[Abstract]:The inclinometer can accurately monitor the internal deformation of the tailing dam body and provide visual data information for judging the deformation trend and deformation rate of the dam body. At present, it has been widely used in the safety monitoring of various tailing reservoirs. Based on high precision angular velocity, acceleration and electronic compass sensor, an intelligent digital inclinometer is developed in this paper. The development of the inclinometer is mainly divided into the following three parts: (1) the installation error of the three sensors is studied, and the method of eliminating the installation error is designed; A quaternion-UKF algorithm is proposed and a quaternion-unscented Kalman filter is designed to improve the measuring accuracy of the intelligent digital inclinometer. The automatic measurement of azimuth and inclination angle of tailing dam body is realized. (2) the hardware circuit of intelligent digital inclinometer is designed. The hardware of the system is mainly composed of power circuit, signal acquisition and processing circuit, sensor control circuit, CAN bus circuit and so on. The microprocessor uses STM32F407 chip to collect, process and record data, and CAN bus is used as data transmission mode. Improve the anti-interference ability and transmission distance of the system. (3) the intelligent digital inclinometer system single-chip computer program and upper computer monitoring system design. The monitoring system is developed on VS platform with C # language. The communication module, data processing module and display module are written. The intelligent digital inclinometer is applied to the on-line monitoring of the dam body deformation in the tailings reservoir. The deformation data of the dam can be collected in real time and transmitted to the upper computer by CAN bus to display the deformation information of the tailings dam. Through the system test, the intelligent digital inclinometer designed in this paper meets the technical requirements. In practical engineering application, the problems of tailings dam can be found in time, which has a certain reference significance for the dam body survey and early warning of tailing dam.
