洋塘大桥为独塔双索面内倾式斜拉桥,桥梁总长度为 607 m.主塔采用H形结构,主塔高度 65 m,共设有 17条拉索,其中1-8 号为索导管、9-17号为钢锚箱.为避免拉索与导管口发生碰撞,提高施工进度,索导管与钢锚箱的精准定位十分重要.该文结合实际工程和施工条件,提出索导管三维坐标定位方法,并研究出导管口精密定位装置及钢锚箱安装技术,以保证索导管和钢锚箱的精准快速施工.
In response to the differences and instability of gesture action signals,this paper proposes a gesture recognition method based on capacitive sensors and designs a device that can recognize gestures.The device collects and combines gesture signals features,to automatically locates and intercepts effective data of one single gesture.After preprocessing and feature extraction,it achieves real-time recognition of specific gestures,and complete the function of fighting between"1,2,3,4,5"and"Rock,Paper,Scissors"for punching and guessing.Before using the device,different keys are used to control the corresponding boxing and guessing training,and the intercepted data are recorded.After completing the training,the device can adaptively realize the gesture recognition of different people.
Highway mechanical and electrical equipment plays an important role in highway operation,but its maintenance and management is faced with challenges.In order to improve the maintenance efficiency and management level,first of all,strengthen the introduction and training of mechanical and electrical equipment maintenance personnel,through recruitment and cooperative training to improve the professional skills and knowledge of employees.Secondly,optimize the setting and management mode of maintenance organization,establish a perfect maintenance organization system,introduce advanced maintenance management concept and mode,improve maintenance efficiency and prolong the service life of equipment.In addition,enhance the safety awareness of mechanical and electrical employees,strengthen safety training and educational activities,strictly implement the safety management system,and ensure the safe operation of employees.At the same time,an information management system is established to realize the management and sharing of equipment files,maintenance records,fault repair and other information,so as to improve management efficiency.Through the above measures,we can improve the operation efficiency of the equipment and ensure the safe and stable operation of the highway,so as to provide the public with a higher quality and more secure travel environment.
A routing algorithm of Vehicular Ad Hoc Network based on geographical location and node trust value is designed.When transmitting data,the routing algorithm first obtains the geographical location information of the destination node and the neighbor node through beacon broadcasting,and then the node calls the forwarding algorithm to forward the data packet according to the collected geographic location information.The routing algorithm uses two forwarding strategies,greedy forwarding strategy and modified forwarding strategy,and obtains the average end-to-end delay and packet loss rate of the routing algorithm in a specific situation through experimental simulation.The effects of the number of vehicle nodes and the maximum speed of vehicle nodes on the performance of the routing algorithm are analyzed.
In order to solve the shortage of engineers in the process of container crane debugging,optimize the utilization of existing resources and improve the efficiency of construction engineering,the safety of remote debugging operation is realized.A series of advanced technical means are adopted,including video image monitoring,industrial control computer control system,remote intercom equipment and individual equipment,etc.,using 5G dedicated network cable to work together to achieve remote debugging.The results show that the debugging scheme of remote container crane successfully deals with the problem of shortage of engineers,optimizes the working environment of engineers,and reduces the safety risk during debugging.This shows that by adopting remote debugging operation,we can effectively make use of the advantages of modern technology and improve the efficiency of automatic project debugging,thus contributing to the sustainable development of the engineering field.
