In this embodiment, the vehicle-mounted atmosphere lamp combined display control method includes the following steps:
step S10: detecting messages in a CAN bus of the whole vehicle;
it should be noted that the execution main body of the embodiment is the first atmosphere lamp, wherein the first atmosphere lamp has functions of data processing, data communication, program operation and the like, and the first atmosphere lamp is an atmosphere lamp connected with the entire vehicle CAN bus in an atmosphere lamp panel in which a plurality of atmosphere lamps are arranged in a strip shape.
It CAN be understood that each atmosphere lamp is controlled by an independent MCU chip, and each atmosphere lamp is connected to a storage medium, for example, a flash memory chip, a ROM memory, a RAM memory, or other memories with data storage functions, preferably, a flash memory chip, where the MCU of the first atmosphere lamp is configured to connect the first path of CAN bus of the MCU to the CAN bus of the entire vehicle, and the remaining multiple paths of CAN buses are connected to the CAN interfaces of other atmosphere lamps.
Step S20: when the message is detected to be a display message, identifying the display message to obtain a content tag of the content to be displayed, and sending the content tag to each second atmosphere lamp, wherein the first atmosphere lamp is connected with each second atmosphere lamp through a CAN bus;
it should be noted that the display message refers to one of messages in the CAN bus, and is an instruction for instructing the first ambience lamp and each second ambience lamp to display designated display content, where the content to be displayed refers to an animation or a picture that needs to be displayed on the ambience lamp, and the content to be displayed is stored in a storage medium of each ambience lamp.
It can be understood that the content tag is contained in the display message, when the display message is detected by the first atmosphere lamp, the display message is identified and then extracted from the display message, and the content tag has a corresponding relationship with the picture or animation stored in the storage medium, so that the content to be displayed can be accurately positioned according to the content tag.
It should be understood that the second atmosphere lamp refers to other atmosphere lamps on the current elongated atmosphere lamp panel besides the first atmosphere lamp, the number of the second atmosphere lamps is not exclusive and may be one or more, and the second atmosphere lamp is connected with the first atmosphere lamp through the CAN bus for receiving the information transmitted by the first atmosphere lamp.
In specific implementation, the content to be displayed is prepared in advance before the atmosphere lamp performs image display, referring to fig. 3, and fig. 3 is an atmosphere lamp animation display flow chart, the content to be displayed first passes through an animation segment data providing unit, a video animation or picture with a small resolution and a large width is divided into several independent segment files according to the length of the automobile body and the width of each atmosphere lamp on the automobile body, and each segment animation maintains the original frame rate and duration. And packaging the obtained segmented files into binary bin files, sequentially burning the binary bin files into flash memory chips of the atmosphere lamps, converting the packed bin files into LED data which can be used by the corresponding atmosphere lamps by an animation synchronization unit and a data conversion calculation unit, and finally displaying the current content to be displayed by an animation display unit.
The first atmosphere lamp can receive the message signals from the whole vehicle in real time and detect the received message signals, and the messages which need to be received by the first atmosphere lamp can be identified according to different identification information on different messages because different message signals have different identification information. When the first atmosphere lamp detects a display message for controlling the atmosphere lamp to start displaying, the currently obtained display message is firstly identified, a content label of the content to be displayed is read from the display message, and after the content label of the content to be displayed is obtained, the content label is transmitted to each second atmosphere lamp through the CAN bus.
Step S30: and generating a synchronization instruction, sending the synchronization instruction to each second atmosphere lamp, enabling the first atmosphere lamp and each second atmosphere lamp to generate a display strategy according to the content label, and displaying the content to be displayed corresponding to the content label according to the display strategy at the synchronization time corresponding to the synchronization instruction.
It should be noted that the synchronization instruction refers to a synchronization instruction generated after the first ambience lamp receives the display message in the entire vehicle CAN message, and needs to be generated according to the to-be-displayed content tag in the display message and the current time, the synchronization instruction may be used to cause the first ambience lamp and each second ambience lamp to display the to-be-displayed content according to the synchronization instruction, and the synchronization instruction may include the first ambience lamp or each second ambience lamp to be displayed, the content tag of the to-be-displayed content, the display time, the display mode, and the like, and may also include other contents.
It should be understood that the display strategy refers to the display modes of the first atmosphere lamp and each second atmosphere lamp, the display strategy comprises the display time of the first atmosphere lamp and each second atmosphere lamp and the content to be displayed, and the MCU of the atmosphere lamp receiving the synchronization strategy can generate the display mode according with the content to be displayed according to the content to be displayed.
It CAN be understood that the synchronous time refers to a fixed time at which the first ambience lamp or each second ambience lamp agrees to display the content to be displayed, the display time is generated by the MCU of the first ambience lamp and transmitted to each second ambience lamp through the CAN bus connected to the CAN interfaces of the first ambience lamp and each second ambience lamp, and the time period between two display times is the display time of each frame of the content to be displayed.
It should be noted that the content to be displayed is content to be displayed on the first ambience lamp and each second ambience lamp, the content to be displayed may be a picture or an animation, each content to be displayed has a unique content tag, the first ambience lamp and each second ambience lamp acquire the content to be displayed from the storage medium respectively connected to the first ambience lamp and each second ambience lamp according to the received content tag, the content to be displayed on each ambience lamp may be burned into the corresponding storage medium in advance to ensure that the display content can be read quickly, or the content to be displayed may be acquired in the cloud after the content tag is received.
In the specific implementation, the first atmosphere lamp generates a synchronization instruction according to the detected display message, the generated synchronization instruction is sent to the first atmosphere lamp and each second atmosphere lamp, when the first atmosphere lamp and each second atmosphere lamp receive the synchronization instruction for the first time, the first atmosphere lamp and each second atmosphere lamp search for corresponding content to be displayed in the flash memory chip according to a content tag in the synchronization instruction and directly load a first frame of the content to be displayed in the flash memory chip, the first atmosphere lamp and each second atmosphere lamp recognize the synchronization instruction, the synchronization time for displaying the content to be displayed on the atmosphere lamps is recognized, and the synchronous display of each atmosphere lamp is completed at the synchronization time.
For example, the information contained in the display message is the content to be displayed with the display content tag of 01, at this time, the first ambience lamp will package the 01 tag information in the synchronization command, and then attach the synchronization time, so that each ambience lamp can finish displaying at the same time, for example, the current synchronization command is agreed at the time of 10:46:25.765, when the time arrives, the ambience lamp which needs to display the content to be displayed needs to complete the display of the content to be displayed at the time, after the display of the current content is completed, the display of the next content is completed after a preset time interval, in order to make the first ambience lamp and each second ambience lamp synchronously display, therefore, the time for each content to last may be appointed, after the time finishes, the next round of display is started, and the next content data loading is completed within the waiting time, assuming the time interval is 20 milliseconds, the next content may be displayed at a time of 10.785, and this time is the next synchronization instruction sent by the first ambience lamp after the current synchronization instruction, i.e. the synchronization instruction only sends the display time for which the synchronization starts according to the preset time interval instead of sending the synchronization instruction at the preset time interval, and after each second ambience lamp receives the synchronization instruction, even if each second ambience lamp has received the synchronization instruction, the next content does not start to be displayed when the current time does not reach the synchronization time indicated by the synchronization instruction.
The embodiment detects the message in the CAN bus of the whole vehicle; when the message is detected to be a display message, identifying the display message to obtain a content tag of the content to be displayed, and sending the content tag to each second atmosphere lamp, wherein the first atmosphere lamp is connected with each second atmosphere lamp through a CAN bus; and generating a synchronization instruction, sending the synchronization instruction to each second atmosphere lamp, enabling the first atmosphere lamp and each second atmosphere lamp to generate a display strategy according to the content label, and displaying the content to be displayed corresponding to the content label according to the display strategy at the synchronization time corresponding to the synchronization instruction. According to the invention, through message detection in the CAN bus of the whole vehicle, when the message is detected to be displayed, the first atmosphere lamp sends a synchronous instruction to the first atmosphere lamp and each second atmosphere lamp, so that the first atmosphere lamp and each second atmosphere lamp display the content to be displayed at the appointed moment. The method and the device realize that all atmosphere lamps can simultaneously display the content to be displayed, and avoid the technical problem that the display effect is not synchronous because each atmosphere lamp receives the message with time difference.
Referring to fig. 4, fig. 4 is a flowchart illustrating a second embodiment of a vehicle-mounted atmosphere lamp joint display control method according to the present invention.
Based on the first embodiment, in the step S30, the method for controlling the vehicle-mounted ambience light joint display further includes:
step S301: searching for corresponding content to be displayed according to the content tag;
step S302: determining a display label of a second atmosphere lamp needing to participate in display according to the content to be displayed;
step S303: and obtaining the display strategies of the first atmosphere lamp and the second atmosphere lamp participating in the display according to the content label and the display label.
It should be noted that the display tag refers to an identification tag of the second ambience lamp, and is used to determine which of the plurality of second ambience lamps needs to perform the display operation.
In the specific implementation, firstly, the content to be displayed is determined according to a corresponding relation table between the content tag and the content to be displayed, the corresponding relation table between the content tag and the content to be displayed is preset, for example, the current content tag is 10, at this time, the content to be displayed corresponding to the content tag 10 needs to be found in the corresponding relation table according to the content tag 10, and it is assumed that the current content to be displayed is a relatively short animation video, therefore, it needs to be determined according to the content to be displayed that several atmosphere lamps need to be displayed, for example, the current animation video needs 5 atmosphere lamp panels to be displayed, and then 5 continuous atmospheres in the second atmosphere lamp, for example, lamp panels 01 to 05, are specified in the synchronization instruction according to the first atmosphere lamp to complete animation display.
Before the display process of the lamp panel display tag 01-05, the synchronization instruction sent by the first atmosphere lamp is received and identified, and the first frame of the animation video with the serial number of 10 stored in the flash memory chip of the lamp panel 01-05 is preloaded, so that the display of the currently loaded frame of the content to be displayed is completed at the synchronization time appointed in the synchronization instruction.
In order to further obtain the display strategy, the method also comprises the following steps:
obtaining a corresponding two-dimensional RGB value array according to the current content frame data;
and obtaining a display strategy according to the corresponding two-dimensional RGB value array.
It should be noted that a content frame refers to frame data of a picture and animation frame data of an animation in the content to be displayed, and is an image picture of a minimum unit, one frame is a still picture, and a two-dimensional RGB value array refers to a composition and a ratio of red, green, and blue colors required for forming the frame in current frame data, so as to form colors and patterns in the content to be displayed.
In the specific implementation, according to a picture in a frame to be displayed of content to be displayed, the picture is identified, an RGB value corresponding to each pixel point in the frame is obtained, the RGB is recorded, a series of obtained RGB recorded values are arranged in the same arrangement mode as the pixel points to form a two-dimensional RGB array, the position in the array corresponds to the pixel point position in the frame data, and then the obtained two-dimensional RGB value array is applied to the atmosphere lamp panel, so that the atmosphere lamp panel performs picture display according to the two-dimensional RGB data.
In order to further synchronize the display strategy to each LED lamp, the following steps are included:
determining LED lamps in the first atmosphere lamp and the second atmosphere lamp participating in display according to the two-dimensional RGB value array;
and setting display strategies of the LED lamps in the first atmosphere lamp and the second atmosphere lamp participating in display according to the two-dimensional RGB value group.
In the specific implementation, a two-dimensional RGB value array obtained according to the content to be displayed is processed first, and is corresponding to the positions of the LED lamps in the ambient lamp, in an actual situation, the number of the LED lamps may be less than the number of pixels or the number of values corresponding to the two-dimensional RGB value array, so that the two-dimensional RGB value array needs to be transformed when the two-dimensional RGB value array corresponds to the LED lamps, for example, if the data amount in the current two-dimensional RGB value array is four times the number of the LED lamps in the ambient lamp, a moving block with a size of 2 × 2 may be constructed in the two-dimensional RGB, and the moving step length of the moving block is 2, at this time, the RGB values in the moving block with the size of 2 × 2 are processed, each 4 RGB value is converted into 1 RGB value, so that the data is reduced by 4 times, the reduction degree of the content to be displayed is ensured as much as possible, and then a new two-dimensional RGB value array reduced by 4 times is corresponding to the LED lamps in the ambient lamp, and the color display of the ambient lamp is realized, thereby displaying the image on the ambient lamp.
In order to further complete the synchronous display of the content to be displayed on the atmosphere lamp, the method further comprises the following steps after obtaining the display strategy according to the corresponding two-dimensional RGB value array:
and loading next content frame data, and decoding the next frame data to obtain a two-dimensional RGB value array corresponding to the next frame data.
It should be noted that the next content frame data refers to a content frame that is sequentially after the currently displayed content frame, and the next content frame is ready to be displayed after the current content frame is completely displayed.
It should be noted that the content frame data refers to a single image picture obtained by splitting a complete content to be displayed into one frame and one frame.
In the specific implementation, when the current content frame has reached the synchronization moment and the content display of the current frame is completed on the LED lamp, the current atmosphere lamp loads the next content frame of the current content to be displayed in the flash memory chip, and when the current content frame is subjected to LED display, completes the loading and decoding processing of the next content frame, so as to obtain the two-dimensional RGB value array of the next content frame, and matches the two-dimensional RGB value array of the next content frame with the LED, so as to obtain the two-dimensional RGB value array of the next content frame.
In order to further obtain a corresponding two-dimensional RGB value array according to the current content frame data, the method further comprises the following steps:
splitting the content to be displayed to obtain content frame data of the content to be displayed;
detecting the current content frame, and when the detection result is a first content frame, obtaining a corresponding two-dimensional RGB value array according to the first content frame, and loading a next content frame;
and decoding the next content frame to obtain a two-dimensional RGB value array corresponding to the next content frame.
It should be noted that splitting the content to be displayed refers to dividing a complete content to be displayed into image pictures with frames as units, where each split frame is called a content frame, and when splitting, the content to be displayed needs to be split according to different frame numbers according to a specific application scenario.
In a specific implementation, an obtained content to be displayed is split into a plurality of content frames meeting actual requirements, the adopted strategies are different according to different current frame numbers, and before processing, the current frame number needs to be detected, for example, assuming that the current content frame is detected to be a first frame, at this time, when the first frame is processed, a two-dimensional RGB value array is first generated by matching the first frame, after the two-dimensional RGB value array of the first frame is obtained, the content of a second frame is immediately obtained, and the content of the second frame is simultaneously decoded, that is, when the content of the first frame is displayed, two-frame content frame data needs to be processed, and when it is detected that the current frame is not the first frame, a next content frame is loaded after the current frame is processed, and a corresponding two-dimensional RGB value array is generated according to the content of the next frame.
In order to further complete the synchronous display of the contents to be displayed, the method further comprises the following steps:
