The reporter learned from Harbin Engineering University on the 4th that the Huarong technology team composed of graduate students from the school has developed a domestically-made marine diesel engine electronic control system with completely independent intellectual property rights. boat application requirements. This young scientific research team installed a domestic “brain” for my country’s diesel ship power plant.
This system breaks through the key technology of diesel engine electronic control, and successfully develops an electronic control system with independent intellectual property rights and advanced performance. Guarantee and maintenance capabilities.
The power plant is responsible for providing the ship with the power and electricity required for navigation, electronic equipment, communication and navigation equipment, and the life of the crew. Its performance directly affects the vitality of the ship and the living conditions of the crew. At present, my country’s ship power is still dominated by diesel engines, accounting for more than 90% of ship power. Since the 1970s, my country has introduced a variety of advanced diesel engine production licenses, but the supporting electronic control system with “brain” function has been regarded as the core technology by developed countries. The software and hardware have long relied on foreign technology and components, which restricts domestic ships. industry development.
Under the guidance of Professor Li Wenhui from the Research Institute of Power Device Electronic Control Technology, School of Power and Energy Engineering, Harbin Engineering University, the team determined the matching selection of tens of thousands of components through in-depth research. In order to ensure the reliability of the system hardware platform design, combined with hardware design optimization technology, the team completed the design of the electronic control system hardware platform based on 100% domestic components through repeated testing, modification, and optimization. At the same time, based on artificial intelligence optimization and advanced control algorithms, they independently developed the electronic control system software. It took more than a year to realize a localized integrated electronic control system with functions such as real-time monitoring of diesel engine performance status, fault diagnosis and isolation, and automatic speed adjustment.
The electronic control system has completely independent intellectual property rights. It can not only realize real-time monitoring of more than ten operating conditions of marine diesel engines, including speed, fuel consumption, exhaust temperature, etc.; it can also independently adjust engine speed indicators according to working conditions to ensure marine diesel engines Stable and safe operation. When a fault occurs, the system will automatically identify and diagnose the fault point, improve the maintenance efficiency of the staff, and greatly shorten the maintenance time.
