A1 introduces IoT solution to control bridge safety

Together with Qulix Systems, A1 released a new solution for remote bridge safety control, an inclinometer, which measures the angle of inclination of objects and transmits data over its NB-IoT network. This instrument will help predict possible incidents in both traffic and construction industries, as well as timely respond to them.

The solution is based on SIM chips and the NB-IoT network from A1, which allows transmitting data remotely and monitoring the condition of bridges, buildings and other objects even in the most hard-to-reach places.

The unique solution represents a small instrument and platform developed by Qulix Systems. It is installed directly on the measurement object at the point to be monitored, for example, in the middle of the bridge floor. It measures the angle of inclination and transmits a data packet over the NB-IoT network to the platform where the information is processed: angle corrections are introduced, angular values are converted to metric ones, the installation or measurement height is set, the location on the map is set, etc.

Based on these data, it can be derived that the object began to sag or incline, which means that a collapse or any other incident can be prevented and complete overhauls can be timely scheduled. When the limits are exceeded, the instrument sends a notification, for example, to e-mail or an instant messenger, therefore, it is not always necessary for employees to visit the site, which optimizes costs.

The first pilot project of the solution was launched at the A1's base station to monitor the roll of the mast of the base station. The second one was launched together with RUE "Vitebskavtodor" to measure vibrations and sagging of bridge plates. Both pilot projects were launched successfully and showed that the instrument can withstand large daily temperature differences and works without interruption.

Unlike other inclinometers, the joint development by A1 and Qulix Systems does not require power connection and can transmit data remotely. The energy efficiency of the instruments ensures their autonomous operation for three years. Besides, they do not have any specific fastening requirements, which reduces the installation time to literally five minutes.
