Abstract

A method and a mobile terminal for gas detection warning are disclosed to solve the problem that people cannot detect gas by themselves due to the lack of a portable gas detecting apparatus. The mobile terminal is portable and typically includes a central control unit, a gas detection unit, a warning unit and a user interface unit. The apparatus performs a warning operation by using a warning policy corresponding to the detected air concentration by setting warning policies corresponding to a kind of gas in different concentration ranges respectively.

Claims

1. A method for gas detection warning, comprising the steps of:

setting warning levels in a mobile terminal, the warning levels corresponding to more than one kind of gas in different concentration ranges respectively;

setting warning policies corresponding to the warning levels for the more than one kind of gas respectively;

detecting the more than one kind of gas by the mobile terminal;

determining the warning levels of each kind of gas;

adopting a warning policy corresponding to a highest warning level among the warning levels of the detected more than one kind of gas; and

performing a warning by the mobile terminal in accordance with the adopted warning policy.

2. The method according to claim 1, wherein each of the warning policies comprises at least one of:

dialing an emergency call, ringing, and/or vibrating.

3. The method according to claim 1, wherein the step of performing a warning by the mobile terminal further comprises displaying the plurality of concentrations and the corresponding type of the plurality of gasses by the mobile terminal.

16. The method according to claim 1, wherein the more than one kind of gas includes CO and H₂S.

4. A mobile terminal for gas detection warning, comprising:

a central control unit;

a gas detection unit for detecting types and concentrations of more than one kind of gas;

a warning unit for setting therein warning levels corresponding to the more than one kind of gas in respective concentration ranges, and setting warning policies corresponding to the respective warning levels in advance, determining the warning levels for each kind of gas, and obtaining a warning policy corresponding to a highest warning level based on the detection result; and

a user interface unit for displaying the detection result and performing a warning operation in accordance with the obtained warning policy.

5. The mobile terminal according to claim 4, wherein the gas detection unit is set within the mobile terminal.

6. The mobile terminal according to claim 4, wherein the gas detection unit is set outside the mobile terminal and connected to the mobile terminal via a peripheral interface.

7. The mobile terminal according to claim 4, wherein the central control unit is connected to the gas detection unit, the warning unit and the user interface unit respectively, and the central control unit sends the detection result from the gas detection unit to the warning unit and controls the user interface unit to perform the warning operation in accordance with the warning policy from the warning unit.

8. The mobile terminal according to claim 7, wherein the central control unit receives the detection result from the gas detection unit in a manner of at least one of:

an interruption and/or an inquiry.

9. The mobile terminal according to claim 4, wherein the warning operation comprises at least one of:

dialing an emergency call, ringing, and/or vibrating.

10. A mobile terminal for gas detection warning, comprising:

a central control unit for controlling and coordinating operations of the mobile terminal;

a gas detection unit connected to the control unit, for detecting types and concentrations of each of a plurality of gasses to form a detection result;

a warning unit connected to the control unit, for setting therein warning levels corresponding to the concentration of each of the plurality of gasses in a respective plurality of concentration ranges, and warning policies corresponding to the warning levels in advance, and determining a warning policy corresponding to a highest warning level among the warning levels of the detected plurality of gasses; and

a user interface unit for displaying the detection result, wherein, the central control unit gets the determined warning policy from the warning unit and controls the user interface unit to perform the warning operation according to the determined warning policy.

11. The mobile terminal according to claim 10, wherein the gas detection unit is set within the mobile terminal.

12. The mobile terminal according to claim 10, wherein the gas detection is set outside the mobile terminal and connected to the mobile terminal via a peripheral interface.

13. The mobile terminal according to claim 10, wherein the central control unit receives the detection result from the gas detection unit and sends the detection result to the warning unit, and wherein the warning unit determines the warning policy according to the detection result, and transmits the warning policy to the central control unit.

14. The mobile terminal according to claim 10, wherein the central control unit receives the detection result from the gas detection unit in a manner of interruption or inquiry.

15. The mobile terminal according to claim 10, wherein a warning operation according to the warning policy comprises at least one of:

dialing an emergency call, ringing, and/or vibrating.
