Industrial computer 3, connection data capture card 2, go forward side by side line number according to one's analysis and store in order to the voltage signal of accepting to collect.In the present embodiment, the model that industrial computer 2 adopts is D525-3.The reason that adopts industrial computer 3 rather than single-chip microcomputer of the prior art be the performance of industrial computer 3 more powerful can meet carry out operational analysis in this locality, and adopt the words of single-chip microcomputer just can be analyzed after data upload.
Power supply 4, provide electric power in order to give sensor assembly 1, data collecting card 2 and industrial computer 3.In the present embodiment, what power supply 4 adopted is battery, can facilitate like this anchorage engineering quality detector to carry out integrated moving.
Constant current source module 5, constant current source module 5 is connected between sensor assembly 1 and data collecting card 2, in order to the voltage signal that sensor assembly 1 is generated, is filtered and be sensor assembly 1 power supply, and constant current source module 5 is powered by power supply 4.In the present embodiment, the model of constant current source module 5 is CM3502, and the effect of constant current source module 5 is to provide the power supply of 4mA constant-current supply for sensor assembly 1; The tested signal for faster of interchange be superimposed upon on direct current (DC) bias that will speed up sensor assembly 1 output passes through the CR high pass every straight output, every falling direct current (DC) bias, only retains AC signal output; Can be good at like this guaranteeing that the sensor die block signal is true completely glitch-free voltage signal is sent to data collecting card 2.
Boost module 6, boost module 6 is connected between constant current source module 5 and power supply 4, in order to improve the output voltage of power supply 4.Because the output voltage of battery does not meet the input voltage standard of constant current source module 5, so being set, boost module 6 is used for improving voltage.In other embodiments, if meeting the demands, the output voltage of power supply 4 just do not need to arrange boost module 6.
Input equipment 7, input equipment 7 is connected between data collecting card 2 and industrial computer 3, in order to receive instruction.In the present embodiment, input equipment 7 is touch-screen, and in other embodiments, input equipment 7 can be keyboard or mouse etc.
Output device 8, output device 8 connects industrial computer 3, in order to output information.In the present embodiment, output device is LED display, and in other embodiments, output device 8 can be the display screen of other type.
The present invention also provides a kind of analytical approach of anchorage engineering quality detector, refers to Fig. 2, and analytical approach comprises:

Parameter specifically includes but not limited to the anchor pole type, estimates parameter of velocity of wave, design length, intended diameter and exposed junction length etc., when carrying out data analysis, the setting of anchor pole type, estimation velocity of wave, design length, intended diameter and these parameters of exposed junction length need to use, the anchor pole type can be influential to velocity of wave, estimate that velocity of wave is to also have other condition to be estimated according to different anchor pole types, thereby the effect of design length, intended diameter and exposed junction length is by analysis result and their contrasts are determined whether to meet the design needs.In other embodiments, can also input other information, for example: engineering name, anchor pole numbering, testing location, test zone, measuring unit and tester etc., these information can conveniently be added up and be managed last data.
Step S2: data acquisition;
Data acquisition can gather the complete data analysis that enters again afterwards to many anchor poles successively.
Step S3: local data analysis;
In this locality, directly to data analysis, the step of concrete analysis comprises: in this locality, make energy calculation, phase analysis, digital filtering, frequency-domain analysis, wavelet analysis, the time length of field, frequency domain length, defective locations calculating, packing analysis, inverse velocity of wave and vernier tuning.
Step S4: data upload;
Upload the data on PC, the mode of uploading can be various, can PC and anchorage engineering quality detector is direct-connected, also can be transported by storage medium, such as: USB flash disk, portable hard drive etc.
Step S5: data analysis on PC; Step S5 comprises:
Step S51: select file to be analyzed;
Step S52: the contrast Wave data, select certain Wave data analysis;
Step S53: the analyzing and processing of selected certain wave file being carried out to respective algorithms;
Step S54: analyzed, form is set, the printed report file.
After uploading on PC, can conveniently carry out more complicated analysis and calculation, also facilitate the preservation of data.But, in the time only need to carrying out simple analysis, can not uploaded directly and be completed in this locality.
Below take the present embodiment as example describes in detail principle of work of the present invention.
Refer to Fig. 4, while being detected, by the sensor probe of sensor assembly 1 11 contact measured anchor poles, operating personnel use hammer to knock anchor pole to be measured and make anchor pole vibration to be measured, sensor assembly 1 is experienced vibration degree of will speed up shock wave and is converted voltage signal to, data collecting card 2 is sent to voltage signal acquisition on industrial computer 3, and industrial computer 3, directly to data analysis, can shift data to upload on PC by USB flash disk after analysis and further analyze.
In sum, the present invention completes in local data analysis by industrial computer, has avoided uploading the data to the trouble of PC, thereby has improved the work efficiency detected.
The foregoing is only better possible embodiments of the present invention, not limit the scope of the invention.Every equivalent structure or conversion of equivalent flow process that utilizes instructions of the present invention and accompanying drawing content to do, or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
