Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a flowchart of a data display method based on an internet of things screen is shown.
As shown in fig. 1, the data display method based on the internet of things screen specifically includes the following steps:
step S101, at least one content data stream to be displayed is obtained, wherein a content data stream includes at least one content data arranged based on a time sequence.
In the step, the operation data collected by each equipment end are different, for example, a vehicle speed monitor can collect data information such as current longitude and latitude coordinates, vehicle speed and the like, and a temperature and humidity sensor can collect temperature and humidity information. Thus, each device outputs a different type of data and a different data structure. Thus, data streams acquired by a plurality of equipment ends in a time interval can be acquired simultaneously.
It should be noted that, a content data stream further includes first data for representing a device type and second data for representing a data type, where a first association relationship of one device type corresponding to a plurality of data types and/or a second association relationship of one device type corresponding to one data type exist between the device type and the data type.
For example, the temperature and humidity sensor has single functionality, so that the collected data is single, and most of the data only contains temperature and humidity data. Therefore, the second association relationship between the equipment type and the data type can be established, so that the data type can be determined more quickly after the equipment IP is acquired. For example, the vehicle speed monitor has rich functionality, and can acquire data information such as current longitude and latitude coordinates, vehicle speed and the like, so that a first association relationship of one equipment type corresponding to a plurality of data types needs to be established. For example, a vehicle speed monitor ID is associated with the longitude and latitude coordinate data information and the vehicle speed data information collected by the vehicle speed monitor ID, respectively.
Step S102, dividing the at least one content data stream according to a preset type classifier to obtain at least one content data stream set.
In the step, first data of each content data stream is acquired, and the association relation between the first data of each content data stream and the second data type of each corresponding content data stream is determined; if the association relation between the first data of each content data stream and the second data type of each corresponding content data stream is the first association relation, dividing each content data stream for the first time according to the first data to obtain at least one content data stream subset, wherein one content data stream subset comprises content data streams with different data types from the device type; and identifying the second data based on a preset type classifier, and dividing each content data stream in the content data stream subset for the second time according to the identification result to obtain at least one content data stream set, wherein the type classifier is a decision tree model.
It should be noted that the decision tree model can determine the probability that the data stream belongs to a certain type. And respectively inputting the data streams into a type classifier to obtain the probability that the data belongs to the type classification as each classification consistency rate of the data streams. And carrying out quantization marking on the data according to each classification consistency rate of each data stream to obtain quantization marks of the data streams, and classifying all the data into a plurality of content data stream sets according to the quantization marks of each data stream.
In a specific embodiment, after determining the association between the first data of each content data stream and the second data type of the corresponding each content data stream, when the association between the first data of each content data stream and the second data type of the corresponding each content data stream is the second association, dividing each content data stream directly according to the first data to obtain at least one content data stream set.
For example, the type of equipment of the humidity sensor is a humidity sensing device, the collected data type is also a humidity data type, and the humidity sensing device and the humidity data type are associated one to one, so that after the equipment type is obtained later, the collected data can be classified into the humidity data type.
Step S103, generating at least one data pre-display diagram corresponding to the content data stream set based on the preset conversion rule, where a data pre-display diagram includes at least one content data stream in the corresponding content data stream set.
In the step, the generation time of each content data stream in a certain content data stream set is acquired, wherein the certain content data stream set is any content data stream set in at least one content data stream set; sorting the content data streams according to the generation time, and making a difference between the generation time of the first content data stream after sorting and the generation time of the rest content data streams, wherein the rest content data streams are content data streams except the first content data stream in a certain content data stream set; and selecting at least one content data stream with the absolute value of the difference value smaller than a preset threshold value in a frame mode to obtain a data frame, and converting the image format of at least one content data stream in the data frame to obtain a data pre-display diagram corresponding to a certain content data stream set, wherein the data frame and the data pre-display diagram have a unique corresponding relation. Through converting the content data stream into the image, the display of the internet of things screen can be facilitated, and the phenomenon of data dislocation or messy codes is not easy to occur.
It should be noted that, for example, the data format of the content data stream is JSON data format, and thus the content data stream is converted into JPEG pictures. For another example, the content data stream is in doc data format, and at least one content data stream in the data frame is converted into jpg format.
Step S104, judging whether the actual size of the at least one data pre-display diagram is larger than the target size of the preset data display area.
In this step, if the actual size of a certain data display diagram is not greater than the target size of the preset data display area, the certain data display diagram is directly fused with other data display diagrams to obtain at least one target data display diagram.
Step S105, if the actual size of a certain data display diagram is greater than the target size of the preset data display area, updating the certain data display diagram until the actual size of the certain data display diagram is greater than the target size of the preset data display area, wherein the certain data display diagram is any one of the at least one data display diagram.
In this step, if the actual size of a certain data display diagram is greater than the target size of the preset data display area, the last content data stream in the data frame ordered according to the generation time is replaced or deleted until the actual size of the certain data display diagram is greater than the target size of the preset data display area.
For example, the content data streams in the data frame ordered according to the generation time are a content data stream a, a content data stream B, a content data stream C, a content data stream D, and a content data stream E, respectively. Since the actual size of the data display diagram generated by the current data frame is larger than the target size of the preset data display area, the content data stream E is replaced with the content data stream F with the data stream length smaller than the content data stream E. By means of the updating mode, the number of data streams displayed at one time can be increased as much as possible.
And the content data stream E is replaced by a content data stream F with the data stream length smaller than that of the content data stream E, at this time, if the actual size of the data display diagram generated by the updated data frame is still larger than the target size of the preset data display area, the content data stream F, the content data stream D, the content data stream C and the content data stream B are directly and sequentially removed until the actual size of the generated data display diagram is still larger than the target size of the preset data display area.
Step S106, fusing the updated certain data display diagram with other data display diagrams to obtain at least one target data display diagram, and displaying the at least one target data display diagram in a target data display area, wherein the target data display area is a partial area in the Internet of things screen, and the target data display area is larger than a preset data display area.
In the step, a first data frame corresponding to a certain data pre-display diagram and a second data frame corresponding to another data pre-display diagram are aligned according to the generation time, wherein the other data pre-display diagram is any one of the other data pre-display diagrams; and alternately sequencing the content data streams in the first data frame and the content data streams in the second data frame to obtain a third data frame, and converting at least one content data stream in the third data frame into an image format to obtain a target data display diagram. And displaying the target data pre-display diagram in a target data display area, wherein the target data display area is at least twice as large as the preset data display area. After the plurality of target data pre-display diagrams are obtained, the plurality of target data pre-display diagrams may be subjected to round display based on the time interval.
It should be noted that, the internet of things screen in this embodiment adopts a hong internet of things screen, and the hong internet of things screen mainly comprises: the Hongmon controller and the display screen integrate three-in-one functions of playing, sending, controlling and the like, and the functions of relevant components and implementation are as follows: the HongMong controller is an internet of things controller based on a domestic chip RK3568 carrying a hong Mong system, and is in butt joint with an internet of things platform through an Ethernet to realize platform information release and control data processing, and an RJ45 network port is connected with a display screen to realize display picture output, so that related control commands directly control external equipment. And (3) a display screen: and means for displaying the data.
In summary, according to the method, at least one data pre-display diagram corresponding to the content data stream set is generated by at least one content data stream set based on a preset conversion rule, and the data pre-display diagrams are fused, so that the data streams can be displayed in the internet of things screen more quickly, the phenomenon of disordered data display is not easy to occur, and when the actual size of a certain data pre-display diagram is larger than the target size of a preset data display area, the certain data pre-display diagram is updated until the actual size of the certain data pre-display diagram is larger than the target size of the preset data display area, and in this way, the fact that more data streams can be displayed at one time when the data pre-display diagram is suitable for the internet of things screen display is achieved by updating the data pre-display diagram.
