Abstract
The utility model discloses an easily read formula photoelectric direct reading teletransmission valve accuse water gauge, its characterized in that: it includes watchcase (1), is provided with table lid (2), character wheel table (4), pointer gauge (5) and adjustment button (3) on watchcase (1), table lid (2) for convex lens formula table approximately, this water gauge still includes photoelectric direct -reading device and frostproofing subassembly, photoelectric direct -reading device include communication device, singlechip, at least one luminotron and at least one receiver tube, luminotron and receiver tube equally divide the setting in the both sides of character wheel along same circumference respectively, the subassembly that prevents frostbite is cotton for foaming EPE pearl, set up the watch core with show between the base. This water gauge uses the original glass of convex lens replacement table lid for the reading is easier, be provided with frostproofing subassembly, water is freezing volume expansion when build -uping ice, and bursting of water gauge through compress, offset expanded volume when having held water and build -uping ice behind the air sacculus pressurized from this, is avoided to the extrusion subassembly that prevents frostbite.
Description
Technical field
The utility model relates to a kind of readability formula photo-electronic directly reading teletransmission valve control 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, provides a kind of readability formula photo-electronic directly reading teletransmission valve control water meter, and this water meter uses convex lens to replace original glass table cover, makes reading easier; 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: readability formula photo-electronic directly reading teletransmission valve control water meter, and it comprises watchcase, watchcase is provided with table cover, character wheel table, pointer gauge and adjustment button; Described table cover is lenticular mode table cover; 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.
The material of described antifreeze assembly is foaming EPE pearl wool.
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 readability formula photo-electronic directly reading teletransmission valve control water meter, and this water meter uses convex lens to replace original glass table cover, makes reading easier; 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.
