On the other hand, as a result of confirming that the harmful gas data corresponding to the section away from the current vehicle by using the controller 7 is stored in the memory 5 (S3), the harmful gas corresponding to the section away from the vehicle at a certain distance. If the data is not stored in the memory 5, the gas detection unit 1 is used to check whether or not harmful gas exists at the current vehicle position (S5, S6).

In this case, as a result of confirming whether a harmful gas of a predetermined value or more is detected at the current vehicle position through the gas detector 1 (S6), if a harmful gas of a certain value or more is detected, the control unit 9 operates the alarm unit 7. By sending an alarm message to the driver (S7) and storing the harmful gas data corresponding to the current vehicle position and the current vehicle position in the memory 5 (S8) and checks whether the vehicle operation is finished. S9)

On the other hand, as a result of confirming that no harmful gas more than a predetermined value is detected at the current vehicle position (S6), if no harmful gas more than a predetermined value is detected, the controller 7 is configured to store the noxious gas data corresponding to the current vehicle position in the memory ( 5) Check whether it is stored on (S10).

Next, if the harmful gas data corresponding to the current vehicle position is stored in the memory 5, the controller 7 deletes the harmful gas data corresponding to the current vehicle position and the current vehicle position from the memory 5. (S11) Check whether the vehicle operation is finished. (S9)

Next, as a result of checking whether the vehicle operation is finished (S9), if the vehicle is continuously driven, the control unit 9 detects the position of the current vehicle using the GPS receiver 3 (S1). By moving to perform the above process repeatedly. (S12)

On the other hand, as a result of checking whether the vehicle operation is terminated (S9), if the vehicle operation is terminated, the above process is terminated.

The automatic harmful gas detection system according to the present invention having such a structure searches for the current vehicle position using the GPS receiver 3, and searches the air pollution state of a section away from the current vehicle position in the memory 5. Then, before the vehicle enters the pollution section, the driver may inform the driver of the air pollution information in the corresponding section in advance.

In addition, the automatic harmful gas detection system according to the present invention, if the current vehicle position is not stored in the memory 5 as the air pollution section, if the harmful gas is detected at the current vehicle location, the air pollution information in the specific section The driver may be informed of the pollution information to the driver after a new update in the memory 5, and if the harmful gas is not detected as a result of driving the air pollution section in the current memory 5 but the air pollution section is detected, the current memory ( Location information and air pollution information stored in 5) can be deleted from the memory (5).

Therefore, the automatic hazardous gas detection system according to the present invention notifies the driver of the air pollution state before the vehicle enters the air pollution section in advance, and can automatically update the air pollution status in the specific section without any work. There is an advantage, and when the driver re-driving in the section, there is an advantage that can provide updated information to the driver at all times.
