Embodiment Construction

[0045] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0046] The present invention applies optical fiber sensing technology to structural damage detection and evaluation. In 1995, the German Berlin Structural Coverage and Modernization Research Institute bonded optical fibers to the components of the suburban railway steel bridge, and remotely tested them in the test hall of the Federal Materials Research Center. Monitoring, measured the crack development process of the transverse girder.

[0047] The technologies involved in the present invention include:

[0048](1) Structural health monitoring technology: Structural Health Monitoring refers to the process of damage diagnosis of infrastructure such as civil engineering and mechanical engineering. Specifically, the damage sensitivity features are extracted through the dynamic response of the mechanical system, and these features ar...

Abstract

The invention relates to health degree monitoring equipment for a framework type antenna cover structure. The health degree monitoring equipment works in a passive monitoring mode or an active monitoring mode, and is characterized by comprising a vibration generating unit, a sensing optical fiber and a monitoring degree monitoring device. The invention has another technical scheme to provide a health degree monitoring method of the framework type antenna cover structure. The equipment and the method provided by the invention can be used for monitoring and detecting the structure completeness health degree of the framework type antenna cover due to aging, fatigue, invisible damage, installation defects and the like. The health state of the antenna cover structure can be continuously monitored without interruption; instruction information can be timely given out when the repair is needed; and the situation that in the prior art, an antenna cover is used for protecting other equipment, but the self conditions of the antenna cover cannot be known is changed. The equipment and the method can be used for providing precise antenna cover structure health degree quantifying information forusers and repair persons; and the work mode of judging the antenna cover maintenance and repair quality by the subjective experience in the prior art is changed.

Description

technical field [0001] The invention relates to a structure health degree monitoring device and a monitoring method using the device, in particular to a structure health degree monitoring device for a frame type radome and a monitoring method using the device. Background technique [0002] The radome is mainly used for environmental protection of important equipment, and is usually installed in areas with poor natural environmental conditions. At present, most radome adopts frame structure and FRP composite material, and each unit plate is connected into a rigid structural whole through a special connection mechanism to resist the invasion of wind and rain on the equipment. [0003] Because the radome itself is directly eroded by harsh natural environmental factors, the structure and materials will age and loosen. If maintenance is not carried out in time, it will seriously affect its performance against wind and rain, and in severe cases, it will cause damage and collapse. ...
