Question:

Get the method of the relay time parameter

Get the method of the relay time parameter

Answer:

In the process of contact will produce bounce, and finally to achieve a stable state, during which the microcontroller data collected or 0 or 1. Set the sampling period of the microcontroller 0.01ms, the data collected by the microcontroller address value multiplied by the sampling period, that is, the required action time. [2]
The detection principle is: when the relay coil when the contacts through the action time to be able to close, so the first chip to collect data 0, contacts closed after the acquisition of 1
The single-chip computer is connected with the coil drive circuit to control the energizing and discharging of the excitation coil, collecting the state of the contact when the relay is closed and broken, and calculating its time parameter
This method can detect the time parameters such as relay action time, action hopping time, release time, release back time
