Ballast water simulation circuit board based on STC12C5A60S single-chip microcomputers

Abstract

The invention discloses a ballast water simulation circuit board based on STC12C5A60S single-chip microcomputers. The ballast water simulation circuit board comprises a master control circuit of the STC12C5A60S single-chip microcomputers, an RS232 serial communication debugging circuit, RS485 remote communication circuits, an AD sampling circuit, an LED liquid crystal display circuit, a valve simulation and collection circuit based on a relay, an LED indicating circuit based on a latch chip 74HC573 and an analog quantity generating circuit of industrial standard signals. The master control circuit of the single-chip microcomputers is connected with the RS232 serial communication debugging circuit, and circuit debugging and communication are carried through an RS232 communication port. The master control circuit of the single-chip microcomputers is connected with the RS485 remote communication circuits to achieve remote communication. All controlled devices of a ballast water system can be simulated, factory debugging of the ballast system is facilitated, production efficiency is improved, ballast water debugging time is greatly reduced, and economical benefits are improved.

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...
