Abstract: Fault diagnosis method based on embedded acquisition equipment and SVM is proposed in the paper.The function of the module mainly includes data acquisition, data processing and data storage.SVM is trained by the features and the five states of rolling bearing. The structure of diagnostic model by SVM is defined as 5 input nodes and 5 output nodes,among which 5 input nodes are the features including peak factor,waveform factor,impulse factor,margin factor and kurtosis factor and 5 output nodes are the five states of rolling bearing include normal state, housing washer failure, retainer failure, rolling element failure and inner ring failure.The experimental results show that the diagnostic performance of SVM is effective.

Abstract: The current oilfield monitor model in domestic is out of date which causes serious oil and facility stolen. Public security is not complete and efficient to prevent the crime. In order to solve this problem, Photoelectric Beam Detector has been adopt. This study utilizes Photoelectric Beam Detector, first transforming its information to electric signal and then with the help of Data Acquisition Module and GPRS technology, sending the message to monitoring and supervision center where possesses the security system software. The results indicate that it is an efficacious method to fulfill the security and pre-warning target.
