Detailed Description
In order to make the objects, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application are clearly and completely described, and it is obvious that the embodiments described below are only a part of the embodiments of the present application, and not all 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 application.
Referring to fig. 1, fig. 1 is a flowchart of an information source channel intercommunication transmission method of an intelligent photo frame according to the present application.
A first aspect of the embodiments of the present application provides an intelligent photo frame information source channel intercommunication transmission method, including the following steps:
s1: monitoring potential parameters and interface parameters of an information source interface, judging whether the information source interface is an effective information source interface according to the duration of the potential parameters, and judging the type of the effective information source interface according to the interface parameters;
s2: receiving image data from a cloud, acquiring attribute parameters of the image data received by the effective information source interface, and screening the effective information source interface according to the attribute parameters to obtain an intercommunication interface;
s3: and receiving a synchronous signal to connect the intercommunication interface with the equipment, and selecting a preset channel intercommunication model according to the type of the effective information source interface to distribute and transmit the image data from the equipment in the intercommunication interface.
It should be noted that, the currently available effective information source interface is searched through the potential parameter, and the type of the interface is judged through the interface parameter, such as a homologous information source or a heterologous information source, so as to obtain the transmission form of the current information source, adaptively establish an information source switching channel intercommunication scheme, and optimize a channel intercommunication program. The intercommunication interfaces are screened according to the transmission performance of the effective information source interfaces analyzed according to the receiving condition of the image data from the cloud end, so that resources can be utilized to the maximum extent. The synchronization signal is a Vsync (Vertical Sync) Vertical synchronization signal, which is a rendering option for a video card. This option prevents the video card from altering the display memory until the monitor completes the current refresh cycle. When the vertical synchronization is applied, if the generated frame rate is higher than the refresh rate of the monitor, the presentation engine matches the maximum refresh rate of the monitor, when the SWITCH of the corresponding interface is started after the intercommunication interface is connected with the device, the image data is distributed and transmitted in the intercommunication interface according to the preset channel intercommunication model, the image data transmission efficiency is accelerated, and the loading time is greatly shortened.
According to the embodiment of the application, the monitoring of the potential parameters of the information source interface is specifically as follows:
if the information source interface is a VGA interface, the potential parameter is a high level parameter and a low level parameter of a pin SCL;
and if the information source interface is an HDMI interface, the potential parameters are high level parameters and low level parameters of the pins TMDS.
It should be noted that, when the source interface is a VGA interface, by monitoring the variation of the high and low levels of the SCL pin on the VGA interface, where the high level 3.3V lasts 20ms and the low level 1.3V lasts 10ms, it is determined as a valid source interface (assuming that the number of the interfaces is 5, V01, V02, V03, V04, and V05). When the source interface is an HDMI interface, the source interface is determined to be an effective source interface (assuming that the number of the interfaces is 10 in total from H01 to H10) by monitoring the change of the high and low levels of a TMDS pin on the HDMI interface, wherein the high level is 5.5V for 20ms, and the low level is 1.7V for 10 ms.
According to the embodiment of the present application, the determining the type of the effective information source interface according to the interface parameter specifically includes:
identifying the interface parameters of the effective information source interface and counting the type and the number of the interface parameters;
and judging the type of the effective information source interface to be a homologous interface or a heterologous interface according to the type and the number of the interface parameters.
It should be noted that the interface parameters include an interface data type, an interface model, and the like, and are used to distinguish interface types, such as VGA and HDMI. If only one type of effective source interface exists, the source interface is determined to be the same source interface, namely the type of the interface before the source channel is switched is consistent with that after the source channel is switched. If the types of the effective information source interfaces are more than one, the effective information source interfaces are determined to be different interfaces, namely the types of the interfaces before and after the information source channel is switched are different.
According to the embodiment of the application, the step of screening the effective information source interface according to the attribute parameters to obtain the interworking interface specifically comprises the following steps:
if the information source interface is a VGA interface, the attribute parameter is a frame rate value, and the intercommunication interface is obtained by screening according to a preset threshold value of the frame rate value;
and if the information source interface is an HDMI interface and the attribute parameter is a pixel value, screening according to a preset threshold value of the pixel value to obtain the intercommunication interface.
It should be noted that, when the source interface is a VGA interface, the frame rate value can be used to screen the interworking interface, for example, the cloud end sends a photo, and the VGA interface receives the photo, at this time, the frame rate value of V01 is 60hz, the frame rate value of v02 is 10hz, the frame rate value of v03 is 5hz, the frame rate value of v04 is 120hz, and the frame rate value of v05 is 80HZ. And then calculating the number (3) and interface numbers (V01, V04 and V05) of VGA interfaces with the same frame rate value of more than 60HZ, which are received by 5 different VGA interfaces. Similarly, when the source interface is an HDMI interface, the interworking interfaces can be filtered by using the pixel values, for example, the pixel values of the pictures of H01-H10 are read, and the number (3) of the HDMI interfaces and the interface numbers (H02, H03, and H06) of the same picture with the pixel value greater than 1K received by 10 different HDMI interfaces are calculated.
According to the embodiment of the application, selecting the preset channel intercommunication model according to the type of the effective information source interface specifically comprises the following steps:
if the type of the effective information source interface is a homologous interface, selecting a preset homologous channel intercommunication model, and distributing image data from the equipment to all the intercommunication interfaces from the initial interface for transmission according to the homologous channel intercommunication model;
if the type of the effective information source interface is a heterogeneous source interface, selecting a preset heterogeneous channel intercommunication model, starting heterogeneous channel intercommunication by controlling the working state of pins of the intercommunication interface according to the heterogeneous channel intercommunication model, and distributing image data from the equipment to all heterogeneous channel interfaces from an initial interface for transmission.
It should be noted that the initial interface is the only source interface (assumed as V01) that is defaulted for data transmission after accessing the device. If the source channel is switched, the data volume of the image data is averagely distributed to two interfaces V04 and V05 from V01 by using the same-source channel intercommunication model for data transmission, so that the time of V01 blockage is saved, and the transmission rate of the same-source channel is accelerated. Similarly, assuming that the initial interface is H02, the data size of the image data is averagely allocated to the H03 and H06 interfaces for transmission. If the default initial interface is used for data transmission, for example, the time for transmitting data by the H02 interface is 5S, while the time for transmitting data after being distributed by the homologous channel interworking model can be shortened to 3S. If the source channel is switched from the different source channel, the data volume of the image data is averagely distributed to the interfaces H02, H03 and H06 for transmission by using the intercommunication model of the different source channel. For example, the time taken for data transmission of the V01 interface is 5S originally, and after the data is distributed to H02, H03 and H06 by using the heterogeneous channel intercommunication model, the time taken for data transmission can be shortened to 1S.
According to the embodiment of the application, starting the heterogeneous channel intercommunication by controlling the working state of the pin of the intercommunication interface specifically comprises the following steps:
if the initial interface is an HDMI interface, controlling a pin TMDS-DATA1, a pin TMDS-DATA2 and a pin TMDS-DATA3 of the HDMI interface to be dormant, and controlling a pin CLK to work;
and if the initial interface is a VGA interface, controlling the pins R, G and B of the VGA interface to be dormant, and controlling the receiving pins of line synchronization and field synchronization to work.
It should be noted that, when the HDMI interface in the smart photo frame allocates transmission data to the VGA interface, the TMDS pin in the HDMI interface can be controlled to sleep, and the sleep duration can be set to 6s. When the VGA interface in the intelligent photo frame distributes transmission data to the HDMI interface, the dormancy of the pins R, G and B in the VGA interface can be controlled, and the dormancy duration can be set to 6s. In the heterogeneous data transmission, one pin of the interface is dormant, and other pins work to realize channel intercommunication information and accelerate the data transmission speed.
According to the embodiment of the present application, after receiving a synchronization signal to connect the interworking interface with a device, before selecting a preset channel interworking model according to the type of the effective information source interface, the method further includes:
analyzing the data volume of the image data of the equipment, and acquiring the attribute parameters of the image data received by an initial interface;
and judging whether the data volume of the image data of the equipment exceeds the data volume parameter in the attribute parameters of the image data received by the initial interface, if so, starting the preset channel intercommunication model, and if not, forbidding the preset channel intercommunication model.
It should be noted that the data amount of the image data represents the size attribute of the image data, and can be generally expressed as the product of the frame rate and the duration, i.e. the total frame number, where the attribute parameters can include parameter information such as the frame rate and the duration used, and the data amount parameter in the attribute parameters can also be expressed as the product of the frame rate and the default unit duration (e.g. 60HZ, 1 min). Whether the transmission time length of the current initial interface can be controlled within the default time length is judged according to the data volume of the image data to be transmitted, and then the information source channel intercommunication process is started selectively, so that the transmission pressure can be distributed when the data volume is large, and the data processing speed can be ensured when the data volume is small.
According to the embodiment of the present application, after receiving a synchronization signal to connect the interworking interface with a device, before selecting a preset channel interworking model according to the type of the effective information source interface, the method further includes:
analyzing the data volume of the image data of the equipment, and acquiring the attribute parameters of the image data received by an initial interface;
generating the priority of each intercommunication interface according to the attribute parameters of the image data received by the effective information source interface;
setting the starting number of the intercommunication interfaces in the preset channel intercommunication model according to the multiple relation between the data quantity of the image data of the equipment and the data quantity parameter in the attribute parameter of the image data received by the initial interface;
and setting the starting sequence of the intercommunication interfaces in the preset channel intercommunication model according to the priority of the intercommunication interfaces.
It should be noted that determining the number of enabled interworking interfaces by using the multiple relationship between the image data amount and the data amount parameter of the interface attribute parameter may facilitate the image data to be completed within a default time duration, for example, the ratio of the image data amount to the data amount parameter of the attribute parameter is 2, and the number of enabled interworking interfaces is set to 2 (including the initial interworking interfaces). The priority of each interworking interface is used to allocate the interworking interface with higher throughput to increase transmission speed under the condition of larger data volume, for example, the V01 priority with frame rate value of 60HZ is 3, the V04 priority with frame rate value of 120HZ is 1, the V05 priority with frame rate value of 80HZ is 2, and their starting sequence in the preset channel interworking model is V04, V05, V01 in sequence
