As the depth and breadth Chanpianji rapid application development, and continually widened the Chanpianji areas, and in the application of the research is also growing in the important technical content or Danpianji as increasingly important research topic for many. ?? Chanpianji application areas are changing, and new types of Danpianji, dedicated Chanpianji the emergence and expand the outreach Danpianji technology, such as Danpianji wide choice, a new external devices and applications, smart sensors, such as virtual device exposition articles increased. ?? Chanpianji applications related technology has developed significantly to Chanpianji application system design methodology and content with a lot of changes. Chanpianji applications from the traditional forms Chanpianji plus external interfaces, films began to ASIC and system cluster (System On Chip) development of an increased significantly in real Danpianji production needs. This design task as a graduate design multifunctional few Hin table. The table can be measured and demonstrated several Hin pressure, frequency and impact of retail. And a RS232 interface and time show. The graduation designs chosen AK-4 Lwgy turbine flow sensors and pressure sensors, through MCS-51 Shanpianji to control operation of the signal data collection, processing and transmission. This could be pressure not only from the design works, the impact of frequency, time and other data in the retail and eight led digital control, but also through RS232 Chuankou, made to the data on the PC. On the PC by matching procedures will be shown in the information display data, the data show two parts Hin is identical. These figures show that for the second time unit, the unit is the impact frequency BM retail units to cubic meters / hour. At the same time, the system automatically timing, three minutes after the operation began automatically end measurement, display, and preserve information data.
