ZigBee-based tunnel automatic monitoring system and monitoring method thereof

Abstract

The invention discloses a ZigBee-based tunnel automatic monitoring system and a monitoring method thereof. The system comprises an automatic data acquisition system, a wireless remote transmission system and a user service platform, wherein the automatic data acquisition system comprises a sensor, a data acquisition system and a short distance wireless transmitting and receiving device; the wireless remote transmission system comprises a base station, a remote wireless transmission device and a server; and the user service platform comprises treatment systems, such as a data analyzing and processing system, an intelligent early warning system and a management center. The monitoring system and monitoring method which are disclosed by the invention have the advantages that a wireless communication technology is adopted, fewer cables are used, damage caused by tunnel construction on the cables is avoided, a large-scale network is adopted for carrying out large-scale point distribution, and a tunnel structure can be monitored, early-warned and evaluated more detailedly and more accurately.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a ZigBee-based tunnel automatic monitoring system and a monitoring method thereof. Background technique [0002] With the rapid development of national construction, the current highway and railway tunnels have some new features: large cross-section, long tunnel, complex geological conditions, and unfavorable ground conditions in front of the tunnel excavation face can easily cause tunnel collapse and water gushing. These factors not only bring great difficulties to tunnel construction technically, but also often cause personal casualties and delays in construction due to unexpected accidents, resulting in huge economic losses. [0003] The current methods and tools used for tunnel monitoring have become more and more limited with the increasing tunnel span or the increasing difficulty of monitoring, and the accuracy and error of monitoring are increasingly unable to meet the requirements. ...

Problems solved by technology

These factors not only bring great difficulties to tunnel construction technically, but also often cause personal casualties and delays in construction due to sudden accidents, resulting in huge economic losses. At the same time, they have also attracted the attention of national regulatory authorities

[0003] The current methods and tools used for tunnel monitoring have become more and more limited with the increasing tunnel span or the increasing difficulty of monitoring, and the accuracy and error of monitoring are increasingly unable to meet the requirements. Furthermore, the current The monitoring method also cannot carry out real-time monitoring, does not have the function of automatic alarm or early warning, and there are factors that affect

[0004] In addition, some conventional monitoring instruments and methods also have some fundamental defects: point measurement, less information; difficult to achieve distributed monitoring, often missing some important information for engineering safety; poor durability; vulnerable to strong Electromagnetic field interference affects measurement accuracy; it is not suitable for harsh environments such as flammable, explosive, high temperature, and lightning strike areas; it is inconvenient for long-distance telemetry and monitoring, etc.
