Description
Technical field
The utility model relates to a kind of cleaning type photoelectric direct reading remote transmission water meter.
Background technology
Teletransmission is checked meter, the key problem that first will solve be how water meter is measured, the mechanical information that shows is converted to the electronic information that computing machine can process, i.e. data genaration.Namely traditional mechanical water meter installs magnet on certain gear, and correspondence position installs magnetic-sensitive elements, such as Hall element or tongue tube.Magnet is with pinion rotation, and when entering the induction zone of magnetic-sensitive elements, tongue tube adhesive exports pulse, then by counter circuit, pulse is converted into the flow of water.It is simple that mechanical water meter has structure, the advantage of easy realization, but principle of work itself determines mechanical water meter has fatal weakness, i.e. the counting loss not even enumeration problem that brings of strong magnetic interference, secondary measurement, cumulative errors cause the problem of the low and error in reading of degree of accuracy.
But having following problem when the mode adopting photo-electronic directly reading: light is can reflect by light during different medium, and diffuse reflection can occur by during medium that refractive index is large, such as optical fiber is exactly this principle; May reflect during by filling alveolate solution, reflecting, a series of phenomenon such as scattering such as light-emitting toy rod etc.Refraction effect directly causes optical path direction deviation, and light dies down, so that Signal transmissions is unstable, the status requirement of sensitizing tube and photosensitive tube high (slightly displacement will not receive signal) for photoelectricity water meter.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of cleaning type photoelectric direct reading remote transmission water meter is provided, this water-meter outdoors has clean layer, can clean character wheel table cover while unlatching table cover, cleaning of effective guarantee character wheel table cover, this water meter compact, easy to carry, take up room little.
The purpose of this utility model is achieved through the following technical solutions: cleaning type photoelectric direct reading remote transmission water meter, it comprises water inlet, water delivering orifice, table body and data line, described table body comprises table cover and character wheel table, table cover is connected with around the strip winding showing body by pivot, described table cover internal layer is provided with clean layer, table cover is covered by screw thread and table body, and described clean layer contacts with character wheel table cover when covering; This water meter also comprises photoelectric direct-reading apparatus, and described photoelectric direct-reading apparatus comprises communication device, single-chip microcomputer, at least one luminotron and at least one receiving tube, and the both sides being arranged on character wheel divided equally respectively by described luminotron and receiving tube along same circumference.
Described table body adopts PP-R nonmetallic materials to be made, and is provided with consubstantiality injection moulding silk.
Described single-chip microcomputer adopts ATmega48PA.
Described communication device is provided with RS485 or M-BUS communication interface.
The beneficial effects of the utility model are: the utility model provides a kind of cleaning type photoelectric direct reading remote transmission water meter, this water-meter outdoors has clean layer, can clean character wheel table cover while unlatching table cover, cleaning of effective guarantee character wheel table cover, this water meter compact, easy to carry, take up room little, use PP-R nonmetallic materials to make table body, make water meter corrosion-resistant, reduce cost of manufacture.
