【摘要】：隨著世界貿(mào)易的繁榮,世界海運量也持續(xù)增長。同時隨之出現(xiàn)了不可避免的環(huán)境污染問題,特別是船舶含油污水排放問題。國際海事組織為此出臺了多種法律、法規(guī)來規(guī)范含油污水的排放。但是由于相關的監(jiān)管措施、條件以及監(jiān)控設備不夠完善,仍然存在船舶將含油污水肆意地排入大海的情況。船舶排油監(jiān)控系統(tǒng)是監(jiān)控含油壓載水或其他油污水從貨艙區(qū)域排入海中的系統(tǒng)。監(jiān)控系統(tǒng)主要由取樣系統(tǒng)、油分計、測控單元、流量計、主控單元等組成。當含油壓載水或其他油污水從貨艙區(qū)域排入海中時,監(jiān)控系統(tǒng)開始取樣、分析、記錄。當排放條件達不到規(guī)定要求時,則終止排放物排入海中,防止海洋污染。 本課題首先通過對油船排油監(jiān)控系統(tǒng)的功能、結構和設備進行深入分析,結合相關公約規(guī)范和技術條件的要求對排油監(jiān)控系統(tǒng)進行總體的設計。然后進行系統(tǒng)主控單元的設計和實現(xiàn),主控單元核心處理器選擇ARM Cortex-M3內(nèi)核的STM32處理器。硬件方面采用Altium Designer10軟件進行主控單元的原理圖和PCB圖設計。選擇和理的外圍器件,創(chuàng)建元件庫,按照邏輯功能連接好元器件,包括開關量輸入輸出電路、模擬量輸入輸出電路、以太網(wǎng)、RS485、CAN接口電路等。軟件方面采用Keil MDK軟件開發(fā)環(huán)境對所制作的電路板編程,使其能夠準確的實現(xiàn)排油監(jiān)控系統(tǒng)主控制單元所具備的功能,包括處理航速、油份濃度、流量等模擬信號輸入,各控制閥門和電機的開關量輸入輸出,液晶顯示,打印記錄以及相關的邏輯與計算功能等。最后再通過上位機對該系統(tǒng)進行模擬調(diào)試,并不斷的優(yōu)化系統(tǒng)。
[Abstract]:With the prosperity of world trade, the volume of sea transportation in the world continues to increase. At the same time, there are inevitable environmental pollution problems, especially the discharge of oily sewage from ships. The International Maritime Organization (IMO) has issued a variety of laws for this purpose. Regulations to regulate the discharge of oily sewage. But due to the relevant regulatory measures, conditions and monitoring equipment is not perfect. There is still the situation that ships discharge oily sewage into the sea wantonly. The ship oil discharge monitoring system is a system for monitoring the discharge of oily ballast water or other oily water into the sea from the cargo tank area. The monitoring system is mainly composed of sampling system. Oil content meter, measurement and control unit, Flowmeter, main control unit, etc. When oil ballast water or other oily water is discharged into the sea from the cargo tank area, the monitoring system begins to sample and analyze. Record. When discharge conditions do not meet specified requirements, the discharge is terminated to prevent marine pollution. Firstly, the function, structure and equipment of the oil discharge monitoring system of oil tanker are deeply analyzed. Combined with the requirements of the relevant conventions and technical conditions, the overall design of the oil discharge monitoring system is carried out. Then, the design and implementation of the main control unit of the system are carried out. The main control unit core processor selects the STM32 processor of the ARM Cortex-M3 kernel. Altium is used in the hardware. The Designer10 software is used to design the schematic diagram and PCB diagram of the main control unit. The component library is created and the components are connected according to the logic function, including the switch input and output circuit, the analog input and output circuit, and the Ethernet RS485. CAN interface circuit and so on. The software uses the Keil MDK software development environment to program the circuit board, so that it can accurately realize the function of the main control unit of the oil discharge monitoring system. Including processing speed, oil concentration, flow rate and other analog signal input, each control valve and motor switch input and output, LCD display. Finally, the system is simulated and debugged by the upper computer, and the system is optimized continuously.
