Multiple data acquisition system based on the AT89S52

摘要

The paper designs a multiple-data acquisition system based on the AT89S52. The system consists of two-way series A/D converter ADC0832, SCM AT89S52, extended 62256 RAM and LED display. It also describes the functional block diagram of system design, hardware interface schematics for each block and the software flow chart. By the acquisition, processing and display to the two road voltage signals, the results show that the system can realize the real-time data acquisition, processing and display for the multiple data, which has better versatility and can be widely used in the field of industrial automatic control.
