Abstract

A sensing device for sensing an emergence situation having an acceleration sensor and a method thereof are provided. The sensing device includes acceleration sensing means, blood pressure/pulse sensing means, comparing means, communication means, and a controller. The accelerating sensing means senses acceleration generated due to movement of the body and the blood pressure/pulse sensing means senses a blood pressure and a pulse of a user. The comparing means compares acceleration, a blood pressure, and a pulse with a reference acceleration, a reference blood pressure, and a reference pulse, generates an acceleration abnormal signal, a blood pressure abnormal signal, and a pulse abnormal signal, and outputs an emergency situation signal. The communication means transmits the emergency situation signal to an external apparatus through a communication network and the controller controls the communication means to transmit the emergency situation signal to the external apparatus if an emergency situation signal is generated from the comparing means.

Claims

acceleration sensing means worn on a body of a user, for sensing acceleration generated due to movement of the body;

blood pressure/pulse sensing means for sensing a blood pressure and a pulse of a user;

comparing means for comparing acceleration, a blood pressure, and a pulse inputted from the acceleration sensing means and the blood pressure/pulse sensing means with a reference acceleration, a reference blood pressure, and a reference pulse, generating an acceleration abnormal signal, a blood pressure abnormal signal, and a pulse abnormal signal if compared differences are greater than preset values, and outputting an emergency situation signal if both the acceleration abnormal signal and at least one of the blood pressure abnormal signal and the pulse abnormal signal exist;

communication means for transmitting the emergency situation signal to an external apparatus through a communication network; and

a controller for controlling the communication means to transmit the emergency situation signal to the external apparatus if the emergency situation signal is generated from the comparing means.

5. A sensing device for sensing an emergence situation having an acceleration sensor comprising:

acceleration sensing means worn on a body of a user, for sensing acceleration generated due to movement of the body;

comparing means for judging whether the acceleration generated from the acceleration sensing means exceeds a preset value;

communication means for checking whether an emergency situation is true or not if the acceleration value is judged to exceed the preset value, and informing the emergency situation to an outside if the emergency situation is actually generated; and
