| Abstract: | The design is based on the principle of double integral circuit by the integrator,zero comparators,operational amplifiers. With STC12C2052AD SCM as auxiliary components,the input analog converses with the use of SCM. It is proportional to the time interval. At this time in the counter on a constant frequency clock pulse count,count zero at the end of analog comparator. Simulation quantity will be converted to digital by the MCU artificial intelligence and control to detect. |
