The present invention relates to a wireless communication method that can be used.

締付機等の回転軸に取り付けられる締付トルク測定ユニットに情報の送信可能な端末機器を内蔵し、無線によりダイレクトにトルク値や回転角度等のデータを情報として、受信側となる中央装置に送信することのできる送受信システムを出願人は提案している(例えば、特許文献１参照)。   A terminal device capable of transmitting information is built into the tightening torque measuring unit attached to the rotating shaft of a tightening machine, etc., and the data such as torque value and rotation angle is directly transmitted as information to the central device on the receiving side. The applicant has proposed a transmission / reception system capable of transmitting (see, for example, Patent Document 1).

上記送受信システムでは、端末機器は電池を電源とし、中央装置は商用電源を利用している。
測定を開始して情報を送受信させる前には、端末機器及び中央装置の夫々の電源をオン状態にした後、端末機器を消費電力が大きい受信可能状態として、接続を確立させる必要がある。また、測定作業終了後、端末機器及び中央装置の夫々の電源をオフにする必要がある。 In the transmission / reception system, the terminal device uses a battery as a power source, and the central apparatus uses a commercial power source.

特願２００９−９９７６４号Japanese Patent Application No. 2009-99764

端末機器と中央装置の電源を夫々オンにするには、ユーザには手間が掛かる行為である。
また、ユーザに対しての利便性の為、中央装置で電源オンされると同時に自動的に端末機器の電源もオンとなるようなシステムとするために、端末機器をたえず受信可能状態で待機させた場合、電池の消耗が激しくなる。
さらに、測定作業終了後、端末機器及び中央装置の夫々の電源をオフにする必要があるが、端末機器の電源を切り忘れると、電池寿命が短命化する。 In order to turn on the power of the terminal device and the central device, it is an action that takes time for the user.
In addition, for the convenience of the user, the terminal device is always kept in a standby state so that the terminal device is automatically turned on at the same time as the power is turned on at the central device. If this happens, the battery will become exhausted.
Furthermore, it is necessary to turn off the power of the terminal device and the central device after the measurement work is completed. If the power of the terminal device is forgotten to be turned off, the battery life is shortened.

本発明の目的は、電池を電源とする端末機器と、商用電源を用いる中央装置との間の無線通信に際し、端末機器の電源オン、オフ操作を不要としつつ、端末機器の電池の消耗を低減させることのできる無線通信方法を提供することである。   An object of the present invention is to reduce the battery consumption of a terminal device while eliminating the need to turn the terminal device on and off during wireless communication between the terminal device using a battery as a power source and a central device using a commercial power source. It is to provide a wireless communication method that can be performed.

端末機器で、中央装置からの接続要求確認を所定時間毎に行なう待機シーケンスと、
中央装置に電源が投入された後、中央装置から端末機器へ接続要求送信を連続して行なう接続確立シーケンスと、
端末機器と中央装置との間で接続が確立された後、端末機器と中央装置との間で情報の送受信を行なう送受信シーケンスと、
を有する。 In order to solve the above problems, a wireless communication method between the terminal device of the present invention and the central device is:
A terminal device that can send and receive information using a battery as a power source;
A wireless communication method using a commercial power source as a power source and a central device capable of transmitting and receiving information to and from the terminal device,
In the terminal device, a standby sequence for performing a connection request confirmation from the central device every predetermined time, and
A connection establishment sequence for continuously sending connection requests from the central device to the terminal device after the central device is powered on,
After the connection is established between the terminal device and the central device, a transmission / reception sequence for transmitting / receiving information between the terminal device and the central device,
Have

なお、上記待機シーケンスでは、端末機器で、中央装置への接続要求送信を所定時間毎に行ない、接続確立シーケンスでは、中央装置に電源が投入された後、中央装置で端末機器からの接続要求確認を連続して行なうようにしてもよい。   In the standby sequence, the terminal device transmits a connection request to the central device every predetermined time. In the connection establishment sequence, after the central device is turned on, the central device confirms the connection request from the terminal device. May be performed continuously.

端末機器は、受信可能状態を維持するのではなく、所定時間毎に接続要求確認又は接続要求送信を行ない(待機シーケンス)、中央装置との接続が確立された場合にのみ(接続確立シーケンス)、端末機器と中央装置との間で情報の送受信を行なうようにすることで(送受信シーケンス)、電池の消費を低減することができ、電池の長寿命化を達成できる。
また、上記により、端末機器の電源を投入する手間を省くことができる。
さらに、中央装置の電源が切断、又は、中央装置との接続が切断されると、再度、待機シーケンスに戻すシーケンスを追加すると、端末機器の電池の消費を低減できる。
同様に、端末機器は、使用者が自ら電源をオフにする手間を省くことができる。 The terminal device does not maintain a receivable state, but performs connection request confirmation or connection request transmission at a predetermined time (standby sequence), only when a connection with the central device is established (connection establishment sequence), By transmitting and receiving information between the terminal device and the central device (transmission / reception sequence), it is possible to reduce battery consumption and to extend the battery life.
In addition, the trouble of turning on the terminal device can be saved by the above.
Further, when the power supply of the central device is cut off or the connection with the central device is cut off, the battery consumption of the terminal device can be reduced by adding a sequence for returning to the standby sequence again.
Similarly, the terminal device can save the user from having to turn off the power.

端末機器Ａ(20)は、電池を電源として作動する機器であり、締付機(60)の回転軸に取付可能な締付トルク測定ユニットから締付トルクや回転角度等に関する情報を端末機器Ａ(20)から中央装置へ送信可能となっている。 <Connection establishment sequence with terminal device A>
The terminal device A (20) is a device that operates using a battery as a power source. Information on the tightening torque, rotation angle, and the like is received from the tightening torque measuring unit that can be attached to the rotating shaft of the tightening machine (60). (20) can be transmitted to the central device.

中央装置(10)は、商用電源にて作動し、公知の要領にて、締付機(60)の種々の制御を行なうと共に、各端末機器(20)(30)(40)と無線通信を行なう。なお、中央装置(10)には、測定データの単位を変更可能な単位変更ボタン(12)(後述する)を有する。   The central device (10) operates with a commercial power source, performs various controls of the tightening machine (60) and performs wireless communication with each terminal device (20) (30) (40) in a known manner.

端末機器Ａ(20)は、締付が完了し、締付トルク測定ユニットが測定値を確定する(例えば、ピークトルクを検出する)まで、測定値の送信を続け、測定値が確定すると、確定送信値を送信し(Ａ２５)、中央装置(10)から端末機器Ａ(20)へＡｃｋ信号(肯定応答信号)を送信して(Ｓ２４)、端末機器Ａ(20)がＡｃｋ信号を受信することで(Ａ２６)、一回の測定値送受信シーケンスが完了する。   The terminal device A (20) continues to transmit the measured value until the tightening is completed and the tightening torque measurement unit confirms the measured value (for example, detects peak torque). The transmission value is transmitted (A25), the Ack signal (acknowledgment signal) is transmitted from the central device (10) to the terminal device A (20) (S24), and the terminal device A (20) receives the Ack signal. (A26), one measurement value transmission / reception sequence is completed.

＜端末機器Ｂとの測定値送受信シーケンス＞
端末機器Ｂ(30)は、中央装置(10)との接続が確立された後、中央装置(10)の運転状況を確認する為に、所定時間(例えば５秒)毎にＰｉｎｇ信号を送信し(Ｂ２０)、中央装置(10)は、Ｐｉｎｇ信号を受信すると(Ｓ２５)、Ｐｉｎｇ信号を返信して(Ｓ２６)、両者の接続を確認しておく。
端末機器Ｂ(30)は、Ｐｉｎｇ返信を受信するまでの間のみ、受信可能状態としておくことが望ましく、これにより電池の消耗を低減させることができる。 <Measurement Value Transmission / Reception Sequence with Terminal Device B>
After the connection with the central device (10) is established, the terminal device B (30) transmits a Ping signal every predetermined time (for example, 5 seconds) in order to check the operation status of the central device (10). (B20) Upon receiving the Ping signal (S25), the central device (10) returns the Ping signal (S26) and confirms the connection between the two.
It is desirable that the terminal device B (30) be in a receivable state only until a Ping reply is received, thereby reducing battery consumption.

中央装置(10)が、端末機器Ａ(20)から測定値を受信すると(Ｓ２０)、中央装置(10)は、受信したＰｉｎｇ信号に対する返信信号に、端末機器Ｂ(30)への受信待機依頼の信号を含めて送信する(Ｓ２７)。
この信号を受信すると(Ｂ２１)、端末機器Ｂ(30)は、Ｐｉｎｇ通信を中断し、中央装置(10)からの受信待機状態終了（Ｓ２９）の信号を受信するまでの間のみ受信可能状態とする(Ｂ２２)。これにより、端末機器Ｂ(30)の電池の消耗を低減させることができる。
次に、中央装置(10)は、端末機器Ａ(20)から受信した測定値を端末機器Ｂ(30)に表示値信号として送信する(Ｓ２８)。端末機器Ｂ(30)は、受信した表示値信号を順次表示部(31)に表示する(Ｂ２３)。 When the central device (10) receives the measurement value from the terminal device A (20) (S20), the central device (10) sends a reception waiting request to the terminal device B (30) as a reply signal to the received Ping signal. (S27).
When this signal is received (B21), the terminal device B (30) interrupts the Ping communication and is in a receivable state only until a signal indicating that the reception standby state has ended (S29) is received from the central device (10). (B22). Thereby, battery consumption of the terminal device B (30) can be reduced.
Next, the central apparatus (10) transmits the measurement value received from the terminal device A (20) to the terminal device B (30) as a display value signal (S28). The terminal device B (30) sequentially displays the received display value signal on the display unit (31) (B23).

なお、中央装置(10)は、端末機器Ａ(20)から受信した複数の測定値信号からその最大値等のみ取り出して、端末機器Ａ(20)からの送信値受信間隔(本実施例の場合１０ｍｓ)よりも間隔を広げて(例えば５００ｍｓ)送信するようにし、端末機器Ｂ(30)の表示部(31)に表示される表示値の更新間隔が長くなるようにすることが望ましい。これにより、端末機器Ｂ(30)の送受信間隔を広げることができるから、端末機器Ｂ(30)の電池消耗を低減でき、また、中央装置(10)の動作負荷が減少する。   The central device (10) extracts only the maximum value from the plurality of measurement value signals received from the terminal device A (20), and transmits the transmission value reception interval from the terminal device A (20) (in this embodiment). It is desirable that transmission be performed with a longer interval (for example, 500 ms) than 10 ms) so that the display value update interval displayed on the display unit (31) of the terminal device B (30) is longer. Thereby, since the transmission / reception interval of the terminal device B (30) can be widened, the battery consumption of the terminal device B (30) can be reduced, and the operation load of the central device (10) is reduced.

中央装置(10)は、端末機器Ａ(20)から確定送信値を受信し、Ａｃｋ信号を返信すると(Ｓ２４)、表示値が確定したことを示す確定表示値信号を端末機器Ｂ(30)に送信し(Ｓ２９)、端末機器Ｂ(30)は、該信号を受信すると、送受信状態として、Ａｃｋ信号を中央装置(10)へ送信する(Ｂ２４)。   When the central device (10) receives the final transmission value from the terminal device A (20) and returns an Ack signal (S24), the central device (10) sends a final display value signal indicating that the display value has been finalized to the terminal device B (30). The terminal device B (30) receives the signal and transmits the Ack signal to the central device (10) as a transmission / reception state (B24).

その後、中央装置(10)は、端末機器Ａ(20)から受信した測定値を端末機器Ｃ(40)に表示値信号として送信する(Ｓ３０)。 <Measurement Value Transmission / Reception Sequence with Terminal Device C>
Since the terminal device C (40) uses a commercial power supply, the terminal device C (40) shifts to a constantly receivable state after the connection with the central device (10) is established.
Thereafter, the central device (10) transmits the measurement value received from the terminal device A (20) to the terminal device C (40) as a display value signal (S30).

なお、中央装置(10)は、前記端末機器Ｂ(30)の場合と同様に、端末機器Ａ(20)から受信した複数の測定値信号からその最大値等のみ取り出して、端末機器Ａ(20)からの送信値受信間隔(本実施例の場合１０ｍｓ)よりも間隔をあけて(例えば５００ｍｓ)送信するようにし、端末機器Ｃ(40)の表示部(41)に表示される表示値の更新間隔が長くなるようにすることが望ましい。これにより、端末機器Ｃ(40)における同じ表示値の更新期間を長くすることができ、中央装置(10)の動作負荷が減少する。   As in the case of the terminal device B (30), the central device (10) extracts only the maximum value from the plurality of measurement value signals received from the terminal device A (20) and obtains the terminal device A (20 ) From the transmission value reception interval (in this example, 10 ms) (for example, 500 ms), and the display value displayed on the display unit (41) of the terminal device C (40) is updated. It is desirable to increase the interval. Thereby, the update period of the same display value in the terminal device C (40) can be lengthened, and the operation load of the central device (10) is reduced.

中央装置(10)は、端末機器Ａ(20)から確定送信値を受信し、Ａｃｋ信号を返信すると、表示値が確定したことを示す確定表示値信号を端末機器Ｃ(40)に送信し(Ｓ３１)、端末機器Ｃ(40)は、該信号を受信すると、Ａｃｋ信号を中央装置(10)へ送信する(Ｃ２１)。   When the central device (10) receives the final transmission value from the terminal device A (20) and returns an Ack signal, the central device (10) transmits a final display value signal indicating that the display value is finalized to the terminal device C (40) ( When the terminal device C (40) receives the signal, the terminal device C (40) transmits an Ack signal to the central device (10) (C21).
