Description

Technical Field

[0001] The present invention relates to the field of air pollutant monitoring, and in particular to an air sampling control method and a control device based on an unmanned aerial vehicle. Background Art

[0002] The current air pollution problem is serious, and there is an urgent need to analyze and monitor various air pollutant emission sources in industrial enterprises. At present, most of them still adopt the method of on-site sampling and transporting them back to the laboratory for offline analysis. However, the on-site conditions of enterprises are complex, the emission sources are numerous and scattered, and the air pollutants are unevenly distributed in a vast space. Some emission outlets are located at high positions, which are difficult to reach manually or pose safety hazards, and it is impossible to obtain representative samples for offline analysis. The flexibility of drones can be of great help in the collection of atmospheric samples, because they can quickly reach any position within a certain height above the ground without restrictions. However, the sampling device carried by the drone is affected by meteorological conditions such as wind speed, and the sampling process is difficult to control.

[0003] Chinese patent CN205280439U discloses an atmospheric sampling device, which relates to the field of atmospheric detection technology. The main purpose of this prior art is to improve the convenience of collecting atmospheric pollutant concentrations. The main technical solution adopted is: an atmospheric sampling device can be installed on a mobile carrier to sample the air to be detected, and the atmospheric sampling device includes: an airflow hood, a pollutant filter core and a mounting part. The first end of the airflow hood has an air inlet, the second end of the airflow hood has an air outlet, and the interior of the airflow hood has a sampling space connected to the air inlet and the air outlet respectively. The pollutant filter core is arranged in the sampling space. The mounting part is arranged on the airflow hood, and is used to mount the atmospheric sampling device on the mobile carrier for mobile sampling. The atmospheric sampling device provided by the prior art has a simple structure and a light weight. It can be carried by a drone to a predetermined area to detect atmospheric pollutants, and is more flexible for air detection in specific dangerous areas. This scheme is a scheme involving a sampling device, which is an improvement on the hardware, but the control process of the scheme is still relatively simple and rough, and it is impossible to adjust the sampling position and sampling process according to the real-time changes of the gas phase at the sampling point, and the accuracy of the sampling results cannot be guaranteed.

[0004] Therefore, there is an urgent need for an atmospheric sampling control method and control device that can not only perform routine sampling according to the sampling plan, but also adjust the sampling position and control the sampling process in real time when there are sudden changes in gas phase conditions such as wind speed, so that the sampling results are more in line with actual needs.

[0028] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. 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. Unless otherwise expressly stated, throughout the specification and claims, the term "including" or its variations such as "comprising" or "including" will be understood to include the stated elements or components, without excluding other elements or other components.

[0030] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0031] In addition, in order to better illustrate the present invention, numerous specific details are provided in the following specific embodiments. It should be understood by those skilled in the art that the present invention can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present invention.

[0032] The atmospheric sampling of the present invention is to perform atmospheric sampling through a sampling container carried by a drone, which is particularly suitable for sampling environments where the discharge port is located at a high position, is difficult to reach manually or has safety hazards, and representative samples cannot be obtained for offline analysis. The drone involved in the present invention has the positioning function of horizontal longitude and latitude and vertical height, can automatically plan a reasonable flight path according to a given target position, has a certain load capacity, can carry a sampling container, a sampling control module, and a power supply module to fly to a given position and hover for atmospheric sampling.

[0033] The sampling container involved in the present invention is connected to the drone and can be assembled and disassembled at any time. After assembly, the relative positions of the two can be kept fixed during the flight. The sampling container can specifically be a metal sampling can of varying volumes, a plastic sampling bag, or a metal sampling tube containing an adsorbent material. An electric valve is provided at the inlet of the container, and the opening and closing of the valve represent the beginning and end of sample collection, respectively. A filter is connected to the front end of the valve, which mainly removes particulate matter in the atmospheric sample. The valve is electrically controlled during the sampling process. After the sampling is completed and the drone is removed, the valve can be manually opened and closed to take the sample.

[0034] The sampling control module of the present invention can communicate with the ground control system wirelessly and communicate with the sampling container and the drone through a signal transmission cable. The sampling control module obtains the sampling task from the ground control system, including but not limited to the sampling position, sampling duration, etc., and then sends the sampling position information to the drone, sends the sampling duration information to the sampling container, records the specific time of the opening and closing of the sampling container valve as the start and end time of sampling, records the actual spatial position information of the drone, and transmits the information back to the ground control system after the sampling is completed.

[0035] The power supply module of the present invention is connected to the drone, sampling control module and sampling container through cables, and is responsible for providing the power required for the operation of each module. It has a charging interface that can be connected to the mains for charging. The power supply module has a power monitoring function, and if the remaining power is insufficient to support a sampling operation, an alarm will be issued to prompt that charging is required.

[0036] The ground control system of the present invention has data transmission, data processing and display functions. The data processing function mainly edits and generates sampling plans according to sampling needs, and can record and store all information of each sampling plan, so as to facilitate the later selection and viewing of the execution status of historical sampling plans.

[0037] Example 1

[0038] like Figure 1 As shown, the atmospheric sampling control method of the present invention comprises the following steps:

[0039] Step S101, establish one or more sampling tasks, determine the sampling points, sampling information, and establish the association between the sampling tasks and the sampling equipment. That is, collect the location information of all points that need to be sampled and analyzed in advance, including horizontal longitude and latitude and vertical height, and then store the point name and location information in the ground control system one by one. When editing the sampling plan, select the point name to automatically call the detailed location information. Assign a unique identification code to the sampling device. Scanning the identification code can obtain the sampling device number and related information. The task association between the sampling device and the sampling point is realized by scanning the identification code and transmitting it to the ground control system. At this time, the sampling device and the ground control system complete time synchronization.

[0040] Step S102, after the drone arrives at the preset sampling point, detect the actual wind speed at the sampling point and compare the actual wind speed with the wind speed threshold. For example, the wind speed threshold can be a strong wind level of 10.8 m / s as needed. If the wind speed at the sampling point is detected to be lower than the wind speed threshold, execute step S103; if the wind speed at the sampling point is detected to be higher than the wind speed threshold, execute step S104;

[0041] Step S103, the sampling device performs sampling at a preset sampling point (i.e., the coordinate position that has been determined when the sampling task is established) according to preset sampling information (i.e., the sampling device identification number, sampling start time, sampling end time, etc.);

[0042] Step S104, after completing the predetermined sampling task, i.e., sampling at the preset sampling point, the sampling device performs secondary sampling at a first preset distance downstream of the airflow. The first preset distance can be set in advance as needed. If the wind speed threshold is set to a strong wind level of 10.8 m / s, the first preset distance can be set to 3 to 5 m.

[0043] Since the airflow environment at high altitude is relatively complex, the wind speed and wind direction may change in real time during the sampling process. Therefore, when the wind speed is high, sampling only at the planned sampling points will cause large errors. Therefore, in Example 1 of the present invention, after the wind force reaches a certain level, in addition to sampling at the preset sampling point, secondary sampling can be performed at a certain distance downstream of the airflow, which can effectively ensure that the subsequent sampling analysis results are more accurate.

[0044] In general, multiple sampling is required at the sampling points. The present invention can be performed in the following manner for sampling at the preset sampling points and secondary sampling at a certain distance downstream of the airflow: that is, multiple sampling is performed in at least three directions with the sampling point as the center and the second preset distance as the radius. For example: after the drone arrives at the preset sampling point, when the actual wind speed is lower than the wind speed threshold, sampling can be performed only at the sampling point without secondary sampling. Sampling only at the sampling point includes sampling in situ, and then cruising by the drone, moving to a preset distance (for example, a distance of 1 to 3 meters) in the four directions of east, west, south and north with the sampling point as the center, and then hovering, sampling is performed at these four adjacent points respectively, and in the subsequent sampling analysis, the sampling data of the preset sampling point can be calculated by weighted averaging the sampling data of the five points. The secondary sampling performed when the actual wind speed is higher than the wind speed threshold can also be performed in the above manner. The present invention adopts the preset point and the points adjacent to the preset point for multi-frequency sampling, which can further improve the accuracy of sampling and subsequent analysis in a complex airflow environment.

[0045] The control process of executing sampling at each specific point is as follows: the drone starts to fly to the sampling point, and the status of the corresponding sampling task is displayed as sampling. After arriving at the sampling point, the drone hovers, the electric valve of the sampling container opens, and the sampling control module records the exact time when the valve opens. After the set sampling time is reached, the electric valve closes, and the sampling control module records the exact time when the valve closes. After the sampling is completed, the drone flies back with the sampling equipment, and the sampling control module transmits the recorded information back to the control system, including identifying the exact time when the valve opens as the sampling start time and the exact time when the valve closes as the sampling end time. Then the status of the corresponding sampling task is displayed as sampling completed. If one or more sampling tasks in the plan cannot be completed as planned due to various factors, the status of the sampling task is displayed as sampling interruption, and the status of the entire sampling plan is displayed as incomplete. After reallocating the sampling equipment, you can select the sampling task with the status of sampling interruption separately and run the sampling plan again. Until the status of all sampling tasks in a sampling plan is sampling completed, the status of the plan is displayed as running completed.

[0046] Example 2

[0047] like Figure 2 As shown, the embodiment 2 of the atmospheric sampling control method of the present invention adds a wind direction detection step on the basis of the embodiment 1. That is, when it is determined that the actual wind speed at the sampling point is higher than the wind speed threshold, the wind direction detection is performed, and after the wind direction is determined in real time, the drone can be driven to fly downstream of the wind direction for the aforementioned first preset distance with the assistance of the drone cruise system and then hover, and secondary sampling is performed after hovering.

[0048] Example 3

[0049] like Figure 3 As shown, the atmospheric sampling control device of the present invention is used for atmospheric sampling of unmanned aerial vehicles, and includes: a task establishment module 10 and a wind speed judgment module 20. The task establishment module 10 is used to establish one or more sampling tasks, determine sampling points, sampling information, and establish an association between sampling tasks and sampling equipment; the wind speed judgment module 20 can compare the real-time wind speed of the detected sampling point with the wind speed threshold after the unmanned aerial vehicle arrives at the preset sampling point: when the wind speed of the sampling point is detected to be lower than the wind speed threshold, the sampling equipment performs sampling at the preset sampling point according to the preset sampling information; when the wind speed of the sampling point is detected to be higher than the wind speed threshold, the sampling equipment performs secondary sampling at a first preset distance downstream of the airflow after sampling at the preset sampling point.

[0050] Further Figure 3 As shown, the atmospheric sampling control device of the present invention may further include a wind direction detection module 30. The wind direction detection module 30 is used to detect the wind direction when the wind speed at the sampling point is higher than the wind speed threshold, and send the wind direction information to the UAV flight controller to control the UAV to fly downstream of the wind direction for a first preset distance and then hover, and perform secondary sampling after hovering.

[0051] Further Figure 3 As shown, the atmospheric sampling control device of the present invention further includes a sampling control module 40, which specifically includes: a multi-point execution submodule 41, an information recording submodule 42, an information identification submodule 43 and a status display submodule 44. Among them, the multi-point execution submodule 41 is used to control multiple sampling in at least three directions with the sampling point as the center and the second preset distance as the radius; the information recording submodule 42 is used to record the opening and closing time information of the electric valve of the sampling container; the information identification submodule 43 is used to transmit the recorded information back to the ground control system, and identify the opening time of the electric valve as the sampling start time and the closing time of the electric valve as the sampling end time; the status display submodule 44 can display the sampling status according to the information integrity of the sampling start time and end time.
