A computer vision-based method for calculating the volume of stacked goods within a regular cube space is disclosed. This method trains a neural network for semantic segmentation using the projected images of the stacked goods on both sides of the cube to obtain a model for calculating the projected area of ​​the stacked goods. This model is then used to calculate the projected area of ​​the collected image data to determine the volume of the stacked goods within the regular cube space. This method avoids the problems of human error and subjective judgment inherent in traditional manual observation methods, and also avoids the drawbacks of instrument measurement methods, such as high equipment costs and maintenance expenses, and susceptibility to environmental interference. It enables accurate and efficient real-time calculation of the volume of stacked goods within a regular cube space.

The invention belongs to the technical field of medicinal chemistry, and particularly discloses ergosterol of a spherical crystal and a preparation method thereof. The preparation method comprises the following steps: heating and mixing ergosterol and ethyl acetate to obtain a mixed solution; and cooling the obtained mixed solution to a crystal growing temperature, growing the crystal, and filtering after the crystal growing is finished, so as to obtain the ergosterol of a spherical crystal. Compared with traditional flaky or needle-shaped crystals and spherical crystals prepared by other methods in the market, the ergosterol of the spherical crystal prepared by the invention has good fluidity, and a series of problems caused by material addition can be greatly improved, so that the industrial production cost is reduced, and the economic benefit is increased.

A communication controller with an automatic spraying function belongs to the technical field of coal mine spraying, and input terminal strip wires DC24V-and I2.0 of a PLC (Programmable Logic Controller) in the communication controller are connected with a magnet type sensor. And a 127V connecting wire of the PLC is connected with a power supply binding post of the electric ball valve and a normally open connecting wire C end of the relay. And a Q0.5 terminal of the PLC is connected with a Q0.5 terminal of the relay. And the normally open terminal G of the relay is connected with the other power binding post of the electric ball valve. The magnet type speed sensor is arranged above the belt conveyor, and the magnet is hung below the magnet type speed sensor. An original outsourcing main control box of an automatic spraying device is omitted, a PLC in a communication controller used for controlling the rubber belt conveyor is used for controlling, meanwhile, an original electronic touch sensor is changed into a magnet type speed sensor to achieve the automatic spraying function, the equipment failure rate is reduced, the control reliability is improved, funds are saved, and safe operation of equipment is guaranteed.
