Detailed description of the invention
Below with embodiment, this utility model is more fully illustrated.This utility model can be presented as multiple not
Same form, is not construed as the exemplary embodiment being confined to describe here.
For ease of explanation, here can use such as " on ", the space relative terms such as D score " left " " right ", be used for
Shown in bright figure a element or feature are relative to another element or the relation of feature.It should be understood that except in figure
Outside the orientation illustrated, spatial terminology is intended to include device different azimuth in use or operation.Such as, if in figure
Device is squeezed, be stated as being positioned at the element of other elements or feature D score will be located into other elements or feature " on ".Cause
This, exemplary term D score can comprise upper and lower both orientation.Device can otherwise position (90-degree rotation or be positioned at
Other orientation), relatively illustrate used herein of space correspondingly to explain.
As depicted in figs. 1 and 2, the IC-card water meter in the present embodiment, including mechanical water meter, digital display unit (in figure not
Illustrate) and IC-card read-write cell (not shown)；Digital display unit (not shown) and IC-card read-write cell are (in figure not
Illustrate) it is prior art, repeat no more here.Wherein, usual dial plate 2 has 7 pointers 3；Pointer 3 in figure has carried out letter
Change, only depict one.
In embodiment, the metering of digital display unit uses and counts the instruction tooth on the runner 4 of mechanical water meter in fact
Existing.Specifically, reflecting plate 5 is set below the runner 4 of the dial plate 2 of mechanical water meter.Reflecting plate 5 can be glass lens, aluminium foil,
The reflectorized materials such as corrosion resistant plate are made, it is also possible to form light reflecting membrane by electroplating or be coated in surface, dial plate 2 relevant position
As reflecting plate 5.
It is provided with laser transmitter device and receiving device, laser transmitter device and receiving device respectively at digital display unit
The fiber interface hole 601 being penetrated optical transmission component 6 by optical fiber is connected with optical transmission component 6.
Laser is produced by laser transmitter device, is entered by plastic optical fiber and sets on bell glass above the dial plate 2 of mechanical water meter
The optical transmission component 6 put, in runner 4 rotary course, instruction tooth can pass optical transmission component 6 light channel, can block or
Shut the light 6, light pulse can be produced at receiving terminal.By the counting to light pulse, the rotating cycle of runner 4 can be obtained, right
Ground is answered to obtain the flow of water meter.It is of course also possible to replace laser with other visible rays；Owing to laser direction is good, the arteries and veins obtained
Rushing waveform can get well, without shaping, processing circuit can be simple, uses laser to carry out measuring the system of advantageously reducing as signal source
Error in dipping.Correspondingly, light emitting devices and receiving device are laser diode and laser pick-off device.
Optical transmission component 6 is arranged on outside water meter, little on the impact of water meter internal structure；Conveniently mechanical water meter is changed
Make.Meanwhile, it also avoid the impact that water meter is sealed.
Glass optical fiber can also be used between laser diode and laser pick-off device and optical transmission component 6；Due to plastic light
Fine diameter is relatively thick, good toughness, it is not easy to disconnected；And the angle of incidence of light is required relatively low, use plastic optical fiber can reduce light
The requirement of conducting parts 6 machining accuracy.
As it is shown on figure 3, optical transmission component 6 includes pedestal 601 and buckle 604；Light string holes is set on pedestal 601；Light string holes
Including fiber interface hole 601 and fiber-optic transfer hole 603；Fiber interface hole 601 is for being connected with digital display unit.Fiber-optic transfer
Hole 603 is for fixing the generation direction of optical fiber and receiving direction.Fiber-optic transfer hole 603 is located normal to the same plane of dial plate
In.
The distance dependent between distance and angle of inclination and bottom and reflecting plate 5 bottom fiber-optic transfer hole 603, by meter
Calculation can obtain, and this calculating belongs to prior art, here repeats no more.Angle of inclination is arranged on and dial plate 2 end face 80 to 85
Between degree, reflecting effect is preferable.
It is connected by cushion chamber 602 between fiber interface hole 601 with fiber-optic transfer hole 603.Cushion chamber 602 passes through for optical fiber
The space of bending, it is to avoid optical fiber in use fractures；The shape of cushion chamber can be cuboid or square, spheroid or other
Optical fiber will not be made to produce the radius shape less than 3cm radian.Cuboid or square is used to be easy to mould processing.
Optical transmission component 6 makes the light entered from optic fibre hole, and the direction contrary with entering light from opposite side optic fibre hole is defeated
Go out；Owing on dial plate, pointer is more, be so conducive to saving the layout of optical transmission component 6.
The pedestal 601 of optical transmission component 6 and buckle 604 split are arranged；So convenient processing, beneficially the installation of optical fiber and
Adjust.Pedestal 601 and buckle 604 can connect by screw is fixing, it is also possible to connect by the way of bonding or clamping.
In order to obtain wider impulse waveform, when being embodied as, also the shape of runner 4 should be replaced by hexagonal by profile of tooth
Star.Pinwheel impeller shape is more preferable as in Figure 1 and Figure 2.
Above-mentioned example be only intended to illustrate this utility model, in addition, the most multiple different embodiment, and these
Embodiment be all those skilled in the art after comprehension this utility model thought it is also envisioned that therefore, no longer one string at this
Lift.
