Abstract: The wired monitoring mode is commonly used in the traditional ship compastment fire monitoring systems, whose disadvantages are high cost, complex wiring, poor scalability and hard to maintain. The disign scheme of the ship fire safety monitoring system based on ZigBee technology can achieve the fire monitoring inside the ship compartments under the precondition of low cost and easy implementation. If the ZigBee based wireless network with low-power comsumption, high reliability and scalability is applied in fire monitoring, a variety of on-site wiring can be avoided, the system′s flexibility and reliability enhanced, and the of ability ship fire monitoring improved.

我國是一個海洋大國,海洋面積為陸地面積的三分之一,各類船艇在國防、國民經(jīng)濟和海洋開發(fā)等方面都占有十分重要的地位。船艇的基本部分為船體,其內(nèi)部有工作艙、生活艙、貯藏艙、儀器設備艙等各種用途的艙室[1]。由于船艇艙室多為狹小的半封閉式空間,艙內(nèi)消防安全監(jiān)測尤為重要。
傳統(tǒng)的船艇艙室消防安全監(jiān)測系統(tǒng)一般采用有線監(jiān)控的方式,火災探測器直接通過硬線與控制器連接。有線監(jiān)測系統(tǒng)造價高、布線復雜、擴展性差、設備后期維修困難[2]。目前,無線傳感器網(wǎng)絡已經(jīng)在各種環(huán)境條件的監(jiān)控系統(tǒng)中得到了廣泛的應用,船艇艙室的監(jiān)測系統(tǒng)使用無線傳感器網(wǎng)絡,不會出現(xiàn)傳統(tǒng)布線方法帶來的種種不便。由于消防安全為長期的連續(xù)監(jiān)測,使用ZigBee這種安裝簡單、能量消耗小的短距離無線通信技術(shù)十分適合。本文提出了一種基于ZigBee技術(shù)的船艇消防安全監(jiān)測系統(tǒng)的設計方案,在成本低、易于實現(xiàn)的前提下實現(xiàn)對船艇各個艙室內(nèi)部的消防安全監(jiān)測。
