摘要
目的:目前医疗车辆方舱发展迅速,其内部需要监测的参数非常多。采用DCS存在布线复杂、系统可靠性低等缺点,引入CAN总线技术,可以大大减少布线,增强系统的可靠性。方法:利用OPC技术,通过VB开发温度监控程序和数据库应用程序,并应用模糊控制方法实现温度控制。结果:组建带有CAN总线的温度监控系统,探索CAN总线在医疗车辆方舱中的应用。结论:医疗车辆方舱中应用CAN总线技术,提高了系统的可靠性。
Objective Nowadays, with the development of medical vehicle, there are many parameters for inspection in its interior. It has disadvantages, such as complex routing and low system reliability, to use DCS. CAN bus technology can decrease routing and enhance system reliability. Methods OPC technology was used. A temperature supervisor control program and a database application were designed by VB, and the temperature was control by the fuzzy control methods. Results The temperature supervisor control system was established with CAN bus to explore the application of CAN bus in the medical vehicle. Conclusion It can enhance the system＇s reliability to use CAN bus technology in the medical vehicle.
