Description
Technical Field
The invention relates to the technical field of electronics, in particular to a method and a device for controlling a large screen.
Background
With the rapid development of computer multimedia technology and the widespread application of network technology, there are large-screen, multi-color, high-brightness, high-resolution display requirements in many places such as command and monitoring centers, network management centers, conference centers, etc. Since the conventional CRT display hardly satisfies the above requirements, a large screen display technology rapidly developed in recent years becomes an effective way to satisfy the requirements of color large-screen display.
Because the large screen is generally customized and does not carry information input equipment, when the large screen displays information, such as graphics or characters, to be displayed, which is configured to the large screen in advance, is generally displayed statically, when the large screen needs to be controlled, such as the display mode (screen resolution and interaction mode) of the large screen or the information (display content and display effect) displayed by the large screen is adjusted or edited, a corresponding control command can be manually input on a control terminal configured with a large screen control interface, such as a computer, through an operation device externally connected with the control terminal, and the large screen is controlled through the control command. Because the process of manually inputting the control command is complicated, the control command can be obtained in a voice acquisition mode under normal conditions in order to reduce the dependence on an operation device externally connected with the control terminal in the process of obtaining the control command and reduce the time consumed by obtaining the control command.
Although the dependence on an operation device externally connected with the control terminal can be reduced by acquiring the control command of the large screen in a voice acquisition mode, and the time consumed for acquiring the control command of the large screen is reduced, because the acquired voice needs to be a relatively standard voice control command when the control command of the large screen is acquired by acquiring the voice, and the situation that the acquired voice cannot be identified can occur when the acquired voice comprises voice information except the voice control command, the standard degree requirement on the acquired voice in the scheme is relatively high, so that the success rate of acquiring the control command of the large screen is reduced, the time consumed for acquiring the control command of the large screen is prolonged, and the efficiency of controlling the large screen is reduced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used for distinguishing the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like are not limited in number or execution order.
In general, a large screen is mainly customized, content displayed on the large screen may be preset or may be set by a terminal connected to the large screen, where the terminal connected to the large screen is generally configured with a dedicated large screen control interface, and a user operates the large screen control interface through the terminal to achieve the purpose of editing or modifying the content displayed on the large screen. Since most of large screen control interfaces are customized, when a large screen is controlled, a series of parameters such as screen resolution, network conditions, display contents, display effects, and interaction modes need to be set in more detail, the setting of the parameters can be usually input through an operation device externally connected to the control terminal, and meanwhile, a user can also input other control commands through the operation device externally connected to the control terminal to control the large screen. The process of controlling the large screen is complex and tedious, the time consumed for controlling the large screen is increased, and the efficiency of controlling the large screen is reduced. In order to reduce the dependence on an external operating device of the control terminal in the process of acquiring the control command and reduce the time consumed by acquiring the control command, the control command can be acquired in a voice acquisition mode under normal conditions.
Although the dependence on an operation device externally connected with the control terminal can be reduced by acquiring the control command of the large screen in a voice acquisition mode, and the time consumed for acquiring the control command of the large screen is reduced, when the control command of the large screen is acquired by acquiring voice, the acquired voice needs to be a relatively standard voice control command, and when the acquired voice includes voice information except the voice control command, an unrecognizable situation can occur. For example, when the standard voice control command is "next" and the collected voice is "switch to next", it may be impossible to recognize the collected voice as a control command. Therefore, the requirement on the standard degree of the collected voice is high in the scheme, so that the success rate of obtaining the control command of the large screen is reduced, the time consumed for obtaining the control command of the large screen is prolonged, and the efficiency of controlling the large screen is reduced.
In order to solve the above problem, as shown in fig. 1, an embodiment of the present invention provides a method for controlling a large screen, including:
101. and voice information is collected.
Specifically, the voice information may be voice information of the user, the voice information of the user includes information sent by the user in a voice manner for controlling the large screen, and the collecting of the voice information may be collecting the voice information of the user through a microphone on the mobile terminal of the user.
For example, voice information may be collected by pressing a voice remote control button on the user's mobile terminal for the user and inputting the voice information through a microphone on the user's mobile terminal. The collected voice information may be "how much apple brands sold in Beijing are sold in the special topic of sale", and the information which is sent by the user in a voice manner and is used for controlling the large screen may be understood as follows: and displaying the data of apple brand sales in Beijing in the special sale topic of the screen.
102. And converting the voice information into character strings.
Specifically, the voice information is converted into a character string, and the voice information can be converted into the character string by calling a voice analysis component.
103. And acquiring a control instruction according to the keywords matched with the characters in the character string in the instruction set.
Wherein the control instruction is used for controlling the large screen.
Specifically, the instruction set may be configured in advance or may be obtained from another device or system, the instruction set may include one or more keywords, the keywords in the instruction set may each correspond to a control command or an operation action for controlling the large screen, that is, the instruction set may be regarded as a set of control commands or operation actions for controlling the large screen, by matching the instruction set with characters in a character string, the determined keyword in the instruction set that matches the characters in the character string may be regarded as a control command or an operation action for controlling the large screen included in the character string, and a control instruction for controlling the large screen may be obtained according to the part of keywords, that is, information for controlling the large screen in the collected voice information is converted into a control instruction capable of controlling the large screen.
Further, each keyword in the instruction set may have a corresponding code, and performing structured output on one or more codes may obtain a corresponding control instruction, so that when a keyword matching a character in a character string in the instruction set is determined, a code corresponding to the keyword may be obtained through a parser, and the code corresponding to the keyword is structurally output, thereby converting information used for controlling a large screen in user's voice information into a control instruction capable of controlling the large screen.
Because only part of the voice information collected in the actual use is the control information for expressing and controlling the large screen, and other voice information may be meaningless information such as information consisting of verb aids or word moors, the control information for controlling the large screen can be extracted from the collected voice information through the steps, and the part of the information is converted into the control instruction for controlling the large screen, so that the success rate of obtaining the control instruction is improved, and the time consumed for obtaining the control instruction is reduced compared with the prior art.
The embodiment of the invention provides a control method of a large screen, which comprises the steps of acquiring voice information, converting the voice information into a character string, and acquiring a control instruction according to a keyword matched with characters in the character string in an instruction set, namely extracting information used for controlling the large screen from the voice information of a user and converting the information into the control instruction capable of controlling the large screen.

Specifically, the keyword in the first instruction set may be understood as a control command for instructing to control the display mode of the large screen. Further, the keywords in the first instruction set may include topic keyword, background keyword, and screen keyword, where the topic keyword may be used to indicate a switching action of a topic displayed on the large screen or a topic specifically displayed on the large screen after the topic switching is performed, such as a previous topic, a next topic, a topic name, a topic abbreviation, playing, and stopping; the background class keyword may be used to indicate the switching color of the displayed background of the large screen, e.g. red, blue; the screen class keyword may be used to indicate an overall movement action of the displayed content of the large screen, such as a left movement, a right movement. It should be noted that "previous", "previous topic" and "previous topic" can be considered to indicate the same control command, and in the same way, "next", the "next", "next topic" and "next topic" may be considered to indicate the same control command, the "play" and "play topic" may be considered to indicate the same control command, the "stop" and "stop topic" may be considered to indicate the same control command, the "left shift" and "screen left shift" may be considered to indicate the same control command, the "right shift" and "screen right shift" may be considered to indicate the same control command, the "blue" and "background blue" may be considered to indicate the same control command, and the "red" and "background red" may be considered to indicate the same control command.
204. A second key is determined from the keys of the second instruction set corresponding to the first key.
Wherein the second keyword matches a character in the character string.
Specifically, the keyword in the second instruction set may be understood as a control command for instructing to control the display content of the large screen. Since only a part of the control commands indicated by the keywords in the first instruction set relate to the display content of the control large screen, and the control commands indicated by the keywords in other parts of the first instruction set do not relate to the display content of the control large screen, after the first keyword is determined, the keywords corresponding to the first keyword in the second instruction set, that is, the keywords requiring further matching can be determined, so as to reduce the number of keywords in the further matching process, and match the part of keywords with the characters in the character string, and the keywords capable of being matched with the characters in the character string can be regarded as the second keywords.
Further, the second instruction set may include an index part-of-speech keyword, a chart type class keyword, a dimension part-of-speech keyword, and a time part-of-speech keyword. The index part-of-speech keywords can be used for indicating financial indexes of the content displayed on the large screen, and the index part-of-speech keywords can comprise sales volume, income and gross profit; the chart type key words can be used for indicating icon display modes of contents displayed on a large screen, and the chart type key words can comprise a form, a contrast (a bar chart), a trend (a broken line chart) and a proportion (a pie chart); the dimension part of speech keywords can be used for indicating the province and the brand of the content displayed on the large screen, and can comprise the province and the brand, wherein the province can be a specific province, and the brand can be a specific brand; the time part-of-speech keyword may be used to indicate the time corresponding to the content displayed on the large screen, e.g. the time part-of-speech keyword may be yesterday or today. When the first keyword is a topic keyword, because there may be a further control demand for the display content of the large screen when controlling the topic in the large screen display mode, the keywords in the second instruction set corresponding to the first keyword may include an index part-of-speech keyword, a chart type part-of-speech keyword, a dimension part-of-speech keyword, and a time part-of-speech keyword; when the first keyword is a background keyword or a screen keyword, since there is no need to further control the display content of the large screen when the overall movement of the background displayed on the large screen or the overall content displayed on the large screen is controlled, the keyword corresponding to the first keyword in the second instruction set is null.
205. And acquiring a control instruction according to the first keyword and the second keyword.
Specifically, the obtaining of the control instruction according to the first keyword and the second keyword may be to obtain a first code corresponding to the first keyword and a second code corresponding to the second keyword, and obtain the control instruction according to the first code and the second code.
Because the keywords in the first instruction set and the second instruction set can have corresponding codes, when the control instruction is obtained, the parser can obtain the first code corresponding to the first keyword and the second code corresponding to the second keyword, and the first code and the second code are subjected to structured data output to obtain the control instruction.
Furthermore, after the control instruction is obtained, the webscolet interface can be called to transmit the control instruction, so that the large screen can receive the control instruction through the webscolet interface, and the control instruction is transmitted to the remote control assembly of the large screen. The remote control assembly of the large screen analyzes the transmitted control instruction and controls the display content of the large screen. Specifically, the data can be assembled by configuring the relation between the library configuration and the service library, and the assembled result is rendered by the foreground, so that the single chart can be generated. Wherein the configuration library and the service library. The configuration library stores configuration data such as special subjects, screen division proportion, charts, indexes, dimensionality, corresponding relations of the indexes and the service data and the like. The service library mainly stores service data.
Furthermore, the large screen calls a dividing component to divide the large screen, a resolution algorithm is used for determining the size of a display block according to the resolution of the screen, and then a chart engine is used for filling the content of the block. As shown in fig. 3, the divided large screen 301 may be formed by a plurality of "blocks" to form a "screen", for example, and a plurality of "screens" to form a "topic", and a plurality of "topics" form a large screen display portion. Wherein the "screen" may include a first screen 301 and a second screen 302, and the "tiles" may be topic one 311, topic two 312, time 313, below 314, dimension a315, dimension B316, city-to-ground contrast 317, model proportion 318, trend 319, sales trend 320, histogram one 321, province-to-city sales distribution map 322, histogram two 323, histogram three 324, and histogram four 325.
It should be noted that by dividing the screen into a plurality of "grids," and combining the grids, "blocks," which are basic units for storing contents, can be obtained, so that the coordinates and the number of occupied grids can be stored in the configuration library.
For example, when calculating the position and size of the "tile" on the current screen, the calculation may be performed according to the parameters shown in table 1, and the "tile" may be placed in a configured layout.
TABLE 1
Wherein bw ═ (sw-ew 2)/swn wn + (wn-1) bb
bh＝(sh-eh*2)/shn*hn+(hn-1)*bb；
bt＝for(var i＝y；i>0；i--)，bt+＝twnMap[(jd[y-i])]；
bl＝for(var i＝x；i>0；i--)，bl+＝lwnMap[(jd[x-i])]
nfs＝fs*(sw*sh)/(1900*1600)
According to the width bw of any block ' block X ', the height bh of the block X ', the distance bt of the block X ', the distance left bl of the block X ' and the font size nfs of the current screen, which are obtained by the steps, the position and the size of the block X ' on the current screen can be obtained, and the block X ' is placed according to the configured layout.

The remote control assembly of the large screen analyzes the transmitted control instruction and controls the display content of the large screen. Specifically, the data can be assembled by configuring the relation between the library configuration and the service library, and the assembled result is rendered by the foreground, so that the single chart can be generated. Wherein the configuration library and the service library. The configuration library stores configuration data such as special subjects, screen division proportion, charts, indexes, dimensionality, corresponding relations of the indexes and the service data and the like. The service library mainly stores service data.
Furthermore, the large screen calls a dividing component to divide the large screen, a resolution algorithm is used for determining the size of a display block according to the resolution of the screen, and then a chart engine is used for filling the content of the block. As shown in fig. 3, the divided large screen 301 may be formed by a plurality of "blocks" to form a "screen", for example, and a plurality of "screens" to form a "topic", and a plurality of "topics" form a large screen display portion. Wherein the "screen" may include a first screen 301 and a second screen 302, and the "tiles" may be topic one 311, topic two 312, time 313, below 314, dimension a315, dimension B316, city-to-ground contrast 317, model proportion 318, trend 319, sales trend 320, histogram one 321, province-to-city sales distribution map 322, histogram two 323, histogram three 324, and histogram four 325.
It should be noted that by dividing the screen into a plurality of "grids," and combining the grids, "blocks," which are basic units for storing contents, can be obtained, so that the coordinates and the number of occupied grids can be stored in the configuration library.
For example, when calculating the position and size of the "tile" on the current screen, the calculation may be performed according to the parameters shown in table 1, and the "tile" may be placed in a configured layout.
Wherein bw ═ (sw-ew 2)/swn wn + (wn-1) bb
bh＝(sh-eh*2)/shn*hn+(hn-1)*bb；
bt＝for(var i＝y；i>0；i--)，bt+＝twnMap[(jd[y-i])]；
bl＝for(var i＝x；i>0；i--)，bl+＝lwnMap[(jd[x-i])]
nfs＝fs*(sw*sh)/(1900*1600)
According to the width bw of any block ' block X ', the height bh of the block X ', the distance bt of the block X ', the distance left bl of the block X ' and the font size nfs of the current screen, which are obtained by the steps, the position and the size of the block X ' on the current screen can be obtained, and the block X ' is placed according to the configured layout.
