【摘要】：電動汽車的廣泛推廣,帶動了充電服務(wù)需求的快速增加。隨著新版電動汽車國家標(biāo)準(zhǔn)的出臺,類型眾多的充電接口終于趨于統(tǒng)一。如何實現(xiàn)不同品牌電動汽車充電業(yè)務(wù)在標(biāo)準(zhǔn)接口上的兼容,實現(xiàn)充電服務(wù)系統(tǒng)的通用性是當(dāng)前研究的重點。同時,充電自助服務(wù)業(yè)務(wù)也并沒有系統(tǒng)性開展。因此,本文將面向電動汽車充電服務(wù)的通用性和自助化,對電動汽車自助充電通用服務(wù)系統(tǒng)進(jìn)行了詳細(xì)的設(shè)計。本文首先對電動汽車充電服務(wù)系統(tǒng)的國內(nèi)外研究現(xiàn)狀進(jìn)行分析,并以當(dāng)前市場上的充電接口著手,提出電動汽車服務(wù)的相關(guān)需求。本文提出了由充電服務(wù)云服務(wù)器、智能充電樁和自助服務(wù)手機(jī)客戶端APP三個子系統(tǒng)所組成的包括感知層、傳輸層和應(yīng)用層的自助充電通用服務(wù)系統(tǒng)的總體設(shè)計方案,并對各子系統(tǒng)進(jìn)行了詳細(xì)的設(shè)計。系統(tǒng)具有監(jiān)控管理、交易管理、信息采集管理、運(yùn)行工況分析及系統(tǒng)管理等功能。系統(tǒng)的各項業(yè)務(wù)在各個分層間分步執(zhí)行,整體管控,提高了系統(tǒng)整體性能和整體穩(wěn)定性。同時本文還對系統(tǒng)的通信網(wǎng)絡(luò)及安全保障進(jìn)行設(shè)計,保證系統(tǒng)安全可靠的運(yùn)行。其次,針對未來復(fù)雜多樣充電業(yè)務(wù)在CAN總線上的通用兼容問題,本文從服務(wù)器與充電樁及電動汽車等充電設(shè)施服務(wù)系統(tǒng)間的外部接口和自助服務(wù)手機(jī)客戶端APP與服務(wù)器之間的用戶接口兩方面對接口間的通信協(xié)議進(jìn)行研究。系統(tǒng)設(shè)計了符合CAN協(xié)議的充電服務(wù)中外部接口的報文格式和數(shù)據(jù)結(jié)構(gòu),并采用JSON數(shù)據(jù)規(guī)約的用戶接口,為系統(tǒng)間承載的各項業(yè)務(wù)數(shù)據(jù)提供了通用的通信通道。通過對系統(tǒng)接口的規(guī)范化設(shè)計,系統(tǒng)實現(xiàn)了對當(dāng)前CAN總線接口的兼容性和服務(wù)的通用化。本文還對自助充電服務(wù)手機(jī)客戶端APP進(jìn)行了詳細(xì)設(shè)計。自助充電服務(wù)APP是用戶參與充電服務(wù)的唯一前端。為實現(xiàn)充電服務(wù)的自助化,本文對APP的結(jié)構(gòu)、功能及地圖功能模塊,業(yè)務(wù)狀態(tài)模塊、充電支付模塊、充電控制模塊、查詢模塊等各功能模塊進(jìn)行了詳細(xì)的設(shè)計及界面展示。最后綜合各類模塊的功能,本文基于模糊規(guī)劃法設(shè)計了手機(jī)APP一鍵導(dǎo)航功能,綜合充電站距離、充電等待時間、電動汽車耗電量及充電站負(fù)荷等各類數(shù)據(jù)分析最優(yōu)的充電樁選擇方案。通過多元化及智能化的手機(jī)APP設(shè)計,用戶可以實現(xiàn)遠(yuǎn)程預(yù)約、自助控制及快捷支付等各項功能,實現(xiàn)系統(tǒng)的自助服務(wù)需求。通過對充電系統(tǒng)各部分的詳細(xì)設(shè)計,本文實現(xiàn)了充電服務(wù)的自助性及通用性等問題,系統(tǒng)的應(yīng)用將對電動汽車充電業(yè)務(wù)的廣泛推廣具有積極意義。
[Abstract]:The wide promotion of electric vehicles has led to a rapid increase in the demand for charging services. With the introduction of the new national standard for electric vehicles, many types of charging interfaces finally tend to be unified. How to realize the compatibility of charging services of different brands of electric vehicles in the standard interface and the universality of charging service system is the focus of current research. At the same time, charging self-service business is not systematic. Therefore, this paper designs the general service system of electric vehicle self-charging in detail, which is oriented to the universality and self-service of electric vehicle charging service. In this paper, the research status of electric vehicle charging service system at home and abroad is analyzed, and the related requirements of electric vehicle service are put forward based on the charging interface in the current market. This paper presents the overall design scheme of the self-charging general service system, which is composed of three subsystems: charging service cloud server, intelligent charging pile and self-service mobile phone client APP, which includes perception layer, transport layer and application layer, and designs each subsystem in detail. The system has the functions of monitoring and management, transaction management, information collection and management, operating condition analysis and system management. The business of the system is executed step by step among the layers, and the overall control is improved, which improves the overall performance and stability of the system. At the same time, the communication network and security of the system are designed to ensure the safe and reliable operation of the system. Secondly, aiming at the general compatibility of complex and diverse charging services on CAN bus in the future, the communication protocol between the interface is studied from two aspects: the external interface between the server, the charging pile and the charging facility service system, and the user interface between the self-service mobile phone client APP and the server. The message format and data structure of the external interface in the charging service in accordance with CAN protocol are designed, and the user interface of JSON data protocol is adopted to provide a general communication channel for the service data carried between the systems. Through the standardized design of the system interface, the system realizes the compatibility of the current CAN bus interface and the universality of the service. This paper also designs the self-charging service mobile phone client APP in detail. Self-charging service APP is the only front-end for users to participate in charging services. In order to realize the self-service of charging service, the structure, function and map function module of APP, service status module, charging payment module, charging control module, query module and other functional modules are designed in detail and the interface is displayed in this paper. Finally, based on the fuzzy programming method, the APP one-button navigation function of mobile phone is designed, and the optimal charging pile selection scheme is analyzed based on the distance of charging station, charging waiting time, electric vehicle power consumption and charging station load. Through the diversified and intelligent mobile phone APP design, users can realize the functions of remote reservation, self-control and fast payment, and realize the self-service requirements of the system. Through the detailed design of each part of the charging system, the self-service and universality of the charging service are realized in this paper. The application of the system will be of positive significance to the extensive promotion of the charging service of the electric vehicle.
