摘　　要：为了保证超声强化制备精细水煤浆先进工艺的良好效果,研究了精细水煤浆制备过程自动控制技术。开发了一种PXI总线结构的自动控制系统。系统采用虚拟仪器软件,能够经过自学习优化生产工艺参数,按照优化目标实时自动控制超声制备过程,并具有自动数据管理和发布等功能。In order to guarantee the advantage of ultrasonic treatment on ultra-clean micronized coal water slurry preparation,autocontrol technology of ultra-clean micronized coal water slurry preparation process has been researched. A autocontrol system which based on PXI bus structure has been developed. The software of the system adopt virtual instrument. The technics parameters are optimized by auto-training. Ultrasonic treatment process of ultra-clean micronized coal water slurry preparation has been autocontroled according to the optimized parameters. The data of coal water slurry preparation has been managed and shared by the system.
