摘要
针对传统凝血分析仪通信系统的实时性差、可靠度低等问题,依据全自动凝血分析仪特点,设计一套基于CAN总线的通信系统。系统采用CAN总线实现分布式多节点间的参数传输;与PC端通过USB进行通信,通过既定的通信协议实现对整机的协同控制。经现场测试和验证,通信数据的正确率高、实时性好,大幅度提高了全自动凝血分析仪连续运行的性能。
Owing to the traditional blood coagulation analyzer has the features of bad real-time and low reliability,this paper proposes a new communication system based on CAN bus for full-automated blood coagulation analyzer. This system realizes distributed parameters transmission among multiple nodes with CAN bus,which communicates with PC using USB,and realizes the cooperative control of the entire system with the designed communication protocol. By field-testing,it proves that the new communication system has high correct rate and good realtime,and has greatly improved the performance of the system for continuous operation.
