Want to know the running status of on-site equipment remotely? This requires certain Internet of Things technology to monitor, measure and collect on-site sensors and equipment, and to monitor and control on-site signals and equipment. To achieve this goal, RTU plays an important role.
What exactly is RTU?
Among production process automation devices, PLC and DCS are the most widely used control systems. However, with the development of industrial automation, modularization and miniaturization have become new development needs. More and more users want to replace small-scale control systems with a terminal module. The PLC system implements data collection, and at this time RTU (Remote Terminal Unit) appears.
RTU has a wide range of applications, especially in fields such as hydrology and water resources, pumping station water intake, water supply systems, municipal pipe networks, environmental online monitoring, wide-area monitoring, etc. Since the work site needs to be monitored and controlled in an open-air environment, There is a huge demand for long-distance on-site monitoring, which has given rise to the rapid development of RTU.
Through its own software (or intelligent software) system, RTU can easily realize the telemetry, remote control, remote signaling and remote adjustment functions of the central monitoring and dispatching system for on-site primary instruments. It plays an irreplaceable role in data collection and processing of field equipment, on-site control, data transmission (network communication), on-site and remote alarms, etc.
With the rapid development of big data, cloud computing and the Internet of Things, this requires RTU and the entire SCADA system to be more open and easy to integrate, and more data interfaces can be connected to the system.
Therefore, RTU needs to evolve and evolve to keep up with the development of the times. According to the needs of the new era, it is given new elements and functions to extend the application scope of its automation control products.
With future development, the times will also give RTU new responsibilities, add more new elements and functions, and unleash its huge potential in more fields. Zongheng Intelligent Control will continue to carry out technological innovation and research and development, keep pace with the times, and produce RTUs that meet the requirements of the new era!
