Research On The Application Of USB And Wireless Data Transmission In Motor Fault Monitoring

With the development of industrial and agriculture automation, motor is used more widely in this domain. So the fault of the motor will influence people's daily-life and industrial production. Research on the motor fault monitoring can help forecasting and repairing the motor fault.This paper introduces the research background and significance firstly, then expatiates methods about data transmission, motor fault analyse and the problems existing in these methods. The USB2.0 protocol which is needed to master in USB developing is also researched deep in this paper.This paper proposes a data transmission scheme based on wireless and USB interface technique. This paper also accomplishes the design of hardware and software about wireless data transmission unit based on nRF24L01; the development of system software based on MCU ATmega64; and firmware programming development and hardware design of USB interface data transmission chip CY7C68013. Aiming at the application in this certain system, using VC++6.0 to actualize the software design in PC. And the system realizes the high speed wireless data transmission based on USB.The experiment debugging is also done in this paper. The experiment results reach the expected goal. The system can transmit data quickly and exactly from motor to PC. So the data transmission scheme based on wireless and USB interface technique is feasible and correct. The technologies discussed in the paper can also be used in other data acquisition and monitoring system in the industry or digital entertainment device.
