Method, this method monitor system using the combination 3D printing and the pile body shifting of wireless Flex sensings of the above embodiment, specifically
Include the following steps：
Step 1：Assemble deviational survey sensor
First according to the object of detection to Flex sensors carry out size design, mainly include each PLA pipes length and width and
Quantity, and CATIA Software on Drawing is used, with 3D printer printing (including interconnecting piece, the PLA with mounting groove are managed).It has printed
It is assembled after, and Flex sensors is placed in the PLA pipes of mounting groove, each segment PLA pipe groups are hingedly made by interconnecting piece
A long tube is dressed up, big sensor is formed, mobile inclination measurement device is finally packaged protection, takes test point to.Take inspection to
After measuring point, long tube is inserted into the preformed groove 2 of reinforced concrete pile 1 to be measured, then be in the milk with concrete, makes long tube is opposite to wait for
Reinforced concrete pile is surveyed no longer to relatively move.
Step 2：Detecting system is tested：
Data collector (i.e. FLEX sensors) and data receiving terminal are established by SIM800C mobile data modules (i.e.
PC or cell-phone customer terminal) wireless connection, monitoring data are carried out using corresponding driving operating software in PC or cell-phone customer terminal
Record and analysis.
Step 3：Calibration experiment obtains the relationship between corner and sensing data by calibration experiment.According to sensor
Registration changes over time, and the wireless sensor registration and angular relationship obtained using calibration experiment is extrapolated by gathered data
Angle change realizes deviational survey.In addition to this, the size of itself can be also managed according to angle change and PLA, extrapolate determinand along certain
The change in displacement in direction.Calculating often there emerged a monitoring point gradient or displacement changes with time, and paints related charting, realization is treated
Survey the purpose that object monitors in real time.It is specific as follows：
(1) calibration experiment obtains rotational angle (θ) by experiment --- relationship θ=f (x) between the data (x) of collection.
(specific experiment can be because of the influence of the difference and other factors of sensor, and result that may be last is different, herein just no longer
Provide physical relationship.)
(2) after sensor being placed, it is assumed that lower end is motionless, and upper end deforms to the right (as shown in Figure 3) with stake.1 angle of pipe
Variation is a, and 2 angle change of pipe is β, and it is respectively x that mobile phone terminal, which receives the sensor registration that at pipe 1 and pipe 2 is arranged,1And x2,
It brings angle into θ=f (x), obtains corner occurrence a=f (x1) and β=f (x2), to obtain the variation of angle, i.e., stake is at this
It measures at the inclination angle at place.
(3) change in displacement can also be measured according to simple geometric knowledge in addition to inclination angle：Assuming that No. 1 pipe range is L1, No. 1
Pipe range is L2, then original vertical extension L is L=L1+L2.Deformed vertical extension L ' is L '=L1cos(a+β)+L2cos
β.Vertical displacement Δ L is Δ L=L-L ', i.e. Δ L=(L1+L2)-{L1cos[f(x1)+f(x2)]+L2cos[f(x2)], i.e., it is logical
Cross the registration x measured1、x2It can be obtained vertical displacement.
(4) similarly, the displacement of horizontal direction can also be calculated.
It is not difficult to find that the present invention manages using the PLA of 3D printing technique printing preformed groove, connects the hinge of several PLA pipes；Pass through
Flex sensors are fixed on the inside by the preformed groove of two stands plate, and the deformation of stake makes sensor be rotated along hinge, and different deformations makes
The angle of holder pivots is different, to realize the measurement to suffered bending degree (or change in displacement).The sensor herein in connection with
GPRS technologies realize the remote real-time Transmission of data, and realize monitoring in real time by cell-phone customer terminal.Actual measurement 3D printing energy
Enough printing and makings for completing each component faster only need to be assembled simply without other mechanical processings, facilitate volume production.
