Abstract: In recent years, various natural disasters and emergencies have occurred frequently at home and abroad, and the demand for emergency rescue has gradually increased. Helicopters are widely used in emergency rescue due to their advantages such as fast rescue speed, high efficiency, and strong professionalism. However, the path planning in helicopter emergency rescue lacks mission-driven considerations, which can easily lead to insufficient helicopter emergency rescue efficiency, and often the impact of the mission environment will be ignored, resulting in the failure of the rescue mission or even a helicopter accident. Based on the classification of helicopter emergency rescue missions, this study focuses on the rescue needs and characteristics of fire extinguishing and medical rescue missions. On the basis of considering the threat of complex terrain environment to rescue missions, through theoretical analysis, modeling and simulation, the A* algorithm is used to plan the feasible path of the helicopter in fire-fighting and medical rescue missions, and the altitude data in ArcGIS is used to obtain the flight height trajectory. By properly planning the helicopter's flight path and altitude trajectory, terrain threats can be avoided to the greatest extent, the success rate of rescue missions can be improved, and the safety of the helicopter and crew can be ensured.Abstract: In recent years, various natural disasters and emergencies have occurred frequently at home and abroad, and the demand for emergency rescue has gradually increased.

Abstract: As climate change intensifies, achieving carbon neutrality has become a global focal point. Carbon Capture, Utilization, and Storage (CCUS) technology, as a crucial tool, offer hope for achieving climate goals by capturing CO2 emissions, utilizing captured CO2, and permanently storing it. This paper analyzes the definition and role of CCUS technology, focusing on the development status in the United States, Europe, and Asia. It delves into challenges related to technological innovation, economic cooperation and investment, social and political factors, and international collaboration. The development of new capture technologies and efficient storage and transportation systems is key to improving the feasibility and economy of CCUS technology. Economic cooperation and investment require close cooperation between the public and private sectors, as well as support from international institutions, to jointly promote the CCUS project. In terms of social and political factors, the improvement of social acceptance and policy regulations is a key bottleneck in the development of CCUS technology, which requires the joint efforts of the government, enterprises, and all sectors of society. The research results indicate that through comprehensive considerations such as technological innovation and global cooperation, CCUS technology is expected to achieve greater breakthroughs on a global scale and become a powerful tool for addressing climate change.Abstract: As climate change intensifies, achieving carbon neutrality has become a global focal point.

Abstract: With the rapid development of China's railways, the total amount of railway transportation has increased rapidly and the operating speed of railways has also been rapidly improved, which puts higher requirements on the reliability and safety of the entire railway network. Foreign object intrusion into railways poses a great threat to the reliability and safety of railway systems. In order to effectively avoid such phenomena, this article proposes a method for detecting foreign object intrusion in railway tracks based on the principle of image processing. Firstly, video data is obtained from the front of the train using the front camera of the train, and image processing techniques such as grayscale, median filtering, and edge processing are used to convert it into clear images to more accurately display the position of the railway tracks. The Otsu method is used for image threshold segmentation, and the Hough transform is used to remove residual impurities line and highlight the outline of the rail line. The background subtraction method in OpenCV library is used for detecting the moving targets, and the Camshift algorithm is used to track images, and determine whether suspicious objects have invaded the rail based on the degree of overlap between the tracked target and the rail. The GUI view provides the overlap ratio between the tracked target area and the rail area to determine whether the object has affected the driving. The effectiveness of the method proposed in this paper was verified through simulation.Abstract: With the rapid development of China's railways, the total amount of railway transportation has increased rapidly and the operating speed of railways has also been rapidly improved, which puts higher requirements on the reliability and safety of the entire railway network.
