In order to accelerate the development of the equipment fault diagnosis and condition monitoring technology in the enterprise of our country, mostly of which have more types and less amount of equipments, based on the construction of the network condition monitoring equipment management information system using integrated ideas, single 8-bit SOC plant was used as core MCU accomplished the system control and calculate function, which speed and efficiency partly reach that of the 32-bit MCU, based on which the electromechanical equipment monitor unit was constructed, and program enciphering was finished through setup corresponding parameters, which meet the demand of the research and smooth the way for the manufacture of this unit. Through analysis on the filter and the field test demand, the filter set was established in order to change the types and the frequency of the filters in the field and achieve the better effect based on the new field reconfigurable analog device according to the microprocessor arrangement mode.The high efficiency and low ripple switching power supply module was designed instead of the intrinsic module, at the same time, according to the noise result measured, the cutting point of the high and the low frequency was defined as 10 Hz, based on which the frequency-varying sample data device was used in the signal preconditioning circuit to realize the precondition of the broad range signals.In the equipment management information system, the setup of the access control was more important, the access management idea was applied to the data collect unit, with the USB communicating with the PC to exchange the route and the weight information to ensure the safety and the validity of the data. As above-mentioned, the route file system based on the Nor Flash was found,which included the functions such as memory administration, File administration, index administration and power-off protection.The embedded open system RTOS-TDNCOS was transplanted into this SOC plant, which can meet the demand of the real time and the stability of the unit, and shorted the development cycle, the driver program was encapsulated in the system with the certain modern too. Through working in the Bit-Reverse mode and in the frequency beyond the Rated frequency, the FFT arithmetic was transplanted into the embedded system and its performance was tested, which proved that this mode is feasible entirely.
