Abstract
An automatic control system for trains features that a common unlock loop is set up between two light signals belonging to different directions and separated from each other on a single-rail region for feeding relative collimation signal to approaching train. Said unlock loop is arranged in B3 structure mode by means of continuous wire. In order to allow the train to pick up its private telegram from the signals in common unlock loop, an ID of collimation signal is sent to it in advance. The ID is also contained in telegram. By comparing. what telegram is needed for relative train can be judged. By proper synchronization, it is avoided that the telegrams from different collimation signals are simultaneously fed into the continuous wire.
Description
The present invention relates to a kind of a place ahead sight signal near section in transmit the train automatic controlling system of information continuously to train, particularly shift to an earlier date release for the signal aspect and indication that restriction is travelled, adopted one to guide to and sight on the signal,, and have at least one and be symmetrical in the lead that track centre is arranged at the continuous conductors of side signal transmission along track to the limited extension of arranging.
At German journals " Signal+Draht " 84 (1992) 12, a kind of train automatic controlling system is disclosed in 397 to 399 pages, this system is at the other point type train automatic controlling system that disposed of the wigwag of railway section, utilize this system can be, the train locomotive that the signal aspect and indication that sent and some sector data are together passed to process by the mode of induction.In order to make one can after signal aspect and indication becomes driving from parking, quicken again at once at the locomotive that moves under the stop signal, laid continuous conductors in wigwag front and cruising side in the opposite direction, the signal aspect and indication that sends can be delivered on the approaching locomotive through this lead; Allow this signal replace original signal then on locomotive, the signal-parking brake signal of sighting that promptly before had been transferred to locomotive shows.Continuous conductors is positioned at by the right side rail of track outside, can be by same locomotive antenna scanning, and this antenna also can receive the signal of point type train automatic controlling system.If can on both direction, travel along track, then in order to transmit two signal aspect and indication on the opposite travel direction, corresponding point type train automatic controlling system and continous way train automatic controlling system to be set, so that transmit the information of signal at the opposite side of track.Because the physical dimension of the antenna of section and locomotive, each locomotive with corresponding receiving device can only be received in the signal information of sighting in its travel direction the place ahead.
Also disclose a kind of similar train automatic controlling system in 83 (1991) 7/8,194 to 197 pages of " Signal+Draht " magazines, wherein the continuous conductors of limited extension is not in outside the track, but between rail.A lead is laid along track centre, and another root follows to be sailed direction and lay in the rail of right side rail.Two leads intersect with predetermined interval; The arrangement of this continuous conductors is called as B3 system of laying (referring to magazine " Schienen der Welt " 1972,6,428-430 page or leaf).The continous way train automatic controlling system of describing in " Signal+Dra-ht " magazine is used for equally in advance release being carried out in the speed demonstration of signalling, but only is used to the transmission zone data.This scheme is not used the additional point type transmission system that is laid on the section, and this point type transmission system is when continous way signal transmission et out of order, often will be as stand-by system.
The advantage of the continuous conductors of laying according to the B3 system of laying is, the lead that is positioned in the middle of the track can be used for receiving and transmission information from locomotive, and is subjected to the damping of guide rail to influence very little by the information that this central conductor sends and receives; The electric interfering field that electric current produced of Liu Donging is very little to the influence of the locomotive receiving wire on the middle position in orbit.But the shortcoming of this system is that this continuous conductors structure itself can not successfully be discerned by the locomotive through this section owing to the cause of the physical dimension of the antenna on locomotive and the section.When this lead was used to transmit information corresponding to the train that travels in different directions, the continuous conductors of this structure also was difficult to be mounted.What this situation occurred may be, for the signal that is used for the unlike signal transmission direction separated by a distance, be provided with or separate separate lock loop or the shared lock loop of separating, signal is introduced from both sides.
Task of the present invention is, makes a kind of train automatic controlling system, and it can select to transmit the information on the different travel direction.
The technical solution of above task is: continuous conductors is with intermittently and the mode that replaces, and sights signal on sequential delivery section on the different sense; Before the continous way information transmission system on the travel direction, the point type information transmission system preferably is set, so that sight identifying code signal, can identify the signal of sighting that is positioned at travel direction the place ahead according to this heading code locomotive to locomotive transmission through this system; Locomotive is being stored the identifying code signal of being discerned of sighting through before sighting signal accordingly at least; Sight signal will coorespondingly with it sight identifying code signal respectively feed-in in the information telegram of separating lock loop that it begins; Locomotive is only accepted this information telegram, the content of sighting identifying code signal of this telegram with before be transferred to locomotive to sight identifying code signal identical.Selectivity to information transfer obtains in the following manner, locomotive can be learnt the signal of sighting that instructs its operation in advance, comprise a heading code from the information telegram of sighting signal feed-in continuous conductors in the place ahead, this sign indicating number can be sighted signal to each and make mark.To compare through the known identifying code signal of sighting of identifying code signal and train of sighting of continuous conductors transmission, can make train in the information telegram of sending to it, only select its special-purpose telegram.
The further formation of train automatic controlling system of the present invention and scheme see that dependent claims is described.
In order to transmit the information telegram, sight signal from two and be provided with a shared continuous conductors, sight information telegram that signal obtains from the shared wire loop of both sides feed-in from two, the wire loop end is through the emission amplifier feed signal of special use, and the mouth of this amplifier and the impedance phase of wire loop mate.This structure can prevent to produce reflection, and realizes best signal transmission between section and train.
Present the emitter of sighting signal in the different conductor loop or on same wire loop for two,, make and sight signal phase mutually synchronization by level monitoring or special synchronizing signal monitoring.The unlikely chance of information telegram that two emitters are sent overlaps, thereby can't read.
One of two emitters are controlled by the clock switch that the information telegram by another emitter is triggered, and this clock switch can make the information telegram of this emitter receive on the wire loop in its additional switching time.An emitter is opened directly or indirectly, if another emitter does not just transmit by the signal of another emitter.
In separating a kind of special structure of lock loop, shared continuous conductors only is arranged on the finite part of release section, the remainder of release section is by special continuous conductors loop control, this loop links to each other with the special mouth of affiliated emitter, and this emitter is also to shared continuous conductors feed signal.The occasion that this scheme is suitable for is, separating lock loop or common type through affiliated emitter to separation type, to separate the wigwag of lock loop feed-in comparatively intensive, but the release section is greater than the interval of wigwag.
Contrast example shown in the drawings below, the present invention is described further.Accompanying drawing is:
Fig. 1 is illustrated in a shared structure of separating lock loop between two wigwags;
When being illustrated in indirect control, realizes Fig. 2 the principle of phase mutually synchronization;
Telegram chart (Telegrammdiagramm) under Fig. 3 represents;
When being illustrated in direct control, realizes Fig. 4 the principle of phase mutually synchronization;
Pulse chart and telegram chart under Fig. 5 represents;
Fig. 6 represents the release scope in plurality of sub loop.
Fig. 1 is illustrated in two wigwag S1 and S2 spaced apart on the monorail section, be respectively applied for different travel direction; Wigwag S1 shows train signal, and wigwag S2 shows stop signal.Be provided with point type train automatic controlling system ZUB1 and ZUB2 on the next door of wigwag, the signal aspect and indication of sighting signal under this system will connect respectively by induction mode passes to locomotive, and this locomotive driving is on the section opposite with the direction of wigwag transmission.For the signal aspect and indication release to connecting when needed, wigwag S1 and S2 are transported to the preferably shared two ends of separating lock loop AS through affiliated control assembly SG1 and SG2, and this is separated lock loop and lays with the B3 frame mode in orbit.In order to guarantee the unobstructed of signal transmission, the mouth of two emission amplifiers of control assembly is conciliate the impedance phase coupling of lock loop.Two to sight signal separate but mutually synchronously with intermittently and the mode that replaces, with the signal aspect and indication that transmitted and other locomotive control signal conveys to shared separating in the lock loop AS.Separate lock loop if locomotive is positioned at this, then sight and receive the information telegram the signal from two; But have only one to send in this telegram, promptly be in the telegram that wigwag sent on the locomotive driving direction to this locomotive.According to principle of the present invention, be the telegram of selecting to be transmitted, at every turn before reaching the release section, in a suitable manner, preferably by a point type train automatic controlling system, for example ZUB3 correspondence travel direction from right to left, transmit a so-called identifying code signal of sighting and give locomotive, make locomotive when delayed completion is collected mail the breath telegram slightly, select needed information telegram, promptly be in the telegram that signal S1 is sent of sighting in travel direction the place ahead by separating lock loop.This is sighted identifying code signal and is made up of a data code, and it can be received by a transmission system according to the travel direction of locomotive, and is continued to be stored on the locomotive, till locomotive crosses cooresponding aiming point.
In by continuous conductors information transmitted telegram, transmit to sight in the signal and sight the corresponding identifying code signal of sighting of identifying code signal with travel direction the place ahead is transmitted, and locomotive identifies relatively from these two contents of sighting identifying code signal, and whether the telegram that is receiving is used for its travel direction or is used for the direction opposite with travel direction.Locomotive can only accept to belong to the information telegram of its travel direction, and with oppositely directed eliminating.
Utilize train automatic controlling system of the present invention that the signal transmission is carried out through a continuous conductors that is symmetrical in the track centre laying according to travel direction.
As mentioned above, the launch pad of transmission signals must the phase mutually synchronization on common return, so that make the information telegram of sending can be not overlapping in time.This synchronous realization that for example can pass through indirect control synchronously, as shown in Figures 2 and 3.Wherein sight the pairing control assembly SG1 of signal S1 and for example can be used as main control component, then conduct is from control assembly to sight the pairing control assembly SG2 of signal S2, and it is according to the signal work of main control component SG1.Main control component SG1 will become an information telegram TS1 from the information aggregating of sighting signal SG1 or point type train automatic controlling system ZUB1, and this telegram is transferred to through its amplifier separate lock loop AS; Separate lock loop and repeat this information telegram with fixing interval t1, this was about for 1 second at interval.Receive from main control component SG1 from control assembly SG2 and to be switched to the telegram level of separating lock loop, and according to its additional clock switch of this level triggers that receives, t2 delay time of this switch was approximately for 0.5 second.Along with by the time-delay process that clock switch added, the information by point type train automatic controlling system ZUB2 is received on the continuous conductors with the information telegram TS2 that the information of sighting signal S2 constitutes from control assembly SG2.The information telegram of this information telegram and main control component is the same, comprises each cognizance code of sighting signal, and from this code, telegram is transferred on the continuous conductors.
The another kind of mode of two control assembly phase mutually synchronization is seen Fig. 4 and shown in Figure 5.Wherein from control assembly SG2 to whether existing the information telegram of main control component SG1 not monitor, and allow main control component generate, and the information telegram TS1 by main control component, after for example passing through t2 (about 0.5 second), send an energizing signal TS1
*, and this signal sent into continuous conductors.After receiving this energizing signal from control assembly SG2,, in continuous conductors, send into an information telegram TS2 by affiliated amplifier.
In the embodiment shown in fig. 6, two are sighted signal is to be transmitted by a shared lock loop of separating, and the interval of two signals is less relatively, but the release section is more much bigger than the distance between two wigwags.From this reason, except two wigwags have relatively short shared separating the lock loop AS, also has the special lock loop of separating, but this loop receives only the signal of a control assembly or another control assembly, that is to say, side signal transmission from left to right additional separated lock loop AS1 and is provided signal by control assembly SG1 to pairing, and the lock loop AS2 that separates that another side signal transmission makes progress provides datagram by control assembly SG2.In this datagram, aiming point is pairing to be sighted in identifying code signal is also included within, and no matter whether above redundant mesh sends mis-information.The reason of this way is, locomotive can not be distinguished special and the shared lock loop of separating, and data processing method must be identical in two loop sections.Special loop links to each other with the special-purpose mouth of affiliated control assembly through isolating transformer T.With shared and independently separate lock loop and comprise also that in case of necessity the release loop sets of different length lumps together, can make the wigwag configuration-independent on release loop section and the track, thereby adapt to the characteristics of section, make the present invention obtain best enforcement.
