To say what is the hottest in this year's Expo, it must be video cloud and artificial intelligence.
First-tier companies have demonstrated their video cloud solutions, and artificial intelligence has become an integral part of video surveillance. System vendors and smart analysts have demonstrated face recognition or related applications. This trend shows that the use of video clouds to build urban video surveillance has become the consensus of the industry.
However, the concept of the video cloud is very good, but the actual landing is very skinny. The only successful demonstration of successful cases is Huawei, and other vendors are at the show stage. The reason is that video cloud construction is a systematic project. Under the traction of the No. 996 Document of the State, video surveillance has been freed from the mode of decentralized construction and simple application of various departments, but has become a model of unified planning, intensive construction, and intelligent application. , is already a city-level system engineering. On the other hand, in addition to technological innovations, the video cloud also requires more comprehensive capabilities of vendors. Traditional vendors still have shortcomings due to lack of necessary IT capabilities such as cloud computing big data.
As a city-level system engineering, the top-level design becomes very important. It is necessary to design the construction scheme from the top perspective and the system perspective. It can be said that the level of the top-level design directly determines the construction and application of the public security video surveillance.
What is the top design
The concept of top-level design stems from top-down design in the field of system engineering, that is, from the problems to be solved, the top-down problem is gradually decomposed into a relatively independent sub-problem. Each sub-problem can be further decomposed until the problem is simple enough to be solved easily. Later, the concept has been widely used in military and sociological fields in Western countries, and has even become an important analytical method for the government to formulate national development strategies.
The top-level design is a method of using system theory. From a global point of view, overall planning is carried out for each task, or for each aspect, level, and elements of a certain project, so that effective resources can be concentrated and the objectives can be achieved quickly and efficiently. For video surveillance, it is necessary to co-ordinate the construction goals, business, data, and technology of video surveillance, and systematically solve the problems of blind construction, data islands, and waste of resources.
How do video clouds do top-level design
Combining the characteristics of the public security industry, the top-level design model of the video cloud should include seven elements: business, application, data, technology, standards, security and performance. Business, data, and application are the three core architectures. The business determines data and applications. Data and applications determine the choice of technology architecture. The technical architecture in turn supports continuous innovation of applications.
Business architecture
Through the business carding, establish a business lineage related to video surveillance, and clarify the business relationship, process and goals.
Data architecture
Organizing, classifying, and designing data according to the needs of the business to achieve efficient data governance is the foundation and core of video's value.
Application architecture
Based on the business architecture and data architecture, according to business needs, determine the application system classification;
Technology Architecture
Carry out the technical system of video surveillance construction, application and development, support data applications, and the continuous evolution of business development;
Security architecture
Implement the core basic framework of video surveillance security protection and defense measures to ensure full control;
Standard architecture
Follow the national standard or department standard, and realize the technical requirements for data sharing, information system interconnection, interoperability, and interoperability, and the general principles of related terms, symbols, codes, and methods;
Performance architecture
The framework guideline for the performance evaluation of the project construction will effectively evaluate the results of the system construction, output, processes, and technology, and ensure that it is available at all times.
Due to space constraints, this article will focus on how ICT-related data architectures and technology architectures can be used for top-level design.
Top-level design of data architecture
According to the requirements of Circular No. 996, the government must coordinate the construction of public security video surveillance systems to avoid duplication of investment, and allow video surveillance to achieve remarkable results in strengthening public security prevention, optimizing traffic travel, serving city management, and innovating social governance. Therefore, data fusion and sharing and breaking existing data islands will be the primary considerations. The entire system must stand at the level of the city, coordinate the construction of the city public safety video surveillance data lake, realize the massive convergence of various video resources, integrate the public security video, commissioned office video, social video, and share it with the cloud service. Related departments to meet the needs of all walks of life.
In depth applications, each line department can accurately process data according to their own needs to meet industry-specific innovations. For example, for the public security department, it is possible to perform structural analysis on video data, extract feature information of people, vehicles, and objects, combine large-scale data collisions, and track information of landing vehicles to meet the needs of multiple types of combined operations and flattening. Command and other needs ensure scientific decision-making, accurate early warning, and accurate strikes, and establish a three-dimensional combat system of "fighting prevention and control."
Technical architecture top-level design
Technical architecture should consider advancedness and openness. Based on the latest cloud computing, artificial intelligence, and big data technologies, it adopts an open system architecture that avoids the problems of system binding and vendor binding, and realizes hierarchical decoupling design of hardware and software, data, and applications to meet the business continuity. Evolution, development and innovation needs.
In terms of specific architecture, we must systematically present hierarchical designs from the perspective of sense, transmission, management, and use.
sense
Build a comprehensive city video surveillance perception system to create a three-dimensional multidimensional data collection;
pass
In accordance with the actual needs of social public security and government affairs, economy, and people's livelihood, a unified video network is designed to realize non-blocking and low-latency data transmission, and the video resources of various departments (public security, transportation, safety supervision,*, water conservancy, etc.) are unified. Network integration;
tube
Relying on cloud computing, artificial intelligence, and big data technology, it builds a cloud, a pool and a platform to realize the sharing of computing and storage resources, avoiding duplicate investment, and realizes a video lifecycle service platform in a cloud to satisfy video management. Analytic, big data analysis needs, realize the application of social governance, intelligent transportation, service people's livelihood, ecological construction and protection, and provide more and better services for the society and the people;
use
On the basis of the video lifecycle service platform, we will expand and deepen the application of video, build public security application centers, comprehensive application centers, and various commissions and offices, and Huimin applications. Each department will develop special applications as needed, and deepen video images in each line. The level of application of the industry, the value of the video;
Video cloud construction is a systematic project. The lack of effective top-level design will greatly reduce the effectiveness of the project and cause huge economic waste. With the deepening of video surveillance networking applications, top-level design will become more and more important. Creating an open, advanced and sustainable speech system for urban video cloud will maximize the value of video and serve public safety and various lines. All industries benefit people's livelihood.
