Application background
Data acquisition systems are widely used in industrial measurement and control, environmental monitoring, etc. With the development of science and technology, data acquisition technology is developing in the direction of high precision, high speed, stability and reliability, integration and real-time systems.
Traditional products based on data acquisition and A/D conversion are unsatisfactory in terms of system volume, system power consumption, system data acquisition accuracy, and system processing capabilities. There is an urgent need for a system that can reduce power consumption and The volume is an embedded solution product that realizes high-precision data collection and high-performance system processing capabilities.
An Introduction
Hengyi embedded high-speed buffer AD acquisition system uses ATMEL’s 32-bit ARM as the system’s CPU, and a single chip integrates multiple functions. The system periphery expands the CPLD logic chip as a coprocessor, and expands the A/D data acquisition and conversion circuit module and the high-speed data acquisition buffer system FIFO, which can realize high-precision and high-speed data acquisition; rich peripheral interface resources; running embedded The Linux operating system is highly flexible, occupies less resources, and has high efficiency. It is oriented to petroleum exploration, environmental monitoring, industrial control, medical equipment and other fields. It collects and processes data and transmits it over the network. It has good real-time and logical performance.
