Description

Technical Field

[0001] The invention belongs to the technical field of shipbuilding, and in particular relates to an ozone concentration monitoring control system and method for a ship vegetable warehouse. Background Art

[0002] Due to the limited conditions, ships carrying out ocean voyages cannot update their vegetable supply as frequently as on land, and fresh vegetables are an important source of food to ensure balanced nutrition and good health for the crew. The current technical configuration of ship vegetable warehouses has certain limitations, because in most cases, the vegetable warehouses are only equipped with ozone generators to maintain the fresh quality of vegetables, and there are no ozone concentration monitoring devices and special ozone removal devices. This means that although the ozone generated by the ozone generator can effectively sterilize and preserve, the concentration in the vegetable warehouse may not be effectively controlled due to the lack of real-time monitoring and control. When the ozone concentration exceeds a certain safety standard, the strong oxidation of ozone will accelerate the metabolism of vegetables and cause decay. In addition, when operators enter and exit the vegetable warehouse, they will be affected by irritating gases, causing discomfort symptoms such as eye pain, coughing, and chest tightness. Long-term exposure to high-concentration ozone environments may even lead to more serious health problems. Therefore, in order to ensure the health and safety of operators and to better maintain the quality and freshness of vegetables, ship vegetable warehouses urgently need a system that can monitor the ozone concentration in the vegetable warehouse in real time and automatically remove excess ozone when the ozone concentration exceeds the safe range, so as to ensure the health of operators and the quality of vegetables.
