Abstract

The invention discloses an image navigation method based on a two-dimensional matrix. The image navigation method based on a two-dimensional matrix comprises the following steps of: establishing the two-dimensional matrix, mapping images to the two-dimensional matrix, navigating the images, and the like. The logic relation among images is expressed by using the two-dimensional characteristics of the matrix, so that image navigation is more flexible. When the relation among images is changed, the purpose can be achieved by only modifying the positions of corresponding elements in the matrix. The application efficiency is improved, and meanwhile, the demands of a user can be also satisfied better.

Description

Picture navigation method based on two-dimensional matrix

Technical field

The present invention relates to a kind of picture navigation method based on two-dimensional matrix.

Background technology

Present power supply dispatching system is structured on the configuration software, and the navigation of various pictures realizes the main manually interpolation link icon that relies on, and as navigating to picture B from picture A, then on picture A, adds a link icon to picture B.Though the purpose that this can reach picture navigation has strengthened application difficulty, also restricted the flexibility ratio of switching between the picture simultaneously.

Summary of the invention

The objective of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of picture navigation method based on two-dimensional matrix that solves flexible switching problem between the picture is provided.

The object of the invention is realized through following technical proposals: the picture navigation method based on two-dimensional matrix mainly may further comprise the steps:

(a) confirm laterally navigation and vertically the picture number of navigation in the traction electric power dispatching system, and set up the two-dimensional matrix of corresponding size, the also corresponding foundation of the logical relation between the picture is accomplished;

(b), be mapped to picture in the two-dimensional matrix according to the logical relation between the picture;

(c) horizontal ordinate through adding and subtracting current picture to be reaching the horizontal navigation of picture, and the ordinate through adding and subtracting current picture is to reach vertical navigation of picture.

Said two-dimensional matrix is 3 * 4 matrix, but is not limited to 3 * 4 matrix, can select the two-dimensional matrix of corresponding size separately according to different picture numbers.

In sum; The invention has the beneficial effects as follows: utilize the matrix two-dimensional characteristics to express the logical relation between the picture; Make picture navigation more flexible, when the relation between the picture changes, can achieve the goal in the position that only needs to revise respective element in the matrix; Improve application efficiency, also more can satisfy user's demand simultaneously.

Fig. 2 is the navigation synoptic diagram in the embodiment of the invention 1.

Embodiment

Below in conjunction with embodiment and accompanying drawing, the present invention is done further detailed description, but embodiment of the present invention is not limited only to this.

Embodiment:

The present invention mainly may further comprise the steps:

(a) confirm laterally navigation and the picture number of vertically navigating in the power supply dispatching system, and set up the two-dimensional matrix of corresponding size, the also corresponding foundation of the logical relation between the picture is accomplished;

(b) according to the logical relation between the picture, be mapped to picture in the two-dimensional matrix, the element in the matrix has not only shown the position relation of picture, the position of also having stored picture simultaneously, information such as size;

Its detailed process is: as shown in Figure 1, picture A is placed in to picture L in one 3 * 4 the matrix, and in this matrix, transverse axis is represented the relation that picture is geographically adjacent; The longitudinal axis representes that picture comprises and involved relation, geographically possibly be two adjacent slave station main wiring diagram pictures such as picture E and picture F, and picture A possibly be two identical geographic maps with picture B; They comprise picture E and picture F, and each element in the matrix not only comprises the picture title, also comprise the position of this picture in matrix simultaneously; (wherein X is the transverse axis coordinate to the subscript of this position use matrix element for X, Y) expression; Increase progressively successively since 0, Y is an ordinate, increases progressively successively since 0; List such as picture F second row two in matrix, (1,1) is represented in the position so; Therefore picture A is not random being placed in the matrix to picture L, is to place according to certain logical relation, that is to say that picture F is picture G on certain logical relation to the right, upwards is picture B, is downwards picture J, is left picture E, and other by that analogy.

In the traction electric system, each picture has certain relation on the geographic position, use this matrix can finely express the logical relation on this geographic position.

After having set up matrix according to Fig. 1; The also corresponding foundation of logical relation between picture and the picture is accomplished; According to rule shown in Figure 2, under the situation of confirming current picture title and the position in matrix, can be random switch to current picture relevant with it picture.

In Fig. 2, the coordinate of current picture in matrix be (X, Y); When navigating left; The X coordinate subtracts 1, obtain the adjacent with it left side picture coordinate for (X-1, Y); At this moment can obtain the picture title according to this coordinate, use this title to be revised as the picture after the navigation to current picture displayed then.Other to the right, upwards and downwards navigation type is seemingly.

This picture navigation is utilized the matrix stores image information, and combines certain navigation algorithm, and image information is carried out unified management, not only can be applicable to the situation of a picture display client, also can be applicable to the situation of a plurality of picture display clients.

As stated, just can realize the present invention preferably.

Claims

1. based on the picture navigation method of two-dimensional matrix, it is characterized in that, mainly may further comprise the steps:

(a) according to the number of slave station picture in the power supply dispatching system, confirm the size of matrix on transverse axis, confirm the size of matrix on the longitudinal axis according to the number of geographic map, contact net figure, supply arm synoptic diagram, two-dimensional matrix is set up thereupon;

(b), be mapped to picture in the two-dimensional matrix according to the logical relation between the above-mentioned picture;

2. the picture navigation method based on two-dimensional matrix according to claim 1 is characterized in that said two-dimensional matrix is 3 * 4 matrix.
