Abstract

The invention discloses an IMU-based swing radar vibration and inclination angle state monitoring method and system, and the method comprises the steps: adding an inertia measurement device to each radar unit located in a blast furnace, and carrying out the charge level information scanning of the interior of the blast furnace through the radar units; when the radar unit acquires the charge leveldistance information in the radial direction in the blast furnace, enabling the inertial measurement device to acquire radar state information in the same direction; sending the acquired charge leveldistance information and radar state information to a monitoring center; enabling the monitoring center to describe the height of each point of the charge level according to the charge level distanceinformation, monitoring the vibration intensity and the swing inclination angle of the radar unit in real time according to the radar state information, and recording the accumulated inclination angleerror of multiple swings so as to realize real-time monitoring and diagnosis of the state of the radar unit. According to the invention, the operation state of the radar in the blast furnace can be monitored in real time, the abnormal operation state of the radar is alarmed, faults are eliminated in time, and 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...
