Abstract
The utility model discloses a shooting meter reading device with an airtight drying cover, which solves the problems that moisture content is condensed into dew caused by the lack of an arid region when image sensors are adopted for reading meter at present, the image sharpness is influenced and the mistake of decoding is caused; the device has the advantages of simple structure, convenient use, preventing the moisture content from condensing by arranging a dry airtight space between the image sensor and water gauge glass and improving the accuracy of reading, etc. The structure of the device comprises a meter shell which is equipped with the water gauge glass; a transparent cover is installed on the meter shell and is internally provided with the image sensor which is corresponding to the position of a counter arranged under the water gauge glass, the dry airtight space is arranged between the transparent cover and the meter shell as well as between the transparent cover and the water gauge glass; the relative humidity of the air inside the dry airtight space is less than 30 percent RH.
Description
Technical field
The utility model relates to a kind of flow instrument that utilizes imageing sensor to gather meter reading, relates in particular to a kind of camera shooting meter device that can be used for the band close drying cover of measuring instrument such as water, electricity, gas.
Background technology
At present, the mode of artificial visual, hand-kept is still adopted in most of water meter copy readings, and meter reading efficiency is low, poor accuracy, can not adopt automatic information processing etc., is the meter reading method that falls behind.Though the ordinary electronic remote transmitting water meter is advanced, the restriction of condition such as also being subjected to must uninterrupted power supply, can not break accidentally.For this reason, many designers have adopted imageing sensor, and by to water meter mechanical reading pickup image, the mode of carrying out image decoding, data processing then obtains meter reading, thereby reaches the purpose of automatic data logging.For example: existing patented technology 03128170.2,200420032402.1,200620068530.0 etc.Yet these technology are all less than set up region of no pressure or dry section between imageing sensor and water meter mechanical digital.Like this, in water meter meets cold outside the temperature difference such as heat when changing, airborne moisture will accumulate in the outer surface of water meter sight glass, even this space seals between imageing sensor and the water gage glass, so long as normal air, the capital phenomenon of hydrogenesis Cheng Lu occurs at the water gage glass outer surface, just in time blocks the mechanical reading of water meter.This block do not influence generally speaking visual check meter or camera shooting meter after manual record, but if the image that imageing sensor obtains will be translated into digital code by software, situation has just differed widely, because imageing sensor does not have this recognition capability, rarer dewfall will cause the decoding serious mistake.
Summary of the invention
The purpose of this utility model is exactly to cause hydrogenesis Cheng Lu because of lacking region of no pressure or dry section in order to solve present employing imageing sensor and to check meter, the problem of the normal shooting decoding of influence, provide a kind of have simple in structure, easy to use, a vacuum or drying sealed space are set between imageing sensor and water gage glass, to prevent the water segregation junction, improve the camera shooting meter device of the band close drying cover of advantages such as accuracy of reading.
For achieving the above object, the utility model adopts following technical scheme:
A kind of camera shooting meter device with the close drying cover, it comprises watchcase, which is provided with water gage glass, translucent cover also is installed on the described watchcase, be provided with in the translucent cover and the corresponding imageing sensor in water gage glass counter position, below, be dry confined space between translucent cover and watchcase and water gage glass, the relative humidity of middle gas is less than 30%RH between dry sealing.
Described translucent cover is an open type, and its periphery is fixed by gland and watchcase, is provided with sealing ring between translucent cover periphery and water gage glass simultaneously.
Described translucent cover is a self-closed type, and its periphery is fixed by gland and watchcase.
Described translucent cover periphery is fixed by gland and watchcase, is provided with drier in the dry confined space.
The technical solution of the utility model has two kinds, and a kind of is that the moisture air that contains in the confined space between imageing sensor and the water gage glass is taken away, perhaps whole manufacturing process is placed under the dry environment and carries out, promptly form relatively dry the space.Another kind is with putting into drier in this confined space, with water adsorption.The air of interior volume must be vacuum or dry like this, and it is worked as when the temperature difference being arranged inside and outside the water meter, and the moisture in the space between imageing sensor and the glass is unlikely to concentrate on glass surface or the imageing sensor, blocks reading.
The beneficial effects of the utility model are: simple in structure, can solve easily because of condensation vapor cause not fogging, the difficult problem of decoding error.

Fig. 1 is a translucent cover open type dry place frame mode;
Fig. 2 is a translucent cover self-sealing dry place frame mode;
Fig. 3 is a close drying agent formula dry place frame mode.
Among the figure: 1. image sensor, 2. translucent cover, 3. water gage glass, 4. mechanical digital, 5. gland, 6. watchcase, 7. dry confined space, 8. sealing ring, 9. drier.
Embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment.
Embodiment 1:
Among Fig. 1, are translucent covers 2 of open type on the top of watchcase 6, the periphery of translucent cover 2 connects firmly by gland 5 and watchcase 6.Translucent cover 2 periphery is provided with sealing ring 8 with 3 of water gage glasses, and 3 of translucent cover 2 and water gage glasses just form a dry confined space 7 like this, between drying seals in 7 the relative humidity of gas less than 30%RH.Top and the counter below the water gage glass 3 at translucent cover 2 is that corresponding place, mechanical digital 4 positions is provided with imageing sensor 1 simultaneously, is used for reading.
Embodiment 2:
Among Fig. 2, are self-closed type translucent covers 2 on the top of watchcase 6, the periphery of translucent cover 2 connects firmly by gland 5 and watchcase 6.Be dry confined space 7 in the translucent cover 2, the relative humidity of middle gas is less than 30%RH between dry sealing.Because this translucent cover self has sealing, in processes such as installation, dismounting, do not influence its inner aridity, top and the counter below the water gage glass 3 at translucent cover 2 is that corresponding place, mechanical digital 4 positions is provided with imageing sensor 1 simultaneously, is used for reading.
Embodiment 3:
