Description
Technical field
The invention belongs to water meter processing technique field, relate to passive and wireless collection and copy water meter.
Background technology
China's water resource is very short, and social and economic water consumption safety guarantee has become the key factor of restriction Chinese society economic development.Solve water resources problems extremely urgent, water saving the most feasible current, one of measure the most efficiently beyond doubt.The research application of wireless remote transmission intelligent water meter is significant thus.Intelligent wireless remote transmission water meter system be utilize gage probe, wireless data transmission technology and Intelligent Single-Chip Based control technology to combine a kind of long-distance metering, observing and controlling, reading transcribing system, be the management system realizing water supply industry water resources management, water meter copy reading, water rate automatic management of charge, digitizing, networking.With regard to traditional mechanical water meter, radio remote transmitting water meter charging is accurate, not easily steals water.Along with the development of radiotelegraphy, mechanics of communication and singlechip technology, wireless intelligent remote-transmission water meter system is installed facility with it, safeguards fast, by advantages such as installation environment and wiring restrictions, is become the leading system of water meter industry intelligent management.Again in conjunction with computer technology network technology, infotech, management benefit can be improved.Along with the maturation of the development of chip technology and the maturation of frequency hopping, particularly wireless network protocol and wireless network, frequency hopping and radio network technique can be utilized to realize wireless long-distance meter-reading.Current wireless network has started application abroad successively, believes that radio network technique also can start application in China and popularize in the near future.Wireless data transmission network also can cover every nook and cranny as GSM network.
