Description: 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.
