Description

Technical Field

[0001] This utility model relates to the field of hydropower station communication technology, specifically a Beidou communication terminal system for hydropower stations. Background Technology

[0002] Hydropower stations are typically located in rural areas, often in mountainous regions with long distances. Furthermore, the various actuators within these stations are often situated within the mountains, hindering signal transmission. Therefore, stable control of each actuator is of paramount importance. Traditional communication methods carry the risk of monitoring and control failure. For example, ecological generating units, spillway gates, and flood discharge gates are all located inside the mountains, far from the tunnel entrances outside. Current long-distance serial communication technologies suffer from low reliability, weak resistance to electromagnetic interference, and a high rate of damage from lightning strikes. Extensive research has been conducted to address these issues. Utility Model Content
