【摘要】：在過(guò)去的幾年里,中國(guó)江河航道正進(jìn)入一個(gè)“數(shù)字航道”的時(shí)代。作為數(shù)字航道發(fā)展的突出成果,航道綜合監(jiān)控系統(tǒng)在很大的程度上提高了航道管理的效率。但是就目前而言,絕大部分的航道綜合監(jiān)控系統(tǒng)都是基于PC端的,難以適應(yīng)高速發(fā)展的移動(dòng)互聯(lián)網(wǎng)。針對(duì)這個(gè)問(wèn)題,本文研究并開(kāi)發(fā)一個(gè)基于Android平臺(tái)的航道綜合監(jiān)控系統(tǒng),將航道監(jiān)控管理功能從PC端遷移到手機(jī)或平板電腦的移動(dòng)設(shè)備端,從而可更好地借助移動(dòng)互聯(lián)網(wǎng)的優(yōu)勢(shì)與便利,將航道監(jiān)控任務(wù)從單一的監(jiān)控中心分散到所有的航道工作船和工作人員,簡(jiǎn)化內(nèi)河航道管理流程,提升靈活性和效率。本文研究的系統(tǒng)包括一個(gè)前端應(yīng)用App及其后臺(tái)服務(wù)器程序,APP以電子航道圖為基礎(chǔ),通過(guò)移動(dòng)網(wǎng)絡(luò)或者無(wú)線WIFI可實(shí)時(shí)地獲取后臺(tái)服務(wù)器提供的航標(biāo)、水位以及船舶動(dòng)態(tài)信息,實(shí)現(xiàn)航道的動(dòng)態(tài)監(jiān)控。歸納起來(lái),完成的主要工作如下：(1)基于RESTful Web Services,采用多層級(jí)的架構(gòu),設(shè)計(jì)了系統(tǒng)的總體架構(gòu)和后臺(tái)服務(wù)接口。(2)設(shè)計(jì)并實(shí)現(xiàn)了客戶(hù)端APP,包括電子航道圖的顯示與更新,船舶、航標(biāo)的動(dòng)態(tài)顯示和查詢(xún)、航標(biāo)異常報(bào)警以及水位實(shí)時(shí)及歷史數(shù)據(jù)查詢(xún)和標(biāo)繪等功能。(3)深入研究了水深動(dòng)態(tài)修正算法。該算法依據(jù)相鄰最近的水位站水位數(shù)據(jù),基于距離加權(quán)方法實(shí)時(shí)地對(duì)航道圖上的水深進(jìn)行動(dòng)態(tài)修正,算法計(jì)算簡(jiǎn)單,并具有較高精度和實(shí)用性。本文研發(fā)的系統(tǒng)已經(jīng)在長(zhǎng)江下游部分河段應(yīng)用,應(yīng)用結(jié)果表明移動(dòng)航道監(jiān)控的形式深受航道管理部門(mén)的喜愛(ài),它也將成為下一代數(shù)字航道建設(shè)的重要內(nèi)容。
[Abstract]:In the past few years, China's river channel is entering the era of "digital channel", as a prominent achievement of the development of digital channel. The waterway integrated monitoring system improves the efficiency of waterway management to a great extent, but at present, most of the waterway integrated monitoring systems are based on PC. It is difficult to adapt to the rapid development of mobile Internet. In view of this problem, this paper studies and develops a waterway integrated monitoring system based on Android platform. The waterway monitoring and management function is transferred from PC to mobile device of mobile phone or tablet computer, so as to make better use of the advantage and convenience of mobile Internet. Dispersing the waterway monitoring task from a single monitoring center to all waterway working vessels and staff to simplify the inland waterway management process. The system studied in this paper includes a front-end application App and its back-end server program app based on the electronic channel diagram. Through the mobile network or wireless WIFI can real-time access to the background server provided by the navigation mark, water level and ship dynamic information, to achieve the dynamic monitoring of waterways. The main work accomplished is as follows: 1) based on RESTful Web Services, a multilevel architecture is adopted. Design the overall architecture of the system and backstage service interface. 2) designed and implemented the client APP, including the display and update of electronic channel map, the dynamic display and query of ship and navigation mark. The algorithm of dynamic correction of water depth is deeply studied. The algorithm is based on the nearest water level station water level data. Based on the distance weighting method, the dynamic correction of the water depth on the channel map is carried out in real time. The algorithm is simple, accurate and practical. The system developed in this paper has been applied in the lower reaches of the Yangtze River. The application results show that the form of mobile channel monitoring is popular with the waterway management department, and it will also become an important part of the next generation digital waterway construction.
