Abstract

The invention discloses an IMU-based oscillation radar vibration and inclination state monitoring method and system, comprising: adding an inertial measurement device to each radar unit located in a blast furnace, and using the radar unit to scan the material surface information inside the blast furnace; While the unit acquires the material surface distance information in the radial direction inside the blast furnace, the inertial measurement device acquires the radar state information in the same direction; the acquired material surface distance information and radar state information are sent to the monitoring center; The information describes the height of each point on the material surface, monitors the vibration intensity and swing angle of the radar unit in real time according to the radar state information, and records the cumulative angle error of multiple swings, so as to realize real-time monitoring and diagnosis of the state of the radar unit. The invention can monitor the running state of the radar inside the blast furnace in real time, give an alarm to the abnormal running state of the radar, and eliminate the fault in time, so that the blast furnace radar can work more stably and reliably.

Description

technical field [0001] The invention relates to the technical field of blast furnace radar material level monitoring, in particular to an IMU-based vibration and dip state monitoring method and system of a swing radar. Background technique [0002] In recent years, blast furnace production is an important part of iron and steel smelting, and a good shape of the material surface is of great significance to improve production efficiency and reduce fuel ratio. Since a fixed radar can only measure the distance information of a certain point, a mechanical swing radar is used to measure multiple points for material surface fitting. The direct drive swing radar monitoring technology can accurately describe the height of each point on the discharge surface under severe working conditions such as complete darkness and high dust environment, so as to truly reflect the shape of the blast furnace charge surface and realize the transparency and visualization of the furnace charge surface...
