Description

本発明は、工具用の無線通信装置、殊に無線通信周波数や送信出力などの無線通信パラメータの設定に関するものである。   The present invention relates to a wireless communication device for a tool, and more particularly to setting of wireless communication parameters such as a wireless communication frequency and a transmission output.

工具を用いたねじ締め作業を行う工場において、工具として締め付けトルクを制御することができるものを用いるとともに、所要トルクでの締め付けが完了したことを管理装置側に送信することでねじ締め作業を管理できるようにしたものがある。この場合、有線通信であると、工具の使い勝手に影響を及ぼすために、特許文献１及び特許文献２に示すように、無線通信を用いることが好ましい。   In factories that perform screw tightening work using tools, tools that can control the tightening torque are used as tools, and screw tightening work is managed by transmitting to the management device that tightening with the required torque has been completed. There is something that you can do. In this case, in the case of wired communication, in order to affect the usability of the tool, it is preferable to use wireless communication as shown in Patent Document 1 and Patent Document 2.

一方、工場内では無線ＬＡＮなどの環境ノイズが存在している可能性があり、無線通信の場合、このノイズによる通信ミスが生じる虞がある。しかし、従来のものは無線通信周波数が固定であり、現場での変更ができないために、無線通信周波数を変更することができるようにしておくことが求められている。   On the other hand, there may be an environmental noise such as a wireless LAN in the factory, and in the case of wireless communication, there is a possibility that a communication error due to this noise occurs. However, since the conventional wireless communication frequency is fixed and cannot be changed in the field, it is required to change the wireless communication frequency.

このために、無線通信周波数をＤＩＰスイッチによって設定変更することができるようにしたものが提案されている。しかし、工具側にＤＩＰスイッチ等の設定用スイッチを数多く設けることは、使用環境によっては鉄粉等のゴミの侵入が原因で工具動作不良を招く虞が高くなる。   For this reason, a wireless communication frequency that can be set and changed by a DIP switch has been proposed. However, providing a large number of setting switches such as DIP switches on the tool side increases the risk of tool operation failure due to intrusion of dust such as iron powder depending on the usage environment.

また、工具に複数の設定用スイッチを設ける必要性を無くすために、パーソナルコンピュータ（以下ＰＣと称す）に接続してＰＣによって無線通信周波数や送信先の受信機のＩＤナンバーを設定することができるようにしたものも提案されているが、現場においてＰＣに接続して設定変更を行うことは、複数の工具が使用されている工場においては、各工具を個別にＰＣと接続して工具の設定変更を行うことになり、非常に作業効率が悪い。   Further, in order to eliminate the necessity of providing a plurality of setting switches on the tool, it is possible to connect to a personal computer (hereinafter referred to as a PC) and set the wireless communication frequency and the ID number of the receiver at the transmission destination by the PC. However, in the factory where multiple tools are used, each tool is connected to the PC individually to set the tool. Changes will be made, and work efficiency will be very poor.

特許第２９８３１２４号公報Japanese Patent No. 2983124 特開２０００−０２４９４５号公報Japanese Unexamined Patent Publication No. 2000-024945

本発明は上記の点に鑑みなされたものであって、無線通信周波数等の無線通信パラメータの設定を簡便に変更することができる工具用無線通信システムを提供することを課題とするものである。   This invention is made in view of said point, Comprising: It aims at providing the radio | wireless communications system for tools which can change the setting of radio | wireless communication parameters, such as a radio | wireless communication frequency, simply.

本発明は、 無線通信手段を備えた工具と、工具の無線通信手段から無線送信された信号を受ける無線通信手段を備えた受信機とからなり、両無線通信手段間の無線通信のための無線通信パラメータの設定部を工具が備えているとともに該設定部は工具用リモートコントローラとして設けられており、受信機は工具側の上記設定部で設定されて受信機側に無線通信で伝達される無線通信パラメータを無線通信手段にセットする受信機制御手段を備えていることに特徴を有している。   The present invention comprises a tool including wireless communication means and a receiver including wireless communication means for receiving a signal wirelessly transmitted from the wireless communication means of the tool, and wireless communication for wireless communication between the two wireless communication means. The tool is provided with a communication parameter setting unit, and the setting unit is provided as a tool remote controller. The receiver is set by the setting unit on the tool side and transmitted to the receiver side by wireless communication. It is characterized by having receiver control means for setting communication parameters in the wireless communication means.

無線通信パラメータの設定部を工具用のリモートコントローラに設けて、この設定部で設定された無線通信パラメータが無線通信によって受信機側にもセットされるために、簡便に設定することができる上に工具の使用環境に設定部が影響を受けてしまうことがないものである。   A wireless communication parameter setting unit is provided in the tool remote controller, and the wireless communication parameters set in this setting unit are also set on the receiver side by wireless communication. The setting unit is not affected by the usage environment of the tool.

この時、無線通信パラメータの伝達用に専用周波数を用いるものであると、同様のシステムが混在しても作業時に混信してしまうことを無くすことができる。   At this time, if a dedicated frequency is used for transmission of wireless communication parameters, it is possible to eliminate interference during work even if similar systems are mixed.

また、無線通信パラメータの伝達を通常通信時よりも低い送信出力で行うものである場合、同周波数を使用する他のシステムの干渉を抑えることができて、他のシステムに悪影響を与えてしまうことを避けることができる。   In addition, when wireless communication parameters are transmitted at a lower transmission output than during normal communication, interference from other systems that use the same frequency can be suppressed, adversely affecting other systems. Can be avoided.

前記無線パラメータ設定手段は再送回数を設定する再送回数設定部を備えたものとするのが好ましい。作業に応じて適切な再送回数を設定することができる。   The radio parameter setting means preferably includes a retransmission number setting unit for setting the number of retransmissions. An appropriate number of retransmissions can be set according to work.

そして前記受信機が個別の識別ナンバーを有する複数の工具と通信するものであると、受信機１台で複数の工具を管理することができて、受信機設置台数及び受信機設置スペースを削減することができ、コストダウンを図ることができる。   If the receiver communicates with a plurality of tools having individual identification numbers, a single receiver can manage the plurality of tools, and the number of receivers installed and the receiver installation space can be reduced. Cost reduction.

本発明においては、工具用のリモートコントローラに設けた無線通信パラメータの設定部で設定された無線通信パラメータが無線通信によって受信機側にもセットされるために、受信機側への無線通信パラメータのセットを簡便に行うことができるものであり、しかもリモートコントローラは工具とは異なって良好な環境の下に置くことができるために、上記設定部が工具振動や粉塵等の影響で設定不良を招く虞を避けることができる。   In the present invention, since the wireless communication parameter set by the wireless communication parameter setting unit provided in the remote controller for the tool is also set on the receiver side by wireless communication, the wireless communication parameter to the receiver side is set. Since the set can be performed easily and the remote controller can be placed in a favorable environment unlike a tool, the setting section causes a setting failure due to the influence of tool vibration, dust, etc. Fear can be avoided.

本発明を実施の形態の一例に基づいて詳述すると、図示例は工具１として電動インパクトドライバを示している。このインパクトドライバは、図３及び図４に示すように、回転動力源としてのモータ１０と、ハンマとアンビルとからなる打撃機構を有してモータ１０の回転出力を回転打撃として出力軸１２に出力する締付機構手段１１と、締付機構手段１１によるねじ締め作業の状態を検出する作業状態検出手段１３とを備えるとともに、上記モータ１０の動作をモータ制御手段１４を介して制御する工具制御手段１５と、無線通信手段１６とを備えたものであるとともに、リモートコントローラ３を備えたもので、着脱自在な電池パック１８内の二次電池を電源として作動する。図３中の１９はモータ１０のオンオフ及びその操作量でモータ印加電圧を変化させてモータの回転数を調整するトリガースイッチである。   The present invention will be described in detail based on an example of the embodiment. The illustrated example shows an electric impact driver as the tool 1. As shown in FIGS. 3 and 4, this impact driver has a motor 10 as a rotational power source and an impact mechanism composed of a hammer and an anvil, and outputs the rotational output of the motor 10 to the output shaft 12 as a rotational impact. And a tool control means for controlling the operation of the motor 10 via the motor control means 14. The tool control means 14 controls the operation of the motor 10 via the motor control means 14. 15 and the wireless communication means 16, as well as the remote controller 3, which operates using a secondary battery in the detachable battery pack 18 as a power source. Reference numeral 19 in FIG. 3 denotes a trigger switch that adjusts the rotational speed of the motor by changing the motor applied voltage according to the on / off of the motor 10 and its operation amount.

上記無線通信手段１６は、送信周波数及び送信出力を共に変更することができるもので、送受信を行う無線制御手段３１と、送信出力を変更するための送信出力設定手段３２と、送信周波数を変更するための送信周波数設定手段３３とからなる。   The wireless communication means 16 can change both the transmission frequency and the transmission output. The wireless control means 31 performs transmission / reception, the transmission output setting means 32 changes the transmission output, and changes the transmission frequency. Transmission frequency setting means 33.

上記作業状態検出手殺１３は、ハンマがアンビルに衝突する打撃を検出してこの打撃数をカウントすることで締め付けトルクを検出するものであり、工具制御手段１５はねじ締めが完了したと判断した時、モータ１０を停止させるとともに、無線通信手段１６を通じて外部に作業完了信号を出力する。なお、作業状態検出手段１３は、出力軸１２の回転角量を検出するものや、トルクセンサで構成されたものであってもよい。   The above-mentioned work state detection manual killing 13 detects the tightening torque by detecting the hammer hitting the anvil and counting the number of hits, and the tool control means 15 determines that the screw tightening has been completed. At the same time, the motor 10 is stopped and a work completion signal is output to the outside through the wireless communication means 16. The work state detection means 13 may be one that detects the amount of rotation angle of the output shaft 12 or one that is constituted by a torque sensor.

上記無線通信手段１６から送出される作業完了信号は、図１及び図２に示すように、作業完了識別データと、送信元である工具に付されている工具ＩＤナンバーと、送信先である受信機２に付されている受信機ＩＤナンバーを含む信号である。なお、工具ＩＤナンバーは、電動工具の工場出荷時に付された各工具固有のもので上記工具制御手段１５内の不揮発性メモリに書き込まれたものであり、受信機ＩＤナンバーは後述する登録モード時に上記不揮発性メモリに書き込まれるものである。   As shown in FIG. 1 and FIG. 2, the work completion signal transmitted from the wireless communication means 16 includes work completion identification data, a tool ID number assigned to a tool as a transmission source, and reception as a transmission destination. This signal includes the receiver ID number assigned to the machine 2. The tool ID number is unique to each tool attached at the time of factory shipment of the electric tool, and is written in the nonvolatile memory in the tool control means 15, and the receiver ID number is in the registration mode described later. It is written in the non-volatile memory.

工具１に付属するリモートコントローラ３は、工具制御手段１５との間で例えば赤外線通信によって信号の送受を行うワイヤレスタイプのもので、無線通信パラメータの設定部３０を備えている。設定される無線通信パラメータの一例を図５に示す。ここでは使用周波数と送信出力と再送回数を無線通信パラメータとしている。   The remote controller 3 attached to the tool 1 is a wireless type that transmits and receives signals to and from the tool control means 15 by infrared communication, for example, and includes a wireless communication parameter setting unit 30. An example of the set wireless communication parameters is shown in FIG. Here, the used frequency, transmission output, and number of retransmissions are used as wireless communication parameters.

一方、ねじ締め作業の管理を行う管理装置側にあって上記無線通信手段１６から送出された作業完了信号を受信する受信機２は、図４に示すように、モード設定手段２３が接続された受信機制御手段手段２１と、無線通信手段２４とからなり、無線通信手段２４は、上記の工具１側の無線通信手段１６と同様に送信周波数及び送信出力を共に変更することができるもので、送受信を行う無線制御手段２５と、送信出力を変更するための送信出力設定手段２６と、送信周波数を変更するための送信周波数設定手段２７とからなる。   On the other hand, the receiver 2 that receives the work completion signal sent from the wireless communication means 16 on the management apparatus side that manages the screw tightening work is connected to the mode setting means 23 as shown in FIG. It consists of a receiver control means means 21 and a wireless communication means 24. The wireless communication means 24 can change both the transmission frequency and the transmission output in the same manner as the wireless communication means 16 on the tool 1 side. A radio control means 25 for performing transmission / reception, a transmission output setting means 26 for changing the transmission output, and a transmission frequency setting means 27 for changing the transmission frequency.

ここにおいて、工具１側のモード設定手段１７及び受信機２側のモード設定手段２３は、通常の通信モードと、登録作業を行うための登録モードとの切り換えのためのものであり、上記両無線通信手段１６，２４間の無線通信のための無線通信パラメータは、登録モード時に設定される。   Here, the mode setting means 17 on the tool 1 side and the mode setting means 23 on the receiver 2 side are for switching between the normal communication mode and the registration mode for performing the registration work. Wireless communication parameters for wireless communication between the communication means 16 and 24 are set in the registration mode.

まず、通常の通信モード時の動作について図１及び図２に基づいて説明すると、工具１の電源がオンされた場合、工具制御手段１５内の不揮発性メモリから出荷時に記憶されている工具ＩＤナンバー、過去の登録により記憶されている受信機ＩＤナンバー、送信使用周波数（作業完了信号を送信する時に使用する周波数）、信号送信出力（作業完了信号を送信する時の送信出力値）、再送回数（作業完了信号を受信機に送信する回数）を読み出して送信使用周波数と信号送信出力とを無線制御手段２５に伝達する。無線制御手段２５はこの設定値に応じて送信出力設定手段２６で送信出力を、送信周波数設定手段２７で送信周波数を設定する。   First, the operation in the normal communication mode will be described with reference to FIG. 1 and FIG. 2. When the power of the tool 1 is turned on, the tool ID number stored at the time of shipment from the nonvolatile memory in the tool control means 15. , Receiver ID number stored by past registration, transmission use frequency (frequency used when transmitting work completion signal), signal transmission output (transmission output value when transmitting work completion signal), number of retransmissions ( The number of times when the work completion signal is transmitted to the receiver is read out, and the transmission use frequency and the signal transmission output are transmitted to the wireless control means 25. The radio control unit 25 sets the transmission output by the transmission output setting unit 26 and the transmission frequency by the transmission frequency setting unit 27 according to the set value.

そしてリモートコントローラ３による操作で登録モードになっていない場合、工具制御手段１５はトリガスイッチがオンされるとモータ１０を駆動し、作業状態検出手段１３による作業完了判定を検出すればモータ１０を停止し、前述のように作業完了信号を無線通信手段１６から送出する。   When the registration mode is not operated by the operation of the remote controller 3, the tool control means 15 drives the motor 10 when the trigger switch is turned on, and stops the motor 10 when the work completion detection means 13 detects the work completion determination. Then, the work completion signal is sent from the wireless communication means 16 as described above.

受信機２においては、受信した作業完了信号に含まれる受信機ＩＤナンバーが自己に付されているＩＤナンバーと一致するかどうか、作業完了信号中の工具ＩＤナンバーが予め登録されている管理すべき工具ＩＤナンバーと一致するかどうかを判定し、一致する場合は受信完了識別データと、送信元である受信機２に付されている受信機ＩＤナンバーと、送信先である工具ＩＤナンバーとを含む受信完了信号を無線通信手段２４から送出するともに、受信完了信号送信後、管理装置本体側に対して受信完了出力を出力する。   In the receiver 2, whether or not the receiver ID number included in the received work completion signal matches the ID number assigned to the receiver 2, the tool ID number in the work completion signal should be registered in advance. It is determined whether or not it matches the tool ID number. If they match, the reception completion identification data, the receiver ID number assigned to the receiver 2 as the transmission source, and the tool ID number as the transmission destination are included. A reception completion signal is transmitted from the wireless communication means 24, and after the reception completion signal is transmitted, a reception completion output is output to the management apparatus main body side.

上記受信完了信号を受信した工具制御手段１５は、受信機ＩＤナンバーと工具ＩＤナンバーとが不揮発メモリに書き込まれているものと一致する時、送信完了と判断し、トリガースイッチ１９がオフとなった時点で初期状態に戻る。   The tool control means 15 that has received the reception completion signal determines that transmission is complete when the receiver ID number and the tool ID number match those written in the nonvolatile memory, and the trigger switch 19 is turned off. Return to the initial state at that point.

なお、ＩＤナンバーが一致しない場合は、設定されている再送回数だけ再送を繰り返すものとしてある。再送回数が無限回の場合は送信完了まで上記処理を繰り返すものとする。再送回数を再送繰返し時間として設定できるようにしても良い。工場等の工程における作業は様々であり、作業間隔も様々である。従って無線通信が成功するまで再送するシステムが要求される場合は再送回数を無限回数、そうでない場合は各作業間隔にあった再送回数を設定することで、各作業における無線通信成功率を最大限に向上させることができる。   When the ID numbers do not match, the retransmission is repeated for the set number of retransmissions. When the number of retransmissions is infinite, the above process is repeated until the transmission is completed. The number of retransmissions may be set as the retransmission repetition time. There are various operations in the process of factories and the like, and the operation intervals are also various. Therefore, if a system that retransmits until wireless communication is successful is requested, the number of retransmissions is set to infinite. Otherwise, the number of retransmissions set for each work interval is set to maximize the wireless communication success rate in each work. Can be improved.

次にリモートコントローラ３を用いた無線通信パラメータの設定変更について説明すると、予めリモートコントローラ３において無線通信パラメータ（周波数と出力と再送回数）の設定を行っておき、リモートコントローラ３に設けた設定スイッチをオンとすれば、この設定信号を受けた工具制御手段１５は、使用周波数設定を登録専用の周波数ＣＨ０に、送信出力を０（最小出力）に切り換える。受信機２側においてもモード設定手段２３によって登録モードに切り換えれば、使用周波数設定を登録専用の周波数ＣＨ０に、送信出力を０（最小出力）に切り換える。作業完了通知用の周波数とは異なる登録専用の周波数を用いるのは、同様のシステムが作業時に混信しないようにするためであり、送信出力設定を０にするのは、同周波数帯を使用する他のシステムへの干渉を抑えて、他のシステムへ悪影響が発生しないようにするためである。   Next, the setting change of the wireless communication parameter using the remote controller 3 will be described. The wireless communication parameter (frequency, output, and number of retransmissions) is set in the remote controller 3 in advance, and the setting switch provided in the remote controller 3 is set. When turned on, the tool control means 15 that has received this setting signal switches the use frequency setting to the registration-dedicated frequency CH0 and the transmission output to 0 (minimum output). On the receiver 2 side, if the mode setting means 23 switches to the registration mode, the use frequency setting is switched to the registration-dedicated frequency CH0, and the transmission output is switched to 0 (minimum output). The frequency dedicated for registration, which is different from the frequency for notification of work completion, is used to prevent similar systems from interfering during work, and the transmission output setting is set to 0 in addition to using the same frequency band. This is to prevent interference with other systems and prevent other systems from being adversely affected.

次いでリモートコントローラ３における登録スイッチをオンとすれば、工具制御手段１５は登録モードに移行し、登録要求識別データと送信元としての自身の工具ＩＤナンバーと、リモートコントローラ３において設定された無線通信パラメータとを含む登録要求信号を送出する。   Next, when the registration switch in the remote controller 3 is turned on, the tool control means 15 shifts to the registration mode, the registration request identification data, its own tool ID number as the transmission source, and the wireless communication parameter set in the remote controller 3. A registration request signal including

この登録要求信号を受けた受信機制御手段２１は、登録完了識別データと送信元を示す受信機ＩＤナンバーと送信先を示す工具ＩＤナンバーとを含む登録完了信号を送信するとともに、登録要求信号に含まれていた無線通信パラメータ、つまりは作業完了信号用使用周波数、作業完了信号用送信出力、再送回数を受信機制御手段２１が備える不揮発性メモリに工具ＩＤナンバーと前記無線通信パラメータとを記憶する。   Receiving this registration request signal, the receiver control means 21 transmits a registration completion signal including registration completion identification data, a receiver ID number indicating the transmission source, and a tool ID number indicating the transmission destination, and also includes a registration request signal. The tool ID number and the wireless communication parameter are stored in the nonvolatile memory provided in the receiver control means 21 with the included wireless communication parameters, that is, the work completion signal use frequency, the work completion signal transmission output, and the number of retransmissions. .

受信機２から送出された登録完了信号を受信した工具制御手段１５は、ＩＤナンバーが一致した時、工具制御手段１５内の不揮発性メモリに前記通信に関するパラメータと受信機ＩＤナンバーとを記憶する。各ＩＤナンバーが一致しない場合は登録要求信号を再送し、上記処理を繰り返す。   The tool control means 15 that has received the registration completion signal sent from the receiver 2 stores the parameters related to the communication and the receiver ID number in the nonvolatile memory in the tool control means 15 when the ID numbers match. If the ID numbers do not match, the registration request signal is retransmitted and the above process is repeated.

従って、工具１及び受信機２を登録モードから通常の通信モードに戻せば、両者間の無線通信は各制御手段１５，２１の不揮発性メモリに新たに書き込まれた無線通信パラメータで行われることになる。   Therefore, if the tool 1 and the receiver 2 are returned from the registration mode to the normal communication mode, the wireless communication between them is performed with the wireless communication parameters newly written in the nonvolatile memory of the control means 15 and 21. Become.

ここでは工具１と受信機２とが１対１である場合の説明をしたが、受信機２側で登録操作を繰り替えすことにより、異なる工具ＩＤナンバーを有する複数の複数の工具１を単一の受信機２に登録するとともに無線通信パラメータを設定することで、複数の工具を受信機１台で認識可能にすることができ、この場合、工場工程内の受信機２数を減らして受信機配置スペース、コスト等を低減することができる。   Here, the case where the tool 1 and the receiver 2 are one-to-one has been described. However, by repeating the registration operation on the receiver 2 side, a plurality of tools 1 having different tool ID numbers can be used as a single unit. It is possible to recognize a plurality of tools by one receiver by registering with the receiver 2 and setting wireless communication parameters. In this case, the number of receivers 2 in the factory process is reduced and the receiver Arrangement space, cost, etc. can be reduced.

なお、工具１側にモード設定手段１７を設けて、設定モード及び登録モードにはリモートコントローラ３の操作で移行するのではなく、モード設定手段１７によって移行するものとしてもよい。   Note that the mode setting means 17 may be provided on the tool 1 side, and the mode setting means 17 may be used instead of shifting to the setting mode and the registration mode by operating the remote controller 3.
