本発明は、設置後の電波状況変化を考慮したテスト通信を容易に行うことができる無線通信装置及び無線通信システムに関する。  The present invention relates to a wireless communication apparatus and a wireless communication system that can easily perform test communication in consideration of changes in radio wave conditions after installation.

従来、火災感知器、ガス漏れ警報器等の防災端末機が火災等の異常を検知した場合に、通信ネットワークを介して集中監視センタに自動的に通報する自動通報無線通信システムが知られている。  Conventionally, an automatic notification wireless communication system that automatically notifies a centralized monitoring center via a communication network when a disaster prevention terminal such as a fire detector or a gas leak alarm detects an abnormality such as a fire is known. .

自動通報無線通信システムは、防災端末に無線子機を接続し、通信ネットワークに接続される網制御装置に無線親機を接続して、防災端末で火災等の異常が検知された場合に、無線子機から無線親機へ異常情報を無線送信し、通信ネットワークを介して集中監視センタ等に通報する。  An automatic notification wireless communication system connects a wireless slave unit to a disaster prevention terminal, connects a wireless master unit to a network control device connected to a communication network, and wirelessly detects an abnormality such as a fire at the disaster prevention terminal. Abnormal information is wirelessly transmitted from the slave unit to the wireless master unit, and notified to a centralized monitoring center or the like via a communication network.

上記のような自動通報無線通信システムにおいて、無線子機及び無線親機を新規に設置する場合、設置する無線親機と無線子機間で電波が十分とどいているかどうかを確認する必要がある。この電波状況を確認する手段としては、無線機の設置場所近傍に電界強度測定器等を設置して電界強度を測定して判断する場合(例えば、特許文献1)や、無線親機及び無線子機間で実際に無線通信を行った結果で判断する場合が多い。

As a means for confirming the radio wave condition, a case where a field strength measuring device or the like is installed in the vicinity of a place where the wireless device is installed to measure and determine the field strength (for example, Patent Document 1), or a wireless master device and a wireless device.

しかしながら、上記のように電界強度測定器等によって電波状況を確認する場合、電界強度測定器の設置場所と無線機の設置場所を同一にすることは難しく、また、設置する場所の周囲環境も刻々と変化するため、運用時とテスト通信時の環境を同一にすることは非常に困難であるため、正確な電界強度測定が行えない。  However, when confirming the radio wave condition with an electric field strength measuring instrument as described above, it is difficult to make the installation location of the electric field strength measuring device and the wireless device the same, and the surrounding environment of the installation location is also constantly Therefore, it is very difficult to make the environment during operation and test communication the same, so accurate field strength measurement cannot be performed.

また、無線親機および無線子機間で実際に無線通信を行う場合、設置時の通信確認では良好な結果が得られていた場合でも、その後家具等の配置変更や、昼夜で周囲環境の変化等により電波状況が悪化し、通信できなくなるという問題があった。  In addition, when actually performing wireless communication between the wireless master unit and the wireless slave unit, even if good results have been obtained in the communication confirmation at the time of installation, the arrangement of furniture, etc. is changed afterwards, and the surrounding environment changes day and night. There was a problem that the radio wave condition deteriorated due to, etc., and communication became impossible.

本発明の課題は、運用時に無線通信ができるかどうかの確認が容易に行え、設置後に家具等の配置変更や、昼夜で周囲環境の変化等が発生した場合でもより高い通信品質の確保ができる無線通信装置及び無線通信システムを提供することにある。  The problem of the present invention is that it is easy to check whether wireless communication is possible during operation, and it is possible to ensure higher communication quality even when the arrangement of furniture etc. is changed after installation or the surrounding environment changes during the day and night. To provide a wireless communication apparatus and a wireless communication system.

本発明は、上記課題を解決するために以下の手段を採用した。請求項1の発明は、無線信号を受信する受信部と、前記無線信号の電界強度を測定する電界強度測定部と、前記無線信号の電文を解析して、前記無線信号が、電波状況を確認するテスト通信であることを示すテスト信号であるかどうかを判断する電文解析部と、前記無線信号が前記テスト信号であった場合に、前記電界強度測定部により測定された電界強度が予め設定されたしきい値よりも小さいかどうかを判定して、前記電界強度が前記しきい値よりも小さいときに、エラー報知を行う制御部とを備えることを特徴とする。  The present invention employs the following means in order to solve the above problems. The invention of claim 1 is a receiver for receiving a radio signal, an electric field strength measuring unit for measuring the electric field strength of the radio signal, and analyzing a telegram of the radio signal to confirm that the radio signal is in a radio wave condition. A message analysis unit that determines whether or not the test signal indicates that the test communication is performed, and an electric field strength measured by the electric field strength measurement unit when the wireless signal is the test signal. A control unit that determines whether or not the threshold value is smaller than the threshold value, and performs error notification when the electric field strength is smaller than the threshold value.

請求項1の発明によれば、受信した無線信号がテスト信号であると判断されたときに、電界強度測定部で測定された電界強度と、予め設定されたしきい値とを比較して、測定された電界強度がしきい値よりも小さいときはエラー報知を行うので、無線通信装置を新規に設置する場合、設置後の電波状況変化を考慮して、運用時に無線通信ができるかどうかの確認を容易に行うことができ、設置後に家具等の配置変更や、昼夜で周囲環境の変化等が発生した場合でもより高い通信品質の確保ができる。  According to the invention of claim 1, when it is determined that the received radio signal is a test signal, the electric field intensity measured by the electric field intensity measuring unit is compared with a preset threshold value, When the measured electric field strength is smaller than the threshold value, an error notification is performed. Therefore, when newly installing a wireless communication device, whether or not wireless communication can be performed during operation, taking into account changes in radio wave conditions after installation. Confirmation can be easily performed, and higher communication quality can be ensured even when the arrangement of furniture or the like is changed after installation or the surrounding environment changes day and night.

以下、本発明の実施例に係る無線通信装置及び無線通信システムを図面を参照しながら詳細に説明する。なお、以下の実施例では本発明の無線通信装置及び無線通信システムを自動通報無線通信システムに適用した場合を例に説明する。  Hereinafter, a wireless communication apparatus and a wireless communication system according to an embodiment of the present invention will be described in detail with reference to the drawings. In the following embodiments, a case where the wireless communication device and the wireless communication system of the present invention are applied to an automatic notification wireless communication system will be described as an example.

図1は自動通報無線通信システムの概略構成図である。図1に示すように、自動通報無線通信システムは、無線親機1、網制御装置2、無線子機3、防災端末4を備えて構成され、無線親機1は網制御装置2及び通信ネットワーク100を介してセンタ装置101等の上位機器に接続され、無線子機3は火災感知器等の防災端末4に接続されている。本発明の無線通信装置は、図1の無線親機1または無線子機3である。  FIG. 1 is a schematic configuration diagram of an automatic notification wireless communication system. As shown in FIG. 1, the automatic notification wireless communication system includes a wireless master device 1, anetwork control device 2, awireless slave device 3, and adisaster prevention terminal 4. The wireless master device 1 includes thenetwork control device 2 and a communication network. Thewireless slave unit 3 is connected to adisaster prevention terminal 4 such as a fire detector. The wireless communication apparatus of the present invention is the wireless master device 1 or thewireless slave device 3 of FIG.

この自動通報無線通信システムは、防災端末4で異常が検知された場合に、無線子機3から無線親機1へ異常情報を無線送信し、通信ネットワーク100を介してセンタ装置101に通報する。また、無線親機1及び無線子機3を新規に設置する場合、無線親機1と無線子機3間で電波が十分とどいているかどうかを確認するためのテスト通信を行う。  When an abnormality is detected in thedisaster prevention terminal 4, the automatic notification wireless communication system wirelessly transmits abnormality information from thewireless slave unit 3 to the wireless master unit 1 and notifies thecenter device 101 via thecommunication network 100. Further, when the wireless master device 1 and thewireless slave device 3 are newly installed, test communication for confirming whether or not the radio wave is sufficiently maintained between the wireless master device 1 and thewireless slave device 3 is performed.

このテスト通信は、次のような手順で行われる。まず、テスト通信を開始するためのテスト起動信号を無線親機1から無線子機3へ無線送信する。次に、無線子機3はテスト起動信号に応答して、テスト信号を無線親機1へ無線送信する。無線親機1は、受信したテスト信号の電界強度が予め設定されたしきい値よりも大きいかどうかによって無線子機3と無線親機1間の電波状況を確認する。なお、テスト通信は、無線子機3から無線親機1へテスト起動信号を無線送信し、これに応答して無線親機1から無線子機3へテスト信号を無線送信するものとしてもよい。  This test communication is performed in the following procedure. First, a test activation signal for starting test communication is wirelessly transmitted from the wireless master device 1 to thewireless slave device 3. Next, thewireless slave device 3 wirelessly transmits the test signal to the wireless master device 1 in response to the test activation signal. The wireless master device 1 checks the radio wave condition between thewireless slave device 3 and the wireless master device 1 depending on whether the electric field strength of the received test signal is larger than a preset threshold value. In the test communication, a test activation signal may be wirelessly transmitted from thewireless slave device 3 to the wireless master device 1 and a test signal may be wirelessly transmitted from the wireless master device 1 to thewireless slave device 3 in response thereto.

図2は本発明の実施例1に係る無線親機1の機能構成を示すブロック図である。図2に示すように、無線親機1は、アンテナ5、受信回路部6、電界強度測定部7、送信回路部8、信号処理部9、電源回路部12、テスト通信起動部14及び報知部15を備えて構成されている。また、信号処理部9は、電文解析部10、制御回路部11及びしきい値設定部13を備えている。  FIG. 2 is a block diagram illustrating a functional configuration of the wireless master device 1 according to the first embodiment of the invention. As shown in FIG. 2, the wireless master device 1 includes anantenna 5, areception circuit unit 6, an electric fieldstrength measurement unit 7, atransmission circuit unit 8, a signal processing unit 9, a powersupply circuit unit 12, a testcommunication activation unit 14, and a notification unit. 15. The signal processing unit 9 includes amessage analysis unit 10, acontrol circuit unit 11, and athreshold setting unit 13.

受信回路部6は、アンテナ5を介して信号を無線受信する。送信回路部8は、アンテナ5を介して信号を無線送信する。電源回路部12は、信号処理部9に電源を供給する。  Thereceiving circuit unit 6 wirelessly receives a signal via theantenna 5. Thetransmission circuit unit 8 wirelessly transmits a signal via theantenna 5. The powersupply circuit unit 12 supplies power to the signal processing unit 9.

電界強度測定部7は、受信回路部6で受信した信号の電界強度を測定して測定値を制御回路部11に出力する。電文解析部10は、受信回路部6で受信した信号を制御回路部11に出力するとともに受信した信号の電文を解析して、テスト起動信号およびテスト信号であるかどうかを判断する。  The electric fieldstrength measuring unit 7 measures the electric field strength of the signal received by thereceiving circuit unit 6 and outputs the measured value to thecontrol circuit unit 11. Themessage analysis unit 10 outputs the signal received by thereception circuit unit 6 to thecontrol circuit unit 11 and analyzes the message of the received signal to determine whether the signal is a test activation signal and a test signal.

制御回路部11は、受信した信号がテスト起動信号およびテスト信号でない場合、信号を網制御装置2に出力する。制御回路部11は、受信した信号がテスト起動信号である場合、無線子機3に対してテスト信号を無線送信する。制御回路部11は、受信した信号がテスト信号である場合、電界強度測定部7から出力された電界強度の測定値と、しきい値設定部13に予め設定されたしきい値とを比較して、電界強度の測定値がしきい値よりも大きい場合は、信号を網制御装置2に出力する。電界強度の測定値がしきい値よりも小さい場合は、報知部15にエラー報知するとともにエラー報知電文を網制御装置2に出力して、通信を終了する。このとき、エラー報知電文を出力する替わりに網制御装置2に信号を出力せずに無応答状態として通信を終了してもよい。  Thecontrol circuit unit 11 outputs a signal to thenetwork control device 2 when the received signal is not the test activation signal and the test signal. When the received signal is a test activation signal, thecontrol circuit unit 11 wirelessly transmits a test signal to thewireless slave device 3. When the received signal is a test signal, thecontrol circuit unit 11 compares the measured value of the electric field strength output from the electric fieldstrength measuring unit 7 with a threshold value preset in the thresholdvalue setting unit 13. When the measured value of the electric field strength is larger than the threshold value, a signal is output to thenetwork control device 2. When the measured value of the electric field strength is smaller than the threshold value, an error is notified to thenotification unit 15 and an error notification message is output to thenetwork control device 2 to end the communication. At this time, instead of outputting the error notification message, the communication may be terminated in a non-response state without outputting a signal to thenetwork control device 2.

しきい値設定部13は、テスト通信時に受信回路部6で受信した信号の電界強度と比較されるしきい値が予め設定されている。このしきい値は、設置後の家具の配置変更による電波状況の変化や、昼夜での電波状況の変化や、フェージング等を考慮して設定される。  The thresholdvalue setting unit 13 is preset with a threshold value to be compared with the electric field strength of the signal received by thereceiving circuit unit 6 during test communication. This threshold value is set in consideration of a change in the radio wave condition due to a change in the arrangement of furniture after installation, a change in the radio wave condition between day and night, fading, and the like.

テスト通信起動部14は、無線親機1から無線子機3へテスト起動信号無線送信し、無線子機3から無線親機1へテスト信号を無線送信してテスト通信を行う場合に、テスト起動信号を制御回路部11に発生させるテスト起動信号発生手段である。テスト起動信号は、制御回路部11から送信回路部8に出力され、送信回路部8は、アンテナ5を介して、無線子機3に無線送信する。  The testcommunication activation unit 14 wirelessly transmits a test activation signal from the wireless master device 1 to thewireless slave device 3 and wirelessly transmits a test signal from thewireless slave device 3 to the wireless slave device 1 to perform test activation. This is a test activation signal generating means for causing thecontrol circuit section 11 to generate a signal. The test activation signal is output from thecontrol circuit unit 11 to thetransmission circuit unit 8, and thetransmission circuit unit 8 wirelessly transmits to thewireless slave device 3 via theantenna 5.

図3は本発明の実施例1に係る無線子機3の機能構成を示すブロック図である。図3に示すように、無線子機3は、アンテナ16、受信回路部17、電界強度測定部18、送信回路部19、信号処理部20、電源回路部23、テスト通信起動部26及び報知部25を備えて構成されている。また、信号処理部20は、電文解析部21、制御回路部22及びしきい値設定部24を備えている。  FIG. 3 is a block diagram showing a functional configuration of thewireless slave device 3 according to the first embodiment of the present invention. As shown in FIG. 3, thewireless slave device 3 includes anantenna 16, areception circuit unit 17, an electric fieldstrength measurement unit 18, atransmission circuit unit 19, a signal processing unit 20, a powersupply circuit unit 23, a test communication activation unit 26, and a notification unit. 25. The signal processing unit 20 includes amessage analysis unit 21, acontrol circuit unit 22, and athreshold setting unit 24.

受信回路部17は、アンテナ16を介して信号を無線受信する。送信回路部19は、アンテナ16を介して信号を無線送信する。電源回路部23は、信号処理部20に電源を供給する。  Thereceiving circuit unit 17 wirelessly receives a signal via theantenna 16. Thetransmission circuit unit 19 wirelessly transmits a signal via theantenna 16. The powersupply circuit unit 23 supplies power to the signal processing unit 20.

電界強度測定部18は、受信回路部17で受信した信号の電界強度を測定して測定値を制御回路部22に出力する。電文解析部21は、受信回路部17で受信した信号を制御回路部22に出力するとともに受信した信号の電文を解析して、テスト起動信号およびテスト信号であるかどうかを判断する。  The electric fieldstrength measuring unit 18 measures the electric field strength of the signal received by thereceiving circuit unit 17 and outputs the measured value to thecontrol circuit unit 22. Themessage analysis unit 21 outputs the signal received by thereception circuit unit 17 to thecontrol circuit unit 22 and analyzes the message of the received signal to determine whether the signal is a test activation signal and a test signal.

制御回路部22は、受信した信号がテスト起動信号およびテスト信号でない場合、通常の通信を行う。制御回路部22は、受信した信号がテスト起動信号である場合、無線親機1に対してテスト信号を無線送信する。制御回路部22は、受信した信号がテスト信号である場合、電界強度測定部18から出力された電界強度の測定値と、しきい値設定部24に予め設定されたしきい値とを比較して、電界強度の測定値がしきい値よりも大きい場合は、通常の通信を行う。電界強度の測定値がしきい値よりも小さい場合は、報知部25にエラー報知して、通信を終了する。  Thecontrol circuit unit 22 performs normal communication when the received signal is not the test activation signal and the test signal. When the received signal is a test activation signal, thecontrol circuit unit 22 wirelessly transmits a test signal to the wireless master device 1. When the received signal is a test signal, thecontrol circuit unit 22 compares the electric field intensity measurement value output from the electric fieldintensity measurement unit 18 with a threshold value preset in the thresholdvalue setting unit 24. When the measured value of the electric field strength is larger than the threshold value, normal communication is performed. If the measured value of the electric field strength is smaller than the threshold value, an error is notified to thenotification unit 25 and communication is terminated.

テスト通信起動部26は、無線子機3から無線親機1へテスト起動信号無線送信し、無線親機1から無線子機3へテスト信号を無線送信してテスト通信を行う場合に、テスト起動信号を制御回路部22に発生させるテスト起動信号発生手段である。テスト起動信号は、制御回路部22から送信回路部19に出力される。送信回路部19は、テスト起動信号をアンテナ16を介して、無線親機1に無線送信する。  The test communication activation unit 26 transmits a test activation signal wirelessly from thewireless slave unit 3 to the wireless master unit 1 and performs test communication when performing a test communication by wirelessly transmitting a test signal from the wireless master unit 1 to thewireless slave unit 3. This is a test activation signal generating means for causing thecontrol circuit unit 22 to generate a signal. The test activation signal is output from thecontrol circuit unit 22 to thetransmission circuit unit 19. Thetransmission circuit unit 19 wirelessly transmits a test activation signal to the wireless master device 1 via theantenna 16.

なお、無線子機3から無線親機1へテスト起動信号を無線送信して、テスト通信を行う場合、無線親機1の電界強度測定部7、しきい値設定部13、テスト通信起動部14、報知部15は省略可能である。また、テスト起動信号は防災端末4から出力され、制御回路部22に入力されるものとしてもよい。  In addition, when performing a test communication by wirelessly transmitting a test activation signal from thewireless slave device 3 to the wireless master device 1, the electric fieldstrength measuring unit 7, the thresholdvalue setting unit 13, and the testcommunication activation unit 14 of the wireless master device 1 are performed. Thenotification unit 15 can be omitted. The test activation signal may be output from thedisaster prevention terminal 4 and input to thecontrol circuit unit 22.

また、無線親機1から無線子機3へテスト起動信号を無線送信して、テスト通信を行う場合、無線子機3の電界強度測定部18、しきい値設定部24、テスト通信起動部26、報知部25は省略可能である。また、テスト起動信号はセンタ装置101から出力され、通信ネットワーク100及び網制御装置2を介して制御回路部11に入力されるものとしてもよい。  Also, when performing a test communication by wirelessly transmitting a test activation signal from the wireless master device 1 to thewireless slave device 3, the electric fieldstrength measuring unit 18, the thresholdvalue setting unit 24, and the test communication activation unit 26 of thewireless slave device 3 are performed. Thenotification unit 25 can be omitted. The test activation signal may be output from thecenter apparatus 101 and input to thecontrol circuit unit 11 via thecommunication network 100 and thenetwork control apparatus 2.

次に、本発明の実施例1に係る無線通信装置の動作を詳細に説明する。まず、無線子機3からの信号を無線親機1が無線受信する際の動作を図4に示すフローチャートを用いて説明する。無線親機1の受信回路部6は、アンテナ5を介して信号を無線受信する(ステップS1)。電界強度測定部7は、受信した信号の電界強度を測定して、測定値を制御回路部11に出力する(ステップS2)。電文解析部10は、受信した信号の電文を解析して、テスト信号であるかどうかを判断する(ステップS3)。受信した信号がテスト信号であった場合、制御回路部11は、電界強度の測定値と、しきい値設定部13に設定されたしきい値とを比較する(ステップS4)。電界強度の測定値がしきい値よりも小さいとき報知部15にエラー報知するとともにエラー報知電文を網制御装置2に出力して(ステップS5)、通信を終了する(ステップS7)。ステップS3で、受信した信号がテスト信号でない場合またはステップS4で、電界強度の測定値がしきい値よりも大きい場合、制御回路部11は、信号を網制御装置2に出力して通常の通信を行い(ステップS6)、通信を終了する(ステップS7)。  Next, the operation of the wireless communication apparatus according to the first embodiment of the present invention will be described in detail. First, the operation when the wireless master device 1 wirelessly receives a signal from thewireless slave device 3 will be described with reference to the flowchart shown in FIG. The receivingcircuit unit 6 of the wireless master device 1 wirelessly receives a signal via the antenna 5 (step S1). The electric fieldstrength measuring unit 7 measures the electric field strength of the received signal and outputs the measured value to the control circuit unit 11 (step S2). Themessage analysis unit 10 analyzes the message of the received signal and determines whether it is a test signal (step S3). If the received signal is a test signal, thecontrol circuit unit 11 compares the measured value of the electric field strength with the threshold value set in the threshold value setting unit 13 (step S4). When the measured value of the electric field strength is smaller than the threshold value, an error is notified to thenotification unit 15 and an error notification message is output to the network control device 2 (step S5), and the communication is terminated (step S7). If the received signal is not a test signal in step S3 or if the measured value of the electric field strength is larger than the threshold value in step S4, thecontrol circuit unit 11 outputs the signal to thenetwork control device 2 to perform normal communication. (Step S6) and the communication is terminated (Step S7).

次に、無線親機1からの信号を無線子機3が無線受信する際の動作を図5に示すフローチャートを用いて説明する。無線子機3の受信回路部17は、アンテナ16を介して信号を無線受信する(ステップS11)。電界強度測定部18は、受信した信号の電界強度を測定して、測定値を制御回路部22に出力する(ステップS12)。電文解析部21は、受信した信号の電文を解析して、テスト信号であるかどうかを判断する(ステップS13)。受信した信号がテスト信号であった場合、制御回路部22は、電界強度の測定値と、しきい値設定部24に設定されたしきい値とを比較する(ステップS14)。電界強度の測定値がしきい値よりも小さいとき報知部25にエラー報知して(ステップS15)、通信を終了する(ステップS17)。ステップS13で、受信した信号がテスト信号でない場合またはステップS14で、電界強度の測定値がしきい値よりも大きい場合、制御回路部22は、通常の通信を行い(ステップS16)、通信を終了する(ステップS17)。  Next, the operation when thewireless slave device 3 wirelessly receives a signal from the wireless master device 1 will be described with reference to the flowchart shown in FIG. The receivingcircuit unit 17 of thewireless slave device 3 wirelessly receives a signal via the antenna 16 (step S11). The electric fieldstrength measuring unit 18 measures the electric field strength of the received signal and outputs the measured value to the control circuit unit 22 (step S12). Themessage analysis unit 21 analyzes the message of the received signal and determines whether it is a test signal (step S13). If the received signal is a test signal, thecontrol circuit unit 22 compares the measured value of the electric field strength with the threshold value set in the threshold value setting unit 24 (step S14). When the measured value of the electric field strength is smaller than the threshold value, an error is notified to the notification unit 25 (step S15), and the communication is terminated (step S17). If the received signal is not a test signal in step S13 or if the measured value of the electric field strength is larger than the threshold value in step S14, thecontrol circuit unit 22 performs normal communication (step S16) and ends the communication. (Step S17).

このように、本発明の実施例1に係る無線通信装置及び無線通信システムは、無線受信した信号がテスト信号であると判断されたときに、電界強度測定部で測定された電界強度と、しきい値設定部に設定されたしきい値とを制御回路部が比較する。電界強度の測定値がしきい値よりも大きいときは通常の通信を行い、測定値がしきい値よりも小さいときはエラー報知するので、無線子機3及び無線親機1を新規に設置する場合、設置後の電波状況を考慮したテスト通信を容易に行うことができる。このため、設置後の家具の配置変更による電波状況の変化や、昼夜での電波状況の変化や、フェージング等が発生した場合でもより高い通信品質の確保ができる。  As described above, the wireless communication device and the wireless communication system according to the first embodiment of the present invention use the electric field strength measured by the electric field strength measuring unit when the wirelessly received signal is determined to be a test signal. The control circuit unit compares the threshold value set in the threshold value setting unit. When the measured value of the electric field strength is larger than the threshold value, normal communication is performed, and when the measured value is smaller than the threshold value, an error is notified, so thewireless slave device 3 and the wireless master device 1 are newly installed.
