[0023] As shown in the figure, an intelligent spray dust removal system for an underground factory building includes a mobile platform 1 and a plurality of dust sensors 11. The mobile platform 1 is equipped with a driving device and a control box 3. The driving device is electrically connected to the control box 3. After receiving the signal from the control box 3, the driving device drives the mobile platform 1 to move in a directional and variable speed manner.

[0024] The driving device is arranged on the lower surface of the mobile platform 1, and the driving device includes a driving box 2, a power wheel 13 and an auxiliary wheel 14. The power wheel 13 and the auxiliary wheel 14 are symmetrically arranged on both sides of the mobile platform 1. The driving box 2 is fixed to the bottom of the mobile platform 1 close to the side of the power wheel 13. A servo motor 15 is installed inside the driving box 2. Transmission rods 16 are connected to both ends of the servo motor 15. The transmission rod 16 runs through the driving box 2 and is connected to the power wheel 13 at both ends. It can drive the mobile platform 1 to move in the underground factory with directional speed change for dust removal.

[0025] The mobile platform 1 is equipped with a water storage tank 4, a partition box 8 and a spray head 5 from bottom to top. The spray head 5 is connected to the water storage tank 4 through a soft water pipe 7, and the soft water pipe 7 is fixedly connected to a water pump 6. The water pump 6 is arranged in the partition box 8, and the control box 3 is electrically connected to the water pump 6 and controls its operation.

[0026] In addition, a rotating seat 10 electrically connected to the control box 3 is provided on the upper surface of the partition box 8, and the spray head 5 is fixed on the rotating seat 10 through the rotating shaft 9. The rotating shaft 9 and the rotating seat 10 can receive the signal of the control box 3 and rotate. A plurality of dust sensors 11 are arranged at equal intervals, and the dust sensors 11 transmit dust information to the control box 3 through the communication module 12, and the control box 3 transmits it to the cloud server in real time.

[0027] The control box 3 is arranged on the upper surface of the water storage tank 4 and is fitted with the side wall of the partition box 8. A single chip microcomputer 17 is installed inside the control box 3, and the single chip microcomputer 17 contains a central processing unit of the model STM32. A power supply 18 is fixedly installed at the bottom of the single chip microcomputer 17, and a display screen 19 is arranged on the outer wall of the control box 3.

[0028] Specifically, the dust sensor 11, the control box 3 and the cloud server are all connected to a LTE-M dedicated network with a working frequency band of 1.8GHz. The dust sensor 11 is fixed to the ground by a support rod, with a height of 1.5 to 2m from the ground. Multiple dust sensors 11 are arranged at equal intervals, with a spacing of 2 to 5m, and their positions can be adjusted by the support rod.

If they work normally, the system can be deployed at the blasting site of the underground factory building and wait for the blasting to start.

[0032] S2. When blasting starts, the dust sensor 11 detects the dust content in the current environment in real time, and the information is summarized by the control box 3 and uploaded to the cloud server. When the conditions for dust removal are met, the cloud server transmits the command to the drive box 2 through the control box 3, and the drive box 2 controls the servo motor 15 to rotate, and transmits the torque to the power wheel 13 through the transmission rod 16 and drives the mobile platform 1 to make the mobile platform 1 reach the specified position.
