The Chain Gas Station' Data Automatic Collection And CPU Card Management System

To adapt to the change of inside and outside situation after China joined into WTO,and to improve the gas station's management level and work efficiency,gas station should carry out the chain-working fashion. To realize this purpose,we develop a set of computer management system-the chain gas station CPU card management system. Aim to improve the gas station's management level,this system uses the CPU card as its core,fully express CUP card's specialty-high security,use CPU card to replace the handwork charge work. This system is composed of management center system and gas station management system. The gas station management system mainly realize the distribution of CPU card,the input,sale and storage of gas station's oil business,and send the business affair to management center;management center system mainly realize the CPU card's fabrication,publish,and gather the gas station's data,so as to find out the gas station's situation and make scientific decision in time.To solve the problem existing in charge work section,and exhaust the leakage in management,this system provides the oil machine's data automatic collection function. This system uses a set of self-made data collection equipment to realize the communication between computer and oil machine. In the process of system design,this system fully consider the flaw of oil machine and the interference of oil machine's working place,take many necessary measures,imply the electronic oil machine's data's automatic collection successfully,improve the gas station's work efficiency,and realize the gas station's automatic management effectively.
