Abstract
The utility model discloses a prevent strong magnetism photoelectric direct reading teletransmission water gauge, it includes water inlet (2), delivery port (3), shows the body (1) and data transmission line (4), the table body (1) including table lid (6) and character wheel table (5), table lid (6) through screw thread and table personally experience sth. Part of the body (1) cover and close, table lid (6) for preventing strong magnetism lid, this water gauge still includes photoelectric direct -reading device, 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 both sides of setting at the character wheel along same circumference respectively. This water gauge is provided with prevents strong magnetism lid, can effectively reduce the strong magnetic disturbance of water gauge watch core subassembly for the watch core measurement is more accurate. This water gauge small in size, convenient to carry, occupation space is little, use the PP -R non -metallic material preparation table body for the water gauge is corrosion -resistant, reduces the cost of manufacture.
Description
Technical field
This utility model relates to a kind of anti-strong magnetic photoelectric direct reading remote transmission water meter.
Background technology
Teletransmission is checked meter, the key problem first having to solve be how water meter is measured, the mechanical information that shows is converted to the electronic information that computer 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, when entering the induction zone of magnetic-sensitive elements, and tongue tube adhesive output pulse, then pass through counter circuit and pulse is converted into the flow of water. Mechanical water meter has simple in construction, the advantage easily realized, but operation principle itself determines mechanical water meter and has fatal weakness, the counting loss not even enumeration problem that namely strong magnetic disturbance brings, secondary measurement, cumulative errors cause degree of accuracy low and the problem of error in reading.
But having problems with when adopting the mode of photo-electronic directly reading: light light when by different medium can reflect, and during by medium that refractive index is big, diffuse-reflectance can occur, for instance optical fiber is exactly this principle; It may happen that a series of phenomenons such as light-emitting toy rods etc. such as reflection, refraction, scatterings during by filling alveolate solution. Refraction effect directly results in optical path direction deviation, and light dies down, so that signal transmission instability, 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 in that to overcome the deficiencies in the prior art, it is provided that a kind of anti-strong magnetic photoelectric direct reading remote transmission water meter, and this water-meter outdoors has anti-strong magnetic lid, it is possible to effectively reduce the strong magnetic disturbance of Water meter core assembly so that watch core metering is more accurate. This water meter compact, easy to carry, take up room little.
The purpose of this utility model is achieved through the following technical solutions: anti-strong magnetic photoelectric direct reading remote transmission water meter, it includes water inlet, outlet, table body and data line, described table body includes table cover and character wheel table, and table cover is covered by screw thread and table body, and described table cover is anti-strong magnetic lid;This water meter also includes photoelectric direct-reading apparatus, and described photoelectric direct-reading apparatus includes communication device, single-chip microcomputer, at least one luminous tube and at least one reception pipe, described luminous tube and reception pipe and divides equally the both sides being arranged on character wheel respectively along same circumference.
