I. Introduction With the rapid development of economic level and science and technology, people have higher and higher requirements for safety precautions. In order to deal with various economic criminal crimes, protect the safety of life and property of the country and the people, and ensure the normal operation of all walks of life and key national departments, the use of high-tech means to prevent and suppress crime has become a consensus in the security field. In recent years, with the introduction of various new security concepts abroad, various industries have begun to establish closed-circuit television monitoring systems or alarm networking systems. Especially in the judicial, banking, communications, postal savings, electricity, and entertainment and Internet cafes, shopping malls and other places that are increasing rapidly with Japan, the establishment of a networked alarm system will play a huge role in preventing and stopping crime and maintaining social stability. However, the traditional video surveillance and alarm networking systems were limited by the level of technological development at that time, and most of the television surveillance systems could only be monitored on the spot. In addition, the traditional analog image monitoring system with a video recorder as the core exposes various hidden dangers, such as: the video recorder often fails, the video tape image is blurred, the video tape cannot be stored for a long time, and the video recording is inconvenient and management is inconvenient. Less than the user's requirements. At present, with the popularization and application of computers, the rapid development of network communication technology and image compression processing technology, the use of the latest computer, communication, image processing technology, and the transmission of digital images through network lines can provide high-efficiency, feasible and affordable prices for remote image monitoring. Cheap solution. 2. Brief introduction of digital monitoring system: Computer digital monitoring system is a new product in the monitoring and alarm industry. It combines digital video image recording with multi-screen image display and monitoring and alarm functions. It will gradually replace traditional analog multi-screen splitters and long-term video recorders. It is flexible and convenient. Features. On this basis, high-end industrial control microcomputers, PC workstations or PC servers are used to increase the number of camera image input channels, increase the display rate of multi-screen images, increase the control functions of the gimbal and lens, and match them with good people The computer interactive interface constitutes a digital monitoring and alarm system with the computer as the core. The system structure is shown in the figure: 3. Main functions of computer digital monitoring system: 1. Select the image of the input camera 2. One or more channels can be selected from the input images of multiple cameras on the screen 3. Use hard disk to digitally record images 4. The digital hard disk storage and video decompression function can completely record the high-definition picture of the camera, so that the picture can also achieve extremely high definition during playback 5. The key to evaluating the performance of multi-screen split display is the image processing and display update speed and the clarity of the screen. Control the movement of the gimbal and lens 4. Main features of the system ? High reliability: The system adopts a modular design to fully ensure that the system can be operated without interruption and safety during expansion and upgrade, that is, it can be modified and maintained under the system's operating state. Centralized monitoring: The system can not only carry out complete centralized monitoring of the status information, alarm information, control commands, image information, etc. of various power equipment, environmental equipment and systems in a single computer room, but also implement multiple computer rooms distributed around Centralized monitoring and management across regions. ? Duty management: Taking into account that the staff on duty may not implement monitoring management 24 hours a day to prevent accidents. When there is an abnormal situation, the system automatically informs the staff on duty by sending an alarm message, etc., to provide the possibility of unmanned or less-mannered modern computer room management. ? Remote management: The administrator can conveniently check the running status of the equipment and system in each computer room remotely through any terminal, and control and manage the system if the permission allows. ? Log management: The system automatically records the operator, operation content, operation time, fault point, fault content, fault processing, time and other information completely, and can perform multi-condition query on these records to provide a complete system for managers Operation and maintenance information. ? Equipment management: The system carries out unified paperless management of all kinds of information of all monitored equipment to provide complete information for future equipment management and maintenance. ? Security management: The system can assign different operation and use rights to management and users, and group management of all management and users according to functions, to prevent system information leakage and interference by unauthorized personnel. ? Auxiliary analysis: The system can provide real-time curves and historical curves for the operation status of each device and system according to needs, which is convenient for managers to analyze the system operation status intuitively with the help of graphical means. ? Report output: The system is embedded with a powerful report system, which can not only satisfy basic and commonly used daily reports, weekly reports, monthly reports, but also support users to customize graphical (such as pie charts, histograms, line charts, etc.), personalized reports It can also import and export reports with general report software. ? Dynamic editing: The system is in the running state, allowing users to directly add, modify, and delete operations on each management station, subsystem, or device on the interface, and upload in real time to ensure that all modifications can take effect immediately, ensuring maximum assurance The data of the entire system is complete and efficient. ? Super compatibility: The system has the ability to be compatible with various brands and models of equipment and subsystems. ? Easy operation: Graphical full Chinese operation interface makes the user's learning and use extremely easy. V. Project overview, design ideas and basis The following plan is made after comprehensively considering the actual situation of the user and the investigation report of the project site. The design purpose of the design plan is to build the monitoring center of the user unit into a protective barrier with a relatively high level of advanced technology, digitization, scalability, and effectiveness. The design comprehensively inspected several popular digital monitoring architectures during the design, combined with the specific actual situation of the user unit, in line with the design concept of moderately advanced, first-class design and cost-effective priority.
