This paper is concerned with automatic telemetering system which reads the consumed quantity of electricity, gas, and piped water. The existing metering method such that a meterman visits households and directly reads meters can cause several problems, including violation of privacy and the possibility of criminal accident, as well the inefficiency in viewpoint of system operation and rate notification. In this paper, we propose a new automatic telemetering and rate notification system, in which the system reads several meters at remote locations and notifies the rates to the customer's cellular phone with short message service(SMS). The proposed system has been developed by using CDMA mobile communication modules and personal computers. This system can operate only with cellular communication network even without wired-internet facilities. In particular, the developed system can provide home security and convenience as well as cost reduction, and thus be applied to intelligent home networks.

Meter reading system, operated by meter staff who reads the meter and record consumption with handhold data terminals. can cause privacy intrusion, unread meter data, abnormal readings and excessive expenses of maintaining the system. To prevent the deterioration of customer service quality, Automatic Meter Reading system, which automatically recognizes meter readings and transmit reading data through wireless RF module, is designed. From collecting the reading data to managing statistics of customer's consumption information. this automatic meter reading system provides more accurate and fast information to customers. By designing this system, customer service satisfaction and reliability can be improve

전력선통신을 이용한 원격검침 시스템의 구축이 시범사업을 넘어 상용화 수준으로 확대되어가고 있으나 현재까지는 주로 주상변압기에서 댁내 수용가정간에 고속전력선 통신칩을 사용하여 셀 토폴로지형태로 100가구전후 원격검침망을 구성하였다. 지중구간의 전력선은 가공선로와는 많은 다른 통신채널 특징을 가지며 지중화된 구간은 대도시 밀집지역에 주로 시설되기 때문에 원격검침시스템 구성시 가공구간보다 경제적인 측면에서나 검침자동화 확산 측면에서나 좋은 효과를 볼 수 있다. 본 논문에서는 지중고압선을 경유하는 원격검침망의 모델을 설계하고 시범운영을 통해 성능을 시험하였다.

국내의 원격검침 데이터는 주로 전력요금 산출용도에 활용되고 있다. 하지만 국외 전력회사들은 미래 디지털 사회의 기반이 되는 신 전력시스템을 구현하는데 필요한 핵심기술 중의 하나로서 IT(Information Technology)기반 전력부가서비스 기술의 중요성에 대해 강조하고 있으며, 이를 위해 원격검침 데이터를 기반으로 하는 다양한 전력부가서비스를 개발하여 적용하고 있다. 따라서, 국내의 경우도 원격검침 데이터를 단순한 전력요금 산출용도가 아닌 전력소비자와의 관계에서 부가가치를 높일 수 있는 무한한 잠재력을 지닌 전략적인 자산으로 보고, 원격검침 데이터 가공 및 활용기술의 선진화를 통하여 전력회사와 전력소비자 모두에게 필요한 전력부가서비스의 적용이 필요하다. 본 논문에서는 국내외 전력부가서비스 시스템의 비교 분석을 통해 국내 전력산업 환경에 적합한 새로운 전력 부가서비스 적용방향을 제시하고, 이를 기초로 설계한 전력부가서비스의 일종인 전력 에너지 컨설팅 서비스 시스템에 대해 소개하고자 한다. 설계한 전력부가서비스 시스템의 적용시 전력소비자 측면에서는 요금절감 효과가 전력회사 측면에서는 부하 수요관리 및 투자비 절감 효과가 예상된다.

The market trends of automatic meter reading associated with smart water meters were investigated. Also, recent developments and field applications of key technology for automatic meter reading associated with smart water meters were analyzed. Smart water meters have been manufactured mostly in United States and Europe and have been expanded their business to Asia. Integrated water management system combining with the additional functions such as real-time consumption metering, cost notification, water conservation, leak detection, water quality monitoring, and flow control have been operated in automatic meter reading. Both water quality and quantity data measured from smart water meters and sensors were transferred to data concentration units through neighborhood area network, and then were transferred to integrated server through wide area network. The data transfer methods were determined by comprehensively considering urban scale, density of smart water meters, power supply and network topologies. Common data collection methods such as fixed network to data concentation units, vehicles drive by, people walk by, and drone fly by have been applied. The automatic meter reading associated with smart water meters are spread throughout the world, and both water and energy savings result in saving the money and reducing the greenhouse gases emission.

Due to the advantages of a conveniet, inexpensive installation, flexibility, and scalability, Wireless AMR systems are recently preferred over wired AMR systems. However, a multi-hop supported AMR network, which generally covers large areas, may create energy wastage problem, energy unbalance, and high interference hazard due to a large amount of concurrent-intensive metering data in the network. Therefore in this paper we propose a novel data gathering method which can solve abovementioned problems as well as conserve energy, by reducing the traffic in the network. In addition, the experimental results demonstrate that the proposed scheme shows superior performance to the conventional data transmission method.

This paper is a study on development of a new structured AMR/AMI(automatic meter reading/advance metering infrastructure) system. The developed system has a faster reading and is cheaper and easier to install compared to the existing AMR/AMI system. The system can be applied to AMR/AMI for five kinds of meters, electricity, gas, water, hot-water and calorie meter, which are used in most Korean households. Test results show that the developed system is both economical and reliable both in theoretical and practical applications. The resuts also show that the developed system is more suitable than existing system for AMR/AMI applications.
