The Intelligent SCADA Technology Research Team (IST) is under the Intelligent Systems Research Group (INSRG). Nowadays, advanced and complex remote data acquisition and control technologies play important role in remote monitoring systems of the industry, utilities, and the government sectors . Additionally, the Open Charge Point Protocol (OCPP), Open Charge Point Interface (OCPI), and Energy Management System (EMS) are currently operational on the customer’s system (Elex by EGAT). The majority of these technologies are imported from abroad. IST was established to focus on research, design and development of technologies related to SCADA systems, aiming at inventing and applying our technologies to Thai industry as well as neighbouring countries.

Vision 

Focus on research and development of remote monitoring and measurement systems for viable applications, as well as research on EV chargers, according to Thailand’s sustainable development plan.

Mission 

Aim to research and develop high efficiency and flexibility of remote monitoring and measurement system , as well as research on EV chargers, to enhance domestic industrial satisfaction and to keep researchers in touch with frontier innovations.

Core Technology

IST specializes in the research and development of mechanical and electrical measurement system by using Remote Terminal Unit (RTU) under tropical environment including energy saving ability and high reliability. Moreover, we are also familiar with user-friendly back-end system such as multi-propose database, user-friendly interface, decision support system and interfacing with existing system by using standard protocol.

Key Achievements / Commercialized Projects

1. Dam Safety Remote Monitoring System (DS-RMS)

The Dam Safety Remote Monitoring System (DS-RMS) is an advanced monitoring system collaboratively developed by the Electricity Generating Authority of Thailand (EGAT) and the National Electronics and Computer Technology Center (NECTEC), specifically by the Remote Sensing and Control System Research Team (IST). This initiative integrates information and communication technology with dam behavior monitoring instruments to enhance confidence in the safety and security of EGAT’s major dams.

DS-RMS has been designed to automatically communicate data from various monitoring instruments including dam behavior sensors, seismic activity monitors, and flood measurement tools installed within dams and around reservoirs. This data is transmitted to a central computer system for processing and analysis using an expert system that can predict potential causes of anomalies. The system provides real-time dam safety status updates through a web-based application, displaying critical information via a dedicated website interface. Additionally, in case of detected irregularities, the system issues automated alerts via SMS and email to relevant personnel, ensuring timely inspections and corrective actions. Furthermore, EGAT executives are promptly informed to facilitate transparent communication with the public.

The information technology and visualization components of DS-RMS were jointly developed by EGAT and NECTEC, with advisory support from the Geotechnical and Foundation Engineering Research Center, Faculty of Engineering, Kasetsart University. These collaborations helped establish safety alert criteria and develop the expert system, incorporating recommendations from leading Thai dam engineering specialists.

The development of DS-RMS spanned 3 years (2014–2016) and has now been fully implemented. Currently, the system is operational in 14 major EGAT dams, namely: Bhumibol Dam, Sirikit Dam, Srinagarind Dam, Vajiralongkorn Dam, Ubol Ratana Dam, Sirindhorn Dam Chulabhorn Dam, Huai Kum Dam, Nam Pung Dam, Pak Mun Dam, Lamtakong Jolabha Vadhana Power Plant, Rajjaprabha Dam and Bang Lang Dam.

Additionally, as part of the DS-RMS project, the research team has developed a Remote Terminal Unit (DAM-RTU) specifically designed to measure water pressure levels at various monitoring stations within dams, meeting EGAT’s operational requirements.

2. The Thailand EV Roaming Platform System (TER)

Thailand EV Roaming Platform System (TER) is a network integration platform for managing the EV charging stations. It supports both the Open Charge Point Protocol (OCPP) and Open Charge Point Interface (OCPI), enabling seamless connectivity between platforms. By utilizing both standardized and customized APIs, the TER system can simplify integration, accelerates system consolidation, and facilitates cross-network payments without hassle. It also provides real-time and accurate status updates on charging stations across the third-party network while maintaining high-security protocols, such as Security Credential Tokens, TLS, and Network Security. Additionally, the system is designed to support the expansion of EV infrastructure efficiently. For over 2 years, the TER system has been tested with Charge Point Operator (CPO) servers, mobile application back-end servers, and Open Charge Point Protocol (OCPP) servers. This ensures that Elex by EGAT enables members to access services from other charging service providers through OCPI, without any additional complexity for EV users.

Cyber-Physical System or CPS is engineering system that seamlessly integrates physical world with cyber world. Physical world includes all kinds of physical objects such as devices, machines, systems (man-made or natural), environments, and even humans ourselves. Cyber or digital world provides computation and control. Combining the two worlds requires, first and foremost, connectivity among physical things such that they can interact as a network a.k.a. Internet of Things (IoT). IoT also acts as a bridge between the physical and cyber sides of a cyber-physical system. Through sensors, live data can be retrieved from a physical system and processed in the cyber space in order to produce decision, which is then passed back via actuators to control the physical system in continuous, autonomous loops.

CPS is therefore far more comprehensive than IoT as it involves not only connectivity, but also computation and control. It is the scaffold, upon which all the ‘smart’ technologies are built. However, design and implementation of a cyber-physical system are complicated, considering they take interdisciplinary knowledge including computer science, mathematics, electrical engineering (electronics, computer, and control), mechanical engineering, industrial engineering, manufacturing engineering, etc.

For Thailand 4.0 initiative, NECTEC, NSTDA is set to promote CPS as one of its leading technologies going forward. Center for Cyber Physical Systems has been formed from NECTECs three core areas of research expertise: sensors, network/system, and artificial intelligence/data analytics with a mission to facilitate implementation of CPS technology in various economic sectors such as industry, agriculture, and urban infrastructure.

]]> Smart Machine and Mixed Reality (SMR) https://www.nectec.or.th/en/research/iiarg/smr.html Thu, 16 Jun 2022 02:00:19 +0000 https://www.nectec.or.th/en/?p=21722

The Smart Machine and Mixed Reality (SMR) Research Team conducts research in the field of advanced robotics and automation technology. In the near future, with advancements in Artificial Intelligence (AI) and microprocessor technology, smart machines or robots are expected to become smarter and capable of performing more complex tasks than ever before. Additionally, the demand for smart robots is increasing due to Thailand’s aging population. However, there are still some limitations that prevent robots from fully realizing their potential. These areas require further research and studies to overcome. Therefore, SMR focuses on research and development in AI and related fields of robotics.

In the past, SMR collaborated with the Electricity Generating Authority of Thailand (EGAT) on the Generator Inspection Vehicle (GIV) project. The GIV is a mobile robot designed to navigate between the narrow gap between a generator’s rotor and stator. The initial version of the GIV has been utilized by EGAT for maintenance services of power generators since 2015 and continues to be employed to this day.

In addition, SMR is currently engaged in projects related to smart factories, including the development of mobile robots and inspection robots. These robots will be increasingly necessary in Thailand’s industrial sector as the country transitions to the Industry 4.0 era. Another emerging technology trend that SMR is also interested in is Digital Engineering. Digital Engineering encompasses Virtual Reality (VR) and Augmented Reality (AR), which serve as bridges between the virtual and real worlds. These technologies enable users to visualize and comprehend intricate tasks and provide enhanced experiences in interacting with information in the cyber realm, thereby improving work efficiency.
