Abstract:To achieve the automatic control of the production process, we must first achieve the parameters of the production process in real time, reliable detection. The parameters of the production process to achieve automatic detection is a prerequisite for automatic control. No parameters of the test will be the prerequisite and basis for the loss of automatic control. Detection technology development, in order to raise the level of
control. Some of the constraints of its production process automation to increase the level of the bottleneck, is often difficult to real-time parameters, reliably detected.
Weeks to test the vibration machine in the no-load conditions, the main axis of the no-load vibration frequency and amplitude, for the equipment in the work of the complex process of vibration parameters on-line test had not been able to solve very good. Peripheral vibration drilling machine spindle at work, at high speed spindle rotation velocity and high frequency oscillation, combined with its main components --- exciting drive their own quality of the smaller, so the sensor attached to the quality of weeks vibration The movement of spindle drilling machine, especially for some of the swing of the impact, if contact with sensors to measure, is sure to test the reliability and accuracy have a huge impact, which determines the need to contact all the way To measure the sensor can well meet the requirements of the system of measurement, this must be a non-contact way to measure. And the design of eddy current sensors (eddy current sensors in high-speed rotating machinery and mechanical movement of the reciprocating state analysis, vibration analysis measurement, high precision non-contact vibration and displacement signals can be accurately in a row Rotor collected a variety of parameters of the state) on the axis of the situation in the no-load test data will be carried out through the amplifier amplification, A / D will enlarge the data conversion, input AT89C51 single chip for data analysis, processing, by LED Will be LED-frequency vibration, the amplitude displayed.
