Technical Field

[0001] This invention relates to the field of remote terminal communication, and in particular to a method for cascading and communicating remote terminal devices. Background Technology

[0002] Remote terminal units (RTUs) are an important type of equipment in power systems, used for monitoring, controlling, and protecting power equipment. A TTU typically has multiple terminal units, enabling it to communicate simultaneously with multiple power devices and exchange data and transmit commands with the remote master station.

[0003] Existing remote terminal units (RTUs) are typically independent devices that cannot be directly interconnected or work collaboratively. Due to the lack of effective cascading and communication methods, these RTUs cannot achieve unified control, data sharing, and task coordination, limiting their flexibility and efficiency in practical applications.

[0004] Currently, several technologies have attempted to cascade and communicate remote terminal devices, such as Bluetooth, Wi-Fi, and wired connections. However, these methods have several drawbacks, including limited communication distance, slow data transmission rates, and dependence on network connections between devices. Therefore, there is an urgent need to provide a new method for cascading and communicating remote terminal devices to overcome the shortcomings of existing technologies. Summary of the Invention

[0035] System initialization: Perform system initialization operations on each remote terminal unit in the cascaded network.

[0036] Network Planning and Configuration: Based on scenario requirements, optimize the distribution and network topology of remote terminal units (RTUs). Optimizing the distribution and network topology of RTUs improves system reliability. A reasonable distribution and network topology allows RTUs to be distributed across different locations, achieving redundancy and backup to reduce the risk of single points of failure. If a region or node fails, other regions or nodes can continue to operate, ensuring system reliability. It also enhances system flexibility and scalability. A reasonable distribution allows for flexible adjustment of system size and capacity, expanding or shrinking according to actual needs. A good network topology easily supports the access of new nodes or devices and enables dynamic management and configuration of the system. Furthermore, it improves system performance and response speed. Optimizing the network topology shortens data transmission paths and reduces latency, improving system performance and response speed. Especially for applications requiring real-time response, such as industrial control and intelligent transportation systems, an efficient network topology ensures that real-time performance is met. Finally, it reduces system cost and energy consumption: a reasonable distribution and network topology reduces the amount of cabling and equipment used, lowering system construction and maintenance costs. Furthermore, reducing data transmission distance and energy consumption can lower system energy consumption levels and improve energy efficiency. It can also enhance system security: a well-structured network topology allows for network segmentation and policy control, improving system security. Properly distributing terminal devices can also reduce the risk of single-point attacks and utilize distributed security strategies to protect system security.
