The underwater supporting block levelness detection device comprises an inclination sensor and a liquid level sensor, which are arranged on the surface of an underwater supporting block to be detected for detecting an inclination angle and depth, wherein an inclination angle signal output by the inclination sensor and a depth signal output by the liquid level sensor are output to a computer through a receiving module and a signal conversion module to store the data and display the data through display software. According to the detection device and the method provided by the invention, not only the measurement accuracy and the reliability are greatly improved, and whether a detected object is installed in place is quickly and accurately detected, but also the measured data can be recorded as an adjustment basis.
Description
Technical field
The present invention relates to the detection of a kind of levelness and the degree of depth, in particular, relate to a kind of to the levelness of the submerged structure that can not directly contact and the pick-up unit and the method for elevation.
Background technology
At present, traditional interim under water back-up block levelness detection is to extrapolate levelness and elevation through calculating wirerope displacement.But since the deviation that wirerope is installed with flexible, cause easily measuring error big, lack reliability.Native system adopts double-axis tilt sensor and high-precision liquid level sensor, can improve the precision and the fiduciary level of measurement greatly.
Summary of the invention
The present invention is directed to the defective that exists in the above-mentioned prior art; A kind of levelness detecting device of back-up block under water and method are provided; Measuring accuracy and fiduciary level have not only been improved greatly; Measure measured object quickly and accurately and whether be in place, simultaneously measurement data record is got off, with foundation as adjustment.
For achieving the above object, the technical scheme that the present invention adopts is following:
A kind of levelness detecting device of back-up block under water; Said device comprises inclination sensor and the liquid level sensor that is placed on back-up block to be measured surface under water, is used to detect its inclination angle and the degree of depth; The depth signal of the dip angle signal of said inclination sensor output and the output of said liquid level sensor outputs on the computing machine through receiver module and signal conversion module, and the preservation data also show through software for display.
The analog voltage signal of said inclination sensor output is after signal condition module conditioning, and the A/D through single-chip microcomputer converts needed digital signal into again, through respective algorithms, and the output dip angle signal, this signal is transferred to receiver module again.
Said signal condition module comprises reference voltage chip and deflection voltage chip; The reference voltage chip is adjusted to high-precision 5V reference voltage with the 5V input voltage; The analog voltage signal and the 5V reference voltage of inclination sensor output are nursed one's health 0～5V with the analog voltage signal of-2.5～2.5V behind the deflection voltage chip, convert needed digital signal into through single-chip microcomputer again.
The transmission of said signal is transmitted through communication cable.
A kind of levelness of back-up block under water detection method may further comprise the steps:
Step 1: the liquid level sensor that will be used to measure water level earlier is fixed on specified point, and this point can provide the elevation of local coordinate and write down the distance of specified point to the measure portion of liquid level sensor;
Step 2: with inclination sensor with measure under water the liquid level sensor of back-up block and be placed under water and gather the multiple spot data on the back-up block;
Step 3: measure and to finish, sensor signal is outputed on the computing machine through handling, preserve and show.
The beneficial effect that technical scheme of the present invention is brought:
Adopt inclination sensor and liquid level sensor as measurement module; Communication cable, signal condition module, receiver module and signal conversion module are as communication media; Computing machine is as measurement display unit; Whether the installation that can detect interim lip block meets the requirements, simultaneously through the three-dimensional picture attitude that shows interim lip block directly perceived.
System and method of the present invention and traditional measurement mode specific energy mutually improve detection efficiency, promptly reduce frogman's activity duration under water; Improve measuring accuracy, the incline measurement error is less than 0.1 degree, and vertical error is no more than 1cm; Convenient measurement, the frogman need not write down any data during measurement, the mistake of having avoided human factor to cause, the frogman can carry out other operation under water simultaneously.
Description of drawings
Below through accompanying drawing technical scheme of the present invention is done and to be described in further detail:
Fig. 1 is a system chart of the present invention;
Fig. 2 is a signal condition module composition frame chart among Fig. 1.
Embodiment
In Fig. 1; The analog voltage signal of inclination sensor 1 output, convert the analog voltage signal of 0～5V into through signal condition module 3; A/D through single-chip microcomputer 4 converts digital signal into the analog voltage signal after the conversion; Pass through corresponding algorithm simultaneously, the output pitch angle passes to computing machine 7 with the depth signal of liquid level sensor 2 outputs and the dip angle signal after single-chip microcomputer 4 processing through receiver module 5 and signal conversion module 6 at last.
Signal condition module shown in Figure 2 comprises reference voltage chip 8 and deflection voltage chip 9.At first with obtaining high-precision 5V reference voltage behind the 5V input voltage process reference voltage chip 8; Its initial precision is 2.0mV; The output analog voltage signal of inclination sensor 1 and reference voltage are nursed one's health 0～5V through deflection voltage chip 9 with the analog voltage signal of-2.5～2.5V then, convert needed digital signal into through single-chip microcomputer 4 again.
Below for an embodiment of technical scheme of the present invention:
Fathoming of a certain moment liquid level sensor 1 is h
1, fathoming of liquid level sensor 2 is h
2, then we can to obtain measurement point elevation this moment be H
0-(L-h
1)-h
2This is θ x, the θ y of inclination sensor through obtaining after the handled in horizontal and vertical pitch angle of measurement point constantly.As required, acquisition time can be set, consider the response time and the measuring accuracy of liquid level sensor, data acquiring frequency is less than 0.1Hz.There is grains of sand in the actual measurement because the surface that the temporary support cushion block is placed or receives influence such as current, and measurement result has small variation, and this also can get off through software records.In 0.1 degree, vertical error is no more than 1cm (not considering the influence that wave brings) to present embodiment to interim back-up block incline measurement error.
