Direct-reading camera 16 is equipped at the top of the overflow cylinder 3, the direct-reading camera 16 is electrically connected with microcontroller 9
It connects.
The evaporation stylus 4 is that stainless steel evaporates stylus.
Workflow: firstly, driving 5 quick rotation of adjusting knob by motor 7, when turning to the water surface, the water surface can be open circuit
Evaporation stylus turn-on power, stop operating at this time, round about turning knob, leave the water surface at this time, motor starts again at
It rotates down, but at this time with the rotation of most jogging speed, when open circuit is connected, and contacts the water surface, stop operating motor.
Secondly, when determining that microcontroller 9 controls industrial camera starting, while starting searchlight to after front evaporator water level
11, two photos are then shot, are achieved, and start the analysis program on microcontroller.
Finally, automatically forming eight-level code message after parser analysis goes out current actual numerical value, being passed by GPRS module
It send to regimen center.
Microcontroller 9 uses LATTEPANDA, which pre-installs complete Windows 10, built-in a series of comprising Visual
Tool including Studio, Java ensure that its operational efficiency and the quality of operation, very practical.From the aspects of configuration,
It carries four core 1.8GHz processors, possesses 2/4GB RAM and 32/64GB EMMC and stores, facilitates people's store files, and
It supports WiFi, bluetooth, and function is relatively more.
Reading data Software Development Platform: Visual Basic 6.0, by Picture control, to picture by pixel into
Row tertiary treatment.
Coagulation: carrying out pixel optimization to original image, mainly carries out pixel to image of taking pictures and is spliced again,
Original image background colour canescence, red is converted into so as to effective district background parts；Then the Point function of Picture control is utilized
It can be carried out the value for differentiating each pixel, value similar in picture pixels point can be tuned into one kind, the vivid degree of image can be reduced in this way,
Image pixel type is allowed to reduce, human eye seems bright not as good as original image, but reading difficulty is exactly reduced for computer, than
It is exactly to eliminate bloom part Ru most functional, region similar in original image is joined together, we test empirical value and generally set
For pixel color difference 115, the image color after this function treatment obtains graduation mark than reinforcing, convenient for the later period.The grade treated figure
As the synchronous PEN function by Picture control is painted into two stage treatment frame.
Two stage treatment: first removing original image background, and general default takes color from the 100th, 100 point, such as identical continuous color
Color then remove, difference is regarded as background colour within value of chromatism, and color difference can be manually arranged for the first time, is changed to pure white, with
Indicate blank；Back can thus be cancelled to affect.Then graduation mark is handled, dark can be modified to black, in this way
The figure repaired can take color tool to take the color of certain point by program, and when if it is not being background color value, continuation is read to the right,
When there is non-background color in the row line, then it is assumed that the row is a graduation mark；Continue next line, successively obtains the color of each point
Value, if being still non-background color, then it is assumed that the row is still the scale of uplink, when the same for background colour, then it is assumed that the degree
Item terminates, and can thus sequential read out the position of each scale strip；And current level principle is identical, only lines are from left to right to compare
Wider line is waterline；In order to improve acquisition speed, a point can be taken every 10 pixels, not influence thus to last read knot
Fruit；Furthermore background colour and scale color can be set in order to fit the graduated scales of the various colors of row when initialization is arranged in software, when
When mouse obtains certain point, the automatic color-values for detecting current point are manually set to initial background color or quarter with this color put
Spend color.Same graduated scale does not need to repeat to be arranged.Treated that image is put into tertiary treatment frame for the grade；Due to the ruler class
Type is that left and right divides type equally, and there are scale in two sides, therefore we only use left side half image.
Tertiary treatment: being finally the processing of scale, color may be thinner for human eye in figure, but for picture
Vegetarian refreshments for the computer distinguished, is just suitble to read scale number of lines, such as is read out from X-coordinate, until the non-bottom of appearance
When color, it is believed that the row starts, if not having foreground numerical value in 3 times of step-lengths, then it is assumed that the knot beam；Step-length is settable.
Take 3 times of step-lengths purpose be to prevent there is partial pixel point to be in preposition processing, lines be not entirely it is continuous, when having variegated at
Manage into background colour.It is worth noting that, no matter lines length is not necessarily to be concerned about for we calculate, because of long lines short line
Between be 1mm, so we only need line taking item occur number, occur several lines be then which millimeter, water level line ratio
It is easier to judge, judgment mode is exactly that the lines from left side close to the leftmost side are water level position.
For convenience of installation and outdoor long-time service, evaporator 1 and overflow cylinder 3 are acrylic material.
To improve current level position clarity, the thin oilpaper of black can be cut into circle, be put in acrylic evaporator
In, it is floated with water, improves the clarity of watermark.
Using technical solution described in the utility model or those skilled in the art in technical solutions of the utility model
Under inspiration, similar technical solution is designed, and reaches above-mentioned technical effect, is the protection model for falling into the utility model
It encloses.
