Gas Station Synthesis Information Management System

1.IntroductionThe petrochemistry enterprise is our country's pillar industry, for should to jointhe challenge which WTO and the economical globalization brings, achieves theChinese petrification product oil retail sales system Electronical goal, uses theadvanced electronic information technology, entered, sells, pays,memoriaze the lineof automated management to the gas station the request already extremely to beurgent. Therefore establishes a standardized scientific style government by law gasstation synthesis information management system to have the vital significance tothe petrochemistry enterprise's development.This article according to this kind of demand the management systemmanagement system to carry on the software and hardware design to the gas stationstation in, and has constructed the gas station system administration platform usingthe VB language, has realized the automated management which the entire gasstation entered, sells, pays, saves. Achieves the daily data date clear, the monthlysettlement, each kind of report form automatic production, realizes to theaccelerator, the fluid position meter real-time monitoring, importantly enters, sells,pays, the balance according to the real-time inquiry, causes the function departmentpromptly accurately to keep abreast of the refined oil sale situation, fundamentallyhas complex solved complex, the arduous data statistical work, causes it to changeaccurately, quick, is convenient, the working efficiency greatly enhances, hasprovided the management decision-making important data for the superintendent,raises the management level greatly.2.This article main research contentIn this article mainly studied the gas station to stand the data acquisition andthe correspondence,Gas station management system management system functionmodule as well as gas station management system management system softwaredesign and so on three aspects contents,Under has made the specify to these threeaspects2.1 gas stations information management system designThe topic research goal is designs one kind to adapt China Petroleum andChemical Corporation's gas station synthesis management system managementsystem,Uses in changing the current gas station technology to be backward,manages the efficiency low aspect. We understood also pauses to the majority ofservice stations in the manual management level, no matter is refuels data gathering,the record, the oil quality enters, sells, saves the statistics, the amount settlesaccounts, perhaps the unit oil used management, and the receipt, the receipt draw upmajority of manually completes, this also is our common metropolis landscape is infront of the gas station lines up the long line to solve this malpractice, has designedthe gas station and user's demand analysis in view of this present situation,Hasplanned the gas station software management function,Has listed the functionmodule which this system must realize,The data acquisition system hardwaredesign and the gas station management system management system software designhas assigned the goal for the following station in.We the systematic main function module will divide into two kinds. A kind isthe gas station management partially includes: The system registers, the statisticalreport form, the bookkeeping management, the reference report form and so on fourmodules. Another class number partially includes according to gathering: Dataacquisition, data inquiry, data input and so on three modules. The third kind is thesystem maintenance part. In2.2 stands the data acquisition and the correspondenceIn the gas station stands mainly is by the accelerator, the oil tank and the fluidposition meter is composed, uses the RS485 agreement network, completes the dataacquisition and the exchange;The provinces and cities higher authority corporatemanagement, various gas stations management system management system and theserver long-distance register the network, completes the information to compile themanagement function. In the station corresponds the main duty is comes from theaccelerator and the oil pot time real number according to gathers in, gives stands theinformation management platform. Realizes this to continue the task is called thecommunication controller the network equipment. Uses his reason is a main enginecannot and the multi-Taiwan fluid position meter direct communication.2.3 gas stations management system management system softwaredesignThe gas station management system management system materially is arefined oil material software core. Altogether has three big primary missions: First,enters, sells, pays, saves the service regarding the station in to carry on themanagement. Second, regarding comes from the accelerator and the oil potreal-time information carries on the collection to save and to produce the servicereport form. In third, will stand will synthesize the information promptly to reportthe higher authority department responsible for the work through the male net.Three big functions like charts 2.1 functional diagrams:Fig 2.1 systems functional diagramsThe software design besides completes the above function also to be supposed to have theconsummation to protect oneself the function, the self-maintenance function, the dataredundant backup function and so on. The software perfect degree has the direct influence to thesystem application value. This chapter narrates is we uses VISUAL BASIC to compile a seriesof men-machine operation contact surface and the utility program process. Also described thesystem database foundation process.The management system management system software may inquire and receive the gasstation through the communication controller by the serial communication way the hardwaregatheringaccelerator oil potinformationfunctionIn thestationenters,sells,saves themanagemWith igherauthorityinteractiveinformatiofunctioninformation and the equipment condition, and can send out the control command to it, carrieson the control to it. Considered completes to the communication cost system and the higherauthority department's correspondence through the male net. After analyzes us to know the gasstation internal service content includes:(1) Enters, the refined oil purchases (calls in) the total quantity, refers to the gas station topurchase (non-independent calculation from the responsible company to refuel calls in forinterior) the gasoline, the diesel oil, the petroleum, the lubricating oil, the lubricant, and otherpetroleum products (abbreviation refined oil) total quantity.(2) sells, the refined oil sale total quantity, refers to the gas station through way sale theand so on the cash, check, idea account refined oil total quantity.(3) pays, namely refuels the total quantity, refers to the gas station through the acceleratordirect sale steam, the diesel oil total quantity.(4) saves, the stock total quantity, refers to the right to the ownership of goods to be thegas station the refined oil quantity. Outside including checks keeps in stock, including has notsold has not proposed the number.(5) sales income statistics, refers to the gas station foreign sale refined oil the income.(6) sales cost statistics, refers to the gas station foreign sale refined oil to enter the pricecost. (Or wholesale price) calculates according to responsible company's internal Adjustmentprice(7) Gross profit statistics, reflection above sale income deduction sale cost difference.This system altogether has nine stature modules, together with registers the module altogetherten modules.3 summaryIn this article realized has stood the first floor network constitution, has carried on thehardware design, the software design, the antijamming design to the communication controller.Tries the movement through the actual gas station, the overall system design has realizedaccelerator information gathering real-time;Report form production automation;Data storagesafity;Intelligence transmission netful, has realized the gas station synthesis managementfunction, believed will be able to be able to have not the small help to the later gas stationsynthesis management domain. Because the overall system development work load is extremelybig, therefore the system development work is completes in under the development group'scooperation. I have undertaken the massive work in the system development, includingcommunication controller hardware design, hardware debugging;Hardware system monolithicintegrated circuit assembly program establishment;Management system management systemmain engine under Windows serial mouth signal procedure establishment;In as well as themanagement system management system main engine, the communication controller, theaccelerator, between the fluid position meter data communication connection and the debuggingwork, stood the management system management system to the gas station in to make thesoftware design,Language has constructed the system management software using VB as wellas Micorsoft the Access,And passed through several month-long scene debuggings, the printingreport form, customer basic satisfaction, has realized gas station synthesis data storage netfulIntelligence transmission netful , has realized the gas station synthesis management function...
