Description
technical field [0001] The invention specifically relates to an IC card-wireless signal conversion device, a conversion method and a water meter made thereof. Background technique [0002] With the improvement of people's living standards, automation and unmanned has become one of the directions for the future development of society. [0003] As the most important component and the only metering element in the water metering system, the water meter assumes the important role of metering the user's water consumption and uploading metering data. At the same time, with the development of wireless communication technology, wireless remote water meters are becoming more and more popular among users. Wireless communication can greatly reduce wiring costs, make installation and maintenance easier, and solve the problem of difficult and unfavorable management of water meters. [0004] However, since there are still a large number of old-fashioned wired IC card water meters, these ...
