AI Technical Summary
Existing methods for monitoring convergence in subway tunnels are inefficient, have limited accuracy, high equipment costs, and are inconvenient to operate, making it difficult to meet the needs of high-frequency and high-precision monitoring.
A portable subway convergence monitoring auxiliary device was designed, including an auxiliary device slot, a laser rangefinder, and a support leg. The laser rangefinder is stably installed by driving the pressure plate through a screw and a knob. Combined with the support leg, it reduces human interference, automatically saves data, and is powered by two 1.5V batteries.
It achieves efficient and accurate tunnel convergence monitoring, reduces human interference, meets the high-frequency monitoring needs of subway operation, and reduces equipment costs and operational complexity.
