| Abstract: | The design of the intelligent instrument for high speed vibration data acquisition and emergency fault record is introduced. The instrument is a intelligent data acquisition device which can sample 4 channels of vibration signals, 4 channels of procedure signals,8 channels of switch signals, one channel of rotating signal,and one channel of key phase signal. The instrument includes signal adaptor,MAX120A/D conversion and its outbroad control circuit, single chip microcomputer system and so on, which centres around MAX120A/D conversion. Data acquisition of vibration signal can be realized by using MAX120A/D conversion. 8098 single chip microcomputer is used to detect 4 channels of procedure signals and supervise acquired data. |
