基于开发板的医用紫外线灯控制系统设计

Design of medical UV lamp control system based on development board

目的:设计一种基于开发板的医用紫外线灯控制系统,以实现对医用紫外线灯的远程控制和使用时长记录。方法:该系统硬件由WeMos D1 mini开发板、1路继电器模块、OLED显示屏、RCWL-0516微波雷达传感器和ACS712电流监测模块组成;系统控制程序采用集成开发环境Arduino IDE编写。结果:经测试,系统的定时消毒和手动消毒工作正常,且系统计时准确;ACS712电流监测模块能够监测灯管故障和电路故障;系统在有人进入被消毒空间时能够立即关闭紫外线灯;在灯管使用时间达到设定的总时长时能够提示医务人员进行更换。结论:医用紫外线灯控制系统具有操作简单、成本低廉的特点,可实现对医用紫外线灯的远程控制和使用时长记录。

Objective To design a medical ultraviolet lamp control system based on a development board to achieve remote control and usage time recording of medical UV lamps.Methods The system was composed of a WeMos D1 mini development board,a 1-way relay module,an OLED display,a RCWL-0516 microwave radar sensor and an ACS712 current monitoring module,which had its control program written by integrated development environment(Arduino IDE).Results Tests proved the system developed functioned well in timed disinfection,manual disinfection and system timing;the ACS712 current monitoring module could detect the lamp failure and current failure;the system could immediately turn off the ultraviolet lamp when persons entered the space to be disinfected;the medical staff could be prompted to replace the lamp when it's about to run out of expiration date.Conclusion The medical UV lamp control system developed gains advantages in easy operation and low cost,and realizes remote control and usage time recording of medical UV lamps.
