Described non-contact IC card type U-shaped digital water gauge, it is characterized in that, its circular water meter scale panel 29 is the panels that are made of plastic material, engrave the great circle arc-shaped scale 9 of 10,15 and openings of circular scale of two sealings above it respectively, be respectively: one is that multiplying power is * 0.001 circular scale 15, the center of its index dial 15 is equipped with the tuning drive gear 14 of a correspondence, have 10 big lattice on the index dial 15, from 0 to 9, each big lattice is divided into 10 little lattice again, and each little lattice is represented 0.001m
3, water loss 0.001 * 100=0.1m is represented in 360 ° of pointer 14 every clockwise deflections
3One is that multiplying power is * 0.1 circular scale 10, and the center of its index dial 10 is equipped with the tuning drive gear 11 of a correspondence, has 10 big lattice on the small dial 10, from 0 to 9, and each big lattice is divided into 10 little lattice again, and each little lattice is represented 0.1m
3, water loss 0.1 * 100=10.0m is represented in 360 ° of pointer 11 every clockwise deflections
3One is that multiplying power is * 10 high range dish 9 circular arcs, be positioned at the outmost turns of circular water meter scale panel 29, the center of its water meter scale panel 29 is equipped with corresponding tuning drive gear 12, have 11 big lattice from 0,20,40,60,80,100,120,140,160,180,200 on the high range dish 9, each big lattice is divided into 10 middle lattice again, lattice contain little lattice in each, thus each big lattice to be divided into be 20 little lattice, each little lattice is represented 10m
3, on behalf of the surplus water on the current water meter, pointer 12 every inverse clock deflection one big lattice reduce by 20 * 10=200.0m
3
Among the present invention, on water meter scale panel 29, corresponding multiplying power is the center position of * 0.001 index dial 15, the pointer 14 of a multiplying power for * 0.001 index dial is installed, its corresponding multiplying power is the center position of * 0.1 index dial 10, the pointer 11 of a multiplying power for * 0.1 index dial is installed, its corresponding multiplying power is the center position of * 10 index dial 9, the pointer 12 of a multiplying power for * 10 index dials is installed, three pointers pass the center pit of the index dial of multiplying power separately on the water meter scale panel 29 simultaneously, respectively be installed in pcb board on pointer driving shaft 39 sockets of corresponding micro-step motor movement.
Internal thread on the circular water meter cover 8 joins with the external thread of the hollow cylinder of U-shaped water meter pedestal 1, all with digital water meter pointer movement, low-power scm 21, water yield sampling unit 25, water meter scale panel 29, lithium Asia electric battery 22 and and battery management module 40 all be sealed in the hollow cylinder of U-shaped water meter pedestal 1 central top.
Electric theory diagram of the present invention such as figure ten, low-power scm 21 obtains water flow signal by the water yield sampling unit 25 in the water meter pedestal 1, through signal condition change-over circuit 30 water flow signal is converted to electric impulse signal, pass to low-power scm 21 again, be converted into the required angular displacement of each rotation axis deflection of micro-step motor movement on the digital water meter pointer movement as calculated, indicate on the index dial of correspondence and use aqueous condition in real time thereby drive each pointer, at this moment the scale of indication is the remaining water consumption of user.The user is during water, the scale position on the index dial that three pointers 11,12,14 of water meter rest on respectively separately, and low-power scm 21 is in dormant state.
Different with the surplus water indicating mode with the mode of swiping the card of known IC-card formula water meter is, the present invention has removed mechanical digital character wheel group or the lcd screen in the conventional water meter, adopted the mode of digital water meter pointer movement to show the remaining water yield of purchasing, the purchasing the water yield and can show by digital pointer of IC-card that the user holds by the water yield of contactless IC card with its purchase, 26 and the LED light 13 in district of swiping the card that are designated wavy contactless IC card are arranged on the circular water meter scale panel 29, the user holds wavy the swipe the card district 26 of IC-card near water meter scale panel 29, can realize contactless swiping the card, swipe the card after the success, LED light 13 flickers once, the water yield that prestores on the IC-card promptly is transformed into the water yield that multiplying power is indicated in correspondence for the pointer 12 of * 10 index dials on index dial 9, and multiplying power is the pointer 14 of * 0.001 index dial, with multiplying power be the pointer 11 of * 0.1 index dial, then reflected the speed of current water meter water.Specifically, during user's water, current three pointers of water meter are according to predetermined multiplying power rule deflection, and its relation is as follows: be 360 ° of pointer 14 every clockwises commentaries on classics of * 0.001 index dial when multiplying power, represent water loss 0.001 * 100=0.1m
3, then multiplying power is changeed little lattice for the pointer 11 of * 0.1 index dial with clockwise; 11 every clockwises change 360 ° if multiplying power is * 0.1 tuning drive gear, represent water loss 0.1 * 100=10.0m
3, then multiplying power is * 10 tuning drive gear 12 meeting inverse clock deflections one little lattice, represents that the surplus water on the current water meter has reduced 10.0m
3, when the scale of three pointers indication is zero, the water content consumption that expression prestores totally, low-power scm 21 is controlled motor 23 actions with by-pass valve control, closes inlet valve 24, simultaneously, LED light 13 can the flash for prompting users must be supplemented with money IC-card again.When three root pointers, 11,12,14 indicated positions are not zero entirely, promptly represent current spendable surplus water, so the indicating mode of its surplus water is visual and clear, meet people's observation habit, its friendly interface.
In a word, the present invention has adopted and has been the water meter pedestal of U-shaped on a kind of structure, the water inlet pipe and the rising pipe that are connected as a single entity with the water meter pedestal are same direction turnover, and parallel to each other, so water meter can directly be installed in water meter the corner in house, do not take additional space, be particularly conducive to the installation in small apartment house, and after adopting U-shaped water meter pedestal, the annular inner wall of U-shaped water meter pedestal has cushioned the impact of swirling water current greatly, has reduced the influence to the water meter measurement precision of pipeline whirlpool and silt.The present invention has also adopted the inferior electric battery of built-in lithium and duct type manophyll turbine generator cycle power and charging technique, need not to change battery, therefore can not occur because the battery electric quantity deficiency, and the phenomenon that causes valve not close fully causing the subscriber arrearage water takes place.The present invention has changed the semi-mechanization of traditional mechanical water meter or IC-card water meter, the basic structure and the control mode of half-electronization fully, adopted digital water meter pointer movement based on pcb board, built-in three the micro-step motor movements independently of water meter, drive three root pointers simultaneously, thereby lengthy and tedious multi-stage mechanical numeric word wheels have been removed, mechanical dial plate directly is converted to digital dial plate, improve the reliability and the serviceable life of indication driving mechanism effectively, realized all electronic and the digitizing of IC-card water meter.Compact conformation of the present invention, on the basis of water meter pedestal, do not add plastic casing in addition, the hollow cylinder of water meter cover that it is circular and U-shaped water meter pedestal joins by screw thread, realize its integral structure, can all pcb board, digital water meter pointer movement, low-power scm, water yield sampling unit, the inferior electric battery of lithium and battery management module all be encapsulated in the hollow cylinder of water meter pedestal central top, its good airproof performance, therefore even be immersed in the water also can operate as normal for water meter, is a brand-new high-end non-contact IC card type U-shaped digital water gauge phenotype.
