging data between at least one sensor unit arranged in an elevator shaft of an elevator installation and a monitoring unit of a service center which is remote from the elevator installation, wherein an elevator car traveling vertically in the elevator shaft is used in the elevator installation, at which a first Communication unit is arranged.

  • the location of the elevator operating unit is determined based on the signal strength and the elevator car is sent to the corresponding floor of the elevator operating unit.
  • Document EP 1415947 A1 discloses a device for the remote maintenance and monitoring of an elevator installation with at least one input for detecting first signals from an elevator control and / or from a sensor with at least one output of second signals to a telecommunication network and with 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.
  • a point-to-point connection or a multi-hop method is frequently used for wireless or mobile communication. Under a point-to-point connection is understood in telecommunications a direct connection without intermediate stations.
  • hop In contrast, in a multihop method, data is transmitted via intermediate stations. The transition from one station to the next is called hop.
  • hop In general, a distinction is made between single (or simple) hop connections in which there is exactly one station or hop between sender and receiver, and multi-hop connections in which the data (packets) are passed on via several intermediate stations.
  • multihop communication networks one also speaks of the n-hop neighborhood of a station, where n is replaced by a natural number. These are all network nodes that can be reached from the observed intermediate station via at most n hops.
  • the hop count is the number of steps a packet must travel on the way from the sender to the receiver, with the number of intermediate stations along that path being one less.
  • a disadvantage of such methods is that such communication networks require a high radio range and antenna power so that secure communication can be ensured. Also, complex network protocols are often used which generate a high traffic load due to security requirements in the transmission of data. Thus, while ensuring a secure and reliable connection establishment, reliable delivery of data packets, and ensuring error-free transmission between the units involved in the communication, the (communication) units have high energy consumption through such network protocols.
  • An object of the invention is to propose a simple and energy-efficient communication method for an elevator installation.
