摘要：In this paper, in order to manage and use the city's water resource reasonably, a wireless monitoring system for water supply based on ARM 11 microprocessor is designed for metropolitan city . This system uses ARM 11 microprocessor of low power and high performance as the main chip, and designs software with ¦Ì C/OS-II real-time operating system to achieve remote real-time monitoring for water consumption of enterprises. The system will use ZigBee and GSM through GPRS system for communication protocol. The ZigBee is used since the application don't need high speed data rate, need to be low powered and low cost. Each ZigBee node will be connected to the collector node and from collector node the data will be sent to the central computer by using GSM through GPRS.GSM network with its vast coverage in most countries and also its competitive ever growing market, is becoming popular as a medium for machine to machine applications which utilize the GSM network to send its water usage reading using short message service back to the energy provider wirelessly. In addition, during the debugging process, the electromagnetic flow meter has non -linear output because of interference by a strong current , so this system uses the first order Taylor expansion for the working point in order to linea rization. In a word, this system avoids the work method of the traditional meter-reading and reduces water waste to a certain extent.
