速度信号送信装置、速度信号受信装置、動揺測定システムSpeed signal transmitting device, speed signal receiving device, oscillation measurement system
　本発明は、鉄道車両等の移動体に備えられる速度発電機からの速度信号を、無線で送受信する速度信号送受信装置及びそれらを含む動揺測定システムに関する。 The present invention relates to a speed signal transmission / reception apparatus that wirelessly transmits and receives a speed signal from a speed generator provided in a moving body such as a railway vehicle, and an oscillation measurement system including them.
　移動体、特に鉄道車両においては、輸送品質を表す指標として、振動によって生じる加速度、すなわち動揺値は大切な指標であり、動揺値が大きい位置を特定することは、事故を未然に防ぐためにも極めて重要である。このため鉄道事業者は、定期的に動揺値を計測して動揺値の大きな位置を特定し、それを元に線路の管理をおこなっている。 In moving objects, especially railway vehicles, the acceleration caused by vibration, that is, the shaking value, is an important indicator as an indicator of transport quality, and specifying a position where the shaking value is large is extremely important to prevent accidents. is important. For this reason, railway operators regularly measure the oscillation value, identify the position where the oscillation value is large, and manage the track based on this.
　従来、鉄道車両の位置を特定するためには、線路上に設けられたキロポストと呼ばれる標識を目視で確認する方法や、車軸の回転を測定して速度を算出しそれを元に位置を確認する方法が用いられている（例えば、特開２００１－２８７６４７号公報参照）。 Conventionally, in order to identify the position of a railway vehicle, a method of visually confirming a sign called a kilopost provided on a track, or measuring the speed by measuring the rotation of an axle, and confirming the position based on it A method is used (see, for example, Japanese Patent Application Laid-Open No. 2001-287647).
　図７は、従来の動揺測定の方法を説明する概念図である。動揺測定装置３００の操作者は、図７（Ａ）のように、車両７０に動揺測定装置３００を設置して、動揺値を測定する。このとき動揺値の大きな地点が線路上のどの場所であるかを特定するために、動揺測定装置の操作者が、目視でキロポスト２９５を確認し、動揺測定装置へ、随時、入力する方法が用いられている。またより細かく車両の位置を特定するために、速度発電機２９０による速度測定を同時に行う方法も用いられている。すなわち、車両７０の設備として設けられている速度発電機２９０から速度信号を取得し、動揺測定装置３００で動揺値と同時測定することで位置を特定する。 FIG. 7 is a conceptual diagram illustrating a conventional method for measuring shaking. As shown in FIG. 7A, the operator of the shake measurement device 300 installs the shake measurement device 300 in the vehicle 70 and measures the shake value. At this time, in order to identify the location on the track where the large fluctuation value is located, the operator of the vibration measurement device visually confirms the kilopost 295 and inputs to the vibration measurement device as needed. It has been. In order to specify the position of the vehicle more finely, a method of simultaneously measuring the speed by the speed generator 290 is also used. That is, a speed signal is acquired from a speed generator 290 provided as a facility of the vehicle 70, and the position is specified by simultaneously measuring the fluctuation value with the fluctuation measuring device 300.
　図７（Ｂ）に、速度発電機２９０と、従来の動揺測定装置３００の接続方法を示す。速度発電機２９０（図示省略）からの速度信号は、車両７０の車室内に設けられた速度発電機接続箱３２０から、コネクタを介してケーブル３１０によって動揺測定装置３００に送られる。操作者は、動揺測定装置３００において取得した時刻、速度、位置（キロ程）、動揺値を、記録用紙３３０に出力し、さらにコンパクトフラッシュ（登録商標）等の記憶媒体に記録して、測定後にＰＣ（パーソナルコンピュータ）等で解析を行う。 FIG. 7B shows a connection method between the speed generator 290 and the conventional fluctuation measuring apparatus 300. A speed signal from the speed generator 290 (not shown) is sent from the speed generator connection box 320 provided in the passenger compartment of the vehicle 70 to the sway measuring device 300 through the connector 310 via the cable 310. The operator outputs the time, speed, position (about kilometer), and shaking value acquired by the shaking measuring device 300 to the recording paper 330, and further records it on a storage medium such as a compact flash (registered trademark). Analysis is performed with a PC (personal computer) or the like.

　しかし速度発電機２９０で生成する速度信号は、一般に１００Ｖ以上となることも多く、また鉄道車両７０には、高電圧を発生する装置類が多数設置されているため、電磁波ノイズも多い環境でもある。そこでケーブル３１０は、感電事故を防ぎ、ノイズにも強くするために、二重絶縁ケーブル等を用いることが多い。しかしその種のケーブルは、重く、また取り扱いも面倒である。また複数の動揺測定装置を、複数の車両にまたがって設置して同時に測定を行うことも困難である。 However, the speed signal generated by the speed generator 290 is generally 100 V or more in many cases, and the railway vehicle 70 is equipped with many devices that generate high voltage, so that it is also an environment with a lot of electromagnetic noise. . Therefore, the cable 310 often uses a double insulated cable or the like in order to prevent an electric shock accident and to be strong against noise. However, these types of cables are heavy and cumbersome to handle. It is also difficult to install a plurality of sway measuring devices across a plurality of vehicles and perform measurement simultaneously.
　本発明は、上記課題を鑑みてなされたものであり、既存の車両設備である速度発電機等の資産を利用しつつ、動揺測定装置を設置する場所の制約が無く、且つ、複数の動揺測定装置による同時測定も可能な動揺測定システムを提供する。 The present invention has been made in view of the above-mentioned problems, and there are no restrictions on the place where the vibration measurement device is installed while utilizing assets such as a speed generator that is an existing vehicle facility, and a plurality of vibration measurements are performed.

For this reason, the present invention has a remarkably excellent effect of making a heavy and long cable which has been essential until now unnecessary.

For this reason, a measuring device that uses a speed signal has a restriction that it needs to perform measurement in the vicinity of the speed generator connection box, which is an exit of the speed generator signal, or use a long cable.

　次に、上記した実施の形態の動作を説明する。 Next, the operation of the above embodiment will be described.
　図３（Ａ）は、速度発電機５０が生成する速度信号の電圧の時間変化である。速度信号は、車両が備える車軸の回転に対応したサイン波様の波形である。速度信号は、変換部１１０でパルス信号に変換されて、電気的絶縁のために絶縁部１００に入力される。本第一実施形態においては、変換部１１０はコンパレータであり、その参照電圧Ｖｒｅｆより高い電圧になるときに、パルス信号はハイレベルとなる。図３（Ｂ）は、速度信号送信装置１０が備える絶縁部１００の出力である速度情報信号の時間変化である。 FIG. 3 (A) shows the change over time of the voltage of the speed signal generated by the speed generator 50. The speed signal is a sine wave-like waveform corresponding to the rotation of the axle included in the vehicle. The speed signal is converted into a pulse signal by the conversion unit 110 and input to the insulation unit 100 for electrical insulation. In the first embodiment, the conversion unit 110 is a comparator, and when the voltage becomes higher than the reference voltage Vref, the pulse signal becomes a high level. FIG. 3B is a time change of the speed information signal that is an output of the insulating unit 100 included in the speed signal transmitting apparatus 10.
　図３（Ｃ）は、無線送信処理部１２０が備える変調回路が、振幅変調回路である場合において、速度信号送信装置１０が送信する無線信号の時間変化である。該無線信号を受信する速度信号受信装置２０は、無線受信処理部１３０で受信して、復調回路１３５で復調して図２（Ｂ）で示す速度情報信号を得る。そして波形復元部１４０で速度信号と同等の波形である復元波形を復元して、動揺測定装置３０に送る。 FIG. 3C shows a time change of a radio signal transmitted by the speed signal transmission device 10 when the modulation circuit included in the radio transmission processing unit 120 is an amplitude modulation circuit. The speed signal receiving apparatus 20 that receives the radio signal is received by the radio reception processing unit 130 and demodulated by the demodulation circuit 135 to obtain a speed information signal shown in FIG. Then, the waveform restoration unit 140 restores a restored waveform, which is a waveform equivalent to the speed signal, and sends the restored waveform to the fluctuation measuring device 30.
　図３（Ｄ）は、車両内で使用される動揺測定システム１の動作説明図である。車両７０内に設置された速度発電機５０で生成される速度信号から取得した速度情報を、速度信号送信装置１０は、速度信号受信装置２０に無線送信する。速度信号受信装置２０は、その無線信号を受信して、速度情報を動揺測定装置３０に送る。速度信号受信装置２０と動揺測定装置３０の組み合わせは、複数あっても良い。 FIG. 3D is an operation explanatory diagram of the sway measurement system 1 used in the vehicle. The speed signal transmission device 10 wirelessly transmits the speed information acquired from the speed signal generated by the speed generator 50 installed in the vehicle 70 to the speed signal reception device 20. The speed signal receiving device 20 receives the radio signal and sends speed information to the motion measuring device 30. There may be a plurality of combinations of the speed signal receiving device 20 and the fluctuation measuring device 30.
　本第一実施形態に係る速度信号送信装置１０は、車両設備として備えられている速度発電機５０から速度信号を取得できる送信装置側コネクタ１７を有するため、車両７０の速度を測定するために既存の設備を利用でき、安価であり、またこれまで蓄積してきたデータとの比較もし易い。また絶縁部１００を有しているので、高電圧ノイズが生じがちな鉄道車両設備という特殊な環境下において、適切に信号を取得できる。また逆に、本発明に係る速度信号送信装置１０から、速度発電機５０に接続するＡＴＳ等の他の車両設備へ、電気的なノイズや故障の影響を与えることも防ぐことができる。 Since the speed signal transmission device 10 according to the first embodiment includes the transmission device side connector 17 that can acquire a speed signal from the speed generator 50 provided as a vehicle facility, the speed signal transmission device 10 is an existing device for measuring the speed of the vehicle 70. These facilities can be used, are inexpensive, and are easy to compare with the data accumulated so far. Moreover, since it has the insulation part 100, a signal can be acquired appropriately in the special environment of railroad vehicle equipment in which high voltage noise tends to occur. Conversely, it is possible to prevent electrical noise and failure from being affected by the speed signal transmitting apparatus 10 according to the present invention to other vehicle equipment such as ATS connected to the speed generator 50.
　さらに絶縁部１００の下流には、速度情報を含んだ無線信号を送信する無線送信処理部１２０を備えているので、速度信号の情報である速度情報を無線で送信することができ、速度情報を取得するためにこれまで必須であった重く長いケーブルを不要のものとする著しく優れた効果を奏する。 Further, since the wireless transmission processing unit 120 that transmits the wireless signal including the speed information is provided downstream of the insulating unit 100, the speed information that is the information of the speed signal can be transmitted wirelessly. There is a remarkable effect of making a heavy and long cable that has been essential for acquisition unnecessary.
　速度信号送信装置１０は、速度情報を含む無線信号を、振幅変調方式で変調した信号として送信できるので、複数の車両間にまたがるような距離でも速度情報信号を授受できるという極めて優れた効果を奏する。 The speed signal transmission device 10 can transmit a radio signal including speed information as a signal modulated by an amplitude modulation method, and thus has an extremely excellent effect that the speed information signal can be transmitted and received even at a distance spanning a plurality of vehicles. .
　従来、速度発電機５０からの速度信号は、速度発電機５０と電気的に接続されたケーブルを引き回して利用されていた。そのため速度信号を利用する測定装置は、速度発電機５０の信号の出口である速度発電機接続箱４０の近傍において測定を行うか、長大なケーブルを使用しなければならないという制約があった。速度信号受信装置２０によれば、速度信号送信装置１０から移動体の速度情報を含む無線信号を受信する無線受信処理部１３０と、無線信号を復調して得られた速度情報信号を、前記速度信号と同等の波形である復元波形に復元する波形復元部１４０を有するので、速度発電機５０の近傍でなくても、速度発電機５０が生成する速度信号と同等の信号を利用することができるという極めて優れた効果を奏する。 Conventionally, the speed signal from the speed generator 50 has been used by routing a cable electrically connected to the speed generator 50. For this reason, the measuring device using the speed signal has a restriction that it needs to perform measurement in the vicinity of the speed generator connection box 40 that is an output of the signal of the speed generator 50 or use a long cable. According to the speed signal receiving device 20, the wireless reception processing unit 130 that receives the wireless signal including the speed information of the moving body from the speed signal transmitting device 10, and the speed information signal obtained by demodulating the wireless signal are used as the speed signal. Since the waveform restoration unit 140 that restores the restored waveform, which is a waveform equivalent to the signal, is provided, a signal equivalent to the speed signal generated by the speed generator 50 can be used even if it is not in the vicinity of the speed generator 50. There is an extremely excellent effect.
　また波形復元部１４０により復元された復元波形を送るための受信装置側コネクタ２７を有するので、速度信号を利用することを前提とした既存の測定装置が、復元された速度信号を容易に利用できるという利点を有する。たとえば鉄道事業者がすでに有している、速度信号を直接速度発電機５０に接続して使用する従来の動揺測定装置を、そのまま利用することができるので、費用面でも大きな利点がある。 In addition, since the receiving device side connector 27 for sending the restored waveform restored by the waveform restoring unit 140 is provided, the existing measuring device based on the use of the speed signal can easily use the restored velocity signal. Has the advantage. For example, a conventional vibration measurement device that is already used by a railway operator and that is used by directly connecting a speed signal to the speed generator 50 can be used as it is, which is a great advantage in terms of cost.
　なお本第一実施形態においては、動揺測定装置３０が速度信号と同等の波形を利用する態様を説明したが、速度信号や速度情報信号の立ち上がりエッジを検出して、周波数を算出し、その数値を速度信号送信装置１０から送信し、速度信号受信装置２０で受信して利用しても良い。また速度信号受信装置２０において波形復元部１４０を省略して、復調された速度情報信号の立ち上がりエッジを検出して周波数を算出しても良い。これらの変形実施例の詳細な構成等については、周知技術なので記載を省略する。 In the first embodiment, the aspect in which the fluctuation measuring device 30 uses a waveform equivalent to the speed signal has been described. However, the rising edge of the speed signal or the speed information signal is detected, the frequency is calculated, and the numerical value is calculated. May be transmitted from the speed signal transmitter 10 and received by the speed signal receiver 20 for use. Further, in the speed signal receiving apparatus 20, the waveform restoration unit 140 may be omitted, and the rising edge of the demodulated speed information signal may be detected to calculate the frequency. Since the detailed configuration and the like of these modified embodiments are well-known techniques, description thereof is omitted.
　以上のような構成を有する動揺測定システム１により、既存の車両設備である速度発電機等の資産を利用しつつ、動揺測定装置３０を設置する場所の制約が無く、且つ、複数の動揺測定装置による同時測定も可能な動揺測定システムが実現される。 With the fluctuation measurement system 1 having the above-described configuration, there is no restriction on the place where the fluctuation measurement device 30 is installed while utilizing assets such as a speed generator that is an existing vehicle facility, and a plurality of fluctuation measurement devices. A motion measurement system capable of simultaneous measurement by using the above is realized.
　図４は本発明の第二実施形態に係る動揺測定システム１の説明図である。図４（Ａ）は、中継式速度信号送信部２７０を備える速度信号受信装置２２の構成図である。速度信号受信装置２２は、中継式速度信号送信部２７０を備え、無線受信処理部１３０が受信した速度情報を含む無線信号を増幅して、再び無線送信する。その他の構成は、第一実施形態における速度信号受信装置２０と同じなので記載を省略する。 FIG. 4 is an explanatory diagram of the fluctuation measurement system 1 according to the second embodiment of the present invention. FIG. 4A is a configuration diagram of the speed signal receiving device 22 including the relay type speed signal transmitting unit 270. The speed signal receiving device 22 includes a relay type speed signal transmitting unit 270, amplifies a radio signal including speed information received by the radio reception processing unit 130, and wirelessly transmits again. Since other configurations are the same as those of the speed signal receiving apparatus 20 in the first embodiment, description thereof is omitted.
　図４（Ｂ）は、中継式速度信号送信部２７０を備える速度信号受信装置２２を接続した第一の動揺測定装置２５０の動作説明図と構成図である。速度信号受信装置２２は、中継式速度信号送信部２７０を備え、速度信号送信装置１０から受信した無線信号を増幅して中継し、再び送信する。そして速度信号受信装置２０を接続した第二の動揺測定装置２６０が、無線信号を受信することで、速度発電機５０の生成する速度信号が有する速度情報を利用可能になる。 FIG. 4B is an operation explanatory diagram and a configuration diagram of the first fluctuation measuring device 250 to which the speed signal receiving device 22 including the relay type speed signal transmitting unit 270 is connected. The speed signal receiving device 22 includes a relay type speed signal transmitting unit 270, amplifies and relays the radio signal received from the speed signal transmitting device 10, and transmits again. The second fluctuation measuring device 260 connected to the speed signal receiving device 20 receives the radio signal, so that the speed information included in the speed signal generated by the speed generator 50 can be used.
　すなわち、第二実施形態に係る動揺測定システム１は、中継式速度信号送信部２７０を有する速度信号受信装置２２を接続している第一の速度信号受信装置と、速度信号受信装置２０を接続している第二の速度信号受信装置と、速度信号受信装置に各々接続される複数の前記動揺測定装置と、を備え、速度信号送信装置から無線で送信されて速度信号受信装置２２で受信される無線信号を、中継式速度信号送信部２７０により、速度信号受信装置２０に転送することを特徴とする。 That is, the fluctuation measurement system 1 according to the second embodiment connects the speed signal receiver 20 to the first speed signal receiver connected to the speed signal receiver 22 having the relay type speed signal transmitter 270. A second speed signal receiving device, and a plurality of the motion measurement devices connected to the speed signal receiving device, respectively, are transmitted wirelessly from the speed signal transmitting device and received by the speed signal receiving device 22 The wireless signal is transferred to the speed signal receiver 20 by the relay type speed signal transmitter 270.
　中継式速度信号送信部を有する速度信号受信装置２２が接続された第一の動揺測定装置２５０は、従来の動揺測定装置３０でよく、第一の動揺測定装置２５０全体の制御を行う制御部１５０と、記録装置２００と、中継式速度信号送信部を有する速度信号受信装置２２からの信号をカウントするカウンタ部２４０と、付帯情報等を入力するための入力手段１７０と、動揺値（加速度）を測定する動揺測定手段１８０と、記録用紙に動揺波形等の印刷をおこなうプリンタやモニタ等の出力手段１９０と、バス１６０を備える。 The first fluctuation measuring device 250 to which the speed signal receiving device 22 having a relay type velocity signal transmitting unit is connected may be the conventional fluctuation measuring device 30 and the control unit 150 that controls the entire first fluctuation measuring device 250. A counter unit 240 that counts signals from the recording device 200, a speed signal receiving device 22 having a relay type speed signal transmitting unit, an input unit 170 for inputting incidental information, and a fluctuation value (acceleration). An oscillation measuring means 180 for measuring, an output means 190 such as a printer or a monitor for printing an oscillation waveform on a recording sheet, and a bus 160 are provided.
　制御部１５０はＣＰＵ１５２、ＲＡＭ１５４およびＲＯＭ１５６などから構成され、各種制御を実行する。ＣＰＵはいわゆる中央演算処理装置であり、各種プログラムが実行されて様々な機能を実現する。ＲＡＭはＣＰＵの作業領域、記憶領域として使用され、ＲＯＭはＣＰＵで実行されるオペレーティングシステムやプログラムを記憶する。 The control unit 150 includes a CPU 152, a RAM 154, a ROM 156, and the like, and executes various controls. The CPU is a so-called central processing unit, and executes various programs to realize various functions. The RAM is used as a work area and a storage area of the CPU, and the ROM stores an operating system and programs executed by the CPU.
　記録装置２００は、プログラム等を記録するプログラム等記録領域２１０と、動揺値を記録する動揺値記録領域２２０と、速度信号受信装置２０から取得した速度情報を記録する速度情報記録領域２３０を備える。 The recording apparatus 200 includes a program recording area 210 for recording a program, a fluctuation value recording area 220 for recording a fluctuation value, and a speed information recording area 230 for recording speed information acquired from the speed signal receiving apparatus 20.
　いずれの無線通信規格についても、信号の授受が可能な距離は有限である。金属部分の多い鉄道車両内においては、無線通信が可能な距離は限られており、特に複数の車両間での通信は簡単ではない。 For any wireless communication standard, the distance that signals can be exchanged is limited. In a railway vehicle having a lot of metal parts, the distance at which wireless communication is possible is limited, and in particular, communication between a plurality of vehicles is not easy.
　本第二実施形態に係る動揺測定システム１によれば、一度受信した無線信号を、増幅して再び中継送信できる中継式速度信号送信部２７０を、速度信号受信装置２２が備えることで、速度信号を速度発電機５０が設置された車両以外の車両や距離の離れた場所でも利
用することができるようになるという優れた効果を奏する。 According to the fluctuation measurement system 1 according to the second embodiment, the speed signal receiver 22 includes the relay-type speed signal transmission unit 270 that can amplify a radio signal that has been received once and relay-transmit it again. Can be used even in a vehicle other than the vehicle in which the speed generator 50 is installed or in a place away from the distance.
　移動体の速度情報を含む無線信号を送信する速度信号送信装置１０と、該無線信号を受信する速度信号受信装置２０と、該速度信号受信装置２０に接続されて移動体の動揺測定を行う動揺測定装置３０を、動揺測定システム１が備えているので、車両７０内での速度発電機５０の設置場所に制約されずに、本動揺測定システム１だけで、速度情報と動揺値を略同時に取得できるシステムを構築できるという極めて優れた効果を奏する。 A speed signal transmitting apparatus 10 that transmits a radio signal including speed information of a moving body, a speed signal receiving apparatus 20 that receives the radio signal, and a shake that is connected to the speed signal receiving apparatus 20 and performs motion measurement of the moving body Since the measurement device 30 is provided with the measurement device 30, the velocity information and the oscillation value can be acquired almost simultaneously only by the actual oscillation measurement system 1 without being restricted by the installation location of the speed generator 50 in the vehicle 70. It has an extremely excellent effect of being able to build a system that can.
　また一つの速度発電機５０の速度信号を中継接続することで、複数の動揺測定装置で同じ速度信号を使用して動揺測定をすることが可能になるという優れた効果を奏する。 In addition, by connecting the speed signals of one speed generator 50, it is possible to perform the vibration measurement by using the same speed signal by a plurality of vibration measuring devices.
　なお、鉄道事業者がすでに有している、速発電機に直接接続して使用する従来の動揺測定装置を、そのまま利用することができるので、費用面でも大きな利点がある。 In addition, since the conventional vibration measurement device already connected to the speed generator and used by the railway operator can be used as it is, there is a great cost advantage.
　図５は、本発明の第三実施形態に係る無線受信処理部１３０を備えた動揺測定装置２８５の構成図である。前述の第一実施形態および第二実施形態において、動揺測定装置３０は、速度情報を含む無線信号を受信する機能が備えられていない。これに対して本実施形態に係る無線受信処理部１３０を備えた動揺測定装置２８５は、無線受信処理部１３０、無線信号を速度情報信号へ復調する復調回路１３５等が備えられている。その他の構成は、図４（Ｂ）に記載した動揺測定装置３０と同様なので記載を省略する。 FIG. 5 is a configuration diagram of the fluctuation measuring device 285 including the wireless reception processing unit 130 according to the third embodiment of the present invention. In the first embodiment and the second embodiment described above, the fluctuation measuring device 30 does not have a function of receiving a radio signal including speed information. On the other hand, the fluctuation measuring device 285 including the radio reception processing unit 130 according to the present embodiment includes the radio reception processing unit 130, a demodulation circuit 135 that demodulates the radio signal into a speed information signal, and the like. The other configuration is the same as that of the fluctuation measurement device 30 described in FIG.
　本第三実施形態に係る動揺測定装置２８５自体が、速度情報を含む無線信号を送信する速度信号送信装置１０から、該無線信号を受信する無線受信処理部１３０等を有するので、移動体の速度と動揺値を同時に測定することができる。従って、特別に速度信号受信装置を用意せずとも、車両内での速度発電機５０の設置場所に制約されずに、速度情報と動揺値を取得できるという優れた効果を奏する。 The fluctuation measuring device 285 itself according to the third embodiment includes the wireless reception processing unit 130 that receives the wireless signal from the speed signal transmitting device 10 that transmits the wireless signal including the speed information. And shake value can be measured simultaneously. Therefore, even if a speed signal receiving device is not specially prepared, the speed information and the shake value can be acquired without being restricted by the installation location of the speed generator 50 in the vehicle.
　なお制御部１５０が、取得された速度情報に基づいてキロ程を算出するキロ程算出をおこなっても良い。すなわち無線受信処理部１３０を備えた動揺測定装置２８５は、速度情報に基づいてキロ程を算出するキロ程算出部（図示省略）をさらに備えて良い。 The control unit 150 may perform a kilometer calculation that calculates a kilometer based on the acquired speed information. That is, the fluctuation measuring device 285 including the wireless reception processing unit 130 may further include a kilometer calculation unit (not shown) that calculates the kilometer based on the speed information.
　速度情報から所定の起点からの距離であるキロ程を算出するキロ程算出機能を備えることになるので、どの地点で大きな動揺値が測定されたかという位置特定が極めて容易になるという大きな効果を奏する。 Since it is equipped with a kilometer calculation function for calculating the kilometer distance from the predetermined starting point from the speed information, it has a great effect that it is very easy to specify the position where the large fluctuation value is measured at which point. .
　また速度情報を含む無線信号を送信する中継式速度信号送信部（図示省略）をさらに備えても良い。 Further, a relay type speed signal transmission unit (not shown) for transmitting a radio signal including speed information may be further provided.
　一度受信した無線信号を、増幅して再び中継送信できる中継式速度信号送信部２７０を、動揺測定装置２８５自体が備えるので、別に中継器等を用意しなくても、同一の速度信号を、速度発電機５０が設置された車両以外の車両や距離の離れた場所でも利用することができるようになるという優れた効果を奏する。 Since the fluctuation measuring device 285 itself includes a relay type speed signal transmitting unit 270 that can amplify a radio signal received once and relay-transmit again, the same speed signal can be transmitted without the need for a separate repeater or the like. There is an excellent effect that it can be used in a vehicle other than the vehicle in which the generator 50 is installed or in a place away from the distance.
　図６は、本発明の第四実施形態に係る動揺測定システム１の動作説明図である。動揺測定システム１は、中継可能な動揺測定装置２８０を複数備える。言い換えると、動揺測定システム１は、前述した第三実施形態に記載した速度情報を含む無線信号を中継して送信する中継式速度信号送信部を有する動揺測定装置を複数備える。 FIG. 6 is an operation explanatory diagram of the fluctuation measurement system 1 according to the fourth embodiment of the present invention. The fluctuation measurement system 1 includes a plurality of fluctuation measurement apparatuses 280 that can be relayed. In other words, the fluctuation measurement system 1 includes a plurality of fluctuation measurement apparatuses each having a relay type speed signal transmission unit that relays and transmits a radio signal including the speed information described in the third embodiment.
　本第四実施形態に係る動揺測定システム１によれば、一つの速度発電機５０の速度信号を中継接続することで、同じ速度信号を使用して、複数の動揺測定装置２８０で動揺測定をすることが可能になるという優れた効果を奏する。 According to the sway measurement system 1 according to the fourth embodiment, the sway measurement is performed by a plurality of sway measurement devices 280 using the same speed signal by relaying the speed signals of one speed generator 50. There is an excellent effect that it becomes possible.
　なお中継可能な動揺測定装置２８０の代わりに、本発明の第二実施形態の記載中で述べた、中継式速度信号送信部２７０を備える速度信号受信装置２２を接続した動揺測定装置３０を混在して使用してもよく、場合によっては中継機能の無い速度信号受信装置２０を混在させて使用しても良い。 Instead of the swayable measuring device 280 capable of relaying, the swaying measuring device 30 connected to the speed signal receiving device 22 including the relay type speed signal transmitting unit 270 described in the description of the second embodiment of the present invention is mixed. In some cases, the speed signal receivers 20 having no relay function may be used together.
　尚、本発明に係る速度信号送信装置、速度信号受信装置、動揺測定システムは、上記した実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。 The speed signal transmitting device, speed signal receiving device, and fluctuation measurement system according to the present invention are not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention. Of course.
　例えば変形実施例として、速度信号送信装置における無線送信処理部が、周波数変調をおこなう変調回路である周波数変調回路を備えても良い。速度情報を含む無線信号を、周波数変調方式で変調した信号として送信できるので、複数の車両間にまたがるような距離でも、比較的ノイズの影響の少ない状態で、速度情報を授受できるという極めて優れた効果を奏する。もちろんこの場合には、速度信号受信装置側に備える復調回路として、周波数変調された無線信号を復調できるものを用意すべきことは言うまでもない。 For example, as a modified embodiment, the wireless transmission processing unit in the speed signal transmission device may include a frequency modulation circuit that is a modulation circuit that performs frequency modulation. Wireless signals containing speed information can be transmitted as a signal modulated by the frequency modulation method, so it is extremely excellent that speed information can be sent and received with relatively little influence of noise even at distances that span multiple vehicles. There is an effect. Of course, in this case, it is needless to say that a demodulating circuit provided on the speed signal receiving device side should be prepared so as to demodulate a frequency-modulated radio signal.
　他の変形実施例としては、速度信号送信装置における無線送信処理部が、デジタル変調をおこなう変調回路であるデジタル変調回路を備えても良い。速度情報を含む無線信号を、デジタル変調方式で変調した信号として送信できるので、誤り訂正等の機能を利用して、正確に速度情報を授受できるという優れた効果を奏する。もちろんこの場合にも、速度信号受信装置側に備える復調回路として、デジタル変調された無線信号を復調できるものを用意すべきことは言うまでもない。使用する無線通信の規格としては、いわゆるＢｌｕｅｔｏｏｔｈ（登録商標）や、Ｗｉ－Ｆｉ（登録商標）といったものを使用しても良い。 As another modified embodiment, the wireless transmission processing unit in the speed signal transmission device may include a digital modulation circuit that is a modulation circuit that performs digital modulation. Since a radio signal including speed information can be transmitted as a signal modulated by a digital modulation method, an excellent effect is achieved in that speed information can be exchanged accurately using a function such as error correction. Of course, in this case as well, it is needless to say that a demodulating circuit provided on the speed signal receiving device side should be prepared so as to demodulate a digitally modulated radio signal. As a wireless communication standard to be used, a so-called Bluetooth (registered trademark) or Wi-Fi (registered trademark) may be used.
　なお周波数変調、デジタル変調の詳細な技術については周知技術であるため記載を省略する。 Note that the detailed technology of frequency modulation and digital modulation is a well-known technology and will not be described.
