Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawing illustrated embodiment.
Give the traffic events detecting device by rig camera on the road with the transmission of video images of traffic circulation situation, event detector adopts on multiple goal identification and the detection technique identification highway and stops, reversing, drive in the wrong direction, low speed or drive over the speed limit, emphasis illegal activities such as changing Lane violating the regulations, and send affair alarm in Surveillance center.Event detector links to each other with information issue controller by 232 data lines, detected incident sent on the information issue controller in the mode of 8 binary codes (only the detected result of illegal activities that exists is sent to information issue controller), information issue this moment controller can generate early warning information and management and control measure automatically.Concrete management and control measure mainly is the management and control of propagandaing directed to communicate of long distance wireless loudspeaker, and simultaneously, system sends alarm sound prompting keeper, and generation man-machine conversation frame, then, the keeper accesses the incident video and the observation matrix screen is confirmed event type, and whether decision issues this event information and early warning information.Incident is in case affirmation is issued, and the managerial personnel of Surveillance center can implement to propaganda directed to communicate management and control to on-the-spot illegal vehicle by wireless speakers, can effectively prevent the generation of traffic hazard and improve the ability of handling accident.Simultaneously, information such as presented event type and early warning information on the LED display of wireless information release system provide management and control and early warning information for illegal vehicle and follow-up vehicle.
Embodiment:
Described monitoring and early warning system adopt following configuration:
Road traffic accident detecting device: epoch No. one; Information issue controller: HLINFO remote information promulgating system; Wireless information release system: LED display HL320-2, control system Hlight2.0 and gsm module; Long-range propagandaing directed to communicate: transmitter XW168C, receiver XW50W, typhon 25-19B; Warning device: 15w loudspeaker
Rig camera is connected by video line with event monitor, event monitor is connected with information issue controller by 232 data lines, LED display is communicated by letter with information issue controller by GSM in the wireless information release system, and the SIM card interface of LED terminal is the 3VSIM card.Rig camera sends to event detector with the video image of traffic circulation situation, determine the current overspeed of vehicle that exists according to multiple goal identification and detection technique identification, pre-define the respective code of different unlawful practices in the event detector, for example 0,000 0000 expression is driven in the wrong direction, 0,000 0001 expression illegal parking, 0,000 0010 is represented low speed driving etc., with the vehicle illegal parking is example, after event detector detects the vehicle illegal parking, event detector is sent to code 0,000 0001 on the information issue controller, the affair alarm of Surveillance center's issue simultaneously.Information issue controller generates corresponding early warning information and management and control measure automatically according to code, (general early warning information and management and control measure are pre-set in information issue controller, and it is corresponding with respective code, that is to say that information issue controller receives after the code, accesses corresponding early warning information and the management and control measure that configures automatically according to this code.) produce the man-machine conversation frame simultaneously, can further set prompt tone and note to remind the keeper.The keeper has access to the associated video image with further affirmation incident according to information shown on the man-machine conversation frame, thereby whether decision issues early warning information.If the keeper confirms this incident, then show this incident at long-range variable information plate, the issue corresponding information provides safety instruction for follow-up vehicle, reminds preceding vehicle to have illegal parking to it, takes care.
Characteristics of the present invention are mainly reflected in the following aspects:
1, highway emphasis illegal activities monitoring and early warning system are big system integrations, comprising: road traffic accident detecting device, information issue controller, wireless information release system, long-range propagandaing directed to communicate and warning device etc.This system with emphasis illegal activities detection and monitoring, incident storage and differentiation, the generation automatically of early warning prediction scheme, wireless telecommunication, early warning information show in real time, function such as long-range traffic administration management and control is integrated, the whole process of generation, development, dissipation of highway emphasis illegal activities is carried out whole process control in real time, guaranteed the orderly running of a series of links such as incident discovery, information issue, enforcement management and control, effectively prevented the generation of traffic hazard and reduce the influence of emphasis illegal activities traffic circulation.
2, the road traffic accident detecting device can be discerned the type of highway emphasis illegal activities automatically, and the video information before and after recording events takes place sends event information and encodes to information issue controller.Information issue controller receives the coded message of event detector, generates early warning information automatically, produces the man-machine interaction dialog box, confirms event information or revises relevant information for the keeper, and have wireless transmission early warning information function.Wireless information release system is made up of LED display and GPRS (CDMA) communication module, has radio communication function and high brightness and shows the early warning information function.Long-range propaganda directed to communicate and warning device can trigger the alarm managerial personnel of control center and have the emphasis illegal activities and take place when the traffic events detecting device is found incident confirmed to send the back when incident and triggered report to the police caution illegal vehicle and the obedience traffic control of follow-up vehicle and drive with caution in that monitored space is on-the-spot; The managerial personnel of Surveillance center can implement the traffic administration management and control to on-the-spot illegal vehicle and follow-up vehicle by long-range the propagandaing directed to communicate of wireless speakers, take the early warning measure in real time.
3, native system to highway modal, the most serious, the easiliest cause the emphasis illegal activities of rear-end collision to be monitored and early warning, can realize average event detection time of fire alarming≤10 seconds, verification and measurement ratio 〉=90%, storage event information 6 minutes (incident front and back takes place each 3 minutes), early warning response cycle≤20 second, long-range traffic administration management and control zone radius≤30Km, incident is on average eliminated time≤1 minute, can avoid highway because of the traffic hazard of stopping, reversing, emphasis illegal activities such as drive in the wrong direction produce effectively.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the embodiment here, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
