Technical field
The present invention relates to the detection methods of structural health.The present invention is more particularly directed to the stress irradiance of intelligent wireless sensings to be
System.
Background technology
With the increasing that country puts into infrastructure, the rapid developments such as the various building structure such as bridge, pipeline in China.
No matter quantity or quality, China is at world forefront in infrastructure field.But these building structure build up with
Afterwards, by load, accident and external environment influence, material therefor is easy aging, structural damage is caused constantly to accumulate so that structure
Health degree declines with the increase of usage time, is easy to cause serious safety accident.For example, August in 2012 occurs on the 24th
Harbin Yang Mingtan bridge cave-in accidents；The Qingdao oil pipeline explosion accident that on November 22nd, 2013 occurs.These safety
Accident often leads to serious life and property loss.In this regard, other than reinforcing to the standardized administration of all kinds of building structure, to structure
The monitoring of health is also essential.
Supersonic testing method can be divided by being presently used for the technology of monitoring structural health conditions, piezoelectric detection method, X-ray detection and
Four kinds of classifications of Fibre Optical Sensor（Olawale, D. O.; Dickens, T.; Sullivan, W. G.; Okoli, O. I.;
Sobanjo, J.O.; Wang, B. Journal of Luminescence. 2011,131,1407–1418.）.But it is existing
With the presence of some shortcomings of monitoring technology, such as lack real-time detection function in situ, signal processing is responsible for, and cost is higher
Constructional difficulties, networking are not easy.Therefore, exploitation is a simple and practical, can monitor in real time in situ, and the structure with networking function is strong
Health prison examining system seems particularly significant.
Stress irradiance phenomenon refers to the luminescence phenomenon that material is generated by external stress stimulation, is such as bent, pressure, shake
It is dynamic, cutting etc..Based on the stress irradiance film or sensor made by this phenomenon, can be formed in real time in situ structure by
Your image of the load distribution arrived, has detection structure damage, deformation, damaged application potential.Currently, stress irradiance detects skill
Art has received extensive concern in international research person, such as：It is detected in high pressure hydrogen storage tank using stress irradiance film
Portion is damaged（Fujio, Y.; Xu, C. N.; Terasawa, Y.; Sakata, Y.; Yamabe, J.; Ueno, N.;
Murakami, Y.. International Journal of Hydrogen Energy, 2016.41(2), 1333-
1340.）；Stress irradiance technology is applied to the dynamic expansion of observation crackle（Kim, J. S., Kwon, Y. N., Shin,
N., Sohn, K. S. Applied physics letters, 2007,90(24), 241916）；Use stress light emitting material
To detect the crackle on bridge（8.Terasaki, N., Xu, C. N., Li, C., Zhang, L., Li, C., Ono,
D., ... & Shinokawa, T. (2012, April). In SPIE Smart Structures and Materials
+ Nondestructive Evaluation and Health Monitoring (pp. 83482D-83482D). San
Diego, California, USA. March 11, 2012. International Society for Optics and
Photonics.）.Compared with other detection techniques, stress light emitting material has monitoring in real time in situ, and signal processing is simple, can scheme
The advantages such as pictureization.In the stress light emitting material having found, SrAl2O4:Eu, Dy possess best stress irradiance performance,
Macroscopic green light can be sent out under the stress of 500N.
Invention content
The present invention is directed to develop a kind of wireless, intelligent, structural healthy monitoring system based on stress irradiance sensor.
The method of the present invention relates to the use of a kind of stress irradiance sensor and a kind of wireless communication technique of simplicity, is aided with electricity
Source and signal management module, are combined into a set of structural healthy monitoring system.The system using stress irradiance sensor can according to by
The feature that the light of varying strength is sent out to external force size, to be monitored in real time to the health status of various structures.
Described stress irradiance sensor refers to by SrAl2O4:Colorimetric sensor films made of Eu, Dy are used for detection structure body
Health status is simultaneously converted into optical signal output.
Described easy wireless communication technique refers to ZigBee technology, which has at low cost, and communication is reliable, networking
The advantages that convenient.
Described power supply and signal management module refers to the circuit module of designed, designed, and the module is using four No. 5 batteries of section
Power supply, and by power distribution to all parts.Acquire the optical signal of stress irradiance sensor and by circuit simultaneously
