Description
Technical field
The present invention relates to a kind of positioning for the shockwave sensor for being beneficial to detection historic building fire prevention defect.The invention belongs to
Wood Inner Defect Testing and historic building conservation technical field.
Background technology
Stress wave nondestructive testing method is historic building fire prevention Inner Defect Testing method common at present.Its principle is root
The sensor of varying number is selected according to the shapes and sizes of detection object, determines the height of sensor device behind same section,
Sensor is equally spaced on testee again, taps sensor one by one, data acquisition is carried out to wooden component inside defect.It is tested
Produce stress wave inside thing under vibration, the propagation time under inner section difference path through matrix computations and reconstruct, by data
It is converted into X-Y scheme directly perceived.Tester passes through intuitively detection image and velocity of wave decay comprehensive descision wood component inside defect face
Product, defect shape, defect type etc..Effectively deploying to ensure effective monitoring and control of illegal activities for sensor directly affects the validity and accuracy of data acquisition.
The localization method to shockwave sensor is mainly by after artificial detection sectional plane positioning, recycling tape measure at present
Averagely lay sensor.The conventional method need to measure in batches, not only increase the working strength of testing staff, cause simultaneously
Measurement error value is larger.Detection sectional plane positioning generally requires the manually support to detection sectional plane height or component surface line etc.,
It is larger and destroy the Echtheit of wooden member bodies to there is error.In addition after detection sectional plane positioning, sensor is in same section
Non-homogeneous laying also directly affect collection path of each sensor to wooden component inside defective data, cause finally to detect data
It is larger with actual conditions gap.
Lack effective orientation problem in face of shockwave sensor, the present invention proposes a kind of simplified shockwave sensor and determined
The device of position, it is easy to scene and operates on the spot, both direction integration positioning in length and breadth replaces traditional sensor positioning method, accurately
Sensor positioning height and spacing, improve the accuracy of sensor propagation path.

The purpose of the present invention：It is to provide a kind of quickly to the positioner of shockwave sensor.The device itself is very
It is convenient, suitable ancient building onsite application, while the accuracy of the vertical, horizontal positioning of shockwave sensor is improved, it is effective to solve
The problems such as personnel's support or component surface underlining, improve the precision of stress wave data acquisition.
The purpose of the present invention is realized by following technical measures：Invent a kind of shockwave sensor positioner.It is special
Sign is, when detecting the wooden component in the longitudinal direction such as cylinder, by rotating detection sectional plane sensor locator, using sash weight to conduct oneself with dignity and draw
Suitable longitudinal detection sectional plane height is taken, it is determined that pull sensor Distribution and localization measuring scale after detection sectional plane, and passes through bales catch
It is quick to determine component girth with VELCRO stationary distribution positioning measurement chi, according to shockwave sensor quantity, can quickly draw every
The position that individual sensor is laid., can be in ends such as detection beam, a tree, used in making timber for boats when detection object is the longer wooden component of the transverse direction such as beam, a tree, used in making timber for boats
Fixed magic joint strip, it is mutually be bonded with detection sectional plane positioning measurement ruler end part reverse side, section positioning measurement chi is pulled to detection sectional plane
Position, sensor Distribution and localization measuring scale is pulled after determining detection sectional plane, it is quick to determine sensor distributing position.Not only reduce and pass
The problems such as ruler of system is slippery, detection sectional plane is uneven, while the working strength of testing staff is reduced, effectively improve detection effect
