Abstract


The technological standard of tunnel monitoring is very high, it needs to continuouslymonitor for a long period of time, measuring various contents, statisticsing complex data. Inmany cases the environment of tunnel monitoring is very difficult.All of that makes thetranditional technical methods difficult to achieve the ideal effectly even after engineeringcomplete.In China, we are late in time of the research on tunnel monitoring,the level oftechnology falls behind the developed countries.The reason makes this are various,includingthe lack of cost and technical means. For a long time the development about the tunnelmonitoring technology is relatively slow.So the implementation of new method helps to solvethe difficulties in the current tunnel monitoring.In recent years, along with the development of new technology, there has been somesuccessful and intelligent case in tunnel monitoring. But generally in our country,theintelligent application proportion our in the process of tunnel monitoring is still low,especially it is difficult to improve the tunnel monitoring in operation. In recent years,wireless sensor network technology rapid development, the emergence of new technologyguarantee the realization of the wireless monitoring network for the tunnel monitoring, solvemany problems in the past, Such as complex circuit, too large energy consumption, toodifficult upgraded and too large engineering cost.In the future, the traffic construction of ourcountry will be steadily enhanced, we will face more technical difficulties, the challenge toimplement tunnel comprehensive monitoring will also increase.In cable monitoring system,the majority of monitoring information content is limited, and the layout of sample point islimited due to line problem, cause the lack of comprehensiveness and objectivity oninformation collection.Cost and performance of cable data transmission medium is difficult tocoordinate, life is limited, once the erosion and damage is easy to affect tunnel monitoring inauthenticity and reliability.Large-scale monitoring also increce the cost of the system, and thecomplex line distribution is not conducive to system’s maintenance and upgrades.Newsensors and wireless Internet research provides the solution for the realization of the wirelessintelligent tunnel monitoring. Compared with traditional monitoring plan, the intelligent monitoring system can greatly shorten the monitoring period of the sampling data, ensureinformation real-time and continuity of nformation collection.It can fully satisfy therequirement of the mass information collection, improved the security of the constructionoperations, makes the new technology applied to practice.Through the analysis to recognize existing shortcomings in the traditional cable tunnelmonitoring system, this paper uses the new type of STM32microcontroller and ZigBeenetworks, provides a design of wireless monitoring of the tunnel. Through consultingliterature, in-depth studing of theory, combined with actual engineering experience of tunnelmonitoring,we design a specific system build plan.The scheme is divided into several parts,each part has excellent performance and clear specification. It effectively solves thedeficiency of current monitoring scheme.
