　この発明は、各種の検査対象物であって、例えば転がり軸受や等速ボールジョイント等の回転機械部品からなる検査対象物につき、一般に普及しているスマートフォン等の携帯情報端末器を用いた検査を可能にした携帯端末利用検査システムおよびそのサーバに関する。 The present invention relates to various inspection objects, for example, inspection objects made of rotating machine parts such as rolling bearings and constant velocity ball joints, and inspection using a portable information terminal such as a smartphone that is widely used. The present invention relates to a portable terminal usage inspection system and a server thereof.
　従来、軸受等の回転機械部品の検査システムとして、軸受の振動の測定を行い、異常等を検査する方法がある。この検査システムとして、一般に普及している携帯情報端末器に振動センサの検出結果を入力することで、軸受等の回転機械部品の動作状態を簡易に検査可能としたものが提案されている。（例えば、特許文献１）。 Conventionally, as an inspection system for rotating machine parts such as a bearing, there is a method of measuring an abnormality of the bearing by measuring vibration of the bearing. As this inspection system, there has been proposed a system in which the operation state of rotating machine parts such as a bearing can be easily inspected by inputting a detection result of a vibration sensor into a widely used portable information terminal. (For example, patent document 1).
　この他に、回転機械部品の検査に用いる装置として、音響センサ装置が提案されている（例えば、特許文献２）。その音響センサは例えばマイクロフォンを含み、このマイクロフォンが、検査対象物が発する音を集音する。 In addition, an acoustic sensor device has been proposed as a device used for inspection of rotating machine parts (for example, Patent Document 2). The acoustic sensor includes, for example, a microphone, and the microphone collects sound emitted from the inspection object.

　しかし、振動を検出するためには、ピックアップ等の特別な専用センサを用いる。また、専用センサで検出した信号を携帯情報端末器に入力するには、専用センサで検出したアナログ信号をディジタル信号に変換するためのＡ／Ｄ変換器が必要となり、さらにこれら専用センサおよびＡ／Ｄ変換器を作動させる電源が必要となる。したがって、携帯性に優れないうえ、高価になり得る。 However, a special dedicated sensor such as a pickup is used to detect vibration. In addition, in order to input a signal detected by the dedicated sensor to the portable information terminal, an A / D converter for converting the analog signal detected by the dedicated sensor into a digital signal is required. A power source for operating the D converter is required. Therefore, it is not excellent in portability and can be expensive.
　なお、前記従来の音響センサ装置を開示した特許文献２は、磁石等で検査対象物に取付けることが記載されているが、単に検出機能を有するセンサ装置として記載されていて、検出した音響信号を解析する装置やその装置への信号の送受についての具体的な開示はない。 In addition, Patent Document 2 that discloses the conventional acoustic sensor device is described as being attached to an inspection object with a magnet or the like, but is simply described as a sensor device having a detection function, and the detected acoustic signal is There is no specific disclosure about the device to be analyzed and the transmission and reception of signals to that device.
　この発明の目的は、特別な専用センサが不要で、検査に使用される機器の携帯性に優れ、かつ安価に構築できる携帯端末利用検査システムおよびそのサーバを提供することである。 An object of the present invention is to provide a portable terminal utilization inspection system and a server thereof that do not require a special dedicated sensor, are excellent in portability of equipment used for inspection, and can be constructed at low cost.
　以下、便宜上理解を容易にするために、実施形態の符号を参照して説明する。 Hereinafter, in order to facilitate understanding, description will be made with reference to the reference numerals of the embodiments.
　この発明の第１の構成に係る携帯端末利用検査システムは、第１のマイクロフォン３を内蔵するかまたは第２のマイクロフォン３Ａのための接続部を含み、画像を出力する画面表示装置２１を有する少なくとも１つの汎用の携帯情報端末器２と、
　前記少なくとも１つの携帯情報端末器２に通信回線網７によって接続されるサーバ６とを備え、
　前記少なくとも１つの携帯情報端末器２が、検査対象物１が発する音（つまり、検査対象物１近傍の音）を前記第１または第２のマイクロフォン３または３Ａで集音して録音した音響データを前記サーバ６に送信する音響データ送信手段３５、およびその音響データに対して前記サーバ６から返送される処理結果を前記画面表示装置２１の画面に表示する処理結果表示手段３６を有し、
　前記サーバ６が、前記少なくとも１つの携帯情報端末器２から送信された音響データを受信する受信処理手段１３、この受信した音響データを解析して異常の有無を判定するデータ処理手段４、およびこのデータ処理手段４の処理結果を前記携帯情報端末器２へ返送する処理結果返送手段１４を有する。 The portable terminal use inspection system according to the first configuration of the present invention includes at least a screen display device 21 that includes the first microphone 3 or includes a connection portion for the second microphone 3A and outputs an image. One general-purpose portable information terminal 2;
A server 6 connected to the at least one portable information terminal 2 by a communication network 7;
Acoustic data recorded by the at least one portable information terminal 2 collecting sound recorded by the inspection object 1 (that is, sound near the inspection object 1) with the first or second microphone 3 or 3A. Acoustic data transmitting means 35 for transmitting the data to the server 6, and processing result display means 36 for displaying the processing result returned from the server 6 for the acoustic data on the screen of the screen display device 21,
The server 6 receives the acoustic data transmitted from the at least one portable information terminal 2, the data processing means 4 that analyzes the received acoustic data and determines whether there is an abnormality, and the Processing result returning means 14 for returning the processing result of the data processing means 4 to the portable information terminal 2 is provided.
　この構成によると、検査対象物１が発する音を前記第１または第２のマイクロフォン３（３Ａ）で集音して録音した音響データをサーバ６に送信し、サーバ６により音響データを解析して異常の有無を判定するため、サーバ６の持つ高性能の処理機能を利用して音響データの解析および異常判定を行うことができる。処理結果がサーバ６から携帯情報端末器２へ返送されるため、携帯情報端末器２で異常判定結果等の処理結果を表示することにより、作業者が処理結果を知ることができる。 According to this configuration, the sound data recorded by collecting the sound emitted from the inspection object 1 with the first or second microphone 3 (3A) is transmitted to the server 6, and the server 6 analyzes the sound data. In order to determine the presence / absence of abnormality, it is possible to analyze the acoustic data and determine abnormality using the high-performance processing function of the server 6. Since the processing result is returned from the server 6 to the portable information terminal 2, the operator can know the processing result by displaying the processing result such as the abnormality determination result on the portable information terminal 2.
　また、異常判定に音響データを用いるが、スマートフォンやタブレット等の携帯情報端末器２はマイクロフォンを一般的に内蔵しており、この内蔵のマイクロフォンを第１のマイクロフォン３として用いることで、外部機器を接続することなく、検査データの収集、つまり集音して音響データの録音が行える。そのため、携帯情報端末器２のみで、検査データの収集からその送信、処理結果の表示までを行える。 Moreover, although acoustic data is used for abnormality determination, the portable information terminal device 2 such as a smartphone or a tablet generally has a built-in microphone. By using this built-in microphone as the first microphone 3, an external device can be used. Without connection, it is possible to collect inspection data, that is, collect sound and record acoustic data. Therefore, only the portable information terminal 2 can perform the collection of inspection data, transmission of the inspection data, and display of the processing result.
　集音および音響データの録音に、外付けの第２のマイクロフォン３Ａを用いる場合は、指向性の高いマイクロフォンを用いることで、検査対象物１の特定の部位から発せられる音響を効率的つまりほとんど雑音なく、集音して録音することができる。この場合は外付けの第２のマイクロフォン３Ａが必要であるが、市販されている一般のマイクロフォンを用いれば良く、特別な専用センサは不用である。携帯情報端末器２がマイク入力端子４４を有する場合は、外付けのＡ／Ｄ変換器も不要となる。 When the external second microphone 3A is used for collecting sound and recording sound data, by using a highly directional microphone, sound emitted from a specific part of the inspection object 1 is efficiently, that is, almost no noise. Without collecting, you can record. In this case, an external second microphone 3A is required, but a commercially available general microphone may be used, and a special dedicated sensor is unnecessary. When the portable information terminal 2 has the microphone input terminal 44, an external A / D converter is also unnecessary.
　このように、一般的な携帯情報端末器２を検査対象物の検査のための音響データの取得に使用し、特別な専用センサを使用しないため、安価に検査システムを構築できる。
　また、この携帯端末利用検査システムによると、特別な専用センサが不要であるため、検査に使用する機器の携帯性に優れる。 Thus, since the general portable information terminal 2 is used for acquiring acoustic data for inspecting the inspection object and no special dedicated sensor is used, an inspection system can be constructed at low cost.
Moreover, according to this portable terminal utilization test | inspection system, since a special exclusive sensor is unnecessary, it is excellent in the portability of the apparatus used for a test | inspection.

Instead, the sound data collected and recorded by the microphone 3 may be temporarily stored in the recording data storage means 43 provided in the portable information terminal 2, and the stored sound data may be transmitted. The recorded data storage means 43 may be a function that the portable information terminal 2 has as a standard function or the like, or a function that is provided exclusively for this portable terminal usage inspection system.
　前記音響データ送信手段３５および前記処理結果表示手段３６は、前記アプリケーションプログラムの一つである検査プログラム３３により一部が構成される。すなわち、前記検査プログラム３３がインストールされることで、携帯情報端末器２のハードウェア部分、ＯＳ９、および前記検査プログラム３３により、前記音響データ送信手段３５、前記処理結果表示手段３６、および随意に録音データ記憶手段４３が構成される。前記検査プログラム３３は、携帯情報端末器２からの所定の要求に応じてサーバ６の検査プログラム配信手段４１から配信される。 The acoustic data transmission unit 35 and the processing result display unit 36 are partially configured by an inspection program 33 which is one of the application programs. That is, by installing the inspection program 33, the acoustic data transmission means 35, the processing result display means 36, and optionally the recording are performed by the hardware portion of the portable information terminal 2, the OS 9, and the inspection program 33. Data storage means 43 is configured. The inspection program 33 is distributed from the inspection program distribution means 41 of the server 6 in response to a predetermined request from the portable information terminal 2.
　前記サーバ６は、例えば、軸受メーカ等の検査対象物１を製造するメーカのデータセンタ等に設けられる。前記サーバ６は、１台のコンピュータから構成されても良い。代わりに、複数台の互いに接続されたコンピュータで構成されても良い。前記サーバ６は、携帯情報端末器２から送信された音響データを受信する受信処理手段１３、この受信した音響データを解析して異常の有無を判定するデータ処理手段４、およびこのデータ処理手段４の処理結果を前記携帯情報端末器２へ返送する処理結果返送手段１４を有する。 The server 6 is provided, for example, in a data center of a manufacturer that manufactures the inspection object 1 such as a bearing manufacturer. The server 6 may be composed of a single computer. Instead, a plurality of computers connected to each other may be used. The server 6 includes a reception processing unit 13 that receives acoustic data transmitted from the portable information terminal 2, a data processing unit 4 that analyzes the received acoustic data to determine whether there is an abnormality, and the data processing unit 4 The processing result returning means 14 for returning the processing result to the portable information terminal 2 is provided.
　受信処理手段１３は、受信した音響データを、その音響データと共に送信された検査対象物１の識別情報や検査を特定するための情報と共に、所定の記憶手段に記憶させる。
　処理結果返送手段１４は、データ処理手段４の処理結果を、前記検査対象物１の識別情報や検査を特定するための情報と共に、携帯情報端末器２へ返送する。 The reception processing unit 13 stores the received acoustic data in a predetermined storage unit together with the identification information of the inspection object 1 transmitted together with the acoustic data and information for specifying the inspection.
The processing result returning means 14 returns the processing result of the data processing means 4 to the portable information terminal 2 together with the identification information of the inspection object 1 and information for specifying the inspection.
　データ処理手段４は、受信した音響データを解析する解析部４ａ、およびその解析結果から検査対象物１の異常の有無を判定する異常判定部４ｂを有する。解析部４ａは、音響データを周波数分析する機能、音響データの周波数範囲を制限するフィルタ機能、および音響データの音響レベルの実効値を計算する機能のうちの少なくとも１つを有する。異常判定部４ｂは、解析部４ａが有する前記機能によって得たデータを所定の閾値や許容範囲等と比較して検査対象物１が異常であるか否かを判定する。周波数分析を行う場合、検査対象物１の部位毎の周波数特性を参照することで、検査対象物１のどの部位の異常であるかの判定を行うことも可能になる。 The data processing unit 4 includes an analysis unit 4a that analyzes the received acoustic data, and an abnormality determination unit 4b that determines whether the inspection object 1 is abnormal based on the analysis result. The analysis unit 4a has at least one of a function of analyzing the frequency of the acoustic data, a filter function of limiting the frequency range of the acoustic data, and a function of calculating an effective value of the acoustic level of the acoustic data. The abnormality determination unit 4b determines whether or not the inspection object 1 is abnormal by comparing data obtained by the function of the analysis unit 4a with a predetermined threshold value, an allowable range, or the like. When performing frequency analysis, it is also possible to determine which part of the inspection object 1 is abnormal by referring to the frequency characteristics of each part of the inspection object 1.
　この異常の判定には、検査対象物１の仕様についてのデータベース１６を用いても良い。このデータベース１６には、検査対象物１の型番毎の異常判定の閾値等が登録されている。データベース１６は、サーバ６の一部として設けられたものであっても、サーバ６とは別に設けられてサーバ６が検索可能となるように接続されたものであっても良い。データベース１６には、検索項目１６ａと、種々の検査対象物１の仕様のデータ１６ｂとが登録されている。異常判定の閾値等は、仕様のデータ１６ｂの一部として登録されていても、また仕様のデータ１６ｂから計算されても良い。 The database 16 regarding the specification of the inspection object 1 may be used for determining this abnormality. In this database 16, a threshold value for abnormality determination for each model number of the inspection object 1 is registered. The database 16 may be provided as a part of the server 6 or may be provided separately from the server 6 and connected so that the server 6 can be searched. In the database 16, search items 16a and data 16b of specifications of various inspection objects 1 are registered. The abnormality determination threshold value or the like may be registered as a part of the specification data 16b or may be calculated from the specification data 16b.
　この構成によると、検査対象物１が発する音を第１のマイクロフォン３で集音して録音した音響データをサーバ６に送信し、サーバ６により音響データを解析して異常の有無を判定するため、サーバ６の持つ高性能の処理機能を利用して音響データの解析および異常判定を行うことができる。処理結果がサーバ６から携帯情報端末器２へ返送されるため、携帯情報端末器２で異常判定結果等の処理結果を表示することにより、作業者が処理結果を知ることができる。 According to this configuration, the acoustic data recorded by collecting the sound generated by the inspection object 1 with the first microphone 3 is transmitted to the server 6, and the acoustic data is analyzed by the server 6 to determine whether there is an abnormality. The acoustic data can be analyzed and the abnormality can be determined using the high-performance processing function of the server 6. Since the processing result is returned from the server 6 to the portable information terminal 2, the operator can know the processing result by displaying the processing result such as the abnormality determination result on the portable information terminal 2.
　また、異常判定に音響データを用いるが、スマートフォンやタブレット等の携帯情報端末器２はマイクロフォンを一般的に内蔵しており、この内蔵のマイクロフォンを第１のマイクロフォン３として用いることで、外部機器を接続することなく、検査データの収集、つまり集音して音響データの録音が行える。そのため、携帯情報端末器２のみで、検査データの収集からその送信、処理結果の表示までを行える。 Moreover, although acoustic data is used for abnormality determination, the portable information terminal device 2 such as a smartphone or a tablet generally has a built-in microphone. By using this built-in microphone as the first microphone 3, an external device can be used. Without connection, it is possible to collect inspection data, that is, collect sound and record acoustic data. Therefore, only the portable information terminal 2 can perform the collection of inspection data, transmission of the inspection data, and display of the processing result.
　このように、一般的な携帯情報端末器２のみを検査対象物の検査のための音響データの取得に使用するので、特別な専用センサが不要である。そのため、安価に検査システムを構築できる。特に、この実施形態のように内蔵のマイクロフォンを第１のマイクロフォン３として利用する場合は、携帯情報端末器２に他の機器を接続する必要が全くなく、携帯情報端末器２に検査プログラム３３をダウンロードしてインストールするだけで、一般の携帯情報端末器２自体を、この携帯端末利用検査システムを構成する音響データ検査用の機器として使用できる。 Thus, since only the general portable information terminal 2 is used for acquiring acoustic data for the inspection of the inspection object, a special dedicated sensor is unnecessary. Therefore, an inspection system can be constructed at a low cost. In particular, when the built-in microphone is used as the first microphone 3 as in this embodiment, there is no need to connect any other device to the portable information terminal 2, and the inspection program 33 is stored in the portable information terminal 2.
