Description
Technical field
The utility model is related to the intelligence that a kind of water meter more particularly to a kind of inside are equipped with two-way detection sensor component
Water meter.
Background technology
Intelligent watermeter is on the basis of mechanical water meter, and mechanical information is converted to electronic signal, so as to complete intelligence
The remote transmission of data of water meter or long-range survey are copied, and be aided with mating computer data processing system, data summarize whole
Reason carries out system administration to water meter.Therefore the key technology of Intelligent watermeter is exactly sensor technology.Common intellectual water meter passes
Sensor mainly includes following several, and one kind is tongue tube sensor, installs tongue tube and magnet additional in mechanical water meter, using dry
The reed of reed pipe circulating open close under the ringing of magnet, so as to export metrical pulse signal；One kind is Hall sensor,
It installs Hall element and magnet additional in mechanical water meter, the sensor based on magnetoelectricity switch technology is formed, on counting scale position
Magnet with count turntable operating, it is often primary by Hall element, i.e., by Hall element export one counting pulse；One kind is
Wiegand sensor, according to distinctive magnetic resistance damping characteristics, spike signal that output duty cycle differs needs to increase additional
Pulse shaper, circuit is complicated, and poor reliability, power consumption is bigger, inaccuracy is measured in small flow, it is more demanding
Operating point magnetic field proposes its installation site very high requirement；One kind is photoelectric sensor：It is installed at the turntable of mechanical water meter
One photoelectric converter, there is a groove on turntable, turntable every revolution, groove by light it is defeated when converter complete primary electricity
Conversion exports a counting pulse.What these types of sensor was sent out is pulse signal, and water meter can fall in Special use
Turn, once reversing similary generation pulse signal, the cumulative measurement of this signal system is considered as normal metering, causes indicator of water gauge meter
Amount is inconsistent with digital metering, easily makes to generate metering dispute between user and administrative department；And water meter is originally experienced extraneous vibration
It influences or since " water hammer " in water pipe causes the vibration of water meter movement, pulse sensor can all be made to send out improper pulse letter
Number, lead to pulse error, and since response frequency is low, the common scheme of digital water gauge is the speed change by gear, biography
Sensor is mounted on 10 liters of flow positions, and such water meter can only measure the total flow in a period of time, and cannot measure instantaneous stream
Amount, it is low to will result in measuring accuracy in this way；And the energy consumption of above several sensors is bigger, especially photoelectric sensor and Wei
Root sensor so that battery is short, and user and administrative department are difficult to in the battery service condition with water meter such as finger
The palm, once battery capacity is insufficient, water meter measurement out of service may either cause user that can not use water or water supply management department
Door suffers a loss due to sensor of water meter does not measure；And tongue tube sensor, Wiegand sensor and photoelectric sensor failure rate
Height, maintenance cost are high；Sensor module now is all mounted on the outside of water meter, the tongue tube sensor and Hall sensor in outside
Easily by magnetic interference, some people can also deliberately additional magnet generates powerful magnetic interference at watermeter shell, reach steathily
Water purpose, the sensor module mounted on outside pacify easily by ectocine, influence water meter measurement, reduce the accurate of water meter
Degree.

Shape storehouse is connected with mounting blocks, is installed inside the mounting blocks by the way that card is assigned to assign into mounting groove on the sealing annular bin
There is circuit board, TMR reluctance switch sensors are fixed on the circuit board, magnet is installed on the downside of the mounting blocks.
The magnet is cuboid, and placement direction is horizontal magnetic field.
Magnetic switch sensor is installed on the downside of the sealing annular bin, the magnetic switch sensor is far from the magnet
It is and insensitive to the magnetic field of the magnet.
The sealing annular bin is sealed using sealing.
Described two TMR reluctance switches sensors are the ambipolar TMR reluctance switches that output is latched with cmos digital
Sensor.
The magnetic switch sensor is Hall sensor or tongue tube sensor or TMR sensor.
The beneficial effects of the utility model are：The utility model improves existing water meter, by the sensor in outside
Component is placed on inside water meter, avoids being interfered by external magnetic field, improves the accuracy of water meter, avoids the hair of regimen condition steathily
It is raw.The circuit board, sensor module of the utility model are mounted on by TMR reluctance switches sensor in a sealing annular bin, close
The mode that envelope annular bin is sealed with sealing so that the water inside and outside water meter cannot avoid its waterlogged damage, virtually prolong into putting in storage
The service life of the utility model is grown.
Turned using rotatable parts such as the mutually orthogonal two TMR reluctance switches sensors detection water meter wheel rotors of sensitive axes
Emotionally condition can send out four kinds of different conditions signals, so as to obtain the rotary speed of impeller and direction of rotation, can carry out adverse current detection
And instantaneous flow detection, make accurate measurement, and it can be found that water leakage situation, sends out big flow alarm signal；Reluctance switch
Sensor can have with respect to sensors such as tongue tube sensor, Wiegand sensor and photoelectric sensors under continuously running duty
There are the characteristics of low-power consumption, high frequency sound, high sensitivity, wide measurement gap and long lifespan and high reliability, because low in energy consumption, water meter
Battery life is long, and because reluctance switch sensor life-time is long and high reliability, thus failure rate is low so that water meter maintenance cost
It is low；The utility model increases the magnetic switch sensor of detection water meter external world's magnetic disturbance, can be directed to abnormal magnetic disturbance and be detected,
Send out alarm signal and respective handling in time.
