As shown in Figure 1, in order to the monitoring urban transportation realizing Remote Dynamic is on-the-spot, more efficient, comprehensive feedback traffic scene information, and hommization by site traffic condition feedback to concern crowd, the urban transportation remote dynamic monitoring system of institute's framework is formed primarily of following a few part: according to the carrier loader 7 of certain tracks motion, be fixed on the data acquisition module 1 road scene being carried out to data acquisition on carrier loader 7, data are carried out to the wireless data transceiving base station 2 of wireless receiving and dispatching, to the server 3 of data analysis, mobile terminal 4 and the APP software 5 be arranged on mobile terminal 4 with transmitting/receiving wireless data function are formed.Wherein, carrier loader 7 is arranged on track 6, relies on motor to drive or cable traction and along rail moving (certainly, belt, Timing Belt, chain, wire rope and so on also can realize traction).Or carrier loader 7 is a unmanned aerial vehicle (as shown in Figure 4) inherently, unmanned aerial vehicle is according to the route flight of specifying, that is to say when carrier loader 7 is a unmanned aerial vehicle, its track 6 is not just traditional entity track, but a kind of electronic chart, fly in the path that unmanned aerial vehicle is planned according to electronic chart.Connected by one or more modes in electricity, optical, electrical magnetic between data acquisition module 1, transceiver base station 2, server 3, mobile terminal 4, that is: so-called electricity comprises forceful electric power and weakness, and forceful electric power refers to the power electric providing power, and weakness is control signal; So-called light comprises Optical Fiber Transmission, photoelectric sensing; So-called magnetic, refers to electromagnetic signal, the electromagnetic signal that such as wireless router sends.Very common, often comprise above-mentioned three kinds of connections in a network system.
As shown in Figure 1, within the system, data acquisition module 1 is collection site data movably, data are sent to server 3 by wireless data transceiving base station 2, server 3 pairs of data analysis also send instruction to carrier loader 7 and the equipment that delivers thereof, mobile terminal 4 is provided with APP software 5, the data sent by APP software 5 invoking server 3.Generally: the instruction that data acquisition module 1 sends according to field condition and server 3, move with clapping to traffic scene, and by wireless transmission method, data are returned to server 3, server 3 is analyzed information such as the video fed back or pictures, if need to allow it move according to the route of command request with regard to sending instructions to carrier loader 7, to the equipment that carrier loader 7 delivers (such as: video camera, warning lamp, illuminating lamp, even robbing-resistant facilities) send instruction, allow it do action according to command request.Traffic is also issued by wireless transmission method on the mobile phone of stifled driver on the way by server 3 simultaneously, driver opens the special APP software of mobile phone by installing, view field condition (such as: the degree of car to car impact, the condition of the injury of the wounded, also need how long could dredge traffic, whether have the information such as explosion danger), and do next step plan according to obtained information and (mood of driver's impatience can be alleviated, can be stopped working mobile phone of playing, can get off and appreciate roadside beauty, also can overlook the night scene under viaduct).
As typical apply, described data acquisition module 1 is the multimedia image system that one or more video camera is formed.One or multiple stage (multiple angle shot) video camera are arranged on carrier loader 7 or unmanned aerial vehicle, are to traffic scene the simplest surveillance style, because video and photo can reflect field conditions.
Certainly, described wireless data transceiving base station 2 its essence is a wireless signal receive-transmit system, or a network platform.Further, can be also wireless signal transmitter, common are: wireless router, bluetooth etc.
Described wireless network transmissions, its mode mainly includes but not limited to: 1) GPS, 2) Big Dipper, 3) bluetooth, 4) wifi, 5) GPRS, 6) 3G, 7) 4G, 8) 5G.Wherein modal no more than wifi, bluetooth, mobile network signals (China Mobile, CHINAUNICOM, China Netcom).
Common mobile terminal is such as: smart mobile phone, panel computer, the mobile internet device that on these Dou Shi roads, driver is the most frequently used.Also be indispensable electronic equipment.So when traffic congestion, particularly highway, overpass, culvert section, tunnel, on car, pedestrian cannot select other modes to go to evade congested link, can only wait in car.Now playing mobile phone is current modal a kind of mode of killing time, if recognize reason and the field conditions of congestion ahead by mobile phone, will greatly alleviate the mood of the crowd that is blocked.
As shown in right side carrier loader 7 arrangement in Fig. 3, the track 6 of described carrier loader 7 is laid along road bearing of trend, and described carrier loader 7 is arranged on track 6 successively, and its quantity is not less than 1.Certainly, if the quantity of carrier loader is 1, so its region monitored may be shorter, such as: the bridge that span is shorter.In the side deployment rails of bridge, the monitoring that a carrier loader can complete whole bridge floor section is only set therebetween.Because to drive against traffic regulations T.T. that the car of (making a phone call during such as driver driving) passes by this section only clock in a measure with bat one.
When monitoring section and being longer (such as Huanghe River Highway Bridge), want intactly to monitor this section, a carrier loader is incomplete, needs multiple stage carrier loader to run simultaneously.Such as, a vehicles peccancy (seizing the ruffian institute steering vehicle of hostage on both sides by the arms), travels on Huanghe River Highway Bridge, blocks or low running speed before and after bridge, even rescue track is also blocked by the truck of tumbling.So vehicle supervision department just can send instruction by server 3 to carrier loader 7, calls wherein two or three carrier loaders 7 carry out multiple angle with clapping, until it leaves bridge from multiple angle to the vehicle that ruffian drives.And other traffics complete monitoring by remaining carrier loader 7, supervisory system is made to keep complete.
A kind of situation: as left side carrier loader 7 arrangement in Fig. 3, the track 6 of described carrier loader 7 is laid along road bearing of trend, and described carrier loader 7 is sequentially arranged on track 6, and its quantity is not less than 1; The terminal of last carrier loader 7 range of operation is adjacent with the starting point of rear carrier loader 7 range of operation.Generally: each carrier loader 7 moves in the distance of regulation, can not cross the border, and also has in the scope that it runs and only have a carrier loader 7, front and back are connected the complete route of formation one section.In this case, if carry out with clapping to a chassis, can realize as follows: A carrier loader starts with clapping, terminate to during its end of run, B carrier loader is then followed and is clapped, the like, until terminate with clapping, server 3 splices the video that each dolly is taken, even if complete information.
Certainly, with clapping just a kind of common traffic monitoring mode.
Commonly: when traffic congestion blocks, carrier loader 7 carries video camera and moves along track 6, take one section of complete video, this video is returned to server 3, (in order to save flow after server 3 processes, compressible video) issue mobile terminal 4, driver opens the APP software on mobile phone, see this section of video, many distances are plugged before recognizing, irritable degree can reduce a lot (generally, in the complete unclear situation of traffic congestion, the phychology of people is the most worried) at heart.Also or, be about to the pedestrian entering this section, after seeing this information, just have selected and detour, avoid blocking add stifled.
Typically: when occurring without traffic hazard, or traffic is non-blocks up the period (period in morning), and each carrier loader 7 is stopped, its photographs equipment can carry out static state shooting, and information return service device 3, this namely current traffic monitoring mode.
The equipment that described carrier loader 7 delivers includes but not limited to: video camera, camera, warning lamp, megaphone, illuminating lamp, sound-track engraving apparatus.Under normal circumstances, wisdom traffic system not only only has monitoring, also should have and carry out dredging and accident treatment function.Be exemplified below:
Staff's (being generally the staff of vehicle supervision department) before server 3, see in front of the display in picture and have driving limit, people limit to make a phone call, the speed of a motor vehicle slowly, causes the speed of a motor vehicle on whole grade separation to slow down.Immediately call and from its nearest carrier loader 7, it is carried out with clapping, and by the megaphone on it, this driver is propagandaed directed to communicate, remind its closing hand phone that loses no time, normal driving, otherwise fine of taking pictures.Like this, the source of falling to cause traffic congestion is just solved very easily.
Commonly: in tunnel, two cars knock into the back, slight scraping, and both sides driver cannot reach fast processing suggestion, even cause and block, (even if Emergency Vehicle Lane is also blocked by other two vehicles knocked into the back), both sides wait for that traffic police and insurance company come to process, and the traffic that this situation can have a strong impact in tunnel normally runs.Now, data acquisition module 1 collects traffic accident information, " accident review " can be issued server 3, after the staff of 3 sees prompting before server, can call the shooting evidence obtaining that all angles are carried out in nearest carrier loader 7 pairs of scenes of the accident.Confirmation is complete, after being enough to the evidence material as accident settlement and settlement of insurance claim accordingly, to field accident, car owner propagandas directed to communicate, point out it: accident evidence-gathering is complete, field data is preserved intact, please sail out of scene fast, arrive vehicle supervision department afterwards and carry out accident treatment or settlement of insurance claim.So just substantially increase the treatment effeciency of fender-bender, will greatly alleviate traffic congestion pressure.
Easily, the track 6 of described carrier loader 7 is fixed on the guardrail of overpass both sides, or is fixed on the wall of both sides, tunnel.Thus, described urban transportation remote dynamic monitoring system is very suitable for monitoring viaduct, the traffic of tunnel culvert.
If described carrier loader 7 is unmanned aerial vehicles, this will be more intelligent, and its scope of application is more wide, not only be used for monitoring and controlling traffic situation, and can call as safety-protection system.When carrier loader 7 is unmanned aerial vehicles, its track 6 is exactly a kind of electronic chart.This electronic chart can be the flight path preset, and the instruction that also can send according to server 3 is planned voluntarily.Certainly, electronic chart can only be stored in electronic storage device.
