Abstract
An elevator fire detection system (130) for early detection of smouldering and/or burning within an elevator system (100) is provided. A controller (112) is in electronic communication with at least one electronic nose detector (120) which is configured to receive a fluid mixture comprising an odorant, collect sensor data representative of the odorant, compare the sensor data to at least one olfactory reference profile, determine whether the odorant corresponds to the at least one olfactory reference profile and output an indicator signal to the controller (112) to indicate that the detected odorant corresponds to the at least one olfactory reference profile. The controller (112) after receiving the indicator signal effects a safety response action in the elevator system (100).
Claims15
An elevator fire detection system (130, 230) for early detection of smouldering and/or burning within an elevator system (100, 200), the elevator fire detection system comprising:
- at least one electronic nose detector (120, 220a, 220b, 220c, 220d);
- a controller (112, 212) in electronic communication with the at least one electronic nose detector (120, 220a, 220b, 220c, 220d) and the elevator system (100, 200);
- wherein the at least one electronic nose detector (120, 220a, 220b, 220c, 220d) is configured to:
- receive a fluid mixture comprising an odorant (302);
- collect sensor data representative of the odorant (302);
- compare the sensor data to at least one olfactory reference profile;
- determine whether the odorant (302) corresponds to the at least one olfactory reference profile;
- and
- output an indicator signal to the controller (112, 212) wherein the indicator signal indicates that the detected odorant corresponds to the at least one olfactory reference profile;
- wherein upon receipt of the indicator signal the controller (112, 212) is configured to effect a safety response action in the elevator system.
A method (400) for the early detection of burning and/or smouldering in an elevator system (100, 200), the method comprising:
- receiving a fluid mixture (410) comprising an odorant (302) at an electronic nose device (120, 220a, 220b, 220c, 220d) ;
- collecting sensor data (420) representative of the odorant (302) using the electronic nose device (120, 220a, 220b, 220c, 220d);
- comparing the sensor data (430) to at least one olfactory reference profile;
- determining (440) whether the odorant (302) corresponds to the at least one olfactory reference profile;
- outputting (460) from the electronic nose device (120, 220a, 220b, 220c, 220d) an indicator signal to a controller (112, 212);
- and
- effecting a safety response action (470) using the controller (112, 212) which is configured to be in communication with the electronic nose device (120,
- 220a, 220b, 220c, 220d) and the elevator system (100, 200).
