Description

  The present invention relates to a measuring instrument that measures the supply amount of supplies such as electricity, gas, and water supplied from the supply side of a power company, a gas company, a water bureau, etc. to a demand side, and measurement by this measuring instrument. The present invention relates to a method for determining whether or not there is a fraud in a reported value when a value is reported from a demand side to a supply side.

  Usually, electric power is supplied to a demand side such as a general household or a corporation by an electric power company through an electric wire. On the demand side, each has a power meter, and the power consumption is displayed cumulatively by this power meter. The accumulated power consumption amount is metered regularly (for example, every month) by a meter reader of an electric power company, and the amount of power consumed in a predetermined period is calculated. And the electric power company collects the electric power charge from the demand side according to the amount of power consumption.

  The same applies to gas and water. Gas companies and water departments supply gas and water to the demand side through gas pipes and water pipes, and meter readers regularly read gas meters and water meters. Thus, the amount of gas and water consumption consumed for a predetermined period are converted into gas charges and water charges, and these charges are collected from the demand side.

However, if the demand side is in a mountainous area or a remote island where the transportation is not convenient and it is not easy for the meter reader to access, the customer himself / herself performs the meter reading work, and the result of the meter reading is contacted by telephone. Or, you can have your self-reported by mailing the completed form.

  However, such a self-reporting meter reading method has a problem that a so-called fraudulent report that a customer intentionally reports a low meter reading result may be easily made.

  For this reason, for example, once a year, or once for 10 self-reports, although it is rarer than the usual case, an illegal report is also made by the meter reader visiting the actual site and reading the meter. It is necessary to take measures to prevent this.

  However, it is self-evident that the reading of the meter in a place with poor traffic not only places a great burden on the meter but also increases the cost of meter reading.

  In order to solve this problem, power meters, gas meters, and water meters, which are measuring instruments, are connected to a communication infrastructure, and meter reading data is transmitted to the supply side such as the power company, gas company, and water station through this communication infrastructure. It is possible to do. Patent Document 1 discloses a technique for connecting a measuring instrument to a communication infrastructure and transmitting measurement data to the supply side via the communication infrastructure.

  If this technology is used and meter reading data is sent from the measuring instrument to the supply side via the communication infrastructure, the meter reading operation is automatically performed, so that not only the meter reader is unnecessary. Further, the reliability of meter reading data can be improved.

  However, providing a new communication infrastructure in the mountains or in places such as remote islands has the problem of enormous costs.

  The present invention has been made in view of such circumstances. By having the meter-reading data reported from the demand side to the supply side, the cost required for meter-reading is reduced and the meter-report data is illegally reported. It is an object of the present invention to provide a fraud determination method capable of preventing the fraud and a measuring instrument to which the fraud determination method is applied.

  In order to achieve the above object, the present invention takes the following measures.

  That is, in the invention of claim 1, the supply amount of the supply supplied from the supply side to the demand side is a value notified to the supply side from the demand side provided with a measuring instrument for measuring the supply amount. This is a method for determining the presence or absence of fraud, and the measuring instrument performs a calculation according to a predetermined calculation method using the supply amount, and generates notification data using the calculation result and the supply amount. indicate. On the demand side, the displayed notification data is notified to the supply side. On the supply side, a first solution corresponding to the calculation result and a second solution corresponding to the supply amount are obtained by performing a reverse operation of a predetermined calculation method on the notified data for notification. When the calculation is performed according to a predetermined calculation method using the second solution, and the calculation result matches the first solution, the notified data for notification is not illegal. If it does not match, it is determined that there is fraud.

  Therefore, in the fraud determination method of the invention of claim 1, by taking the above-described means, when the calculation result as described above and the first solution do not match, the declared supply amount is It is possible to easily determine that the value is not correct, that is, an illegal report has been made.

  In the invention of claim 2, in the method of the invention of claim 1, on the demand side, the displayed notification data is input to a mobile terminal having a communication function, and the notification data input to the mobile terminal is Notification is performed by transmitting to the supply side using the communication function of the mobile terminal.

  Therefore, in the fraud determination method according to the second aspect of the present invention, the notification data can be transmitted to the supply side without providing a new communication infrastructure by taking the above-described means.

  A third aspect of the invention is the method of the first or second aspect of the invention, wherein the mobile terminal is a mobile phone.

  Therefore, in the fraud determination method of the invention of claim 3, since a widely used mobile phone can be used for the transmission of the notification data, the newly generated cost can be minimized and the meter reading can be performed. It is possible to rationalize the work.

  The invention of claim 4 is a measuring instrument for measuring the supply amount of the supply supplied from the supply side to the demand side, and this measuring instrument is predetermined by the supply side using the supply amount. Calculation means for performing calculation according to the calculation method, generation means for generating notification data, which is data for notifying the supply side of the supply amount, using the calculation result and supply amount by the calculation means, and generation means Display means for displaying the notification data generated by.

  Therefore, in the measuring instrument according to the fourth aspect of the present invention, notification data subjected to a certain type of scramble can be generated by performing the above-described calculation using the measured supply amount. This makes it difficult to understand what this notification data means, so even if a customer intentionally performs unauthorized rewriting that would result in a lower supply amount, the intended rewriting cannot be performed. . Also, in the unlikely event that the notification data is rewritten, it is possible to determine fraud because a contradictory result is obtained by performing a reverse operation on the notification data on the supply side. Become.

  According to the present invention, a fraud determination method capable of reducing the cost required for meter reading and preventing illegal reporting of meter-reading data by having the meter-reading data reported from the demand side to the supply side. And a measuring instrument to which this fraud determination method is applied can be realized.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  The fraud determination method according to the embodiment of the present invention is a method for determining whether or not the value declared from the demand side is fraudulent with respect to the supply amount of the supply supplied from the supply side to the demand side. FIG. 1 is a functional block diagram showing a configuration example of a measuring instrument to which such a fraud determination method is applied.

  That is, the measuring instrument 10 is a device that measures the supply amount of the supply supplied from the supply side to the demand side, for example, from a gas meter or electric power company that measures the amount of gas supplied from the gas company. A power meter that measures the amount of power supplied, a water meter that measures the amount of water supplied from the Waterworks Bureau, and the like are applicable.

  The measuring instrument 10 includes a flow rate sensor 12, a central control unit 14, a memory 15, a calculation unit 16, a time management unit 17, and a data display unit 18.

  The flow rate sensor 12 measures the flow rate of the supply supplied from the supply side to the demand side, and outputs a flow rate signal corresponding to the measurement result to the central control unit 14.

  The central control unit 14 grasps the supply amount of the supplied supply based on the flow rate signal output from the flow sensor 12 and writes the supply amount data in the memory 15.

  In the time management unit 17, the timing at which the weighing instrument 10 accumulates the weighing data is set in advance. Then, at this timing (for example, the last day of every month), an integration request signal is input to the central control unit 14. This integration request signal includes the date and time when the integration starts and the date and time when the integration ends.

  When the integration request signal is input from the time management unit 17, the central control unit 14 supplies the supply amount data written in the memory 15 during the period between the integration start date and time and the integration end date and time included in the integration request signal. Is output to the arithmetic unit 16.

  Then, the calculation unit 16 obtains an integrated supply amount in the period by integrating all the output supply amount data, and performs an operation based on the integrated supply amount and a predetermined calculation method. Further, report notification data is created using the calculation result and the integrated supply amount, and is written into the memory 15 via the central control unit 14.

A specific example of creating such report notification data will be described. For example, when the measuring instrument 10 is a gas meter, the cumulative supply amount of gas in the period is 45.32 m ³ , and the date is April 30, the calculation for adding 04.30 to 45.32 is performed. And 49.62 is obtained as the calculation result. Furthermore, the report notification data 4495322 is generated by alternately connecting numbers 4962 obtained by multiplying the calculation result 49.62 by 100 and 4532 obtained by multiplying the integrated supply amount 45.32 by 100 one by one. Of course, the calculation method for creating the notification notification needle data is not limited to the above.

  When the report notification data created in this way is written in the memory 15, the central control unit 14 causes the data display unit 18 to display the report notification data together with the integrated supply amount.

  If the report notification data is displayed from the data display unit 18 in this way, the demand side notifies the supply side of the report notification data together with the integrated supply amount. As a method of notification, the numerical value of the data for notification of notification may be read from the data display unit 18 and the read numerical value may be communicated by telephone, or the information entered on a predetermined entry form is notified by mail. Also good. Alternatively, the method is not particularly limited, such as transmission as electronic data from a personal computer or a portable terminal via electronic mail or the Internet, or transmission as data from a cellular phone or a fixed phone.

When the report notification data is notified to the supply side, the supply side performs reverse calculation of the calculation method performed by the calculation unit 16 on the notified notification notification data. That is, when 4946622 is notified as the report notification data, 4962 and 4532 are obtained from the report notification data 4495622, and by multiplying each by 1/100, two solutions, that is 49.62, are obtained. , 45.32. Since the date is April 30, 45.32 is obtained by subtracting 04.30 from the former solution 49.62. By confirming that this value matches the latter solution, it is determined that there is no fraud in the report notification data, and the correct integrated supply amount 45.32 m ³ can be grasped. If they do not match, it is determined that there is a fraud or that an incorrect numerical value has been notified.

  As described above, in the measuring instrument 10 to which the fraud determination method according to the embodiment of the present invention is applied, by declaring the notification notification data from the demand side to the supply side, Meter reading can be performed without the need. As a declaration method, since it can be done by existing means using telephone contact, mail, electronic mail, the Internet, etc., it is not necessary to take new communication infrastructure and equipment correspondence, and it will bring about cost increase Absent.

  Further, the data to be reported from the data display unit 18 to the demand side is obtained by performing a predetermined calculation on the numerical value to be reported from the demand side to the supply side together with the integrated supply amount and applying a certain scramble. Is displayed. The displayed notification data is not related to the numerical value to be reported at first glance, so in the unlikely event that the demand side tries to rewrite it to a lower value for fraudulent reporting. However, there is no way of knowing how to rewrite, and unauthorized rewriting can be prevented.

  In the unlikely event that rewriting is performed, the supply side that has received the report notification data performs a reverse operation of the operation performed by the operation unit 16 and finds that there is a contradiction in the result. Be grasped. In addition, although there was no intention to rewrite, even if the wrong notification data was notified to the supplier due to a mistake in reading or writing, a contradiction in the results was found by the above reverse operation, It can be easily grasped that the accumulated supply amount.

  In this way, when the incorrect notification notification data is notified, the supply side requests the demand side to notify the notification notification data again. As a result, the correct report notification data is finally notified to the supply side, so that correct meter reading data (in this case, integrated supply amount) can always be collected.

  As described above, according to the embodiment, by having the customer himself / herself report the meter reading data on the supply side, the cost required for meter reading can be reduced and fraudulent reporting of meter reading data can be prevented. It is also possible to do.

  The best mode for carrying out the present invention has been described above with reference to the accompanying drawings, but the present invention is not limited to such a configuration. Within the scope of the invented technical idea of the scope of claims, a person skilled in the art can conceive of various changes and modifications. The technical scope of the present invention is also applicable to these changes and modifications. It is understood that it belongs to.
