Description
Technical field
The utility model relates to a kind of anti-strong magneto-optic photoelectric direct reading teletransmission IC-card 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.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of anti-strong magneto-optic photoelectric direct reading teletransmission IC-card water meter, this water-meter outdoors has anti-strong magnetic lid, effectively can reduce the strong magnetic interference of Water meter core assembly, watch core is measured more accurate; Be provided with antifreeze assembly, adopt and produce through physical blowing the large air sacculus that countless separated foams forms by Low Density Polyethylene.Take full advantage of the performances such as the excellent water proof protection against the tide of this air sacculus, flexibility and resiliency, after current enter cavity, water volumetric expansion when glaciation, extrude antifreeze assembly, by compressing after air sacculus pressurized, offset the volume containing and expand when water build-ups ice thus, avoid the explosion of water meter.
The purpose of this utility model is achieved through the following technical solutions: anti-strong magneto-optic photoelectric direct reading teletransmission IC-card water meter, it comprises table body, water inlet and water delivering orifice, described table body comprises character wheel table, pointer gauge, IC-card induction zone, IC-card remaining sum viewing area and table cover, described IC-card induction zone and IC-card remaining sum viewing area are arranged on water outlet end, character wheel table, pointer gauge are arranged on inlet end, and described table cover is anti-strong magnetic lid; This water meter also comprises photoelectric direct-reading apparatus and antifreeze assembly, described photoelectric direct-reading apparatus comprises communication device, single-chip microcomputer, at least one luminotron and at least one receiving tube, the both sides being arranged on character wheel divided equally respectively by described luminotron and receiving tube along same circumference, antifreeze assembly is foaming EPE pearl wool, is arranged between watch core and table base.
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.
