DESCRIPTION OF THE INVENTION having as TITLE:

NEW GAS METER WITH MECHANICAL MODULE FOR MEASURING THE QUANTITY OF GAS CONSUMED AND INNOVATIVE ELECTRONIC MODULE FOR PROCESSING AND TRANSMISSION OF DATA

A) REASONS, PURPOSE AND BACKGROUND OF THE TECHNIQUE The invented device (1) is a new model of gas meter composed of a module for measuring the volume of gas, known per se, of the â € œmechanicalâ € type (2 ). This electronic module (3) has the following innovative features:

- It is made up of â € œtwoâ € power supply modules, one â € œmainâ € (4) (usually one or more long-life batteries) and one â € œauxiliaryâ € (5); the peculiarity of this `` auxiliary '' power supply module (5) is that it is activated (automatically disconnecting the main power supply module (4) which in this way will not consume energy) when it transits / passes gas inside the meter ( 1); said auxiliary module (5) does not include any battery / cell (in practice it is therefore almost `` eternal '') and is able to power the electronic module (3) (all or most of it, depending on the needs) of the new gas meter (1);

- the `` auxiliary '' power supply module (5) is also able to provide, to the microprocessor of the electronic module (3), also the count of the periodic `` consumption '' of gas by the user: in this way it will not be necessary to use additional remote measurement modules for gas consumption and therefore there will be a saving on the cost of the electronic module (3) and a lower energy consumption of the power supply module (4) of the meter (1).

The considerable advantages that the presence of the `` auxiliary '' power supply module (5) can bring to the gas companies and their customers are listed below: a) the invented gas meter (1) will have an electricity supply with very high autonomy and duration (higher than the norm);

b) the meter (1) will also be able to function in the event of a discharge or malfunction of the (long-lasting) battery supplying the electronic module (3) of the meter: in this way the data relating to the â € œgas consumptionâ € will not be lost and there will be greater â € œsafetyâ € of the plant in case of emergencies or other;

c) it will be more convenient and simpler (as an intervention procedure) to replace (if necessary) the power supply battery of the meter: the customer will not have any nuisance or inconvenience, the gas passage will not have to be interrupted and the data relating to gas will not be lost;

The gas companies will therefore have considerable savings in costs and human resources, fewer problems with their customers and greater safety. At present there are no systems similar to the present invention which are capable of providing all the advantages listed above.

B) DESCRIPTION AND OPERATION OF THE INVENTION

The invented device (1) (see figures 1 and 2) is a new gas meter consisting of a mechanical module for measuring (2) the quantity of gas consumed (module known per se, of the deformable membrane type, turbine, rotating pistons, etc.) and by an electronic module (3) for data processing and transmission. Said electronic module (3) is powered by a â € œmainâ € module (4), consisting of at least one long-lasting battery / cell (e.g. with a capacity of 13 or 18Ah and a nominal voltage of 3.6 volts) and by an innovative “auxiliary” module (5), without batteries. Said `` auxiliary '' power supply module (5) is activated (thus powering the electronic module (3) of the meter (1)) when it transits / passes gas inside the meter (1) and in this case it will be automatically deactivated / disconnected the main power module (4), whose battery will thus last much longer than the classic processing modules currently on the market.

The â € œauxiliaryâ € power module (5) is without batteries and takes advantage of the mechanical work produced inside the meter (1) during the transit / passage of gas. The mechanical work, produced by the cyclic / periodic movement of the internal measuring mechanism of the mechanical module (2) of the meter, is then transferred to the power supply `` auxiliary '' module (5) through the transmission shaft / coupling (12) of the meter, to which said module (5) is directly connected by means of the rotation shaft (14) (see figures 1 and 2). The innovative auxiliary power supply module (5) is mainly composed of the following main components (see figure 1).

1) At least one â € œtoothed wheel for multiplying revolutionsâ € (6), connected in an integral way with the joint / shaft (12) for transmitting the cyclic / periodic movement produced by the mechanical measuring module (2) when it passes gas to the inside of the counter (1); the teeth of said wheel / gear (6) are then directly connected (see figure 2) with those of the toothed wheel / gear (13) of the rotation shaft (14) of a direct current generator (7), thus obtaining in this way, thanks to the â € œdifferentâ € measurement of the diameters of said two gears (6) and (13), a multiplication, an increase, of the rotation speed of the shaft (14) of said direct current generator (7) , or an increase in the current (and / or voltage) produced at the output of said generator (7). This increase in current (and / or voltage) is necessary to allow correct operation of the entire auxiliary power supply module (5).

A `` gear multiplier gear wheel '' (6) will be chosen that has a minimum diameter (or radius) that is at least 3 times (better still if 4 or 5 or 6, etc.) greater than the diameter (or radius) of the wheel / gear (13) of the rotation shaft (14) of the direct current generator (7), thus obtaining a rotation speed of the shaft (14) of said generator (7) which is at least 3 times (or 4 or 5, etc.) higher than that of the transmission shaft (12) of said mechanical module (2) of the meter (1); in this way the number of revolutions made, in a certain time interval, by the shaft (14) of the generator (7) is at least triple (or quadruple or five times, etc.) of those made by the shaft ( 12) of the mechanical module (2), thus obtaining a higher current and / or voltage produced at the output of the generator (7). It is obvious that during manufacturing, compatibly with the construction and dimensional limits of the meter (1), an attempt will be made to obtain a `` multiplication factor '' (i.e. the ratio between the diameters of the two gear wheels, (6) and (13)) as high as possible; the ideal would be to have a multiplication factor greater than 4.

2) A `` direct current generator '' (7) (see figure 1), in which the wheel / gear (13) of its rotation shaft (14) is directly connected (through the gear multiplier of revolutions (6 )) to the coupling / shaft (12) for transmitting the internal measuring mechanism of the mechanical module (2); during the passage / consumption of gas inside the meter (1) a periodic / cyclic movement (mechanical work) will be produced (by the mechanical module (2)) which will then be exploited by the generator (7) to produce direct current necessary for the operation of the auxiliary power supply module (5). The `` direct electric current generator '' (7) is mainly composed of:

- a small â € œalternatorâ € (15), that is a small â € œalternatingâ € current generator, with fixed electrical windings and rotating magnet; the alternator (15) generates alternating current during the rotation of its shaft (14) or during the passage of gas inside the meter (1);

- a â € œcurrent rectifierâ € (16) then transforms the alternating current (produced by the alternator (15)) into direct electric current necessary for the operation of the auxiliary module (5) and therefore of the electronic module (3). For reasons of duration and safety it is preferable that the generator (7) be of the â € œbrushlessâ € type, or â € œwithout brushesâ €, in order to avoid any dangerous sparks and wear of the brushes (usually graphite charcoals or other ) which would reduce the operating time of the entire auxiliary module (5). The direct current generator (7) uses the movement (periodic / rotary) of the measuring mechanism (2), during the transit / passage of gas inside the meter (1), to generate (by means of the alternator ( 15)) alternating current, then transformed (by means of the rectifier (16)) into direct current which will then be used (by the auxiliary module (5)) to power the electronic module (3). Among the various possible and preferable types to make the â € œcurrent rectifierâ € (16), a classic â € œdiode bridgeâ € can be used (e.g. 4 diodes arranged in the classic â € œGraetz bridgeâ € configuration, or 6 diodes to rectify a three-phase voltage, etc.) or integrated circuits of the “bridge rectifier” type such as eg. those of the DB series (from DB101 to DB107).

3) An integrated circuit â € œcharging pumpâ € (8), used to increase, raise, the value of the voltage taken at the output of the direct current generator (7), especially in the case of low gas flows, or in case of low / poor mechanical work produced by the metering module (2) of the meter (1), which occurs in the event of low gas consumption by the user. The â € œcharging pumpâ € circuit (8) is inserted between the output of the direct current generator (7) and the input of a step-up dc-dc converter (9) (see figure 1) , in such a way that at the input (of the charge pump (8)) there will be the voltage produced at the output of the generator (7) (produced thanks to the periodic mechanical movement of the measuring mechanism (2) of the meter (1)) and at the output (always of the charge pump (8)) there will be the voltage (increased, raised) to be supplied then to the input of the dc-dc converter (9) to ensure correct operation. Therefore, thanks to the â € œcharging pumpâ € (8) circuit, you will get a voltage (and / or current) sufficient to make the â € œdc-dc converterâ € (9) integrated circuit always and correctly work.

The integrated circuit â € œcharge pumpâ € (8) is mainly composed (as an operating principle) of a capacitor and a Mos-type transistor, and increases its electric potential by switching the transistor on / off. Said charge pump (8) will allow the correct operation of the â € œdc-dc converterâ € (9) (which, in order to function correctly, needs a minimum input voltage equal to about 0.8-0.9 volts) even in the case of very low voltage values (supplied by the direct current generator (7)), even as low as 0.3 volts! These low voltage values (0.3-0.4 volts) are usually obtained when the meter (1) operates at low gas flow rates, ie when the user consumes little gas. A good â € œcharge pumpâ € on the market, which allows you to work even with input voltages of only 0.3 volts, is the integrated S882Z from Seiko.

4) A â € œdc-dc converterâ € (9) integrated circuit of the â € œstep-upâ € type, used to stabilize and raise, at least to a minimum indispensable value, the working / power voltage (and / or current) to be supplied to the electronic module (3) for processing and transmitting data of the meter (1), in order to guarantee its normal and correct functioning. A step-up type dc-dc converter is usually used to provide a (stable, constant) output voltage higher than the input voltage; eg. with an input voltage of 0.8-0.9 volts, an output voltage of 3 volts or more can be obtained. Among the many valid step-up dc-dc converters available on the market, the integrated series S8353-54 from Seiko, or other similar ones, are optimal and totally compatible with the load pump (8).

5) One â € œswitch / commutator / electronic switchâ € (11), used to activate / select, automatically, the â € œauxiliaryâ € module (5) or the â € œmain moduleâ € (4), as the power source of the module (3), being activated / switched, (from said electronic switch (11) - see figure 1-) the use of the â € œmainâ € power supply module (4) preferably only when the voltage (and / or current ) supplied by the auxiliary module (5) becomes insufficient to power and operate correctly (all or part of) said electronic module (3) for processing and transmitting data of the meter (1). Among the various circuits and components on the market, which can be used to make the switch (11) (switch, electronic switch), it is preferable to use an integrated type â € œmicroprocessor supervisory circuitsâ € (microprocessor supervision circuits); in this way it will be possible to avoid having useless potential drops, even higher than 1 volt (due for example to the use of diodes to make the switch / swtich) which would dangerously lower the value of the voltage available for the operation of the electronic module (3). Among the many switches of the "microprocessor supervisory circuits" type on the market, those of Maxim (Max793 / 794/795, operating at 3 volts), those of SGMicro (SGM803 / 809), etc. are certainly valid.

6) The power supply `` auxiliary '' module (5) is also (preferably) also composed of at least one `` super capacitor '' (10) (see figure 1), i.e. a high capacity capacitor, used to store a certain quantity of electric charge when said auxiliary power supply module (5) is in operation, or when mechanical work is produced by said measurement module (2), or when there is passage of gas inside the meter (1) . Among many supercapacitors on the market, those of the Nec Tokin FG and FYD series, those of Maxwell (boostcap series), etc. are certainly valid. It will be the storage capacitor (10), as long as it has sufficient charge, to power the electronic module. (3).

Although not absolutely necessary, it is preferable and advantageous that said supercapacitor (10) (for charge storage) is present in the auxiliary power supply module (5).

The electronic module (3) (for processing and transmitting data of the meter (1)) is (preferably and advantageously) powered by the â € œauxiliaryâ € module (5) as long as said module (5) has sufficient voltage (and / or current ) to power the electronic module (3); this could happen, for example, when there is passage of gas inside the meter (1) (so that the periodic movement of the measuring mechanism (2) produces, through the generator (7), sufficient electric current to power the module (3)), or when there is no gas passing through the meter (1) but the supercapacitor (10) (of module (5)) is still sufficiently charged to power the electronic module (3). Vice versa, the electronic module (3) will be powered (by automatic switching via switch (11)) by the power supply module `` main '' (4) for the entire period of time in which the auxiliary module (5) is no longer able to to power the module (3) (with sufficient voltage and / or current); this could happen, for example, in the case in which there is no transit / passage of gas inside the meter (1) (or said passage of gas is insufficient to produce a minimum current) and the supercapacitor (10) of the the auxiliary module (5) no longer has sufficient charge to power the electronic module (3) directly and correctly. The activation (i.e. the selection / switching) of the `` auxiliary '' module (5) or of the `` main '' module (4), as power source of the electronic module (3), will take place automatically by means of the electronic switch (11 ), which will activate the `` main '' module (4) only for the entire period of time in which the voltage (and / or current) coming from the `` auxiliary '' module (5) is no longer sufficient to power correctly the module (3).

With this operating mode, the long-lasting battery of the â € œmainâ € (4) power supply module will therefore be used only when strictly necessary; in this way the autonomy and duration of the electricity supply of the meter (1) will be very high, much more than what the â € œotherâ € devices known and / or on the market, without the innovative module, could obtain Power supply auxiliary (5) referred to in the present invention.

The electronic module (3) also counts, during the transit / passage of gas inside the meter (1), the total number of positive and negative half-waves of the alternating current drawn from the alternator output (15) ( see connection (17) in figure 1), to then calculate, through appropriate multiplication with a predefined / predetermined calculation coefficient, the â € œquantity â € of gas consumed by the user in a given period of time. Furthermore, the â € œspeed of rotationâ € of the alternator shaft (15) (or rather the number of positive and negative half waves of the alternating current produced in a certain time interval) can be used to calculate the â € œflow rateâ € € of gas transited in a certain time interval (minute, hour, etc.), as well as possible gas `` leaks '' in the event that there is an uninterrupted, continuous count of positive and negative half-waves ( that is, without any break or interruption) that goes beyond a set time limit. The electronic processing and data transmission module (3) of the meter (1) is usually and mainly composed of at least one microprocessor, memories, control and management circuits, buses, input-output connections, doors, displays, keys, modules of remote reading and remote management, such as meter, interception solenoid valve and volume corrector (by means of a temperature and pressure sensor), from one or more data transmission / reception modules in radio frequency and / or cellular telephony, and so on.

The electronic module (3) is also called the â € œtelemeasurement / remote readingâ € and / or â € œtelegestioneâ € module. The mechanical measuring module (2) of the meter (1) (with a deformable membrane type measuring mechanism, turbine, rotating pistons, etc.) is not detailed as it is already known.

Summary of the invention

The invented device (1) is a â € œnew gas meterâ €, consisting of a mechanical module for measuring (2) the quantity of gas consumed and an electronic module (3) for processing and transmitting data; the electronic module (3) is powered by a `` main '' power supply module (4) (consisting of at least one long-lasting battery), and / or by an `` auxiliary '' module (5) (without batteries), which is activated (thus powering the electronic module (3)) when the gas transits / passes inside the meter (1), and in this case the main power supply module (4), whose battery it will thus last much longer.

The `` auxiliary '' power supply module (5) (without batteries) exploits the mechanical work produced (by the measurement module (2)) inside the gas meter (1), during the transit / passage of gas ; It is made up of:

- at least one â € œtoothed wheel for multiplying revolutionsâ € (6), connected in an integral way with the joint / shaft (12) for transmitting the periodic / cyclic movement produced by the mechanical module (2) for measuring the gas in transit to the inside of said meter (1), then the teeth of said wheel / gear (6) being directly connected with those of the wheel / gear (13) of the rotation shaft (14) of a direct current generator (7), thus obtaining, thanks to the â € œdifferentâ € measurement of the diameters of said two gears, (6) and (13), a multiplication, an increase, of the rotation speed of the shaft (14) of said direct current generator (7), or an increase in the current and / or voltage produced at the output of said generator (7);

- a â € œdirect electric current generatorâ € (7), in which the wheel / gear (13) of the rotation shaft (14) is directly connected, by means of said gear wheel for multiplying revolutions (6), to the joint / shaft (12) for transmitting the (periodic) movement produced by said mechanical measuring module (2) during the passage / consumption of gas inside said meter (1);

- an integrated circuit â € œcharge pumpâ € (8), used to increase, raise, the value of the voltage taken at the output of said direct current generator (7), especially in the case of low gas flows, or in case of low mechanical work produced by the measurement module (2), thus obtaining, at the output of said charge pump circuit (8), a voltage and / or current sufficient to make an integrated circuit always and correctly operate. € œdc-dc converterâ € (9) of the step-up type;

- a â € œdc-dc converterâ € (9) integrated circuit of the â € œstep-upâ € type, used to stabilize and raise, at least to a minimum indispensable value, the working voltage and / or current / power supply to be supplied to said electronic module (3) for processing and transmitting data of said counter (1), for its normal and correct operation;

- a switch / commutator / electronic switch (11), used to automatically activate said `` auxiliary '' module (5) or said `` main '' module (4), as a power source for said electronic module (3), being activated, by said electronic switch (11), the use of said `` main '' power supply module (4) only when the voltage and / or current supplied by the `` auxiliary '' module (5) becomes insufficient to supply and making said electronic data processing and transmission module (3) of the gas meter (1) work correctly.

The power supply `` auxiliary '' module (5) is also (preferably) composed of at least one `` super capacitor '' (10), i.e. a high capacity capacitor, used to store a certain amount of electrical charge when it is in function of said auxiliary power supply module (5), that is when mechanical work is produced by said measurement module (2), or when there is passage of gas inside said meter (1).

The â € œtoothed wheel for multiplying revolutionsâ € (6) has a minimum diameter (or radius) at least 3-4 times greater than the diameter (or radius) of said wheel / gear (13) of the rotation shaft (14) of said direct current generator (7), thus obtaining a rotation speed of the shaft (13) of said generator (7) at least 3-4 times higher than that of the transmission shaft (12) of said module mechanical (2) of the counter (1), i.e. a â € œnumber of revolutionsâ € at least triple or quadruple, and therefore a greater current and / or voltage produced at the output of the generator (7).

The `` direct current generator '' (7) is mainly composed of an `` alternator '' (15), generating alternating current, and a `` rectifier of current '' (16) which then transforms said alternating current into direct current .

The integrated circuit â € œcharge pumpâ € (8) is mainly composed of a capacitor and a Mos-type transistor, and increases its electric potential by switching the transistor on / off, thus allowing the charge pump (8), the correct operation of said â € œdc-dc converterâ € (9) even in the case of very low voltage values (supplied by said direct current generator (7)), even as low as 0.3 volts.

The switch circuit / commutator / electronic switch (11) is preferably composed, to avoid unnecessary voltage drops, by an integrated type â € œmicroprocessor supervisory circuitsâ € (microprocessor supervision circuits).

The electronic module (3), for processing and data transmission, is powered by the power supply module (5), as long as said module (5) is able to supply sufficient voltage (and / or current) to supply said electronic module (3). The electronic module (3) is instead powered by the `` main '' power module (4) for the entire period of time in which the `` auxiliary '' module (5) is no longer able to supply sufficient electrical power (voltage and current) to power said electronic module (3).

The electronic module (3) also counts, during the transit / passage of gas, the total number of the positive and negative half-waves of the alternating current drawn at the output of said alternator (15), to then calculate, through appropriate multiplication with a predefined calculation coefficient, both the â € œquantity â € of gas consumed by the user in a given period of time, and the various â € œhourly flowsâ €, and to detect any â € œgas leaksâ € determined by a count â € œcontinuous / uninterrupted '(i.e. without pauses) of said positive and negative half-waves of the alternating current generated by said alternator (15).
