The signal that device, acceleration transducer and vibrating sensor are sent, that is, perform step S1.Then, believed according to the video received
The detection signal that breath or safety sensor are sent judges whether vehicle or vehicle front occur traffic accident, that is, performs step
Rapid S2.
For example, the video information received is identified the controller on the first prior-warning device, judge Current vehicle or
Whether person's vehicle front sends traffic accident.Or, controller is received after the detection signal that safety sensor is sent, if
Detection signal meets default condition, then directly judges that traffic accident occurs for Current vehicle.
Then, prior-warning device performs step S3, and the current position of the alarm signal and vehicle that occur traffic accident is believed
Breath is sent to cloud server in the lump.Cloud server is received after alarm signal, judges whether the place accuses for the first time
Alert signal, if the alarm signal sent for the first time, then to traffic alert, certainly, there is injury to personnel
In the case of, hospital etc. is informed about, so that the wounded is given treatment in time.In the present embodiment, due to the first prior-warning device
The video information of the scene of the accident is shot by camera device and cloud server is uploaded to, backstage personnel are according to cloud server
The video information of reception determines whether the situation of injury to personnel, then judges whether to need to notify hospital.
Certainly, the first prior-warning device to cloud server send alarm signal while, the on also peritropous vehicle
Two prior-warning devices send pre-warning signal, and for example passing signal by 2.4G number sends pre-warning signal.
Then, step S4 is performed, cloud server is received after alarm signal, sends the instruction for obtaining video information, the
Video information in the position correspondence period of one prior-warning device exception will occur situation is sent to cloud server, is taken by high in the clouds
Business device is analyzed video information and judges whether to occur unusual condition, is such as to determine generation unusual condition, then to sending announcement
The second prior-warning device on other vehicles in the vehicle-surroundings preset range of alert signal sends warning information.If taken by high in the clouds
Device be engaged in directly to the second prior-warning device transmission pre-warning signal, it is possible to cause the second prior-warning device can not because signal intensity is weaker
Timely receive in warning information, therefore the present embodiment, warning information is sent by signal transmitting base station.
For example, cloud server determines that base station occurs for a nearest signal of place where the accident occurred point, and sent out to the signal
Penetrate base station and send warning information, the second prior-warning device on the peritropous vehicle of signal transmitting base station sends warning information.Cause
This, signal transmitting base station is received after warning information, and the second prior-warning device performed on step S5, peritropous vehicle sends pre-
Alert information.Because the signal that each signal transmitting base station is sent can only cover certain scope, such as 300 meters or 500 meters,
Therefore the second prior-warning device on the peritropous vehicle of signal sent by signal transmitting base station sends signal, it can be ensured that only
There is the second prior-warning device within a predetermined range just to receive pre-warning signal.Also, because signal transmitting base station is arranged on distance
The not far place in ground, the intensity of the signal sent is higher, and on the vehicle therefore, it is possible to ensure place where the accident occurred point periphery
Two prior-warning devices can in time, effectively receive pre-warning signal.
Second prior-warning device is received after warning information, immediately perform step S6, alert, such as by LED,
Generating laser sends light beam, or sends audible alarm information by buzzer, so as to nearby vehicle human pilot short
Warning message is received in time.
Certainly, background work personnel can be engaged in the dialogue by cloud server with the personnel in vehicle, such as first
Microphone, loudspeaker etc. are set on prior-warning device, and the personnel of the first prior-warning device can be taken by microphone, loudspeaker and high in the clouds
The background work personnel of business device engage in the dialogue, so as to allow background work personnel to understand the injury to personnel feelings of vehicle in a short time
Condition, is conducive to carrying out urgent rescue processing.
If communication function accident has been disposed, the department on the first prior-warning device or the second prior-warning device vehicle multiplies
Personnel can press the button for cancelling early warning, so as to send the information for cancelling early warning to cloud server, cloud server is immediately
Cancellation sends warning information.Certainly, cloud server can also be by receiving the first prior-warning device or the second prior-warning device institute
The video information of transmission, is analyzed received video information, judges whether traffic accident has been disposed.And or
Video information of the controller according to captured by camera device on person, the first prior-warning device or the second prior-warning device is automatically analyzed
Whether traffic accident has been disposed, if traffic accident has been disposed, and sends and cancels from trend cloud server
The information of early warning.
Therefore, cloud server performs step S7, judges whether to receive the instruction for cancelling early warning, cancels the finger of early warning
Order can be that the first prior-warning device or the second prior-warning device are pressed and cancel the signal or cloud service of early warning button
Device judges that instruction or first that traffic accident has been disposed and sent automatically are pre- according to the video information received
Alarm device or the second prior-warning device controller of itself judge that traffic accident has been handled according to received video information
The instruction for finishing and being sent to cloud server.
Finally, cloud server performs step S8, and cancellation early warning is sent to the first prior-warning device and the second prior-warning device
Information, for example, directly sending the information for cancelling early warning to prior-warning device, or cancellation early warning sent by signal transmitting base station
Information.When the first prior-warning device or the second prior-warning device, notice sends warning information, for example, stop sending audible alarm letter
Breath stops sending warning information by light.
It can be seen that, during practical application, as shown in fig. 7, in processing normally travel stage, i.e. the S11 stages, the first prior-warning device is not
Pre-warning signal can be sent, once there is the very short time after unusual condition, i.e. S12 moment in generation traffic accident or road
It is interior, that is, to be inscribed in S13, the first prior-warning device will receive the signal that safety sensor is sent, and to cloud service
Device 32 sends alarm signal, for example, alarm signal can be sent by the signal transmitting base station 34 on periphery, or directly to high in the clouds
Server sends alarm signal, and after occurring unusual condition 1 second, i.e. at the S14 moment, the first prior-warning device can be with peritropous vehicle
Send pre-warning signal, such as send pre-warning signal to the vehicle in 500 meters of periphery.
Cloud server 32 i.e. the S15 moment, will receive alarm signal, and send acquisition video information after 3 seconds
Instruction, cloud server 32 receives video information after the S16 moment, that is, occur unusual condition 8 seconds, so as to judge that road is
No generation unusual condition, once judging occur unusual condition, is sending relief information, responding agencies can be 20 to responding agencies
Relief information is received after second, i.e., in S17 receptions to succouring information, the responding agencies such as fire-fighting, public security, hospital can be with
Respond at once, the vehicle on periphery can start to rescue nearby behind S18 moment, i.e., 180 second, and professional rescue department can be 300
After second, i.e. the S19 moment reaches the spot expansion rescue work.
Certainly, the first prior-warning device can also be pointed out and positioned to the vehicle of hit-and-run, for example, according to shooting
The signal that device and safety sensor are received judges that vehicle collides and there occurs traffic accident, if vehicle does not have
Stop in time, and be to continue with traveling, then the first prior-warning device sends voice message, point out driver to stop in time.If driven
Personnel do not stop and are to continue with traveling, then send signal to the control system of vehicle, progressively close the control loop of vehicle, cause
Vehicle safety is set to stop.For example, setting senior drive assist system (ADAS) on vehicle, the first prior-warning device drives with senior
Accessory system communicates and is used in combination, and when needing to close the control loop of vehicle, can pass through senior drive assist system
Closing progressively, for example, progressively close off throttle, and the speed of control vehicle is gradually reduced.
It can be seen that, can be by road safety early warning system to generation when the unusual condition such as traffic accident occurs for road
The nearby vehicle of traffic accident sends warning information, and can notify the rescue such as traffic police, hospital, fire department, law enforcement at once
Department, effectively improves traffic accident disposal efficiency, ensures the unimpeded rate of road, because when reduce the generation of traffic accident.
