Abstract:
A ModBus protocol based high precision grating displacement measurement instrument was designed by using STC89C51 microcontroller in this paper． According to the principles of grating displacement transducer，a fractionized circuit for the grating signals was designed to achieve grating pulse interruption and motion direction identification for the singlechip with improved measurement precision，and then the measured results are presented with a LCD display． To enhance the compatibility with the AI series measurement meters，a 485 interface was also designed for data communication with computer based on the ModBus protocol． The experimental displacement measurement for kyropoulos sapphire growth using a LE Moire grating ruler proved that the precision was enhanced for 4 times with good ability of anti-interference and suggested the industrial application with long transmission distance，high data transfer rate and good reliability．
