Description

technical field [0001] The invention relates to the design of an embedded circuit system, which realizes the functional requirements of the whole system through each functional circuit. Background technique [0002] For modern ship transportation, ballast water is necessary to ensure the safe and efficient operation of the ship, and to ensure the balance and stability of the unladen ship. However, it also poses threats to the ecological environment, economy and human health. Every day, hundreds of millions of marine life are transported around the world in ships' ballast tanks. Invasive species not only pose a threat to the local ecological environment, but also cause harm to the lives of residents in coastal areas and even further inland areas. The IMO ranks the invasion of marine species through ships' ballast water as one of the four most threatening ocean problems. [0003] For the above-mentioned environmental pollution problems, relevant companies in various countri...
