AUSE-V1 捜索救助フライトシミュレータ

1、目的と意義

---

石油は現代社会において非常に重要な資源であり、石油化学プラントや石油・ガスパイプラインの大型設備の安定性は非常に重要です。化学プラントの設備や設備は巨大で複雑で、高温高圧の条件下で稼働しています。長時間空気にさらされ、雨や風にさらされるため、経年劣化や腐食などの問題により重大な漏水事故が発生しやすくなります。化学プラントの正常な運用を確保するためには、化学プラントとパイプライン設備の定期検査を実施して、機器とパイプラインの隠れた危険を時間内に排除する必要があります。UAVパトロール検査は、ドローンを使用して他の補助機器を運び、化学プラントを検査する新しい検査技術です。手作業による巡回検査では困難な、または手作業による検査では到達しにくい巡回検査エリアを効果的に補完できます。これにより、検査効率が大幅に向上し、設置機器の正常な動作が保証されます。
