Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow diagram of a method for determining a primitive link relationship according to the present invention. Referring to fig. 1, an embodiment of the present invention provides a method for determining a primitive link relationship, where the method may include: step 110, step 120 and step 130.
It should be noted that the execution subject of the primitive link relation determining method provided by the present invention may be an electronic device, a component in an electronic device, an integrated circuit, or a chip. The electronic device may be a mobile electronic device or a non-mobile electronic device. By way of example, the Mobile electronic device may be a Mobile phone, a tablet Computer, a notebook Computer, a palm top Computer, a vehicle-mounted electronic device, a wearable device, an Ultra-Mobile Personal Computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-Mobile electronic device may be a server, a Network Attached Storage (NAS), a Personal Computer (PC), and the like, and the present invention is not limited in particular.
The following describes the technical solution of the present invention in detail by taking a computer as an example to execute the method for determining primitive link relation provided by the present invention.
And step 110, determining the position information of the key point corresponding to the target turnout primitive based on the position information of the target turnout primitive and the equipment attribute information corresponding to the target turnout primitive.
It can be understood that the CAD can be developed secondarily by using the AutoLISP language embedded in the CAD to obtain an algorithm capable of automatically generating the connection relation of the turnout primitive, and the algorithm can be applied to the embodiment of the invention.
The AutoLISP language is a programming language formed by expanding a plurality of functions suitable for CAD application on the basis of the common LISP language. It is an explanatory evaluation language, slow in speed, hard to keep secret, able to be edited by any word editing software and stored in pure text format.
Before the signal plane layout drawing is carried out, a local drawing base can be established, namely each equipment primitive is drawn based on a primitive standard base. The standard primitives of various types of equipment are stored locally, for example: switch primitives, track primitives, or semaphore primitives, etc., which are not specifically limited herein.
In step 110, the position information of the target switch element may be represented by coordinates of the insertion point of the target switch element, and similarly, the position information of other device elements may also be represented by coordinates of each device element in the signal plane layout diagram.
The device attribute information may include a device number, a device name, a device belonging zone, a belonging concentration area, a belonging interlocking area, a belonging station, or the like, and is related to characteristics of the device itself. The device attribute information of the target switch element is shown in fig. 2.
Since the link relationship of the target switch primitive needs equipment attribute information such as the equipment number of the switch peripheral equipment, before the link relationship of the target switch primitive is generated, the equipment attribute information such as the equipment number of the switch peripheral equipment, such as the equipment name of the track equipment, needs to be determined. If the attribute of the related device is not filled in, the link relation is null.
The position information of the target turnout primitive can be obtained by calling a function in the AutoLISP function library, and similarly, the position information of the key point of the target turnout primitive can also be obtained by using the function in the AutoLISP function library.
In actual implementation, the coordinates of the insertion point of the target turnout primitive can be obtained first, then the key point is determined according to the coordinates of the insertion point of the target turnout primitive and the length of the turnout, so that the relative position coordinates of the key point corresponding to the target turnout primitive relative to the insertion point of the target turnout primitive are determined, and finally the absolute coordinates of the key point are determined according to the relative coordinates.
Because operations such as primitive scaling and turning exist in the drawing process of the target turnout primitive, the influence of the situation needs to be considered when the position information is acquired, otherwise, an incorrect link relation may be generated.
As shown in FIG. 3, there is a primitive insertion point B in rectangular box 310, a primitive node A in rectangular box 320 (which is a dynamic block), a primitive node C in rectangular box 330, a primitive node D in rectangular box 340, and a primitive node E in rectangular box 350.
Acquiring the position information of key points A, C, D and E by the following method:
(1) acquiring the coordinate of the primitive insertion point B by calling a function in an Autolisp function library;
(2) respectively acquiring relative position coordinates of a point A, a point C, a point D and a point E relative to a primitive insertion point B;
(3) since the primitive may have operations such as flipping during rendering, the primitive is modified according to the relevant parameters on the basis of (2), for example: regarding the x-axis inversion, the relative position coordinates in (2) need to be corrected to obtain actual coordinates.
(4) And (4) respectively calculating absolute coordinates of the point A, the point C, the point D and the point E according to the coordinates of the insertion point B and the relative position coordinates of the point A, the point C, the point D and the point E obtained in the step (3).
And step 120, determining the relative position information of the associated equipment graphic elements corresponding to the target turnout graphic elements based on the position information of the key points.
After the position information of the key point is determined, the associated equipment primitives and the relative position information of the associated equipment primitives which accord with the rules can be obtained through filtering according to the equipment types, and the obtained information is used for updating the equipment attribute information of the target turnout primitive.
And the relative position information is the position information of the associated equipment primitive relative to the target turnout primitive.
And step 130, determining the link relation between the target turnout element and the associated equipment element based on the relative position information of the associated equipment element.
After the accurate position information of the turnout key point is obtained, the link relation between the target turnout primitive and the associated equipment primitive can be automatically calculated, and finally the link relation is stored into the equipment attribute information of the target turnout primitive.
The method for determining the primitive link relation can rapidly determine the link relation between the target turnout primitive and the associated equipment primitive by acquiring the position information of the key point of the target turnout primitive, improve the drawing efficiency, simplify the determination process of the link relation and reduce the error rate of the generation of the link relation.
In some embodiments, determining the relative position information of the associated device primitive corresponding to the target switch primitive based on the position information of the key point includes:
determining a target graph entity based on the position information of the key points and the end points of the target turnout primitive;
based on the target graphics entity, relative position information for the associated device primitive is determined at the target orientation.
In actual implementation, after the position information of the key points of the target turnout primitive is obtained, a selection set is formed by adopting a proper target graphic entity at the end point of the target turnout primitive.
Common target graphic entities may include line segments, rectangles, polygons, and circles. And then filtering the selection set to obtain associated equipment primitives of the target turnout primitives in the target azimuth, and finally obtaining and storing the link relation between the target turnout primitives and the associated equipment primitives.
As shown in FIG. 3, the target graphical entity may include a dashed segment 360, a dashed segment 370, and a dashed segment 380 in the figure. The dotted lines may correspond to different target orientations.
The method for determining the primitive link relation can rapidly determine the associated equipment primitive and the position information of the associated equipment primitive by using the position information of the end point and the key point of the target turnout primitive without considering the primitive drawing sequence through the target graphic entity.
In some embodiments, the target position includes at least one of: the front fork, the back fork and the back fork are reversed and positioned.
The associated connected device primitives corresponding in target orientation may be determined by the target graphics entity. The graphic entity at the target orientation may include a fork front portion, a fork rear flip portion, and a fork rear positioning portion.
As shown in fig. 3, the broken line segment 360 corresponds to the front branch portion, the broken line segment 370 corresponds to the rear branch positioning portion, and the broken line segment 380 corresponds to the rear branch reversed portion. And determining the associated equipment graphic elements connected with the target graphic entity through the position information of the key points and the end points of the target turnout graphic elements.
As shown in fig. 4, for the devices connected to the front branch portion (solid line segment 420) and the rear branch positioning portion (solid line segment 410), for example: a rectangle may be drawn at the key point a, and an associated device primitive (e.g., track C) intersecting the rectangle may be selected according to the rectangle, and filtered according to the device type to obtain a device primitive meeting the rules. The track C is the rear device behind the fork, and the information of the track C can be filled in the rear device in fig. 2.
As shown in fig. 5, for the device connected to the switch back transposition portion, it is necessary to obtain the coordinates of the points C and D, extend the line segment CD to the point F, draw a line segment with the point F as the center, select the intersecting device according to the line segment, and then filter to obtain a device that meets the rules, where the track a is the switch back transposition device, and the information of the track a can be filled into the transposition device in fig. 2.
In some embodiments, determining the link relationship between the target switch primitive and the associated device primitive based on the position information of the associated device primitive comprises:
determining the relative position relation of the associated equipment primitive and the target turnout primitive based on the relative position information of the associated equipment primitive;
and determining the link relation between the target turnout primitive and the associated equipment primitive based on the relative position relation of the equipment.
In an actual implementation, after determining the relative position information of the associated device primitive, the device relative position relationship of the associated device primitive and the target switch primitive may be determined, and the device relative position relationship may include a front device, a rear device, and a flip device. Based on the relative position relationship of the equipment, the link relationship between the target turnout primitive and the associated equipment primitive can be automatically generated.
In some embodiments, after determining the link relationship between the target switch primitive and the associated device primitive based on the relative position information of the associated device primitive, the method further includes:
and under the condition of updating the equipment attribute information of the target turnout primitive, updating the link relation between the target turnout primitive and the associated equipment primitive.
Under the condition of modifying the equipment attribute information of the target turnout primitive or modifying the primitive attribute information, a new equipment relative position relation corresponding to the target turnout primitive can be generated, so that the link relation between the target turnout primitive and the associated equipment primitive can be updated, and the updated link relation is stored into the equipment attribute information of the target turnout primitive.
The method for determining the primitive link relation can automatically complete the update of the turnout link relation when the equipment attribute information of the target turnout primitive is updated, and improves the efficiency and the accuracy.
In some embodiments, after determining the link relationship between the target switch primitive and the associated device primitive based on the relative position information of the associated device primitive, the method further includes:
under the condition that the to-be-drawn primitive and the target turnout primitive are the same in equipment type, obtaining a current drawing primitive based on the target turnout primitive;
updating the equipment attribute information of the current drawing primitive based on the primitive link relation contained in the current drawing primitive;
and the link relation between the target turnout primitive and the associated equipment primitive is the same as the link relation of the primitive contained in the current drawing primitive.
In actual implementation, a line usually has a partially similar primitive arrangement and a plurality of site maps, and when other similar primitives are drawn, the drawing can be performed in a copying manner, and at this time, the device attribute information and the link relationship of the primitives are automatically copied.
Under the condition that the to-be-drawn primitive and the target turnout primitive are the same in equipment type, the target turnout primitive is copied, the current drawing primitive can be obtained, and the current drawing primitive is displayed on the drawing.
It can be understood that the link relationship between the target switch primitive and the associated device primitive is the same as the primitive link relationship contained in the current drawing primitive, and the primitive link relationship contained in the current drawing primitive can be directly stored in the device attribute information of the current drawing primitive.
Under the condition of modifying the equipment attribute information such as the equipment number of the current drawing primitive and the like, a new equipment relative position relation corresponding to the current drawing primitive can be generated, so that the primitive link relation contained in the current drawing primitive can be updated, and the updated primitive link relation is stored into the equipment attribute information of the current drawing primitive.
The method for determining the primitive link relation can support the drawing of the current drawing primitive by copying the target turnout junction diagram, and obviously improves the drawing efficiency.
In some embodiments, the automatic generation method of the switch primitive link relationship under CAD secondary development based on the AutoLISP may include the following two application scenarios.

(3) and clicking to generate the front-back relationship of the equipment, and automatically updating and storing the connection relationship of the turnout primitives to the corresponding attributes of the turnout primitives.
