Solution Introduction
The present situation and development trend of ping an city
In peace around the city in the process of project construction, has completed a large area of peace city front deployment, the back-end system application has been gradually formed complete system,
the public security organs at all levels shall, in accordance with the "built for use, use for war" principle, has focus gradually changed from the construction of infrastructure to practical application, at the
same time to maintain the operation of the system as a whole and daily management puts forward new requirements.
In hd, network, intelligence in the three major technology trends, intelligent technology is paid attention to all day, from the front-end acquisition perception, intelligent transport to the actual combat application
platform, smart technology widespread application, will promote the continuous development of "safe city". To summarize the current trends and problems in ping an city, there are several aspects:
Shift from high definition to smarter
In the construction of ping an city, image clarity has been a key indicator of the system from the time of the simulation to the IP age. The simulation of sd front-end equipment in the construction of safe city has
been largely replaced by hd coaxial, network hd gradually,
network includes 720 p, 1080 p hd resolution, 4 k, etc., the back-end storage devices were also NVR, IP - SAN professional digital storage device such as a replacement. Image resolution, the objective of providing
favorable conditions for the intelligent analysis, at the same time with intelligent algorithm in the application and research in the field of continuous improvement and breakthrough, intelligent analysis gradually from
a single point of small scale experimental use to large scale project application.
Through continuous market application and practice, intelligent technology has gradually developed into various areas of urban security.
(1) the typical application of the intelligent transportation industry
The intelligent transportation industry starts early, and the corresponding algorithm is more mature. With the continuous development of the upstream chip manufacturers, part of intelligent analysis of the business
was transferred from the back-end to the front-end, from simple plate recognition and illegal capture to excessive traffic information perception level.
(2) the typical application of social security
With the mature of the algorithm and the improving of the front-end equipment performance, the intrusion detection front-end equipment, audio detection, intelligent functions such as face detection and left test and
the back-end storage devices such as NVR intelligent analysis function has become increasingly mature and perfect, has been applied in all kinds of security monitoring sites in the city.
(3) the use of image detection techniques
Urban construction has become increasingly perfect peace to image video enrichment, video leads to management, video search etc of intelligent technology and application have been widely used in public security
organs investigation case, provided strong support for all kinds of cases to solve.
(4) the management of equipment operations is intelligent
Huge amounts of equipment access inevitably brings the difficulty of the equipment operational management ascension, intelligent operations including equipment inspection, equipment quality diagnosis, and other
comprehensive technology, has brought great convenience for operational work.
Intelligent technology continues to develop in the applications of the front and rear devices
Under the background of the current intelligent application in full development, the application of intelligent bearing: the front-end and back-end equipment in the development of intelligent applications is not the same.
Backend intelligence analysis
In the early days, intelligent analysis function is the center of analysis the way to do this, the server access through the analysis of the intelligent video data from the front camera, separate the static background and
dynamic moving targets in video streams, according to the different rules to extract the target of the preset information.
Advantage: backend intelligence is greatly enhanced by using server centralized processing mode, capable of running multiple function algorithms simultaneously and compatibility.
Cons: the latter is relatively large when it comes to server mode, and the backend storage management and transmission bandwidth are more stressful.
Frontal intelligence analysis
With the improving of the front camera hardware specifications and performance, before the back-end intelligence analysis on the server can also be realized in the front part of the function, as well as related alarm
equipment, such as the horn, lights, SMS, E-mail, SMS, etc., for the moment, the front way solves the back-end analysis the problems of storage management pressure and transmission bandwidth.
Advantages: real time relative back-end analysis has a large advantage, the system construction cost is low, reduces the failure risk.
Disadvantages: high performance for front-end device and low compatibility.
To sum up, the current under the background of intelligent development, front-end and back-end analysis still exist mode, its function point will be some overlap, the front-end analysis still cannot completely replace
the back-end analysis, before and after the future intelligent development of division of labor will gradually clear, end products and function orientation will become clear.
The application of intelligent technology is constantly in line with the actual demand of the business
The current intelligent technology is more and more widely applied in the safe city system, real-time data analysis from the front to the back end of actual combat application of intelligent technology has all business
are inseparable with the safe city system. But in practice, there is still a gap between the application of intelligent technology and the actual business demand.
In the future, with the improving of the product technology and algorithm, and enrich the products, the current problems of practical application in intelligent will gradually reduce until solved, at the same time intelligent
applications will deep in fusion with "safe city" in the business.
