| Abstract: | The paper provides design and implementation of 8 channels time interval parallel measuring system with high precision, and solves measuring problem of 8 channel laser echo flight time for 1×8 linear array LiDAR. The hardware consists of timing board and control board, it is easy to exchange and extend, there is an ARM STM32 processor on the control board that configures TDC-GPX, reads measuring data, and uploads data to PC computer. The software adopts event driven programming method, and combines circular FIFO data structure and interrupt technique. Ranging experiment and data analyzing indicates that the measuring system is stable and reliable, and the conformity error is less than 2 nanoseconds for measuring same distance by different channels. |
