Description of the Invention: [Technical Field] The present invention provides an instantaneous driving road condition monitoring system, and more particularly to a monitoring system capable of simultaneously recording road condition video, vehicle operation information, and vehicle position. [Prior Art] Since the invention of the automobile, the probability of occurrence of traffic accidents has also increased with the increase of the number of vehicles. The causes of traffic accidents are mostly caused by human error or violation of traffic. However, accidents are mostly sudden, traffic accidents. The parties often have disputes because they cannot grasp the accident site information. If the accident two vehicles are equipped with a driving recorder, it can help to clarify the responsibility for traffic accidents. With the advancement of technology, the driving recorder has evolved from the original mechanical to the current electronic version. However, the existing electronic driving recorder still focuses on storing vehicle operation information such as speed, braking, driving direction, etc., and cannot fully scale the car: if the electronic vehicle detection device is added, such as driving image driving Location and route and other related vehicle operation information, then the surname of the other-synchronized integration of the contact, this position from these digital vehicle operation information is obtained by the side of the signal processing ride, and the individual number of positions _ If the financial system is established (4), if it is not coordinated, it will be difficult to synchronize the driving information with the location signal processing of the riding ship. With the 'should be needed' set, it can accurately record the road condition video, the vehicle running Beixun and the car's immediate driving road condition monitoring. Step 1314111, but this problem can be solved by the synchronous clock counter 14 of the present invention; in particular, the synchronous clock counter 14 can send a sync count signal with an accuracy of i/ioo seconds and 16 bits. Each count of 65536 times (about u minutes) will be reset to zero, when the 16-bit sync count signal is added to the front end of the GPS satellite positioning signal and the OBD-II diagnostic signal, and the GPS positioning signal and OBD are added. The -II diagnostic signal is encapsulated in a special packet format. The packet definition is as shown in the second and third figures. The GPS and OBD-II header id default values are 0x01 and 0x02, respectively, and the packet length flag uses 2 bits. The Byte is used to record the effective length of the subsequent GPS satellite positioning signal and the obd-II diagnostic signal. The maximum length of the preset GPS satellite positioning signal and the 〇BD-II diagnostic signal is 1200 bytes, and the total length of the packet is 1200 bytes. The degree is 12〇5 bytes; at the same time, the 16-bit synchronous counting signal is also sent to the dynamic video encoder to be synchronized with the GPS receiver and the OBD-II diagnostic instrument, that is, each dynamic video encoder The output video compression frame will Packed in the packet format shown in Figure 4, the default value of the file header ID is 〇x〇3. After that, the dynamic video packet will be synchronized with the GPS and OBD-II packets. The pairing method will be The GPS or OBD-II packet with the same counting signal is embedded in the User Data of the dynamic video data. After the synchronization integration, all the synchronization counting signal fields of the packet will be removed, and Output a single bit string. As shown in the first figure, the onboard host system further includes a 3G network module 16 through which the upper right corner 43 of the mobile host 11 can be integrated. Driving route map, the upper left corner is the _ instant driving video (not shown) recorded by the camera 31 and the bottom = 'user can drag and drop to adjust the playing time, fast forward or reverse. According to this day's real-time driving condition monitoring system, the system can provide two modes of making and offline browsing, among which, it is difficult to take 1 to the light on the line, and the machine is 2, the input is simple, the secret, the 彳(10)t_lng) Forms receive traffic monitoring in ', φ ^ Gps - Π diagnostic news, etc., and respectively video, graphics, dynamics:: multi: _ type broadcast; away from the _ view is from the memory card to draw driving L Tiger' Its Weis on the _ mode is the same. = The instant traffic condition monitoring system constructed by the invention can record the position of the vehicle synchronously except for the state of the vehicle: ==::## is in the memory card, or through the _ device (two = hand Γ: The computer, personal digital assistant 愔, +_ mobile phone 'execute the driving dynamics browser to read the record can be based on the age-old car information, or connected to the driving monitoring center host, can also master the vehicle Driving dynamic information. The real-time driving road condition monitoring system provided by the month has extremely high closing value for vehicle anti-theft, 11 1314111 vehicle long-distance turn, and the traffic accident of the vehicle. The driving _ information_viewer can be used to anti-Weicha, adjust the speed of the crane, which is conducive to the cause of the accident in the accident of the accident, and the clarification of the responsibility of the accident, and when there is an accident or a transfer, you can call for help through the 3G mobile phone. Record and alarm, report the location and date of the accident after the accident, (4) provide first aid measures for the injured person or eliminate the vehicle fault, and can be applied to vehicle anti-theft and crime detection. The foregoing is a better implementation of the present invention. For example, the embodiment of the present invention can be modified or modified in various ways. For example, the host on the vehicle is not limited to making the SD SD pin 15 a domain plane, and can also be used as a hard surface. Others, such as discs, optical discs, flash memory, and the like, are apparently replaced and modified by those skilled in the art and will still be incorporated in the scope of the claimed invention.
