Abstract

Provided are an acoustic sensor and a home appliance system comprising the same. The acoustic sensor comprises a communication unit, a microphone to collect an acoustic signal, a memory to store a failure acoustic signal of a home appliance, and a processor, wherein in response to the acoustic signal, collected by the microphone, corresponding to the failure acoustic signal of the home appliance, the processor transmits the collected acoustic signal, or data corresponding to the collected acoustic signal, to an external server or a terminal. Accordingly, failure of the home appliance may be easily diagnosed.

First claim

What is claimed is:

1. An acoustic sensor, comprising:
a communication unit;
a microphone to collect an acoustic signal;
a sensor unit to output infrared light and receive light corresponding to the output infrared light;
a memory to store a failure acoustic signal of a home appliance; and
a processor, wherein in response to the acoustic signal, collected by the microphone, corresponding to the failure acoustic signal of the home appliance, the processor transmits the collected acoustic signal, or data corresponding to the collected acoustic signal, to an external server or a terminal, wherein in response to the acoustic signal, collected by the microphone, being at a reference level or higher, the processor activates the sensor unit which is in an inactive state.

2. The acoustic sensor of claim 1 , wherein in response to the acoustic signal, collected by the microphone, corresponding to the failure acoustic signal of the home appliance, the processor determines that the home appliance has broken down, based on the failure acoustic signal of the home appliance.

3. The acoustic sensor of claim 1 , wherein in response to the acoustic signal, collected by the microphone, corresponding to an operation acoustic signal of the home appliance, the processor transmits the collected acoustic signal, or data corresponding to the collected acoustic signal, to the external server or the terminal.

4. The acoustic sensor of claim 3 , wherein in response to the acoustic signal, collected by the microphone, corresponding to the operation acoustic signal of the home appliance, the processor determines an operation state of the home appliance based on the operation acoustic signal of the home appliance.

5. The acoustic sensor of claim 1 , wherein when a door of the home appliance is opened or closed while the acoustic sensor is attached to the home appliance, the processor transmits a door opening or closing acoustic signal, collected by the microphone, or data corresponding to the door opening or closing acoustic signal, to the external server or the terminal.

6. The acoustic sensor of claim 5 , wherein in response to the acoustic signal, collected by the microphone, corresponding to the door opening or closing acoustic signal of the home appliance, the processor determines opening or closing of the door of the home appliance based on the door opening or closing acoustic signal of the home appliance.

7. The acoustic sensor of claim 1 , wherein in response to an acoustic signal, indicating an operation mode input for a home appliance, being input through the microphone, the processor enters the operation mode for the home appliance.

8. The acoustic sensor of claim 1 , wherein in response to a moving object being detected, the processor transmits a warning signal to the external server or the terminal based on the output infrared light, which is output from the sensor unit, and the received infrared light which is received by the sensor unit.

9. The acoustic sensor of claim 1 , further comprising a sound output unit, wherein the processor outputs a sound, received by the communication unit, through the sound output unit.

10. A home appliance system, comprising:
a home appliance;
an acoustic sensor attached to the home appliance or disposed near the home appliance; and
a server, wherein in response to a failure acoustic signal of the home appliance being collected by the acoustic sensor, the server receives the failure acoustic signal of the home appliance, or data corresponding to the failure acoustic signal of the home appliance, from the acoustic sensor, wherein the acoustic sensor outputs infrared light and receives light corresponding to the output infrared light, wherein in response to an acoustic signal, collected by a microphone, being at a reference level or higher, the acoustic sensor activates the sensor which is in an inactive state.

11. The home appliance system of claim 10 , wherein in response to the acoustic signal, collected by the acoustic sensor, corresponding to the failure acoustic signal of the home appliance, the server determines that the home appliance has broken down, based on the failure acoustic signal of the home appliance.

12. The home appliance system of claim 10 , wherein in response to the acoustic signal, collected by the acoustic sensor, corresponding to an operation acoustic signal of the home appliance, the server receives the collected acoustic signal, or data corresponding to the collected acoustic signal, from the acoustic sensor.

13. The home appliance system of claim 12 , wherein in response to the acoustic signal, collected by the acoustic sensor, corresponding to the operation acoustic signal of the home appliance, the server determines an operation state of the home appliance based on the operation acoustic signal of the home appliance.

14. The home appliance system of claim 10 , wherein when a door of the home appliance is opened or closed while the acoustic sensor is attached to the home appliance, the server receives a door opening or closing acoustic signal, collected by the acoustic sensor, or data corresponding to the door opening or closing acoustic signal, from the acoustic sensor.

15. The home appliance system of claim 14 , wherein in response to the acoustic signal, collected by the acoustic sensor, corresponding to the door opening or closing acoustic signal of the home appliance, the server determines opening or closing of the door of the home appliance based on the door opening or closing acoustic signal of the home appliance.

16. The home appliance system of claim 10 , wherein in response to an acoustic signal, indicating an operation mode input for a home appliance, being input to the microphone of the acoustic sensor, the acoustic sensor enters the operation mode for the specific home appliance.

17. The home appliance system of claim 10 , wherein in response to a moving object being detected, the server receives a warning signal from the acoustic sensor based on the output infrared light, which is output from the acoustic sensor, and the received infrared light, which is received by the acoustic sensor.

18. The home appliance system of claim 10 , wherein the server transmits a sound to the acoustic sensor, wherein the acoustic sensor outputs the sound, received by the server, through a sound output unit of the acoustic sensor.
