　登録処理部３００は、機器種別データ及び稼働状況データを機器稼働状況記録装置２から収集し、両データを関連付けて機器稼働データベース３１１に登録する。例えば、登録処理部３００は、機器稼働状況記録装置２から装置ＩＤが付与された機器種別データを受信すると、機器稼働データベース３１１に新たなレコードを追加し、その装置ＩＤと、機器種別データが示す種別（機種名及び諸元）を特定する種別ＩＤとを登録する。その後、登録処理部３００は、機器稼働状況記録装置２から装置ＩＤが付与された稼働状況データを受信すると、その装置ＩＤで登録されたレコードに対して機器稼働データを登録する。 The registration processing unit 300 collects device type data and operating status data from the device operating status recording device 2, associates both data, and registers them in the device operating database 311. For example, when the registration processing unit 300 receives the device type data to which the device ID is assigned from the device operation status recording device 2, the registration processing unit 300 adds a new record to the device operation database 311, and the device ID and the device type data indicate the record. A type ID that identifies the type (model name and specifications) is registered. After that, when the registration processing unit 300 receives the operation status data to which the device ID is assigned from the device operation status recording device 2, the registration processing unit 300 registers the device operation data in the record registered with the device ID.
　排出量算出部３０１は、機器稼働データベース３１１に種別ＩＤとして登録された機器種別データが示す種別の機器１１から排出される単位時間当たりの排出量を定める排出係数と、当該機器種別データに関連付けられて機器稼働データベース３１１に登録された稼働状況データに基づく機器稼働時間とに基づいて、記録期間における温室効果ガスの排出量を機器１１毎に算出する。 The emission amount calculation unit 301 associates an emission coefficient that determines the emission amount per unit time emitted from the device 11 of the type indicated by the device type data registered as the type ID in the device operation database 311 with the device type data. The amount of greenhouse gas emissions during the recording period is calculated for each device 11 based on the device operating time based on the operating status data registered in the device operating database 311 .
　図８は、排出量算出部３０１の一例を示す機能説明図である。以下では、図８を参照して、排出量算出部３０１が、機器稼働データベース３１１に登録された特定のレコードに基づいて、そのレコードに対応する特定の機器１１（ブルドーザ、１０ｔ）から排出された温室効果ガスの排出量を算出する場合について説明する。 FIG. 8 is a functional explanatory diagram showing an example of the emission calculation unit 301. FIG. In the following, referring to FIG. 8, based on a specific record registered in the equipment operation database 311, the discharge amount calculation unit 301 A case of calculating greenhouse gas emissions will be described.
　まず、排出量算出部３０１は、機器稼働データベース３１１の機器種別データが示す種別ＩＤをキーにして機器仕様データベース３１０を参照し、その種別ＩＤにより特定される種別の機器１１の二酸化炭素排出係数、一酸化二窒素排出係数、稼働状況判定対象センサ、及び、稼働状況判定基準値を取得する。 First, the emission amount calculation unit 301 refers to the device specification database 310 using the type ID indicated by the device type data of the device operation database 311 as a key, and calculates the carbon dioxide emission coefficient of the device 11 of the type specified by the type ID, Acquire the nitrous oxide emission coefficient, the operating status determination target sensor, and the operating status determination reference value.
　次に、排出量算出部３０１は、機器稼働データベース３１１の稼働状況データに基づいて、機器１１が稼働しているか否かを判定する稼働状況判定処理を行い、機器１１が稼働していると判定した時間を累計することで、機器稼働時間を算出する。具体的には、排出量算出部３０１は、機器稼働データベース３１１の稼働状況データのうち、稼働状況判定対象センサに対応するセンサデータ（図８の例では、加速度データ）を参照し、そのセンサデータと、稼働状況判定基準値とを比較することで、機器１１が稼働中か否かを判定する。図８の例では、加速度データが、稼働状況判定基準値を超えている場合に、排出量算出部３０１は、機器１１が稼働中と判定し、その稼働中と判定した時間を累計することで、記録期間における機器稼働時間を算出する。 Next, the emission calculation unit 301 performs operation status determination processing to determine whether or not the device 11 is operating based on the operation status data of the device operation database 311, and determines that the device 11 is operating. By accumulating the time spent, the equipment operating time is calculated. Specifically, the emissions calculation unit 301 refers to sensor data (acceleration data in the example of FIG. and the operation status determination reference value, it is determined whether or not the device 11 is in operation. In the example of FIG. 8, when the acceleration data exceeds the operation status determination reference value, the emission calculation unit 301 determines that the device 11 is in operation, and accumulates the time during which it is determined that it is in operation. , to calculate the device operating time during the recording period.
　そして、排出量算出部３０１は、二酸化炭素排出係数と、機器稼働時間とを乗算することで、記録期間における二酸化炭素の排出量を算出する。また、排出量算出部３０１は、一酸化二窒素排出係数と、機器稼働時間とを乗算することで、記録期間における一酸化二窒素の排出量を算出する。 Then, the emission amount calculation unit 301 multiplies the carbon dioxide emission coefficient by the device operating time to calculate the carbon dioxide emission amount during the recording period. In addition, the emission amount calculation unit 301 multiplies the nitrous oxide emission coefficient by the device operating time to calculate the amount of nitrous oxide emitted during the recording period.
　排出量算出部３０１は、上記のような排出量の算出処理を各レコードに対して行うことで、各機器１１の二酸化炭素の排出量及び一酸化二窒素の排出量を算出する。そして、排出量算出部３０１は、上記のように算出した機器稼働時間、二酸化炭素の排出量、及び、一酸化二窒素の排出量を、各機器１１に対応する機器稼働データベース３１１のレコードに登録する。 The emissions calculation unit 301 calculates the carbon dioxide emissions and the nitrous oxide emissions of each device 11 by performing the above emissions calculation processing on each record. Then, the emission calculation unit 301 registers the device operating time, carbon dioxide emission, and nitrous oxide emission calculated as described above in the record of the device operation database 311 corresponding to each device 11. do.
　なお、稼働状況判定処理が、機器稼働状況記録装置２の稼働状況記録部２０１により行われることで、稼働状況データに、機器１１が稼働中か否かを判定した結果が記録されている場合には、排出量算出部３０１は、稼働状況判定処理を省略し、その稼働状況データに基づいて、機器１１が稼働中と判定された時間を累計することで、機器稼働時間を算出すればよい。また、上記の稼働状況判定処理では、加速度データを用いる場合について説明したが、角速度データ、音響データ及び画像データを用いてもよいし、これらの２つ以上を組み合わせて用いてもよい。例えば、角速度データを用いる場合には、旋回時の角速度を検出することで機器１１が稼働中か否かを判定すればよいし、音響データを用いる場合には、エンジン音の大きさを検出することで機器１１が稼働中か否かを判定すればよいし、画像データを用いる場合には、例えば、周囲が撮像された画像の時間変化を検出することで機器１１が稼働中か否かを判定すればよい。 Note that the operation status determination process is performed by the operation status recording unit 201 of the device operation status recording device 2, so that when the result of determining whether or not the device 11 is in operation is recorded in the operation status data, , the emission amount calculation unit 301 may omit the operation status determination process and calculate the device operation time by accumulating the time during which the device 11 is determined to be in operation based on the operation status data. Also, in the operating status determination process described above, the case where acceleration data is used has been described, but angular velocity data, sound data, and image data may be used, or two or more of these may be used in combination. For example, when using angular velocity data, it is possible to determine whether or not the device 11 is in operation by detecting the angular velocity during turning. In the case of using image data, for example, whether or not the device 11 is in operation is determined by detecting a temporal change in an image of the surroundings. Judge.

Aggregate effect gas emissions.
　集計条件には、例えば、過去１週間や過去１か月間のように設定されたり、特定の日、週、月等のような設定されたりする集計期間と、例えば、単位期間別、機器１１の種別別、建設現場別、又は、機器１１を使用する事業者別のように設定される集計軸とが含まれる。集計条件は、例えば、管理者端末装置４に表示される集計条件設定画面４０において現場管理者１００により設定されて、管理者端末装置４が送信するレポート作成要求に含まれることで、排出量集計部３０２は、管理者端末装置４から集計条件を受信する。そして、排出量集計部３０２は、その集計条件に含まれる集計期間や集計軸に基づいて、機器稼働データベース３１１に登録された機器１１毎の温室効果ガスの排出量を参照し、例えば、集計期間に含まれる機器１１毎の排出量を集計したり、集計期間に含まれる機器毎の排出量を、単位期間別、種別別、建設現場別、又は、事業者別に集計したりする。 Aggregation conditions include, for example, an aggregation period set such as the past week or the past month, or a specific day, week, month, or the like; It also includes aggregation axes that are set by type, by construction site, or by business operator that uses the device 11 . Aggregation conditions are set by the field manager 100 on an aggregation condition setting screen 40 displayed on the administrator terminal device 4, for example, and are included in the report creation request transmitted by the administrator terminal device 4, so that emissions can be aggregated. The unit 302 receives the aggregation conditions from the administrator terminal device 4 . Then, based on the aggregation period and the aggregation axis included in the aggregation conditions, the emission amount aggregation unit 302 refers to the greenhouse gas emissions of each device 11 registered in the device operation database 311. For example, the aggregation period The emission amount of each device 11 included in the collection period is aggregated, and the emission amount of each device included in the aggregation period is aggregated by unit period, by type, by construction site, or by business operator.

　図１３は、温室効果ガスの排出量の集計及びレポートの作成に関する処理の一例を示すフローチャートである。図１３に示す処理では、主に温室効果ガス排出量算出装置３と管理者端末装置４とが連携して動作する。 (2) Aggregation of Greenhouse Gas Emissions and Creation of Report FIG. 13 is a flowchart showing an example of processing related to aggregation of greenhouse gas emissions and creation of a report. In the process shown in FIG. 13, mainly the greenhouse gas emission calculation device 3 and the administrator terminal device 4 operate in cooperation.
　まず、ステップＳ２００にて、現場管理者１００が、管理者端末装置４に表示された集計条件設定画面４０（図９参照）において集計条件を設定する集計条件設定操作を行うことで、管理者端末装置４は、集計条件の設定を受け付ける。次に、ステップＳ２０１にて、管理者端末装置４は、現場管理者１００により設定された集計条件を含むレポート作成要求を温室効果ガス排出量算出装置３に送信する。 First, in step S200, the on-site manager 100 performs a tabulation condition setting operation for setting tabulation conditions on the tabulation condition setting screen 40 (see FIG. 9) displayed on the manager terminal device 4. The device 4 accepts the setting of the aggregation conditions. Next, in step S<b>201 , the administrator terminal device 4 transmits to the greenhouse gas emission calculation device 3 a report creation request including the aggregation conditions set by the site administrator 100 .
　次に、ステップＳ２１０にて、温室効果ガス排出量算出装置３が、レポート作成要求を受信すると、排出量集計部３０２は、その受信したレポート作成要求に含まれる集計条件に基づいて、排出量算出部３０１により算出されて機器稼働データベース３１１に登録された機器１１毎の温室効果ガスの排出量を集計する。 Next, in step S210, when the greenhouse gas emission calculation device 3 receives a report creation request, the emissions totaling unit 302 calculates the emissions based on the totaling conditions included in the received report generation request. The amount of greenhouse gas emissions for each device 11 calculated by the unit 301 and registered in the device operation database 311 is aggregated.
　集計条件として、例えば、図９で示すように、集計期間が「過去１か月」と設定され、集計軸が「日別」と設定されている場合には、排出量集計部３０２は、機器稼働データベース３１１を参照し、過去１カ月間に行われた作業で使用された機器１１の稼働状況データが登録されたレコードを抽出する。そして、排出量集計部３０２は、「過去１カ月間」という集計期間により抽出された各レコードの二酸化炭素の排出量及び一酸化二窒素の排出量を日別で集計する。 As the aggregation condition, for example, as shown in FIG. 9, when the aggregation period is set to “past one month” and the aggregation axis is set to “by day”, the emissions aggregation unit 302 The operation database 311 is referred to, and records in which the operation status data of the devices 11 used in the work performed in the past month are registered are extracted. Then, the emission totaling unit 302 totalizes the carbon dioxide emission amount and the nitrous oxide emission amount of each record extracted for the totaling period of “past one month” on a daily basis.
　次に、ステップＳ２２０にて、レポート作成処理部３０３は、排出量集計部３０２により集計された集計結果に基づいてレポート情報を作成し、そのレポート情報を管理者端末装置４に送信する。 Next, in step S<b>220 , the report creation processing unit 303 creates report information based on the tallied results tallied by the emission amount tallying unit 302 and transmits the report information to the administrator terminal device 4 .
　そして、ステップＳ２３０にて、管理者端末装置４が、レポート情報を受信すると、例えば、そのレポート情報に基づく表示画面を表示する。例えば、図９に示す集計条件によりレポート情報が作成された場合には、図１０に示す第１の集計グラフ３５Ａを含む表示画面が、管理者端末装置４に表示される。上記の一連の処理において、ステップＳ２１０が排出量算出ステップ、ステップＳ２２０がレポート作成処理ステップにそれぞれ相当する。 Then, in step S230, when the administrator terminal device 4 receives the report information, it displays a display screen based on the report information, for example. For example, when the report information is created according to the aggregation conditions shown in FIG. 9, the display screen including the first aggregation graph 35A shown in FIG. 10 is displayed on the administrator terminal device 4. FIG. In the series of processes described above, step S210 corresponds to a discharge amount calculation step, and step S220 corresponds to a report creation processing step.
　以上のように、温室効果ガス排出量管理システム１によれば、機器稼働状況記録装置２が、自装置が設置される機器１１の種別を示す機器種別データと、記録開始操作から記録終了操作までの記録期間に記録された稼働状況データとを温室効果ガス排出量算出装置３に送信し、温室効果ガス排出量算出装置３が、機器種別データ及び稼働状況データを機器稼働状況記録装置２から収集して機器稼働データベース３１１に登録し、その機器稼働データベース３１１に登録された機器種別データが示す種別の機器から排出される単位時間当たりの排出量を定める排出係数と、当該機器種別データに関連付けられて機器稼働データベース３１１に登録された稼働状況データに基づく機器稼働時間とに基づいて、温室効果ガスの排出量を機器１１毎に算出する。 As described above, according to the greenhouse gas emission amount management system 1, the device operation status recording device 2 stores the device type data indicating the type of the device 11 in which the device is installed, and the data from the recording start operation to the recording end operation. to the greenhouse gas emissions calculation device 3, and the greenhouse gas emissions calculation device 3 collects the device type data and the operation status data from the device operation status recording device 2. and registered in the device operation database 311, and the emission coefficient that determines the amount of emissions per unit time emitted from the device of the type indicated by the device type data registered in the device operation database 311, and the emission coefficient that is associated with the device type data. The amount of greenhouse gas emissions for each device 11 is calculated based on the device operating time based on the operating status data registered in the device operating database 311 .
　そのため、各機器１１には、専用の測定器が取り付けられることなく、機器１１が建設現場１０で使用されるときに、汎用的な装置である機器稼働状況記録装置２が設置される。そして、機器１１に設置された機器稼働状況記録装置２が、自装置が設置された機器１１の種別を示す機器種別データと、自装置に搭載されたセンサを用いて記録した稼働状況データとを温室効果ガス排出量算出装置３に送信することで、両データが機器稼働データベース３１１に登録・収集される。 Therefore, when the equipment 11 is used at the construction site 10, the equipment operation status recording device 2, which is a general-purpose device, is installed without attaching a dedicated measuring device to each equipment 11. Then, the device operation status recording device 2 installed in the device 11 records the device type data indicating the type of the device 11 in which the device is installed and the operation status data recorded using the sensor installed in the device. Both data are registered/collected in the equipment operation database 311 by transmitting them to the greenhouse gas emission calculation device 3 .
　そして、機器稼働データベース３１１に登録・収集された機器種別データ及び機器稼働データが、温室効果ガス排出量算出装置３により参照されて、機器種別データに基づく機器１１の種別に応じた排出係数と、稼働状況データに基づく機器稼働時間とに基づいて、機器毎の排出量が算出される。したがって、建設現場１０で使用される機器１１から排出される温室効果ガスの排出量を算出する際の簡便性及び正確性を向上させることができる。 Then, the device type data and the device operation data registered and collected in the device operation database 311 are referred to by the greenhouse gas emission calculation device 3, and the emission coefficient corresponding to the type of the device 11 based on the device type data, The emission amount for each device is calculated based on the device operating time based on the operating status data. Therefore, it is possible to improve the simplicity and accuracy of calculating the greenhouse gas emissions from the equipment 11 used at the construction site 10 .
　さらに、機器毎の排出量が、温室効果ガス排出量算出装置３により所定の集計条件（集計期間や集計軸）に従って集計されるので、温室効果ガスの排出量に関するレポートを作成する際の簡便性及び正確性を向上させることができる。 Furthermore, the greenhouse gas emission calculation device 3 aggregates the emissions of each device according to predetermined aggregation conditions (aggregation period and aggregation axis), so it is easy to create a report on the amount of greenhouse gas emissions. and accuracy can be improved.
