* Monitoring scheme

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, can transmit panoramic view, greatly improved work efficiency, And can find the situation at that time, for * decision-making to provide accurate, timely, 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 product selection requirements and functions, and estimate the whole project cost for the implementation of the scheme.

Two, design requirements

1. Using the world's most advanced computer full digital compression monitoring system and the combination of traditional monitoring system, forming 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 site.

3. The system should use the computer digital hard disk to record the image in full real-time, clear and without omission.

4. The system has scalability. The system has high reliability, long service life and easy maintenance.

Computer monitoring system

Computer monitoring system is a kind of image monitoring application technology for security prevention and management. Collect valuable image information to understand the decision-making conditions of emergencies. At the same time, to record the event, 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 in the computer hard disk through the digital compression technology, and the monitored object is automatically and continuously recorded. The stored image will be automatically deleted after the hard disk is full. According to the worksheet set by the user, the system will automatically cycle, without manual intervention, to achieve full automatic management, and fundamentally realize unattended. Once the system encounters a power failure, it can automatically resume work.

The system can retrieve and play back the stored image conveniently and in real time at any time. It can retrieve and play back the image according to time and camera. Due to the adoption of advanced digital processing technology, the image display quality is higher, the playback image is stable, clear, can be read and written repeatedly, there is no traditional monitoring system exists in the video signal attenuation and wear problems, and do not need to buy and save a large number of video. The system overcomes the deficiency of traditional system, has good man-machine interface, makes the operation more simple and easy to learn, more intuitive, more easy daily maintenance.

The system can be networked via an existing LOCAL area network and connected to other computers, who can view and control the monitoring system according to their priorities. The control system of hyperchamber adopts a series of multi - channel digital hard disk monitoring system. The system integrates multi-screen display, image compression coding/restoration decoding, digital video/real-time playback, image backup/restoration and camera alarm control, which can meet the comprehensive functional requirements of modern security. Full Chinese menu setting and multi-function operation (monitoring display, video saving, search playback, image backup, network transmission and camera control synchronization), so that the operation is very simple; Mpeg-1 compression technology and motion detection technology are used to reduce the average amount of frame data and save the disk capacity. The intelligent search function makes it very simple and quick to replay the event image, which greatly reduces the search time. Users can use LAN for network storage, image playback, lens control, can form a network of 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 the * into 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 miniaturization, high performance and low power consumption. The improvement in performance is reflected in high definition, intelligent backlight processing, automatic color gray compensation, electronic zoom and so on. With the rapid development of electronic technology in today's society, technology brings forth the new from the old, and the replacement of the old and the new is accelerated, it is difficult to maintain the advanced advantages of any system for a long time. Therefore, in the selection of equipment, we should consider the practicability and reliability, but also consider the maintainability of the system.

The camera holder control enables one camera to observe multiple directions. The accessories include a holder to control the observation direction and a zoom lens to focus the objects observed at different depths of field. The camera adopts 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-way computer digital hard disk video recorder will be used to record 75 frames per second on the hard disk, so that the playback in the picture will be full real-time, in order to ensure the high integrity of the recorded image.

In the image display aspect, a 17 "color monitor is used to display 16 images respectively to monitor the situation of the whole area.
