| With the approaching of information society, sorts and amount of information which human being owned increase explosively, IC-a kind of convenient, safe and reliable information carrier which contains high technology and high value-added spring up. Due to its wide applied field and vast product market, IC technology becomes the hotspot issue in the field of information industry in recent years. Meanwhile, artificial copying meter is a main form in management system of gas charge for a long time in our country. There are many disadvantages in old management system. For example, much work, difficult charge, lower efficiency and mistake often arise. In order to reduce the waste of manpower and material resource in gas management and to reduce unsafe factors, This project does research on Intelligent card and gas meter control device which is the further explored to the practical application of IC technology and is also a reform in management system of gas charge.This project makes theoretical analysis and does technological applicable research on the structure, function and demand of technology on control device of IC for gas meter. According to the principle of lower cost, higher reliability, the design completes much work. The contents of project are as follows:(1) PIC Micro-controller which is lower-power and lower price is the core of control device .The whole circuit realizes the functions of collecting pulse, keeping data, driving electric machinery valve, reading and writing IC, detecting power supply, sound alarm and liquid crystal display.(2) The theory of fuzzy control resolves the control of electric machinery valve. The software design that is the module structure realizes the function of gas meter counting, inquiring and dealing with the malfunction.This device can also apply to electric meter, water meter, and other intelligent counting control device as IC. If this device is improved at the base of formerly device, it will possess economical and applied characteristic.Candidate: Yu XiuliSpeciality: Electrizationand automatizationof Agriculture Supervisor: Prof. Ouyang Binlin... |
