Description

  TECHNICAL FIELD The present invention relates to a gas piping airtightness / leakage inspection data authenticity determination method and an airtightness / leakage inspection report, and in particular, relates to the gas piping volume specific to each dwelling unit with the amount of gas leakage, and the airtightness / leakage inspection of the gas piping. The present invention relates to a gas pipe airtightness / leakage inspection data authenticity judgment method and an airtightness / leakage inspection report which enable verification of the authenticity of measured value data in Japan

  Conventionally, after construction of a gas pipe in a newly-built dwelling unit or the like, an airtightness / leakage inspection of the gas pipe is performed to confirm that there is no abnormality such as a gas leak. The gas pipe airtightness / leakage inspection is carried out regularly or voluntarily according to the law. In general, gas companies entrust the gas pipe airtightness / leakage inspection work to companies such as external gas construction companies. Often to do. The contracted company conducts gas pipe airtightness / leakage inspection at the site and reports the measured value data in the airtightness / leakage inspection report to the gas company. In this case, there was no reliable guarantee that the reported measurement data was genuine data actually measured at the dwelling unit by an inspector of the contracted company, and there was no way to prove it.

  In order to prove the reliability of the data of the airtightness / leakage inspection, obtain the specific information of the dwelling unit that actually performed the airtightness / leakage inspection of the gas pipe, and associate the specific information with the data of the airtightness / leakage inspection. It is possible to authenticate. For example, as shown in FIG. 3, an authentication method is conceivable in which position information by GPS (Global Positioning System) 1 and a leak inspection function by pipe airtightness / leakage inspection device 2 are combined.

In this GPS authentication method, the position information of each dwelling unit is measured by the GPS 1 and the gas tightness / leakage inspection (gas leakage test) of the gas piping of each dwelling unit is performed by the pipe airtightness / leakage inspection device (gas leakage inspection device) 2. Then, the printer 3 prints the gas leakage amount data obtained by the pipe airtightness / leakage inspection device 2 and the position information data obtained by the GPS 1. Next, submit this printed matter to the gas company as an airtight / leakage inspection report 4 and verify that the data is not counterfeited or falsified, and authenticate the authenticity of the data (for example, similar related technology). As an example, refer to Patent Document 1).
JP 2004-85239 A.

  In the GPS authentication method, each dwelling unit is close to each other in an apartment unit such as an apartment. Therefore, it is difficult to accurately discriminate each dwelling unit with the position determination accuracy of each dwelling unit using GPS. In addition, since the GPS radio wave does not reach sufficiently in the house, the unique information of each dwelling unit cannot be obtained accurately by GPS. Therefore, many difficulties are involved in putting the GPS authentication method into practical use as a means for certifying the reliability of the airtight / leakage inspection data.

  An authentication method using information such as a barcode unique to each dwelling unit is also conceivable. As shown in FIG. 4, the unique information of each dwelling unit, for example, the bar code information affixed to the gas meter 5 in each dwelling unit is scanned with the bar code reader 6, and the gas tightness / leakage inspection device 2 Airtightness / leakage inspection is carried out, and the gas leakage amount data and the unique barcode data obtained at this time are printed by the printer 7 and, similarly to the above, this is reported to the gas company as an airtightness / leakage inspection report 8. Submit and authenticate the authenticity of the data.

  According to this barcode authentication method, when building a building such as an apartment, for example, before a gas meter is installed in each dwelling unit, it is not determined whether or not the barcode itself is arranged in each dwelling unit. The bar code cannot be used as a means for authenticating the measured value data in each dwelling unit. In this case, since it is possible to read a barcode without actually going to each dwelling unit, there is a risk that the measured value data may be forged or falsified by a Service-to-Self. Therefore, the bar code authentication method cannot prevent data fraud, and the reliability of the measured value data of the pipe airtightness / leakage inspection is lowered.

  Therefore, the authenticity of the airtightness / leakage inspection data in the gas piping of each dwelling unit can be reliably verified, and the reliability of the data can be improved by preventing forgery / falsification of the airtightness / leakage inspection data (measurement value data). Therefore, a technical problem to be solved arises, and the present invention aims to solve this problem.

The invention according to claim 1 is a method for measuring the volume and gas leakage amount of a gas pipe of a dwelling unit with a pipe airtightness / leakage inspection instrument, and determining the authenticity by describing the measured value data in an airtightness / leakage inspection report. Adopting the volume of the gas pipe of the dwelling unit as unique identification data that becomes a comparison reference when determining the authenticity of the measured value data, and encrypting the volume of the gas pipe into code data such as alphabets; The encrypted code data is described in the airtightness / leakage inspection report together with the measured value data, and the volume of the gas pipe of the dwelling unit is again determined by the airtightness / leakage inspection device at the time of data authenticity determination. a step of measuring a container product measured value data, and compares and collates the volumetric value data described in the hermetic-leakage inspection report, when the integrity of both the data is confirmed only, before Providing a step to verify the authenticity of the measurement value data, a gas pipe airtight spilled inspection data authenticity determination method, characterized in that it comprises a.

According to this configuration, the volume of the gas pipe of the dwelling unit and the amount of gas leakage are measured with a pipe airtightness / leakage inspection device, and when determining the authenticity of this measured value data, Adopt the volume of gas piping. First, an inspector of the contracted company visits the site and measures the volume of gas piping and the amount of gas leakage in each dwelling unit with a pipe airtightness / leakage inspection device. Encrypt. The encrypted code data is described in the airtightness / leakage inspection report together with the measured value data indicating the volume of the gas pipe and the gas leakage amount.

Thereafter, the volume of the gas pipe of the dwelling unit is again measured with a pipe airtightness / leakage inspection device, and the volumetric measurement value data is compared with the volumetric measurement value data described in the airtightness / leakage inspection report . As a result, only when the predetermined consistency is confirmed, the authenticity of the measured value data is proved. When the predetermined consistency is not confirmed, the authenticity certification of the measured value data is rejected.

The invention described in claim 2 is a gas tightness / leakage inspection report in which measurement data obtained by measuring the volume of the gas pipe of the dwelling unit and the amount of gas leakage with a pipe airtightness / leakage tester is described. The leakage inspection report is used for the gas pipe airtightness / leakage inspection data authenticity determination method according to claim 1 , and has an area where measurement value data and pipe identification data are described. the described area is described numerical value indicating the volume and the gas leakage amount of the measured gas pipe during gas pipe hermetically-leakage inspection of dwelling is and the the description area of the pipe identification data, the volume of the gas pipe configured such that the code data of alphabetic or the like encryption is described, the measurement value measured value of the volume of the gas piping of dwelling units obtained by re-measured by a pipe hermetically-leak tester during authentication judgment data Providing a chromatography data, and compares and collates the volumetric value data described in the described areas, a hermetic-leakage inspection report to feature that it has to be able to confirm the success or failure of integrity of both data .

According to this configuration, the airtightness / leakage inspection report includes a numerical value indicating the volume of the gas pipe of the dwelling unit and the amount of gas leakage measured by a contracted inspector, and an alphabet or the like that encrypts the volume of the gas pipe. The code is described. Then, the measured value data of the volume of the gas pipe of the dwelling unit measured again by the pipe airtightness / leakage detector at the time of authenticity determination of the measured value data is compared with the volume measured value data described in the above described area. The success or failure of the consistency of both data is confirmed. The volume of the gas pipe is pipe identification data unique to each dwelling unit, and measurement value data is associated with the pipe identification data. Therefore, it is virtually impossible to forge or falsify the measured value data due to malicious intent.

In the invention described in claim 1, since the inspector of the contracted company does not actually go to the dwelling unit and perform the airtightness / leakage inspection, it is not possible to obtain the data of the piping volume of each dwelling unit. It is virtually impossible to forge and use the inspection data collected at the site, and it is possible to secure a higher authentication function than in the past.

The invention according to claim 1 adopts the volume of the gas pipe of the dwelling unit as the unique identification data as a comparison reference when determining the authenticity of the measured value data, and the encrypted code data is the data of the gas pipe. It is described in the airtightness / leakage inspection report together with the measurement value data indicating the volume and the amount of gas leakage, and after that, the volume of the gas pipe of the dwelling unit is again measured with a pipe airtightness / leakage inspection instrument, The authenticity of the measured value data is proved only when a predetermined consistency is confirmed as a result of comparing and comparing the volume measured value data. Therefore, since the gas pipe is encrypted as pipe identification data, the authenticity of the measured value data is authenticated by associating it with the measured value data, so that fraudulent acts such as data fabrication by the Service-to-Self can be prevented in advance. Thus, the volume of the gas pipe, which is the pipe identification data, is encrypted and cannot be understood by anyone other than a specific party, so there is almost no risk that the volume data of the pipe itself is forged or altered.

In the second aspect of the invention, the gas tightness / leakage inspection report describes the volume of the gas pipe or a code such as an alphabet in which the volume of the gas pipe is encrypted and the measured value data. The measured value data of the volume of the gas pipe of the dwelling unit measured again by the pipe airtightness / leakage inspection device is compared with the volume measurement value data described in the above described area, and the success or failure of the consistency of both data is confirmed. can see, only to report procedure normally airtight, loss inspection, the data can be prevented fraud, in this case, the input device or the reading device such as an expensive bar code is not required, simple and inexpensive commercialization It has a merit that can be.

The present invention makes it possible to easily and reliably determine the authenticity of the measured value data of the airtightness / leakage inspection by the inspector in the gas piping of the dwelling unit, and to prevent the counterfeiting / tampering of the measured value data, thereby ensuring the reliability of the measured value data. In the method of determining the authenticity by measuring the volume of the gas pipe of the dwelling unit and the amount of gas leakage with a pipe airtightness / leakage inspection device, and describing the measured value data in the airtightness / leakage inspection report, Adopting the volume of the gas pipe of the dwelling unit as unique identification data that becomes a comparison reference when determining the authenticity of the measurement value data, and encrypting the volume of the gas pipe into code data such as alphabets; the dark Goka code data, the steps described in the hermetic-leakage inspection report together with the measurement data, piping gas volume of the gas pipe of the dwelling during the data authentication judgment - a step of re-measured by the leakage tester, a container product measured value data, and compares and collates the volumetric value data described in the hermetic-leakage inspection report, when the integrity of both the data is confirmed And a step of proving authenticity of the measured value data, and realizing the authenticity determination method for gas piping airtightness / leakage inspection data.

  Hereinafter, a preferred embodiment of the present invention will be described. In the present embodiment, by using a pipe airtightness / leakage tester having a built-in pump, pressure gauge, etc., the gas pipe volume of each dwelling unit (hereinafter referred to as the pipe volume) and pressure drop in a known inspection procedure. The value can be measured.

  Usually, the pipe volume is used for the purpose of calculating the amount of gas leakage, but the pipe volume in each dwelling unit is different even if the floor plan is the same, so this pipe volume is used as identification data unique to each dwelling unit. It can be used as a “fingerprint”. That is, by associating the pipe volume with the inspection data of the gas leakage amount, it is possible to prevent forgery / falsification of data by the Service-to-Self.

  The pipe volume is a data value measured by a pipe airtightness / leakage tester. For this reason, it is difficult to avoid mixing errors due to data measurement, but the pipe volume data can be effectively used as reproducible information values by stopping within the range of significant figures that are sufficiently reproducible. .

  FIG. 1 shows a data authenticity determination system according to this embodiment. In the figure, 11 is a pipe gas tightness / leakage tester for propane gas (for example, trade name “Saberpro”, sold by AIMTEC Co., Ltd.). The pipe airtightness / leakage tester 11 includes a pump, a pressure gauge, etc. Is built-in. By using the pump, pressure gauge, etc., for example, when performing gas tightness / leakage inspection after gas piping work for a newly built unit, the piping volume and pressure drop value (gas leakage amount data) on the downstream side of the gas meter of the unit ) Can be measured with high accuracy.

  The data authenticity determination system of the present invention checks the authenticity of inspection data by associating pipe identification data unique to each dwelling unit with actual inspection data. In this embodiment, first, an inspector of the contracted company goes to each dwelling unit and measures the pipe volume and the pressure drop value of each dwelling unit using the pipe airtightness / leakage inspection device 11. Then, the measurement value and the inspection date are encrypted into codes such as alphabets according to a predetermined conversion rule. Next, the encrypted code data and the measured data of the pipe volume and the pressure drop value are printed on the airtight / leakage inspection report 13 for the dwelling unit by the printer 12.

  In this case, the airtightness / leakage inspection report 13 includes the measured value data description area in which numbers indicating the volume and pressure drop value (gas leak amount) of the gas pipes of each dwelling unit, and the pipe volume and pressure drop value are described. And the pipe identification data description area in which the alphabet that encrypted the inspection date is described, the measured value data of the pipe volume and the pressure drop value, and the encrypted code data are respectively described above. Display in the area.

  Then, when it becomes necessary to determine the authenticity of the measured value data, the volume of the gas pipe and the amount of gas leakage of the dwelling unit are accurately measured again. Next, the authenticity of the measured value data is determined by comparing the measured value data with the first measured value data.

  FIG. 2 shows a procedure for encrypting specific measurement value data. First, airtightness / leakage inspection is performed at each dwelling unit, and the pipe volume and pressure drop value are measured. As illustrated in the inspection-related information table 14 in the figure, it is assumed that, for example, a pipe volume of 12.76 liters and a pressure drop of 0.04 kPa are measured on January 29, 2005. At this time, the seven-digit number “2005129” is used as it is for the date, but the upper three digits of the measured value are used as significant figures. That is, the value of the pipe volume uses “127”, and the value of the pressure drop uses “004”. In this embodiment, it is possible to prevent the user from falsifying the airtightness / leakage inspection report by configuring so that the user cannot change the date information.

  Next, significant digits of date, pipe volume and pressure drop value are combined in this order to obtain a 13-digit number “2005129127004”. Thus, the 13-digit number is converted into alphabets for encryption processing. In this case, the encryption processing is performed according to the conversion rules of the substitution conversion table 15 in the illustrated example. In the conversion rule of the substitution conversion table 15, numbers “0” to “9” correspond to alphabets “Z” to “V” as shown in the figure. Therefore, the number “2005129127004” is encrypted to the alphabet “SZZCTSVTEZZQ”.

  The encrypted alphabet is printed in a lower margin of the data output form (airtight / leakage inspection report) 16 as shown in FIG. Accordingly, by examining the consistency between the measured value data entered in the data output form 16 and the encrypted alphabet data, it is easily determined whether or not the measured value data is regular data. .

  Note that the encryption processing method used in the illustrated example is a simple substitution conversion method, but other more advanced encryption processing methods can also be used.

  According to the present embodiment, the inspector of the contract company visits the site to measure the piping volume and pressure drop value of each dwelling unit, and encrypts the measured value and the 13-digit number of the inspection date into alphabetic codes. . This encrypted code and the 13-digit number are written in a predetermined location of the airtightness / leakage inspection report.

  Then, only when it is necessary to determine the authenticity of the measurement value data, the pipe volume of the dwelling unit is measured again, and the volume measurement value data and the volume measurement value data are compared and collated. As a result, it is determined that the measured value data is “genuine” only when predetermined consistency is confirmed.

  As described above, according to the present invention, the pipe volume is encrypted as pipe identification data and authenticated in association with actual measurement value data. Therefore, it is possible to reliably prevent forgery and falsification of data by a Service-to-Self.

  In addition, since the pipe volume is encrypted in alphabets, only the person who is obliged to keep secret can grasp the data contents. Therefore, there is no fear that the pipe volume data itself is forged.

  Furthermore, the piping volume data of each dwelling unit cannot be acquired unless the inspector actually goes to the site and inspects. Therefore, it is virtually impossible to forge and substitute inspection data collected at other sites, and a high authentication function is always secured.

  Furthermore, only the encrypted data and the measured value data are described in the airtightness / leakage inspection report, and authentication can be automatically performed simply by following the conventional airtightness / leakage inspection report procedure. Therefore, no special means such as an expensive bar code input device and reading device is required, and it can be put into practical use simply and at low cost.

  In addition, it can replace with the encryption method of this invention and can also ask | require the authenticity check of an airtight test only by printing a piping volume and the amount of gas leaks simultaneously.

  The present invention can be variously modified without departing from the spirit of the present invention, and the present invention naturally extends to the modified ones.
