[0002] In water conservancy projects, as an important hydraulic structure of a hydropower station, a dam is crucial to the safety of life and property of people downstream and the economic benefits of the hydropower station. Therefore, more and more attention is paid to the safety monitoring of the dam, and the dam safety monitoring has gradually started since the construction period. In order to improve the technical skill level of the hydropower station dam safety operation personnel, dam safety monitoring skill training and competition need to be carried out regularly. However, when training and competition are carried out by using the dam safety monitoring automation system of the hydropower station, there is a problem of affecting or even damaging the dam safety monitoring of the hydropower station. In addition, the dam of the hydropower station is far away from the living camp, and it is not convenient to carry out training and competition at any time; and after the dam is built, a large number of internal monitoring instruments of the dam (such as thermometers, strain gauges, joint meters, multi-point displacement meters, reinforcement meters, earth pressure gauges, etc.) are buried in the dam body, so that the structure, principle and running state of the internal monitoring instruments of the dam cannot be directly mastered, and the hydropower station dam safety operation personnel cannot contact the internal monitoring instruments. Therefore, it is urgent to design and research a hydropower station dam safety monitoring simulation system to solve the above technical problems. SUMMARY

[0012] A changing step: after the physical quantity of the monitoring instrument in the deformation monitoring simulation area, the seepage monitoring simulation area, and the internal monitoring instrument monitoring simulation area is changed, the measurement step is returned to be executed again;

[0013] The measurement step and the changing step are executed multiple times, the simulation monitoring data are analyzed based on a monitoring instrument calculation formula, an alarm is simulated based on an analysis result, a simulation scene is managed, and a manual interaction interface is provided for training and testing.
