11. distinguish the by stages of specifically automatically closing up that the accident of finding of should dispatching officers immediately behind the accident generation section takes place.
Two. reverse signalling set and principle of work
1, the structure of reverse signalling set
1) reverse signal general introduction: reverse signal be arranged on run signal machine back than the run signal machine at the bottom of but higher than departures and shunting signal, by red light, flash the four lamp tristimulus signal machines that red light, blue lamp, white lamp constitute.As accompanying drawing 1,2, shown in, along surveying device in the operation vertical direction signal one klaxon JD is arranged, the outer survey is equipped with red location of accident display lamp BDD.Do not show at ordinary times,, show red always when after this signal generation overrunning of signal accident.As accompanying drawing 3, shown in, front and back track relay (GJQ, GJH) is housed respectively from run signal machine front and back≤10m place on the insulation rail of reverse signal two by stages before and after the run signal machine, A, A, E, E are the point of connection of GJQ, GJH and forward and backward track.As accompanying drawing 4, shown in, the quad that lay on road along the line is reverse signal signal control line NXK.Wherein three U, L, H link to each other by the place ahead run signal machine Huang, green, red light relay normally open contact U, L, H positive source.Another root B line and the interval uplink and downlink direction two station control desk shuttle trains red light alarm device that advances rashly links to each other.
In the signal control cabinet of reverse signal control convenience device below the run signal machine.Each run signal machine all disposes a reverse signal, but the instation shunting signal is not provided with reverse signal, also should close the power supply of its reverse signal when starting signal uses as shunting signal.The contrary station signal and the interval reverse signal of starting signal constructed, size is identical, to show the difference with shunting signal.
The power supply of reverse signal is by obtaining in its run signal machine signal control cabinet.When run signal machine (comprise station signal) when occurring as conflicting signal, whether the power supply of its reverse signal turn on three, in go through.
The reverse signal of home signal is set up ZKJ and the ZFJ relay by the control of signaling at stations control desk.ZKJ cites approvingly and leads the control relay that enters the station, and need guide when entering the station at train to start.ZFJ claims to block the relay that enters the station, and it acts on three, middle detailed description.
Relevant reverse signal control line in the station chain problem three, middle detailed description.
2) the former device of reverse signal explanation: as accompanying drawing 3, shown in, B, U, L, H are quad, promptly reverse signal control line NXK, B are the train red light alarm line that advances rashly, U, L, H are respectively the reverse signal control line that links to each other with the run signal machine.
The two windings point that the subregion insulated track links to each other automatically closes up for the place ahead insulated track relay that the A of GJQ, A are arranged on run signal machine dead ahead≤10m place and rear.GJQ is the place ahead insulated track relay.GJH is a rear insulated track relay, and its two E, E contact are connected on the subregion insulated track two ends of automatically closing up from the place ahead at run signal machine≤10m place, the run signal machine back side.

8For diode require rectified current 〉=300ma withstand voltage＞100V.D
6For reverse red light choked flow diode requires rectified current 〉=3A, withstand voltage＞100V.K is that the control relay in switching relay and the run signal machine is general.UN, LN, HN are that the colored lights relay in reverse indigo plant, white, red light relay and the run signal machine is general.YJ also is universal for alarm crimping relay.YJA, GJA are that reverse signal switching relay is also for universal.BJ is an alarm relay, is power-off delay relay, delay time 〉=300S, and wherein BJ1 relay time-delay break contact is answered 〉=10A by electric current.SJ is for flashing the red light relay, SJ2 contact current 〉=3A.Mixed signal control relay BSJ is the logical type outage time delay closing relay delay time 〉=4S that answers.BDJ is universal alarm lamp relay, and BDD is alarm lamp power 〉=15W.SHD, HND, UND, LND are reverse red light, red light, blue lamp, white lamp, the power 〉=25W of flashing.TA is for eliminating alarm button, and device is in signal control cabinet inside.JD is a siren, requires to have the enough sound intensity and stronger directivity.
3). reverse signal is in the connection in interval: at each subregion that automatically closes up, the reverse signal control line NXK that is made up of B, U, L, H line between the reverse signal is by as accompanying drawing 4, shown in connection.The NXK control line accompanying drawing 7, in be reduced to one.NXK the interlocking in station district will be three, middle detailed description.
2, reverse signal operating principle is analyzed
As accompanying drawing 5, shown in, a, b, c, d, be the signal position, the element of corresponding reverse signal marks with subscript a, b, c, d down, is indicated as the place ahead insulated track relay of the reverse signal of a as GJQa.GJQa1 shows its first group of contact.The reverse signal control line of a, b subregion marks with Lab, Uab, Hab, Bab respectively.
Press below accompanying drawing 3,5, shown in analyze its principle of work, if the train I enters the subregion 1 that automatically closes up fully, be that train I afterbody breaks away from GJHa range of control (getting over 20m from signal a rear approximately), and the locomotive of train I gets electric, GJQa, GJHa from the distance of signal b greater than range of control (from the about 20m in signal b the place ahead) Ka this moment of GJQb and all is failure to actuate, GJHa5, GJQa2 disconnect, the YJAa dead electricity, YJAa2 disconnection, GJAa dead electricity, GJAa1-3 closure, GJAa4-6 disconnects.While GJHa1 disconnection, BJa dead electricity, BJa3-4 closure, Ka2 closure are so the power cathode of UNa, LNa, HNa and the reverse signal of a is connected.But the Lab among the reverse signal control line NXK between a-b connects by Lb and the reverse signal positive source of b, so the LNa relay of reverse signal a gets the electronic LNa of work closure, LNDa display white signal, informs the train guard of train I.
Near train I head advances to the b signal, with A, the A short circuit of GJQb, GJQb1-2 closure, but YJAb dead electricity, the GJAb dead electricity, the GJAb1-3 closure, GJAb4-6 disconnects, so Lab is a high level, makes reverse signal a still show white lamp.
When train I head passes through signal b, the A of GJQb, A, the E of GJHb, E short circuit is simultaneously moved track relay GJQb, GJHb simultaneously.Since the conversion of Hb need certain hour (by letter rule≤4S) so Kbi disconnects, and YJb dead electricity, YJb2 disconnect, BJb, SJb, HNDb, GHJb, JDb all not the electric warning that can not advance rashly.The action of GJQb, GJHb makes the GJQb1-3 closure, the GJHb4-5 closure, that YJAb gets is electric, GJHb3 is closed, YJAb2 is closed, electric, GJAb1-3 disconnection that GJAb gets, YJb2 disconnects, the YJb3-5 closure, the GJAb4-6 closure, reverse signal control line between a, b is accepted by the next run signal of c signal, and the closed mixed signal control relay of GJQb3 BSJb gets, BSJb1 disconnects, and YJb6 disconnects no level and leads to Uab, Lab by b, and assurance train I is looked reverse the signal and the locomotive bus attendant of a signal and watched from a height or a distance synchronously.
When the train I was passed through signal b, GJQb dead electricity, GJQb1-2 disconnected, the YJAb dead electricity, YJAb2 disconnection, GJAb dead electricity, GJAb1-3 closure, and GJAb4-6 disconnects the signal of reverse signal control line a, b received signal b.Make the reverse signal of a show red light, the train guard of train I is watched from a height or a distance the reverse signal synchronous with the c forward signal of b at this moment.This moment, the train I broke away from the control to GJQb, and GJQb3 disconnection, BSJb dead electricity, BSJb1 time-delay 4S closure if the train I is normally moved, have broken away from the GJHb range of control after 4 seconds.Promptly GHJb1 disconnects when BSJb1 is closed, and the YJb6 disconnection, and the reverse signal control line between a, b does not have the warning signal of mixing level.
When the train I entered between block section 2 fully, the E of GJHb, E recovered, and do not produce any influence, and it is synchronous that the train guard of train I is looked reverse the forward signal of the signal of b signal and c.
If the train I enters by stages 1 fully, signal b shows amber light.As previously mentioned, the reverse signal of a signal will show blue lamp, till train I afterbody enters by stages 2 fully by signal b.At this moment, the reverse signal of the b that train guard is looked of train I is synchronous with the forward signal of c.
If the train I between block section 1, signal b shows red light.At this moment, Kb1 closure, GJHb2 closure, YJb get electric and self-insurance, YJb2 closure, YJb3-5 disconnect between a, b reverse signal control line only Hab be high level.Because YJb3-5 disconnects, and has cut off the reverse signal that the c signal rearward provides.If this moment train I overrunning of signal machine b red light, GJQb, GJHb all move, GJHb1 connects, that BJb gets is electric, it is electric that SJb, HND, JD are got, the reverse signal of b show a red light, flash red light forwards the train operation vehicle commander report to the police.The orientation of JD ring siren is to the alarm of train I locomotive bus attendant, this moment GHJb get electric, GHJb1 is closed, BSJb1 disconnects but the YJb6 closure, so power supply passes through D
4, D
5Make that reverse signal control line U, L, H line are high level between a, b, white, blue, the red trichromatism of the reverse signal aspect and indication of a signal this moment, the expression train I locomotive danger signal that advanced rashly, the train guard of train I should be taked the emergency braking measure immediately.That BJb gets is electric, make that BJb2 disconnects, the BDJb dead electricity.BDJb3 closure, the location of accident display lamp that is installed in the b signal outside show red, and BDJb1 is closed to report to the police by the interval station of B alignment uplink and downlink direction.After the train I of the red light that advances rashly entered the subregion 2 that automatically closes up fully, GJHb dead electricity, GJHb1 disconnection, GHJb dead electricity, GHJb1 disconnected, and it is high level that the reverse control line of a, b only has Hab.Because BJb is a power-off delay relay, delay time 〉=300S.So the time BJb1 still closed, reverse warning signal 〉=300S that the train guard of train I is visual, listen b.
If train fully at the subregion 1 that automatically closes up, has the train II to take at the subregion 3 that automatically closes up.As shown in Figure 6, and the train II is parked near near the signal c, within the GJHc actuation range.That GJHc6 closure, GHJc get is electric, GHJc1 is closed, the BSJc dead electricity, the BSJc1 closure, and Ubc, the Lbc of reverse signal control line b, c section is high level, and this moment, GJQc did not move, and reverse signal control line b, c section Hbc also are high level.After train I locomotive was crossed signal b steady yellow, the reverse signal aspect and indication of a was white, blue, red trichromatism, shows train I head from by stages distance of automatically closing up of the place ahead train II afterbody spacing less than, and the train guard of train I should be taked the emergency braking measure.
When train II afterbody has entered 3 intervals, but afterbody does not break away from GJHc, as long as the train II is moved with normal speed, because GJQc recovers, GJQc3 disconnects, the BSJc dead electricity, but BSJc is a power-off delay relay, closure behind the BSJc1 time-delay 〉=4S.So the time BSJc1 still disconnect, after four seconds, the control (about 20m) that the train II of normal operation has broken away from GJHc, reverse signal control line b, c only Hbc are high level.If train I locomotive is crossed yellow signal machine b, the reverse signal of a signal only shows single redness, and the reverse signal that the train guard of train I is looked red by blue stain.
The interlocking problem that reverse signal showed white, blue, red trichromatism signal when blockade was entered the station 3, middle discussion.

The effect of button TA is, when train advances rashly after the red light accident occurs at this signal, after stand side report the higher level to dispatch officers to find out, presses TA the location of accident display lamp is extinguished, and BDJ gets electric self-insurance, the BDJ1 disconnection, and recovery B line level is zero.
After the accident that advances rashly takes place, more than the alarm continuity 300S.After if the scene of the accident is got rid of, can continue operation, then after the train between emergency area is left this interval of automatically closing up successively, after entering last interval fully, the warning signal machine is shown after the amber light, the self-insurance release of YJ, follow-up train can be gone slowly and be entered this interval in its place ahead this moment.
Should not decide not crosstalk mutually from the distance of signal both sides before and after GJQ and GJH were installed in signal.By the insulated track relay parameter of having used, the distance between GJQ, the GJH is answered 〉=20m.
For simplicity, accompanying drawing 3, in each relay flywheel diode all do not draw.
Three, reverse signal interlocking in the line
1. special-purpose shunting service signal is not provided with reverse signal in the station.Departure signal machine in the double station of doing shunting signal should cut out the power supply of its reverse signal shunting when using.
2. the ZKJ that sets up of the reverse signal of home signal, the effect of ZFJ
1) ZKJ claims the station control guiding relay that enters the station, and when the needs guiding was entered the station, by the control of signaling at stations control desk, ZKJ got electric, as accompanying drawing 3, shown in.ZKJ1-2 disconnects, need locomotive bus attendant that guiding enters the station to get in touch with train guard by interphone mode such as blow a whistle, after the affirmation, with specified speed by guiding home signal, because ZKJ1-2 disconnects, the YJ of this signal, BJ, SJ, GHJ, JD can not move warning.
2) ZFJ claims station control to block the relay that enters the station: a) at the double-line automatic block section, as accompanying drawing 3,8, shown in, when all station tracks, Dang Zhan district all take, need to block home signal b.The blockade program is as follows, by signaling at stations control desk signal watch keeper press that the ZFJ button makes that Hb connects, the b run signal shows red light, Kb gets electricly, Kb1 closure, YJb get electric self-insurance.After action was finished, that ZFJb gets was electric, ZFJb1 disconnects, the GJHb action, the GJHb6 closure, and GHJb gets.Simultaneously, because ZFJb2 disconnects, cut off warning circuit and do not produced warning.Because YJb6 closure, GHJb1 closure, the Uab that makes NXKab, Lab, Hab are high level.Train I head is crossed visual reverse signal whitening, indigo plant, the red trichromatism of train guard of train I behind the signal a, and train guard has the right to take emergency braking, the train I can not advanced rashly block red signal machine b.
The red light b once advance rashly is because GJQb action, and that GJQb5 closure, GJHb get is electric, GJHb1 disconnects, GJQb4 disconnects C
4The ZFJb time-delay is discharged, when the train I is crossed red signal machine b, do not report to the police.The train I is if cross b, and then GJHb moves, and GJHb1 is closed to report to the police.Capacitor C
4The RC circuit time constant of forming with ZFJ be ZFJ opening time 3-5 doubly.
B) at the single line automatic block district, as accompanying drawing 3,9-1,9-2, shown in, (see Fig. 9-1) during all track occupieds of Dang Zhan district, or up handle enter the station (seeing Fig. 9-2), should block descending home signal b, the descending blockade of the pressing ZFJb button that enters the station.After the blockade, make descending incoming train I can not cross signal b.Only when up enter the station handle finish after, can the descending blockade of entering the station of release.The structure of detailed circuit can be implemented by above-mentioned principle.
3. the interlocking of reverse signal and station district signal
1) the enter the station interlocking of reverse signal and starting signal: when main track or arbitrary side line connect car, the reverse signal control line of this station track starting signal and the reverse signal of home signal all should be connected fully.Midway the reverse signal control line of other station track of intersecting of all track switches of process all should by the switching relay ZHJ that sets up through electrically operated derailleur disconnect.As accompanying drawing 7, shown in, a is reverse signal control line for the Xin Ji Xi XK that enters the station, ZHJ1,2 is the switching relay of 1, No. 2 track switch.Accompanying drawing 7, shown in, for handling the enter the station NXK interlock method of operation of main track.
2) the reverse signal of starting signal and the interlock method and 1 that moves the place ahead first signal) with.
4. the processing of conflicting signal
When 1) run signal machine single, the double-line automatic block section occurs as the conflicting signal machine, should turn-off the power supply of its reverse signal without exception.
2) single line automatic block district, a direction is handled and is entered the station when connecing car, and other direction might be swarmed into the power-off of reverse signal of conflicting signal machine of the station track of train.Shown in the accompanying drawing 9-2.
When 3) arbitrary idle station track, the side of station and approach line are connected, when not allowing to handle train and enter the operation of entering the station of this station track, close the reverse signal of this station track conflicting signal machine.
