"基于多个MCU的实时数据采集系统设计与实践"

The "Single-chip Microcomputer Data Acquisition System Design Finalization.doc" summarizes a real-time data acquisition system based on multi-MCU communication. The system is composed of a monitoring computer unit, a data processing unit, a bus isolator unit, a receiving single-chip microcomputer, and a data acquisition unit. The data processing unit communicates with multiple field collectors through point-to-point serial communication. Within the data processing unit, the data from each channel is processed in parallel by dual CPUs, and the processing results are sent to the monitoring host in serial. Additionally, the data transmission between the acquisition unit and the processing unit, and between the processing unit and the computer, is carried out using RS-485 bus. The sampled data is displayed, filtered, and stored using the programmable keyboard/display interface 8279 chip. Practical application has proven that this scheme has excellent real-time performance. Key words include: data acquisition and processing system, single-chip microcomputer (MCU), serial communication, and parallel communication. The abstract summarizes the key components and functionality of the data acquisition system and highlights its real-time performance.
