| Abstract: | In the process of applying magnetic positioning technology， the complicated data processing and the large calculation amount often lead to that the real-time requirement cannot be met.In order to solve this problem， based on the parallel structure of FPGA， this study designs and implements a magnetic positioning scheme， including data acquisition，data processing and data output.The results show that the positioning accuracy can reach millimeter level when the height of the magnet with a magnetic moment of 0.1255A?m2] is within 20 cm from the magnetic sensor. Moreover， the positioning speed of the scheme is more than double that of using the general computer， which can satisfy most real-time requirements.It is more beneficial to the commercialized development of magnetic positioning technology and has broad application prospects. |
