Method for measuring speed of conductor slipping through capacitive sensor |
摘要 |
A method for measuring a speed of a conductor slipping through a capacitive sensor. The method includes: sampling a capacitance of a sensing electrode at each preset time; determining a first threshold value and a second threshold value according to a peak value of the capacitance when the capacitance achieves the peak value; and determining the speed of the conductor slipping through the capacitive sensor by the first period and the second period, wherein the first period is defined as a period of time ranging from the time when the capacitance reaches the first threshold value to the time when the capacitance reaches the peak value and the second period is defined as a period of time ranging from the time when the capacitance reaches the peak value to the time when the capacitance reaches the second threshold value.
