Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of smart showcases, and in particular to a sensor program display method, device, system and medium. Background Art

[0002] In the prior art, LED display screens have been widely used in various commercial environments, such as advertising and sensor programs. The sensor program data received by the prior art LED display screen generally directly includes the display size, position, program content, picture or path of the sensor program. Different programs have different display sizes and positions. Taking a single sensor as an example, if the pixel area size of the sensor program is 256×256, when centered, if the total width of the text of the sensor program content is 100 and the height is 50, then the prior art calculates the center coordinates (x, y) as follows: x=(area width-program content width) / 2=(256-100) / 2=78; y=(area height-program content width) / 2=(256-50) / 2=103; the image of the sensor program can be drawn according to the position of the starting coordinates (x, y). The display size, position, program content or picture of the existing sensor program is usually stored in a preset file path in the form of a fixed file. These display sizes, positions, program content, pictures or paths have different settings corresponding to the upgrade. Therefore, the upgraded LED display screen may not be able to read or parse the program files before the upgrade, and the LED display screen before the upgrade may not be able to read or parse the program files after the upgrade. Therefore, a sensor program display method is urgently needed to overcome the problem of program playback before and after the upgrade. Summary of the invention

[0039] Embodiment 1

[0040] Figure 1 is a flow chart of a sensor program display method provided by the first embodiment of the present invention. This embodiment can be applied to a sensor program display device for execution. The device can be implemented by software and / or hardware and can generally be integrated into an image display system. Figure 1 As shown, the method includes the following operations:

[0041] S110 , receiving a token stream text corresponding to a display image of a sensor program.

[0042] In one embodiment, the image display system may be an LED display screen. The LED display screen receives the display data of the sensor program before playing the sensor program, and then converts the data into an image format for display. In this embodiment, the display data is sent from the host computer or the sending card via a network cable to a playback box connected to the LED display screen or a receiving card of the LED display screen in the form of a token stream text, or the playback box connected to the LED display screen or the receiving card of the LED display screen receives the token stream text corresponding to the display image from a laptop or mobile phone terminal via a USB interface or WIFI communication.

[0043] S120: Parse the token stream text to obtain drawing instructions and text information.

[0044] In one embodiment, parsing the token stream text includes: traversing the token stream text to identify all character strings, parsing the character strings including preset rules as drawing instructions, and parsing other character strings as text information.

[0045] Specifically, the traversal of the token stream text to identify all character strings includes: converting the text of the received token stream text into numbers according to preset rules to form a token number string; judging whether the token stream text includes a character string of preset rules according to a preset number string order; parsing the character string in the token stream text that meets the preset rules into drawing instructions, and parsing other character strings in the token stream text into text information. In one embodiment, the numbers include at least a first number, a second number, a third number, and a fourth number, and the conversion of the received token stream text into numbers according to the preset rules includes: converting the text in the token stream text into a first number, such as 0, converting the character { in the token stream text into a second number, such as 1, converting the character} in the token stream text into a third number, such as 2, and converting the character $ in the token stream text into a fourth number, such as 3.

[0046] In one embodiment, if the token stream text is: ${HD_ALIGNMENT}current temperature${HD_ARGS}{fontColor=#ff0000}{fontName=SimSun}{fontSize=16}{fontBold=false}{fontItalic=false}{fontUnderline=false}, the converted token digital string is 310000000000000200003100000002100000000000000002100000000000000210000000000000021000000000000000210000000000000000210000000000000000021000000000000000002.

[0047] In one embodiment, the string of the preset rule is ${xxx}, where xxx is any text. The process of judging whether the token stream text includes the string of the preset rule according to the preset sequence of the digital string includes: first checking whether the token stream text matches $ according to the sequence of the digital string, if yes, parsing the token stream text to see if there are one or more {xxx} after $ until the next $ is matched, and after the next $ appears, continuing to parse the token stream text to see if there are one or more {xxx} after $ until the token stream text is traversed. In one embodiment, ${xxx} is identified as an instruction, and the rest is identified as text content. In one embodiment, parsing the string that meets the preset rule in the token stream text as a drawing instruction includes: judging whether {xxx} after $ in the token stream text is a string in the format of {HD_XXX}, and if so, parsing the string as a drawing instruction, and the rest is identified as text content.

[0048] In one embodiment, the drawing instructions include one or more of unsupported instructions, executable instructions, and sensor type instructions, wherein the executable instructions may include format instructions and supplementary instructions.

[0049] In one embodiment, the results of the analysis can be divided into the following situations:

[0050] The first type is an unsupported command, the format is ${HD_XXX}, but because the version is too low, {HD_XXX} XXX cannot be recognized, so it is impossible to parse what specific command it is.

[0051] The second type is executable instructions, which may include format instructions and / or supplementary instructions, such as ${HD_ALIGNMENT} for alignment instructions, ${HD_SPACING} for content spacing instructions, and ${HD_LINE} for line break instructions. ${ARGS}{...}{...} is a supplementary instruction that adds additional parameters to the previous instruction. Supplementary instructions may also be display and hide instructions, index instructions, address text, or any other executable instructions.

[0052] The third type is a sensor type instruction, such as ${HD_Temperature} for a temperature sensor instruction and ${HD_Humidity} for a humidity sensor instruction. In this implementation, the sensor type instruction is a placeholder for sensor parameter information. Preferably, the sensor parameter information is the specific parameter content sensed by the corresponding type of sensor, such as the temperature value sensed by a temperature sensor or the humidity value sensed by a humidity sensor.

[0053] The fourth type is text content. If the parsed result is not any of the above instructions, it is parsed as text content.

[0054] In one embodiment, the token stream text is: "${HD_ALIGNMENT}Current temperature ${HD_ARGS}{fontColor=#ff0000}{fontName=SimSun}{fontSize=16}{fontBold=false}{fontItalic=false}{fontUnderline=false}${HD_ALIGNMENT}{direction=right}${HD_SPACING}{x=6}{y=6}${HD_Temperature}{Unit=1}℃${HD_ARGS}{fontColor=#ff0000}{fontName=SimSun}{fontSize=16}{fontBold=false}{fontItalic=false}{fontUnderline=false}{BindSensorTypeShow=HD_Temperature}${HD_ALIGNMENT}${HD_LINE}${HD_ALIGNMENT}Current humidity${HD_ARGS}{fontColor=#ff0000}{fontName=SimSun}{fontSize=16}{fontBold=false}{fontItalic=false}{fontUnderline=false}${HD_ALIGNMENT}{direction=right}${HD_SPACING}{x=6}{y=6}${HD_Humidity}{Unit=0}%${HD_ARGS}{fontColor=#ff0000}{fontName=SimSun}{fontSize=16}{fontBold=false}{fontItalic=false}{fontUnderline=false}{BindSensorTypeShow=HD_Humidity}"

[0055] According to the above rules, ${HD_ALIGNMENT} indicates that the displayed content starts from the alignment mark, and "Current Temperature" is parsed as text content and is the first content to be displayed. ${HD_ARGS}{fontColor=#ff0000}{fontName=SimSun}{fontSize=16}{fontBold=false}{fontItalic=false}{fontUnderline=false} indicates the font, size, color, bold, underline and other format information of the text content "Current Temperature" when it is displayed. Among them, ${HD_ALIGNMENT}{direction=right} indicates that the displayed content after the first content is right-aligned, and ${HD_SPACING}{x=6}{y=6} indicates the interval x between the second content displayed after the first content and the first content, and the line spacing y between the displayed content and the next line. ${HD_Temperature}{Unit=1}℃ indicates the temperature sensor command and the display unit symbol. Here, the temperature sensor command is the second content to be displayed. ${HD_ARGS}{fontColor=#ff0000}{fontName=SimSun}{fontSize=16}{fontBold=false}{fontItalic=false}{fontUnderline=false} indicates the font, size, color, bold, underline and other format information of the temperature sensor command as the second content. {BindSensorTypeShow=HD_Temperature} indicates that the temperature sensor command will be displayed only when the specific parameter content is received, otherwise the display content will be blocked. ${HD_ALIGNMENT}${HD_LINE} indicates alignment and line break. {HD_ALIGNMENT} Current humidity means that the content displayed after the line break starts from the alignment mark, "Current humidity" is parsed as text content and used as the third content to be displayed after the line break. ${HD_ARGS}{fontColor=#ff0000}{fontName=SimSun}{fontSize=16}{fontBold=false}{fontItalic=false}{fontUnderline=false} indicates the font, size, color, bold, underline and other format information of the text content "Current humidity" when it is displayed. ${HD_ALIGNMENT}{direction=right}${HD_SPACING}{x=6}{y=6} indicates the interval x between the fourth content displayed after the line break and the third content in front, and the line spacing y with the next line,

[0056] ${HD_Humidity}{Unit=0}%$ represents the humidity sensor instruction and the display unit symbol. Here, the humidity sensor instruction is the fourth content to be displayed. {HD_ARGS}{fontColor=#ff0000}{fontName=SimSun}{fontSize=16}{fontBold=false}{fontItalic=false}{fontUnderline=false} represents the font, size, color, bold, underline and other format information displayed as the fourth content of the humidity sensor instruction. {BindSensorTypeShow=HD_Humidity} means that the humidity sensor instruction will be displayed only after receiving the specific parameter content, otherwise the display content will be blocked.

[0057] In one embodiment, when the temperature sensor instruction receives a parameter of 26 and the humidity sensor instruction receives a parameter of 70, the content displayed on the display screen 210 according to the above analysis result is as follows: Figure 2 As shown, Figure 2 The center alignment mark may include a left alignment mark 221 and a right alignment mark 222 .

[0058] S130, generating a program image according to the sensor parameter information, the drawing instruction and the text information;

[0059] In this embodiment, the sensor parameter information is the specific parameter content received corresponding to the sensor type instruction, that is, the specific parameter value detected by the sensor. These specific parameter values ​​are stored in the preset parameter information path in the form of a document and updated in real time according to the detection frequency of the sensor. In the above embodiment, the parameter information path can be specified or modified by the instruction ${HD_ARGS}{fikeKey=key1}, that is, modifying the index value key1 of the parameter information path, so that when upgrading later, you only need to replace the index value key1 or replace the corresponding specific parameter document to be compatible with the old version. In an alternative embodiment, the index value of the parameter information path can be confirmed by determining which text stream the current token stream text is, such as: SensorTokenStream1, SensorTokenStream2, these two text streams correspond to the index of the temperature parameter information path and the humidity parameter information path respectively.

[0060] In one embodiment, multiple token stream texts are received. After each token stream text is parsed, the appearance or format of the sensor parameter information and / or text information is adjusted according to the obtained executable instructions for format adjustment to generate a sub-image to be displayed for each token stream text, and then the sub-images to be displayed corresponding to all token stream texts are merged and drawn into an image to be displayed.

[0061] In an alternative embodiment, after obtaining all the token stream texts, the image to be displayed is drawn once in a loop in the aforementioned manner and a drawing template is formed. The appearance or format of each text message is adjusted according to the executable instructions for format adjustment obtained to generate the corresponding first image. The first images corresponding to the relevant text information are pre-loaded. When drawing the complete image to be displayed, the drawing is performed in the order of the corresponding instructions of the token stream text. If it is a sensor instruction, the corresponding sensor parameter information is obtained and the second image is drawn at the corresponding position of the drawing template. If it is text information, the first image loaded at the corresponding position on the drawing template is directly drawn. After each loop, a frame of the image to be displayed is generated on the drawing template. If there is no other content to be displayed, the program image can be generated according to the image to be displayed. If there are other images to be displayed, the image to be displayed and the other images to be displayed are merged to generate each frame of the program image.

[0062] S140, sending the program image to the LED display screen for display.

[0063] In this embodiment, the program image is encoded and sent to the LED screen for display. In this embodiment, the program image encoding can be appropriately scaled according to the resolution of the LED display screen, or the brightness or chromaticity of the program image can be adjusted according to the brightness of the environment.

[0064] Compared with the prior art, the embodiment of the present invention adopts token stream text to transmit display image data, so the data transmission of the content displayed by the sensor program is more convenient and flexible, and the format adjustment of the display content is also more convenient. There will be no problems of display information loss or image loading failure due to upgrades such as changing the storage path, increasing the display content, and increasing the sensor type. By parsing the drawing instructions of the token stream text, various formats of drawings can be directly implemented, and the number of displayed sensor programs can be increased arbitrarily, which reduces the problem of software incompatibility caused by hardware upgrades and achieves the effect that program playback is not easily affected by upgrades.

[0066] Figure 3300 is a schematic diagram of the structure of a sensor program display device provided in the second embodiment of the present invention. The device 300 can be implemented by software and / or hardware, and can generally be integrated into an image display system, such as Figure 3 As shown, the device 300 includes a data receiving module 310 , a data parsing module 320 , an image generating module 330 and an image sending module 340 .

[0067] The data receiving module 310 is used to receive the token stream text corresponding to the display image of the sensor program.

[0068] In one embodiment, the image display system may be an LED display screen. The LED display screen receives the display data of the sensor program before playing the sensor program, and then converts the data into an image format for display. In this embodiment, the display data is sent from the host computer or the sending card via a network cable to a playback box connected to the LED display screen or a receiving card of the LED display screen in the form of a token stream text, or the playback box connected to the LED display screen or the receiving card of the LED display screen receives the token stream text corresponding to the display image from a laptop or mobile phone terminal via a USB interface or WIFI communication.

[0069] The data parsing module 320 is used to parse the token stream text to obtain drawing instructions and text information.

[0070] Optionally, the data parsing module 320 further includes a text parsing module for parsing the token stream text. Specifically, the text parsing module traverses the token stream text to identify all character strings, parses the character strings including preset rules into drawing instructions, and parses other character strings into text information.

[0071] Optionally, the text parsing module includes a text conversion module, a character judgment module and an instruction generation module. The text conversion module is used to convert the text of the received token stream text into numbers according to preset rules to form a token number string; the character judgment module is used to judge whether the token stream text includes a character string of preset rules according to a preset number string sequence. The instruction generation module is used to parse the character string in the token stream text that meets the preset rules into a drawing instruction, and parse other character strings in the token stream text into text information.

[0073] Optionally, the string of the preset rule is ${xxx}, where xxx is any text, and the character judgment module is further used to first check whether the token stream text matches $ according to the order of the digital string, and if so, parse the token stream text to see whether there are one or more {xxx} after $ until the next $ is matched. After the next $ appears, continue to parse the token stream text to see whether there are one or more {xxx} after $ until the token stream text is traversed.

[0074] Optionally, the character judgment module is further used to judge whether {xxx} after $ in the token stream text is a string in the format of {HD_XXX}, and if so, the string can be parsed as a drawing instruction.

In one embodiment, if the token stream text is: ${HD_ALIGNMENT} current temperature ${HD_ARGS}{fontColor=#ff0000}{fontName=SimSun}{fontSize=16}{fontBold=false}{fontItalic=false}{fontUnderline=false}, the converted token digital string is 3100000000000002000031000000021000000000000000002100000000000000210000000000000021000000000000000021000000000000000002. In this embodiment, converting the token digital string into a digital string and then performing rule recognition can reduce the amount of data storage and speed up the calculation.

[0076] In one embodiment, the character string of the preset rule is ${xxx}, where xxx is any text. The step of judging whether the token stream text includes the character string of the preset rule according to the preset sequence of the digital string includes: first checking whether the token stream text matches $ according to the sequence of the digital string, and if so, parsing the token stream text to see whether there are one or more {xxx} after $ until the next $ is matched, and after the next $ appears, continuing to parse the token stream text to see whether there are one or more {xxx} after $ until the token stream text is traversed.

[0077] In one embodiment, ${xxx} is recognized as an instruction, and the rest is recognized as text content. In one embodiment, the character string in the token stream text that meets the preset rules is parsed as a drawing instruction, including: determining whether {xxx} after $ in the token stream text is a character string in the format of {HD_XXX}, and if so, the character string can be parsed as a drawing instruction, and the rest is recognized as text content.

[0078] In one embodiment, the drawing instructions include one or more of unsupported instructions, executable instructions, and sensor type instructions, wherein the executable instructions may include format instructions and supplementary instructions.

[0079] The results of the analysis can be divided into the following situations:

[0080] The first type is unsupported instructions, the format is ${HD_XXX}, but because the version is too low, {HD_XXX} cannot be parsed into what specific instruction it is.

[0081] The second type is executable instructions, which may include format instructions, such as ${HD_ALIGNMENT} for alignment instructions, ${HD_SPACING} for content spacing instructions, and ${HD_LINE} for line break instructions. ${ARGS}{...}{...} is a supplementary instruction that adds additional parameters to the previous instruction. The supplementary instruction can be a display and hide instruction, an index instruction, an address text, or any executable instruction.

[0082] The third type is a sensor type instruction, such as ${HD_Temperature} for a temperature sensor instruction and ${HD_Humidity} for a humidity sensor instruction. In this implementation, the sensor type instruction is a placeholder for sensor parameter information. Preferably, the sensor parameter information is the specific parameter content sensed by the corresponding type of sensor, such as the temperature value sensed by a temperature sensor or the humidity value sensed by a humidity sensor.

Here, the humidity sensor instruction is the fourth content to be displayed. {HD_ARGS}{fontColor=#ff0000}{fontName=SimSun}{fontSize=16}{fontBold=false}{fontItalic=false}{fontUnderline=false} indicates the font, size, color, bold, underline and other format information of the humidity sensor instruction displayed as the fourth content. {BindSensorTypeShow=HD_Humidity} indicates that the humidity sensor instruction is displayed only when the specific parameter content is received, otherwise the display content is blocked.

[0086] The image generation module 330 is used to generate a program image according to the sensor parameter information, the drawing instruction and the text information.

[0087] When the temperature parameter value received corresponding to the temperature sensor instruction is 26, and the humidity parameter received corresponding to the humidity sensor instruction is 70, the content displayed on the display screen 210 according to the above analysis results is as follows: Figure 2 As shown, Figure 2 The center alignment mark may include a left alignment mark 221 and a right alignment mark 222 .

[0088] In this embodiment, the sensor parameter information is the specific parameter content received corresponding to the sensor type instruction, that is, the specific parameter value detected by the sensor. These specific parameter values ​​are stored in the preset parameter information path in the form of a document and updated in real time according to the detection frequency of the sensor. In the above embodiment, the parameter information path can be specified or modified by the instruction ${HD_ARGS}{fikeKey=key1}, that is, modifying the index value key1 of the parameter information path, so that when upgrading later, you only need to replace the index value key1 or replace the corresponding specific parameter document to be compatible with the old version. In an alternative embodiment, the index value of the parameter information path can be confirmed without an instruction, but by determining which text stream the current token stream text is to update and confirm the index value of the parameter information path, such as: SensorTokenStream1, SensorTokenStream2, these two text streams correspond to the index of the temperature parameter information path and the humidity parameter information path respectively.

[0089] In one embodiment, multiple token stream texts are received. After each token stream text is parsed, the appearance or format of the sensor parameter information and / or text information is adjusted according to the obtained executable instructions for format adjustment to generate a sub-image to be displayed for each token stream text, and then the sub-images to be displayed corresponding to all token stream texts are merged and drawn into an image to be displayed.

[0090] In an alternative embodiment, after obtaining all the token stream texts, the image to be displayed is drawn once in a loop in the aforementioned manner and a drawing template is formed. The appearance or format of each text message is adjusted according to the executable instructions for format adjustment obtained to generate the corresponding first image. The first images corresponding to the relevant text information are pre-loaded. When drawing the complete image to be displayed, the drawing is performed in the order of the corresponding instructions of the token stream text. If it is a sensor instruction, the corresponding sensor parameter information is obtained and the second image is drawn at the corresponding position of the drawing template. If it is text information, the first image loaded at the corresponding position on the drawing template is directly drawn. After each loop, a frame of the image to be displayed is generated on the drawing template. If there is no other content to be displayed, the program image can be generated according to the image to be displayed. If there are other images to be displayed, the image to be displayed and the other images to be displayed are merged to generate each frame of the program image.

[0091] In one embodiment, the image sending module 340 is used to send the program image to the LED display screen for display. Specifically, the program image can be encoded and sent to the LED screen for display. In this embodiment, the encoding of the program image can be appropriately scaled according to the resolution of the LED display screen, or the brightness or chromaticity of the program image can be adjusted according to the brightness of the environment.

[0092] In this embodiment, the above-mentioned sensor program display device can execute the sensor program display method provided in any embodiment of the present invention, and has the functional modules and beneficial effects corresponding to the execution method. For the technical details not described in detail in this embodiment, please refer to the sensor program display method provided in any embodiment of the present invention.
