Abstract

The invention provides a full-digital control system based on a safety type high-speed autonomous bus, a flattened system structure and the full-digital control system based on the safety type high-speed autonomous bus are adopted, so that the number of equipment and cables is greatly reduced, the staffing level is reduced, and the intelligent level and the reliability level of the system are improved; the integration and full-digital control of the control system of a submarine nuclear power device are achieved, and measurement, control, protection and operation management are efficiently and reliably conducted on the submarine nuclear power device. The dynamic automatic reconstruction of system functions and automatic starting and function recovery under the condition of failure of any control module are realized by adopting the acquisition control module based on rapid algorithm scheduling, and the reliability of the system is further improved. According to the invention, an auxiliary decision support function design based on big data mining and fault diagnosis is adopted, designs such as online fault diagnosis and auxiliary decision support are developed, and the intelligent level of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of control, and in particular relates to an all-digital control system based on a safe high-speed autonomous bus. Background technique [0002] The literature on foreign submarine nuclear power plants shows that the development of submarine nuclear power plant control systems has undergone three digital upgrades and improvements, from analog control, digital-analog hybrid control to digital control, and the level of automation and digitalization has been continuously improved. Foreign nuclear submarines generally adopt the "three horizontal and three vertical" architecture of the operation management layer, control and protection layer, and input and output layers, realizing the digital control of submarine nuclear power. However, the improvement of the level of digitalization has also greatly increased the number of cables used on submarines, and the reliability requirements for digital control equipment ha...
