Description

本発明は、工場や物流拠点等、主に工場において、素材、半製品又は製品が流れる複数のライン中に異常が生じた際に、その異常状態を作業者に通知するライン異常通知システムの改良に関するものである。   The present invention is an improvement of a line abnormality notification system for notifying an operator of an abnormal state when abnormality occurs in a plurality of lines through which materials, semi-finished products or products flow mainly in factories, distribution bases, etc. It is about.

従来、この種の技術としては、特許文献1に記載のアンドン情報表示装置が開発されていた。これは、自動車の製造等を行う工場における複数の生産ラインの稼働状況を容易に把握し、各生産ラインにおける異常の有無に関する情報を、生産ライン近傍の上方に設置された所謂アンドン(行灯)を用い、面発光により表示するというものである。   Conventionally, as this type of technology, an ANDON information display device described in Patent Document 1 has been developed. This makes it easy to grasp the operational status of multiple production lines in a factory that manufactures automobiles, etc., and to provide information on the presence or absence of abnormalities in each production line using the so-called ANDON (row lights) installed above the vicinity of production lines It is used to display by surface emission.

特開2011−95606号公報JP 2011-95606 A

しかしながら上記従来技術では、異常情報の表示が固定位置、つまりアンドン設置位置でなされるので、どうしても見えにくい位置が生じてしまう。また、大規模の生産ラインにおいては、情報表示位置(アンドン設置位置)まで遠距離となり、情報表示が見えにくくなったり、見誤る虞がある。更には、近年の1生産ライン当たりの作業員数の減少から、作業員の巡回タイミングによっては表示情報の見落としが生じたり、異常情報表示の早期発見が困難になる等の虞もある。   However, in the above-described prior art, the display of abnormality information is performed at a fixed position, that is, an ANDON installation position, so that a position that is difficult to see is inevitably generated. In a large-scale production line, the information display position (Andon installation position) is a long distance, and the information display may be difficult to see or may be mistaken. Furthermore, due to the recent decrease in the number of workers per production line, there is a possibility that display information may be overlooked or the early detection of abnormal information display may be difficult depending on the traveling timing of the workers.

本発明は、上記のような実情に鑑みなされたもので、複数のライン中に異常が生じた際に、同異常状態を、そのラインに対する作業者の位置や方向、更には遠近に拘わらず迅速、適確に通知できるライン異常通知システムを提供することを課題とする。   The present invention has been made in view of the above circumstances, and when an abnormality occurs in a plurality of lines, the abnormal state can be quickly detected regardless of the position and direction of the operator with respect to the line, and also the distance. It is an object of the present invention to provide a line abnormality notification system capable of accurately reporting.

A circuit for decoding whether the received synthesized signal sound is one of the above numbers and symbols. The synthesized signal sound is hereinafter referred to as a tone signal.
Each of the controllers 6 and 9 includes a microcomputer (hereinafter referred to as a microcomputer) in which a program and data for performing wireless communication between the master station 1 and each slave station 2 are recorded in an internal memory.

各子局2は、自局が付設されたライン(自ライン)Lの異常状態及び自局の識別番号をコード化したトーン信号を自局のトランシーバ7のマイク端子tbに入力させて親局1に送信可能に構成されている。
ラインLの異常状態は、その種類別に対応付けられた複数、図示例では16個のスイッチ接点s1〜s16の閉動作状態で表される。各スイッチ接点s1〜s16はコントローラ9に接続されていて、その閉動作は手動又はラインLからの信号によって自動で行われる。この16個のスイッチ接点s1〜s16の閉動作状態がコントローラ9に与えられ、コード化されてDTMF信号生成/解読回路8に入力される。そして、このDTMF信号生成/解読回路8により自ラインLの異常状態を表すトーン信号が生成され、自局のトランシーバ7のマイク端子btに入力させて親局1に送信するように構成されている。

親局1において必要なトーン信号の生成及び解読は、親局1に備えられたDTMF信号生成/解読回路8が行う。
なお、親局1のトランシーバ4の送受信の切り替えは、例えば親局1のコントローラ6からのPTT信号を同親局1のトランシーバ4のPTT端子に与えるか、遮断するか(PTT信号のオン、オフ)によって行われる。親局1のトランシーバ4のマイク端子tbにトーン信号が入力されることによって受信状態から送信状態に自動的に切り替わるように構成してもよい。
親局1(トランシーバ4)及び各子局2(トランシーバ7)相互間の無線通信は共通の周波数(チャンネル)で行われる。また、作業者指示用トランシーバ12及び作業者携帯用トランシーバ3相互間の送受信周波数(チャンネル)も共通の周波数(チャンネル)が設定されているが、この周波数は、上記親局1及び各子局2相互間とは異なる周波数が設定されている。親局1及び各子局2相互間の通信と、作業者指示用トランシーバ12及び作業者携帯用トランシーバ3相互間の通信との間の混信を避けるためである。
本実施形態において、各トランシーバ3,4,7,12には、特定小電力トランシーバ(電波法施行規則第6条第4項第2号に規定された無線電話用特定小電力無線局)が用いられている。免許や資格を要することなく使え、小型かつ安価であって、取り扱いも持ち運び移動も簡単だからである。この特定小電力トランシーバは、音声信号の外部出力端子であるイヤホン端子taと外部入力端子であるマイク端子(PTT端子を含む。)tbとを有し、外部から入力されるPTT信号のオン、オフにより送受信状態の切り替え設定が可能である。
The master station 1 performs wireless communication with each slave station 2 in order of slave stations 2-1 → slave stations 2-2... → slave stations 2-5 by transmission / reception signals based on coded tone signals. Then, the abnormal states of the lines L1 to L5 are collected, and the encoded abnormal states of the lines L1 to L5 are converted into specific message voice signals by line and type by the voice synthesis circuit 10. Then, the message voice signal is given to the microphone terminal tb which is the external input terminal of the worker instruction transceiver 12 set to the transmission state by the transmission controller 11 and transmitted to the worker portable transceiver 3. It is configured.
In this embodiment, the transmission controller 11 is configured to return the worker instruction transceiver 12 to the reception state after giving a message voice signal to the microphone terminal tb which is an external input terminal of the worker instruction transceiver 12. .
Generation and decoding of a tone signal required in the master station 1 is performed by a DTMF signal generation / decoding circuit 8 provided in the master station 1.
Note that the transmission / reception switching of the transceiver 4 of the master station 1 is performed by, for example, applying or shutting off the PTT signal from the controller 6 of the master station 1 to the PTT terminal of the transceiver 4 of the master station 1 (ON / OFF of the PTT signal). ). It may be configured to automatically switch from the reception state to the transmission state when a tone signal is input to the microphone terminal tb of the transceiver 4 of the master station 1.
Wireless communication between the master station 1 (transceiver 4) and each slave station 2 (transceiver 7) is performed at a common frequency (channel). Further, a transmission / reception frequency (channel) between the operator instruction transceiver 12 and the worker portable transceiver 3 is also set to a common frequency (channel). This frequency is determined by the master station 1 and each slave station 2. Different frequencies from each other are set. This is to avoid interference between communication between the master station 1 and each slave station 2 and communication between the worker instruction transceiver 12 and the worker portable transceiver 3.
In the present embodiment, each of the transceivers 3, 4, 7, and 12 is a specific low-power transceiver (a specific low-power radio station for wireless telephones stipulated in Article 6, Paragraph 4, Item 2 of the Radio Law Enforcement Regulations). It has been. It is usable without requiring a license or qualification, is small and inexpensive, and is easy to handle, carry and move. This specific low-power transceiver has an earphone terminal ta that is an external output terminal of an audio signal and a microphone terminal (including a PTT terminal) tb that is an external input terminal, and turns on / off a PTT signal input from the outside. The transmission / reception state switching setting can be made by.

次に、上述実施形態の動作について説明する。
いま、親局1及び各子局2の全てのトランシーバ3,4,7,12、コントローラ6,9,11、DTMF信号生成/解読回路5,8、及び親局1の音声合成回路10に電源が投入されているとする。また、各ラインL1〜L5において現在、異常状態が生じていれば、各子局2のスイッチ接点s1〜s16のうち、該当する異常状態に対応するスイッチ接点sが閉動作されているとする。
Next, the operation of the above embodiment will be described.
Now, power is supplied to all the transceivers 3, 4, 7, 12, the controllers 6, 9, 11, the DTMF signal generation / decoding circuits 5, 8, and the speech synthesis circuit 10 of the master station 1. Is input. Further, if an abnormal state is currently occurring in each of the lines L1 to L5, it is assumed that among the switch contacts s1 to s16 of each slave station 2, the switch contact s corresponding to the corresponding abnormal state is closed.

この状態において、親局1は、そのコントローラ6のマイコン内に記録されたプログラムにより、まず、第1子局2-1の識別番号及び第1子局2-1が付設された第1ラインL1の異常状態の報告要求(異常状態報告要求)を送信する。この送信は、第1子局2-1の識別番号及び異常状態報告要求をコード化したトーン信号を、親局1のDTMF信号生成/解読回路8から送信状態にある親局1のトランシーバ4のマイク端子tbに入力させて行われる。この異常状態報告要求は、第1子局2-1だけが認識し応答可能である。
すなわち、親局1から第1子局2-1の識別番号を送信すると、第1子局2-1はそのトランシーバ9のイヤホン端子から第1子局2-1の識別番号及び異常状態報告要求に係るトーン信号が第1子局2-1のDTMF信号生成/解読回路8によって解読される。そして、そのコントローラ9によって自局に異常状態報告要求があることが了解される。
コントローラ9は、16個のスイッチ接点s1〜s16のうち、閉動作されているスイッチ接点sにつき、それが、あるいはそれらが何番目のスイッチ接点sであるかをコード化し、DTMF信号生成/解読回路8により自ラインL1の異常状態を表すトーン信号として生成させる。そしてそのトーン信号を、送信状態に切り替えられた自局のトランシーバ7のマイク端子tbに入力させ送信させる。
In this state, the master station 1 starts with the first line L1 to which the identification number of the first slave station 2-1 and the first slave station 2-1 are attached according to the program recorded in the microcomputer of the controller 6. An abnormal condition report request (abnormal condition report request) is transmitted. In this transmission, the tone signal in which the identification number of the first slave station 2-1 and the abnormal condition report request are encoded is transmitted from the DTMF signal generation / decoding circuit 8 of the master station 1 to the transceiver 4 of the master station 1 in the transmission state. This is performed by inputting to the microphone terminal tb. Only the first slave station 2-1 can recognize and respond to this abnormal condition report request.
That is, when the master station 1 transmits the identification number of the first slave station 2-1, the first slave station 2-1 receives the identification number of the first slave station 2-1 and the abnormal state report request from the earphone terminal of the transceiver 9. Is decoded by the DTMF signal generation / decoding circuit 8 of the first slave station 2-1. Then, it is understood by the controller 9 that there is an abnormal state report request to the own station.
The controller 9 encodes the switch contact s that is closed among the 16 switch contacts s1 to s16 or the switch contact s of the switch contact s, and generates a DTMF signal generation / decoding circuit. 8 is generated as a tone signal indicating an abnormal state of the own line L1. Then, the tone signal is input to the microphone terminal tb of the transceiver 7 of the own station that has been switched to the transmission state and transmitted.

親局1は、そのコントローラ6のマイコン内に記録されたプログラムにより、第1子局2-1から送信された信号をDTMF信号生成/解読回路5によって解読させ、第1ラインL1の異常状態とその種類を判定する。そして、その判定結果、つまりラインが第1ラインL1であることと、どの種類の異常状態が発生しているかをコード化した信号を音声合成回路10に入力させ、その判定結果に応じたメッセージ音声信号を音声合成回路10から出力させる。
音声合成回路10から出力したメッセージ音声信号は、送信コントローラ11によって送信状態に設定された(PTT信号がオンされた)作業者指示用トランシーバ12のマイク端子tbに与えられ、作業者携帯用トランシーバ3に対して送信される。送信コントローラ11はメッセージ音声信号を作業者指示用トランシーバ12の外部入力端子であるマイク端子tbに与えた後、作業者指示用トランシーバ12を受信状態に戻す(PTT信号をオフする)。
作業者携帯用トランシーバ3は、通常、受信状態に設定されており、作業者Wは、その作業者携帯用トランシーバ3の内部スピーカから第1ラインL1でどの種類の異常状態が発生しているかを、メッセージ音声で通知される。例えば、「第1ラインで作業遅延発生」、「第1ラインで材料待ち発生」あるいは「第1ラインで故障発生」等のメッセージ音声で通知される。通常、通知は一定時間又は一定回数繰り返される。
作業者Wは、このようなメッセージ音声に応じて異常状態に対処すべき場所、ここでは第1ラインL1に向かい、所定の対処をする。作業者Wは、第1ラインL1に対する位置や方向、更には遠近に拘わらず迅速、適確に通知を受けることができる。
The master station 1 causes the DTMF signal generation / decoding circuit 5 to decode the signal transmitted from the first slave station 2-1 by the program recorded in the microcomputer of the controller 6, and detects the abnormal state of the first line L 1. The type is determined. Then, the determination result, that is, a signal in which the line is the first line L1 and what kind of abnormal state is generated is input to the speech synthesis circuit 10, and the message voice corresponding to the determination result is input. The signal is output from the speech synthesis circuit 10.
The message voice signal output from the voice synthesizing circuit 10 is given to the microphone terminal tb of the worker instruction transceiver 12 set to the transmission state by the transmission controller 11 (PTT signal is turned on), and the worker portable transceiver 3 Sent to. The transmission controller 11 gives the message voice signal to the microphone terminal tb which is an external input terminal of the worker instruction transceiver 12, and then returns the worker instruction transceiver 12 to the reception state (turns off the PTT signal).
The worker portable transceiver 3 is normally set in a reception state, and the worker W determines which type of abnormal state is occurring in the first line L1 from the internal speaker of the worker portable transceiver 3. , Is notified by message voice. For example, a message voice such as “work delay occurred on the first line”, “material waiting occurred on the first line”, or “failure occurred on the first line” is notified. Usually, the notification is repeated for a certain time or a certain number of times.
The worker W goes to a place to deal with the abnormal state according to such a message voice, here, toward the first line L1, and takes a predetermined action. The operator W can be notified promptly and accurately regardless of the position and direction with respect to the first line L1, and the distance.

親局1は、上記のように判定された第1ラインL1の異常状態とその種類(判定結果)を音声合成回路10に入力させると、そのコントローラ6内のプログラムにより決められた順序に従ったラインL、通常、第2ラインL2の異常状態報告要求を送信する。この送信時の動作、及び送信された異常状態報告要求が、この異常状態報告要求と共に送信された子局2の識別番号に該当する第2子局2-1だけが認識し、親局1に対して応答可能であること、また応答の動作順序、内容等、上記第1子局2-1の場合と同様である。
また上記応答を受けた親局1の動作、つまり、第2ラインL2の異常状態とその種類を判定し、判定結果を音声合成回路10に入力させてそれに応じたメッセージ音声信号を作業者指示用トランシーバ12に与え、作業者携帯用トランシーバ3に送信させること等も上記第1子局2-1の場合と同様である。
作業者Wは、作業者携帯用トランシーバ3の内部スピーカから第2ラインL2でどの種類の異常状態が発生しているかをメッセージ音声で通知され、上記第1子局2-1の場合と同様に所定の対処をする。
When the master station 1 inputs the abnormal state and the type (determination result) of the first line L1 determined as described above to the speech synthesis circuit 10, the master station 1 follows the order determined by the program in the controller 6. An abnormal condition report request for the line L, usually the second line L2, is transmitted. The operation at the time of transmission and the transmitted abnormal state report request are recognized only by the second slave station 2-1 corresponding to the identification number of the slave station 2 transmitted together with the abnormal state report request. It is the same as in the case of the first slave station 2-1 that it is possible to respond to this, and the operation sequence and contents of the response.
Also, the operation of the master station 1 that has received the response, that is, the abnormal state and type of the second line L2, is determined, and the determination result is input to the speech synthesizer 10, and the message voice signal corresponding thereto is used for operator instruction. The transmission to the transceiver 12 and the transmission to the operator's portable transceiver 3 are the same as in the case of the first slave station 2-1.
The worker W is notified by message voice of what kind of abnormal state has occurred on the second line L2 from the internal speaker of the portable transceiver 3 for the worker, and in the same manner as in the case of the first slave station 2-1. Take predetermined measures.

以下、同様にして、第3ラインL3から第5ラインL5についての異常状態とその種類が順次、作業者Wに通知され、第1ラインL1から第5ラインL5の全てについての異常状態への対処が行われる。作業者Wは、全ラインL1〜L5に対する位置や方向、更には遠近に拘わらず迅速、適確に通知を受けることができ、従来の「アンドン」を用いた表示による異常状態通知の遅れや不確実さを改善できる。
作業者指示用トランシーバ12からのメッセージ音声信号は受信先を特定しないで送信されるので、図示例のように、作業者携帯用トランシーバ3を複数台用意し、複数人に各1台の作業者携帯用トランシーバ3を携帯させて、異なる場所にいる複数人への同時通知が可能となる。これによれば、異常状態への対処が一層、迅速、確実に行うことができ、従来の「アンドン」を用いた表示による異常状態通知の遅れや不確実さを著しく改善できる。
Thereafter, similarly, the abnormal state and the type of the third line L3 to the fifth line L5 are sequentially notified to the worker W, and the abnormal state for all of the first line L1 to the fifth line L5 is dealt with. Is done. The operator W can be notified promptly and accurately regardless of the position and direction with respect to all the lines L1 to L5, as well as the distance, and there is a delay or inconvenience of the abnormal state notification due to the display using the conventional “ANDON”. Certainty can be improved.
Since the message voice signal from the worker instruction transceiver 12 is transmitted without specifying the recipient, a plurality of worker portable transceivers 3 are prepared as shown in the figure, and each worker has one worker. By carrying the portable transceiver 3, it is possible to simultaneously notify a plurality of people at different locations. According to this, it is possible to deal with the abnormal state more quickly and reliably, and it is possible to remarkably improve the delay and uncertainty of the abnormal state notification due to the display using the conventional “ANDON”.

以上述べたように本実施形態では、複数のラインL1〜L5の異常状態を通知するシステムを、親局1と、各ラインLに付設された子局2と、作業者携帯用トランシーバ3とを備え、これら相互間の通信を各々トランシーバ4,7を用いて無線で行うようにした。また、各子局2は、自局が付設されたラインLの異常状態をコード化したトーン信号を自局のトランシーバ7に入力させて親局1に送信可能とした。そして、親局1は各子局2との無線通信によって各ラインLの異常状態を収集し、得られた異常状態を、音声合成回路10によってメッセージ音声信号に変換して作業者指示用トランシーバ12に与え、作業者携帯用トランシーバ3に対して無線送信して通知するようにした。
したがって本実施形態によれば、作業者Wは、全ラインL1〜L5に対する位置や方向、更には遠近に拘わらず迅速、適確に通知を受けることができ、従来の「アンドン」を用いた表示による異常状態通知の遅れや不確実さを改善できる。
