Abstract
The invention discloses an anti-bubble photoelectric direct-reading remote water meter. An anti-bubble analyzing module is arranged in a direct-reading processor and used for extracting characteristic information in a number reading image and judging whether bubbles exist according to the characteristic information, and when it is judged that no bubble exists, a numerical value displayed in the number reading image at this moment is taken as a water meter reading value; when it is judged that bubbles exist, the direct-reading processor sends a drive signal to trigger a vibration motor to be operated, a clear bubble-free number reading image is caught during operation of the vibration motor, and a numerical value displayed by the number reading image is processed through vibration compensation to obtain a water meter reading value at this moment. According to the anti-bubble photoelectric direct-reading remote water meter, when it is recognized that the bubbles exist in the image, the vibration motor is automatically started to shift the positions of the bubbles through vibration, the clear bubble-free number reading image is caught in the vibration process, vibration compensation is performed on the read number, the number reading precision is improved, and the bubble interference resisting effect is obvious.
Description
Technical field
The present invention relates to a kind of photoelectric direct-reading water meter, particularly relate to a kind of anti-bubble photoelectric direct reading remote transmission water meter.
Background technology
Photoelectric direct-reading water meter is the outer rim printing specific markers of the character wheel of counter printing 0-9 position at common water meter, at its peripheral fixed light electric transducer and interlock circuit.During externally fed meter reading, judge that specific markers " has " and the state of "None" by photoelectric sensor.Photoelectric direct reading remote transmission water meter passes through character wheel founding mathematical models, calculate through combination, therefrom obtain uniquely correct solution, and then specifically mark according to mathematical law printing on the relevant position of character wheel 0-9, around it, according to mathematical law, fixed light electric transducer is installed again, so just a mathematical problem is realized by electronic circuit method.Consider the algorithm of various fault-tolerant, error correction simultaneously, just can draw uniquely correct solution---the unique data namely on character wheel.
The feature of photoelectric direct reading remote transmission water meter is: 1), directly read the counter encoder digital of table tool i.e. " window value ", without the need to arranging the parameter such as the table truth of a matter, table constant in table, without the need to storing data, there are not cumulative errors, really achieve " meter reading ", finish the history of accumulated pulse, conversion numerical value.Direct-reading gage tool electronic section is separated completely with the device such as counter in table tool, does not have Mechanical Contact, does not affect measuring accuracy.2), direct-reading remote installed meter directly transmits data, and non-pulse signal.It does not only affect by mechanical shock, also has high anti-interference to electromagnetic interference (EMI) simultaneously, thus can stablize under the environment for use of complexity, accurately, reliably realize metering.3), due to the collection of direct-reading remote installed meter is the position (and non-pulse) of mechanical counter character wheel, and when therefore showing tool generation reversing situation, meter reading data is still consistent with the reading once showing tool.
The direct-reading gage adopted at present in this way mainly contains photoelectricity correlation (transmission) formula and photo-electric reflection type two kinds, and main difference is the difference of physical construction and mathematical algorithm.Photoelectricity correlation (transmission) formula technology can only be applied to dry-type meter, and photo-electric reflection type technology not only can be applied to dry-type meter, and can be applied to liquid-seal water meter.Easily bubble is produced in wet-type meter fluid-tight box, especially on encoding strip or when there is bubble in coding groove, the light that light-emitting tube sends by time easily produce the phenomenons such as refraction, the light intensity being irradiated to photosensitive receiving tube is reduced, the induction current of photosensitive receiving tube is reduced, cause sensor code error, cause the error in reading because bubble interference produces; For bubble interference, current industry does not also have effective method, due to the restriction of bubble interference, makes the popularization of photoelectric direct reading wet type water meter there is very large bottleneck.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of auxiliary and software process by hardware, the obvious anti-bubble photoelectric direct reading remote transmission water meter of anti-bubble interference effect.
The object of the invention is to be achieved through the following technical solutions: anti-bubble photoelectric direct reading remote transmission water meter, involving vibrations motor, direct-reading processor and camera, camera is arranged at above dial plate, camera is for taking the reading image of pointer on water meter dial plate, anti-bubole analysis module is provided with in direct-reading processor, anti-bubole analysis module is for extracting the characteristic information in reading image, and judge whether to there is bubble according to this characteristic information, when being judged as there is not bubble, with the numerical value of this moment reading image display for water meter reading numerical value; When being judged as there is bubble, direct-reading processor sends drive singal and triggers vibrating motor running, and the reading image that there is not bubble is clearly caught during vibrating motor running, the numerical value that this reading image shows is obtained this moment water meter reading numerical value through vibration compensation.
The determination of vibration compensation: Vibration on Start-up motor under perfect condition (there is not bubble), under a certain vibration frequency, the water meter reading numerical value recorded during vibration and actual water meter reading numerical value are compared, obtain the reading error relation under this vibration frequency, obtain the design parameter of vibration compensation with this reading error relation.
The invention has the beneficial effects as follows: in image recognition to Vibration on Start-up motor automatic when having bubble to exist, to vibrate transfer bubble position, catch the reading image that there is not bubble clearly in the process, and vibration compensation is carried out to this reading, improve reading accuracy, anti-bubble interference effect is obvious, improves table tool reading accuracy and reliability.The light intensity avoiding bubble disturbing effect photosensitive receiving tube to receive and the induction current of photosensitive receiving tube is reduced, causes sensor code error, causes error in reading.
Embodiment
Technical scheme of the present invention is described in further detail, but protection scope of the present invention is not limited to the following stated below.
