In terms of water meter reading, the majority of 16 million houses use mechanical water meter in korea. So, a member of the utility's staff needs to access periodically the water meter and the value of the metered volume. However, due to the use of mechanical water meter, many issues have been appeared as cost, time, errors, accessibility, and readability. To settle these issues, we developed the walk-by meter reading system of digital water meter and outside indicator based on ubiquitous. And we could get the characteristics and the economical efficiency for water meter reading system. Thus, this study shows that the system can be widely used to the block system and the meter reading system for stable water supply.

The purpose of this study is to survey colors of background, marker, and pointer being used in passenger car's combination meter, and to suggest ergonomic design guidelines of combination meter to enhance driver's readability. An experiment was conducted, in which colors of background, marker, and pointer were selected as independent variables, and reading time, reading error, and preference for combination meter were measured as dependent variables. Most of passenger cars sold in Korea were found to have combination meter with black background, while marker. The experimental results showed that reading time of combination meter with white background, black marker and point was shortest, reading error was lowest in combination meter with black background, yellow marker pointer, and preference for combination meter with white background, black marker and black or red pointer was highest. The results implied that combination meter with white background, black marker and black pointer should be used for comprehensively optimizing reading time, reading error, and preference for it. It was expected that these results could be used as valuable design guidelines when designing combination meter of passenger car.

검침원이 방문을 통하여 계량기 지침을 읽고, 핸디 터미널을 이용하여 지침값을 입력하는 검침업무 시스템은 사생활 침해, 미검침 처리 및 오검침, 과다한 검침 비용 등의 문제가 발생하고 있다. 이런 고객서비스질의 저하를 막기 위하여 계량기의 지침을 자동으로 인식하고, RF 모듈를 이용하여 무선으로 검침데이터를 전송할 수 있는 원격검침 시스템을 설계하였다. 검침 데이터의 원시 자료 수집부터 수용가의 사용량 정보에 대한 통계정보 관리에 이르기까지의 전체적인 시스템을 설계함으로써 고객에게 보다 정확하고 구체적인 사용 정보를 제공하여 서비스의 만족도와 신뢰도를 향상 시킬 수 있으리라 사료된다.

계량기의 지침을 인식하고 수도 관리 사업소로 데이터를 전송하기 위한 검침모듈은 전원을 전력선으로 이용할 수 없다. 따라서, 검침모듈은 배터리를 이용해야 하므로 주기적으로 소모된 배터리를 교체하는 유지보수 문제가 발생한다. 유지보수 비용을 절감하기 위해 전원 소모를 줄이면서 무선으로 데이터를 전송 할 수 있는 방안이 필요하다. 본 논문에서는 효율적인 전원관리를 통하여 배터리 소모량을 줄이면서 고객계량기의 지침을 자동으로 인식하고, RF를 이용하여 검침 데이터를 전송 할 수 있는 원격검침 모듈을 설계하였다.

In this paper, we introduce automatic meter reading system for tap water. The system is composed of automatic meter, router using RF and CDMA network, and data server. This system will easily extend to fire detect, gas, and electric charge meter system. In addition, this system will be used to monitoring a water leak and human which live in solitude. Proposed system is installed at Gimhae-City and Gijang-gun. As a result of the automatic meter reading system for tap water, The leak of water and complain of user is decreased. But The building cost is still an obstacle to expand into entire city.

A communication protocol for automatic meter reading is designed for electronic power meter. Communicational functions and data structures are standardized and data reading software is developed according to the developed protocol. The communication protocol is designed with reference specifications, IEC 62056-31 and Distributed Network Protocol(DNP). For design, communicational functions and specifications of the industrial meters were analyzed for the purpose of developing a new one for KEPCO meters. The protocol is designed with 3 layer model, physical layers, data link layer and application layer. A documentation was completed with data gathering, data classification, authentication, error detection. An emulator system was made for testing the protocol. A meter reading software was developed using the protocol. Many different protocols and meter reading softwares are integrated into one with the developed protocol and software as KEPCO's standard.

This paper presents the AMR (Automatic Meter Reading) system using the binary CDMA (Code Division Multiple Access) radio technology. The binary CDMA is the new radio technology in domestic research. Main implementation topics includes the binary CDMA remote meter reading system, the wireless piconet configuration for the wireless automatic meter reading, and the transmission scheduling for sending and receiving data. Also, the wireless packet data encryption is very important topics for the wireless automatic meter reading. The proposed AMR system is implemented as a pilot project in Jeju and Gangwon. It can be seen that the wireless remote reading using the binary CDMA wireless technology can be applied to the AMR system.
