Title The research of data acquisition and transmission system based on ARM embedded system
Abstract
With the rapid development of technology,the demands on data acquisition are enhanced. Embedded system is one of the leading-edge technologies nowadays,It can be used to enhance real-time feature and flexibility of system,so as to meet the increasing measurement needs.The study of embedded data acquisition system based on ARM is such a case.
The system uses A/D converter chip UCB1400 collect data, transforming the analog signal into digital signal and processing through the ARM processor. Finally,the date will be transferred to the peripheral through the UART interface using protocol RS-232 and the purpose of the system design will be achieved. This paper gives the hardware schematics of the data acquisition and transmission system based on ARM embedded system and the program of data acquisition and communication transmission control software.
