Abstract
The utility model discloses an electronic remote-transferring water meter which comprises a water wheel 2 arranged in a meter body 1 and a metal sheet 3 which can coaxially rotates with the water wheel 2, wherein an induction element L connected with an electric signal converting circuit 4 is arranged at the position corresponding to the metal sheet 3, and the output of the electric signal converting circuit 4 is connected with a central processor 5 connected with a display circuit 6. The original gear system is replaced by a non-magnetic induction signal sensor, the friction generated by the transmission of the mechanical gear system is avoided, and the accuracy and the sensitivity of the water meter are improved. The number can be read conveniently, water quantity signals can be converted into electric signals in time through the metal sheet and the induction element, and the anti-interference ability is strong. The remote-transferring number is completely identical to the displayed number of the gas meter, therefore, the dispute between users and the managing department is avoided.
Description
Technical field:
The utility model relates to a kind of instrument of measuring the water yield, and especially a kind of electric signal that the water yield can be transformed into carries out the electronic remote transmission water meter that numeral shows, metering stores and carry out long-distance transmissions.
Background technology:
Traditional water meter is to be provided with the water wheels that rotate with current in the table body, water wheels rotate a series of trains by the magnetic coupling mode, metering numerical value is shown by the wheel of the mechanical count on the dial plate, not only the error of indication is big, and its metering numerical value can not carry out long-distance transmissions, management of the use of water department must send the special messenger to check meter from door to door, and the labor strength of checking meter is big, management of the use of water cost height, and management of the use of water work bothers very much.For a change the existing shortcoming of conventional water meter has the water meter that can carry out the distant signal transmission and comes out, be i.e. the pulsed remote transmitting water meter.Its principle of work is element such as tongue tube to be set send pulse signal on the rotary indicator of water meter, carries out the distant signal transmission.But this water meter does not change the basic structure of conventional water meter, and gear train assembly still exists, and exists the big shortcoming of the error of indication equally; Especially poor anti jamming capability, when running into electromagnetic interference (EMI), water meter just can not output pulse signal, makes its teletransmission numerical value and self show that numerical value is inconsistent, causes the dispute between user and the administrative authority often, and management of the use of water work is bothered more.
Summary of the invention:
The purpose of this utility model is to solve big, the inaccurate technical matters of remote transfer signal of the water meter error of indication in the prior art.
The utility model technical solution is: a kind of electronic remote transmission water meter, comprise the water wheels 2 that are arranged in the table body 1, be provided with can with the sheet metal 3 of water wheels 2 coaxial rotation, the inductance component L that is provided with sheet metal 3 corresponding sections, be connected to electrical signal conversion circuit 4 with inductance component L, the output of electrical signal conversion circuit 4 and central processing unit 5 join, and are connected to display circuit 6 with central processing unit 5.
Have sealant, inductance component L to place in the Probe positioning cover 7 outside the described sheet metal 3, Probe positioning cover 7 joins with the loam cake 8 that places table body 1 upper end.
Be provided with housing 9 in the upper end of described loam cake 8, electrical signal conversion circuit 4, central processing unit 5 and display circuit 6 place in the housing 9.
The utility model is compared with prior art, has the following advantages:
1. substituted original gear train by non magnetic induced signal sensor, the friction of having avoided the mechanical gear systems communicate to produce, the precision and the sensitivity that have improved water meter;
But 2. single-chip microcomputer storing data information, and have self check, self-picketing, self-recovering function, improved the reliability of water meter; Single-chip microcomputer adopts the RS-485 communication interface, can form multiple communication network, carries out the distant signal transmission, is convenient to the management of management of the use of water department, can reduce the management of the use of water expense.
3. sheet metal, inductance element can become electric signal with water yield signal in good time, single-chip microcomputer place with water meter table body be in the housing of one, antijamming capability is strong, makes its teletransmission numerical value and self show that numerical value is in full accord, avoids producing between user and the administrative authority dispute for this reason.
4. LCD has substituted the mechanical count wheel, simple, the easy row of reading.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the circuit block diagram of the utility model embodiment.
Embodiment:
As shown in Figure 1, 2: 1 is the table body, mounting means with conventional water meter is installed in water wheels 2 in the table body 1, an end that is arranged on the axle 10 in the water wheels 2 is placed on the support 11, on water wheels 2, fix a sheet metal 3, guarantee sheet metal 3 and water wheels 2 coaxial rotation, and with epoxy resin with sheet metal 3 sealing, in case water erosion sheet metal 3.Upper end at table body 1 is provided with loam cake 8, between table body 1 and the loam cake 8 sealing ring 12 is installed, and nut 13 is connected as a single entity loam cake 8 and table body 1.Probe positioning cover 7 is fixed on the loam cake 8, and inductance component L places in the Probe positioning cover 7, and is corresponding with the position of sheet metal 3.Be parallel with capacitor C with inductance component L, inductance component L and capacitor C and interface microcontroller circuit constitute electrical signal conversion circuit 4, and the output of electrical signal conversion circuit 4 and central processing unit 5 join, and are connected to display circuit 6 with central processing unit 5.Electrical signal conversion circuit 4, central processing unit 5 and display circuit 6 all place in the housing 9 that joins with loam cake 8.
Principle of work:
Inductance component L and capacitor C constitute antiresonant circuit, when resonant circuit vibrates to the spatial emission electromagnetic wave, electromagnetic wave can be decayed by sheet metal 3 in the space, rotate (during water) as sheet metal 3 with water wheels 2, the distance of inductance component L and sheet metal 3 will change, 3 pairs of attenuation of Electromagnetic degree of sheet metal also will be the cycle variation, inductance component L then can receive the different electromagnetic wave of attenuation degree in good time, change the output signal of resonant circuit, by interface circuit with data delivery to central processing unit 5, central processing unit 5 can be finished various operation of data, store and handle, send various sequential level control display circuit 6 video datas, control input interface and communication, circuit operate as normal such as power management.The water meter power circuit comprises inside and outside power supply switching, voltage stabilizing, power supply distribution, reserve battery and battery electric quantity detection etc., makes water meter that sufficient power supply powered operation be arranged.As must change battery the time, the data storage function of central processing unit 5 can guarantee that also data do not lose.
