Realization of the algorithms of digital filter on electromagnetism valve based on JN5121 single chip computer

Hydraulic pressure system is the guarantee of the mechanism equipment for working in gear; it is also the happening point of system trouble.In order to detect variations of the system signal much more exactly and speedy,and also improve the operation efficiency,This paper gives a new filter algorithms on acceleration and magnetism signal that has been detected by the hydraulic pressure electromagnetism valve system based on the JN5212 MCU,and also analyze the principle,working flow chart and the function.It also gives a comparison on our results and the filter effect of digital filter in MATLAB toolbox on the magnetism signal and educes the result that it is in advantage of dealing with sampling data much more speedy.
