With the continuous advancement of astronomical observation technology, the design of modern telescopes is increasingly  inclined towards high precision, high automation, and intelligence. As one of the core components to achieve these goals,  control bus technology plays a crucial role. This paper provides an overview of the relevant technologies of telescope  control buses, focusing on their system architecture, common communication protocols, and application scenarios. The  basic architecture of telescope control buses is analyzed, including the selection of communication buses, hardware  interfaces, and data flow management. Furthermore, commonly used communication protocols in current telescope  systems, such as VME bus, EtherCAT bus, CAN bus, Fiber Channel bus and Macro bus, are introduced. Their advantages  and disadvantages in terms of real-time performance, reliability, and bandwidth are evaluated. Finally, the practical  applications of telescope control buses in areas such as pointing control, tracking accuracy, and system integration are  discussed. This paper summarizes bus control technology development trends and provides insights into the innovation  and challenges of future telescope control bus technology.
