Wireless Monitoring System Design For Highway Tunnel Construction Plane

In recent years, China highway construction experience of the historic great-leap-forwarddevelopment, especially the highway construction acceleration, the long, tunnel and tunnel group ofextensive in every the highway construction. But because of the tunnel construction and constructionconditions of the geological condition is relatively complex, take cover engineering, regulatory difficulties,according to our country "highway tunnel construction technology standard" requirement, must will sitemonitoring measuring project on construction plans to guide the tunnel design and construction. Withmicroelectronics, communication, computer technology development, road traffic and information of thelevel of intelligence is greatly increased. Actively use technology to strengthen the construction of thetunnel means monitoring strength, adopting effective control strategy, and the advanced automationtechnology, establish and perfect the tunnel monitoring system of highway tunnel construction is safe andeffective control of the basic means. In highway tunnel construction wireless monitoring application facedo some technical research and actual combat highway tunnel construction of speeding up the developmentof safe and effective has important significance and role, to guide the tunnel more construction site, ensurethe safety of the tunnel construction to have the important meaning.This paper video monitoring and wireless transmission to a certain research, using video monitoringand wireless transmission technology effectively solve the monitor and control system in differentequipment or close distance data transmission process cannot ensure its flexibility and rationality, and NeiDeng highway construction within monitoring program, for example, to construct the highway tunnelconstruction wireless monitoring system face, realize the dynamic monitoring of the tunnel construction, soas to discover in time the construction technology, safety and quality, and other aspects of the problem andprocessing, and get the complete backup material used for later analysis survey to the safety of the tunnelconstruction to have the important meaning.The paper first video monitoring and wireless transmission technology are introduced in this paper.Video monitoring technology USES mpeg-4video data compression standard of packaging, with minimaldata get the best image quality. Wireless transmission technology is to use RTP agreement and itsassociated agreement RTCP, provide the transmission process required control functions.Secondly, the highway tunnel construction surface of the wireless monitoring system design andimplementation. According to relevant design specification and functions of the system requirements, the monitoring system is divided into the front end, data transmission, the monitoring center three mainsubsystem. Responsible for the construction of the front image collection. Data transmission part of thewireless bridge digital signal to wireless way of transmitting and receiving, packed into the monitoringnetwork. The monitoring center used the multi-level architecture technique, scattered monitoring,centralized management, to every road real-time image shot, finally realizes the tunnel construction projectinformation in a timely, accurate, comprehensive collection and analysis.Finally, the practical application of the system, performance and speed of response with the systemdesign requirements. Verify the video monitoring and with wireless transmission technology build highwaytunnel construction wireless monitoring program, the feasibility of the realization on construction sitetimely monitoring, has some of the engineering application value.
