Abstract
The use of computers for high-speed data acquisition has become an important part in modern industrial control,but there are still disadvantages only by single chip for industrial control.A method based on embedded data acquisition is introduced,which selects the ARM7 chip STM32F103VBT6 as the main chip,gives a system block diagram and designs the front conditioning circuit,A / D switching circuit and debug circuit,uses LINUX operating system and carries out the programming design.Practice shows that the embedded data acquisition system improved the system′s scalability and flexibility in the field of industrial measurement and control.The system has a wide application prospects.
