【摘要】：为保证船舶在海上安全航行并顺利完成其使命任务，在确保船舶燃油、淡水、润滑油等液舱的装载液位、液温、液量满足航行要求的同时，还需确保船舶具有良好的稳性和浮态。因此，本文结合某综试舰研发了一套船舶液舱装载状态及稳性的自动监测系统。该系统的研发大大提高了船舶的安全性、可靠性，减少了人力资源的消耗、提高了工作效率，通过对船舶液舱的监测还有效的避免了液舱调驳或补给过程中液体外溢，给海洋环境造成污染的可能性。本文以某综试舰为设计目标对船舶自动监测系统进行设计，，在各类液舱内分别布置相应数目和型号的液温、液位监测传感器。将传感器采集的信号传输给PLC，并通过PLC对信号进行处理转换后传输给安装在上位机中的系统软件。系统软件主要用于显示现场采集的监测数据，同时实时计算液舱各类参数和船舶的浮态稳性数据并进行报警，实现对数据的归档、查询、打印等功能。系统研发涉及到的具体工作内容如下：（1）对船舶自动监测报警系统进行相关研究，以某综试舰为原型确定所需监测对象，采用的平台软件以及PLC、传感器、计算机、通讯卡等硬件设备。（2）结合所需监测对象，采用WinCC组态软件对系统进行设计，实现对监测对象的实时监测、报警、数据归档、数据查询、报表打印等功能。该系统共设置7个主界面，54个监测点。（3）采用综合试验舰浮态辅助决策系统对液舱参数和船舶稳性数据进行计算。通过数据交换技术并对综合试验舰浮态辅助决策系统的部分程序进行改写，一方面实现了该系统对液舱参数及稳性数据的自动计算功能，另一方面实现了以该系统作为船舶液舱装载状态及稳性自动监测系统的主系统。（4）通过数据交换技术，将综合试验舰浮态辅助决策系统中计算得出的稳性数据实时传递给WinCC软件设计的监测系统，最终实现以WinCC设计系统为船舶液舱装载状态及稳性自动监测系统的主系统。（5）最后根据监测系统的设计要求以及监测对象的位置合理布置传感器和PLC这些硬件设备，并进行现场布线实现装有系统软件的计算机与现场硬件设备之间的物理连接。对组态软件与PLC硬件之间的通讯进行研究，合理设置PLC与组态软件之间的逻辑连接，实现系统软件与现场设备的通讯。该研发系统在实船上使用效果良好。
[Abstract]:In order to ensure the safe navigation of the ship at sea and the smooth completion of its mission, while ensuring that the oil, fresh water and lubricating oil tanks of the ship meet the requirements of navigation, It is also necessary to ensure good stability and buoyancy of the ship. Therefore, an automatic monitoring system for the loading state and stability of the ship tank is developed in this paper. The research and development of the system has greatly improved the safety and reliability of the ship, reduced the consumption of human resources, improved the working efficiency, and effectively avoided the overflow of liquid in the course of tank refuelling or replenishment by monitoring the tank of the ship. The possibility of causing pollution to the marine environment. In this paper, an automatic ship monitoring system is designed for a fully mechanized ship. The corresponding number and type of liquid temperature and liquid level monitoring sensors are arranged in various tanks. The signal collected by the sensor is transmitted to the PLC, and the signal is processed and converted by PLC to the system software installed in the upper computer. The system software is mainly used to display the monitoring data collected on the spot, at the same time to calculate the parameters of tank and the floating stability data of the ship in real time and to alarm, realize the functions of archiving, querying, printing and so on. The specific work involved in the system development is as follows: In this paper, a ship automatic monitoring and alarm system is studied. The monitoring object, platform software, PLC, sensor, computer, communication card and other hardware equipments are determined based on the prototype of a fully mechanized ship. The system is designed with WinCC configuration software, which can realize the functions of real-time monitoring, alarm, data archiving, data query, report printing and so on. The system has 7 main interfaces and 54 monitoring points. The parameters of the tank and the stability data of the ship are calculated by the comprehensive test ship floating auxiliary decision system. By means of data exchange technology and rewriting some programs of the auxiliary decision system for floating state of synthetic test ship, on the one hand, the automatic calculation function of the system for tank parameters and stability data is realized. On the other hand, the system is used as the main system of the automatic monitoring system for the loading state and stability of the ship's tank. Through data exchange technology, the stability data obtained from the comprehensive test ship floating auxiliary decision system is transferred to the monitoring system designed by WinCC software in real time. Finally, the WinCC design system is used as the main system of the automatic monitoring system for the loading state and stability of the ship's tank. Finally, according to the design requirements of the monitoring system and the location of the monitoring object, the sensors and PLC hardware equipments are arranged reasonably, and the physical connection between the computer equipped with the system software and the field hardware equipment is realized. The communication between configuration software and PLC hardware is studied, the logical connection between PLC and configuration software is reasonably set up, and the communication between system software and field equipment is realized. The research and development system has a good effect on the real ship.
