Description

クレーン装置、及びクレーン制御システムCrane equipment and crane control system
　本発明はクレーン装置、及びクレーン制御システムに係り、特に外部の情報機器と稼動情報等を送受信するクレーン装置、及びクレーン制御システムに関するものである。 The present invention relates to a crane device and a crane control system, and particularly relates to a crane device and a crane control system that transmit and receive operation information, etc. to and from external information equipment.
　例えば、工場等の建屋内には、製造された構造部品等の吊荷を鉛直方向に移動させる巻上用電動機、及び吊り下げた吊荷を天井側に設置されたレールに沿って移動させる移動用電動機を装備したクレーン装置が設置されている。 For example, inside a building such as a factory, there is a hoisting motor that moves suspended loads such as manufactured structural parts in the vertical direction, and a hoisting motor that moves suspended loads along rails installed on the ceiling side. A crane device equipped with an electric motor is installed.
　巻上用電動機は建屋の天井に沿って敷設されたレールに沿って走行されるもので、巻上用電動機にはワイヤロープを巻き付けるロープドラムを備えている。このロープドラムは、巻上用電動機によって回転させられ、吊荷に連結されたワイヤロープを巻き取り、繰り出す機能を備えている。 The hoisting motor runs along a rail laid along the ceiling of the building, and is equipped with a rope drum around which a wire rope is wound. This rope drum is rotated by a hoisting electric motor, and has the function of winding up and letting out the wire rope connected to the suspended load.
　また、クレーン装置には、レール上を走行させるための移動用電動機が備えられており、この移動用電動機を駆動することにより、レールに沿って巻上用電動機が移動される。尚、以下では、巻上用電動機、移動用電動機の一方、或いは両方を、駆動用電動機とまとめて表記する場合もある。 Furthermore, the crane device is equipped with a moving electric motor for traveling on the rails, and by driving this moving electric motor, the hoisting electric motor is moved along the rails. Note that, hereinafter, one or both of the hoisting motor and the moving motor may be collectively referred to as the driving motor.
　このようなクレーン装置においては、クレーン装置の稼動状況を把握して保守、管理を行うことが必要である。ところで、巻上用や移動用の駆動用電動機は、主に工場の天井に設置されており、その制御部も駆動用電動機と一体となっているのが一般的である。点検やトラブル対応等の保守、管理で、駆動用電動機の稼動情報を確認する場合、駆動用電動機の設置場所である天井に保守管理作業者が登る必要がある。このため、駆動用電動機の設置場所によっては、高所作業車を準備するなど、安全性の確保に時間を要することになる。 In such a crane device, it is necessary to understand the operating status of the crane device and perform maintenance and management. Incidentally, the drive motor for hoisting and moving is mainly installed on the ceiling of a factory, and its control section is also generally integrated with the drive motor. When confirming operating information of the drive motor for maintenance and management such as inspection and troubleshooting, a maintenance worker needs to climb up to the ceiling where the drive motor is installed. For this reason, depending on the installation location of the drive electric motor, it may take time to ensure safety, such as preparing an aerial work vehicle.
　このような問題を解決するために、例えば特開２０１４－３４２６０号公報（特許文献１）に記載されたクレーン管理システムが知られている。特許文献１では、駆動用電動機に設けた第１の情報処理装置で稼動情報を取得し、第1の制御装置の近傍に持ち運ばれた可搬型の第２の情報処理装置へ、収集した稼動情報を送信することで、駆動用電動機の設置場所である天井まで登らなくても、駆動用電動機の近傍の床面から、駆動用電動機の稼動情報を確認することができる。 In order to solve such problems, a crane management system described in, for example, Japanese Unexamined Patent Publication No. 2014-34260 (Patent Document 1) is known. In Patent Document 1, operating information is acquired by a first information processing device provided in a drive electric motor, and the collected operating information is transferred to a portable second information processing device carried near the first control device. By transmitting the information, the operating information of the drive motor can be confirmed from the floor near the drive motor without having to climb up to the ceiling where the drive motor is installed.
　この特許文献１のクレーン管理システムにおいては、クレーン装置には巻上用、横行用、走行用のそれぞれの用途に応じた動作制御が可能な第１の情報処理装置が取り付けられており、第２の情報処理装置は、第１の情報処理装置の動作に関する情報の送信を第１の情報処理装置に対して要求し、この要求に応じて第１の情報処理装置から送信されてきた情報を受信すると共に、受信した情報をクレーン装置の動作情報として関連付けて自己の記憶手段に記憶する構成とされている。更に、第２の情報制御装置は、クラウドサーバ等の第３の制御装置と通信可能に設定する構成も可能とされている。 In the crane management system of Patent Document 1, a first information processing device is attached to the crane device, which is capable of controlling operations according to hoisting, traversing, and traveling purposes, and a second information processing device is attached to the crane device. The information processing device requests the first information processing device to transmit information regarding the operation of the first information processing device, and receives the information transmitted from the first information processing device in response to this request. At the same time, the received information is associated with the operation information of the crane device and stored in its own storage means. Furthermore, the second information control device can also be configured to be able to communicate with a third control device such as a cloud server.

　ところで、特許文献１においては、第１の情報処理装置と第２の制御装置は、Ｗｉ－Ｆｉ（登録商標）やＢｌｕｅｔｏｏｔｈ（登録商標）といった近距離通信が可能な無線通信モジュールを搭載した通信機器を備えている。このため、第１の情報処理装置が送信する電波が届く範囲に、第２の情報処理装置を持ち運ばないと、各種の情報を収集することができない。例えば、第２の情報処理装置に搭載されている、クレーン装置の構成部品の残存寿命の演算を常時行うことができなく、クレーン装置の構成部品の寿命が経過した状態を見逃す恐れがある。 By the way, in Patent Document 1, the first information processing device and the second control device are communication devices equipped with a wireless communication module capable of short-range communication such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). It is equipped with Therefore, unless the second information processing device is carried within the reach of the radio waves transmitted by the first information processing device, various types of information cannot be collected. For example, it is not possible to constantly calculate the remaining life of the components of the crane device mounted on the second information processing device, and there is a risk of overlooking the state where the life of the component of the crane device has passed.
　また、第３の情報処理装置としてのクラウド等のデータサーバとインターネット通信によって通信を行なうことができるが、第３の情報処理装置は、第２の情報処理装置とのみ通信できる構成なので、第２の情報処理装置が、第１の情報処理装置から稼動情報を取得しないと、第３の情報処理装置に最新情報を送ることができず、第３の情報処理装置が最新の稼動情報を逐次取得できないという課題がある。 Further, it is possible to communicate with a data server such as a cloud as a third information processing device via Internet communication, but since the third information processing device is configured to be able to communicate only with the second information processing device, the second information processing device If the information processing device does not acquire the operating information from the first information processing device, it cannot send the latest information to the third information processing device, and the third information processing device sequentially acquires the latest operating information. The problem is that it cannot be done.
　例えば、上述のデータサーバの側で残存寿命の演算を行うにしても、第２の情報処理装置を第１の情報処理装置が送信する電波が届く範囲に、第２の情報処理装置を持ち運ばないと、残存寿命の演算を行うことができない。 For example, even if the remaining life is calculated on the data server side described above, if the second information processing device is carried within the range where the radio waves transmitted by the first information processing device can reach. Otherwise, the remaining life cannot be calculated.

　以下、本発明の実施形態について図面を用いて詳細に説明するが、本発明は以下の実施形態に限定されることなく、本発明の技術的な概念の中で種々の変形例や応用例をもその範囲に含むものである。 Hereinafter, embodiments of the present invention will be described in detail using drawings, but the present invention is not limited to the following embodiments, and various modifications and applications can be made within the technical concept of the present invention. is also included within the scope.
　図１は本発明が適用されるインバータ式クレーン装置の全体構成を示し、図２は本発明の実施形態になるクレーン制御システムの構成を示している。 FIG. 1 shows the overall configuration of an inverter type crane device to which the present invention is applied, and FIG. 2 shows the configuration of a crane control system according to an embodiment of the present invention.
　図１において、インバータ式クレーン装置は、クレーンフック１、ワイヤロープ２、巻上誘導電動機３、巻上用ドラム４、横行誘導電動機５、横行用車輪６、横行用ガーダ７、走行誘導電動機８、走行用車輪９、走行用ガーダ１０、巻上・横行インバータ制御装置１１、ケーブルに吊り下げられた操作入力装置１２、走行用インバータ制御装置１３等から構成されている。また、巻上誘導電動機３、横行誘導電動機５、及び走行誘導電動機８には、誘導電動機用ブレーキ１４(図２参照)が各々に内蔵されている。 In FIG. 1, the inverter crane device includes a crane hook 1, a wire rope 2, a hoisting induction motor 3, a hoisting drum 4, a traversing induction motor 5, traversing wheels 6, a traversing girder 7, a traversing induction motor 8, It is composed of running wheels 9, a running girder 10, a hoisting/traversing inverter control device 11, an operation input device 12 suspended from a cable, a running inverter control device 13, and the like. Further, the hoisting induction motor 3, the traversing induction motor 5, and the traveling induction motor 8 each have a built-in induction motor brake 14 (see FIG. 2).
　インバータ式クレーン装置は、クレーンフック１に取り付けた吊荷を、巻上誘導電動機３によって回転する巻上用ドラム４により、ワイヤロープ２を巻き上げ/巻き下げすることで鉛直方向(Ｙ方向、-Ｙ方向の矢印で示す)、即ち上下方向に吊荷を移動する。また、横行用車輪６を横行誘導電動機５が回転させ、横行用ガーダ７に沿って左右方向(Ｘ方向、-Ｘ方向の矢印で示す)に移動する。更に、走行用車輪９を走行誘導電動機８が回転させ、走行用ガーダ１０に沿って前後方向(Ｚ方向、-Ｚ方向の矢印で示す)に移動する。 The inverter type crane device hoists a suspended load attached to a crane hook 1 in a vertical direction (Y direction, -Y direction, (indicated by the direction arrow), that is, move the suspended load in the vertical direction. Further, the traversing wheel 6 is rotated by the traversing induction motor 5, and moves along the traversing girder 7 in the left-right direction (indicated by arrows in the X direction and -X direction). Furthermore, the traveling induction motor 8 rotates the traveling wheels 9, and the wheels 9 move in the front-rear direction (indicated by arrows in the Z direction and -Z direction) along the traveling girder 10.
　図２に示すように、巻上・横行インバータ制御装置１１は、巻上・横行インバータ制御部１５、巻上用インバータ１６、横行用インバータ１７が内蔵されている。また、走行用インバータ制御装置１３には、走行インバータ制御部１８、及び走行用インバータ１９が内蔵されている。また、巻上・横行インバータ制御部１５と走行インバータ制御部１８とは通信線（有線）２０によって接続されている。 As shown in FIG. 2, the hoisting/traversing inverter control device 11 includes a hoisting/traversing inverter control section 15, a hoisting inverter 16, and a traversing inverter 17. Further, the running inverter control device 13 includes a running inverter control section 18 and a running inverter 19 built therein. Further, the hoisting/traversing inverter control section 15 and the traveling inverter control section 18 are connected by a communication line (wired) 20.
　巻上誘導電動機３と横行誘導電動機５は、巻上・横行用インバータ制御装置１１に格納された巻上・横行インバータ制御部１５により制御される。即ち、オペレータが操作入力装置１２から所定の指示を入力すると、巻上・横行インバータ制御部１５は、巻上用インバータ１６と横行用インバータ１７を制御するため、巻上用インバータ１６と横行用インバータ１７に制御に必要な動作情報を与える。尚、巻上誘導電動機３には、エンコーダ２１が取り付けられており、巻上誘導電動機３の回転情報を巻上・横行インバータ制御部１５に入力している。 The hoisting induction motor 3 and the traversing induction motor 5 are controlled by a hoisting/traversing inverter control section 15 stored in a hoisting/traversing inverter control device 11. That is, when the operator inputs a predetermined instruction from the operation input device 12, the hoisting/traversing inverter control unit 15 controls the hoisting inverter 16 and the traversing inverter 17 in order to control the hoisting inverter 16 and the traversing inverter 17. 17 is given operational information necessary for control. An encoder 21 is attached to the hoisting induction motor 3 and inputs rotation information of the hoisting induction motor 3 to the hoisting/traversing inverter control section 15.
　そして、巻上用インバータ１６と横行用インバータ１７は、巻上誘導電動機３と横行誘導電動機５に必要な周波数、電圧、電流を加え、同時に誘導電動機用ブレーキ１４を開放制御する。これによって、巻上用ドラム４の場合、クレーンフック１に取り付けられた吊荷が、落下することなく鉛直方向に移動させられ、また、横行用車輪６の場合、横行用ガーダ７に沿って横行用車輪６を左右方向に移動させる。 Then, the hoisting inverter 16 and the traversing inverter 17 apply the necessary frequency, voltage, and current to the hoisting induction motor 3 and the traversing induction motor 5, and simultaneously control the induction motor brake 14 to open. As a result, in the case of the hoisting drum 4, the suspended load attached to the crane hook 1 is moved in the vertical direction without falling, and in the case of the traverse wheels 6, it is moved traversely along the traverse girder 7. The wheels 6 are moved in the left and right direction.
　同様に走行用車輪９に取り付けてある走行誘導電動機８は、オペレータが操作入力装置１２からの所定の指示を入力すると、走行用インバータ制御装置１３に格納された走行インバータ制御部１８が走行用インバータ１９を制御し、走行用インバータ１９は走行誘導電動機８に必要な周波数、電圧、電流を加え、同時に誘導電動機用ブレーキ１４を開放制御することで、走行用ガーダ１０に沿って走行用車輪９を前後方向に移動させる。 Similarly, when the operator inputs a predetermined instruction from the operation input device 12, the running induction motor 8 attached to the running wheel 9 switches the running inverter control unit 18 stored in the running inverter control device 13 to 19, the running inverter 19 applies the necessary frequency, voltage, and current to the running induction motor 8, and at the same time controls the induction motor brake 14 to open, thereby moving the running wheels 9 along the running girder 10. Move it back and forth.
　更に巻上・横行インバータ制御装置１５には無線通信部２２が設けられており、この無線通信部２２は、通信線２３によって巻上・横行インバータ制御部１５と接続されている。また、走行インバータ制御部１９は通信線２０によって巻上・横行インバータ制御装置１５に接続されている。したがって、走行インバータ制御部１９、巻上・横行インバータ制御装置１５におけるクレーン装置の稼動情報や、電動機の稼動情報（電流値や電流瞬時値等の動作情報）は無線通信部２２に送られることになる。 Further, the hoisting/traversing inverter control device 15 is provided with a wireless communication section 22, and this wireless communication section 22 is connected to the hoisting/traversing inverter control section 15 via a communication line 23. Further, the traveling inverter control section 19 is connected to the hoisting/traversing inverter control device 15 via a communication line 20. Therefore, the operation information of the crane device and the operation information of the electric motor (operation information such as current value and instantaneous current value) in the traveling inverter control unit 19 and the hoisting/traversing inverter control unit 15 are sent to the wireless communication unit 22. Become.
　無線通信部２２は、遠距離（遠隔）通信を行う遠距離通信部と、近距離通信を行う近距離通信部を備えており、定期的にクラウドサーバ２４と通信を実行し、必要に応じて可搬型の情報表示端末２６からの要請で情報表示端末２６と通信を実行する。また、無線通信部２２は遠距離通信を行う通信アンテナ２２Ｌと近距離通信を行なう通信アンテナ２２Ｓとが備えられている。 The wireless communication unit 22 includes a long-distance communication unit that performs long-distance (remote) communication and a short-range communication unit that performs short-range communication, and periodically communicates with the cloud server 24 and performs communication as necessary. Communication with the information display terminal 26 is executed in response to a request from the portable information display terminal 26. Furthermore, the wireless communication unit 22 is equipped with a communication antenna 22L for long-distance communication and a communication antenna 22S for short-range communication.
　無線通信部２２は遠距離通信網によって、演算機能を備えるデータサーバから構成されたクラウドサーバ２４の通信部２５の通信アンテナ２５Ａに対して双方向で接続されている。また、このクラウドサーバ２４の通信アンテナ２５Ａは、通信部を備えた可搬型の情報表示端末２６とも遠距離通信網で接続されている。更に、無線通信部２２は、近距離通信網によって、可搬型の情報表示端末２６に対して双方向で接続されている。情報表示端末２５の通信部２７は、遠距離通信を行う通信アンテナ２７Ｌと近距離通信を行なう通信アンテナ２７Ｓとが備えられている。 The wireless communication unit 22 is bidirectionally connected to the communication antenna 25A of the communication unit 25 of the cloud server 24, which is composed of a data server with arithmetic functions, via a long-distance communication network. The communication antenna 25A of the cloud server 24 is also connected to a portable information display terminal 26 equipped with a communication unit via a long-distance communication network. Furthermore, the wireless communication unit 22 is bidirectionally connected to a portable information display terminal 26 via a short-range communication network. The communication unit 27 of the information display terminal 25 is equipped with a communication antenna 27L for long-distance communication and a communication antenna 27S for short-range communication.
　遠距離通信網としては、インターネット通信網、電話回線通信網、及びこれらを組み合わせた通信網を使用することができる。また、近距離通信網としては、Ｗｉ－Ｆｉ通信網やＢｌｕｅｔｏｏｔｈ通信網を使用することができる。 As the long-distance communication network, an Internet communication network, a telephone line communication network, and a communication network combining these can be used. Further, as the short-range communication network, a Wi-Fi communication network or a Bluetooth communication network can be used.
　次に、クレーン装置の巻上・横行インバータ制御部１５と、クラウドサーバ２４と、情報表示端末２５との稼動情報等の流れについて、簡略化した図３、図４に基づいて説明を加える。図３と図４は実質的に同じ構成であるが、異なるのは走行インバータ制御部１８が、無線通信部２２と直接的に通信線２０で接続されている点である。このため、以下では図３を用いて説明を進める。 Next, the flow of operation information, etc. between the hoisting/traversing inverter control unit 15 of the crane device, the cloud server 24, and the information display terminal 25 will be explained based on simplified FIGS. 3 and 4. 3 and 4 have substantially the same configuration, but the difference is that the running inverter control section 18 is directly connected to the wireless communication section 22 via the communication line 20. Therefore, the explanation will be made below using FIG. 3.
　図３において、クラウドサーバ２４の通信部２５は、特許文献1に示されている管理システムとは異なり、巻上・横行インバータ装置１５や走行インバータ制御部１８が設置されている工場に赴くことなく、工場とは離れた遠隔地に設置されているクラウドサーバ２４でクレーン装置の稼動情報を取得することができる。 In FIG. 3, unlike the management system shown in Patent Document 1, the communication unit 25 of the cloud server 24 can be operated without going to the factory where the hoisting/traversing inverter device 15 and the traveling inverter control unit 18 are installed. , operation information of the crane device can be acquired from the cloud server 24 installed in a remote location away from the factory.
　クラウドサーバ２４は、所定時間毎に定期的にクレーン装置の最新の稼動情報を取得して記憶部（図示せず）に更新、記憶する機能を備えている。更には、編集機能をも備えており、グラフ等の作成を行うことができる。このように、クラウドサーバ２４は、クレーン装置の最新の稼動情報を保持することが可能となる。 The cloud server 24 has a function of periodically acquiring the latest operation information of the crane device at predetermined time intervals, and updating and storing it in a storage unit (not shown). It also has an editing function, allowing you to create graphs, etc. In this way, the cloud server 24 can hold the latest operating information of the crane device.
　クレーン装置の側の無線通信部２２とクラウドサーバ２４の側の通信部２５とは、遠距離通信網２８で通信が行われる。遠距離通信網としては、上述の通りインターネット通信網、電話回線通信網、及びこれらを組み合わせた通信網を使用することができる。尚、これ以外の遠距離通信ができる通信網を使用することも可能である。 The wireless communication unit 22 on the crane device side and the communication unit 25 on the cloud server 24 side communicate with each other via the long distance communication network 28. As the long-distance communication network, as described above, an Internet communication network, a telephone line communication network, and a communication network combining these can be used. Note that it is also possible to use other communication networks capable of long-distance communication.
　情報表示端末２７は２系統の通信機能を備えており、1つは遠距離通信網２８であり、この通信網は、インターネット通信網、電話回線通信網、及びこれらを組み合わせた通信網を使用することができる。もう1つの通信網は、近距離通信網２９であり、Ｗｉ－Ｆｉ通信網やＢｌｕｅｔｏｏｔｈ通信網を使用することができる。 The information display terminal 27 has two communication functions, one of which is a long-distance communication network 28, which uses an Internet communication network, a telephone line communication network, and a communication network that is a combination of these. be able to. Another communication network is a short-range communication network 29, which can use a Wi-Fi communication network or a Bluetooth communication network.
　近距離通信網２９は、保守管理作業者が情報表示端末２６をクレーン装置まで持ち運ぶことによって、通信を確立することができる。尚、この近距離通信網２９は通信費用が発生しないので、多量の稼動情報を送信するのに適している。また、直接的に情報表示端末２６で表示させる稼動情報を伝送することができる。情報表示端末２６としては、タブレット端末や、スマートフォン、パーソナルコンピュータ等を使用することができる。 Communication can be established using the short-range communication network 29 by a maintenance worker carrying the information display terminal 26 to the crane device. Note that this short-range communication network 29 does not incur communication costs, so it is suitable for transmitting a large amount of operating information. Further, operating information to be displayed on the information display terminal 26 can be directly transmitted. As the information display terminal 26, a tablet terminal, a smartphone, a personal computer, etc. can be used.
　以上において、クレーン装置の稼動情報は巻上・横行インバータ制御部１５や走行インバータ制御部１８で取得される。取得した稼動情報は、図３に示すように有線の通信線２３により、無線通信部２１へ送信される。ここで、走行インバータ制御部１８で取得した稼動情報は、有線の通信線２０を介し、巻上・横行インバータ制御部１５へ送信しても良いし、図４に示すように、直接的に無線通信部２２へ送信しても良い。 In the above, the operation information of the crane device is acquired by the hoisting/traversing inverter control section 15 and the traveling inverter control section 18. The acquired operating information is transmitted to the wireless communication section 21 via a wired communication line 23, as shown in FIG. Here, the operating information acquired by the traveling inverter control section 18 may be transmitted to the hoisting/traversing inverter control section 15 via a wired communication line 20, or directly wirelessly as shown in FIG. It may also be transmitted to the communication section 22.
　無線通信部２２は、取得した稼動情報を遠隔通信網２８でクラウドサーバ２４へ送信される。ここで、稼動情報は、クレーン装置の稼働時間、クレーン装置の稼動回数、クレーン装置のエラー情報等のような比較的長い時間間隔でサンプリングされる稼動情報であり、これらは所定時間毎に定期的にクラウドサーバ２４に送信される。尚、これらの稼動情報は、単位時間当たりの情報量としては少ないものであり、遠距離通信網２８の通信費用を低く抑えることができる。 The wireless communication unit 22 transmits the acquired operating information to the cloud server 24 via the remote communication network 28. Here, the operation information is operation information that is sampled at relatively long time intervals, such as the operation time of the crane device, the number of times the crane device is operated, error information of the crane device, etc., and these are periodically sampled at predetermined intervals. is sent to the cloud server 24. Note that the amount of information per unit time of these operating information is small, and the communication cost of the long-distance communication network 28 can be kept low.
　クラウドサーバ２４は、受信した稼動情報を保存すると共に、稼動情報から表示用の画面データやグラフデータを編集、作成することができる。そして、クラウドサーバ２４で作成された画面データやグラフデータは、保守管理作業者の情報表示端末２６からの要求によって、遠距離通信網２８を介して情報表示端末２６に送信される。 The cloud server 24 can save the received operating information and edit and create screen data and graph data for display from the operating information. The screen data and graph data created by the cloud server 24 are then transmitted to the information display terminal 26 via the long-distance communication network 28 in response to a request from the information display terminal 26 of a maintenance worker.
　情報表示端末２６においては、受診された画面データやグラフデータを保守管理作業者が閲覧できるように、情報表示端末２６の表示画面に表示する。また、例えば、クレーン装置の仕様などを情報表示端末２６で編集し、遠距離通信網２８を介して、この編集情報をクラウドサーバ２４へ送信して保存することもできる。 The information display terminal 26 displays the screen data and graph data of the patient on the display screen of the information display terminal 26 so that the maintenance worker can view the screen data and graph data. Furthermore, for example, specifications of the crane device and the like can be edited using the information display terminal 26, and this edited information can be transmitted to the cloud server 24 and stored via the long-distance communication network 28.
　一方、稼動情報として運転時の電動機の電流値等の動作瞬時値は、保守、管理を行う上で、保守管理作業者がオンラインで必要に応じて把握したい情報である。仮に、特許文献1のように、クレーン装置から遠距離通信網２８を介してクラウドサーバ２４に電動機の動作瞬時値を送信し、更にクラウドサーバ２４から遠距離通信網２８を介して情報表示端末２６に送信する場合、無線通信部２２とクラウドサー２４の間の通信頻度を上げるか、動作瞬時値を無線通信部２１に蓄積させ、ある程度まとめてクラウドサーバ２４へ送信することが考えられる。しかしながら、このような方法だと通信で送る情報量が大きくなり、情報の即時性の低下や通信費用が高騰するという課題を生じる。 On the other hand, instantaneous operating values such as the current value of the motor during operation are information that a maintenance worker would like to grasp online as needed when performing maintenance and management as operating information. Suppose, as in Patent Document 1, the instantaneous operating value of the motor is transmitted from the crane device to the cloud server 24 via the long-distance communication network 28, and further from the cloud server 24 via the long-distance communication network 28 to the information display terminal 26. When transmitting to the cloud server 24, it is possible to increase the communication frequency between the wireless communication unit 22 and the cloud server 24, or to accumulate the instantaneous operation values in the wireless communication unit 21 and transmit them to the cloud server 24 in a certain amount. However, such a method increases the amount of information sent via communication, resulting in problems such as a decrease in the immediacy of the information and a rise in communication costs.
　そこで、情報表示端末２６とクレーン装置の無線通信部２２とを、Ｗｉ－Ｆｉ通信網やＢｌｕｅｔｏｏｔｈ通信網等の近距離通信網２９で接続し、上述の動作瞬時値については、情報表示端末２６からの要請に応じて直接的に情報表示端末２６へ送信する構成とされている。これによって、情報の即時性の低下や通信費用の高騰といった課題を解決することができる。 Therefore, the information display terminal 26 and the wireless communication section 22 of the crane device are connected via a short-distance communication network 29 such as a Wi-Fi communication network or a Bluetooth communication network, and the above-mentioned instantaneous operating values are transmitted from the information display terminal 26. The configuration is such that the information is directly transmitted to the information display terminal 26 in response to a request. This makes it possible to solve problems such as a decrease in the immediacy of information and a rise in communication costs.
　ここで、情報表示端末２６が近距離通信網２９で接続するクレーン装置側の無線通信部２２の選択は、情報表示端末２６の側で設定しても良いし、クラウドサーバ２４から遠隔通信網２８で取得した切換情報から設定しても良い。 Here, the selection of the wireless communication unit 22 on the crane device side to which the information display terminal 26 connects via the short-range communication network 29 may be set on the information display terminal 26 side, or may be set from the cloud server 24 to the remote communication network 29. The settings may be made from the switching information obtained in .
　このように、本実施形態によれば、クレーン装置の稼動情報を遠距離通信で、定期的にデータサーバに送信して稼動情報をデータサーバに蓄積、更新し、更に近距離通信で、情報表示端末２６からの要請に応じて情報表示端末に送信して必要に応じて稼動情報を閲覧できる。 As described above, according to the present embodiment, the operating information of the crane device is periodically transmitted to the data server via long-distance communication, the operating information is stored and updated in the data server, and the information is further displayed via short-range communication. In response to a request from the terminal 26, the operational information can be transmitted to the information display terminal and viewed as necessary.
　これによれば、クレーン装置の最新の稼動情報をデータサーバに定期的に蓄積可能となり、クレーン装置の稼働状態を常時監視することができるので、遠隔での監視を精度良く実施することができ、更に電動機の電流値の動作瞬時値のような情報量が多い動作情報を、必要に応じて可搬型の情報表示端末で閲覧でき、情報の即時性を向上すると共に、通信費用を可及的に低減できるという効果を奏する。 According to this, the latest operating information of the crane equipment can be stored regularly in the data server, and the operating status of the crane equipment can be constantly monitored, so remote monitoring can be carried out with high precision. Furthermore, operation information with a large amount of information, such as the instantaneous operation value of the electric motor's current value, can be viewed on a portable information display terminal as needed, improving the immediacy of information and reducing communication costs as much as possible. This has the effect that it can be reduced.
　以上の説明は、個々のクレーン装置に外部の情報機器を接続する形態であったが、複数のクレーン装置をまとめて外部の情報機器と接続することも可能である。この方法だと通信費用を総合的に低く抑えることが可能となる。以下その具体例を説明する。 Although the above explanation has been about the form in which external information equipment is connected to each crane device, it is also possible to connect a plurality of crane devices together to external information equipment. This method makes it possible to keep communication costs low overall. A specific example will be explained below.
　図５において、図２に示す巻上・横行インバータ制御装置１１と走行用インバータ制御装置１３からなるクレーン制御部３０は、Ｗｉ－Ｆｉ通信網やＢｌｕｅｔｏｏｔｈ通信網等の近距離通信網３１によって情報集約通信部３２と接続されている。したがって、夫々のクレーン制御部３０の稼動情報は、近距離通信網３１を介して情報集約通信部３２で収集される。この情報集約通信部３２は、例えば工場の通信を妨害されない位置（家屋の天井付近）に配置される。 In FIG. 5, a crane control unit 30 consisting of the hoisting/traversing inverter control device 11 and the traveling inverter control device 13 shown in FIG. It is connected to the communication section 32. Therefore, the operation information of each crane control section 30 is collected by the information aggregation communication section 32 via the short-range communication network 31. The information aggregation communication unit 32 is placed, for example, in a position where communication in a factory is not interfered with (near the ceiling of a house).
　また、情報集約通信部３２は、先に説明した通り遠距離通信網２８を介してクラウドサーバ２４と接続されている。更に、夫々のクレーン制御部３０は、これも先に説明した通り近距離通信網２９を介して情報表示端末２６に接続されている。 Additionally, the information aggregation communication unit 32 is connected to the cloud server 24 via the long distance communication network 28, as described above. Furthermore, each crane control section 30 is connected to the information display terminal 26 via the short-range communication network 29, as described above.
　情報集約通信部３２は、夫々のクレーン制御部３０の個別の識別情報を付加してクレーン装置の稼動情報をクラウドサーバ２４に送信する。稼動情報は先に説明した通り、クレーン装置の稼働時間、クレーン装置の稼動回数、クレーン装置のエラー情報等のような比較的長い時間間隔でサンプリングされる動作情報であり、これらは所定時間毎に定期的にクラウドサーバ２４に送信される。そして、クラウドサーバ２４では、識別情報を参考にして夫々のクレーン装置毎に稼動情報を蓄積、記憶し、更に編集を行うことができる。 The information aggregation communication unit 32 adds individual identification information of each crane control unit 30 and transmits the operation information of the crane device to the cloud server 24. As explained above, operation information is operation information that is sampled at relatively long time intervals, such as the operating time of the crane device, the number of times the crane device is operated, and error information of the crane device, and these are sampled at predetermined intervals. It is sent to the cloud server 24 periodically. Then, in the cloud server 24, the operation information can be accumulated and stored for each crane device with reference to the identification information, and further edited.
　また、情報表示端末２６は、近距離通信網２９を介して夫々のクレーン制御部３０と接続されている。そして、情報表示端末２６の側でクレーン制御部３０を指定することで、指定されたクレーン制御部３０と近距離通信網２９を介して通信を実行することができる。この場合は、先に述べた通り保守、管理を行う上で、保守管理作業者がオンラインで把握したい運転時の電動機の電流値等の動作瞬時値が情報表示端末２６に送信される。 Furthermore, the information display terminal 26 is connected to each crane control section 30 via a short-range communication network 29. By specifying the crane control section 30 on the information display terminal 26 side, communication can be executed with the specified crane control section 30 via the short-range communication network 29. In this case, as described above, when performing maintenance and management, instantaneous operating values such as the current value of the motor during operation that the maintenance worker wants to know online are transmitted to the information display terminal 26.
　上述の図５に示す実施形態では、保守管理作業者がオンラインで把握したい運転時の電動機の電流値等の動作瞬時値が情報表示端末２６に送信されるが、情報集約通信部３２に送ることも可能である。 In the embodiment shown in FIG. 5 described above, the instantaneous operating values, such as the current value of the motor during operation, which the maintenance worker wants to understand online, are sent to the information display terminal 26; is also possible.
　図６において、クレーン装置の稼動情報に加えて、保守管理作業者がオンラインで把握したい運転時の電動機の電流値等の動作瞬時値も情報集約通信部３２に送信されている。この状態で情報表示端末２６から動作瞬時値の送信要求があると、情報集約通信部３２は、求められたクレーン装置の動作瞬時値を情報表示端末２６に送信する。この実施例でも、近距離通信網３１、２９を利用しているので通信費用は発生せず、また情報の即時性も損なうことがないものである。 In FIG. 6, in addition to the operation information of the crane device, instantaneous operating values such as the current value of the electric motor during operation that the maintenance worker wants to understand online are also transmitted to the information aggregation communication unit 32. In this state, when the information display terminal 26 issues a request to transmit the instantaneous operation value, the information aggregation communication unit 32 transmits the obtained instantaneous operation value of the crane device to the information display terminal 26. In this embodiment as well, since the short- range communication networks 31 and 29 are used, no communication costs are incurred, and the immediacy of information is not compromised.
　次に、クレーン装置における無線通信部２２の電源供給方式について説明する。インバータ式クレーン装置は、運転操作を実施しないときは入力装置のオフボタンを操作することで、インバータ式クレーン装置の電源供給部に設置されている主電源開閉器を操作して、インバータ式クレーン装置への電源供給を遮断するのが一般的である。 Next, a power supply system for the wireless communication section 22 in the crane device will be explained. When the inverter type crane equipment is not in operation, by operating the off button on the input device, the main power switch installed in the power supply section of the inverter type crane equipment is operated. It is common to cut off the power supply to the
　ただ、この場合は無線通信部２２の電源も遮断されるので、クラウドサーバ２４との遠距離通信網２８の実行タイミングによっては、最新の稼動情報をクラウドサーバ２４に送信できないという現象が発生する。 However, in this case, the power to the wireless communication unit 22 is also cut off, so depending on the timing of execution of the long-distance communication network 28 with the cloud server 24, a phenomenon occurs in which the latest operating information cannot be sent to the cloud server 24.
　本実施形態では、この現象を解消するために図７に示す構成を採用している。図７に示すように、クレーン制御部３０は主電源開閉器３３を介して３相電源に接続されている。したがって、３相電源３４からの電力は、クレーン制御部３０に供給される。主電源開閉器３３は、電磁リレー３５によって制御され、電磁リレー３５は、入力装置（起動ボタン）３５の操作によって動作される。 In this embodiment, the configuration shown in FIG. 7 is adopted to eliminate this phenomenon. As shown in FIG. 7, the crane control unit 30 is connected to a three-phase power source via a main power switch 33. Therefore, power from the three-phase power supply 34 is supplied to the crane control unit 30. The main power switch 33 is controlled by an electromagnetic relay 35, and the electromagnetic relay 35 is operated by operating the input device (start button) 35.
　したがって、入力装置３５をオフすると、電磁リレー３５によって主電源開閉器がオフされ、クレーン制御部３０の電力供給が遮断される。一方、無線通信部２２は、３相電源３４と無線通信部２２を繋ぐ電力供給線３７によって電力が直接的に供給されるので、通信が可能な状態に維持される。これによって、クレーン装置の最新の稼動情報をクラウドサーバ２４に送信することが可能となる。 Therefore, when the input device 35 is turned off, the main power switch is turned off by the electromagnetic relay 35, and the power supply to the crane control unit 30 is cut off. On the other hand, the wireless communication unit 22 is directly supplied with power by the power supply line 37 that connects the three-phase power source 34 and the wireless communication unit 22, so that the wireless communication unit 22 is maintained in a communicable state. This makes it possible to transmit the latest operating information of the crane device to the cloud server 24.
　尚、上述の電力供給線３７とは別に、入力装置３６の操作によっても電源が遮断されない構成、例えばバッテリー電源を設け、そこから直接的に無線通信部２２に電力を供給する構成にしても良い。 Incidentally, in addition to the power supply line 37 described above, a configuration in which the power is not cut off even when the input device 36 is operated, for example, a battery power source may be provided and power may be directly supplied to the wireless communication unit 22 from there. .
　以上述べた通り、クラウドサーバによってクレーン装置の最新の稼動情報をいつでも取得可能になり、クレーン装置の状態を常時監視することができるので、遠隔での状態監視を精度良く実施することができる。更に、同一の場所に設置された複数台のクレーン装置の夫々の状態を監視する場合、クラウドサーバと通信を実施する情報集約通信部を設け、クレーン装置と情報集約通信部を近距離通信網で接続して集約することで、総合的に通信費用を抑えることができる。 As mentioned above, the cloud server makes it possible to obtain the latest operating information of the crane equipment at any time, and the status of the crane equipment can be constantly monitored, so remote status monitoring can be carried out with high accuracy. Furthermore, when monitoring the status of multiple crane devices installed at the same location, an information aggregation communication unit that communicates with the cloud server is installed, and the crane devices and information aggregation communication unit are connected via a short-range communication network. By connecting and consolidating, you can reduce overall communication costs.
　尚、本発明は上記したいくつかの実施例に限定されるものではなく、様々な変形例が含まれる。上記の実施例は本発明を分かりやすく説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定されるものではない。また、ある実施例の構成の一部を他の実施例の構成に置き換えることが可能であり、ある実施例の構成に他の実施例の構成を加えることも可能である。各実施例の構成について、他の構成の追加、削除、置換をすることも可能である。 Note that the present invention is not limited to the few embodiments described above, and includes various modifications. The above-mentioned embodiments have been described in detail to explain the present invention in an easy-to-understand manner, and the present invention is not necessarily limited to having all the configurations described. Furthermore, it is possible to replace a part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment.
