Access Method for Traffic Infrastructure Monitoring Point Data Based on Virtual Gateway
To address the challenges posed by the diversity of sources,structures,and protocols in transportation infrastructure monitoring point data,this study analyzes the requirements for data access and proposes a virtual gateway for the access of monitoring point data within a transportation infrastructure based on the Netty architecture.The study describe in detail the configuration methods and cluster allocation strategies for integrating monitoring points through the gateway,and it defines the data transmission formats under protocols such as the HyperText Transfer Protocol(HTTP),Transmission Control Protocol(TCP),and User Datagram Protocol(UDP).The study also designs an encoding and verification mechanism for data transmission messages.Through enhanced real monitoring data samples,the performance of the virtual gateway is evaluated using distributed message simulation tools.The findings reveal that the virtual gateway facilitates unified access to multipoint and multiprotocol transportation infrastructure monitoring data,achieving data access and storage time of 8.14 s and 9.75 s per hundred million records,respectively.The average time for data traceability is 2.96 s,thus showing the gateway's capacity to handle monitoring data of points at the billion-scale level.This capability significantly supports the research and application of digital monitoring and transportation infrastructure analysis.
