Description
Technical field
The utility model is related to a kind of monitoring system, specifically a kind of smart city video monitoring system.
Background technology
Smart city is exactly with information and communication technology (ICT) means sensing, analysis, integrates each of city operations core system
Item key message, to be made to the various demands including the people's livelihood, environmental protection, public safety, urban service, industry and commerce activity
Intelligent response.Its essence is advanced information technology is utilized, the management of city intelligent formula and operation are realized, and then be the people in city
More good days is created, harmony, the Sustainable Growth in city are promoted.
Proposed on NPC and CPPCC within 2015 " internet+" concept make smart city industry build welcome it is preceding not
Some opportunities to develop.Input of the China on smart city is already more than 500,000,000,000 yuan, it is contemplated that future investments can rise to 1.1 ten thousand
Hundred million yuan, the construction of smart city will march toward high-speed development period.
Smart city is can be seen that from the centrally planned economics meeting in national policy and this year still to will continue to send out forward steadily
Exhibition promotes.The construction application present situation of smart city video monitoring, is mainly analyzed from the following aspects.
1. headend equipment --- data acquisition is single
Smart city headend equipment mainly uses high-definition network camera to carry out video acquisition at present, and most of video recordings are quiet
Silent data, have no audio.The author thinks, without audio data collecting, mainly there is two aspect reasons：
(1) outdoor audio collection effect is poor.In city, environmental noise is all very mixed and disorderly most of the time, collected audio
Background noise removal can not be carried out, and can not distinguish and retain useful audio data.
(2) back-end platform is inadequate to the digging utilization of audio data, causes collected audio data substantially useless, and wave
Take memory space.
Most of front-end camera can access various warning devices, but most of shallow-layers that belong to are integrated, and deep layer is not formed
Depth on secondary especially application is integrated.
2. network transmission --- pressure mountain is big
The fiber optic network that smart city is provided using operator mostly at present carries out data transmission, the valence for fiber optic network of skimming
Lattice and quality, in terms of the degree of dependence from current video camera for network, once fiber failure, at least results in a front end and temporarily loses
Effect., in accident, catastrophic event or artificial destruction, the city decision-making management person for being badly in need of head end video comes for this
Say it is very fatal.
With the raising of resolution of video camera, the video data volume increases, and is growing on and on for the pressure of network.Undeniably
Network transfer speeds are also improving, and H.265 H.264 video camera coding techniques also from being upgraded to, network technology and video compress skill
The development of art can cope with 4,000,000 or 6,000,000 pixel camera machines, but can not necessarily cope with 8,000,000 pixels even 1200
The video data transmission of ten thousand pixels.
A large amount of video data will also result in prodigious data exchange pressure for each interchanger of network node.To carry
High data transmission rate must upgrade whole network equipment, thus can raise the construction cost of entire smart city.Even if network
Transmission technology, Data Interchange Technology, network technology, video camera coding techniques all upgrade, and can meet the requirement of data transmission,
But from the point of view of the data stability of entire smart city and safety, reduction seems very heavy for the dependence of transmission network
It wants.
3. platform and data --- it is inefficient, without profit
The safety monitoring platform of most of smart cities, major function, which is still, to be made as video preview with playing back videos
With.
In terms of the video data of magnanimity, can only say it is " mass data ", and really " big data " can not mention in the same breath,
Big data excavation upper " digging " obtains deep not enough.In face of the video data of smart city magnanimity, user is many times needed voluntarily
It is screened, for the video data of magnanimity, difficulty is very big for this.
With the continuous development of human society, future city will carry more and more populations.Currently, China is in city
The period of town accelerated development, some areas "urban disease" problem are increasingly serious.To solve urban development problem, realize that city can
Sustainable development builds smart city video monitoring system and has become world today's urban development an irreversible historical trend.
