Description

A kind of no accumulated error remote energy-saving collection is copied water meter

Technical field

The utility model relates to a kind of water meter, and especially a kind of no accumulated error remote energy-saving collection that can solve the floating voltage influence of critical localisation between the potentiometer end points is copied water meter.

Background technology

Still there are many local meter reading methods of registering one's residence that adopt in China at present, brings a lot of troubles for user and meter reading personnel, even the public security problem that causes.In order effectively to solve many drawbacks that the counting cost by gas meter of registering one's residence exists, to raise the efficiency, outdoor metering is very important, and long-range water meter arises at the historic moment well.

The exploitation of long-range water meter must reach accurate measurement, antijamming capability is strong, stability and good endurance, use safety, basic fundamental performance requirement such as antitheft, present all kinds of remote transmitting water meter has dropped into actual use, but all exist some such as stability, precision, serviceable life etc. such-and-such drawback, the related water meter of the utility model with compare at the remote transmitting water meter of usefulness at present, at aspect of performance remarkable advantages is arranged, it solved all at present the long-range water meter of usefulness occur such as lasting electricity consumption, the backflow error, the performance change that the impurity deposition causes, check meter number and problems such as the water meter registration is inconsistent have also solved the problem of the floating voltage influence of critical localisation between all potentiometer end points that run into based on the long-range water meter of potentiometer carbon film plate.

The utility model content

The technical problems to be solved in the utility model is: propose a kind of no accumulated error remote energy-saving collection and copy water meter, realize remote meter reading and digitizing toll administration, performance aspect energy-conservation and social security simultaneously.

The technical scheme that the utility model adopts is: a kind of no accumulated error remote energy-saving collection is copied water meter, comprises the water meter body, described water meter body, potentiometer of coaxial connection respectively in ten, the hundred third gear rotating shafts; Have outer ring carbon film plate and inner ring carbon film plate on the described potentiometer; The circle of described outer ring carbon film plate for not sealing; Described potentiometer has long and short two swivel arms; Long swivel arm contacts with the outer ring carbon film plate, and short swivel arm contacts with the inner ring carbon film plate; Described inner ring carbon film plate is arranged on the opening part of outer ring carbon film plate.

For the ease of the conversion of the real data of checking meter, two swivel arms of carbon film plate described in the utility model are drawn by extension line, respectively as signal wire and control line.

Water meter body surface described in the utility model is done encapsulation process.

The utility model drives the potentiometer rotation based on the water meter of one group of potentiometer carbon film plate repacking by former physical construction, and its water consumption is corresponding with one group of centre tapped position of potentiometer.When checking meter, in the current potential mode center tap present position is read, and be converted to the user water consumption information consistent with the water meter registration by processing of circuit, and carry out long-range unified management.

The beneficial effects of the utility model are: realize the remote meter reading operation, precision height (less than 0.5 ton), no accumulated error; Need not power at ordinary times, energy-conservation; Water meter registration and the long-range institute information of copying are in full accord; Long-life design (common water meter is consistent with now using) has good market outlook.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the circuit diagram of potentiometer lead-in wire of the present utility model;

Fig. 2 is A/D translation data and the corresponding synoptic diagram in carbon film plate position;

Fig. 3 is the potentiometer structural representation;

Among the figure: 1, outer ring carbon film plate; 2, inner ring carbon film plate; 3, long swivel arm; 4, lack swivel arm.

Embodiment

With preferred embodiment the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

As shown in figures 1 and 3, a kind of no accumulated error remote energy-saving collection is copied water meter, comprises the water meter body, described water meter body, potentiometer of coaxial connection respectively in ten, the hundred third gear rotating shafts; Have outer ring carbon film plate 1 and inner ring carbon film plate 2 on the described potentiometer; The circle of described outer ring carbon film plate for not sealing; Described potentiometer has long and short two swivel arms; Long swivel arm 3 contacts with the outer ring carbon film plate, and short swivel arm 4 contacts with the inner ring carbon film plate; Described inner ring carbon film plate is arranged on the opening part of outer ring carbon film plate.

As shown in Figure 1, going between each respectively, line goes out, wherein D1-D3 is the moving point of potentiometer extension line (signal wire), corresponding with user's water consumption, C1-C3 is critical localisation signal extension line (control line) between the potentiometer two-end-point, whether be used for to differentiate potentiometer at critical localisation, if, the then treatment circuit processing of the line voltage signal of this moment can being made zero.

Water, electricity are isolated in measures such as water meter use O-ring seal, with adjustment equipment the water meter of reequiping are proofreaied and correct.

When checking meter, the external world will power to the water meter potentiometer, and the moving point of potentiometer extension line (signal wire) current potential is carried out A/D successively change, be a group octet binary number by what obtain after the A/D conversion, in when communication, transmission also be eight-digit binary number, but this number only represents the position of potentiometer (sensor) slide head, for this numerical value can be united with the reading of water meter, must carry out the data Fuzzy Processing by computing machine.

Data Fuzzy Processing principle:

Because the water meter counting adopts decimal system counting, so at first a circumference is divided into ten five equilibriums, potentiometer is adjusted to reference position (water meter mechanical indicator position is 0), measure the A/D conversion value in the position of 0,0.2,0.5,0.8,1,1.2,1.5,1.8,2,2.2,2.5,2.8,3,3.2,3.5,3.8,4,4.2,4.5,4.8,5,5.2,5.5,5.8,6,6.2,6.5,6.8,7,7.2,7.5,7.8,8,8.2,8.5,8.8,9,9.2,9.5,9.8 correspondences respectively, and note, as shown in Figure 2.(annotate: owing to adopt Fuzzy Processing, the precision assurance of position is not upward had too high requirement.

(1) data of individual position are handled

It is 10 tons that individual position potentiometer turns around, owing to there is not accumulated error, thus can carry out value by numerical range, as table 1:
