Abstract

A handheld device monitors an abnormal situation of a vehicle in real-time, and continuously records video and audio information of the vehicle. The handheld device continuously caches the recorded video and audio information, and stores the video and audio information within a first fixed time period. The handheld device stores the video and audio information within a second fixed time period when an abnormal situation of the vehicle occurs, and the video and audio information within the second fixed time period is not covered by video and audio information recorded by the video and audio recording module.

Claims

1. A handheld device for recording video and audio information of a vehicle, the handheld device comprising:

a signal generating module operable to monitor an abnormal situation of the vehicle in real-time;

a video and audio recording module operable to continuously record video and audio information of the vehicle; and

a storage system operable to continuously cache the video and audio information, and store the video and audio information that happens within a first fixed time period, and further operable to store the video and audio information that happens within a second fixed time period when the abnormal situation of the vehicle occurs, wherein the video and audio information that happens within the second fixed time period is not covered by video and audio information subsequently recorded by the video and audio recording module; and

at least one processor operable to execute the signal generating module, the video and audio recording module.

2. The handheld device of claim 1, wherein the first fixed time period is a fixed time period before a current time, the current time is the time of the abnormal situation occurs, and the second fixed time period is a fixed time period having two equal length time period, wherein one half time is the time period before the time of when the abnormal situation occurs, and the second half time is the time period after the time of when the abnormal situation occurs.

3. The handheld device of claim 1, wherein a length of the first fixed time period is longer than that of the second fixed time period.

4. The handheld device of claim 2, wherein the storage system is further operable to continuously cache the video and audio information recorded by the video and audio recording module, and store the video and audio information that happens within a third fixed time period.

5. The handheld device of claim 4, wherein the third fixed time period is equal to the first fixed time period subtracting the second fixed time period.

6. The handheld device of claim 5, further comprising a communication module operable to send a Save Our Ship (SOS) message to a hospital and to give a warning message to a driver of the vehicle.

7. The handheld device of claim 6, wherein the communication module is further operable to upload the video and audio information that happens within the second fixed time period to a network storage.

8. The handheld device of claim 1, wherein the abnormal situation of the vehicle comprises an unexpected driving of the vehicle and/or a traffic accident.

9. The handheld device of claim 8, wherein the signal generating module further comprises a speed sensor operable to monitor at least one of the unexpected driving of the vehicle and the traffic accident in real-time.

10. The handheld device of claim 1, wherein the unexpected driving of the vehicle comprises the vehicle running along an abnormal traffic route.

11. The handheld device of claim 10, wherein the signal generating module further comprises a global positioning system operable to determine locations of the vehicle.

12. A method for recording video and audio information of a vehicle in a handheld device, the method comprising:

continuously recording video and audio information of the vehicle, and storing the video and audio information that happens within a first fixed time period;

monitoring an abnormal situation of the vehicle in real-time; and

storing the video and audio information that happens within a second fixed time period when the abnormal situation of the vehicle occurs in a storage system of the handheld device, wherein the video and audio information that happens within the second fixed time period is not covered by video and audio information subsequently recorded by the video and audio recording module.

13. The method of claim 12, further comprising:

setting the first fixed time period, wherein the first fixed time period is a fixed time period before a current time, the current time is the time of the abnormal situation occurs; and

setting the second fixed time period, wherein the second time period is a fixed time period having two equal length time period, one half time is the time period before the time of when the abnormal situation occurs, and the second half time is the time period after the time of when the abnormal situation occurs;

wherein a length of the first fixed time period is longer than that of the second fixed time period.

14. The method of claim 13, further comprising:

continuously caching the video and audio information recorded by the video and audio recording module, and storing the video and audio information that happens within a third fixed time period.

15. The method of claim 14, wherein the third fixed time period is equal to the first fixed time period subtracting the second fixed time period.

16. The method of claim 15, further comprising:

sending a Save Our Ship (SOS) message to a hospital and giving a warning message to a driver of the vehicle when the abnormal situation of the vehicle occurs.

17. The method of claim 16, further comprising:

uploading the video and audio information that happens within the second fixed time period to a network storage.

18. The method of claim 17, wherein the abnormal situation of the vehicle comprises an unexpected driving of the vehicle and/or a traffic accident.

19. The method of claim 18, wherein the block of monitoring an abnormal situation of the vehicle in real-time comprising:

monitoring at least one of the unexpected driving of the vehicle and/or a traffic accident in real-time by way of a speed sensor; and

monitoring locations of the vehicle so as to determine where an abnormal traffic situation occurs by way of a global positioning system.
