20200134995
This application claims priority under 35 U.S.C. § 119 to Korean Application No. 10-2018-0132148 filed on Oct. 31, 2018, whose entire disclosure is hereby incorporated by reference.
The present invention relates to a home device, and more particularly, to a home device capable of detecting abnormal noise by using an artificial intelligence if a user goes out.
A general unmanned security alarm system is a system that detects an intruder (person or animal), not an internal person, in a house, office or factory, and notifies invasion through a warning light or a warning alarm.
Such an unmanned security alarm system has been developed from a simple system in which a door detection device installed in a doorway detects whether a door is opened or closed and notifies the intrusion into a state-of-the-art vision alarm system in which disadvantages of the simple system are remedied and performance of the system is improved.
In addition, in recent years, it is possible to detect the intrusion (movement) of an outsider through a camera of a movable robot cleaner provided at the house, take a photograph, and then transmit the photographed image to a user.
However, there is a problem that an intruder may not be detected if the intruder enters a place where the robot cleaner is not positioned, since the robot cleaner photographs only the surroundings thereof.
The embodiments will be described in detail with reference to the following drawings in which like reference numerals refer to like elements wherein:
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, in which like reference numerals refer to like or similar elements regardless of reference numerals and a duplicated description thereof will be omitted.

Referring to
In one embodiment, the processor 190 may receive a request for entry into the outgoing mode from the user's mobile terminal (e.g., cellular phone).
In another embodiment, the processor 190 may allow the operation mode of the home device 100 to enter the outgoing mode according to an input of selecting a button provided in the home device 100.
If receiving a request for entry into the outgoing mode from the mobile terminal, any one of the plurality of home devices 100-1 to 100-4 and the robot cleaner 200 provided in the house may transmit the request to the remaining home devices.
Accordingly, if any home device 100 enters the outgoing mode, the remaining home devices may also enter the outgoing mode.
Under the outgoing mode of the home device 100, the processor 190 may collect ambient noise through the microphone 123.
The microphone 123 may receive noise in real time or periodically under the outgoing mode.
The processor 190 may collect noise through the microphone 123 as it enters the outgoing mode (S303). The collected noise may be stored in the memory 130.
The microphone 123 may collect noise at intervals of 10 seconds, which is merely an example.
The processor 190 may determine whether the collected noise is abnormal noise (S305).
In one embodiment, if a pattern of sound waveform corresponding to the noise has a predetermined pattern, the processor 190 may determine that the collected noise is abnormal noise.
Specifically, if a magnitude of the sound waveform corresponding to the collected noise periodically exceeds a reference magnitude, the processor 190 may determine that a corresponding noise is an abnormal noise.
In another embodiment, if an energy level of the sound waveform corresponding to the noise periodically exceeds a reference energy level, the processor 190 may determine the noise to be abnormal noise.
The details will be described with reference to
First, referring to
The processor 190 may determine that the noise is abnormal noise if the magnitude of the sound waveform 400 exceeds the reference magnitude a reference number of times for a predetermined period of time.
If a pattern of the sound waveform 400 is detected as shown in
Next, description will be given with reference to
Referring to
If an energy level exceeds a reference level not less than the reference number of times for a certain period of time, the processor 190 may determine that the noise is abnormal noise.
In another embodiment, if the magnitude of the sound waveform 400 corresponding to the noise exceeds the reference magnitude not less than the reference number of times for the certain period of time and the energy level corresponding to the noise exceeds the reference level not less than the reference number of times for the certain period of time, the processor 190 may determine that the noise is abnormal noise.
Again, description is given with reference to
If the collected noise is determined to be abnormal noise, the processor 190 may transmit, to the robot cleaner 200, a movement command for directing the robot cleaner 200 to move to a place where the home device 100 is position (S307).
If the collected noise is determined to be abnormal noise, the processor 190 may transmit the movement command to the robot cleaner 200 through the communication unit 110.
The robot cleaner 200 may previously store position information of each of the plurality of home devices 100-1 to 100-4 provided in the house.
In another embodiment, the processor 190 may transmit the position information of the home device 100 to the robot cleaner 200 along with the movement command.
The robot cleaner 200 may control a motor provided therein so as to move to a place where the home device 100 is positioned, according to the movement command received from the home device 100 and after movement, allow a camera provided therein to capture an image of soundings (S309).
The robot cleaner 200 may determine that an intruder has broken into the house according to the movement command and may move to the position of the home device 100 that has transmitted the movement command.
Thereafter, the robot cleaner 200 may capture the surroundings of the home device 100 using the camera provided therein.
The robot cleaner 200 may transmit the captured soundings image, noise information, and an intrusion notification notifying the user that there is the intruder in the house to the user's mobile terminal (not shown) (S311).
The robot cleaner 200 may transmit at least one of an image obtained by capturing the surroundings of the home device 100, noise information inputted through a microphone provided in the robot cleaner 200, and a message informing that there is an intruder in the house, to the user's mobile terminal.
Accordingly, the user may quickly confirm that there is an intruder in his/her house even if he/she goes out.
Also, according to the embodiment of the present invention, it is possible to detect an intruder without having an expensive security system in the house.
In addition, according to the embodiment of the present invention, even if an intruder enters a place where the robot cleaner 200 is not positioned, the intruder may be detected.
Although it is described as an example that the robot cleaner 200 captures the surroundings of the home device 100 and transmits the captured image to the user's mobile terminal, the present invention is not limited thereto.
That is, in step S305, the processor 190 may capture the surroundings of the home device 100 using the camera 121 provided in the home device 100, and transmit the captured image to the user's mobile terminal, if the collected noise is determined to be abnormal noise.
In addition, if the collected noise is determined to be abnormal noise, the processor 190 may transmit an ON command for turning on a camera provided in each of the other home devices to other home devices in addition to its own camera 121.
Each of the other home devices may turn on the camera in response to the received ON command and capture the surroundings thereof. The captured image may be transmitted to the user's mobile terminal.
Accordingly, even if the intruder moves to another home device, the situation of the intruder may be monitored.
In particular,

It will be understood that when an element or layer is referred to as being “on” another element or layer, the element or layer can be directly on another element or layer or intervening elements or layers. In contrast, when an element is referred to as being “directly on” another element or layer, there are no intervening elements or layers present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
It will be understood that, although the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section could be termed a second element, component, region, layer or section without departing from the teachings of the present invention.
Spatially relative terms, such as “lower”, “upper” and the like, may be used herein for ease of description to describe the relationship of one element or feature to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “lower” relative to other elements or features would then be oriented “upper” relative the other elements or features. Thus, the exemplary term “lower” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.
