关 键 词：Pouring and pick equipment hand-held embedded system fault diagnosis signal analysis.
摘 要：正There are a lot of problems in pouring and pick equipments （PPE） which are widely applied in oil field, such as many different kinds of faults, dispersal of equipments, strict requirement for continuous working etc. But traditional fault diagnosis technology （FDT） based on PC doesn’t have adequate flexibility, so it can not satisfy the requirements as mentioned before. To solve these problems, a new kind of hand-held state monitoring and fault diagnosis system （SM-FDS） based on embedded technology was put forward. After detailed analysis of working situation and operating features of PPE, the realization way which is mainly based on the index of vibration is confirmed;Using multi-channel data collecting technology, hand-held circuit check is realized in real-time data collecting process. Signal analysis component library and graphical user interfaces （GUI） component library which can reconstruct and occupy small space are established to make characteristic extraction of signal, on-line analysis and diagnosis by multi-kind signal analysis method. According to specific requirements of hand-held instruments, monitoring system which has upper-lower position computer with dual-CPU computer architecture and low power consumption designation is realized. Industry experiments indicated that this system monitors accurately, works stably, and has a bright application future.
