System and method for detection of a malfunction in an elevator

1. A method for detection of a malfunction in an elevator cab comprising a controller, one or more microphones, a server, the method comprising:

inputting, in the controller, at least one sound signal captured by the one or more microphones;

processing, by the controller, the at least one sound signal received from the one or more microphones;

determining, by the controller, that the at least one sound signal received by the one or more microphones has originated from the elevator cab; and

transmitting the at least one sound signal which has originated from the elevator cab to a server; and

wherein the at least one sound signal is processed at the server that detects the malfunction in the elevator cab;

wherein the one or more microphones include a first microphone positioned at a first location inside the elevator cab and a second microphone positioned at a second location inside the elevator cab, and wherein the method includes comparing, by the controller, a difference in a time of reception of a sound signal by the first microphone and the second microphone to a range of time interval values to determine if the at least one sound signal has originated from the elevator cab.

2. The method according to claim 1 , wherein the server is in communication with the elevator cab via an internet connection.

3. The method according to claim 1 , wherein the server includes a processor, a machine learning system and a smart decision service.

4. The method according to claim 1 , wherein if it is identified that a passenger is trapped in the elevator, the server connects the elevator cab to a customer care center, a human analyst, or an end user system.

5. The method according to claim 1 , wherein if it is identified that a passenger is trapped in the elevator, the method includes a step of sending a notification to a technician device to inform a technician of the trapped passenger, wherein the technician device is one of a phone, a watch, or a portable device connected to the internet.

6. A method for detection of a malfunction in an elevator cab comprising a controller, one or more microphones, a server, the method comprising:

inputting, in the controller, at least one sound signal captured by the one or more microphones;

processing, by the controller, the at least one sound signal received from the one or more microphones;

determining, by the controller, that the at least one sound signal received by the one or more microphones has originated from the elevator cab; and

transmitting the at least one sound signal which has originated from the elevator cab to a server; and

wherein the at least one sound signal is processed at the server that detects the malfunction in the elevator cab;

wherein the one or more microphones include a first microphone positioned at a first location inside the elevator cab, a second microphone positioned at a second location inside the elevator cab, and a third microphone positioned at a third location outside the elevator cab, and wherein the method includes:

comparing a difference in a time of reception of a sound signal by the first microphone and the second microphone to a range of time interval values, and

comparing an average amplitude of a sound signal received by the first microphone and the second microphone with an amplitude of a sound received by the third microphone to determine if the at least one sound has originated from the elevator cab.

7. A system for detection of a malfunction in an elevator comprising:

an elevator cab;

a server;

one or more microphones positioned in the elevator cab;

a controller configured to:

receive signals captured by the one or more microphones;

determine that the signals received by the one or more microphones have originated from the elevator cab; and

transmit the signals received by the one or more microphones which have originated from the elevator cab to a server,

wherein the server processes the transmitted signals and detects the malfunction in the elevator cab;

wherein the one or more microphones include a first microphone positioned at a first location inside the elevator cab and a second microphone positioned at a second location inside the elevator cab;

wherein the controller is configured to compare a difference in a time of reception of a sound signal by the first microphone and the second microphone to a range of time interval values to determine if the sound signal has originated from the elevator cab.
