Together with our partners, TR Engineering and Createch, we have developed a specialized solution that allows for monitoring in complete communication blackouts.
The solution consists of several parts: 1. The thermometric braid(thermo braid) is a cable with a reinforced core and temperature sensors connected in series, as well as a connector for connecting to a logger. The temperature sensors are connected to each other by a flexible cable and have a high level of dust and moisture protection. They are installed in special thermometric wells.
2. Thermologger – a device that collects data from the connected thermocos, is able to store the data archive locally, as well as transmit it via long and short radio channels. This device is placed in the head of the thermometric well.
3. The thermologger information reader is a device that is mounted on the car, with receiving and transmitting antennas located on both sides of the car. The device reads data from thermologgers (thermocos) and other sensors as it passes by at a high speed. When the car returns to the station, it also transmits the collected data wirelessly to a special operator's workstation.
4. An inclinometer is a sensor designed to measure the angle of inclination of various objects relative to the Earth's gravitational field. We have installed several inclinometers on the movable supports of the railway bridge.
This entire complex is used for monitoring permafrost soils. Why monitor them? It is believed that permafrost is eternal, but this is not the case. Global warming, as well as human activities, cause these soils to thaw, which can have serious consequences for structures located on permafrost. While these processes are long-term and do not occur immediately, it is crucial to monitor them.
