Abstract

The invention discloses a virtual type mechanical fault diagnosing instrument and method for an Android platform. The diagnosing instrument comprises a sensor module, a signal conditioning module, a data collecting module, a Bluetooth or WIFI transmitting module, Android equipment and a mechanical fault diagnosing system arranged in the Android equipment. The diagnosing instrument is characterized in that the data collecting module can receive control instruction sent out by the Android equipment through the Bluetooth or WIFI transmitting module and can collect signals of objects to be tested according to the instructions, meanwhile the data collecting module can transmit A/D converted data to the Android equipment through the Bluetooth or WIFI transmitting module, and the mechanical fault diagnosing system arranged in the Android equipment comprises a wireless communication function module, a time domain analysis function module, a frequency domain analysis function module, a displaying module, a storage module and a collecting control module. The mechanical fault diagnosing instrument uses the Android equipment to analyze mechanical signals in an online and offline mode to obtain vibration characteristics of mechanical equipment and can be widely applied to mechanical fault diagnosis.

Description

Technical field: [0001] The invention relates to a pseudo mechanical fault diagnosis instrument and method, in particular to a virtual mechanical fault diagnosis instrument and method on an Android platform. technical background: [0002] Most of the traditional mechanical fault diagnosis instruments are based on the PC platform or hardware instruments, which have disadvantages such as inconvenient to carry, too many connections for on-site use, inconvenient instrument modification, and poor scalability. The current mechanical fault diagnosis instrument has put forward requirements that the traditional mechanical fault diagnosis instrument cannot meet in terms of the appearance size of the instrument, the convenience of carrying, and the convenience of use. This patent proposes a virtual instrument with strong flexibility, powerful functions, economical and practical, easy to carry, convenient to test, and highly integrated test functions. This patent can be widely used in i...
