[0004] After the dust collecting net is opened, no matter how big or small the vehicle passing through the dust collecting net is, it is often completely opened directly, so that the dust cannot be effectively captured when the vehicle passes through. Summary of the invention

[0005] In order to effectively capture dust when a vehicle passes by, the present application provides a control method, system, terminal and medium for suppressing dust by a mining dust collection net.

[0006] In the first aspect, the present application provides a method for controlling dust suppression of a mining dust collecting net, which adopts the following technical solution:

[0007] A method for controlling dust suppression of a mine dust collecting net, comprising:

[0008] When the vehicle arrives at the data collection area, collecting the vehicle's external dimension data, the external dimension data including the vehicle height;

[0009] When the vehicle reaches the planned speed adjustment position, obtaining the current driving speed of the vehicle and sending a uniform speed driving signal to the vehicle;

[0010] Obtaining a reaction distance of the vehicle according to the current driving speed, and rounding up if the reaction distance is not an integer;

[0011] According to the reaction distance, adjusting the opening position of the dust collecting net;

[0012] When the vehicle reaches the open position, the opening speed of the dust catching net is controlled according to a preset uniform speed, so that when the vehicle reaches the dust catching net, the opening height of the dust catching net matches the height of the vehicle body.

[0013] By adopting the above technical scheme, before the vehicle reaches the dust catching net, the vehicle's external dimension data is first collected to determine the vehicle's body height, and then after the vehicle reaches the pre-planned speed adjustment position, the vehicle's current driving speed is obtained, and a uniform speed driving signal is sent to the vehicle, and according to the vehicle's current driving speed, the reaction distance of the vehicle entering uniform speed driving is obtained, so as to further adjust the opening position of the dust catching net, so that after the vehicle reaches the opening position of the dust catching net, the dust catching net is controlled to open, so that when the vehicle reaches the dust catching net, the opening height of the dust catching net matches the body height; when the vehicle reaches the dust catching net, the dust catching net stops moving; because the opening height of the dust catching net matches the body height, the opening area of ​​the dust catching net matches the size of the vehicle, so the dust catching net can effectively capture dust when the vehicle passes.

[0014] Optionally, the step of controlling the opening speed of the dust collecting net according to a preset uniform speed includes:

[0015] When the vehicle reaches the opening position, obtaining a current opening distance between the opening position and the dust catching net;

[0016] The opening speed of the dust collecting net is controlled according to the current opening distance and the uniform speed.

[0017] By adopting the above technical solution, when the vehicle reaches the opening position, the dust collection net opening speed is adjusted according to the current opening distance between the vehicle and the dust collection net and the preset uniform speed, so that the opening action of the dust collection net can be accurately matched with the running rhythm of the vehicle. For example, in some mines where there are a large number of transport vehicles passing through and dust needs to be dealt with, if vehicles frequently enter and exit a specific area, the dust collection net can be opened at the calculated speed at the right time, and will not be opened too early to cause resource waste (such as energy consumption, unnecessary wear of the dust collection net, etc.).

[0018] Optionally, the step of controlling the opening speed of the dust collecting net according to the current opening interval and the uniform speed includes:

[0019] The current opening distance and the uniform speed are input into the pre-constructed opening speed model of the dust catching net to obtain the current opening speed of the dust catching net; the opening speed model of the dust catching net is: , H is the height of the vehicle body, V is the uniform speed, is the opening speed of the dust collecting net, and C is the opening distance between the opening position and the dust collecting net.

[0020] By adopting the above technical solution and accurately controlling the opening speed of the dust collecting net, the dust collecting net can be fully deployed at the right time and at the right speed to form an effective dust collecting barrier. At a reasonable opening speed, the dust collecting net can better cope with the dust airflow caused by the passing of vehicles, so that the dust particles in the airflow have a greater probability of being intercepted and captured, thereby reducing the amount of dust remaining in the air and maintaining a relatively clean environment in the working area.

[0021] Optionally, the step of planning the speed and adjusting the position includes:

[0022] According to the maximum speed limit of the vehicle at the location of the dust collecting net, a maximum reaction distance is obtained, and if the maximum reaction distance is not an integer, it is rounded up;

[0023] According to the maximum reaction distance and the preset redundancy threshold, a speed adjustment point in front of the dust catching net, i.e., a speed adjustment position, is obtained, and the front of the dust catching net represents the side where the vehicle enters; the distance between the speed adjustment position and the dust catching net is the sum of the maximum reaction distance and the redundancy threshold.

[0024] By adopting the above technical solution and reasonably arranging the speed adjustment position, it is possible to avoid the situation where the distance between the speed adjustment position and the dust collecting net is less than the vehicle reaction distance, thereby reducing safety accidents.

[0025] Optionally, the control method further includes: the external dimension data includes vehicle body width;

[0026] Determining the opening width of the dust catching net according to the width of the vehicle body and the position of the dust catching net corresponding to the vehicle travel path;

[0027] The opening quantity and position of the dust catching subnet are determined according to the opening width. The dust catching net is composed of a plurality of the dust catching subnets, and each of the dust catching subnets acts independently.

[0028] By adopting the above technical solution, the opening area of ​​the dust collecting net is further matched with the size of the vehicle, so as to further improve the dust collecting effect of the dust collecting net when the vehicle passes by.

[0029] Optionally, the control method further comprises: the external dimension data comprises vehicle body length;

[0030] According to the vehicle body length and the uniform speed, the required stay time of the dust collecting net is obtained;

[0031] Counting the actual stay time of the dust collecting net;

[0032] Determine whether the actual stay time reaches the sum of the expected stay time and the preset delay time;

[0033] If so, the dust collecting net is controlled to descend at a preset descending speed to be closed.

[0034] By adopting the above technical solution, it is ensured that the vehicle can pass completely.

[0035] Optionally, the control method further includes:

[0036] After the dust collecting net is closed, the spray module is controlled to operate.

[0037] By adopting the above technical solution, the fine water mist generated by the spray can further condense and enlarge the dust particles on the dust collecting net, making it easier to adhere to the dust collecting net instead of floating into the air again, thereby improving the overall dust collecting efficiency and effect of the dust collecting net and preventing the captured dust from being raised again to cause secondary pollution.

[0038] In the second aspect, the present application provides a control system for dust suppression of a mining dust collecting net, which adopts the following technical solution:

[0039] A control system for dust suppression of a mine dust collecting net, comprising:

[0040] A dimension data collection module, used to collect the external dimension data of the vehicle when the vehicle arrives at the data collection area, wherein the external dimension data includes the vehicle height;

[0043] A distance acquisition module, used for obtaining a reaction distance of the vehicle according to the current driving speed;

[0044] A position adjustment module, used for adjusting the opening position of the dust collecting net according to the reaction distance;

[0045] The control module is used to control the opening speed of the dust catching net according to a preset uniform speed when the vehicle reaches the opening position, so that when the vehicle reaches the dust catching net, the opening height of the dust catching net matches the height of the vehicle body.

[0046] By adopting the above technical scheme, before the vehicle reaches the dust catching net, the vehicle's external dimension data is first collected to determine the vehicle's body height, and then after the vehicle reaches the pre-planned speed adjustment position, the vehicle's current driving speed is obtained, and a uniform speed driving signal is sent to the vehicle, and according to the vehicle's current driving speed, the reaction distance of the vehicle entering uniform speed driving is obtained, so as to further adjust the opening position of the dust catching net, so that after the vehicle reaches the opening position of the dust catching net, the dust catching net is controlled to open, so that when the vehicle reaches the dust catching net, the opening height of the dust catching net matches the body height; when the vehicle reaches the dust catching net, the dust catching net stops moving; because the opening height of the dust catching net matches the body height, the opening area of ​​the dust catching net matches the size of the vehicle, so the dust catching net can effectively capture dust when the vehicle passes.

[0047] In a third aspect, the present application provides a terminal, which adopts the following technical solution:

[0052] A computer-readable storage medium stores a computer program that can be loaded by a processor and execute the above-mentioned control method for dust suppression of a mining dust collection net.

[0053] In summary, the present application has at least the following beneficial effects:

[0054] 1.

DETAILED DESCRIPTION

[0064] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the appended drawings of the embodiments of the present invention. Figure 1 -Attached Figure 6 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0065] The first embodiment of the present application discloses a method for controlling dust suppression of a dust collecting net for mining. Figure 1 As an implementation of the control method, the control method may include S110-S150:

[0066] S110, when the vehicle arrives at the data collection area, collecting the vehicle's external dimension data, the external dimension data including the vehicle height;

[0067] S120, when the vehicle reaches the planned speed adjustment position, obtaining the current driving speed of the vehicle and sending a uniform speed driving signal to the vehicle;

[0068] S130, obtaining a reaction distance of the vehicle according to the current driving speed, and rounding up if the reaction distance is not an integer;

[0069] S140, adjusting the opening position of the dust collecting net according to the reaction distance;

[0070] S150, when the vehicle reaches the opening position, controlling the opening speed of the dust catching net according to a preset uniform speed, so that when the vehicle reaches the dust catching net, the opening height of the dust catching net matches the height of the vehicle body.

[0071] Specifically, a 3D laser scanner is installed in the data collection area. When a vehicle passes through the 3D laser scanner, the 3D laser scanner scans the vehicle, so that the vehicle's external dimension data can be obtained through the scanning data. The external dimension data includes the vehicle body width, vehicle body height and vehicle body length. In addition, in other embodiments, the vehicle's external dimension data can also be collected in advance by manually measuring and inputting it into the control system.

[0072] In S120, the speed adjustment position is planned in advance, and the planning step may include:

[0073] According to the maximum speed limit for the vehicle at the location of the dust-catching net, the maximum reaction distance is obtained. If the maximum reaction distance is not an integer, it is rounded up. According to the maximum reaction distance and the preset redundant threshold, the speed adjustment point in front of the dust-catching net, i.e., the speed adjustment position, is obtained. The front of the dust-catching net represents the side where the vehicle enters. The distance between the speed adjustment position and the dust-catching net is the sum of the maximum reaction distance and the redundant threshold.

[0074] Specifically, the maximum speed limit is the speed limit of the road section where the dust collection net is located, which can be pre-input into the control system. For example, if the maximum speed limit is 15km / h, the reaction time from the start of deceleration to the completion of deceleration can be set to 3s, then the maximum reaction distance is 15km / h*3s=12.5m. Since it is not an integer, it can be rounded up to 13m, then the maximum reaction distance is 13m, and the redundant threshold can be pre-set to 5m, so 18m in front of the dust collection net is the speed adjustment position; that is, when the vehicle arrives at this position, the vehicle will receive a uniform speed driving signal and obtain the current driving speed of the vehicle, for example, the current driving speed is 13km / h.

[0075] The reaction time can be obtained by analyzing the historical reaction time of the vehicle from deceleration to constant speed in multiple sets of historical data. Furthermore, the average value of the multiple sets of historical reaction time can be calculated as the setting value of the current reaction time. The redundancy threshold can be set manually.

[0076] The uniform speed is pre-set in the control system. For example, if the uniform speed is set to 10km / h and the reaction time is 3S as mentioned above, the reaction distance of the vehicle is 10km / h*3S. 8.3m, rounded up to 9m. The dust net opening position is the position when the vehicle travels 9m from the speed adjustment position, and the dust net opening position is adjusted according to the reaction distance. If the speed adjustment position is 13m away from the dust net, the distance between the dust net opening position and the dust net is 4m.

[0077] Reference Figure 2 , a specific step of S150 may include S151-S152:

[0078] S151, when the vehicle reaches the opening position, obtaining a current opening distance between the opening position and the dust collecting net;

[0079] S152, controlling the opening speed of the dust collecting net according to the current opening interval and the uniform speed.

[0080] Specifically, the current opening interval and uniform speed are input into the pre-built opening speed model of the dust catching net to obtain the current opening speed of the dust catching net; the opening speed model of the dust catching net is: , H is the height of the vehicle body, V is the uniform speed, is the opening speed of the dust catching net, D is the length of the vehicle body, and C is the opening distance between the opening position and the dust catching net, which is the difference between the speed adjustment position and the reaction distance.

[0081] When following When the dust catching net is controlled to be opened, when the front of the vehicle reaches the dust catching net, the opening height of the dust catching net is equal to the height of the vehicle body, at which time the dust catching net is controlled to stop moving.

[0082] Reference Figure 3 , further, the control method also includes S210-S240:

[0083] S210, obtaining a required stay time of the dust collecting net according to the vehicle body length and the uniform speed;

[0084] S220, counting the actual stay time of the dust collecting net;

[0085] S230, determining whether the actual stay time reaches the sum of the expected stay time and the preset delay time;

[0086] S240: If yes, the dust collecting net is controlled to descend at a preset descending speed to be closed.

[0087] Specifically, when the front end of the vehicle reaches the dust collecting net, timing starts, and when the timing reaches the sum of the required stay time and the delay time, the dust collecting net is controlled to descend and close.

[0088] The delay time should be set to 10s, which can be modified by the back-end staff according to the actual situation. The descending speed can be the same as the opening speed, or it can be greater than the opening speed, so as to facilitate the rapid closing of the dust collecting net and further improve the dust collecting effect of the dust collecting net.

[0089] Furthermore, after the dust collecting net is closed, the spray module can be controlled to operate. The spray module includes a spray head and a related water supply structure. The spray head is installed on the top of the dust collecting net, and the spray head sprays water mist to the bottom of the dust collecting net. In addition, in other embodiments, the spray module can also be controlled to operate after the vehicle reaches the speed adjustment point, and the spray module can be controlled to operate regularly when no vehicle passes by.

[0090] Reference Figure 4 As another implementation of the control method, the control method may further include S310-S320:

[0091] S310, determining an opening width of the dust catching net according to a width of the vehicle body and a position of the dust catching net corresponding to a driving path of the vehicle;

[0092] S320, determining the opening quantity and position of the dust collecting subnet according to the opening width, the dust collecting net is composed of a plurality of dust collecting subnets, and each dust collecting subnet acts independently.

[0093] Specifically, the dust-catching net is composed of a plurality of dust-catching subnets, the number of which is not less than three, and each dust-catching subnet is independently controlled to be rolled up. For example, the dust-catching net is composed of three dust-catching subnets, and the driving path of the vehicle passes through the middle dust-catching subnet; if the width of the vehicle body is less than or equal to the width of the middle dust-catching subnet, only the middle dust-catching subnet needs to be opened, and the dust-catching subnets on both sides do not need to be opened; if the width of the vehicle body is greater than the width of the middle dust-catching subnet, all three dust-catching subnets need to be opened.

[0094] The implementation principle of this embodiment is:

[0095] When the vehicle arrives at the data collection area, the vehicle's external dimension data is collected, and then when the vehicle arrives at the planned speed adjustment position, the vehicle's current driving speed is obtained, and a uniform driving signal is sent to the vehicle, and the vehicle's reaction distance is obtained according to the current driving speed, so as to adjust the opening position of the dust catching net according to the reaction distance, and then when the vehicle arrives at the opening position, the current opening distance between the opening position and the dust catching net is obtained, and the current opening distance and the uniform speed are input into the opening speed model of the dust catching net to obtain the current opening speed of the dust catching net, and the opening of the dust catching net is controlled according to the current opening speed; when the front of the vehicle arrives at the dust catching net, the dust catching net is controlled to stop moving, and the actual stay time of the dust catching net is counted, and it is judged whether the actual stay time reaches the sum of the expected stay time and the delay time. If so, the dust catching net is controlled to descend at the descending speed. After the dust catching net is closed, the jet module can be controlled to run to clean the surface of the dust catching net.

[0096] Based on the above method embodiment, the second embodiment of the present application discloses a control system for dust suppression of a mining dust collecting net. Figure 5 As an implementation of the control system, the control system may include:

[0103] In addition, the distance acquisition module 104 will also acquire the current opening distance between the opening position and the dust catching net when the vehicle reaches the opening position, and the control module 106 will control the opening speed of the dust catching net according to the current opening distance and the uniform speed.

[0104] Furthermore, the control system may also include:

[0105] The duration acquisition module 107 is used to obtain the required duration of the dust collecting net according to the vehicle body length and the uniform speed; and to calculate the actual duration of the dust collecting net;

[0106] The judgment module 108 is used to judge whether the actual stay time reaches the sum of the expected stay time and the preset delay time; if so, the control module 106 controls the dust collecting net to descend at a preset descending speed to close. In addition, after the dust collecting net is closed, the control module 106 also controls the jet module to operate to clean the surface of the dust collecting net.

[0107] Reference Figure 6 As another embodiment of the control system, the control system may further include:
