ZIGBEE based Wireless SCADA System

TL;DR: In this article , a Zigbee-based wireless S CADA system (ZBWS) is proposed for cost reduction in the industrial environment, which is ideal for industries where it is too expensive to install wired SCADA in remote locations.
Abstract: The advancement of the remote monitoring industry has become more level-playing in recent years. This means that companies can now monitor their equipment remotely, without having to be present onsite. With the introduction of wireless S CADA systems, these systems became more affordable and efficient. SCADA systems have advanced significantly in the field of process control in recent years. SCADA is a supervisory control that is very important in the automation industry. Today, SCADA is required to control the process from any distance. Additionally, the potential for additional features such as security, process parameter control, and visualization paves the way for SCADA to become a powerful tool for industrial applications. Using SCADA, the entire process area can be monitored remotely. Automatic process manipulation, warning system, and automatic report generation are huge advantages of SCADA. Wireless SCADA is ideal for industries where it is too expensive to install wired SCADA systems in remote locations. Fortunately, wireless SCADA systems offer all the benefits of wired systems without the expense and hassle of wiring everything. In this study, an innovative prototype of a Zigbee-based wireless S CADA system (ZBWS) is proposed for cost reduction.

TL;DR: The proposed cyber-physical smart light control system (CPSLCS) testbed is integrated to the existing HIL CPS SCADA testbed to demonstrate the efficacy of the proposed algorithm by real-time performance and latency between the SLCC and SLAs.
Abstract: This paper presents a hardware-in-the-loop cyber-physical system architecture design to monitor and control smart lights connected to the active distribution grid. The architecture uses Zigbee-based (IEEE 802.15.4) wireless sensor networks and publish-subscribe architecture to exchange monitoring and control signals between smart-light actuators (SLAs) and a smart-light central controller (SLCC). Each SLA integrated into a smart light consists of a Zigbee-based endpoint module to send and receive signals to and from the SLCC. The SLCC consists of a Zigbee-based coordinator module, which further exchanges the monitoring and control signals with the active distribution management system over the TCP/IP communication network. The monitoring signals from the SLAs include light status, brightness level, voltage, current, and power data, whereas, the control signals to the SLAs include light intensity, turn ON, turn OFF, standby, and default settings. We have used our existing hardware-in-the-loop (HIL) cyber-physical system (CPS) security SCADA testbed to process signals received from the SLCC and respond suitable control signals based on the smart light schedule requirements, system operation, and active distribution grid dynamic characteristics. We have integrated the proposed cyber-physical smart light control system (CPSLCS) testbed to our existing HIL CPS SCADA testbed. We use the integrated testbed to demonstrate the efficacy of the proposed algorithm by real-time performance and latency between the SLCC and SLAs. The experiments demonstrated significant results by 100% realtime performance and low latency while exchanging data between the SLCC and SLAs.

TL;DR: Having possibility of additional features like security, visualization, controlling of process parameters paves the way for SCADA being a powerful tool for industrial applications.
Abstract: In recent years the SCADA system made a huge development in the field of Process Control. SCADA is a Supervisory Control that plays a tremendous role in the field of Automation. A control of process from any remote location is not happening without SCADA nowadays. Also, having possibility of additional features like security, visualization, controlling of process parameters paves the way for SCADA being a powerful tool for industrial applications. A complete process field can be brought into visualization in the remote using SCADA. The automatic handling of the process, warning system, auto report generation is the tremendous advantages of SCADA.

TL;DR: A Supervisory Control and Data Acquisition System (SCADA) based on wireless communication mechanism combined with General Packet Radio System (GPRS) platform and wireless sensor networks (WSN) can be efficiently used for on-site supervision and control of remote equipments in harsh environment.
Abstract: The paper presents a Supervisory Control and Data Acquisition System (SCADA) based on wireless communication mechanism combined with General Packet Radio System (GPRS) platform and wireless sensor networks (WSN). In order to access the services rendered by the WSNs and to extend its communication capabilities, a WSN controller was implemented with Xilinx spartan-3E, XC3S250E-4FT256C for the demand of relaying various types of monitoring and control data over a large-scale communication. In the WSN monitoring system network, a protocol stack dispatcher, known as Operating System Abstraction Layer (OSAL) over TI's ZStack protocol stack, was chosen to fulfill the strict requirement for the performance of real-time data acquisition and control, as well as the stability of operation system. Some key strategies of the supervisory of task polling were employed to make the management of the WSN controller more robust and flexible. The developed system can be efficiently used for on-site supervision and control of remote equipments in harsh environment.

TL;DR: In this paper , the authors designed a Wi-Fi setup with a backup power source of 4-5 hrs. so that even in outage of main power supply the WiFi will provide a no interrupting network and also range has been extended of about 18 meters more in Wi -Fi dead zones.
Abstract: Wi-Fi allows users to connect to the internet without the use of wires. It also allows routers to be cordless, which makes things much easier until they run out of power (power outage) or there's nowhere to plug in. When the power goes out, the internet connection via Wi-Fi is disrupted. As we go further away from the router; the Wi-Fi signal becomes weaker. We most likely come across Wi-Fi dead zones on a frequent basis. When encountering diverse router ranges, using connected multiple routers and manually connecting them. The work is designed a Wi-Fi setup with a backup power source of 4-5 hrs. so that even in outage of main power supply the Wi-Fi will provide a no interrupting network and also range has been extended of about 18 meters more in Wi-Fi dead zones.

Abstract: Today’s Supervisory Control and Data Acquisition (SCADA) networks manage power grids, water and sewer systems, automated factories, and many other complex systems. As these systems have evolved, so have the security challenges they face. We describe our research in strengthening SCADA security through development of a test bed for experimentation, formal system modeling, efficient implementation of security protocols, and consideration of human factors impacting system security.
