一种基于总线的智能型执行器系统设计

Design of a Intelligent Actuator based on the Field Bus Technology

在自动控制系统中,执行器同控制器或控制系统相连,共同实现对工业过程的控制。现场总线是过程控制技术、仪表工业技术和计算机网络技术三大技术领域相结合的产物。WorldFIP现场总线既是实时的,可预测的,又是面向未来的、能够和Internet连接的现场总线。本文对开发基于WorldFIP现场总线技术的智能电动执行器的软硬件进行了探讨,包括:MCU控制板卡,通信板卡和驱动板卡,以及相关软件程序的设计与开发。

In automation control system, the actuator the controller and the control system, cooperate to realize the control of the in- dustry process variables such as the temperature, the pressure, the flow, the displacement and so on. The field bus is combination of process control technology, instrument technology and computer technology. The WorldFIP field bus technology is a real- time, pre- dictable and future- facing field bus and has been used widely in the world. In this thesis, the hardware and software of...
