Description

METHOD AND ELECTRONIC SYSTEM FOR INSTANT CREATION AND STORAGE OF HISTOGRAMS OF CONSUMPTION IN DRINKS OF DRINKING WATER FIELD OF THE INVENTION The present invention relates to the technical field of drinking water supply measurement and control systems.

BACKGROUND Generally, the private and governmental organizations responsible for the supply of drinking water use mechanical measuring instruments to establish the payment to be made to their subscribers for the service provided; As the performance of the meter is reduced with the wear of its components, maintenance policies are established based on the total volume recorded or the time that has elapsed since its installation. The wear of the measuring equipment is not only a function of the registered volume and the quality of the water; above all it is of the instantaneous expenses to which said volume passes through the meter. The performance is not only a function of the accuracy of the meter, but of the proportion of the volume that according to the consumption pattern of each user, is measured with the specific accuracy of the device to each instantaneous consumption expenditure. Having a histogram of real instantaneous expenses of consumption to which a meter has been subjected in service, would allow to optimize the useful life of the devices _______ A ^ jj-A ^^^^ ,, ^ ______.__., _. .. > _, __ "_ ..____ __, .__.._...___» ___. * -._, _____..._ "_" _ ^ ___- __ ^^ JS ».l¿ j * W ** Jß¡? in such a way that it is repaired or replaced at the most appropriate and economic time for the operating agency, taking into account both the income and the relative investments. It would also serve to ensure that the sizing and technology of the measuring equipment are adequate. On the other hand, an important element to consider in the supply of drinking water, is the distribution of demand throughout the day, since the infrastructure and operation are planned to be able to offer a good service in the peak hour of the day of peak demand. This results in the "underutilization" of installed capacity during most of the year, and the need to increase this capacity, with the same criteria, hardly recorded demographic growth or demand. For the operator, it would be very useful to know the consumption volumes recorded in different periods of the day, so that in addition to providing elements for a better planning of the infrastructure and the operation, it would allow to establish different rates for different consumption schedules, such as is the case of telephone and electric power companies. With this, a change in demand that contributes to making the operation more efficient, and to take more advantage of the existing infrastructure, even to the degree of deferring investments, could be induced via price. It is known the case of electric power supply service companies, which have implemented incentive programs and penalizations to their large users in order to maintain their networks of ?gave__. _ * ^ distribution with the optimal dimensions and not incur unnecessary investments. The programs implemented are intended to distribute the demand by maintaining a stable average consumption during the day, as well as ensuring that the energy transported is consumed efficiently by the user. Normally the consumption of electrical energy required in the distribution of water represents one of the largest operating expenses of the operating agencies and these are usually considered as very large users. It then becomes necessary for the water operators to control their electric power consumption, a difficult task to implement if the users have a consumption behavior during the day that is completely different to that of the operator. Being able to charge the service with hourly rates, therefore, would also help to link the water consumption of the subscribers to the times that best suit the operator from the point of view of the cost of energy. Another element to consider regarding the profitability of the operating agencies, is the productivity and reliability of the methods used to read the consumptions of the users with which the billing and collection processes begin. To date, several electronic reading technologies have been developed that are available in the market, which offer enormous benefits. However, for many operators, the cost-benefit ratio of their implementation does not yet justify them.

IJ_U1__ _____ t -rt-f r «. ~ T-tfft_ ~ .ii There is currently a considerable number of devices which, in the technical field to which the present invention refers, perform electronic reading functions of the total volume consumed; however, they offer little additional information. An electronic reading system that, in addition to recording the total volume consumed, provides details of the instantaneous expenditure and the schedules in which it has been given, would be a very useful tool to obtain all the above-mentioned benefits. On the other hand, there are equipment that allows the acquisition of data for the sizing of distribution networks, obtaining consumption profiles and selection of measuring equipment, however they are used in a timely and zoned manner and for short periods of time that could not be even representative, besides having a high cost. Trying to apply these technologies to analyze the behavior of all users would require, in addition to huge investments, transmission channels with high bandwidth by the large amount of data they generate, or very long and impractical reading times. One of the objectives of the present invention is to offer an electronic reading system for drinking water intakes that provides, in addition to the total volume consumed by the user, profiles of the instantaneous expenses and of the periods of the day in which this occurs, starting from of mechanical measuring equipment, equipped with pulse emitters. Another objective of the present invention is to provide said information in a compact manner, so that t __-_ fc_ < i _____ ^ __ j___ > , _L ^ ___ e_Ji _... .._,., ___.._... _________ ___ "_ ___a_,.,. ^ _.__, .j, _, _____ _ _fc. , that allows a fast and practical transmission, in a device with years of autonomy and appropriate even for adverse installation conditions. Another objective is to give organizations operating potable water systems, elements to make their activity more profitable, through more informed programs for the maintenance of meters, better use of installed capacity, efficient distribution of supply throughout the day and even for the deferral of investments. Another purpose of this invention is to provide the operator with information that allows him to estimate, from the known errors inherent in the precision of the mechanical meters, different instantaneous costs, the volume of water that is currently considered as physical loss, and even to compensate in the individual invoicing, inferring the water supplied not measured. Still another objective of this invention is to provide the operator with means that allow him to apply more creative tariff schemes, oriented to the efficient and sustainable use of drinking water. The System of the present invention comprises a Microcontroller device, which makes it possible to modify the actions carried out, according to market requirements or special needs of the operator. The invention can be installed in a meter that provides the means and signals necessary for its interconnection, of which there are de facto standards that a large number of manufacturers have adopted. The flow of water is £ ___ _Lj___ i _-____ i * - yf > * - counted by the meter, which, whenever it registers a certain volume, emits a signal that is coupled to the circuitry of the System. Each pulse emitted by the meter is sensed by the System of the present invention and serves as a reference to measure the volume consumed and the time difference between the occurrence of the pulses is used to determine the expenditure. At the occurrence of each pulse, the invention "wakes up" from a state of lethargy in which it is normally found to optimize the use of the energy source and therefore extend its autonomy or useful life. For the present case, for example, a Lithium Energy Unit (BAT) (5) is used as the source, since it will offer the system a useful life that can be much longer than the useful life of the meter to which it has been interconnected. The invention has a group of counters resident in a non-volatile memory. In this group of counters, each one represents the volume consumed within a spending range. When the invention determines the time elapsed between the last two pulses, it calculates the expense and selects within a range table which volume counter must increase. With the above, a frequency "histogram" is obtained which indicates the amount of volume that has been consumed within each predetermined instantaneous expenditure interval. Concurrently, a real time clock that is an element contained in the present invention, is used to select from another group of counters the one corresponding to the period of the day in which it was detected _ * _.__ _____ .__._.-._., ._ "_. t __. *, .___ «_ ..._, .. the pulse coming from the meter. With the above, a "histogram" of time of use is obtained which indicates the frequency of the volume consumed in the different time intervals assigned to each counter of the group, previously predetermined. Because the meters can be placed on public roads, for this case, the physical installation of the invention would be performed in this same environment. Therefore, the invention provides the means to detect vandalism or fraud attempts and record them in its memory. The information stored in the memory of the invention can be accessed by a serial communication means (wired or wireless) and configured by these same means. In order to adequately illustrate the present invention, the present description of several figures is attached which are described below. Figure 1.

DETAILED DESCRIPTION The invention is shown in general form in FIGURE 1. The connection to the water meter (1) is made by means of the Meter Interface Unit (UIM) (2). All the circuitry of the invention is contained in a sealed cabinet (7) that protects it from environmental humidity, from possible dives due to flooding and unwanted human intrusion. The invention is in turn composed of a Control Unit (UDC) (3) that performs the measurements and calculations. The necessary communication for configuration, programming and reading is done through the Communication Unit (UCO) (4), with the use of a Portable Terminal or Personal Computer TP / PC (8). The invention obtains its energy from an Energy Unit (BAT) (5) connected in turn to the Energy Detection and Protection Unit (UBB) (6), in charge of monitoring the level of energy available to operate and preventing investments in the polarity of the Energy Unit (BAT) (5). The Interface to Meter Unit (UIM) (2) is shown in FIGURE 2, its function is to condition and filter the signals coming from the meter (1) coupled by means of a cable (9) to the direct line to the Unit Control (UDC) (3) (signals 10, 11 and 14). The filters pass low (15) and (16) ilÉÉáll p +. «» - **** «-« »*» - "- --- • eliminate possible noises and rebounds present in the flow signals coming from the meter The Control Unit (UDC) (3 ) shown in FIGURE 5, comprises a Microcontroller (29), which in turn contains a non-volatile memory (30) for storing parameters and a real-time clock (31) that maintains a stable time base. it is coupled to the rest of the units of the invention by means of input and output signals with respect to (29) The Communication Unit (UCO) (4) shown generally in FIGURE (4), converts the lines of communication (23) and (24) in signals that can be transmitted to an external terminal device (8), either by a wired means coupled by means of the signals (25) through the converter (26) or a wireless channel by means of the converter (27), which in turn couples the signals to and from the System through an antenna (28). Protection and Energy Detection (UBB) (6) is shown in FIGURE 3, it comprises a Shotky diode (18), which connects the Power Unit (BAT) (5) by means of the signal (17) to the signal of the power supply voltage of the invention (19) as well as a voltage detector (22), used to indicate the level of use of the Energy Unit (BAT) (5) to the Control Unit (UDC) (3) by means of the signals (20) and (21). Connection to the Meter. The invention allows the connection of diverse signals with multiple configurations. According to one of the embodiments of the present invention, the typical configuration of the signaling between a Í _ ^ __ _t_u ____?, __ __ __e_i. ___t_ meter (1) and the System of the invention, which is illustrated in FIGURE 2 by means of a cable (9) which is in turn connected to the Control Unit (UDC) (3) by means of electrical signals . By means of the signaling provided by (1) it is possible to control, through the signal (10), the presence of current in the pulse generator of (1). The pulse generator contained in (1) provides sufficient information to the Control Unit (UDC) (3) to detect a cut of the cable through the signal M_CORTE (11). The meter also generates pulses for each unit of volume that flows through the signal S_FLUJO, which is in turn filtered through the low pass filter (15) to eliminate noise that could cause false readings in (3). The filtered signal is acquired by the Control Unit (UDC) (3) through the signal M_FLOW (12). The magnetic violation detector contained in (1) is activated with the presence of an intrusive magnetic field and is coupled to the Control Unit (UDC) (3) by means of the signal C_VI0LA (14). As an additional level of security, some meters such as (1) add the means to detect the reverse flow through a reflux detector. The S_REFLUX signal is also filtered by means of (16) to generate a spurious-free signal M_REFLUX (13). The signal (13) will activate the Control Unit (UDC) (3) when the direction of water flow goes from the inside of the installation of the subscriber to the connection. Depending on the criteria of the operator, this situation may indicate a fraud or the generated information can be used to discount the ________.to. __: J »- ^. ___ > _____. ., _ .. «_ - ____ i__ .. total volume consumed by the user, the volume that has returned to the operator. The Control Unit (UDC) (3) shown in greater detail in FIGURE 5, remains in a state of lethargy that minimizes current consumption. To reduce the energy drainage of the Energy Unit (BAT) (5) in case the flow, reflow and violation detectors remain active, the signal C_CTLUIM (10) deactivates the supply voltage and introduces the Unit Control (UDC) (3) in a special mode of operation in which it monitors the signals (12, 13 and 14) until they show activity again. Acquisition and processing of data. According to this invention, it is possible to carry out the information processing to create what is identified in the present application as a "Spending Histogram" and a "Usage Time Histogram". Both entities make up two independent data structures that reside in the non-volatile memory (30) and within which there is a group of records where the limits of the expense class intervals are stored, and of time of use to the which we will call "spending interval" and "hour interval". As a characteristic of this invention, it is necessary for the operating organization to be able to program the values of the limits corresponding to the class intervals by means of (8). Each class interval of both histograms has a associated register that operates as a counter where the frequency or quantity of events that have occurred within the limits of each interval is stored. fc -.._ t_tM * __-_ uaad_, tl ___ ___ __ "_..._______ *.

For each histogram, there are n frequency counters and n class intervals that are bounded by 2 * n limits of the class intervals. The amount n will depend on the capabilities of the non-volatile memory (30) of the Microcontroller device (29) used. Also, the number of frequency counters of the two histograms may be different. For purposes of illustration of the operation of the present invention only, an example of implementation of the System in which the spending histogram will be formed by 10 spending intervals with the respective interval limits is described. The time-of-use histogram will consist of 6 time intervals with 3 frequency counters. The acquisition and processing of the data is performed when the signal (12) activates the Microcontroller (29) that is in a state of lethargy. Because concurrently the real-time clock (31) contained in (29) provides a time base, the Microcontroller (29) can measure the time difference between the pulse that has just occurred in the signal (12) and the immediate previous pulse occurred in the same signal. Since the instantaneous expenditure (Q) can be expressed as volume per unit of time (Q = V / t), and since each pulse represents a unit of known volume, the time difference between the pulses allows to infer the instantaneous step expenditure of the water by the meter. The application program that is executing within (29) analyzes the time value measured between pulses, which we will call Tq, to see which of the 10 spending intervals corresponds. The above is done by comparing if the value of Tq is within each of the 10 pairs of limits corresponding to each interval. Once the interval to which it corresponds is determined, the frequency counter associated with said interval is incremented by the application program. The frequency counters will form the histogram that will represent the subscriber's instantaneous expenditure profile where the volume that said subscriber consumes is indicated within each spending interval as well as the total of the consumed volume which can be calculated by adding the sum of the 10 counters of frequency. By means of (8), the operator can read the information of the 10 meters and process said information in their facilities so that the result of this analysis allows them to know the volume consumed by the subscriber to make the billing, to make decisions about possible compensations of error in the measurement applicable to that billing and determine the wear that the meter has suffered (1). Simultaneously with the generation of the expense histogram, the application program contained in (29) obtains the time of day that is provided by the real-time clock (31) and analyzes that value to see which of the 3 time intervals of the histogram of usage time corresponds. The above is done by comparing if the time value is within each of the 3 pairs of limits corresponding to each time interval. When determining the interval, the application program contained in (29) increments the frequency counter of usage time associated with said interval. -i _ * __._! ..-_ * __ Bfc _ »__. M.J_h ________ J___, According to figure 6, we have an illustration of the instantaneous creation of consumption histograms, in this figure the (32) represents a source of water consumption, which in this case corresponds to a bath key and (1) to a water meter, (33) identifies a graph of pulses of different duration generated by the meter (1), the (34) ), refers to an expression represented as follows: ^ = X Ithr The (35) corresponds to y_c ._? __. of% of volume against expense, having this intes determined. The consumption histogram is created when the meter (1) generates a pulse each time a certain volume of water passes through it; knowing the time elapsed between pulses, one can estimate the instantaneous expense to which said volume was consumed. The value thus calculated is compared with the limits of the predefined instantaneous expense ranges, in order to increase the totalizer associated with the corresponding range.

In the example of figure 6, we have that if X is greater than 30 but equal to or less than 60, then it means that the expense will be between the intes of 30 and 60, so as shown in graph 35 it is in this inte in which the corresponding volume consumed is added. According to figure 7, there is an example of creation of histograms of consumption schedules, as for figure 6, (32) represents a source of water consumption, which in this case corresponds to a bath key and the (1) to a water meter, (36) identifies a graph of pulses generated by the meter (1) at different times of the day, (37) corresponds to an expression that reads as _? _____? _-_ t __? itliiiiiiitriil "* - •» - "- *" »**» '- "pulse at X hours" and (38) shows a graph of% volume versus time. of consumption schedules is created when the meter (1) generates a pulse each time a certain volume of water passes through it, knowing the time of day in which it is recorded, this is compared with the limits of the predefined time ranges, to increase the totalizer associated to the corresponding range, regardless of the instantaneous expense to which it has been consumed, for example if in the previous case X is greater than 02:00 but equal to or less than 03:00 hrs, then the totalizer will increase associated with this inte, as shown in graph (38) The above action allows obtaining a histogram of time of use where the class intes represent the schedules and the frequency or value of each counter represents the volume consumed in said range schedule, in the same way as with the histogram With instantaneous expense, the 3 meters can be accessed by (8) to perform an hourly billing that allows the operator to make more efficient use of their resources by applying rates associated with each hour inte that encourage or discourage consumption in said time intes. According to another aspect of the system of the present invention, the occurrence of the signal (13) indicating an inverse flow in the meter (1) can be used to generate a histogram-like data structure, similar to that described above or increase a single accountant resident in (30) that can be read by (8) to subsequently penalize or compensate the subscriber depending on the operator's administrative policies. -Éftf? _Hfft?

Ii - ^ - ^ * a £ * "* -. & - > ~ A * - ~ -. - **> ... - ..-_.... . - > * As mentioned, whenever a pulse is present in the signals (12) and (13) the Microcontroller (29) inside the Control Unit (UDC) (3) activates and performs the processes The purpose of keeping the Microcontroller "off" (29) is to maintain a low energy consumption since the actions are performed by (29) in a very short time, keeping the average current drained from the Energy Unit (BAT) (5) at a millionth Ampere level The low power consumption is further optimized by selecting the appropriate Microcontroller (29) For the case of the present invention, it can be implemented using a PIC16LC558 from Microchip Technology, but other devices such as the MSP430-112 from Texas Instruments can be used. Most of these devices are excited with very low frequency crystals such as 32,768 Hz, which keep the operating current at very low levels and an accurate time base. Depending on the characteristics of the Microcontroller (29) used, the measurement of the elapsed time can be performed by the same Microcontroller (29) internally, constructing with code what is known as a Real Time Clock (31). The purpose of this element is to maintain concurrently a time base that allows spending measurements and maintain a clock that indicates the time of day for the hourly measurement. The implementation of the Real Time Clock (31) can be done with external electronics to (29), using components such as the Phillips PCF8583P. It is worth mentioning that the explanation of the operation of this invention has been limited only to one type of -A ___ ¿_h -_ ^ ____? _._..__ Ai _ «_, _ - *" "~ - • - * - > - - • - ^ í__ - * - ~ - »« * > - * • * application to illustrate its operation, however, the programmable nature of Microcontrollers such as (29) make the System can operate with different behaviors and adjust even in the field to the needs of the market, operator or individual organizations. Low Energy Detection The Control Unit (UDC) (3) can know the level of energy available in the Energy Unit (BAT) (5) through the Energy Protection and Detection Unit (UBB) (6) low. The circuit shown in FIGURE 3 obtains the voltage of the Power Unit (BAT) (5) present in the signal S_VBAT (17) which is in turn connected to the VCC signal (19) by means of a Shotky diode ( 18), used to protect the system from reverse polarity. The typical application voltage is 3 Volts, so a 3.6V Lithium (5) Power Unit (BAT) (5) with 2.1 Amperes-hour capacity is used. For the implementation of this invention, the amount of energy stored in the Energy Unit (BAT) (5) is sufficient to keep the entire system operating for an average time of 6 years. However, the battery can easily be replaced once it has run out. The Microcontroller (29) activates the signal C_LO B (21), placing a logical zero level each time the application program resident in the ROM decides it. The above action turns on the voltage detector (22) which internally compares the value of the VCC signal (19) with an internal reference. If the detected voltage level is less than 2. IV, the signal M_LOWB (20) will change state indicating to the Control Unit (UDC) (3) that the life of the Unit has ended.

Energy (BAT) (5). The low Power Unit (BAT) detector (5) that can be used for this invention is the Panasonic MN-13811-G 25. The actions to follow when detecting a low Energy Unit (BAT) (5) are determined in the application program, but they must include an update of a record stored in the non-volatile memory (30), within which they can be contained. other fortuitous events such as a magnetic violation detected by the signal (14), or a cut of the interconnection cable to the meter (1), by means of the signal (11). The information contained in this record can be accessed through the Communication Unit (UCO) (4). Reading and Configuration. The operator uses the Communication Unit (UCO) (4), as the means to transfer information between the invention and a Portable Terminal or Personal Computer TP / PC (8). The information is transferred by means of a secure communication protocol and can be done in a wired way, by connecting an RS-232C serial port to the connector (25), shown in FIGURE 4. The communication signals present in (25), they are adapted to a voltage level that the Control Unit (UDC) (3) can handle. The previous action is carried out by means of the converter (26), which has been implemented using a Semiconductor that can be the DS275 of Dallas Semiconductor. The integrated circuit (26) uses the available energy in the signals present in (25), to perform the conversion so that the energy required for the AA tfc - *, .-,. ^ _ I_fa-á _._.

Serial communication is taken from the Portable Terminal or Personal Computer TP / PC (8). Additionally, the communication can be made without having to make a physical contact, using a Portable Terminal or Personal Computer TP / PC (8) with an inductive transceiver. If this is the case, the communication is made by means of the antenna (28) and the signals are adapted and conditioned by means of the inductive converter (27). The wireless communication is performed by modulating the data signals with a high frequency signal, which is "coupled" to the antenna formed by a coil (28). For the present invention, a module provided by the company Fusion Meter LTD or Hexagram Inc. Can be used. Another method of communication may be to transmit the data signals via radio frequency or telephone modem. For this type of schemes, can be used integrated radio modules such as the TR1000 of the company RF Monolithics Inc., which operates in the range of 900 MHz with sufficient power levels for ranges of distance in the order of 100 meters. By any of the means of communication used, a change of state in the signal M_RXD (24) is detected by the Microcontroller (29) within the Control Unit (UDC) (3). If the Microcontroller (29) was "asleep", it will "wake up" and begin to receive the information coming from the external device. The transfer of information is governed by a password with which the validity of the access is verified; the _._-.__.____"- _,,____ TO, ".*_-__,_-_. , ___M___, ....., .... ^ .it .. ^ ...., ._, ..., JJt ^, _, ^. .._, "",, _.-, ^^, ._ _ ». * __.._-.--. previous is necessary to avoid possible fraudulent access. Once a valid access has been detected, the application program resident in the Portable Terminal or Personal Computer TP / PC (8) can access the memory of the Microcontroller (29) to read and write its contents. By means of the reading, the Portable Terminal or Personal Computer TP / PC (8) can transfer the content of the account registers or histograms that contain information about the volume that the subscriber has consumed and his profile of expenses and schedule. Similarly, the operating agency has access to information on the status of the System, this information can indicate levels of reflux, attempts of magnetic violation, cuts in the sensor cable (9) and interconnected to the meter (1). The information contained in the non-volatile memory (30), is converted to a serial format and transferred by means of the signal C_TXD (23) to the interface of the connector (25) or to the antenna (28), which can be transmitted inductive, radio frequency or any other wireless transmission method as the case may be. On the other hand, the operating organization can configure or program the operation of the invention, transferring new values to the non-volatile memory (30). The new values will govern the behavior of the resident application program in the ROM of the Microcontroller (29) and the values of the expense class and time or initialization times of the Real Time Clock (31) can be levels to name a few. The invention therefore provides a system for reading in electronic form the billing information and statistics, generated by the water meter (1) using the available means of communication. _-__ A_fc < _, __-_____-_ l - * _- * ^ ¿& _. ^. ^ .__ A.
