Abstract


The ship cabin monitoring alarm system is an important part of the automation of the ship, and its main function is to detect and control the working status and parameters of the mechanical and electrical equipment, and instructions, alarm, control and recording. The reliability of the system working directly affect the safe navigation of the ship. The initial cabin automated alarm system is mainly composed of relay and semiconductor logic circuit, now is not suitable for the engine room automation development requirements and provisions of international maritime organizations and classification societies. In order to adapt to the requirements of modern automation cabin, PLC control gradually replace the relay contactor control the main part of the ship engine room control, the control system more secure, fast and reliable. Ship in normal navigation process, host, generators and cabin other hosts, work status and parameters of the auxiliary services are constantly changing, in order to keep abreast of the operation of equipment, in the central control room extensive knowledge of the various operating conditions of the equipment, so you need a set of real-time, reliable work of the cabin to monitor the alarm system. When the operating parameters of the device exceeds a certain preset limits, can emit sound and light alarm to remind the engineer on duty, can improve the fault prevention capacity and shorten the time of the investigation and treatment failure. This shows the importance of ship cabin real-time monitoring of alarm systems. This article is based on the Dalian Maritime University training vessel \communication module, a control module, a display module. PLC as the control core system design using fieldbus technology acquisition parameters of the various monitoring points within the cabin through the data acquisition module up into the control module for processing through the communication module (field bus), and the display module on the visual display. This paper introduces the basic operating principle of the data acquisition system, a brief introduction to the course of development of the PLC and its advantages as well as the system of PROFIBUS, focuses on the structure of the PROFIBUS protocol. Cabin alarm system monitoring back-end database, and Windows platforms RSViewSupervisory Edition completed the design of a the ship cabin monitoring alarm system software development tools. The software's true reproduction of the real ship monitoring alarm system, simulate its workflow, with a friendly and interactive interface.
