Detailed Description
The embodiments of the present invention are further described below with reference to the drawings.
The first embodiment is as follows:
as shown in fig. 1, the present invention provides a traffic accident rescue system based on big data, which comprises the following modules:
the road danger state judging module is used for detecting whether a mobile terminal of a user is in a riding mode, if so, starting an acceleration sensor and a voice detector of the mobile terminal, and detecting acceleration and voice input signals in the riding mode; if the instantaneous acceleration of the mobile terminal is greater than a preset value or the voice detector detects a preset voice signal, the user enters a road danger state; it should be noted that, for example, the riding mode may be a bicycle riding mode or an electric bicycle riding mode, and since the speed of the mobile terminal carried by the user in the riding mode is maintained within a specific range, it may be detected whether the mobile terminal is in the riding mode through the movement speed of the mobile terminal. The acceleration sensor user detects the acceleration of the mobile terminal in the riding mode to judge whether the user maintains a normal riding state; for example, when the absolute value of the acceleration of the mobile terminal of the user at a certain moment is larger than the maximum acceleration range that can be applied by a person, it indicates that the user has suffered a large external force impact during riding, and at this time, there is a high possibility that the user is collided by another vehicle, and it is determined that the user has a traffic accident, that is, the user enters a road danger state. Similarly, the voice detector is used for detecting whether a user detects that the user of the mobile terminal sends a specific voice instruction in the riding mode, so as to judge whether the user maintains a normal riding state; for example, the user sends out voice information such as "save", "save me", "do not run", and at this time, it is determined that the user has a traffic accident, that is, the user enters a road danger state. Illustratively, the voice detector is a microphone of the mobile terminal.
The monitoring video acquisition module is used for sending the position information and the alarm information of the mobile terminal to a traffic information supervision server by the mobile terminal; after receiving the alarm information, the traffic information supervision server sends a monitoring video acquisition instruction of a preset time period before the sending time of the alarm information to a driving recorder of a vehicle and a road video monitoring camera device within a first preset radius distance by taking the position as a circle center; it should be noted that, the traffic information monitoring server user records urban road traffic information, and not only connects with traffic monitoring equipment, such as a road camera, and stores the video information of road traffic collected by the camera, but also authorizes the vehicle camera such as a vehicle data recorder connected with the vehicle, that is, obtains real-time traffic information of the road in a static and dynamic dual mode. In addition, the position information of the vehicle-mounted camera is also recorded in the traffic information supervision server at the same time. The alarm information is received by the traffic information monitoring server and then sent to a traffic guidance center, such as 110, in real time. After receiving the position information, the traffic information supervision server obtains video information acquired by a peripheral static and dynamic camera device by taking the position of the mobile terminal as a circle center, for example, the first preset radius is 10 meters; i.e. traffic conditions within a distance of 10 meters around the user; and in order to completely record the traffic state in the time period, the time period of monitoring video acquisition of the camera device is a preset time period before the sending time of the alarm information.
And the alarm module is used for sending the video to the traffic information monitoring server after the automobile data recorder and the road video monitoring camera device receive the monitoring video acquisition instruction, the traffic information monitoring server automatically identifies the video, and if the road traffic abnormity occurs, an alarm signal is sent to the road traffic alarm platform and the emergency contact of the user. It should be noted that, because the static and dynamic camera devices have established a communication connection with the traffic information monitoring server in advance, after receiving a video request instruction, the vehicle event data recorder and the road video monitoring camera device send the video to the traffic information monitoring server; the traffic information monitoring server automatically identifies whether a road traffic accident occurs in the video, and the method for judging whether the road traffic accident occurs in the video is realized by adopting an image processing algorithm known in the art, which is not described herein again. If the road traffic is abnormal, an alarm signal is sent to the road traffic alarm platform; the alarm signal at this point may also include transmitting a rescue signal 120.
The invention provides a traffic accident rescue system based on big data, which identifies whether a user is in dangerous states such as traffic accidents by recording driving characteristic information or voice information of a riding user, and then automatically calls a driving recorder or a traffic camera device around the user to record traffic conditions, so that the system can give an alarm timely according to the traffic conditions to ensure the personal safety of the user, records the traffic condition information so as to facilitate responsibility confirmation, and improves the timeliness and objectivity of road accident rescue.
As a preferred embodiment, the detecting whether the mobile terminal of the user is in the riding mode specifically includes:
detecting whether the movement speed of the mobile terminal is greater than a preset first speed threshold value and a preset second speed threshold value, if so, detecting the duration of the movement speed, and if the duration of the movement speed is greater than the preset time threshold value, enabling the mobile terminal to enter a riding mode. It should be noted that, in this embodiment, a speed determination method is used to determine whether the user enters the riding mode, for example, a normal riding speed is 10 to 20 km/h, illustratively, the first speed threshold is 8 km/h, and the second speed threshold is 22 km/h; if the movement speed of the user is within the two speed threshold ranges, the user may enter a riding mode; in order to ensure the accuracy of the judgment, a time threshold value is set, which is 1 minute as an example; at this time, the duration time of the movement speed is detected under the condition of maintaining the speed range, and if the duration time of the movement speed is greater than a preset time threshold value for 1 minute, the mobile terminal is judged to enter a riding mode.
As a preferred embodiment, if the instantaneous acceleration of the mobile terminal is greater than a preset value or the voice detector detects a predetermined voice signal, the user enters a road hazard state, further comprising:
if the instantaneous acceleration of the mobile terminal is larger than a preset value and the average speed of the mobile terminal after the instantaneous acceleration in a preset time period is zero, the user enters a road danger state; it should be noted that, for example, when the absolute value of the acceleration of the mobile terminal of the user at a certain moment is larger than the maximum acceleration range that can be applied by a person, it indicates that the user has suffered a huge external force impact during the riding process, and at this time, there is a high possibility that the user is collided by another vehicle; in order to further improve the accuracy of judgment, a user can fall down after receiving the impact under the conventional condition so as to maintain the speed at 0; thus, the average speed of a preset time period after the instantaneous acceleration is zero, for example, the average speed of 30 seconds of the preset time period is 0.05 m/s, i.e., the speed is almost 0; at this time, it is determined that the user has a traffic accident, that is, the user enters a road danger state.
Alternatively, the first and second electrodes may be,
and if the voice detector of the mobile terminal detects a voice signal and recognizes that a preset keyword exists in the voice signal, the user enters a road danger state. For example, the user sends out voice information such as "save", "save me", "do not run", and at this time, it is determined that the user has a traffic accident, that is, the user enters a road danger state.
As a preferred embodiment, the method further comprises:
the traffic information supervision server is a big data server; it should be noted that the big data server is connected to a plurality of servers to obtain all the monitoring videos of the urban road.
The traffic information monitoring server stores authentication information of a plurality of automobile data recorders, wherein the authentication information comprises owner identity information and vehicle identity information; after the authentication, the traffic information monitoring server has the authority to acquire the video information recorded and stored by the automobile data recorder. It should be noted that, in order to ensure the user privacy and data security of the vehicle owner, the traffic information monitoring server needs to obtain authorization and authentication before acquiring the video information of the automobile data recorder; meanwhile, in order to identify the video acquired by the vehicle, the owner identity information and the vehicle identity information need to be acquired at the same time. After the authentication, the traffic information monitoring server has the right to acquire the video information recorded and stored by the automobile data recorder in real time.
As a preferred embodiment, the traffic information monitoring server automatically identifies the video, and if a road traffic abnormality occurs, sends an alarm signal to a road traffic alarm platform, and further includes:
the traffic information supervision server automatically identifies the video, and if the occurrence of road traffic abnormality is not identified, the traffic information supervision server sends a monitoring video acquisition instruction of a preset time period before the alarm information sending time to a driving recorder of a vehicle and a road video monitoring camera device within a second preset radius distance by taking the position as a circle center; the second preset radius distance is greater than the first preset radius distance; it should be noted that, the first preset distance radius realizes a result of rapidly recognizing a road traffic accident by acquiring fewer videos, however, in order to ensure accuracy of the recognition result, under the condition that no road traffic abnormality is recognized within the first preset distance radius, a recognition radius in a larger range is set, so as to further ensure accuracy of the recognition result and avoid misjudgment. For example, the second predetermined radius is 50 meters or 100 meters.
And after receiving the monitoring video acquisition instruction, the automobile data recorder and the road video monitoring camera device send the video to the traffic information monitoring server, and the traffic information monitoring server automatically identifies the video. It should be noted that, because the static and dynamic camera devices have established a communication connection with the traffic information monitoring server in advance, after receiving a video request instruction, the vehicle event data recorder and the road video monitoring camera device send the video to the traffic information monitoring server; the traffic information monitoring server automatically identifies whether a road traffic accident occurs in the video, and the method for judging whether the road traffic accident occurs in the video is realized by adopting an image processing algorithm known in the art, which is not described herein again. If the road traffic is abnormal, an alarm signal is sent to the road traffic alarm platform; the alarm signal at this point may also include transmitting a rescue signal 120.
As a preferred embodiment, the method further comprises:
and after receiving the monitoring video acquisition instruction, the automobile data recorder and the road video monitoring camera device between the second preset radius distance and the first preset radius distance send the video to the traffic information monitoring server, and the traffic information monitoring server automatically identifies the video. It should be noted that, at this time, only the video information between the second preset radius distance and the first preset radius distance is identified, and the video information within the first preset radius is not repeatedly identified, so that the number of video identifications is reduced, and the efficiency of video identification is improved.
As a preferred embodiment, the traffic information monitoring server automatically identifies the video, and if a road traffic abnormality occurs, sends an alarm signal to a road traffic alarm platform, specifically including:
the traffic information supervision server automatically identifies the videos sent by the automobile data recorder and the road video monitoring camera device;
if the collision of the vehicles occurs in the video, identifying that the road traffic abnormity occurs; it should be noted that the method for determining whether a collision of a vehicle occurs in a video is implemented by using an image processing algorithm known in the art, and details are not described herein.
And recording the video with the road traffic abnormity and the time point information thereof, sending the information to a road traffic alarm platform, and sending out an alarm signal. It should be noted that, by recording the time point, the traffic police can analyze the accident reason conveniently.
The invention provides a traffic accident rescue system based on big data, which identifies whether a user is in dangerous states such as traffic accidents by recording driving characteristic information or voice information of a riding user, and then automatically calls a driving recorder or a traffic camera device around the user to record traffic conditions, so that the system can give an alarm timely according to the traffic conditions to ensure the personal safety of the user, records the traffic condition information so as to facilitate responsibility confirmation, and improves the timeliness and objectivity of road accident rescue.
