Problems solved by technology
[0004] However, the following problems exist in the reliability evaluation of the system function reorganization strategy: 1) The system function reorganization strategy is closely related to the system itself, and it is difficult to propose a common evaluation model; 2) The system function reorganization strategy is a probabilistic event, And reorganization at different times has different impacts on system reliability, it is difficult to evaluate it

Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with examples.
[0028] For an aircraft monitoring system, the system is divided into six identical monitoring devices according to the principle of functional independence, and it is assumed that these six monitoring devices undertake functions TB1, TB2, TB3, LG1, LG2, LG3 respectively. Once a monitoring device fails, let TB2 and TB3 be loaded on one monitoring device, and the function performed by the faulty device is loaded on the idle monitoring device after TB2 and TB3 are merged, that is, after one device fails, the remaining five Each device performs functions TB1, TB2+TB3, LG1, LG2, LG3.
[0029] For the convenience of explanation, the initial function codes of each monitoring equipment are abbreviated below. For example, the monitoring equipment that initially completes the function TB1 is abbreviated as TB1, and so on, and the remaining monitoring equipment is abbreviated as TB2, T...

The invention discloses a method for evaluating the reliability of a function reorganization strategy, belonging to the field of reliability and safety. In the method disclosed by the invention, it assumes that functions born by n equipment in a function reorganization system are independent; if one equipment in the function reorganization system is failed, functions of n-1 equipment are reorganized; the reliability of the function reorganization system after function reorganization is calculated by two conditions; and thus, the reliability of the function reorganization system is obtained. According to the method disclosed by the invention, specific reliability evaluation of the function reorganization system is replaced by the function reliability; the problem that the function reorganization strategy of the function reorganization system is closely related to the function reorganization system itself can be effectively solved; a generic evaluation model is abstracted; the method disclosed by the invention can perform comparison analysis of the reorganization strategy of the function reorganization system; resources are sufficiently utilized; and the function reorganization strategy having relatively high reliability can be provided.
Description
technical field [0001] The invention provides a reliability evaluation method of a function recombination strategy, which belongs to the field of reliability and safety (safety system engineering). Background technique [0002] Functional reorganization is an important step in the realization of dynamic redundancy technology, and its main function is to prevent failures from affecting the operation of the system. With the development of integration, networking and complexity of industrial engineering systems, the requirements for reliability and safety are getting higher and higher. The appearance of the recombination capability further guarantees the reliable transmission of the network. When the system breaks down, or the system suffers from security threats due to other safety performance considerations, the system with reorganization capability can perform functional reorganization in time, restore normal operation, and ensure the reliability and security of the network...
