Korea 2 Research & Development Team, Hydrology Engineering & Consulting Center, S. Korea Inc. track0614@naver.com Abstract Recent shifts in the water resource management paradigm and information and communication technologies (ICT) call for platform-based integrated operation management technology, which provides the multidimensional approach of two-way communication. To domestically prepare for such paradigm changes, research on the Smart Water Grid, which is intelligent water management that combines water resource management with ICT, remains ongoing. In this paper, we propose a framework for using the components of a variety of program modules to build an intelligent watermanagement-integrated operation system that is appropriate for the Smart Water Grid. In addition, we suggest a system development environment and integrated operation system implementation plan for using the Core-Platform framework Keywords: Smart Water Grid, integrated management system, core-platform, ICT 1. Introduction The existing water resource management system is unreliable on account of a lack of real-time data. Moreover, the weakness of the information and communication technology (ICT) integrated system and program development is evident in the lack of a water disaster warning system and in the water resource-related data infrastructure. Furthermore, the lack of standardization between the water resource ICT management system and system development has led various companies developing such, making program integration and data integration difficult, and limiting water management system efforts toward effectiveness. To address these problems, in terms of water resources, the smart water grid places critical importance on building the next-generation water resource system and infrastructure by using multiple water sources to overcome existing water resource management system limitations. The smart water grid further emphasizes the need for the stable supply and information management of water through technological innovation and intelligence by combining water resource management and ICT to address the continually increasing demand for water in the context of rapid changes to the water resource environment and rapidly changing global water industry [1]. Additionally, recent changes to the water management paradigm and ICT have resulted in more effective and intelligent water management using two-way communication. To this end, water companies in advanced economies are calling for solutions using a multidimensional approach and methods to address the water shortage and management through the use of stable water resource acquisition and communication, maintenance, and modeling technologies to address the water shortage and management[2]. In particular, standardization of system development technology and water data is needed to increase effectiveness of the use of ICT through the creation of a single large system. A system of systems, this single system would include the various component ISSN: 1738-9984 IJSEIA Copyright c 2015 SERSC
technologies and have effective integrated operations and management as standardized technologies. Domestic technologies related to an ICT-based integrated operations system fall behind that of advanced technologies on account of limited actual application or experience with component technologies. However, software development skills of other areas are comparable or have only minor differences when compared to advanced technologies. The gaps exist because of the lack of standardization and management of a water-related integrated platform. Therefore, responding to the gaps is critical to advanced integrated management technology and water data as well as to the effective utilization of water resources. Accordingly, the integrated operation system used for the smart water grid cannot be a one-time development; rather, it must be sustainably in operation by allowing for easy maintenance for continuous inspection and optimization. Furthermore, for commercialization and to keep up with global trends, the system must be developed as a single platform that allows for managing a variety of programs [1]. Therefore, in this paper, we propose the creation of a single framework that combines a variety of program module components that were developed to comprise an intelligent water management integrated operation system that is appropriate for a smart water grid. In addition, we propose a system development environment and implementation plan for using this framework, such as the Core-Platform. The remainder of this paper is organized as follows. In Section 2, we discuss relevant research. In Section 3, we describe the concept of the integrated operation system and development method. We propose a scenario for realizing the integrated operation system and describe an implementation plan in Section 4. Our conclusions and future challenges are discussed in Section 5. 2. Relevant Research 2.1. Integrated Operation System The integrated real-time water management system (IRWMS) is a real-time water management decision-making support system that is aligned to South Korea s water resource operation environment by introducing integrated water resource management to river basins. To build the water resource system, an appropriate model has been selected for the integrated basin. In addition, an integration plan for the irrigation, depth, and water management models, a system configuration reflecting the relevant basin s characteristics, and a graphical user interface (GUI) that is convenient for each model s data input, output, management, and use have been developed and applied [3]. Presently, facility-specific safety management systems based on sensor networks are rapidly being developed. However, the lack of standardization has resulted in the development of a diversity of systems. To manage these diverse sensor network-based safety management systems in an effective and integrated manner, development of an integrated operation system and an information-sharing system, which enables the optimal real-time integrated operation system and early warning system for reliability and scalability, as well as related systems and interlocking protocol standardization, has been underway[4]. The integrated operation system addressed in this study can be applied to the smart water grid and is an intelligent integrated operation system. It cross-monitors the data and software of various programs for effective water resource management. 2.2. Core-Platform A platform refers to the system architecture that serves as the foundation for running applications through lower-level operations, such as a connecting processor with an interface, determining the file system structure, and allocating and distributing resources [5]. A software platform can be described as the foundational software that includes the 56 Copyright c 2015 SERSC
operating system, middleware, and development tools, which exist in the space between the hardware and application programs. POSIX, the representative platform of an embedded system, standardizes the system call. The standard for the software platform, which includes the middleware and API, provides the core functions commonly used for system call expansion and shrinkage for the applications. The software platform is already being utilized in the u-city as the software infrastructure that provides the core information technology (IT) service as the city s information service platform. It differentiates the u-city with its integration of information and construction from the concept of the conventional city. Such middleware is being newly defined by its various application areas by the relevant industries [6]. Core-Platform can be described as the software platform for the construction of a water management system and infrastructure that can employ and manage water resources in an effective manner and can be perceived as the foundation for an intelligent integrated operation system. 3. Configuration and Development Method of the Smart Water Grid Monitoring System 3.1. Configuration of the Monitoring System The smart water grid monitoring system for intelligent water management package construction is depicted in Figure 1. With Core-Platform as the basis, it provides the database foundation for the seven programs to be integrated or interlinked water treatment combination, water loop operation, select water intake, business support, water shortage assessment, available water quantity calculation, and AMI network programs. It furthermore provides a representative component for seamless linkage with an SWGintegrated database by enabling database usage or defining the interface standards [7]. All programs configured with such a package are capable of integrated management of each program s real-time monitoring and alerts of its operation status, server status, and user status. Figure 1. System Configuration Copyright c 2015 SERSC 57
3.2. Monitoring System Development Method Figure 2. Core-Platform Configuration For the purposes of packaging, within the server-client (C/S) architecture, each program developed for the smart water grid is configured to be the client, while the database functions as the server. These programs are developed with the C# objectoriented language. Furthermore, the programs developed for the smart water grid are developed with the framework-included platform as its basis, as shown in Figure 2. Because the platform and frameworks are configured as library and components, they use the component-based development (CBD) method of the MARMI III methodology. MARMI III is a methodology that was developed to fit project processes that are capable of realizing component-based object-oriented technology, minimizing the system s maintenance costs, and realizing a high-quality information system. It is a methodology with which applications are developed at a component level and are then assembled. It is suitable for the current program s development purposes by supporting component-level development, assembly, and maintenance. The developed Core-Platform is configured with a collaborative class-providing modeling framework as its basis. Its configuration and implementation enables the software s specific parts to be reused, and it improves the software s service, performance, credibility, and compatibility through functions, such as modularization, reusability, and expandability. Furthermore, it eliminates each program s redundancies by applying a software technique that operates and manages them in an integrated manner and uses the developed framework with an integrated library, which each program commonly utilizes. The component used by each of the programs and the integrated operation system were developed as the Core-Platform and installed as shown in Figure 3. The components used in the Core-Platform were developed as listed in Table 1. GIS was developed using Open Source to allow for use of Map and Layer, and the database was developed using Oracle 10g to enable data and database management by providing the WaterML component. Communication is primarily used by AMI network management. In addition, components capable of network management, such as TCP and WCDMA, and of protocol management, such as Modbus and the SWG Protocol, were developed. It was furthermore developed to include encryption and decoding components for security, while enabling program and process management as the management component. Furthermore, a user interface was developed with the tool-type time series, spread sheet, chart, and graph components so that all programs can use them. 58 Copyright c 2015 SERSC

Monitoring System Development and Integrated Operations 4.1. Monitoring System Integrated Operation Scenario Common Components For all programs developed with the Core-Platform foundation to operate as a single program in the smart water grid, all input and output data of each program was crossreferenced. In addition, the data was used to develop a monitoring system, shown in Figure 3, for effective water management. Data production and storage within the smart water grid starts with multiple water source level estimation to be built into the integrated data. Real-time measurements of the multiple water source and real-time water consumption rates are calculated and stored as data, which is re-calculated using the water shortage threat assessment program and then stored. The reserve level of the multiple water sources is then calculated to determine the current water supply of the multiple water sources. This allows for an optimal water intake level for combined water treatment. The scenario was developed such that water treated through the combined treatment process is distributed and supplied through a water loop. Figure 3. Implementation Scenario Copyright c 2015 SERSC 59
4.2. Intelligent Monitoring System Development The smart water grid integrated operation system was developed according to the method described in Section 2.2. The proposed implementation scenario is described in Section 3.1. Figure 4 shows the main login screen required for the monitoring system administer to enter the system s main page. Because the system administrator is a representative of a smart water grid-related public institution, the system representative provides a login and password using the new user registration function. This provides access to only authorized users. If a password is forgotten, the password find function can be used. Figure 4. Login of Program To operate each of the smart water grid programs as a single program, input and output data from multiple water source real-time measurement for water loop distribution and the water supply data are cross-referenced. To manage these data in an integrated manner, the monitoring system s main page was constructed to show the real-time monitoring and alerts of each program in the grid s package program, server, and user statuses (Figure 5). Figure 5. Normal of Operation Furthermore, the operation status of each program is based on the server database. This includes monitoring of the relevant database (DB) table and is evaluated for program errors based on hourly monitoring of the measurement data from the multiple water source and water reservoir with the program input and output data. In the case of a 60 Copyright c 2015 SERSC
program error, the error is indicated in the main page of the specific program that has the error, as shown in Figure 6. The incident is then communicated to operating personnel via SMS and E-mail. Figure 6. Abnormal of Operation Furthermore, if the hourly DB table monitoring detects data missing on account of a program error, communication sending/receiving not working, or data being unable to be transmitted because of a network disconnect, the program operator or integrated operation center situation room personnel can recover the data by rebooting the system. Figure 7. Error of Communication and Data Figure 7 is a sample page indicating the incident of a communication or data-related error. It shows the error on the relevant connecting line. In the case of such an error, the operating personnel are notified via SMS or E-mail. 5. Conclusion and Future Challenges In this paper, we proposed a scenario in which which programs with Core-Platform can be packaged to enable effective water management to achieve the development of an intelligent water management monitoring system that is applicable for a smart water grid. In addition, we proposed a system development environment and implementation plan. Copyright c 2015 SERSC 61
The monitoring system was developed by using a Core-Platform foundation for each program s library and components. It was configured for convenient system unit development, assembly, and maintenance. This system allows for the distribution of an effective water supply to regions by using real-time data measurements from multiple water sources, water loop distribution, and supply input and output data. The proposed scenario implemented the proposed system proposed. The integrated operation system developed through this study allows for each program s operation status, server status, and user status to be monitored and communicated via real-time alerts, while also enabling communicating program status or data/communication errors to be visualized on the operation screen and for the incidences to be communicated to operating personnel via SMS and/or e-mail. The integrated operation system was envisioned to be capable of integrating the operating and monitoring of each program and to enable the addressing of errors by operating personnel. After the system is applied in the field, further detailed research is required for optimal system establishment and stability by analyzing user requests from operating personnel and developers.
