The Design And Implementation Of Wireless Video Transmission System In Public Security Incident Scene For XX City

Now,the present stage of our country is in the important period of socialisteconomic construction.The social security is very complicated,and there are variouskinds of emergencies and events.It is a challenges of public security for us.We mustimprove the public security work,and raise the content of science and technology.This isa development tendency and direction of our public security work.Although,our videosurveillance network has begun to grow up every year,but,the police will depend onvideo upload more and more.It’s very important to decision of the commander.There aremany places without monitoring system,or unable to set up monitoring system.So thekey issue is to use a system the scene image back to the command center.Now,there are more and more advanced means of science and technology,and thereis a variety of wireless video transmission technology.These techniques can achievevisual range and real-time video wireless transmission.we invest and research the videomonitoring system of many cities,and establish the city public security incident scenewireless video transmission system of my city,combined with the advantage of oneselfand actual situation.The system covers a large area, covering most areas of the city,andit can achieve dense buildings area, as well as complicated terrain area of wireless videotransmission.there have fast response,flexible and cheap.It is an important supplementto the fixed network video surveillance.We build the public security incident scene wireless video transmission system,andthere are many issuese,for example,Multichannel wireless image transmissionBidirectional-multi-point speech communication,Data interaction,a number of mobilestation,application of complex and complex application environment.We build thenetworking within scope of broadband mobile multimedia communication system.andthen we finish the public security incident scene wireless video transmission system.wewill supply the real time video of the control area or the incident scene.The system havemultiple base station-mobile station network,full duplex duplex,time division multipleaccess.So,our public security incident scene wireless video transmission system canachieve multiple departments, a unified scheduling, and has two-way multimedia communication function, thereby achieving a between base station and mobile stationtwo-way broadband communications demand.This system can not only in dealing withemergencies when in use, but also can be applied to routine police work.This paper studies the security incident scene wireless video transmission system iscomposed of HqMobile Net series of broadband mobile multimedia communicationdevices, it can achieve two-way voice and data communication; has a flexiblenetworking mode, as well as the powerful features. The system also has solved thetransmission environment, complex, business model range, variable bandwidthrequirements and other problems; and at low cost, low complexity conditions guaranteea high degree of confidentiality and security. And made the city public security incidentscene wireless video transmission system after the completion of the futuredevelopment planning.
