警報センサシステムAlarm sensor system
　本発明は、生産施設に使用される機械装置の稼動率を把握するために、それら装置に設けられた警報用の表示灯が発する情報を集約する警報センサシステムに関する。 The present invention relates to an alarm sensor system that aggregates information emitted by warning indicator lamps provided in such devices in order to grasp the operating rate of mechanical devices used in production facilities.
　機械装置による自動生産のコスト低減には、それら装置の稼働率を上げることが重要となるが、そのためには、まず、稼働率を把握する必要がある。そして、その稼働率の把握には、機械装置が稼動していること或は停止していることを示す情報を、その機械装置から得る必要があるが、機械装置がそのような情報を送出するための技術は、これまでにも提案されている。 In order to reduce the cost of automatic production by mechanical devices, it is important to increase the operating rate of these devices. For this purpose, it is necessary to first grasp the operating rate. In order to grasp the operating rate, it is necessary to obtain information indicating that the machine is operating or stopped from the machine, and the machine sends such information. Techniques for this have been proposed.
　例えば、特開２００１‐１７７２９９号公報には、電子部品などを電子機器に実装するマウンターやその周辺機器からなる実装システムなどの自動生産ラインに用いられる情報通知機能を有する製造装置が開示されている。 For example, Japanese Patent Laid-Open No. 2001-177299 discloses a manufacturing apparatus having an information notification function used in an automatic production line such as a mounter for mounting electronic components or the like on an electronic device or a mounting system including peripheral devices. .

　しかしながら、実際の生産施設において使用される機械装置は、その生産機種が多様である場合が多く、また、生産機種が同じであってもメーカによる違いや、新機種と旧機種との違いなどがある場合も多い。更に、国内製品と海外製品との違いがある場合も多く、機械装置の仕様が統一されていないのが実情である。 However, the machines used in actual production facilities often have a wide variety of production models. Even if the production models are the same, there are differences between manufacturers and differences between new and old models. There are many cases. Furthermore, there are many cases where there is a difference between domestic products and overseas products, and the actual situation is that the specifications of the mechanical devices are not unified.
　そのため、全ての機械装置が情報通知機能を備えているとは限らず、また、情報通知機能を備えていたとしてもその情報通知の方式が同一であるとは限らず、全ての機械装置から、機械装置が稼動していること或は停止していることを示す情報を得ることは難しかった。 Therefore, not all mechanical devices have an information notification function, and even if it has an information notification function, the information notification method is not necessarily the same, from all mechanical devices, It was difficult to obtain information indicating that the machine was operating or stopped.
　そこで、本発明は、機械装置が稼動していること或は停止していることを示す情報を、その機械装置の仕様によることなく得ることができる警報センサシステムを提供することを目的とする。 Therefore, an object of the present invention is to provide an alarm sensor system capable of obtaining information indicating that a machine device is operating or stopped without depending on the specifications of the machine device.
　本発明に係る警報センサシステムは、単一または任意の複数の位置で発光する単一または複数の警報表示灯と、受光素子を備えた単一または複数の検出器と、前記複数の検出器の共通導体と、前記複数の検出器に接続されるコントローラと、前記コントローラの上位機器と、を備える。そして、前記複数の検出器が、前記警報表示灯における各発光位置または任意の発光位置に対応して配置され、前記警報表示灯の発光を受けた前記検出器から、前記警報表示灯の発光位置に対応する発光情報信号が送出され、前記コントローラが前記発光情報信号を収集して前記上位機器に引き渡す。 An alarm sensor system according to the present invention includes a single or a plurality of alarm indicator lights that emit light at a single or any plurality of positions, a single or a plurality of detectors including a light receiving element, and a plurality of the detectors. A common conductor; a controller connected to the plurality of detectors; and a host device of the controller. The plurality of detectors are arranged corresponding to each light emission position or any light emission position in the alarm indicator light, and from the detector that has received the light emission of the alarm indicator light, the light emission position of the alarm indicator light The light emission information signal corresponding to is sent, and the controller collects the light emission information signal and delivers it to the host device.
　なお、本発明において、警報表示灯とは、色彩の異なる複数の表示灯が積層されたものである。生産用の機械装置に広く一般的に採用されている、公知の、所謂積層表示灯が好適である。ただし、積層される表示灯の数に制限はなく任意でよく、或は、単一（点灯の有無のみで警報を示すもの）であってもよい。 In the present invention, the warning indicator lamp is a laminate of a plurality of indicator lights having different colors. A known so-called laminated indicator lamp, which is widely used in production machinery, is preferred. However, the number of indicator lamps to be stacked is not limited and may be arbitrary, or may be single (indicating an alarm only by lighting or not).
　前記コントローラが、前記警報表示灯における各発光位置の動作定義に基づいて、前記発光情報信号のデータを、前記動作定義毎に振り分け、前記上位機器へ送出する信号に変換するものであってもよい。 The controller may divide the data of the light emission information signal for each operation definition based on the operation definition of each light emission position in the alarm indicator lamp, and convert the data into a signal to be sent to the host device. .
　本発明によれば、警報表示灯における各発光位置または任意の発光位置に対応して配置され、受光素子を備える検出器が、警報表示灯の発光位置に対応する発光情報信号を送出し、その発光情報信号がコントローラを介して上位機器に引き渡されるため、警報表示灯の点灯の有無や、点灯している場合には点灯位置の情報を継続的に得ることができる。しかも、警報表示灯は、ほとんどの機械装置に取り付けられており、その「警報」の表示は世界的にほぼ同じものと、具体的には、赤表示が非常停止を、黄表示が警告を、緑表示が正常を意味するものとなっている。すなわち、どのような仕様の機械装置においても、緑表示に対応する発光情報信号はその装置が稼動していることを示すものとなり、赤表示に対応する発光情報信号はその装置が停止していることを示すものとなる。従って、機械装置が稼動していること或は停止していることを示す情報を、その機械装置の仕様によることなく得ることが可能となる。 According to the present invention, a detector that is arranged corresponding to each light emission position or any light emission position in the alarm indicator lamp and includes a light receiving element sends out a light emission information signal corresponding to the light emission position of the alarm indicator lamp, Since the light emission information signal is handed over to the host device via the controller, it is possible to continuously obtain information on whether or not the alarm indicator lamp is lit and when it is lit. Moreover, warning indicator lights are attached to almost all mechanical devices, and their "alarm" indications are almost the same worldwide. Specifically, red indication indicates an emergency stop, yellow indication indicates a warning, Green display means normal. That is, in any mechanical device, the light emission information signal corresponding to the green display indicates that the device is in operation, and the light emission information signal corresponding to the red display is that the device is stopped. It will be shown. Therefore, it is possible to obtain information indicating that the machine device is operating or stopped without depending on the specifications of the machine device.
　また、コントローラが、警報表示灯における各発光位置の動作定義に基づいて、発光情報信号のデータを、動作定義毎に振り分け、上位機器へ送出する信号に変換するものであれば、上位機器に対する大幅な修正変更を行なうことなく、既存の施設に適応することが可能となる。 In addition, if the controller distributes the light emission information signal data for each operation definition based on the operation definition of each light emitting position in the warning indicator lamp and converts it into a signal to be sent to the host device, it will greatly It is possible to adapt to existing facilities without making any necessary modifications.

It has become. However, the structure for attaching the detector 2 to the common conductor 3 is not limited. For example, the common conductor 3 may be formed of a material having a certain degree of flexibility such as a synthetic resin, and a pin may protrude from the back surface of the detector 2 and may be attached by piercing the pin.
　検出器２は、警報表示灯１Ａ、１Ｂ、１Ｃの各表示灯１１ａ、１１ｂ、１１ｃ、１１ｄ、１１ｅに対応する位置に取り付けられており、警報表示灯１Ａ、１Ｂまたは１Ｃからの発光を受ける検出用受光部２２と、自局の固有識別情報（例えば自局アドレス情報、型式情報、仕様情報など）を表示する別体の表示器６との通信を行う通信用投光部２３及び通信用受光部２４を備える。また、検出器２は、内部回路としてマイクロコンピュータ・コントロール・ユニットであるＭＣＵ２５を備える。ＭＣＵ２５は、図３に示すように、ＣＰＵ、ＲＡＭ、ＲＯＭを備え、ＲＯＭには検出処理や表示器６との通信に必要なプログラムと、自局のアドレスデータや機器仕様等の固有識別情報が記憶されている。また、検出データがＲＡＭに記憶され、ＣＰＵの演算機能を用いて、検出に必要な情報を得るための処理が行なわれるものとなっている。具体的には、まず、検出用受光部２２の検出情報が入力端子ＩＮＳからＭＣＵ２５へ入力され、その入力が検出データとしてＲＡＭに記憶されることになる。また、通信用受光部２４で受けた信号は、入力端子ＩＮＡからＭＣＵ２５へ入力され、その信号に応じて固有識別情報のデータが出力端子ＬＥＡを介し通信用投光部２３に出力され、投光信号が発信される。 The detector 2 is attached at a position corresponding to each of the indicator lamps 11a, 11b, 11c, 11d, and 11e of the alarm indicator lights 1A, 1B, and 1C, and detects the light emitted from the alarm indicator lights 1A, 1B, and 1C. Communication light receiving unit 22 and communication light projecting unit 23 for communicating with the separate display 6 for displaying the local identification information (for example, local station address information, model information, specification information, etc.) The unit 24 is provided. The detector 2 includes an MCU 25 that is a microcomputer control unit as an internal circuit. As shown in FIG. 3, the MCU 25 includes a CPU, a RAM, and a ROM. The ROM includes a program necessary for detection processing and communication with the display 6, and unique identification information such as address data of the own station and device specifications. It is remembered. Also, the detection data is stored in the RAM, and processing for obtaining information necessary for detection is performed using the arithmetic function of the CPU. Specifically, first, detection information of the detection light receiving unit 22 is input from the input terminal INS to the MCU 25, and the input is stored in the RAM as detection data. The signal received by the communication light receiving unit 24 is input to the MCU 25 from the input terminal INA, and the data of the unique identification information is output to the communication light projecting unit 23 via the output terminal LEA according to the signal, and the light is emitted. A signal is emitted.
　検出器２の検出データは、警報表示灯１Ａ、１Ｂまたは１Ｃの発光情報信号として、共通データ信号線ＤＰ、ＤＮに接続されているコントローラ４へ送出される。信号の送出にあたっては、ＭＣＵ２５のＲＡＭに記憶されている検出データに相応する信号が、出力端子ＯＵＴからトランジスタＴＲのベースへ出力される。具体的には、検出データが”ｏｎ”（検出器２の対応する表示灯１１ａ、１１ｂ、１１ｃ、１１ｄ、又は１１ｅが点灯したことを示すもの）であれば、トランジスタＴＲがｏｎとなり、電流が流れることで電圧が降下し、電圧レベルが０Ｖとなり、発光情報信号として共通データ信号線ＤＰ、ＤＮ上に送出される。 The detection data of the detector 2 is sent to the controller 4 connected to the common data signal lines DP and DN as a light emission information signal of the alarm indicator lamps 1A, 1B or 1C. In transmitting the signal, a signal corresponding to the detection data stored in the RAM of the MCU 25 is output from the output terminal OUT to the base of the transistor TR. Specifically, if the detection data is “on” (indicating that the corresponding indicator lamp 11a, 11b, 11c, 11d, or 11e of the detector 2 is lit), the transistor TR is turned on and the current is By flowing, the voltage drops, the voltage level becomes 0V, and is sent as a light emission information signal onto the common data signal lines DP and DN.
　コントローラ４は、上位機器５に接続されており、検出器２から送出された発光情報信号のデータ（発光情報データ）５４を上位機器５に引き渡す。上位機器５は、例えばコンピュータ等であり、検出器２に対する制御データ５３を送出する出力ユニット５１と、発光情報データ５４を受け取る入力ユニット５２を有している。コントローラ４は、これら出力ユニット５１と入力ユニット５２に接続されている。 The controller 4 is connected to the host device 5 and hands over the light emission information signal data (light emission information data) 54 sent from the detector 2 to the host device 5. The host device 5 is, for example, a computer or the like, and has an output unit 51 that sends control data 53 to the detector 2 and an input unit 52 that receives the light emission information data 54. The controller 4 is connected to the output unit 51 and the input unit 52.
　コントローラ４は、また、所定のタイミング信号に基づき一連のパルス状信号を生成し、この信号を共通データ信号線ＤＰ、ＤＮに送出している。以下、共通データ信号線ＤＰ、ＤＮに送出される一連のパルス状信号を、伝送クロック信号というものとする。 The controller 4 also generates a series of pulse signals based on a predetermined timing signal, and sends this signal to the common data signal lines DP and DN. Hereinafter, a series of pulse signals transmitted to the common data signal lines DP and DN are referred to as transmission clock signals.
　伝送クロック信号をなす一連のパルス状信号は、図４に示すように、信号の始まりを示すスタート信号（ＳＴＢ）に続けられており、各１周期が複数の検出器２のいずれか一つに割り当てられている。例えば、図４に示す例では、スタート信号に続く５つの周期が警報表示灯１Ａに割り当てられており、スタート信号直後の周期が警報表示灯１Ａの表示灯１１ａに、続く周期が同じ警報表示灯１Ａの表示灯１１ｂに、そして、以降も同様に表示灯１１ｅまで、５つ目までの周期が割り当てられている。 As shown in FIG. 4, a series of pulse signals constituting the transmission clock signal is followed by a start signal (STB) indicating the start of the signal, and each period is assigned to one of the plurality of detectors 2. Assigned. For example, in the example shown in FIG. 4, five cycles following the start signal are assigned to the alarm indicator lamp 1A, the cycle immediately after the start signal is the indicator lamp 11a of the alarm indicator lamp 1A, and the following cycle is the same. Up to the fifth cycle is assigned to the indicator lamp 11b of 1A and thereafter to the indicator lamp 11e in the same manner.
　一方、この伝送クロック信号の１周期は、その後半が高電位レベル（この実施例では＋２４Ｖ）と、前半が低電位レベルとされている。そして、低電位レベルは、データ値”０”を表すレベルと、そのレベルとは異なる、データ値”１”を表すレベルの２つのレベルで構成され（この実施例では＋１２Ｖまたは０Ｖ）、当該周期の割り振られた検出器２の検出データに応じて変調される。例えば、図４に示す例では、警告表示灯１Ａの表示灯１１ａが点灯した場合には、その表示灯１１ａに対応する検出器２において、前記ＭＣＵ２５　の出力端子ＯＵＴａ（図４において、表示灯１１ａに対応する検出器２の出力端子をＯＵＴａとし、ＯＵＴｂ、ＯＵＴｃ、ＯＵＴｄ、ＯＵＴｅについても、同様とする。）の出力電圧が上がり、その結果として、伝送クロック信号の当該周期の低電圧レベルが０Ｖとなる。表示灯１１ｂ、１１ｃ、１１ｄ、１１ｅについても同様に、出力端子ＯＵＴｂ、ＯＵＴｃ、ＯＵＴｄ、ＯＵＴｅの出力がそれぞれ有効となる。 On the other hand, in one cycle of this transmission clock signal, the latter half is set to the high potential level (+24 V in this embodiment) and the first half is set to the low potential level. The low potential level is composed of two levels, ie, a level representing the data value “0” and a level representing the data value “1”, which is different from the level (in this embodiment, + 12V or 0V), and this cycle. Are modulated according to the detection data of the allocated detectors 2. For example, in the example shown in FIG. 4, when the indicator lamp 11a of the warning indicator lamp 1A is turned on, the output terminal OUTa of the MCU 25 (the indicator lamp 11a in FIG. 4) is detected in the detector 2 corresponding to the indicator lamp 11a. The output voltage of the detector 2 corresponding to the above is set to OUTa, and the same applies to OUTb, OUTc, OUTd, and OUTe.) As a result, the low voltage level of the cycle of the transmission clock signal is 0V. It becomes. Similarly, the outputs from the output terminals OUTb, OUTc, OUTd, and OUTe are also valid for the indicator lamps 11b, 11c, 11d, and 11e.
　すなわち、この伝送クロック信号の各周期の低電位レベル期間に、検出器２からの発光情報信号が重畳されることとなる。そこで、この低電位レベルの表すデータ値（発光情報信号のデータ）を、警報表示灯１Ａ、１Ｂ、１Ｃにおける各発光位置の動作定義に基づいて、それら動作定義毎に振り分けることにより、機械装置が稼動していること或は停止していることを示す情報を得ることが可能となる。例えば、スタート信号直後の周期のデータ値が、警報表示灯１Ａにおいて非常停止を示す赤色に対応するものであり、スタート信号から３つ目の周期のデータ値が、警報表示灯１Ａにおいて正常を示す緑色に対応するものであることを、上位機器５に定義しておく。すると、上位機器５では、警報表示灯１Ａに対応する機械装置について、スタート信号直後の周期の発光情報信号のデータ値が”ｏｎ”であれば停止しており、スタート信号から３つ目の周期の発光情報信号のデータ値が”ｏｎ”であれば可動しているという情報を得ることができる。なお、図４では、図示の便宜上、警報表示灯１Ａにおいて全ての出力端子ＯＵＴａ、ＯＵＴｂ、ＯＵＴｃ、ＯＵＴｄ、ＯＵＴｅが有効とされているが、実際には、点灯している表示灯に対応する一つ或は複数の出力端子のみが有効となる。 That is, the light emission information signal from the detector 2 is superimposed in the low potential level period of each cycle of the transmission clock signal. Therefore, by distributing the data value represented by the low potential level (data of the light emission information signal) to each operation definition based on the operation definition of each light emitting position in the alarm indicator lamps 1A, 1B, and 1C, the mechanical device It is possible to obtain information indicating that it is operating or stopped. For example, the data value in the cycle immediately after the start signal corresponds to red indicating an emergency stop in the alarm indicator lamp 1A, and the data value in the third cycle from the start signal indicates normal in the alarm indicator light 1A. It is defined in the upper device 5 that it corresponds to green. Then, the host device 5 stops if the data value of the light emission information signal in the cycle immediately after the start signal is “on” for the mechanical device corresponding to the alarm indicator lamp 1A, and the third cycle from the start signal. If the data value of the light emission information signal is “on”, information indicating that it is movable can be obtained. In FIG. 4, for convenience of illustration, all the output terminals OUTa, OUTb, OUTc, OUTd, and OUTe are valid in the alarm indicator lamp 1A, but in actuality, one corresponding to the lit indicator lamp. Only one or more output terminals are valid.
　発光情報信号のデータの、警報表示灯１Ａ、１Ｂ、１Ｃにおける各発光位置の動作定義毎への振り分け処理は、コントローラ４で行なうこととしてもよい。この場合、コントローラ４は、発光情報データ５４に代えて、各警報表示等１Ａ、１Ｂ、１Ｃの状態（非常停止、正常など）を、上位機器５に伝えることになる。 The controller 4 may perform the process of distributing the data of the light emission information signal for each operation definition of each light emission position in the alarm indicator lights 1A, 1B, 1C. In this case, instead of the light emission information data 54, the controller 4 informs the host device 5 of the state of each alarm display 1A, 1B, 1C (emergency stop, normal, etc.).
　検出器２は、表示灯１１ａ、１１ｂ、１１ｃ、１１ｄ、１１ｅの視認性を損なわない程度の大きさ、具体的には、表示灯１１ａ、１１ｂ、１１ｃ、１１ｄ、１１ｅの正面視の面積に対する面積比が２０分の１程度とされている。そのため、検出器２の仕様を知るための機器番号等の固有識別情報を表示することができない。そこで、この検出器２の固有識別情報は、検出器２と別体の表示器６に表示されるものとなっている。 The detector 2 has a size that does not impair the visibility of the indicator lamps 11a, 11b, 11c, 11d, and 11e. Specifically, the area of the indicator lamps 11a, 11b, 11c, 11d, and 11e with respect to the area of the front view. The ratio is about 1/20. Therefore, unique identification information such as a device number for knowing the specification of the detector 2 cannot be displayed. Therefore, the unique identification information of the detector 2 is displayed on the display 6 separate from the detector 2.
　表示器６は、送受信部６１、入力部６２、表示部６３を備え、また、これらの制御を行なうＭＣＵ６５を有している。これらは、いずれも公知の部品や回路で構成することができるため詳細な説明は省略し、その機能の概略についてのみ簡単に説明する。送受信部６１は、投光素子と受光素子を備え、所望の検出器２に向けられた場合、検出器２の通信用受光部２４に対しコマンド信号を発し、或は、検出器２の通信用投光部２３から発せられた、固有識別情報を含む投光信号を受信する。検出器２に対するコマンド信号は、その内容、例えば、通信対象となる検出器２のアドレスを入力部６２から入力するものとなっている。また、送受信部６１で受信した光信号のデータ、すなわち、固有識別情報が表示部６３に表示される。 The display device 6 includes a transmission / reception unit 61, an input unit 62, and a display unit 63, and also includes an MCU 65 that performs these controls. Since any of these can be configured with known components and circuits, a detailed description thereof will be omitted, and only an outline of the function will be briefly described. The transmission / reception unit 61 includes a light projecting element and a light receiving element, and when directed to a desired detector 2, issues a command signal to the communication light receiving unit 24 of the detector 2, or for communication of the detector 2. A projection signal including unique identification information, which is emitted from the projection unit 23, is received. The command signal for the detector 2 is input from the input unit 62 with its contents, for example, the address of the detector 2 to be communicated. Further, data of the optical signal received by the transmission / reception unit 61, that is, unique identification information is displayed on the display unit 63.
　なお、表示器６は、検出器２と非接触で情報の授受を行なう機能を果たすものであれば、構造等に制限はなく、例えば、検出器２との通信は、光ではなく電波を利用するものであってもよい。ただし、この場合、検出器２にも、電波を送受信する機能を備える必要がある。 The display 6 is not limited in its structure and the like as long as it functions to exchange information without contact with the detector 2. For example, communication with the detector 2 uses radio waves instead of light. You may do. However, in this case, the detector 2 also needs to have a function of transmitting and receiving radio waves.
　この実施例では、警報表示等１Ａ、１Ｂ、１Ｃの全ての表示等１１a、１１ｂ、１１ｃ、１１ｄ、１１ｅに対して検出器２が取付けられているが、任意の表示灯に対してのみ取り付けることとしてもよい。例えば、正常に可動している情報のみが得られればよい場合には、検出器２を表示灯１１ｃに対してのみ取り付けることもできる。この場合、検出器２の数が減ることからシステム構成が簡単になり、また、伝送クロック信号の１伝送周期も短くなり、伝送速度を上げることができる利点がある。 In this embodiment, the detector 2 is attached to all indications 11a, 11b, 11c, 11d, and 11e such as alarm indications 1A, 1B, and 1C. It is good. For example, when it is sufficient to obtain only normally moving information, the detector 2 can be attached only to the indicator lamp 11c. In this case, since the number of detectors 2 is reduced, the system configuration is simplified, and one transmission cycle of the transmission clock signal is shortened, and there is an advantage that the transmission speed can be increased.
