CONTROL METHOD USING PRESSURE SENSOR FOR AIR SUPPLY TO AIR-CAVITY OF AIR-CAVITY VESSEL

摘要

PURPOSE: A control method for supplying air to an air chamber using a pressure sensor of an air chamber ship is provided to prevent the waste of energy according to excessive operation of a compressor by maintaining a buffering state with air in an air chamber. CONSTITUTION: A control method for supplying air to an air chamber using a pressure sensor of an air chamber ship is as follows. Pressure sensors are respectively installed at the bottom of a hull and at the top of an air chamber to measure pressure(S10). The difference of measured values between the pressure sensor at the bottom of the hull and the pressure sensor at the top of the air chamber is calculated to measure the water level in the air chamber(S20). The measured water level is transmitted to a controller(S30). The controller detects proper water level to determine whether the water level is changed over a reference water level(S40). If the water level is changed over the reference water level, the controller controls to operate a compressor so that the air chamber can be filled with the air(S50). Whether the water level is changed or not is determined by receiving the measured water level through the pressure sensors(S60). The controller stops the operation of the controller if the water level is maintained for a constant time(S70).
