[0022] In one embodiment, the control mainboard adopts a 32-bit low-power MCU. In this embodiment, the core component of the control box is the control mainboard, which adopts a 32-bit low-power MCU. This MCU has efficient processing capabilities and low power consumption characteristics, and can realize multiple functions such as on-site control, remote control, and time period control. Through the precise control of the MCU, the device can be flexibly adjusted according to different working environments and requirements, realizing the automation and intelligence of water sprinkling and dust reduction. At the same time, the low power consumption characteristics also ensure the stability and reliability of the device during long-term operation.

[0023] In one embodiment, a plurality of mounting holes 17 are provided on the housing 1 .

[0024] The following are the relevant technical parameters of this application:

[0025] (1) Working current: ≤600mA

[0026] (2) Electric valve adapts to water pressure range: 0.2MPa-7.0MPa

[0027] (3) Battery pack intrinsic safety parameters: Uo≤12.75V, Io≤1A

[0028] (4) CAN signal: communication rate 20K

[0029] (5) RS485 signal: communication rate 9.6K

[0030] The following are the relevant applicable environmental conditions for this application:

[0031] (1) The altitude shall not exceed 2000m;

[0032] (2) Ambient temperature: 0℃~+40℃;

[0033] (3) Average relative humidity: ≤95% (+25°C);

[0034] (4) Ambient noise: ≤75dB;

[0035] (5) Atmospheric pressure: 80 kPa ~ 106 kPa;

[0036] (6) In situations where there is no significant vibration or impact;

[0037] (7) There is no corrosive gas or steam that may damage insulation;

[0038] (8) No dripping water or liquid intrusion;

[0039] (9) Places with explosive gas environments such as methane and coal dust.

[0040] Working principle: First of all, the core component of the control box is the control motherboard, which uses a 32-bit low-power MCU and can realize multiple functions such as on-site control, remote control, and time period control. Through the precise control of the MCU, the device can be flexibly adjusted according to different working environments and needs.

[0041] The front panel of the device is equipped with a display window and a rectangular keyboard, so that the user can intuitively see the working status, delay time, working time period, working mode, power, ball valve opening, wireless binding information and other parameters of the device, and set and adjust the parameters through the rectangular buttons. The display window corresponds to the display screen on the control mainboard to ensure real-time update and display of information.

[0042] There are two sets of reducers inside the control box. The output end of the reducer is connected to the ball valve, which is connected to the water circuit and the air circuit respectively. When water spraying is needed to reduce dust, the control motherboard will send instructions to the reducer, and the reducer will rotate to control the switch of the ball valve to open and close the water circuit. At the same time, the role of the air circuit is to mix with the water circuit, so that the water is sprayed out in a mist form, achieving a better dust reduction effect.

[0043] The control box also has wireless control and time period control functions. When there are few obstacles at the installation location and the wireless communication conditions are good, the device can be remotely controlled through wireless signals without external cables. When there are many obstacles in the underground passage, which is not conducive to wireless signal transmission, external cables can be connected to transmit information and control through wired methods.

[0044] In addition, the control box is also equipped with a battery box, which is fixed to the side of the shell by threaded connection and has a handle for quick battery replacement. The outer edge of the battery box is provided with a limiter, which cooperates with the limiter wire and limiter block on the shell to ensure the stable installation of the battery box. The battery is electrically connected to the control mainboard to provide power support for the device.

[0045] Finally, the control box also has the function of displaying fault status and operating status. When the device is in the watering state, if a wireless signal is received, the watering will stop immediately and automatically turn on after a delay. The delay time can be adjusted within a certain range to meet the needs of different scenarios.

[0046] In summary, the control box of the intrinsically safe intelligent automatic water sprinkling and dust suppression device for mining realizes the automation and intelligence of water sprinkling and dust suppression through the control of MCU and the combination of wireless and wired communication methods, improves work efficiency, reduces maintenance costs, and ensures the safe production of mines.
