This application relates to the field of automatic control technology, and provides a control method and apparatus for a pile driver used in wharf construction. The method includes: acquiring first position information of the pile head of the pile driver, and acquiring real-time depth position information of the pile point at the wharf; determining first movement distance information of the pile head based on the first position information and the real-time depth position information; acquiring soil information of the pile point; determining control parameter information of the pile driver based on the soil information, pile driving time information, and the first movement distance information; and controlling the pile driver to perform pile driving based on the control parameter information. By implementing the method provided in this application, precise control of the pile driver can be achieved, which is beneficial to improving the efficiency of the pile driving process.

The invention belongs to the technical field of electric power systems, and particularly relates to a quick-closing valve control method for transient stability of an electric power system based on deep reinforcement learning. Comprising the following steps: establishing a Markov decision model based on power system transient stability emergency control; constructing a quick-closing valve decision framework based on a near-end strategy optimization algorithm; constructing a deep reinforcement learning model for emergency quick-closing valve control; by introducing the deep reinforcement learning method, a more accurate and efficient quick-closing valve control strategy can be formulated, so that when the power system breaks down, the stability of the system is recovered more quickly, and the loss caused by instability is reduced.

The present application relates to a kind of lime-soil compaction pile construction system for collapsible loess area, before construction, good technology, material, equipment and site preparation, such as familiar drawing, prepare soil and lime, debug hole and ramming equipment, level site and surveying and setting out etc..During construction, first carry out test pile to determine parameters, large-scale hole formation follows specific sequence and strictly controls pile diameter, perpendicularity etc.;Pile formation first clean bottom ram, then layered packing ramming, accurate operation by control system;After pile formation, do well maintenance.Quality detection uses low-strain dynamic penetration method to detect pile integrity, plate load test to detect composite foundation bearing capacity.The method is applied to a certain commercial complex project, construction is smooth, hole formation and pile formation quality meet the standards, efficiency is improved, construction period is shortened.
