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 policies in a mobile terminal corresponding to at least one kind of gas in different concentration ranges respectively;

detecting a gas by the mobile terminal;

adopting a warning policy in accordance with the detected concentration of the gas by the mobile terminal; and

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

2. The method according to claim 1, wherein the gas being detected comprises a combination of more than one kind of gas.

3. The method according to claim 2, wherein the step of setting warning policies comprises:

setting warning levels corresponding to the more than one kind of gas in different concentration ranges respectively; and

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

4. The method according to claim 3, wherein the mobile terminal performs the warning based on the warning policy corresponding to the highest warning level in the warning levels of the more than one kind of gas being detected.

5. The method according to claim 1, wherein each of the warning policies comprises dialing an emergency call, ringing, vibrating, or a combination thereof.

6. The method according to claim 1, wherein the step of performing a warning by the mobile terminal further comprises displaying the type and concentration of the detected gas by the mobile terminal.

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

a central control unit;

a gas detection unit for detecting the type and concentration of at least one kind of gas;

a warning unit for obtaining a warning policy based on a detection result of the type and concentration of a gas and a preset corresponding relation between the gas concentration and the warning policy; and

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

8. The mobile terminal according to claim 7, wherein the gas detection unit is set within the mobile terminal.

9. The mobile terminal according to claim 7, wherein the gas detection unit is set outside the mobile terminal and connected to the mobile terminal via a peripheral interface.

10. The mobile terminal according to claim 7, 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 of the gas type and concentration from the gas detection unit to the warning unit and controls the user interface unit to perform a corresponding warning operation in accordance with the warning policy from the warning unit.

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

12. The mobile terminal according to claim 7, wherein a warning operation according to the warning policies comprises dialing an emergency call, ringing, vibrating, or a combination thereof.

13. The mobile terminal according to claim 7, wherein the gas comprises a combination of more than one kind of gas.

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

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

a gas detection unit connected to the control unit, for detecting the type and concentration of at least one kind of gas;

a warning unit connected to the control unit, for determining a warning policy based on a detection result of the type and concentration of a gas and a preset corresponding relation between the gas detection result and the warning policy; and

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

15. The mobile terminal according to claim 14, wherein the gas detection unit is set within the mobile terminal.

16. The mobile terminal according to claim 14, wherein the gas detection is set outside the mobile terminal and connected to the mobile terminal via a peripheral interface.

17. The mobile terminal according to claim 14, wherein the central control unit receives the detection result of the gas type and concentration from the gas detection unit and sends the detection result to the warning unit, the warning unit determines the warning policy according to the detection result and the preset corresponding relation between the gas detection result and the warning policy, and transmits the warning policy to the central control unit.

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

19. The mobile terminal according to claim 14, wherein a warning operation according to the warning policy comprises dialing an emergency call, ringing, vibrating, or a combination thereof.

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

detecting air by a mobile terminal; and

performing a warning by the mobile terminal in accordance with the detection result of a kind of gas in the air.

21. The method according to claim 20, wherein the step of detecting air comprises detecting the concentration of the kind of gas.
