Abstract

A method and a terminal for acquiring road condition information are provided, wherein, the method includes: forming an Ad Hoc network with other terminals; acquiring own position information through positioning; exchanging position information with other terminals in a network through the Ad Hoc network; and acquiring the road condition information according to the exchanged position information. The present method realizes a technical effect of acquiring the road condition information without an operator.

Claims

1. A method for acquiring road condition information, comprising:

forming an Ad Hoc network with other terminals;

acquiring own position information through positioning;

exchanging position information with other terminals in a network through the Ad Hoc network;

acquiring the road condition information according to the exchanged position information.

2. The method according to claim 1, wherein, the step of exchanging position information with other terminals in a network through the Ad Hoc network comprises:

exchanging the position information with the other terminals in the network through the Ad Hoc network every other preset time;

or,

exchanging the position information with the other terminals in the network through the Ad Hoc network when the own position information changes.

3. The method according to claim 1, wherein, the step of acquiring the road condition information according to the exchanged position information comprises:

setting a relative distance D1, and raising an alarm when detecting that a relative distance between a position of the other terminal and an own position is less than D1 according to the exchanged position information.

4. The method according to claim 3, further comprising:

exchanging a terminal ID with the other terminals in the network through the Ad Hoc network.

5. The method according to claim 4, wherein, the step of acquiring the road condition information according to the exchanged position information comprises:

setting a relative distance D2 to a designated terminal ID, and raising an alarm when detecting that a relative distance between a position of the designated terminal ID and the own position is greater than D2 according to the exchanged position information.

11. The method according to claim 2, wherein, the step of acquiring the road condition information according to the exchanged position information comprises:

setting a relative distance D1, and raising an alarm when detecting that a relative distance between a position of the other terminal and an own position is less than D1 according to the exchanged position information.

12. The method according to claim 11, further comprising:

exchanging a terminal ID with the other terminals in the network through the Ad Hoc network.

13. The method according to claim 12, wherein, the step of acquiring the road condition information according to the exchanged position information comprises:

setting a relative distance D2 to a designated terminal ID, and raising an alarm when detecting that a relative distance between a position of the designated terminal ID and the own position is greater than D2 according to the exchanged position information.

6. A terminal for acquiring road condition information, comprising an Ad Hoc network connection module, a positioning module, an information interaction module and a road condition information acquiring module, wherein:

the Ad Hoc network connection module is configured to form an Ad Hoc network with other terminals;

the positioning module is configured to acquire own position information through positioning;

the information interaction module is configured to exchange position information with other terminals in a network through the Ad Hoc network; and

the road condition information acquiring module is configured to acquire the road condition information according to the exchanged position information.

7. The terminal according to claim 6, wherein:

the information interaction module is configured to exchange the position information with the other terminals in the network through the Ad Hoc network every other preset time;

or, exchange the position information with the other terminals in the network through the Ad Hoc network when the own position information changes.

8. The terminal according to claim 6, wherein:

the road condition information acquiring module is configured to set a relative distance D1, and raise an alarm when detecting that a relative distance between a position of the other terminal and an own position is less than D1 according to the exchanged position information.

9. The terminal according to claim 8, wherein:

the information interaction module is further configured to exchange a terminal ID with the other terminals in the network through the Ad Hoc network.

10. The terminal according to claim 9, wherein:

the road condition information acquiring module is further configured to set a relative distance D2 to a designated terminal ID, and raise an alarm when detecting that a relative distance between a position of the designated terminal ID and the own position is greater than D2 according to the exchanged position information.

14. The terminal according to claim 7, wherein:

the road condition information acquiring module is configured to set a relative distance D1, and raise an alarm when detecting that a relative distance between a position of the other terminal and an own position is less than D1 according to the exchanged position information.

15. The terminal according to claim 14, wherein:

the information interaction module is further configured to exchange a terminal ID with the other terminals in the network through the Ad Hoc network.

16. The terminal according to claim 15, wherein:

the road condition information acquiring module is further configured to set a relative distance D2 to a designated terminal ID, and raise an alarm when detecting that a relative distance between a position of the designated terminal ID and the own position is greater than D2 according to the exchanged position information.
