These aotu control system is very important for long-range control in the rescue capsule This system can supply the oxygen for the rescue capsule automatically.When the oxygen concentration is lower than the setting value,let the oxygen in;when it is close to the setting value,stop oxygen supply. The setting values of oxygen concentration can be setted from the colorful touch screen,including the sensor range measurement,the open value and the close value of the oxygen solenoid,the open value and the close value of the sound-light alarm.When the oxygen concentration is lower than the setting value,DDC controller will send an open signal to the oxygen solenoid,it takes action and the oxygen is in the capsule,the oxygen concentration of inside capsule is increasing.this system have the assistant pipeline which is operated by manual,that is in case the auto operation does not work.
