The highway is the national traffic artery. The safety and stability of the highways are the guarantees for the safe operation. The highway foundation and slope monitoring system is an important way to understand the running state of the expressway, as well as the vital method to ensure the stability of the highway, as well as the safety of people's lives and property. The use of the on-line monitoring system can effectively solve the problems of long-distance inspection and inconvenient detection at night. The automatic deformation monitoring system could monitor and understand the safety and stability of the highway round the clock.
For the roads built on soft soil roadbed, the most prominent problems are stability and settlement. In particular, the big quantity of loading for vehicles will cause great uneven settlement to the roadbed which seriously affects the conditions of use of the road such as tilt, cracks, even destruction. So, the dynamic observation of settlement and stability of soft soil roadbed is one of the keys to improving the quality of highway construction. The intelligent highway subgrade online monitoring system is the use of Beidou high-precision positioning and related geotechnical sensing monitoring technology to achieve dynamic observation of subgrade settlement and stability, providing scientific and effective monitoring to management departments.
Long-term health monitoring of bridges is an important part of assessing the health status of bridges, ensuring bridge safety and avoiding accidents. The intelligent bridge health online monitoring system is a combination of Beidou high-precision positioning technology and stress, strain, temperature, meteorology, and other sensor monitoring technologies to achieve rapid real-time monitoring of bridge health, provides reliable data basis for the road and bridge maintenance management department. The system has the characteristics of high efficiency, fast and all-weather automatic, which escorts the safe operation of the bridge.
The dams are affected by various natural factors, and its engineering status and operation status are changing at any time. Therefore, the dam must be systematically and comprehensively inspected, and the engineering status should be grasped at any time to analyze and judge the dam body, the foundation, and its shore. The monitoring system for dam provides valuable prototype observation data, and also provides a basis for reservoir reinforcement design and reservoir dispatch maintenance.
The monitoring system for the reservoir reflects the displacement of the landslide body in real time through the monitoring points. The results of each monitoring point are displayed through the visual interface, and the system can be remotely managed and maintained. Decision-makers can grasp the dynamic situation of the disaster source in real time, which effectively helps the government and relevant scientific research units to study and prevent landslide disasters, and ensure the safe operation of the reservoir and the safety of the lives and property of the civilians downstream.
Towers such as power transmission line towers and communication towers are all set up in high-lying areas, even along the ridge. The high rainfall is likely to cause soil erosion, debris flow, and landslides, and the artificial exploitation of the mountains and other phenomena will damage the foundation below the tower, causing the tower to tilt or even collapse. The online monitoring system for tower base settlement is mainly to monitor the geographical parameters of the tower and also the parameters that might cause the inclination of the tower. The wireless network is applied to transmit all relevant parameters to the data center for detailed analysis. If the parameter is abnormal, the data center will immediately send out alarm information in a variety of ways, so that the manager can take necessary precautions against the abnormal point to ensure the safe operation of the transmission line.
