Design Of Mechanical Displacement Measurement System Based On STM32

Displacement measurement system is intelligent instruments which combinesmechanical, optical, electronic technology. It is widely used in advanced manufacturingtechnology, scientific research and modern industrial inspection, quality control andmanufacturing technology. Traditional mechanical displacement measurement device haslow accuracy, large volume, complex operation shortcomings, so cannot meet the needs ofproduction now, but digital display micrometer can be used for testing the mechanicalposition, with high precision, small volume, convenient operation and so on.This paper introduces a kind of mechanical displacement measuring system. Thissystem can realize the measurement of displacement and display the value. It usesSTM32F103RBT6,a32bit microprocessor, by receiving the command which is send fromserial console, reading and displaying digital content on the digital display micrometer inreal time, storing the data into EEPROM, which is convenient for future comparison,finally judge whether the value previous is over the normal displacement through theLEDs.First,this paper introduces the background and the significance of displacementmeasurement system; second,introduces the overall scheme of the system, analyzes theadvantages and disadvantages of the system; third, introduces the design of hardware andsoftware of the system, introduces the hardware circuit and software structure; and last,make an analysis and summary to the paper.
