The present invention relates to a system for preventing a negligent accident in a small space using a user terminal-based portable sensor which includes: at least one sensor unit which is installed in a predetermined location of the small space and has an event detection sensor which has at least one among proximity sensor for detecting an approach of object within a predetermined range, fire sensor for detecting smoke or temperature if the temperature is at least a predetermined temperature, and a sound sensor for detecting sound if the intensity of the sound is at least a predetermined dB; a signal generation unit for generating an event generation signal corresponding to an event if the event is detected at the event detection unit; and a first signal transmission unit for transmitting an event generation signal generated in the signal generation unit. The present invention also includes a user terminal which is wirelessly connected to the sensor unit, displaying an event generation signal when receiving the event generation signal from the first signal transmission unit and generating a notification sound and a vibration. According to the present invention, the system for preventing a negligent accident in a small space using a user terminal-based portable sensor and the method thereof, which are capable of installing sensors for detecting an event such as fire, intrusion indoor or at the outside and the like by increasing the portability thereof, are provided. |
