Abstract
The present invention relates to the tap water facility field, especially to a reflective gauging table. The reflective gauging table comprises a housing and a plurality of print wheels. There is a linearity CCD installed between the housing and the print wheels, and the print wheels are provided with digital blocks and a five-bit Gray code area. The five-bit Gray code area comprises five circles of coding areas, each comprising 24-degree shadow region, a 60-degree clear region, a 96-degree shadow region, a 24-degree clear region, 60-degree shadow region and a 96-degree clear region arranged in order, each 12 degrees is correspondingly provided with a binary digit coding, the shadow region coding is 0, the clear region coding is 1, and from the left to the right, in the five circles of the coding areas, the coding areas at the left rotates 36 degree in the clockwise direction to obtain the coding areas at the right. Because the linearity CCD is assembled, the reflective gauging table is simple in technology, simple to assemble, easy to operate, low in cost and high in precision.
Description
Technical field
The present invention relates to originally drainage facility field, more particularly to a kind of reflective gauge table.
Background technology
Under current technology, all functions with direct-reading teletransmission such as combustion gas and water, ammeter, it is no longer necessary to which the person of checking meter is from house to house
Manual metering, the sensor that need to be only arranged on table can teletransmission input computer.It is generally used for the flows such as metering air-liquid, electricity
Gauge table, its operation principle is by the detection flows device in instrument, detection flows device band by air-liquid, dielectric
Dynamic transmission device, then drive reading disk to rotate by transmission device, when character code is set on reading disk, by reading disk
Amount of spin reflected by character code.But, the gauge table under current technology is smaller due to giving available angle, and people make not
Go out the accurate gauge table of readable, great inconvenience is brought to user and company；This mode is typically all by 5 simultaneously
Sensor determines the numerical value of this character wheel, because a disk has 360 °, 5 sensor devices can be only placed at character wheel because space is limited
180 ° of cambered surface, 5 sensor one character wheel costs of correspondence are higher, and 5 sensor equalizations are placed on 180 ° of cambered surfaces, identification
Scope is smaller, causes read untrue, accumulates over a long period and may result in bigger mistake.
The content of the invention
A kind of defect in order to make up prior art of the invention, there is provided reflective gauge table that pin-point reading can be provided.
The present invention is achieved through the following technical solutions：
A kind of reflective gauge table, including shell and some character wheels, it is characterized in that：Install linear between the shell and character wheel
CCD, the character wheel is provided with digital block and five Gray code areas, and five Gray code areas include five circle code areas, and each circle is compiled
Code area includes the 24 ° of shadow regions, 60 ° of clear areas, 96 ° of shadow regions, 24 ° of clear areas, 60 ° of shadow regions, the 96 ° of blank that set gradually
Area, every 12 ° are correspondingly arranged a binary digital encoding, and shadow region coding is respectively 0 and 1 or 1 and 0 with clear area coding,
In five circle code areas, from left to right see, the code area on the left side turns clockwise the code area obtained after 36 ° on the right of it.
The character wheel quantity is 4-8.
The beneficial effects of the invention are as follows：
The present invention assembles simple, easy to operate, low cost, precision due to being assembled with linear CCD, high resolution, and process is simple
It is high.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is main view of the invention, perspective structure schematic diagram；
Fig. 2 is the deployed configuration schematic diagram of character wheel；
Fig. 3 is the left view structural representation of character wheel.
In figure, 1 shell, 2 character wheels, 3 linear CCDs, 4 digital blocks, 5 five Gray code areas, 6 24 ° of shadow regions, 7 60 ° of blank
Area, 8 96 ° of shadow regions, 9 24 ° of clear areas, 10 60 ° of shadow regions, 11 96 ° of clear areas.
Specific embodiment
Accompanying drawing is specific embodiment of the invention.As shown in Figure 1 to Figure 3, the He of this kind of reflective gauge table, including shell 1
4-8 character wheel 2, is provided with linear CCD 3 between shell 1 and character wheel 2, and each character wheel 2 is designed with digital block 4 and five Grays
Code area 5, five Gray code areas 5 include five circle code areas, and each circle code area includes 6,60 ° of the 24 ° of shadow regions sky for setting gradually
7,96 ° of white area, 8,24 ° of shadow region, 9,60 ° of clear area, 10,96 ° of shadow region clear area 11, every 12 ° are correspondingly arranged a binary number
Word is encoded, and often encloses 30 codings, if shadow region is encoded to 0, then clear area is encoded to 1, if shadow region is encoded to 1, that
Clear area is encoded to 0, and below as a example by " shadow region is encoded to 0, then clear area is encoded to 1 ", 24 ° of shadow regions 6 are corresponding to be
00,60 ° of clear area 7 is corresponding be 11111,96 ° of shadow regions 8 it is corresponding be 00000000,24 ° of clear areas 9 it is corresponding be 11,
60 ° of shadow regions 10 are corresponding be 00000,96 ° of clear areas 11 it is corresponding be 11111111；Every three binary digits correspondence one
The numeral of digital block 4；In five circle code areas, from left to right see, first left code area turns clockwise 36 ° and obtains its right side
Second code area on side, second encoder is turned clockwise 36 ° and obtains the 3rd code area again, and the 3rd code area is revolved again
Turn 36 ° and obtain the 4th code area, the 4th code area rotates 36 ° and obtain the 5th code area again.
Linear CCD can be transformed into digital information in gathered data according to the black and white coding for collecting.Such as digital block
4,1 correspondence, three groups of black and white coding on middle character wheel, respectively " 01100,01110,11110 ", adjacent encoder only have at one it is different simultaneously
And have continuity, and when low level character wheel is from 9 to 0 carry, only one of which BIT change, root during high-order character wheel code change
It is 0 or 9 according to low bit readings, judges whether carry completes, the BIT of high-order character wheel coding can be modified.
In addition to technical characteristic described in specification, remaining technical characteristic is technology known to those skilled in the art.
