AUTOMATED CONTROL SYSTEM OF NATURAL VENTILATION DYNAMICS IN SEALED CONTAINER, AND ITS APPLICATION METHOD Russian patent published in 2012 - IPC G01M99/00 

FIELD: machine building.

SUBSTANCE: according to the invention, the control system includes control unit that consists of electric power supply, analogue-to-digital converter of information and power control signals in the form of interface conversion unit, sensors, switching means of information and power control signals in the form of interface input-output unit, which are electrically connected to digital electronic computing device and connected to electric drives of controlled working members of actuating devices constituting the system of actuators, electric drives of controlled working members of group of actuators, pneumatic lines connecting the sensors to actuators and to sealed container. Electric pneumatic valves, each of which is arranged in pneumatic lines connecting them to the sealed container, are used as actuators. In addition, electric pneumatic valve of one pneumatic line is connected to oxygen sensor, and the other one is connected to the filter interconnected with the environment. Electric pneumatic valves have direct and return electric connections with the control unit via control and power supply chains to control the change of position of working members of electric pneumatic valves.

EFFECT: providing the possibility of controlling the dynamics of natural ventilation in such containers; providing the controlled oxygen inflow from air in them.
