摘要
Abstract
A multi-interface and high-precision pulse signal testing system with multiple communication interfaces and multi channels is designed to meet the demand for parallel measurement of multi-channel pulse signal parameters in the field of drone testing systems.The system uses a logic controller centered on a field-programmable gate array(FPGA),and 96 signals are input through six 16-bit data transmission chips of SN74LVC16T245.The system supports data interaction through three interfaces i.e.,Gigabit Ethernet,LVDS,and RS422,and is equipped with PC software to achieve human-machine interaction.Through actual engineering verification,the system can accurately measure 96 channels of pulse signals with a frequency range of 20 Hz～10 MHz and a duty cycle of 10％～90％,with both measurement errors less than 0.3％.The system can achieve data interaction through three communication interfaces,which meets the requirements of the task book design and provides important reference for the optimal design of drones.关键词
