  • Hall effect sensor 10 is electrically conductively connected to monitoring circuit 200 via an electrical connection, here a cable, and is able to transmit recorded data, in particular measurement data, to monitoring circuit 200 and to receive data, in particular control data, from it.
  • the Hall effect sensor 10 is physically located in close proximity to a safety circuit of the car 290 and configured to measure the electromagnetic field generated by a current flowing through the safety circuit of the car 290 .
  • the monitoring unit 200 also includes an energy source 150, which is provided as an emergency power battery in order to be able to supply the monitoring unit 200 and in particular its sensor units 180 with energy in the event of a power failure.
  • the monitoring unit 200 includes, purely by way of example, an actuating means 14 which is also designed as a service button or as a push button. When this service button or pushbutton is actuated, the monitoring unit 200 establishes the presence of a person—for example a fitter—in the vicinity of the monitoring unit 200 and thus on the roof of the elevator car 290 .
  • Examples of such irregular or erroneous operating behavior are, for example, an abrupt interruption of operation or a journey if the car 290 gets stuck in the elevator shaft 285, or a journey with the doors open in the elevator shaft 285, stopping at stations of the elevator too early or too late 300, so that steps have to be overcome when exiting or boarding, or the doors of the elevator car 290 being opened and closed multiple times.
  • the arrangement of the various sensor units 180 can be different than in FIG figure 1 shown and described for the first embodiment.
  • the temperature sensor 3, the humidity sensor 4, the atmospheric pressure sensor 5, the acceleration sensor 8, the laser sensor 11 and the inclination sensor 13 can also be arranged partially or completely outside the housing 190 of the monitoring unit 200.
  • the light sensor 6, the movement sensor 7, the audio sensor 9 provided according to the invention, the Hall effect sensor 10 and/or the vibration sensor 12 can be arranged within the housing 190 of the monitoring unit 200.
  • FIG 2 a second exemplary embodiment of a monitoring unit 200 according to the invention is shown.
  • the second embodiment is essentially identical to the first in figure 1 shown embodiment, so that components with the same designation have the properties and functions described above. What was previously described for these components therefore also applies to the in figure 2 components with the same name.
  • the monitoring unit 200 includes, purely by way of example, two modules 201, 202 which are able to communicate with one another via a wireless Bluetooth connection 20 and exchange data with one another.
  • the monitoring unit 200 in this second exemplary embodiment comprises a car roof module 201, which is attached to the outside of the roof of the car 290 of an elevator 300, i.e. is not located inside the car 290, and a car module 202, which is arranged inside the car 290 .
  • the car module 202 is mounted on the inside of the roof of the car 290 .
  • the car roof module 201 comprises a communication unit 170 designed as a mobile radio module, by means of which data, in particular measurement data and/or control data, can be sent and received to and via a mobile radio communication network.
  • a data cellular connection 30 to a server is in figure 2 represented by a dashed double arrow.
  • the car roof module 201 includes a gateway 260, via which data recorded or generated by the sensor units, in particular measurement data, can be and are transmitted to the mobile radio module.
  • the car roof module 201 also includes a temperature sensor 3 and a humidity sensor 4, a 3-axis acceleration sensor 8 and a motion sensor 7, which is designed as a presence sensor for detecting the presence of people on or in the car 290. Furthermore, the car roof module 201 in this second exemplary embodiment comprises a Hall effect sensor 10, by means of which an electromagnetic field can be measured, as well as an audio sensor 9 designed as an acoustic sensor and provided according to the invention, and a laser measuring system 11 actuating means 14 designed as a service button is provided in the car roof module 201 .
  • a signal generated upon actuation of the actuating means 14 is also transmitted to the gateway 260 and forwarded by it to the mobile radio module. From this, the data and signals are forwarded to a server in this second exemplary embodiment, where they are fed to an evaluation. In other words, in this second exemplary embodiment, the recorded measurement data is not evaluated within the monitoring unit 200. This evaluation is carried out on an external server.
  • monitoring units 200 according to the invention can also be implemented in which the evaluation takes place within at least one evaluation unit which is comprised by the monitoring unit 200 .
  • the car roof module 201 also includes a further communication unit 170, which is designed as a Bluetooth Low Energy module, ie as a Bluetooth LE module.
  • the car module 202 also includes such a communication unit 170, which is designed as a Bluetooth LE module. Using these Bluetooth LE modules, the car roof module 201 to exchange data, signals and information with the car module 202 via the Bluetooth connection 20 already mentioned above.
  • the car module 202 includes, purely by way of example, a light sensor 6, a motion sensor 7, a temperature sensor 3 and a humidity sensor 4. Measurement data and signals recorded by these sensor units of the car module 202 are transmitted via the communication module 170 of the car module 202, i.e. via the Bluetooth LE module, transmitted to the Bluetooth LE module of the car roof module 201, which forwards the measurement data and signals to the gateway 260.
  • This gateway 260 transmits the measurement data and signals from the sensor units of the car module 202 to the mobile radio module, which transmits the data via the data mobile radio link 30 to a server.
