[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0043] In this application, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0044] To reduce the overall cost of vehicles, this application provides an environmental information acquisition system, the specific structure of which can be found in [reference needed]. Figure 1 ( Figure 1 (Taking only four audio devices 200 as an example for demonstration), specifically including: an image acquisition system 100 and at least one audio device 200, wherein the audio device 200 is connected to the host 40 through a serializer 122 in the image acquisition system 100.
[0045] In this surround-view audio system, the audio device 200 is connected to the host 40 via a serializer 122 in the image acquisition system 100. This allows the serializer 122 to receive clock signals from the host 40 and interact with the host 40 for audio data. Therefore, this solution can load the audio data of the audio device 200 onto the image acquisition system 100, enabling the image acquisition system 100 to transmit the audio data of the audio device 200 to the host 40, thus achieving audio data transmission from the audio device 200. It is evident that the transmission of audio data from the audio device 200 is achieved solely using the image acquisition system 100, thereby reducing the use of control chips and wiring harnesses. This system-level integration reduces the overall cost of the vehicle.
[0046] See Figure 2 In this embodiment, the environmental information acquisition system also includes a protocol conversion module 300. The protocol conversion module 300 is disposed between the host 40 and the image acquisition system 100. Specifically, the first end of the protocol conversion module 300 is connected to the host through the first bus 30, and the second end of the protocol conversion module 300 is connected to the image acquisition system 100 through the second interface 20.
[0047] One of the functions of the second interface 20 is to send the acquired clock signal to the image acquisition system. The clock signal of the second interface 20 is obtained by the protocol conversion module 300 converting the clock signal provided by the first bus 30. A first interface 10 is provided between the serializer 122 of the image acquisition system 100 and the audio device 200. The clock signal of the first interface 10 is obtained by the image acquisition system 100 forwarding the clock signal of the second interface 20. The first interface 10 can send the acquired clock signal to its corresponding audio device 200, so the audio device 200 can receive the clock signal.
[0048] The types of the first interface 10 and the second interface 20 can be selected according to design requirements. For example, in this embodiment, both the first interface 10 and the second interface 20 are PDM interfaces. The PDM interface has two ports: one for transmitting clock signals and the other for transmitting data signals. It should be noted that the PDM interface is already very mature in existing technology and will not be described in detail here. When both the first interface 10 and the second interface 20 are PDM interfaces, the audio data of the audio device 200 can be loaded onto the image acquisition system 100 without affecting the transmission of the image acquisition system 100. That is, the image acquisition system 100 can transmit the audio data of the audio device 200 to the protocol conversion module 300. Through the protocol conversion module 300, the audio data of the audio device 200 can be transmitted to the host 40 in the vehicle, thus realizing the transmission of the audio data of the audio device 200. Therefore, the transmission of the audio data of the audio device 200 is achieved using only the image acquisition system 100 and the protocol conversion module 300, thus reducing the use of control chips and wiring harnesses. This integration at the system solution level reduces the overall cost of the vehicle.
[0049] The audio device 200 is connected to the serializer 122 in the image acquisition system 100 through a first interface 10 that corresponds to it. Specifically, the first interface 10 that corresponds to it refers to the first interface 10 that corresponds to the audio device 200.
[0050] For example, such as Figure 2 As shown, counting from left to right, the four audio devices 200 are the first audio device 200 to the fourth audio device 200, and the four first interfaces 10 are the first first interface 10 to the fourth first interface 10. The first audio device 200 corresponds to the first first interface 10, the second audio device 200 corresponds to the second first interface 10, the third audio device 200 corresponds to the third first interface 10, and the fourth audio device 200 corresponds to the fourth first interface 10. The first audio device 200 is connected to the image acquisition system 100 through the first first interface 10, the second audio device 200 is connected to the image acquisition system 100 through the second first interface 10, the third audio device 200 is connected to the image acquisition system 100 through the third first interface 10, and the fourth audio device 200 is connected to the image acquisition system 100 through the fourth first interface 10.
[0051] See Figure 2 The environmental information acquisition system may also include a protocol conversion module 300, and the image acquisition system 100 is connected to the protocol conversion module 300 through the second interface 20.
[0052] The protocol conversion module 300 is connected to the host 40 via the first bus 30, enabling data communication with the host and receiving clock signals from the host. The first bus 30 is a bus capable of transmitting audio and image data. The protocol conversion module 300 performs protocol conversion on the data transmitted through the second interface 20 to convert it into data conforming to the communication protocol of the first bus. In other words, the protocol conversion module 300 can transmit data from the image acquisition system 100 and the audio device 200 to the host 40.
[0053] In a specific example, the first bus 30 is a TDM bus.
[0054] It should be noted that the TDM bus is already a very mature technology, and will not be described in detail here.
[0055] In another specific example, the first bus 30 is an I2S (Inter-IC Sound, integrated circuit built-in audio) bus.
[0056] It should be noted that the I2S bus is already a very mature technology, and will not be described in detail here.
[0057] The two examples above only illustrate two specific implementations of the first bus 30. In practical applications, including but not limited to these, any bus capable of transmitting data is within the protection scope of this application, and no specific limitations are made here.
[0058] See Figure 2 The clock signal obtained by the second interface 20 is converted by the protocol conversion module 300 to obtain the clock signal provided by the first bus 30. In other words, the protocol conversion module 300 is used to convert the clock signal provided by the first bus 30 into a clock signal for controlling the audio device 200, and send it to the audio device 200 through the first interface 10.
[0059] The clock signal of the first interface 10 is obtained by the serializer 122 in the image acquisition system 100 forwarding the clock signal of the second interface 20. In other words, the image acquisition system 100 is used to forward the clock signal of the second interface 20 so that it can be transmitted to the audio device 200 through the first interface 10.
[0060] In this surround-view audio system, the clock signal of the second interface 20 is obtained by the protocol conversion module 300 converting the clock signal of the first bus 30, and the clock signal of the first interface 10 is obtained by the image acquisition system 100 forwarding the clock signal of the second interface 20. Therefore, the audio device 200 can receive the clock signal, and thus the first interface 10 and the second interface 20 can work normally. Furthermore, since the first interface 10 and the second interface 20 are PDM interfaces, the audio data of the audio device 200 can be loaded onto the image acquisition system 100 without affecting its transmission. That is, the image acquisition system 100 can transmit the audio data of the audio device 200 to the protocol conversion module 300. Through the protocol conversion module 300, the audio data of the audio device 200 can be transmitted to the host 40 in the vehicle, thereby realizing the transmission of the audio data of the audio device 200. Therefore, it can be seen that the transmission of audio data of audio device 200 is realized by using only image acquisition system 100 and protocol conversion module 300, thus reducing the use of control chip and wiring harness. That is, integration is achieved at the system solution level, thereby reducing the overall cost of vehicle.
[0061] Furthermore, as can be seen from the above, Figure 2 In the example shown, the audio data transmission path of the audio device 200 is as follows: audio device 200 → first interface 10 → image acquisition system 100 → second interface 20 → protocol conversion module 300 → first bus 30 → host 40.
[0062] Another embodiment of this application provides a specific implementation of a protocol conversion module 300 for a vehicle, applicable to situations where the first bus 30 is a TDM bus. The specific structure of this embodiment can be found in [reference needed]. Figure 3 ( Figure 3 Only Figure 2 Based on the above embodiments, this implementation method differs from any of the embodiments provided in that:
[0063] In this embodiment, the protocol conversion module 300 is an A2B chip 210.
[0064] It should be noted that the A2B chip 210 is already a very mature technology, and will not be described in detail here.
[0065] The above is only one specific implementation of the protocol conversion module 300. In practical applications, including but not limited to this, any implementation that can achieve the same function is within the protection scope of this application and is not specifically limited here.
[0066] Another embodiment of this application provides a specific implementation of an image acquisition system 100, the specific structure of which can be found in [reference needed]. Figure 4( Figure 4 exist Figure 2 Based on this, only four sub-image acquisition systems 120 will be used as an example for demonstration. Figure 5 ( Figure 4 exist Figure 2 Based on this, only two sub-image acquisition systems 120 are used as examples for demonstration. See [link / reference]. Figure 4 and Figure 5 The image acquisition system specifically includes at least one sub-image acquisition system 120. Different sub-image acquisition systems have different image acquisition directions. Each sub-image acquisition system 120 includes an image acquisition device 121 and a serializer 122. In the sub-image acquisition system 120, the image acquisition device 121 is connected to the serializer 122 via a second bus 50. The image acquisition device 121 is connected to the host computer via the serializer 122. The audio device 200 is connected to the host computer via the serializer 122 in its corresponding sub-image acquisition system 120.
[0067] It should be noted that the image acquisition device 121 and the serializer 122 are already very mature in the prior art, and will not be described in detail here.
[0068] The second bus 50 is a bus capable of transmitting video / image data. Because the second bus 50 can transmit video / image data, the video data of the image acquisition device 121 is transmitted to the serializer 122 through the second bus 50.
[0069] In a specific example, the second bus 50 is a MIPI (Mobile Industry Processor Interface) bus.
[0070] It should be noted that the MIPI bus is already a very mature technology, and will not be described in detail here.
[0071] The above example only illustrates one specific implementation of the second bus 50. In practical applications, it includes, but is not limited to, this example. It can be determined according to the specific circumstances and is within the protection scope of this application.
[0072] The audio device 200 is connected to any serializer 122 through a corresponding first interface 10. It should be noted that the corresponding first interface 10 has been described in detail in the above embodiments and will not be repeated here.
[0073] See a specific example. Figure 4There is a one-to-one correspondence between the audio device 200 and the serializer 122. The audio device 200 is connected to the corresponding serializer 122 through a first interface 10. It should be noted that the first interface 10 has been described in detail in the above embodiments and will not be repeated here. At this time, the serializer 122 has a first end, a second end, and a third end; the first end of the serializer 122 is connected to the host 40 through a first bus 30; the audio device 200 is connected to the second end of the serializer 122 through the first interface 10; and the image acquisition device 121 is connected to the third end of the serializer 122 through a second bus.
[0074] For example, such as Figure 4 As shown, counting from left to right, the four audio devices 200 are the first audio device 200 to the fourth audio device 200, the four first interfaces 10 are the first first interface 10 to the fourth first interface 10, and the four serializers 122 are the first serializer 122 to the fourth serializer 122. The first audio device 200 corresponds to the first first interface 10, the second audio device 200 corresponds to the second first interface 10, the third audio device 200 corresponds to the third first interface 10, and the fourth audio device 200 corresponds to the fourth first interface 10. The first audio device 200 corresponds to the first serializer 122, the second audio device 200 corresponds to the second serializer 122, the third audio device 200 corresponds to the third serializer 122, and the fourth audio device 200 corresponds to the fourth serializer 122. The first audio device 200 is connected to the first serializer 122 through the first first interface 10, the second audio device 200 is connected to the second serializer 122 through the second first interface 10, the third audio device 200 is connected to the third serializer 122 through the third first interface 10, and the fourth audio device 200 is connected to the fourth serializer 122 through the fourth first interface 10.
[0075] In another specific example, see Figure 5 The serializer 122 may have two or more second terminals. In this case, the serializer 122 is connected to at least two audio devices 200 through its respective second terminals. The audio devices 200 are connected to the second terminals of the serializer 122 corresponding to them through their respective first interfaces 10. It should be noted that the first interfaces 10 corresponding to each other have been described in detail in the above embodiments and will not be repeated here.
[0076] For example, such as Figure 5As shown, each serializer 122 has two second terminals. Counting from left to right, the four audio devices 200 are designated as the first audio device 200 to the fourth audio device 200, the four first interfaces 10 are designated as the first first interface 10 to the fourth first interface 10, and the two serializers 122 are designated as the first serializer 122 and the second serializer 122. The first audio device 200 corresponds to the first first interface 10, the second audio device 200 corresponds to the second first interface 10, the third audio device 200 corresponds to the third first interface 10, and the fourth audio device 200 corresponds to the fourth first interface 10. The first serializer 122 corresponds to the first audio device 200 and the second audio device 200, respectively, and the second serializer 122 corresponds to the third audio device 200 and the fourth audio device 200, respectively. The first audio device 200 is connected to the first serializer 122 through the first first interface 10, the second audio device 200 is connected to the first serializer 122 through the second first interface 10, the third audio device 200 is connected to the second serializer 122 through the third first interface 10, and the fourth audio device 200 is connected to the second serializer 122 through the fourth first interface 10.
[0077] The two examples above only illustrate two specific implementations of audio device 200 being connected to any serializer 122 through its corresponding first interface 10. In practical applications, there are other implementations, including but not limited to these. No specific limitation is made here, and the specific implementation can be determined according to the specific circumstances. All of these are within the protection scope of this application.
[0078] See Figure 4 and Figure 5 The image acquisition system 100 also includes a deserializer 110. The serializers 122 of each sub-image acquisition system 120 in the image acquisition system 100 are connected to the host 40 through the deserializer 110. Specifically, the serializer 122 is connected to the deserializer 110 through the serial bus 60, the deserializer 110 is connected to the protocol conversion module 300 through the second interface 20, and the protocol conversion module 30 is connected to the host 40 through the first bus 30.
[0079] In one specific example, serial bus 60 is a GMSL (Gigabit Multimedia Serial Links) bus.
[0080] It should be noted that the GMSL bus has been described in detail in the above embodiments and will not be repeated here.
[0081] The above example only illustrates one specific implementation of the serial bus 60. In practical applications, there are other implementations, including but not limited to this one. No specific limitation is made here. The implementation can be determined according to the specific circumstances, and all are within the protection scope of this application.
[0082] It should be noted that the deserializer 110 is already a mature technology and will not be described in detail here. Furthermore, the second interface 20 has been described in detail in the above embodiments and will not be repeated here.
[0083] In this embodiment, the transmission path of audio data of audio device 200 is as follows: audio device 200 → first interface 10 corresponding to audio device 200 → serializer 122 corresponding to audio device 200 → serial bus 60 → deserializer 110 → second interface 20 → protocol conversion module 300 → first bus 30 → host 40.
[0084] In this embodiment, both the first interface 10 and the second interface 20 can be PDM interfaces, so that the audio data of the audio device 200 can be loaded onto the serial bus 60 without affecting the transmission of the video data of the image acquisition device 121. Therefore, the image acquisition system 100 can transmit the above-mentioned audio data to the protocol conversion module 300 without affecting the transmission of the video data of the image acquisition device 121.
[0085] The above is only one specific implementation of the image acquisition system 100. In practical applications, it includes, but is not limited to, this implementation. It can be determined according to the specific circumstances and is within the protection scope of this application.
[0086] Another embodiment of this application provides yet another specific implementation of the image acquisition system 100, the specific structure of which can be found in [reference needed]. Figure 6 ( Figure 6 Only Figure 4 Based on the presentation) or Figure 7 (7 only) Figure 5 Based on the above two embodiments, this implementation method differs from the implementation methods provided in that:
[0087] In this embodiment, the deserializer 110 is also connected to the host 40 in the vehicle via a third bus 70, and the communication protocol of the third bus 70 is the same as that of the second bus 50. For example, if the second bus 50 is a MIPI bus, then the third bus 70 is a MIPI bus.
[0088] In this embodiment, the transmission path of the video data of the image acquisition device 121 is as follows: image acquisition device 121 → second bus 50 → serializer 122 in the same sub-image acquisition system 120 as the image acquisition device 121 → serial bus 60 → deserializer 110 → third bus 70 → host 40 in the vehicle.
[0089] The above is only one specific implementation of the image acquisition system 100. In practical applications, it includes, but is not limited to, this implementation. It can be determined according to the specific circumstances and is within the protection scope of this application.
[0090] Another embodiment of this application provides another specific implementation of an environmental information acquisition system, which is applicable to the following situation: the image acquisition system 100 adopts the implementation method provided in any one of the three embodiments above. The specific structure of this implementation can be found in [reference needed]. Figure 8 ( Figure 8 Only Figure 6 Based on the presentation) or Figure 9 ( Figure 9 Only Figure 7 Based on the above embodiments, this implementation method differs from any of the embodiments provided in that:
[0091] In this embodiment, the audio device 200 is integrated within the target sub-image acquisition system. The target sub-image acquisition system is a sub-image acquisition system 120 that includes a serializer 122 connected to the audio device 200.
[0092] For example, counting from left to right, such as Figure 8 As shown, four audio devices 200 are designated as the first audio device 200 to the fourth audio device 200, and four sub-image acquisition systems 120 are designated as the first sub-image acquisition system 120 to the fourth sub-image acquisition system 120. For the first audio device 200, the first sub-image acquisition system 120 is the target sub-image acquisition system. For the second audio device 200, the second sub-image acquisition system 120 is the target sub-image acquisition system. For the third audio device 200, the third sub-image acquisition system 120 is the target sub-image acquisition system. For the fourth audio device 200, the fourth sub-image acquisition system 120 is the target sub-image acquisition system. The first audio device 200 is integrated within the first sub-image acquisition system 120, the second audio device 200 is integrated within the second sub-image acquisition system 120, the third audio device 200 is integrated within the third sub-image acquisition system 120, and the fourth audio device 200 is integrated within the fourth sub-image acquisition system 120.
[0093] For example, such as Figure 9As shown, counting from left to right, the four audio devices 200 are designated as the first to fourth audio devices 200, and the two sub-image acquisition systems 120 are designated as the first and second sub-image acquisition systems 120. For the first and second audio devices 200, the first sub-image acquisition system 120 is the target sub-image acquisition system. For the third and fourth audio devices 200, the second sub-image acquisition system 120 is the target sub-image acquisition system. The first and second audio devices 200 are integrated within the first sub-image acquisition system 120, and the third and fourth audio devices 200 are integrated within the second sub-image acquisition system 120.
