Abstract
The utility model discloses a roller type number scaled disc recognized by both person and computer. It includes a roller, a scaled disc with a width linearly gradual changed color strip leeching on to the roller. Ratio of the width of the color strip and the width of the scaled disc is proportional to the rotating angle of the roller in 0 to 360 degree; color on the color strip and grounding on the scaled disc are formed by two colors that could by easy recognized for computer; colors on the color strip and the scaled disc are formed the background of the scaled disc together; on color strip is provided with two color number signs which are stacked on the background formed by two colors; color on each section of the number signs is opposite to the background color. The utility model uses the method of maintaining the physical construction of the original roller type scaled disc, increasing a width linearly gradual changed color strip, and changing the color of the signs, thereby realizing the convenience for labor reading and computer recognition, a simple structure, low cost, and easy realization.
Description
One, technical field
The utility model belongs to the mechanical type instrument field that the automatic numerical value of domestic meter, gas meter, flow meter reads, in particular for people-machine universal identification drum-type numeral scale.
Two, background technology
Along with the improvement of resident family living conditions, the quantity of independent all kinds of water meters and the gas meter, flow meter of using is more and more in the every family.Manual metering work not only needs great amount of manpower, influences the rest of resident family, also occurs error easily.Therefore, by installing camera and associated electronics from the teeth outwards additional, be a kind of effective method with the automatic collection that realizes instrumented data to transform existing water meter and gas meter, flow meter.At present, the water meter that is used for the water meter automated collection systems can be divided into active formula and passive type two big classes.
Active formula water meter adopts tongue tube, Hall element to export the numeration pulse usually when water meter rotates, and calculates meter reading by the accumulative total pulse.But the shortcoming of this method is: because big or small water hammer is recurrent in water supply line, therefore, the owner is under the situation that does not have water, and the water meter pulse but constantly produces, the numeration error that is produced will add up, and it is bigger than producer's actual used water number to cause water meter to copy number; In addition, add on water meter that artificially magnet disturbs, and also can cause system inaccurate.Having the needle of some water meters to use of a specified duration exists the demagnetization phenomenon, also can influence the accuracy of system; Needing continuously, power supply could guarantee operate as normal.
Passive direct-reading water meter reads the real-time character wheel or the total indicator reading data of table tool by installing the infrared ray sensing device under the code-disc in table additional or adopting camera head after powering up under the acquired signal control.But the former must do bigger change to existing water meter structure, so the cost height; The latter is to the identification calculation of complex of existing dial scale reading, and accuracy is low, when gathering in real time to the arithmetic speed and the storage capacity requirement height of computing machine.And the reading of drum-type scale when the non-integer scale of existing water meter and gas meter, flow meter the situation of damaged and two half-words of character occurs through meeting, and the digit recognition of carrying out the scale image with existing mode identification technology is very difficult: recognizer is multiple, recognition speed is low and poor accuracy.
Three, utility model content
The purpose of this utility model is to provide a kind of existing drum-type scale physical construction of not changing, and is used for people-machine universal identification drum-type numeral scale by what increase linear gradient width colour band and adopt the dichromatism Digital ID on scale.
The technical solution that realizes the utility model purpose is: a kind of people-machine universal identification drum-type numeral scale, comprise cylinder, scale depends on the cylinder, linear gradient width colour band is set on this scale, the ratio of this colour band width and scale width is directly proportional with the cylinder corner in 0～360 degree, colour band color and scale background color are made up of two kinds of colors that computing machine is easy to discern respectively, and the color of colour band and scale constitutes the background of scale jointly; The dichromatism Digital ID is set on colour band, and this Digital ID is superimposed on the background of being made up of two kinds of colors, and the color of Digital ID each several part is opposite with backcolor all the time.
The Digital ID of the utility model people-machine universal identification drum-type numeral scale is numeral, letter or graphical symbol.
The utility model people-colour band the color of machine universal identification drum-type numeral scale and the color of scale background color are respectively black, white.
The utility model compared with prior art, its remarkable advantage is: do not change the physical construction of former drum-type scale, only realized not only convenient artificial reading but also be easy to machine recognition by the method that increases linear gradient width colour band and modified logo symbol color; Features simple structure is easy to realize; Cost is low.
Four, description of drawings
Fig. 1 is the structural representation of the utility model people-machine universal identification drum-type numeral scale.
Fig. 2 is the expansion synoptic diagram of Fig. 1.
Five, embodiment
Below in conjunction with accompanying drawing the utility model is further described.
In conjunction with Fig. 1, Fig. 2, people of the present utility model-machine universal identification drum-type numeral scale, comprise cylinder 3, scale 4 depends on the cylinder 3, linear gradient width colour band 1 is set on this scale 4, the ratio of this colour band 1 width and scale 4 width is directly proportional with cylinder 3 corners in 0～360 degree, and colour band 1 color and scale 4 background colors are made up of two kinds of colors that computing machine is easy to discern respectively, and the color of colour band 1 and scale 4 constitutes the color background of scale jointly; Dichromatism Digital ID 2 is set on colour band 1, and this Digital ID 2 is superimposed on the background of being made up of two kinds of colors, and the color of Digital ID 2 each several parts is opposite with backcolor all the time.The width of scale 4 can equate or less than the width of cylinder 3.Digital ID 2 can be numeral, letter or other graphical symbols.The color of colour band 1 color and scale 4 background colors is respectively black, white.Certainly, the color of colour band 1 color and scale 4 background colors so long as computing machine be easy to identification get final product, can be the multicolour of redness, blueness, black, white and combination in any.Linear gradient width colour band 1 is used for machine recognition, and Digital ID is used for artificial reading.Computing machine is to from scale 4 video in windows that picture pick-up device obtained, and through handling: elimination Digital ID 2 only keeps colour band 1 image; Can identify the current accurate calibration value of reading to coil easily by the mean breadth of judging colour band 1 in the window.
