ARM-based secure data acquisition and storage system for communication

The current conventional data acquisition system has low processing performance due to the lack of optimization of the hardware processing chip, for which an ARM-based secure data acquisition and storage system for communication is proposed. Based on ARM chip, the hardware parts such as data serial port and chip are designed, and USART data are acquired, file reading and writing modules are designed, and recursive average filtering algorithm is used to reduce data noise. The experimental results show that the proposed data acquisition system has a high accuracy rate and a more desirable data processing performance.
