Definitions

  • the present disclosure relates to a detection method and detection system for detecting people trapped in an elevator car.
  • an aspect according to the present disclosure provides a detection method for detecting people trapped in an elevator car, the detection method includes: setting an elevator controller of an elevator to acquire state parameters of an elevator car in real time; setting a digital transmission unit of the elevator to continuously acquire the state parameters from the elevator controller and continuously store the state parameters.
  • the digital transmission unit detects whether the elevator car is in a people-trapped state according to a logical combination of the state parameters as acquired one second before power-off.
  • the state parameters also include a number of unfinished internal call from inside of the elevator car.
  • the digital transmission unit judges that the real-time load of the elevator car is greater than the empty car load of the elevator car, judges that the real-time state of the door of the elevator car is in a closed state and judges that the unfinished internal call exists, the digital transmission unit sends out a people-trapped signal.
  • the digital transmission unit when the elevator is in a power-off state, sends the second signal, the real-time load of the elevator car, the real-time state of the door of the elevator car, the number of unfinished internal call and the people-trapped signal to a remote server.
  • the state parameters include a real-time load of the elevator car, a real-time state of a door of the elevator car and a number of unfinished internal call from inside of the elevator car; when the elevator is in a non-power-off state, if the digital transmission unit judges that the real-time load of the elevator car is greater than the empty car load of the elevator car, judges that the real-time state of the door of the elevator car is in a closed state, and judges that the unfinished internal call exists, the digital transmission unit sends out a people-trapped signal.
  • the state parameters also includes a number of unfinished internal call from inside of the elevator car.
  • the digital transmission unit judges that the real-time load of the elevator car is greater than the empty car load of the elevator car, judges that the real-time state of the door of the elevator car is in a closed state and judges that the unfinished internal call exists, the digital transmission unit sends out a people-trapped signal.
  • the state parameters include a real-time load of the elevator car, a real-time state of a door of the elevator car and a number of unfinished internal call from inside of the elevator car; when the elevator is in a non-power-off state, if the digital transmission unit judges that the real-time load of the elevator car is greater than an empty car load of the elevator car, judges that the real-time state of the door of the elevator car is in a closed state, and judges that the unfinished internal call exists, the digital transmission unit sends out a people-trapped signal.
  • the technical solution according to the present disclosure has the following technical advantages: judging whether there are passengers in the elevator car in an intelligent way by using the internal message of the elevator controller, even in the case of power failure, all controller data will be lost, and no additional sensors need to be installed, which can meet the intention of reducing costs.
  • the remote monitoring function is added to the system. Once the trapped person is confirmed, the alarm will be sent to the remote technicians.
  • a detection method for detecting people trapped in an elevator car includes: setting an elevator controller 1 of an elevator to acquire state parameters of an elevator car 3 in real time; setting a digital transmission unit 2 of the elevator to continuously acquire the state parameters from the elevator controller 1 and continuously store the state parameters.
  • the power management device 4 is used for detecting whether the elevator is in a power-off state or not and supplying power to the digital transmission unit 2.
