The Design Of Intelligent Gas Meter6中英文翻译.docVIP

The Design Of Intelligent Gas Meter Gas meter is a gas flow meter; they are included in the national directory of strong compulsory seizure test measuring instruments. Gas metering system has been developing constantly. From unenlightened mechanical to intelligent nowadays, made peoples lives has been facilitated. In the past for a long period of time, we use most of all mechanical in the international, with the continuous advancement of electron technology, electron-type gas meter have also emerged in other country, but there is still a lot of non-convenience. Currently mechanical gas meter give a great deal of inconvenience to management and users, that is, issue of meter reading. We take original backward artificial way to look-up table charges generally. This charging method has several major disadvantages: occupy a great deal of manpower; Many drawbacks of artificially; inefficient and created a great waste of human, material, time to manage department. Therefore, research and development a new type of gas meter charging system is necessary. Abroad, intelligent gas metering system is also developing, and they have automatic billing, as well as alarm function, to protect the benefits of the Gas Company and the users. In China, Gas Meter remains at a fairly low level, most of the products just to play a role of switching, and the development of intelligent table also stagnated at a very low level, although there are a lot of manufacturers to product the intelligent gas meter. However, very few sophisticated products; they improve the products on the basis of foreign technology according to the actual situation, mostly the use of IC card technology. and manufacturers can not be simultaneously large quantities of products. In the view the actual situation, we reference to already exist product, according to the idea of it, and to design the intelligent gas meter. the system of the intelligent have application of advanced IC card billing functions, use of the remote
