"数据采集系统设计及应用研究"

The topic of this paper is the design of a data collection system. Data collection technology is a comprehensive technology based on analog signal processing, digitalization, digital signal processing, and advanced computer technology. It serves as a bridge between the analog and digital worlds. The core component of a data collection system is mainly implemented by a microcontroller. In any microcontroller measurement and control system, the process starts with obtaining the data in digital form as quickly, accurately, and thoroughly as possible. Therefore, the data collection system plays a vital role as an essential bridge between the analog and digital domains. This system utilizes VB programming to develop upper computer data processing and display programs. The upper computer can control the lower computer to perform continuous data collection and single data collection through commands. The lower computer's data collection can also be stopped using commands. This paper focuses on the application of the Atmega8515 microcontroller, which mainly aims to collect and transmit analog data from one terminal to another. Such a system finds wide use in industrial control and intelligent instruments. In summary, the data collection system described in this paper is crucial for connecting the analog and digital domains. It is implemented using a microcontroller and utilizes upper computer programming to process and display data. The paper mainly focuses on collecting and transmitting analog data using the Atmega8515 microcontroller. This system finds extensive application in industrial control and intelligent instruments.
