Abstract

The present disclosure provides a method and a device for detecting whether an object violates a traffic signal. The terminal moving along with the object is in communication with the network to acquire the state of the traffic signal in the moving direction of the object; when the acquired state of the traffic signal is in the no-passing state, the terminal determines a current position of the object according to beacons surrounding the intersection where the object is; and then, the terminal moving along with the object detects whether the object violates the traffic signal according to the determined current position of the object.

Claims

1. A method for detecting whether an object violates a traffic signal, comprising:

acquiring, by a terminal moving along with the object, a current signal state of the traffic signal in a moving direction of the object through a network, the terminal being paired with the object;

determining, by the terminal, a current position of the object according to beacons surrounding an intersection where the object is in response to the current signal state of the traffic signal being no passing; and

detecting, by the terminal, whether the object violates a traffic signal according to the current position of the object;

wherein the step of the terminal determining a current position of the object according to beacons surrounding the intersection where the object is, comprises;

determining, by the terminal, beacons surrounding the intersection wirelessly, in response to the current signal state of the traffic signal being no passing;

determining, by the terminal, a distance from each beacon according the received signal strength of each determined beacon; and

determining, by the terminal, the current position of the object according to the distance from each beacon.

2. The method according to claim 1, wherein the object is a user or a transportation.

3. The method according to claim 2, wherein the transportation is a shared bicycle.

4. The method according to claim 1, wherein, after the terminal determines whether the object goes through traffic signal according to the current location of the object, the method further comprises:

sending, by the terminal, a warning message after the terminal determines that the distance between the object and the intersection is lower than a threshold corresponding to the type of the object and the object does not violate the traffic signal.

5. The method according to claim 4, wherein, after the terminal determines that the distance between the object and the intersection is lower than a threshold corresponding to the type of the object and the object does not violate the traffic signal, the method further comprises:

the object being a shared bicycle, controlling, by the terminal, a braking module of the shared bicycle in a wireless manner to slow the shared bicycle down according to a current acceleration of the shared bicycle.

6. The method according to claim 1, wherein, after the terminal detects whether the object violates a traffic signal according to the current position of the object, the method further comprises:

in response to the object violating the traffic signal, the terminal reports information with regard to violation of the traffic signal to a network side.

7. A device for detecting whether an object violates a traffic signal, the device being paired with the object and comprising:

at least one processing unit and at least one storage unit, wherein

the at least one storage unit stores program codes, which cause the at least one processing unit to perform the following steps when executed;

acquiring a current signal state of the traffic signal in a moving direction of the object through a network;

determining a current position of the object according to beacons surrounding an intersection where the object is, if the current signal state of the traffic signal is no passing; and

detecting whether the object violates a traffic signal according to the current position of the object;

wherein the at least one processing unit is configured to;

determine beacons surrounding the intersection wirelessly, if the current signal state of the traffic signal is no passing;

determine a distance from each beacon according the received signal strength of each determined beacon; and

determine the current position of the object according to the distance from each beacon.

8. The device according to claim 7, wherein the object is a user or a transportation.

9. The device according to claim 8, wherein the transportation is a shared bicycle.

10. The device according to claim 7, wherein the at least one processing unit is further configured to send a warning message after the distance between the object and the intersection is lower than a threshold corresponding to the type of the object and the object does not violate the traffic signal.

11. The device according to claim 10, wherein the at least one processing unit is further configured to, if the object is a shared bicycle, control a braking module of the shared bicycle in a wireless manner to slow the shared bicycle down according to a current acceleration of the shared bicycle.

12. The device according to claim 7, wherein the at least one processing unit is further configured to, if the object violates the traffic signal, report information with regard to violation of the traffic signal to a network side.

13. A non-transitory computer readable storage medium, storing one or more programs for execution by one or more processors, the one or more programs including instructions for:

acquiring a current signal state of the traffic signal in a moving direction of an object through a network;

determining a current position of the object according to beacons surrounding an intersection where the object is, if the current signal state of the traffic signal is no passing; and

detecting whether the object violates a traffic signal according to the current position of the object;

wherein the one or more programs further include instructions for;

determining beacons surrounding the intersection wirelessly, if the current signal state of the traffic signal is no passing;

determining a distance from each beacon according the received signal strength of each determined beacon; and

determining the current position of the object according to the distance from each beacon.

14. The medium according to claim 13, wherein the one or more programs further include instructions for:

sending a warning message after the distance between the object and the intersection is lower than a threshold corresponding to the type of the object and the object does not violate the traffic signal.

15. The medium according to claim 14, wherein the one or more programs further include instructions for:

if the object is a shared bicycle, controlling a braking module of the shared bicycle in a wireless manner to slow the shared bicycle down according to a current acceleration of the shared bicycle.

16. The medium according to claim 13, wherein the one or more programs further include instructions for:

if the object violates the traffic signal, reporting information with regard to violation of the traffic signal to a network side.
