Description
Technical field
The utility model relates to a kind of water meter, particularly a kind of large-diameter water meter.
Background technology
Water meter is the instrument of measuring discharge.The integrated flow that mostly is water is measured.Generally be divided into volumetric water meter and velocity type water meter two classes.The former accuracy is high than the latter, but high to water quality requirement, and is easily blocked when impure in the water.The instrument of record tap water water consumption is contained on the water pipe, and when the user discharged water, the water yield passed through was pointed out in the rotation of pointer or character wheel on the table.
Unique measurement instrument that water meter is settled accounts as water undertaking and user, in water system, play extremely important status, especially the management of large-diameter water meter (referred to as large table), very important especially, so-called large-diameter water meter refers to the water meter that nominal bore 50mm is above.Existing intellective IC card large-diameter water meter is a kind of new water meter that utilizes modern microelectric technique, Modern Transducer Technology, intellective IC card technology water consumption to be measured and carried out the transmission of water data and settlement bargain.This generally only has flow collection with conventional water meter compares with the function of mechanical indicator demonstration water consumption, is a very large progress.Generally be applied to the metering of the total water amounts such as community, village, enterprise.
The metering section of tradition IC-card water meter is to adopt pulse single-transmitting watermeter and cable transmission flow pulse, yet burst transmissions is subject to external electromagnetic interference, so that mistake appears in data on flows in transmission course, even can't this mistake of verification, burst transmissions also is subject to the cable length restriction, so the IC-card controller can only be installed near the table well, this supplements with money at a distance with the equipment Alternating Current Power Supply for the user and brings difficulty.
How a kind of large-diameter water meter is provided, can overcomes above-mentioned technical matters, become the technical matters that needs to be resolved hurrily.
The utility model content
The technical problems to be solved in the utility model is how a kind of large-diameter water meter is provided, and has solved data transmission procedure and has gone out existing mistake and the restriction that is subject to length of cable, and then brought the difficulty of use to the remote subscriber.
For solving the problems of the technologies described above, the utility model provides a kind of large-diameter water meter, comprising: water meter, motorized valve, broken string pass valve control and IC-card controller, controller for water meter, wherein said controller for water meter are arranged at described water meter top; Described motorized valve is connected with described controller for water meter by cable; Broken string is set between described controller for water meter and described motorized valve closes valve; Described IC-card controller is connected with described controller for water meter.
Preferably, described motorized valve is that bore is the above electric butterfly valve of DN40.
The utility model detects and is connected the IC-card controller and is connected with controller for water meter by the RS485 communication bus the power supply of motorized valve, and its communication distance can reach more than 500 meters.Like this, the IC-card controller can be installed in any occasion away from the table well, and this has not only made things convenient for the user to supplement with money, has also solved the Power supply problem, therefore, and the interference of having avoided long cable transmission pulse to bring.
