[0045] Reference Figures 1 to 4 The diagram shows a structural schematic of a vehicle-mounted camera assembly according to an embodiment of this application. The vehicle-mounted camera assembly may specifically include: a housing 10, a camera module 20, a processing module 30, and a wireless communication module 40; the processing module 30 and the wireless communication module 40 are disposed in the housing 10, and the processing module 30 and the wireless communication module 40 are electrically connected; the housing 10 is provided with a groove 11, the camera module 20 is disposed in the groove 11, and the camera module 20 communicates wirelessly through the processing module 30 and the wireless communication module 40.

[0046] In this embodiment, the camera module 20, processing module 30, and wireless communication module 40 are all integrated onto the housing 10. The camera module 20 is positioned within the recess 11 of the housing 10, reducing the space required for the camera module 20 to protrude from the housing 10. This results in a more compact and smaller overall vehicle camera assembly, requiring less space and facilitating installation. Furthermore, the camera module 20 communicates wirelessly with the processing module 30 and the wireless communication module 40, eliminating the need for complex communication wiring harnesses and reducing the space occupied by wiring harnesses in the vehicle cabin. This reduces the space required for the vehicle camera assembly, which is typically scattered and has a cumbersome wiring layout, thus promoting compact installation within the vehicle. The electrical connection between the processing module 30 and the wireless communication module 40 allows the processing module 30 on the housing 10 to directly process the communication signals from the wireless communication module 40, reducing signal delay and improving accuracy.

[0047] For example, in this embodiment of the application, the camera module 20 is used to acquire images, perform photoelectric signal conversion, and transmit the image signal to the processing module 30. For example, the camera module 20 may include a lens 21 and a photosensitive chip 22 (Sensor). The photosensitive chip 22 processes the light incident from the lens 21 to realize the photoelectric signal conversion and transmit the image signal to the processing module 30.

[0048] In this embodiment, for example, the wireless communication module 40 can be a WIFI (Wireless Fidelity) module. The vehicle control unit can be equipped with a WIFI communication module, and the WIFI module can communicate wirelessly with the WIFI communication module, enabling the wireless communication module 40 to transmit image, video, and other information to the vehicle control unit, as well as to perform OTA (Over-the-Air) software or firmware upgrades, bug fixes, or tuning, etc. Alternatively, the wireless communication module 40 can also be a Bluetooth module, enabling wireless communication via Bluetooth connection, etc. This embodiment does not limit the specific type of the wireless communication module 40.

[0049] For example, in this embodiment of the application, the vehicle-mounted camera component can achieve dual-band WIFI connection of 2.4GHz and 5GHz with the vehicle's onboard control unit, thereby allowing for frequency band switching during use. The onboard control unit is usually single-band, and its frequency band can be confirmed at the vehicle's factory, enabling smoother frequency band switching during subsequent use.

[0050] In this embodiment, the processing module 30 can be a System on Chip (SOC) that can implement a MIPI RX (Mobile Industry Processor Interface Receiver) to receive video or image data; ISP (Image Signal Processing) for tasks such as noise cancellation, filtering, automatic exposure, autofocus, HDR correction, and image sharpening; the processing module 30 can also include an encoder for H.265 encoding and compression to encode and compress video or images; and the processing module 30 can also receive and transmit WIFI data. Furthermore, the processing module 30 can interact with the display screen 50 of the monitoring system via UART (Universal Asynchronous Receiver / Transmitter) to transmit information such as WIFISSID (Wireless Fidelity Service Set Identifier) ​​and password.

[0051] In this embodiment of the application, for example, the vehicle-mounted camera component can be a VLMCAM (Visual Language Model Camera), which can be applied to the vehicle control unit's monitoring system for passengers in the vehicle cabin.

[0052] Optionally, in this embodiment, the housing 10 includes a rear cover 12 with a recess 11. The camera module 20 includes a lens 21 and a photosensitive chip 22, with the photosensitive chip 22 disposed in the recess 11 and the lens 21 and photosensitive chip 22 disposed opposite each other. Thus, by providing a recess 11 in the rear cover 12 to form a recessed structure, the photosensitive chip 22 is placed within the recess 11. The recess 11 provides space for the photosensitive chip 22, reducing the space for the camera module 20 to protrude from the housing 10. Furthermore, the photosensitive chip 22, located within the recess 11, can be stably accommodated within the rear cover 12 of the housing 10, resulting in better reliability.

[0053] For example, in this embodiment of the application, the depth of the groove 11 can be 1mm, 1.5mm, 1.6mm or 1.8mm, etc., and can be set according to the actual needs based on the thickness of the photosensitive chip 22 and the thickness of the back cover 12, etc. In this embodiment of the application, the specific depth of the groove 11 is not limited.

[0054] In this embodiment, optionally, the vehicle-mounted camera assembly includes a motherboard 18, which is disposed within the housing 10, with the photosensitive chip 22 offset from the motherboard 18. Specifically, the motherboard 18 is used to implement functions such as power supply, antenna 31 of the wireless communication module 40, the wireless communication module 40 chip, and processing module 30. For example, the motherboard 18 and the photosensitive chip 22 can be electrically connected via wires or jumper wires. During the use of the vehicle-mounted camera assembly, a large current typically flows through the motherboard 18 and the photosensitive chip 22, generating significant heat. In related technologies, the motherboard 18 and the photosensitive chip 22 are usually integrated on the same circuit board, resulting in concentrated heat. In this embodiment, the photosensitive chip 22 is offset from the motherboard 18, thus separating the heat source, reducing the concentrated accumulation of heat, and helping to meet the chip's temperature rise requirements. Simulation tests show that this embodiment can control the temperature rise of the photosensitive chip 22 and the motherboard 18 to below 16°C.

[0055] For example, in this embodiment, the photosensitive chip 22 and the motherboard 18 are offset along the thickness direction of the vehicle-mounted camera assembly, so that the photosensitive chip 22 and the motherboard 18 are not located on the same plane, thus dispersing the heat source. Alternatively, the photosensitive chip 22 and the motherboard 18 can be spaced apart along the height or width direction of the vehicle-mounted camera assembly, etc., and this embodiment does not limit this to any particular configuration.

[0056] Optionally, in this embodiment, the length of lens 21 is less than or equal to 6.5mm, that is, its TTL (Total Track Length) is less than or equal to 6.5mm. Specifically, the length of lens 21 is set along the thickness direction of the vehicle camera assembly. Because the length of lens 21 is small, the overall thickness of the vehicle camera assembly is reduced, which is beneficial for the miniaturization design of the product. For example, the height of lens 21 can be 6.35mm, 6.5mm, or 6mm, etc., and this embodiment does not limit this.

[0057] For example, in the embodiments of this application, the lens 21 can be a consumer-grade lens, that is, a consumer-grade lens 21, rather than a more expensive automotive-grade lens. The height of an automotive-grade lens can typically reach 20mm, thus giving the lens 21 the advantages of low cost, lightweight and miniaturization.

[0058] Optionally, the vehicle-mounted camera assembly includes a first side and a second side arranged opposite to each other, wherein the thickness H1 of the first side is less than or equal to 12mm, and the thickness H2 of the second side is less than or equal to 15mm. This results in both the first and second sides of the vehicle-mounted camera assembly having relatively small thicknesses, leading to a smaller overall structural volume and promoting product miniaturization and portability.

[0059] For example, in the embodiments of this application, the thickness H1 of the first side can be 11.7mm, 11.8mm, 12mm or 11.6mm, etc., and the thickness H2 of the second side can be 14.9mm, 14.8mm, 15mm or 14.5mm, etc. The specific values ​​of the thickness of the first side and the second side are not limited in the embodiments of this application.

[0060] In this embodiment, optionally, the housing 10 includes a middle frame 13 and a rear cover 12 connected to the middle frame 13. The middle frame 13 has a bent portion 14, which, together with the rear cover 12, forms a receiving cavity. The wireless communication module 40 includes an antenna element 31, which is disposed within the receiving cavity. And / or, the outer side of the antenna element 31 has a protruding locking block 32, and the inner side of the bent portion 14 has a locking groove 33, with the locking block 32 engaging with the locking groove 33. Thus, the receiving cavity formed by the bent portion 14 of the middle frame 13 and the rear cover 12 provides a mounting position for the antenna element 31, allowing the antenna element 31 to be integrated onto the middle frame 13 and the rear cover 12. Compared to related technologies where the antenna element 31 is typically disposed on the outer wall of the housing 10, this application further reduces the size of the vehicle camera assembly, resulting in further miniaturization of the product. Through simulation tests, this application integrates the antenna component 31 onto the mid-frame 13 and the rear cover 12, compressing the lateral area of ​​the vehicle camera assembly to 31.7*56.6mm, thus significantly reducing the size of the vehicle camera assembly. Furthermore, by engaging the clip 32 into the slot 33, the antenna component 31 is securely connected to the mid-frame 13, improving the connection reliability and stability of the antenna component 31.

[0061] Optionally, in this embodiment, the vehicle-mounted camera assembly includes a quick-connect electrical connector 15, which is disposed on the housing 10, with at least a portion of the quick-connect electrical connector 15 exposed outside the housing 10. The quick-connect electrical connector 15 is used for electrical connection to the display screen 50. Thus, the quick-connect electrical connector 15 enables electrical connection between the vehicle-mounted camera assembly and the display screen 50. The quick-connect electrical connector 15 allows signals from the camera module 20 to the processing module 30 to be transmitted to the display screen 50, eliminating the need for wiring harnesses on both the vehicle-mounted camera assembly and the display screen 50. This further simplifies the vehicle-mounted camera assembly and the related structure of the display screen 50, improving the ease of installation and removal of the vehicle-mounted camera assembly. Furthermore, using the quick-connect electrical connector 15 for electrical connection avoids the incompatibility issues between various interfaces in related technologies, such as Lightning, Type-C, and Micro USB (Micro Universal Serial Bus).

[0062] In this embodiment, the quick electrical connector 15 may optionally be an elastic electrical contact element. For example, the elastic electrical contact element may be an elastic pin contact element, or a spring pin, i.e., a Pogo Pin or Pin, etc. In addition, the elastic electrical contact element may also be an elastic probe, etc. The specific type of elastic electrical contact element is not limited in this embodiment.

[0063] Specifically, the Pogo Pin is a spring-loaded probe commonly used for connection or testing in electronic devices. It mainly consists of three parts: a plunger, a spring, and a barrel, formed by pre-pressing with precision instruments. The spring-loaded pin provides a stable electrical connection upon contact, while also possessing a certain degree of elasticity to adapt to different contact surfaces. It offers good reliability, flexibility, and miniaturization, enabling reliable electrical connection between the quick-connect component 15 and the display screen 50. Furthermore, it is widely applicable and easy to implement.

[0064] In addition, the quick electrical connector 15 can also be an electrode sheet, etc. The specific type of the quick electrical connector 15 is not limited in the embodiments of this application.

[0065] For example, in this embodiment, the number of quick electrical connectors 15 can be one or more. Multiple quick electrical connectors 15 are spaced apart on the rear cover 12, and can be arranged in an array. Furthermore, multiple quick electrical connectors 15 can also be spaced apart along the length of the rear cover 12, in a uniform or symmetrical distribution, etc. Multiple quick electrical connectors 15 enable multi-channel signal transmission. For example, the multiple quick electrical connectors 15 can be UART GND (Ground), UART TX (Transmit), UART RX (Receive), etc., and can be configured according to actual needs. This embodiment does not limit the specific number and configuration of the quick electrical connectors 15.

[0066] Optionally, the vehicle-mounted camera assembly includes a magnetic component 16, which is disposed on the housing 10. The housing 10 is magnetically attached to the display screen 50 via the magnetic component 16. In this way, the magnetic component 16 achieves a relatively reliable connection between the housing 10 and the display screen 50 of the vehicle-mounted camera assembly. The structure is simple and easy to implement, and it also makes the installation or removal of the vehicle-mounted camera assembly more convenient.

[0067] For example, in this embodiment, there can be two magnetic components 16, which are respectively disposed on both sides of the quick-connect electrical connector 15. Thus, while the vehicle-mounted camera assembly and the display screen 50 are magnetically connected, the quick-connect electrical connector 15 is electrically connected to the electrical contacts 52 on the display screen 50, achieving a fixed connection and circuit conduction between the vehicle-mounted camera assembly and the display screen 50. Furthermore, the magnetic components 16 can also be disposed in other locations on the housing 10. This embodiment does not limit the specific location or number of magnetic components 16.

[0068] In this embodiment, the magnetic element 16 can be a ferromagnetic element, such as a samarium cobalt magnet, neodymium iron boron magnet, or iron oxide magnet. The structure on the display screen 50 corresponding to the magnetic element 16 can be made of a magnetically attractive material, such as iron, cobalt, nickel, or stainless steel. Alternatively, another magnetic element 16 can be provided at a position on the display screen 50 corresponding to the magnetic element 16, etc., and this embodiment is not limited in this respect.

[0069] Optionally, in this embodiment, the vehicle-mounted camera assembly includes a snap-fit ​​connector 60, which is disposed on the housing 10, and the housing 10 is snap-fitted to the display screen 50 via the snap-fit ​​connector 60. In this way, the snap-fit ​​connector 60 achieves a simple and convenient connection between the vehicle-mounted camera assembly and the display screen 50, and also provides good stability and reliability.

[0070] Optionally, in this embodiment, the snap-fit ​​component 60 includes an elastic element 61 and a latch 62, and the housing 10 is provided with a sliding groove; one end of the elastic element 61 is connected to the sliding groove, and the other end of the elastic element 61 is connected to the latch 62, with the latch 62 slidably connected to the sliding groove. Thus, the elastic element 61 provides elastic force, and the latch 62 enables the snap-fit ​​component 60 to engage with the display screen 50. Correspondingly, the display screen 50 has a snap-fit ​​platform at a position opposite to the snap-fit ​​block, and the latch 62 can snap into the snap-fit ​​platform. For example, the elastic element 61 can be a spring.

[0071] For example, during the installation of the vehicle-mounted camera assembly, the latch 62 can be pressed to compress the elastic element 61 and move it inward along the slide groove (i.e., from the latch 62 to the elastic element 61). Then, the latch 62 is aligned with the mounting platform of the display screen 50. Next, the latch 62 is released, and the elastic element 61 drives the latch 62 outward along the slide groove (i.e., from the elastic element 61 to the latch 62), causing the latch 62 to engage with the mounting platform, thus securing the vehicle-mounted camera assembly to the display screen 50. During the disassembly of the vehicle-mounted camera assembly, the latch 62 can be pressed to compress the elastic element 61 and move it inward along the slide groove, disengaging the latch 62 from the mounting platform of the display screen 50. Then, the vehicle-mounted camera assembly can be removed from the display screen 50, thus detaching the vehicle-mounted camera assembly from the display screen 50. The operation is simple and convenient.

[0072] In this embodiment, for example, there can be two snap-fit ​​pieces 60. These two snap-fit ​​pieces 60 achieve snap-fit ​​at two different positions, further improving reliability. The two snap-fit ​​pieces 60 can be located on opposite sides of the quick-connect electrical component 15 and the magnetic component 16, respectively. Thus, while the snap-fit ​​piece 60 is snapped into place with the display screen 50, a magnetic fixation connection and circuit conduction are achieved between the vehicle-mounted camera assembly and the display screen 50.

[0073] For example, in this embodiment, the housing 10 is provided with a quick-connect electrical connector 15, two magnetic components 16, and two snap-fit ​​components 60. The quick-connect electrical connector 15 is located in the middle region of the housing 10. Specifically, the quick-connect electrical connector 15 can be located in the middle region of the mounting position 51, or it can be located in the middle position between the first and second sides of the vehicle camera assembly. The two magnetic components 16 are respectively located on both sides of the quick-connect electrical connector 15, and the two snap-fit ​​components 60 are respectively located on both sides of the magnetic components 16 facing away from the quick-connect electrical connector 15. In this way, when the snap-fit ​​components 60 are snapped into place with the display screen 50, the magnetic attraction and fixing connection between the vehicle camera assembly and the display screen 50 and the circuit conduction are realized, which is simple, convenient, and has good reliability.

[0074] In addition, the snap-fit ​​60 can also be set in other positions of the housing 10. The snap-fit ​​60 can also be a metal elastic buckle 62 or an elastic block, etc. The specific setting position, quantity and type of the snap-fit ​​60 in this embodiment of the application are not limited and can be set according to actual needs.

[0075] For example, in the embodiments of this application, such as Figure 2 As shown, one end of the vehicle-mounted camera assembly in the longitudinal direction may include a cover plate 17, a cover plate adhesive, a lens 21, an adhesive layer 19, a photosensitive chip 22, and a rear cover 12. The thickness of the cover plate 17 and the cover plate adhesive can be 0.85mm, the height of the lens 21 can be 6.35mm, the thickness of the adhesive layer 19 can be 0.15mm, the thickness of the photosensitive chip 22 can be 1.6mm, and the thickness of the rear cover 12 can be 1.6mm. In total, the thickness H1 of one end of the vehicle-mounted camera assembly in the longitudinal direction is only 11.7mm, and the thickness H2 of the other end of the vehicle-mounted camera assembly in the longitudinal direction is 14.9mm. The height H3 of the fabric between the main board 18 and the rear cover 12 of the vehicle-mounted camera assembly is 4.4mm, which greatly reduces the overall volume of the vehicle-mounted camera assembly and is conducive to product miniaturization.

[0078] In summary, the vehicle-mounted camera assembly of the embodiments of this application may include at least the following advantages:

[0079] In this embodiment, the vehicle-mounted camera assembly includes: a housing, a camera module, a processing module, and a wireless communication module. The processing module and the wireless communication module are disposed in the housing and electrically connected. The housing has a recess, and the camera module, electrically connected to the processing module, is disposed in the recess. The camera module communicates wirelessly with the vehicle's main control unit through the processing module and the wireless communication module. This integration of the camera module, processing module, and wireless communication module onto the housing, and the placement of the camera module within the recess, reduces the space required for the camera module to protrude from the housing, resulting in a more compact and smaller vehicle-mounted camera assembly that requires less space for installation. Furthermore, the wireless communication between the camera module and the processing module and the wireless communication module eliminates the need for complex communication wiring harnesses, reducing the space occupied by wiring harnesses in the vehicle cabin. This design reduces the space required for vehicle camera components, which are often scattered and have complex wiring layouts due to the existing design of lenses, processing modules, and communication cables, thus facilitating compact installation within the vehicle. Furthermore, the electrical connection between the processing module and the wireless communication module allows the on-mounted processing module to directly process the communication signals from the wireless communication module, reducing signal latency and improving accuracy.

[0080] This application also proposes a monitoring system, referring to... Figure 5 and Figure 6 The monitoring system includes a display screen 50 and a vehicle-mounted camera assembly. The vehicle-mounted camera assembly is detachably connected to the display screen 50 and electrically connected to it. This facilitates the installation of the vehicle-mounted camera assembly on the display screen 50; for example, the vehicle-mounted camera assembly can be detachably connected to the rear of the screen of the display screen 50. This also enables relatively stable and reliable signal transmission between the vehicle-mounted camera assembly and the display screen 50, and facilitates the removal of the vehicle-mounted camera assembly from the display screen 50, improving the ease of installation and removal between the vehicle-mounted camera assembly and the display screen 50.

[0081] Optionally, in this embodiment, the display screen 50 has a mounting position 51 on its rear side. The vehicle camera assembly is detachably connected to the mounting position 51 via a magnetic component 16 and a snap-fit ​​component 60. For example, the mounting position can be a mounting plate. This allows the vehicle camera assembly to be easily and conveniently detachably connected to the mounting position 51 on the rear side of the display screen 50 through magnetic adsorption and snap-fit. And / or, the display screen 50 includes a power module, which is electrically connected to the vehicle camera assembly. The display screen 50 supplies power to the vehicle camera assembly through the power module. In this way, the power module enables the display screen 50 to provide a relatively stable and reliable power supply to the vehicle camera assembly.

[0082] For example, in this embodiment, the display screen 50 can be a roofbar (two-row screen). Alternatively, the display screen 50 can be a ceiling-mounted screen, a screen behind the seat, or a folding screen, etc. This embodiment does not limit the specific type of the display screen 50. For example, in this embodiment, the display screen 50 can include a mounting position 51. The mounting position 51 can be provided with electrical contacts 52, magnetic blocks 53, and snap-fit ​​terminals for connecting to the vehicle-mounted camera assembly. The electrical contacts 52 do not need to protrude from the mounting position 51; that is, the electrical contacts 52 are flush with the mounting position 51.

[0083] In this embodiment, once the vehicle-mounted camera assembly is installed on the display screen 50, power can be supplied to the vehicle-mounted camera assembly without the need for other power supply components. For example, the vehicle-mounted camera assembly can be powered and used while the display screen 50 is unfolded or opened, and it is turned off and stopped when the display screen 50 is closed.

[0084] The monitoring system of this application embodiment may include at least the following advantages:

The vehicle-mounted camera assembly is detachably connected to the display screen and electrically connected to it. The vehicle-mounted camera assembly includes a housing, a camera module, a processing module, and a wireless communication module. The processing module and the wireless communication module are disposed within the housing and electrically connected. The housing has a recess, and the camera module is electrically connected to the processing module. The camera module is disposed within the recess and wirelessly communicates with the vehicle's main control unit via the processing module and the wireless communication module. By integrating the camera module, processing module, and wireless communication module onto the housing and placing the camera module within the recess, the space required for the camera module to protrude from the housing is reduced, resulting in a more compact and smaller vehicle-mounted camera assembly that requires less space and is easier to install. Furthermore, the camera module communicates wirelessly through the processing module and the wireless communication module, eliminating the need for complex communication wiring harnesses and reducing the space occupied by wiring harnesses in the vehicle cabin. This reduces the space required for vehicle camera components due to the dispersed and cumbersome wiring layout of existing lenses, processing modules, and communication connections, facilitating compact installation within the vehicle. Moreover, the electrical connection between the processing module and the wireless communication module allows the on-mounted processing module to directly process the communication signals from the wireless communication module, reducing signal latency and improving accuracy.

[0086] This application embodiment also provides a vehicle, which includes an on-board control unit and a monitoring system, or an on-board camera assembly. The on-board control unit can control the on-board camera assembly to turn on or off. The on-board control unit is electrically connected to the display screen 50 of the monitoring system, and the on-board control unit and the on-board camera assembly can communicate wirelessly.

[0087] Specifically, the vehicle control unit is equipped with a communication module, such as a Wi-Fi module, to enable wireless communication with the wireless communication module 40 of the vehicle camera assembly. For example, the vehicle control unit and the vehicle camera assembly can achieve dual-band Wi-Fi connectivity of 2.4GHz and 5GHz. The vehicle control unit is typically single-band; the frequency band of the vehicle control unit can be confirmed at the factory, allowing for frequency band switching during subsequent use.

[0088] For example, in the embodiments of this application, the vehicle control unit can be a HU (Head Unit, vehicle infotainment system, commonly known as "vehicle machine"). The vehicle control unit can control the vehicle camera component to turn on or off, that is, when the vehicle is powered off, the power supply of the vehicle camera component is disconnected and it stops working.

[0089] In this application embodiment, for example, the vehicle may include a small car, a medium-sized car, a sedan, a truck, a trailer, a CDV (Car Derived Van), an MPV (multi-Purpose Vehicle), an SUV (Sport Utility Vehicle), etc. The specific type of vehicle is not limited in this application embodiment.

[0091] In this embodiment, the vehicle includes an onboard control unit and a monitoring system, or an onboard camera assembly. The onboard control unit can control the onboard camera assembly to turn on or off. The onboard control unit is electrically connected to the display screen of the monitoring system, and the onboard control unit and the onboard camera assembly communicate wirelessly. The monitoring system includes a display screen and the onboard camera assembly. The onboard camera assembly is detachably connected to the display screen and is electrically connected to the display screen. The onboard camera assembly includes: a housing, a camera module, a processing module, and a wireless communication module. The processing module and the wireless communication module are disposed in the housing, and the processing module and the wireless communication module are electrically connected. The housing has a recess, and the camera module is electrically connected to the processing module. The camera module is disposed in the recess, and the camera module communicates wirelessly with the onboard main control unit through the processing module and the wireless communication module. In this way, the camera module, processing module, and wireless communication module are all integrated onto the housing, with the camera module positioned within a recess in the housing. This reduces the space required for the camera module to protrude from the housing, resulting in a more compact and smaller overall vehicle camera assembly that requires less space, facilitating installation. Furthermore, the camera module communicates wirelessly with the processing module and the wireless communication module, eliminating the need for complex communication harnesses and reducing the space occupied by wiring harnesses in the vehicle cabin. This reduces the space required for the vehicle camera assembly by minimizing the dispersed and cumbersome wiring layout of existing lenses, processing modules, and communication connections, thus promoting compact installation within the vehicle. Moreover, the electrical connection between the processing module and the wireless communication module allows the processing module on the housing to directly process the communication signals from the wireless communication module, reducing signal latency and improving accuracy.
