Title The test system of force and acceleration based on MCU
Abstract
The war in the fight against the target, a large number of ammunition spread, has become increasingly not adapted to the war needs of the times.Smart smart ammunition came into being, In modern warfare,The effect of the reduction and rotation of the smart and intelligent ammunition and the function of the steady state scan platform is to provide a steady state scan environment for the sensor or seeker, so as to realize the function of detection, recognition and tracking.The research on the flight of the ammunition and the analysis of the steady state scan process can promote the development of smart munitions.
This subject takes 51 single-chip microcomputer as the core, collects the sensor data, stores it to the SD card, and uses the numerical analysis software to process the data.The data transfer mode of the sensor to the SD card and the dynamic display of the 1602 LCD is analyzed.Draw the experimental circuit diagram, build the hardware single path real operation.Experiments show that the liquid crystal can display dynamic parameters in real time, stable performance, power and rotational speed measurement is relatively accurate, no error can be used as the practical circuit of the microcontroller.
