Multi-channel high-speed data acquisition system based on ZYNQ

Abstract

The elevator balance coefficient is an important index to measure the safety operation of the traction elevator. The traditional measurement scheme of the elevator balance coefficient is time-consuming and laborious, and the improved measurement scheme is limited by the weakness of the traditional acquisition system, which leads to the popularization difficulty. In this paper, A multi-channel high-speed data acquisition system is designed by ZYNQ system core board, A/D acquisition module, SD card, and HD display screen. The system temporarily stores the collected data through FIFO, reads the data through DMA to PS terminal of ZYNQ, and stores and sends the data after processing by PS terminal. Finally, the QT platform is used to build a simple user interface to control the display of collected data. The experiment proves that the system realizes the high-speed acquisition, transmission, and display of multi-channel data, and has the characteristics of high acquisition accuracy and fast acquisition speed.
