Description

Technical Field

[0001] The utility model belongs to the technical field of remote control of hydropower station gates and relates to an emergency control device for hydropower station gates based on an on-site data acquisition control server. Background Art

[0002] The water gates such as the spillway gate, flood discharge tunnel gate, and emptying tunnel gate on the dam side of the hydropower station are generally far away from the control room on the power station side. During special periods such as when the flood peak is approaching or the dam is under maintenance and the gates must be opened to release water, the opening and closing of the gates often requires special staff to go to the site to operate the local control unit. With the development of communication technology, some hydropower stations have achieved remote monitoring from the control room on the power station side to the gates by laying optical fibers, which facilitates the supervision and operation and maintenance of the gates on the dam side by the power station staff and improves the centralized control capabilities of the entire station.

[0003] Although fiber optic communication can meet the long-distance transmission requirements of gate status signals and control signals, this communication method is greatly affected by geological disasters around the site. When major natural disasters such as earthquakes, mudslides, and landslides occur, buried optical cables are often damaged, resulting in communication failures. In addition, it is difficult to locate and repair the fault point after the long-distance optical cable is damaged. In order to ensure the reliable transmission of gate status signals and control signals in emergency situations, and to avoid the interruption of the optical fiber network when a major natural disaster occurs and the inability of emergency personnel to rush to the gate site in the first time, resulting in the loss of control of the dam gate, endangering the production and life safety of the reservoir and downstream residents, another set of safe and reliable wireless communication links should be deployed between the gate on-site control unit and the power station side control room as a backup.

[0004] Patent number 202122417917X is a GSM-based dam gate emergency control system, which proposes a dam gate remote control method based on the GSM communication network. As a 2G cellular mobile communication technology, GSM requires reliable communication between ground base stations for remote communication. However, most hydropower station dams are located in remote mountainous areas, and base station communications are easily blocked by mountains, resulting in low communication reliability. In addition, when major natural disasters occur, ground base stations are easily destroyed, resulting in communication interruptions. In addition, GSM is a public network with poor communication security. Utility Model Content
