Accompanying drawing explanation
In order to make the present invention be convenient to understand, specific embodiments of the invention are described now by reference to the accompanying drawings, wherein:
Fig. 1 is the system architecture schematic diagram of the present invention's one specific embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, a kind of expressway operation environment evaluation system, comprise road conditions telemetry system 1, environmental information processing evaluation system 2 and the large ingredient of communication commanding system 3 three, wherein road conditions telemetry system is comprised of telemetering device 101, data transmission set 102 and reception data terminal 103 3 parts; Environmental information is processed evaluation system and is comprised initial environment database 201 and real time environment sampling database 202; Communication commanding system 3 comprises Dispatch and Command Center 31 and motor vehicle terminal 32; Signal projector and receiver by each other between above-mentioned each system and each module thereof carry out signal transmission.
101 pairs of express highway sections of telemetering device are monitored, and obtain continuously motor vehicles the place ahead traffic information that travels;
Data transmission set 102 converts tested parameter to electric signal by transmitting terminal to be launched, and by receiving end, is received and is recovered original signal through detuner;
Receive data terminal 103 for record, processing and show information that remote measurement obtains;
Environmental information is processed evaluation system 2 for comparing initial environment database 201 with real time environment sampling database 202 and the result of both comparative analysiss being sent to Dispatch and Command Center 301 with instruction, wherein initial environment database 201 is, before operation, working line is carried out once to the information data of environment remote measurement gained completely, the environmental data that real time environment sampling database 202 obtains in real time for receiving data terminal 103;
Dispatch and Command Center 31 is for receiving the instruction of processing evaluation system 2 from environmental information, according to circumstances by transmission security instruction between communication mode and motor vehicle terminal 32 or warning instruction.
Wherein telemetering device is some probe 101A, 101B, the 101C etc. that are arranged at road some telemetry stations place along the line, the position of each telemetry station adopts the three-dimensional coordinate form of longitude, latitude, height above sea level, distance between adjacent telemetry station is determined by landform, straight line path segment distance strengthens, and detour ground segment distance reduces; For by massif, the special location such as culvert mouth, river, on the basis of original telemetry station, add remote sensing equipment, carry out omnibearing detection.
The telemetering device that is arranged on a certain telemetry station position transmits instruction by certain hour interval to being arranged on the telemetering device that closes on next stage telemetry station, by transmitting step by step, realizes the real-time information collection work of road conditions completely.
Above expressway operation environment evaluation system is worked in the following manner: before operation, information data all fronts environment remote measurement being obtained on all telemetry stations of take is Foundation initial environment database 201, this database can carry out constantly perfect, supplement and revise.In vehicle operating process, by closely remote measurement, within No. 1 o'clock, to the remote measurement of No. 2 points, No. 2 o'clock to the remote measurement of No. 3 points ... and the final real time environment database 202 that obtains instant sampling, grab sampling of continuity step by step successively.Utilize the powerful processing power of computing machine, the information of the information in initial environment database 201 and 202 collections of real time environment database is compared, analyzed and reach a conclusion.For example, at the initial environment database Bridge of setting up, be stable, if there is bridge collapse accident, there is extensive displacement in bridge, great changes have taken place for the real time environment data that now instant sampling obtains, and along with bridge translational speed is accelerated, data message changes aggravation, two kinds of information exchanges are crossed computing machine and are calculated, analyze, process the conclusion that will draw road ahead environmental change, and this conclusion is sent to Dispatch and Command Center 31.Dispatch and Command Center 31 receives and comes from the conclusion of environmental information processing evaluation system 2 and come from after the vehicle position information of motor vehicle locating device 31, according to actual conditions, by communication mode, to motor vehicle terminal 32, send the warning instruction of section, the place ahead bridge collapses and be presented on the information presentation device 322 of motor vehicle, thereby realizing the evaluation of expressway operation environment.In addition, Dispatch and Command Center 31 receives from can to coming from, the locating information of different motor vehicles contrasts or computational analysis draws motor vehicle spacing after the locating information of different motor vehicles, can compare with default safe distance and send forecast, the generation of Accident prevention.Generally under normal circumstances, the minimum following distance that keeps certain default safe distance can adopt highway to require between motor vehicle, in particular cases this safe distance setting can be performed as follows: (1) is if two cars is parallel and during inverted running, default safe distance can dwindle; (2) if when two cars intersects dislocation inverted running, default safe distance should strengthen according to vehicle speed condition; (3) if default safe distance must surpass and enough makes motor vehicle intersect the distance length of dislocation during the relative inverted running of two cars.
Communication between the principle of work of above-mentioned each system module and each module all belongs to prior art, and above combination specific embodiments of the invention are described in detail, but are not limitation of the present invention.Every foundation technical spirit of the present invention, to any simple modification made for any of the above embodiments, all still belongs to the scope of technical solution of the present invention.
