Abstract
The invention relates to an objective brake method for braking train/locomotive to parking point, in the following cases, i.e. behind a parking point (L), route protection glide section (D1) concerned in common brake is not provided, but only a shorten route protection glide section (D2), then the method will indicate the train (Z1) driving for the parking point to execute stop break in a reduced braking deceleration (b2). Thus, when the train glides by the parking point, the concerned stop speed of the train which has run into the route protection glide section is reduced and brings following effects: shorter route protection glide section is provided for the section of gliding. The method can realize that even when the route protection glide section becomes shorter, the train can pass the route to the parking point before reaching the braking implementing point in a relative higher speed, so that the method can improve trafficability for railway section.
Description
The present invention relates to a kind of as claim 1 method as described in the preamble.
After the destination of train route, remain with a so-called entry protection in advance and slide section; this section is used to avoid the driving danger of following type; be that train accurately stops at the echo signal place, and (because the trainman estimates the mistake of deceleration and stopping performance) be after several meters parkings.Entry protection slides the orbit element (track switch of section; the crossing; track section) according to present practice and the same being protected of element that belongs to real travel way; logical component that be provided with by inside in the centralised arrangement in other words, corresponding is with these orbit element lockings and be locked in correct position; and detect it and whether be in idle condition, protect it to exempt from the locomotive motion and the oppositely directed locomotive that cause side collision and move.The shortest length that this class entry protection slides section depends on the speed of entering the station basically, when sliding by point station, is necessary for this train/locomotive that slides and sets the speed that enters the station.In the regulations of Railtrack, should make regulation in the minimum spacing that entry protection slides between section back, the real dangerous point at main running signal lamp that there stops and those as required to those trains.(52 (1960) the 8th phases of Signal+Draht, 133 pages to 144 pages).Therefore the main running signal lamp should be located at 100m place before the reverse track switch at least, and route crossing or be parked in the preceding 200m place of tail end of the train in the station.
Each point station for a main running signal lamp place can have a plurality of possible entry protections to slide section (54 (1962) the 2nd phases of Signal+Draht, 17 pages to 39 pages) respectively.Can optionally select these entry protections to slide section.The end of the selected entry protection section that goes out exerts an influence to signal or additional signal control, so as can according to different length or in orbital position different entry protections slide the signal aspect and indication of the auxiliary indicator of section control example such as main signal.Each additional signal follows to sail on the signal that direction is positioned at the rear at one and shows as speed and to be expressed out and to urge the trainman to pay special attention near point station the time.This external entry protection slides under the situation that section shortens, and reduces the speed that moves forward that locomotive allowed, and when sliding the point station of section near shorter entry protection at least point type ground (discontinuously) monitor it and be no more than predetermined numerical value.This process is 150m place before the main running signal lamp at least, however at least before dangerous point the 450m place carry out.If can not reach necessary distance from dangerous point, in signal level (Signalh he), remain to be provided with an additional speed scrutiny program section so, this speed scrutiny program section forces its forced brake when train advances rashly with excessively high speed.
Reduce train and slide the speed that moves forward that is allowed in the track section in section the place ahead at the entry protection that shortens; near point station the time, detect simultaneously in conjunction with the speed of carrying out one or many; this is only for for the purpose of the safety of railway traffic; but since train only with the speed that reduces to going to the point station place to move, this can cause driving to hinder once in a while.
The objective of the invention is to; in the framework of automatic train stop, provide a kind of, enter the station even if make to slide still can allow at first to travel in the track section of train in the place ahead, destination under the situation that section shortens with the speed that does not reduce at entry protection as claim 1 method as described in the preamble.
The objective of the invention is to realize by the described feature of claim 1 characteristic.By preestablishing the braking characteristics curve with less braking deceleration, the train that sails for point station will begin braking procedure ahead of time than in the past, and with than at present lower speed near point station.Because the speed that moves forward that remain to be set this moment is lower, the shorter entry protection of train that train also only needs to have higher braking deceleration relatively usually slides section.
The preferred embodiment and the well designed of the inventive method are provided by dependent claims.
The present invention is described in further detail by the accompanying drawing illustrated embodiment below, in the accompanying drawing:
Fig. 1 brakes the sketch of point station in normal way for train;
Figure 2 shows that a corresponding train with lower braking deceleration braking.
Can see the railway section shown in the part simplification in Fig. 1, it for example is divided into isometric three orbital segment A, B, C.Train Z1 follows and sails direction and advance on this railway section from left to right.Other in this railway division have a colour light signal machine L, and train should stop herein.For realizing this purpose, send stop signal and notify its current distance to train with the color light signal of mode and method connection arbitrarily L in advance apart from color light signal L.This train Z1 is for example 0.9m/s at himself braking deceleration b1
2The basis on calculate a braking characteristics curve, stop at the echo signal place according to braking characteristics curve train.For the too high for some reason braking effect of having estimated by its regulating control of trainman; thereby cross point station; an entry protection is set after this point station for this reason slides section, its idle condition is subjected to the monitoring of a centralised arrangement or a control center.Have only when entry protection slides section D1 to be expressed when being in the free time, just allow train Z1 to move forward to color light signal L place fully; Otherwise train is braked to quiescence at another nearer color light signal place.
Suppose that the signal that is sent by this color light signal L is a home signal that enters the Railway station; and railway section C has comprised one section of station track circuit in the platform zone at least; then the situation shown in Fig. 2 may take place; promptly because there stops having a train Z2, it is occupied that the entry protection that provides for common drag slides the part of section D1.Similarly also may to occur in this track section C be a track switch for example to situation, and this track switch is when being included in another route.Slide section D2 for train Z1 also only leaves an entry protection that shortens this moment.According to technical director of the present invention, no longer send one and sail section A into, perhaps follow and sail the signal that direction enters nearer section with the speed of entering the station that reduces to the train Z1 that is advancing, but train notified, it should be with the braking deceleration that reduces, for example b2=0.4m/s
2Move forward to point station.Though train is than the more Zao braking procedure that enters of embodiment shown in Fig. 1, this train is the same with train in embodiment illustrated in fig. 1 before the point that arrival is taked to brake, and moves forward with the speed that does not reduce.Enter front one section with the speed of entering the station that reduces relatively like this, it is shorter that train moves forward to the preceding shift time of point station.Because train is more lentamente near point station, can think that train may be estimated because of mistake the trainman under the situation of braking potential to remain to be set with one, obviously than the lower maximum speed of the situation of the illustrated embodiment of Fig. 1 by this point station L.For this reason for train, can set one and slide section D2 than the shorter entry protection of entry protection section D1 shown in Fig. 1 with the braking of the braking deceleration that reduces.Therefore this train Z1 also can be reliably before dangerous point under the situation of sliding, and this situation is that train Z2 arrives quiescence before.The prerequisite here is; the entry protection that distance between point station L and dangerous point Z2 is used for braking deceleration b2 slides section D2 length; and in time, just before implementing point by braking by the color light signal L that is connected provide to train Z1 close the parking signal aspect and indication, apart from the information aspect destination distance and the braking deceleration that remains to be scheduled to.These must guarantee by control system.Main information transmission is best in no electric wire mode, for example passes through radio, or by being layed in the transducer wire between the rail, or undertaken by the intermittent automatic train stop device.
Thisly be transformed into braking characteristics curve from braking characteristics curve as required and only depend on braking deceleration b2 with braking deceleration b1; common entry protection slides section D1 and for which kind of reason can not use; this reason may be; it is occupied in the embodiment of Fig. 2 that entry protection slides the rear end of section D1; there for example under construction or this entry protection to slide this section of section D1 included by another route, that route requires this section work to be different from the use that entry protection slides section D1.Be transformed into have the braking deceleration that reduces the braking characteristics curve can by for example with section A; the line idle indication device of B and C phase configuration carries out; this device recognize on the one hand track section C occupied or book it use; and then it is not enough to learn that entry protection slides the back segment part of section D1, shows that on the other hand the entry protection that shortens slides the track clear of section D2.Have only when these prerequisites exist, allow that just train moves forward to stop signal machine L with the braking deceleration that reduces.Also occupied if for example learn section B, do not allowed that then train Z1 moves forward to color light signal L place, but must be stopped in advance at another point station place.
In the illustrated embodiment, this is connecting the point station that an entry protection slides section and is representing by a color light signal.Whether such color light signal exists, to implementing the inventive method and having no effect.Important only is: locomotive should stop in a destination of determining and it can in time obtain corresponding information from a control desk.
Except sliding the section, an entry protection that is used for common service braking can not only keep one in advance in principle; but the entry protection that many different lengths have shortened slides section, and they are applicable to the braking characteristics curve with different braking deceleration/decel respectively.Available property according to the railway element, send the control desk of control command for the train that on a part of path, travels, according to the available property of track at that time, determine which braking deceleration allows for a train that moves forward to a point station, and give train corresponding message transport.Train self can calculate the point of required at that time enforcement braking, or is determined this point and corresponding range information transferred to a train that needs to consider that this braking is implemented by control desk.
