Study of signal measurement and data transmission based on singlechip and CAN bus

This paper mainly describes the method of measuring the time length of signals using singlechip and transmitting data information using CAN bus technology.This method overcomes the disadvantages of helicopter blade running elevation measurement,for example,slow signal transmission,bad stability and the high error code rate.The traditional analog circuit is transformed into the more reliable digital circuit,guaranteeing the helicopter blade running elevation measurement to go with a swing.
