摘要
现场总线技术在旋转机械振动检测系统中得到越来越广泛的应用,其中PROFIBUS以其自身的优点占有非常高的市场率。采用TMS320F2812和SPC3设计了智能DP从站,具有处理能力强、实时性和安全性等特点,能广泛应用到电力、制造业自动化等领域。详细分析了从站的状态机,并介绍了硬件电路和程序,最后分析采用计算机模拟主站时的各种报文。该从站在采用CP5611和计算机作为主站的通信测试中,也获得了成功。
Filed bus technology is more and more wildly used in rotating machinery vibration monitoring system, and PROFIBUS has a very high market share because of its own merits. The intelligent slave station of PROFIBUS-DP based on SPC3 and TMS320F2812 is powerful, real- time and safe. So it can be extensively applied to electric power, manufacturing automation and other fields. The state machine of PROFIBUS-DP is analyzed in detail. And the hardware and software are also introduced. Finally, a variety of messages are analyzed when a computer simulates the master station. The system is also successful when using the computer and CP5611 as the master station.
