【Abstract】 The paper deals with a type of double-channel vibration sped measurement and controldevice, which uses magnetorelectricity vibration sensor and takes singlechip microcomputer as its core.Vibration speed is accurately measured when large-cale circumrotation machinery is working, to judgewhether working state of circumrotation machinery is normal or not and to control efficientlysyntony state of large model circumrotation machinery. The device is characteristic of simple structuregood perfortmance and reliable work.更多还原
