For example, as shown in fig. 3, a pad 11 may be reserved at the bottom of the HUD host 1, all external connection interfaces of the HUD host 31 are collectively connected through a group of pogopin21, front and rear camera signals, camera power supply, a reverse signal, an ACC signal, an OBD device communication signal (serial port), and external power supply may all be collectively connected to the inside of the base 3, an adapter board 2 is installed in the base, and then the signals are sent to the host 1 through the pogopin21 of the adapter board 2.

According to the technical scheme of the embodiment of the invention, the camera can be externally connected without arranging the switching chip in the HUD equipment by arranging the pogopin connector, so that the cost of the HUD equipment can be reduced, and the use flexibility of the HUD equipment is improved. In addition, the pogopin connector can also improve the reliability of connection of the patch panel and the HUD device.

Optionally, status information may be reported to the HUD device through the patch panel, where the status information includes: the working state of a signal conversion chip in the adapter plate and the working state of a power supply control template in the adapter plate are respectively controlled by the signal conversion chip and the power supply control template; and receiving configuration information sent by the HUD device after analyzing the state information, wherein the configuration information is used for configuring the adapter plate.

Signal conversion can be performed through a signal conversion chip in the adapter board: and converting the first target signal received by the first interface on the adapter board into a second target signal corresponding to the interface type of the second interface on the adapter board, and sending the second target signal to the host through the second interface.

According to the technical scheme of the embodiment of the invention, the signal conversion is carried out through the signal conversion chip in the adapter plate, so that the communication between the HUD equipment and the external equipment can be realized under the condition that the existing structures of the HUD equipment and the external equipment are not changed, the wiring is convenient, the host cost can be saved, and the updating flexibility of the host is improved.

The first interface may be an AHD (Analog High Definition) interface, the second interface may be an MIPI (Mobile Industry Processor interface), and correspondingly, the first target signal may be an AHD signal sent by the first camera (for example, a front camera or a rear camera), and the second target signal may be an MIPI signal.

Optionally, in this embodiment, when the first target signal is a target AHD signal sent by the first camera, receiving the first target signal through the first interface on the interposer includes: receiving a target AHD signal sent by a first camera through a target AHD interface on the adapter plate; converting the first target signal to a second target signal by the interposer includes: converting the target AHD signal into an MIPI signal through the adapter plate; transmitting the second target signal to the host through the second interface includes: and sending the target MIPI signal to the host through the target MIPI interface.

According to the technical scheme of the embodiment of the invention, the adapter board is used for converting the AHD signal and the MIPI signal, so that the connection between the on-board universal video interface (MIPI) and the external universal video interface (AHD) is realized, and the AHD host can adapt to most cameras on the market.

The first camera can be a front camera and also can be a rear camera, the rear camera can get electricity from a reversing lamp, and the electricity of the front camera can be provided by a host.

After the rear camera gets the electricity from the reversing lamp, the HUD host computer can be informed to Switch to the rear camera through a Switch signal, and at the moment, the collected image information is sent to the adapter plate through an AHD interface and is converted into a mipi signal to be sent to the host computer. For the front camera, the image signal of the front camera can also be sent to the adapter board through the AHD interface and then converted into a mipi signal to be sent to the host. The Switch may be to the rear camera display when the "Switch" signal is active and back to the front camera display when the "Switch" signal is inactive.

The switching between the front camera and the rear camera may be performed based on a user operation, for example, a specific operation is performed on the HUD device, the front camera, or the rear camera, for example, a switching button (a physical button or a virtual button displayed on a screen of the HUD device or a control button connected to the HUD device in a wireless/wired manner) is clicked, or a voice control instruction (for example, "turn on the front camera/turn on the rear camera/turn off the front camera" or the like) is received, or the front camera or the rear camera is turned on or the like, thereby triggering the switching between the front camera and the rear camera.

Optionally, in this embodiment, before receiving, through a target AHD interface on the adapter board, a target AHD signal sent by the first camera, a target switching signal is received through a third interface on the adapter board, where the target switching signal is used to instruct to switch a currently used camera to the first camera; sending the target switching signal to the host through a fourth interface on the adapter plate; receiving a switching confirmation signal returned by the host through a fourth interface; and responding to the switching confirmation signal, and enabling the target AHD interface through the adapter plate so as to switch the currently used camera to the first camera.

For example, by operating the first camera or clicking a specific button, a target switching signal is generated. And the first camera sends the target switching signal to the adapter plate through the third interface. And the adapter plate sends the target switching signal to the host through the fourth interface. The host may or may not return a switch acknowledgement signal. The patch panel may enable the first camera (e.g., enable an AHD interface corresponding to the first camera from which the AHD signal sent by the first camera is received) after receiving the target switching signal or the switching confirmation signal.

According to the technical scheme of the embodiment of the invention, after the target switching signal is received, the camera is switched according to the switching confirmation signal returned by the host, so that the control capability of the host on the camera can be improved, and the flexibility of the camera in use is ensured.

In the related art, in the HUD device, various functions which are not used for a long time are generally integrated on the host, so that a client buys a list for the functions which are not used, and the wiring is messy, which affects the driving.

Optionally, in this embodiment, in addition to the first interface and the second interface, the patch panel may also be provided with other communication interfaces.

For example, as shown in fig. 3, in cooperation with the HUD host 1, AHD signals output from the front camera 4 (via the interface 41 on the front camera) and the rear camera (221, 222 are front and rear camera interfaces, respectively) may be converted into a video universal bus interface (mipi) via a patch board, and connected to the HUD host 1 via pogopin21 (the configuration of pogopin21 may be as shown in fig. 4). Meanwhile, a power supply 223, an OBD (On-Board Diagnostic) device, a car start signal, an FM antenna signal, and the like may be connected through the pogopin 21. The Integrated adaptor board may be as shown in fig. 5, wherein the UART is a universal asynchronous receiver/transmitter (UART), which is a universal serial data bus (usb), ic is an Inter-Integrated Circuit (ic), and the ACC is Adaptive Cruise Control (Adaptive Cruise Control).

As an optional implementation manner, a target serial signal sent by an on-board automatic diagnostic system OBD device may be received through a first serial interface on the interposer, where the target serial signal carries driving information of a target vehicle where the HUD device is located; and sending the target serial port signal to the host through a second serial port on the adapter plate.

As another optional embodiment, a first power supply signal sent by an on-board automatic diagnostic system OBD device may be received through a fifth interface on the interposer, where a power supply voltage of the first power supply signal is a first voltage; adjusting the power supply voltage from a first voltage to a second voltage through the adapter plate, wherein the voltage value of the second voltage is a target voltage threshold value; and sending a second power supply signal to the host through a sixth interface on the adapter plate, wherein the power supply voltage of the second power supply signal is a second voltage.

For example, OBD equipment obtains driving information from the car machine, then sends data for the HUD host computer through the serial ports, and wherein serial signals carries out the switching through the keysets. OBD equipment can acquire the power and supply power for the HUD host computer through the keysets after the steady voltage from the car.

It should be noted that the OBD device may send driving information only through the serial interface (information interaction function), may also supply power to the HUD device only through a specific interface (e.g., the fifth interface and the sixth interface) through voltage stabilization (voltage stabilization power supply function), and may also simultaneously execute two functions, and the specific function of the OBD device may be set as needed, which is not specifically limited in this embodiment.

As another optional implementation, a target frequency modulation FM antenna signal sent by the host is received through a seventh interface on the adapter board; the target FM antenna signal is transmitted by the target antenna on the patch panel via the carrier circuit on the patch panel.

For example, an FM antenna signal may be sent by the host to the patch panel, passed through a carrier circuit on the patch panel, and finally transmitted through the power supply ground into the air.

As another optional implementation, the target control signal may be received through an eighth interface on the patch panel, where the target control signal is one of: a power supply signal, an automobile starting signal and a reversing signal for supplying power to the second camera; and sending the target control signal to the host through a ninth interface on the adapter board so as to enable the host to execute response operation corresponding to the target control signal.

For example, in a case where the target control signal is a power supply signal for supplying power to the second camera (e.g., a front camera), the host may supply power to the second camera after receiving the power supply signal.

For another example, when the target control signal is an automobile start signal, after receiving the automobile start signal, the host may send a power supply signal to the front camera through the adapter plate, so as to turn on the front camera.

For another example, in a case where the target control signal is a reverse signal, after receiving the reverse signal, the host may determine to activate the rear camera, and acquire image information from the rear camera.

Through the technical scheme of the embodiment of the invention, the integration and customization of front and back cameras, OBD equipment communication interfaces, automobile starting signals, power supplies, antenna transmission and other multi-functions can be realized, different accessories are provided according to different user groups, and the individual requirements of users are met. Meanwhile, great convenience is provided for software and hardware upgrading of the host.

It should be noted that, the keyset can be HUD function expansion board, through it realize around the camera connect, the OBD communication, ACC signal input, FM antenna emission, functions such as external power source input, through this keyset, external equipment can carry out the degree of depth customization according to different user's demands, make the host computer platform interface standardized, save the host computer cost, increase the flexibility that the host computer is more upgraded, it is succinct to lay wire simultaneously, the mixed and disorderly problem of HUD equipment external connection cable has been avoided.
