An AMR system based on CC2420 is designed. The hardware structure of system employs distributed structure based on wireless sensor networks, which consist of measure meters, sensor node, data collectors, server and wireless communication network. The tree network topology was adapted in designing system. For a short distance transmission, the data collectors collect data from the meter sensors using the ZigBee communication. For a long distance transmission, from the data collector to the server, system uses TCP/IP protocols. The ZigBee technology enhances the flexibility and the practicality of AMR system. Key Words: Automatic meter reading system, ZigBee technology, Remote Measurement. 1. INTRODUCTION Automatic meter reading (Automatic Meter Reading) system is used to telemeter the consumption of electricity, gas, water, liquid, oil and steam, since the direct physical access or visual reading of meters are very inconvenient. There are many problems in existing AMR system.[1] The AMR system can be divided into two kinds according to communication medium; they are wired AMR system and wireless AMR system. The cost and difficulty of wiring are increased when adopting wired AMR system, meanwhile the agility is failed so the wired AMR system is limited to an extend and apply. The wireless AMR system has congential superiority relative to the wired AMR system because it adopts advanced wireless communication technology.[2] Wired AMR system adopts RS485 bus and electric power carrier wave. The system based on RS 485 is simple and easy to install. But it has limited no of nodes. Hence it is not suitable for large scale AMR system. The stability and reliability of power carrier wave base AMR system very low [2]. The wireless system based on GSM/GPRS is popular. But the fee of using GSM/GPRS network is needed, and the cost of hardware system is very high. In this paper we present a remote AMR system based on wireless sensor network. In this system Zigbee technology which works in international free frequency segment and processes self organization function is adapted to solve the problem in existing meter reading system. The structure of system employs the distributed structure which consists of measure meters, sensor nodes, data collectors, server and wireless communication networks. For a short distance transmission, the data collectors collect data from the meter sensors using Zigbee communication. For long distance transmission from the data collectors to server system uses TCP/IP protocol. The collector is designed in software. The data collector is used for protocol conversion from Zigbee protocol to TCP/IP protocol before transmission. The system proposed in this paper has many significant excellences, such as networked wireless International Journal of Engineering Research & Technology (IJERT) Vol. 1 Issue 4, June - 2012 ISSN: 2278-0181 1 www.ijert.org
