The data collection and transmission of cars during driving are related to the degree of driving safety.

[0060] However, if the internal parts of the existing data acquisition equipment are damaged before or after use, the prediction of the surroundings will be inaccurate, so it needs to be disassembled regularly for cleaning and maintenance. However, it is not convenient to disassemble the internal parts of the shell in the prior art, and the disassembly process also requires the use of corresponding tools to remove the internal parts, which will cause inconvenience during maintenance.

[0061] Based on the above problems, the present application provides a vehicle-mounted data acquisition device and a vehicle-mounted data acquisition method. The key points of the invention are that the acquisition piece is detachably mounted on an installation and disassembly plate, and the installation and disassembly plate can be taken in and placed in the shell with the help of an operating port on the shell. When the installation and disassembly plate with the acquisition piece is placed in the shell, it can be positioned inside the shell by a positioning assembly, so that the data acquisition unit of the acquisition piece can collect external data through the acquisition hole. When the acquisition piece needs to be disassembled for maintenance, it is only necessary to open the opening and closing door and release the positioning of the installation and disassembly plate by the positioning assembly, so that the installation and disassembly plate together with the acquisition piece can be taken out of the shell. Finally, the acquisition piece can be separated from the installation and disassembly plate to realize inspection or maintenance of the acquisition piece, which solves the technical problem in the related art that the acquisition equipment is difficult to disassemble conveniently and quickly when it needs maintenance.

[0062] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0063] In a first aspect, an embodiment of the present application provides a vehicle-mounted data collection method.

[0064] In one embodiment, referring to Figure 1 , Figure 1 The vehicle-mounted data acquisition device provided for this application includes:

[0065] The housing 1 comprises a first side wall 10 and a second side wall 11. The first side wall 10 is provided with a collection hole 100. The second side wall 11 is provided with an operation port, and the operation port is provided with an opening and closing door 110.

[0066] An installation and removal plate 2 is placed inside the housing 1, and is movably arranged inside the housing 1 and parallel to the first side wall 10. The installation and removal plate 2 is taken in and out of the housing 1 through the operation port;

[0067] A collecting member 3, which is detachably mounted on a side of the mounting and disassembly plate 2 facing the first side wall 10, and includes a data collecting unit 30 for collecting external information through the collecting hole 100;

[0068] The positioning assembly 4 is disposed inside the housing 1 to position / release the mounting and disassembly plate 2 in the vertical direction of the first side wall 10 .

[0069] Specifically, the shell 1 is a rectangular parallelepiped structure, and the first side wall 10 and the second side wall 11 are two side walls perpendicular to each other, and in this embodiment, the two side walls parallel to the first side wall 10 are both the second side walls 11, that is, an operation port and an opening and closing door 110 are provided on both sides of the first side wall 10, so that the shell 1 can be opened from two directions. In this embodiment, the opening and closing door 110 is specifically hingedly installed on the operation port to realize rotation opening and closing. The installation of the collection part 3 on the installation and disassembly plate 2 is adaptively set according to the specific structure of the collection part 3, and finally the collection part 3 and the installation and disassembly plate 2 can be detachably connected. It should be noted that after the collection part 3 is installed on the installation and disassembly plate 2, it does not affect the taking and placing in the shell 1.

[0070] In the present embodiment, the collecting piece 3 is detachably mounted on the mounting and disassembly plate 2, and the mounting and disassembly plate 2 can be taken in and out of the shell 1 with the aid of the operating port on the shell 1. When the mounting and disassembly plate 2 equipped with the collecting piece 3 is placed in the shell 1, it can be positioned inside the shell 1 by the positioning component 4, so that the data collecting unit 30 of the collecting piece 3 can collect external data through the collecting hole 100. When the collecting piece 3 needs to be disassembled for maintenance, it is only necessary to open the opening and closing door 110, release the positioning of the mounting and disassembly plate 2 by the positioning component 4, and then the mounting and disassembly plate 2 together with the collecting piece 3 can be taken out of the shell 1. Finally, the collecting piece 3 can be separated from the mounting and disassembly plate 2 to realize the inspection or maintenance of the collecting piece 3, thereby solving the technical problem in the related art that the collecting equipment is difficult to disassemble conveniently and quickly when it needs maintenance.

[0071] Reference Figure 2 and Figure 3 , further, in one embodiment, the positioning component 4 includes:

[0072] at least one spring 40, the compression direction of which is vertical to the first side wall 10, and one end of which is fixedly connected to the housing 1;

[0073] An extrusion rod 41 is connected to the other end of the spring 40 and extends vertically along the first side wall 10, and

[0074] The spring 40 and the squeezing rod 41 are located on a side of the mounting and disassembling plate 2 away from the collecting hole 100 , so as to press and position the mounting and disassembling plate 2 in the vertical direction of the first side wall 10 .

[0075] Specifically, the shell 1 has two third side walls perpendicular to the first side wall 10 and the second side walls 11 in addition to the first side wall 10 and the second side walls 11. In this embodiment, there are two springs 40, which are fixedly mounted on the inner walls of the third side walls, and the expansion and contraction direction is perpendicular to the first side wall 10. In this arrangement, the spring 40 will not cause too much obstruction to the operation port, and can elastically squeeze the extrusion rod 41 connected to one end thereof. After the installation and disassembly plate 2 is placed in the shell 1, it can be pressed and positioned under the action of the extrusion rod 41 driven by the two springs 40. At this time, after the collection piece 3 on the installation and disassembly plate 2 is positioned, the data collection unit 30 therein can collect external data through the collection hole 100.

[0076] Furthermore, in some embodiments, the extrusion rod 41 is provided with a block 42 at one end away from the spring 40, the mounting and disassembly plate 2 is provided with a slot 20 corresponding to the block 42, and an operating rod 43 is provided on one side of the extrusion rod 41 close to the central area of ​​the shell 1.

[0077] In this embodiment, through the matching relationship between the block 42 and the slot 20, the installation and disassembly plate 2 can be more quickly positioned to a suitable position when it is placed in the housing 1 for fixing, that is, the configuration position of the block 42 and the slot 20. In this position, the data acquisition unit 30 on the acquisition component 3 can collect external information with the help of the acquisition hole 100. At the same time, the operating rod 43 set on one side of the squeezing rod 41 will also facilitate the operator to move the squeezing rod 41, that is, to pull the squeezing rod 41 to make the block 42 disengage from the slot 20, and then contact the installation and disassembly plate 2. In addition, the operating rod 43 is L-shaped in this embodiment, one end of which is connected to the squeezing rod 41, and the other end extends to fit the installation acquisition plate.

[0078] Reference Figure 1 and Figure 4 , further, in one embodiment, the vehicle-mounted data acquisition device further includes:

[0079] Connecting base 5;

[0080] An adjusting member 6 connected to the connecting base 5, comprising a driving portion 60 and a rotating shaft 61, wherein the rotating shaft 61 is connected to the bottom of the housing 1 to drive the housing 1 to rotate;

[0081] A control device is connected to the collecting member 3 and the driving unit 60 to adjust the housing 1 to rotate to a corresponding angle according to the information collected by the collecting member 3 .

[0082] Specifically, the housing 1 and the related devices in the housing 1 will be fixedly connected to the external structure through the connecting base 5, and the connection between the housing 1 and the connecting base 5 will be realized through the adjusting member 6. The driving part 60 of the adjusting member 6 is fixedly connected to the connecting base 5, and its rotating shaft 61 is connected to the bottom of the housing 1. When the two are connected, the housing 1 can rotate when the driving part 60 drives the rotating shaft 61 to rotate, that is, the angle of the housing 1 on the connecting base 5 will be controlled by the adjusting member 6. The driving part 60 is specifically selected as a driving motor in this embodiment.

[0083] This arrangement enables the shell 1 , that is, the angle of the acquisition member 3 , to be adjusted as needed during subsequent data acquisition, thereby achieving a better acquisition effect for the target object.

[0084] Furthermore, in some embodiments, the adjusting member 6 and the connecting base 5 are detachably connected.

[0085] Specifically, a mounting seat 62 is provided between the adjusting member 6 and the connecting base 5, the adjusting member 6 is fixedly connected in the mounting seat 62, and electric push rods 620 are fixedly connected on both sides of the mounting seat 62, and the extension and retraction directions of the electric push rods 620 on both sides are coaxial;

[0086] The two electric push rods 620 are each provided with a positioning block 621 at one end away from the mounting seat 62, and the connecting base 5 is provided with a vertical plate 50 corresponding to the two electric push rods 620, and the opposite surfaces of the two vertical plates 50 are each provided with a positioning groove corresponding to the positioning block 621;

[0087] The mounting seat 62 is fixedly connected to the connecting base 5 by inserting the positioning blocks 621 of the electric push rods 620 on both sides into the positioning grooves at the same time.

[0088] In this arrangement, when the electric push rods 620 on both sides of the mounting seat 62 are extended, the positioning blocks 621 at the ends of the two electric push rods 620 are simultaneously abutted against the positioning grooves, thereby realizing the fixed connection between the mounting seat 62 and the connecting base 5, that is, realizing the fixed connection between the collecting member 3 and the connecting base 5. When disassembly is required, it is only necessary to control the two electric push rods 620 to retract so that the two positioning blocks 621 are separated from the positioning grooves, thereby releasing the connection between the mounting seat 62, the adjusting member 6, and the housing 1 and the connecting base 5.

[0089] Furthermore, in some embodiments, the connecting base 5 includes:

[0090] A heat dissipation base 51, wherein a heat dissipation gap is provided;

[0091] One or more adsorbing members 52 are disposed on the bottom surface of the heat dissipation base 51 .

[0092] Specifically, the connecting base 5 includes two heat dissipation and ventilation bases and a plurality of adsorption components 52, wherein the adsorption components 52 are specifically selected as suction cups, and the two heat dissipation and ventilation bases are stacked and connected in the vertical direction with a heat dissipation gap therebetween, and a plurality of ventilation holes are provided on the heat dissipation and ventilation bases.

[0093] Furthermore, in some embodiments, the collecting component 3 further includes:

[0094] A power supply unit 31;

[0095] A data processing unit 32, which is electrically connected to the data acquisition unit 30;

[0096] The communication unit 33 is electrically connected to the data processing unit 32 and the power supply unit 31 .

[0097] This arrangement enables each unit in the acquisition component 3 to work under the power supply of the power supply unit 31, the data processing unit 32 to process and analyze the data acquired by the data acquisition unit 30, and the communication unit 33 to transmit the analysis result information to the outside.

[0098] At the same time, the acquisition component 3 also includes a storage unit, which is used to store data processed by the data processing unit 32, and the communication unit 33 is used to perform wired or wireless communication with other devices or systems to receive or send data; when transmitting data, it includes transmission path one and transmission path two, and transmission path two is a backup path. Transmission path one is the main data transmission path, which is responsible for transmitting the data collected by the acquisition module to the background web page or other data processing equipment after analysis. Transmission path two is a backup data transmission path, which is used when transmission path one fails or is unavailable. It provides redundant channels to ensure reliable data transmission, and transmission path two adopts wireless communication technology.

[0099] The communication unit 33 includes wired communication and wireless communication, and the wired communication is a wired interface;

[0100] Furthermore, in some embodiments, the vehicle-mounted data acquisition device further includes:

[0101] a cooling fan 12, which is disposed on a side of the mounting and disassembly plate 2 away from the collecting member 3, and the cooling fan 12 is electrically connected to the power supply unit 31;

[0102] The mounting and disassembly plate 2 and the side of the housing 1 facing the cooling fan 12 are hollowed out with multiple holes.

[0103] This arrangement enables the cooling fan 12 to generate an airflow perpendicular to the mounting and disassembly plate 2, so that the collecting component 3 installed on the mounting and disassembly plate 2 can obtain heat dissipation and cooling from the airflow generated by the cooling fan 12 during operation, which is beneficial to the operation of the collecting component 3.

[0104] Finally, when using the vehicle-mounted data acquisition device provided by the present application, the user installs the heat dissipation and ventilation base on the platform of the vehicle through a suction cup, and then the user can use the electric push rod 620 on the mounting seat 62 to make the positioning block 621 engage with the positioning groove on the vertical plate 50, so that the mounting seat 62 and the heat dissipation and ventilation base are connected. After that, the adjustment member 6 connected to the mounting seat 62, the shell 1 and the acquisition member 3 in the shell 1 can be used normally. When the data acquisition unit 30 captures the facial angle during use, the shell 1 is driven to rotate through the driving part 60 and the rotating shaft 61, so that the acquisition member 3 completes the capture and monitoring of the driver's state at a suitable angle;

[0105] When disassembly is required, for example, when the collecting member 3 fails, the user can start the electric push rod 620 to retract the positioning block 621, thereby separating the adjusting member 6 from the connecting base 5, and further open the housing 1 through the opening and closing door 110 on the operation port, and then hold the operating rod 43 to apply pressure to drive the squeezing rod 41 to squeeze the spring 40, so that the clamping block 42 releases the clamping connection with the installation and disassembly plate 2, and the installation and disassembly plate 2 can be disassembled. At this time, the collecting member 3 on the installation and disassembly plate 2 can be repaired.

[0106] In a second aspect, the present application provides an on-vehicle data acquisition method based on the above-mentioned on-vehicle data acquisition device.

[0107] A vehicle-mounted data collection method comprises the following steps:

[0108] S100, acquiring a driver's face image collected at a set collection angle;

[0109] S200, obtaining the driver's face angle according to a preset face angle recognition model;

[0110] S300, determining whether the driver's face angle is within a set angle range;

[0111] S400: If not, adjust the acquisition angle according to the driver's face angle, and reacquire the driver's face image.

[0112] In this way, after identifying the driver's facial image and obtaining the driver's facial angle, it is further determined whether the current angle is within the set angle range, and if it is not within the set angle range, the rotating acquisition component 3 is rotated to align with the driver's face until it is ensured that the acquisition component 3 is facing the driver's face, thereby obtaining clearer and more accurate image data; compared with the existing technology without rotational alignment, this design can reduce the acquisition error caused by external factors such as changes in the driver's position or vibrations of the vehicle body, and improve the reliability of data acquisition.

[0113] The preset face angle recognition model is realized by combining face recognition technology and motion control algorithm, and the sensor types involved include cameras, infrared sensors and TOF sensors. Among them, the camera is the most commonly used sensor type, which performs face recognition by capturing face images. In order to realize the face following function, the system first needs to perform face detection through the data acquisition unit 30 to determine the position of the face in the image. Then, according to the position information of the face, the system can calculate the angle that needs to be rotated, and drive the corresponding motion mechanism (i.e., the driving unit 60) to realize the rotation of the acquisition unit 3, so that the data acquisition unit 30 of the acquisition unit 3 is always aimed at the face.
