The invention relates to the technical field of operation control, in particular to a control method and a control system for under-machine operation of a gantry crane. The control method comprises the following steps: acquiring connection data of a master control power supply of a cab of the gantry crane; judging the main control power supply connection data of the cab of the gantry crane to generate main control power supply connection judgment data; local connection knob selection is carried out on a door machine lower operation box based on main control power supply connection discrimination data, first knob selection data of the door machine lower operation box is generated, a main control power supply switching-on instruction is generated, and actions of a hoisting mechanism and a walking mechanism are achieved through interactive generation of control instructions of the hoisting mechanism and the walking mechanism. And finally obtaining anchoring state data capable of being anchored. According to the invention, by improving the functions of automation, intelligent control, fault detection and self-recovery mechanism, precise position matching and multi-position multi-mechanism operation, the convenience degree of operation control of the gantry crane in emergency is improved.

The present invention discloses a complex signal field recovery system based on native optical carrier, including a transmitting end digital signal processing module, a digital-to-analog converter, an electro-optical modulator, an optical fiber link, an optical coupler, a dispersion element, a photodetector, an analog-to-digital converter and a receiving end digital signal processing module; the transmitting end digital signal processing module performs nonlinear pre-compensation and DC bias correction of the electro-optical modulator; the electro-optical modulator converts the electrical signal from the digital-to-analog converter into an optical signal carrying target information, and generates a native optical carrier at the same time; the dispersion element performs dispersion on the optical signal passing through; and the receiving end digital signal processing module performs signal recovery operations. The present invention also discloses a complex signal field recovery method, including the following steps: electro-optically modulating an optical carrier signal using an electro-optical modulator with a finite extinction ratio; receiving an optical signal using a phase recovery receiver; and performing signal field recovery based on an improved Gerchberg‑Saxton algorithm in the receiving end digital signal processing module.

This invention relates to the field of geological exploration data processing technology, and discloses a method and system for AI fusion, identification, and analysis of multimodal geological data. The method aggregates and structures multimodal data such as physical fields, chemical elements, geological structures, and drilling core samples; constructs and iteratively optimizes a knowledge topology network based on geological semantics to express semantic relationships and spatial constraints between data entities; actively detects high-value information links and contradictions within the knowledge network; generates multiple parallel fusion decision-making plans accordingly, clarifying data coordination rules and feature enhancement directions; introduces external intervention commands to screen and reconstruct the plans, forming a target fusion operation sequence; executes the sequence and synchronously evolves the knowledge network. This method realizes a transformation from static data association to dynamic knowledge guidance, and from fixed algorithms to human-machine collaborative proactive decision-making, improving the reliability of geological target identification and the level of intelligent analysis.
