Description
Technical field
The present invention relates to a kind of photoelectric direct-reading water meters, more particularly to a kind of anti-bubble photoelectric direct reading remote transmission water meter.
Background technique
Photoelectric direct-reading water meter is that the outer rim in the character wheel of counter printing position 0-9 of common water meter prints specific markers,
The fixed photoelectric sensor in its periphery and interlock circuit.When external power supply meter reading, specific markers " having " is judged by photoelectric sensor
With the state of "None".Photoelectric direct reading remote transmission water meter is therefrom found out unique by being calculated by combination to character wheel founding mathematical models
Then correctly solution prints specific label according to mathematical law on the corresponding position of character wheel 0-9 again, according to number around it
It learns rule and fixed photoelectric sensor is installed again, thus a mathematical problem is realized by electronic circuit method.It examines simultaneously
Consider the algorithm of various fault-tolerants, error correction, so that it may obtain unique correctly solution --- unique data i.e. on character wheel.
The characteristics of photoelectric direct reading remote transmission water meter, is: 1), directly reading counter encoder digital i.e. " window value " that table has, table
Interior no setting is required parameters such as the table truth of a matter, table constant are not necessarily to storing data, and cumulative errors are not present, are truly realized " meter reading ", tie
The history of beam accumulated pulse, the numerical value that converts.Direct-reading gage tool electronic section and table have in the devices such as counter be kept completely separate, do not have
There is Mechanical Contact, does not influence measuring accuracy.2), direct-reading remote installed meter directly transmits data, and non-pulse signal.It is not only by machine
Tool vibration influence, while also there is high anti-interference to electromagnetic interference, so can stablize under complicated use environment, is quasi-
Really, it is reliably achieved metering.3), due to direct-reading remote installed meter acquisition be mechanical counter character wheel position (and non-pulse), because
When this table tool occurs to reverse situation, reading of the meter reading data still with table tool is consistent.
Direct-reading gage in this way mainly has photoelectricity to penetrating (transmission) formula and two kinds of photo-electric reflection type at present, main
Difference is the difference of mechanical structure and mathematical algorithm.Photoelectricity can be only applied to dry-type meter to penetrating (transmission) formula technology, and light
Galvanic reflex formula technology can be applied not only to dry-type meter, and can be applied to liquid-seal water meter.In wet-type meter fluid-tight box
Be easy to produce bubble, especially on encoding strip or in coding slot there are when bubble, the appearance when light that light-emitting tube issues passes through
Phenomena such as being also easy to produce refraction reduces the luminous intensity for being irradiated to photosensitive receiving tube, so that the induced current of photosensitive receiving tube reduces,
Sensor code error is caused, causes to interfere the error in reading generated due to bubble；It is interfered for bubble, industry is not yet at present
Effective method, due to the limitation of bubble interference, so that the popularization of photoelectric direct reading wet type water meter has very big bottleneck.
Summary of the invention
It is handled, is resisted by hardware auxiliary and software it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of
The significantly anti-bubble photoelectric direct reading remote transmission water meter of bubble interference effect.
The purpose of the present invention is achieved through the following technical solutions: anti-bubble photoelectric direct reading remote transmission water meter, including vibration
Dynamic motor, direct-reading processor and camera, camera are set to above dial plate, and camera is for shooting pointer on water meter dial plate
Image is read, anti-bubole analysis module is provided in direct-reading processor, anti-bubole analysis module is for extracting in reading image
Characteristic information, and bubble is judged whether there is according to this feature information, when being judged as there is no when bubble, is read and schemed with the moment
Numerical value as shown in is water meter reading numerical value；When being judged as there are when bubble, direct-reading processor issues driving signal triggering vibration horse
Up to running, and the reading image that bubble is clearly not present is captured during vibrating motor running, which is shown
Numerical value obtains the moment water meter reading numerical value by vibration compensation.
The determination of vibration compensation: starting vibrating motor under perfect condition (bubble is not present), under a certain vibration frequency,
The water meter reading numerical value measured when by vibration is compared with practical water meter reading numerical value, and the error in reading obtained under the vibration frequency is closed
System, obtains the design parameter of vibration compensation with this error in reading relationship.
The beneficial effects of the present invention are: being turned in image recognition to vibrating motor is started automatically in the presence of having bubble with vibration
Bubble position is moved, the reading image that bubble is clearly not present is captured in the process, and vibration compensation is carried out to the reading, mentions
High accuracy of reading, anti-bubble interference effect is obvious, improves table tool reading accuracy and reliability.Avoid bubble interference effect
Luminous intensity that photosensitive receiving tube receives and the induced current of photosensitive receiving tube is reduced, cause sensor code error, lead
Cause error in reading.
Specific embodiment
Technical solution of the present invention is detailed further below, but protection scope of the present invention is not limited to following institute
It states.
Anti- bubble photoelectric direct reading remote transmission water meter, including vibrating motor, direct-reading processor and camera, camera are set to table
Above disk, camera is used to shoot the reading image of pointer on water meter dial plate, is provided with anti-bubole analysis mould in direct-reading processor
Block, anti-bubole analysis module is used to extract the characteristic information in reading image, and judges whether there is gas according to this feature information
Bubble, when being judged as there is no bubble, the numerical value shown using moment reading image is water meter reading numerical value；When being judged as that there are gas
When bubble, direct-reading processor issues driving signal triggering vibrating motor running, and captures clearly not during vibrating motor running
There are the reading images of bubble, and the numerical value which shows is obtained the moment water meter reading numerical value by vibration compensation.
The determination of vibration compensation: starting vibrating motor under perfect condition (bubble is not present), under a certain vibration frequency,
The water meter reading numerical value measured when by vibration is compared with practical water meter reading numerical value, and the error in reading obtained under the vibration frequency is closed
System, obtains the design parameter of vibration compensation with this error in reading relationship.
The above is only a preferred embodiment of the present invention, it should be understood that the present invention is not limited to described herein
