RESUME:

The invention relates to a digital analog optoelectromagnetic system for counting the consumption of a fluid, which comprises a transmitter set, a receiver set, a shelf and remote billing means. The transmitter comprises an element, within which the turbine rotates driven by the passage of the fluid to which it has magnetic poles that induce, in an electronic circuit mounted on the same support, changes in the electromagnetic quantities, which are then analyzed and communicated by cable to the receiver, provided with a housing with inspection opening that houses the · reading display and the reading pins; the mentioned re /

The receiver receives a message in a code appropriate to the desired volume unit according to the turbine speeds, and the $ referred receivers, in variable number, are mounted on a shelf equipped with suitable electronic circuits and a modem unit to provide data from each accountant to a remote billing processing center. \

The Invention Patent to which this present specification refers is intended to guarantee the exclusive exploitation and ownership throughout the national territory of an analogue, digital optoelectromagnetic system for counting the consumption of a fluid, whose innovation represents an obvious and substantial improvement over all existing knowledge on this technical field.

The present invention is intended to be perfected ¹ and simplify the operating conditions of consumption meters of a fluid through a digital optoelectromagnético analogue system, which measure possibiliua, with extreme accuracy, the volume of fluid flowing through a pipe, determining, whenever desired, the volume used in individualized applications or in generic consumption, then relaying the reading values to a remote reception device, thus enabling its processing and even billing, or any other type of operation electronic or electromechanical that may be necessary. The present system provides significant advantages compared to any others known in this area,

μ ..

among which we can emphasize the elimination of malfunctions, since it does not have any mechanical transmission elements, such as toothed crowns or toothed pinions, etc. which may be subject to damage caused by use or malfunctions which, in the end, will eventually result in measurement errors as time goes by.

V system for counting the consumption of a powder fluid; sui the same precision, whatever the circulation path of the fluid, this means that this system counts upwards when the fluid circulates in one direction and counts downwards when the fluid circulates in the opposite direction.

One of the particularly interesting features of the present invention is the ease with which it is possible to replace or replace the rotor or turbine, without the need to disassemble any part of the meter itself, since the said mechanical element is totally independent from the set of data communication, thus avoiding any possibility of leakage or even incorrect manipulation; for this purpose, the rotor or turbine, being specially designed, which is driven by the fluid current, is equipped with some magnetic poles which transmit some changes of an electro-magnetic magnitude to a totally independent electronic circuit, without limitations frequency, which are then analyzed in said circuit and transmitted with a special coding through the connection line from the transmitter to the receiver since both are spaced apart.

The proposed system comprises the following elements:

a) Emitter assembly, circulation flow meter, which uniformly analyzes the direction of the flow path of the stream. The emitting body is entirely sealed, since the

tube through which the fluid passes is made in one piece;

b) Receiver and shelf set, suitable for receiving the appropriate coding from the emitter to specify the volume unit processed, adding or subtracting it, according to the information received from the emitter, while the receiving elements of the con / together with the counter, they are grouped on the shelf, which are formed by a visualization panel, in which the elements detected by the emitter are read remotely;

ç)

Dipolar power supply cable, which does not require bli. approach, nor does it need to take into account its personality; and

d) Remote billing equipment.

In order to enable a better understanding of this specification, a series of drawings are attached here that illustrate an example for the implementation of the system of the invention, an example that is described and represented by way of example only and, consequently, without any limiting character.

⁵ '

According to this invention, the meter is formed by two separate bodies, clearly differentiated between the emitter and the receiver. They constitute the parties. of the installation, a set that completes a bundle on a shelf, a bipolar electrical cable and a microprocessed remote billing system.

This means that the consumption counting system consists of the following elements:

a) Issuing set

b) Receiver set

c) Shelf

d) Electric power cable

e) Remote billing system

a) Issuing set

It comprises a tube (1), figure 1, which is hexagonal in its external part and of cylindrical configuration in its internal part, in whose coaxial interior it has a cartridge (2) in which the directional nozzles (3) and the shafts that support the turbine devices (4) and the turbine (5) · The aforementioned cartridge (2) is installed in a housing that is intended for it inside the tube (1), thus being perfectly fixed there. It also has, on its front side, a filter (6), which also acts as a seal on its smooth part.

tube (1) has, on its external part, some notches (7) perpendicular to its axis that rest on the loops (tí) that, in turn, are fixed on the outer covering (9) and on the box (10) that contains the electronic installation. The installation is then closed with the cover (11), which has some notches (12), through which the latches of the lining (9) pass, thus being in a perfect assembly position and allowing the closing of the installation.

The flow of the fluid stream, which is intended to tell me, passes freely through the cartridge (2) and causes the turbine (9) to rotate, incorporating special characteristics. It has some magnetic poles that induce, in the electronic circuit housed in (10), some modifications of an electromagnetic quantity without frequency limitation. These changes are analyzed in the aforementioned circuit and are then transmitted, with a special coding, through the line I read. the receiving sender. It also analyzes the direction of rotation of the turbine, in order to discriminate the direction of the circulation of the fluid current. This system design allows for an easy change or replacement of the mechanical complex, without the need to disassemble any part of the counter.

In Figure 2, you can see the longitudinal section of the transmitter.

b) Receiver set

It is formed by a box (14) that has some conical lateral guides (25) to center it on the notches on the shelf for this purpose. In its liquid crystal indicator (2CD), there is a chamfered part (16), which is the only area that is in contact with the shelf, thus allowing the easy placement and removal of both (figure 4).

The box (14) has a rear cover (1?), Which has a cavity that allows its perfect mechanical fixation on the shelf, and has the necessary number of pins to connect said cavity to the shelf and ί to the external lines.

The receiver is supplied with an appropriate coding, coming from the emitter, depending on the division that it must perform in relation to the turbine speeds to specify

stay the desired volume units, such as cubic meters, liters, gallons, etc., by adding or subraining it according to the information transmitted by the emitter.

There is also a system of supervision for the transmission line, in order to detect any anomaly of the receiver or for its handling. We also analyze the ones without rotation, to the right or to the left, to verify the relevant addition or subtraction, and also to verify the point at which the meter starts operating at a certain level.

All this information is displayed on the display device: the liquid crystal display (2CD). This liquid crystal display (2CD) has two sets of digits of different size, so that you can perfectly differentiate the units in which the measurement is expressed. On its lower right side, it shows a P to indicate any failure or anomaly, with some sectors in sequence sequentially arranged to indicate that the meter is working correctly.

The receivers have serial outputs in binary encoded top code (3CD), to transmit all their information through the shelf, a telephone line, optical fibers or radio, as necessary, to a data processing center. With this system, it is possible to carry out, easily and economically, each reading of the meter consumption and, automatically, its billing.

c) Shelf

This is the element on which all the receiving elements of the counter set are grouped (figure 4). The shelf consists of a display panel, on which remote reading of the elements detected by the transmitter is carried out

The shelf consists of a rectangular box

home (18) in which its sides (19) are larger to support the inner box and allow it to have a rotating movement. Said inner box, in turn, is formed by a U-shaped plate (20), which has internal lips; which serve to hold the flat part (21) supporting all the connectors and having a housing on its bottom for the batteries.

All lines that come out of each of the sending units are connected to these connectors.

The box (18) has some holes for the entry of cables and for their subsequent fixation.

Together with the flat part (21), a printed circuit support plate is mounted, with all the appropriate circuitry, to indicate its correct functioning, as well as a Modem unit to output all data from each meter. , its working state and the working state of the shelf itself and its batteries.

battery fixing housing (22) has a system, through which the batteries are disconnected from the shelf circuit during storage periods, by simply pressing its fixing screws to return them to operation. That is, the cover itself is the switch.

In the front part of the panel (20) there are openings that are covered with a grooved synoptic part »so that, with light pressure, the housings are available for placing the exact number of receivers for each installation. I

The shelf has a means of producing signals, which indicates whether or not the system is in its normal operating state and whether there is a lack of voltage and whether

the batteries are being discharged or are no longer charged.

This set is totally protected with a cover (23), which has a window to see all the set, which is fixed by means of sealing screws.

d) Electric power cable

The electrical cable that connects to a bipolar cable and does not require shielding due to its polarity.

f '* · emitter to the receiver and even if taken in coi

e) Remote billing system

Figure 5 illustrates a schematic of the transmission and processing system to provide the information contained in the receivers.

The digital analog optoelectromagnetic system for counting consumption is a remote reading system for two reasons:

a) the transmitter and the receiver are two independent bodies, connected by means of a cable. This fact allows the receiver to be placed in the most appropriate place, centralizing the reading of all invoices on the corresponding shelves.

b) for their part, the receivers have outputs in series with binary coded decimal code (BCD), prepared for their connection to an ivlodem unit, from which their information can be sent to a data processing center the following operations are carried out:

- Reading order of all counters connected to the center and their storage on a magnetic disk.

i

- Processing all information received.

- Invoicing and printing of important invoices.

- List of meters that have any irregularities for later verification. í

- Checking the function of the shelf and detecting any manipulations.

The terminals (24) of the emitting bodies (E) have no polarity in relation to the transmission lines and there is no need for a special cable for these lines.

There are four options for making the connection between the sender (s) and the receiver (s) according to the following requirements:

Transmission of information from each emitter to its most important receiver (R) placed on a panel: 25. That is, the receiver offers direct reading of data from its respective transmitter (E).

This is the standard connection system.

2) assembly of several emitters in parallel (E1-E2-E5-E4-), obtaining the addition of the consumption of fluid in circulation through the four mentioned emitters, which is totaled in the receiver R1. It is thus possible, for example, to obtain the total volume of consumption, in which there are fluid inlets coming from more than one installation, directly from only one receiver.

3)

Interleaving of an R2 receiver in required, which shows the indication of the series with the emitter or emitter line

Figure 5 shows emitters, E) and Eô.

This system, for example, allows a user to have his own receiver to know how to control his total consumption, or part of the consumption, from any time he wishes. That is, the repeater can be inserted into the total or partial number of counters. Figure 5 shows the R2 repeater offering the consumption values

to counters E5 θ E6, and on the shelf (25) we have the total consumption value of E5, E6 and E7.

4) Total sum, in only one receiver, of all readings of the distribution of a fluid through an annular system. This is achieved by getting one of the emitters to add and the other to subtract, showing the differential value in a receiver. '

Until now, the transmission of information from the sending body to the receiving body placed on the shelf, or wherever the user wishes to see it, has been described. From now on, the transmission of information from the receiver to the information processing center will be analyzed.

Each receiver has a free opening for admission and a BCD serial output (with decimal code encoded in binary), through which it transmits all the information it contains. The counter system has three reading options;

1) Visual reading of the receiver centered on the most important shelf (25).

2) Sequential reading and printing in situ using a special equipment.

5) Sequential remote reading by means of a system, through which the information is transmitted by a telephone line, or by optical fibers, or by radio waves, to a processing center. The said center is basically formed by a specially designed computer (26), which controls and memorizes all the information and the billing and printing systems (27).

Some take place in the IR (receipt printing) that does its own billing, while others, IE, take care of the printing counters, in which any anomaly (of failure or manipulation), that is, the invoicing and verification of all counters is done automatically

automatically; the computer (26) performs the reading sequentially, through an order, of all the counters on the shelf and, through the billing program, delivers each reading to the user in question. This information is processed and can be printed in the desired format.

Having just described and presented the topic

this Invention Patent with sufficient breadth and clarity for its realization, here it is declared that it is innovative although accidental changes can be introduced in the details, both of the system and its components, always respecting its essentiality. unchanged.
