Abstract

Disclosed are a method for sensing an emergency in response to a physical shock and a mental shock and an apparatus using the method. According to the method, whether a person is in an emergency state is determined by analyzing the physical shock and mental shock applied to the person and the emergency is automatically sensed without any effort on the part of the victim, whereby the rate at which an emergency is sensed in real time may be increased and the incidence of false determination on the emergencies may be reduced.

Claims

1. An apparatus for sensing an emergency in response to a physical shock and a mental shock, comprising:

an impact acceleration sensor module for measuring a level of physical shock applied to a body;

a physical shock data conversion module for receiving output from the impact acceleration sensor module and converting a level of shock per unit time into the level of physical shock;

a sound sensor module for receiving sound or voice for measuring a level of mental shock;

a mental shock data conversion module for converting a decibel level of the sound or voice, input from the sound sensor module, into the level of mental shock, or converting the sound or voice into the level of mental shock by checking whether a waveform of the input sound or voice is identical to that of a keyword registered in advance;

a combined shock data conversion module for acquiring a combined shock level by analyzing dynamics such as an order in which the physical shock and the mental shock occur, a change in intensity of the physical shock and the mental shock, and the like;

an emergency determination module for categorizing one or more of the level of physical shock, the level of mental shock, and the combined shock level into a preceding emergency factor, which corresponds to a level of shock that occurred first, and a following emergency factor, which corresponds to a level of shock that occurred after a preset time period, and determining whether an emergency exists by mapping the preceding emergency factor to the following emergency factor using a preset mapping table;

an alarm module for outputting an emergency signal when the emergency determination module determines that an emergency exists; and

a data storage module for storing the level of physical shock, a time at which the physical shock occurred, the level of mental shock, a time at which the mental shock occurred, the combined shock level, sound data, and GPS data.

2. The apparatus of claim 1, wherein the physical shock data conversion module converts a measured impact acceleration into an actual level of physical shock, which is one of a shock level corresponding to a large shock beyond a fall, a shock level corresponding to pushing strongly and instantly, a shock level corresponding to fast running, a shock level corresponding to walking or being dragged, and a shock level in which a degree of movement is equal to or less than a predetermined value.

3. The apparatus of claim 1, wherein the mental shock data conversion module is configured to:

convert the decibel level, measured by the sound sensor module, into the level of mental shock, which is one of a shock level corresponding to a cry, a shock level corresponding to a cry of a baby, or a shock level at which sending an SOS is necessary; and

convert the input voice, received from the sound sensor module, into the level of mental shock by checking whether the waveform of the input voice is identical to that of the keyword registered in advance.

4. The apparatus of claim 1, wherein the combined shock data conversion module is configured to:

calculate the combined shock level in order to determine whether an emergency exists, which varies depending on a physical condition of a person who receives the physical shock even if an identical shock is applied; and

calculate the combined shock level by analyzing dynamics, such as the order in which the physical shock and the mental shock occur and the change in the intensity of the physical shock and the mental shock, in conjunction with behavioral science.

5. A method for sensing an emergency in response to a physical shock and a mental shock, which uses an impact acceleration sensor module for measuring a level of physical shock applied to a body, a physical shock data conversion module for receiving output from the impact acceleration sensor module and converting a degree of shock per unit time to a level of physical shock, a sound sensor module for receiving sound or voice for measuring a level of mental shock, a mental shock data conversion module for converting a decibel level of the sound or voice, input from the sound sensor module, into the level of mental shock, or converting the input sound or voice into the level of mental shock by checking whether a waveform of the input sound or voice is identical to that of a keyword registered in advance, a combined shock data conversion module for acquiring a combined shock level by analyzing dynamics such as an order in which the physical shock and the mental shock occur, a change in intensity of the physical shock and the mental shock, and the like, an emergency determination module for determining whether an emergency exists depending on whether the level of physical shock, the level of mental shock, or the combined shock level is equal to or greater than a reference value, an alarm module for outputting an emergency signal when the emergency determination module determines that an emergency exists, and a data storage module for storing the level of physical shock, a time at which the physical shock occurred, the level of mental shock, a time at which the mental shock occurred, the combined shock level, sound data, and GPS data,

the method comprising:

continuously collecting the physical shock level, the mental shock level, and the combined shock level from the physical shock data conversion module, the mental shock data conversion module, and the combined shock data conversion module at regular intervals;

categorizing one or more of the physical shock level, the mental shock level, and the combined shock level into a preceding emergency factor, which corresponds to a level of shock that occurred first, and a following emergency factor, which corresponds to a level of shock that occurred after a preset time period, and determining whether or not an emergency exists by mapping the preceding emergency factor to the following emergency factor using a preset mapping table;

when it is determined that an emergency exists at the determining, activating a camera and a microphone, acquiring images using the camera, and acquiring sound using the microphone in order to check a situation at a site;

generating image data from the images captured by the camera and generating sound data from the sound recorded by the microphone; and

transmitting the generated image data and the generated sound data to an external terminal.
