Car tank monitoring device

Automobile oil tank monitoring device is based on embedded computer technology and communication technology as the foundation, uses the method of modern control theory to the automobile fuel tank quantity change of the velocity measurements and the amount of oil detection. oil tank monitoring system , Piecewise linear function to obtain the change of voltage and the amount of oil through the change curve change simulation oil quantity and fuel sensor voltage, the system according to user needs to set the sampling time, voltage sampling timing oil sensor value,through the function calculates the corresponding oil quantity value. While retaining the previous sampling value, automated fuel management system to judge the speed of change the amount of oil consumption, realize the automatic detection of oil quantity in oil tank, non normal working state generate alarm.
