Description
本発明は、燃料電池自動車（以下、「ＦＣＶ」という場合あり）に水素ガスを供給する燃料ガス供給装置（ディスペンサ）がＦＣＶの充填口（レセプタクル）に設けられた送信部から受け取る信号を模擬した模擬信号を発信する燃料ガス供給装置用模擬信号発信装置に関する。 The present invention simulates a signal received by a fuel gas supply device (dispenser) for supplying hydrogen gas to a fuel cell vehicle (hereinafter sometimes referred to as “FCV”) from a transmitter provided in a filling port (receptacle) of the FCV. The present invention relates to a simulation signal transmission device for a fuel gas supply device that transmits a simulation signal.
ＦＣＶの市場形成を目指し、基準・規格整備等の基盤整備が進められているが、なかでも水素ステーションにおいて安全で効率的な急速充填手順を規定する充填プロトコルの策定は重要な課題とされている。 Aiming to form the FCV market, standards and standards are being developed, but in particular, the establishment of a filling protocol that defines a safe and efficient rapid filling procedure at the hydrogen station is considered an important issue. .
従来、ＦＣＶ向けの燃料ガス供給用の水素ステーションは、燃料ガス充填の際、車両情報をその場で伝えて、その情報に合致した燃料ガス充填制御をしていた。
しかしながら、燃料ガスを安全にＦＣＶの燃料タンクへより多く満充填する方法として、車両の燃料タンクの温度や圧力などの情報を逐次確認しながら、充填状況に応じて燃料ガス充填を行うことが知られている。
Conventionally, a hydrogen station for supplying fuel gas for FCV has transmitted vehicle information on the spot at the time of fuel gas filling, and performs fuel gas filling control that matches the information.
However, as a method of safely filling the fuel gas in the FCV fuel tank more safely, it is known to fill the fuel gas according to the filling situation while sequentially checking information such as the temperature and pressure of the fuel tank of the vehicle. It has been.
情報の逐次確認を実施するためには、車両情報を得るための通信信号の授受が必要とさるが、有線によるハード接点方式は接触の際に火花などが発生して危険であり、他方、無線方式では電波が長距離まで伝搬するため、妨害される帯域の電波の場合には通信障害となる危険が予測される。
このため、妨害される電波などの影響がないような近距離の無線通信が有効であり、そのような態様として、水素ステーションの燃料ガス供給口である充填ノズル周辺に設けた赤外線信号を受信する通信受光部と、車両側の燃料ガス供給口周辺に設けられた赤外線信号を送信する送信部とによって通信を行うものが好適に広まっている（例えば、特許文献１参照）。
In order to carry out the sequential confirmation of information, it is necessary to send and receive communication signals to obtain vehicle information. However, the hard contact method by wire is dangerous due to the occurrence of sparks at the time of contact. In the system, radio waves propagate to a long distance, and therefore, there is a risk of communication failure in the case of radio waves in a disturbed band.
For this reason, short-range wireless communication that is not affected by disturbed radio waves is effective, and as such an embodiment, an infrared signal provided around the filling nozzle that is the fuel gas supply port of the hydrogen station is received. What communicates by the communication light-receiving part and the transmission part which transmits the infrared signal provided around the fuel gas supply port by the side of a vehicle is spreading widely (for example, refer to patent documents 1).
燃料ガス供給装置において、充填ノズルに設けた通信受光部で受信した通信信号を充填制御に用いるために、充填制御を行う制御部まで信号を伝送しなければならない。
この信号伝送は、有線ケーブルなどを用いて伝送経路を構築するが、ＦＣＶに燃料充填の際に通信が正常に行えないと、安全な燃料供給に支障をきたすので、あらかじめ伝送経路が正常であるかを、例えば日常点検等で確認する必要がある。
In the fuel gas supply device, in order to use the communication signal received by the communication light receiving unit provided in the filling nozzle for the filling control, the signal must be transmitted to the control unit that performs the filling control.
In this signal transmission, a transmission path is constructed using a wired cable or the like. However, if communication cannot be performed normally when the FCV is filled with fuel, it will interfere with safe fuel supply, so the transmission path is normal in advance. For example, it is necessary to confirm this by daily inspection.
しかしながら、現状、伝送経路を含めた通信の良否を確認するためには、実際のＦＣＶの充填口（レセプタクル）に設けられた送信部から信号を送信し、それを充填ノズルに設けた通信受光部で受信する手段しかない。
この場合、例えば車両側がエラー信号を出力した場合の動作を確認したいときには、車両側をエラー信号の出る異常状態にしなければならない。
通信信号の伝送経路を含めた通信の良否の試験のために高価なＦＣＶを各水素ステーションで用意するのは、コスト面でも効率が悪く、さらに異常状態の信号を得るために、異常な状態を再現するのは安全上においても回避したい。
このように、水素ステーションにおける現状では、燃料ガス供給装置側で受け取る信号の通信状態を確認するためには、実際のＦＣＶで実際の状態を再現する以外に手段がないため、伝送経路を含めた通信の良否の確認が簡易かつ円滑にできないことが課題であった。
However, at present, in order to check the quality of communication including the transmission path, a signal is transmitted from a transmission unit provided in an actual FCV filling port (receptacle), and a communication light receiving unit provided in the filling nozzle There is only means to receive.
In this case, for example, when it is desired to confirm the operation when the vehicle side outputs an error signal, the vehicle side must be in an abnormal state where an error signal is output.
Providing expensive FCVs at each hydrogen station for testing the quality of communication including the transmission path of communication signals is inefficient in terms of cost, and in order to obtain abnormal signals, I want to avoid it for safety reasons.
As described above, in the present situation at the hydrogen station, since there is no means other than reproducing the actual state with the actual FCV in order to confirm the communication state of the signal received on the fuel gas supply device side, the transmission path is included. The problem was that the quality of communication could not be confirmed easily and smoothly.
本発明は、かかる課題を解決するためになされたものであり、燃料ガス供給装置の伝送経路を含めた通信の良否の確認を簡易かつ円滑に確認するために用いる燃料ガス供給装置用模擬信号発信装置を提供することを目的としている。 The present invention has been made in order to solve the above-described problem, and transmits a simulation signal for a fuel gas supply device used for simply and smoothly confirming the quality of communication including the transmission path of the fuel gas supply device.

以下、各構成について、複数の態様を含めて詳細に説明する。
The simulation signal transmission device 1 that transmits a simulation signal for operation confirmation to the fuel gas supply device 3 as described above includes a simulation signal transmission unit 17 that transmits a simulation signal, and a simulation signal transmitted by the simulation signal transmission unit 17. Is transmitted as an infrared signal, and a control unit 21 that controls the entire apparatus including the apparatus start-up control (ON / OFF) by the power ON / OFF switch 23 is provided.
Hereinafter, each configuration will be described in detail including a plurality of aspects.
＜模擬信号発信部＞
模擬信号発信部１７で発信する模擬信号は、燃料電池自動車から送信される通信信号を模擬した信号であって、燃料ガス供給装置３の伝送経路を含めた通信の良否の確認するための信号である。
模擬信号の一つの態様として、エラー信号（Abort信号やHalt信号）など接点（ON/OFF）によって動作する目的の信号については、図２に示すように、ON/OFFの切替信号を発信するための外部から操作可能な模擬信号ON/OFFスイッチ２２を設けるようにすればよい。これにより車両の接点信号を模擬することが可能となる。
<Simulation signal transmitter>
The simulation signal transmitted by the simulation signal transmission unit 17 is a signal that simulates a communication signal transmitted from the fuel cell vehicle, and is a signal for confirming the quality of communication including the transmission path of the fuel gas supply device 3. is there.
As one mode of the simulation signal, an ON / OFF switching signal is transmitted as shown in FIG. 2 for a target signal that operates by a contact (ON / OFF) such as an error signal (Abort signal or Halt signal). What is necessary is just to provide the simulation signal ON / OFF switch 22 which can be operated from the outside. This makes it possible to simulate a vehicle contact signal.
また、ＦＣＶ車両の模擬信号の他の態様として、車両のタンク内のガス温度やガス圧力の値等の水素ガスの充填に用いる設定値情報を発信可能である。この場合、模擬信号発信部１７は、図３に示すように、タンク内のガス温度やガス圧力の値を入力できるアプリを有した情報処理端末、例えばタブレット端末２５又はノートＰＣ２６から設定値情報を無線又は有線で受信するための受信部２７と、受信部２７で受信した設定情報を記憶する記憶部２９と、記憶部２９に記憶された設定情報を模擬信号として読み出す読み出し部３１とを備えるようにすればよい。
これにより、模擬信号発信装置１を、設定値などの入力に必要な機能を持たせずに携帯性がすぐれたものとすることができる。
As another mode of the simulation signal of the FCV vehicle, set value information used for filling hydrogen gas such as a gas temperature and a gas pressure value in the tank of the vehicle can be transmitted. In this case, as shown in FIG. 3, the simulation signal transmission unit 17 receives setting value information from an information processing terminal having an application capable of inputting the gas temperature and gas pressure values in the tank, for example, the tablet terminal 25 or the notebook PC 26. A receiving unit 27 for receiving wirelessly or by wire, a storage unit 29 for storing the setting information received by the receiving unit 27, and a reading unit 31 for reading out the setting information stored in the storage unit 29 as a simulation signal. You can do it.
Thereby, it is possible to make the simulated signal transmission device 1 excellent in portability without having a function necessary for inputting a set value or the like.
模擬信号ON/OFFスイッチ２２の切替信号や設定情報を模擬信号として送信すると、充填ノズル１１の通信受光部１３で受信されて伝送ケーブル１５を介して信号処理機７に送信されて、表示装置５のパネル状に表示される。これによって、伝送経路に異常のないことが確認できる。 When the switching signal or setting information of the simulation signal ON / OFF switch 22 is transmitted as a simulation signal, it is received by the communication light receiving unit 13 of the filling nozzle 11 and transmitted to the signal processor 7 via the transmission cable 15, and the display device 5. It is displayed in the form of a panel. Thereby, it can be confirmed that there is no abnormality in the transmission path.
＜信号送信部＞
信号送信部１９は、模擬信号発信部１７で発信された赤外線信号を充填ノズル１１に設けられた通信受光部１３に向けて送信するものである。
赤外線通信において、通信エラーを防止して通信を円滑に行うには、図１に示すように、信号送信部１９と通信受光部１３との間に所定の距離を離すようにするのが望ましい。
そこで、図４に示すように、信号送信部１９の近傍に、充填ノズル１１の通信受光部１３との間に所定の距離を保つための距離規制機能を設けるのが望ましい。
<Signal transmitter>
The signal transmission unit 19 transmits the infrared signal transmitted from the simulation signal transmission unit 17 toward the communication light receiving unit 13 provided in the filling nozzle 11.
In infrared communication, in order to prevent communication errors and perform communication smoothly, it is desirable to keep a predetermined distance between the signal transmission unit 19 and the communication light receiving unit 13 as shown in FIG.
Therefore, as shown in FIG. 4, it is desirable to provide a distance regulating function in the vicinity of the signal transmission unit 19 to maintain a predetermined distance between the filling nozzle 11 and the communication light receiving unit 13.
距離規制機能の一つの態様としては、図４に示すように、信号送信部１９の近傍から突出して先端が充填ノズル１１に当接するよう突起部材３３でもよい。
また、距離規制機能の他の態様としては、図５に示すように、信号送信部１９の近傍から突出する筒状体３５であり、筒状体３５の内面が突出方向に向かって広がる円錐面３７に形成されているものでもよい。
As one aspect of the distance regulating function, as shown in FIG. 4, a protruding member 33 may be used so that the tip protrudes from the vicinity of the signal transmission unit 19 and the tip abuts against the filling nozzle 11.
Further, as another aspect of the distance regulating function, as shown in FIG. 5, a cylindrical body 35 protruding from the vicinity of the signal transmission unit 19, and a conical surface in which the inner surface of the cylindrical body 35 extends in the protruding direction. 37 may be formed.
筒状体３５を用いる場合には、充填ノズル１１の先端を、図５に示すように、筒状体３５の内部に挿入すればよい。充填ノズル１１の外径は、種々のものが存在する（メーカーによりいくつか規格がある）ことから、図５（ａ）に示した外径Ａよりも径が大きい外径Ｂの充填ノズル１１の場合には、図５（ｂ）に示すように、充填ノズル１１の先端が筒状体３５の内面に当接する位置が筒状体３５の開口近傍になり、通信距離が少し長くなるが、いずれの場合にも充填ノズル１１と信号送信部１９との間に所定の距離を保つことができる。 When the cylindrical body 35 is used, the tip of the filling nozzle 11 may be inserted into the cylindrical body 35 as shown in FIG. Since there are various outer diameters of the filling nozzle 11 (there are some standards depending on the manufacturer), the filling nozzle 11 having an outer diameter B larger than the outer diameter A shown in FIG. In this case, as shown in FIG. 5B, the position where the tip of the filling nozzle 11 contacts the inner surface of the cylindrical body 35 is in the vicinity of the opening of the cylindrical body 35, and the communication distance becomes slightly longer. In this case, a predetermined distance can be maintained between the filling nozzle 11 and the signal transmission unit 19.
なお、距離規制機能として、筒状体３５を設ける場合、図６に示すように、内面の形状を先端側に向かって拡径する湾曲面３９からなるザグリ形状にしても、図５に示したものと同様の効果を奏する。図６（ａ）は外径Ｃの充填ノズル１１を挿入した状態を示し、図６（ｂ）は外径Ｃよりも外径の小さい外径Ｄの充填ノズル１１を挿入した状態を示している。 In addition, when providing the cylindrical body 35 as a distance control function, as shown in FIG. 6, even if the shape of the inner surface is changed to a counterbore shape composed of a curved surface 39 whose diameter increases toward the distal end side, as shown in FIG. Has the same effect as the one. 6A shows a state in which the filling nozzle 11 having an outer diameter C is inserted, and FIG. 6B shows a state in which the filling nozzle 11 having an outer diameter D smaller than the outer diameter C is inserted. .
距離規制機能の他の態様として、図７に示すように、図５、図６と同様に全体形状が筒状の筒状体３５からなり、充填ノズル１１の先端が挿入されるところに段部４１を設け、段部４１と信号送信部１９との距離を所定の距離にしたものでもよい。
この場合、段部４１を設けた部位の径を大小違った筒状体３５を複数準備し、これらを充填ノズル１１に合わせて交換可能なアダプタとして構成すればよい。図７（ａ）は外径Ｃの充填ノズル１１を挿入した状態を示し、図７（ｂ）は外径Ｃよりも外径の小さい外径Ｄの充填ノズル１１を挿入した状態を示している。
本例の場合には、段部４１と信号送信部１９との距離は一定となるので、赤外線通信を確実に行うことができる。
As another mode of the distance regulating function, as shown in FIG. 7, the overall shape is a cylindrical body 35 as in FIGS. 5 and 6, and the step portion is inserted at the end of the filling nozzle 11 is inserted. 41 may be provided, and the distance between the step portion 41 and the signal transmission unit 19 may be a predetermined distance.
In this case, it is only necessary to prepare a plurality of cylindrical bodies 35 having different diameters at the site where the stepped portion 41 is provided, and configure them as adapters that can be exchanged according to the filling nozzle 11. 7A shows a state in which the filling nozzle 11 having an outer diameter C is inserted, and FIG. 7B shows a state in which the filling nozzle 11 having an outer diameter D smaller than the outer diameter C is inserted. .
In the case of this example, the distance between the step portion 41 and the signal transmission portion 19 is constant, so that infrared communication can be performed reliably.
信号送信部１９の数としては、単数でもよいが、充填ノズル１１の通信受光部１３との位置ずれによっては通信エラーになる可能性がある。そこで、図８に示すように、複数の信号送信部１９を周方向の均等な位置に配置するようにしてもよい。図８（ａ）および（ｂ）では３個の例を、図８（ｃ）では１２個の例をそれぞれ示している。
信号送信部１９を複数設けることで、充填ノズル１１の通信受光部１３との赤外線通信を、通信エラーを回避して確実かつ円滑に行うことができる。
The number of signal transmission units 19 may be singular, but a communication error may occur depending on the positional deviation of the filling nozzle 11 from the communication light receiving unit 13. Therefore, as shown in FIG. 8, a plurality of signal transmission units 19 may be arranged at equal positions in the circumferential direction. 8A and 8B show three examples, and FIG. 8C shows 12 examples.
By providing a plurality of signal transmission units 19, infrared communication with the communication light receiving unit 13 of the filling nozzle 11 can be reliably and smoothly performed while avoiding communication errors.
なお、複数のアダプタを準備したり、あるいは複数の信号送信部１９を設けるのは煩雑であることから、図９に示すように、筒状体３５の先端側に段部４１を設けると共に、段部４１の後方（信号送信部１９側）に向かって半球状に凹む半球凹部４３を設け、半球凹部４３の中央に縦方向に延びるスリット４５を設けるようにしてもよい。
半球凹部４３は、図１０に示すように、取り付け用のフランジ部４７と、スリット４５が形成された半球面体部品４９からなる。
Since it is troublesome to prepare a plurality of adapters or to provide a plurality of signal transmission units 19, as shown in FIG. 9, a stepped portion 41 is provided on the distal end side of the cylindrical body 35, and a stepped portion is provided. A hemispherical concave portion 43 that is recessed in a hemispherical shape toward the rear of the portion 41 (on the signal transmission unit 19 side) may be provided, and a slit 45 extending in the vertical direction may be provided in the center of the hemispherical concave portion 43.
As shown in FIG. 10, the hemispherical concave portion 43 includes a flange portion 47 for attachment and a hemispherical component 49 in which a slit 45 is formed.
図９に示した距離規制機能においては、充填ノズル１１は段部４１まで挿入され、スリット４５を介して発信される赤外線を受光する。段部４１の形成された部位よりも小径の充填ノズル１１は半球凹部４３に当接することになるが、この場合も信号送信部１９と充填ノズル１１の先端との間を所定の距離に保つことができる。 In the distance regulation function shown in FIG. 9, the filling nozzle 11 is inserted up to the step portion 41 and receives infrared rays transmitted through the slit 45. The filling nozzle 11 having a smaller diameter than the portion where the step portion 41 is formed comes into contact with the hemispherical concave portion 43, and in this case as well, a predetermined distance is maintained between the signal transmission unit 19 and the tip of the filling nozzle 11. Can do.
＜制御部＞
制御部２１は装置全体の制御を行うものであり、装置の電源ON/OFFスイッチ２３によって装置全体の起動と停止（電源遮断）を制御できる。
また、本装置の電源として、外部電源からケーブルによって供給するようにしてもよいが、図１１に示すように、装置内に電源としてバッテリー、電池を含む内部電源５１を有するようにしてもよい。この場合、制御部２１は電源の制御を行う。内部電源５１を用いることで、携帯性が向上し、利便性が高くなる。充填ホース９の自由度は限りがあるので、模擬信号発信装置１の携帯性が高まると、充填ノズル１１まで模擬信号発信装置１を持っていくことができ、作業性が大幅に向上する。
<Control unit>
The control unit 21 controls the entire apparatus, and can control the start and stop (power cutoff) of the entire apparatus by the power ON / OFF switch 23 of the apparatus.
In addition, as a power source of the present apparatus, it may be supplied from an external power source through a cable, but as shown in FIG. 11, an internal power source 51 including a battery and a battery may be included in the apparatus. In this case, the control unit 21 controls the power supply. By using the internal power supply 51, portability is improved and convenience is enhanced. Since the degree of freedom of the filling hose 9 is limited, if the portability of the simulation signal transmission device 1 is increased, the simulation signal transmission device 1 can be brought to the filling nozzle 11 and workability is greatly improved.
なお、模擬信号発信装置１は、水素ステーションなどの可燃性ガスを利用する環境下で用いるため、防爆構造であることで安全性が高まる。一方でコストや携帯性を考えた場合、防爆構造によらずとも運用の仕方で安全性を確保することが可能であれば、これに越したことはない。 In addition, since the simulation signal transmission device 1 is used in an environment using a combustible gas such as a hydrogen station, the safety is enhanced by the explosion-proof structure. On the other hand, when cost and portability are considered, if safety can be ensured by an operation method without using an explosion-proof structure, this is not exceeded.
このための方法として、燃料ガスが漏れていた場合には、模擬信号発信装置１内部に電気が流れない状態にすればよく、具体的には、制御部２１に連動する電源ON/OFFスイッチ２３を電源ONにできないか、あるいは電源ON状態の場合には電源OFF、すなわち停止（電源遮断）するようにすればよい。そのためには、模擬信号発信装置１が、燃料ガスを爆発下限濃度で検知できるガス検知器５３を備えるようにすればよい。
これによって、ガス検知器５３が爆発下限界に達しないよう監視している環境で、模擬信号発信装置１を起動させること、および動作を継続させることができる。これによって、仮に模擬信号発信装置１の内部の接点部分で電気火花が発生しても、爆発が発生しない環境を保持することができる。
もっとも、ガス検知器５３は模擬信号発信装置１が内蔵する必要はなく、図１２に示すような一般的なガス検知器５３を、保持できるような保持部５５を模擬信号発信装置１が備えればよい。図１３は、模擬信号発信装置１がガス検知器５３の一部を挿入状態で保持する保持部５５を備えた場合の外形の一例を示すものである。
As a method for this, when the fuel gas is leaked, it is only necessary to prevent electricity from flowing into the simulation signal transmission device 1. Specifically, the power ON / OFF switch 23 interlocked with the control unit 21. If the power cannot be turned on, or if the power is on, the power may be turned off, that is, stopped (power cut off). For this purpose, the simulation signal transmission device 1 may be provided with a gas detector 53 that can detect the fuel gas at the lower explosion limit concentration.
As a result, the simulated signal transmission device 1 can be activated and the operation can be continued in an environment in which the gas detector 53 is monitoring so as not to reach the lower explosion limit. As a result, even if an electric spark occurs at the contact portion inside the simulated signal transmission device 1, an environment in which no explosion occurs can be maintained.
However, it is not necessary for the gas detector 53 to be built in the simulation signal transmission device 1, and the simulation signal transmission device 1 includes a holding portion 55 that can hold a general gas detector 53 as shown in FIG. 12. That's fine. FIG. 13 shows an example of the external shape when the simulated signal transmission device 1 includes a holding portion 55 that holds a part of the gas detector 53 in an inserted state.
なお、上述した爆発の危険を回避ため、模擬信号発信装置１の電源をONするには、ガス検知器５３が動作している状態を必要条件とすることで、常にガス検知器５３の監視下にあって、模擬信号発信装置１を動作させることができる。
このためには、図１４に示すように、ガス検知器５３の停止状態およびガス漏洩検知状態を認識できる接点によってガス検知器５３が制御部２１に接続され、制御部２１はガス検知器５３が停止状態においては電源をONしないように制御するようにすればよい。
これによって、仮に模擬信号発信装置１の内部の接点部分で電気火花が発生しても、爆発が起きない環境を保持することができる。
In order to avoid the above-described explosion risk, the simulation signal transmission device 1 can be turned on under the condition that the gas detector 53 is in operation, so that the gas detector 53 is always monitored. Therefore, the simulated signal transmission device 1 can be operated.
For this purpose, as shown in FIG. 14, the gas detector 53 is connected to the control unit 21 through a contact that can recognize the stop state and the gas leak detection state of the gas detector 53. Control should be made so that the power is not turned on in the stop state.
As a result, even if an electric spark occurs at the contact portion inside the simulated signal transmission device 1, it is possible to maintain an environment in which no explosion occurs.
さらに、模擬信号発信装置１が起動中において、ガス検知器５３がガス漏洩を検知した場合は、制御部２１が模擬発信装置１を停止（電源遮断）させることができる。 Furthermore, when the simulated signal transmission device 1 is activated, if the gas detector 53 detects a gas leak, the control unit 21 can stop the simulated transmission device 1 (power is cut off).
また、図１５に示すように、模擬信号発信装置１は、予め微弱電流で一部が動作することができるスタンバイ状態として機能することができ、制御部２１はガス検知器５３と無線で通信できる通信部５７を有し、制御部２１はガス検知器５３が動作していることが通信により検知できたら、模擬信号発信装置１の電源ON/OFFスイッチ２３をONにすることで、スタンバイ状態から起動するようにしてもよい。これによって、仮に模擬信号発信装置１の接点部分で動作電流により電気火花が発生しても、爆発が発生しない環境を保持することができる。 Further, as shown in FIG. 15, the simulated signal transmission device 1 can function as a standby state in which a part can be operated with a weak current in advance, and the control unit 21 can communicate with the gas detector 53 wirelessly. If the control unit 21 detects that the gas detector 53 is operating by communication, the control unit 21 turns on the power ON / OFF switch 23 of the simulation signal transmission device 1 to turn it on from the standby state. You may make it start. As a result, even if an electric spark is generated by an operating current at the contact portion of the simulated signal transmission device 1, an environment in which no explosion occurs can be maintained.
さらに、図１６に示すように、制御部２１が、ガス検知器５３のエラー信号などを無線により受信する通信部５７を有し、ガス検知器５３がたとえば水素ガスを検知して、その濃度が爆発下限界に近づいてエラー信号を発信し、模擬信号発信装置１がこれを受信すると、制御部２１は模擬信号発信装置１の動作をスタンバイ状態にするか、または停止（電源遮断）するようにしてもよい。
これによって、仮に水素ガスが漏洩したとしても、模擬信号発信装置１の電気エネルギーで爆発が発生しないように、安全に停止させることができる。
Furthermore, as shown in FIG. 16, the control unit 21 has a communication unit 57 that wirelessly receives an error signal of the gas detector 53, and the gas detector 53 detects, for example, hydrogen gas, and the concentration thereof is When the explosive limit is approached and an error signal is transmitted and the simulated signal transmitting device 1 receives the error signal, the control unit 21 sets the operation of the simulated signal transmitting device 1 in a standby state or stops (power is cut off). May be.
Thereby, even if hydrogen gas leaks, it can be safely stopped so that no explosion occurs due to the electric energy of the simulated signal transmission device 1.
