FIG. 1 is a diagram showing the configuration of a control system according to a first embodiment of the present invention. The control system 101 includes a mobile elevator 60, which is an example of a control target device, one or more inverter devices that control driving of the mobile elevator 60, and a control device 10 that controls the operation of the inverter device. . In the control system 101, the inverter device and the control device 10 are connected by a network line 50 using an IP (Internet Protocol) network. The network line 50 may be wired or wireless. The inverter device provided in the control system 101 is an example of an electronic device. Here, the case where the control system 101 includes the traveling inverter device 30P and the raising and lowering inverter device 30Q will be described. In the following description, at least one of the traveling inverter device 30P and the raising and lowering inverter device 30Q may be referred to as an inverter device.
　移動式昇降機６０は、移動させる物体を載せて昇降する昇降テーブル６３と、昇降テーブル６３に接続されるとともにＸＹ平面内を移動する移動テーブル６４とを備えている。また、移動式昇降機６０は、昇降テーブル６３を昇降させるモータ６１Ｑと、移動テーブル６４を移動させるモータ６１Ｐとを備えている。モータ６１Ｐは、走行用インバータ装置３０Ｐに接続されており、走行用インバータ装置３０Ｐから送られてくる電圧に従って移動テーブル６４を移動させる。また、モータ６１Ｑは、昇降用インバータ装置３０Ｑに接続されており、昇降用インバータ装置３０Ｑから送られてくる電圧に従って昇降テーブル６３を移動させる。 The movable elevator 60 includes an elevation table 63 for placing and moving an object to be moved thereon, and a movement table 64 connected to the elevation table 63 and moving in the XY plane. The movable elevator 60 further includes a motor 61Q for moving the lifting table 63 up and down, and a motor 61P for moving the moving table 64. The motor 61P is connected to the traveling inverter device 30P, and moves the moving table 64 according to the voltage sent from the traveling inverter device 30P. The motor 61Q is connected to the lifting and lowering inverter device 30Q, and moves the lifting and lowering table 63 in accordance with the voltage sent from the lifting and lowering inverter device 30Q.
　走行用インバータ装置３０Ｐは、制御装置１０から受信する制御指令に基づいて、モータ６１Ｐに出力する電圧の周波数および大きさを制御する装置である。昇降用インバータ装置３０Ｑは、制御装置１０から受信する制御指令に基づいて、モータ６１Ｑに出力する電圧の周波数および大きさを制御する装置である。走行用インバータ装置３０Ｐは、直流電力を交流電力に変換する第１のインバータ回路を備えており、第１のインバータ回路を用いてモータ６１Ｐに出力する電圧の周波数および大きさを調整する。昇降用インバータ装置３０Ｑは、直流電力を交流電力に変換する第２のインバータ回路を備えており、第２のインバータ回路を用いてモータ６１Ｑに出力する電圧の周波数および大きさを調整する。実施の形態１では、走行用インバータ装置３０Ｐと昇降用インバータ装置３０Ｑとが、同一の型名、同一のインバータ容量および同一の製品バージョンであり、同一の機能を達成可能である場合について説明する。 The traveling inverter device 30P is a device that controls the frequency and the magnitude of the voltage output to the motor 61P based on the control command received from the control device 10. The lifting inverter device 30Q is a device that controls the frequency and magnitude of the voltage output to the motor 61Q based on the control command received from the control device 10.

The lifting inverter device 30Q includes a second inverter circuit that converts direct current power into alternating current power, and adjusts the frequency and magnitude of the voltage output to the motor 61Q using the second inverter circuit. In the first embodiment, the case where the traveling inverter device 30P and the lifting and lowering inverter device 30Q have the same model name, the same inverter capacity, and the same product version, and can achieve the same function will be described.
　制御装置１０は、走行用インバータ装置３０Ｐおよび昇降用インバータ装置３０Ｑを制御するコンピュータである。制御装置１０の例は、プログラマブルロジックコントローラ（ＰＬＣ：Programmable　Logic　Controller）である。 Control device 10 is a computer that controls traveling inverter device 30P and lifting inverter device 30Q. An example of the controller 10 is a programmable logic controller (PLC: Programmable Logic Controller).
　制御装置１０は、後述する対応関係情報７１を記憶する対応情報記憶部１１と、後述する制御プログラムを記憶するプログラム記憶部１３と、インバータ装置との間で通信を実行する通信部１４と、制御装置１０の全体を制御する制御部１２とを備えている。 The control device 10 includes a correspondence information storage unit 11 that stores correspondence relationship information 71, which will be described later, a program storage unit 13 that stores a control program, which will be described later, and a communication unit 14 that executes communication with the inverter device. A control unit 12 that controls the entire apparatus 10 is provided.
　第１の対応関係情報である対応関係情報７１は、ネットワーク回線５０に接続されたインバータ装置を識別するための識別情報と、インバータ装置のＩＰアドレスとの対応関係を示す情報である。 The correspondence relationship information 71, which is first correspondence relationship information, is information indicating the correspondence relationship between identification information for identifying the inverter device connected to the network line 50 and the IP address of the inverter device.
　実施の形態１では、走行用インバータ装置３０Ｐに「１２３４」の識別情報が割り付けられ、昇降用インバータ装置３０Ｑに「５６７８」の識別情報が割り付けられる場合について説明する。識別情報は、ネットワーク回線５０上でインバータ装置に割り付けられる通信アドレスとは異なる情報である。識別情報は、ネットワーク回線５０上でインバータ装置を識別するための情報であり、識別情報の設定者が任意に設定可能なインバータ装置に固有の情報である。識別情報の例は、識別パラメータである。識別情報は、制御システム１０１の使用者である設定者によってインバータ装置に設定される。 In the first embodiment, a case will be described where identification information of "1234" is allocated to the traveling inverter device 30P and identification information of "5678" is allocated to the lifting inverter device 30Q. The identification information is information different from the communication address assigned to the inverter device on the network line 50. The identification information is information for identifying the inverter device on the network line 50, and is information unique to the inverter device that can be arbitrarily set by a person who sets the identification information. An example of identification information is an identification parameter. The identification information is set in the inverter device by a setter who is a user of the control system 101.
　制御プログラムは、インバータ装置への制御指令を生成するためのプログラムであり、移動式昇降機６０を制御する際に実行される。制御プログラムは、識別情報を用いて作成されている。具体的には、制御プログラムでは、制御装置１０による被制御機器であるインバータ装置が識別情報によって指定されている。したがって、ネットワーク回線５０内でインバータ装置の追加または変更があってインバータ装置のＩＰアドレスが変更された場合であっても、制御装置１０は、識別情報に基づいた制御を実行できる。 The control program is a program for generating a control command to the inverter device, and is executed when controlling the mobile elevator 60. The control program is created using identification information. Specifically, in the control program, the inverter device, which is a controlled device by the control device 10, is designated by the identification information. Therefore, even when the inverter apparatus is added or changed in the network line 50 and the IP address of the inverter apparatus is changed, the control apparatus 10 can execute control based on the identification information.
　また、制御部１２は、対応情報記憶部１１、プログラム記憶部１３および通信部１４を制御する。制御部１２は、インバータ装置への識別情報の取得要求を通信部１４に送信させる。これにより、通信部１４は、識別情報の取得要求を、ネットワーク回線５０上にブロードキャストし、インバータ装置から識別情報を受信する。通信部１４は、受信した識別情報を制御部１２に送信する。 Further, the control unit 12 controls the correspondence information storage unit 11, the program storage unit 13 and the communication unit 14. The control unit 12 causes the communication unit 14 to transmit an acquisition request for identification information to the inverter device. Thereby, the communication unit 14 broadcasts an acquisition request for identification information on the network line 50, and receives the identification information from the inverter device. The communication unit 14 transmits the received identification information to the control unit 12.
　また、制御部１２は、インバータ装置から取得した識別情報に基づいて対応関係情報７１を作成し、作成した対応関係情報７１を対応情報記憶部１１に格納する。また、制御部１２は、移動式昇降機６０を制御する際には、制御プログラム内のプログラム指令を読み出す。そして、制御部１２は、プログラム指令に基づいて、インバータ装置を制御するための制御指令を生成する。 Further, the control unit 12 creates the correspondence relationship information 71 based on the identification information acquired from the inverter device, and stores the created correspondence relationship information 71 in the correspondence information storage unit 11. In addition, when controlling the mobile elevator 60, the control unit 12 reads a program command in the control program. Then, the control unit 12 generates a control command for controlling the inverter device based on the program command.
　また、制御部１２は、移動式昇降機６０を制御する際には、制御プログラム内で指定されている識別情報を読み出し、この識別情報に対応するＩＰアドレスを、対応関係情報７１から抽出する。インバータ装置への制御指令の例は、移動式昇降機６０を制御するための指令であり、出力周波数または出力電圧といった、移動式昇降機６０の駆動のさせ方、すなわち駆動条件を指示する制御指令である。制御部１２は、読み出した識別情報を、生成した制御指令に付加して通信部１４に送信させる。 Further, when controlling the movable elevator 60, the control unit 12 reads out the identification information designated in the control program, and extracts the IP address corresponding to the identification information from the correspondence information 71. An example of a control command to the inverter device is a command for controlling the mobile elevator 60, and is a control command for instructing how to drive the mobile elevator 60, that is, a drive condition, such as an output frequency or an output voltage. . The control unit 12 adds the read identification information to the generated control command and causes the communication unit 14 to transmit it.
　通信部１４は、制御部１２が抽出したＩＰアドレスを宛先に設定して、識別情報が付加された制御指令を送信する。通信部１４は、走行用インバータ装置３０Ｐおよび昇降用インバータ装置３０Ｑに接続されている。したがって、通信部１４が送信する制御指令は、走行用インバータ装置３０Ｐまたは昇降用インバータ装置３０Ｑが受信する。 The communication unit 14 sets the IP address extracted by the control unit 12 as the destination, and transmits the control command to which the identification information is added. The communication unit 14 is connected to the traveling inverter device 30P and the lifting inverter device 30Q. Therefore, the control command transmitted by the communication unit 14 is received by the traveling inverter device 30P or the lifting inverter device 30Q.
　なお、制御装置１０は、インバータ装置から見た外部装置の例であり、制御装置１０以外の装置が、制御装置１０と同様の機能を有していてもよい。例えば、クラウドコンピューティングを用いることによって、制御装置１０と同様の機能を有した外部装置が、インバータ装置を制御してもよい。また、制御装置１０と同様の機能を有した装置を、インバータ装置の何れかに配置してもよい。 Control device 10 is an example of an external device seen from an inverter device, and devices other than control device 10 may have the same function as control device 10. For example, by using cloud computing, an external device having the same function as the control device 10 may control the inverter device. Further, a device having the same function as the control device 10 may be disposed in any of the inverter devices.
　つぎに、実施の形態１にかかるインバータ装置の構成について説明する。図２は、実施の形態１にかかるインバータ装置の構成を示すブロック図である。図２に示すインバータ装置２０は、走行用インバータ装置３０Ｐまたは昇降用インバータ装置３０Ｑである。 Below, the structure of the inverter apparatus concerning Embodiment 1 is demonstrated. FIG. 2 is a block diagram showing the configuration of the inverter device according to the first embodiment. The inverter device 20 shown in FIG. 2 is a traveling inverter device 30P or a lifting inverter device 30Q.
　インバータ装置２０は、制御装置１０との間で通信を実行する通信部２１と、設定者がインバータ装置２０に入力する識別情報を受付ける受付部２２と、自機器または自装置の識別情報を記憶する識別情報記憶部２４とを備えている。また、インバータ装置２０は、移動式昇降機６０に電圧を出力する出力部２５と、インバータ装置２０の全体を制御する制御部２３とを備えている。 The inverter device 20 stores the communication unit 21 that executes communication with the control device 10, the reception unit 22 that receives identification information input to the inverter device 20 by the setter, and identification information of the own device or the own device. An identification information storage unit 24 is provided. In addition, the inverter device 20 includes an output unit 25 that outputs a voltage to the movable elevator 60, and a control unit 23 that controls the entire inverter device 20.
　受付部２２は、設定者からの識別情報を受付けると、受付けた識別情報を制御部２３に送信する。設定者によるインバータ装置２０への識別情報の入力は、インバータ装置２０の出荷前であってもよいし、インバータ装置２０の出荷後であってもよい。インバータ装置２０の出荷前に識別情報が入力される場合、インバータ装置２０の製造者が識別情報を受付部２２に入力する。また、インバータ装置２０の出荷後に識別情報が入力される場合、インバータ装置２０の使用者が識別情報を受付部２２に入力する。 When receiving the identification information from the setter, the receiving unit 22 transmits the received identification information to the control unit 23. The input of the identification information to the inverter device 20 by the setter may be before shipment of the inverter device 20 or may be after shipment of the inverter device 20. When the identification information is input before the shipment of the inverter device 20, the manufacturer of the inverter device 20 inputs the identification information to the reception unit 22. When the identification information is input after the shipment of the inverter device 20, the user of the inverter device 20 inputs the identification information to the reception unit 22.
　通信部２１は、インバータ装置２０への識別情報の取得要求を受信して制御部２３に送信する。また、通信部２１は、制御部２３からの指示に従って、インバータ装置２０の識別情報を制御装置１０に送信する。また、通信部２１は、制御装置１０から制御指令を受信して制御部２３に送信する。 The communication unit 21 receives an acquisition request for identification information to the inverter device 20 and transmits the request to the control unit 23. Further, the communication unit 21 transmits identification information of the inverter device 20 to the control device 10 in accordance with an instruction from the control unit 23. The communication unit 21 also receives a control command from the control device 10 and transmits the control command to the control unit 23.
　制御部２３は、通信部２１、受付部２２、識別情報記憶部２４および出力部２５を制御する。制御部２３は、受付部２２から識別情報を受信すると、受信した識別情報を識別情報記憶部２４に格納する。また、制御部２３は、識別情報の取得要求を受信すると、識別情報記憶部２４から識別情報を読み出し、制御装置１０を宛先として通信部２１に識別情報を送信させる。また、制御部２３は、制御装置１０からの制御指令を受信すると、受信した制御指令に付加されている識別情報を読み出し、識別情報記憶部２４内の識別情報と比較する。制御部２３は、制御指令から読み出した識別情報が識別情報記憶部２４内の識別情報に一致する場合、受信した制御指令に対応する電圧を生成する。 The control unit 23 controls the communication unit 21, the reception unit 22, the identification information storage unit 24, and the output unit 25. When receiving the identification information from the reception unit 22, the control unit 23 stores the received identification information in the identification information storage unit 24. Further, when receiving the acquisition request for identification information, the control unit 23 reads out the identification information from the identification information storage unit 24 and causes the communication unit 21 to transmit the identification information to the control device 10 as a destination. Further, when receiving the control command from the control device 10, the control unit 23 reads out the identification information added to the received control command, and compares it with the identification information in the identification information storage unit 24. When the identification information read from the control command matches the identification information in the identification information storage unit 24, the control unit 23 generates a voltage corresponding to the received control command.
　インバータ装置２０が走行用インバータ装置３０Ｐである場合、制御部２３は、モータ６１Ｐへ出力する電圧を生成するための制御指令を制御装置１０から受信する。したがって、インバータ装置２０が走行用インバータ装置３０Ｐである場合、制御部２３は、制御装置１０からの制御指令に基づいて、モータ６１Ｐに出力するための電圧を生成する。 When inverter device 20 is traveling inverter device 30P, control unit 23 receives from control device 10 a control command for generating a voltage to be output to motor 61P. Therefore, when inverter device 20 is traveling inverter device 30P, control unit 23 generates a voltage to be output to motor 61P based on a control command from control device 10.
　インバータ装置２０が昇降用インバータ装置３０Ｑである場合、制御部２３は、モータ６１Ｑへ出力する電圧を生成するための制御指令を制御装置１０から受信する。したがって、インバータ装置２０が昇降用インバータ装置３０Ｑである場合、制御部２３は、制御装置１０からの制御指令に基づいて、モータ６１Ｑに出力するための電圧を生成する。 When inverter device 20 is elevating inverter device 30Q, control unit 23 receives from control device 10 a control command for generating a voltage to be output to motor 61Q. Therefore, when inverter device 20 is elevating inverter device 30Q, control unit 23 generates a voltage to be output to motor 61Q based on a control command from control device 10.
　インバータ装置２０が走行用インバータ装置３０Ｐである場合、出力部２５は、制御部２３が生成した電圧をモータ６１Ｐに出力する。インバータ装置２０が昇降用インバータ装置３０Ｑである場合、出力部２５は、制御部２３が生成した電圧をモータ６１Ｑに出力する。 When the inverter device 20 is the traveling inverter device 30P, the output unit 25 outputs the voltage generated by the control unit 23 to the motor 61P. When the inverter device 20 is the lifting inverter device 30Q, the output unit 25 outputs the voltage generated by the control unit 23 to the motor 61Q.
　制御システム１０１では、インバータ装置２０の通信部２１が第１の通信部であり、制御装置１０の通信部１４が第２の通信部である。また、制御システム１０１では、インバータ装置２０の制御部２３が第１の制御部であり、制御装置１０の制御部１２が第２の制御部である。 In the control system 101, the communication unit 21 of the inverter device 20 is a first communication unit, and the communication unit 14 of the control device 10 is a second communication unit. Further, in the control system 101, the control unit 23 of the inverter device 20 is a first control unit, and the control unit 12 of the control device 10 is a second control unit.
　ここで、制御装置１０が記憶する対応関係情報７１の構成について説明する。図３は、実施の形態１にかかる対応関係情報の構成を示す図である。対応関係情報７１は、インバータ装置２０を個別に識別するための識別情報と、インバータ装置２０のＩＰアドレスとの対応関係がインバータ装置２０毎に設定された情報である。 Here, the configuration of the correspondence relationship information 71 stored in the control device 10 will be described. FIG. 3 is a diagram showing the configuration of correspondence relationship information according to the first embodiment. The correspondence relationship information 71 is information in which the correspondence relationship between identification information for individually identifying the inverter devices 20 and the IP address of the inverter devices 20 is set for each of the inverter devices 20.
　ＩＰアドレスは、インバータ装置２０が接続されたネットワーク回線５０内でインバータ装置２０に割り付けられる通信アドレスの例である。したがって、対応関係情報７１は、識別情報と、ＩＰアドレス以外の通信アドレスとの対応関係であってもよい。ネットワーク回線５０内では、後述するＤＨＣＰ（ダイナミック　ホスト　コンフィギュレーション　プロトコル：Dynamic　Host　Configuration　Protocol）によって、インバータ装置２０毎に異なるＩＰアドレスが割り付けられる。なお、ＩＰアドレスは、ＤＨＣＰを使用せず、手動で設定されてもよい。 The IP address is an example of a communication address assigned to the inverter device 20 in the network line 50 to which the inverter device 20 is connected. Therefore, the correspondence relationship information 71 may be a correspondence relationship between the identification information and a communication address other than the IP address. In the network line 50, a different IP address is assigned to each inverter device 20 by Dynamic Host Configuration Protocol (DHCP) described later. The IP address may be set manually without using DHCP.
　つぎに、対応関係情報７１の作成処理手順について説明する。図４は、実施の形態１にかかる対応関係情報の作成処理手順を示すフローチャートである。ここでは、制御システム１０１による対応関係情報７１の作成処理手順について説明する。ステップＳ１０において、制御装置１０は、インバータ装置２０の識別情報を用いて作成された制御プログラムをプログラム記憶部１３内に格納する。インバータ装置２０の識別情報の例は、走行用インバータ装置３０Ｐの識別情報である「１２３４」または昇降用インバータ装置３０Ｑの識別情報である「５６７８」である。なお、ステップＳ１０の処理は、何れのタイミングで実行されてもよい。すなわち、実施の形態１では、識別情報を用いて制御プログラムが作成されるので、制御プログラムは、何れのタイミングで作成されてもよい。制御プログラムは、後述するステップＳ２０からＳ５０の処理の影響を受けないからである。 Below, the preparation process procedure of the correspondence information 71 is demonstrated. FIG. 4 is a flowchart of a process of creating correspondence information according to the first embodiment. Here, the processing procedure of creating the correspondence relationship information 71 by the control system 101 will be described. In step S <b> 10, the control device 10 stores a control program created using identification information of the inverter device 20 in the program storage unit 13. An example of the identification information of the inverter device 20 is “1234” which is identification information of the traveling inverter device 30P or “5678” which is identification information of the lifting inverter device 30Q. The process of step S10 may be performed at any timing. That is, in the first embodiment, since the control program is created using the identification information, the control program may be created at any timing. This is because the control program is not influenced by the processes of steps S20 to S50 described later.
　ステップＳ２０において、インバータ装置２０が、自装置の識別情報を格納する。具体的には、設定者がインバータ装置２０に識別情報を入力すると、受付部２２が識別情報を受付けて制御部２３に送信する。そして、制御部２３が、識別情報を識別情報記憶部２４に格納する。走行用インバータ装置３０Ｐへは、走行用インバータ装置３０Ｐの識別情報である「１２３４」が入力されるので、走行用インバータ装置３０Ｐの識別情報記憶部２４は、「１２３４」を記憶する。また、昇降用インバータ装置３０Ｑへは、昇降用インバータ装置３０Ｑの識別情報である「５６７８」が入力されるので、昇降用インバータ装置３０Ｑの識別情報記憶部２４は、「５６７８」を記憶する。 In step S20, the inverter device 20 stores its own identification information. Specifically, when the setter inputs the identification information to the inverter device 20, the receiving unit 22 receives the identification information and transmits it to the control unit 23. Then, the control unit 23 stores the identification information in the identification information storage unit 24. Since “1234”, which is identification information of the traveling inverter device 30P, is input to the traveling inverter device 30P, the identification information storage unit 24 of the traveling inverter device 30P stores “1234”. Further, since “5678”, which is identification information of the lifting inverter device 30Q, is input to the lifting inverter device 30Q, the identification information storage unit 24 of the lifting inverter device 30Q stores “5678”.
　この後、ステップＳ３０において、制御装置１０の制御部１２は、インバータ装置２０に識別情報を問い合わせる。具体的には、制御部１２が、インバータ装置２０への識別情報の取得要求を通信部１４に送信させる。これにより、通信部１４は、識別情報の取得要求を、ネットワーク回線５０上にブロードキャストする。そして、インバータ装置２０が識別情報の取得要求を受信する。 Thereafter, in step S30, the control unit 12 of the control device 10 queries the inverter device 20 for identification information. Specifically, the control unit 12 causes the communication unit 14 to transmit a request for acquiring identification information to the inverter device 20. Thereby, the communication unit 14 broadcasts an acquisition request for identification information on the network line 50. Then, the inverter device 20 receives the acquisition request for identification information.
　ステップＳ４０において、ネットワーク回線５０上のインバータ装置２０は、制御装置１０に識別情報を送信する。具体的には、インバータ装置２０の制御部２３が、識別情報記憶部２４から識別情報を読み出す。そして、通信部２１が、識別情報を制御装置１０に送信する。走行用インバータ装置３０Ｐは、走行用インバータ装置３０Ｐの識別情報である「１２３４」を制御装置１０に送信し、昇降用インバータ装置３０Ｑは、昇降用インバータ装置３０Ｑの識別情報である「５６７８」を制御装置１０に送信する。 In step S <b> 40, the inverter device 20 on the network line 50 transmits the identification information to the control device 10. Specifically, the control unit 23 of the inverter device 20 reads the identification information from the identification information storage unit 24. Then, the communication unit 21 transmits the identification information to the control device 10. The traveling inverter device 30P transmits "1234", which is identification information of the traveling inverter device 30P, to the control device 10. The raising and lowering inverter device 30Q controls "5678" which is identification information of the raising and lowering inverter device 30Q. Send to device 10
　これにより、制御装置１０は、インバータ装置２０からの識別情報を受信する。そして、ステップＳ５０において、制御装置１０が、対応関係情報７１を作成する。具体的には、制御装置１０の制御部１２が、インバータ装置２０からの識別情報と、ＤＨＣＰあるいは手動によって割り付けられたインバータ装置２０のＩＰアドレスとに基づいて、対応関係情報７１を作成する。ＤＨＣＰは、インバータ装置２０といったコンピュータがネットワーク回線５０に接続する際に必要な情報を自動的に割り当てるプロトコルである。制御部１２は、作成した対応関係情報７１を対応情報記憶部１１に格納する。 Thereby, the control device 10 receives the identification information from the inverter device 20. Then, in step S50, the control device 10 creates the correspondence relationship information 71. Specifically, the control unit 12 of the control device 10 creates the correspondence information 71 based on the identification information from the inverter device 20 and the IP address of the inverter device 20 allocated by DHCP or manually. DHCP is a protocol that automatically assigns information required when a computer such as the inverter device 20 connects to the network line 50. The control unit 12 stores the created correspondence relationship information 71 in the correspondence information storage unit 11.
　つぎに、制御システム１０１による制御処理手順について説明する。図５は、実施の形態１にかかる制御システムの制御処理手順を示すフローチャートである。移動式昇降機６０を動作させる際には、ステップＳ１１０において、制御装置１０がプログラム記憶部１３から制御プログラムを読み出す。 Below, the control processing procedure by the control system 101 is demonstrated. FIG. 5 is a flowchart of a control processing procedure of the control system according to the first embodiment. When operating the movable elevator 60, the controller 10 reads the control program from the program storage unit 13 in step S110.
　そして、制御装置１０の制御部１２が、制御プログラムを実行する。このとき、制御部１２は、制御プログラム内からプログラム指令と、このプログラム指令に対応付けされたインバータ装置２０の識別情報とを読み出す。制御プログラムから読み出したプログラム指令が、走行用インバータ装置３０Ｐへの指令である場合、制御部１２は、プログラム指令に基づいて、走行用インバータ装置３０Ｐへの制御指令を生成する。 Then, the control unit 12 of the control device 10 executes the control program. At this time, the control unit 12 reads a program command and identification information of the inverter device 20 associated with the program command from within the control program. When the program command read from the control program is a command to the traveling inverter device 30P, the control unit 12 generates a control command to the traveling inverter device 30P based on the program command.
　制御部１２が制御プログラムに従って、制御指令をインバータ装置２０に送信する際には、制御部１２は、対応情報記憶部１１内の対応関係情報７１を読み出す。そして、ステップＳ１２０において、制御部１２は、読み出した識別情報に対応するＩＰアドレスを、対応関係情報７１から抽出する。読み出した識別情報が走行用インバータ装置３０Ｐの識別情報である場合、制御部１２は、走行用インバータ装置３０ＰのＩＰアドレスを対応関係情報７１から抽出する。 When control unit 12 transmits a control command to inverter device 20 according to the control program, control unit 12 reads correspondence relationship information 71 in correspondence information storage unit 11. Then, in step S120, the control unit 12 extracts an IP address corresponding to the read identification information from the correspondence relationship information 71. When the read identification information is identification information of the traveling inverter device 30P, the control unit 12 extracts the IP address of the traveling inverter device 30P from the correspondence information 71.
　そして、制御部１２は、識別情報を付加した制御指令を生成する。この制御指令の宛先は、識別情報に対応するＩＰアドレスである。この後、ステップＳ１３０において、制御装置１０は、識別情報が付加された制御指令を、インバータ装置２０のＩＰアドレスに送信する。例えば、制御プログラムのプログラム指令が、走行用インバータ装置３０Ｐへのプログラム指令である場合、制御装置１０は、走行用インバータ装置３０Ｐの識別情報を付加した制御指令を、走行用インバータ装置３０ＰのＩＰアドレスに送信する。 Then, the control unit 12 generates a control command to which identification information is added. The destination of this control command is an IP address corresponding to the identification information. Thereafter, in step S130, the control device 10 transmits the control command to which the identification information is added to the IP address of the inverter device 20. For example, when the program command of the control program is a program command to the traveling inverter device 30P, the control device 10 adds the identification information of the traveling inverter device 30P to the IP address of the traveling inverter device 30P. Send to
　これにより、インバータ装置２０が、制御装置１０からの制御指令を受信する。そして、ステップＳ１４０において、インバータ装置２０の制御部２３が、受信した制御指令に付加されている識別情報に基づいて、自装置宛ての指令であるか否かを判定する。具体的には、制御部２３が、識別情報記憶部２４内の識別情報と、受信した制御指令に付加されている識別情報とが一致するか否かを判定する。換言すると、制御部２３が、自装置の識別情報と、制御装置１０からの識別情報とが一致するか否かを判定する。 Thus, the inverter device 20 receives the control command from the control device 10. Then, in step S140, the control unit 23 of the inverter device 20 determines, based on the identification information added to the received control command, whether or not the command is for the own device. Specifically, the control unit 23 determines whether or not the identification information in the identification information storage unit 24 matches the identification information added to the received control command. In other words, the control unit 23 determines whether the identification information of the own device and the identification information from the control device 10 match.
　受信した制御指令が自装置宛てである場合、すなわちステップＳ１５０において、Ｙｅｓの場合、ステップＳ１６０において、制御部２３は、受信した制御指令に基づいて移動式昇降機６０のモータ６１Ｐ，６１Ｑを駆動する。制御指令を受信したインバータ装置２０が走行用インバータ装置３０Ｐである場合、走行用インバータ装置３０Ｐは、受信した制御指令を用いてモータ６１Ｐを駆動させる。制御指令を受信したインバータ装置２０が昇降用インバータ装置３０Ｑである場合、昇降用インバータ装置３０Ｑは、受信した制御指令を用いてモータ６１Ｑを駆動させる。 When the received control command is addressed to the own apparatus, that is, in the case of Yes in step S150, the control unit 23 drives the motors 61P and 61Q of the movable elevator 60 based on the received control command in step S160. When the inverter device 20 that has received the control command is the traveling inverter device 30P, the traveling inverter device 30P drives the motor 61P using the received control command. When the inverter device 20 that receives the control command is the lifting inverter device 30Q, the lifting inverter device 30Q drives the motor 61Q using the received control command.
　受信した制御指令が自装置宛てではない場合、すなわちステップＳ１５０において、Ｎｏの場合、ステップＳ１７０において、制御部２３は、受信した制御指令を破棄する。このように、制御部２３は、受信した制御指令が、自装置の識別情報が付加された第１の制御指令であれば、第１の制御指令を用いてモータ６１Ｐ，６１Ｑを駆動する。また、制御部２３は、受信した制御指令が、自装置の識別情報が付加されていない第２の制御指令であれば、受信した第２の制御指令を破棄する。 When the received control command is not addressed to the own apparatus, that is, in the case of No in step S150, the control unit 23 discards the received control command in step S170. As described above, when the received control command is the first control command to which the identification information of the own device is added, the control unit 23 drives the motors 61P and 61Q using the first control command. If the received control command is a second control command to which the identification information of the own device is not added, the control unit 23 discards the received second control command.
　このように、制御システム１０１は、通信処理の際には、ＩＰアドレスまたは局番といったネットワーク通信に必要な通信アドレスを用いて、個々のインバータ装置２０を識別している。そして、制御システム１０１は、インバータ装置２０を制御する際には、通信アドレスを用いることなく、識別情報によってインバータ装置２０を識別する。換言すると、制御システム１０１は、通信処理の際には通信アドレスによってインバータ装置２０を識別し、制御処理の際には識別情報によってインバータ装置２０を識別する。 Thus, the control system 101 identifies each inverter device 20 using a communication address necessary for network communication such as an IP address or a station number at the time of communication processing. Then, when controlling the inverter device 20, the control system 101 identifies the inverter device 20 by the identification information without using the communication address. In other words, the control system 101 identifies the inverter device 20 by the communication address in the communication process, and identifies the inverter device 20 by the identification information in the control process.
　ここで、ＩＰアドレスが設定されたインバータ装置の移設処理について説明する。図６は、実施の形態１にかかる、インバータ装置に設定される識別情報およびＩＰアドレスを説明するための図であり、図７は、識別情報およびＩＰアドレスが設定されたインバータ装置の実施の形態１にかかる移設処理を説明するための図である。 Here, transfer processing of the inverter apparatus in which the IP address is set will be described. FIG. 6 is a diagram for explaining identification information and an IP address set in the inverter device according to the first embodiment, and FIG. 7 is an embodiment of the inverter device in which identification information and an IP address are set. It is a figure for demonstrating the transfer processing concerning 1. FIG.
　図６に示す制御システム１０２は、制御装置１０が、イーサネット（登録商標）を用いたネットワーク回線５１に接続された５台のインバータ装置２０Ａ～２０Ｅを制御するシステムである。図７に示す制御システム１０３は、図６に示したインバータ装置２０Ａ～２０Ｅをネットワーク回線５１とは異なる他のネットワーク回線５２に移設した場合のシステムである。なお、図６および図７では、移動式昇降機６０といったインバータ装置２０による制御対象の図示を省略している。インバータ装置２０Ａ～２０Ｅは、走行用インバータ装置３０Ｐまたは昇降用インバータ装置３０Ｑといったインバータ装置２０の一例である。 The control system 102 shown in FIG. 6 is a system in which the control device 10 controls five inverter devices 20A to 20E connected to a network line 51 using Ethernet (registered trademark). The control system 103 shown in FIG. 7 is a system in which the inverter devices 20A to 20E shown in FIG. 6 are transferred to another network line 52 different from the network line 51. 6 and 7, illustration of a control target by the inverter device 20 such as the movable elevator 60 is omitted. The inverter devices 20A to 20E are an example of the inverter device 20 such as the traveling inverter device 30P or the lifting inverter device 30Q.
　図６に示すように、インバータ装置２０Ａ～２０Ｅは、ネットワーク回線５１を介して接続されている。ここでは、インバータ装置２０Ａ～２０Ｅに、識別情報として、「１１００」～「１１０４」が設定されている場合について説明する。 As shown in FIG. 6, the inverter devices 20A to 20E are connected via the network line 51. Here, the case where “1100” to “1104” are set as identification information in the inverter devices 20A to 20E will be described.
　制御装置１０は、インバータ装置２０Ａ～２０Ｅをネットワーク回線５１に接続するために、ＩＰアドレス、サブネットマスクデータまたはゲートウェイアドレスといった通信アドレスを５台のインバータ装置２０Ａ～２０Ｅに設定しておく必要がある。 In order to connect the inverter devices 20A to 20E to the network line 51, the control device 10 needs to set communication addresses such as an IP address, subnet mask data or a gateway address in the five inverter devices 20A to 20E.
　ここで、図６に示すように、制御装置１０が、ＩＰアドレスとして192.168.0.1～192.168.0.5をインバータ装置２０Ａ～２０Ｅに割り付けた後、これらのインバータ装置２０Ａ～２０Ｅを含んだ制御システム１０２をネットワーク回線５１とは異なる図７のネットワーク回線５２に移設することを想定する。ネットワーク回線５１，５２の例は、イーサネットを用いたネットワークである。このような条件において、移設先のネットワーク回線５２において、既に192.168.0.3を使用している機器３５が存在する場合がある。この場合、制御装置１０は、インバータ装置２０Ａ～２０Ｅのうち192.168.0.3が割り当てられているインバータ装置２０ＣのＩＰアドレスを、移設先の機器３５と重複しない192.168.0.6といった別のＩＰアドレスに変更する必要がある。 Here, as shown in FIG. 6, after the control device 10 allocates 192.168.0.1 to 192.168.0.5 as the IP address to the inverter devices 20A to 20E, the control system 102 including the inverter devices 20A to 20E is obtained. It is assumed that the network line 52 of FIG. 7 different from the network line 51 is relocated. An example of the network lines 51 and 52 is a network using Ethernet. Under such conditions, there may be a device 35 already using 192.168.0.3 in the network line 52 of the transfer destination. In this case, the control device 10 changes the IP address of the inverter device 20C to which 192.168.0.3 is assigned among the inverter devices 20A to 20E to another IP address such as 192.168.0.6 which does not overlap with the device 35 of the transfer destination. There is a need.
　実施の形態１の制御装置１０は、識別情報を用いて、インバータ装置２０Ａ～２０Ｅを識別したうえで、インバータ装置２０Ａ～２０Ｅへの制御を実行する。このため、ＩＰアドレスの変更は、インバータ装置２０Ａ～２０Ｅへの制御に影響しない。すなわち、制御装置１０は、インバータ装置２０Ａ～２０Ｅに対する制御を、識別情報に基づいて実行するので、制御対象として選択されるインバータ装置２０のＩＰアドレスは、制御とは無関係となる。 The control device 10 according to the first embodiment identifies the inverter devices 20A to 20E using the identification information, and then executes control on the inverter devices 20A to 20E. Therefore, the change of the IP address does not affect the control of the inverter devices 20A to 20E. That is, since the control device 10 executes control on the inverter devices 20A to 20E based on the identification information, the IP address of the inverter device 20 selected as the control target is irrelevant to the control.
　したがって、ここでの制御装置１０は、インバータ装置２０Ｃに対しては、識別情報である「１１０２」に対して制御を行うことになる。このように、インバータ装置２０ＣのＩＰアドレスが192.168.0.6に変更された場合であっても、制御装置１０は、対応関係情報７１を更新すればよく、インバータ装置２０Ａ～２０Ｅへの制御の設定である制御設定を変更する必要は無い。 Therefore, the control device 10 here controls the inverter device 20C with respect to the identification information “1102”. As described above, even when the IP address of the inverter device 20C is changed to 192.168.0.6, the control device 10 may update the correspondence relationship information 71, by setting control to the inverter devices 20A to 20E. There is no need to change certain control settings.
　また、制御装置１０は、ＩＰアドレスを自由に設定できるので、ＤＨＣＰ機能で自動的にＩＰアドレスを割り付けることが可能となる。また、インバータ装置２０Ａ～２０Ｅを移設する際にも、制御装置１０は、自由にＩＰアドレスを設定することができる。 Further, since the control device 10 can freely set the IP address, it becomes possible to automatically assign the IP address by the DHCP function. Also, when transferring the inverter devices 20A to 20E, the control device 10 can freely set an IP address.
　ここで、比較例の制御装置および比較例のインバータ装置について説明する。比較例の制御装置および比較例のインバータ装置は、識別情報を用いずに動作する。すなわち、比較例の制御装置は、ＩＰアドレスのみで比較例のインバータ装置を制御する。 Here, the control device of the comparative example and the inverter device of the comparative example will be described. The control device of the comparative example and the inverter device of the comparative example operate without using identification information. That is, the control device of the comparative example controls the inverter device of the comparative example only with the IP address.
　比較例の制御装置は、比較例のインバータ装置を移設する際に、移設先のネットワーク回線５２において192.168.0.6といったＩＰアドレスが空いていれば、移動させる比較例のインバータ装置のＩＰアドレスを、元のＩＰアドレスである192.168.0.3から空いている192.168.0.6に変更することが考えられる。この場合、比較例の制御装置は、192.168.0.3向けに行っていた制御を192.168.0.6向けの制御に修正する必要が生じる。このような制御の修正が発生すると、制御プログラムを変更しなければならない場合がある。また、比較例の制御装置がＤＨＣＰ機能を用いる場合、比較例の制御装置は、比較例のインバータ装置に割り付けられたＩＰアドレスに基づいて、制御設定を修正する必要が生じる。このように、比較例の制御装置および比較例のインバータ装置が用いられる場合、ＩＰアドレスの変更を伴うシステムの変更があると、制御の変更に多くの手間がかかる。 When transferring the inverter device of the comparative example, if the IP address such as 192.168.0.6 on the transfer destination network line 52 is vacant when transferring the inverter device of the comparative example, the IP address of the inverter device of the comparative example to be moved is It is possible to change from the IP address of 192.168.0.3 to the free 192.168.0.6. In this case, the control device of the comparative example needs to correct the control performed for 192.168.0.3 to control for 192.168.0.6. When such control modifications occur, it may be necessary to change the control program. In addition, when the control device of the comparative example uses the DHCP function, the control device of the comparative example needs to correct the control setting based on the IP address assigned to the inverter device of the comparative example. As described above, in the case where the control device of the comparative example and the inverter device of the comparative example are used, if there is a change of the system accompanied by a change of the IP address, it takes much time and effort to change the control.
　一方、実施の形態１の制御装置１０は、ＩＰアドレスの変更を伴う制御システム１０１の変更があった場合、対応関係情報７１を更新すればよいので、容易にインバータ装置２０の制御設定を行うことができる。 On the other hand, when there is a change in the control system 101 accompanied by a change in the IP address, the control device 10 according to the first embodiment only needs to update the correspondence relationship information 71. Therefore, the control setting of the inverter device 20 is easily performed. Can.
　このように、実施の形態１によれば、インバータ装置２０が、識別情報に基づいて自装置宛ての制御指令であるか否かを判定するので、インバータ装置２０は容易に制御装置１０からの制御指令を取得することができる。 As described above, according to the first embodiment, since the inverter device 20 determines whether or not the control command is directed to the own device based on the identification information, the inverter device 20 can easily perform control from the control device 10. You can get the command.
　また、設定者が任意に設定可能な識別情報を用いてインバータ装置２０の制御設定を実行しているので、インバータ装置２０を備えた制御システム１０１の構築または再構築を行う際に容易に制御設定を実行することができる。また、設定者は、既に構築済みの制御システム１０１に対しても容易に識別情報を変更することが可能となる。このように、設定者が任意に設定可能な識別情報を用いてインバータ装置２０の制御設定を実行しているので、インバータ装置２０を備えた制御システム１０１の構築または再構築を行う際の制御設定の自由度が高くなる。 Further, since the control setting of the inverter device 20 is executed using identification information which can be arbitrarily set by the setter, the control setting can be easily performed when constructing or rebuilding the control system 101 including the inverter device 20. Can be performed. In addition, the setter can easily change the identification information with respect to the control system 101 already configured. As described above, since the control setting of the inverter device 20 is executed using the identification information which can be arbitrarily set by the setter, the control setting when the control system 101 provided with the inverter device 20 is constructed or rebuilt. Degree of freedom increases.
　また、例えば、インバータ装置２０に設定された任意に設定可能な識別情報を用いて制御プログラムが事前に作成されるので、インバータ装置２０の故障またはメンテナンスのためにインバータ装置２０が交換されても、交換前と同じ識別情報を交換後のインバータ装置２０に設定することができる。このため、インバータ装置２０が交換されても、制御プログラムを編集する必要がない。 Also, for example, since a control program is created in advance using identification information settable in the inverter device 20, which can be arbitrarily set, even if the inverter device 20 is replaced for failure or maintenance of the inverter device 20, The same identification information as before replacement can be set in the inverter device 20 after replacement. Therefore, even if the inverter device 20 is replaced, there is no need to edit the control program.
　また、対応関係情報７１を用いてインバータ装置２０の制御設定を行うので、ＩＰアドレスの変更を伴う制御システム１０１の変更があった場合であっても、容易にインバータ装置２０への制御設定を行うことができる。 Further, since the control setting of the inverter device 20 is performed using the correspondence relationship information 71, the control setting to the inverter device 20 can be easily performed even when there is a change in the control system 101 accompanied by a change in IP address. be able to.
　また、識別情報を用いて制御プログラムを作成すればよいので、制御システム１０１内にインバータ装置２０または制御装置１０といった装置を配置する前から制御プログラムを作成することができる。また、ＩＰアドレスの変更を伴う制御システム１０１の変更があった場合であっても、識別情報を用いて制御プログラムを作成してあるので、制御プログラムを変更する必要がない。 In addition, since the control program may be created using the identification information, the control program can be created before the device such as the inverter device 20 or the control device 10 is disposed in the control system 101. In addition, even if there is a change in the control system 101 accompanied by a change in the IP address, the control program is created using the identification information, so there is no need to change the control program.
　このように、実施の形態１では、識別情報を用いて制御システム１０１を構築すればよいので、制御システム１０１の新設または変更といった構築を容易に行うことが可能となる。 As described above, in the first embodiment, since the control system 101 may be constructed using the identification information, construction such as addition or change of the control system 101 can be easily performed.
実施の形態２．
　つぎに、図８から図１０を用いてこの発明の実施の形態２について説明する。実施の形態２では、図２で示すインバータ装置２０が接続されているネットワークにデータベースを配置しておき、インバータ装置２０が、識別情報に基づいて、パラメータといったデータをデータベースから取得する。 Second Embodiment
Second Embodiment A second embodiment of the present invention will now be described with reference to FIGS. 8 to 10. In the second embodiment, a database is arranged in the network to which the inverter device 20 shown in FIG. 2 is connected, and the inverter device 20 acquires data such as parameters from the database based on the identification information.
　図８は、実施の形態２にかかる制御システムの構成を示す図である。図８の構成要素のうち図１に示す実施の形態１の構成要素と同一機能を達成する構成要素については同一符号を付しており、重複する説明は省略する。 FIG. 8 is a diagram showing the configuration of the control system according to the second embodiment. Among constituent elements in FIG. 8, constituent elements that achieve the same functions as those in the constituent element of the first embodiment shown in FIG. 1 are given the same reference numerals, and redundant description will be omitted.
　制御システム１０４は、移動式昇降機６０と、インバータ装置２０と、インバータ装置２０の動作を制御する制御装置１０と、インバータ装置２０が用いるパラメータを格納するデータベース８０とを備えている。ここでのインバータ装置２０は、走行用インバータ装置３０Ｐおよび昇降用インバータ装置３０Ｑである。 The control system 104 includes a mobile elevator 60, an inverter device 20, a control device 10 that controls the operation of the inverter device 20, and a database 80 that stores parameters used by the inverter device 20. The inverter device 20 here is a traveling inverter device 30P and a lifting inverter device 30Q.
　制御システム１０４が備える、移動式昇降機６０、走行用インバータ装置３０Ｐ、昇降用インバータ装置３０Ｑおよび制御装置１０は、実施の形態１の制御システム１０１が備える、移動式昇降機６０、走行用インバータ装置３０Ｐ、昇降用インバータ装置３０Ｑおよび制御装置１０と同様の機能を有している。また、制御システム１０４では、ネットワーク回線５３によってインバータ装置２０と、制御装置１０と、データベース８０とが接続されている。 The mobile elevator 60, the traveling inverter device 30P, the lifting inverter device 30Q, and the control device 10, which the control system 104 comprises, are the mobile elevator 60, the traveling inverter device 30P, which the control system 101 of the first embodiment includes. It has the same function as the lifting inverter device 30Q and the control device 10. Further, in the control system 104, the inverter device 20, the control device 10, and the database 80 are connected by the network line 53.
　記憶装置であるデータベース８０は、パラメータ記憶部８１を備えている。パラメータ記憶部８１は、インバータ装置２０が用いるパラメータを格納するメモリといった記憶装置である。パラメータ記憶部８１は、識別情報とパラメータとを対応付けした後述の対応関係情報７２を記憶している。パラメータは、インバータ装置２０が移動式昇降機６０を制御する際に用いる情報である。パラメータの例は、上限周波数、下限周波数、上限電圧値または下限電圧値といった、制御を実行する際の条件である。また、識別情報は、実施の形態１での識別情報と同様に、設定者が任意に設定可能な情報である。 A database 80 which is a storage device includes a parameter storage unit 81. The parameter storage unit 81 is a storage device such as a memory that stores parameters used by the inverter device 20. The parameter storage unit 81 stores later-described correspondence relationship information 72 in which the identification information and the parameter are associated with each other. The parameters are information used when the inverter device 20 controls the mobile elevator 60. Examples of parameters are conditions under which control is performed, such as upper limit frequency, lower limit frequency, upper limit voltage value or lower limit voltage value. Further, the identification information is information which can be arbitrarily set by the setter, similarly to the identification information in the first embodiment.
　ここで、対応関係情報７２の構成について説明する。図９は、実施の形態２にかかる対応関係情報の構成を示す図である。第２の対応関係情報である対応関係情報７２は、インバータ装置２０を識別するための識別情報と、インバータ装置２０に設定するパラメータとの対応関係がインバータ装置２０毎に設定された情報である。 Here, the configuration of the correspondence relationship information 72 will be described. FIG. 9 is a diagram showing the configuration of correspondence relationship information according to the second embodiment. The correspondence relationship information 72 which is the second correspondence relationship information is information in which the correspondence relationship between identification information for identifying the inverter device 20 and parameters set in the inverter device 20 is set for each of the inverter devices 20.
　なお、図９の対応関係情報７２では、パラメータを「Ｐｒ．」で示している。図９に示すように、対応関係情報７２では、識別情報毎に異なるパラメータが設定可能となっている。対応関係情報７２へは、識別情報毎に１つずつのパラメータが登録されてもよいし、複数のパラメータを有したパラメータセットが登録されてもよい。 In the correspondence relationship information 72 of FIG. 9, the parameters are indicated by “Pr.”. As shown in FIG. 9, in the correspondence relationship information 72, different parameters can be set for each piece of identification information. In the correspondence information 72, one parameter may be registered for each piece of identification information, or a parameter set having a plurality of parameters may be registered.
　制御システム１０４は、走行用インバータ装置３０Ｐおよび昇降用インバータ装置３０Ｑを備えている。この走行用インバータ装置３０Ｐおよび昇降用インバータ装置３０Ｑは、型名、インバータ容量およびバージョンが同一であり、同一の機能を達成可能であるものとする。走行用インバータ装置３０Ｐは、走行用のパラメータを設定する必要があり、昇降用インバータ装置３０Ｑは昇降用のパラメータを設定する必要がある。 The control system 104 includes a traveling inverter device 30P and a lifting inverter device 30Q. The driving inverter device 30P and the lifting inverter device 30Q have the same model name, inverter capacity, and version, and can achieve the same function. The traveling inverter device 30P needs to set a traveling parameter, and the lifting inverter device 30Q needs to set a lifting parameter.
　識別情報を適用しない制御システムの管理者が、型名、インバータ容量またはバージョンに基づいてインバータ装置２０を識別する場合、同一の型名、同一のインバータ容量または同一のバージョンを有したインバータ装置２０を区別することはできない。このため、識別情報を適用しない制御システムの管理者は、型名、インバータ容量またはバージョンに基づいてインバータ装置２０を識別する場合、インバータ装置２０毎にパラメータを設定する必要がある。換言すると、型名、インバータ容量またはバージョンに基づいてインバータ装置２０を識別する場合、同一の型名、同一のインバータ容量および同一のバージョンを有したインバータ装置２０へは、同一のパラメータしか設定できない。 When the administrator of the control system to which the identification information is not applied identifies the inverter device 20 based on the model name, inverter capacity or version, the inverter device 20 having the same model name, the same inverter capacity or the same version is used. It can not be distinguished. For this reason, the manager of the control system to which the identification information is not applied needs to set a parameter for each inverter device 20 when identifying the inverter device 20 based on the model name, inverter capacity or version. In other words, when identifying the inverter device 20 based on the model name, the inverter capacity or the version, only the same parameter can be set to the inverter apparatus 20 having the same model name, the same inverter capacity and the same version.
　一方、実施の形態２の制御システム１０４では、インバータ装置２０が、インバータ装置２０を個別に識別可能な識別情報を用いてパラメータを設定するので、同一の型名、同一のインバータ容量または同一のバージョンを有したインバータ装置２０であってもインバータ装置２０毎のパラメータ設定が可能となる。なお、インバータ装置２０は、識別情報に、製造番号を用いてもよい。 On the other hand, in the control system 104 according to the second embodiment, since the inverter device 20 sets parameters using identification information that can individually identify the inverter device 20, the same model name, the same inverter capacitance, or the same version The parameter setting for each inverter device 20 is possible even with the inverter device 20 having the In addition, the inverter apparatus 20 may use a serial number for identification information.
　なお、対応関係情報７２は、データベース８０の管理者が作成してもよいし、インバータ装置２０の使用者が作成してもよい。また、対応関係情報７２の作成は、データベース８０の出荷前であってもよいし、データベース８０の出荷後であってもよい。また、対応関係情報７２の作成は、インバータ装置２０の出荷前であってもよいし、インバータ装置２０の出荷後であってもよい。 The correspondence relationship information 72 may be created by the administrator of the database 80 or may be created by the user of the inverter device 20. Further, the creation of the correspondence relationship information 72 may be before shipment of the database 80 or may be after shipment of the database 80. The correspondence relationship information 72 may be created before shipment of the inverter device 20 or after shipment of the inverter device 20.
　つぎに、パラメータのインバータ装置２０への設定処理手順について説明する。図１０は、実施の形態２にかかるインバータ装置のパラメータ設定処理手順を示すフローチャートである。 Below, the setting process procedure to the inverter apparatus 20 of a parameter is demonstrated. FIG. 10 is a flowchart of a parameter setting process procedure of the inverter device according to the second embodiment.
　インバータ装置２０は、予め識別情報を記憶しておく。また、データベース８０は、予め対応関係情報７２を記憶しておく。この後、ステップＳ２１０において、インバータ装置２０が、自装置の識別情報に対応するパラメータをデータベース８０からダウンロードする。このとき、インバータ装置２０は、対応関係情報７２の中から自装置の識別情報と同じ識別情報に対応付けされたパラメータを指定して、データベース８０からパラメータをダウンロードする。そして、ステップＳ２２０において、インバータ装置２０は、ダウンロードしたパラメータを自装置に設定する。 The inverter device 20 stores identification information in advance. Moreover, the database 80 stores the correspondence relationship information 72 in advance. Thereafter, in step S210, the inverter device 20 downloads a parameter corresponding to the identification information of the own device from the database 80. At this time, the inverter device 20 specifies a parameter associated with the same identification information as the identification information of the own device from among the correspondence relationship information 72, and downloads the parameter from the database 80. Then, in step S220, the inverter device 20 sets the downloaded parameter in its own device.
　なお、インバータ装置２０は、インバータ装置２０の使用者からの指示に従ってパラメータをデータベース８０からダウンロードしてもよいし、データベース８０から自動的にダウンロードしてもよい。インバータ装置２０が自動的にパラメータをダウンロードする場合のダウンロードタイミングとしては、以下の（１）から（４）が考えられる。
（１）インバータ装置２０の電源投入後
（２）データベース８０内のパラメータが更新された時
（３）識別情報が変更された時
（４）参照すべきデータベース８０が変更された時 The inverter device 20 may download the parameter from the database 80 according to an instruction from the user of the inverter device 20, or may automatically download the parameter from the database 80. The following (1) to (4) can be considered as the download timing when the inverter device 20 automatically downloads the parameter.
(1) After power-on of the inverter device 20 (2) when parameters in the database 80 are updated (3) when identification information is changed (4) when the database 80 to be referred to is changed
　（２）の場合、インバータ装置２０は、データベース８０に対してパラメータの更新状況を監視しておく。この場合、制御システム１０４は、データベース８０内のパラメータが更新されれば、このパラメータを使用するインバータ装置２０のパラメータを自動的にまとめて更新できる。また、（３）の場合、インバータ装置２０の適用先を変更する際に、識別情報を変更するだけで、パラメータの自動設定が行われるので、インバータ装置２０の適用先を容易に変更できる。例えば、走行用インバータ装置３０Ｐを昇降用インバータ装置３０Ｑに変更する際に、昇降用インバータ装置３０Ｑに用いる識別情報を設定するだけで、昇降用インバータ装置３０Ｑにパラメータを自動設定できる。 In the case of (2), the inverter device 20 monitors the update status of the parameter with respect to the database 80. In this case, if the parameter in the database 80 is updated, the control system 104 can automatically collectively update the parameters of the inverter device 20 using this parameter. Further, in the case of (3), when the application destination of the inverter device 20 is changed, the parameter setting is automatically performed only by changing the identification information, so the application destination of the inverter device 20 can be easily changed. For example, when changing the traveling inverter device 30P to the raising and lowering inverter device 30Q, parameters can be automatically set in the raising and lowering inverter device 30Q simply by setting identification information used for the raising and lowering inverter device 30Q.
　なお、識別情報は、インバータ装置２０のメーカーが、ユーザの要求に応じて、出荷までに設定しておいてもよい。また、インバータ装置２０の電源投入時に、インバータ装置２０がパラメータを自動ダウンロードするように設定しておいてもよい。この場合、データベース８０内にパラメータを格納しておけば、インバータ装置２０の電源投入だけでインバータ装置２０へのパラメータ設定を実行できる。 The identification information may be set by the manufacturer of the inverter device 20 before shipment according to the user's request. Further, the inverter device 20 may be set to automatically download the parameter when the power of the inverter device 20 is turned on. In this case, if parameters are stored in the database 80, parameter setting to the inverter device 20 can be performed only by turning on the power of the inverter device 20.
　制御システム１０４においては、個々のインバータ装置２０に直接設定されるのは識別情報のみである。また、識別情報に基づいてアクセスされるデータベース８０は、全てのインバータ装置２０に対して同一のアクセス許可設定をすればよい。また、データベース８０に格納するパラメータは、識別情報毎にデータベース８０側で設定すればよい。 In the control system 104, only identification information is directly set in each inverter device 20. Moreover, the database 80 accessed based on identification information should just set the same access permission with respect to all the inverter apparatuses 20. FIG. The parameters stored in the database 80 may be set on the database 80 side for each identification information.
　また、データベース８０は、イーサネットといったネットワークを用いたネットワーク回線５３を経由してインバータ装置２０にアクセスされるので、インバータ装置２０と同一の工場内、インバータ装置２０と同一の社内、工場の外部または社外の何れの位置に配置されてもよい。 Further, since the database 80 is accessed by the inverter device 20 via the network line 53 using a network such as Ethernet, the same factory as the inverter device 20, the same company as the inverter device 20, the outside of the factory or the outside of the factory. It may be arranged at any position of
　例えば、データベース８０は、インバータ装置２０のメーカーが管理しているメーカーサーバに配置されてもよいし、ユーザが管理しているユーザサーバに配置されてもよい。インバータ装置２０を出荷する際にメーカーサーバを参照する設定となっている場合には、メーカーサーバ上のパラメータに、参照先をユーザサーバに変更する参照パラメータを設定しておけばよい。これにより、インバータ装置２０は、パラメータの参照先をユーザサーバに切り替えることができる。また、インバータ装置２０を出荷する際に、最初からユーザサーバを参照するように参照パラメータを設定しておいてもよい。なお、インバータ装置２０とデータベース８０とは、中継装置を介して接続されてもよい。この場合、インバータ装置２０はネットワーク回線５３とは別のネットワーク回線に接続されてもよい。 For example, the database 80 may be arranged in a maker server managed by the maker of the inverter device 20 or may be arranged in a user server managed by a user. When the manufacturer server is set to be referred to when the inverter device 20 is shipped, a reference parameter for changing the reference destination to the user server may be set as the parameter on the maker server. Thereby, the inverter apparatus 20 can switch the reference destination of a parameter to a user server. Further, when the inverter device 20 is shipped, the reference parameter may be set to refer to the user server from the beginning. The inverter device 20 and the database 80 may be connected via a relay device. In this case, the inverter device 20 may be connected to a network line different from the network line 53.
　このように、実施の形態２によれば、インバータ装置２０が識別情報に基づいて、データベース８０から自装置用のパラメータをダウンロードするので、インバータ装置２０は容易にパラメータを設定することができる。 As described above, according to the second embodiment, since the inverter device 20 downloads the parameter for the own device from the database 80 based on the identification information, the inverter device 20 can easily set the parameter.
　また、インバータ装置２０は、初回の電源投入後、即座に識別情報を受付けるモードに入るようにしておけば、インバータ装置２０は、起動後すぐに識別情報に基づいたパラメータをダウンロードすることが可能となる。これにより、インバータ装置２０は、容易にパラメータを設定することができる。また、インバータ装置２０に対しては識別情報を設定できればよいので、インバータ装置２０側でのパラメータの設定に必要な操作を簡略化することができる。 In addition, when the inverter device 20 is made to enter the mode for receiving identification information immediately after the power is turned on for the first time, the inverter device 20 can download the parameter based on the identification information immediately after startup. Become. Thus, the inverter device 20 can easily set the parameters. Further, as long as identification information can be set for the inverter device 20, an operation necessary for setting parameters on the inverter device 20 side can be simplified.
　また、インバータ装置２０のメーカーが、個々のインバータ装置２０を出荷する前に、ユーザからの要求に対応する識別情報をインバータ装置２０に設定しておいてもよい。この場合、ユーザがインバータ装置２０をネットワーク回線５３に接続してインバータ装置２０に電源を投入するだけで、インバータ装置２０は、適切なパラメータをダウンロードすることができる。また、ネットワーク回線５３がイーサネットでありＤＨＣＰ機能が有効であれば、インバータ装置２０側でのパラメータの設定が不要となる。 In addition, the manufacturer of the inverter device 20 may set identification information corresponding to the request from the user in the inverter device 20 before shipping each inverter device 20. In this case, the inverter device 20 can download appropriate parameters only by the user connecting the inverter device 20 to the network line 53 and turning on the power to the inverter device 20. In addition, if the network line 53 is Ethernet and the DHCP function is valid, setting of parameters on the side of the inverter device 20 becomes unnecessary.
　ここで、インバータ装置２０および制御装置１０のハードウェア構成について説明する。なお、インバータ装置２０および制御装置１０は、同様のハードウェア構成を有しているので、ここではインバータ装置２０のハードウェア構成について説明する。 Here, hardware configurations of the inverter device 20 and the control device 10 will be described. Since inverter device 20 and control device 10 have the same hardware configuration, the hardware configuration of inverter device 20 will be described here.
　図１１は、実施の形態１，２にかかるインバータ装置のハードウェア構成例を示す図である。インバータ装置２０は、図１１に示した制御回路３００、すなわちプロセッサ３０１およびメモリ３０２により実現することができる。プロセッサ３０１の例は、ＣＰＵ（Central　Processing　Unit、中央処理装置、処理装置、演算装置、マイクロプロセッサ、マイクロコンピュータ、ＤＳＰともいう）またはシステムＬＳＩ（Large　Scale　Integration）である。メモリ３０２の例は、ＲＡＭ（Random　Access　Memory）、またはＲＯＭ（Read　Only　Memory）である。 FIG. 11 is a diagram illustrating an example of a hardware configuration of the inverter device according to the first and second embodiments. The inverter device 20 can be realized by the control circuit 300 shown in FIG. 11, that is, the processor 301 and the memory 302. An example of the processor 301 is a CPU (Central Processing Unit, central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, also referred to as DSP) or a system LSI (Large Scale Integration). An example of the memory 302 is a random access memory (RAM) or a read only memory (ROM).
　インバータ装置２０は、プロセッサ３０１が、インバータ装置２０の動作を実行するためのプログラムをメモリ３０２から読み出して実行することにより実現される。また、このプログラムは、インバータ装置２０の手順または方法をコンピュータに実行させるものであるともいえる。メモリ３０２は、プロセッサ３０１が各種処理を実行する際の一時メモリにも使用される。 The inverter device 20 is realized by the processor 301 reading out a program for executing the operation of the inverter device 20 from the memory 302 and executing the program. Also, it can be said that this program causes a computer to execute the procedure or method of the inverter device 20. The memory 302 is also used as a temporary memory when the processor 301 executes various processes.
　プロセッサ３０１が実行するプログラムは、プログラムが格納された記録媒体であるコンピュータプログラムプロダクトで実現されてもよい。この場合の記録媒体の例は、プログラムが格納された非一時的な（non-transitory）コンピュータ可読媒体である。 The program executed by the processor 301 may be realized by a computer program product which is a recording medium storing the program. An example of the recording medium in this case is a non-transitory computer readable medium in which the program is stored.
　また、インバータ装置２０を専用のハードウェアで実現してもよい。また、インバータ装置２０の機能について、一部を専用のハードウェアで実現し、一部をソフトウェアまたはファームウェアで実現するようにしてもよい。 Also, the inverter device 20 may be realized by dedicated hardware. Further, a part of the functions of the inverter device 20 may be realized by dedicated hardware and a part may be realized by software or firmware.
