Large-scale structure sensing resource conflict and function reuse collaboration and fusion monitoring system

Abstract

A large-scale structure sensing resource conflict and function reuse collaboration and fusion monitoring system comprises a blackboard which is used for recording original data, an intermediate structure and an evaluation result, an agent which is used for storing domain knowledge and a supervision and management main body; the agent which is provided with a communication interface performs communication collaboration with other main bodies through the blackboard; the supervision and management main body obtains blackboard data change to control the agent to achieve respective tasks and accordingly coordinates the integral system to achieve resource and function reuse of a distributed type sensing network and achieve rapid and accurate position of static load and impulsive load. The large-scale structure sensing resource conflict and function reuse collaboration and fusion monitoring system is used for monitoring structural strain signals caused by the static load and the impulsive load in large scale engineering structures and redundancy characteristics of different sensors and redundancy information of the same sensor are extracted by the distributed type sensing network which is formed by a strain sensor, an FBG (fiber Bragg Grating) sensor and a piezoelectric sensor due to collaboration of a self-organization sensor network and a estimation method to accurately and rapidly 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.

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.
