閥門電動執(zhí)行機構近年來逐漸取代機械式執(zhí)行機構,成為工業(yè)控制系統(tǒng)中不可或缺的
一個執(zhí)行單元。本文對執(zhí)行機構的各個單元進行了設計和開發(fā)。開發(fā)了安全、可靠、方便、先進的閥門電動控制系統(tǒng)。閥門控制系統(tǒng)是電動執(zhí)行機構的核心單元。在單片機ATMega64L和微型PLC 上分別開發(fā)了友善的人機交互單元和可靠的電機控制單元,兩個單元之間通過串行通訊交換信息。

Abstract: Electric valve actuator has replaced the mechanical valve actuator and becomes
indispensable execution unit of the industrial control system. We design and develop each unit of the actuator respectively, develop the mechanical structure by mechanical & electrical integration and devises safe, reliable, convenient, advanced electric motor control system. Motor control system is kernel unit of electric valve actuator. The friendly human - machine interactive unit based on Microcontroller ATMega64L and reliable motor control unit based on mini – PLC was explored. These two units exchange message by serial communication.
