The automatic dust hood has the structure shown in figure 1, and can realize the positioning and wet tracking of a dust source point of a working surface, so that the dust hood is adjusted to be in an optimal dust collection range, the safe production of the working surface is guaranteed, and the dust concentration is reduced. The following describes how the apparatus implements this workflow.
An infrared sensor (hereinafter referred to as a sensor) in the automatic dust hood system can measure the distance between a dust source point of a working surface and the sensor, but a single sensor cannot realize the positioning of the dust source point 13, so that 4 sensors are arranged in the system. The dust hood comprises a framework air duct 1, a first telescopic support 2, a first sensor 3, a servo motor 4, a second telescopic support 5, a fourth sensor 6, a dust collection port 7, a fixed base 8, a rotatable bottom/9, a second sensor 10, a third sensor 11 and an air duct fixed seat 12;
the framework air duct is connected with a servo motor through a first telescopic bracket, the servo motor is connected with a dust suction port through a second telescopic bracket, the first telescopic bracket is provided with a first sensor, and the second telescopic bracket is provided with a fourth sensor;
the first sensor, the second sensor and the third sensor are dust source positioning sensors, and the fourth sensor is a guiding sensor.
1. Dust source point location
The first sensor, the second sensor and the third sensor in the automatic dust hood system are fixed, so a coordinate system as shown in figure 2 is established by taking the middle point of a connecting line between the second sensor and the third sensor as an origin,
with P1(x1，y1，z1)、P2(x2，y2，z2)、P3(x3，y3，z3) And P4(x4，y4，z4) The coordinates of sensor one, sensor two, sensor three and sensor four are indicated, respectively, and the coordinates of the dust source point are indicated by C (x, y, z). The first sensor, the second sensor and the third sensor can measure the distance between the dust source point and the first sensor, the second sensor and the third sensor, so that an equation can be obtained:
point P1、P2、P2Is known, | P1C|、|P2C|、|P3The value of C | is measured by the first sensor, the second sensor and the third sensor, so that the coordinates (x, y, z) of the dust source point can be obtained through the formulas (1), (2) and (3), namely the position of the dust source point is obtained.
2. Dust source point tracking
After the coordinates of the dust source point are obtained, in order to ensure that the dust suction port is in the optimal dust suction position, the posture of the dust collection cover is controlled by adjusting equipment such as a rotary base, a telescopic bracket, a servo motor and the like, so that the coordinate change of the sensor four is controlled. In order to achieve the best dust collection effect, the following conditions need to be ensured to be met through a control system:
|P4C|-L≤F (4)
x4＝x (5)
z4＝z (6)
in the formula: i P4C | is the distance from the sensor four to the dust source point; l is the distance from the sensor four to the front end of the dust suction port; f is the optimal dust absorption distance of the dust absorption cover.
3. Supplementary notes
The working surface dust source point can change constantly under the actual condition, so the coordinates of the dust source point need to be updated in real time in the working process of the system, and the posture of the dust hood is adjusted by the control system to ensure that the system achieves the optimal dust control state and the dust hood can accurately track and control the dust source point.
Finally, the above embodiments are only intended to illustrate the technical solutions of the present invention and not to limit the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the claims of the present invention.
