Campus Security Operation and Maintenance System Status and Application

In the past year of 2017, when you talk about hot topics, you may be most impressed by the Beijing Red, Yellow and Blue Kindergarten child abuse incident. In the course of investigating the incident by the public security organ, the video storage hard disk of the surveillance class concerned was retrieved and found to be damaged. For a time, the topic of "storage hard disk" caused many hot debates in IT and security circles. "Why is the monitoring system's hard disk always bad?" This article wants to talk about the reliability and availability of the campus monitoring system from the perspective of security operation and maintenance.

First, the status of campus security system operation and maintenance

In recent years, with the constant attention of various types of schools and education authorities at all levels, security products have been increasingly deployed in the education industry, and their applications have become more and more popular. From the construction of a safe campus for the purpose of protecting the safety of teachers and students, to the online patrol examination system for improving the efficiency of invigilation, and to the baby online system for the purpose of expanding the service content, security products are gradually extended to the school's safety precautions. Teaching, management and other aspects have played an important role. Of course, there are many problems in the application process:

(1) Light maintenance, lack of inspection mechanism for system equipment

In recent years, campus security applications have gained a lot of popularity. However, some local schools’ security system construction investment is still mainly in response to the assessment and inspection of higher-level departments, ignoring the operation and maintenance of security systems.

Most of the devices installed in most campus security systems are rarely used in daily system operations and may only be called temporarily in the event of an emergency. However, due to the lack of necessary equipment inspection mechanisms, many equipments have discovered that they have experienced failures when they are actually needed, often causing serious consequences. This kind of situation is more common in the operation process of many campus security systems. Therefore, maintaining the proper operation of each security device is a major issue in the current system operation and maintenance management.

(2) Defects in the technical capabilities of the system operation and maintenance managers

Security's cross-domain and multi-system features, as well as IT, digital development, technology constantly updated, and the extent of technological complexity continue to expand. Whether it is a campus system built over the years and constantly improving, or a one-time newly built project, often The integration of products from different manufacturers with multiple systems, brands, and models has the problems of inconsistencies and non-standards such as protocols, interfaces, and standards. This type of work is shifting from labor-intensive to knowledge-based. Good job operation and maintenance work requires that technical operation and maintenance personnel master multi-domain knowledge theory such as “computer, electronics, information, and communications” and collect professional experience of “project, technology, and R&D”. In one, it emphasizes the ability to quickly "analyze, locate, and solve" problems, and even to a certain degree requires the use of professional tools and software to complete the rapid diagnosis of the working status of the system, and campuses often do not have professional system maintenance personnel, even if they have operation and maintenance personnel. It is also difficult to meet the requirements of the technical operation and maintenance services. This is another important challenge in the current operation and maintenance management.

Second, the development of the maintenance system

The security industry has undergone decades of products, systems, and platforms. Simulation, digital, and intelligence have led to a leap-forward development in construction, maintenance, and service. The maintenance and protection system has also undergone great changes. The development has undergone roughly three stages so far. :

In the first stage, O&M, as a component of the monitoring and management platform, provides only the detection of the lens online or not, and is marked in the resource group. The application function at this stage is very simple.

In the second stage, with the development of technology and systems, O&M was then independently out of a specialized system, and it was matched with corresponding statistical analysis of data, more types of equipment, and simple work order services.

In the above two phases, the user expects to be able to understand and control the work of the construction and operation and maintenance units, but it is difficult to obtain the real information and even the real cause of the failure. The quantity, quality, and security of the external field equipment lack the necessary means of control. The increasing failure rate has become a common situation in security systems.

At present, the security operation and maintenance system is in the process of development and progress to the third stage. The characteristics of this stage are "smart" and "closed loop", which we call "wisdom maintenance management system". Compared with the past, the system is equipped with a more complete equipment state detection mechanism, combined with the CMDB and the complete life cycle management of equipment and systems, combined with a variety of terminal applications such as mobile terminals, and a variety of data collected for a unified analysis, with a view to Achieve better operation and maintenance results. With the development and change of the operation and maintenance system, the operation and maintenance management of campus security has also gone through this development process. At present, the campus security operation and maintenance business has been paid attention to more and more intelligent operation and maintenance management system has been applied in the education industry, allowing users to more efficiently achieve the operation and maintenance of the entire system in a short period of time.

Third, the application of campus security operation and maintenance management system

In view of the prevalence of heavy-duty construction in kindergartens and school monitoring systems in recent years, low online rates and soundness, difficulty in monitoring the system operation and maintenance of the kindergartens and schools under the Board of Education, and failure to discover faults and hidden problems, the education industry in the country is in urgent need. An intelligent operation and maintenance management system needs to be deployed in the District Education Committee and the Municipal Education Commission to implement 24-hour automatic intelligent diagnosis and detection of subordinate units' monitoring systems. Monitoring equipment (including cameras, hard disk recorders, hard disks, and alarms) for each subordinate kindergarten or school Probes, etc.) Real-time monitoring to ensure that all monitoring systems in the kindergarten or school are available in real time, video data is not lost, and the system does not lose control.

The intelligent operation and maintenance management system is a business application monitoring system and maintenance management system for the security IoT platform. Taking the ITMS intelligent operation and maintenance management system launched by Xeno Vision as an example, it is mainly used to carry out the equipment in the campus security system. Monitoring, abnormal discovery, fault location, problem tracking, business assessment, data mining, operation and maintenance services, and management optimization to facilitate automation, standardization, and intelligence in operations and maintenance, and help manage and interact with each other with assessment management, data mining, and decision support systems Promote and continue to optimize, and then reduce personnel costs, improve the availability of factors, strengthen the standardization of management, and improve the current high failure rate of equipment commonly used in campus security applications.

The system designs its functions around the core business processes of “discovering faults—diagnosing faults—disposing faults—data analysis and mining”, which are embodied in applications such as equipment status detection, intelligent diagnostic analysis, operation and maintenance business management, and data statistical analysis. detail.

First, the system can provide comprehensive intelligent fault detection capabilities. The detection targets include campus security monitoring equipment (cameras, DVRs/NVRs, video storage devices, alarm access devices, etc.), network equipment, IT equipment and systems, and equipment room power environment equipment. And so on, and with intelligent quality diagnostics, intelligent video diagnostics, intelligent network diagnostics and other comprehensive intelligent detection capabilities.

Second, the system has a high degree of intelligence. It can automatically detect problems such as loss of video images, abnormal screens, scene changes, video jitter, screen freezes, and screen blockages, diagnose faults, and prompt alarms; and can provide networks. Automatic topology analysis accurately locates the nodes where all kinds of faults reside.

Third, the system adopts advanced data mining technology and adopts intelligent analysis methods such as pattern recognition and feature recognition, neural network, and computer image processing. It adopts a multi-threaded and multi-process processing mechanism to intelligently adjust data detection and analysis strategies, and processing speed. Fast, low resource consumption, high data accuracy, and strong anti-interference ability.

Fourth, the system provides a multi-level management model, provides multi-dimensional maintenance and support measures, can support mobile APP failure alarm notification and work order tracking, supports customized operation and maintenance portals, and provides unified transportation for the Board of Education and subordinate kindergartens and schools. Dimension management provides a more convenient platform for use.

Fifth, based on intelligent pattern recognition and big data analysis technologies, the operation and maintenance support system can also perform structural analysis on large-scale data detected in real time. Machine learning and intelligent early warning of abnormal changes in image resources may occur. The problem, or the existence of a risk, or suspected subordinate units, so that post-mortem investigation into prevention in advance, become passive response to active control.

The system has an in-depth understanding of the application systems and equipment in the actual environment, as well as understanding and further understanding of the operation and maintenance business, effective integration to build a practical, applicable, easy to use, all-platform, universal operation and maintenance management system to achieve campus Security operations system needs for business monitoring such as status monitoring, fault detection and diagnosis, operation and maintenance management, disposal plan, work order processing, problem tracking, automatic analysis, data mining, and decision support. At the same time, through the construction of an intelligent automatic analysis expert system and an operation and maintenance management knowledge base, the automation level of the operation and maintenance management is improved, and the standardization, convenience, and high efficiency of the operation and maintenance management are further guaranteed. At present, the system has been successfully applied in a number of campus security projects across the country, ensuring the integrity of the software and hardware equipment of the security project system.
