Description
The utility model belongs to the flow measurement technology field, specifically a kind of non-transformer Weight and disk type water meter.
At present, generally adopt the mechanical type water meter to be realized to the metering of discharge.Its ultimate principle is to rely on flow dynamic to drive the wheel rotation of pipeline middle period, by impeller rotating shaft to the commutating tooth wheels engaged transmission of ratio of gear design in accordance with regulations between water meter counting needle pivot, make each figure place pointer rotation on the water meter, and according to the number of division of indicator of water gauge indication water meter index dial, by manual read's water draw rate data.This water meter is in the middle of using, and abominable because of its operate outside environment, the absorption of table inner suspension thing and impurity very easily causes water meter index dial glass fuzzy; Rely on artificial meter reading in addition, check meter, have error even mistake inevitably, these factors all are to produce reading to be forbidden, and even the reason place of the unreal disadvantage of charging.In addition, owing to use the mechanical type water meter, also can not rely on the modern management that manually realizes water flow measurement, charge overall process fully.
The purpose of this utility model then is the problem at above-mentioned existence, and a kind of power supply that need not to provide has been provided, and can realize the non-transformer Weight and disk type water meter of automatic accurate counting to discharge.
The utility model technical solution:
A kind of non-transformer Weight and disk type water meter, comprise impeller, main frame tool gear train (commutating tooth wheels), it is characterized in that all installing a pair of Infrared and send pipe and Infrared receiving tube on the vertical direction of each numerical digit of code-disc, 5,6 pin that wherein 01, the 02 2 pair of Infrared sends, the receiving tube output terminal is received the input string line output shift register U174LS165 that walks abreast respectively (are P
6, P
7), 11,12,13,14,3,4,5,6 pin that 03,04,05,06,07,08,09, the 010 8 pair of Infrared sends, the receiving tube output terminal is received parallel input string line output shift register U274LS165 respectively (are P
0-P
7), serial output terminal 9 pin of U1 link to each other with serial input terminal 10 pin of U2, and 2 pin of U1,16 pin are in parallel with 2 pin, 16 pin of U2 respectively, and 1 pin of U1 is in parallel with 1 pin of U2.
The utility model has following advantage compared to existing technology:
1. adopt mechanical water meter to combine, rely on mechanical transmission mechanism to drive photoelectric code disk, realize counting with the modern optical power technology.
2. The data opto-electronic conversion mode.It is made up of three parts, i.e. light source transmission, code-disc, light source receive.Wherein light source transmission, light source receive and adopt infrared transmission, infrared reception to pipe, to increase reliability.
3. coding is realized by code-wheel.Be to guarantee accuracy of reading, code-disc adopts continuously reliable gapless coding techniques to guarantee that opto-electronic conversion do not have frame hopping and occur.
4. the accurate location of photoelectric commutator and code-disc, can guarantee by mechanical positioning, add and adopt the mode of continuous programming code to detect data, the accuracy of this Weight and disk type water meter is identical with mechanical water meter even higher (rotates as long as the impeller of water meter drives code-disc, opto-electronic conversion is when work, only there is systematic error in water meter, owing to adopt coding techniques, its error can be reduced to minimum).
5. the reading of code-disc coding adopts the mode of parallel input string line output.Therefore the figure place that can guarantee to encode on the code-disc in the water meter is corresponding with the figure place of reading in the mechanical water meter.The figure place of increase and decrease mechanical water meter reading only needs the figure place of encoding on the corresponding increase and decrease code-disc.When code-disc reaches a location number, the figure place that increases code-disc again will make the diameter of code-disc excessive.For addressing this problem, the code-disc of plural same figure place can be together in series, each figure place of meter reading is distributed on these code-discs successively in an orderly manner.When reading of data, can only be realized that thus these five circuits are respectively ground wire, power lead, clock line, data line and control line by 5 working lines.
6. when the water-meter reading data, adopt the contactless optical power conversion technology, utilize software engineering to guarantee that reading of data is accurate.
7. code-disc is coded under the control of meter reading instrument, behind the IC circuit decoding, serial output data, and on display tube video data simultaneously.
8. water meter does not need to provide power supply, can realize automatic accurate counting.When needing the data of water-meter reading, pass through water-proof cable, be communicated with meter reading instrument (specialized designs), input service power supply (low pressure 3-6V), this moment is by serial communication line (2) and control line (1), gather flow and relevant data, and can on display tube, show relevant data simultaneously as required.
9. relevant datas (tentatively being decided to be 16) such as table number, personal code work are set in the water meter, make the user corresponding, make it with the PC communication time, once to import total data with its discharge counting.
10. the water meter of the utility model technology part can be through converting on the existing machinery water meter.Owing to adopt the contactless optical power conversion technology, just can not influence the reading of the mechanical rotation of water meter, and guarantee the accuracy that data of water meter reads.
