Problems solved by technology
[0005] Second, for the four-redundancy voting mechanism, it is impossible to adopt the majority unanimous voting method like the three-redundant degree. It is necessary to consider the calculation results of the two computers to be consistent, and a comprehensive voting mechanism is required.
However, due to the need for external intervention, this method cannot achieve the purpose of independent voting, and is prone to misjudgment.

The invention relates to a redundancy ship heading control method and a ship heading control system. The method comprises the steps that desired ship heading parameters and current ship heading parameters are received; at least two rudder order operation modules with ID numbers are used to calculate yaw data according to the desired ship heading parameters and the current ship heading parameters respectively, and the rudder amount of a steering gear is calculated as a rudder order according to the yaw data; a main rudder order operation module is specified from at least two rudder order operation modules with ID numbers according to preset ID number priority, and the remaining rudder order operation module is a standby rudder order operation module; and the rudder order calculated by the main rudder order operation module is selected as a control rudder order and sent to the steering gear. According to the invention, a number of rudder order operation modules calculate the rudder amount of the steering gear according to the yaw data respectively to acquire the rudder order; a rudder order operation module is selected as the main rudder order operation module; and the rudder order of the main rudder order operation module is used as the control rudder order and sent to the steering gear, which is simple and practical.
Description
technical field [0001] The invention relates to the technical field of redundant ship control systems, in particular to a redundant ship heading control method and a control system. Background technique [0002] Application of redundancy technology is an effective means to improve system task reliability, safety reliability and fault tolerance. For systems with high reliability requirements, only the method of improving the reliability of the component parts of the system is used. The effect of improving the reliability of the system is not significant, but the price paid is very high. Using redundancy technology, components with relatively low reliability can be used to form a high-reliability or ultra-high-reliability system, that is, the high reliability of the system can be obtained by paying an extraordinary resource cost. From a theoretical analysis, the higher the redundancy, the better the safety performance, but the calculation is more complicated and error-prone, ...
