  • Jingzhang Tunnel-Structural Data Monitoring System


    The project is led by Beijing Huajian Company and adopts the Internet of Things Intermediate Data Access System designed by our company to conduct comprehensive data monitoring of the structure in the entire tunnel.

    During tunnel excavation, or in the periphery or inside the tunnel, a large number of sensors such as displacement, inclinometer, and settlement are deployed. The number of sensors is very large. Generally, 485 limited output mode is used. Power consumption, the entire tunnel will be covered with a large number of power lines and signal lines, and the internal environment is complex, the number of sensors in 485 series is more, it is very prone to data instability, our company fully considered the design of the IoT intermediate system In various application scenarios, in addition to the low-power design of the terminal, the terminal has a power output management function, which can perform instant power on and off control management of the sensor, and wirelessly transmit data. The data is summarized by a unified gateway. In order to ensure stability during transmission, we adopt wireless ad hoc network technology, and each node is a gateway to ensure stability in complex electromagnetic environments.
