[0019] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0020] See also Figure 1 As shown, an embodiment of the present invention provides a protective device for detecting harsh environments, the device comprising a protective shell, a suspension rope, a soft fixing device and a controller; the suspension rope is arranged at the inner top of the protective shell, the top of the air quality monitoring instrument is connected to the hook below the suspension rope, and the controller is communicatively connected to the air quality monitoring instrument; the soft fixing device is arranged inside the protective shell, and is used to adjust the fixing tightness of the air quality monitoring instrument suspended on the suspension rope based on the control instructions of the controller.

[0021] The present invention constructs a protective device for detecting harsh environments of the above structure. When in use, the user places the air quality monitoring instrument in the protective shell and hangs it on a hook below the suspension cable (preferably with a closed lock). The controller is communicated with the air quality monitoring instrument to obtain detection data of the air quality monitoring instrument. Based on the detection data, control instructions for the soft fixing device can be generated to enable the soft fixing device to adjust the tightness of the air quality monitoring instrument suspended on the suspension cable, thereby ensuring that when the harsh environment changes, the air quality monitoring instrument can still maintain good stability and avoid excessive shaking and collision damage with the inner wall of the protective shell.

[0022] It can be seen that, on the one hand, the above-mentioned protection device of the present invention can realize soft constraints on the air quality monitoring instrument, and avoid the collision and damage between the air quality monitoring instrument and the inner wall of the protective shell when the protective shell shakes in a harsh environment, thereby achieving the effect of reducing the probability of damage. On the other hand, the above-mentioned protection device of the present invention adopts a soft fixing device, and the soft fixing device can be adapted to air quality monitoring instruments with various shell shapes, and can be adapted to air quality monitoring instruments of different types and models, thereby realizing the protection of air quality monitoring instruments that are not equipped with a specially designed protective shell.

[0023] Furthermore, the soft fixing device includes two first fixed wheels, two second fixed wheels, two first movable wheels, two second movable wheels, and two slide grooves; each of the first fixed wheels is symmetrically arranged above the protective shell near the top, and each of the second fixed wheels is symmetrically arranged below the protective shell near the bottom; each of the first movable wheels is symmetrically arranged above the middle of the protective shell, and each of the second movable wheels is symmetrically arranged below the middle of the protective shell; and each of the first movable wheels and each of the second movable wheels are respectively slidably arranged in the slide grooves, and each of the first movable wheels and each of the second movable wheels are configured with an electric drive mechanism controlled by the controller; an elastic fixing belt is connected between each of the first fixed wheels and the second movable wheel on the opposite side, and an elastic fixing belt is connected between each of the second fixed wheels and the first movable wheel on the opposite side, and the inner intersection area of ​​the four elastic fixing belts forms an accommodating space, and the air quality monitoring instrument is suspended in the accommodating space.

[0024] In this embodiment, continue to refer to Figure 1As shown, the soft fixing device of the present invention is composed of a pair of first fixed wheels, a pair of second fixed wheels, a pair of first moving wheels, a pair of second moving wheels, and a pair of slide grooves. The protective shell is divided into a left area and a right area based on the center line of the protective shell. From top to bottom, a first fixed wheel is arranged at the top inner part of the left area, a first moving wheel is arranged above the middle outer part, a second moving wheel is arranged below the middle outer part, and a second fixed wheel is arranged at the bottom inner part. The right area is symmetrically arranged with the left area. Elastic fixing belts are arranged between the first fixed wheel and the second moving wheel, and between the second fixed wheel and the first moving wheel at diagonally opposite corners of the left and right areas. In this way, the four elastic fixing belts cross each other in pairs, and the inner crossing area forms an accommodating space, and the air quality monitoring instrument is suspended in the accommodating space. The four elastic fixing belts contact the surface contour of the air quality monitoring instrument, thereby realizing the restraint and fixation of the air quality monitoring instrument.

[0025] In addition, each group of first moving wheels and second moving wheels are arranged in the slide slot up and down respectively, and can realize up and down movement in the slide slot through the electric drive mechanism configured respectively, and the electric drive mechanism is controlled by the above-mentioned controller. The slide slot can be divided into two unconnected upper and lower parts for the first moving wheel and the second moving wheel to use respectively; or it can be a whole connected form without division for the first moving wheel and the second moving wheel to use together. The present invention does not make specific limitations on this.

[0026] Furthermore, the controller is used to implement the following method steps: receiving air quality data detected by an air quality monitoring instrument; if the air quality data includes wind speed data, determining a first tightness based on the wind speed data and a first preset comparison table; if the air quality data does not include wind speed data, parsing a monitoring video image from the air quality data, extracting image fluctuation data from the monitoring video image, predicting swing amplitude data of the protective device based on the image fluctuation data, and determining a second tightness based on the swing amplitude data and a second preset comparison table; generating a corresponding control instruction based on the first tightness or the second tightness, and performing position control on each of the first moving wheels and each of the second moving wheels based on the control instruction to adjust the tightness of the soft fixing device fixing the air quality monitoring instrument suspended on the suspension cable.

[0027] In this embodiment, the present invention is designed to use an elastic fixing belt to surround the housing of the air quality monitoring instrument, so as to achieve the purpose of fixing and restraining it, but the surrounding of the elastic fixing belt will reduce the heat dissipation performance of the air quality monitoring instrument, and in severe cases, it may cause the internal temperature of the air quality monitoring instrument to be too high and unable to work. In response to this technical problem, the present invention sets a controller to decide which tightness to use according to the air quality data detected by the air quality monitoring instrument, that is, by adjusting the tightness, it is achieved that the purpose of fixing and restraining is achieved while reducing the heat dissipation effect on the air quality monitoring instrument.

[0028] Specifically, the air quality monitoring instrument transmits the detected air quality data to the controller in real time, and the controller analyzes the air quality data. When used for wind measurement, a monitoring camera and a three-dimensional laser wind measurement radar will be deployed in the air quality monitoring instrument. The monitoring camera can capture monitoring video images of the area in which it is located, while the three-dimensional laser wind measurement radar directly uses the Doppler effect principle to measure the wind speed data. The magnitude of the wind speed will directly cause the protective device to have different degrees of shaking amplitude. Therefore, the critical value of the tightness that can prevent the air quality monitoring instrument from colliding with the inner wall of the protective shell, that is, the first tightness, can be measured at different wind speeds, and then a first preset comparison table is established. The first preset comparison table contains multiple groups of comparison relationships between different wind speeds and the first tightness.

[0029] However, the three-dimensional laser wind radar may not transmit wind speed data to the controller due to periodic self-calibration, failure, etc., resulting in the controller being unable to parse the wind speed data, and being unable to determine the appropriate first tightness by comparing with the first preset comparison table. In response to this, the controller further obtains the monitoring video image taken by the monitoring camera, from which the image fluctuation data can be extracted, and the swing amplitude data of the protective device can be predicted based on the image fluctuation data, and the second tightness can also be determined based on the swing amplitude data and the second preset comparison table. The second preset comparison table is established in the same way as the first preset comparison table, specifically: the tightness critical value that can prevent the air quality monitoring instrument from colliding with the inner wall of the protective shell under different swing amplitudes, that is, the first tightness, is measured, and then a second preset comparison table is established, and the second preset comparison table contains multiple groups of comparison relationships between different swing amplitudes and the second tightness.

[0030] Therefore, this embodiment of the present invention realizes that regardless of whether the air quality monitoring instrument directly measures the wind speed data, it is possible to determine the appropriate tightness to control the soft fixing device to adjust the fixing tightness of the air quality monitoring instrument suspended on the suspension cable, thereby achieving the technical effects of fixed constraint and reducing the degree of heat dissipation impact at the same time.

[0031] It should be noted that the image fluctuation data can be determined based on the position changes of several reference points in the surveillance video image, and the swing amplitude data can be determined by using the conversion relationship between the image data and the real world data.

[0032] Furthermore, the position of each of the first moving wheels and each of the second moving wheels is controlled based on the control instruction to adjust the tightness of the air quality monitoring instrument suspended on the suspension cable by the soft fixing device, including: determining a first target position of the first moving wheel and a second target position of the second moving wheel based on the first tightness or the second tightness included in the control instruction; controlling each of the first moving wheels to move to the first target position, and controlling each of the second moving wheels to move to the second target position, to adjust the tightness of the air quality monitoring instrument suspended on the suspension cable by the soft fixing device.

[0033] In this embodiment, the first movable wheel and the second movable wheel in the present invention can change their positions arbitrarily in the slide groove under the drive of the electric drive mechanism, and different positions will directly affect the distance between the fixed wheel on the opposite side. Since the preset length of the elastic fixing belt between the corresponding fixed wheel and the movable wheel is fixed (but the length can be changed under the action of tension), the binding force of the elastic fixing belt on the air quality monitoring instrument will be different, thereby achieving the purpose of strengthening the fixation of the air quality monitoring instrument and weakening the fixation.

[0034] Further, the controlling of each of the first moving wheels to move to the first target position, and the controlling of each of the second moving wheels to move to the second target position, includes: if the first tightness or the second tightness is an increased tightness compared to the currently executed tightness, controlling each of the first moving wheels to move to the first target position, and each of the second moving wheels to move to the second target position at a first moving speed; if the first tightness or the second tightness is a decreased tightness compared to the currently executed tightness, controlling each of the first moving wheels to move to the first target position, and each of the second moving wheels to move to the second target position at a second moving speed; wherein the first moving speed is higher than the second moving speed.

[0035] In this embodiment, the tightness adjustment of the air quality monitoring instrument includes two situations: tightening and loosening. In the tightening situation, each moving wheel can be controlled to be adjusted at a faster first moving speed, that is, the first moving wheel moves upward quickly and the second moving wheel moves downward quickly, so that the response speed to the shaking caused by the harsh environment can be improved. In the loosening situation, each moving wheel can be controlled to be adjusted at a slower second moving speed, that is, the first moving wheel moves slowly downward and the second moving wheel moves slowly upward, so that the shaking amplitude when the tightness changes from tight to loose can be reduced, and the collision between the air quality monitoring instrument and the protective shell caused by too fast loosening can be avoided.

[0036] It should be noted that the moving wheels on the left and right sides should move synchronously, at least the two first moving wheels on the left and right sides move synchronously, and / or the two second moving wheels on the left and right sides move synchronously.

[0037] Furthermore, the controller is also used to: when receiving a start signal, control each of the first moving wheels to move from a first initial position to a third target position according to the start signal, and control each of the second moving wheels to move from a second initial position to a fourth target position.

[0038] In this embodiment, when no air quality monitoring instrument is placed in the protective shell, the moving wheels return to their respective initial positions, and at this time, each elastic fixing belt is loose. After the air quality monitoring instrument is placed on the suspension rope, the corresponding optional tightness button is selected on the protective shell according to the size of the air quality monitoring instrument, and the controller receives a start signal, and controls each first moving wheel to move from the first initial position to the third target position, and controls each second moving wheel to move from the second initial position to the fourth target position according to the start signal, thereby realizing the initial restraint and fixation of the air quality monitoring instrument.

[0039] The preset length of the elastic fixing belt between the fixed wheel and the movable wheel is adjustable. Specifically, a longer elastic fixing belt is wound around the fixed wheel, and a section of the elastic fixing belt can be released by rotating the fixed wheel, thereby changing the preset length. Of course, the elastic fixing belt can also be wound up by controlling the movable wheel to rotate or the fixed wheel to reverse, thereby shortening the preset length.
