Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples, the embodiment is practical for explaining
It is novel, rather than the limitation to scope of protection of the utility model.
(1) the horizontal vertical displacement monitors structure and working principle of ground fissure
As shown in Figure 1, the horizontal vertical displacement monitors of ground fissure described in the utility model include long inserted sheet 1, short inserted sheet 2,
Reflector 3, laser sensor 5, data collection module 7 and computer 8, wherein laser sensor 5 passes through a data line 6 and data
Collection module 7 connects, and data collection module 7 is connect by another data line 6 with computer 8, and laser sensor 5 throws laser 4
It is incident upon on the laser reflection target being made of reflector 3, long inserted sheet 1 and multiple short inserted sheets 2.
Referring to fig. 2, in the laser reflection target, adjacent inserted sheet (between long inserted sheet and short inserted sheet, short inserted sheet) interval can
It is needed according to actual displacement measurement accuracy and the adjustment of the susceptibility of laser sensor, long inserted sheet 1 is located on all short inserted sheets 2
Side.Laser sensor 5 projects horizontal direction laser 4, is incident upon on laser reflection target, as laser sensor 5 and laser are in target
The variation of distance between the launching position in face, laser sensor 5 generate corresponding detection electricity according to the reflected light signal received
(distance is bigger, then it is smaller to detect voltage for pressure；It is described then to detect that voltage is bigger apart from smaller, that is, there is certain ratio and closes
System, specific proportionality coefficient can be demarcated at the scene according to specific equipment), so as to realize ground fissure horizontal displacement
Measurement.With laser sensor 5 and the relative motion of laser reflection target, keep the launching position of laser 4 two neighboring slotting from being located at
Between piece or some inserted sheet side, then when being projected on long inserted sheet 1 or short inserted sheet 2, cause laser sensor 5 and laser in target
Distance between the launching position in face is substantially reduced and (causes to detect voltage jump, that is, significantly increase), and multiple inserted sheets are equivalent to
Scale on one graduated scale, so as to realize the measurement of ground fissure vertical displacement (number of division is mutated number).
Laser reflection target and laser sensor 5 are arranged in ground fissure two sides, make the relative motion and ground fissure of the two
Activity it is corresponding, so as to using on laser sensor projection laser 5 to laser reflection target, to obtain ground fissure activity letter
Breath, data collection module 7 collect laser sensor 5 and detect signal and be transmitted to computer 8, then can give birth to by computer 8
At the movable image of reflection ground fissure and the horizontal and vertical displacement variable of ground fissure is calculated.
(2) ground fissure monitors applicating example
Laser sensor 5 uses Panasonic HG-C1020, and laser sensor 5 detects signal and adopts through YAV USB analog data
Collection module (as data collection module 7) acquires and is transmitted to computer 8, and detection signal passes through the YAV high installed on computer 8
The processing of precision UMS software.In laser reflection target, 0.5cm is divided between adjacent inserted sheet, wherein long inserted sheet 1 is from reflector 3 along water
Square to extend outwardly length be 3cm, each short inserted sheet 2 from reflector 3 extend outwardly in the horizontal direction length be 1cm.
The upper disk of ground fissure persistently cracks (horizontal displacement increase) and with sinking, is inserted to ground vertically using bottom before monitoring
Crack side (upper disk) 3 fixed laser of reflector reflection target (specific fixed position when considering soil stabilization as far as possible
Close to ground fissure), laser sensor 5 is placed in the ground fissure other side (lower wall) and is fixed.Initial time is monitored, laser is passed through
The laser 4 that sensor 5 issues is incident upon 2 downside of the short inserted sheet of basecoat on reflector 3, with the short inserted sheet 2 apart from for 0.5cm
(more accurately to measure vertical displacement), with moving horizontally for ground fissure, the voltage change figure that is recorded in real time on computer
As voltage signal changes gradually downward at any time in (waveform diagram in Fig. 3)；If ground fissure while horizontal direction is mobile along with
Vertically movable, then reflector 3 is moved down with the activity of ground fissure, is formed at this time due to having on reflector 3 by each inserted sheet
Lattice-shaped convex-concave construction, laser 4 is per a scanned inserted sheet (such as short inserted sheet 2), the voltage that records in real time on computer 8
Modified-image will occur once to be mutated that (detection signal is corresponding apart from the distance of laser sensor to the inserted sheet, and direct upwards
Project the inserted sheet corresponding position on reflector to compare, distance reduces suddenly, and detection signal is caused to increase suddenly), referring to
Two sections being mutated upwards in left side in Fig. 3 waveform diagram；When the inswept long inserted sheet 1 of laser, similar mutation also occurs for detection voltage,
But since long inserted sheet is obviously greater than short inserted sheet in protruding length, the mutation of signal is detected as caused by long inserted sheet
It is bigger, and reach the upper limit of voltage change image, referring to the larger catastrophe point of the rightmost side in Fig. 3 waveform diagram；Detect sign mutation
Size can be distinguished with the difference in length of line segment vertical in Fig. 3 waveform diagram.Due on reflector 3 between inserted sheet and inserted sheet
Distance is certain, it is possible to which calculating ground fissure vertical displacement according to mutation frequency n is n × 0.5cm.
When horizontal displacement or vertical displacement reach preset maximum value (this maximum value can be arranged in computer 8), meter
Calculation machine automatic alarm (the right side alarm region in Fig. 3 is displayed in red mark)；If not up to preset maximum value records data,
To realize the function of monitoring and alarm.
By the record of Fig. 3 as a result, choosing sampled point according to a certain percentage, and according to the relationship of voltage and actual range into
Row pretreatment, can be obtained at the sampled point of selection that laser sensor is at a distance from target, with the progress of monitoring, computer is defeated
Image format shown in Fig. 4 out can more intuitively reflect that the displacement of ground fissure changes with time situation.It is not mutated in Fig. 4
The upward variable quantity of section corresponds to the increase of horizontal displacement, and vertical displacement is obtained by the analysis of mutation section number.
The utility model can use single laser sensor and complete monitoring, not only simplify equipment by the target,
The complexity of lowering apparatus operation, moreover it is possible to the image that target co-ordinates variation is converted to reflection change in displacement, to the hair of ground fissure
Exhibition situation is intuitively shown, the working efficiency of the horizontal and vertical displacement monitoring of ground fissure is remarkably improved.
