Application of Linear Displacement Sensor in Bridge Inspection
Application of Linear Displacement Sensor in Bridge Inspection
Bridge engineering is an important aspect of national infrastructure construction, and it is an important link to connect local traffic and promote economic development. After the completion of the bridge, due to the influence of load, climate, environment, vibration, cable force and stress changes, the structural materials of the bridge will gradually be corroded and aged, and the strength and stiffness will gradually decrease.
Long-span bridges are more affected by the above factors, which will not only shorten the service life of bridges, but also lay a great hidden danger for the personal safety of pedestrians. Therefore, real-time monitoring of the health status of bridges and safety assessment based on it are important contents of daily maintenance.
With the progress of society and the development of technology, frontier technologies such as sensor technology, computer technology and communication technology are gradually introduced into the bridge monitoring system, which initially realizes the functions of automatic monitoring and early warning, and can be really used for bridge structural damage and state evaluation for a long time, meeting the needs of bridge maintenance management and operation, providing theoretical basis for scientific management of bridges, and taking into account economic and social benefits.
The linear displacement sensor is a contact measuring instrument. When in use, the sensor directly contacts with each measuring point, and the sensor converts the displacement variation into an electrical signal in time and transmits it to the monitoring and control center. After being collected and measured by the control system, it can predict the running status of the bridge, which can realize synchronous collection, comparison and data storage of all measurements, provide scientific basis for scientific management and monitoring of bridge diseases, and also transmit the signals collected by the system to the Internet. It is the most basic component of the Internet of Things and the most widely used measurement in various bridge monitoring systems at present.
No matter what instrument is used as the detection means, the bridge monitoring system should follow the principles of simplicity, practicality, economy and reliability, and the monitoring points should be arranged according to the requirements of bridge structure and maintenance management, and the monitoring points should be closely related to the safety of bridge structure.
