station diagram in operation, when one annunciator control is dragged to another annunciator control, the route (including simple route and composite route) of all composite conditions can be calculated, and the dragging operation is sent by the user.

The embodiment also has a function of calculating a composite route, specifically as shown in fig. 6, the steps of calculating the composite route include:

initializing an initial annunciator control, a terminal annunciator control and other component route controls of the route;

traversing the matched route end point annunciator control;

The annunciator control provides a menu, so that an arrangement way can be triggered by the menu, but the annunciator can only support the arrangement way of a simple route through the menu; the composite approach routing function is realized by dragging the annunciator control by a user.

The specific implementation process of this embodiment is as follows:

when the annunciator control is dragged, the starting annunciator control and the ending annunciator control are determined.

Traversing all routes of the station according to the station information and the direction of the initial annunciator control, and finding all routes matched with the initial annunciator control; checking whether the matched end signal control of each route is the same as the dragging end signal control, and if so, finding a route; if the destination signal control is different, the matched destination signal control is used as a new starting signal control, the station residual route is traversed, recursion is continued, and finally all the routes meeting the conditions are found out. The detailed flow chart is shown in fig. 6, and the effect is shown in fig. 7a and 7 b.

Example 3

and reducing or enlarging the section control according to the selection of the user.

And splitting the section control according to the selection of the user.

And calculating the position of the trolley control according to the train position information provided by the communication data.

On the track section control, a color block is used for identifying the position of the trolley control.

Specifically, the trolley position information includes a section number and offset where the trolley head is located, a section number and offset where the parking space is located, and section list information covered by the trolley. According to the running direction of the electric car, the sections are set to be in a train occupation state in proportion, and color blocks are used for displaying.

The specific implementation process of this embodiment is as follows:

drawing a long path: the section control is long in the actual project, but no excessive equipment exists in the middle, only a part of the traffic light is in a scene, and at the moment, the length of the section control can be shortened as far as possible as the control can put down the traffic light and no objection is generated, so that the space occupied by the part of the line in the station yard graph is saved. A specific example is shown in fig. 4.

When the trolley is on the road, the following steps are:

calculating the ID and offset of the section where the headstock control is located; the occupied position is the position from the start of the corresponding section to the offset, the logic lengths of the sub-sections are accumulated and summed when the total length of the section is equal, and the offset can cover one or more sub-sections.

Similarly, the ID and offset of the section where the tail control is located are calculated, and the occupied position is from the corresponding section offset to the section end point.

And traversing a section list completely covered by the trolley control, wherein the covered section is completely occupied.

As shown in fig. 8a, the train number window is parallel to the section where the train head control is located, and the horizontal position of the train number window does not exceed the abscissa of the occupied section on the canvas. In the case of the section being non-horizontal, as shown in fig. 8b, the train number window remains parallel to the section, e.g., the train number window rotates by ±45° or ±135° with respect to the horizontal direction, respectively.

The state of the section occupied by the trolley is updated continuously in the moving process of the trolley control, and the state of the section occupied by the history needs to be relieved.

When the trolley is running:

calculating the ID and offset of the section where the headstock control is located; the occupation position is the sum of the logical lengths of the sub-sections when the corresponding section offset reaches the end point of the section, and the offset can cover one or more sub-sections.

Similarly, the ID and the offset of the section where the tail control is located are calculated, and the occupied position is the position from the beginning of the corresponding section to the offset.

The train number window is parallel to the section where the train head control is located, and the horizontal position of the train number window does not exceed the abscissa of the occupied section on the canvas.

Please refer to embodiment 1 for other implementation procedures of this embodiment, and detailed descriptions thereof are omitted herein.

The specific implementation process of this embodiment is as follows:

the axle counting section data is organized to record which sections each axle counting section consists of.

The effective part sections of the axle counting sections are enumerated under the condition that the positions of the turnouts are different. For example, the axle counting sections 10402-10404DG are composed of 3 sections, and the two sections 1 and 2 are used for the switch positioning and the two

sections

2 and 3 are used for the switch reversing, as shown in FIG. 9.
