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 surroundings 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, the 485 limited output method is used. The 485 communication method consumes large power and cannot achieve low power. 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 485 serial sensors is more, it is very prone to data instability, our company fully considered the design of the Internet of things 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 adopted wireless ad hoc network technology, and each node is a gateway to ensure stability in a complex electromagnetic environment.
