Description

点検管理装置、点検管理方法及び点検管理プログラムInspection management device, inspection management method and inspection management program
　本開示は、主に屋外に配置されている設備の点検を行うための装置及び方法に関する。 The present disclosure relates mainly to an apparatus and method for inspecting equipment located outdoors.
　屋外に設備を設置して、サービスを提供している会社は多くある。例えば、高速道路を管理する高速道路公団、そして、電気を送る電力会社、お客様を送るための鉄道サービスを提供している鉄道会社、電話を提供している電話会社と、多くの企業が、屋外に設備を構築して、ユーザにサービスを提供している。 There are many companies that install equipment outdoors and provide services. For example, the expressway public corporation that manages expressways, electric power companies that send electricity, railroad companies that provide railroad services for sending customers, telephone companies that provide telephones, and many other companies We provide services to users by building facilities in
　屋外に設備を構築すると必ず定期点検が生じる。屋外設備のほとんどは、金属、コンクリート、プラスチック等で構成されており、屋外に設置することで、紫外線による劣化や、雨及び風による劣化が生じており、設置年数が長くなると劣化が進行する。そこで、日々の定期点検、定期メンテナンスが必要になり、その基本は作業員による目視確認である。 　Constructing equipment outdoors will inevitably require regular inspections. Most outdoor facilities are made of metal, concrete, plastic, etc. When installed outdoors, they are subject to deterioration due to ultraviolet rays, rain, and wind. Therefore, daily periodic inspections and periodic maintenance are required, and the basis thereof is visual confirmation by workers.
　しかし、日本国の人口が減っており、特に労働人口が減っている。そうなると、点検をするための作業員の人数も減っていく。一方で、全国に構築された設備量は莫大であり、例えば、電柱は通信、交通、鉄道を含めると３０００万本と言われている。その屋外に設置された設備の劣化具合を目視確認したくても、作業員が不足しているため、点検ができない可能性がある。そこで、点検を効率的にするために様々な技術が開発されている。 However, Japan's population is declining, especially the working population. As a result, the number of workers required to perform inspections will also decrease. On the other hand, the amount of facilities built all over the country is enormous. For example, it is said that there are 30 million telephone poles including communication, transportation, and railroads. Even if you want to visually check the degree of deterioration of the equipment installed outdoors, there is a possibility that inspection cannot be performed due to a shortage of workers. Therefore, various techniques have been developed to make inspections more efficient.
　屋外に設置された構造物を効率的に点検するために、ドローンが挙げられる。ドローンとは小型の飛行物体であり、その飛行物体にカメラを取り付けた効率的な作業としている。 Drones can be used to efficiently inspect structures installed outdoors. A drone is a small flying object, and a camera is attached to the flying object for efficient work.
　このドローンをその会社に所属する社員が飛ばし、点検をしたい構造物、例えば、高速道路の橋げた、電力会社の鉄塔、電話会社の電柱をターゲットとして、その構造物にドローンを近づける。そのドローンにはカメラが備わっており、そのカメラが、例えば、ひび割れ、傾き、コンクリートの剥離などの劣化状況の写真を撮る。作業者は、その写真から劣化判定をしている。（例えば、非特許文献１参照。） An employee belonging to the company flies this drone and targets a structure to be inspected, such as a highway bridge girder, a power company's steel tower, or a telephone company's pole, and brings the drone closer to the structure. The drone is equipped with a camera that takes pictures of deterioration, such as cracks, tilts, and flaking concrete. The worker judges deterioration from the photograph. (For example, see Non-Patent Document 1.)
　上記の方法は、ドローンを飛ばせる技術者が必要であり、ドローンを飛ばすための免許書が必要である。さらに、劣化した構造物の写真を取って、その場で判断ができることである。これをするためには、それなりの経験が必要であり、その会社が社員を教育しなければならない。 The above method requires a technician who can fly the drone, and a license to fly the drone. Furthermore, it is possible to take pictures of deteriorated structures and make judgments on the spot. In order to do this, a certain amount of experience is required, and the company must educate its employees.
　背景にも述べたが、作業員の人数が減っていく今後のことを考えると、今までと同じ従業員での点検方法を継続することは困難と予想される。 As mentioned in the background, considering that the number of workers will decrease in the future, it is expected that it will be difficult to continue the inspection method with the same employees as before.
　そこで、本開示は、専門の点検者を用いることなく、長期間に亘って安定的な設備点検を行うことを可能にすることを目的とする。 Therefore, the present disclosure aims to enable stable equipment inspection over a long period of time without using a professional inspector.
　発明者らは、技術を持たない人材、かつ、その会社にも所属していない人材に協力してもらうことで、従来どおりに点検ができる発明を考案した。 The inventors devised an invention that allows inspections to be performed as before, with the cooperation of people who do not have the skills and who do not belong to the company.
　本開示の点検管理装置及び点検管理方法は、
　点検対象設備とその撮影方法を含む点検指令を生成し、
　点検指令を点検指令に応じた設備状態取得装置ごとに送信し、
　点検対象設備の撮影された点検画像を各設備状態取得装置から受信し、
　受信した前記点検画像を同一の点検対象設備の撮像された他の画像と比較することで、前記点検画像の整合性を判定し、
　整合性がある場合、前記点検画像を点検結果として記録し、前記点検画像の送信元の設備状態取得装置の評価を高くし、
　整合性がない場合、前記点検画像を点検結果から除外し、前記点検画像の送信元の設備状態取得装置の評価を低くする。 The inspection management device and inspection management method of the present disclosure are
Generating an inspection command that includes the equipment to be inspected and its shooting method,

（本開示を実施するための第一形態）
　図１に、本開示に係るシステム構成の概略を示す。本開示に係るシステムでは、電柱やマンホール等、公の場所に設置されている点検対象設備に対して、設備状態取得装置２０を持った点検者Ａや点検者Ｂが、点検管理装置１０から設備状態取得装置２０を経由して受け取った点検指令に従って点検を実施するものである。設備状態取得装置２０は、通信、写真撮影、位置情報取得などの機能を有する任意の装置を用いることができ、例えば携帯電話等の端末でありうる。また点検者Ａや点検者Ｂは点検対象設備を保有者ではなく、点検に関する技術保有の有無は問わない。 (First form for carrying out the present disclosure)
FIG. 1 shows an outline of the system configuration according to the present disclosure. In the system according to the present disclosure, an inspector A or an inspector B, who has the equipment status acquisition device 20, can inspect equipment installed in public places, such as utility poles and manholes, from the inspection management device 10. Inspection is performed according to the inspection command received via the state acquisition device 20 . The facility status acquisition device 20 can be any device having functions such as communication, photography, and location information acquisition, and can be a terminal such as a mobile phone, for example. Also, the inspector A and the inspector B are not the owners of the equipment to be inspected, and it does not matter whether they possess the technology related to the inspection.
　図２は、点検管理装置１０及び設備状態取得装置２０の機能ブロック図を示す。点検管理装置１０は、点検結果受信部１１、点検写真整合性判定部１２、評価変動値付与部１３、点検結果ＤＢ１４、点検設備ＤＢ１５、点検指令生成部１６を備える。設備状態取得装置２０は、点検指令受信部２１、点検指令表示部２２、点検写真取得部２３、点検結果送信部２４、点検設備ＤＢ２５、を備える。点検管理装置１０及び設備状態取得装置２０は、コンピュータとプログラムによっても実現でき、プログラムを記録媒体に記録することも、ネットワークを通して提供することも可能である。 FIG. 2 shows a functional block diagram of the inspection management device 10 and the equipment status acquisition device 20. The inspection management device 10 includes an inspection result reception unit 11 , an inspection photo consistency determination unit 12 , an evaluation fluctuation value provision unit 13 , an inspection result DB 14 , an inspection equipment DB 15 and an inspection command generation unit 16 . The equipment status acquisition device 20 includes an inspection command receiving unit 21, an inspection command display unit 22, an inspection photo acquiring unit 23, an inspection result transmitting unit 24, and an inspection equipment DB 25. The inspection management device 10 and the facility condition acquisition device 20 can also be realized by a computer and a program, and the program can be recorded on a recording medium or provided through a network.
　点検指令生成部１６は、点検指令を生成する。点検指令受信部２１は、点検管理装置１０で生成された点検指令を受信する。点検指令表示部２２は、点検指令受信部２１で受信した点検指令を表示する。点検写真取得部２３は、点検写真を取得する。点検写真は、点検対象設備の撮影された点検画像である。点検結果送信部２４は、点検写真取得部２３の取得した点検写真を点検結果として点検管理装置１０に送信する。 The inspection command generation unit 16 generates an inspection command. The inspection command receiving unit 21 receives inspection commands generated by the inspection management device 10 . The inspection command display portion 22 displays the inspection command received by the inspection command receiving portion 21 . The inspection photo acquisition unit 23 acquires an inspection photo. An inspection photograph is an inspection image of the facility to be inspected. The inspection result transmission unit 24 transmits the inspection photo acquired by the inspection photo acquisition unit 23 to the inspection management device 10 as an inspection result.
　点検結果受信部１１は、設備状態取得装置２０の点検結果を受信する。点検写真整合性判定部１２は、点検結果受信部１１の受信した点検結果について、点検対象設備の状態に整合性が取れるか否かを判定する。判定は、点検結果に含まれている点検写真を、点検結果ＤＢ１４に格納されている点検対象設備の状態と比較することで行う。 The inspection result receiving unit 11 receives the inspection result of the equipment condition acquisition device 20. The inspection photo consistency determination unit 12 determines whether or not the inspection result received by the inspection result receiving unit 11 matches the state of the facility to be inspected. The determination is made by comparing the inspection photograph included in the inspection result with the state of the facility to be inspected stored in the inspection result DB 14 .
　評価変動値付与部１３は、点検写真整合性判定部１２の判定結果に基づいて、点検画像の送信元の設備状態取得装置２０の評価を行う。評価は、設備状態取得装置２０を操作する点検者の点検精度を評価可能な任意のパラメータを用いることができる。評価の結果は点検結果ＤＢ１４に格納される。 Based on the determination result of the inspection photo consistency determination unit 12, the evaluation fluctuation value provision unit 13 evaluates the facility state acquisition device 20 that is the transmission source of the inspection image. For the evaluation, any parameter that can evaluate the inspection accuracy of the inspector who operates the facility condition acquisition device 20 can be used. The evaluation result is stored in the inspection result DB 14 .
　点検指令生成部１６は、点検結果ＤＢ１４を参照し、評価変動値付与部１３の評価の結果に基づいて、点検指令を生成する。例えば、評価の高い点検者の設備状態取得装置２０への点検指令の送信量を、評価の低い点検者の設備状態取得装置２０への点検指令の送信量よりも多くする。また、評価の高い点検者の設備状態取得装置２０を優先して点検指令を送信するなど、評価の結果に応じた点検指令の送信を行うことができる。
　以下、各構成の動作及び機能について詳述する。 The inspection command generating unit 16 refers to the inspection result DB 14 and generates an inspection command based on the evaluation result of the evaluation variation value providing unit 13 . For example, the amount of inspection commands sent to the equipment state acquisition device 20 by an inspector with a high evaluation is made larger than the amount of inspection commands sent to the equipment state acquisition device 20 by an inspector with a low evaluation. In addition, it is possible to transmit an inspection command according to the evaluation result, such as transmitting an inspection command preferentially to the equipment status acquisition device 20 of an inspector with a high evaluation.
The operation and function of each component will be described in detail below.
　図３及び図４は、同一の地域に配置されている点検対象設備に対する点検指令の例である。点検管理装置１０は各点検者に対して、点検指令（点検者Ａ）のように道路などに沿った点検ルートや、点検指令（点検者Ｂ）のように面的な点検エリアを指令する。点検指令を受信した点検者Ａの設備状態取得装置２０の点検指令表示部２２には、図３に示すような、設備の配置されている位置、及び設備のうちのどれが点検対象設備であるかが、地図上に示されている画像が表示される。点検指令を受信した点検者Ｂの設備状態取得装置２０の点検指令表示部２２には、図４に示すような画像が表示される。 　Figures 3 and 4 are examples of inspection commands for inspection target equipment located in the same area. The inspection management device 10 issues an inspection route along a road, such as an inspection command (inspector A), or a planar inspection area, such as an inspection command (inspector B), to each inspector. In the inspection command display unit 22 of the equipment status acquisition device 20 of the inspector A who received the inspection command, as shown in FIG. However, the image shown on the map is displayed. An image as shown in FIG. 4 is displayed on the inspection command display unit 22 of the equipment status acquisition device 20 of the inspector B who received the inspection command.
　また全ての点検対象設備は識別のための設備ＩＤを持っており、点検管理装置１０の点検設備ＤＢ１５で管理されている。設備状態取得装置２０の点検設備ＤＢ２５にも、点検指令で受信した、あるいは事前に点検管理装置１０から受信した、点検設備ＤＢ１５と同様の情報が格納される。 In addition, all inspection target equipment has an equipment ID for identification, which is managed by the inspection equipment DB 15 of the inspection management device 10. The inspection facility DB 25 of the facility state acquisition device 20 also stores the same information as the inspection facility DB 15 received by the inspection command or received in advance from the inspection management device 10 .
　各点検者は指令を受けた点検対象設備を設備状態取得装置２０で撮影する。このとき、設備状態取得装置２０の点検指令表示部２２は、点検者へ点検写真の撮影方法を表示する。例えば「北方向から全体が根本から先端まで写るように撮影すること」といった内容である。点検指令表示部２２への表示方法は任意であるが、例えば、図４に示す画像上に、撮影する位置ＰＢを表示し、位置ＰＢをタップするなどして選択した際に撮影方法を表示してもよい。点検者は、点検写真取得部２３を用いて、点検指令表示部２２に表示された点検指令の通りに撮影する。これにより、点検対象設備の知識や点検技術を持たない点検者であっても、点検管理装置１０に蓄積された指令通りに撮影することができる。 Each inspector takes a picture of the facility to be inspected that received the instruction with the facility status acquisition device 20. At this time, the inspection command display unit 22 of the facility condition acquisition device 20 displays the method of photographing inspection photographs to the inspector. For example, the contents are such as "shoot from the north so that the whole can be seen from the base to the tip". Although the display method on the inspection command display unit 22 is arbitrary, for example, the position PB to be photographed is displayed on the image shown in FIG. 4, and the photographing method is displayed when the position PB is selected by tapping. may The inspector uses the inspection photo acquisition unit 23 to take a photograph according to the inspection command displayed on the inspection command display unit 22 . As a result, even an inspector who does not have knowledge of the equipment to be inspected or inspection techniques can take pictures according to the instructions stored in the inspection management device 10 .
　点検結果送信部２４は、設備ＩＤ及び点検写真を含む点検結果を、点検管理装置１０に向けて送信する。点検結果は、設備ＩＤ及び点検写真に代えて、又は設備ＩＤ及び点検写真と共に、点検写真のメタデータが含まれていてもよい。メタデータには、設備状態取得装置２０に備わる撮像機能が写真に付与する任意の情報、例えば点検写真を撮像時の設備状態取得装置２０の位置情報及び時間が含まれていてもよい。 The inspection result transmission unit 24 transmits inspection results including equipment IDs and inspection photos to the inspection management device 10 . The inspection result may include metadata of the inspection photo instead of or together with the equipment ID and inspection photo. The metadata may include arbitrary information given to the photograph by the imaging function provided in the facility state acquisition device 20, such as position information and time of the facility state acquisition device 20 when the inspection photo was taken.
　また、点検結果送信部２４は、点検写真のメタデータに基づいて設備ＩＤを導出してもよい。例えば、メタデータに含まれる位置情報が図４に示す位置ＰＢである場合、位置ＰＢでの撮影を点検指令で行っている図４に示す点検対象設備の設備ＩＤの全てを設備ＩＤとして送信してもよい。 Also, the inspection result transmission unit 24 may derive the equipment ID based on the metadata of the inspection photo. For example, if the position information included in the metadata is the position PB shown in FIG. 4, all the equipment IDs of the equipment to be inspected shown in FIG. may
　図５は図４とは同じ点検対象設備に対する異なる点検指令の例である。図５及び図４と同じ地域の地図を示す。図４の点検指令に含まれていた設備の一部が、点検者Ｃ及びＤへの点検指令に含まれている。このように、点検管理装置１０は同一の点検対象設備に関して同じ点検者の設備状態取得装置２０へ点検指令することもあるが、図４と図５の違いのように、複数の異なる点検者が同一の点検対象設備を複数回点検するように指令してもよい。 　Fig. 5 is an example of a different inspection command for the same equipment to be inspected as in Fig. 4. Figure 5 shows a map of the same area as Figures 5 and 4; A part of the equipment included in the inspection instruction of FIG. 4 is included in the inspection instruction to the inspectors C and D. In this way, the inspection management device 10 may issue an inspection command to the equipment status acquisition device 20 by the same inspector regarding the same inspection target equipment. It may be instructed to inspect the same facility to be inspected multiple times.
　図６は、点検管理装置１０が管理するデータベースの例である。
　点検設備ＤＢ１５は、電柱やマンホール等、公の場所に設置されている点検対象設備の情報を格納する。点検対象設備の情報は、点検対象設備を特定可能な設備ＩＤ、設備名称、設備の設置場所など、点検対象設備の任意の情報を含む。
　点検結果ＤＢ１４は、点検結果受信部１１の受信した点検写真を格納する。点検結果ＤＢ１４は、点検日時、点検者ＩＤ、評価変動値を含んでいてもよい。 FIG. 6 is an example of a database managed by the inspection management device 10. As shown in FIG.
The inspection facility DB 15 stores information on inspection target facilities installed in public places, such as utility poles and manholes. The information on the equipment to be inspected includes arbitrary information on the equipment to be inspected, such as an equipment ID that can identify the equipment to be inspected, the name of the equipment, and the installation location of the equipment.
The inspection result DB 14 stores inspection photographs received by the inspection result receiving unit 11 . The inspection result DB 14 may include inspection date/time, inspector ID, and evaluation fluctuation value.
　点検結果ＤＢ１４は、設備状態取得装置２０を操作する点検者の情報を格納する点検者テーブルをさらに格納する。点検者テーブルは、点検者を特定可能な点検者ＩＤ、点検者名、合計評価値を含む。合計評価値は、点検者それぞれの点検精度を表すパラメータであり、当該点検者の過去の変動評価値の合算によって定められる。 The inspection result DB 14 further stores an inspector table that stores information on inspectors who operate the equipment status acquisition device 20 . The inspector table includes inspector IDs that can identify inspectors, inspector names, and total evaluation values. The total evaluation value is a parameter representing the inspection accuracy of each inspector, and is determined by summing the past fluctuation evaluation values of the inspector.
　点検管理装置１０では、点検写真整合性判定部１２が、点検者の撮影した点検写真に写っている点検対象設備の状態に整合性が取れるか否かを、画像処理を用いて自動的に判定する。ここで、判定においては、点検管理装置１０の利用者による手作業が含まれていてもよい。評価変動値付与部１３は、点検写真整合性判定部１２の判定に基づいて、評価変動値を決める。そして、評価変動値付与部１３がそれらの評価変動値を点検者毎の変動評価値に合算することで、点検者それぞれの点検精度を評価するパラメータとする。 In the inspection management device 10, the inspection photo consistency determination unit 12 automatically determines whether or not the state of the equipment to be inspected shown in the inspection photo taken by the inspector is consistent using image processing. do. Here, the determination may include manual work by the user of the inspection management device 10 . The evaluation fluctuation value provision unit 13 determines an evaluation fluctuation value based on the judgment by the inspection photo consistency judgment unit 12 . Then, the evaluation fluctuation value providing unit 13 sums up the fluctuation evaluation values for each inspector to obtain a parameter for evaluating the inspection accuracy of each inspector.
　図７に評価変動値の判断フローを示す。
　点検写真が撮影された日時の前後で撮影された点検写真がなければ（Ｓ１０１においてＮｏ）、情報不十分である点検対象設備に対して点検を実施したとしてポジティブな値を評価変動値へ付与する（Ｓ１０４）。
　仮に前後の日時で撮影された点検写真がある場合は（Ｓ１０１においてＹｅｓ）、時系列に沿って点検対象設備の状態に整合性が取れるか否かを判断する（Ｓ１０２）。整合性がある場合は（Ｓ１０２においてＹｅｓ）、ポジティブな評価変動値を付与する（Ｓ１０４）。整合性が取れない場合は（Ｓ１０２においてＮｏ）、ネガティブな評価変動値を付与し、加えて、当該の点検結果を点検結果ＤＢ１４から削除し、または当該の点検者を点検者テーブルに以降のシステムでの使用を制限する注意を記録しておく（Ｓ１０３）。 FIG. 7 shows a judgment flow of the evaluation fluctuation value.
If there is no inspection photo taken before or after the date and time when the inspection photo was taken (No in S101), a positive value is given to the evaluation fluctuation value assuming that the inspection target equipment with insufficient information has been inspected. (S104).
If there are inspection photos taken before and after the date and time (Yes in S101), it is determined whether or not the state of the facility to be inspected is consistent in chronological order (S102). If there is consistency (Yes in S102), a positive evaluation fluctuation value is given (S104). If there is no consistency (No in S102), a negative evaluation fluctuation value is given, and the inspection result is deleted from the inspection result DB 14, or the inspector is added to the inspector table in subsequent systems. A caution for restricting the use of is recorded (S103).
　図７の評価フローを実施した例として図８、図９、図１０は、異なる日付、異なる点検者が同じ点検対象設備の撮影を行ったデータを並べた例を用いる。Ｎ日の点検写真に対して評価を行う場合、図８のように時系列順に並べた際に前後の点検写真と劣化状態が同様であれば、Ｎ日の点検結果には信憑性があり、評価変動値にポジティブな値を加算する（Ｓ１０４）。同様に、図９のように日を追うごとに電柱が傾くなど、劣化度が増している場合もＮ日の点検結果には信憑性があると判断し、評価変動値にポジティブな値を加算する（Ｓ１０４）。 　As an example of implementing the evaluation flow of Figure 7, Figures 8, 9, and 10 use examples in which the data of the same inspection target equipment photographed by different inspectors on different dates are arranged. When evaluating the inspection photos on the Nth day, if the inspection photos before and after and the deterioration state are the same when arranged in chronological order as shown in FIG. A positive value is added to the evaluation fluctuation value (S104). Similarly, as shown in Fig. 9, even if the degree of deterioration is increasing, such as when the utility pole tilts with each passing day, the inspection results on Day N are judged to be credible, and a positive value is added to the evaluation fluctuation value. (S104).
　一方で図１０のようにＮ日の前後では電柱が傾いているにも関わらず、Ｎ日だけ電柱が元に戻っているような場合、当該の日付に修復工事等が行われていなければ、Ｎ日の点検結果には信憑性がなく、図１１のように、Ｎ日の点検結果を異常データとして判断して評価変動値にネガティブな値を加算し（Ｓ１０３）、点検者Ｂの合計評価値が低下するように処理を実行する。 On the other hand, as shown in FIG. 10, in the case where the utility pole is tilted before and after N days, but the utility pole returns to its original position only for N days, if no repair work or the like is performed on that date, As shown in FIG. 11, the inspection results for N days are judged to be abnormal data, and a negative value is added to the evaluation fluctuation value (S103) to obtain the total evaluation of inspector B. Take action to reduce the value.
　このようにして、点検結果から各点検者に合計評価値という形でスコアを付け、そのスコアに則って点検者への点検指令の出し方や指令量に変化をつける。また、点検管理装置１０は、点検結果ＤＢ１４に格納されている各点検者の合計評価値に則って、点検者への報酬へのフィードバックを行ってもよいし、点検者間の競争などに用いても良い。 In this way, a score is given to each inspector in the form of a total evaluation value based on the inspection results, and changes are made to how inspection commands are issued to inspectors and to the amount of commands according to the score. In addition, the inspection management device 10 may provide feedback on remuneration to the inspectors in accordance with the total evaluation value of each inspector stored in the inspection result DB 14, or may be used for competition among inspectors. can be
（本開示を実施するための第二形態）点検指令外の点検対象設備への点検実施
　第一形態の図３から図５のように点検指令を出しているもの以外について点検者が点検を実施した場合においても、第一形態と同様に点検結果ＤＢ１４へ記録し、図７の評価変動値の判断フローに則って処理を行う。ただし、点検指令を優先的に実行させるために指令外の点検対象設備に関する評価変動値の変動幅は点検指令に基づく点検対象設備に関する評価変動値に比べて小さくしても良い。 (Second form for carrying out the present disclosure) Inspection of equipment to be inspected outside inspection orders The inspector carries out inspections other than those for which inspection orders are issued as shown in Figures 3 to 5 of the first form. Even in the case where the evaluation variation value is determined, it is recorded in the inspection result DB 14 in the same manner as in the first embodiment, and processing is performed in accordance with the flow for determining the evaluation fluctuation value in FIG. 7 . However, in order to preferentially execute the inspection command, the fluctuation range of the evaluation fluctuation value for the equipment to be inspected other than the command may be smaller than the evaluation fluctuation value for the equipment to be inspected based on the inspection command.
（本開示を実施するための第三形態）点検者への還元
　第一、第二形態において、点検対象設備を保有する個人又は法人ではない点検対象者は、点検写真を撮ることに対してメリットがなければ撮影しない。そこで、点検を実施した者へ経済的見返りを提供しても良い。例えばカードやアプリ上にポイントを付与することである。カードには種類がいくつかあるが、例えば点検対象設備を保有する法人が提供するポイントカードや、交通系カード（Ｓｕｉｃａ）などがある。 (Third form for carrying out the present disclosure) Returns to inspectors I don't shoot without it. Therefore, an economic reward may be provided to the person who performed the inspection. For example, giving points on cards or apps. There are several types of cards, including, for example, a point card provided by a corporation that owns facilities to be inspected, a transportation card (Suica), and the like.
（本開示を実施するための第四形態）正当でない点検結果への対応
　第一、第二、第三形態にて経済的見返りを提供することにより、正当な点検結果ではない写真を送るものがいる可能性がある。それらは画像処理によって機械的に、または点検管理装置１０の管理者による手動で判別する。 (Fourth Mode for Carrying Out the Present Disclosure) Responding to Invalid Inspection Results Those who send photos that are not valid inspection results by providing economic rewards in the first, second, and third modes there may be. They are determined mechanically by image processing or manually by an administrator of the inspection management device 10 .
　例えば同一の写真や一部を画像処理で編集しただけの画像、同じ点検対象設備を短い時間に大量に撮影して送るなどを繰り返し実行してきた場合はパターンマッチングや特徴点抽出および過去の写真との照合により検出する。こういった意図的に点検管理装置１０の運用を妨げる行為をする点検者に対しては、図６の合計評価値に大幅なペナルティを与える。合計評価値が一定の閾値を下回った点検者に対しては経済的見返り量の制限や停止、点検指令の制限や停止、点検管理システムからの除外等の措置を講じても良い。 For example, if you repeatedly send the same photo, a partially edited image, or a large number of photos of the same equipment to be inspected in a short period of time, pattern matching, feature point extraction, and comparison with past photos Detected by matching. A significant penalty is given to the total evaluation value in FIG. For an inspector whose total evaluation value is below a certain threshold, measures such as limiting or suspending the amount of economic reward, restricting or suspending inspection orders, or excluding the inspector from the inspection management system may be taken.
