[Abstract]:General packet Radio Service (GPRS(General Packet Radio Service) makes the mobile market of mobile communication and data network become a single IP service. At the same time, the mobile network has the ability to provide more value-added services. The design of micro-power B-band wireless modules and antennas in accordance with the regulations of the National Radio Commission has a bright future and broad development space, accompanied by the implementation and promotion of smart homes and intelligent cities, Intelligent public utilities, which are closely related to people's livelihood, are facing a period of rapid development, especially the automatic Meter reading system (AMR automatic Meter reading) system, which is strongly supported by national policies. The data acquisition terminal based on wireless network will be one of the key guarantee for the implementation of AMR system, and the AMR data transmission system based on wireless network is an important part of intelligent home and intelligent city. The concept of wireless network and AMR system, Secondly, the key technologies of GPRS network and micro-power wireless network for AMR data transmission are described. The overall design, module design and software design of AMR data transmission system based on GPRS and B-band wireless network are emphasized. The AMR data acquisition and transmission system based on wireless network is realized and applied to the field. The practical results show that the data transmission of the AMR system is accurate and reliable. The main work of this paper is to introduce the characteristics of GPRS network and the concept of AMR system. The key technology of GPRS network and micro-power wireless network used for AMR data transmission is described. A 433MHz B band micro-power wireless module and antenna are designed, and the data acquisition terminal of wireless transmission, which is based on wireless communication technology, is realized. In order to adapt to different application environment, we design and implement wireless data monitor terminal. 5) to adapt to complex field application environment, we design and implement a collection terminal based on 900MHz / 1800MHz GPRS/SMS data communication. In order to improve the problem of poor network communication in the remote transmission meter reading system of public utilities, this paper designs and implements the 10 level forwarding mechanism of the collection terminal, and implements the wireless data centralized reading meter of water meter, gas meter and heat meter.
