The man-machine interaction module is an interface between the system and a user. The module provides two basic data display modes of a GIS graph and a station yard graph, provides a graphical operation interface, accurately transmits the operation intention of a user to other modules, and timely displays the operation result.

In a second aspect, the present application provides a source data management method fusing geospatial information

The invention constructs an upper data set by taking stations as a basic unit, equipment contained in each station is divided into a track section, a turnout, a signal machine, a beacon and a platform according to types, and each equipment simultaneously records a geographic coordinate and a kilometer post.

For compatibility with existing rail transit representations, the yard graph is also kept separately as an integral part of the source data, as shown in fig. 2.

For track sections, including sub-types such as tracks, interval tracks and in-station connecting lines, the invention models the track sections into a fitting curve formed by characteristic points which are connected in front and back, and the geographic coordinates and kilometers of the points are recorded in source data. The type data feature items comprise equipment names, equipment sub-types, kilometer post types, feature point numbers, longitude and latitude of each feature point, kilometers posts of each feature point and gradient of each feature point.

For the turnout, the turnout is modeled into a plurality of curves led out from the center of the turnout, wherein the number of the turnout is 1 before the turnout, and the number of the turnout after the turnout is consistent with the number of the branches. Each curve is further modeled into a curve formed by characteristic points which are connected in front and back, and the geographic coordinates and the kilometer posts of the points are respectively recorded.

For a station, the invention models the station as a set consisting of a plurality of 5 devices. The type data characteristic items comprise station names, station codes and various administered equipment serial numbers.

For the station yard graph, each graph is composed of a plurality of stations, and the display form is manually designed according to the logical relationship among all devices. The invention abstracts station data into 6 types of track sections, turnouts, signal machines, stations, train number windows and station names, records the names and boundary point plane coordinates of each type of equipment, wherein the track sections comprise first and last boundary points, the turnouts comprise turnout centers and branch end points, the signal machines comprise base points, pointing angles, lamp numbers and long and short arm attributes, the stations comprise upper left corner boundary points, lengths and widths, and the station names comprise the upper left corner boundary points.

The station map data is derived from the professional design drawings of the rail transit signals.

The source data of the invention is stored and updated according to stations, and the system provides tool software for converting the original acquisition data into the source data.

In a third aspect, the present application provides a dynamic definition and automatic update method for electronic map

The electronic map is generated by taking a line as a unit, and a single line corresponds to a single file. The route is composed of a plurality of stations with connection relations and a plurality of station yard graphs. In the same road network, the lines are uniquely identified by line codes.

The dynamic definition process of the electronic map comprises the following steps:

a user selects to newly build a line or modify an existing line; if a new line is built, the system automatically distributes line codes to the new line according to the increasing sequence; if the existing line is modified, popping up a list box by the system according to the line code for a user to select;

In a fourth aspect, the present application provides a method for detecting integrity of electronic map data

The method for detecting the integrity of the electronic map data can be divided into 5 parts, namely, the integrity of single equipment, the connection relation of lines, the consistency of signal machines, the consistency of beacons, the consistency of station maps and the like.

For single device integrity, the detection object is a single track section or a single switch. For the track section, the length between two adjacent characteristic points is calculated according to the geographic coordinate and the kilometer post, and the data is considered to be abnormal when the difference between the two lengths is larger. For the turnout, the method calculates the length of each bifurcation direction according to the geographic coordinate and the kilometer post respectively, and when the two lengths are greatly different, the data is considered to be abnormal. In addition, the uniqueness of the names of the devices in a single station is confirmed, and the geographic coordinates of the devices are required to be within the appointed range of the station.

For the line connection relationship, the detection object is the position relationship between the track section and the turnout. The invention determines the connection relation between the devices according to the geographic coordinate value proximity degree of each device endpoint. If some equipment is not an end line and an end point without a connection relation exists, the equipment is judged to be abnormal in breakpoint. If 1 end point of a certain device is connected with more than 2 other devices, the device is judged to be abnormal with multiple intersection points. If the kilometer sign values of the two end points which are mutually connected are inconsistent, the kilometer sign is judged to be abnormal in succession. And if all the equipment of a certain station has no connection relation with other stations, judging that the station connection is abnormal. After the local map data is detected through the line connection relation, the geographic space structure and the logic structure of the line are accurately described, and bidirectional conversion between the kilometer post and the geographic coordinate can be realized.

For the consistency of the signal machines, the detection objects are the position and the two side devices of the signal machine. The invention calculates the geographic coordinate according to the actual measurement kilometer post of the signal machine, and then compares the geographic coordinate with the actual measurement geographic coordinate to check the position consistency. The invention checks the connection relation between the front side equipment and the back side equipment of each annunciator, calculates the distance between the geographical position of the connection end point and the actually measured geographical position of the annunciator, and checks the consistency of the corresponding relation.

For beacon consistency, the detection objects are the location of the beacon and the associated devices. According to the method, the geographic coordinate is calculated according to the actual measurement kilometer post of the beacon, and then the geographic coordinate is compared with the actual measurement geographic coordinate, so that the position consistency is verified. The invention verifies that the actually measured geographic position of the beacon is in the geographic space range of the associated track section or turnout, and the consistency of the corresponding relation is verified.

For the consistency of the station yard graphs, the detection object is the consistency of the logical relation and the real logical relation of the station yard graphs. For track sections and turnouts connected in a station yard graph, the method verifies whether the connection relationship also exists in the measured geographic space. For the signal machine in the station field diagram, the invention checks whether the front side equipment and the back side equipment are consistent with the signal machine attribute value in the source data. For a station appearing in the station yard graph, the invention checks whether it is in the sequence of stations defined by the route.
