Abstract
A FPGA-based life detection signal processing system design is presented. The life detector algorithm and its hardware and software systems are studied theoretically. In FPGA software design, the modular thinking was used to design FIR filter, asynchronous FIFO, UART, battery monitoring and functional control modules. The human body characteristic signal and the body movement signal are analyzed and extracted to achieve a non-contact detection and discovery of life circumstances. Compared with the traditional life detector, the device has small size, low power consumption, simple operation, easy to carry, etc., especially suitable for field and battlefield life detection and other applications.关键词
