Technical Field

The invention belongs to the field of road monitoring, relates to an intelligent comprehensive monitoring system for a road structure, and particularly relates to an intelligent road performance monitoring system based on remote control.

Background

In the process of road operation, road diseases such as ruts, water damage, hugs, cracks, warping and the like often occur due to the influence of factors such as traffic load, environment and the like, and the service performance and traffic safety of roads are seriously influenced. How to accurately monitor the internal performance change of a road structure and take maintenance measures in time has important significance for improving the service performance and driving safety of roads, and the existing road performance detection method has the following problems:

(1) and the real-time monitoring of the road performance cannot be realized. The existing vehicle-mounted or artificial road detection method is used for detecting the performance of a corresponding road under a certain detection frequency, and the performance change of the road cannot be reflected in real time, so that the road diseases which may occur cannot be effectively processed in time.

(2) The detection accuracy is low. General road detection methods, such as radar detection and surface wave detection, determine a possible road fault by emitting a certain radar wave to the surface of a road or exciting a seismic source to obtain the reflection or refraction of the light wave in the road. The method cannot directly change the internal performance of the road, and has more influence factors, so that the accuracy rate is often low.

(3) The performance variation of the road cannot be comprehensively represented. The general detection method can only obtain one or more parameter changes in the road, and cannot comprehensively represent parameters influencing the road structure performance.

(4) Monitoring costs tend to be high. The general wired monitoring method is usually to bury optical fiber or other types of sensors in the road, but the sensors are often damaged under the action of external load or environment, and the sensors are not easy to repair. However, the general wireless monitoring method cannot achieve long-term effective monitoring due to battery energy supply.

(5) The long-term service performance of the road is adversely affected. The external shape, strength and other parameters of the traditional embedded sensor are often greatly different from those of road materials. The stress on the structure is often adversely affected under external loading.

(6) The signal interference between different types of sensors is large. In general, different types of sensors of an integrated monitoring device often interfere with each other, and the quality of signals is adversely affected.
