Description

TECHNICAL FIELD

[0001] The present application relates to the field of road disease detection equipment, in particular to a detection vehicle industrial camera system protection device and method. BACKGROUND

[0002] Road disease detection based on machine vision is the main technology of current road intelligent detection. One of the core contents of this technology is to collect high-quality road disease images. The equipment used is an industrial camera installed on the top of the detection vehicle. Because the camera is exposed to the air for a long time, and the camera is directly exposed to the wind when driving at high speed, the camera lens is often blurred by factors such as insect collision, rain, snow and dust, which affects the image quality of the camera, which is a problem that needs to be solved urgently.

[0003] Currently, industrial camera protective shells are mainly divided into two types. One is a professional monitoring industrial camera protective shell that can protect the internal precision electronic components and single-lens reflex lens from the influence of the climate environment, but it does not have a self-cleaning function and can only be used in static conditions. A kind of industrial camera protection device with self-cleaning function is disclosed in Chinese patent (publication number: CN 113534573 B), which can cool the industrial camera to ensure its normal operation, and at the same time, the inner cavity of the shell can always be in a positive pressure state, so that external air and dust cannot enter the inner cavity of the shell, thereby achieving good sealing effect, and through the design of the cleaning mechanism, the self-cleaning of the window glass and the brush is realized. Such industrial camera protective shells are provided with cleaning motors, wipers, spray head assemblies for spraying the camera window, like the wiper assemblies of cars. The cleaning process needs to be used with cleaning agents, water, etc., and the cleaning cycle is also relatively short. If it is placed on the roof for cleaning, the interference of the wiper will block the shooting of the industrial camera, affecting the recognition accuracy, and it needs to be parked on the side to clean, and frequent parking on the side at high speed will also bring great safety hazards to traffic. At present, the protective shell suitable for static environment and the protective shell using wiper cannot solve the existing problems, and it is difficult to realize flexible cleaning and cannot guarantee to reduce the influence on the normal work of the industrial camera during the cleaning process.

DETAILED DESCRIPTION

[0036] Embodiment 1

[0037] In a typical embodiment of the application, as shown in Figures 1-7 A detection vehicle industrial camera system protection device is given.

[0038] At present, neither the protective shell suitable for static environment nor the protective shell using the wiper type can solve the existing problems, and it is difficult to achieve long-term cleaning, and the normal work of the industrial camera cannot be affected during the cleaning process. Based on this, the embodiment provides a detection vehicle industrial camera system protection device, which adopts a streamlined protective shell based on fluid mechanics as the protective structure of the industrial camera system, the windward shell 1 and the leeward shell 2 of the protective shell can move relative to each other to form a dynamic streamlined wind guide structure, change the wind angle of the windward shell 1, and form a high pressure area on the leeward upper convex surface 5 and the leeward lower convex surface 6 of the leeward shell 2 at different vehicle speeds, so as to carry away the pollutants carried by the airflow and avoid adhesion, keep the leeward upper convex surface 5 and the leeward lower convex surface 6 as the perspective surface of the industrial camera system clean, reduce the shooting obstruction to improve the shooting accuracy.

[0039] As shown in Figure 1As shown, the protective device for the industrial camera system of the inspection vehicle includes a protective shell, an adjustment component 11, a controller 12, and a wind speed sensor 8. The protective shell includes a windward shell 1 and a leeward shell 2, each with an opening. One end of the opening of the leeward shell 2 extends into the opening of the windward shell 1. The end of the windward shell 1 away from the opening forms a windward upper convex surface 3 and a windward lower convex surface 4, and the end of the leeward shell 2 away from the opening forms a leeward upper convex surface 5 and a leeward lower convex surface 6, which serve as the transmission surface of the industrial camera system.

[0040] Among them, the windward upper convex surface 3 and the windward lower convex surface 4 need to be made of materials with strong toughness, such as nickel-based alloys or rigid PVC plastic, to resist airflow and maintain the stability of the windward shell 1. The leeward upper convex surface 5 and the leeward lower convex surface 6 are the image acquisition surfaces of the industrial camera, and need to be made of transparent materials to achieve clear shooting. It is recommended to use high-definition transparent PVC plastic and other materials.

[0041] like Figure 3 As shown, the four parts—windward convex surface 3, windward lower convex surface 4, leeward upper convex surface 5, and leeward lower convex surface 6—are all irregularly shaped, gradually changing curved surfaces, with their trajectories corresponding to gradual curves. Based on fluid dynamics formulas, the streamlined self-cleaning function can be achieved according to the following design requirements: In the forward-backward direction of the testing vehicle, the windward upper convex surface 3 is set with an outer diameter of A mm, an inner diameter of 0.605 A mm, and an arc height of 0.233 A mm. The windward lower convex surface 4 is required to have an outer diameter of A mm, an inner diameter of 0.558 A mm, and an arc height of 0.326 A mm. The leeward upper convex surface 5 is required to have an outer diameter of 1.325 A mm, an inner diameter of 0.953 A mm, and an arc height of 0.279 A mm. The leeward convex surface 6 is required to have an outer diameter of 1.209Amm, an inner diameter of 1.325Amm, and an arc height of 0.186Amm; the common plane at the front is 0.081Amm higher than the common plane at the rear; the overlap between the windward upper convex surface 3 and the leeward upper convex surface 5 is 0.465Amm, and the overlap between the windward lower convex surface 4 and the leeward lower convex surface 6 is 0.372Amm.

[0042] The intersection line of the windward upper convex surface 3 and the windward lower convex surface 4 is parallel to the intersection line of the leeward upper convex surface 5 and the leeward lower convex surface 6. The plane containing the two intersection lines is used as the reference plane. The windward upper convex surface 3 and the leeward upper convex surface 5 are located above the reference plane, and the windward lower convex surface 4 and the leeward lower convex surface 6 are located below the reference plane. The windward upper convex surface 3 and the windward lower convex surface 4 are both curved surfaces. The adjusting component 11 causes the windward housing 1 to deform in order to adjust the curvature of the windward upper convex surface 3 and the windward lower convex surface 4.

[0043] In addition, such as Figure 4As shown, in the width direction of the testing vehicle, the outer diameter of both the windward upper convex surface 3 and the windward lower convex surface 4 is 0.744Amm; the outer diameter of both the leeward upper convex surface 5 and the leeward lower convex surface 6 is 0.724Amm. It is ensured that the windward upper convex surface 3 and the windward lower convex surface 4 can overlap, and that the leeward upper convex surface 5 and the leeward lower convex surface 6 can overlap.

[0044] The protective shell must be resistant to deformation. When the test vehicle is in motion, the material used for the windward shell 1 at the front of the vehicle must meet the requirements for compressive strength and deformation resistance, while the material used for the leeward shell 2 at the rear of the vehicle must meet the requirements for tensile strength and deformation resistance, and the requirements must not be less than the values ​​shown in Table 1.

[0045] Table 1 Strength Requirements

[0046] Vehicle speed (km / h) 80 90 100 110 120 Windward shell compression strength (KPa) 1.0 1.2 1.5 1.8 2.0 Leeward shell tensile strength (KPa) 0.8 0.9 1.0 1.1 1.2

[0047] like Figure 2 and Figure 5 As shown, sealing elements are provided between the opening of the leeward housing 2 and the opening of the windward housing 1, between the windward upper convex surface 3 and the leeward upper convex surface 5, and between the windward lower convex surface 4 and the leeward lower convex surface 6, respectively, forming a protective cavity inside the protective housing that is isolated from the outside. The sealing element between the windward upper convex surface 3 and the leeward upper convex surface 5 is an upper seal 10, and the sealing element between the windward lower convex surface 4 and the leeward lower convex surface 6 is a lower seal 9. Both the upper seal 10 and the lower seal 9 are elastic sealing structures.

[0048] The elastic sealing structure uses waterproof sealing material and is bonded to both the leeward shell 2 and the windward shell 1. Vertically, the cross-sectional height of the front windward shell 1 is greater than that of the rear leeward shell 2. The waterproof sealing material can be a soft sponge, adhesively bonded between the openings of the leeward shell 2 and the windward shell 1, exhibiting good elasticity. When the gap between the windward shell 1 and the leeward shell 2 changes, the elastic sealing structure itself can extend or compress effectively, providing waterproofing and insulation, and significantly extending the equipment's service life.

[0049] like Figure 5 As shown, the protective shell 2 is connected to a support 7, and the wind speed sensor 8 is mounted on the support 7. The support 7 mainly serves to fix the protective shell to the roof of the inspection vehicle. It is made of materials with strong impact resistance, such as nickel-based alloys, and is equipped with a cushioning pad at the bottom to reduce slippage when used on the vehicle roof. The protective shell forms a protective cavity, and a bracket 13 for supporting the industrial camera system is installed inside the protective cavity. The bracket 13 can be moved and adjusted relative to the protective shell, such as... Figure 3 and Figure 4As shown, the size of the bracket 13 can be adjusted in length and width within the range of 0.465Amm in width and 0.372Amm in height, so as to be suitable for the size of various industrial camera systems, facilitate the installation of components of the industrial camera system, and meet the installation requirements.

[0050] The adjusting assembly 11 comprises a driving member 17 and a rotating shaft 14, one end of the rotating shaft 14 is connected to the driving member 17, the other end passes through the back shell 2 and is connected to the front shell 1 as a fixed end 16, the rotating shaft 14 passes through the back shell 2 and is matched with a rotating seat 15, the driving member 17 drives the rotating shaft 14 to rotate relative to the back shell 2, so as to drive the front shell 1 to deform and move.

[0051] The fixed end 16 is connected to the front shell 1 and limits the dislocation movement of the front shell 1, the diameter of the fixed end 16 is 0.1Amm, and the thickness is not limited. The inside of the fixed end 16 is provided with a non-slip pad, the driving member 17 is output through the rotating shaft 14 on both sides, and the total thickness of the non-slip pads of the fixed ends 16 at the ends of the two rotating shafts 14 does not exceed 0.015Amm. The rotating shaft 14 is made of a torsion-resistant alloy material with a diameter of 0.08Amm. The diameter of the driving member 17 is within 0.7Amm, and the lengths of the rotating shafts 14 on both sides of the driving member 17 are adjusted according to requirements. The entire adjusting assembly 11 can be smoothly placed in the protective shell.

[0052] As shown in Figure 5 and Figure 6 , the front shell 1 and the back shell 2 are connected by using an adjusting member when assembled, the rotating seat 15 is positioned by using a bearing, the rotating shaft 14 passes through the inner ring of the bearing and is fixed with the inner ring of the bearing, so as to limit the dislocation phenomenon of the front shell 1 and the back shell 2. The driving member 17 is an electric motor, a linear motor, a servo motor, etc., and is controlled to rotate at a speed of not less than 600r / min to drive the rotating shaft 14 to rotate in time, so as to change the wind angle of the front shell 1, adjust the wind field state of the entire protective shell, and prevent dust from gathering, as shown in Figure 6 .

[0053] The wind speed sensor 8 can measure the wind speed in real time and transmit the data to the controller 12, and the controller 12 can be connected to a computing comprehensive processing system. According to the wind speed, the required angle is calculated, and the work of the driving member 17 is controlled to dynamically adjust the wind angle of the streamlined protective shell. The adjusting assembly 11 is installed in the protective shell and connected to the front shell 1 and the back shell 2, respectively, and the adjusting assembly 11 can drive the front shell 1 to deform and change the orientation thereof relative to the back shell 2.

[0054] The controller 12 is connected with the adjusting assembly 11 and the wind speed sensor 8 outside the protective shell, the wind speed sensor 8 obtains the wind speed of the wind field where the protective shell is located and sends to the controller 12, the controller 12 controls the adjusting assembly 11 to make the leeward upper convex surface 5 and the leeward lower convex surface 6 of the protective shell be in the high pressure area of the wind field.

[0055] Embodiment 2

[0056] In another typical embodiment of the present application, as shown in Figures 1-7 a working method of the detection vehicle industrial camera system protection device is given, which utilizes the detection vehicle industrial camera system protection device in embodiment 1.

[0057] A working method of the detection vehicle industrial camera system protection device, comprising:

[0058] The protective shell is installed on the detection vehicle, and the windward shell body 1 is located at the windward end of the detection vehicle;

[0059] When the detection vehicle is running, the wind speed sensor 8 measures the wind speed of the wind field where the protective shell is located, the controller 12 calculates the required angle of the windward shell body 1 when the leeward upper convex surface 5 and the leeward lower convex surface 6 are in the high pressure area of the wind field under this wind speed, and controls the adjusting assembly 11 to drive the windward shell body 1 to move;

[0060] The windward shell body 1 is adjusted to the state of the windward shell body 1 when the airflow is in the high pressure area of the wind field at the leeward upper convex surface 5 and the leeward lower convex surface 6, the wind speed of the wind field is measured in real time, and the windward shell body 1 is adjusted;

[0061] The industrial camera system can obtain the image of the road surface where the detection vehicle runs through the leeward upper convex surface 5 and the leeward lower convex surface 6.

[0062] When the adjusting assembly 11 drives the windward shell body 1 to move, the windward shell body 1 is deformed and the orientation of the windward shell body 1 relative to the leeward shell body 2 is changed, and the airflow in the wind field is guided.

[0063] As shown in Figures 1-6 When the vehicle runs at high speed, the airflow passing through the streamlined protective shell at high speed will form a high pressure area at the tail end of the protective shell, which has a positive pressure compared with other areas, generating a force to push away the dust and other pollutants brought by the wind to achieve a self-cleaning function.

[0064] When the wind speed changes or the vehicle speed changes, the surface of the streamlined protective shell cannot form a high pressure area, and a viscous flow will be formed to attach dust to the surface of the protective shell. The wind speed sensor 8 measures the wind speed parameter and transmits the specific parameters obtained to the controller 12, and the controller 12 calculates the required angle. Then control the adjusting assembly 11 to work, and the windward shell body 1 moves relative to the leeward shell body 2 to adjust the angle of the front shell body. As shown in Figure 6As shown, after the angle is changed, the wind speed can linearly pass through the streamlined protective shell, and a high pressure area reappears to generate positive pressure, ensuring that the upper leeward convex surface 5 and the lower leeward convex surface 6 do not appear to be sticky.

[0065] For example, an industrial camera for detecting the roof of a vehicle is used, the widest part of the detection vehicle industrial camera system protection device is 165 mm, and the height is 155 mm, which is used at a speed of 80 km / h to 100 km / h.

[0066] According to the above calculation formula, the outer diameter of the upper windward convex surface 3 is 430 mm, the inner diameter is 260 mm, and the arc height is 100 mm. The outer diameter of the lower windward convex surface 4 is required to be 430 mm, the inner diameter is 240 mm, and the arc height is 140 mm. The outer diameter of the upper leeward convex surface 5 is required to be 570 mm, the inner diameter is 410 mm, and the arc height is 120 mm. The outer diameter of the lower leeward convex surface 6 is required to be 520 mm, the inner diameter is 370 mm, and the arc height is 80 mm; the common plane of the front part is 35 mm higher than that of the rear part; the overlap between the upper windward convex surface 3 and the upper leeward convex surface 5 is 200 mm, and the overlap between the lower windward convex surface 4 and the rear lower surface is 160 mm.

[0067] The outer diameter of the upper windward convex surface 3 and the lower windward convex surface 4 is 320 mm; the outer diameter of the upper leeward convex surface 5 and the lower leeward convex surface 6 is 311.3 mm.

[0068] The fixed end 16 is made of aluminum alloy material with a diameter of 43 mm and a thickness of 5 mm. There is a non-slip pad on the inside of the fixed end 16, and the thickness of the non-slip pad is 3.2 mm. The rotating shaft 14 is made of torsion-resistant alloy material with a diameter of 34.4 mm. The driving member 17 uses a linear motor, which requires a speed of not less than 600 r / min to control the rotation of the rotating shaft 14.

[0069] The overall diameter of the driving member 17 is 172 mm, and the length of the rotating shaft 14 on both sides of the driving member 17 is adjusted according to requirements.

[0070] According to the selection of the shell material and the design of the thickness according to the speed of the vehicle, in this embodiment, the windward shell 1 is made of PVC hard plastic with a thickness of 5 mm, and the leeward shell 2 is made of PVC transparent plastic with a thickness of 3 mm. The windward shell 1 is designed with outward tension, and the leeward shell 2 is designed with inward tension. When assembled, since the windward shell 1 and the leeward shell 2 have tension when designed, they can be well combined together, and the stability of the shell is also greatly enhanced due to the limiting action of the adjusting assembly 11. The curved shell of the upper windward convex surface 3 and the curved shell of the lower windward convex surface 4 are connected by welding, and the curved shell of the upper leeward convex surface 5 and the curved shell of the lower leeward convex surface 6 are connected by gluing.

[0071] Through the aerodynamic theory, the formula is introduced into the controller 12. The controller 12, the adjusting assembly 11 and the support 13 are placed inside the protective shell and assembled (the camera is towards the back), then the windward shell 1 and the leeward shell 2 are connected together, finally the support 7 is installed, and the wind speed sensor 8 is installed.

[0072] According to the installation position of the vehicle, the angle of the protective shell installation is determined. According to the wind direction of the installation, the basic parameters are determined, the wind speed sensor 8 is connected to the controller 12, and the basic parameters are input into the controller 12.
