Description
Technical field
The utility model belongs to the fluidic counter accessory, especially belongs to photoelectric direct reading water meter counter.
Background technology
At present the counter on water meter, have three kinds of numerical value display modes, and 1, full pointer; 2, full word wheel; 3, pointer and character wheel mixed type.The heavy caliber table generally is loaded in deep table well, mostly is pointer, can judge reading by the angle of judgement pointer, more convenient in down-hole for the naked eyes reading, but full pointer because gear ratio is more, so sensitivity is generally bad.If, and character wheel is loaded in the table well because of distance, badly see clearly, thus multiplex in family expenses, reading closely.Still character wheel relatively more commonly used and the mixed type of pointer, usually in this case, more than 1 ton, adopt character wheel, the following pointer of use of radix point, tonnage indicates pointer generally to have three, be respectively x0.1 ton, x0.01 ton, x0.001 ton, also have one to be used for the round pointer whether the identification current flow.As shown in Figure 1, it is comprised of table cover 1, pointer 2, scale 3, counter block 4, lower plate 9, circuit board 10, central gear 11, supporting plate 12, fixed cover 13 etc.Along with the progressively expansion of tap water each household one table improvement project, the counting cost by gas meter workload constantly increases, the needs that traditional manual metering mode more and more can not adapt to development, and Automatic meter reading is vigorously advocated and is applied.Existing direct-reading gage adopts photoelectric reflection direct-reading technology: be that several sensors are installed on the cambered surface of each character wheel of water meter counter, the output of a character wheel all the sensors has formed the angle information coding of this character wheel, state by the judgement sensor is determined the position of character wheel, thereby can obtain the numeral on character wheel.And there is no corresponding direct-reading system for pointer, therefore the current mixed type direct-reading gage least unit that can read the water yield is ton, while using 24 hours monitoring water situations of direct-reading water meter, if zone, place 24 hourly consumptions are no more than 1 ton, direct-reading water meter just can't be monitored its water situation.
Summary of the invention
The utility model purpose is to overcome the shortcoming that above-mentioned direct-reading water meter exists, and a kind of energy direct-reading to 0.01 high-precision intelligent photoelectric direct reading water meter counter that ton water yield changes is provided.
The technical scheme that the utility model is used is a kind of high-precision intelligent photoelectric direct reading water meter counter, comprise table cover, pointer, scale, counter block, lower plate, circuit board, central gear, supporting plate, fixed cover, its main points are, it also has pointer direct-reading mechanism, pointer direct-reading mechanism comprises the circuit soft board that is fixed with photodiode, platen, the photoelectric reflection dish, the axle of pointer passes scale, the axle of the endoporus of needle pivot and photoelectric reflection dish joins, the other end of photoelectric reflection dish axle and original pointer gear axle join, below the photoelectric reflection dish, has platen, it below platen, is the circuit soft board that is fixed with photodiode, circuit soft board is fixed in counter block, circuit soft board is electrically connected to circuit board.
Principle of work of the present utility model, between existing pointer and pointer gear axle, to insert pointer direct-reading mechanism, by the photoelectric reflection dish, synchronize and rotate with pointer, photodiode obtains the position at photoelectric reflection dish place, thereby obtain the residing position of pointer, by photoelectric reflection direct-reading technology, read total indicator reading, there is no the pulse cumulative errors, avoided having caused because of external interference the situation of read untrue, with traditional pulse meter, compare, it can be reduced to reading error zero, non-transformer in table, only when checking meter, power up work, avoided because power supply is unreliable, unstable or error in dipping that fault causes and a large amount of maintenance works.
Each pointer is to there being a photoelectric reflection dish, and the first-class angle of circumference of corresponding circuit soft board evenly is fixed with five photodiodes.Such photoelectric reflection dish just can be distinguished ten different positions, and meets existing metric metering demand.
Three pointers of indicating respectively 0.1 ton, 0.01 ton, 0.001 ton are arranged, its below is fixed with respectively the photoelectric reflection dish, the corresponding first-class angle of circumference of circuit soft board in pointer below evenly is fixed with five photodiodes, and platen has light hole in the photodiode corresponding position.The pointer of 0.001 ton below also is furnished with the photoelectric reflection dish in theory, can read the reading of 0.001 ton of pointer, but when the pointer of x0.01 position makes zero, the pointer of x0.001 position also must make zero, when in fact likely the x0.01 position indicator pointer made zero, the pointer of x0.001 was sometimes between 9-0, sometimes be between 0-1, whether x0.01 has carry so need to judge with the pointer of x0.001 position, to guarantee the reading accurate rate of 0.01 ton of pointer.
Fixed cover 13 is copper sheathing.Can effectively thorough waterproof.
The utility model is simple in structure, there is no the pulse accumulation, does not have cumulative errors, and intelligent object does not participate in metering, can not affect measuring accuracy yet, and its operating accuracy is determined by table meter itself fully; Allow the kilowatt meter reading-out system intermittent work, require low to system performance; Low in energy consumption, adapt to the long-acting power supply of battery powered mode; Unique address, for the table meter is determined an identify label accurately; Copy reading data accuracy rate 100%.Can 24 hours monitoring waters of general application.
