[0049] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0051] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more (including two), similarly, "multiple sets" refers to two or more sets (including two sets), and "multiple pieces" refers to two or more pieces (including two pieces) unless otherwise explicitly defined.

[0052] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0053] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0054] Most existing sprinkler systems rely on manual control or one-button automatic spraying. Manual control carries a significant risk of human error, while one-button automatic spraying lacks flexibility in water usage.

[0055] To address the aforementioned technical problems, this application provides a method for controlling dust suppression by spraying coal trucks. This method can capture weather and transport distance data in real time and perform corresponding calculations to determine the minimum amount of water required to achieve dust suppression and cooling effects. Then, based on the calculation results, the coal to be transported is sprayed.

[0056] However, in practice, it has been found that the required water volume varies depending on the weather conditions (mainly humidity and temperature) and the evaporation rate of the sprayed water. Therefore, spraying too little water fails to achieve the desired dust suppression and cooling effect; spraying too much water can lead to disputes between buyers and sellers regarding the moisture content of the coal and also wastes water resources. Furthermore, based on the physicochemical properties of coal, excessive moisture increases the risk of spontaneous combustion, thus excessive water spraying can also pose certain safety hazards.

[0057] Based on this, the method can scientifically and rationally calculate water consumption, using less water for spraying while ensuring sufficient safety in dust reduction, environmental protection, cooling, and flame retardancy, thereby achieving the effect of saving water resources (for example, avoiding water waste caused by the duplication of spraying at the factory and during storage).

[0058] like Figure 1 As shown, some embodiments of this application provide a method for dust control by spraying water on coal transport vehicles. This method includes:

[0059] S101. Before the coal truck starts transporting coal, obtain current environmental information, coal quality loaded in the coal truck, initial moisture content of the coal, and transport distance information.

[0060] S102. Calculate the water consumption for spraying based on current environmental information, the quality of coal loaded in the coal truck, the initial moisture content of the coal, and the transportation distance.

[0061] S103. Control the series electric valves to switch on and off according to the water consumption for spraying to perform the corresponding spraying operation.

[0062] In some embodiments, current environmental information refers to current weather, temperature, humidity, and other information.

[0063] In some embodiments, coal quality typically refers to the sum of the dry basis mass and moisture content of the current coal mine.

[0064] In some embodiments, transportation route information refers to information such as the transportation route, transportation mileage, and transportation time of the coal truck.

[0065] In some embodiments, after step S101, the method further includes:

[0066] Check whether the current environmental information, the quality of coal loaded in the coal truck, the initial moisture content of the coal, and the transportation distance information are entered correctly;

[0067] If all inputs are correct, proceed to step S102;

[0068] If an input error is found, an error message will be issued and step S101 will be re-executed.

[0069] For example, Figure 2 A logic flowchart of a dust suppression spraying method for coal transport vehicles is shown.

[0070] In these embodiments, the method can accurately calculate the amount of water used for spraying based on a variety of practical factors, achieve reasonable spraying, avoid water waste, reduce disputes caused by the moisture content of coal and reduce the risk of spontaneous combustion of coal, and at the same time, it does not require the addition of costly and potentially environmentally harmful chemical flame retardants.

[0071] In some embodiments, obtaining current environmental information, the quality of coal loaded in the coal truck, the initial moisture content of the coal, and transportation distance information includes:

[0072] The weight of the coal loaded in the coal truck is collected when it passes through the weighbridge.

[0073] Obtain current environmental information; this information includes at least temperature and humidity.

[0074] Obtain monitoring data on the moisture content of coal inside the warehouse before loading, and determine the initial moisture content of the coal based on the monitoring data;

[0075] Obtain transportation route information for coal trucks; the transportation route information includes map navigation information from the departure location to the destination location.

[0076] In some embodiments, map navigation information may include or calculate the transportation time required for the coal truck to travel the entire distance.

[0077] For example, when a coal truck passes a weighbridge, the weight of the loaded coal is measured and output to a server. Simultaneously, real-time temperature and humidity data from weather software are captured and used as current environmental information. Additionally, real-time transportation route information recorded or displayed in map software is captured, and transportation time is estimated. Finally, monitoring data on the coal's moisture content inside the warehouse before loading (i.e., the initial moisture content of the coal) is obtained through appropriate devices.

[0078] In these embodiments, the method can comprehensively and accurately collect key information affecting the amount of water used for spraying, providing a reliable basis for subsequent scientific calculation of the amount of water used for spraying, thereby achieving efficient and reasonable dust control through spraying.

[0079] In some embodiments, the amount of water used for spraying is calculated based on current environmental information, the quality of coal loaded in the coal truck, the initial moisture content of the coal, and the transportation distance information, including:

[0080] Calculate the target coal moisture content based on current environmental information, transportation route information, and initial coal moisture content;

[0081] Calculate the rate of change of coal moisture content based on the target coal moisture content and the initial coal moisture content;

[0082] Calculate the water consumption for spraying based on the rate of change in coal moisture content and the mass of coal loaded in the coal trucks.

[0083] In some embodiments, the method can perform integrated calculations based on factors such as temperature, humidity, coal volume, transportation time, and initial moisture content of the coal.

[0084] For example, this method can calculate the target coal moisture content at the server level based on a built-in table formed from data (temperature, humidity, coal volume, transportation time, initial coal moisture content, etc.). Then, the method can calculate according to the following formula:

[0085] Moisture content change rate = target coal moisture content - initial coal moisture content;

[0086] Spraying water consumption = Coal mass × Moisture content change rate / (1 − Moisture content change rate).

[0087] This allows us to calculate the optimal water consumption for spraying. However, the above formula is typically used under ideal conditions, i.e., when the coal is initially in an absolutely dry state.

[0088] Therefore, considering that coal is usually not in a completely dry state initially, the above calculation formula should be adjusted to:

[0089] Moisture content change rate = target coal moisture content - initial coal moisture content;

[0090] Coal dry basis mass = coal mass × (1 - initial moisture content of coal);

[0091] Spraying water consumption = dry coal mass × moisture content change rate / (1 - target coal moisture content).

[0092] In these embodiments, the method can accurately calculate the amount of water used for spraying based on the rate of change in moisture content and the quality of coal, thereby enabling precise control of water usage according to the dynamic changes in the moisture content of coal.

[0093] In some embodiments, controlling the series-connected electric valves to switch on and off to perform corresponding spraying operations based on the spraying water volume includes:

[0094] The amount of recycled water and regular water replenishment should be determined based on the amount of water used for spraying.

[0095] The usage of recycled water and the amount of regular water replenishment are transmitted to the electronic flow meter;

[0096] The electronic flow meter controls the series electric valves to open the corresponding valves for spraying operations.

[0097] In some embodiments, the method uses an electronic flow meter to control valves for spraying.

[0098] In some embodiments, the system using this method is simultaneously connected to a greywater pipeline network, enabling greywater to be used in the sprinkler control of this method. Furthermore, after the greywater pipeline network is connected, the sprinkler system can utilize greywater as much as possible, and only supplement with regular water when greywater is insufficient to meet the demand, further conserving water resources.

[0099] In these embodiments, the method can use recycled water and rationally allocate the usage of recycled water and conventional water, thereby achieving rational utilization of water resources and thus achieving more economical spraying.

[0100] In some embodiments, the electronic flow meter controls the series-connected electric valves to open corresponding valves to perform corresponding spraying operations, including:

[0101] The electronic flow meter controls the series of electric valves to open the corresponding valves for spraying;

[0102] Control the spray heads to move and spray water in the direction of movement from the front to the rear of the vehicle.

[0103] In some embodiments, the method can output the calculated water consumption for spraying to an electronic flow meter, so that the electronic flow meter controls the series electric valve to open and close the valve to start spraying, and closes the valve to stop spraying when the flow rate reaches the target flow rate.

[0104] In these embodiments, the method can use an electronic flow meter to precisely control the opening state of the series electric valves to ensure proper spraying, while controlling the spray head to move in a specific direction to achieve comprehensive and uniform spraying operation on the coal transport vehicle.
