Embodiment Construction

[0050] Figure 1 to Figure 6 It is a specific embodiment of the present invention. Such as image 3 shown. 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 at an inclination, take the point E radar as an example, where Ee is the radar E inclination measurement path, ee′ is the vertical distance from the inclination radar E to the material level measurement point e contour, and after knowing the distance from the radar to the material level After the distance Ee, according to the Pythagorean theorem and the position a...

Abstract

The invention discloses a dynamic three-dimensional monitoring system and a detection method for the shape of a charge surface of a blast furnace, which belong to the fields of electronic measurement technology and computer three-dimensional technology. The system includes: radar (1), sleeve (2), valve (3), sleeve (4), blast furnace (5), the radar is installed at the flange connecting the sleeve; a set of radar data acquisition unit (7) The imaging system consists of 24 signal access terminal boards and a data acquisition card connected to the terminal board installed on the bus of the industrial computer; an industrial computer and its supporting three-dimensional monitoring software for blast furnace charge level (8). The detection steps are: the radar (1) communicates with the data acquisition unit (7) in real time, and the computer converts the value measured by the inclination into the vertical height value of the charge surface of the blast furnace, and sends it to the computer imaging system (8). Size parameters to generate the surface data of the required 3D layer. The invention has the advantages of solving the problem of online real-time monitoring of the material level inside the blast furnace under the harsh working conditions of high temperature and a large amount of dust.

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 ...
