By utilizing the single-chip computer, a digital-to-analogue conversion extended module on periphery of the single-chip computer and the frequency converter together, digital quantity can be converted into analog quantity which is connected with a frequency converter 0-5 V voltage frequency setting port through the digital-to-analogue conversion extended module to perform frequency converting control to the frequency converter, so that changeable sine wave period outputting setting of frequency curve can be realized, and different rotate speed of the vibrating machine can be further controlled.

Description

technical field [0001] The present invention relates to a high-vibration-intensity MCU advanced control device for vibrating machinery and a control method thereof, which relate to a high-vibration-intensity single-chip microcomputer (embedded Micro controller Unit) control device, in particular to a high-vibration-intensity MCU advanced control device for vibrating machinery , belonging to the technical field of vibration utilization engineering. Background technique [0002] In many cases, vibrating machinery needs the vibration generated by the system during the working process, which has the characteristics of high vibration intensity (referred to as high vibration intensity), and has the vibration performance of a wide power spectrum curve to complete some special operations, such as vibrating screen machine The sieve rate is too low, the sieve is stuck, hardened; the vibratory vibration mill powder is not refined, easy to agglomerate, and reverse crushed; the material ...

AI Technical Summary

Problems solved by technology

[0004] (1) The high vibration strength increases the mechanical stress of the machine body, and the weak parts of the local body structure of the vibrating machine are easily twisted and damaged, such as the main vibration spring cracking, the vibration exciter bearing Premature failure, vibrating body and vibrating motor heat up or even burn out, the frequency of maintenance of main parts will increase significantly and the mass of the body will increase the energy consumption and cost of the system;

[0005] (2) The vibration force on the foundation is significantly increased, and the system noise is greatly increased, which seriously affects the operating environment of the operator or even becomes unbearable;

[0006] (3) When the system reaches or enters the high-order resonance mode area, the components will be damaged instantly or the whole machine will be paralyzed or scrapped, and the consequences will be disastrous

There are many reports at home and abroad on the use of frequency conversion technology for vibration machinery. Zhao Weiguang used the AT89C52 single-chip microcomputer to construct a test system for testing the real-time load of the ball vibration mill. Wan Wen et al. designed the control system of the electromagnetic vibration feeder based on MCS-51. Realized automatic feeding closed-loop control, etc., but the intelligent frequency conversion robust control device related to the high vibration strength performance of vibrating machinery has not been reported
