In this paper, the dual MPU dynamic signal automatic acquisition and analysis system is studied in depth, and the unique design ideas and the latest research results are mainly introduced. The system chooses the high performance MCU chip as the main controller, adopts the dual MPU parallel processing and the dual A / D chip combined modulo conversion technology, and completely resolves the bus competition brought by the multi-MPU common data memory through the hardware design problem. In the system, large scale integrated circuits are used to integrate charge amplifiers, adaptive range voltage amplifiers, programmable anti-aliasing filters, A / D converters, large-capacity nonvolatile data memories, graphic liquid crystal displays and communication interfaces. And the signal charge amplification / voltage amplification, filtering, sampling-maintaining and analog-digital conversion four parallel processing. The system has been successfully applied to the on-line recognition and monitoring of the turning process, with the expected results.
