It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure.

[0021] It should be noted that the user information involved in this disclosure includes, but is not limited to, user device information and user personal information; the collection, storage, use, processing, transmission, provision and disclosure of user information in this disclosure all comply with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0023] The technical solutions provided by the embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0024] Figure 1 This is a schematic diagram of the structure of an air purification system 10 for the driver's cab of a bucket wheel excavator, provided as an exemplary embodiment of this disclosure. Figure 1As shown, the system includes: a fresh air system 11, a controller 12, and a bucket wheel excavator 13. The fresh air system 11 includes: a fresh air fan 111 and a fresh air ventilation duct 112. The fresh air fan is located outside the air-supported membrane coal yard; the bucket wheel excavator is located inside the air-supported membrane coal yard; and the controller is located outside the air-supported membrane coal yard. This disclosure provides centralized control of the fresh air system and controller located outside the air-supported membrane coal yard. This facilitates maintenance while preventing dust from the air-supported membrane coal yard from harming the fresh air system filters, extending filter lifespan, reducing filter replacement frequency, lowering daily maintenance workload and costs, ensuring a relatively stable external environment, reducing system operating energy consumption, and providing a stable airflow to the driver's cab, guaranteeing a more stable positive pressure inside the driver's cab.

[0025] In one optional embodiment, the fresh air ventilation duct is connected at one end to a fresh air fan and at the other end to the driver's cab of the bucket wheel excavator; the controller is located outside the air-supported membrane coal yard and is used to control the fresh air system to adjust the current operating parameters based on the air quality information in the driver's cab, the air quality information in the air-supported membrane coal yard, and the operating information of the bucket wheel excavator.

[0026] In some embodiments of this disclosure, a reel structure is installed on the bucket wheel excavator; the reel structure is equipped with an automatic winding and unwinding mechanism; a fresh air ventilation duct and a control cable are wound around the reel structure, and the cable is connected to the bucket wheel excavator and a controller; the automatic winding and unwinding mechanism is used to wind and unwind the fresh air ventilation duct and the control cable when the bucket wheel excavator moves. The reel structure of this disclosure is equipped with an automatic winding and unwinding mechanism, which synchronously winds and unwinds the duct and cable as the bucket wheel excavator moves on the track, ensuring that the duct is always taut and without redundant accumulation; ensuring smooth delivery of fresh air when the bucket wheel excavator is moving, enabling the bucket wheel excavator to stably receive fresh air at any position on the track, avoiding interruptions in fresh air supply due to duct dragging or entanglement, and ensuring the continuity and reliability of the fresh air supply.

[0027] It should be noted that the air quality information in the driver's cab includes: dust concentration, air pressure, and oxygen concentration; the air quality information in the air-supported membrane coal yard includes: carbon monoxide, dust, and methane concentration; and the bucket wheel excavator's operating information includes: operating position and start / stop status. Current operating parameters include: current fresh air volume, current fan speed, and current filtration mode.

[0028] In some embodiments of this disclosure, a first dust concentration sensor, an air pressure sensor, and an oxygen concentration sensor are installed in the driver's cab. The first dust concentration sensor is used to collect the dust concentration in the driver's cab, the air pressure sensor is used to collect the air pressure in the driver's cab, and the oxygen concentration sensor is used to collect the oxygen concentration in the driver's cab. Inside the air-supported membrane coal yard, a carbon monoxide sensor, a second dust concentration sensor, and a methane concentration sensor are installed. The carbon monoxide sensor is used to collect carbon monoxide in the coal yard, the second dust concentration sensor is used to collect dust concentration in the coal yard, and the methane concentration sensor is used to collect methane concentration in the coal yard. This disclosure uses corresponding sensors in the air-supported membrane coal yard and the bucket wheel excavator driver's cab to collect data for subsequent control of the fresh air system, enabling rapid adjustment of the fresh air system and improving its intelligence.

[0029] In some embodiments of this disclosure, the controller adjusts the current operating parameters of the fresh air system based on air quality information in the driver's cab, air quality information in the air-supported coal yard, and operating information of the bucket wheel excavator. One possible implementation is as follows: when the dust concentration in the driver's cab exceeds a set dust concentration, or the carbon monoxide concentration in the coal yard exceeds a set carbon monoxide concentration, the controller adjusts the current fresh air volume to a first set volume, where the first set volume is greater than the rated volume; when the air pressure in the driver's cab is less than a set air pressure, the controller increases the current fan speed; when the methane concentration in the coal yard exceeds a methane concentration threshold, the controller switches the current filtration mode to a target filtration mode, where the filtration performance of the target filtration mode is greater than that of the current filtration mode; when the bucket wheel excavator is stopped, the controller adjusts the current fresh air volume to a second set volume, where the second set volume is less than the rated volume. It should be noted that this disclosure does not limit the set dust concentration, set carbon monoxide concentration, set air pressure, or methane concentration threshold; adjustments can be made according to actual conditions. The dust concentration is set, for example, 0.5 mg / m³; the carbon monoxide concentration is set, for example, 24 ppm; and the air pressure is set, for example, 50 Pa. This disclosure does not limit the first and second set air volumes, which can be adjusted according to actual conditions. The first set air volume is 120% of the rated air volume, and the second set air volume is 50% of the rated air volume.

[0030] In one exemplary embodiment, the controller automatically determines the operating status and adjusts system parameters based on collected multi-dimensional data. When the dust concentration in the driver's cab is detected to be >0.5mg / m³ or the carbon monoxide concentration in the coal yard is detected to be >24ppm, the fresh air volume of the fresh air system is automatically increased to 120% of the rated air volume; when the air pressure in the driver's cab is lower than 50Pa, the fan speed is increased to maintain positive pressure; when the gas concentration in the coal yard is greater than the gas concentration threshold, the system switches to high-efficiency filtration mode in advance and enhances positive pressure; when the bucket wheel excavator is stopped, the fresh air volume of the fresh air system is automatically reduced to 50% of the rated air volume to achieve energy-saving operation.

S202: Based on the air quality information in the driver's cab, the air quality information in the air-supported coal yard, and the operating information of the bucket wheel excavator, control the fresh air system to adjust the current operating parameters.

[0032] In this embodiment, the executing entity of the above method is a controller. The controller is a core component of an automatic control system, and its main function is to calculate and output control signals based on the deviation between the actual output and the desired output (set value) of the system, thereby driving the actuators to bring the system to or maintain it in the desired state.
