本発明によれば、複数のセンサーユニットが同期をとって計測を行うことができるデータロガーを提供できる。
According to the present invention, it is possible to provide a data logger capable of performing measurements in synchronization with a plurality of sensor units.
以下、図１を参照して、本発明の一実施形態によるデータロガー１００について説明する。
Hereinafter, the data logger 100 according to the embodiment of the present invention will be described with reference to FIG.
データロガー１００は、コントロールユニット１１０と、複数のセンサーユニット１３０ａ～１３０ｄとを主に備える。
The data logger 100 mainly includes a control unit 110 and a plurality of sensor units 130a to 130d.
コントロールユニット１１０は、同期信号生成部１１１と、電源１１２とを主に備える。同期信号生成部１１１は、同期信号を生成する。同期信号の周波数は、例えば４００Ｈｚである。電源１１２は、電池又は交流電源をデータロガー１００に適した直流電圧に変換した電源であって、電源線１１２ａを介してコントロールユニット１１０が備える各部材に電力を供給する。
The control unit 110 mainly includes a synchronization signal generation unit 111 and a power supply 112. The synchronization signal generation unit 111 generates a synchronization signal. The frequency of the synchronization signal is, for example, 400 Hz. The power supply 112 is a power supply obtained by converting a battery or an AC power supply into a DC voltage suitable for the data logger 100, and supplies power to each member included in the control unit 110 via a power supply line 112a.
複数のセンサーユニット１３０ａ～１３０ｄは、センサー１３１ａ～１３１ｄと、記録部１３２ａ～１３２ｄと、電源接続端子１３４ｃとを主に備える。センサー１３１ａ～１３１ｄは、例えば加速度センサ、ジャイロセンサ、及び／又は温度センサなどであって、測定データを出力する。測定データは、いわゆるＲＡＷデータであって、センサー配線１３３ａ～１３３ｄを介して記録部１３２ａ～１３２ｄに送信される。記録部１３２ａ～１３２ｄは、例えば着脱可能なメモリカードであって、センサー１３１ａ～１３１ｄが出力した測定データを記録する。電源接続端子１３４ｃには、電源ユニット１１３が接続されうる。電源ユニット１１３は、電池又は交流電源である。
The plurality of sensor units 130a to 130d mainly include sensors 131a to 131d, recording units 132a to 132d, and a power supply connection terminal 134c. The sensors 131a to 131d are, for example, an acceleration sensor, a gyro sensor, and / or a temperature sensor, and output measurement data. The measurement data is so-called RAW data and is transmitted to the recording units 132a to 132d via the sensor wirings 133a to 133d. The recording units 132a to 132d are, for example, removable memory cards, and record the measurement data output by the sensors 131a to 131d. A power supply unit 113 may be connected to the power supply connection terminal 134c. The power supply unit 113 is a battery or an AC power source.
コントロールユニット１１０と複数のセンサーユニット１３０ａ～１３０ｄとは、配線１２０ａ～１２０ｄを介して直列に接続、すなわちデイジーチェーンを作るように接続される。センサーユニット１３０ａは、コントロールユニット１１０から配線１２０ａを介して受信した同期信号及び電力を、配線１２０ｂを介してセンサーユニット１３０ｂに伝送する。そして、次のセンサーユニット１３０ｂは、センサーユニット１３０ａから受信した同期信号及び電力を、次の配線を介してセンサーユニット１３０ｃに伝送する。これを繰り返して、同期信号及び電力が、複数のセンサーユニット１３０ａ～１３０ｄに配線１２０ａ～１２０ｄを介して順に伝送される。
The control unit 110 and the plurality of sensor units 130a to 130d are connected in series via wirings 120a to 120d, that is, connected so as to form a daisy chain. The sensor unit 130a transmits the synchronization signal and electric power received from the control unit 110 via the wiring 120a to the sensor unit 130b via the wiring 120b. Then, the next sensor unit 130b transmits the synchronization signal and the electric power received from the sensor unit 130a to the sensor unit 130c via the next wiring. By repeating this, the synchronization signal and the electric power are sequentially transmitted to the plurality of sensor units 130a to 130d via the wirings 120a to 120d.
複数のセンサーユニット１３０ａ～１３０ｄは、コントロールユニット１１０からの電力を受けて動作するとともに、コントロールユニット１１０からの同期信号に同期して、センサー１３１ａ～１３１ｄから測定データを受信し、取得タイミング情報とともに、記録部１３２ａ～１３２ｄに記憶させる。取得タイミング情報は、測定データを取得した時を特定する情報であって、例えば測定開始からの積算クロック数などである。
The plurality of sensor units 130a to 130d operate by receiving electric power from the control unit 110, receive measurement data from the sensors 131a to 131d in synchronization with the synchronization signal from the control unit 110, and together with the acquisition timing information. It is stored in the recording units 132a to 132d. The acquisition timing information is information that identifies when the measurement data is acquired, such as the number of integrated clocks from the start of measurement.
センサーユニット１３０ｃの電源接続端子１３４ｃには、電源ユニット１１３が接続される。電源ユニット１１３は、電源線１１３ｃを介して、センサーユニット１３０ｃに電力を供給する。そして、電源ユニット１１３から電力を受けたセンサーユニット１３０ｃは、センサーユニット１３０ｃよりもコントロールユニット１１０から離れているセンサーユニット１３０ｄに電力を供給する。つまり、電源ユニット１１３は、センサーユニット１３０ｃ以遠のセンサーユニットに電力を供給する。一般に、複数のセンサーユニット１３０ａ～１３０ｄの数が多い場合、コントロールユニット１１０から離れているセンサーユニットにコントロールユニット１１０から電力を供給できず、センサーユニットの動作が不安定にある場合がある。このような場合であっても、センサーユニット１３０ｃに電源ユニット１１３を接続して直接電力を供給すれば、そのセンサーユニット１３０ｃ以遠のセンサーユニットに電力を供給し、安定動作させることができる。
The power supply unit 113 is connected to the power supply connection terminal 134c of the sensor unit 130c. The power supply unit 113 supplies electric power to the sensor unit 130c via the power supply line 113c. Then, the sensor unit 130c that receives the electric power from the power supply unit 113 supplies the electric power to the sensor unit 130d that is farther from the control unit 110 than the sensor unit 130c. That is, the power supply unit 113 supplies power to the sensor unit beyond the sensor unit 130c. Generally, when the number of a plurality of sensor units 130a to 130d is large, power cannot be supplied from the control unit 110 to the sensor unit away from the control unit 110, and the operation of the sensor unit may be unstable. Even in such a case, if the power supply unit 113 is connected to the sensor unit 130c and the power is directly supplied, the power can be supplied to the sensor units beyond the sensor unit 130c and stable operation can be performed.
次に、データロガー１００を用いた測定手段について説明する。所定のタイミングで、コントロールユニット１１０が複数のセンサーユニット１３０ａ～１３０ｄに測定開始の信号を送信した後、複数のセンサーユニット１３０ａ～１３０ｄに４００Ｈｚの同期信号を送信する。この間、コントロールユニット１１０は複数のセンサーユニット１３０ａ～１３０ｄに電力を送信している。測定開始の信号を受信した複数のセンサーユニット１３０ａ～１３０ｄは、同期信号に同期して、センサー１３１ａ～１３１ｄから測定データを受信し、記録部１３２ａ～１３２ｄに取得タイミング情報とともに記憶させる。これを所定期間反復した後、コントロールユニット１１０が測定終了の信号を送信し、複数のセンサーユニット１３０ａ～１３０ｄは測定を終了する。そして、複数のセンサーユニット１３０ａ～１３０ｄが備える記録部１３２ａ～１３２ｄから測定データ及び取得タイミング情報を回収する。これにより、測定を終了する。
Next, the measuring means using the data logger 100 will be described. At a predetermined timing, the control unit 110 transmits a measurement start signal to the plurality of sensor units 130a to 130d, and then transmits a 400 Hz synchronization signal to the plurality of sensor units 130a to 130d. During this time, the control unit 110 transmits electric power to the plurality of sensor units 130a to 130d. The plurality of sensor units 130a to 130d that have received the measurement start signal receive the measurement data from the sensors 131a to 131d in synchronization with the synchronization signal, and store the measurement data in the recording units 132a to 132d together with the acquisition timing information. After repeating this for a predetermined period of time, the control unit 110 transmits a measurement end signal, and the plurality of sensor units 130a to 130d end the measurement. Then, the measurement data and the acquisition timing information are collected from the recording units 132a to 132d included in the plurality of sensor units 130a to 130d. This ends the measurement.
本実施形態によれば、容易に複数のセンサーユニットが同期をとって計測を行うことができるデータロガーを得る。また、全てのセンサーユニットが同期信号に従って測定を行うため、同時に複数の測定データを得ることができる。また、複数のセンサーユニットにコントロールユニット１１０から電力を供給可能であるため、センサーユニット各々に個別に電力を直接供給する必要がない。また、コントロールユニット１１０と複数のセンサーユニットとを直列に接続するため、配線数を低減できる。さらに、コントロールユニット１１０からでなく、電源ユニット１１３からセンサーユニットに直接電力を供給することにより、例えば１００ｍや１ｋｍなど、長距離に渡ってセンサーユニットを繋げて延ばすことができ、これにより、橋、建築物、プラントなどの測定に使用できる。例えば、特許文献１に記載されているような無線式のセンサーユニットでは、親機と子機が通信範囲内になければデータを親機が受信できないが、本実施形態のようにセンサーユニットを直列に繋げれば、距離の制限を受けることなく、測定を行うことができる。
According to this embodiment, a data logger capable of easily synchronizing a plurality of sensor units to perform measurement is obtained. Further, since all the sensor units perform measurement according to the synchronization signal, a plurality of measurement data can be obtained at the same time. Further, since the power can be supplied to the plurality of sensor units from the control unit 110, it is not necessary to directly supply the power to each of the sensor units individually. Further, since the control unit 110 and the plurality of sensor units are connected in series, the number of wirings can be reduced. Further, by supplying power directly to the sensor unit from the power supply unit 113 instead of from the control unit 110, the sensor unit can be connected and extended over a long distance such as 100 m or 1 km, whereby the bridge, It can be used for measurement of buildings, plants, etc. For example, in a wireless sensor unit as described in Patent Document 1, the master unit cannot receive data unless the master unit and the slave unit are within the communication range, but the sensor units are connected in series as in the present embodiment. If you connect to, you can measure without being limited by the distance.
なお、センサーユニットの数が少ない場合、電源ユニット１１３は設けられなくてもよい。また、センサーユニット１３０ａ～１３０ｄは、電源接続端子１３４ｃを備えなくてもよい。
If the number of sensor units is small, the power supply unit 113 may not be provided. Further, the sensor units 130a to 130d do not have to include the power supply connection terminal 134c.
なお、電源１１２は、図示されるように電源線を介してコントロールユニット１１０に接続されなくてもよく、コントロールユニット１１０内部に格納されてもよい。
The power supply 112 may not be connected to the control unit 110 via a power supply line as shown in the figure, or may be stored inside the control unit 110.
なお、電源ユニット１１３が、センサーユニット１３０ｃ以遠のセンサーユニットに電力を供給すると説明したが、センサーユニット１３０ｃよりもコントロールユニット１１０に近いセンサーユニットに電力を供給してもよい。
Although it has been explained that the power supply unit 113 supplies electric power to the sensor unit beyond the sensor unit 130c, the electric power may be supplied to the sensor unit closer to the control unit 110 than the sensor unit 130c.
