Embodiment 2

[0038] Embodiment 2: The difference from Embodiment 1 lies in the spirit level 4 . figure 2 The middle level 4 is an inductive electronic level. The principle of the inductive electronic level: when the base of the level 4 is tilted due to the inclination of the workpiece to be measured, the voltage of the induction coil will change due to the movement of the internal pendulum. The measurement principle of the capacitive level is that a circular pendulum hangs freely on a thin wire. The pendulum is affected by the gravity of the center of the earth and is suspended in a frictionless state. Both sides of the pendulum are equipped with electrodes and the capacitance is equal when the gap is the same. If the level 4 is affected by the workpiece to be measured, the different distances between the two gaps will produce different capacitances and angle differences. figure 2 The middle level detection device 5 is an MCU. Therefore, when the inductive electronic level is in a non-...

Abstract

The invention discloses an underground engineering and deep foundation pit safety monitoring and early warning system. Instruments and equipment in a data monitoring system are directly installed at asite to be monitored generally, when the instruments and equipment are failed in the process of use, if the maintenance is not performed timely, the normal use of a detecting and early warning systemis affected, and the above problem is solved by the system. The system comprises a data monitoring module and an abnormality monitoring module, a power supply end and an output end of the data monitoring module are connected to an input end of the abnormality monitoring module, an output end of the abnormality monitoring module is connected to an alarm module to achieve the purpose of timely finding the failure of the detecting and early warning system for maintenance.

Description
