An overview, Computer digital television monitoring system, is a concentration of real-time image and video monitoring, image processing, alarm, signal processing, multimedia technology and digital hard disk video is a body comprehensive monitoring management system, set up and use it, make the security staff and executives don't have to be on the ground, it can be the scene situation panoramic view, greatly improved work efficiency, and can find what happened afterwards, for the leadership decision-making to provide accurate, timely and effective information services. This scheme mainly according to the confirmed design requirements, design, and at the same time according to the requirement and basis of the site location, the equipment and the configuration of the control room and achieve the purpose of the design are combined to complete the design of the main body, at the same time, determine the main design basis, technical indicators of system, and console according to actual needs to carry on the design of computer room. According to the design, we describe the selection requirements and functions of the products, and estimate the cost of the whole project for the implementation of the scheme. II. Design requirements 1. The world's most advanced computer full digital compression monitoring system is combined with the traditional monitoring system to form a reasonable security closed circuit computer monitoring system. 2. The camera installed in the super room can clearly see the situation of the personnel on the scene. 3. The system should use the computer digital hard disk for full real-time video recording of image recording, clear and without omission. 4. The system is extensible. The system has high reliability, long service life and easy maintenance. III. Design Basis Code for Design of Industrial Television System Engineering (GBJ115-87) "Civil Closed-circuit Monitoring and Television Engineering Technical Code" (GB50198-94) Technical Code for Engineering Procedures for Safety and Prevention (GA/T75-94) Technical Code for Security Television Monitoring Engineering (discussion draft) "Code for Design of Grounding for Industrial Enterprises" (GBJ79-85) "Code for Construction and Acceptance of Grounding Devices for Electrical Installation Engineering" (GB50169-92) Four, computer monitoring system Computer monitoring system is a kind of image monitoring application technology used for security prevention and management. Collect valuable image information to understand the emergency decision conditions. At the same time, the event record, provide effective materials and evidence. 1. Control system Computer digital monitoring system of the monitoring system with traditional way of "analog" incomparable advantages, it used the high-performance PC, replaced the traditional "simulation" needed for the control system of a large number of monitors, video, images, video processor devices such as switches and matrix system, system simplification, and greatly improve the system of *. The image of the object taken by the computer digital monitoring system is recorded and stored in the computer hard disk through the digital compression technology, and the monitored object is automatically and uninterruptedly recorded. The stored image will be deleted automatically after the hard disk is full. The system according to the user set the worksheet, then automatic cycle, without manual intervention, to achieve full automation management, fundamentally unattended. Once the system encounters power failure, it can automatically resume work. The system can retrieve and playback the stored images conveniently and in real time at any time, and can retrieve and playback the images by time and camera. Due to the use of advanced digital processing technology, the image display quality is higher, the playback image is stable, clear, can be read and write repeatedly, there is no traditional monitoring system in the existence of the video tape signal attenuation and wear problems, and do not need to buy and save a large number of video tapes. The system overcomes the deficiency of the traditional system, and has a good man-machine interface, which makes the operation simpler and easier to learn, more intuitive, and easier for daily maintenance. The system can carry out network transmission through the existing local area network and connect with other computers. The computers on the network can watch and control the system according to the priority level. The control system of the super room adopts a series of multi-channel digital hard disk monitoring system. The system integrates multi-screen display, image compression coding/recovery decoding, digital video recording/real-time playback, image backup/restore and camera alarm control and other functions, which can meet the comprehensive functional requirements of modern security. Full Chinese menu setting and multi-function operation (monitoring and display, video saving, search and playback, image backup, network transmission and camera control synchronous), make the operation is very simple; MPEG-1 compression technology and motion detection technology are used to reduce the average frame amount of image and save the capacity of hard disk. The intelligent search function makes it very simple and fast to replay the event image, which greatly reduces the search time. Users can carry out network storage, image playback and lens control through the LAN, which can constitute a networked large-scale monitoring system. Can completely replace the traditional analog monitoring system of multiple processors, video recorder, video printers and other equipment, for a long time and the operation is simple, is *, long service life, the system cost and long-term management, maintenance cost is low, is currently the most advanced digital monitoring equipment, represents the direction of digital security technology development. 2. Camera configuration and performance At present, the structure and technology of camera tend to be small, high performance and low power consumption. The improvement in performance is reflected in high definition, intelligent backlight processing, automatic color grayscale compensation, electronic zoom, etc. With the rapid development of electronic technology in today's society, it is difficult to maintain the advanced advantage of any system for a long time. Therefore, in the selection of equipment, should consider the practicability and availability, but also should consider the maintainability of the system. Camera head control enables one camera to view multiple azimuths, and accessories include a head to control the direction of observation and a zoom lens to focus the observed object at different depths of field. The camera uses high definition color camera. 3. Image processing and recording In the design requirements of the system, it is emphasized that all images should be recorded in real time for viewing. In the design, a 16-channel computer digital hard disk video recorder will be used to record the hard disk at 75 frames per second, so that the playback of the picture will be full real-time, to ensure the high integrity of the recorded image. In the aspect of image display, a 17 "color display is used to display 16 images respectively, and the situation of the whole area is monitored comprehensively. V. Main product performance indexes System: Windows NT platform, stable operation can be * Multi-function, intelligent operation: monitoring/recording/playback/transmission/control can work in parallel, with high intelligence Real-time video display: each channel image real-time display, fully meet the requirements of on-site real-time monitoring, 4/6/8/9/10/12/16 screen display Real-time audio and video recording :4-16 channels audio and video real-time recording, audio and video synchronization is good Video motion detection: the detection area and sensitivity are set. Video recording can be performed automatically when there is a moving target in the detection area Compression mode: MPEG-1/M-JPEG DSP compression book, video speed of 25/30 frames/second |
