The load, span and pavement width of bridges are constantly increasing, and the structural form is also changing. These basic settings play a huge role in the national economy. However, experts believe that bridges that have been used for more than 25 years will enter an aging period. According to statistics, 40% of the total number of bridges are already in this category, and they are all "aging" bridges. Over time, its number will surely grow. In order to know the health status of the bridge at any time, to provide early warning of unexpected accidents, and to protect the lives and property of the people, bridge health and safety monitoring has become very important. GeoRTK offers the suitable bridge monitoring solution according to this situation .(1) Multiple sensors of the same or different types can be multiplexed in series on a network, and the system is highly integrated.
(2) The measurement accuracy and resolution are high, and there is no human subjective interference.
(3) The host has a built-in 32GB high-performance industrial-grade SD data storage card, which can store raw observation data with a sampling rate of 5 seconds for more than 10 years.
(4) Users can configure system parameters through network, serial port, Bluetooth, WiFi, and LCD panel buttons.
(5) The host of the base station has an automatic reset function. After the host is powered off and restored, it will automatically continue to work according to the original settings, with long-term and stable continuous working ability.
(6) The reference receiver is equipped with intelligent remote control, intelligent remote upgrade and maintenance, and truly realizes the fully automatic monitoring of the intelligent operation system without manual intervention.
(7) The monitoring plan combines the overall and local structural physical and mechanical states of the bridge, the working conditions of important parts and the environmental conditions. The monitoring focus includes the typical bridge section including the main span of the bridge, the key pier and main tower, and the main cable , Environmental quantities, etc.
