Description
Technical field:
The present invention relates to a kind of supersonic reflectoscope.
Background technology:
Existing supersonic reflectoscope, owing to reasons such as structure and principle of work, cost height, efficient are low.
Summary of the invention:
The object of the present invention is to provide a kind of rational in infrastructure, low cost, high-level efficiency, safely and effectively based on the portable ultrasonic surveymeter of principle of ultrasonic diffraction time difference method.
Technical solution of the present invention is:
A kind of portable ultrasonic surveymeter based on principle of ultrasonic diffraction time difference method, it is characterized in that: comprise the ultrasound emission receiver module, the ultrasound emission receiver module is connected with the analog signal processing module, the analog signal processing module is connected with the A/D modular converter, and the A/D modular converter is connected with digital signal processing module; An encoder interface circuit is connected with the coded signal processing module, and the coded signal processing module is connected with digital signal processing module; Digital signal processing module is connected with communicating circuit, and communicating circuit is connected with the embedded computer platform, and man-machine interface circuit, the network terminal, display terminal are connected with the embedded computer platform, and the embedded computer platform is connected with electric power management circuit.
The present invention is rational in infrastructure, design based on ultrasonic diffraction time difference method (TOFD) principle fully, stipulate according to industry standard, be applicable to mild carbon steel or low alloy steel material, thickness range detects at 12 millimeters～400 millimeters butt plates welding seam, is a kind of low cost, high-level efficiency, weld seam nondestructive detecting instrument safely and effectively.
The present invention adopts the structure of " PCI/104 main frame+ultrasonic circuit board ", and the instrument internal bus mode is a usb bus.The PCI/104 motherboard is selected the low-power consumption model for use, and embedded WINDOWS operating system is installed, and instrument software operates in the operating system.Ultrasonic circuit board is the professional ultrasonic circuit board of independent research, possesses functions such as ultrasound emission, ultrasonic reception, analog signal processing, signals collecting, sequential logic control, power management, usb bus communication.Carry out communication by usb bus between ultrasonic circuit board and the PCI/104 motherboard, transmission steering order and digitalized ultrasonic wave datum.
The exploitation of instrument software is based on embedded WINDOWS platform, and operation interface is attractive in appearance, easy to operate.Instrument software is operated the duty of determining instrument by the user, and operational order is sent in the ultrasonic circuit board by usb bus; Ultrasonic circuit board carries out ultrasonic excitation, ultrasonic signal reception, the pre-service such as amplification filtering of ultrasonic signal, the work such as digital collection of ultrasonic signal according to operational order, at last digitized ultrasonic signal is real-time transmitted in the PCI/104 motherboard by usb bus.The digitized ultrasonic signal that instrumentation program receives the PCI/104 motherboard (a-scan ripple) is presented on the instrument display screen in real time, and the binding site sensor data information becomes D type (or P type) scan image with a-scan ripple conversion of signals.
The present invention also is equipped with the off-line data analysis software, implements further to analyze to detecting data for the operator.Off-line analysis software can be installed on any PC with WINDOWS XP operating system, the operator derives the data of preserving in the detector and deposit in the above-mentioned PC by the network port, card reader or USB flash disk, can use off-line analysis software to analyze detecting data.Off-line analysis software provides TOFD image processing method more easily, and have software to improve gain, remove functions such as the straight-through ripple of image, the hyperbolic curve cursor that generates can help the user to measure parameters such as defect type in institute's detected object (generally being the butt plates welding seam), the degree of depth, length, height more accurately automatically.
