Technical Field

Background

In a rail transit signal system, a plurality of subsystems (such as a traffic dispatching command system, a central control system, a monitoring and maintenance system, a dispatcher maintenance terminal, an interlocking system control display machine and the like) are required to display a circuit plan. For the same station on the same line, the fact that different subsystems need to display the same station yard graph means that the same station yard graph is displayed; in the railway signal system, in the same interlocking station, the interlocking system, the CTC system and the microcomputer monitoring system need to display a station map of the same station; in a subway signal system, an interlocking system, a local ATS system, a central ATS system and an MSS system need to display the same station yard graph and the layout requirements of equipment are consistent.

In the whole rail transit signal system, different subsystems bear different train operation support functions, engineering data required by the operation of each subsystem is usually designed and completed independently by different teams, so that display terminals of different subsystems in the signal system need to repeatedly produce the same station yard drawing, and tools for producing, editing and checking station yard data are provided by different subsystems, which leads to the following problems: (1) The station yard data design tool provided by each subsystem is generally specific to each signal system and has no universality; because the data design of each subsystem station yard is greatly different in structure and mode, the function difference between systems can cause inconsistent station plane diagram display, and the user interface experience is not friendly. (2) The station yard graph needs to be drawn manually according to a station signal plane graph provided by a design institute, the drawing tool can only be a semi-automatic tool, the probability that errors are caused by operation can be reduced to a certain extent, but the drawing tool still depends on a large number of manual checks and tests, and manpower and time are consumed very much. (3) Because the station yard data is designed by different subsystems, the station yard data of the same station is repeatedly designed for many times, and the transplantation and repeated utilization rate of the data is low.

As shown in fig. 1 to 8, this embodiment provides an automatic generation method of a station yard graph, including: step S110, acquiring station yard data of a computer interlocking system; step S120, analyzing the station yard data of the computer interlocking system to obtain equipment information and an interlocking route table of the station yard; step S130, abstractly defining each device of the station yard as a single node, and acquiring a connection relation corresponding to the node according to the device information; step S140, corresponding to the position data of the node according to the interlocking route table and the equipment information; and step S150, generating a station yard graph according to the connection relation and the position data of the nodes.

It can be understood that the device information includes a name, a type, coordinates, an index number, an uplink connection relationship, and a downlink connection relationship of the device; and the types of equipment include semaphores, switches, insulation sections, crossover lines, sections, and checkpoints.

Specifically, in this embodiment, the computer interlock system is a key system for ensuring train driving safety in the rail transit signal system, and in the engineering design of the whole rail transit signal system, the computer interlock system is first opened and applied, that is, the data of the computer interlock system is first designed and produced; station yard data (namely computer interlocking system station yard data) in the interlocking data is a carrier and a reflected form for realizing a specific station interlocking logic function, a station yard graph can be displayed by depending on the computer interlocking system station yard data, so that dispatchers can operate and supervise the state of station signal equipment, and operation functions such as route arrangement, unlocking, turnout position conversion and the like are provided according to operation requirements. More specifically, the station yard data of the computer interlocking system is tle data, which includes device information such as signal machines, switches, sections, check points, crossing lines, buttons, indication lamps, train number frames, route delay unlocking frames, and insulation joints, connection relationships between devices (such as uplink connection relationships and downlink connection relationships), and interlocking relationships between interlocking devices (i.e., an interlocking route table), but the invention is not limited thereto.

Specifically, in this embodiment, the computer interlocking system yard data records general attributes (for example, the type, name, direction, index number Index, coordinates, DIMS number, control area, throat area, etc.) and specific attributes (for example, up-down connection relationship, direction, input/output interface, operation button, delay time, whether it is a switch with a large number, etc.) of each device, and these attributes can be used to assist in automatically generating the station yard graph. More specifically, by performing operation and analysis on station yard data of the computer interlocking system, attribute information such as the name of each device in the interlocking station yard, the name of the located section, the index number index, the type maintype, the direction (i.e., uplink or downlink), the throat area throat, the index number previdex of the front connection device, the index number nextindex of the rear connection device, another dynamic name of a double-acting turnout, another group of turnout names of cross-over lines, and the like can be identified. When the types of the equipment are signal, section track, check point check and switch, the index number of the equipment is usually numerical type. When the equipment type is an insulating joint deim, because the insulating joint is usually arranged between two connected turnouts, the index number of the equipment is defined by the index numbers of the turnouts on two sides of the equipment, the index number of the equipment is character type, and the format is a shift _ index _ deim _ turn _ index, wherein the shift _ index is the index number of the turnout on the left side, and the shift _ index is the index number of the turnout on the right side; for example, the switches on both sides of an insulating section have index numbers 71 and 72, respectively, where 72 is to the left of 71, and the insulating section has index number 72 \\\ u deim \ u 71. When the device type is cross transition line cross, four turnout names of the cross transition line are spliced to form an index number, double-acting turnouts are connected by using a minus, double-acting turnouts are connected by using a left-to-right, and the double-acting turnouts are sorted according to ASCII; for example, as shown in fig. 2, the names of the four switches related to the crossing line are 1, 3, 5, and 7, where switch 1 and switch 3 are double-acting and the index number of switch 1 is 35, the index number of switch 3 is 36, switch 5 and switch 7 are double-acting and the index number of switch 5 is 33, and the index number of switch 7 is 34, so that switches 1 and 3 are sorted to form 1-3, switches 5 and 7 are sorted to form 5-7, and 1-3 and 5-7 are sorted to form 1-3 and 5-7, and the index number of the crossing line is 1-3 and 5-7, but the present invention is not limited thereto.

With continued reference to fig. 1 to 8, the step S130 includes: correspondingly defining the type of the node according to the type of the equipment to obtain node data; acquiring a connection relation corresponding to the node (namely abstract equipment) according to the uplink connection relation and the downlink connection relation of the equipment; and acquiring connection relation data between the nodes according to the types and the connection relations of the nodes.

It is understood that the type nodetype of the node includes: end node EndNode (can define the end equipment of the line), passage node (can define the section, signal machine, check point and other equipment), switch node SwitchNode, cross node CrossingNode and insulating node DelimNode; the end node is provided with one phase, the channel node is provided with two phases, the turnout node is provided with three phases, the cross node is provided with four phases, and the insulating node is provided with two phases.

It is to be understood that the step of correspondingly defining the type of the node according to the type of the device includes: defining devices with types of semaphores, sections and checkpoints as the channel nodes; defining equipment with the type of a turnout as a turnout node; defining equipment with the type of a cross crossover line as the cross node; defining equipment with the type of the insulation joint as an insulation joint node; devices located at the yard boundaries (i.e., the ends of the line) are defined as the end nodes.

It is to be understood that the step of obtaining the connection relationship data between the nodes according to the types and the connection relationships of the nodes includes: and correspondingly connecting the phase of one node with the phase of another node according to the connection relation of the nodes to obtain the data of the connection relation between the nodes.

Specifically, in this embodiment, each device abstraction may be defined as a Node, and a connection phase of each Node may be determined, so as to represent devices and a composition relationship of the devices in the computer interlocking system yard data. More specifically, the application principle of the type nodetype of the node is as follows: as shown in fig. 3 (a) and 3 (b), the end nodes EndNode are adapted for station yard equipment connection terminals or stubs, representing yard boundaries; if no equipment is at the end of the yard line, an end node can be added directly to also represent the boundary. The end node EndNode is provided with a phase, and the phase can be marked as 0 or 1 in order to distinguish a right boundary from a left boundary; if the end node is set to have a phase of 0, as shown in fig. 3 (a), corresponding to the left boundary, it indicates that the right node can connect to another device (i.e., another phase of the node). If the end node is provided with a phase of 1, as shown in fig. 3 (b), corresponding to the right boundary, it indicates that the left node can be connected to other devices (i.e. another phase of the node).

As shown in fig. 4, the passage node is suitable for signal machines, sections, check points and other devices of the station yard equipment, that is, the other station yard equipment except for the devices located at the station yard boundary and the devices of the type of switch, cross-over and insulation node can be represented by the passage node; the passagennodeon is provided with two phases, respectively denoted 0 and 1, where phase 0 is located to the left of phase 1, and each phase can be connected to other devices (i.e. the phase of another of the nodes).

As shown in fig. 5 (a) to 5 (d), the switch node is suitable for the switch devices of the yard devices, and the switch nodes may be divided into 4 types according to the opening direction of the switch devices, and are respectively recorded as: the opening direction of the first type of turnout node is in an upper right opening direction; the opening direction of the second type turnout node is downward right; the opening direction of the third type turnout node is left-up; and the opening direction of the fourth type turnout node is left open. The turnout node is provided with three phases which are respectively marked as 0, 1 and 2, and each phase can be connected with other equipment (namely the phase of the other node); and for the first type of switch node, as shown in fig. 5 (a), the phase 0 and the phase 2 are located on the main section and the phase 0 is located at the left side of the phase 2; for the second type of switch node, as shown in fig. 5 (b), phase 0 and phase 1 are located on the main section and phase 0 is located on the left side of phase 1; for the switch nodes of the third type, as shown in fig. 5 (c), phase 0 and phase 1 are located on the main section and phase 0 is located on the right side of phase 1; for the fourth type switch node, as shown in fig. 5 (d), its phase 0 and phase 2 are located on the main section and phase 0 is located on the right side of phase 2.

As shown in fig. 7 (a) to 7 (c), the insulation node delirnode is used for recording an insulation node in a station facility, and the insulation node is used for separating sections and non-physical signal equipment. The insulated node delimNode has two phases, respectively 0 and 1, where phase 0 is located at the lower side of phase 1 and each phase can be connected to a switch on the corresponding side (i.e. the phase of the other node). Further, the insulating node delimpnode is not generated in the following case: (1) Insulation node nodes do not need to be generated among four turnouts related to the cross crossover; (2) As shown in fig. 8, if two connected switches are located in the same section name, i.e. they are located in one switch section, there is no need to generate an insulation node, but the invention is not limited thereto.

Specifically, in this embodiment, the structure of the node data includes two attributes, which are a node id and a node-type, respectively, where the node id may be determined according to an index number index corresponding to the device, and the node id is obtained by adding "node" to the index number index of the device; and further searching for a corresponding device type according to the index number index of the device, and determining the node type nodetype according to the searched device type. More specifically, if the index number index of the device is a numerical type, the device type is an annunciator signal, a segment track, a check point check or a switch, and the node type nodetype corresponds to a channel node PassageNode or a switch node; if the index number index of the equipment is a character type and the character string contains 'deim', the corresponding node type is an insulating node deimnode; and if the index number index of the equipment contains 'x', the node type corresponding to the node type is a cross node crossbar node.
