Embodiment:
As shown in Figure 1, this TM card intellectual water meter adopts control, metering integrated design, and the TM card is used in the patented product DS1991TM card of U.S. DALLAS company.Its outside is a shell 1, has table to cover 4 on the shell, and a side of shell is established TM card deck 2.In the shell, a side is installed little power consumption electric control valve 3, and the centre is closed assembly integrating mechanism 5 layer by layer from top to bottom, control circuit board 9 and metering mechanism 13, and opposite side is established battery case 7.The inlet channel 16 of water meter connects little power consumption electric control valve 3, and water outlet 12 meets metering mechanism 13.Between inner each ingredient of water meter two kinds of mechanical annexation and electrical connections are arranged, mechanical connecting part has: the water outlet 15 of little power consumption electric control valve 3 links to each other with the inlet channel 14 of metering mechanism 13, and the coupling of magnet steel 8 on the other side realizes the transmission of flow information of water in metering mechanism 13 and integrating mechanism 5 magnet steel 10 by 11 tops of impeller in the metering mechanism and the integrating mechanism.Electrical connections is as shown in Figure 2: the interface of single chip machine controlling circuit plate 9 connects TM deck 2, little power consumption electric control valve 3, the in-house sensor 6 of integrating and battery case 7 electrode realization information respectively to be transmitted and handles.
This water meter is in order to realize integrated design, adopted volume little, flow is big, leak free little power consumption electric control valve, its structure as shown in Figure 3: electrically-controlled valve is by valve body 17, form into and out of water channel 16,15, spool 25, three magnet steel 20,22,24, disk 23, micromotor 19 and the spline tips 21.The end of spool 25 embeds a circular magnet steel 24, with nonmagnetic substance valve end is sealed, a disk 23 is installed over against the top of spool 25 in outer end at gland bonnet 18, and same radius embeds two circular magnet steel 22,24 that magnetic pole is opposite at a distance of the position at right angle on disk 23; And disc centre is fixed on the rotation axis of micromotor 19, the axle center of micromotor 19 will make magnet steel 20 centers on magnet steel 22, the 24 centrally aligned spools on the disk in the position on the disk 23, and such structure has just formed two pairs of touchless magnetic push rods.Round plate between two magnet steel 22,24 sets up sector notch separately, and the spline tip 21 that is fixed in valve body 17 tops can be stretched in the breach.Add the pulsewidth voltage that guarantees to rotate 90 degree when motor, the disk that drive is fixed on the motor shaft rotates, and stops the magnet steel of the magnet steel on this hour indicator on the spool when running into the spline tip, when its magnetic is identical, because the same sex effect of repelling each other, spool is subjected to its thrust close port, blocks current, as backward rotation disk again, make its another magnet steel aim at the spool magnet steel, because the magnet steel on this disk and the magnet steel opposite sex on the disk, so also different in nature with the magnet steel on the spool.There is a natural attraction between the sexes and form, and the spool magnet steel is subjected to suction to open valve port, conducting current.Be the rotation of disk,, become moving back and forth of spool by the effect of magnetic push rod.
Secondly, this water meter has been done particular design to the shape chamber of metering mechanism 13, as shown in Figure 1, it is designed to straight chamber form, and shape chamber diameter is φ 64+0.2mm, is 37mm deeply, and the consistance of its geometric shape is better, manufactures easily, thereby improves the metering accuracy.
The control circuit board of this water meter has adopted the SMT surface mounting technology, so size is less.Its circuit is conventional circuit, its circuit block diagram as shown in Figure 4: it is to be core with CPU PIC 16/57, and CPU circuit respectively connects TM card read/write circuit, water yield information-processing circuit, storer, valve-driving circuit and low-voltage identification circuit.The output terminal of valve-driving circuit connects the electrode of little power consumption electric control valve, low-voltage identification circuit connection battery case, and water yield information-processing circuit connects sensor.
The course of work of this TM card intellectual water meter:
1. after the user holds TM and snaps into water supply administrative authority and purchase water, the TM card is contacted with the access hole of water meter, water meter can be to I.D., the water yield data of TM card, password is discerned and read in, after water meter correctly reads in, by microprocessor, water yield data are kept at Biao Nei and remove water yield data on the TM card.
2. in a single day have water yield data in the table, whether single chip circuit detects little power consumption electric control valve automatically and opens, if do not open, circuit will drive the micropower motorized valve and drive valve.
3. one ton of water of the in use every use of water meter, integrating mechanism sends out a water yield to single chip circuit and uses pulse, and single chip circuit will be shown the water yield data minus 1 in the internal storage automatically.Single chip machine controlling circuit will drive valve closing when water yield data are kept to 0, stop to supply water, and this moment, user Ying Chi imported water yield data with the TM card of water yield data to table, so that resume water supply.
4. this table adopts No. 5 powered battery of 4 joints, and when cell voltage was lower than a certain value, through the identification of low-voltage identification circuit, water meter was valve-closing, but the water yield data of depositing in showing do not lose, in case after changing new battery, the user can open water meter with the TM card.
