Method and device for controlling automatic adaptive frequency of data visualization large-screen page

Abstract

The invention discloses a device for controlling the automatic adaptive frequency of a data visualization large-screen page, and relates to the technical field of information. The system is composed of an event monitor, a timer, a page self-adaptive signal trigger and a time window definition device. According to the device for controlling the automatic self-adaptive frequency of the data visualization large-screen page, the event monitor is used for monitoring an onsize event; defining a time window for triggering a page refreshing instruction by using a time window defining device; a timer is used for carrying out delayed timing according to the time of the time window; a page refreshing instruction is executed by using a page self-adaptive signal trigger, the purpose of effectively controlling the refreshing times of a large-screen page is achieved by triggering an onsize event timer for timing again each time, and the user experience effect is considered by setting a time window.

Description

Technical field

[0001] The present invention relates to the field of information technology, especially the field of software development. Background technique

[0002] There is an important branch of the data visualization page, that is, the page that is specifically displayed on some professional equipment, which is called the large-screen display page in the industry for short. The display environment of such large-screen pages is often a high-definition projector, or an LED screen, or a giant screen environment similar to a theater.

[0003] This large-screen page has its own unique characteristics in design and development, which are summarized as follows:

[0004] Relevant definition: The visible interval of the browser is the interval in which the browser displays content. The visible interval does not include the browser's address bar, toolbar, and scroll bar.

[0005] Feature 1: The browser displays a large-screen page. The content of the large-screen often fills the entire ...

Examples

Embodiment 1

[0048] See figure 1 The device that controls the automatic adaptive frequency of the data visualization large-screen page is composed of event listener 1, timer 2, page adaptive signal trigger 3, and time window definer 4;

[0049] The onresize event is added by event listener 1, onresize points to timer 2, and event listener 1 is added to the statement of the large-screen display page. When the large-screen display page is completed, the onresize event of event listener 1 is triggered when the page size is changed, and Point to timer 2;

[0050] The timer 2 is defined by the time window definer 4, and the timer 2 loads the time defined by the time window definer 4, and the timer 2 is added to the statement of the large-screen display page, and the onresize event is completed directly Point to timer 2 and start timing function;

[0051] The page adaptive signal trigger 3 sends out the page adaptive command, and loads the page adaptive signal trigger 3 into the large-screen display p...

Embodiment 2

[0054] The inventor has investigated the time frequency at which onresize is triggered, and found that the limit of the frequency of onresize calls does not exceed 0.01 millisecond.

[0055] Generally speaking, the human eye will perceive a significant page load delay for page refresh operations under 300 milliseconds. Combining these two reference data, the present invention adopts the following methods to solve the technical problems discussed. The methods are as follows:

[0056] The present invention specifies a time interval for automatically refreshing the page. The reasonable value of this time interval is between 200 milliseconds and 500 milliseconds. This time interval is the timing duration, which is defined by the time window definer 4 in the present invention.

[0057] Timer 2 is the function of calling page adaptive signal trigger 3 through a callback function according to the timing duration defined by the time window definer 4. figure 2 Shown is the implementation cod...
