Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
As shown in fig. 1, the explanation control method for power system simulation training provided by the present invention is described in detail by taking the explanation of the power transformation equipment as an example, and specifically includes the following steps: firstly, segmenting the device explanation characters, dubbing the characters into a plurality of sections of voice according to the segments, forming voice sections and a subtitle configuration file, and then determining the angle of the power transformation device corresponding to each section of voice and a three-dimensional object of the part needing to be highlighted according to the segments; then a voice control animation curve is established. When the power transformation overhaul simulation training system is initialized, the initial color of the three-dimensional object of the part needing to be highlighted is recorded, and all voices and corresponding subtitles are read in through the voice section and the subtitle configuration file. The method comprises the steps of associating voice and corresponding subtitles with a voice control animation curve, playing the established voice control animation curve by a system when voice explanation is started, triggering and recording the voice one by one along with the driving of the animation curve, displaying the corresponding subtitles, automatically moving to a visual angle position and a direction corresponding to each voice through a set virtual camera, displaying the angle of power transformation equipment corresponding to the voice, and highlighting a part three-dimensional object explained by a voice content institute, explaining the structure, the action principle and the like of the power transformation equipment. When explaining other equipment of the power system, the virtual camera is only required to be automatically moved to the visual angle position and direction corresponding to each voice, and the other equipment angle corresponding to the voice is displayed, and the process is specifically described in detail below.
And S1, establishing a voice, a corresponding subtitle and a voice control animation curve required by equipment explanation, and determining a power transformation equipment angle corresponding to each section of voice and a part three-dimensional object required to be highlighted according to the sections.
When a piece of equipment explanation text is taken, firstly, decomposing the whole text into a plurality of small sections of text by taking a period as a breaking sign, and respectively storing each small section of text as a unit for displaying a caption; then dubbing each small segment of characters according to the normal reading speed, and respectively storing the dubbing of each small segment of characters; and finally, combining the text information and the corresponding voice information to establish a voice section and a subtitle configuration file. As shown in fig. 2, in the voice section and subtitle configuration file, one row represents a correspondence of a section of voice to a subtitle, and the voice storage path and the corresponding subtitle are separated by "& _" as a separator. Each voice storage file can be found through the voice storage path.
The transformer overhaul simulation training system is developed by adopting a unity development environment, the animation curve is established by an animation editor of the unity development environment, and any curve can be established in the animation editor by inserting a key frame aiming at a certain parameter value and is stored in an animation form. When the animation begins to play, the y-axis value changes along with the change of the curve along with the lapse of the x-axis. In the embodiment provided by the invention, the voice control animation curve is constructed on the basis of the animation curve. When the voice control animation curve is constructed, a control parameter Controller is used as a y-axis, and the value of the y-axis changes along with the change of the curve along with the transition of an x-axis. The Controller parameter is used as a control parameter, and when the x time axis changes continuously along with the time, the Controller parameter continuously triggers corresponding voice and subtitles. And the Controller parameter determines the number of animation key frames to be established according to the number of information pieces in the voice section and the subtitle configuration file. When n segments of voice are to be controlled to play, n +2 animation key frames are required to be established according to the Controller parameter. The 1 st frame is a starting frame, the n +2 th frame is an ending frame, and the middle n animation key frames are trigger frames of n sections of voice. And manual intervention is not needed, the triggering accuracy is improved, and the error occurrence probability is reduced.
As shown in fig. 3, the 1 st frame is established as a start frame at a time position of 0.00 second, and the Controller parameter value is less than 0. Establishing a 2 nd frame at a proper position of a time axis of more than 0.0 second, setting a Controller parameter value to be 0, and using the parameter value as a trigger point for playing the 1 st section of voice and the subtitles to start playing; in the embodiment provided by the invention, when the reserved time at the proper position of the time axis is the time for initializing the power transformation overhaul simulation training system, the recorded voice and the corresponding subtitle are read in and are associated with the voice control animation curve. Establishing a 3 rd frame at a time axis position longer than the 1 st voice length, setting a Controller parameter value as 1, and using the Controller parameter value as a trigger point for starting playing the 2 nd voice and the caption; at this time, the time represented by the position of the time axis greater than the length of the 1 st voice is the sum of the pause time of each small segment in the voice recording process and the recording time of the 1 st voice. And by analogy, establishing an n +1 th frame at a time axis position longer than the length of the n-1 th voice, and setting a Controller parameter value as n-1 as a trigger point for starting playing the nth voice and the subtitles. And establishing an n +2 th frame at a proper position of a time axis with the length larger than the nth voice, and setting a Controller parameter value as n to be used as an end frame. Taking the mth frame (any frame) as a reference, and linearly changing the Controller parameter value between the mth frame and the m-1 th frame; between the m-th frame and the m + 1-th frame, the linear change of the Controller parameter values also ensures that the voice between every two frames is played at a constant speed, and each Controller parameter value corresponds to the voice and the caption information at a time position. A device explains that characters correspond to a voice control animation curve, and the voice control animation curve controls playing and switching of multiple sections of voice and corresponding subtitles through Controller parameters.
Meanwhile, the angle of the power transformation equipment corresponding to each section of voice and the three-dimensional object of the part needing to be highlighted are determined according to the sections. In the embodiment provided by the invention, when the power transformation equipment is explained by voice, a virtual camera is arranged in the power transformation overhaul simulation training system, different angles of the power transformation equipment are played through the change of the visual angle position and direction of the virtual camera according to different voice contents, and a three-dimensional object of a part which is mainly explained by the voice contents is highlighted through color change. The method for determining the angle of the power transformation equipment corresponding to each section of voice and the three-dimensional object of the part needing to be highlighted according to the sections specifically comprises the following steps:
and S11, establishing a virtual camera which can play all angles of the power transformation equipment related to the explanation characters of the equipment according to the change of the visual angle position and direction.
And S12, establishing the visual angle position and direction of the virtual camera corresponding to the content of each speech explanation, and determining the part three-dimensional object needing to be highlighted.
In the embodiment provided by the invention, each piece of voice corresponds to the visual angle position and direction of one virtual camera, and the visual angle position and direction of the virtual camera are a certain point in the three-dimensional coordinate where the virtual camera is located when the virtual camera can display a certain angle of the power transformation equipment. And determining the angle of the power transformation equipment required to be displayed on the screen according to the content of each voice explanation, and storing a three-dimensional coordinate position corresponding to a certain point in the three-dimensional coordinate where the virtual camera is positioned when the angle is displayed into an array DirectionandGlitterGRP as the visual angle position and direction of the corresponding virtual camera so as to be used for explaining the power transformation equipment subsequently.
In addition, for the content of each speech explanation, a part three-dimensional object related to the content is determined and stored in the array DirectionandGliterGRP, so that the part three-dimensional object is used when highlighted in order to highlight the pertinence of the explanation, improve the authenticity and the explanation efficiency of the explanation when the power transformation equipment is explained later.
And S13, storing the visual angle position and direction of the virtual camera corresponding to each piece of voice, the three-dimensional object of the part to be highlighted and the initial color of the three-dimensional object of the part to be highlighted in an array DirectiondGlitterGRP.
And S2, extracting the initial color of the three-dimensional object of the part needing to be highlighted when the power transformation overhaul simulation training system is initialized, and reading the recorded voice and the corresponding subtitles.
When the transformer overhaul simulation training system is initialized, the stored initial color of the part three-dimensional object needing to be highlighted is extracted from the array DirectionandGlitterGRP and used for restoring the part three-dimensional object to the initial state after a certain section of voice is played.
In addition, when the power transformation overhaul simulation training system is initialized, recorded voice and corresponding subtitles also need to be read in so as to be conveniently associated with the voice control animation curve subsequently, and corresponding voice and corresponding subtitles are played while the voice control animation curve is played. As shown in fig. 4, when the transformer substation overhaul simulation training system is initialized, the external voice segment and the subtitle configuration file are opened in a data stream manner, and the internal information of the voice segment and the subtitle configuration file is read line by line. Each row of data is separated by "& _" as a separator, stored in a temporary array str, and added to a temporary container arrrist. And closing the data stream until the contents in the voice section and the subtitle configuration file are completely read, and assigning the contents in the temporary container arrlist to the dataArray container.
And extracting a voice storage path from each element of the dataArray container, finding voice information according to the voice storage path, and storing the voice information into the audioArray container.
And S3, associating the voice and the corresponding subtitles with the voice control animation curve, playing the voice control animation curve, performing voice and subtitle playing and switching processing, displaying the corresponding transformation equipment angle according to the voice playing content, and highlighting the three-dimensional object of the related part.
And after the recorded voice and the corresponding subtitles are read in, associating the voice and the corresponding subtitles with the voice control animation curve through a Controller parameter of the voice control animation curve. When an equipment explanation text of the transformer overhaul simulation training system can be decomposed into n sections of voice for playing, n +2 animation key frames are established corresponding to the Controller parameters, and each animation key frame corresponds to one Controller parameter value. The method comprises the following steps that a frame 1 is a starting frame, a frame n +2 is an ending frame, n animation key frames in the middle are trigger frames of n sections of voice, each trigger frame corresponds to a section of voice and a section of subtitle trigger point, a Controller parameter gradually increases along with the time, and when the m-th animation key frame corresponding to the Controller parameter and serving as the trigger frame is reached, a speech section m-1 and a subtitle section m-1 are respectively extracted from an audio array container and a dataArray container and played. At this time, the Controller parameter reaches a specific parameter value m-2, which is an integer greater than or equal to zero in the embodiment of the present invention. Meanwhile, the visual angle position and direction of the virtual camera corresponding to the (m-1) th section of voice and the part three-dimensional object needing to be highlighted are extracted from the array DirectionandGlitterGRP. And starting the coordinate and direction transformation processing of the virtual camera to enable the virtual camera to move in a three-dimensional space along with the playing of the voice, and simultaneously starting the processing of highlighting the three-dimensional object of the designated part.
As shown in fig. 5, the principle of moving an object from point a to point b in three-dimensional space is as follows:
in the three-dimensional space, the vector of the point a is Ia, the vector of the point b is Ib, and when the object is to move from the point a to the point b, the vector Ic from the point a to the point b needs to be obtained. The vector Ia and the vector Ib are subtracted to obtain Ic: and Ic is Ib-Ia.
The direction of the vector Ic is the direction of the object motion, and the modulus is the distance of the object motion.
In order to realize the reality of simulation and better understand the power transformation equipment, the current power transformation equipment model mainly adopts a three-dimensional graph, and the visual angle position and the direction of a virtual camera continuously move along with the continuous playing of recorded voice so as to realize the display of different angles of the three-dimensional graph of the power transformation equipment on a screen. When the m-1 section of voice is played, the visual angle position and the direction of the virtual camera corresponding to the m-1 section of voice are extracted from the array DirectionandGlitterGRP, and then the direction and the distance which the virtual camera needs to move if the angle of the power transformation equipment corresponding to the current voice is required to be displayed are obtained according to the vector Ia1 of the point a1 where the virtual camera is currently located and the vector Ib1 of the point b1 (target point) represented by the visual angle position and the direction of the virtual camera corresponding to the m-1 section of voice in the three-dimensional space. Where the direction is the direction of vector Ic 1: ic1 ═ Ib 1-Ia 1. The norm is the distance moved by the virtual camera. As the virtual camera moves to the target point, the mode of the Ic1 gradually decreases, and when the value is not greater than 0.005, the virtual camera is considered to reach the designated position, the virtual camera stops moving, and the angle of the power transformation equipment irradiated by the virtual camera when the virtual camera is displayed on the screen at the target point b 1. The angles of the power transformation equipment corresponding to the voice, the caption and the voice content are consistent, the reality of simulation is improved, and the power transformation equipment can be known more fully.
Besides, when the (m-1) th voice is played, the information of the part three-dimensional object (target three-dimensional object) which is corresponding to the (m-1) th voice and needs to be highlighted is extracted from the array DirectionandGlitterGRP, and in the embodiment provided by the invention, the highlighting effect of the target three-dimensional object shows that the color presents a gradually-changed flickering effect. The method specifically comprises the following steps:
firstly, an interpolation value t is set between an initial color a of a target three-dimensional object extracted when a power transformation overhaul simulation training system is initialized and a finally displayed color b, and the t is changed from 0 to 1. Returning to a when t is 0; return b when t is 1. And then setting a Sin sine wave function, taking the return value of the Sin sine wave function as the value of the interpolation t, changing the color of the target three-dimensional object from the color a to the color b along with the change of the Sin sine wave function along with time, realizing the effect of color gradual change and flicker, enabling the three-dimensional object of the part designed by voice to be highlighted and concentrated in attention in the explanation process, and improving the explanation effect. And after the voice playing is finished, restoring the initial color of the part three-dimensional object related to the voice.
And gradually increasing the parameter value of the Controller parameter along with the time, gradually reaching a trigger frame at a higher layer, and extracting the voice and the corresponding subtitles from the audio array container and the dataArray container one by one according to the voice and subtitle storage sequence to play the voice and the subtitles. Along with the playing of voice and subtitles, the virtual camera gradually rotates to display the corresponding view angle of the power transformation equipment and highlight the related three-dimensional objects of the parts, so that the reality and pertinence of simulation are improved, and the power transformation equipment can be known more fully.
When the transformer overhaul simulation training system begins to explain the transformer equipment, the voice control animation curve begins to play, when the Controller parameter value is 0, the trigger frame triggers the first section of voice of the corresponding equipment explanation text and the caption corresponding to the first section of voice, and the first section of voice and the corresponding first section of caption are respectively extracted from the audio array container and the dataArray container and played. Meanwhile, the visual angle position and direction of the virtual camera corresponding to the first voice and the part three-dimensional object needing to be highlighted are extracted from the array DirectionandGlitterGRP. And starting the coordinate and direction transformation processing of the virtual camera to enable the virtual camera to move in a three-dimensional space along with the playing of the voice, and simultaneously starting the processing of highlighting the three-dimensional object of the designated part. And displaying the angle of the power transformation equipment related to the voice on the screen, and highlighting the related part three-dimensional object. And (3) as time goes on, gradually increasing the Controller parameter value, sequentially triggering the voice and the corresponding subtitles until all the voice and subtitles in the audio array container and the dataArray container are completely played, wherein the Controller parameter value is n, the voice control animation curve reaches an end frame, the explanation is finished, the virtual camera returns to the initial position, the initial angle of the power transformation equipment is displayed, and all the part three-dimensional objects are restored to the initial color. A device explains that characters correspond to a voice control animation curve, and the voice control animation curve controls playing and switching of multiple sections of voice and corresponding subtitles through Controller parameters. In the whole playing process, human intervention is not needed, the triggering accuracy is improved, and the error occurrence probability is reduced.
In summary, in the explanation control method for the simulation training of the power system, the explanation text of one piece of equipment is decomposed into a plurality of small sections of text which are used as the units for displaying the subtitles and are stored respectively; dubbing each small segment of characters, associating the dubbing and the subtitles of each small segment of characters with a voice control animation curve, and realizing the playing and switching processing of the voice and the subtitles in the explanation process of the equipment through the voice control animation curve, wherein the whole process does not need human intervention, thereby improving the triggering accuracy and reducing the error occurrence probability; in addition, synchronous control processing of three-dimensional graphics, voice and subtitles of the power transformation equipment and highlighting processing of three-dimensional objects of related parts can improve reality of simulation, well meet training requirements and achieve expected training effects.
