Embodiment 1

[0042] Embodiment 1, the method for realizing the flying line effect based on web front-end technology, such as Figure 1-5 described, including the following steps:

[0043] 1. Set the data filter condition a1 to filter the data that needs to be drawn on the large screen.

[0044] For example, set the data filter condition a1 as: threat level 10 (highest)

[0045] 2. Add the filter condition a1 to the data request interface, and automatically request the server for the data that occurred within the last t seconds of the current time every t seconds. 3s≥t≥1s, t is 3 seconds in this embodiment.

[0046] Assuming that the current time is T, request data from the server at T+n*t time.

[0047] That is, request the data that meets the condition a1 and the event occurrence time [T-t, T].

[0048] n≥0, n is the number of requests.

[0049] Get the request data for several t seconds. The request data includes elements such as the origin and purpose of the address, and the time ...

Abstract

The invention provides a method for realizing a fly wire effect based on a web front-end technology. The method comprises the steps of setting a data filtering condition a1; according to the filteringconditions a1, receiving the request data, establishing a data processing queue A, sending the obtained request data to the data processing queue A, drawing a flying wire from the advanced data of the request data in the data processing queue A, positioning a source address and a destination address on a map according to the addresses contained in the advanced data, drawing the flying wire between the source address and the destination address on the map, and counting 1; storing the drawn data, the fly wires and the counts as the fly wire data in a reserved fly wire library. According to themethod, by acquiring the data in the recent preset time in real time, drawing the data in a queue form, and displaying the data on the map, the source address and the destination address of the real-time data meeting the conditions is emphatically displayed, and the method has the advantages of high efficiency, good performance, good interaction effect, prevention of memory leakage and improvementof data processing efficiency.

Description

technical field [0001] The invention relates to a large data screen technology, in particular to a method for realizing the flying wire effect based on the web front-end technology. Background technique [0002] Under the premise of big data, large data screens have emerged as the times require, and how to display data more brilliantly through web-side technology is particularly important. How to display massive data? How does the displayed effect vividly reflect the scene? [0003] In most visualization projects, front-end technologies such as svg, canvas, and webgl are usually used to draw large-screen data. However, in complex graphics that are updated in real time, such as the flying line effect display on the map, it is difficult to solve any of the above drawing techniques. This situation requires special handling to restore massive amounts of data with higher performance and more dazzling interactions. The traditional way is not only difficult to display, but also...
