[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] In an exemplary embodiment, Figure 1As shown, a method for controlling watering in a coal open-air storage yard is provided. The method is executed by a computer device, and can be executed by a computer device such as a terminal or a server alone, or by a terminal and a server together. In the embodiment of the present application, the method is applied to a server as an example for explanation, and includes the following steps S1 to S5. Among them:

[0022] S1: Obtain environmental data of the open-air coal storage yard in real time, including temperature, humidity, wind speed, rainfall, etc.

[0023] S2: Determine the watering strategy of the global spray gun according to the environmental data. Specifically, it includes: determining the watering time interval and starting conditions of the global spray gun according to the environmental data; determining the watering strategy of the global spray gun according to the watering time interval and starting conditions of the global spray gun.

[0024] S3: Obtain dust monitoring data of open-air coal storage yards in real time.

[0025] S4: Determine the watering strategy of the individual spray gun according to the dust detection data and the basic judgment decision table of the individual spray gun, specifically including: obtaining the basic judgment decision table of the individual spray gun to determine the start-up conditions of the individual spray gun; determining the dust susceptibility level of the material pile according to the dust detection data; determining the watering time interval of the individual spray gun according to the dust susceptibility level of the material pile; determining the watering strategy of the individual spray gun based on the watering time interval and start-up conditions of the individual spray gun.

[0026] S5: Sprinkling water on the open-air coal yard according to the watering strategy of the global spray gun and the watering strategy of the individual spray gun.

[0027] In a specific embodiment, step S2 specifically includes:

[0028] This application uses a decision table to illustrate the watering strategy of the global spray gun, and the decision table is shown in Table 1. Taking the third column in Table 1 as an example, the values ​​of the four judgment conditions are 0010, that is: not winter, ≥-10 degrees, sunny, open-air storage yard, and the system response is to spray 6 times (basic value). Taking the eighth column as an example, the values ​​of the first two judgment conditions are 11, and the remaining two conditions are arbitrary values, that is: winter, <-10 degrees, the system response is to stop scheduled watering. Other similarities will not be explained one by one.

[0029] In case of high temperature, dryness and strong wind, the waiting time will be reduced by 60 minutes, otherwise it will be increased by 60 minutes.

[0030] When receiving an early warning, we will immediately start watering the entire open-air storage yard on the basis of the current scheduled watering, reducing the queuing time for spray guns in the entire yard by 60 minutes. In heavy pollution weather, it will be reduced by 120 minutes, and watering will be continuous when the level rises.

[0033]

[0034] In a specific embodiment, step S4 specifically includes:

[0035] For each spray gun station, in addition to being controlled by the global spray gun watering strategy, it is also controlled by the individual spray gun watering strategy. The individual spray gun watering strategy includes basic judgment and pile factors.

[0036] The basic judgment decision table for a single spray gun is shown in Table 2. The input conditions in the basic judgment decision table include manual watering instructions, timed watering instructions (i.e., the spray gun start sequence under the guidance of the global strategy, which is "1" after reaching the sorting), sensor-sensed dust, start against the wind, whether it is prohibited to spray (such as large machine occupancy, maintenance, etc.), and whether it exceeds the upper limit of starting. For example, the judgment logic of the third column is that if there is a manual watering instruction and the spray gun reaches the upper limit of the start number, the timed watering queue is temporarily stopped and manual watering is started immediately; the judgment logic of the fifth column is that if the timed watering sequence should start watering, but the current start of the spray gun is greater than the upper limit, it will be queued and wait; the judgment logic of the seventh column is that when there is no manual watering instruction, if the dust exceeds the threshold, regardless of the sorting, the timed watering is suspended, and the dust area is expanded according to the wind direction. Sprinkling, and so on.

[0038]

[0039] The stockpile classification strategy is to classify the stockpile into five levels according to the dust-prone properties. All stockpile properties are set to level three by default. The classification can be done manually or automatically. The classification strategy is as follows:

[0040] (I) Before the scheduled watering plan is normally executed, if dust is detected manually or by on-site sensors (due to the small number of sensors in this solution, it is difficult to function), the dust susceptibility level of the pile will be increased; if dust is not found within a week, the dust susceptibility level will be lowered; if the type of coal in the pile changes (manual entry or reading of production data is required), the default level 3 attribute will be restored.

[0041] (ii) Manual grading can be done by production personnel according to their knowledge of coal types. By recording and analyzing the dust emission data of coal types, a database of coal type dust emission properties is formed, which is used to automatically grade known coal types.

[0042] See Table 3 for detailed watering strategies for the dust-prone grade of the pile:

[0043] Table 3

[0044]

[0045] In a specific embodiment, the spray gun in the present application is not started on rainy days. After the rain, the moisture content of the spray gun can be set to remain constant for a period of time according to the rainfall and evaporation coefficient, that is, all spray guns stop spraying water to avoid aggravating the drainage of the yard and unnecessary watering.

[0046] In this application, when the wind speed is greater than level 4 (adjustable), the water pump pressure is increased, and the preset value is: 0.8 MPa for daily use and 1.0 MPa for strong winds. In addition, when the wind speed reaches a certain speed, the system pressure can be automatically increased, and the wind speed condition value and the pressure value reached can be changed on the host computer.

[0047] In a specific embodiment, the present application reduces the start of watering against the wind by monitoring the wind direction. When the wind speed reaches a certain value (the wind speed condition value can be changed on the host computer), the single-side spray gun is automatically sprayed according to the wind direction (especially east wind and west wind).

[0048] In a specific embodiment, the present application reserves the linkage interface for watering at the bottom of the tipping area and the large machine. The watering water volume along the tower belt conveyor, large machines, and the bottom of the tipping machine is introduced into the system, which is convenient for knowing the existing coal watering situation and accurately controlling the yard watering. Avoid watering at the location of the large machine, the site where there is maintenance, and the empty site. After the large machine is cleared and the maintenance is completed, additional watering is required later.

[0049] In a specific embodiment, the present application adjusts the watering strategy in advance based on the weather forecast information obtained in advance, such as strong wind, rain, and snow. In winter, ice after watering poses a safety hazard, and the amount of water to be sprinkled is controlled.

[0050] In a specific embodiment, data from three ambient air particulate monitoring stations are recorded in real time to evaluate the effectiveness of dust suppression strategies and form a closed-loop control.
