Based on ARM9 RSIC CPU AT91SAM9260 and WinCE, the wireless data acquisition instrument for amusement ride was designed and developed. According to Ping-Pang mechanism, two buffers are created to save real-time sampling data in turns and the full buffer is saved to SD card between sampling timeslot. When data acquisition instrument begins to sample, the sampling start time is saved to a start time index file, and at the same time a directory coded by sampling start time is created to hold sampling data files. To avoid high bit error rate (BER), the length of data transporting frame is not over ...
