Abstract
The present invention is one kind of over-the-horizon and curved observing system for railway train. The present invention can provide the engine driver with the observation capacity beyond the visual range to ensure the safety of the train.
Description
Affiliated technical field
The present invention is a kind of over the horizon and the curve observation and monitored control system of guarantee driving safety when being used for railway (comprising subway and city rail traffic route) train operation.Its radical function and task are to provide over the horizon observing capacity outside the maximum safe stopping distance of the observing capacity that (comprises the non-visual range under all abominable situations such as bend, tunnel, night, rain, snow, greasy weather gas) outside the visual range of circuit the place ahead, particularly train for train driver.Thereby guarantee that train can in time slow down and braking brake before meeting with danger, train is stopped at outside the hazardous location, at utmost ensure the safe in operation of train.
Simultaneously, native system can also be the control center and the station of railway, and the real-time video monitoring function to circuit and train in service is provided.And other corresponding Video service function.
The invention belongs to railway (comprising subway and urban track traffic) safety method and areas of information technology.
Background technology
In existing railway security technical system, the driving safety of train is to be ensured by the visual observation of chaufeur and emergency reaction ability.
The modern railways Developing Trend in Technology is: the speed of passenger train is more and more higher; The load carrying ability of goods train is increasing.Along with the raising of railroad train running velocity and the increase of traction load carrying ability, particularly the speed of Modern High-Speed train has per hour reached the rank of several hundred kilometers, and goods train reaches the load-carrying scale more than ten thousand tons.Under so high-speed and heavy, the inertia kinetic energy of train is very big, and the safety arrestment required separation distance is very long.And the visual observation distance of chaufeur and emergency reaction ability are a kind of Human Physiology abilities, can not pass through the corresponding raising of technological means, when jeopardizing the danger factor of train safe on the circuit, it is very short that such overlength braking distance is left the emergency reaction disposal time of chaufeur for, usually exceeded outside the physical endurance capability of reaction of chaufeur, this has just buried great hidden danger for accident final.
When train at night and rain, snow, when foggy weather travels because sight line is subjected to more obstruction, it is shorter that the time is disposed in the reaction of leaving chaufeur for, causes accident probability further to rise.
At mountain railway, because light can only rectilinear propagation, the visual sighting distance of chaufeur is subjected to great limitation especially, and short sight distance constitutes the major safety risks of mountain railway, and this also is one of major obstacle factor of improving of restriction mountain railway speed.
Along with the lifting of railroad train running velocity, these factors cause the driving safety of train to ensure that difficulty significantly increases.Because railroad train is the vehicle of big carrying capacity, in case have an accident, personal casualty and property damage are very heavy.Therefore, safety control is major tasks of railway interests, also is one of main contents of railway technology tackling key problem.
Because the danger factor of railway accident such as flood, mud-rock flow, driving rain, snow, mist, landslide, pedestrian and rule-breaking vehicle enter railway etc. much from outside the railway, have sudden with can not expection property feature, in existing railway security security system, also there is not the actv. way to prevent.The inner accident factor of the railway system can only be accomplished to reduce as far as possible by railway interests.For the outer accident factor of railway, can only adopt the artificial line patrol to check strick precaution at present, manually report to the police when finding accident factor or block mode such as train.This obviously is relatively backward mode.Usually can't avoid the generation of grave accident.
The invention technology contents
3,1 summaries
The present invention is a kind of by intensive layout camera head on railway line, circuit whole process is carried out the seamless video of segmentation makes a video recording continuously, then by wired-wireless high-speed communication device, the real-time video image frame of any section on the circuit all is transferred to the indoor video receiver of train driving, be presented on the read-out, observe the novel monitoring and the communication technology system of any position situation outside the circuit visual range of the place ahead for chaufeur in advance.
3.2, know-why
System of the present invention is that the video monitoring technology is wired with high speed---wireless data communication technology (being common appellation " 3G " mobile communication technology) combines, and is applied to specialization (network) technology in railway security field.Its know-why is based on the function that utilization " 3G " mobile communication technology can carry out at a high speed and Large Volume Data transmits, realize the real-time Transmission of circuit all videos realtime graphic signal between circuit and train, by providing these circuit real time video image pictures to observe in advance, reach the target that ensures train operating safety for chaufeur.
Here alleged over the horizon observation and curve observation are meant that chaufeur can observe the up-to-date video pictures of any position, the place ahead on the vehicle line by system of the present invention.The picture of the route curve position that comprises outside the visual sighting distance and can not directly observe.
Shown the place ahead circuit image picture, according to the observation needs, can turn over the circuit picture that screen shows train the place ahead setpoint distance continuously automatically by default, also can be by the picture (as the picture in the station, the place ahead) of the chaufeur position that manually selected the place ahead circuit needs are observed according to observing needs.For example, the up-to-date video image that when train was about to set out in the origin station, chaufeur can have access to any position, circuit the place ahead, comprise destination stop is drawn and is observed to read-out.
Because camera makes a video recording to circuit in continuous shooting mode, and is transferred in the receiver, the above-mentioned functions of system of the present invention makes any position on the circuit whole process concerning chaufeur, all becomes transparent appreciiable.He can observe the latest image picture of any position on the circuit by having access to the mode of camera numbering.From visual theory, but just be equivalent to the observed range that system of the present invention has extended driver's eyes arbitrarily.For providing curve, he looks the observing function of thing simultaneously.
Here alleged display frame automatic setting is meant that with manually selected system of the present invention can provide two kinds of functional modes simultaneously for the leading observation of chaufeur; A kind of is the spacing auto-set mode, a kind of is selected as required pattern, the spacing automatic setting is meant the circuit picture that shows the place ahead setpoint distance for chaufeur all the time, the maximum stopping distance of the limit of for example establishing train is 2000m, the physiological reaction delay distance that chaufeur carries out brake snub is 500m, the response delay distance of train braking system is 500m also, the shortest visual range of chaufeur is that 10m (refers to the most abominable observing environment, as environment such as night, storm, heavy snow, thick fog, curved tunnels), then can set range of a signal and be always locomotive the place ahead 3000m.In the train traveling process,, will be presented on the read-out for chaufeur observation to turn over the form of screen automatically continuously at the circuit image picture of this distance of locomotive front.Like this in train is advanced, chaufeur just can observe the outer line conditions of train the place ahead 3000m distance all the time in advance, when on the circuit any danger factor being arranged, chaufeur just can observe outside 3000m in advance, implements deceleration, brake operating thereby reserve the abundant reaction disposal time for chaufeur.
The crossover distance that automatic ranging shows can be by speed, load carrying ability, the line slope of chaufeur according to self train, and factors such as turning radius are set according to the relevant art standard of drag, shows that control then can be responsible for by giving the locomotive miles counter.The reference signal of the camera number that control shows (the circuit image picture that just shows this camera picked-up) promptly is the leading range of a signal number that the travelled distance number of miles counter adds setting, and its formula is
Q＝X?m+(3000m)
Here Q is the number of camera, represents the place on line (just being presented at the place on line on the read-out) of its monitoring and the distance of origin station, and X represents the distance (the regulation origin station is X=0) that train has crossed.Because the setting of camera is provided with at interval by certain distance, miles counter also is provided with the output of continuous two display control signals with same spacing, for example camera is by being provided with every 100m, then miles counter just be set to whenever train driving cross 100m apart from the time, just send 1 demonstration and pass and change signal, the image frame on the read-out is transformed to the circuit image picture of next camera.Recursion according to this.
Selected as required pattern then is that chaufeur is according to the observation needs, the corresponding camera number of input on keyboard (being analogous to the input telephone number), can directly have access to corresponding circuit picture and observe that (this has access to pattern, with to have access to corresponding stock trend graph by inputting equity stock code in stock market's transaction similar to the read-out.Principle of work is also identical).For example when train will cross certain station, he can have access to the image frame of the vehicle parking situation on other circuit, track switch route, platform situation, signal lamp etc. in the station in advance and observe.Avoid signal error to cause car accident.
By adopting many view displays, above-mentioned two kinds of Presentation Functions can be realized synchronously, for chaufeur observation.
Here alleged video camera has comprised the infrared photography function that can descend to make a video recording at night and rain, snow, mist inclement weather
Here the seamless shooting of the omnidistance segmentation of alleged circuit is meant a circuit by N omnidistance covering of basic camera, and wherein No. 0 camera represented starting point, and the N camera is represented terminal point.Each camera is responsible for length is made a video recording for the length of line interval of " N/one ".Between two adjacent cameras, there is certain coincidence amount the circuit video image picture connection place that the quilt that is covered is made a video recording, like this, the monitor of chaufeur and station and control center, press the numbering numerical order observation of camera from video image picture, no matter be the automatic ranging display format, or manually selected display format, the whole piece circuit is continuously observable.There is not video breakpoint blind area.
For the station, also on each the bar branched line in the Ying Zaizhan and track switch place arranges corresponding auxiliary camera.Have access to the vehicle parking situation on the circuit in the station, the place ahead that observes in advance for chaufeur, and this train is by the route track switch of circuit, the situations such as demonstration of signal lamp.

7, train driving is reached terminal, the last destination stop picture that shows No. 10000 camera automatically of read-out.The invention system is that the over the horizon and the curve observation service of this time train finishes.
The advantage of invention technology
The basic important meaning of the main task of native system and function is in the unprecedented lifting of railway security supportability.The advantage of the technology of the present invention is the safety in operation of raising railroad train that can be breakthrough.The incidence of reduction accident significantly, particularly great, Extra Serious Accident.The railway accident that the circuit danger factor are caused is reduced to the level of (approaching) zero
Because system of the present invention can supply observation for train driver provides the realtime graphic of the place ahead circuit outside the visual sighting distance, and the curve observing function outside the direct-view sighting distance also is provided simultaneously.The situation of circuit whole process all is transparent appreciiable concerning chaufeur, but is equivalent to prolong arbitrarily the observed range of chaufeur.When there is any danger in the place ahead circuit, chaufeur all can observe outside the Chang'an full application of brake braking distance of train in advance, just can take safety measures such as brake snub brake by easy stages, train is rested on outside the safety distance with dangerous point, guarantee that train does not contact danger.Thereby guaranteed the safe operation of train under any circuit dangerous situation.
Adopt after the system of the present invention, the restriction that the safe in operation of train will no longer be subjected to chaufeur visual observation distance (comprises night, storm, heavy snow, thick fog, curved tunnels, formed influence of worst observing environment and restrictions such as mountain area minor radius bend), also no longer be subjected to train speed and any restriction of drawing load carrying ability, the derail accident that causes except mechanical breakdown or chaufeur faulty operation because of train self, and do not have outside the accident (hitting train) of unexpected experience type of time difference as Rolling Stone, any other circuit danger, as circuit train signal mistake and disappearance, the train collision, knock into the back, the circuit landslide, unusual in the tunnel with the portal, flood, mud-rock flow, rail damage, bridge damages and fracture, the circuit foreign matter is invaded (the trees lodging that wind and rain weather causes, falling rocks, massif and the landslide of railway bank protection, electric pole collapses etc.), road vehicle and pedestrian invade railway in violation of rules and regulations, gate crossing accident etc. may cause the danger factor of accident, because chaufeur all can observe before the safety arrestment braking distance in advance, thereby before meeting with danger, there is time enough to take the hedging measure, therefore can avoids the generation of accident fully.
System of the present invention also possesses from monitoring function, when any factor causes camera or cable bad, the monitoring picture of this camera disappears on the monitoring screen AT STATION or occurs unusually, and the station, area under one's jurisdiction just can be known this place on line immediately, and something unexpected happened, can in time handle.And train driver also can from the disappearance of the video image picture of this camera or unusual find dangerously in advance, take corresponding measure.
When system of the present invention is used for subway and city rail traffic, except the advantage that prevents line accident, the outstanding especially main advantages that prevents the station accident is more arranged: after adopting system of the present invention, because chaufeur can observe the realtime graphic at station, the place ahead in advance, therefore just can take the hedging measure in advance.The picture Korea S the sort of station of Taegu's subway ignition retard, fully loaded train also pours the station that catches fire, and the result causes the especially big horrible disaster of hundreds of people's injures and deaths, if there is system of the present invention to supply chaufeur to observe the unusual condition at station, the place ahead in advance, obviously is avoidable fully.
Subway (city rail traffic) is because the characteristics of passenger flow are different with railway, there is very large upper and lower class peak passenger flow, in peak period, the station passenger flow volume is very big, the stream of people is crowded to capacity, be the main scene of subway (city rail traffic) accident, because the station accident has accounted for significant proportion in subway (city rail traffic) accident, this advantage of the present invention has special effectiveness to the safety that improves subway (city rail traffic) operation.
Under the normal prerequisite of system works, from then on free poor circuit danger factor will no longer jeopardize train safe.Train danger from now on is mainly from following a small amount of low probability factor;
1, train self accident such as derailing, fire, blast etc.
2, do not have space parallax, directly hit the danger factor of train with train in advancing, as train drive middle falling rocks into, landslide takes place suddenly, directly hits train.Or road vehicle drops from the top, directly hits train.
3, terrorist activity
Even the accident of these types takes place, system of the present invention also can bring into play significant role in rescue, at first be that station security monitoring person and control center can be in very first time discovery accidents, and determine the accurate position of accident site and the infringement presentation degree directly perceived of the scene of the accident immediately.Next is to speedily carry out rescue work with tissue with the rapid warning of visual information mode, and the 3rd is in the rescue process, can carry out field monitoring and command scheduling with visual means, accelerates the speed of rescue.
