Detailed Description
Embodiments of the present application are described in further detail below with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the embodiments of the application and are not limiting of the embodiments of the application. It should be further noted that, for convenience of description, only some, but not all of the structures related to the embodiments of the present application are shown in the drawings.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
Along with the rapid development of intelligent network-connected automobiles, the number of bus lines required by an automobile bus network is increased, often up to 20 lines, and the number of bus channels of the bus data recorder on the market at present is usually only 4 lines, 6 lines or 8 lines, so as to meet the requirement of more lines of bus data acquisition, the prior art provides two solutions: according to the first scheme, a plurality of bus data recorders with different bus channel numbers are used simultaneously according to the required bus channel numbers, and as the bus data recorders are independent, if data of all bus channels are to be collected, files generated by each bus data recorder are required to be copied respectively, or network transmission accessories are configured for each bus data recorder to have the function of uploading the generated files to a server, so that the bus data recorders are required to be operated respectively, and a plurality of files to be processed are also generated, and inconvenience is caused; the second scheme is to increase the number of bus channels by configuring a high-performance chip for a single bus data recorder, so that the cost is greatly increased, the number of bus channels which can be supported by the high-performance chip is limited, and in addition, the number of bus channels is fixed after the single bus data recorder is configured with the high-performance chip, so that the resource waste can be caused for an application scene without more bus channels.
Based on this, the embodiment of the application provides a combined bus data recorder, which solves the problems that the inconvenience is caused by that a plurality of independent bus data recorders respectively generate files, the cost is too high due to the fact that the number of bus channels is expanded by a single bus data recorder, the expansion of the number of channels is limited, and the application scene is few.
Fig. 1 is a schematic diagram of a combined bus data recorder 100 according to an embodiment of the present application, which is used in an automobile, and the automobile includes a plurality of bus data nodes, where each bus data node may provide a path of bus data.
The combined bus data recorder 100 comprises at least two extension units 110, each extension unit 110 comprising a plurality of bus interfaces 120 and at least one in-vehicle ethernet interface 130; each bus interface 120 is respectively used for accessing one bus data node to receive bus data; in one embodiment, the bus interface 120 may be a CAN bus interface 120 or a LIN bus interface 120. The extension unit 110 may be a bus data recorder with different types of bus interfaces 120, and may be specifically combined freely according to the user's requirement, so as to meet the requirement of collecting different types of bus data.
Based on the foregoing embodiments, it should be noted that the slave unit 110 may be a bus data recorder having different numbers of bus channels, for example, the number of bus channels is 4, 6 or 8; each bus channel has a corresponding one of the bus interfaces 120, and then the corresponding 4-way bus channel has 4 of the bus interfaces 120,6-way bus channel has 6 of the bus interfaces 120. The number of the extension units 110 of the combined bus data recorder 100 is configured corresponding to the target automobile to be installed, and the number of the bus interfaces 120 of the combined bus data recorder 100 is greater than or equal to the number of bus data nodes of the target automobile; for example, if the number of bus data nodes provided by the target automobile is 20, the extension unit 110 of the combined bus data recorder 100 may be configured as a bus data recorder with 3 bus interfaces 120 having 6 paths and a bus data recorder with 1 bus interface 120 having 4 paths, so that the combined bus data recorder 100 may provide a total bus interface 120 having 3×6+4=22; the extension unit 110 of the combined bus data recorder 100 may be further configured as a bus data recorder with 2 bus interfaces 120 of 8 lines and a bus data recorder with 1 bus interface 120 of 4 lines, so that the combined bus data recorder 100 may provide a total bus interface 120 of 2×8+4=20.
However, since the cost of the bus recorder of the number of different bus interfaces 120 is not linearly related to the number of bus interfaces 120, for example, a bus recorder that can provide 20 bus interfaces needs to be configured with a processor capable of processing 20 bus data, such a processor tends to be very costly, and a processor capable of processing 20 bus data may be less costly than a combination of processors capable of achieving a smaller number of processing lanes for processing the same number of bus data, the combination of bus recorders with fewer processing lanes is more desirable for low cost. Further, the user can further measure the cost of the assembled combined bus data recorder 100 according to the cost of the bus data recorder with different numbers of interfaces to screen the combination according with the production cost under the condition that the number of the available bus interfaces 120 meets the requirement. For example, a bus data recorder with 4 bus interfaces 120 has a cost of a 1 Bus data record with 6 bus interfaces 120The cost of the recorder is a 2 The cost of the bus data recorder with 8 bus interfaces 120 is a 3 Then combination I: the total cost of the 3 bus data recorders with the number of bus interfaces 120 being 6 and the 1 bus data recorder with the number of bus interfaces 120 being 4 is a 1 +3a 2 And combination II: the total cost of the bus data recorder with 2 bus interfaces 120 of 8 paths and the bus data recorder with 1 bus interface 120 of 4 paths is a 1 +2a 3 Thus, in the case that two combinations can likewise provide a number of bus data nodes greater than or equal to the target vehicle, if a 1 +3a 2 ＞a 1 +2a 3 The user may select a first combination based on cost; if a is 1 +3a 2 ＜a 1 +2a 3 The user may select a second combination based on cost.
In addition, due to the different numbers of bus interfaces 120 required by different application scenarios, users can flexibly combine according to specific requirements. For example, the user configures for scenario 1 a combination I that provides 20 bus interfaces 120 in number: 2 bus data recorders with 8 bus interfaces 120 and 1 bus data recorder with 4 bus interfaces 120, a combination II providing 22 bus interfaces 120 is configured for scenario 2: if the number of 3 bus interfaces 120 is 6 and the number of 1 bus interfaces 120 is 4, then the combination I and the combination II are not needed in the case of the scene 1 and the scene 2, and the number of 40 bus interfaces 120 is needed in the case of the scene 3, the user can disassemble the combination I and the combination II into the separate extension units 110 again, and reassemble all the extension units 110 into the combination III capable of providing the number of 42 bus interfaces 120, so that the extension units 110 of the scene 1 and the scene 2 can be reused without causing cost waste. Likewise, when scene 3 no longer has the requirement of 40 bus interfaces 120, the combination III can be split into different new combinations to be suitable for scenes with low requirements on other bus interfaces 120, without causing excessive redundancy on the number of bus interfaces 120, and compared with a bus recorder adopting fixed 40 bus interfaces 120, the user can flexibly adjust according to the required number of bus interfaces 120.
One of the at least two extension units 110 is configured as a master extension unit 110a and the remaining extension units 110 are configured as slave extension units 110b. In one embodiment, a user may preset an operation mode of the extension unit 110 through an external terminal, and if the extension unit 110 performs a function as a host, the operation mode of the extension unit 110 is preset as a host mode; if the slave unit 110 performs a function as a slave, the operation mode of the slave unit 110 is preset as a slave mode.
On the basis of the foregoing embodiment, it should be noted that, in addition to the twisted pair connection for communication between the extension units 110, a hardware connection may be further configured to facilitate the assembly of the extension units 110, where a first side of the extension unit 110 is provided with a first connection, and a second side of the extension unit 110 is provided with a second connection, where the first side and the second side are opposite sides, and the first connection is used to connect with a second connection of another extension unit 110, and the first connection may be a latch or a magnetic attraction, so that a user may conveniently assemble the required extension units 110 in hardware or may hardware-disassemble the existing combined bus data recorder 100 into the independent extension units 110.
In one embodiment, the on-board communication connection of master slave unit 110a and slave unit 110b is a UDP connection or a TCP connection. The user can select the type of the vehicle-mounted communication connection according to the data transmission requirements of different application scenes, for example, if the application scenes require the data to be transmitted efficiently and reliably, and large-scale retransmission caused by data errors or data loss is avoided, the user can select the type of the vehicle-mounted communication connection to be TCP connection; for another example, if the application scenario involves short data, and the receiving confirmation mechanism of TCP is not needed, the user may select the type of the vehicle communication connection to be a UDP connection.
In one embodiment, after master slave unit 110a establishes an on-board communication connection with slave unit 110b over an on-board twisted pair, all bus interfaces 120 are integrated into a continuous interface number. As shown in fig. 2, for example, the master slave unit 110a is a bus data recorder with the number of bus interfaces 120 being 8, the slave unit 110 bi is a bus data recorder with the number of bus interfaces 120 being 6, the slave unit 110 bi is a bus data recorder with the number of bus interfaces 120 being 4, when the corresponding bus interfaces 120 numbers of the master slave unit 110a are set to 0 to 7, the corresponding bus interfaces 120 numbers of the first slave unit 110b are set to 8 to 13, and the corresponding bus interfaces 120 numbers of the second slave unit 110b are set to 14 to 17, so that it is convenient to distinguish data received by different bus interfaces 120, and it is also convenient to perform abnormality investigation of the bus interfaces 120 of the corresponding slave unit 110 according to the bus interfaces 120 numbers in time when an abnormality occurs in a certain path of data.
The slave unit 110b is configured to send the bus data received from the corresponding bus data node to the master slave unit 110a through the on-board communication connection; the master-slave unit 110a is configured to integrate the bus data received from the slave unit 110b and the bus data received from the corresponding bus data node into single instrument data. Based on the foregoing embodiment, as shown in fig. 3, the master slave unit 110a is a CAN bus data recorder with 8 bus interfaces 120, the first slave unit 110b is a CAN bus data recorder with 6 bus interfaces 120, the second slave unit 110b is a CAN bus data recorder with 6 bus interfaces 120, wherein the bus data collected by the different bus interfaces 120 of the master slave unit 110a are numbered 0 to 7, the bus data collected by the different bus interfaces 120 of the first slave unit 110b are numbered 8 to 13, the bus data collected by the different bus interfaces 120 of the second slave unit 110b are numbered 14 to 17, the master slave unit 110a integrates the bus data sent by the first slave unit 110b and the second slave unit 110b and the bus data received by itself from the corresponding nodes into single instrument data, the single instrument data includes the bus data numbered 0 to 17, the master unit 110a is characterized as a combined bus data recorder 100, and the master unit 110a outputs the single instrument data.
As can be seen from the foregoing, in the embodiment of the present application, the combined bus data recorder 100 includes at least two slave units 110, where one of the at least two slave units 110 is configured as a master slave unit 110a, the other slave units 110 are configured as slave units 110b, the master slave unit 110a establishes a vehicle-mounted communication connection with the slave unit 110b through a vehicle-mounted twisted pair according to the configuration type of the slave unit 110, the slave unit 110b transmits bus data received from a corresponding bus data node to the master slave unit 110a through a vehicle-mounted communication connection, and the master slave unit 110a integrates the bus data received from the slave unit 110b and the bus data received from the corresponding bus data node into single instrument data; the method has the advantages that the extension units 110 for recording bus data are flexibly combined according to the number of bus data nodes of the automobile, the cost is low, the expansibility is high, the application scene is multiple, the single instrument data are obtained by integrating the data of the extension units 110, and the data transmission and the data processing are convenient.
Fig. 4 is a schematic diagram of another combined bus data recorder 100 according to an embodiment of the present application, and based on the combined bus data recorder 100 shown in fig. 1, as shown in fig. 4, the main extension unit 110a further includes a universal ethernet interface 140, and the universal ethernet interface 140 is used for characterizing the main extension unit 110a as a bus data recorder, and communicates with an off-board network through a wired network.
In one embodiment, the main extension unit 110a may be connected to the external network through the ethernet interface 140 in a wired manner, and when the main extension unit 110a integrates the received bus data into single instrument data, the main extension unit 110a outputs data corresponding to the data output by the combined bus data recorder 100 through the ethernet interface 140, so that the combined bus data recorder 100 may perform wired communication with the external network through the ethernet interface 140 of the main extension unit 110a, so that a relatively low cost communication channel may be provided compared to the case where a wireless communication module needs to be configured to communicate with the external network, or the communication with the external network may be maintained through the wired network when the wireless network communication is poor.
Fig. 5 is a schematic diagram of another combined bus data recorder 100 according to an embodiment of the present application, and based on the combined bus data recorder 100 shown in fig. 1, as shown in fig. 5, the main extension unit 110a further includes a mobile communication module 150 and/or a WiFi communication module 160, where the mobile communication module 150 and/or the WiFi communication module 160 are used for the main extension unit 110a to characterize the combined bus data recorder 100, and communicate with an external network through mobile network communication and/or WiFi communication.
In one embodiment, master extension unit 110a may include a mobile communication module 150, such as a 4G module or a 5G module, and may also include a WiFi communication module 160. The user can select the mobile communication module 150 or the WiFi communication module 160 according to network environments of different application scenarios, and after the main extension unit 110a integrates the received bus data into single instrument data, the single instrument data can be automatically uploaded to a server or a device terminal through the mobile communication module 150 or the WiFi communication module 160 for further data processing and analysis, so that when the wired network is limited by the cable distance, the wireless network can be conveniently utilized for data transmission.
Fig. 6 is a schematic diagram of another combined bus data recorder 100 according to an embodiment of the present application, and on the basis of the combined bus data recorder 100 shown in fig. 1, as shown in fig. 6, the main extension unit 110a further includes a general data interface 170, where the general data interface 170 is used to access a mobile storage device to obtain monomer instrument data. In one embodiment, the user may access the universal data interface 170 of the main extension unit 110a to the mobile storage device to obtain the monomer instrument data, for example, the user may access the SD card to the universal data interface 170 through the card reader and install the SD card in the main extension unit 110a, so that the main extension unit 110a may store the integrated monomer instrument data in the SD card, and when the combined bus data recorder 100 does not need to continue to operate, the user may copy the monomer instrument data out through the SD card; for another example, the user may access the mobile hard disk to the universal data interface 170, so that the master-slave unit 110a may store the integrated monomer instrument data in the mobile hard disk, and the user may utilize the monomer instrument data stored in the mobile hard disk for further processing and analysis when the combined bus data recorder 100 does not need to continue to operate.
On the basis of the foregoing embodiment, possible implementation manners further include that the master extension unit 110a is the same as or different from any one of the slave extension units 110b. For example, the master slave unit 110a selected by the user may include a plurality of in-vehicle ethernet interfaces 130, a general ethernet interface 140, a mobile communication module 150, a WiFi communication module 160, and a general data interface 170, such that the master slave unit 110a may be connected to a plurality of slave units 110b through the plurality of in-vehicle ethernet interfaces 130, and the master slave unit 110a may be characterized as a combined bus data recorder 100 that may support wired data transmission, wireless data transmission, and access to mobile storage devices, while the slave unit 110b may only include 1 in-vehicle ethernet interface 130 to connect to the master slave unit 110a without additional communication functions and data transmission channels with an off-vehicle network.
