本设计是微机控制的制氧机压力测控系统。单片机系统通过压力传感器和检测比较器测得气缸内压力达到某一上限值(176 kPa)和下限值(64 kPa)时，单片机系统控制执行相应的动作(达到上限值时打开放气阀放气，达到下限值关闭放气阀进行充气)。如此反复循环,不断将氧气提供给需氧者。在此过程中若充气或放气10 s仍达不到设定值(176 kPa和64 kPa)则进行光报警。-The design is computer-controlled oxygen pressure measurement and control system. SCM system by pressure sensors and detection comparator measured cylinder pressure reaches a certain upper limit (176 kPa) and lower limit (64 kPa), the chip system control to perform the corresponding action (up to open the valve on the limit to fight deflation to reach the lower limit for closed discharge valve inflated). This cycle repeated continuously to provide oxygen to aerobic those. In this process, if the inflated or deflated 10 s still not reach the set value (176 kPa and 64 kPa) is the light alarm.
