Design And Implementation Of Remote Monitoring System For Ship Oily Water Separator Operation Status

With the more and more importance of shipping in international trade, shipquantity and tonnage is becoming bigger. Meanwhile, ship anti-pollution has beenpaid more attention. Oily water will be generated during ship operation, and bilgewater is the main source of oily water. Generally, oily water is processed by oilywater separator firstly, and it will be discharged out in legal area if the processedwater could meet relevant standard. According to investigation and read relevantinformation, it is frequent that bilge water is discharged into water area directlywithout the processing of oil water separator. Therefore, it has great theorysignificance and utility value to develop an effective monitoring system for oily waterseparator.The monitoring system for oily water separator proposed by this paper canrealize remote supervision to oily water separator, and recognize illegal dischargebehavior of bilge water. It can improve the informatization and intelligentization ofoily water separator supervision of maritime administrator. The main work issummarized as follows:1) Overall design of water separator monitoring system has been proposed.Based on the analysis of system requirements, the design of system framework, oilywater separator shipborne monitoring terminals, information transmission and remoteinformation management system are proposed.2) Shipborne monitoring terminal has been designed. On the basis of shipboardterminal requirement analysis, the circuit of the terminal is designed, including MCUminimum system, acquisition unit, storage unit, communication unit, isolationmodule, display design module and GPS module. Simultaneously program processesof functions are described which include the A/D data acquisition, datacommunications, SD card storage, LCD display, GPS parsing and historical datacomputing and storage.3) Data transmission scheme has been studied. In actual applicationenvironment, by analyzing and comparing kinds of transmission means, the AIS transmission is selected as the means of the system communication. The appropriatecommunication protocols are designed to realize the information interaction inaccordance with NEMA0183protocol.4) Remote management system has been designed. According to systemfunctional requirements, the system interface design, database design and functionalrealization, including static information display, real-time monitoring and alarming,historical data query, interactive information display and query have been completed.5) A set of running water separator judge algorithms have been proposed. Theymainly include oil calculation algorithm, every12h water separator on-off algorithmand alarm recognition algorithm of oily water separator.6) System testing has been completed. In a laboratory environment terminalperformance testing, performance testing remote information management systemsand communication reliability testing were tested. The test results show that thesystem can realize research objectives and functions of the preset.The remote monitoring for Ship Oily Water Separator Operation is realized inthis paper, and the supervision and efficiency to bilge water illegal discharge behaviorare improved. To some extent, the development of ship informatization and maritimemanagement is driven by this paper.
