Description
Technical Field
The invention belongs to the field of railway signals, and particularly relates to a time sequence-based intelligent diagnosis method for turnout operation and maintenance of a computer interlocking system.
Background
The computer interlocking system is a signal device for controlling the turnout action, the signal machine state and the section state, indicating the running operation and ensuring the running operation safety, and has the core function of handling the operation of receiving and dispatching vehicles. The operation of receiving and dispatching trains needs to be completed firstly, the turnout is rotated in place, the access is locked, the signal can be opened, and the signal indicates that the train operates according to the specified speed and the driving permission. The turnout, a signal machine and a track circuit are called three major pieces of signal outdoor equipment together. The turnout is a turnout which is generally adopted on a state railway and has a positioning state (Normal Position) and a Reverse Position state (Reverse Position).
For controlling outdoor turnouts, a conventional computer interlocking system combines two relays, namely a DCJ (Normal operating relay) relay and a FCJ (Reverse operating relay) relay, with a turnout internal circuit part, and acquires a positioning state representation (DBJ) and a flip state representation (FBJ) of the turnout internal circuit part to realize the control of the turnout. The internal circuit part of the turnout operates according to the states of the DCJ and the FCJ, the required operating current is controlled to be output to a motor of the turnout switch machine, after the motor rotates to pull the turnout to rotate and be tightly attached, a display relay in the internal circuit of the turnout is sucked up, the computer is interlocked to stop outputting, power supply to the electromechanical machine of the turnout switch is stopped, and the turnout operation is completed.
In order to improve the safety of the system, in recent years, the computer interlocking system increases output and acquisition conditions at an interface part, firstly, the two indicating relays are proved to be in a falling state by a mode of indicating the Normal position and indicating the rear contact of the relay in series connection for acquisition by the Reverse position, and the condition is used for preventing the risk of 'false indication' caused by the fact that the acquisition mixed line is indicated when the turnout is not indicated; and secondly, controlling the turnout action, besides outputting DCJ/FCJ, outputting a 3 rd relay in an auxiliary mode, generally called YCJ or SFJ, and completing one operation by using two outputs. The two methods based on hardware output redundancy and collection redundancy reduce the risk of combining computer interlocking and switch internal circuits to a certain extent.
Nevertheless, when the relay is blocked, the protection condition of the rear contact of the relay is failed, and other multiple faults are indicated, if the actual turnout is four-way, false indication still occurs, and when the protection condition of the locking protection relay is failed, the mixed line of the output circuit still occurs turnout false operation. Thus, security risks remain. Only if the problems are found and judged in advance in the operation and maintenance of the equipment, corresponding safety protection is carried out, and the equipment is overhauled in time, so that the risk can be thoroughly avoided. However, at present, there is a technical gap in intelligent diagnosis of turnout operation and maintenance.

Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a time sequence-based intelligent diagnosis method for turnout operation and maintenance of a computer interlocking system, which is characterized in that according to the time sequence of normal turnout conversion, intelligent diagnosis is divided into two stages, namely conversion time and conversion completion time; as shown in fig. 1:
when the turnout is switched, whether an auxiliary operating relay fails or not is judged; if not, continuously judging whether the turnout position state shows no change during conversion; if not, continuously judging whether the rear contact state representation represented by the positioning and reverse state cannot be acquired; if the auxiliary operating relay or the rear contact state represented by the positioning and reverse state indicates that the acquisition cannot be carried out, a prompt is sent to a display interface; if the position state of the turnout during conversion shows that the turnout is not changed, setting the turnout in a closed state;
after the conversion is finished, the collected new turnout position state is represented, and at the moment, whether the conversion time is smaller than a preset value is judged; if yes, judging as false representation, and setting the turnout position state representation as no representation; if not, judging whether the operation intention of the conversion is consistent with the representation of the new turnout position state or not; if not, the turnout position status representation is set as a none representation.
The method further comprises the following steps: the method of how to remove the false representation after determining the switch as the false representation will be described later.
In the embodiment of the invention, the computer interlocking system realizes the switching control of the turnout by driving the positioning control relay (DCJ) or the reversal control relay (FCJ) and the auxiliary control relay (SFJ), and collects the positioning state representation (DBJ), the reversal state representation (FBJ) and the rear contact (DFH) state representation of the positioning and reversal state representation in real time.
The computer interlock is combined with the turnout through an internal control circuit to control the action of the turnout and acquire the representation information to judge the position of the outdoor turnout. And the computer drives DCJ, FCJ and SFJ in an interlocking manner and acquires three condition information of DBJ, FBJ and DFH. The computer interlock drives the DCJ and the switch will rotate to the Normal position. The computer interlocks to output FCJ and the switch will rotate to the Reverse position. In order to prevent the false operation of the turnout caused by the mixed output cables of the DCJ and the FCJ, the DCJ/FCJ is output, and simultaneously, one SFJ is output, and the joint condition (DFH) of the SFJ and the DCJ/FCJ is used as the condition of the turnout operation. And DBJ is Normal indicating information of the turnout, FBJ is Reverse indicating information of the turnout, and the falling condition DFH of one DBJ and one FBJ is collected to be used as the indicating condition of the turnout in order to prevent misjudgment when the DBJ/FBJ indicates cable mixing.
In the embodiment of the invention, the time sequence of the turnout normal conversion is divided into six time sequences of current position state representation, turnout operation control, turnout conversion starting, position state representation in the conversion process, position state representation after returning conversion and output stopping, and the six time sequences are sequentially recorded as time sequences 1-6.
Taking the example of the turnout turning from the Normal position to the Reverse position, the operation sequence of the turnout is shown in table 1.
TABLE 1 input and output information action sequence when rotating from Normal position to Reverse position
The above sequence is the normal turning process of the turnout, and other action sequences are all unexpected. There is a safety risk in performing a driving operation under an unexpected switch action or state. The first risk situation is that the switch still runs the train when in four switches (without a close position), and in severe cases, the train may fall off the track or even turn over. In the four-opening of the switch, if the state returned by the internal circuit of the switch is represented by 'no representation', no risk exists, but if the state returned is represented by a side, the safety risk exists, and the representation is called 'false representation'. The second risk is a malfunction of the turnout after the approach is handled. After the approach is handled, the signal is opened, and if the train runs in the approach, the running safety is endangered if the false operation of the turnout occurs.
The intelligent diagnosis process during and after the turnout switch is completed and the method for eliminating false representation are described in detail below.
Firstly, intelligent diagnosis during turnout switching.
1. And monitoring whether an auxiliary operation relay (SFJ) is effective or not.
The purpose of setting SFJ is to prevent the false operation of switch caused by the mixed electricity of positioning operation relay/positioning reversal operation relay (DCJ/FCJ) cable driven by computer interlock, and two relays of SFJ and positioning operation relay/positioning reversal operation relay are used to operate switch. Then, if the SFJ is sucked up by mistake, the clamping control function is lost, and if the mixed power fault of the positioning control relay/the positioning reverse control relay cable occurs again, the turnout will malfunction. Therefore, it is very important to supervise the effectiveness of SFJ.
In the time sequence 2, the computer interlocking system realizes the switch from reverse position to positioning by driving a positioning control relay and an auxiliary control relay; or the switch of the turnout is switched from the positioning to the reverse position by driving the reverse position operating relay and the auxiliary operating relay; namely, the SFJ is connected in series into an internal circuit of the turnout as a condition for operating the turnout.
In the embodiment of the invention, the time sequence 2 is changed into two time sequences, the computer interlocking system drives the positioning operating relay or the reverse operating relay firstly, and drives the auxiliary operating relay after a period of time; if the turnout loses the position status representation in the period, judging that an auxiliary operating relay fails and sending a prompt to a display interface; otherwise, the operation relay is judged to be effective.
The principle is that the positioning operation relay/the positioning reversal operation relay is already output, but the SFJ is not output at the time, and at the moment, an internal circuit of the turnout should not rotate; if the switch is not indicated, the switch is judged to be lack of the SFJ checking condition in the internal circuit of the switch, and the SFJ failure is indicated. The time interval from the operation of the switch to the loss of indication of the switch is generally about 1.5 seconds after the test, so the SFJ is determined as the output starting 2 seconds after the positioning operation relay/the reversal operation relay. The supervision and inspection can effectively prevent the occurrence of errors such as connection sealing and the like, and particularly can play a role in supervision and inspection of construction wiring in the engineering implementation stage. For example, where the switch is steered from the Normal position to the Reverse position, FIG. 2 is a diagnostic logic diagram for monitoring whether SFJ is active.
2. And monitoring whether the position state shows normal or not when the turnout rotation is started.
Normally, the point position status indication should be changed correspondingly from sequence 2 to sequence 3, which includes: changing the positioning state representation into a reversed state representation or changing the reversed state representation into the positioning state representation; if the switch position state shows that the change does not occur after a certain time, the switch is set to be in a closed state.
As can be seen in the example shown in table 1, when the switch starts to turn, from the time sequence 2 to the time sequence 3, the positioning state representation (DBJ) of the switch indicates that the state value should be changed from "1" to "0". When the representation of the original position is still unchanged after the starting time of the turnout is exceeded, the turnout can not be operated in place at the moment and is actually in a quarto state that the corresponding side represents that the turnout can not come back, and the indoor representation is false; the second case is a case where output or operation cannot be performed due to a circuit failure. In field use, the reason that the original representation of the turnout is still is obviously that the second situation is more, but the first situation has safety risk, and the two situations can not be effectively distinguished through the existing information state.
The invention carries out safety protection processing when the representation of the original position is still unchanged after the turnout starting time is exceeded. Namely, the turnout is automatically set to be in a closed state (the closed state of the turnout is a state of forbidding to arrange a route therethrough), and clear alarm information is given at the same time to prompt an operator to confirm and check. And after the user confirms that no risk exists, the closing of the turnout is cancelled. The supervisory logic diagram in this case is shown in fig. 3, and the specific times involved in fig. 3 are by way of example only.
3. The rear contact state represented by the supervised positioning and flip state indicates whether acquisition is unavailable.
Under normal conditions, when the time sequence is from 3 to 4, the position state of the turnout begins to change, and the computer interlocking system acquires the rear contact state representation represented by the positioning and reverse state; and if the rear contact point state representation represented by the positioning and reverse state is not acquired within the specified time, sending a prompt to a display interface.
The purpose of the back contact (DFH) for locating and flip state indication is to prevent the outdoor switch four and computer interlock from "false indication" due to mixed line failure of DBJ/FBJ. The principle is that DFH is collected when turnout is not oriented and in reverse position (DBJ, FBJ fall), and the state value is '1'. However, if the DFH is disconnected, the control effect on the turnout collection part is lost, and if the DBJ/FBJ indication information mixed line fault occurs, the turnout cannot be found out if the 'false indication' occurs. Therefore, it is very important to supervise the DFH status effectively.
As can be seen from the example shown in table 1, during the turnout rotation, from time sequence 3 to time sequence 4, the DFH changes from "0" to "1" during the turnout rotation and changes to "0" after the rotation is finished, so that the effectiveness thereof can be analyzed from the turnout rotation process and can be only analyzed at this time. After the switch is turned on, the position indication information will become "0". When the turnout is lost and represents for 2 seconds, if the DFH representation cannot be acquired, the DFH is judged to be failed, and a prompt of 'DFH state failure' is given on an operation display interface. The diagnostic logic diagram in this case is shown in fig. 4, and the specific times involved in fig. 4 are by way of example only.
The method monitors the state of the DFH by utilizing the output and acquisition change of the turnout from the time sequence 3 to the time sequence 4, gives clear early warning and plays an important role in reminding maintenance of electric service maintenance personnel.
And II, intelligently diagnosing after turnout conversion is finished.
1. And monitoring the reasonability of the turnout rotation completion time.
The outdoor turnout needs a certain time to complete the rotation. When the actual return of the switch indicates a time significantly less than the turn time of the switch, this should be unusual, possibly due to the switch-off of the outdoor switch equipment and a short connection somewhere within the switch. If the outdoor switch equipment is separated from the indoor, then the indoor false indication will mislead the operator and bring risks to the vehicle.
Starting from the time sequence 2 to the time sequence 5 when the turnout is operated, if the information return time after the turnout is rotated is obviously shorter than the rotation time of the turnout, if the 'false indication' occurs, the turnout is set to be in a safe state without indication.
Because the turnout is of various types and the rotation time parameters are inconsistent, a uniform time parameter is selected with certain difficulty. However, it is certain that the turnout requires time to turn, and it is impossible to turn into place immediately after operation. And when the internal circuit of the turnout is in short circuit connection at a certain position, the turnout is immediately turned to the right position.
Therefore, the invention judges if the position of the turnout is directly rotated, and sends out the prompt information according to the position state representation before and after conversion. If the positioning is carried out by reverse steering, prompting the reverse direct reverse positioning; if the positioning is turned to the reverse position, prompting that the positioning is directly reversed to the reverse position;
for example, turning from reverse to orientation, the logic diagram of the diagnostic process is shown in FIG. 5. The turnout is indicated to be positioned in the Reverse position at the moment, and the turnout is necessarily indicated to the operator to carry out necessary prompt, such as prompt of 'directly reversing to Normal by Reverse'.
The method utilizes the action time sequence of the turnout, controls the action time problem which is possibly generated from the time sequence 2 to the time sequence 5, judges the reasonability of the rotation time, gives out a clear early warning prompt and plays an important role in preventing false representation.
2. Supervising the correspondence of the maneuver attempt with the location state representation.
The intelligent diagnosis of the switch rotation to the position needs to consider the consistency of the manipulation intention and the representation. If the collected new turnout position state is not consistent with the operation intention of the current conversion and the current conversion reaches the set time, the situation that the current conversion is not in accordance with the expectation of operation is shown, the collected new turnout position state is not adopted for showing, and the turnout position state is set to be in a safe state without showing; and if the collected new turnout position state is not consistent with the operation intention of the current conversion and the time used for the current conversion is still within the set time, continuing to convert according to the control turnout until the expected turnout position state is collected or the time is out.
As can be seen in the example shown in table 1, from time sequence 1 to time sequence 6, the switch is operated in the reverse position, and at time sequence 5, the reverse position representation should be returned. However, if a Normal indication is returned at time sequence 5, an unexpected event should have occurred. Because the longest output time for operating the turnout is 30 seconds, the turnout can be processed within 30 seconds and outside 30 seconds respectively. If the above occurs within 30 seconds, to improve the usability, the FCJ and the SFJ are continuously output, and the switch is continuously operated towards the reverse position until the switch returns to the reverse position to indicate or the output is stopped until the time is out. If the representation is returned in more than 30 seconds, if the representation is returned as a flip state representation, the representation information can be adopted according to the expectation of the manipulation; if the return indication is a location status indication, which is not in accordance with the expectation of the maneuver, the indication information may be excluded and the no-indication safe state may be maintained.
The method can protect the false representation of the turnout to a certain extent by using the diagnosis method for representing consistency of the operation intention and the return indication in the whole turnout rotation process. For the example of controlling the switch to reverse, the logic for its diagnosis is shown in fig. 6.
And thirdly, after the turnout is diagnosed as 'false representation', removing the 'false representation'.
By combining the above analysis, the following three conditions show that false representation occurs, and at the moment, the turnout position representation is set to be a safe state without representation, and then the false representation is removed through a subsequent mode; in the first case, when the switch simultaneously appears the positioning state representation and the inversion state representation; in the second case: the conversion time is less than a preset value; in the third case: the operation intention of this transition does not correspond to the new switch position state representation.
When the turnout is not shown, the operator can operate the turnout certainly. In the method of releasing the "false representation", the methods of the above three cases are similar, i.e., all released by manipulating the switch. Taking the first case as an example, the principle is as follows: even if the 'false indication' faults of the two indications are removed, the indication of the turnout is not allowed to be directly confirmed in consideration of equipment safety, and the indication needs to be confirmed after the sequence 1-6 is finished again according to the operation of the turnout. That is, if only one switch position state represents after the switch is operated, the normal switch position state representation can be recovered by operating the switch in the opposite direction; if two switch position state representations still exist, the switch is operated for many times, if only one and the same switch position state representation is returned, the fault is relieved, and the returned switch position state representation is determined to be effective.
The method comprises the following specific steps:
(1) if the system judges that the mixed turnout position status is repaired by collecting information, namely only one turnout position status exists, if an operator operates the turnout in the opposite direction, the turnout position status can be restored after the turnout is turned to the right position and returns to the corresponding turnout position status.
(2) If two pieces of representation information still exist, even after the turnout is operated, the representation cannot be identified because the turnout rotates to one side of the mixed line, and the outdoor turnout does not necessarily rotate in place; operating the switch in the opposite direction will return to the two representations.
The processing logic is explained in detail, as shown in fig. 7, by taking as an example the case where the switch is mixed with the toggle state representation false representation when the switch is represented in the locating state. When the turnout is positioned, the DBJ and the FBJ are both '1' due to mixed inverted state representation, the mixed fault of the information is judged to occur, the turnout position state representation logic state is set to '0', and the fault state is recorded. When the switch is operated to the reverse position through the switch, the reverse position state representation information is '1', the positioning state is '0', and the DFH is '0', the positioning and reverse position state representation is compared with the previous time, the mixed line fault of the DBJ, FBJ and DFH before shows that the mixed line fault cannot be immediately used as a valid representation, the 'please operate again and confirm', and the switch representation logic state is '0'. After the positioning operation is carried out again, if the positioning state representation is returned and the unique state representation is returned twice, the fault can be explained to be relieved, and then the positioning state representation is determined to be effective. If the positioning and the inversion state representation is still returned, the 'false representation' still exists, and the electric service maintenance personnel is required to continuously search for the problem.
For the second case, operating the turnout again, and if the conversion time meets the requirement, determining that the returned turnout position state is effective;
for the third case, the switch is manipulated again, and if the returned switch position status indicates a match with the operation intention, the returned switch position status is deemed valid.
The method strictly judges the recovery processing of 'false representation', after the recovery of the card-controlled turnout 'false representation', the turnout must be operated, and the recovery representation is allowed only after the action is completed according to the time sequence 1 and the time sequence 6, so that the safety of the turnout and the interlocking is ensured.
In a word, the switch is the important risk source of railway signal, and this patent is through to computer interlocking system software to switch fortune dimension in-process intelligent diagnosis and security defense, and the security risk that in time discovers the existence can ensure the action of switch and express safety, prevents and controls, promotes signal equipment quality to the security risk and plays important role.

normally, the point position status indication should be changed correspondingly from sequence 2 to sequence 3, which includes: changing the positioning state representation into a reversed state representation or changing the reversed state representation into the positioning state representation;
if the switch position state shows that the change does not occur after a certain time, the switch is set to be in a closed state.
4. The intelligent diagnosis method for the switch operation and maintenance of the computer interlocking system based on the time sequence according to claim 1,
under normal conditions, when the time sequence is from 3 to 4, the position state of the turnout begins to change, and the computer interlocking system acquires the rear contact state representation represented by the positioning and reverse state;
and if the rear contact point state representation represented by the positioning and reverse state is not acquired within the specified time, sending a prompt to a display interface.
5. The intelligent diagnosis method for the switch operation and maintenance of the computer interlocking system based on the time sequence according to claim 1,
if the position state after the turnout is rotated is smaller than the rotation time of the turnout from the time sequence 2 to the time sequence 5, judging that the turnout is false, and setting the turnout position state representation to be a safe state without representation;
the reason for the situation is that a short circuit at a certain position of the internal circuit of the turnout is communicated, and at the moment, prompt information is sent according to the position state representation before and after conversion; if the positioning is carried out by reverse steering, prompting the reverse direct reverse positioning; if the positioning direction is reversed, the positioning direction is prompted to be reversed directly.
6. The intelligent diagnosis method for the switch operation and maintenance of the computer interlocking system based on the time sequence according to claim 1,
if the collected new turnout position state is not consistent with the operation intention of the current conversion and the current conversion reaches the set time, the situation that the current conversion is not in accordance with the expectation of operation is shown, the collected new turnout position state is not adopted for showing, and the turnout position state is set to be in a safe state without showing;
and if the collected new turnout position state is not consistent with the operation intention of the current conversion and the time used for the current conversion is still within the set time, continuing to convert according to the control turnout until the expected turnout position state is collected or the time is out.
7. The intelligent diagnosis method for the turnout operation and maintenance of the computer interlocking system based on the time sequence according to claim 1, characterized by further comprising the following steps:
when any one of the following conditions occurs, the false representation is indicated, and at the moment, the turnout position representation is set to be a safe state without representation, and the false representation is released through a subsequent mode; in the first case, when the switch simultaneously appears the positioning state representation and the inversion state representation; in the second case: the conversion time is less than a preset value; in the third case: the operation intention of the conversion does not accord with the new turnout position state representation;
for the first case, the mixed turnout position status is judged to be repaired through the collected information, namely only one turnout position status is shown, and the normal turnout position status can be recovered by operating the turnout in the opposite direction; if two turnout position states are still represented, the turnout needs to be operated for many times, if only one turnout position state representation is returned, the fault is relieved, and the returned turnout position state representation is determined to be effective;
for the second case, operating the turnout again, and if the conversion time meets the requirement, determining that the returned turnout position state is effective;
for the third case, the switch is manipulated again, and if the returned switch position status indicates a match with the operation intention, the returned switch position status is deemed valid.
