Abstract
A detection system is provided. The detection system includes a sensing device and a controller. The sensing device is within an elevator and in communication with the controller. The sensing device continuously monitors sound waves within the elevator and communicates the sound waves as electrical signals to the controller. The controller operates the elevator and analyses the sound waves received as the electrical signals from the sensing device to detect an emergency condition within the elevator.
Claims18
A detection system comprising:
- a controller operable to receive sound waves from at least one sensing device configured within an elevator, the at least one sensing device operable to continuously monitor sound waves within the elevator and communicate the sound waves as electrical signals to the controller;
- and
- the controller operating the elevator and analyzing the sound waves received as the electrical signals from the at least one sensing device to detect an emergency condition within the elevator;
- wherein the emergency condition comprises a person speaking under agitated circumstances;
- and
- the controller operable to perform a confirmation analysis of the emergency condition, wherein the confirmation analysis comprises cancelling the emergency condition if, subsequent to the detection of the emergency condition, analyzing the sound waves results in a determination that the person is no longer speaking under agitated circumstances.
