As shown in fig. 1, a flowchart of a method for automatically generating computer interlocking data based on a yard-shaped structure according to an embodiment of the present invention mainly includes the following steps:

step 1, analyzing the acquired station yard blueprint, gradually prompting and navigating the original information provided by the blueprint in a man-machine conversation interactive mode, and converting the original information into a data file with a uniform format and uniform coding.

The preferred embodiment of this step is as follows:

the blueprint is the original data provided by the design institute, such as signal equipment plan, signal display relation, interlocking table, etc., which is the basis for the interlocking software. In the reading stage, after the blueprints provided by a design institute are analyzed, the original information provided by the blueprints is gradually prompted and input in a man-machine conversation interaction mode, and the blueprints are converted into data files with uniform formats and uniform codes.

based on VBA auxiliary development tool, original information provided by a blueprint is converted into uniformly coded data, and extraction of formatted information also comprises lighting circuits, alarm and indication lamp information, rail power failure range, signal display relation, proximity locking, passenger special information, automatic blocking, field connection, protection turnout, scattered special, peak pushing, sliding and the like, wherein the alarm and indication lamp information specifically comprises alarm, early warning, indication lamps, voice prompt, signal repeater and the like.

And 2, performing graphical modeling on various objects by adopting an object-oriented method, extracting the geometric characteristics of each object, generating the link relation of each object by combining interlocking logic, and converting the geometric characteristics of the objects into the interlocking characteristics of the objects.

The preferred embodiment of this step is as follows:

1) a graphical object is generated.

In the embodiment of the invention, a geometric model is established by drawing a station yard plan, and various railway signal objects are generated, which at least comprise: track objects, turnout objects, signal objects, turnout zone objects and the like; the above objects constitute the basic elements of the site map.

In the embodiment of the invention, the track object is in a line segment form, and an insulating joint divides a long line segment (track object) into a plurality of line segments; the signal object is composed of a circular area capable of displaying a lamp position, a rectangular button area and an insulating joint on a graph, coordinates of the middle point of the segment of the insulating joint are point characteristics of the signal, and the middle point of the segment of the insulating joint of the signal is intersected with a track to form the signal object.

The above objects are all terms of railway signals, and are short line segments perpendicular to the line in the graph, taking an insulating section as an example. As with the example yard graph of FIG. 3, the line segment from S1JG to IIG is a track object that intersects 2/4, 6/8, 10/12 track objects to form a switch; it is divided by the insulation joints of S, D6 and XII three signal devices and the insulation joint between S1JG and S2JG to form the turnout-free sections of S1JG, S2JG and IIG.

In the embodiment of the invention, the generation of the turnout object comprises two stages of preprocessing and characteristic generation. As shown in fig. 4, in the preprocessing, all long line segments of the total station are traversed, intersection points with other long line segments and insulating joints are calculated, the start end and the end point are recorded in an array arr1, points in arr1 are sorted according to coordinates, a central point and two side points are considered in groups from the start end, and an object which can be a switch point is generated, and the object records the central point and the points surrounded by the two sides. As shown in fig. 5, for an object that may become a switch, first, the number of surrounding points is determined, and if the number is less than 3, the object directly exits, that is, the switch cannot be formed; if not less than 3, calculating the angle formed by the connecting lines of the central point and the surrounding points and sequencing. Two sides adjacent to each other and forming an acute angle are the two sides behind the turnout of the turnout; the two points after the fork are characteristic points; in the array of the surrounding points, except the point after the fork, the rest are the points before the fork; and determining the positioning and the reverse positioning of the turnout according to the positioning points selected by the drawing personnel.

The turnout-free section object is a line segment formed by connecting a left end point and a right end point in geometry and represents turnout-free, station track, end line, station connection section, semi-automatic port, self-closing block section and field connection section on the interlock; although the interlocking properties of the above parts are different, geometrically, they can be regarded as abstract, non-branching sections, that is, segments formed by connecting left and right end points, wherein the left and right end points are intermediaries for connecting with other objects.

2) Geometric features of the object are extracted.

Abstracting the geometric characteristics of the objects, on one hand, in order to form the link relation of the objects in the interlocking logic (the link relation is not only the basis of the operation of the interlocking software, but also the necessary condition for generating the interlocking target data); on the other hand, the geometric characteristics are converted into the object instance slot attributes, which are the basis for establishing rules in the subsequent steps to carry out reasoning and generate target data.

Changes in the yard graph are primarily caused by switches and, therefore, primarily describe the geometric characteristics of the switch objects.

Judging a positioning straight direction or an anti-positioning straight direction according to the positioning point of the turnout object, the turnout center point and the included angle of the straight line of the turnout center point and the turnout point; comparing the X coordinate of the positioning point with the X coordinate of the turnout center point, so as to judge the left and right directions of the turnout; counting the number of points around the considered fork point, and if the number is equal to 4, judging that the crossing line (the special term of the railway signal) is formed;

if the reverse position of the turnout object is also the turnout object, and the coordinate of the farthest point of the reverse position is equal to the coordinate of the farthest point of the turnout object, the current turnout object can be judged to be a double-acting turnout object, otherwise, the turnout object is a single-acting turnout object;

if the Y coordinate of the positioning point is larger than the Y coordinate of the anti-site, the positioning point is judged to be positioned above; if the coordinates of the reverse farthest point are superposed with the overrun insulation coordinates, and the position of the coordinate of the positioning farthest point has no overrun insulation joint, judging that the reverse position has overrun;

and dividing the turnout object into a plurality of graphic types and coding according to the included angle between a front turnout line segment formed by the center point of the turnout and the front turnout point and the horizontal line, and the characteristics of single and double movement types, the left and right directions, whether the turnout is positioned above and whether the turnout is positioned in the straight direction.

Those skilled in the art will appreciate that the X, Y coordinates refer to x-axis and y-axis coordinate values.

As shown in fig. 6, examples of various switch pattern types are given. Wherein, level indicates that the straight strand of the turnout is consistent with the horizontal direction; up denotes the upper side of the bent strand in the horizontal direction; down denotes the bent strand being below the horizontal; pie indicates that the bent strand is left-handed; na indicates that the bent strand is right-falling; dd indicates that the turnout is single-acting; sd indicates that the switch is double acting; slope indicates that the straight strand of the switch is inclined; left indicates that the turnout is open towards the left, namely an acute angle towards the left; right indicates that the switch is open to the right. Therefore, level-up-pie-dd indicates that the switch is horizontal up, left-falling, single-acting; level-down-na-sd indicates that the switch is horizontal down, right-falling and double-acting; slope-left-na-dd indicates that the switch is inclined to the left, pressed and moved singly; slope-right-pie-sd indicates that the switch is tilted to the right, left-falling, double-acting.

The central point of the insulated node of the signal object is the geometrical characteristic point of the signal, and the left and right end points of the turnout-free section object are the geometrical characteristic points of the turnout-free section object.

In the embodiment of the invention, the extracted geometric features of various objects are converted into interlocking features of corresponding objects, and the groove attributes of corresponding facts or instances in the subsequent stage are formed.

3) And generating the link relation of each object by combining the geometric characteristics of the object and the properties of the object as interlocking equipment, namely a signal, a left chain and a right chain of a turnout section, a turnout front chain, a positioning chain and a reversal chain of the turnout. The link relation connects the objects, is used as the slot attribute of the objects, is an important basis of automatic matching operation, and participates in the inference operation of interlocking data generation.

The key to forming the link relation is the relationship between the geometric relation of the objects and the interlocked operational order. When a signal object is inspected, selecting objects on the left and right of an inspection point by taking the middle point of an insulation node of the signal as the inspection point, and determining the left and right chains of the signal object; when a turnout object is inspected, selecting a left object and a right object of three points by taking a turnout front point, a turnout rear positioning point and a turnout rear reversal point as inspection points respectively, and determining a turnout front chain, a positioning chain and a reversal chain of the turnout object; when the turnout-free section object is examined, the left end point and the right end point are respectively used as the examination points, the left object and the right object of the examination points are selected, and the left chain and the right chain of the turnout-free section object are determined.

As shown in fig. 7, the geometric feature points of the switch object, the traffic signal object, and the turnout-free section object are used as the basis for generating the link relationship; as previously described, the coordinates of the midpoint of the insulated nodal line segment are the point features of the signal machine model; geometrically, the turnout-free section is a line segment formed by connecting a left end point and a right end point, so that the left end point and the right end point without turnout are considered; and 4 points of the turnout center, the turnout front, the positioning and the reversal are taken as geometrical characteristic points of the turnout. The coordinates of the geometric feature points are compared with the coordinates of the feature points of other objects, so that an equipment object set passing through the investigation point can be obtained, and the left direction or the right direction of the object relative to the investigation point can be determined according to the left and right attributes of the object. In order to ensure that the signal object is arranged in a position critical to the point of interest, the adjacent position of the passing object is adjusted.

And 3, automatically identifying local features of the station yard according to the link relation of the objects, wherein the local features of the station yard mainly comprise a turnout section, a quadrangle and a route.

1) The turnout section is an area consisting of one or more groups of turnouts and insulating joints, and the section can be classified and coded according to the figure type of the turnout and the position of the insulating joint.

The type of the turnout section refers to defining a certain section type for the turnout according to the attributes of figure classification of the turnout in the section, whether insulation exists before and after the turnout, a chain before the turnout, positioning after the turnout, a reversed chain, the direction of the turnout and the like. In the embodiment of the invention, the type of the turnout section is used as one of the groove attributes of the turnout class object instance and the turnout section fact template. The method lays a foundation for subsequent data calculation of overrun and drive.

As shown in fig. 8, there are 3 sets of switches in the switch zones 4-10DG, and the switches are sorted by X coordinate, switch 1 is 6# switch, switch 2 is 4# switch, switch 3 is 10# switch, and all of the 3 sets of switches are cross-over type, so the 4-10DG zone type is defined as: z-3-1-2-level-up-cross-3-level-down-na-cross.

2) The quadrangle is a special figure to be considered when the route is selected, the quadrangle which is characterized by a pair of diagonal switches can be calculated through the traversal of the binary tree, and the quadrangle can be determined to be a parallelogram or a splay quadrangle (namely a trapezoid) by combining the figure characteristics of the diagonal switches. Specifically, the method comprises the following steps:

and each group of turnouts starts along the direction of a turnout point, traversal is carried out by using a binary tree algorithm, if the observed sub turnout is a forward turnout, traversal is carried out back from the forward turnout, and if an object is found to be the reverse bit of the observed sub turnout, a quadrangle is identified. And defining whether the quadrangle is a parallelogram or an 'eight' -shaped quadrangle according to the types of the initial turnout and the forward turnout. As shown in fig. 9, the switch is appointed to position the switch in the straight direction, when the switch is moved from right to left, the 8# switch is the opposite switch, the next object is D6, the 12# switch is the opposite switch, the inversion chain 14# is stacked, after the search in the positioning direction, the 14# switch is popped up, because the 14# is the forward switch, the switch is searched back, the switch is moved forward along the positioning chain D4 to the 6# opposite switch, the inversion chain is the starting point 8#, and a closed loop is formed. In the process, a pair of switches characterized by 8#, 14# is recorded, and the generated quadrilateral is of the type pxsbx _ zs, namely the type is a parallelogram.

3) The route is a section of route through which a train or a train passes, and is a section from a start signal to a signal or a station boundary and an end line which are in the same direction and have the same property in front on a station yard graph. All train routes and shunting routes of the station can be generated by the link relation of the objects and the traversing method.

Take the train route of fig. 3 as an example. Starting from the station signal S, searching from the left to the right direction can generate the receiving routes from S to 4G, S to 3G, S to IIG and from S to 1G; from the right to left direction, departure routes of X4-S, X3-S, XII-S, X1-S may be generated.

The routes generated by the station traversal may have more interlocking table requirements, and the invention selects relevant ways to form the required routes according to the situation: the method is characterized in that the initial terminal and the turnout position of all routes are exported by an interlocking table to form a file, the routes in the file are compared with the routes generated by traversing the station yard to find out the matched routes, and the matched routes are marked for subsequent conversion into route instances for reasoning. And the second mode is that when the interlocking table can not be exported, key turnouts (namely a pair of characteristic turnouts recorded by the quadrilateral object) passing through the route are interactively selected by manually clicking a start button, a change button and a terminal button on the graphical interface to determine the route according with the trend of the interlocking table.

And 4, designing a self-defined fact template and class structure by combining the interlocking characteristics, instantiating the fact template and class by using the data file with a uniform format and uniform coding, the acquired I/O table file and the station yard local characteristic identification result, and generating various fact and object instances required by the reasoning operation.

In the embodiment of the invention, the custom fact templates are divided into eight types according to functions: I/O conversion, customer specific interface, non-routing facts, signal display, yard characteristics, dispersion information, proximity locking, and general logging. Wherein:

the I/O conversion mainly comprises: the acquisition (I/O) fact template is driven. The slot attributes are: original I/O name, converted I/O name, collection or drive, cage number, plate internal serial number and station number. The rest of the slot attribute values are from the I/O table files provided by the design institute, except that the converted I/O name is the result of the subsequent rule reasoning. Instantiated called I/O facts, which record the relay information driven and collected from the design institute.

The special guest interface mainly comprises: recording a radio block center interface (RBC) route fact template and a CBI-TO-CBI fact template interlocking an inter-station interface. The slot attributes of the RBC route fact template are as follows: the starting point name, the starting point property, the end point name, the end point property and the like, wherein the slot attribute values of the facts come from an interface file (a file made by an RBC manufacturer), namely, the interface file is exported into a file with a uniform format by using a VBA development tool, and each route is instantiated and converted into a corresponding RBC route fact; the CBI-TO-CBI fact records all information received or sent by the interlocking inter-site interface, and is generated from a uniformly formatted and uniformly encoded data file (i.e., the slot attribute values are from a uniformly formatted and uniformly encoded data file). A fact called CBI-TO-CBI after instantiation.

The non-route fact template mainly refers to non-route information, and the slot attribute of the template comprises the following steps: non-route starting end, non-route terminal, special attribute, all turnouts, turnout positions, opposite turnouts, a non-route locking relay driven by a departure place, a general rail relay driven by the departure place and the like. The non-route starting end, the non-route terminal and the special attribute come from data files with unified format and unified coding, the original design requirement is recorded, and if the non-route starting end and the special attribute are the non-route starting place, the special attribute has the starting place identification; all turnouts, the positions of the turnouts and the slot attribute values of opposite turnouts are intermediate results of the non-route rule; the drive logic for the departure relay (i.e., departure driven non-route locking relay, departure driven main rail relay) is part of the interlock data. After instantiation, the fact is called non-routing.

The signal display aspect mainly comprises: a signal display fact template, a departure gate-departure direction fact template, a terminal signal fact template for recording passing buttons and the like. After instantiation, the fact is called signal display fact, departure mouth-departure direction fact and the fact that terminal signals passing through the button are recorded. The signal display fact is generated by a data file with uniform format and uniform coding, and records the display and condition of the signal and the front signal. The departure mouth-departure direction fact is generated by a data file with a uniform format and uniform coding, records the departure mouth without a fork, the design direction of the departure mouth, the name of the outbound signal, the actual direction in the interlocking software and the like, and is a necessary condition for forming the outbound signal display data. The slot attributes of the terminal signal fact (called as the THROUGH fact for short) recorded THROUGH the button are as follows: passing through the starting end signal of the route, the starting end of the next route and the terminal button; the THROUGH fact mainly plays a role of recording data in generating the rule of the data of the passing route.

The fact template in the aspect of station yard characteristics mainly comprises: switch section fact templates, guard switch fact templates, etc. The slot attributes of the switch segment fact template include: all switches, interlocking section names, section types, switches 1, 2, 3 and 4 from left to right in the section, wherein the interlocking section names are interlocking data to be generated finally, the actual slot attribute values of the other switch sections are generated on the basis of identifying station local features in the step 3, and the actual slot attribute values play a role in mode matching in subsequent rules of overrun, driving and the like. The protection turnout fact template records the type of the protection turnout, the protection active turnout and the protection passive turnout, and is from a data file with a uniform format and uniform coding. The instancing is called switch section fact and guard switch fact.

The additional information mainly includes: a fact template indicating information package (SUB-gather) and each value (SUB-pack-every-member) of the package. The slot attributes representing the information packaging fact template include: sequentially packaging the acquired code bits and the formatted whole packaged value, and recording an intermediate result of reasoning by the two slot attributes; the fact template for each value packed has two slot attributes: one is an acquisition information expression, which is used for recording acquisition code bits of I/O and is derived from a data file with uniform format and uniform coding; the other is the coordinates of the package, recorded in the package, which is the intermediate result of the inference. After instantiation, the fact is referred to as the fact representing the information packaging fact and each value packaged.

The proximity lock fact template, referred to as proximity lock fact after instantiation, records mainly the semaphore name of the proximity lock, the type of the proximity lock, and the farthest section of the signal in the station near the extension, and is generated by a uniformly formatted and uniformly encoded data file.

The general record fact template is called general record facts after instantiation, mainly plays a role of an intermediate variable, records the results of intermediate reasoning, such as the fact that the number of relays for displaying outbound signals green and relays for displaying green and yellow (LJ \ LUJ) is recorded, and also records the fact that the positioning chain of the turnout at the upper left corner of the cross crossover is THROUGH.

In the embodiment of the invention, the self-defined class structure comprises: turnout class, signal class, route class, quadrilateral class, turnout-free section class and auxiliary object class; wherein:

the slot attributes of the switch class include: pattern type, insulation before the fork, insulation after the fork, whether the fork is positioned at the upper part, positioning chain, inversion chain, chain before the fork, whether the crossover line is crossed, direction, section type and the like. After instantiation, called switch instance, the section type is generated in step 3, and other attribute values are generated on the basis of the graph modeling of the switch object in step 2.

The signal classes are further classified into inbound signals, outbound signals and other signal classes (i.e., signals excluding inbound signals and outbound signals). The station-entering signal records the attributes of a front straight-direction route, a front lateral route, whether a button passes through or not, whether a positive line relay exists or not, a green-yellow signal relay, the driving of a signal relay and the like; the outbound signal class records the characteristics of a forward straight approach, a forward lateral approach, all departure ports, the total number of departure directions, the type of a lighting circuit and the like, in the attributes of the inbound and outbound signal class grooves, the forward straight approach and the forward lateral approach are derived from intermediate data close to locking data inference, and the attributes of the rest grooves are derived from data files with uniform formats and uniform codes. After instantiation, the signals are collectively called signal examples and are specifically subdivided into inbound signal examples, outbound signal examples and other signal examples.

The slot attributes of the route class are: all turnout names, all turnout positions, all straight turnouts, route characteristics, starting end signals, terminal signals, route properties, the starting end of the next route and the like, wherein the route characteristics can be all turnout straight directions, UUS (starting end signal double yellow flashing signal display) satisfaction and the like, and the starting end or terminal signals can be signals of an entering station, an exiting station or other signals in signal classes. The route property is used for distinguishing the train route and the shunting route. The attribute of the route characteristic slot of the route class is generated in the initial process of reasoning; other slot attributes are generated at step 3 local site identification. After instantiation, the route instance is called.

The slot attributes of the quadrilateral class are: the type of the quadrangle, the head turnout of the quadrangle, the diagonal turnout of the quadrangle, the left access, the right access and the like, the left access and the right access of the slot attribute of the quadrangle are generated in the middle inference process after the access instance exists, and the attribute values of the rest slots are derived from the local station identification in the step 3. And the instantiation is called quadrilateral instance.

The turnout sections can be divided into semi-automatic, automatic block, field connection, peak pushing, station connection and the like according to different interlocking properties. Wherein the slot attributes of the automatic occlusion class include: the other section points of the section, such as the receiving or departure gate, record the other passing signal controlled by the section, which is the receiving or departure gate in the normal condition. The semi-automatic type records the semi-automatic type, the station signal of the vehicle receiving port and the like. The field section type records the name of the present party signal, the name of the opposite party signal, the nature of the field section and the like. The push peak and station connection records the direction of the station signal machine and the direction of the vehicle receiving port. The common feature of semi-automatic, automatic block, field join, peak push, station join classes is that their associated drive acquisition information in the I/O table needs to be converted. The slot attributes of the unshorted section class are generated by uniformly formatted and uniformly encoded data files. The examples are collectively called as turnout-free section examples after instantiation, and are specifically subdivided into semi-automatic examples, automatic blocking examples, scenario-linked examples, peak pushing examples and station-linked examples.

The auxiliary object class mainly comprises: and generating a similar show-pack-condittI/On-one-con and a signal repeater packing condition class for alarming, early warning, indicating lamps and voice prompt packing conditions. The similar show-pack-conditI/On-one-con slot attribute: the type, the condition and the alarm time, and the type attribute records identifiers after alarm, early warning, indicating light and sound prompt classification; the condition attribute records the specific condition expression of the package, and the specific condition expression can be matched with each packaged value SUB-pack-even-member fact; the alarm time attribute records whether the relay is used for alarm when being sucked or dropped, so as to generate final alarm prompt data. The slot attributes of the signal repeater packing condition class are mainly various conditions for the repeater to light up. The slot attribute values of the class show-pack-condittI/On-one-con and the signal repeater packing condition class are derived from data files with uniform formats and uniform codes. After instantiation, the objects are collectively called as auxiliary object instances and are particularly subdivided into show-pack-consistent I/On-one-con instances for generating alarm, early warning, representing lamps and voice prompt packing conditions and packing condition class instances of signal repeater data.

Those skilled in the art can understand that the fact template and various slot attributes in the class structure are preset by the operator according to the actual situation, and the instantiation is to fill various information from the design institute into the corresponding slot attributes to obtain the corresponding facts and instances.

And 5, establishing a generation rule of the interlocking data by utilizing various facts and various examples, and automatically matching by adopting a forward chain reasoning method to generate the interlocking data.

The preferred embodiment of this step is as follows:

1) rules for I/O translation. And converting the original names of driving and collecting in the I/O facts into names required by interlocking software according to class object examples such as semi-automatic examples, outbound signal examples, automatic blocking examples, field union examples, peak pushing examples, station union examples and the like.

2) Guest specific interface class rules. According to slot attribute values such as a starting point name, a starting point property, an end point name and an end point property in RBC route facts, slot attribute values such as a receiving or departure gate in an automatic block instance and other interval points in an interval, an interval direction, an interval name and the like are automatically matched, and a wireless block center interface interlocking data file is formed; and secondly, automatically generating an interlocking data file of the inter-station interface according TO the CBI-TO-CBI fact, the turnout-free section instance, the route instance and the signal instance.

3) Non-route class rules. Forming data of a non-route initial terminal signal according to the attribute value of the non-route initial terminal and the non-route terminal slot of the non-route fact; acquiring all turnouts and opposite turnouts which are not passed by a route according to a shunting route example between a non-route starting end and a non-route terminal; generating data for cutting off the routing message according to the slot attribute value of the opposite turnout; automatically generating data of unlocking the non-route without checking the track relay according to the turnout passed by the non-route, the position slot where the turnout is located and the signal example adjacent to the turnout; and automatically generating driving relay data combined with the departure according to the value of the special attribute.

4) The rules of the signal display class include the display of inbound and outbound signals.

The train route is initialized firstly, and whether the route is all straight or not or whether UUS characteristics are met is calculated according to all turnout positions of the route instance. And automatically matching the route instance meeting the UUS characteristics with the signal display facts to generate UUS data of the route starting end signal.

There is an inbound signal through the route, and a terminal button through the route is to be found. Firstly, the starting end signal of the passing route is matched with the straight train route example in front, the terminal button of the passing route is found, then the matching of the starting end signal, the receiving route, the departure route and the related signal display facts is carried out, and the interlocking data of the passing route is generated. In this section, the route of receiving a car and the route of departure are examples of routes; the start and end of the route are the slot attribute values of the route instance.

Fig. 10 is a state transition diagram of a terminal button for seeking a pass-through route. Firstly, matching three conditions of an inbound signal passing THROUGH the starting end of a route, a straight train route taking the inbound signal as the starting end and no fact THROUGH, generating the fact THROUGH, and recording a starting end signal (; reasoning then, if there is a fact, THROUGH, it records the beginning of the next route (: if a plurality of straight train routes are connected in the middle, the system can automatically match the routes meeting the conditions and automatically record the starting end of the next straight train route; until the start of the next route is matched to null, the terminal button of the route (. Then, the fact THROUGH that the terminal button is not empty is checked, the matching of the starting end, the vehicle receiving route, the vehicle departure route and the related signal display facts is automatically carried out, and if the conditions are all satisfied, the data related to the passing route is generated.

The outbound signal automatically generates display relation data of the outbound signal by recording the number of LJ \ LUJ keywords in the general recording fact, the route instance of which the outbound signal is the starting end, the next route starting end of the route and the signal instance matched with the starting end. In the case where the outbound lighting circuit has two directions and the departure gate has more than two directions, the interlocking data of the outbound signal with respect to the departure gate having more than the lighting circuit requirement is generated by automatic matching based on the fact that the object instance of the outbound signal and the departure gate-departure direction.

5) Automatically identifying a particular local yard and automatically generating associated interlocking data, comprising:

the cross-over lines are common local station yard units, and the interlocking data is relatively fixed. The inference of the cross crossover starts from the top left switch, as shown in fig. 11, the positioning chain is recorded by using the general recording facts, the matching condition is forward until the top right switch is found, the attribute value of the recording fact slot is modified into the starting switch plus the bottom right switch, and the object modes of the two switches are matched to automatically generate cross crossover data.

The names of the turnout sections are key interlocking data, particularly in a large junction station, the names preset by the system and actual acquisition code bits are often inconsistent, and the names of the sections where the turnout is located can be automatically corrected by adopting an absolute value fuzzy matching method. Specifically, all switches of the switch section facts are matched with names in switch examples, and then the names of the sections where the switches are located are automatically corrected by adopting an absolute value fuzzy matching method according to the names of switch objects in a station yard graph and the names of the sections in a driving and acquisition table (I/O table); there are generally four cases:

in the first case, if a section has two switches G1 and C1, the section name is first tentatively given: g1-1 DG. Then, searching is carried out in the I/O fact set, if there are acquisition code bits in the form of "I _1_ G1DGH", for example, "I _" and "DGH" are removed, and then "_" is disassembled, if the two groups of obtained turnouts C1 and CG1 are in the sector, and the preassigned sector names G1-1DG and 1_ G1DG are compared to be unequal, the name 1_ G1DG in the I/O fact is directly taken as the corrected interlocking sector name.

Second, if a section has more than two sets of switches, e.g., C5, C7, the section name is first heuristically given: 5-7 DG. Then, searching in the I/O fact set, if the acquisition code bit in the form of "I _5_7DGH" is found, removing "I _" and "DGH", and then breaking up "_", if the two resulting sets of switches C5, C7 are both within a segment, and comparing the segment name of the I/O fact and the pre-assigned segment name 5-7DG to be equal, then the interlocking segment name in the modified segment fact is NOXuGai, indicating that no interlocking segment name needs to be modified.

In the third situation, more than two groups of turnouts are arranged in one section, in the I/O fact set, for the collection of possibly multi-turnout sections, the collected code bits are split to obtain a front turnout a and a rear turnout b; and (4) removing the letter C from all the turnouts in the turnout section, and then sequencing, wherein the smallest turnout is taken as C, and the largest turnout is taken as d. If the absolute values of a and c are less than or equal to 2 and a is less than or equal to c, and the absolute values of b and d are less than or equal to 2 and b is greater than or equal to d, then the block name in the I/O fact is taken as the interlocked block name.

In the fourth case, similar to the third case, the pick-and-place width guess has a range of 4, i.e. the absolute values of a and c and b and d are 4, to detect the switch in the segment, and when the switch falls into this range, the name of the segment is considered to be found. It should be noted that the first and second cases have the highest priority and are placed in the initialization control rule set, the third case has higher priority than the fourth case, and the control modules in the same level are distinguished by priority values.

As will be understood by those skilled in the art, absolute values represent how similar values are. For example, C23, C21 has an error of 23-21 in absolute value of 2.

6) And automatically generating driving data of the turnout according to the section type value in the turnout section fact and all turnouts in the section.

7) Rules for protecting switches. According to the protection turnout fact and the related turnout instance in the protection turnout fact, automatic matching is carried out, and the conventional protection data and the special protection data such as protection for the shunting small figure, protection for only the train route and the like are generated.

8) The alarm, early warning, indicating lamp, voice prompt and signal repeater belongs to the other scattered information; the type of information and the condition and time of alarming are recorded by generating a similar show-pack-condittI/On-one-con example which gives an alarm, gives an early warning, and indicates the packaging condition through a lamp and a sound; recording all I/O by representing information packaging facts; the condition data in the alarm, early warning, indicating light and sound prompt bitmap and the packed data are automatically calculated by combining the fact of each packed value, the position of the condition in the package and the content of the matched condition.

The early warning information and the alarm information are taken as an example for explanation. The formatted file is exported from step 1, and the contents included therein are as follows: BJXX _ BJ _ NAME, fuse alarm BJXX _ XINXINNAME, I _ RBJ BJXX _ BAOJING _ SHIJI:1, which respectively represent the content prompted by the upper computer, the acquisition code bit of the I/O table and the alarm time. Step 4, generating a show-pack-contiditI/On-one-con instance, which has a slot attribute type to record the type of the alarm information; the method comprises the steps of groove attribute condition, recording acquisition code bit share _ g of I/O, input [ I _ RBJ ], and alarm opportunity attribute. At the same time, the aforementioned step 4 also generates a SUB-pack-event-member fact, which is each value of the package, and it has a slot attribute expression, which is used to record the acquisition code bit share _ g.input [ I _ RBJ ] of the I/O, and the coordinate SUB-coordinate of the slot attribute packet, i.e. the position in the status packet, is in the form of: STSUB1, 4. At initialization of the system, the totally packed fact SUB-gather is generated, and a slot attribute of the totally packed fact SUB-gather is used for recording all the packed collection code bits in sequence, and the slot attribute all-number-pack is a formatted totally packed value.

In the system initialization stage, the expresssion slot of the SUB-pack-even-member and the member-one-by-one pattern of the SUB-gather are matched, and each collected code bit is written into the member-one-by-one slot of the SUB-gather; at the same time, the value of the slot attribute sub-coordinate is calculated. And then, in the next control stage, activating a rule matched by the expression slot of the SUB-pack-event-member fact and the condition attribute of the show-pack-conditional I/On-one-con instance, and combining the attributes such as the alarm opportunity and the like in the show-pack-conditional I/On-one-con instance to generate the final data required by the attribute box.

The signal repeater adopts the design of fixing the packing bits, and each signal repeater fixedly distributes one packet (16 bits), so the position of the packing condition in the packet does not need to be considered, and the lighting data of the repeater is easily deduced according to the packing condition slot attribute of the signal repeater example.

9) And (4) an overrun class rule. And automatically generating overrun interlocking data according to the slot attributes (the overrun position, the left and right directions, the positioning of the turnout, the graph type and the positioning reversal chain) of the turnout class object instance and the fact of the section.

As shown in fig. 12, there is an overrun between 1# and 3# switches, with 3#, 5#, 7#, and 13# switches in one sector. The overrun of the example is abstracted to be a general case, the No. 3 turnout is named as a right turnout, and the No. 1 turnout is named as a left turnout.

In the object instance for the right switch, the designed slot attribute (mynamerSwname) is its name; the slot attribute (ovirinsu-tu-locatI/On n) indicates that it is over-limited in location; the slot attribute (is-right left) indicates its direction to the left; the slot (normal-up true) representation is positioned above; the graphics classification swgraphics-type attribute contains level-down, which indicates that the graphics type is horizontal downward; the spacer chain (normal-linkrSwNlink) is a pattern-matching groove.

The fact that the right switch is in the switch segment, the condition of pattern matching is that it contains the multi-field slot value all-sw? rskname, whose segment type groove is (ovirinsu-sec-typersswsectp).

In the object example of the left switch, the designed slot (mynamerSwNlink) pattern matches the positional chain of the right switch; the slot attribute (ovirinsu-tu-locatI/On n) indicates that it is over-limited in location; the slot attribute (is-right right) indicates its direction to the right; the graphics classification swgraphics-type attribute contains level-up, which indicates that the graphics type is horizontal upward; name of right switch that locates chain (normal-linkrSwname) pattern matching? rskname.

The fact of the switch section where the left switch is located, the condition of pattern matching is that it contains a multi-field slot value all-sw? rsvnlink, i.e. the name of the left switch, and its segment type groove is (ovirinsu-sec-typeswsectp).

The right switch object, the fact of the switch section where the right switch is located, the object of the left switch, and the fact of the switch section where the left switch is located constitute object pattern matching.

From the above pattern matching, and additionally the type condition of the section, the data exceeding the limit can be inferred. If the left switch segment is of the type z-1-level-up-pie or z-1-slope-right-pie, i.e., contains only one set of switches, the overrun data for the right switch can be inferred as: "OINSU: point _ g ["? rsknlink "]. GJ | (2 ═ point _ g ["? rsknlink is the name of the left switch. If the type of the right turnout section is z-1-level-down-pie or z-2-1-level-down-pie-2-lean-pie-left, the overrun data of the left turnout can be deduced as follows: "OINSU: point _ g ["? rskname "]. GJ | (2 ═ point _ g [". If the type z-4-1-level-down-pie-2-level-down-pie-3-4-level-up-cross of the right switch segment, i.e., the type of 3-13DG shown in fig. 12, the overrun data of the left switch is: "OINSU: point _ g ["? -GJ | (2 ═ point _ g [ "? rskname is the name of the right switch,? rsw-2,? rsw-3,? rsw-4 are the names of switch 2, switch 3, and switch 4, respectively, in the switch segment facts.

10) And the interlocking data of the corresponding type is generated by inference according to the characteristics of the station yard and corresponding semi-automatic instances, field connection instances, station connection instances, automatic blocking instances and peak pushing instances.

As shown in fig. 13, SJG is the approach track of the semi-automatic port, the value of the inbound semaphore slot of the semi-automatic object instance is S, and at the time of station yard feature identification in step 2, the left chain of S, i.e., switch C2, is generated. Therefore, the semi-automatic instance is matched with the inbound signal instance to generate data of the first turnout in the semi-automatic inbound signal: "INSJ: point _ g [ C2]. SJ".

11) And (3) carrying out inference calculation on the approach locking data of the signal according to the inbound signal or outbound signal instance, the approach locking fact of the signal, the automatic blocking instance and the like.

And (3) calculating preferentially: intermediate reasoning data of the signal instance can be obtained from the slot attributes of the next route, the starting end of the next route (matching the name of the signal instance), the route characteristics (straight or curved), and the signal instance: a forward lateral approach and a forward straight approach.

As shown in fig. 14, the approach lock type of outbound signal XII is: GD-JC-ZB-CT-UUS. Outbound signal XII, preceded by a straight-ahead path XL to IIG, inbound signal XL being the beginning of the straight-ahead path ahead of the outbound signal, XL being preceded by an auto block, XL2 being preceded by an inbound path to IIG, all switches 18 being traversed and all lateral. There is an interlocking meter train route that starts with the outbound signal XII, which is either UUS-characterized or straight.

The above-described yard is abstracted to a general case. The object instances and facts required for automatic matching are as follows:

outbound signal instance, name attribute (mynamename) is a slot attribute that matches the name of the proximity lock fact; (right-advance-routes $? The length of zt-jl is 1, which indicates that only one section of the approaching straight route is available; (curve-advance-routes $; (right-or-leftfx) is the direction of the outbound signal; (right-linkc-rlink) is right strand; (left-linkc-llink) is the left strand.

Inbound signal instance, name attribute (mynamehsig), which matches the start of the straight-forward route; (no-drive-zxjnzxj), whether to drive ZXJ; (right-link) represents a right chain, (left-link) represents a left chain, and the right chain or the left chain is a name attribute used to match the self-occluding object.

Auto-block instance, name attribute (mynameznname),? zbname or equal to the left chain of the inbound signal? l-link, or equal to the right-hand chain of the inbound signal? r-link; the attribute (outta-all-sectI/Ons $.

Proximity lock facts, the signal name (signamesignname) sought for proximity lock, here matching the name of the outbound signal; type of proximity lock (jjsb-type GD-JC-ZB-CT-UUS); close to the farthest section of the self-closure from which the lock is to extend (sectI/Ons $.

One more test condition: there is any train route in the route set that starts with the outbound signal above, either UUS-characterized or straight.

The above object instances, facts, and automatic matching automatically generate proximity lock data for the yard, XII, as shown in fig. 14.

First, is the self-blocking slot attribute $ and the farthest segment sectI/Ons in the near-locking slot attribute station? wcselect i/Ons in combination, allows for calculation of out-of-station proximity lock-out data.

Then, according to the lateral access slot (curve-advance-routes $.

Finally, based on the direction of the inbound path, i.e., the outbound signal, data is generated that is close to lock: "GJJ: ((" | sigt _ G [ ".

12) And recording the routes passing through the left side and the right side of the parallelogram according to the quadrilateral examples and the route examples, and carrying out reasoning to generate interlocking data for cutting off the route selection message.

The rule solves the parallelogram routing conflict, and mainly comprises the following three aspects:

one is to generate intermediate data needed for reasoning. The method mainly comprises the steps of counting and recording the routes of trains passing through the left side and the right side of a parallelogram. The method is characterized in that type constraint is carried out through the attribute of a quadrilateral type sbxtype groove, matching is carried out through the attribute of a quadrilateral first turnout and all turnouts in a train route instance, routes which pass through the parallelogram first turnout in a train route set and meet position requirements can be picked out and stored in a left-bian-routes or right-bian-routes groove of the quadrilateral.

And secondly, cutting off the data of the routing message. The slot property of a quadrangle is designed, and a parallelogram of a lower left type is taken as an example. Type attribute: (sbxtype pxsbx _ zx); diagonal switches of the quadrilateral: (jl-dujiao-swfc 1); a right-hand route attribute (right-bian-routes $; left-hand route attribute: (left-bian-routes $. If there is no parallelogram with the same diagonal switch and the left hand path of the parallelogram is greater than zero, it can be inferred that the right lower chain of the diagonal switch should have data "BR: 4".

And thirdly, conditionally cutting off the data of the routing message. As shown in fig. 15, going through the first switch (; passing through a first switch (; combining the object patterns of the first switch and the diagonal switch, the automatic matching parallelogram is of a lower left type, and in case of needing conditional disconnection of the routing message, it can be inferred that the lower right chain of the diagonal switch should have data "CBR:4" ((point _ g [ "?qc 1" ]. O2SMES ═ 0x1003) | (point _ g [ "?qc 1" ]. O2SMES ═ 0x0003)) ".
