Embodiment Construction

[0050]1 to 6 are specific embodiments of the present invention. As shown in Figure 3. A, B, C, D, E, F are six blast furnace charge level radars, a, b, c, d, e, f are A, B, C, D, E, F corresponding to the six radars Measuring point. Among them, the radars B, C, D, E, and F of the measuring points b, c, d, e, and f are installed obliquely, and the radar A is installed vertically. The vertically installed radar A can reach the measuring point according to its installation position and the radar. The distance directly obtains the effective measured height value.

[0051] For the radar installed obliquely, take the E-point radar as an example, where Ee is the oblique measurement path of the radar E, and ee′ is the vertical distance from the oblique radar E to the material level measurement point e contour. After the distance Ee, according to the Pythagorean theorem and the position and angle of the radar installation, the accurate radial position Ee′ of the corresponding measur...

Abstract

The dynamic stereo monitoring system and detection method for charge surface shape in blast furnace belongs to the field of electronic measurement technology and computerized 3D technology. The dynamic stereo monitoring system includes radar, sleeves, a valve, a blast furnace, a radar data acquiring unit with a 24 channel signal access terminal board and a data acquisition board, and an imaging system comprising an industrial control computer and complementary monitoring software. The detection process includes the following steps: the real-time communication between the radar and radar data acquiring unit, converting inclined measured data into vertical curve data, and creating the 3D charge surface shape data. The present invention can realize the on-line real-time monitoring of charge surface shape in blast furnace under harsh operation condition.

Description

technical field [0001] The invention belongs to the field of electronic measurement technology and computer three-dimensional technology, and in particular provides a dynamic three-dimensional monitoring system and detection method for the shape of the blast furnace material surface. The radar-based dynamic three-dimensional monitoring system for the shape of the blast furnace material surface is also applicable to other shaft furnaces and other material surfaces. Detection Systems. Background technique [0002] The blast furnace is a large closed reactor with high temperature, high pressure and high dust, and its internal environment is very complicated. Traditionally, the monitoring of blast furnace charge level is generally limited to collecting data with mechanical probes. The main disadvantages of the mechanical probe are: it cannot be measured continuously, and it cannot be measured during the material distribution process; it cannot be tracked in time when the blast ...
