Design of Dynamic Data Acquisition System of Virtual Reality Webpage

摘要

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.
