摘要
多功能医疗分析仪在使用过程中,稀释器管路中会遭到样品堵塞影响其正常工作。为了保障仪器运行平稳安全,本文设计了适用于多功能医疗分析仪的防堵系统。系统采用低功耗的STM32F205VET6作为微处理器,使用模块化结构设计,包括压力检测模块、泵阀驱动模块、存储器模块、串口通信模块以及CAN通信模块等。运行过程中首先需要定标从而设定报警参数,之后分析仪正常工作过程中,可实时检测管路中负压,堵塞时自动报警并清洗,提高测量结果准确性。
Multi-functional health analyzer in use process,diluter samples were blocked in pipeline will affect their normal work.In order to ensure the equipment running smoothly,this paper design the suitable for multi-functional health analyzer to collect system.The system uses low-power STM32F205VET6 as microprocessor,with modular structure design,including the pressure detection module,pump valve drive module,memory module,serial communication module and CAN communication module,etc.Firstly need to calibration in the operation process to set the alarm parameters,and the normal work of the analyzer process,real-time detection of pipeline in negative pressure,jams automatic alarm and cleaning,and improve the measurement accuracy.
