摘　　要：现代的生物组织切片机存在自动化程度不够高、切片精度不能满足用户要求等缺点。为有效解决这些问题,提出一种基于STM32+FreeRTOS架构的全自动生物组织切片机控制器设计方法,该控制器控制切片机的执行机构及人机交互界面,实现了切片/修片模式可调、自动/手动切片可调、切片速度可调、切片厚度可调、切片厚度信息存储及切片计数等功能。经试验,切片厚度最小可达0.5 um,自动化程度高,性能稳定。Modern bio-tissue microtome has some disadvantages,such as insufficient automation,inadequate accuracy.In order to effectively solve the above disadvantages,a design method of controller for fully automatic bio-tissue slicing machine based on STM32+FreeRTOS architecture is proposed.The controller controls the actuator and human-computer interaction interface of the slicing machine,realizes the adjustment on slicing/trimming mode,automatic/manual slicing mode,slicing speed,slicing thickness,slice thickness information storage,counting functions and so on.The slicer using this control system has the characteristics of high automation,stable performance,and minimum slice thickness is up to 0.5 um.
