Description
Technical field
The present invention relates to surveillance, particularly relate to a kind of supervisory control system of accuracy self-adapting.
Background technology
Monitoring is the physical basis that every profession and trade key sector or important place carry out monitoring in real time, administrative department obtains valid data, image or acoustic information by it, the process of paroxysmal abnormality event is monitored timely and is remembered, in order to provide efficiently, in time commander and height, arrange police strength, settle a case.Developing rapidly and promoting along with current computer application, the whole world has started one powerful wave of digitalization, the various equipment digitalized primary goal having become security protection.The performance characteristics of digital monitoring alarm is: monitored picture shows in real time, video recording image quality single channel regulatory function, and every road video recording speed can be arranged respectively, quick-searching, multiple video recording mode set-up function, automated back-up, The Cloud Terrace/lens control function, Internet Transmission etc.
Supervisory control system is made up of shooting, transmission, control, display, record registration 5 major part.Video camera passes through coaxial video cable by transmission of video images to main control system, and vision signal is assigned to each monitor and video recording equipment by main control system again, synchronously can be entered into needing the voice signal of transmission in video tape recorder simultaneously.By main control system, operating personnel can send instruction, control and camera lens is carried out to the operation of focusing and zooming to the action of the upper and lower, left and right of The Cloud Terrace, and realize the switching between multichannel video camera and The Cloud Terrace by main control system.Utilize special video record processing pattern, the operations such as typing, playback, process can be carried out to image, make video recording effect reach best.
Supervisory control system has been widely used in social security protection and financial field.
As the basic guarantee of safe city, social security protection be a cross-region, inter-trade, across application comprehensive public security prevention and control concept, all need to monitor in a lot of scene and field, comprising: all kinds of government, Party and government offices; The key units such as the explosion-proof and hypertoxic chemical industry of finance, Wen Bo, gun-related; The keypoint parts such as the water, electricity, gas involved the interests of the state and the people, nuclear power station; Key traffic route, the important main line of communication, important guard's route; Public security bayonet at different levels, urban entrance and exit; Public complicated place, public security complex region, large-scale square, civilian block, residential quarters; The scene of large-scale activity; Various kinds of schools, kindergarten; Mobile personnel, motor vehicles, mobile object, ship, river course etc.
Safety-protection system Surveillance center of society is generally divided into Surveillance center of basic unit and command centre of office of city.Command centre of office of city, both as the administrative center of Surveillance center of subordinate multiple basic unit, is again the emergency cooperative command centre in whole city.To 2008 the end of the year whole nation about have 2,750,000 monitoring cameras for supervision of the cities warning system.
Financial institution is the main circulation place of society currency, the important step that national economy is run, and its business relates to a large amount of cashes, marketable securities and valuables etc., is thus the object that offender pays close attention to always.Since 16th century, first hand modern bank was born, theft with antiburglary, plunder and anti-robbery, swindle and instead swindle, corrupt and combat corruption always along with the development of banking.In addition it has that scale is various, critical facility is various, discrepancy personnel are complicated, management relates to the features such as field is wide, and therefore bank one is directly subordinate to the emphasis safety precaution unit of country.All kinds of criminal activity for bank is in recent years risen increasingly, and means of crime and mode be variation, violence, intellectuality gradually also, strengthens comprehensively and improve safety defense monitoring system having higher requirement to bank.Along with photoelectric technology, information science technology, Microcomputer Technology, photoelectric image detect, process and the fast development of recognition technology and the network communications technology, new and high technology is utilized to prevent, prevent, fight crime, in three large risk prevention instrumentses (i.e. precaution by persons, equipment and techniques), occupy leading position gradually, bank's safety monitoring technology is also from traditional analog to digitlization, networking, intelligent development.
Existing supervisory control system is more and more intelligent, and the photography pixel of camera is also more and more clear, and the effect of performance is increasing.But, also there are some defects in the existing system much carrying out monitoring for people: its pixel carrying out monitoring is all generally fixing, be generally the maximal accuracy of camera, when precision comparison of making a video recording is large time, although the features such as face can be photographed clearly, time but precision is large, data volume is large especially, no matter concerning transfer of data or data store, bear all very large, and when precision comparison of making a video recording is little time, although transfer of data is very fast, also data are facilitated to store, but the too fuzzy situation of being inconvenient to recognize of feature is often there will be when carrying out feature extraction.
Patent " a kind of adopt different monitoring precision to carry out monitoring method and terminal " (application number: 200810090183.5 applyings date: 2008-04-14) disclose a kind of adopt different monitoring precision to carry out monitoring method and terminal, the method comprises: user sends monitoring precision setting information to monitor terminal, comprising one or more time period and monitoring precision corresponding to each period; Monitor terminal, according to receiving described monitoring precision setting information, adopts corresponding monitoring precision to monitor control point within each time period of its instruction, and when meeting alert if to User Alarms.Above-mentioned terminal comprises camera, network function module, main control module.Adopt the method for this invention, user can be made to set the monitoring precision of control point according to the actual demand of oneself, making monitoring accuracy self-adapting in different monitoring situations, not only can reduce false alarm, also can making the more convenient user demand with meeting user of the use of monitor terminal.
Although this mode can adjust the precision of monitoring, but it needs user to its manual setting accuracy, then the passive precision according to setting slot setup is taken, automatically according to the adaptively selected suitable precision of the situation of monitoring site, can not can not solve transfer of data and data when taking for people and store the large problem of burden.
