The Development Of Embedded Platform Based On System On A Chip And Its Application In The Power Equipment Examination

Embedded technology is one of the most widely used areas of industrial technology ,and Embedded System-on-a-chip (SOC) technology is the technical hot spot in the embedded field.SOC is the integrated device which want to pursue the biggest containing for product system. Through VHDL and such the hardware description language precise description system, it may complete a SOC system by the simulation confirmation.The overall system has advantage of high integration,small size,low power consumption and high production efficiency. The System-on-a-programmable -chip(SOPC) is the result of the PLD and the ASIC technology combined,it both has inherited the SOC merit, and because is the programmable system, has the nimble design way, may tailor, may expand, may promote, moreover may download the confirmation function as necessary, in the chip the logic modifies, the electric circuit layout modifies only just redownload, design cycle shorter, the production efficiency is higher.With the extensive application of programmable devices,IP core design development as well as the software and hardware coordination design technology development,SOPC application will certainly be more extensive.The work of this article comes from the needs of high-power transmission equipment capacitor dielectric loss detection,therefore first introduced the electric capacity equipment dielectric loss examination survey principle, and thoroughly analyzed the factor which affected the on-line monitor,determined the relative method to measure the dielectric loss and creatively developed a system-level design.After plan designed, this article studied the Altera FPGA SOPC design technology, including the periphery circuit design based on concrete application, the SOPC system development, synthesis, logical design, as well as software design technology based on NiosII processor. Then,designed and implemented the digital dielectric loss on-line monitor system in this foundation.
