嵌入式系统在稀土萃取流量控制中的应用

Application of the Embedded System in Rare Earth Extraction Flow Control

对传统稀土串级萃取流量控制装置进行研究,提出了一种采用由变频器与嵌入式系统组成的装置对液体流量进行控制的方案。该方案利用脚本驱动开发工具V2.0,快速准确地开发了英威腾系列变频器的设备驱动,最终完成了嵌入式设备与变频器的通信。将该方案应用于生产现场后,实现了液体流量的精确、实时控制。

Having been researching the traditional flow control device in rare earth cascade extraction, the flow control strategy using the devices composed of inverter and embedded system is proposed. By adopting script driver developing tool V2.0, the driver for INVT series inverters is developed precisely and rapidly, and the communication between embedded equipment and inverter is completed finally. The strategy is applied in production site for implementing accurate flow control in real time.
