Since the 1960s,the leading shipbuilding countries begin to study on the ship condition monitoring and trouble analysis, Nobodys engine-room shipping on duty appeared .certainly the condition monitoring and trouble analysts system also meets some question ,such as: only give alarm or show the actual value of the parameter, does not possess the function of analyzing and giving operator the direct suggestion function about the complicated trouble reason , Only monitor the present running conditions, does not possess the function of predicting equipment future and run reliability though trouble analysis technology makes good progress in these yeas, onboard the ship is still rare .aiming to improve the shipping safety, this paper make some research work on the ship engine-room, the main innovation are as follows:Firstly, this paper introduces and analyzes the research work and current situation on the condition monitoring, trouble analysis and safety assessment .especially in the maritime fields .

船舶机舱系统结构复杂，故障源多，征兆参数丰富，故障与征兆之间常常不存在简单的对应关系，而是相互影响，关系错综复杂。60年代以来，世界上先进的造船国家都相继开展了船舶机械状态监控和故障诊断的研究，出现了无人值班机舱船舶，但仍存在不足之处，如：只给报警提示或显示参数的实际值，不具备对复杂故障的原因分析并给操作者以直接的提示或建议功能；只监测当前的运行状况，不具备预测设备未来运行可靠性的功能；尽管近年来设备故障诊断技术得到了很大的发展，但真正能成功应用于实船的尚不多见。本论文以船舶机舱为对象，以提高船舶营运安全性为目标，来研究船舶机舱的安全控制技术，主要内容如下：首先，介绍和分析了状态监测、故障诊断和安全评估的研究内容和现状，尤其是在船舶领域的研究近况。

The invention relates to a code device, which is characterized in that: the device safety storage section has a blank mark which comprises at least two conditions as effective and ineffective; when the blank mark is effective, the code device only can be logged in by the device initial user; and when it is ineffective, the code device can be logged in by other user without the initial user.
