Design of Dynamic Data Acquisition System of Virtual Reality Webpage

To improve the rate of dynamic data automated acquisition of virtual reality webpage, we design a dynamic data automated acquisition system of virtual reality webpage. We connect the LPC2292 controller pin and webpage extender, extract the webpage data initially, construct the RS485 data bus structure, perform the data transmission, design the system data intelligent conditioner, convert the webpage text data into signal data in the bus, and design the Modbus protocol as the communication protocol of the above two kinds of data. And at last, the network delay algorithm is used to eliminate the data acquisition delay and realize automatic data acquisition. The experimental data shows that after the acquisition system is applied, the acquisition time is reduced by 14% per data volume and the data acquisition volume is increased by 19% data per unit time. It can be proved that the system can improve data acquisition speed.

I. Introduction

At this stage, with the rapid development of global Internet technology and the continuous improvement of related software and hardware, the access bandwidth of network users has been continuously improved by accessing fiber or modifying network copper edge, etc. As a result of this trend, making the use of high-quality multimedia webpage and originals in the global Internet industry possible. Virtual reality technology can provide users with time display and various interactive entertainment modes according to the three-dimensional multimedia space display features created by their own data, so that users can have the immersive feeling. In modern e-commerce, tourism, educational training, scientific experiments and various entertainment modes, it has good application [1]. The design and improvement of Internet virtual reality webpage depends on the capture and collection of dynamic data on webpage. Different from the traditional targeted webpage, the virtual reality webpage provides a dynamic analog webpage for the user, and the constant change of the data will cause a certain network delay, which has certain influence on the data extraction. This kind of influence reduces the instantaneous rate of dynamic data collection, causing webpage to lose frames and reducing the user experience. Therefore, on the basis of ensuring a certain success rate, improving the high-speed acquisition of dynamic data of virtual reality webpage is the core research issue in the field of modern virtual reality webpage design. We introduce the LPC2292 controller as the basic configuration of the dynamic data input function, design the front-end acquisition part of the acquisition system, construct the transmission structure by using RS485 bus to improve the data transmission rate, connect the repeater at the end of the bus to change the signal format, and then calculate the network delay to achieve high-efficiency acquisition of virtual reality web page dynamic data [2]
