Abstract

The invention discloses a blast furnace burden surface imaging device and system and a measuring method thereof. The device comprises a radar antenna, a frequency synthesizer system, a transceiving system and a signal processor, the transceiving system is in signal connection with the radar antenna; the transceiving system mixes and amplifies frequency modulation signals generated by the frequencysynthesizer system and then transmits the signals to the radar antenna; low-noise noise amplification, filtering and frequency mixing processing are carried out on echo signals received by the radarantenna; the frequency synthesizer system is in signal connection with the transceiving system and provides frequency modulation signals and frequency mixing signals for the transceiving system; the signal processor is in signal connection with the transceiving system and the frequency synthesizer system; and the signal processor performs coherent processing on the echo signals processed by the transceiving system to obtain echo distance and azimuth information of targets, processes the echo distance and azimuth information to obtain height information of the targets, and fits an image of thematerial surface in the blast furnace according to the height information of the plurality of targets.

Description

technical field [0001] The invention relates to the technical field of radar imaging, in particular to a blast furnace material level imaging system device and a measurement method thereof. Background technique [0002] At present, there are many types of level measuring instruments at home and abroad, such as: radar type, ultrasonic type, laser type, heavy hammer type, radio frequency admittance type, capacitive type, etc. The above products are based on the principle of single point measurement. In terms of material level measurement, the application effect is not ideal, and many problems have been exposed. Factors that affect the accurate measurement of traditional single-point level measuring instruments are as follows: 1. The material particles in the powder silo are small, and when the powder is fed into the cabin, it is in a diffuse state, the fine dust is flying, the powder bulk density is small, and there is powder The distinction between powder-free and powder-fr...
