Ruler 5 is vertical.Vertical scale 5 should keep vertical direction in measurement as far as possible, and laser sheet optical is normal thereto can guarantee survey
Measure the accurate of data.Light transmittance threshold range is between 0% to 45%.Light transmittance threshold value, abbreviation threshold value, the threshold range take
One section of value is it is evident that 0%, and the other end can be chosen such as 44%, 43%, 42%, 41%, 40%, 39%,
38%, 37%, 36%, 35%, 34%, 33%, 32%, 31%, 30%, 29%, 28%, 27%, 26%, 25%, 24%,
23%, 22%, 21%, 20%.Above-mentioned value has been only exemplified by the preferable particular value of some effects, however, the tool of our embodiments
Body value can also be the discrete value between above-mentioned determining integer percent, since specification length is limited, no longer enumerate.
The selection of above-mentioned threshold value can effectively be balanced between efficiency, precision.Vertical photoelectricity water sand interface detecting module is completed
After the measurement of one measurement point, photoelectricity water sand interface detecting module is moved up.The design of above-mentioned steps can effectively avoid water
Husky interface detection device is likely to be encountered higher water sand interface when moving horizontally, and then prevents from breaking measurement initial data
It is bad.It is disconnected immediately below light-path sensor, that is, optical sensor 1, in unobstructed situation, light is issued by notch one end, almost without
Enter to defect the other end, following light, which is imported into treatment box and is converted into electric signal, to be handled.When optical sensor gap segments
After being blocked by lighttight boundary material, after the light of one section of optical sensor sending is blocked, from other one section of light received
The decline of line intensity, imports the luminous intensity and the unobstructed well-illuminated intensity of light for having significant difference, passing through due to notch for the treatment of box at this time
Related with the depth that light sensor submerges bed surface, luminous flux is to gradually decrease, after optical sensor notch submerges bed surface completely,
Light passband reaches stable low value, and light passband threshold value can be set, after light passband is less than threshold value, i.e., it is believed that sensor head
Reach water sand interface location.Treatment box 2 contains power supply, photoelectric conversion and signal processing circuit module.The effect of above-mentioned module
It is to digitize signal, is used for precise alignment.Instruction device on treatment box 2 with sound and/or light.When optical sensor 1 connects
Contacting interface to be measured is, treatment box circuit drives loudspeaker 3, which makes a sound, signal lamp 4 is always on from green becomes red sudden strain of a muscle, prompts to survey
Amount personnel's sensor arrived water sand interface location, and survey crew directly reads and reads on scale at this time, and read in datum mark
Compare the water sand interface elevation that can be obtained relative to datum mark.
Original underwater topography measurement of higher degree device is obtained using the method that level reads scale above water sand interface device
Underwater topography elevation, complicated for operation, cooperation personnel are more, and technical requirements are higher.The topographic survey device is by horizontal laser light piece light
Device replaces level to measure landform, reduces technical difficulty, saves cost of equipment, and measurement is convenient and efficient, has higher
Stability, working efficiency can be significantly improved, it can be achieved that the long water lasted, the husky interface measurement of higher degree.For river work, hydraulic model side
Just, efficiently water, husky interface level measurement, enhancing measurement work mobility, flexibility improve working efficiency.
Although preferred embodiment has been combined to describe the present invention, however, it is not to limit the invention, any this field
Technical staff can implement various change to the theme listed herein without departing from the spirit and scope of the present invention
Become, the displacement and modification of coordinate, therefore protection scope of the present invention is subject to the range limited depending on the claim proposed.
