Abstract
An elevator monitoring system and method includes cabin-based radars monitor doors and passengers within a cabin; waiting zone radars monitor passengers in a waiting zone; a central processor analyzes data from the various monitors and executes an elevator control function to control the elevator system. The door state is determined by detecting reflections from internal angles within the cabin and a door management system manages door operation safely by monitoring a proximal zone around the automatic door, detecting moving objects and obstructions.
Claims20
A method for providing an elevator monitoring system for monitoring passengers using an elevator system, the method comprising:
- providing at least one cabin-based radar monitor configured and operable to monitor passengers within at least one elevator cabin;
- providing at least one waiting zone radar monitor configured and operable to monitor passengers in a waiting zone, the waiting zone comprising at least one target region around an automatic door and at least one danger region where items may obstruct the door;
- providing a central processor configured and operable to receive data from the at least one cabin-based radar monitor and the at least one waiting zone radar monitor, to analyze the data received from the at least one cabin-based radar monitor and the at least one waiting zone radar monitor and to execute an elevator control function to control the elevator system;
- capturing a reference background of the at least one danger region;
- providing a door management processor configured and operable to select a door state;
- the door management processor receiving raw data from the at least one waiting zone radar monitor;
- the door management processor removing a background from the raw data from a proximal zone thereby calculating a proximal zone differential;
- comparing the proximal zone differential to a first threshold value;
- in response to the proximal differential exceeding the first threshold value then identifying a moving object;
- monitoring the moving object over multiple frames;
- calculating a direction of motion associated with the moving object;
- detecting current door state;
- in response to the direction of motion moving towards then, and the door state is CLOSED, then the door management processor receiving raw data from the at least one waiting zone radar monitor;
- subtracting the reference background from the raw data from the at least one danger region;
- calculating a danger zone differential;
- comparing the danger zone differential to a second threshold value;
- if the danger zone differential exceeds the second threshold value then identifying an obstruction;
- if the danger zone differential does not exceed the second threshold value then opening the door;
- and
- setting the door state to OPEN.

- at least one waiting zone radar monitor configured and operable to monitor passengers in a waiting zone, the waiting zone comprising at least one target region around an automatic door and at least one danger region where items may obstruct the door;
- a central processor configured and operable to receive data from the at least one cabin-based radar monitor and the at least one waiting zone radar monitor, to analyze the data received from the at least one cabin-based radar monitor and the at least one waiting zone radar monitor and to execute an elevator control function to control the elevator system;
- and
- a door management processor configured and operable to receive data from the at least one waiting zone radar monitor and further operable to calculate a proximal zone differential and a danger zone differential.
A method for monitoring a door, the method comprising:
- providing a proximal zone radar monitor comprising a transmitter, a receiver and a processor;
- the transmitter of the proximal zone radar monitor producing a beam of electromagnetic radiation directed towards a target region around the door;
- the receiver of the proximal zone radar monitor receiving electromagnetic radiation reflected back from objects within the target region around the door;
- the processor receiving raw data from the receiver;
- the processor removing a background from the raw data thereby calculating a differential;
- comparing the differential to a threshold value;
- in response to the differential exceeding the threshold value then identifying a moving object;
- monitoring the moving object over multiple frames;
- calculating a direction of motion associated with the moving object;
- in response to the direction of motion moving towards and door state is CLOSED, then opening the door;
- setting the door state to OPEN.
