Description
Technical field the utility model relates to measurement mechanism, especially relates to the linear direct-reading code-disc device of reading of data in the long-distance meter-reading system.
What the technical background code-disc used is mechanical reading, is widely used in the instrument such as watt-hour meter, water meter and gas meter, flow meter.For satisfying the long-range needs of copying number, existing remote installed meter is divided into: dry-reed, Hall element formula, photoelectric coding type etc.Before dual mode be real-time accumulated pulsed quantity, have multiple-pulse or lose the problem of pulse, and need energising in real time, exist reading inaccurate, the shortcoming that power consumption is big; The major defect that photoelectric coding type then exists critical conditions to misread, when critical conditions (be code-disc show numerical value between two integers), can't accurate reading, so coding type direct-reading code-disc can only be called accurate direct-reading or pseudo-direct-reading.
The summary of the invention the purpose of this utility model is the deficiency that exists at above-mentioned code-disc, and a kind of novel code-disc is provided.The numerical value of its output shows that with the code-disc window numerical value is linear corresponding, and only just switches on when reading, and the numerical value of reading shows that with code-disc numerical value is consistent, is a kind of real direct-reading code-disc.
A kind of linear direct-reading code-disc device that is used for long-distance meter-reading system of the utility model, comprise shell, be used for showing the measured medium consumption character wheel, be positioned at wiring board that the character wheel side is used to read character wheel location status band detection probe group, be used for changing and drive the gear wheel that character wheel rotates and carry out signal Processing and transmit signals to the signal-processing board of remote processor according to the measured medium consumption; Described detection probe group is the probe group that has linear output character, is used for range observation, and it is the helicoid of center line that described character wheel axial end is provided with the character wheel axial line, and the illuminating part of detection probe group is aimed at above-mentioned helicoid.The linear direct-reading code-disc Design of device principle that the utility model is used for long-distance meter-reading system is: the axial vane surface of character wheel is made up of helicoid, so detection probe group of fixing in its side and the distance between the helicoid are linear change with the rotation of character wheel, according to the characteristic of linearity test probe, it is linear that its output signal also is.And each printing numerical value of character wheel is always corresponding to the ad-hoc location of helicoid, thereby the output of detection probe group shows that with character wheel numerical value is corresponding one by one, so no matter character wheel is parked in any position, and the numerical value of reading can both show that numerical value is consistent with character wheel.
The utility model is used for the linear direct-reading code-disc device design science of long-distance meter-reading system, and is simple and reasonable for structure, and the value of reading is accurate, and the numerical value of copy reading whenever is in full accord with the numerical value of code-disc window demonstration, is a kind of passive direct-reading code-disc truly.

The concrete structure of the direct-reading code-disc of the linear reading numerical values of embodiment the utility model is provided in conjunction with the following examples in detail by top accompanying drawing.
Can be clear that from Fig. 1,2, a kind of linear direct-reading code-disc device that is used for long-distance meter-reading system comprises shell 1, is used for showing that the character wheel 2 of measured medium consumption, the side that is positioned at character wheel 2 are used to read the wiring board 3 of character wheel 2 location status band detection probe groups 31, are used for changing according to the measured medium consumption and drive the gear wheel 4 that character wheel 2 rotates and carry out signal Processing and transmit signals to the signal-processing board 5 and the output shaft 6 of remote processor; Described detection probe group 31 is the probe group that has linear output character, is used for range observation, and it is the helicoid 21 of center line that described character wheel 2 axial ends are provided with character wheel 2 axial lines, and the illuminating part of detection probe group 31 is aimed at above-mentioned helicoid 21.The linear direct-reading code-disc Design of device principle that the utility model is used for long-distance meter-reading system is: the axial vane surface of character wheel 2 is made up of helicoid 21, so detection probe group 31 of fixing in its side and the distance between the helicoid 21 are linear change with the rotation of character wheel 2, according to the characteristic of linearity test probe, it is linear that its output signal also is.And each printing numerical value of character wheel 2 is always corresponding to the ad-hoc location of helicoid 21, thereby the output of detection probe group 31 shows that with character wheel 2 numerical value are corresponding one by one, so no matter character wheel 2 is parked in any position, and the numerical value of reading can both be consistent with character wheel 2 demonstration numerical value.
By Fig. 3 and Fig. 4 the principle of the technical solution of the utility model detection probe group 31 linear reading numerical values is further detailed; Originally the mechanical code-disc mechanism course of work of linear direct-reading code-disc device that is used for long-distance meter-reading system is identical with existing code-disc reading device, and selecting the photocoupler group for use with the detection probe group 31 that above-mentionedly has linear output character, is used for range observation is example: (0.8mm～8.0mm) increases progressively and successively decreases the relative output current Δ Ic of detection probe group 31 with d; Rotation along with character wheel 2, detection probe group 31 on the wiring board 3 and helicoid 21 be the relation of linear increment apart from d, so under the condition that guarantees 0.8mm＜d＜8.0mm, the relative output current Δ Ic of detection probe group 31 and the position of character wheel 2 are linear, handle by 5 pairs of signals of signal-processing board, can obtain and the corresponding linear numerical in character wheel 2 positions, thereby realize direct-reading.Here the meaning of " direct-reading " be meant character wheel 2 no matter show numerical value can both obtain in any position (comprising decimal) in value corresponding.By adopting technique scheme, just can realize no matter which kind of position character wheel 2 forwards to, the relative output current Δ Ic of detection probe group 31 can both obtain corresponding with it unique numerical value, and is treated, the numerical value of output and the demonstration numerical value of character wheel 2 are in full accord, thereby realize the direct-reading function.
As can be seen from Figure 1, be exactly that described helicoid 21 adopts simple helix face 211 as the simplest way, what detection probe group 31 was provided with on the described wiring board 3 is a detection probe 311.
As can be seen, under the situation that adopts simple helix face 211, there are sudden change in starting point and terminal point from Fig. 4 to Fig. 6, and there is hidden danger in reading at this moment.Can solve the above problems, adopt at least two segmentation helicoids 212 and 213 at described helicoid 21, adjacent segmentation helicoid 212 is opposite with 213 rotation direction, each section segmentation helicoid 212 or 213 each corresponding detection probe 312.The axle side of character wheel 2 is adopted and is no less than two segmentation helicoids 212 and 213 that join each other, contain on the wiring board 3 simultaneously and be no less than two photocouplers 312, so just there is not the problem of sudden change, obtains correct reading by output and sequencing processing to different detection probe 312.
For another expansion embodiment of the present utility model, described helicoid 21 is provided with continuous ladder plane 214 from top to bottom, and its principle of work and above-mentioned basic identical repeats no more here.
All belong to mature technology, just narration separately here for the electronic processing technology of output current Δ Ic and the signal Processing on the signal-processing board 5 and transmission technology.
