【摘要】：隨著航運(yùn)業(yè)的快速發(fā)展，，船舶的安全問(wèn)題越來(lái)越受到人們的關(guān)注。船舶動(dòng)力裝置是產(chǎn)生、傳遞和消耗能量的全部機(jī)械設(shè)備的總和，為船舶的正常航行和其它各項(xiàng)工作開(kāi)展提供足夠的能量，它是船舶上最重要的組成部分。各類船舶故障中約有60%-80%的故障是由動(dòng)力裝置設(shè)備部分引起的，傳統(tǒng)故障診斷方法較落后、效率低、勞動(dòng)強(qiáng)度大、維護(hù)成本高，因此需要開(kāi)展船舶動(dòng)力裝置設(shè)備的狀態(tài)監(jiān)測(cè)與故障診斷技術(shù)研究。將現(xiàn)代計(jì)算機(jī)技術(shù)和嵌入式技術(shù)應(yīng)用于船舶監(jiān)測(cè)與故障診斷技術(shù)研究，提出了一種基于計(jì)算機(jī)PCI接口的船舶動(dòng)力裝置監(jiān)測(cè)和故障診斷系統(tǒng)設(shè)計(jì)方案。本文主要講述了系統(tǒng)的平臺(tái)設(shè)計(jì)方法和過(guò)程，包括以下內(nèi)容： 介紹了船舶動(dòng)力裝置和故障診斷技術(shù)的相關(guān)知識(shí)，結(jié)合當(dāng)前國(guó)內(nèi)外在該領(lǐng)域的研究現(xiàn)狀，分析了船舶動(dòng)力裝置監(jiān)測(cè)與故障診斷系統(tǒng)平臺(tái)的功能需求，設(shè)計(jì)了整個(gè)系統(tǒng)的總體方案，并對(duì)各個(gè)單元模塊的設(shè)計(jì)方案進(jìn)行論證。 系統(tǒng)以工控機(jī)和cyclone III系列FPGA控制器為核心搭建硬件平臺(tái)，包括基于PCI9054的PCI接口電路，EEPROM電路，F(xiàn)PGA控制電路，485通信接口電路，基于SJA1000的CAN總線接口電路和基于DM9000A的以太網(wǎng)接口電路。選取合適的傳感器設(shè)計(jì)檢測(cè)電路測(cè)量船舶動(dòng)力裝置設(shè)備的溫度、壓力、轉(zhuǎn)速等重要熱力參數(shù)，并設(shè)計(jì)合適的信號(hào)采集電路采集這些數(shù)據(jù)，以實(shí)現(xiàn)對(duì)船舶動(dòng)力裝置設(shè)備運(yùn)行狀態(tài)的實(shí)時(shí)監(jiān)測(cè)。 FPGA控制器上開(kāi)發(fā)基于Nios II軟核處理器的SOPC系統(tǒng)，用來(lái)控制整個(gè)下位機(jī)硬件平臺(tái)的運(yùn)行。在Quartus II開(kāi)發(fā)環(huán)境下編輯FPGA子程序，采用VerilogHDL語(yǔ)言開(kāi)發(fā)自定義IP模塊實(shí)現(xiàn)與各外設(shè)模塊之間的實(shí)時(shí)通信。 采用Windows環(huán)境下的WDM模型驅(qū)動(dòng)設(shè)計(jì)了PCI9054驅(qū)動(dòng)程序，實(shí)現(xiàn)設(shè)備的即插即用，并在VS2008開(kāi)發(fā)環(huán)境開(kāi)發(fā)系統(tǒng)的監(jiān)測(cè)與故障診斷應(yīng)用軟件。最后，本文提出了船舶動(dòng)力裝置設(shè)備的神經(jīng)網(wǎng)絡(luò)故障診斷專家系統(tǒng)設(shè)計(jì)思路。
[Abstract]:With the rapid development of shipping industry, people pay more and more attention to the safety of ships. Providing sufficient energy for the normal navigation and other work of the ship, which is the most important part of the ship. About 60% to 80% of all kinds of ship faults are caused by power plant equipment, The traditional fault diagnosis method is backward, low efficiency, high labor intensity, high maintenance cost, Therefore, it is necessary to carry out the research on condition monitoring and fault diagnosis of marine power plant equipment, and apply modern computer technology and embedded technology to ship monitoring and fault diagnosis technology. This paper presents a design scheme of marine power plant monitoring and fault diagnosis system based on computer PCI interface. This paper mainly describes the platform design method and process of the system, including the following contents:. This paper introduces the relevant knowledge of ship power plant and fault diagnosis technology, and analyzes the functional requirements of the platform of ship power plant monitoring and fault diagnosis system, combined with the current research situation in this field at home and abroad. The overall scheme of the whole system is designed, and the design scheme of each unit module is demonstrated. The hardware platform of the system is based on the industrial control computer and cyclone III series FPGA controller, including the PCI interface circuit based on PCI9054 and the EEPROM control circuit and the FPGA485 communication interface circuit. The CAN bus interface circuit based on SJA1000 and the Ethernet interface circuit based on DM9000A are selected. The suitable sensor design and detection circuit is selected to measure the important thermodynamic parameters such as temperature, pressure, rotational speed and so on. A suitable signal acquisition circuit is designed to collect these data in order to realize the real-time monitoring of the running state of marine power equipment. The SOPC system based on Nios II soft core processor is developed on FPGA controller, which is used to control the running of the whole hardware platform of the lower computer. In the Quartus II development environment, the FPGA subprogram is edited. The self-defined IP module is developed with VerilogHDL language to realize real-time communication with each peripheral module. The PCI9054 driver is designed by using the WDM model driver under the Windows environment, which realizes the plug and play of the device, and develops the monitoring and fault diagnosis application software of the system in the VS2008 environment. Finally, This paper presents the design idea of neural network fault diagnosis expert system for marine power plant.
