Description
The present invention relates to a kind of device that the railway current consumer was controlled and monitored to signalling technique safely that is used for.
Usually adopt the electron steering regulating mechanism to carry out the control and the supervision (Signal+Draht 75 (1983) 11, the 210-215 page or leaf) of railway traffic at present.This electron steering regulating mechanism is according to railway station master on duty's requirement, or answers exciting to the train that will travel on the highway section of operatorless device to send the order of travelling, respective track is provided, track is monitored, and after train crosses route release again.Identical with the situation of relay control and regulation mechanism, the component part that the control of the on-the-spot part of electron steering regulating mechanism (Feldelemente) and monitor unit are internal unit.Wherein with identical, be to realize by the safe switch circuit that adopts the relay technology to the control and the supervision of switch in the situation of relay control and regulation mechanism.The signalling technique reliability of switch control and monitor unit is by program safety with to the employing realization of safety method device; Program safety be based upon with the interval of regulation or or even the basis detected of incident control ground components and parts that all and control and monitoring process are interrelated on.The situation of the situation of wigwag control and switch control is similar.Here Bi Yao reliability also is to realize by employing and program safety to the safety method device.To detect all devices in the control part, the feeder line that leads to wigwag and signal lamp according to operational process.If require to be shorter than the sense cycle of operational process, then also can carry out detection until the signal lamp function.The reaction of monitoring device and annunciator is delivered to a computer system of judging, this computer system is relatively carried out analysis and judgement to signal by rated value/actual value, and makes respective reaction.
Even the electron steering regulating mechanism also situation with relay control and regulation mechanism is identical, adopt signal relay to lead to the break-make control of the heart yearn of current consumer so far always.This relay is to be the relay of railway signal technology field development specially, and the mutual rigidity coupling by the contact in this relay has guaranteed that normally closed interlock and normally open contact can be not closed simultaneously.This characteristic of signal relay be failure-free by other with the relay contact in other current return of contact forced motion to be monitored, the precondition that the contact position that for example is arranged on the signal relay contact in the control current loop is monitored.The sort signal relay is much more expensive than the general purpose control relay certainly, even under the situation of latter's reliable in structure, also is like this.This so far control relay fails to be applied in the railway signal field to the safety requirements strictness always, this be because can not guarantee one by the switch position of the contact of a circuit or a computer monitor in fact with the switch position unanimity of a corresponding contacts of this relay in the relevant current consumer current return of safety.Can not detect also is so far this security-related current return not to be adopted electronic switch spare, but adopts a plurality of series connected contact of safety relay or the reason of single contact usually.
The objective of the invention is to propose a kind of signalling technique safety control and device that monitors that railway is used of being used for.This device is enough to competent be specifically designed to control security-related in the railway, and needn't adopt special development for this reason, be proved to be the failure-free signal relay.Relay/contactless switch to the substitution signal relay is only selected according to electrical installation condition, reliability and expense.
The object of the present invention is achieved like this, promptly adopts a kind of device that the railway current consumer was controlled and monitored to signalling technique safely that is used for, and has following feature:
A) each current consumer current return has two series connected, mutual unaffected control, unsafe derailing switches of signalling technique at least, is used for the cut-off/close of current return,
B) two derailing switches by the computer system of a safety independently computer access control,
C) every of current return heart yearn contains a derailing switch in two derailing switches,
D) have an annunciator at least, be used to discern one by flowing through current consumer supply current or detect that electric current derives or by the detection voltage of indirect communication, that the depend on current consumer at least mode of operation of current consumer,
E) closed out of turn or open circuited derailing switch changes this detection voltage significantly corresponding to the detection voltage of adjusting under the switch position situation when the normal operation,
F) by the output signal of two computer access evaluation annunciators of trusted computer system, and computer system identifies the out of season cut-off/close of at least one derailing switch according to the annunciator output signal of not wishing in real time to occur.
The present invention is further illustrated by embodiment illustrated in the accompanying drawings below.In the accompanying drawing:
Fig. 1 is the local diagrammatic sketch of wigwag control and regulation part;
Fig. 2 is the local diagrammatic sketch of switch control and regulation part.
In the drawings for ease of watching, omitted the not too mark of necessary switch member of the present invention is described.
Wigwag LS shown in Fig. 1 has a permissive signal lamp LG and a dimmer LR, and these two lamps are alternately connected by a control and regulation mechanism.For this reason, these two signal lamps are connected with the internal unit of control and regulation mechanism by long feeder line L1, the L2 that schematically illustrates among the figure.In known manner, begin the regulating control S0 of sequential adjustment by control mechanism and S1 is used for signal lamp is carried out break-make control.Realize that by a trusted computer system connection of this regulating control, this computer system and other computer system constitute control and regulation mechanism jointly.Regulating control of a passage control of this computer system, and another passage is controlled another regulating control.In Fig. 1, represent the passage separation with dotted line; The dotted line then permanent current potential between each device of indication device is separated.
What these two regulating control S0 were different with prior art with S1 is, they be not have a forced motion often open signal relay with normally closed contact, but have the control relay of optional conversion of motion contact S0/1 and S0/2 and S1/1.Their machine design should make single changeover contact, and when it was fused a position, it no longer can commutate when relevant relay is transferred; Normally closed contact remains closed and open contact keeps disconnecting; This means that one when breaking down in the regulating control contact by mechanical fixation, and another switching contact of relay continues normal operation.Even under the situation that adopts the failure-free regulating control, it also is inevitable that this contact is killed one or another locational phenomenon; The fault that occurs will be shown.
Owing to adopt the unsafe regulating control S0 of signalling technique, S1, thus can not by with contact S0/1, S0/2; Other contact of the relevant regulating control that S1/1 cooperates is carried out failure-free to the normal operative condition of regulating control and is monitored.Be used for monitoring the switch position of regulating control of the wigwag current return of real-time connection so the computer system that monitors is designated, to realize detection to its function.This point is by the supervision of voltage is realized at present, and this voltage is to be formed by the supply current that flows on the measuring resistor Rx in the electric power loop of the signal lamp of real time monitoring in the measurement process.This measuring voltage is added on the window discriminator FD of a monitoring device U by a photoelectrical coupler OK3, this discriminator is judged real-time measuring voltage, and result of determination is continued to pass on two computer access of trusted computer system by photoelectrical coupler OK1.Computer system is read in and is flowed to its signal by the window discriminator, and identifies the out of season cut-off/close of at least one derailing switch under the situation of breaking down according to the appearance of current and undesirable information signal.The supply current that in the lamp current loop, flows when being switched on according to the signal lamp LR that shows stop signal among Fig. 1, computer system identifies by the information signal that is passed to it by the window discriminator, meets two the normally closed contact S01/1 of the open circuited regulating control S0 of condition of service and S02/2 and the normally closed contact S1/1 of the regulating control S1 that is disconnected equally is actually closed.If one in these contacts is subjected to fault effects to rest on other the switch position at that time, the electric current of dimmer of then flowing through is interrupted, or measuring resistor is by short circuit, thereby makes the window discriminator not wish the information signal that occurs at this moment to one of computer system transmission.The computer system of judging can identify when connecting permissive signal lamp LG, and a quilt in these contacts is killed on described position.Computer system is at first impelled regulating control S0 commutation by a computer access for this reason.If its contact is working properly, then S0/2 interruption in contact still is in the electric power loop of the dimmer LR of connected state, and contact S0/1 is with contact S0/2 changing-over; Dimmer still keeps on-state.But contact S0/1 not only cross-over connection contact S0/2, and measuring resistor Rx cross-over connection, thereby window discriminator FD is lower than predetermined threshold with examining and determine out when only connecting regulating control S0, and corresponding signal is passed to the computer system of judging.Simultaneously, contact S0/1 cooperates with contact S0/2 permissive signal lamp LG one pole is connected.If be subjected to fault effects this moment, because the heart yearn contact is added with voltage on the heart yearn that leads to the signal lamp LG that shows permissive signal, this will cause electric current after this to produce a pressure drop on measuring resistor Rx, and this pressure drop is collected by the window discriminator, and then computer system is given in announcement; Computer system is discerned out of order existence according to the out of season appearance of signal for information about.One welding consequence among two regulating control contact S0/1, the S0/2 is identical when contacting with heart yearn.For example working as regulating control contact S0/1 is fused on described position, then as-welded is identified when connecting regulating control S0, this is because be interrupted by the flow through electric current of permissive signal lamp LG of the regulating control contact S0/2 that is after this commutated, thus make the window discriminator add to unified of department of computer science do not wish at this moment the information signal that occurs so.When the S0/2 welding of regulating control contact was on described position, situation was similar.Only regulating control contact S0/1 commutation when connecting regulating control S0.This has hindered the connection of permissive signal lamp LG, this be because this contacting be not to lead to the connection that normal lamp is sailed signal lamp LG, but lead to the connection of dimmer LR.
Regulating control contact S1/1 is fused and makes that on one or another position it is impossible connecting permissive signal lamp LG or disconnecting dimmer LR.The corresponding feedback signal of window discriminator will be to the fault of computer system circular appearance.
When the S0/1 welding of regulating control contact in Fig. 1 during unshowned position, the position that this position arrives when being its connection permissive signal lamp, though then after disconnecting the permissive signal lamp, can light dimmer, but do not have corresponding monitor signal, this is because contact S0/1 is connected across the event in measuring resistor Rx two ends.If regulating control contact S0/2 welding unshowned position in Fig. 1, then the permissive signal demonstration still is switched on, rather than the stop signal demonstration is switched on.The fault that one corresponding alerting signal occurs to the computer system circular, and signal is sent in prevention.
In fact, identical to the breakdown signal of computer system transmission with the signal that when connecting the permissive signal lamp, sends not long ago to the heart yearn exposure test of feeder line that leads to this signal lamp and the circuit that is positioned at other current potential, promptly send a status signals of not wishing to occur in real time to computer system.The status signals that produces when this status signals and the switch position working properly has tangible difference.
Useful mode is to distribute to the current consumer that the computer system of controlling only has limited amount.So just can to current consumer and/or the switch member relevant with control and monitoring process be carried out periodically or incident control ground carries out functional check.Computer system is by reading in the periodicity of monitor signal and judging, identifies each conversion normal or mal whether among the alarm condition figure.By at first one pole and then just bipolar connection, according to being added in the current potential on given situation that leads on the current consumer feeder line, the regulating control closure in the current consumer connected loop to current consumer.Therefore can monitor this, and therefore start the possibility that these regulating controls is adopted common fully signal relay or contactless switch.
Monitor that break contact (machinery or electronics) the another kind of scheme of the switch position is the electrical hookup of electric power loop and monitoring circuit.Make contact is when the switch position of mistake, and do not wish that the voltage that occurs will receive on the annunciator that monitors this moment, does not wish that wherein will there be fault in the signal(l)ing condition that occurs to the computing machine circular.Fig. 2 illustrates this embodiment of the present invention; What relate to is the application of the present invention in switch, and this switch is powered by four heart yearns by a source of AC in known manner.Every heart yearn comprises derailing switch H11/1, H21/1, H12/1 or a H22/1, and this derailing switch is the contact of general purpose control relay H11, H21, H12, H22.Per two these control relays are cascaded, and switch on and off jointly.Connection is that by the trusted computer system of controlling and monitoring one or another computer access are realized; Disconnection realizes by a running current monitoring device LU this monitoring device can detect whether arrive the final position of pulling track switch, and interrupts the electric power loop of series connected control relay respectively when identifying the final position of pulling track switch.Control relay should make the electric power loop of switch WA motor coil W1 to W3 be subjected to be controlled by the control relay of different computer access operations by derailing switch all the time to the distribution of two computer access.Switch is when the final position of described track switch, and series connected coil W1 and W3 only connect by derailing switch H11/1 and H21/1, and coil W2 only connects by derailing switch H12/1 and H22/1; By different computer access attached separately control relay is controlled.The phase voltage of link is added on coil W1 and W3 or W3 and the W2 when switch moves.Two control current loop stream are through derailing switch H12/1 and H21/1 or H11/1 and H21/1; Attached control relay is assigned to different computer access.When switch arrives its new final position of pulling track switch, but contact-actuating is not as yet during changing-over, before motor coil is disconnected after contact-actuating is connected, by derailing switch H11/1 and H21/1 to motor coil W2 and W3 making alive, and by derailing switch H12/1 and H21/1 to coil W1 making alive.The disconnection of control relay realizes that by running current monitoring device LU this monitoring device does not have stream by contact-actuating and connects.Even also realize that by derailing switch to the drive coil feed, these derailing switches are controlled by different computer access at revolving process.
If when connecting switch, one or more derailing switches can not be closed, then switch or can not move or need operation unallowable long-time excessively.Both of these case is identified by annunciator, and circular also will be illustrated below annunciator to computer system.If one or more derailing switches do not disconnect when disconnecting switch, then annunciator identifies this equally, and circular is given computer system.To describe in detail its mode of action below.
Two annunciator M1 and M2 are used to monitor switch, and therefore are used for outdated disconnection of Direct Recognition or closed derailing switch.These two annunciators are designed to op amp, and are used for sending status signals to two computer access.Each annunciator can send two different signals according to the input current potential that flows to it, and wherein as first, and issue in the warning telegram MK1 or MK2 of the computer access of attaching troops to a unit as second insertion by another signal with a signal for annunciator.Two annunciators are by dedicated line one pole ground connection.Its signal input part is connected with two heart yearns that lead to switch by moving bridge contact B5, B6, B1.Two heart yearns that lead to switch are connected with the mouth that carries out control of Electric potentials of two direct voltage source U3, U4 by moving bridge contact B3, B4 in addition, wherein a heart yearn is connected with the positive pole of voltage source U3, and another root heart yearn is connected with the negative pole of voltage source U4.Other contact of two direct voltage sources is by dedicated line ground connection.The current potential that is provided by two direct voltage source U3, U4 by contact-actuating AK1 to AK4 is as monitoring that current potential is added to respectively on one or another annunciator M1, the M2.When switch when pulling the final position of track switch, positive potential is added in the signal input part of annunciator M1, and negative potential is added in the signal input part of annunciator M2.When switch was pulled the final position of logical trouble at another, negative potential was added in the signal input part of annunciator M1, and positive potential is added in the signal input part of annunciator M2.At the switch run duration, computing machine is not judged the alerting signal of being sent by annunciator M1, M2.The computer system of running current monitoring device LU contains corresponding status signal for this reason, and this status signal for example can be inserted on the warning telegram MK1, the MK2 that flow to two computer access the 3rd.But also can annunciator be transferred on the inoperative position, and prevent from status signal to be carried out analysis and judgement by the output signal of running current monitoring device at the switch run duration with the method.
If at this moment break down with drive coil electric power loop bonded assembly derailing switch owing to one or more, when when switch is disconnected, for example remaining closed, then superpose with the supervision current potential that flows to annunciator at the control voltage that inserts on the relevant controlling heart yearn by the derailing switch that lost efficacy on the annunciator at least owing to welding.Therefore annunciator does not then have output signal at mouth.This situation will be regarded as fault by the computer system that the warning telegram is judged.
If one or more regulating controls are not by the normal circumstances closure when connecting switch, for example the contact owing to them is fused on dead position, then the running current monitoring device also can be transferred to inoperative position with annunciator for after the maxim of switch operating provisions, and circular is given computer system.Owing to there not be the alerting signal of expecting, thereby computer system identifies and has fault.
Therefore can identify the switching function fault that may occur reliably two switch position.Given this, with regard to switch control, at this moment just can switch on and off this switch, and can not adopt the signal relay of the costliness of always for this reason using so far by control relay.Also can adopt electronic switch spare to substitute control relay, power circuit is carried out break-make control, this is because computer system equally also can identify its functional fault.
If the voltage of the supervision current potential of the control and regulation voltage of current consumer and derivation all on earth potential, then can identify the ground connection of current consumer reliably by the short circuit that monitors current potential.
