Description

Technical Field

[0001] The utility model belongs to the field of remote control of hydropower station gates and relates to a hydropower station gate emergency control device based on remote IO. 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 optical fiber 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 station site. 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 and the inability of emergency personnel to reach the gate site in the first time when a major natural disaster occurs, resulting in the dam gate being out of control and endangering the production and life safety of the reservoir and downstream residents, a safe and reliable wireless communication link should be added between the gate on-site control unit and the power station side control room as a backup.

[0004] In addition, the general method based on wireless communication, server and Ethernet to build the hydropower station gate emergency control device requires changing the secondary security of the original computer monitoring system of the hydropower station, adding isolation devices and data gateways, and the communication transformation is difficult. Therefore, the hydropower station gate emergency control device can be built by combining wireless communication, remote IO and hard wiring to avoid changing the secondary security.
