　まず、実施の形態１に係る通信システム１の構成を説明する。図１は、実施の形態１に係る通信システム１の構成を示す図である。通信システム１は、信号を送信する送信装置１０と、送信装置１０から送信された信号を受信する受信装置２０と、受信装置２０の位置を変更する機能を有する位置変更機構３０と、受信装置２０を回動させる機能を有する回動機構４０とを有する。受信装置２０は、電化製品に搭載されている。電化製品の例は、空気調和機である。図１における矢印は、送信装置１０から受信装置２０に送信される信号を示している。 Embodiment 1
First, the configuration of the communication system 1 according to Embodiment 1 will be described. FIG. 1 is a diagram showing the configuration of the communication system 1 according to the first embodiment. The communication system 1 includes a transmitting device 10 for transmitting a signal, a receiving device 20 for receiving a signal transmitted from the transmitting device 10, a position changing mechanism 30 having a function of changing the position of the receiving device 20, and a receiving device 20. And a pivoting mechanism 40 having a function of pivoting. The receiving device 20 is mounted on an electric appliance. An example of an appliance is an air conditioner. Arrows in FIG. 1 indicate signals transmitted from the transmitter 10 to the receiver 20.
　送信装置１０は、送信装置１０が受信装置２０に送信する信号のもとになる操作がユーザによって行われる操作部１１を有する。操作部１１の例は、タッチパネル又はボタンである。送信装置１０は、操作部１１に対して行われたユーザの操作を検出する検出部１２と、検出部１２によって検出されたユーザの操作の内容を判断する処理部１３とを更に有する。 The transmission device 10 includes an operation unit 11 by which a user performs an operation that is a source of a signal that the transmission device 10 transmits to the reception device 20. An example of the operation unit 11 is a touch panel or a button. The transmission device 10 further includes a detection unit 12 that detects a user operation performed on the operation unit 11 and a processing unit 13 that determines the content of the user operation detected by the detection unit 12.
　例えば、処理部１３は、ユーザの操作が通信調整モードを設定する操作であるか否かを判断する。通信調整モードは、送信装置１０が通信状態識別用信号をあらかじめ決められた第１の時間送信し続けるモードである。通信状態識別用信号は、送信装置１０と受信装置２０との通信の状態を識別するために用いられる信号である。送信装置１０は、通信調整モードを有する。 For example, the processing unit 13 determines whether the user's operation is an operation to set the communication adjustment mode. The communication adjustment mode is a mode in which the transmission device 10 continues to transmit the communication state identification signal for a predetermined first time. The communication state identification signal is a signal used to identify the state of communication between the transmission device 10 and the reception device 20. The transmitter 10 has a communication adjustment mode.
　送信装置１０は、処理部１３によって行われた判断の結果に対応する信号を生成する信号生成部１４を更に有する。上述の通り、受信装置２０は、電化製品に搭載されている。信号生成部１４が生成する信号の例は、受信装置２０が搭載されている電化製品を遠隔操作するためのリモートコントロールデータ信号である。信号生成部１４は、通信調整モードが送信装置１０に設定された場合、通信状態識別用信号を生成する。実施の形態１では、検出部１２、処理部１３及び信号生成部１４は、マイクロコンピュータによって実現されている。 The transmitting device 10 further includes a signal generating unit 14 that generates a signal corresponding to the result of the determination made by the processing unit 13. As described above, the receiving device 20 is mounted on an electric appliance. An example of the signal generated by the signal generation unit 14 is a remote control data signal for remotely operating the electric appliance in which the receiving device 20 is mounted. When the communication adjustment mode is set to the transmission device 10, the signal generation unit 14 generates a communication state identification signal. In the first embodiment, the detection unit 12, the processing unit 13, and the signal generation unit 14 are realized by a microcomputer.
　送信装置１０は、信号生成部１４によって生成された信号を赤外線に変換し、変換された信号を受信装置２０に送信する送信部１５を更に有する。送信部１５の例は、赤外線発光ダイオードである。例えば、送信部１５は、リモートコントロールデータ信号を送信した後に通信状態識別用信号を送信する。つまり、例えば、送信装置１０は、リモートコントロールデータ信号を送信した後に通信状態識別用信号を送信する。 The transmitter 10 further includes a transmitter 15 that converts the signal generated by the signal generator 14 into infrared light and transmits the converted signal to the receiver 20. An example of the transmitter 15 is an infrared light emitting diode. For example, the transmission unit 15 transmits a communication state identification signal after transmitting the remote control data signal.

The receiving device 20 further includes an arithmetic processing unit 23 that executes processing of the content indicated by the signal received by the receiving unit 21.
　演算処理部２３は、受信部２１によって受信された信号がリモートコントロールデータ信号である場合、リモートコントロールデータ信号の内容の動作を受信装置２０が搭載されている電化製品に行わせるための処理を実行する。演算処理部２３は、情報を記憶する機能を有する。つまり、演算処理部２３は、記憶部を有する。例えば、記憶部は半導体メモリである。 When the signal received by the receiving unit 21 is a remote control data signal, the arithmetic processing unit 23 executes a process for causing the electric device on which the receiving device 20 is mounted to perform an operation of the content of the remote control data signal. Do. The arithmetic processing unit 23 has a function of storing information. That is, the arithmetic processing unit 23 has a storage unit. For example, the storage unit is a semiconductor memory.
　受信装置２０は、受信部２１によって受信された信号の受信状態があらかじめ決められた適切な状態であるか否かを判断すると共に、受信状態をもとに位置変更機構３０と回動機構４０とのうちのいずれを先に動作させるのかを判断する判断部２４を更に有する。例えば、判断部２４は、受信部２１によって受信された通信状態識別用信号の受信状態があらかじめ決められた適切な状態であるか否かを判断すると共に、当該通信状態識別用信号の受信状態をもとに位置変更機構３０と回動機構４０とのうちのいずれを先に動作させるのかを判断する。 The receiving device 20 determines whether or not the reception state of the signal received by the reception unit 21 is a predetermined appropriate state, and based on the reception state, the position change mechanism 30 and the rotation mechanism 40 It further includes a determination unit 24 that determines which of the above should be operated first. For example, the determination unit 24 determines whether the reception state of the communication state identification signal received by the reception unit 21 is an appropriate state determined in advance, and also determines the reception state of the communication state identification signal. It is determined which of the position change mechanism 30 and the rotation mechanism 40 is to be operated first.
　更に言うと、判断部２４は、受信部２１によって受信された通信状態識別用信号の信号雑音比があらかじめ決められた第１の設定値より小さい時間があらかじめ決められた第２の時間以上続く場合、位置変更機構３０を動作させる必要があると判断する。以下では、「信号雑音比」を「Ｓ／Ｎ比」と記載する。判断部２４は、受信部２１によって受信された通信状態識別用信号の強度があらかじめ決められた第２の設定値より小さい時間があらかじめ決められた第３の時間以上続く場合、回動機構４０を動作させる必要があると判断する。 Furthermore, when the determination unit 24 determines that the signal-to-noise ratio of the communication state identification signal received by the reception unit 21 is smaller than the first set value determined in advance, the determination continues to the second predetermined time or more. It is determined that the position change mechanism 30 needs to be operated. Below, "signal noise ratio" is described as "S / N ratio." If the time in which the strength of the communication state identification signal received by the reception unit 21 is smaller than the second predetermined value previously determined by the reception unit 21 continues for a predetermined third time or more, the rotation mechanism 40 It is determined that it is necessary to operate.
　判断部２４は、通信状態識別用信号のＳ／Ｎ比が第１の設定値より小さい時間が第２の時間以上続くと共に、通信状態識別用信号の強度が第２の設定値より小さい時間が第３の時間以上続く場合、回動機構４０より位置変更機構３０を先に動作させ、位置変更機構３０を動作させた後に回動機構４０を動作させると判断する。位置変更機構３０及び回動機構４０はいずれも、判断部２４によって判断された結果をもとに動作する。実施の形態１では、信号処理部２２、演算処理部２３及び判断部２４は、マイクロコンピュータによって実現されている。 The determination unit 24 continues the time during which the S / N ratio of the communication state identification signal is smaller than the first set value for the second time or longer, and the time when the strength of the communication state identification signal is smaller than the second set value If the operation continues for the third time or more, it is determined that the position change mechanism 30 is operated earlier than the rotation mechanism 40 and the rotation mechanism 40 is operated after the position change mechanism 30 is operated. The position change mechanism 30 and the rotation mechanism 40 both operate based on the result determined by the determination unit 24. In the first embodiment, the signal processing unit 22, the arithmetic processing unit 23, and the determination unit 24 are realized by a microcomputer.
　受信装置２０は、位置変更機構３０が動作すると共に回動機構４０が動作して受信部２１によって受信された信号の受信状態があらかじめ決められた適切な状態になった場合、受信状態が適切な状態であることを示す情報を報知する報知部２５を更に有する。報知部２５は、ブザーと発光ダイオードとを有しており、ブザーと発光ダイオードとの一方又は双方を用いて当該情報を報知する。 When the position change mechanism 30 operates and the rotation mechanism 40 operates so that the reception state of the signal received by the reception unit 21 becomes a predetermined appropriate state, the reception state is appropriate. It further has a notification unit 25 that notifies information indicating that it is a state. The notification unit 25 includes a buzzer and a light emitting diode, and uses one or both of the buzzer and the light emitting diode to notify the information.
　図２は、実施の形態１に係る通信システム１が有する受信装置２０、位置変更機構３０及び回動機構４０の平面を模式的に示す第１図である。位置変更機構３０の例は、ひとつの軸において伸縮する機能を有するピエゾ素子である。回動機構４０の例は、ステッピングモータである。実施の形態１では、位置変更機構３０の一方の端部が、開口が設けられている構造体５０の当該開口と対応する面に取り付けられている。 FIG. 2 is a first view schematically showing a plane of the receiving device 20, the position changing mechanism 30, and the turning mechanism 40 which the communication system 1 according to the first embodiment has. An example of the position change mechanism 30 is a piezo element having a function of expanding and contracting in one axis. An example of the pivoting mechanism 40 is a stepping motor. In the first embodiment, one end of the position changing mechanism 30 is attached to the surface corresponding to the opening of the structure 50 in which the opening is provided.
　回動機構４０は、位置変更機構３０の他方の端部に取り付けられている。平面視において、受信装置２０は、回動機構４０の中心に取り付けられている。更に言うと、平面視において、受信装置２０の中心が回動機構４０の中心に取り付けられている。図２における一点鎖線で示されている三角形は、受信装置２０が信号を受信することができる範囲を示している。 The pivoting mechanism 40 is attached to the other end of the position changing mechanism 30. In plan view, the receiving device 20 is attached to the center of the turning mechanism 40. Furthermore, in plan view, the center of the receiver 20 is attached to the center of the pivot mechanism 40. A triangle indicated by an alternate long and short dash line in FIG. 2 indicates the range in which the receiver 20 can receive a signal.
　位置変更機構３０は、ひとつの軸において伸縮することにより、受信装置２０の位置を変更することができる。回動機構４０は、平面視において、受信装置２０の中心を基準に受信装置２０を回動させることができる。具体的には、位置変更機構３０は、動作する場合、受信装置２０の位置を変更して受信部２１によって受信された通信状態識別用信号のＳ／Ｎ比が最大となった位置に受信装置２０を設定する。回動機構４０は、動作する場合、受信装置２０を回動させて受信部２１によって受信された通信状態識別用信号の強度が最大となった角度に受信装置２０を設定する。 The position change mechanism 30 can change the position of the receiving device 20 by expanding and contracting in one axis. The turning mechanism 40 can turn the receiving device 20 around the center of the receiving device 20 in plan view. Specifically, when the position change mechanism 30 operates, the position of the reception device 20 is changed, and the reception device is located at a position where the S / N ratio of the communication state identification signal received by the reception unit 21 is maximized. Set 20 When the rotation mechanism 40 operates, the rotation mechanism 40 rotates the reception device 20 to set the reception device 20 at an angle at which the strength of the communication state identification signal received by the reception unit 21 is maximized.
　報知部２５は、位置変更機構３０が、通信状態識別用信号のＳ／Ｎ比が最大である位置に受信装置２０を設定し、回動機構４０が、通信状態識別用信号の強度が最大である角度に受信装置２０を設定した後に、受信状態が適切な状態であることを示す情報を報知する。 In the notification unit 25, the position change mechanism 30 sets the reception device 20 at a position where the S / N ratio of the communication state identification signal is maximum, and the rotation mechanism 40 has a maximum strength of the communication state identification signal. After setting the receiving device 20 to a certain angle, information indicating that the reception state is an appropriate state is notified.
　演算処理部２３は、位置変更機構３０によって設定された受信装置２０の位置と、回動機構４０によって設定された受信装置２０の角度とを記憶する。具体的には、演算処理部２３が有する記憶部が、位置変更機構３０によって設定された受信装置２０の位置と、回動機構４０によって設定された受信装置２０の角度とを記憶する。 The arithmetic processing unit 23 stores the position of the reception device 20 set by the position change mechanism 30 and the angle of the reception device 20 set by the rotation mechanism 40. Specifically, the storage unit included in the arithmetic processing unit 23 stores the position of the receiving device 20 set by the position change mechanism 30 and the angle of the receiving device 20 set by the rotation mechanism 40.
　次に、実施の形態１に係る通信システム１の動作の例を説明する。まず、通信システム１が有する送信装置１０の動作の例を説明する。図３は、実施の形態１に係る通信システム１が有する送信装置１０の動作の手順の例を示すフローチャートである。ユーザは、受信装置２０に送信される信号のもとになる操作を操作部１１に対して行う。検出部１２は、操作部１１に対して行われたユーザの操作を検出する（Ｓ１）。 Next, an example of the operation of the communication system 1 according to the first embodiment will be described. First, an example of the operation of the transmission device 10 included in the communication system 1 will be described. FIG. 3 is a flowchart illustrating an example of an operation procedure of the transmission device 10 included in the communication system 1 according to the first embodiment. The user performs an operation on the operation unit 11 that is the source of the signal transmitted to the receiving device 20. The detection unit 12 detects a user operation performed on the operation unit 11 (S1).
　処理部１３は、検出部１２によって検出されたユーザの操作が通信調整モードを設定する操作であるか否かを判断する（Ｓ２）。処理部１３は、ユーザの操作が通信調整モードを設定する操作でないと判断した場合（Ｓ２でＮｏ）、リモートコントロールデータ信号の送信が必要であるか否かを判断する（Ｓ３）。リモートコントロールデータ信号の送信が必要であると処理部１３によって判断された場合（Ｓ３でＹｅｓ）、信号生成部１４は、ユーザの操作の内容に対応したリモートコントロールデータ信号を生成し、送信部１５は、生成されたリモートコントロールデータ信号を光信号に変換して受信装置２０に送信する（Ｓ４）。 The processing unit 13 determines whether the user's operation detected by the detection unit 12 is an operation to set the communication adjustment mode (S2). If the processing unit 13 determines that the user's operation is not an operation for setting the communication adjustment mode (No in S2), the processing unit 13 determines whether it is necessary to transmit a remote control data signal (S3). When it is determined by the processing unit 13 that transmission of the remote control data signal is necessary (Yes in S3), the signal generation unit 14 generates a remote control data signal corresponding to the content of the user operation, and the transmission unit 15 Converts the generated remote control data signal into an optical signal and transmits it to the receiving device 20 (S4).
　ステップＳ４の処理が行われた後、信号生成部１４は通信状態識別用信号を生成し、送信部１５は生成された通信状態識別用信号を光信号に変換して受信装置２０に送信する（Ｓ５）。信号生成部１４によって生成される通信状態識別用信号は、あらかじめ決められた特定の周波数の矩形波の信号である。送信部１５は、光信号に変換された通信状態識別用信号をあらかじめ決められた一定の時間送信する。 After the process of step S4 is performed, the signal generation unit 14 generates a communication state identification signal, and the transmission unit 15 converts the generated communication state identification signal into an optical signal and transmits it to the receiving device 20 (see FIG. S5). The communication state identification signal generated by the signal generation unit 14 is a rectangular wave signal of a predetermined frequency. The transmitting unit 15 transmits the communication state identification signal converted into the optical signal for a predetermined time.
　リモートコントロールデータ信号の送信は不要であると処理部１３によって判断された場合（Ｓ３でＮｏ）、及び、ステップＳ５の処理が行われた場合、処理部１３は、ユーザの操作をもとにした処理が終了したと判断する。送信装置１０は、動作を終了する。 If it is determined by the processing unit 13 that transmission of the remote control data signal is unnecessary (No in S3), and if the processing of step S5 is performed, the processing unit 13 is based on the user's operation. It is determined that the processing has ended. The transmitter 10 ends the operation.
　ユーザの操作が通信調整モードを設定する操作であると処理部１３によって判断された場合（Ｓ２でＹｅｓ）、信号生成部１４は通信状態識別用信号を生成し、送信部１５は生成された通信状態識別用信号を光信号に変換して受信装置２０に送信する（Ｓ６）。信号生成部１４によって生成される通信状態識別用信号は、上記の特定の周波数の矩形波の信号である。送信部１５は、光信号に変換された通信状態識別用信号を上記のあらかじめ決められた第１の時間送信する。 If the processing unit 13 determines that the user's operation is an operation to set the communication adjustment mode (Yes in S2), the signal generation unit 14 generates a communication state identification signal, and the transmission unit 15 generates the generated communication. The state identification signal is converted into an optical signal and transmitted to the receiver 20 (S6). The communication state identification signal generated by the signal generation unit 14 is a rectangular wave signal of the above-mentioned specific frequency. The transmitting unit 15 transmits the communication state identification signal converted into the optical signal for the above-described first predetermined time.
　ステップＳ６の処理が行われた後、処理部１３は、通信調整モードを解除する操作がユーザによって行われたか否かを判断する（Ｓ７）。ユーザは、通信調整モードを解除する場合、通信調整モードを解除するための操作を操作部１１に対して行う。検出部１２は、通信調整モードを解除するための操作が操作部１１に対して行われた場合、当該操作を検出する。処理部１３は、検出部１２が通信調整モードを解除するための操作を検出した場合、通信調整モードを解除する操作がユーザによって行われたと判断する。処理部１３は、検出部１２が通信調整モードを解除するための操作を検出しなかった場合、通信調整モードを解除する操作がユーザによって行われなかったと判断する。 After the process of step S6 is performed, the processing unit 13 determines whether an operation for canceling the communication adjustment mode has been performed by the user (S7). When the user cancels the communication adjustment mode, the user performs an operation on the operation unit 11 to cancel the communication adjustment mode. When an operation for releasing the communication adjustment mode is performed on the operation unit 11, the detection unit 12 detects the operation. When the detection unit 12 detects an operation for releasing the communication adjustment mode, the processing unit 13 determines that the operation for releasing the communication adjustment mode has been performed by the user. When the detection unit 12 does not detect the operation for canceling the communication adjustment mode, the processing unit 13 determines that the operation for canceling the communication adjustment mode has not been performed by the user.
　処理部１３は、通信調整モードを解除する操作がユーザによって行われなかったと判断した場合（Ｓ７でＮｏ）、通信調整モードが送信装置１０に設定された時からの経過時間があらかじめ決められた第４の時間を超えているか否かを判断する（Ｓ８）。当該経過時間が第４の時間以下であると処理部１３によって判断された場合（Ｓ８でＮｏ）、送信装置１０の動作はステップＳ６に移行する。 When the processing unit 13 determines that the user has not performed the operation of releasing the communication adjustment mode (No in S7), the elapsed time from when the communication adjustment mode is set to the transmission device 10 is predetermined. It is determined whether the time 4 has been exceeded (S8). When the processing unit 13 determines that the elapsed time is equal to or less than the fourth time (No in S8), the operation of the transmission device 10 proceeds to step S6.
　処理部１３は、通信調整モードを解除する操作がユーザによって行われたと判断した場合（Ｓ７でＹｅｓ）、及び、通信調整モードが設定された時からの経過時間が第４の時間を超えていると判断した場合（Ｓ８でＹｅｓ）、ユーザの操作をもとにした処理が終了したと判断する。送信装置１０は、動作を終了する。 If the processing unit 13 determines that the user has performed an operation to release the communication adjustment mode (Yes in S7), and the elapsed time from when the communication adjustment mode is set exceeds the fourth time. If it is determined that (Yes in S8), it is determined that the process based on the user's operation is completed. The transmitter 10 ends the operation.
　次に、通信システム１が有する受信装置２０、回動機構４０及び位置変更機構３０の動作の例を説明する。図４は、実施の形態１に係る通信システム１が有する受信装置２０、回動機構４０及び位置変更機構３０の動作の手順の例を示すフローチャートである。図４において、ステップＳ２６、ステップＳ２７、ステップＳ２８及びステップＳ２９以外のステップは、受信装置２０によって行われる。 Next, an example of operations of the reception device 20, the rotation mechanism 40, and the position change mechanism 30 included in the communication system 1 will be described. FIG. 4 is a flowchart showing an example of the procedure of operations of the reception device 20, the pivot mechanism 40, and the position change mechanism 30 which the communication system 1 according to the first embodiment has. In FIG. 4, steps other than step S26, step S27, step S28 and step S29 are performed by the receiving device 20.
　受信部２１は、送信装置１０から送信された信号を受信する（Ｓ１１）。受信部２１によって受信された信号は光信号であるので、受信部２１は受信した光信号を電気信号に変換する。信号処理部２２は、受信部２１によって受信された信号が通信状態識別用信号であるか否かを判断する（Ｓ１２）。 The receiving unit 21 receives the signal transmitted from the transmitting device 10 (S11). Since the signal received by the receiver 21 is an optical signal, the receiver 21 converts the received optical signal into an electrical signal. The signal processing unit 22 determines whether the signal received by the receiving unit 21 is a communication state identification signal (S12).
　受信部２１によって受信された信号が通信状態識別用信号でないと信号処理部２２によって判断された場合（Ｓ１２でＮｏ）、演算処理部２３は、受信部２１によって受信された信号が示す内容に対応する処理を実行する（Ｓ１３）。演算処理部２３は、ステップＳ１３の処理を実行した後、受信装置２０の処理が終了したと判断する。受信装置２０は、動作を終了する。 If the signal processing unit 22 determines that the signal received by the receiving unit 21 is not the communication state identification signal (No in S12), the arithmetic processing unit 23 responds to the content indicated by the signal received by the receiving unit 21. To execute the process (S13). After executing the process of step S13, the arithmetic processing unit 23 determines that the process of the receiving device 20 has ended. The receiving device 20 ends the operation.
　受信部２１によって受信された信号が通信状態識別用信号であると信号処理部２２によって判断された場合（Ｓ１２でＹｅｓ）、判断部２４は、通信状態識別用信号のＳ／Ｎ比があらかじめ決められた第１の設定値を超えているか否かを判断する（Ｓ１４）。 When the signal processing unit 22 determines that the signal received by the receiving unit 21 is the communication state identification signal (Yes in S12), the determination unit 24 determines in advance the S / N ratio of the communication state identification signal. It is determined whether the first set value is exceeded (S14).
　判断部２４は、通信状態識別用信号のＳ／Ｎ比が第１の設定値以下であると判断した場合（Ｓ１４でＮｏ）、当該Ｓ／Ｎ比が第１の設定値以下であることを示す情報を演算処理部２３に記録する（Ｓ１５）。演算処理部２３は、当該情報を記憶する。演算処理部２３は、通信状態識別用信号のＳ／Ｎ比が第１の設定値以下であった回数があらかじめ決められた第１の設定回数以下であるか否かを判断する（Ｓ１６）。ステップＳ１６の処理が行われた後の受信装置２０の動作については、後述する。 If the determination unit 24 determines that the S / N ratio of the communication state identification signal is less than or equal to the first set value (No in S14), the S / N ratio is less than or equal to the first set value. The information shown is recorded in the arithmetic processing unit 23 (S15). The arithmetic processing unit 23 stores the information. The arithmetic processing unit 23 determines whether the number of times the S / N ratio of the communication state identification signal is less than or equal to the first set value is less than or equal to the first set number previously determined (S16). The operation of the receiving device 20 after the process of step S16 is performed will be described later.
　判断部２４は、通信状態識別用信号のＳ／Ｎ比が第１の設定値を超えていると判断した場合（Ｓ１４でＹｅｓ）、演算処理部２３に記憶されているＳ／Ｎ比が第１の設定値以下であった回数をリセットする（Ｓ１７）。つまり、ステップＳ１７において、判断部２４は、演算処理部２３に記憶されているＳ／Ｎ比が第１の設定値以下であった回数を「０」に設定する。 If the determination unit 24 determines that the S / N ratio of the communication state identification signal exceeds the first set value (Yes in S14), the S / N ratio stored in the arithmetic processing unit 23 The number of times of being equal to or less than the set value of 1 is reset (S17). That is, in step S17, the determination unit 24 sets the number of times the S / N ratio stored in the arithmetic processing unit 23 is less than or equal to the first set value to “0”.
　ステップＳ１７の処理が行われた後、判断部２４は、通信状態識別用信号の強度があらかじめ決められた第２の設定値を超えているか否かを判断する（Ｓ１８）。判断部２４は、演算処理部２３に記憶されているＳ／Ｎ比が第１の設定値以下であった回数が第１の設定回数以下であると演算処理部２３によって判断された場合（Ｓ１６でＹｅｓ）にも、通信状態識別用信号の強度が第２の設定値を超えているか否かを判断する（Ｓ１８）。判断部２４は、通信状態識別用信号の強度が第２の設定値以下であると判断した場合（Ｓ１８でＮｏ）、通信状態識別用信号の強度が第２の設定値以下であったことを示す情報を演算処理部２３に記録する（Ｓ１９）。演算処理部２３は、当該情報を記憶する。 After the process of step S17 is performed, the determination unit 24 determines whether the strength of the communication state identification signal exceeds a predetermined second set value (S18). If the arithmetic processing unit 23 determines that the number of times the S / N ratio stored in the arithmetic processing unit 23 is less than or equal to the first set value is equal to or less than the first set number (S16) Also, it is determined whether the strength of the communication state identification signal exceeds the second set value (S18). When the determination unit 24 determines that the strength of the communication state identification signal is less than or equal to the second set value (No in S18), the strength of the communication state identification signal is less than or equal to the second set value. The information shown is recorded in the arithmetic processing unit 23 (S19). The arithmetic processing unit 23 stores the information.
　ステップＳ１９の処理が行われた後、演算処理部２３は、通信状態識別用信号の強度が第２の設定値以下であった回数が第２の設定回数以下であるか否かを判断する（Ｓ２０）。ステップＳ２０の処理が行われた後の受信装置２０の動作については、後述する。 After the process of step S19 is performed, the arithmetic processing unit 23 determines whether the number of times the strength of the communication state identification signal is less than or equal to the second set value is less than or equal to the second set number S20). The operation of the receiving device 20 after the process of step S20 is performed will be described later.
　判断部２４は、通信状態識別用信号の強度が第２の設定値を超えていると判断した場合（Ｓ１８でＹｅｓ）、演算処理部２３に記憶されている通信状態識別用信号の強度が第２の設定値以下であった回数をリセットする（Ｓ２１）。つまり、ステップＳ２１において、判断部２４は、演算処理部２３に記憶されている通信状態識別用信号の強度が第２の設定値以下であった回数を「０」に設定する。 If the determination unit 24 determines that the strength of the communication state identification signal exceeds the second set value (Yes in S18), the strength of the communication state identification signal stored in the arithmetic processing unit 23 is The number of times of being less than or equal to the set value of 2 is reset (S21). That is, in step S21, the determination unit 24 sets the number of times that the strength of the communication state identification signal stored in the arithmetic processing unit 23 is less than or equal to the second set value to "0".
　演算処理部２３に記憶されているＳ／Ｎ比が第１の設定値以下であった回数が第１の設定回数を超えていると演算処理部２３によって判断された場合（Ｓ１６でＮｏ）、及び、演算処理部２３に記憶されている通信状態識別用信号の強度が第２の設定値以下であった回数が第２の設定回数を超えていると演算処理部２３によって判断された場合（Ｓ２０でＮｏ）、報知部２５は、受信状態があらかじめ決められている適切な状態でないことを報知する（Ｓ２２）。例えば、ステップＳ２２において、報知部２５は、ブザーと発光ダイオードとの一方又は双方を用いて、受信状態が適切な状態でないことを報知する。 When it is determined by the arithmetic processing unit 23 that the number of times the S / N ratio stored in the arithmetic processing unit 23 is less than or equal to the first set value exceeds the first set number (No in S16), And the arithmetic processing unit 23 determines that the number of times the strength of the communication state identification signal stored in the arithmetic processing unit 23 is less than or equal to the second set value exceeds the second set number ( In S20, the notification unit 25 notifies that the reception state is not an appropriate state determined in advance (S22). For example, in step S22, the notification unit 25 uses one or both of a buzzer and a light emitting diode to notify that the reception state is not an appropriate state.
　ステップＳ２２の処理が行われた後、判断部２４は、演算処理部２３に記憶されている通信状態識別用信号の強度が第２の設定値以下であった回数をリセットすると共に、演算処理部２３に記憶されているＳ／Ｎ比が第１の設定値以下であった回数をリセットする（Ｓ２３）。判断部２４は、ステップＳ２３の処理を行うと、受信装置２０の処理が終了したと判断する。受信装置２０は、動作を終了する。 After the process of step S22 is performed, the determination unit 24 resets the number of times the strength of the communication state identification signal stored in the arithmetic processing unit 23 is less than or equal to the second set value, and the arithmetic processing unit The number of times the S / N ratio stored in S23 is less than or equal to the first set value is reset (S23). After performing the process of step S23, the determining unit 24 determines that the process of the receiving device 20 is completed. The receiving device 20 ends the operation.
　ステップＳ２１において演算処理部２３に記憶されている通信状態識別用信号の強度が第２の設定値以下であった回数が判断部２４によってリセットされた後、演算処理部２３は、受信部２１による通信状態識別用信号の受信時間があらかじめ決められた設定時間より長いか否かを判断する（Ｓ２４）。演算処理部２３は、演算処理部２３が記憶している通信状態識別用信号の強度が第２の設定値以下であった回数が第２の設定回数以下であると判断した場合（Ｓ２０でＹｅｓ）にも、上記の受信時間が設定時間より長いか否かを判断する（Ｓ２４）。 After the number of times the strength of the communication state identification signal stored in the arithmetic processing unit 23 is less than or equal to the second set value in step S21 is reset by the determination unit 24, the arithmetic processing unit 23 It is determined whether the reception time of the communication state identification signal is longer than the predetermined time determined in advance (S24). If arithmetic processing unit 23 determines that the number of times the strength of the communication state identification signal stored in arithmetic processing unit 23 is less than or equal to the second set value is less than or equal to the second set number (Yes in S20) Also, it is determined whether the above reception time is longer than the set time (S24).
　演算処理部２３は、受信部２１による通信状態識別用信号の受信時間が設定時間以下であると判断した場合（Ｓ２４でＮｏ）、通信状態識別用信号は図３のステップＳ５において送信された信号であると判断する。受信装置２０は、動作を終了する。 When the arithmetic processing unit 23 determines that the reception time of the communication state identification signal by the reception unit 21 is equal to or less than the set time (No in S24), the communication state identification signal is the signal transmitted in step S5 of FIG. It is determined that The receiving device 20 ends the operation.
　演算処理部２３は、受信部２１による通信状態識別用信号の受信時間が設定時間より長いと判断した場合（Ｓ２４でＹｅｓ）、通信調整モードが送信装置１０に設定されていると判断し、通信状態識別用信号のＳ／Ｎ比が第１の設定値以下であった回数が０回であって、かつ、通信状態識別用信号の強度が第２の設定値以下であった回数が１回以上であるか否かを判断する（Ｓ２５）。 When the arithmetic processing unit 23 determines that the reception time of the communication state identification signal by the reception unit 21 is longer than the set time (Yes in S24), the arithmetic processing unit 23 determines that the communication adjustment mode is set to the transmission device 10 and performs communication The number of times the S / N ratio of the state identification signal is less than or equal to the first set value is zero, and the number of times the strength of the communication state identification signal is less than or equal to the second set value is one.

The reception angle is adjusted, and the reception device 20 is set to an angle at which the strength of the communication state identification signal falls within the predetermined setting range (S26).
　ステップＳ２６の処理が行われた後、位置変更機構３０は、受信装置２０の位置を調整し、通信状態識別用信号のＳ／Ｎ比があらかじめ決められた設定範囲に収まる位置に受信装置２０を設定する（Ｓ２７）。 After the process of step S26 is performed, the position changing mechanism 30 adjusts the position of the receiving device 20, and the receiving device 20 is positioned at a position where the S / N ratio of the communication state identification signal falls within a predetermined setting range.

　通信状態識別用信号のＳ／Ｎ比が第１の設定値以下であった回数が０回でないか、又は、通信状態識別用信号の強度が第２の設定値以下であった回数が０回であると演算処理部２３によって判断された場合（Ｓ２５でＮｏ）、位置変更機構３０は、受信装置２０の位置を調整し、Ｓ／Ｎ比があらかじめ決められた設定範囲に収まる位置に受信装置２０を設定する（Ｓ２８）。 The number of times the S / N ratio of the communication state identification signal is less than or equal to the first set value is not zero, or the number of times the strength of the communication state identification signal is less than or equal to the second set value is zero If it is determined by the arithmetic processing unit 23 (No in S25), the position changing mechanism 30 adjusts the position of the receiving device 20, and the receiving device is positioned at a position where the S / N ratio falls within a predetermined setting range. Set 20 (S28).
　ステップＳ２８の処理が行われた後、回動機構４０は、受信装置２０を回動させて受信装置２０が通信状態識別用信号を受信する際の受信装置２０の受信角度を調整し、通信状態識別用信号の強度があらかじめ決められた設定範囲に収まる角度に受信装置２０を設定する（Ｓ２９）。 After the process of step S28 is performed, the rotation mechanism 40 rotates the reception device 20 to adjust the reception angle of the reception device 20 when the reception device 20 receives the communication state identification signal, and the communication state is performed. The receiver 20 is set to an angle at which the strength of the identification signal falls within a predetermined setting range (S29).
　ステップＳ２７の処理が行われた後、及び、ステップＳ２９の処理が行われた後、判断部２４は、演算処理部２３に記憶されている通信状態識別用信号の強度が第２の設定値以下であった回数をリセットすると共に、演算処理部２３に記憶されているＳ／Ｎ比が第１の設定値以下であった回数をリセットする（Ｓ３０）。 After the process of step S27 is performed and after the process of step S29 is performed, the determination unit 24 determines that the strength of the communication state identification signal stored in the arithmetic processing unit 23 is less than or equal to the second set value. While resetting the number of times, the number of times that the S / N ratio stored in the arithmetic processing unit 23 is less than or equal to the first set value is reset (S30).
　ステップＳ３０の処理が行われた後、判断部２４は、通信状態識別用信号のＳ／Ｎ比が第１の設定値以上であって、かつ、通信状態識別用信号の強度が第２の設定値以上であるか否かを判断する（Ｓ３１）。通信状態識別用信号のＳ／Ｎ比が第１の設定値より小さい、又は、通信状態識別用信号の強度が第２の設定値より小さいと判断部２４によって判断された場合（Ｓ３１でＮｏ）、受信装置２０の動作はステップＳ１４に移行する。 After the process of step S30 is performed, the determination unit 24 determines that the S / N ratio of the communication state identification signal is greater than or equal to the first set value, and the strength of the communication state identification signal indicates the second setting. It is judged whether it is more than a value (S31).

The arithmetic processing unit 23 stores the set position and the reception angle of the receiving device 20. The notification unit 25 notifies that the reception state is an appropriate predetermined state (S33). For example, in step S33, the notification unit 25 uses one or both of a buzzer and a light emitting diode to notify that the reception state is an appropriate state.
　ステップＳ３３の処理が行われた後、判断部２４は受信装置２０の処理が終了したと判断する。受信装置２０、回動機構４０及び位置変更機構３０は、動作を終了する。 After the process of step S33 is performed, the determining unit 24 determines that the process of the receiving device 20 is completed.
