Description

この発明は、火災報知システムに関するものである。 The present invention relates to a fire alarm system.

火災報知システムが国際公開２００５−０２２４７８号公報（特許文献１）に記載されている。同公報のシステムでは、形状記憶合金体が対の可溶絶縁電線のまわりに巻き付けられ、形状記憶合金体および可溶絶縁電線によって火災センサが構成される。そして、電線の導体がブザー電源に接続される。 A fire alarm system is described in International Publication No. 2005-022478 (Patent Document 1). In the system of the publication, a shape memory alloy body is wound around a pair of soluble insulated wires, and a fire sensor is constituted by the shape memory alloy body and the soluble insulated wires. And the conductor of an electric wire is connected to a buzzer power supply.

一方、特に、多数の産業機械のある工場の場合、誤動作、故障などの原因で産業機械の内部機器が異常発熱し、火災が発生することは少なくない。 On the other hand, in particular, in a factory with a large number of industrial machines, it is not uncommon for internal equipment of industrial machines to overheat due to malfunctions or failures, resulting in a fire.

この発明は、工場の産業機械の内部機器、遊戯施設の遊戯機器または自動販売機の異常発熱および火災に的確に対処することを目的としてなされたものである。
国際公開２００５−０２２４７８号公報 The present invention has been made for the purpose of accurately dealing with abnormal heat generation and fires in internal equipment of industrial machinery in factories, amusement equipment in amusement facilities or vending machines.
International Publication No. 2005-022478

この発明によれば、形状記憶合金体が対の可溶絶縁電線のまわりに巻き付けられ、形状記憶合金体および絶縁電線によって火災センサが構成される。さらに、火災センサが工場の産業機械の内部機器、遊戯施設の遊戯機器または自動販売機器に設けられ、電線の導体がブザーおよび電源に接続される。 According to this invention, a shape memory alloy body is wound around a pair of soluble insulated wires, and a fire sensor is constituted by the shape memory alloy body and the insulated wires. Furthermore, a fire sensor is provided in an internal device of an industrial machine in a factory, an amusement device or a vending machine in an amusement facility, and a conductor of an electric wire is connected to a buzzer and a power source.

以下、この発明の実施例を説明する。 Examples of the present invention will be described below.

図１はこの発明にかかる火災報知システムを示す。このシステムでは、上記公報のシステムと同様、形状記憶合金体が対の可溶絶縁電線Ｄ１，Ｄ２のまわりに巻き付けられ、形状記憶合金体および絶縁電線Ｄ１，Ｄ２によって火災センサＡ，Ｂ，Ｃが構成される。さらに、多数の産業機械１のある工場において、火災センサＢが各産業機械１の内部機器２に設けられている。たとえば、内部機器２は複数の端子台３を有し、火災センサＢは端子台３付近に設けられている。さらに、火災センサＡが各産業機械１内に設けられ、警報器Ｅが各産業機械１の外壁に設けられ、警報器Ｅにブザーおよび電池が内蔵され、火災センサＣが警報器Ｅ自体に設けられており、電線Ｄ１，Ｄ２がブザーおよび電池に接続されている。 FIG. 1 shows a fire alarm system according to the present invention. In this system, the shape memory alloy body is wound around the pair of soluble insulated wires D1 and D2 as in the system of the above publication, and the fire sensors A, B, and C are moved by the shape memory alloy body and the insulated wires D1 and D2. Composed. Furthermore, in a factory with a large number of industrial machines 1, a fire sensor B is provided in the internal device 2 of each industrial machine 1. For example, the internal device 2 has a plurality of terminal blocks 3, and the fire sensor B is provided in the vicinity of the terminal block 3. Furthermore, a fire sensor A is provided in each industrial machine 1, an alarm device E is provided on the outer wall of each industrial machine 1, a buzzer and a battery are built in the alarm device E, and a fire sensor C is provided in the alarm device E itself. The electric wires D1 and D2 are connected to the buzzer and the battery.

したがって、産業機械の内部機器２が異常発熱し、火災が発生したとき、その熱によって火災センサＡ，Ｂ，Ｃが動作し、電流が電池から供給され、ブザーに流れ、電流によってブザーが鳴る。したがって、異常発熱および火災に的確に対処することができる。 Therefore, when the internal device 2 of the industrial machine abnormally generates heat and a fire occurs, the fire sensors A, B, and C are operated by the heat, current is supplied from the battery, flows to the buzzer, and the buzzer sounds. Therefore, it is possible to appropriately cope with abnormal heat generation and fire.

この実施例では、ピンが警報器Ｅに差し込まれており、非常事態のとき、ピンを警報器Ｅから抜き取ると、スイッチによってブザーが鳴り、非常事態に的確に対処することもできる。警報器Ｅは携帯型のもので、取り外し可能である。 In this embodiment, the pin is inserted into the alarm device E. In the event of an emergency, if the pin is removed from the alarm device E, a buzzer will sound by the switch and the emergency situation can be dealt with properly. The alarm device E is portable and can be removed.

火災センサＡ，Ｂを電池ではなく、それ以外の電源に接続してもよい。火災センサを遊戯施設の遊戯機器または自動販売機器に設けると、遊戯機器または自動販売機器が異常発熱し、火災が発生したとき、それに的確に対処することができる。 The fire sensors A and B may be connected to a power source other than the battery. When a fire sensor is provided in a game machine or vending machine in a play facility, when the game machine or vending machine abnormally generates heat and a fire breaks out, it can be dealt with appropriately.
