Embodiments of the present application provide a head cap and a brain electrical near-infrared synchronous acquisition device. The head cap comprises a main body, a plurality of pads, a plurality of probe mounting portions and a plurality of electrode mounting portions. The main body is used to form a space for accommodating a head of a subject. The plurality of pads are arranged at different positions on the inner side of a first part of the main body, so that each pad forms a laminated structure with the first part of the main body. The plurality of probe mounting portions are arranged on the laminated structure and are used to mount probes for acquiring fNIRS signals. The plurality of electrode mounting portions are arranged on a second part of the main body which is not provided with the plurality of pads, and are used to mount electrodes for acquiring electroencephalogram signals. In this way, the pads can position the probe mounting portions and maintain the spacing between the probe mounting portions, thereby improving the performance of near-infrared brain function imaging. Meanwhile, the electrodes for electroencephalogram and the probes for near-infrared brain function imaging do not interfere with each other, are reasonably arranged, and achieve the best data acquisition effect.

This invention discloses a method and system for monitoring and maintaining tower operations, belonging to the field of tower operation and maintenance monitoring. The method includes the following steps: S1: basic monitoring data acquisition; S2: edge-side data cleaning and initial screening; S3: global data spatiotemporal standardization; S4: cross-modal feature fusion and defect identification; S5: result integration and application. By constructing a multimodal perception network including a lidar sensor, a high-definition industrial camera, and an inertial measurement unit, the sensor deployment location and time-triggered synchronization protocol are clearly defined, and geometric, texture, attitude, and environmental data are collected synchronously to achieve comprehensive multi-dimensional data coverage. Through global data spatiotemporal standardization processing, a global coordinate system is established with the tower bottom as the origin. By retrieving historical operation and maintenance archives from the cloud, operation and maintenance strategies are generated based on a similarity threshold, and the current monitoring data, identification results, and strategies are written back to the historical archives to update the tower health status database.

This invention discloses a dual-head machine tool for semiconductor material processing, belonging to the technical field of semiconductor material processing equipment. It includes a frame with a cleaning mechanism, comprising: a liquid washing device mounted on the frame; an air washing device mounted on the frame, with the air washing device and liquid washing device arranged opposite each other; and a fixing device mounted on the frame, comprising a first fixing component and a rotating component. The first fixing component can fix one end of a workpiece removed from the clamping mechanism, with the fixed end of the workpiece located on one side of the air washing device, and the portion of the workpiece not clamped by the first fixing component located on the one side of the liquid washing device. When the first fixing component fixes one end of the workpiece, the rotating component can rotate the portion of the workpiece not clamped by the first fixing component to the side of the air washing device. This invention improves upon the problem of incomplete cleaning of the semiconductor material processing surface during semiconductor material processing using dual-head machine tools in the prior art, thereby improving the quality of the finished product.
