And management, help users control the operation of the device in real time, and conveniently maintain the video surveillance system.
At present, reports that are often monitored as “eyes†are reported in the newspapers, and it is extremely impractical to patrol large and rapidly growing video surveillance points with limited manpower, making video surveillance equipment the following in terms of operation and maintenance support services. Various problems: the delay of delay is serious, the event can't respond in time, and the limited manpower is difficult to support; the equipment mode is diverse, the maintenance mode is inefficient, and the maintenance service is quite difficult.
Second, the development trendThe operation and maintenance of the video surveillance system relies entirely on manual detection and processing. The monitoring is difficult, the fault handling is not timely, and the operation and maintenance workload is huge, which leads to an increase in the cost of operation and maintenance, which greatly reduces the use effect of the video surveillance system. Therefore, to improve the informationization level of the operation and maintenance of video surveillance systems, the construction of information-based video surveillance operation and maintenance management system will become the development trend of video surveillance industry.
The video monitoring system online monitoring and operation and maintenance system is an innovative product in the security field. It is a typical application of video analysis technology and the latest IT technology in the operation and maintenance of video surveillance systems. The system integrates state monitoring, fault alarm, fault analysis, operation and maintenance management, and can monitor and query the running status of equipment related to various video surveillance systems, such as cameras, video and audio codec devices, and service servers. Once the operation and maintenance system finds that the operation status of the video surveillance system is abnormal, it immediately sends a fault alarm to the operation and maintenance management center.
After receiving the equipment fault alarm, the operation and maintenance system management center automatically performs fault analysis and initially analyzes what caused the fault. At the same time, through the unified operation and maintenance service operation platform, the operation and maintenance system automatically discovers faults, manual warranty failures, routine maintenance and other work in a unified and standardized manner, and completes the whole process of fault handling, completing advanced and reasonable fault repair, The task dispatches the electronic flow system to respond faster and complete the fault repair task.
The online monitoring and operation and maintenance system of the video surveillance system can guarantee the normal operation of the video surveillance system in a comprehensive, systematic, standardized and timely manner, and it is difficult to maintain the video surveillance system, and the effective utilization rate is not high.
Third, system deploymentThe intelligent operation and maintenance host is deployed in each school to monitor the health status of the campus security system in real time. The operation and maintenance management platform is deployed in the management department to grasp the operation status of each school security system in real time.
The system exchanges data through the view, and lists the statistical indicators of each subdivision diagnosis item according to the requirements, and embeds the evaluation system into the operation and maintenance monitoring management module interface.
Fault alarm: After the video surveillance intelligent operation and maintenance system detects that the device in the video network has an abnormal state, the system will automatically generate an alarm record. You can select the alarm to be reported on the left side of the interface, and notify the user to check the fault in time by voice and text. The device and the sound and light device and corresponding display mode are linked according to the fault level. The fault information includes: the name of the device, the description of the cause of the fault, the time when the fault occurred, and the IP address of the video device.
Video diagnosis: using the most advanced computer intelligent vision technology in the world, common faults on camera equipment, such as equipment disconnection, screen color cast, lack of signal, abnormal clarity, abnormal brightness, etc.; and video related to video surveillance Equipment, network equipment operating status monitoring, link availability and quality monitoring of video signal transmission. The video intelligent monitoring point provides a complete intelligent fault analysis function, which facilitates convenient display and query of the entire network operation, and provides detailed fault information for the operation and maintenance management system.
The video fault is divided into 24 video quality faults such as video sharpness anomaly, video signal missing, brightness abnormality, video stripe interference, video snowflake interference, video color cast, PTZ failure, picture freeze, scene change and so on. The system uses the latest intelligent diagnostic analysis algorithm to simulate human visual response, video image feature modeling, and adaptive learning to detect video faults.
Device Diagnostics: Detects the status of the camera, such as connectivity status, disk status, recording status, security vulnerabilities, and comprehensive detection.
Status inspection: Detects the working status information of cameras and video coding equipment in the video surveillance system.
Round patrol diagnosis: The system can perform round-trip diagnosis on common image quality faults appearing in camera equipment, such as device connectivity, screen color cast, signal loss, sharpness fault, brightness fault, stripe interference, snowflake interference, scene change, screen freeze , PTZ failure, artificial occlusion failure; for the detected video image quality failure, provide detailed intelligent failure analysis function, provide detailed troubleshooting information for the operation and maintenance management system.
Statistical analysis: Users can conduct timely and detailed statistical analysis in a multi-angle and multi-condition manner. The system can also guide users to repair faulty equipment in time, and provide users with an assessment basis for operation and maintenance process and results.
Operation and maintenance management: system operation and maintenance management can realize operation and maintenance management of camera image failures, and can perform operation and maintenance confirmation, distribution, maintenance confirmation, failure processing and other processes according to the organization, time period, type, number and other conditions. Track the query function. The operation and maintenance management supports two forms of automatic fault detection and automatic repair. The alarm notification and manual inspection find fault repair for remote operation or distribution of work orders. The operation and operation records of each step of the system are recorded in detail.
