【摘要】：LNG(液化天然气)作为清洁的燃料,它的生产与使用,对改善城镇生态环境和改良城市能源架构,促进环保产业发展有着重大意义。LNG加气站投产耗时短,能够快速满足能源需求。在我国经济发达、能源紧缺的沿海中小城市,已经建成许多LNG加气站解决城市供气。在LNG行业,许多燃气公司仍然在使用传统手工作业的方式,生产效率极低,也不方便公司内部对加气站的生产管理,在公司财务统计方面也变得繁琐、复杂,还加大了错误的发生机会。LNG加气机网络管理系统就是针对这个问题而研发的,主要采用了C/S架构,系统使用了网络、数据库、IC卡、RS485技术,该系统的使用,将提高燃气公司的生产效率,方便公司对下属各加气站的管理和监控。LNG加气站将分别安装站点监控软件和IC卡管理软件,LNG站点监控软件实时地采集加气机显示的数据,单价、气量、金额等数据,方便了站点对售气数据的统计。而IC卡管理软件的使用,可以用刷卡消费代替现金消费,无论是对公司还是司机个人都有益处。在此基础上,公司可以把下属的所有加气站、充值点进行联网,让加气数据、充值数据实现交互,方便了对IC卡、加气站的一体化管理。本文所设计的LNG加气机网络管理系统是典型的网络信息化管理系统,包括站点监控软件、客户端通信软件、服务器通信软件、IC卡管理软件、中心查询软件。主要内容为:1.系统设计:阐述软件系统设计的设计思想,基本原则。对系统进行构架设计,网络拓扑设计,通讯方式选择,硬件选取。开发工具的挑选,数据库挑选,数据的结构设计,软件模块组成等。2.IC卡管理软件设计:实现IC卡基本管理功能:登录、登记、发卡、充值、清卡、改卡,挂失、补卡、注销、查询、统计等基本功能设计。3.站点监控系统设计:实现登录,操作员管理,监控界面,班组累计,信息查询,统计报表,数据库维护等功能设计。
[Abstract]:LNG (liquefied natural gas) as a clean fuel, its production and use, to improve the urban ecological environment and improve the urban energy structure, promote the development of environmental protection industry has a great significance. A lot of LNG filling stations have been built to solve the problem of urban gas supply in small and medium-sized coastal cities with developed economy and energy shortage. In LNG industry, many gas companies are still using the traditional manual operation method, the production efficiency is extremely low, and it is not convenient for the production management of the gas filling station inside the company, and the financial statistics of the company also become complicated and complicated. The network management system of LNG aerator is developed to solve this problem. It mainly adopts the C / S structure, the system uses network, database, IC card RS485 technology, the use of the system. The production efficiency of the gas company will be improved, and it will be convenient for the company to manage and monitor the stations under its control. LNG filling stations will install station monitoring software and IC card management software respectively. The LNG station monitoring software will collect the data displayed by the gas dispenser in real time and the unit price. Gas volume, amount of data, facilitate the site to sell gas data statistics. The use of IC card management software, can use swipe card consumption instead of cash consumption, whether for companies or drivers of personal benefits. On this basis, the company can all the subordinate filling stations, charging points for networking, so that the aeration data, recharge data to achieve interaction, facilitate the IC card, gas station integration management. The network management system of LNG aerator designed in this paper is a typical network information management system, including site monitoring software, client communication software, server communication software, IC card management software, central query software. The main content is: 1. System design: describes the design idea and basic principles of software system design. The system architecture design, network topology design, communication mode selection, hardware selection. Development tool selection, database selection, data structure design, software module composition, etc. IC card management software design: achieve IC card basic management functions: login, registration, card issuance, recharge, clear card, change card, report loss, fill card, write off, Query, statistics and other basic functions design. 3. Site monitoring system design: implementation of login, operator management, monitoring interface, team accumulation, information query, statistical reports, database maintenance and other functions.
