Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as figure 1 In the embodiment shown, the liquid level measurement and control system of a glass melting furnace includes: a black circular marker brick 3 , a digital camera 6 , an arm industrial control board 8 , a D / A converter 9 , a digital feeder 10 , and a touch screen 11 . The black circular marker is installed on the pool wall of the parapet 1, and a peephole 5 is opened on the opposite side of the pool wall. The digital camera 6 is installed in the camera cooling water jacket 7, and the cooling water jacket is fixed outside the peephole 5. At about 0.5m, the digital camera 6 is connected to the arm industrial control board 8 through the usb interface, and the arm industrial control board 8 is connected to the digital feeder 10 through the D / A converter 9 and connected to the touch screen 11 through the I2C bus.

Abstract

The invention provides a glass melting furnace liquid level height measuring and controlling method based on machine vision. A digital camera (6) collects images in a melting furnace through a peephole (5), the images are transmitted to an arm industrial control board (8) through a USB interface, the images are processed and the liquid level height is obtained in the arm industrial control board (8), the liquid level height and the images are displayed on a touch screen (11), the deviation e and the deviation change ec are calculated according to the designated liquid level height and the real-time liquid level height, a fuzzy PID algorithm is used for obtaining a suitable material feed speed, finally a speed control signal is sent to a digital material feeder (10) by the arm industrial control board (8) through a D/A converter (9), the feed speed is changed, and the control over the glass liquid level height is realized. The liquid level height in the glass melting furnace can be precisely measured and controlled, and high-quality glass liquid is provided for glass forming.

Description

technical field [0001] The invention relates to the technical field of measuring and controlling the liquid level height of a glass melting furnace, in particular to a method for measuring and controlling the liquid level height of a glass melting furnace based on machine vision. The fuzzy PID algorithm realizes the automatic control of the glass liquid level height in the glass melting furnace, which can measure and control the liquid level height in the glass melting furnace conveniently, accurately and stably Background technique [0002] The fluctuation of the glass liquid level in the glass melting furnace can not only accelerate the erosion of the pool wall bricks, but also seriously affect the molding operation. When the fluctuation is severe, overflow will occur, corrode breast wall bricks and small furnace floor bricks, and shorten the service life of the glass melting furnace. Therefore, stable control of the height of the glass liquid level in glass production is...
