国際公開第2014/181423号International Publication No. 2014/181423
 この先行技術では、情報表示端末装置の表示画面に生産装置の稼働状態を表示する構成であり、管理者が情報表示端末装置の前にいて複数の生産装置の稼働状態を一括して監視できる。 In this prior art, the operation state of the production apparatus is displayed on the display screen of the information display terminal device, and an administrator can monitor the operation state of a plurality of production devices in front of the information display terminal device.
 しかし、管理者が情報表示端末装置の近くにいて、表示画面に対面する必要があるから、管理者の位置が大きく制約され、管理者が他の作業に従事しながら同時に管理を行うような場合には、必ずしも便利ではない。 However, when the administrator is close to the information display terminal device and needs to face the display screen, the position of the administrator is greatly restricted, and the administrator is engaged in other work and manages at the same time Is not always convenient.
 そこで、この発明は、利便性の向上された信号表示灯システム、および信号表示灯システムのための信号表示灯を提供する。 Therefore, the present invention provides a signal indicator lamp system with improved convenience and a signal indicator lamp for the signal indicator lamp system.
 この発明は、それぞれ表示部を有する複数の信号表示灯が通信ネットワークを介して通信可能に接続された信号表示灯システムを提供する。この信号表示灯システムでは、前記複数の信号表示灯のうちの第1の信号表示灯が、前記複数の信号表示灯のうちの前記第1の信号表示灯とは別の第2の信号表示灯から情報を得て作動する。前記第1の信号表示灯は、前記第2の信号表示灯から、当該第2の信号表示灯の表示状態に対応する表示状態情報を前記通信ネットワークを介して取得する手段と、前記取得された表示状態情報に基づいて、当該表示状態情報に対応し、かつ前記第2の信号表示灯とは異なる表示状態に当該第1の信号表示灯の前記表示部を制御する表示制御手段と、を含む。前記第2の信号表示灯は、当該第2の信号表示灯の表示状態に対応する表示状態情報を前記通信ネットワークを介して前記第1の信号表示灯に送信する手段を含む。 This invention provides a signal indicator lamp system in which a plurality of signal indicator lamps each having a display unit are connected to be communicable via a communication network. In this signal indicator lamp system, a first signal indicator lamp of the plurality of signal indicator lamps is a second signal indicator lamp different from the first signal indicator lamp of the plurality of signal indicator lamps. Operates with information from. The first signal indicator lamp is configured to acquire, from the second signal indicator lamp, display state information corresponding to a display state of the second signal indicator lamp via the communication network; Display control means for controlling the display unit of the first signal indicator lamp in a display state corresponding to the display state information and different from the second signal indicator lamp based on the display state information. . The second signal indicator lamp includes means for transmitting display state information corresponding to the display state of the second signal indicator lamp to the first signal indicator lamp via the communication network.
 この構成により、第1の信号表示灯は、第2の信号表示灯から情報を得て動作し、第2の信号表示灯の表示状態に対応する表示状態に制御される。したがって、使用者は、第1の信号表示灯を目視することによって、第2の信号表示灯で報知されている情報を知ることができる。第1の信号表示灯による表示は、情報表示端末装置の表示画面上での表示とは異なり、使用者が表示画面の近くで当該表示画面に対面することを要しない。すなわち、使用者は、第1の信号表示灯が目視できる限りにおいて、自由な位置から第1の信号表示灯の表示状態を確認できる。それにより、使用者の位置に関する制約が大幅に減じられ、たとえば、使用者は、他の作業に従事しながら同時に第1の信号表示灯を目視し、それによって、第2の信号表示灯で報知されている情報を知ることができる。こうして、利便性に優れた信号表示灯システムを提供できる。 With this configuration, the first signal indicator lamp operates by obtaining information from the second signal indicator lamp, and is controlled to a display state corresponding to the display state of the second signal indicator lamp. Therefore, the user can know the information notified by the second signal indicator by observing the first signal indicator. Unlike the display on the display screen of the information display terminal device, the display by the first signal indicator does not require the user to face the display screen near the display screen. That is, the user can confirm the display state of the first signal indicator lamp from a free position as long as the first signal indicator lamp is visible. As a result, restrictions on the position of the user are greatly reduced. For example, the user visually observes the first signal indicator lamp while engaging in other work, thereby informing the user with the second signal indicator lamp. You can know the information that has been. Thus, it is possible to provide a signal display lamp system that is highly convenient.
 さらに、この発明では、第1の信号表示灯の表示状態は、第2の信号表示灯の表示状態に対応するものの、第2の信号表示灯の表示状態とは異なる状態となる。これにより、第2の信号表示灯によって報知されている情報を、第1の信号表示灯を目視する使用者にとってより適切な形式で表示して提供することができる。たとえば、第2の信号表示灯が、生産装置その他の機械装置の稼働状況を当該機械装置の近傍で表示する場合を考える。この場合、第2の信号表示灯を目視するのは現場作業者であるので、第2の信号表示灯は現場作業者が必要とする詳細情報を表示するのが適切である。その一方で、第1の信号表示灯は、工場の全体的な稼働状況を管理する管理者に目視されるとすれば、第1の信号表示灯において第2の信号表示灯の表示状態をそのまま再現すると、提供される情報が詳細過ぎて、不必要な情報までもが管理者に提供されるおそれがある。そこで、第1の信号表示灯の表示状態を第2の信号表示灯の表示状態とは異ならせ、第1の信号表示灯では、管理者が必要とする情報に限定して提供する表示状態とすることが適切である場合がある。この発明は、このような状況での課題に対する解決手段を提供し、利便性に優れた信号表示灯システムを提供する。 Furthermore, in the present invention, the display state of the first signal indicator lamp corresponds to the display state of the second signal indicator lamp, but is different from the display state of the second signal indicator lamp. Thereby, the information notified by the second signal indicator lamp can be displayed and provided in a more appropriate format for the user who views the first signal indicator lamp. For example, let us consider a case where the second signal indicator lamp displays the operating status of the production apparatus and other mechanical devices in the vicinity of the mechanical device. In this case, since it is a field worker who looks at the second signal indicator lamp, it is appropriate that the second signal indicator lamp displays detailed information required by the field worker. On the other hand, if the first signal indicator lamp is viewed by an administrator who manages the overall operation status of the factory, the display state of the second signal indicator lamp remains as it is in the first signal indicator lamp. If reproduced, the information provided is too detailed, and even unnecessary information may be provided to the administrator. Therefore, the display state of the first signal indicator lamp is different from the display state of the second signal indicator lamp, and the first signal indicator lamp provides a display state limited to information required by the administrator. It may be appropriate to do so. The present invention provides a solution to the problem in such a situation, and provides a signal indicator lamp system that is excellent in convenience.
 この発明の一実施形態では、前記第1の信号表示灯が、複数の前記第2の信号表示灯の表示状態を集約して表示するように動作し、前記表示制御手段が、複数の前記第2の信号表示灯の表示状態情報に基づいて、当該第1の信号表示灯の前記表示部を制御するように構成されている。 In one embodiment of the present invention, the first signal indicator lamp operates to collect and display the display states of the plurality of second signal indicator lamps, and the display control means includes a plurality of the first indicator lights. Based on the display state information of the second signal indicator lamp, the display unit of the first signal indicator lamp is controlled.
 この構成により、複数の第2の信号表示灯の表示状態を集約した表示が第1の信号表示灯によって提供される。それにより、第1の信号表示灯を目視する使用者は、その表示状態から、複数の第2の信号表示灯が報知している情報を得ることができる。 With this configuration, a display in which the display states of the plurality of second signal indicator lamps are aggregated is provided by the first signal indicator lamp. Thereby, the user who views the first signal indicator lamp can obtain the information notified by the plurality of second signal indicator lamps from the display state.
 この発明の一実施形態では、前記第1の信号表示灯が、前記複数の第2の信号表示灯の表示状態情報の組合せに基づいて前記第1の信号表示灯の表示部の表示状態を決定する表示状態決定手段を含み、前記表示制御手段が、前記表示状態決定手段によって決定される表示状態に前記第1の信号表示灯の前記表示部を制御する。 In one embodiment of the present invention, the first signal indicator lamp determines the display state of the display portion of the first signal indicator lamp based on a combination of display state information of the plurality of second signal indicator lamps. The display control means controls the display section of the first signal indicator lamp to the display state determined by the display state determination means.
 この構成により、第1の信号表示灯の表示状態は、複数の第2の信号表示灯の表示状態を適切に集約表示した状態となる。それにより、第1の信号表示灯によって、複数の第2の信号表示灯が報知している情報を適切に報知できる。 With this configuration, the display state of the first signal indicator lamp is a state in which the display states of the plurality of second signal indicator lamps are appropriately aggregated and displayed. Thereby, the information which the some 2nd signal indicator lamp alert | reports can be alert | reported appropriately by the 1st signal indicator lamp.
 この発明の一実施形態では、前記第2の信号表示灯の表示状態が、第1段階異常表示状態と、第1段階異常表示状態よりも高い異常状態を表示する第2段階異常表示状態とを含み、前記表示制御手段が、前記複数の第2の信号表示灯の表示状態の異常表示段階の組合せによって規定される表示状態で前記第1の信号表示灯の表示部を制御する。 In one embodiment of the present invention, the display state of the second signal indicator lamp includes a first stage abnormality display state and a second stage abnormality display state displaying an abnormal state higher than the first stage abnormality display state. In addition, the display control means controls the display unit of the first signal indicator lamp in a display state defined by a combination of abnormal display stages of the display states of the plurality of second signal indicator lamps.
 この構成により、複数の第2の信号表示灯で報知されている異常状態の全体的な状況を第1の信号表示灯で集約して表示して報知できる。それにより、たとえば、全体の状況を管理する管理者は、第1の信号表示灯の表示によって必要な情報を得ることができる。たとえば、個々の生産装置その他の機械装置等で生じている軽微な異常状態は、現場責任者の判断で対応可能な場合もあるから、全体管理者には必ずしも伝える必要がない。その一方で、複数の生産装置で異常が発生していたり、重度の異常が生じていたりするような状況は、全体管理者が把握しておくべき場合もある。そこで、複数の第2の信号表示灯の異常表示段階の組合せが第1の信号表示灯において表現されることにより、全体管理者は、必要とする情報を適切に得ることができる。 With this configuration, it is possible to collect and display the overall state of the abnormal state that has been notified by the plurality of second signal indicator lamps by using the first signal indicator lamp. Thereby, for example, an administrator who manages the entire situation can obtain necessary information by displaying the first signal indicator lamp. For example, a minor abnormal state occurring in an individual production device or other mechanical device may be able to be dealt with at the discretion of the site manager, and therefore it is not always necessary to communicate to the general manager. On the other hand, there may be a case where the general manager should know the situation in which an abnormality has occurred in a plurality of production apparatuses or a serious abnormality has occurred. Thus, the combination of abnormal display stages of the plurality of second signal indicator lamps is expressed in the first signal indicator lamp, so that the general manager can appropriately obtain necessary information.
 この発明の一実施形態では、前記表示部が、個別に表示状態が変更可能な複数の表示制御要素を含み、前記表示制御手段が、複数の前記第2の信号表示灯に対して複数の前記表示制御要素をそれぞれ対応付けて、前記複数の第2の信号表示灯のそれぞれの表示状態情報に応じて、対応する前記表示制御要素の表示状態を制御する。 In one embodiment of the present invention, the display unit includes a plurality of display control elements whose display states can be individually changed, and the display control means includes a plurality of the second signal indicator lamps. The display control elements are associated with each other, and the display states of the corresponding display control elements are controlled according to the display state information of the plurality of second signal indicator lamps.
 この構成では、複数の第2の信号表示灯によって報知されている情報が、第1の信号表示灯に備えられる複数の表示制御要素によってそれぞれ表現されて報知される。それにより、使用者は、第1の信号表示灯を目視することにより、複数の第2の信号表示灯が報知している情報を一括して得ることができる。 In this configuration, information notified by the plurality of second signal indicator lamps is expressed and notified by the plurality of display control elements provided in the first signal indicator lamp. Thereby, the user can obtain the information which the some 2nd signal indicator lamp alert | reported collectively by observing a 1st signal indicator lamp.
 この発明の一実施形態では、前記複数の第2の信号表示灯の表示状態が、それぞれに対応する監視対象の数量(数、量、度数等)を表す表示状態である。 In one embodiment of the present invention, the display state of the plurality of second signal indicator lamps is a display state representing the quantity (number, quantity, frequency, etc.) of the monitoring target corresponding to each.
 この場合、第1の信号表示灯では、複数の第2の信号表示灯が表示している数量の総量や平均量等が表示されてもよい。それにより、第1の信号表示灯は、複数の監視対象の全体的な数量を表示でき、使用者(とくに管理者)に対して、適切な情報を提供できる。 In this case, the first signal indicator lamp may display the total quantity or the average quantity of the quantities displayed by the plurality of second signal indicator lamps. Thereby, the 1st signal indicator lamp can display the whole quantity of a plurality of monitoring objects, and can provide suitable information to a user (especially manager).
 たとえば、第1および第2の信号表示灯は、表示部における表示領域の大きさ、表示色、点滅表示時間間隔等によって、数量を表現する表示が行われてもよい。 For example, the first and second signal indicator lamps may be displayed to express the quantity depending on the size of the display area in the display unit, the display color, the blinking display time interval, and the like.

 図3は、信号表示灯1,100の電気的構成例を説明するためのブロック図である。信号表示灯1,100は、表示部12と、制御ユニット15と、スピーカ16と、ネットワークインタフェース17とを含む。表示部12、スピーカ16およびネットワークインタフェース17は、制御ユニット15に接続され、制御ユニット15によって制御される。制御ユニット15は、主制御ユニットとしてのCPU(中央処理ユニット)50と、表示部12を制御するための表示部駆動ユニット51と、スピーカ16を駆動するためのスピーカ駆動ユニット52と、入力回路53と、メモリ54とを含む。入力回路53には、入力信号線8が接続される。ただし、管理用信号表示灯100は、入力信号線8からの入力信号の受付けを必要としないので、入力回路53が備えられていなくてもよい。メモリ54は、EEPROM(電気的に消去・書込可能な読出し専用メモリ)等の不揮発性メモリ55とRAM(ランダムアクセスメモリ)56とを含んでいてもよい。不揮発性メモリ55には、CPU50が実行する実行プログラムや、各種制御パラメータが格納されている。CPU50は、RAM56の記憶領域を作業領域として用いながら、不揮発性メモリ55に格納されている実行プログラムを実行し、それによって、複数の機能処理部として機能する。メモリ54は、表示部12の表示制御のために用いる表示制御情報を記憶する表示制御情報記憶手段の一例である。表示制御情報は、不揮発性メモリ55に格納されてもよいし、RAM56(揮発性メモリ)に格納されてもよい。電源遮断後にも表示制御情報を保持すべきときには、不揮発性メモリ55に表示制御情報が格納されることが好ましい。以下では、主として、表示制御情報が不揮発性メモリ55に格納される場合について説明する。 FIG. 3 is a block diagram for explaining an example of the electrical configuration of the signal indicator lamp 1,100. The signal lamps 1 and 100 include a display unit 12, a control unit 15, a speaker 16, and a network interface 17. The display unit 12, the speaker 16, and the network interface 17 are connected to the control unit 15 and controlled by the control unit 15. The control unit 15 includes a CPU (central processing unit) 50 as a main control unit, a display unit drive unit 51 for controlling the display unit 12, a speaker drive unit 52 for driving the speaker 16, and an input circuit 53. And a memory 54. An input signal line 8 is connected to the input circuit 53. However, since the management signal indicator lamp 100 does not need to accept an input signal from the input signal line 8, the input circuit 53 may not be provided. The memory 54 may include a nonvolatile memory 55 such as an EEPROM (electrically erasable / writable read-only memory) and a RAM (random access memory) 56. The nonvolatile memory 55 stores an execution program executed by the CPU 50 and various control parameters. The CPU 50 executes the execution program stored in the nonvolatile memory 55 while using the storage area of the RAM 56 as a work area, thereby functioning as a plurality of function processing units. The memory 54 is an example of a display control information storage unit that stores display control information used for display control of the display unit 12. The display control information may be stored in the nonvolatile memory 55 or may be stored in the RAM 56 (volatile memory). When the display control information should be retained even after the power is turned off, the display control information is preferably stored in the nonvolatile memory 55. Hereinafter, a case where display control information is stored in the nonvolatile memory 55 will be mainly described.
 CPU50は、表示部駆動ユニット51に表示制御信号を与える表示制御部501(表示制御手段の一例)として機能する。表示部駆動ユニット51は、表示制御信号に応じて表示部12を構成する各表示ユニット20の光源30を駆動し、各光源30の発光状態(発光色および点灯/消灯)を制御する。また、CPU50は、スピーカ駆動ユニット52に発音制御信号を与える発音制御部502として機能する。スピーカ駆動ユニット52は、発音制御信号に応じてスピーカ16を駆動し、音声を発生させる。さらに、CPU50は、ネットワークインタフェース17を介する通信(すなわち、送信および受信)を制御するための通信制御部503(送信制御部および受信制御部)として機能する。さらにまた、CPU50は、入力信号線8から入力回路53に入力される入力信号を受け付ける入力受付部504(入力信号受付手段の一例)として機能する。これらの機能処理部は、概念的な区分であって、CPU50が物理的にこのような機能処理部に分かれている必要はなく、CPU50が実行する実行プログラムが前記機能処理部に該当する区分を有している必要もない。 The CPU 50 functions as a display control unit 501 (an example of a display control unit) that provides a display control signal to the display unit drive unit 51. The display unit drive unit 51 drives the light source 30 of each display unit 20 constituting the display unit 12 in accordance with the display control signal, and controls the light emission state (light emission color and lighting / extinction) of each light source 30. Further, the CPU 50 functions as a sound generation control unit 502 that supplies a sound generation control signal to the speaker drive unit 52. The speaker driving unit 52 drives the speaker 16 according to the sound generation control signal and generates sound. Further, the CPU 50 functions as a communication control unit 503 (transmission control unit and reception control unit) for controlling communication (that is, transmission and reception) via the network interface 17. Furthermore, the CPU 50 functions as an input receiving unit 504 (an example of an input signal receiving unit) that receives an input signal input from the input signal line 8 to the input circuit 53. These function processing units are conceptual divisions, and it is not necessary for the CPU 50 to be physically divided into such functional processing units, and the execution program executed by the CPU 50 is classified into the functional processing units. It is not necessary to have it.
 制御ユニット15は、さらに、時間を計測するタイマ58を含む。CPU50は、必要に応じてタイマ58の計時時間を参照しながら、処理を実行する。 The control unit 15 further includes a timer 58 that measures time. The CPU 50 executes processing while referring to the time measured by the timer 58 as necessary.
 この実施形態の信号表示灯システムは、管理用信号表示灯100において、生産装置A~Cに接続された信号表示灯1における表示を模擬させる動作であるミラーリング動作が可能に構成されている。ただし、この実施形態では、管理用信号表示灯100は、必ずしも信号表示灯1と同じ表示状態に制御されるわけではなく、信号表示灯1の表示状態とは異なる表示状態に制御される場合もある。たとえば、信号表示灯1は、個々の生産装置A~Cの現場担当者が知るべき詳細情報を表示するのに対して、管理用信号表示灯100は、管理者に伝達されるべき情報を適切に表示するように制御される。このようなミラーリング動作を用いることにより、管理用信号表示灯100の近くにいる管理者は、個々の生産装置A~Cの近くまで移動することなく、生産装置A~Cの稼働状態に関して必要な情報を適切に得ることができる。ミラーリング動作は、情報処理端末装置10によって、信号表示灯1,100の動作を設定することによって達成される。 The signal indicator lamp system of this embodiment is configured such that the management signal indicator lamp 100 can perform a mirroring operation, which is an operation for simulating the display on the signal indicator lamp 1 connected to the production apparatuses A to C. However, in this embodiment, the management signal indicator lamp 100 is not necessarily controlled to the same display state as the signal indicator lamp 1, and may be controlled to a display state different from the display state of the signal indicator lamp 1. is there. For example, the signal indicator lamp 1 displays detailed information to be known by the on-site person in charge of each production apparatus A to C, whereas the management signal indicator lamp 100 appropriately displays information to be transmitted to the manager. It is controlled to be displayed. By using such a mirroring operation, an administrator near the management signal indicator lamp 100 is necessary for the operating state of the production apparatuses A to C without moving to the vicinity of the individual production apparatuses A to C. Information can be obtained appropriately. The mirroring operation is achieved by setting the operation of the signal indicator lamps 1 and 100 by the information processing terminal device 10.
 使用者は、たとえば、情報処理端末装置10を操作してウェブブラウザを立ち上げ、このウェブブラウザ上での操作によって、信号表示灯1,100に対する各種設定を行うことができる。 The user can, for example, operate the information processing terminal device 10 to start up a web browser, and perform various settings for the signal indicator lamps 1 and 100 by operations on the web browser.
 信号表示灯1は、入力信号線8の入力に従って表示動作を実行する。ミラーリング動作を設定するときには、管理用信号表示灯100において表示状態が模擬される被模擬側(ミラーリング元)の信号表示灯1(たとえば、全ての信号表示灯1A~1C)は、入力信号を表す入力情報および/または表示状態を表す表示状態情報を管理用信号表示灯100に送信する。 The signal indicator lamp 1 performs a display operation according to the input of the input signal line 8. When setting the mirroring operation, the signal indicator lamp 1 (for example, all signal indicator lamps 1A to 1C) on the simulated side (mirroring source) whose display state is simulated in the management signal indicator lamp 100 represents an input signal. The input information and / or display state information indicating the display state is transmitted to the management signal indicator lamp 100.
 より具体的には、信号表示灯1では、CPU50は、入力信号線8から入力回路53に入力される入力信号(制御信号)に応答し、その入力信号に対応する表示制御情報を不揮発性メモリ55から読み出す。CPU50は、その表示制御情報に対応する表示制御信号を表示部駆動ユニット51に与える。それにより、表示部12は、入力信号線8から入力される入力信号に応じた表示状態(発光状態)となる。一方、当該信号表示灯1をミラーリング元とするミラーリング動作が設定される場合には、CPU50は、表示部12の表示状態を表す表示状態情報を、管理用信号表示灯100を送信先として、ネットワークインタフェース17から送信させる。送信先の宛先情報(たとえばIPアドレス)は、情報処理端末装置10によって予め設定される。すなわち、送信先の宛先情報は、ミラーリング先の信号表示灯100の宛先情報である。 More specifically, in the signal indicator lamp 1, the CPU 50 responds to an input signal (control signal) input from the input signal line 8 to the input circuit 53, and displays display control information corresponding to the input signal in the nonvolatile memory. Read from 55. The CPU 50 gives a display control signal corresponding to the display control information to the display unit drive unit 51. Thereby, the display unit 12 enters a display state (light emission state) according to the input signal input from the input signal line 8. On the other hand, when the mirroring operation using the signal indicator lamp 1 as a mirroring source is set, the CPU 50 displays the display state information indicating the display state of the display unit 12 with the management signal indicator lamp 100 as a transmission destination. It is transmitted from the interface 17. The destination information (for example, IP address) of the transmission destination is set in advance by the information processing terminal device 10. That is, the destination information of the transmission destination is the destination information of the signal indicator lamp 100 of the mirroring destination.
 表示制御情報は、入力信号線8からの入力信号を入力とし、その入力に対する表示部12の表示状態を対応付けた制御情報である。したがって、信号表示灯1から管理用信号表示灯100に送信される表示状態情報は、表示制御情報であってもよい。また、入力信号と表示状態とは対応しているので、入力信号を表す入力情報を表示状態情報として取り扱うこととして、入力情報を信号表示灯1から管理用信号表示灯100に送信してもよい。 The display control information is control information in which an input signal from the input signal line 8 is input and the display state of the display unit 12 corresponding to the input is associated. Therefore, the display state information transmitted from the signal indicator lamp 1 to the management signal indicator lamp 100 may be display control information. Further, since the input signal corresponds to the display state, the input information may be transmitted from the signal display lamp 1 to the management signal display lamp 100 as handling the input information representing the input signal as the display state information. .
 管理用信号表示灯100では、ネットワークインタフェース17を介して取得される表示状態情報を表示部12の表示状態に反映させる動作を実行する。具体的には、CPU50は、ネットワークインタフェース17から表示状態情報が取得されると、その表示状態情報に対応する管理表示制御情報を生成し、その管理表示制御情報に対応する表示制御信号を表示部駆動ユニット51に与える。それにより、表示部12は、ネットワーク3から与えられた表示状態情報に基づいた表示状態(発光状態)となる。 The management signal indicator lamp 100 executes an operation of reflecting the display state information acquired via the network interface 17 in the display state of the display unit 12. Specifically, when the display state information is acquired from the network interface 17, the CPU 50 generates management display control information corresponding to the display state information, and displays a display control signal corresponding to the management display control information on the display unit. This is given to the drive unit 51. Thereby, the display unit 12 enters a display state (light emission state) based on the display state information given from the network 3.
 使用者は、予め、各信号表示灯1に表示制御情報を設定し、管理用信号表示灯100に管理表示制御情報を設定する。すなわち、各信号表示灯1の不揮発性メモリ55に表示制御情報が格納され、管理用信号表示灯100の不揮発性メモリ55に管理表示制御情報が格納される。生産装置A~Cに接続された一部または全部の信号表示灯1に共通の表示制御情報が設定されてもよいし、各信号表示灯1に個別の表示制御情報が設定されてもよい。
表示制御情報の設定は、情報処理端末装置10からネットワーク3を介して、各信号表示灯1に表示制御情報を送信し、各信号表示灯1のCPU50が当該表示制御情報を受け付けて不揮発性メモリ55に書き込むことによって達成できる。同様に、管理表示制御情報の設定は、情報処理端末装置10からネットワーク3を介して、管理用信号表示灯100に管理表示制御情報を送信し、管理用信号表示灯100のCPU50が当該管理表示制御情報を受け付けて不揮発性メモリ55に書き込むことによって達成できる。また、このような処理の代わりに、各信号表示灯1,100に対して、ネットワーク3を介することなく、予め表示制御情報または管理表示制御情報を設定しておいてもよい。たとえば、信号表示灯1,100に外部接続インタフェースを設けておき、この外部接続インタフェースを利用して表示制御情報または管理表示制御情報が設定されてもよい。外部接続インタフェースは、USBインタフェースであってもよい。たとえば、表示制御情報または管理表示制御情報を格納したUSBメモリをUSBインタフェースに接続することによって、CPU50の働きにより、USBメモリから表示制御情報または管理表示制御情報が読み出され、その表示制御情報または管理表示制御情報が不揮発性メモリ55に書き込まれてもよい。
The user sets display control information for each signal indicator lamp 1 in advance and sets management display control information for the management signal indicator lamp 100. That is, display control information is stored in the nonvolatile memory 55 of each signal indicator lamp 1, and management display control information is stored in the nonvolatile memory 55 of the management signal indicator lamp 100. Display control information common to some or all of the signal indicators 1 connected to the production apparatuses A to C may be set, or individual display control information may be set for each signal indicator 1.
The display control information is set by transmitting the display control information from the information processing terminal device 10 to each signal indicator lamp 1 via the network 3, and the CPU 50 of each signal indicator lamp 1 receives the display control information and receives a non-volatile memory. This can be accomplished by writing to 55. Similarly, the management display control information is set by transmitting the management display control information from the information processing terminal device 10 to the management signal indicator lamp 100 via the network 3, and the CPU 50 of the management signal indicator lamp 100 performs the management display. This can be achieved by receiving control information and writing it to the nonvolatile memory 55. Instead of such processing, display control information or management display control information may be set in advance for each of the signal indicator lamps 1 and 100 without using the network 3. For example, the signal display lamps 1 and 100 may be provided with an external connection interface, and display control information or management display control information may be set using the external connection interface. The external connection interface may be a USB interface. For example, by connecting a USB memory storing display control information or management display control information to the USB interface, the display control information or management display control information is read from the USB memory by the operation of the CPU 50, and the display control information or Management display control information may be written in the nonvolatile memory 55.
 たとえば、各表示ユニット20が、フルカラー表示が可能なフルカラー表示ユニットである場合には、表示制御情報および/または管理表示制御情報は、フルカラー表示のためのカラーデータを含んでもよい。カラーデータは、具体的には、複数階調の三原色データを含んでもよい。より具体的には、表示制御情報および管理表示制御情報は、16階調の赤色データ、16階調の緑色データ、16階調の青色データを含んでいてもよい。むろん、階調数は一例であり、各色の輝度を256階調で表す三原色データが用いられてもよい。 For example, when each display unit 20 is a full color display unit capable of full color display, the display control information and / or management display control information may include color data for full color display. Specifically, the color data may include three primary color data of a plurality of gradations. More specifically, the display control information and the management display control information may include 16 gradation red data, 16 gradation green data, and 16 gradation blue data. Of course, the number of gradations is an example, and three primary color data representing the luminance of each color in 256 gradations may be used.
 図4は、表示状態情報の一例を示す。ここでは、表示制御情報と同じデータ形式の表示状態情報の例を示す。この例の表示状態情報は、表示部12の各段の表示ユニット20の点灯色を表す情報である。より具体的には、この例の表示状態情報は、第1段~第N段(Nは信号表示灯1が有する表示ユニット20の数)の表示ユニット20について、三原色輝度データを含む。三原色輝度データは、赤色輝度データ(R)、緑色輝度データ(G)および青色輝度データ(G)を含む。すなわち、表示状態情報は、各段の表示ユニット20を識別するためのユニット識別情報と、各色の輝度データR,G,Bとの組で表現されている。各色の輝度データR,G,Bは、この例では、0~15の16階調で各色の輝度を表している。 FIG. 4 shows an example of display state information. Here, an example of display state information in the same data format as the display control information is shown. The display state information in this example is information representing the lighting color of the display unit 20 in each stage of the display unit 12. More specifically, the display state information in this example includes three primary color luminance data for the display units 20 in the first to Nth stages (N is the number of display units 20 included in the signal indicator lamp 1). The three primary color luminance data includes red luminance data (R), green luminance data (G), and blue luminance data (G). That is, the display state information is expressed as a set of unit identification information for identifying the display unit 20 at each stage and the luminance data R, G, B of each color. In this example, the brightness data R, G, B of each color represents the brightness of each color with 16 gradations of 0 to 15.
 表示ユニット20がフルカラー表示ユニットでなく、より表示色が限定されたマルチカラーユニットである場合には、表示状態情報の情報量はより少なくなる。たとえば、表示ユニット20の光源30が、赤色発光ダイオード、青色発光ダイオードおよび緑色発光ダイオードを有していて、それらを個別にオン/オフすることによって複数色(消灯状態を含めて8色)の表示を実現する構成であってもよい。この場合には、赤色データ(R)、緑色データ(G)および青色データ(B)は、それぞれの色の発光ダイオードのオン/オフを表す各1ビットのデータ(合計3ビット)で各段の表示ユニット20の表示状態を表現できる。表示ユニット20の光源30が単色光源であり、そのオン/オフのみが行われる場合には、各段の表示ユニット20の表示状態情報は1ビットのデータとなる。 When the display unit 20 is not a full-color display unit but a multi-color unit with a more limited display color, the amount of display state information is smaller. For example, the light source 30 of the display unit 20 includes a red light emitting diode, a blue light emitting diode, and a green light emitting diode, and a plurality of colors (eight colors including a light-off state) are displayed by individually turning them on / off. The structure which implement | achieves may be sufficient. In this case, the red data (R), the green data (G), and the blue data (B) are 1-bit data (3 bits in total) representing the on / off state of the light emitting diodes of the respective colors. The display state of the display unit 20 can be expressed. When the light source 30 of the display unit 20 is a monochromatic light source and only the on / off thereof is performed, the display state information of the display unit 20 at each stage is 1-bit data.
 図5は、管理表示制御情報(表示状態決定テーブル)の一例を示す。この例は、2つの信号表示灯1A,1Bの表示状態を管理用信号表示灯100で集約表現して表示する場合の管理表示制御情報を示す。 FIG. 5 shows an example of management display control information (display state determination table). This example shows management display control information when the display state of the two signal indicator lamps 1A and 1B is collectively displayed by the management signal indicator lamp 100.
 信号表示灯1から管理用信号表示灯100に送信される表示状態情報は、たとえば、信号表示灯識別情報と、ユニット識別情報と、発光状態データとを含む。信号表示灯識別情報は、信号表示灯1の識別情報であり、たとえば、信号表示灯1に付与されたIPアドレスである。ユニット識別情報は、当該信号表示灯1に備えられた表示ユニット20を識別するための情報、すなわち、当該信号表示灯1の何段目の表示ユニット20であるかを表す情報である。そして、発光状態データは、当該表示ユニットの光源30の発光色を表すデータ、たとえば、前述のような三原色輝度データである。 Display state information transmitted from the signal indicator lamp 1 to the management signal indicator lamp 100 includes, for example, signal indicator identification information, unit identification information, and light emission state data. The signal indicator identification information is identification information of the signal indicator 1, and is, for example, an IP address assigned to the signal indicator 1. The unit identification information is information for identifying the display unit 20 provided in the signal indicator lamp 1, that is, information indicating which level of the display unit 20 of the signal indicator lamp 1 is. The light emission state data is data representing the light emission color of the light source 30 of the display unit, for example, the three primary color luminance data as described above.
 図5では、信号表示灯1AのIPアドレスを「IPアドレス1」と表し、信号表示灯1BのIPアドレスを「IPアドレス2」と表してある。また、たとえば、信号表示灯1A,1Bは、入力信号に応じて、第1段の表示ユニット21が緑色点灯または消灯され、第2段の表示ユニット22が黄色点灯または消灯され、第3段の表示ユニット23が赤色点灯または消灯されるように、表示制御情報が設定されているものとする。そして、第1段、第2段および第3段の表示ユニット21,22,23は、いずれか一つが点灯状態に制御されるとき、他は消灯状態に制御されるものとする。一方、管理用信号表示灯100は、第1段の表示ユニット21が消灯および緑色点灯のいずれかの状態をとり、第2段の表示ユニット22が消灯、黄色点滅および黄色点灯のいずれかの状態をとり、第3段の表示ユニット23が消灯、赤色点滅および赤色点灯のいずれかの状態をとるように、管理表示制御情報が設定されているものとする。そして、第1段、第2段および第3段の表示ユニット21,22,23は、いずれか一つが点灯または点滅するとき、他は消灯状態に制御されるものとする。 In FIG. 5, the IP address of the signal indicator lamp 1A is represented as “IP address 1”, and the IP address of the signal indicator lamp 1B is represented as “IP address 2”. Further, for example, in the signal indicator lamps 1A and 1B, according to the input signal, the first stage display unit 21 is turned on or off in green, the second stage display unit 22 is turned on or off in yellow, and the third stage display unit 22 is turned on. It is assumed that the display control information is set so that the display unit 23 is turned on or off in red. The first-stage, second-stage, and third- stage display units 21, 22, and 23 are controlled to be turned off when any one is controlled to be turned on. On the other hand, in the management signal indicator lamp 100, the first-stage display unit 21 is either off or lit in green, and the second-stage display unit 22 is off, lit yellow, or lit yellow. It is assumed that the management display control information is set so that the display unit 23 in the third stage is in the off state, blinking in red, or lit in red. The display units 21, 22, and 23 in the first, second, and third stages are controlled to be turned off when any one of them is turned on or blinking.
 図5に示す管理表示制御情報は、具体的には、次のように管理用信号表示灯100の表示部12を制御させる情報である。 Specifically, the management display control information shown in FIG. 5 is information for controlling the display unit 12 of the management signal indicator lamp 100 as follows.
 信号表示灯1A,1Bの第1段の表示ユニット21がいずれも緑色で点灯しているとき、管理用信号表示灯100の第1段の表示ユニット21が緑色点灯(または消灯)する。 When the first stage display units 21 of the signal indicator lamps 1A and 1B are both lit in green, the first stage display unit 21 of the management signal indicator lamp 100 is lit in green (or turned off).
 信号表示灯1A,1Bの一方において第1段の表示ユニット21が緑色で点灯し、かつそれらの他方において第2段の表示ユニット22が黄色で点灯しているとき、管理用信号表示灯100の第2段の表示ユニット22が黄色で点滅する。 When the first-stage display unit 21 is lit in green on one of the signal indicators 1A and 1B, and the second-stage display unit 22 is lit in yellow on the other of the signal indicators 1A and 1B, The second display unit 22 blinks yellow.
 信号表示灯1A,1Bの一方において第1段の表示ユニット21が緑色で点灯し、かつそれらの他方において第3段の表示ユニットが赤色で点灯しているとき、管理用信号表示灯100の第2段の表示ユニット22が黄色で点灯(連続点灯)する。 When the first-stage display unit 21 is lit in green on one of the signal indicators 1A and 1B and the third-stage display unit is lit in red on the other of the signal indicators 1A and 1B, The two-stage display unit 22 lights in yellow (continuous lighting).
 信号表示灯1A,1Bの両方において第2段の表示ユニット22が黄色で点灯しているとき、管理用信号表示灯100の第3段の表示ユニット23が赤色で点滅する。 When the second stage display unit 22 is lit in yellow in both the signal indicator lamps 1A and 1B, the third stage display unit 23 of the management signal indicator lamp 100 blinks in red.
 信号表示灯1A,1Bの一方において第2段の表示ユニット22が黄色で点灯し、他方において第3段の表示ユニット23が赤色で点灯しているとき、管理用信号表示灯100の第3段の表示ユニット23が赤色で点灯(連続点灯)する。 When the second stage display unit 22 is lit in yellow on one of the signal indicator lamps 1A and 1B and the third stage display unit 23 is lit in red on the other side, the third stage of the management signal indicator lamp 100 is illuminated. The display unit 23 is lit in red (continuous lighting).
 信号表示灯1A,1Bの両方において、第3段の表示ユニット23が赤色で点灯しているとき、管理用信号表示灯100の第3段の表示ユニット23が赤色で点灯(連続点灯)する。 In both the signal indicator lamps 1A and 1B, when the third stage display unit 23 is lit in red, the third stage display unit 23 of the management signal indicator lamp 100 is lit in red (continuous lighting).
 このように、管理用信号表示灯100は、信号表示灯1A,1Bの表示状態の組み合わせによって規定される表示状態となり、信号表示灯1A,1Bの表示状態を集約した表示状態に制御される。したがって、管理用信号表示灯100の表示状態は、生産装置A,Bの状態を全体的に表すことになる。したがって、管理者は、管理用信号表示灯100を視認することによって、生産装置A,Bの全体の稼働状況を知ることができる。 Thus, the management signal indicator lamp 100 is in a display state defined by a combination of display states of the signal indicator lamps 1A and 1B, and is controlled to a display state in which the display states of the signal indicator lamps 1A and 1B are integrated. Therefore, the display state of the management signal indicator lamp 100 generally represents the state of the production apparatuses A and B. Therefore, the manager can know the overall operating status of the production apparatuses A and B by visually recognizing the management signal indicator lamp 100.
 もちろん、信号表示灯1A,1B,1Cの表示状態に基づいて、図5のテーブル(表示状態決定テーブル)に類似した、いわば三次元テーブル(表示状態決定テーブル)によって管理表示制御情報を規定することもできる。それにより、管理用信号表示灯100は、3つの生産装置A,B,Cの全体的な稼働状況を表す表示状態となる。 Of course, the management display control information is defined by a so-called three-dimensional table (display state determination table) similar to the table of FIG. 5 (display state determination table) based on the display states of the signal indicators 1A, 1B, and 1C. You can also. As a result, the management signal indicator lamp 100 enters a display state that represents the overall operating status of the three production apparatuses A, B, and C.
 図6は、信号表示灯1(ミラーリング元)の動作例を説明するためのフローチャートである。この動作は、所定の制御周期で繰り返し実行される。CPU50は、入力回路53に入力される入力信号を参照して、入力信号が変化したかどうかを判断する(ステップS1)。入力信号に変化がなければ、今制御周期での処理を終える。入力信号に変化があれば(ステップS1:YES)、CPU50は、入力信号に対応する表示制御情報を不揮発性メモリ55から読み出す(ステップS2)。この表示制御情報に対応する表示制御信号が、表示部駆動ユニット51に与えられる。こうして、表示部12は、入力信号に対応した表示状態となる(ステップS3)。入力信号に変化がなければ、従前の表示状態が維持される。さらに、CPU50は、自身の信号表示灯1の表示部12の表示状態を表す表示状態情報(たとえば前記表示制御情報)を管理用信号表示灯100のIPアドレスを宛先として送出して(ステップS4)、今制御周期の処理を終える。 FIG. 6 is a flowchart for explaining an operation example of the signal indicator lamp 1 (mirroring source). This operation is repeatedly executed at a predetermined control cycle. The CPU 50 refers to the input signal input to the input circuit 53 and determines whether or not the input signal has changed (step S1). If there is no change in the input signal, the process in the control cycle is finished. If there is a change in the input signal (step S1: YES), the CPU 50 reads display control information corresponding to the input signal from the nonvolatile memory 55 (step S2). A display control signal corresponding to the display control information is given to the display unit drive unit 51. Thus, the display unit 12 enters a display state corresponding to the input signal (step S3). If there is no change in the input signal, the previous display state is maintained. Further, the CPU 50 sends out display state information (for example, the display control information) indicating the display state of the display unit 12 of its own signal indicator lamp 1 with the IP address of the management signal indicator lamp 100 as a destination (step S4). Now, the processing of the control cycle is finished.
 図7は、管理用信号表示灯100(ミラーリング先)がミラーリング元の信号表示灯1からの表示状態情報を受信する処理の例を説明するためのフローチャートである。管理用信号表示灯100では、この処理が制御周期毎に繰り返し実行される。CPU50は、ミラーリング元(信号表示灯1)からの接続要求を待機し(ステップS21)、接続要求がなければ(ステップS21:NO)、処理を終了する。接続要求があると(ステップS21:YES)、CPU50は、ネットワークインタフェース17を介して、受信確認を送出して、接続を確立させる(ステップS22)。その後、CPU50は、表示状態情報を受信すると(ステップS23:YES)、その受信した表示状態情報をメモリ54(RAM56)に格納する(ステップS24)。その後は、ステップS23に戻る。一方、表示状態情報が受信されなければ(ステップS23:NO)、CPU50は、ミラーリング元との接続が切断されたかどうかを調べる(ステップS25)。接続が切断されると(ステップS25:YES)、処理を終える。接続が切断されていなければ、ステップS23に戻って、表示状態情報の受信を待機する。 FIG. 7 is a flowchart for explaining an example of processing in which the management signal indicator lamp 100 (mirroring destination) receives the display state information from the mirroring source signal indicator lamp 1. In the management signal indicator lamp 100, this process is repeatedly executed every control cycle. The CPU 50 waits for a connection request from the mirroring source (signal indicator lamp 1) (step S21). If there is no connection request (step S21: NO), the process is terminated. When there is a connection request (step S21: YES), the CPU 50 sends a reception confirmation via the network interface 17 to establish a connection (step S22). Thereafter, when receiving the display state information (step S23: YES), the CPU 50 stores the received display state information in the memory 54 (RAM 56) (step S24). Thereafter, the process returns to step S23. On the other hand, if the display state information is not received (step S23: NO), the CPU 50 checks whether or not the connection with the mirroring source is disconnected (step S25). When the connection is disconnected (step S25: YES), the process is finished. If the connection has not been disconnected, the process returns to step S23 to wait for display state information to be received.
 図8は、管理用信号表示灯100(ミラーリング先)の表示制御に関する動作例を説明するためのフローチャートである。管理用信号表示灯100では、この処理が制御周期毎に繰り返し実行される。CPU50は、ミラーリング元(信号表示灯1)との接続が確立されているかどうかを判断し(ステップS31)、接続が確立されていなければ(ステップS31:NO)、表示部駆動ユニット51に対して、全ての表示ユニット20を消灯状態とするための表示制御信号を与えて(ステップS32)、今制御周期の処理を終える。 FIG. 8 is a flowchart for explaining an operation example related to display control of the management signal indicator lamp 100 (mirroring destination). In the management signal indicator lamp 100, this process is repeatedly executed every control cycle. The CPU 50 determines whether or not the connection with the mirroring source (signal indicator lamp 1) has been established (step S31). If the connection has not been established (step S31: NO), the display unit drive unit 51 is checked. Then, a display control signal for turning off all the display units 20 is given (step S32), and the processing of the current control cycle is finished.
 一方、ミラーリング元(信号表示灯1)との接続が確立されている場合には(ステップS31:YES)、CPU50は、メモリ54(RAM56)に格納された表示状態情報を参照し、表示状態情報に変化があったかどうかを判断する(ステップS33)。表示状態情報に変化がなければ(ステップS33:NO)、今制御周期での処理を終了する。表示状態情報に変化があれば(ステップS33:YES)、CPU50は、変化後の表示状態情報に基づいて、不揮発性メモリ55に格納された管理表示制御情報を読み出す(ステップS34)。CPU50は、その読み出した管理表示制御情報に対応する表示制御信号を表示部駆動ユニット51に与える(ステップS35)。それにより、表示部12は、変化後の表示状態情報に対応した表示状態となる。この表示状態は、前述のとおり、複数の信号表示灯1の表示状態を集約した表示状態である。 On the other hand, when the connection with the mirroring source (signal indicator lamp 1) is established (step S31: YES), the CPU 50 refers to the display state information stored in the memory 54 (RAM 56) and displays the display state information. It is determined whether or not there has been a change (step S33). If there is no change in the display state information (step S33: NO), the process in the current control cycle is terminated. If there is a change in the display state information (step S33: YES), the CPU 50 reads the management display control information stored in the nonvolatile memory 55 based on the display state information after the change (step S34). CPU50 gives the display control signal corresponding to the read management display control information to the display part drive unit 51 (step S35). Thereby, the display part 12 will be in the display state corresponding to the display state information after a change. As described above, this display state is a display state in which the display states of the plurality of signal indicator lamps 1 are collected.
 さらに、CPU50は、いずれの信号表示灯1のミラーリングを行っているのかを表す音声をスピーカ16から発生させ、ミラーリング元を報知する(ステップS36。模擬表示元報知手段)。たとえば、CPU50は、「信号表示灯***の状態を集約表示しています。」などといった音声メッセージを発音させるための発音制御信号をスピーカ駆動ユニット52に与えてもよい。ミラーリング元の信号表示灯1の報知は、表示部12の表示によって行われてもよい。 Furthermore, the CPU 50 generates a sound indicating which of the signal indicator lamps 1 is being mirrored from the speaker 16 and notifies the mirroring source (step S36, simulated display source notification means). For example, the CPU 50 may provide the speaker drive unit 52 with a sound generation control signal for generating a voice message such as “the state of the signal indicator lamp *** is collectively displayed”. The notification of the signal indicator lamp 1 of the mirroring source may be performed by displaying on the display unit 12.
 このようにこの実施形態によれば、複数の信号表示灯1の表示状態をネットワーク3を介して管理用信号表示灯100においてミラーリングすることができる。それにより、管理用信号表示灯100の近くにいる使用者(たとえば管理者)は、直接視認することができない遠くの信号表示灯1A~1Cによって提供されている情報を、管理用信号表示灯100の表示状態を目視することで確認できる。それにより、生産装置A~Cの近くまで移動することなく、生産装置A~Cの稼働状況を把握できる。しかも、管理用信号表示灯100は、信号表示灯としての基本構成を有しているから、或る程度遠くからでも点灯状態を目視できるように構成されており、しかも発光による報知の方向も管理用信号表示灯100の周囲の広い範囲に渡っている。したがって、使用者は、管理用信号表示灯100の周囲の広い範囲から管理用信号表示灯100を目視できるので、自由な位置にいることができ、場合によっては、別の作業に従事しながら管理用信号表示灯100の表示状態を確認することも可能である。これにより、利便性に優れた信号表示灯システムを提供できる。 Thus, according to this embodiment, the display state of the plurality of signal indicator lamps 1 can be mirrored in the management signal indicator lamp 100 via the network 3. As a result, a user (for example, a manager) who is near the management signal display lamp 100 can use the management signal display lamp 100 to display information provided by the remote signal display lamps 1A to 1C that cannot be directly visually recognized. It can be confirmed by visually checking the display state. Thereby, it is possible to grasp the operating status of the production apparatuses A to C without moving to the vicinity of the production apparatuses A to C. In addition, since the management signal indicator lamp 100 has a basic configuration as a signal indicator lamp, it is configured so that the lighting state can be seen from a certain distance, and the direction of notification by light emission is also managed. It extends over a wide area around the signal indicator lamp 100. Therefore, since the user can visually observe the management signal indicator lamp 100 from a wide range around the management signal indicator lamp 100, the user can be in a free position, and in some cases, while performing another work, the management can be performed. It is also possible to check the display state of the signal indicator lamp 100. Thereby, the signal indicator lamp system excellent in convenience can be provided.
 そして、この実施形態では、管理用信号表示灯100は、信号表示灯1の表示状態をそのままミラーリングするのではなく、信号表示灯1の表示状態情報に対応し、かつ信号表示灯1の表示状態とは異なる表示状態に制御される。それによって、管理用信号表示灯100は、使用者(たとえば管理者)が必要とする情報を適切に提供する。 In this embodiment, the management signal indicator lamp 100 does not mirror the display state of the signal indicator lamp 1 as it is, but corresponds to the display state information of the signal indicator lamp 1 and the display state of the signal indicator lamp 1. Is controlled to a different display state. Thereby, the management signal indicator lamp 100 appropriately provides information required by the user (for example, a manager).
 具体的には、図5を用いて説明したとおり、管理用信号表示灯100の表示状態は、複数の信号表示灯1の表示状態の組み合わせによって決定されてもよい。それにより、複数の生産装置A~Cの全体の稼働状況を管理用信号表示灯100によって報知することができる。 Specifically, as described with reference to FIG. 5, the display state of the management signal indicator lamp 100 may be determined by a combination of the display states of the plurality of signal indicator lamps 1. As a result, the overall operating status of the plurality of production apparatuses A to C can be notified by the management signal indicator lamp 100.
 なお、前述の説明では、信号表示灯1が入力信号の変化に応答して自発的に表示状態情報を管理用信号表示灯100に送信することとしているが(図6参照)、これは通信処理の一例である。すなわち、信号表示灯1は、入力信号の変化の有無によらずに、定期的に表示状態情報を管理用信号表示灯100に送信してもよい。また、信号表示灯1が自発的に表示状態情報を送信するのではなく、管理用信号表示灯100からの要求によって、管理用信号表示灯100が各信号表示灯1から表示状態情報を取得する通信方式であってもよい。この場合、たとえば、管理用信号表示灯100は、定期的に各信号表示灯1に対して表示状態情報取得要求を送信する。それに応答して、各信号表示灯1は、管理用信号表示灯100に対して、表示状態情報を送信する。 In the above description, the signal indicator lamp 1 voluntarily transmits display state information to the management signal indicator lamp 100 in response to a change in the input signal (see FIG. 6). This is a communication process. It is an example. That is, the signal indicator lamp 1 may periodically transmit the display state information to the management signal indicator lamp 100 regardless of whether or not the input signal has changed. The signal indicator lamp 1 does not spontaneously transmit the display state information, but the management signal indicator lamp 100 acquires the display state information from each signal indicator lamp 1 in response to a request from the management signal indicator lamp 100. A communication method may be used. In this case, for example, the management signal indicator lamp 100 periodically transmits a display state information acquisition request to each signal indicator lamp 1. In response thereto, each signal indicator lamp 1 transmits display state information to the management signal indicator lamp 100.
 図9は、この発明の第2の実施形態を説明するための図であり、信号表示灯1A,1B,1Cの表示状態に基づいて管理用信号表示灯100の表示状態を決定するための表示状態決定テーブルを示す。 FIG. 9 is a diagram for explaining a second embodiment of the present invention, and a display for determining the display state of the management signal indicator lamp 100 based on the display states of the signal indicator lamps 1A, 1B, 1C. A state determination table is shown.
 この例では、信号表示灯1A,1B,1Cは、それぞれ、「エラー1」、「エラー2」および「正常」の3つの表示状態のいずれかに制御される。「エラー1」は、第1段階の異常発生時、すなわち、軽微な異常発生時の表示状態であり、たとえば、第2段の表示ユニット22を黄色で点灯させる状態であってもよい。「エラー2」は、第2段階の異常発生時、すなわち、重度の異常発生時の表示状態であり、たとえば、第3段の表示ユニット23を赤色で点灯させる状態であってもよい。「正常」は、正常時の表示状態であり、たとえば、第1段の表示ユニット21を緑色で点灯させる状態であってもよい。 In this example, the signal indicators 1A, 1B, and 1C are controlled to one of three display states of “error 1”, “error 2”, and “normal”, respectively. “Error 1” is a display state when a first stage abnormality occurs, that is, a minor abnormality, for example, and may be a state where the second-stage display unit 22 is lit in yellow. “Error 2” is a display state when a second stage abnormality occurs, that is, a severe abnormality occurs. For example, the third stage display unit 23 may be lit in red. “Normal” is a normal display state, and may be, for example, a state in which the first-stage display unit 21 is lit in green.
 一方、管理用信号表示灯100は、「エラー」、「注意」および「正常」の3つの表示状態のいずれかに制御される。「エラー」は、異常発生を報知する表示状態であり、たとえば、第3段の表示ユニット23を赤色で点灯させる状態であってもよい。「注意」は、軽微な異常発生を報知する表示状態であり、たとえば、第2段の表示ユニット22を黄色で点灯させる状態であってもよい。「正常」は、正常であることを報知する表示状態であり、たとえば、第1段の表示ユニット21を緑色で点灯させる状態であってもよい。 On the other hand, the management signal indicator lamp 100 is controlled to one of three display states of “error”, “caution”, and “normal”. “Error” is a display state for notifying the occurrence of an abnormality, and may be a state in which the third-stage display unit 23 is lit in red, for example. “Caution” is a display state for notifying the occurrence of a minor abnormality. For example, the second stage display unit 22 may be lit in yellow. “Normal” is a display state informing that it is normal, and may be a state in which the first-stage display unit 21 is lit in green, for example.
 図9の表示状態決定テーブルでは、信号表示灯1A,1B,1Cの表示状態がいずれも「正常」である場合、管理用信号表示灯100の表示状態は、「正常」に設定される。また、信号表示灯1A,1B,1Cのうちの一つ以上の表示状態が「エラー1」であっても、いずれの信号表示灯1A,1B,1Cの表示状態も「エラー2」でなければ、管理用信号表示灯100の表示状態は、「正常」に設定される。すなわち、信号表示灯1A,1B,1Cの表示状態に「エラー1」と「正常」とが混在している場合、および全ての信号表示灯1A,1B,1Cの表示状態が「エラー1」である場合であっても、管理用信号表示灯100の表示状態は「正常」となる。そして、信号表示灯1A,1B,1Cのうちの一つまたは2つの表示状態が「エラー2」である場合には、管理用信号表示灯100の表示状態は「注意」に設定される。信号表示灯1A,1B,1Cの全ての表示状態が「エラー2」であるときは、管理用信号表示灯100の表示状態は「エラー」に設定される。 In the display state determination table of FIG. 9, when the display states of the signal indicator lamps 1A, 1B, and 1C are all “normal”, the display state of the management signal indicator lamp 100 is set to “normal”. Further, even if one or more of the signal display lamps 1A, 1B, 1C is “error 1”, the display status of any of the signal display lamps 1A, 1B, 1C is not “error 2”. The display state of the management signal indicator lamp 100 is set to “normal”. That is, when “error 1” and “normal” are mixed in the display states of the signal indicators 1A, 1B, and 1C, and the display states of all the signal indicators 1A, 1B, and 1C are “error 1”. Even in some cases, the display state of the management signal indicator lamp 100 is “normal”. When the display state of one or two of the signal indicator lamps 1A, 1B, and 1C is “error 2”, the display state of the management signal indicator lamp 100 is set to “caution”. When all the display states of the signal indicator lamps 1A, 1B, and 1C are “error 2”, the display state of the management signal indicator lamp 100 is set to “error”.
 このように、この実施形態では、軽微なエラー(エラー1)については、各信号表示灯1では表示されるものの、管理用信号表示灯100では報知されない。たとえば、軽微なエラーは、生産装置A~Cの現場担当者に対して報知すれば足り、管理者への通知を要しない場合もある。具体的には、現場担当者の判断で解決できる事項であれば、管理者を巻き込む必要がない。このような場合に、軽微なエラーを管理用信号表示灯100で表示すると、不必要に管理者を巻き込み、業務効率が低下するおそれがある。 Thus, in this embodiment, a minor error (error 1) is displayed on each signal indicator 1 but is not notified on the management signal indicator 100. For example, a minor error may be notified to the person in charge of the production apparatuses A to C, and the manager may not be notified. Specifically, it is not necessary to involve an administrator as long as it can be resolved by the judgment of the person in charge at the site. In such a case, if a minor error is displayed on the management signal indicator lamp 100, an administrator may be involved unnecessarily, and business efficiency may be reduced.
 この実施形態の信号表示灯システムでは、個々の信号表示灯1の表示を確認することによって個々の生産装置A~Cの詳細な状態を把握できる一方で、管理用信号表示灯100は、複数の生産装置A~Cの全体的な稼働状態を報知する。それにより、たとえば工場内での人員配置を含む全体の業務管理の効率を向上できる。 In the signal indicator lamp system of this embodiment, the detailed state of each of the production apparatuses A to C can be grasped by confirming the display of each individual signal indicator lamp 1, while the management signal indicator lamp 100 includes a plurality of Notifies the overall operating status of the production apparatuses A to C. Thereby, for example, the efficiency of overall business management including personnel assignment in the factory can be improved.
 また、生産装置A~Cを含む生産設備(たとえば生産ライン)が全体としては稼働しており、一つの生産装置のみが停止しているような状況では、その対処を現場担当者に委ね、管理者への通知を省くことができる。それにより、生産工程全体の管理に対する負荷を軽減できる。その一方で、生産設備全体が停止したり、または停止する恐れがあったりする状況では、管理用信号表示灯100によって、管理者に対する報知を適切に行える。それにより、管理者による対処が必要な事象に関する情報、すなわち優先度の高い情報については、管理者への通知が行われ、管理者に対して対処を促すことができる。 Also, in the situation where the production equipment (for example, production line) including the production equipment A to C is operating as a whole and only one production equipment is stopped, the management is entrusted to the person in charge on the site. Notification to the person can be omitted. Thereby, it is possible to reduce the burden on the management of the entire production process. On the other hand, in a situation where the entire production facility is stopped or may be stopped, the management signal indicator lamp 100 can appropriately notify the administrator. As a result, the administrator is notified of information related to an event that needs to be dealt with by the administrator, that is, information with high priority, and the administrator can be encouraged to deal with it.
 なお、前述の説明では、異常の段階数が2である例を示したが、むろん、異常の段階数は3段階異常であってもよい。 In the above description, the example in which the number of abnormal stages is two has been shown, but the number of abnormal stages may be three-stage abnormal.
 図10は、この発明の第3の実施形態に係る信号表示灯システムを説明するための図であり、管理用信号表示灯100における表示状態決定処理を説明するためのフローチャートである。ミラーリング元となる信号表示灯1A,1B,1Cは、前述の第2の実施形態と同様に、「エラー1」、「エラー2」および「正常」の3つの表示状態のいずれかに制御される。また、管理用信号表示灯100も、前述の第2の実施形態と同様に、「エラー」、「注意」および「正常」の3つの表示状態のいずれかに制御される。 FIG. 10 is a diagram for explaining a signal indicator lamp system according to a third embodiment of the present invention, and is a flowchart for explaining a display state determination process in the management signal indicator lamp 100. The signal indicator lamps 1A, 1B, and 1C that are the mirroring sources are controlled to one of three display states of “error 1”, “error 2”, and “normal” as in the second embodiment. . The management signal indicator lamp 100 is also controlled to one of three display states of “error”, “caution”, and “normal”, as in the second embodiment.
 管理用信号表示灯100のCPU50は、信号表示灯1A,1B,1Cのそれぞれの表示情報状態に対してポイントを付与する(ステップS41)。たとえば、「正常」に対して0ポイント、「エラー1」に対して1ポイント、「エラー2」に対して2ポイントがそれぞれ付与される。管理用信号表示灯100のCPU50は、3つの信号表示灯1A,1B,1Cにそれぞれ付与されたポイントの合計を求める(ステップS42)。そして、CPU50は、その合計ポイントに基づいて、管理用信号表示灯100の表示状態を決定する(ステップS43)。たとえば、CPU50は、合計ポイントが1~3の場合は表示状態を「正常」と決定し、合計ポイントが4~5の場合は表示状態を「注意」と決定し、合意ポイントが6の場合は表示状態を「エラー」と決定してもよい。この決定は、合計ポイントと閾値との比較によって行ってもよいし、合計ポイントと表示状態とを対応付けたテーブルを用いて行ってもよい。 The CPU 50 of the management signal indicator lamp 100 gives points to the display information states of the signal indicator lamps 1A, 1B, and 1C (step S41). For example, 0 points are given to “normal”, 1 point is given to “error 1”, and 2 points are given to “error 2”. The CPU 50 of the management signal indicator lamp 100 calculates the total of points given to the three signal indicator lamps 1A, 1B, and 1C, respectively (step S42). Then, the CPU 50 determines the display state of the management signal indicator lamp 100 based on the total points (step S43). For example, when the total points are 1 to 3, the CPU 50 determines the display state as “normal”, when the total points is 4 to 5, the display state is determined as “attention”, and when the agreed point is 6, The display state may be determined as “error”. This determination may be performed by comparing the total points with a threshold value, or may be performed using a table in which the total points are associated with display states.
 このような構成でも、信号表示灯1A,1B,1Cの表示状態を集約して管理用信号表示灯100に表示できるので、管理者に対して、必要な情報を適切に伝達できる。 Even in such a configuration, since the display states of the signal indicator lamps 1A, 1B, and 1C can be aggregated and displayed on the management signal indicator lamp 100, necessary information can be appropriately transmitted to the administrator.
 図11は、この発明の第4の実施形態に係る信号表示灯システムを説明するための図であり、管理用信号表示灯100における表示状態の決定に関する処理(CPU50が制御周期毎に繰り返す処理)を示す。 FIG. 11 is a diagram for explaining a signal indicator lamp system according to a fourth embodiment of the present invention, and a process related to determination of a display state in the management signal indicator lamp 100 (a process that the CPU 50 repeats every control cycle). Indicates.
 この実施形態では、ミラーリング元の信号表示灯1は、タイムトリガモードまたはパルストリガモードに設定可能である。タイムトリガモードとは、表示部12の表示状態が時間経過に伴って変動し、それによって、経過時間表示を行う動作モードである。パルストリガモードとは、入力信号線8に所定の入力信号(パルス信号)が入力された回数に応じて表示部12の表示状態が変動し、それによって、積算量/積算数表示(進捗表示)を行う動作モードである。動作モードの設定は、情報処理端末装置10を用いて行うことができる。 In the present embodiment, the mirroring source signal indicator lamp 1 can be set to the time trigger mode or the pulse trigger mode. The time trigger mode is an operation mode in which the display state of the display unit 12 fluctuates with time, thereby displaying elapsed time. In the pulse trigger mode, the display state of the display unit 12 changes according to the number of times a predetermined input signal (pulse signal) is input to the input signal line 8, and accordingly, the integrated amount / integrated number display (progress display). Is an operation mode in which The operation mode can be set using the information processing terminal device 10.
 動作モードがタイムトリガモードに設定された信号表示灯1では、入力信号線8から入力される入力信号をトリガとしてタイマ58の計時が開始される。タイムトリガモードに対応して、不揮発性メモリ55には、複数の表示パターンを表す表示制御情報が格納される。入力信号線8に所定の入力信号が入力されると、CPU50は、最初の表示パターンを選択し、タイマ58をスタートさせる。タイマ58の計時時間が所定時間に達すると、それに応答して、CPU50は、別の一つの表示パターンを選択する。同様にして、CPU50は、複数の表示パターンのうちの一つを順次かつ循環的に選択し、その選択した表示パターンの表示制御情報に対応する表示制御信号を表示部駆動ユニット51に供給する。その結果、表示部12において、所定の入力信号の入力からの経過時間に応じて変動する表示を行える。それにより、表示部12は、経過時間表示を行うことができる。たとえば、表示部12の下から上(または上から下)に向かって発光領域が移動していくような移動表示、表示部12の下から上(または上から下)に向かって発光領域が延びていく(または縮んでいく)ような伸縮表示、表示部12の発光時間間隔が長く(または短く)なっていくような可変点滅間隔表示などが、経過時間表示の例である。 In the signal indicator lamp 1 in which the operation mode is set to the time trigger mode, the timer 58 starts timing with the input signal input from the input signal line 8 as a trigger. Corresponding to the time trigger mode, the nonvolatile memory 55 stores display control information representing a plurality of display patterns. When a predetermined input signal is input to the input signal line 8, the CPU 50 selects the first display pattern and starts the timer 58. When the time measured by the timer 58 reaches a predetermined time, in response thereto, the CPU 50 selects another display pattern. Similarly, the CPU 50 sequentially and cyclically selects one of the plurality of display patterns, and supplies a display control signal corresponding to the display control information of the selected display pattern to the display unit drive unit 51. As a result, the display unit 12 can perform a display that varies depending on the elapsed time from the input of the predetermined input signal. Thereby, the display part 12 can perform elapsed time display. For example, a moving display in which the light emitting region moves from the bottom to the top (or from top to bottom) of the display unit 12, or the light emitting region extends from the bottom to the top (or top to bottom) of the display unit 12. Examples of the elapsed time display include an expansion / contraction display that goes (or shrinks) and a variable blinking interval display that makes the light emission time interval of the display unit 12 longer (or shorter).
 動作モードがパルストリガモードに設定された信号表示灯1では、入力信号線8の一部が所定の入力信号(パルス信号)の入力のために割り当てられる。たとえば、それぞれオン/オフ信号が入力される4本の入力信号線8(入力1~4)が設けられている場合に、一つの入力4がパルス信号の入力に割り当てられ、残りの入力1~3がパルス信号以外の信号の入力に割り当てられてもよい。この場合、入力1~3に所定の入力信号が与えられるとCPU50の内部のカウンタがリセットされる。そして、入力4にパルス信号が入力されるたびに、当該カウンタがインクリメントされる。パルストリガモードに対応して、不揮発性メモリ55には、複数の表示パターンを表す表示制御情報が格納される。この表示制御情報は、タイムトリガモードと共通の情報であってもよいし、タイムトリガモードとは別の情報であってもよい。CPU50は、複数の表示パターンから、カウンタの値によって特定される一つの表示パターンを選択する。パルス信号が入力されるたびにカウンタがインクリメントされるので、パルス信号が繰り返し入力されることにより、CPU50は、複数の表示パターンのうちの一つを順次かつ循環的に選択し、その選択した表示パターンの表示制御情報に対応する表示制御信号を表示部駆動ユニット51に供給する。その結果、表示部12の表示状態(発光状態)は、カウンタの値に対応することになる。したがって、パルス信号の入力回数、すなわち積算量/積算数を表示することができ、たとえば生産装置における処理の進捗状態を表示できる。たとえば、表示部12の下から上(または上から下)に向かって発光領域が移動していくような移動表示、表示部12の下から上(または上から下)に向かって発光領域が延びていく(または縮んでいく)ような伸縮表示、表示部12の発光時間間隔が長く(または短く)なっていくような可変点滅間隔表示などが、積算量/積算数表示(進捗表示)の例である。 In the signal indicator lamp 1 whose operation mode is set to the pulse trigger mode, a part of the input signal line 8 is assigned for inputting a predetermined input signal (pulse signal). For example, in the case where four input signal lines 8 (inputs 1 to 4) for inputting ON / OFF signals are provided, one input 4 is assigned to the input of the pulse signal, and the remaining inputs 1 to 3 may be assigned to input of a signal other than the pulse signal. In this case, when a predetermined input signal is given to the inputs 1 to 3, the internal counter of the CPU 50 is reset. Each time a pulse signal is input to the input 4, the counter is incremented. Corresponding to the pulse trigger mode, the nonvolatile memory 55 stores display control information representing a plurality of display patterns. This display control information may be information common to the time trigger mode, or may be information different from the time trigger mode. The CPU 50 selects one display pattern specified by the counter value from the plurality of display patterns. Since the counter is incremented each time a pulse signal is input, the CPU 50 sequentially and cyclically selects one of a plurality of display patterns by repeatedly inputting the pulse signal, and the selected display A display control signal corresponding to the pattern display control information is supplied to the display unit drive unit 51. As a result, the display state (light emission state) of the display unit 12 corresponds to the counter value. Therefore, it is possible to display the number of pulse signals input, that is, the integrated amount / integrated number, and for example, display the progress of processing in the production apparatus. For example, a moving display in which the light emitting region moves from the bottom to the top (or from top to bottom) of the display unit 12, or the light emitting region extends from the bottom to the top (or top to bottom) of the display unit 12. Examples of integrated amount / integrated number display (progress display), such as expansion / contraction display that goes (or shrinks), variable flashing interval display that makes the light emission time interval of the display unit 12 longer (or shorter), etc. It is.
 このようなタイムトリガモードによる経過時間表示およびパルストリガモードによる積算量/積算数表示(進捗表示)についても、信号表示灯1A,1B,1Cにおける表示を集約して管理用信号表示灯100においてミラーリングできる。 Regarding the elapsed time display by the time trigger mode and the integrated amount / integrated number display (progress display) by the pulse trigger mode, the display on the signal display lamps 1A, 1B, and 1C is integrated and mirrored in the management signal display lamp 100. it can.
 たとえば、信号表示灯1A,1B,1Cは、それらが表示パターンの何番目を表示しているのかを表すパラメータp(パターン番号)を内部に保持している。このパラメータpは、表示部12の表示状態に対応する表示状態情報の一例である。管理用信号表示灯100のCPU50は、図11に示すように、それらのパラメータpを信号表示灯1A,1B,1Cから取得する(ステップS51)。そして、CPU50は、その取得されたパラメータpに対して、合計演算、平均値演算その他の適切な演算を実行し、管理用パラメータPを求める(ステップS52)。管理用信号表示灯100の不揮発性メモリ55には、タイムトリガモードおよびパルストリガモードに対応して、複数の表示パターンを表す管理表示制御情報が予め格納される。この管理表示制御情報は、タイムトリガモードおよびパルストリガモードに対応して個別に準備されてもよく、それらに共通の情報であってもよい。複数の表示パターンは、管理用パラメータPの複数の値にそれぞれ対応している。CPU50は、管理用パラメータPに基づいて表示パターンを特定し(ステップS53)、その表示パターンに対応した管理表示制御情報を不揮発性メモリ55から読み出す(ステップS54)。そして、CPU50は、その管理表示制御情報に対応した表示制御信号を表示部駆動ユニット51に供給する。それにより、管理用信号表示灯100の表示部12は、管理用パラメータPに対応した表示状態となる(ステップS55)。 For example, the signal indicator lamps 1A, 1B, and 1C internally hold a parameter p (pattern number) indicating what number of the display pattern they are displaying. The parameter p is an example of display state information corresponding to the display state of the display unit 12. As shown in FIG. 11, the CPU 50 of the management signal indicator lamp 100 acquires those parameters p from the signal indicator lamps 1A, 1B, 1C (step S51). Then, the CPU 50 performs a total calculation, an average value calculation and other appropriate calculations on the acquired parameter p to obtain a management parameter P (step S52). Management display control information representing a plurality of display patterns is stored in advance in the nonvolatile memory 55 of the management signal indicator lamp 100 in correspondence with the time trigger mode and the pulse trigger mode. This management display control information may be prepared individually corresponding to the time trigger mode and the pulse trigger mode, or may be information common to them. The plurality of display patterns correspond to the plurality of values of the management parameter P, respectively. The CPU 50 specifies a display pattern based on the management parameter P (step S53), and reads management display control information corresponding to the display pattern from the nonvolatile memory 55 (step S54). Then, the CPU 50 supplies a display control signal corresponding to the management display control information to the display unit drive unit 51. Thereby, the display unit 12 of the management signal indicator lamp 100 enters a display state corresponding to the management parameter P (step S55).
 このようにして、管理用信号表示灯100は、複数の信号表示灯1A,1B,1Cにおける時間経過表示または積算量/積算数表示(進捗表示)を集約した表示を使用者(とくに管理者)に提供できる。 In this way, the management signal indicator lamp 100 is a user (particularly an administrator) that displays a time-lapse display or integrated amount / integrated number display (progress display) in the plurality of signal indicator lamps 1A, 1B, 1C. Can be provided.
 図12は、この発明の第5の実施形態に係る信号表示灯システムの構成を説明するための概念図である。この実施形態では、ネットワーク3に接続された信号表示灯1A,1B,1Cは、それぞれ、液体タンク70A,70B,70C(以下、総称するときには「液体タンク70」という。)に貯留された液体71の液量および液温を表示するように構成されている。より具体的には、信号表示灯1A,1B,1Cには、それぞれ、センサユニット80A,80B,80C(以下、総称するときには「センサユニット80」という。)が信号変換ユニット75A,75B,75C(以下、総称するときには「信号変換ユニット75」という。)を介して接続されている。センサユニット80は、液面センサ81と、温度センサ82とを含む。液面センサ81は、液体タンク70内の液面の高さ(液量)を検出し、対応する検出信号を出力する。温度センサ82は、液体タンク70内の液体71の温度(液温)を検出し、対応する検出信号を出力する。すなわち、2つのセンサ81,82は、異なる種類の物理量をそれぞれ検出する。センサ81,82の出力信号は、信号変換ユニット75によってディジタルデータに変換され、信号表示灯1内の制御ユニット15に入力される。なお、信号変換ユニット75は、信号表示灯1の基台部11に組み込まれていてもよい。 FIG. 12 is a conceptual diagram for explaining a configuration of a signal indicator lamp system according to a fifth embodiment of the present invention. In this embodiment, the signal indicators 1A, 1B, and 1C connected to the network 3 are respectively the liquid 71 stored in the liquid tanks 70A, 70B, and 70C (hereinafter, collectively referred to as “liquid tank 70”). The liquid amount and the liquid temperature are displayed. More specifically, the signal indicator lamps 1A, 1B, and 1C include sensor units 80A, 80B, and 80C (hereinafter collectively referred to as “sensor unit 80”) as signal conversion units 75A, 75B, and 75C ( Hereinafter, they are collectively referred to as “signal conversion unit 75”. The sensor unit 80 includes a liquid level sensor 81 and a temperature sensor 82. The liquid level sensor 81 detects the height (liquid level) of the liquid level in the liquid tank 70 and outputs a corresponding detection signal. The temperature sensor 82 detects the temperature (liquid temperature) of the liquid 71 in the liquid tank 70 and outputs a corresponding detection signal. That is, the two sensors 81 and 82 detect different types of physical quantities, respectively. The output signals of the sensors 81 and 82 are converted into digital data by the signal conversion unit 75 and input to the control unit 15 in the signal indicator lamp 1. The signal conversion unit 75 may be incorporated in the base part 11 of the signal indicator lamp 1.
 信号表示灯1の不揮発性メモリ55には、二つの物量、すなわち、液量および液温を表示部12において表現するための表示制御情報が予め格納される。たとえば、点灯する表示ユニット20の数(すなわち、点灯領域の大きさ)によって液量が表現され、表示ユニット20の点灯色によって液温が表現されてもよい。この場合、たとえば、液量に応じて表示ユニット20を下段から順に点灯することとし、液量が多くなるほど点灯ユニット数が多くなるように表示制御情報が作成される。また、たとえば、液温に応じて寒色系から暖色系の色彩になるように表示制御情報が作成される。 In the non-volatile memory 55 of the signal indicator lamp 1, display control information for expressing two quantities, that is, the liquid amount and the liquid temperature on the display unit 12 is stored in advance. For example, the liquid amount may be expressed by the number of display units 20 to be lit (that is, the size of the lighting region), and the liquid temperature may be expressed by the lighting color of the display unit 20. In this case, for example, the display units 20 are sequentially lit from the bottom according to the liquid amount, and the display control information is created so that the number of lighting units increases as the liquid amount increases. In addition, for example, display control information is created so as to change from a cold color to a warm color according to the liquid temperature.
 したがって、信号表示灯1の表示部12は、液体タンク70内の液体71の液量に応じて点灯領域の大きさが変化し、その液温に応じて点灯色が変化するように制御される。このような表示部12の表示状態に対応する表示状態情報が、信号表示灯1A,1B,1Cからネットワーク3を介して管理用信号表示灯100に送信される。表示状態情報は、点灯している表示ユニット20の数(点灯領域の大きさ)に関する情報と、点灯色に関する情報とを含んでいてもよい。 Therefore, the display unit 12 of the signal indicator lamp 1 is controlled so that the size of the lighting region changes according to the amount of the liquid 71 in the liquid tank 70 and the lighting color changes according to the liquid temperature. . Display state information corresponding to the display state of the display unit 12 is transmitted from the signal indicator lamps 1A, 1B, and 1C to the management signal indicator lamp 100 via the network 3. The display state information may include information on the number of display units 20 that are lit (the size of the lighting area) and information on the lighting color.
 管理用信号表示灯100は、たとえば、信号表示灯1Aからの表示状態情報に対応する表示を第1段の表示ユニット21において実行し、信号表示灯1Bからの表示状態情報に対応する表示を第2段の表示ユニット22において実行し、信号表示灯1Cからの表示状態情報に対応する表示を第3段の表示ユニット23において実行する。たとえば、管理用信号表示灯100は、信号表示灯1Aから与えられる表示状態情報のうち、点灯領域の大きさに関する情報(液量情報)に対応する時間間隔で第1段の表示ユニット21を点滅させてもよい。また、信号表示灯100は、信号表示灯1Aから与えられる表示状態情報のうち、点灯色に関する情報(液温情報)に基づいて、第1段の表示ユニット21の点灯色を定めてもよい。第2段および第3段の表示ユニット23についても、信号表示灯1B,1Cから得られる表示状態情報に基づいて、同様に表示状態が設定されればよい。 For example, the management signal indicator lamp 100 executes display corresponding to the display state information from the signal indicator lamp 1A in the first-stage display unit 21, and displays the display corresponding to the display state information from the signal indicator lamp 1B. It is executed in the display unit 22 of the second stage, and the display corresponding to the display state information from the signal indicator lamp 1C is executed in the display unit 23 of the third stage. For example, the management signal indicator lamp 100 blinks the first-stage display unit 21 at a time interval corresponding to information (liquid amount information) related to the size of the lighting area among the display state information given from the signal indicator lamp 1A. You may let them. Moreover, the signal indicator lamp 100 may determine the lighting color of the first-stage display unit 21 based on information (liquid temperature information) regarding the lighting color among the display state information provided from the signal indicator lamp 1A. The display states of the second and third display units 23 may be similarly set based on the display state information obtained from the signal indicator lamps 1B and 1C.
 こうして、管理用信号表示灯100は、複数の信号表示灯1A,1B,1Cの表示状態を集約して表示する。そして、管理用信号表示灯100の各段の表示ユニット21,22,23は、点滅間隔および点灯色によって、それぞれ、2種類の物理量(液量および液温)を表現する表示状態となる。 Thus, the management signal indicator lamp 100 collectively displays the display states of the plurality of signal indicator lamps 1A, 1B, and 1C. The display units 21, 22, and 23 in each stage of the management signal indicator lamp 100 are in a display state that expresses two types of physical quantities (liquid amount and liquid temperature), respectively, according to the blinking interval and the lighting color.
 なお、信号表示灯1A,1B,1Cから管理用信号表示灯100に送信される表示状態情報としては、センサ81,82の検出信号に対応した液量データおよび液温データを用いてもよい。この場合、管理用信号表示灯100は、それらのデータに基づいて、各表示ユニット20の表示状態を決定する。 In addition, as the display state information transmitted from the signal indicator lamps 1A, 1B, and 1C to the management signal indicator lamp 100, liquid volume data and liquid temperature data corresponding to the detection signals of the sensors 81 and 82 may be used. In this case, the management signal indicator lamp 100 determines the display state of each display unit 20 based on the data.
 以上、この発明の実施形態について説明してきたが、この発明は、さらに他の形態で実施することもできる。 Although the embodiments of the present invention have been described above, the present invention can also be implemented in other forms.
 たとえば、信号表示灯1A,1B,1Cにおいて「エラー1」、「エラー2」および「正常」の表示を行う場合(図9参照)に、3つの信号表示灯1A,1B,1Cを管理用信号表示灯100の3つの表示ユニット21,22,22にそれぞれ対応付けて集約表示してもよい。すなわち、表示ユニット21は信号表示灯1Aの表示状態を表現し、表示ユニット22は信号表示灯1Bの表示状態を表現し、表示ユニット23は信号表示灯1Cの表示状態を表現する。各表示ユニット20における表示は、表示内容に応じて点滅間隔を異ならせた点滅表示、表示内容に応じて点灯色を異ならせたカラー表示などであってもよい。 For example, when “error 1”, “error 2”, and “normal” are displayed on the signal indicators 1A, 1B, and 1C (see FIG. 9), the three signal indicators 1A, 1B, and 1C are used as management signals. The three display units 21, 22, and 22 of the indicator lamp 100 may be displayed in association with each other. That is, the display unit 21 expresses the display state of the signal indicator lamp 1A, the display unit 22 expresses the display state of the signal indicator lamp 1B, and the display unit 23 expresses the display state of the signal indicator lamp 1C. The display in each display unit 20 may be a blinking display with different blinking intervals according to display contents, a color display with different lighting colors according to display contents, or the like.
 また、前述の実施形態では、複数の信号表示灯1の表示状態情報が管理用信号表示灯100に送信される例を示したが、一つの信号表示灯1から管理用信号表示灯100に表示状態情報が送信され、管理用信号表示灯100が信号表示灯1とは異なる表示状態に制御されてもよい。生産装置が配置された現場で必要とされる情報と、管理者が必要とする情報とは異なるので、このような構成が適切な場合もある。 In the above-described embodiment, an example in which the display state information of the plurality of signal indicator lamps 1 is transmitted to the management signal indicator lamp 100 is shown. The state information may be transmitted, and the management signal indicator lamp 100 may be controlled to a display state different from that of the signal indicator lamp 1. Such information may be appropriate because the information required at the site where the production apparatus is located is different from the information required by the manager.
 また、ネットワーク3に管理用情報処理装置(情報処理端末装置10であってもよい。)を接続し、この管理用情報処理装置に一部または全部の信号表示灯1の表示状態情報が送信されて登録されるようにしてもよい。この場合、管理用信号表示灯100は、ミラーリング元の信号表示灯1の表示状態情報を管理用情報処理装置を介して取得することができる。すなわち、ミラーリング元(信号表示灯1)からミラーリング先(管理用信号表示灯100)への表示状態情報の送信が、管理用情報処理装置を介して行われる。 Further, a management information processing apparatus (which may be the information processing terminal apparatus 10) is connected to the network 3, and display state information of part or all of the signal indicator lamps 1 is transmitted to the management information processing apparatus. May be registered. In this case, the management signal indicator lamp 100 can acquire the display state information of the mirroring source signal indicator lamp 1 via the management information processing apparatus. In other words, display state information is transmitted from the mirroring source (signal display lamp 1) to the mirroring destination (management signal display lamp 100) via the management information processing apparatus.
 さらに、前述の実施形態では、生産装置A~Cの間を接続するネットワーク3を利用して、複数の信号表示灯1および管理用信号表示灯100が通信可能に接続されているが、むろん、生産装置A~Cを接続するネットワークと、複数の信号表示灯1および管理用信号表示灯100を接続するネットワークを別に設けてもよい。 Furthermore, in the above-described embodiment, the plurality of signal indicator lamps 1 and the management signal indicator lamps 100 are communicably connected using the network 3 that connects the production apparatuses A to C. Of course, A network for connecting the production apparatuses A to C and a network for connecting the plurality of signal indicator lamps 1 and the management signal indicator lamp 100 may be provided separately.
 本発明の実施形態について詳細に説明してきたが、これらは本発明の技術的内容を明らかにするために用いられた具体例に過ぎず、本発明はこれらの具体例に限定して解釈されるべきではなく、本発明の範囲は添付の請求の範囲によってのみ限定される。 Although the embodiments of the present invention have been described in detail, these are merely specific examples used to clarify the technical contents of the present invention, and the present invention is construed to be limited to these specific examples.
