The data is collected by the parent machine and recorded in the memory, and the data collected by the production management monitor parent machine is analyzed, determined, and displayed to notify the operator of delays in production schedules and machine abnormalities.

生産管理モニター子機は各機械に取り付けられており、ハード構成としては中央演算処理装置（以後CPUという）と、機械側からの稼働情報を検出及び出力する入出力装置（以後Ｉ／Ｏという）と、通信装置より成り立っている。ソフト構成としては、機械から検出した稼働状況のデータを生産管理モニター親機と通信する通信機能をＣＰＵが制御し、入出力データとして管理されたデータを生産管理モニター親機と通信する機能を持つ。   The production management monitor slave unit is attached to each machine. As a hardware configuration, a central processing unit (hereinafter referred to as CPU) and an input / output device (hereinafter referred to as I / O) that detects and outputs operation information from the machine side. And a communication device. As a software configuration, the CPU controls the communication function for communicating the operation status data detected from the machine with the production management monitor master unit, and has the function of communicating the data managed as input / output data with the production management monitor master unit .

生産管理モニター親機は所定の生産ラインや所定の管理ブロックにそれぞれ配置されており、複数の生産管理モニター子機と通信を行う。ハード構成としては、CPUと、通信装置と、記憶装置（以後メモリという）より成り立っている。ソフト構成としては、生産管理モニター子機から送られてくるデータをチャンネルを切り替えることでそれぞれの生産管理モニター子機のデータを集計し、メモリに記憶させておく構成と、集計した稼働状況のデータをデータ解析装置または、生産管理モニター子機と通信する通信機能をＣＰＵが制御し、データ解析装置及び生産管理モニター子機との通信機能を持つ。   The production management monitor master unit is arranged in a predetermined production line or a predetermined management block, and communicates with a plurality of production management monitor slave units. The hardware configuration includes a CPU, a communication device, and a storage device (hereinafter referred to as a memory). As software configuration, the data of each production management monitor slave unit is aggregated by switching the channel of the data sent from the production management monitor slave unit and stored in the memory, and the aggregated operation status data The CPU controls a communication function for communicating with the data analysis device or the production management monitor slave unit, and has a communication function with the data analysis device and the production management monitor slave unit.

データ解析装置は、各生産管理モニター親機の集計したデータを解析し、前もって入力されている生産予定などのデータと照らし合わせて判定を行うとともに、管理者及び作業者に生産の進捗状況を表示して伝達する。また、機械に異常が発生したと判定された場合には異常の発生した機械を特定し、表示する。ハード構成としては、CPUと、通信装置と、メモリと、表示装置より成り立っている。ソフト構成としては、生産管理モニター親機から送られてくるデータをチャンネルを切り替えることでそれぞれの生産管理モニター子機のデータを集計し、メモリに記憶させておく構成と、集計した稼働状況のデータを決められた方法により解析・判定を行い、表示装置に表示する。   The data analysis device analyzes the data collected by each production management monitor master unit, makes a judgment against the data such as the production schedule that has been input in advance, and displays the progress of production to the manager and the operator. Then communicate. If it is determined that an abnormality has occurred in the machine, the machine in which the abnormality has occurred is identified and displayed. The hardware configuration includes a CPU, a communication device, a memory, and a display device. As software configuration, the data of each production management monitor slave unit is aggregated by switching the channel of the data sent from the production management monitor master unit and stored in the memory, and the aggregated operation status data Is analyzed and determined by a predetermined method and displayed on the display device.

従来は図１に示すように、各生産管理モニターにデータメモリ集計や解析・判定・メモリ機能がついており、単独の機械の生産管理については全ての機能がついているので使いやすいが、工場や生産ライン単位での管理を考えた場合、機械の数が多くなるためチャンネルを多く必要とする。また、通信量が多くなるという問題もあったが、生産管理モニターを親機と子機に分けることにより、チャンネル数の問題と通信量の問題が改善された。 Conventionally, as shown in Fig. 1, each production management monitor has data memory aggregation, analysis, judgment, and memory functions, and it is easy to use because all functions are attached to the production management of a single machine. Considering line-by-line management, the number of machines increases, so many channels are required. In addition, there was a problem that the amount of communication increased, but the problem of the number of channels and the amount of communication were improved by dividing the production management monitor into a master unit and a slave unit.

図３の実施例は、生産管理モニター親機及び生産管理モニター子機に表示機能を持たせた例である。生産管理システムで生産の進捗状況を管理するためにはデータ解析装置の表示装置に表示される表や色により進捗の度合いを見る方法が一般的である。また、異常のある機械については特記事項として表示され、管理者及び作業者に注意を促す。   The embodiment of FIG. 3 is an example in which a display function is provided to the production management monitor master unit and the production management monitor slave unit. In order to manage the progress of production by the production management system, a method of checking the degree of progress by a table or color displayed on the display device of the data analysis device is generally used. In addition, abnormal machines are displayed as special notes and alert the administrator and the operator.

しかし、データ解析装置の表示装置から離れた位置に作業者がいる場合は表示装置を見ることができないため、生産管理モニター親機又は生産管理モニター子機に異常を知らせる表示装置を取り付けた。表示装置はディスプレーのような画面やシグナルタワーのような色による表示灯を用い、作業者が判別しやすいようにする。   However, when the worker is at a position away from the display device of the data analysis device, the display device cannot be seen. Therefore, a display device for notifying the production management monitor master unit or the production management monitor slave unit is attached. The display device uses a screen like a display and an indicator lamp with a color like a signal tower so that the operator can easily identify it.

本発明は、加工機械のラインに用いられるが、組立ラインや梱包ラインのような生産管理システムを用いたところでも適用できる。   The present invention is used for a line of a processing machine, but can also be applied to a place using a production management system such as an assembly line or a packing line.
