Description
Technical field
The present invention relates to video teaching technical field, particularly for research and development experimental provision and the control method thereof of traffic video monitoring.
Background technology
Along with the fast development of urban economy, the sharp increase of urban automobile quantity, traffic accident continues to occur, and road monitoring becomes the important urgent part of urban traffic safety management.At present, video monitoring apparatus only can realize recording and the storage of monitor video, cannot realize the Treatment Analysis of video monitoring image and carrying out of follow-up R&D work.
From the technical point of view, video monitoring system developing history comprises: first generation video monitoring system (CCTV), the second generation is based on " PC+ multimedia card " digital video monitor system (DVR), the complete IP based network video monitoring system (IPVS) of the third generation, and the DVS between the second generation and the third generation.
First generation video monitoring CCTV, the closed-circuit TV monitoring system mainly based on analog machine, image information adopts vision cable, transmit in an analog fashion, general transmission range can not be too far away, and be mainly used in the monitoring among a small circle, monitoring image generally can only be checked by the heart in the controlling.Supervisory control system is primarily of compositions such as video camera, video matrix, monitor, video tape recorders, video transmission line is utilized to be connected on monitor by the video from video camera, utilize host computer of video matrix, adopt keyboard to carry out switching and controlling, video tape recorder uses the video recording of tape.And remote image transmission adopts analog optical fiber, optical transmitter and receiver is utilized to carry out the transmission of video.
The shortcoming of first generation video monitoring CCTV is as follows:
1, the transmission of limited analog video signal is adjusted the distance very responsive;
2, limited simulation video monitoring cannot be networked, and can only monitor scene in a point-to-point fashion, and makes wiring installation amount very big;
3, the storage medium (as video tape) of the storage meeting at substantial of limited analog video data signal, very loaded down with trivial details during inquiry evidence obtaining.
The second generation " PC+ multimedia card " digital video monitor system (DVR) function is comparatively strong, and being convenient to execute-in-place, is the supervisory control system of half simulation Semi-digital type.Several video cameras, various detection and alarm probe and data equipment is had at far-end, obtain image information, by respective transmission line tandem to multimedia monitoring terminal as on PC or Industrial Control Computer, and then by communication network, these information are passed to one or more Surveillance center.
The second generation " PC+ multimedia card " digital monitor system shortcoming:
1, stability is bad, and video front (as the collection of the vision signals such as CCD, compression, communication) structure is comparatively complicated, and reliability is not high;
2, power consumption high, costly, need many people guard on duty;
3, software opening is bad, limited transmission distance.
Extension-DVS the feature of " analog to digital " supervisory control system (DVR) between the second generation and the third generation, as:
1, with the digitalized network video monitoring system that online video server and video synthesis management platform are core;
2, the analog video signal that video camera exports is directly changed into IP digital signal by Embedded Video Codec, is directly connected into Ethernet, the cable saving various complexity connects, have convenient, flexible, namely insert the feature such as namely to see;
3, the independently hardware module such as embedded decoder, controller, recording service device is had;
4, DVS is the supervisory control system comparing main flow at present, and performance is more excellent, and price inexpensively.
The advantage of digital video monitor is as follows:
1, digitized video can in the upper transmit image data of computer network (local area network (LAN) or wide area network), and not by distance limit, signal is not easily disturbed, and can increase substantially image quality and stability;
2, digital video can utilize computer network to network, network bandwidth reusable, need not repeat wiring;
3, digitlization storage becomes possibility, and the video data through overcompression can be stored in disk array or be kept in CD, USB flash disk, query manipulation simple and fast;
4, installation work that need not be huge, reduces construction volume.
Third generation video monitoring: the video monitoring system IPVS using IP technology completely, with the remarkable difference of above-mentioned three kinds of schemes, specific as follows:
1, the built-in Web server of video camera, provides ether port, is integrated with various agreement in video camera, supports hot plug and directly accesses;
2, JPEG or the MPEG-4 data file that video camera generates can access, monitor, record and print for any authorized client computer any position from network, instead of generates continuous analog vision signal form image;
3, tool high-tech content, the 3G network by movement realizes wireless transmission and checks.
