Description

データ収集システム及びデータ収集方法Data collection system and data collection method
　本発明は、データ収集システム及びデータ収集方法に関する。 The present invention relates to a data collection system and a data collection method.
　設備の稼働状況やトラブル発生などを解析するために、設備の動作状態を経時的にデータ記録するロギング装置が知られている。例えば、特許文献１には、設備を制御する設備制御手段からロギングデータを取り出す装置が開示されている。また、特許文献２には、設備に各種センサを取り付けて当該センサからロギングデータを取り出す装置が開示されている。 A logging device is known that records data on the operating state of equipment over time in order to analyze equipment operating status and trouble occurrence. For example, Patent Document 1 discloses an apparatus that extracts logging data from equipment control means for controlling equipment. Patent Document 2 discloses a device for attaching various sensors to equipment and extracting logging data from the sensors.

　しかしながら、従来のロギング装置の構成によれば、設備制御手段又はセンサのいずれか一方からのロギングデータしか活用できないため、設備の状態に合わせた層別の分析を行うことができなかった。また、設備制御手段とセンサはそれぞれが独立した時間軸に基づいてロギングされるため、例えば、設備のトラブル発生時を起点に両者を同期させたデータに基づく分析を行うことは困難であった。なお、データをロギングするとともに人手作業によって設備を監視することも考えられるが、多大な時間と労力を要する上、例えば、電子部品の製造設備においては設備が高速稼働であることから、トラブル発生の瞬間など不規則なトリガ発生に対応したデータ収集は不可能であった。 However, according to the configuration of the conventional logging device, only logging data from either the equipment control means or the sensor can be used, and therefore, the analysis according to the layer according to the state of the equipment cannot be performed. In addition, since the facility control means and the sensor are logged based on independent time axes, for example, it has been difficult to perform an analysis based on data obtained by synchronizing both from the time of occurrence of a trouble in the facility. It is also possible to log data and monitor the equipment manually, but it takes a lot of time and labor.For example, in equipment for manufacturing electronic parts, the equipment operates at high speed, so troubles may occur.

　図１に示すように、設備ロギング装置１０は、ネットワークを介して複数の設備４０と通信可能に接続されている。このネットワークは、設備４０が置かれた施設内に構築するＬＡＮ（ｌｏｃａｌ　ａｒｅａ　ｎｅｔｗｏｒｋ）等を含む情報処理に係る通信回線又は通信網であり、有線又は無線のいずれであってもよい。あるいは、複数の施設にそれぞれ置かれた設備４０同士を基地局や無線ＬＡＮのアクセスポイントやインターネットなどを介して通信接続してもよい。 As shown in FIG. 1, the facility logging device 10 is connected to a plurality of facilities 40 through a network. This network is a communication line or a communication network related to information processing including a LAN (local area network) constructed in a facility where the equipment 40 is placed, and may be either wired or wireless. Alternatively, the facilities 40 placed in a plurality of facilities may be connected to each other via a base station, a wireless LAN access point, the Internet, or the like.
　複数の設備４０は、それぞれ、制御装置４２と機器４４とを含む。制御装置４２は、機器４４を動作させる入力データを機器４４に送るとともに、機器４４の動作状態を検出する１つ又は複数の検出手段４６から出力データを取得するように構成されている。複数の設備４０は互いに同一機能を備えていてもよいし、異なる機能を備えていてもよい。 Each of the plurality of facilities 40 includes a control device 42 and a device 44. The control device 42 is configured to send input data for operating the device 44 to the device 44 and to acquire output data from one or more detection means 46 that detect the operating state of the device 44. The plurality of facilities 40 may have the same function, or may have different functions.
　図１に示す例では、機器４４はシリンダである。この場合、検出手段４６は、例えば、シリンダの回転（例えば回転数）、ソレノイドの動作（例えばオン／オフ）、シリンダの位置を検出するオートスイッチの動作（例えばオン／オフ）、サイクルタイムオーバーの発生有無などを検出する。なお、機器４４は、上記一例に限定されるものではなく、設備４０の加工処理に応じてその機能又は構成は様々である。 In the example shown in FIG. 1, the device 44 is a cylinder.

In addition, the apparatus 44 is not limited to the above example, and its function or configuration varies depending on the processing of the equipment 40.
　設備ロギング装置１０は、複数の設備４０のうち、１つ又は複数の設備４０に関するロギングデータを記録する。また、設備ロギング装置１０は、１つの設備４０について１つ又は複数の特性に対応するロギングデータを記録する。例えば機器４４がシリンダである場合、設備ロギング装置１０は、シリンダの回転数、ソレノイドのオン／オフ状態、オートスイッチのオン／オフ、サイクルタイムオーバーの発生有無などの各ロギングデータを記録する。 The facility logging device 10 records logging data related to one or a plurality of facilities 40 among the plurality of facilities 40. Further, the facility logging apparatus 10 records logging data corresponding to one or a plurality of characteristics for one facility 40. For example, when the device 44 is a cylinder, the equipment logging device 10 records each logging data such as the number of rotations of the cylinder, the solenoid on / off state, the auto switch on / off, and the occurrence of cycle time over.
　センサロギング装置２０は、ネットワークを介して複数のセンサ５０と通信可能に接続されている。このネットワークは、設備ロギング装置１０について説明した構成を適用することができる。 The sensor logging device 20 is communicably connected to a plurality of sensors 50 via a network. The configuration described for the equipment logging apparatus 10 can be applied to this network.
　センサ５０は、設備４０の機器４４の動作状態を検出する。センサ５０は、例えば、設備４０の機器４４に取り外し可能に装着されている。この場合、センサロギング装置２０は、設備４０に対して取り付け及び取り外し可能なハンドキャリー型の装置である。例えば、固定型の設備ロギング装置１０に対して、ハンドキャリー型のセンサロギング装置２０を用いることによって、センサ５０と設備４０の組み合わせを自由に組み替えることができる。 The sensor 50 detects the operating state of the equipment 44 of the facility 40. The sensor 50 is detachably mounted on the equipment 44 of the facility 40, for example. In this case, the sensor logging device 20 is a hand carry type device that can be attached to and detached from the facility 40. For example, the combination of the sensor 50 and the facility 40 can be freely rearranged by using the hand carry type sensor logging device 20 with respect to the fixed facility logging apparatus 10.
　センサロギング装置２０は、複数のセンサ５０のうち、１つ又は複数の設備４０に関するロギングデータを記録する。また、センサロギング装置２０は、１つの設備４０について１つ又は複数の特性に対応するロギングデータを記録する。図１に示す例では、設備４０がシリンダである場合、センサロギング装置２０は、変位センサ５２によってシリンダの変位量を記録することができる。センサロギング装置２０と設備ロギング装置１０とでロギングデータを記録する対象となる設備を一致させることによって、設備に関する複数の特性に対応するロギングデータを記録及び取得することができる。 The sensor logging device 20 records logging data related to one or a plurality of facilities 40 among the plurality of sensors 50. In addition, the sensor logging device 20 records logging data corresponding to one or more characteristics for one facility 40. In the example shown in FIG. 1, when the facility 40 is a cylinder, the sensor logging device 20 can record the displacement amount of the cylinder by the displacement sensor 52.

The configuration described for the equipment logging apparatus 10 can be applied to this network. The data processing device 30 executes various processes for performing a predetermined analysis on the facility 40 based on the logging data collected using the facility logging device 10 and the sensor logging device 20.
　図２及び図３を用いて、設備ロギング装置１０、センサロギング装置２０及びデータ処理装置３０の機能構成及びハードウェア構成についてさらに詳述する。 2 and 3, the functional configuration and hardware configuration of the equipment logging device 10, the sensor logging device 20, and the data processing device 30 will be described in further detail.
　図２に示すように、設備ロギング装置１０は、設備ロギング装置１０のデータ収集に関わる動作全体を制御する制御部１１と、かかる動作に必要な情報を記憶するための記憶部１２とを有する。 As shown in FIG. 2, the facility logging apparatus 10 includes a control unit 11 that controls the entire operation related to data collection of the facility logging apparatus 10 and a storage unit 12 that stores information necessary for the operation.
　設備ロギング装置１０として、例えば図３に示すようなＣＰＵ１０１、ＲＯＭ１０２、ＲＡＭ１０３、通信Ｉ／Ｆ１０４、表示装置１０５、入力装置１０６、ＨＤＤ１０７、外部記憶装置１０８を備えるコンピュータを適用することができる。 As the equipment logging device 10, for example, a computer including a CPU 101, a ROM 102, a RAM 103, a communication I / F 104, a display device 105, an input device 106, an HDD 107, and an external storage device 108 as shown in FIG. 3 can be applied.
　設備ロギング装置１０は、例えばＣＰＵ１０２が、上記したＲＯＭ１０４、ＲＡＭ１０６、外部記憶装置１０８などに記憶された又はネットワークを介してダウンロードされた所定のプログラム（本実施形態に係るデータ収集方法を規定したプログラム）を実行することにより、設備ロギング装置１０を後述の各種機能ブロック又は各種ステップとして機能させることができる。なお、本実施形態に係るデータ収集方法を規定したプログラムがコンピュータに働きかけてＣＰＵ１０１に行わせる処理は、それぞれ本実施形態のデータ収集システム又は方法における対応する要素の機能及び動作と同一である。 For example, the equipment logging device 10 is a predetermined program stored in the above-described ROM 104, RAM 106, external storage device 108, or the like or downloaded via a network (a program defining the data collection method according to the present embodiment). By executing the above, the facility logging device 10 can function as various functional blocks or various steps described later. The processing that causes the CPU 101 to cause the computer that defines the data collection method according to the present embodiment to work on the computer is the same as the function and operation of the corresponding elements in the data collection system or method of the present embodiment.
　なお、設備ロギング装置１０について説明した上記ハードウェア構成は、センサロギング装置２０及びデータ処理装置３０にも同様に適用される。 Note that the hardware configuration described for the equipment logging device 10 is similarly applied to the sensor logging device 20 and the data processing device 30.
　図２に戻り、設備ロギング装置１０の制御部１１及び記憶部１２の詳細について説明する。設備ロギング装置１０の制御部１１は、設備選択部１１１と、トリガ設定部１１２と、通信部１１３とを備える。また、設備ロギング装置１０の記憶部１２は、ロギングデータ記憶部１２１と、トリガ設定記憶部１２２とを備える。 Referring back to FIG. 2, the details of the control unit 11 and the storage unit 12 of the equipment logging apparatus 10 will be described.

　設備選択部１１１は、例えば初期設定において、複数の設備４０から解析対象とするいずれか１つ以上の設備４０を選択する。この設備４０の選択は、作業者が設備ロギング装置１０の表示装置を介して入力装置を操作することによって行うことができる。 The facility selection unit 111 selects one or more facilities 40 to be analyzed from a plurality of facilities 40, for example, in the initial setting. The selection of the facility 40 can be performed by the operator operating the input device via the display device of the facility logging device 10.
　トリガ設定部１１２は、トリガ発生条件を満たす場合に、設備４０の制御装置４２に関するどのような特性のロギングデータを記録対象とするかを設定する。この場合、１つのトリガ発生条件について１つ又は複数の特性のロギングデータを設定することができる。トリガ設定部１１２によって設定されたトリガ情報はトリガ設定記憶部１２２に格納される。 The trigger setting unit 112 sets what characteristic logging data related to the control device 42 of the facility 40 is to be recorded when the trigger generation condition is satisfied. In this case, logging data having one or more characteristics can be set for one trigger generation condition. The trigger information set by the trigger setting unit 112 is stored in the trigger setting storage unit 122.
　通信部１１３は、データ処理装置３０との間でデータ通信する。通信部１１３は、例えば、設備４０の制御装置４２から取得したロギングデータをロギングデータ記憶部１２１から読み出し、このロギングデータをデータ処理装置３０へ送信する。また、通信部１１３は後述するトリガ信号をデータ処理装置３０へ送信する。 The communication unit 113 performs data communication with the data processing device 30. For example, the communication unit 113 reads the logging data acquired from the control device 42 of the facility 40 from the logging data storage unit 121 and transmits the logging data to the data processing device 30. In addition, the communication unit 113 transmits a trigger signal described later to the data processing device 30.
　次に、センサロギング装置２０の機能構成について説明する。センサロギング装置２０の機能構成は、設備ロギング装置１０とほぼ同様の内容を適用することができる。すなわち、センサロギング装置２０は、センサロギング装置２０のデータ収集に関わる動作全体を制御する制御部２１と、かかる動作に必要な情報を記憶するための記憶部２２とを有する。 Next, the functional configuration of the sensor logging device 20 will be described. The functional configuration of the sensor logging device 20 can apply almost the same contents as the facility logging device 10. That is, the sensor logging device 20 includes a control unit 21 that controls the entire operation related to data collection of the sensor logging device 20 and a storage unit 22 that stores information necessary for the operation.
　センサロギング装置２０の制御部２１は、センサ選択部２１１と、トリガ設定部２１２と、通信部２１３とを備える。また、センサロギング装置２０の記憶部２２は、ロギングデータ記憶部２２１と、トリガ設定記憶部２２２とを備える。 The control unit 21 of the sensor logging device 20 includes a sensor selection unit 211, a trigger setting unit 212, and a communication unit 213. The storage unit 22 of the sensor logging device 20 includes a logging data storage unit 221 and a trigger setting storage unit 222.
　センサ選択部２１１は、例えば初期設定において、複数のセンサ５０から解析対象とするいずれか１つ以上のセンサ５０を選択する。このセンサ５０の選択は、作業者がセンサロギング装置２０の表示装置を介して入力装置を操作することによって行うことができる。また、センサ選択部２１１は、必要に応じて、選択されたセンサ５０と、当該センサ５０が取り付けられた設備４０との通信を確立する設定も行う。 The sensor selection unit 211 selects any one or more sensors 50 to be analyzed from a plurality of sensors 50 in, for example, initial setting. The selection of the sensor 50 can be performed by the operator operating the input device via the display device of the sensor logging device 20. Moreover, the sensor selection part 211 performs the setting which establishes communication with the installation 40 to which the selected sensor 50 and the said sensor 50 were attached as needed.
　トリガ設定部２１２は、トリガ発生条件を満たす場合に、設備４０に取り付けられたセンサ５０に関するどのような特性のロギングデータを記録対象とするかを設定する。この場合、１つのトリガ発生条件について１つ又は複数の特性のロギングデータを設定することができる。トリガ設定部２１２によって設定されたトリガ情報はトリガ設定記憶部２２２に格納される。 The trigger setting unit 212 sets what characteristics of logging data related to the sensor 50 attached to the equipment 40 are to be recorded when the trigger generation condition is satisfied. In this case, logging data having one or more characteristics can be set for one trigger generation condition. The trigger information set by the trigger setting unit 212 is stored in the trigger setting storage unit 222.
　通信部２１３は、データ処理装置３０との間でデータ通信する。通信部２１３は、例えば、センサ５０から取得したロギングデータをロギングデータ記憶部２２１から読み出し、このロギングデータをデータ処理装置３０へ送信する。また、通信部２１３は後述するトリガ信号をデータ処理装置３０へ送信する。 The communication unit 213 performs data communication with the data processing device 30. For example, the communication unit 213 reads the logging data acquired from the sensor 50 from the logging data storage unit 221 and transmits the logging data to the data processing device 30. In addition, the communication unit 213 transmits a trigger signal described later to the data processing device 30.
　次に、データ処理装置３０の機能構成について説明する。データ処理装置３０は、データ処理装置３０のデータ収集に関わる動作全体を制御する制御部３１と、かかる動作に必要な情報を記憶するための記憶部３２とを有する。データ処理装置３０は、例えば、設備ロギング装置１０及びセンサロギング装置２０に対する上位装置に相当する。 Next, the functional configuration of the data processing device 30 will be described. The data processing device 30 includes a control unit 31 that controls the entire operation related to data collection of the data processing device 30, and a storage unit 32 that stores information necessary for the operation. The data processing device 30 corresponds to, for example, a host device for the equipment logging device 10 and the sensor logging device 20.
　データ処理装置３０の制御部３１は、トリガ発生条件設定部３１１と、トリガ信号処理部３１２と、データ収集部３１３と、時刻調整部３１４と、解析出力部３１５とを備える。また、データ処理装置３０の記憶部３２は、タグ情報記憶部３２１と、収集データ記憶部３２２とを備える。 The control unit 31 of the data processing device 30 includes a trigger generation condition setting unit 311, a trigger signal processing unit 312, a data collection unit 313, a time adjustment unit 314, and an analysis output unit 315. The storage unit 32 of the data processing device 30 includes a tag information storage unit 321 and a collected data storage unit 322.
　トリガ発生条件設定部３１１は、設備ロギング装置１０及びセンサロギング装置２０のいずれか一方のロギングデータを記録開始するためのトリガ発生条件を設定する。設備４０の機器４４がシリンダである場合、例えば、トリガ発生条件は、設備ロギング装置１０に対する「所定の時間間隔においてシリンダが動かなかった場合」という条件である。すなわち、この例では、トリガ発生条件は、設備４０の制御装置４２又はセンサ５０に対して所定の異常が発生したか否かである。この場合、トリガ信号は異常の有無を通知する信号であるため、トリガ信号は例えば１ビットデータである。 The trigger generation condition setting unit 311 sets a trigger generation condition for starting recording the logging data of either the equipment logging device 10 or the sensor logging device 20. When the equipment 44 of the equipment 40 is a cylinder, for example, the trigger generation condition is a condition “when the cylinder does not move in a predetermined time interval” for the equipment logging apparatus 10. That is, in this example, the trigger generation condition is whether or not a predetermined abnormality has occurred in the control device 42 or the sensor 50 of the facility 40. In this case, since the trigger signal is a signal notifying whether there is an abnormality, the trigger signal is, for example, 1-bit data.
　トリガ発生条件設定部３１１において設定された発生条件が満たされると、トリガ発生条件を満たしたことを示すトリガ信号が設備ロギング装置１０及びセンサロギング装置２０のいずれか一方のロギング装置の制御部において生成され、このトリガ信号がデータ処理装置３０に送信される。そして、データ処理装置３０では、トリガ信号処理部３１２がトリガ発生条件を満たしたことを示すトリガ信号を他方のロギング装置へ送信する。このようにトリガ信号処理部３１２は、設備ロギング装置１０及びセンサロギング装置２０のいずれか一方から受信したトリガ信号（トリガ発生条件を満たしたことを示す通知）を他方の装置へ送信する。これによって、設備ロギング装置１０、センサロギング装置２０及びデータ処理装置３０において、トリガ発生条件を満たしたことを契機とした各動作を連携して実行することができる。 When the generation condition set in the trigger generation condition setting unit 311 is satisfied, a trigger signal indicating that the trigger generation condition is satisfied is generated in the control unit of one of the equipment logging device 10 and the sensor logging device 20 Then, this trigger signal is transmitted to the data processing device 30. Then, in the data processing device 30, the trigger signal processing unit 312 transmits a trigger signal indicating that the trigger generation condition is satisfied to the other logging device. As described above, the trigger signal processing unit 312 transmits the trigger signal (notification indicating that the trigger generation condition is satisfied) received from one of the equipment logging device 10 and the sensor logging device 20 to the other device. Thereby, in the equipment logging apparatus 10, the sensor logging apparatus 20, and the data processing apparatus 30, each operation | movement triggered by satisfying the trigger generation condition can be executed in cooperation.
　なお、トリガ発生条件は、所定の異常が発生した場合に限らず、動作が正常な場合における条件であってもよい。例えば、トリガ発生条件は、データ処理装置３０からのデータ収集指示の有無、所定の時刻の到達、設備４０又はセンサ５０の稼働時間などの時間情報に基づく条件であってもよい。 Note that the trigger generation condition is not limited to a predetermined abnormality, but may be a condition when the operation is normal. For example, the trigger generation condition may be a condition based on time information such as presence / absence of a data collection instruction from the data processing device 30, arrival of a predetermined time, operating time of the facility 40 or the sensor 50.
　データ収集部３１３は、トリガ信号に応じて、設備ロギング装置１０が記録したロギングデータと、センサロギング装置２０が記録したロギングデータとを収集する。データ収集部３１３によって収集した各データは収集データ記憶部３２２に格納される。 The data collection unit 313 collects the logging data recorded by the facility logging device 10 and the logging data recorded by the sensor logging device 20 according to the trigger signal. Each data collected by the data collection unit 313 is stored in the collected data storage unit 322.
　ここで、データ処理装置３０は予めロギングデータの特性を示すタグ情報をタグ情報記憶部３２１に格納している。タグ情報記憶部３２１は、設備ロギング装置１０側のロギングデータについて、例えば、シリンダの回転（例えば回転数）、ソレノイドの動作（例えばオン／オフ）、シリンダの位置を検出するオートスイッチの動作（例えばオン／オフ）、サイクルタイムオーバーの発生有無などの特性を示すタグ情報を格納する。また、タグ情報記憶部３２１は、センサロギング装置２０側のロギングデータについて、例えば、シリンダの変位量などの特性を示すタグ情報を格納する。これらのタグ情報を予め格納することによって、設備ロギング装置１０及びセンサロギング装置２０からタグ情報及びロギングデータの両方を収集する必要がなくなり、特性を示すタグ情報を省略したロギングデータ（図５参照）を収集して解析することが可能となる。したがって、データ通信量を大幅に削減して通信速度を向上させることができる。 Here, the data processing device 30 stores tag information indicating the characteristics of logging data in the tag information storage unit 321 in advance. The tag information storage unit 321 includes, for example, cylinder rotation (for example, the number of rotations), solenoid operation (for example, on / off), and operation of an auto switch that detects the cylinder position (for example, for the logging data on the equipment logging device 10 side). ON / OFF) and tag information indicating characteristics such as the occurrence of cycle time over are stored. Further, the tag information storage unit 321 stores tag information indicating characteristics such as a cylinder displacement amount for the logging data on the sensor logging device 20 side. By storing these tag information in advance, there is no need to collect both tag information and logging data from the facility logging device 10 and the sensor logging device 20, and logging data that omits tag information indicating characteristics (see FIG. 5). Can be collected and analyzed. Therefore, it is possible to greatly reduce the amount of data communication and improve the communication speed.
　時刻調整部３１４は、設備ロギング装置１０とセンサロギング装置２０との間において各時刻を同期する又は同期した時刻を調整する。時刻調整部３１４は、例えば、ＮＴＰ（Ｎｅｔｗｏｒｋ　Ｔｉｍｅ　Ｐｒｏｔｏｃｏｌ）サーバを用いて、設備ロギング装置１０及びセンサロギング装置２０に対して各時刻を同期させる。また、時刻調整部３１４は、トリガ信号に基づいて、設備ロギング装置１０とセンサロギング装置２０との各時刻の同期を調整する。具体的には、設備ロギング装置１０との間及びセンサロギング装置２０との間において、トリガ信号に基づいて生成したアンサーバック信号の到達遅延時間を測定することによって、設備ロギング装置１０及びセンサロギング装置２０に対する同期時刻を調整する。この場合、データ処理装置３０がＮＴＰサーバを用いて設備ロギング装置１０及びセンサロギング装置２０に対して各時刻を同期させた後のさらなる調整を時刻調整部３１４で行う。そして、データ収集部３１３は、時刻調整部３１４によって調整された時刻に応じて設備ロギング装置１０及びセンサロギング装置２０からロギングデータを収集する。 The time adjustment unit 314 synchronizes each time between the equipment logging device 10 and the sensor logging device 20 or adjusts the synchronized time. The time adjustment unit 314 synchronizes each time with the facility logging device 10 and the sensor logging device 20 using, for example, an NTP (Network Time Protocol) server. Further, the time adjustment unit 314 adjusts the synchronization of the times of the facility logging device 10 and the sensor logging device 20 based on the trigger signal. Specifically, the equipment logging device 10 and the sensor logging device are measured by measuring the arrival delay time of the answer back signal generated based on the trigger signal between the equipment logging device 10 and the sensor logging device 20. The synchronization time for 20 is adjusted. In this case, the time adjustment unit 314 performs further adjustment after the data processing device 30 synchronizes each time with the facility logging device 10 and the sensor logging device 20 using the NTP server. The data collection unit 313 collects logging data from the facility logging device 10 and the sensor logging device 20 according to the time adjusted by the time adjustment unit 314.
　解析出力部３１５は、設備ロギング装置１０のロギングデータ、センサロギング装置２０のロギングデータ、及び、タグ情報記憶部３２１に格納されたタグ情報に基づいて解析情報を出力する。解析情報は例えば表示画面に表示される（図６参照）。 The analysis output unit 315 outputs analysis information based on the logging data of the facility logging device 10, the logging data of the sensor logging device 20, and the tag information stored in the tag information storage unit 321. The analysis information is displayed on a display screen, for example (see FIG. 6).

Next, a data collection method according to an embodiment of the present invention will be described with reference to FIGS. Here, FIG. 4 is a flowchart showing a procedure of the data collection method according to the present embodiment. FIG. 5 is a diagram illustrating the relationship between tag information and logging data. FIG. 6 is a diagram showing an example of a display screen for analysis information output based on logging data.
　本実施形態に係るデータ収集方法は、上記データ収集システム１を用いて行うことができる。本実施形態に係るデータ収集方法は、設備ロギング装置１０、センサロギング装置２０及びデータ処理装置３０の各装置のＣＰＵの制御に基づいて、各ＲＡＭにロードされたプログラムに規定された処理を実行することにより実現する。以下、トリガ発生条件が、設備ロギング装置１０において、機器４４であるシリンダが所定の時間間隔において動かなかった場合を例として説明する。なお、以下に説明する各工程は処理内容に矛盾を生じない範囲で任意に順番を変更して又は並列に実行することができる。 The data collection method according to the present embodiment can be performed using the data collection system 1 described above. The data collection method according to the present embodiment executes processing defined in a program loaded in each RAM based on the control of the CPUs of the equipment logging device 10, the sensor logging device 20, and the data processing device 30. This is realized. Hereinafter, the trigger generation condition will be described as an example in which the cylinder that is the device 44 does not move at a predetermined time interval in the equipment logging apparatus 10. In addition, each process demonstrated below can be arbitrarily changed in order in the range which does not produce contradiction in the processing content, or can be performed in parallel.
　データ収集の事前準備として、設備ロギング装置１０、センサロギング装置２０及びデータ処理装置３０の各装置において初期設定を行う。この初期設定は、ロギングデータを記録する対象となる設備４０及びセンサ５０を選択することを含む。具体的には、設備ロギング装置１０において設備選択部１１１が設備４０を選択し、また、センサロギング装置２０においてセンサ選択部２１１がセンサ５０を選択する。データ処理装置３０では、制御部３１が、設備ロギング装置１０によって選択された設備４０の中から解析対象となる設備４０を選択し、同様に、センサロギング装置２０によって選択されたセンサ５０の中から解析対象となるセンサ５０を選択する。 As an advance preparation for data collection, initial setting is performed in each of the equipment logging device 10, the sensor logging device 20, and the data processing device 30. This initial setting includes selecting the equipment 40 and the sensor 50 that are the targets for logging data. Specifically, the equipment selection unit 111 selects the equipment 40 in the equipment logging device 10, and the sensor selection unit 211 selects the sensor 50 in the sensor logging device 20. In the data processing device 30, the control unit 31 selects the facility 40 to be analyzed from the facilities 40 selected by the facility logging device 10, and similarly from the sensors 50 selected by the sensor logging device 20. The sensor 50 to be analyzed is selected.
　次に、データ処理装置３０のトリガ発生条件設定部３１１は、トリガ発生条件を設定する（Ｓ３０１）。具体的には、トリガ発生条件の対象として例えば設備ロギング装置１０を設定し、設備ロギング装置１０に対して「所定の時間間隔においてシリンダが動かなかった場合」という条件を設定する。トリガ発生条件は、作業者がデータ処理装置３０の表示装置を介して適宜設定することができる。 Next, the trigger generation condition setting unit 311 of the data processing device 30 sets a trigger generation condition (S301). Specifically, for example, the facility logging device 10 is set as a target of the trigger generation condition, and a condition “when the cylinder does not move at a predetermined time interval” is set for the facility logging device 10. The trigger generation condition can be appropriately set by the operator via the display device of the data processing device 30.
　そして、トリガ発生条件を設定した後又はそれと同時に、データ記録開始指示を設備ロギング装置１０及びセンサロギング装置２０の両方に対して行う（Ｓ３０２）。かかる指示を受けて、設備ロギング装置１０及びセンサロギング装置２０はそれぞれロギングデータの記録を開始する（Ｓ１０４及びＳ２０４）。具体的には、設備ロギング装置１０及びセンサロギング装置２０において、それぞれ、トリガ設定部１１２，２１２において設定されたトリガ発生条件に対応する特性のロギングデータの記録を開始する。例えば、設備ロギング装置１０では、シリンダの回転（例えば回転数）、ソレノイドの動作（例えばオン／オフ）、シリンダの位置を検出するオートスイッチの動作（例えばオン／オフ）、サイクルタイムオーバーの発生有無などの各特性に対応するロギングデータの記録を開始する。また、例えば、センサロギング装置２０では、シリンダの変位量などの特性に対応するロギングデータの記録を開始する。なお、記録されたロギングデータは、後述するステップ（Ｓ１１３，Ｓ２１３）において、必要な範囲でロギングデータ記憶部１２１，２２１に格納される。 Then, after setting the trigger generation condition or simultaneously with it, a data recording start instruction is given to both the facility logging device 10 and the sensor logging device 20 (S302). In response to such an instruction, the facility logging device 10 and the sensor logging device 20 each start recording logging data (S104 and S204). Specifically, in the facility logging device 10 and the sensor logging device 20, recording of logging data having characteristics corresponding to the trigger generation conditions set in the trigger setting units 112 and 212 is started. For example, in the equipment logging device 10, the rotation of the cylinder (for example, the number of rotations), the operation of the solenoid (for example, on / off), the operation of the auto switch for detecting the cylinder position (for example, on / off), the occurrence of cycle time over, etc. Recording of logging data corresponding to each characteristic is started. Further, for example, the sensor logging device 20 starts recording logging data corresponding to characteristics such as cylinder displacement. The recorded logging data is stored in the logging data storage units 121 and 221 within a necessary range in steps (S113 and S213) described later.
　このような状況において、設備ロギング装置１０においてトリガ発生（Ｓ１０５）を検出すると、設備ロギング装置１０の制御部１１がトリガ信号を生成する（Ｓ１０６）。ここで、トリガ信号の生成とは、トリガ信号の状態がオフ状態からオン状態に遷移することを意味する。 In such a situation, when the facility logging device 10 detects a trigger occurrence (S105), the control unit 11 of the facility logging device 10 generates a trigger signal (S106). Here, the generation of the trigger signal means that the state of the trigger signal transits from the off state to the on state.
　その後、設備ロギング装置１０の通信部１１３がトリガ信号をデータ処理装置３０へ送信し（Ｓ１０７）、データ処理装置３０では、トリガ信号処理部３１２がこのトリガ信号をセンサロギング装置２０へ送信する（Ｓ３０８）。このとき、データ処理装置３０は、センサロギング装置２０との間でアンサーバック信号を受け取り（Ｓ２０９）、アンサーバック信号の到達遅延時間に基づいてセンサロギング装置２０との間で時刻調整を行う。同様に設備ロギング装置１０との間においても、アンサーバック信号の送受信を行うことによって（Ｓ３１０，Ｓ１１１）、アンサーバック信号の到達遅延時間に基づいて設備ロギング装置１０との間で時刻調整を行う。これらの時刻調整はデータ処理装置３０の時刻調整部３１４が行う。こうして各装置の時刻が同期され又は同期後の時刻がさらに補正される。 Thereafter, the communication unit 113 of the equipment logging device 10 transmits a trigger signal to the data processing device 30 (S107). In the data processing device 30, the trigger signal processing unit 312 transmits this trigger signal to the sensor logging device 20 (S308). ). At this time, the data processing device 30 receives the answer back signal with the sensor logging device 20 (S209), and adjusts the time with the sensor logging device 20 based on the arrival delay time of the answer back signal. Similarly, by transmitting / receiving an answer back signal to / from the equipment logging device 10 (S310, S111), time adjustment is performed with the equipment logging device 10 based on the arrival delay time of the answer back signal. These time adjustments are performed by the time adjustment unit 314 of the data processing device 30. In this way, the time of each device is synchronized or the time after synchronization is further corrected.
　データ処理装置３０では、調整後の時刻に基づくトリガ発生時刻を記録する（Ｓ３１２）。そして、設備ロギング装置１０では、トリガ発生時刻に基づいて、トリガ発生時のロギングデータをロギングデータ記憶部１２１に格納する（Ｓ１１３）。同様に、センサロギング装置２０では、トリガ発生時刻に基づいて、トリガ発生時のロギングデータをロギングデータ記憶部２１２に格納する（Ｓ２１３）。ここで、トリガ発生時とは、トリガ発生時刻を含む前後の所定の時間間隔を含む。この時間間隔は、予め設備ロギング装置１０及びセンサロギング装置２０側で設定されていてもよいし、あるいは、データ処理装置３０側でロギングデータを収集するときに決めてもよい。 The data processing device 30 records the trigger occurrence time based on the adjusted time (S312). Then, the equipment logging device 10 stores the logging data at the time of trigger occurrence in the logging data storage unit 121 based on the trigger occurrence time (S113). Similarly, the sensor logging device 20 stores the logging data at the time of trigger occurrence in the logging data storage unit 212 based on the trigger occurrence time (S213). Here, the trigger occurrence time includes a predetermined time interval before and after the trigger occurrence time. This time interval may be set in advance on the equipment logging device 10 and the sensor logging device 20 side, or may be determined when logging data is collected on the data processing device 30 side.
　その後、設備ロギング装置１０では、ロギングデータ記憶部１２１に記憶されたロギングデータを読み出し、トリガ発生時のロギングデータをデータ処理装置３０へ送信する（Ｓ１１４）。また、同様に、センサロギング装置２０では、ロギングデータ記憶部２２１に記憶されたロギングデータを読み出し、トリガ発生時のロギングデータをデータ処理装置３０へ送信する（Ｓ２１４）。こうして、データ処理装置３０は、各ロギングデータを収集し（Ｓ３１５）、収集データ記憶部３２２に格納する。 Thereafter, the facility logging device 10 reads the logging data stored in the logging data storage unit 121 and transmits the logging data when the trigger is generated to the data processing device 30 (S114). Similarly, the sensor logging device 20 reads the logging data stored in the logging data storage unit 221 and transmits the logging data when the trigger is generated to the data processing device 30 (S214). Thus, the data processing apparatus 30 collects each logging data (S315) and stores it in the collected data storage unit 322.
　データ処理装置３０では、収集データ記憶部３２２及びタグ情報記憶部３２１に格納された各データに基づいて、図５に示すような、タグ情報及び時間情報を行列としたマトリクス情報のデータ表が生成される。この場合、データ処理装置３０が、設備ロギング装置１０及びセンサロギング装置２０からロギングデータを受信するときに、図５のマトリクス状に配列された各位置にデータの受信先を指定することによって、設備ロギング装置１０及びセンサロギング装置２０からロギングデータを受信するだけで図５に示すデータ表を生成することができる。言い換えれば、図５に示すデータ表を生成するときに設備ロギング装置１０及びセンサロギング装置２０からタグ情報（設備やセンサに関する情報を含む）や時刻情報を併せて受信することを省略することができる。 In the data processing device 30, based on the data stored in the collected data storage unit 322 and the tag information storage unit 321, a data table of matrix information using tag information and time information as a matrix is generated as shown in FIG. Is done. In this case, when the data processing device 30 receives the logging data from the equipment logging device 10 and the sensor logging device 20, the data processing device 30 designates the data receiving destination at each position arranged in the matrix form of FIG. The data table shown in FIG. 5 can be generated only by receiving logging data from the logging device 10 and the sensor logging device 20. In other words, when the data table shown in FIG. 5 is generated, it is possible to omit receiving tag information (including information about equipment and sensors) and time information from the equipment logging device 10 and the sensor logging device 20 together. .
　その後、データ処理装置３０の解析出力部３１５は、解析情報を表示装置などに出力する（Ｓ３１６）。例えば、解析出力部３１５は、ロギングデータ及びタグ情報を含む図５のデータ表に基づいて図６に示すような解析情報の表示画面３３０を出力する。図６に示す例では、表示画面３３０には、設備ロギング装置１０のロギングデータ（オートスイッチ、ソレノイド及びサイクルタイムオーバーの各特性に対応するロギングデータ）と、センサロギング装置２０のロギングデータ（変位計の特性に対応するロギングデータ）とが共通の時間軸に基づいて表示されている。この例によれば、シリンダが所定の時間間隔において動かなかったことが検知されたトリガ発生が、オートスイッチが故障により動作しなかったことが原因であることがわかる。 Thereafter, the analysis output unit 315 of the data processing device 30 outputs the analysis information to a display device or the like (S316). For example, the analysis output unit 315 outputs an analysis information display screen 330 as shown in FIG. 6 based on the data table of FIG. 5 including logging data and tag information. In the example shown in FIG. 6, the display screen 330 includes logging data of the equipment logging device 10 (logging data corresponding to the characteristics of the auto switch, solenoid, and cycle time over) and logging data of the sensor logging device 20 (displacement meter). Logging data corresponding to the characteristic) is displayed based on a common time axis. According to this example, it can be seen that the trigger that is detected that the cylinder did not move at a predetermined time interval is caused by the auto switch not operating due to a failure.
　以上のとおり、本実施形態では、設備４０に関するロギングデータを記録する設備ロギング装置１０と、センサ５０を介して設備４０に関するロギングデータを記録するセンサロギング装置２０と、設備ロギング装置１０及びセンサロギング装置２０に通信可能に接続されたデータ処理装置３０とを備え、データ処理装置３０は、ロギングデータの各特性を示すタグ情報を格納するタグ情報記憶部３２１と、ロギングデータの記録開始のためのトリガ発生条件を設定するトリガ発生条件設定部３１１と、トリガ発生条件を満たしたことを示すトリガ信号を設備ロギング装置１０及びセンサロギング装置２０のいずれか一方のロギング装置から受信し、トリガ信号を他方のロギング装置へ送信するトリガ信号処理部３１２と、トリガ信号に応じて、設備ロギング装置１０及びセンサロギング装置２０から各ロギングデータを収集するデータ収集部３１３とを含む。 As described above, in this embodiment, the equipment logging device 10 that records logging data related to the equipment 40, the sensor logging device 20 that records logging data related to the equipment 40 via the sensor 50, the equipment logging device 10 and the sensor logging device. 20, a data processing device 30 connected to be communicable, the data processing device 30 including a tag information storage unit 321 for storing tag information indicating each characteristic of logging data, and a trigger for starting recording of logging data A trigger generation condition setting unit 311 for setting the generation condition, and a trigger signal indicating that the trigger generation condition is satisfied are received from one of the logging devices of the equipment logging device 10 and the sensor logging device 20, and the trigger signal is received from the other Trigger signal processing unit 312 to be sent to the logging device and the trigger signal Te, and a data collection unit 313 for collecting the logging data from the facility logging device 10 and sensor logging device 20.
　本実施形態に係るデータ処理装置及びデータ処理方法によれば、データ処理装置３０にはロギングデータの特性を示すタグ情報が格納されており、データ処理装置３０が、トリガ信号に応じて、各ロギング装置１０，２０からタグ情報の特性に対応するロギングデータを収集する。このため、共通の時間軸に基づいて各装置間にわたる複数の特性に対応するロギングデータの解析を行うことができる。また、タグ情報がデータ処理装置３０に格納されているため、ロギング装置１０，２０からのデータ通信量を削減してデータ通信速度の向上を図ることができる。したがって、設備４０の状態を迅速かつ正確に把握することができる。 According to the data processing device and the data processing method according to the present embodiment, tag information indicating the characteristics of logging data is stored in the data processing device 30, and the data processing device 30 performs each logging according to the trigger signal. Logging data corresponding to the characteristics of the tag information is collected from the devices 10 and 20. For this reason, it is possible to analyze the logging data corresponding to a plurality of characteristics across the apparatuses based on the common time axis. Further, since the tag information is stored in the data processing device 30, it is possible to reduce the amount of data communication from the logging devices 10 and 20 and improve the data communication speed. Therefore, the state of the facility 40 can be grasped quickly and accurately.
　本実施形態では、設備ロギング装置１０は、設備４０を制御する制御装置４２からロギングデータを取得することができる。また、センサロギング装置２０は、設備４０に取り付けられたセンサ５０からロギングデータを取得することができる。これによれば、設備４０の制御装置４２に関する特性と、設備４０の制御状態を検出するセンサ５０に関する特性との両方を含む層別の分析を行うことができる。 In this embodiment, the facility logging device 10 can acquire logging data from the control device 42 that controls the facility 40. The sensor logging device 20 can acquire logging data from the sensor 50 attached to the facility 40. According to this, the analysis according to the layer including both the characteristic regarding the control device 42 of the facility 40 and the characteristic regarding the sensor 50 that detects the control state of the facility 40 can be performed.

According to this, the logging data between the devices can be analyzed based on the accurately adjusted common time.

According to this, it is possible to perform a layered analysis between the apparatuses.
