Inspection of an Electrical Meter is an action of measuring power usage to charge electricity rates and Electricity AMR(Automatic Meter Reading) is a system to automatize the action. AMR has been highlighted because it can reduce metering cost by substituting an automatic system for personnel and strengthen customer service. In this paper, we proposed and developed a smart card based AMR framework SCEMS as an alternative to other current AMR Models. This proposed SCEMS uses a java card based multi-application smart card and supports customer service such as various meter rates according to electricity consumption pattern data per household and transaction data that are accumulated in a smart card. This research can be a solution to the problems such as diversity, heterogeneity, and complexity that environmental changes will cause soon to the power supply industry.

According to the deregulations of governments in the world. the power industries of United State and European nations are proceeding remote meter reading and remote load control. But the core technology of multifunctional electronic meter implemented by programmable one-chip IC, which can be the right answer of all the power industy's efforts is now still under development in the advanced countries. Implementation of smallest size, lowest price single-phase meter with features which enable distribution automation such as bidirectional communication, Remote load control, remote meter reading, remote credit assigment. Prepayment billing system.

Recently, distribution load analysis using AMR (Automatic Meter Reading) data is researched in electric utilities. Load analysis method based on AMR system generates the typical load profile using load data of AMR customers, estimates the load profile of non-AMR customers, and analyzes the peak load and load profile of the distribution circuits and sectors per every 15 minutes/hour/day/week/month. Typical load profile is generated by the algorithm calculating the average amount of power consumption of each groups having similar load patterns. Traditional customer clustering mechanism uses only contract type code as a key. This mechanism has low accuracy because many customers having same contract code have different load patterns. In this research, We propose a customer clustring mechanism using k-means algorithm with contract type code and AMR data.

Recently, several papers for reading meters remotely using RFID/USN technologies have been presented. In the case of water meter, there has been neither commercial product nor paper. In this paper, we describe the design and implementation of wireless digital water meter with low power consumption. We use magnetic hole sensors to compute the amount of water consumption. The meter of water consumption is transferred via ZigBee wireless protocol to a gateway. Low power consumption design is essential since a battery should last till the life time of water meter. We present that dual batteries haying 3V, 3000mAh, would last 8 years by analyzing the real power consumption of our water meter.

This research developed a remote communication system for automatic water meter reading and charge calculation from the field of a house or apartment complexes within the same district. Developed system was applied to perform measurements of the pulse-sensing technology, the minimum power consumption, temperature compensation, short-range wireless communications technology, the handset and wireless communication capabilities of the DB management embedded software to efficiently control. Through this reading-related tasks that are required in a temporal, material and human resources can be minimized.

More efforts are required to efficiently operate and manage measured data in AMR(Automatic Meter Reading) and manual meter reading that have not become com:[m yet. As customer complaints increase the most appropriate way of finding solutions is precise and reliable metering of data which should be able to maximize customer satisfactions. In this parer, we designed a data mining technique that recommended the reliability of measured data on manual meter reading and a mCRM(Mobile CRM) system that expanded CRM(Customer Relationship Management). We will propose a mCRM in which the system compares the patterns of customer's using data. W the measured data gathered is outside of a similarity measure(maximum and minimum), it enhances the reliability of measured data by managing this fact in mobile for each customers. We will proposed a system where the mCRM provides customers with reliability and efficiency when related enterprises cannot establish AMR because of the burden of extra costs.

In recent, there has been progressed in various ways of research and development about a ubiquitous telemetry reading, but several problems are arising the reliability of reading value, power supply and so on. These issues were solved by using the RF module and digital pulse meter with photocoupler. Realized by this study, a telemetry reading system, utilizing RF and CDMA telecommunication, and check in real time the state of water leakage by managing the distinct usage data. In addition, the users can check it in person, and it can minimize the public enmities. Further, as a part of the silver industry fur constantly growing senior population, it might be introduced as safety supervision system.

In this paper, geographic information system(GIS) for an intelligent power distribution network was implemented with location informations acquired from automatic meter reading system, where the location informations of power line communication(PLC) modems installed at customer side were collected at data concentration units(DCUs) of headend equipment via PLC and then were transmitted to front end processor server. By displaying the connection status of the power distribution network on GIS map, operation of advanced metering infrastructure(AMI) or management of power grid system could be performed intuitionally and in real time, because the configuration state of the power grid could be easily monitored. The feasibility of the proposed system was confirmed with the especially constructed laboratory-level test bed and the verification test of the system will be carried out for a real power distribution network.
