基于CAN总线智能输液系统的设计

Development of Intelligent Infusion System Based on CAN Fields

针对目前医疗输液过程中存在的问题,开发了一个基于CAN总线分布式测控网络智能输液系统,实现输液速度的自动检测和调节,并监视剩余药液的解决方案.实验室测试结果表明,系统输液速度的检测精度高,输液速度调节响应快、稳态误差小,储液瓶的液位监视报警输出信号准确、可靠.

This paper aimsat the problem of the infusion process. An intelligent infusion system based on CAN Fields supervisory network is designed to inspect and modulate the infusion speed automatically and supervise the remainder medicine in the bottle. The experiment resucts show that the measurement of the infusion speed is very accurate, the response of the infusion speed adjustment is rapid, the static error is small, the liquid level alarming output signal is reliable and accurate.
