Research on Monitoring System for Hospital Central Oxygen Supply Based on CAN Communication

目的研制一套基于CAN总线的远程实时监控中心供氧系统。方法在各临床科室供氧输入端安装氧气监控装置,采集供氧压力、流量和用氧量等参数,并通过CAN总线将其远程传送至中心供氧上位机。结果氧气监控装置能正常地采集压力、流量和用氧量等参数并将其传送至上位机,能正常地响应并执行上位机的控制命令;上位机能正常地显示监控状态。结论该监控系统可实现中心供氧的远程监控,提高供氧管理效率。

Objective To develop a set of remote and real-time monitoring system for central oxygensupply based on CAN total line. Methods Oxygen monitoring devices were installed in each clinicaldepartment to collect various parameters including oxygen pressure, oxygen flow and oxygenconsumption. Then the above parameters were transmitted to the upper computer of central oxygensupply through CAN total line. Results Oxygen monitoring devices can collect oxygen supplyparameters and transmit the parameters to the upper computer as well as can respond and execute thecontrol commands from the upper computer normally. The upper computer can display monitoring statusnormally. Conclusion The monitoring system which can implement the remote monitoring of centraloxygen supply will improve the management efficiency of oxygen supply.
