The Study On Novel Monitor System Of Marine Engine Room Lab

In conjunction with the reform in the automated engine room laboratory monitoring system of Qingdao Ocean Shipping Mariners College in which the writer participated, this paper describes the monitoring system in detail, including the working principle of the data sampling system, CAT computer monitoring system, the components and function of the newly-established monitoring system, the design principle of the network control level and management level as well as the self-detecting and trouble-shooting of the system.Based on the original one, a new system has been set up during this reform which is as advanced as the engine room monitor and alarm system in the late 90's. The new system has many advantages, such as friendly interface, convenient in operation, reliable and catering to the need of training. During the development of the new system, a lot of advanced techniques were adopted covering network, database, object-oriented programming, internet, PLC and DDE etc.. Therefore the new system possesses the following major technological advantages:1 .The system has a typical module structure. The monitoring system is no longer an ancillary to the equipment and is independent of the controlled unit.2.The monitoring function is affected mainly by means of software so that it can be increased or altered conveniently.3.Hardwares and softwares are adaptable and interchangeable. The upgraded is compatible with the old one.4.Redundancy control can be readily provided and reliability is increased.5.It facilitates the establishment of the management center for controlling the whole ship.
