The Application Of Fieldbus And Study Of The Integration Of Management And Control

In order to enhance the technology of gas station, the management and economy of petroleum' sell, now more and more oil firms want to use the managing system based on IC card which it can raise the compete ability on market. Using the system it can achieve the management with scientist and modernization for petroleum' sell. Through using IC card replace cash and oil-ticket, and link with greaser that controlled by computer, we can build an auto sale-oil-system based on IC card that integrate the management of gas station' information and company's.After discusses the typical Fieldbus simply, it introduces the LonWorks Fieldbus and the design of intellectualized controls based on Neuron chip, and then we build a control system. On the base of control system, we use the MES(Manufacturing Execution System) and ERP(Enterprise Resources Planning) to control and manage the system, build a system Integrate of management and control based on IC card.The gas station based on net-system is distributed structure. It can sell oil single or many gas stations link with manage computer that build a system. The petroleum company has many gas station can build their own sell-oil system based on city. Every greaser has an IC card reader, so the driver can pay for the oil with IC card, and the measure department can examine some measure parameters and the precision of greaser. For the users, they can buy oil facility at every gas station that linked with each other. Like this, it can form a changeless consumer, at the same time; eliminate the trouble of giving change. After the gas station and the petroleum company used the system Integrate of management and control, it can enhance the management; see the work status of every station in time. Then it can gather the system's data through net, and provide information in effect for scientific analysis. All that can provide exact data for management and make the system efficiently.
