Large-scale structural sensing resource conflict and function reuse cooperative fusion monitoring system

Abstract

Large-scale structural sensing resource conflict and functional reuse collaborative fusion monitoring system, including: blackboard, used to record raw data, intermediate structure and evaluation results; intelligent agent, used to save domain knowledge, with a communication interface and communicate with other agents through the blackboard Communication and collaboration: Supervise and manage the main body, learn the data changes of the blackboard in real time to control the intelligent main body to complete their respective tasks, thereby coordinating the entire system to cooperate to complete the resource and function multiplexing of the distributed sensor network, and realize the rapid response to static loads and impact loads Accurate positioning. Monitor the structural strain signals caused by static loads and impact loads in large-scale engineering structures, use a distributed sensor network composed of strain sensors, fiber grating sensors, and piezoelectric sensors, and extract and fuse different sensors through the collaboration of self-organizing sensor networks and evaluation methods Redundant features of the same sensor and redundant information of the same sensor, in order to accurately and quickly monitor damage.

Description

technical field [0001] The invention relates to the field of engineering structure health monitoring, in particular to a large-scale structure sensing resource conflict and function multiplexing cooperative fusion monitoring system. Background technique [0002] With the development of materials and design, the structural performance of aircraft has been continuously enhanced. The comprehensive requirements of light weight, high reliability, high maneuverability, high maintainability, high survivability, supersonic cruise, stealth, long range and short take-off and landing have become modern requirements. An important criterion that must be followed in the structural design of military aircraft, the future structure will develop towards the direction of multifunctional intelligent structure. The use of structures and materials mainly includes four aspects: life cost, safety / reliability, performance and maintenance. From metals to composite materials, the rapid development o...

Problems solved by technology

For actual engineering structures such as aerospace vehicles, bridges, and dams, due to the large size of the structure, the sensor network required for structural monitoring includes a large number of sensor devices of different types, and the information obtained by each sensor is local and incomplete. , due to the greatly increased complexity of the required decision-making objects, the complexity of the monitoring network, the amount of calculation of signal information processing, the amount of information that needs to be communicated and transmitted, the management and coordination requirements between various parts of the system, and monitoring The energy consumed by the network has increased sharply. At the same time, various structural damage identification methods have their own limitations for actual complex structures.
