Description

[Technical Field]

[0001] The present invention relates to the technical field of automobile bus adapters, and more particularly to a method for arranging a mapping table in a mapping management device, a method for binding and arranging a bus adapter and a channel, a bus adapter connection system, and a bus adapter. [Background technology]

[0002] An automotive bus adapter consists of a device with a USB interface on one end and one or more external automotive bus interfaces (such as CAN bus, LIN bus, FlexRay bus, or automotive Ethernet) on the other end. There are many types of conventional automotive bus adapters, originating from different manufacturers. To monitor the automotive bus, the automotive bus adapter must be integrated with a host application developed by the user. The host application must always connect multiple automotive bus adapters to access multiple buses simultaneously. During the application process, conventional technical solutions usually hard-code the automotive bus adapters that need to be connected into the software.

[0003] During the application process, the prior art solutions hard-code the required car bus adapter into the software, which brings about two problems. First, replacing automotive bus adapter A with automotive bus adapter B requires a simultaneous software change, replacing the connection code of automotive bus adapter A with the connection code of automotive bus adapter B, which requires additional software modification time. If automotive bus adapter B is later replaced with automotive bus adapter A, the software must be modified again. Some users try to support automotive bus adapter A and automotive bus adapter B simultaneously and complete the adapter switching through configuration, but this method also causes the problem of incompatibility with automotive bus adapter C. Next, when two identical car bus adapters A and B are connected at the same time, such as when A is inserted into the computer first and then B, or when B is inserted into the computer first and then A, it is difficult for the software to distinguish between A and B. Even if a user reads the serial numbers of the car bus adapters to bind A and B, it is difficult to automatically identify the bus adapter after A is replaced with C in the subsequent application process.

[0004] Such problems must ultimately be resolved by correcting the software, which increases the amount of work and reduces the reliability of the software.

[0021] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. It is clear that the described embodiments are only some embodiments of the present invention, and are not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without performing creative work fall within the scope of protection of the present invention.

[0022] Example 1 FIG. 1 is a flowchart of a method for binding and arranging a bus adapter and a channel according to the present invention.

[0023] As shown in Figure 1, this embodiment 1 provides a method for binding and configuring bus adapters and channels, including: configuring a mapping table in a mapping management device, associating logical channels with corresponding hardware channels through the mapping table, and connecting the logical channels to the corresponding hardware channels for data communication, thereby realizing a general architecture for an application to access bus adapter resources. An application using this architecture can arbitrarily set the bus adapter model number and hardware channel it needs to connect to, and the mapping relationship is immediately effective after each configuration change, eliminating the need to modify the user's software, thereby improving application development efficiency and reducing the possibility of errors.

[0024] FIG. 2 is a schematic diagram of the binding and arrangement of bus adapters and channels according to the present invention.

[0025] As shown in FIG. 2, in this embodiment, the method for configuring the mapping table in the mapping management device includes the following: The mapping management device is responsible for associating each logical channel with a hardware channel of the bus adapter, and each association is realized by a mapping table written in the mapping management device. Each mapping table includes six information fields, and all of these mapping tables together form a mapping network between potential applications and potential bus adapters in the computer. Mapping tables in the mapping management device can be added or deleted at will by the user, and the six information fields in the mapping table can be arbitrarily configured. The six information fields in the mapping table include application name, channel type, logical channel index, hardware type, hardware index, and hardware channel index. For the automotive bus types supported by an application, each type has one or more logical channels, and the number and type of logical channels are configured by the user (e.g., the user can configure the number and type of logical channels through corresponding software). Take the CAN bus supported by application A as an example, which has three logical channels, and the mapping targets corresponding to each logical channel are managed by the mapping management device. The mapping table associates each logical channel of the mapping management device with a hardware channel of the bus adapter, realizing a general architecture for an application to access bus adapter resources. An application using this architecture can arbitrarily configure the model number and hardware channel of the bus adapter it needs to connect to. By simply modifying the software configuration, it is possible to deal with issues such as replacing the car bus adapter and access priority to the computer without modifying the software, avoiding additional development investment and ensuring software reliability.

[0026] In this embodiment, the application name is the string name of the application that uses the mapping management device, for example, application A. The channel type is the channel type of the logical channel for which the mapping management device is responsible for mapping. For example, logical channel A of application A is a CAN bus type. The logical channel index is the logical channel resource number of the application, which increases from smallest to largest. The logical channel index is the number assigned to the logical channel, and the index value is the numerical sequence, which increases from smallest to largest. For example, if there are three logical channels, their indexes are 0, 1, and 2, respectively. The hardware type is the manufacturer type of the corresponding bus adapter and the model number of the bus adapter under the manufacturer. The hardware index is a number used to distinguish similar hardware after the corresponding bus adapter is inserted into a computer. This number is dynamically adjusted in the computer based on the sorting method of the bus adapter sequence numbers. The hardware channel index is the number of a similar hardware channel carried within the corresponding bus adapter, which is preset for the same bus adapter. For example, hardware channel A of bus adapter A.

[0027] FIG. 3 is a schematic diagram of a bus adapter hardware index sorting method according to the present invention.

[0028] As shown in FIG. 3, in this embodiment, the hardware index is obtained by sorting the sequence numbers of the bus adapters in ascending order. After sorting the sequence numbers (SN) of each bus adapter in ascending order, the bus adapter with the smallest sequence number has the lowest hardware index. The hardware index is obtained by sorting the sequence numbers of the bus adapters in ascending order, using string matching. The sequence numbers of the bus adapters are read and obtained using the API interface provided by the bus adapter manufacturer. For example, suppose N bus adapters of the same type and manufacturer are inserted into a computer, each with a different serial number (SN). After sorting the serial numbers in ascending order, the bus adapter with the smallest serial number (SN=000001) has the lowest hardware index, and the bus adapter with the second smallest serial number (SN=000123) has the second lowest hardware index.

[0029] In this embodiment, the method for associating logical channels with corresponding hardware channels according to the mapping table includes the following: Associating each logical channel with a hardware channel of a corresponding bus adapter according to the mapping table.

[0030] In this embodiment, the method for connecting the logical channels to corresponding hardware channels for data communication includes the following: When an application is connected to a bus adapter, all supported bus adapters inserted in the computer are scanned, and a mapping table associated with the application is searched for in all mapping tables included in the mapping management device based on the application name. For each logical channel associated with the application, a search is performed to determine whether corresponding hardware exists based on the hardware type, hardware index, and hardware channel index in the mapping table. If a corresponding hardware exists, the corresponding bus adapter is initialized, and the data transmission / reception function of the logical channel is connected to the hardware channel of the corresponding bus adapter, thereby realizing data communication between the application logical channel and the corresponding bus. If no corresponding hardware is found to exist in the connection process, the connection fails. This realizes a general architecture for an application to access bus adapter resources. An application using this architecture can arbitrarily set the bus adapter model number and hardware channel it needs to connect to. After each configuration change, the mapping relationship is immediately valid, eliminating the need to modify the user's software, thereby improving application development efficiency and reducing the possibility of errors. At the same time, it also enables a user's application to indiscriminately access channel resources of automotive bus adapters manufactured by different manufacturers. If the bus adapter or hardware channel needs to be changed during the application process, only the configuration needs to be changed without modifying the software. By choosing this method when developing applications, users can achieve more in less time.

[0031] Example 2 FIG. 4 is a block diagram showing the principle of the binding and allocation system between bus adapters and channels according to the present invention.

[0032] As shown in FIG. 4 , based on the first embodiment, the second embodiment further provides a bus adapter and channel binding and configuration system, including: a mapping table configuration module for configuring a mapping table in a mapping management device; an association module for associating logical channels with corresponding hardware channels through the mapping table; and a connection module for connecting logical channels to corresponding hardware channels for data communication. This realizes a general architecture for an application to access bus adapter resources. An application using this architecture can arbitrarily set the bus adapter model and hardware channel it needs to connect to. After each configuration change, the mapping relationship is immediately valid, eliminating the need to modify the user's software, thereby improving application development efficiency and reducing the possibility of errors. At the same time, this allows the user's application to indiscriminately access channel resources of automotive bus adapters produced by different manufacturers. If the bus adapter or hardware channel needs to be changed during the application process, only the configuration needs to be changed without modifying the software. By choosing this method when developing applications, users can achieve more results in less time.

[0033] In this embodiment, the method in which the mapping table arrangement module arranges the mapping table of the mapping management device, the association module associates the logical channel with the corresponding hardware channel through the mapping table, and the connection module connects the logical channel with the corresponding hardware channel to perform data communication has been described in detail in the first embodiment, so the description will be omitted in this embodiment.

[0034] Example 3 Based on the first embodiment, the third embodiment further provides a mapping management device. The mapping management device is adapted to associate logical channels with hardware channels. This realizes a general architecture for an application to access bus adapter resources. An application using this architecture can arbitrarily set the bus adapter model number and hardware channel it needs to connect to. After each configuration change, the mapping relationship is immediately effective, eliminating the need for user software modification, thereby improving application development efficiency and reducing the possibility of errors.

[0035] In this embodiment, the method of associating the logical channels with the hardware channels employs the method of binding and arranging the bus adapters with the channels in the first embodiment.

[0036] Example 4 FIG. 5 is a block diagram showing the principle of a bus adapter connection system according to the present invention.

[0037] As shown in Figure 5, based on the third embodiment, the fourth embodiment further provides a bus adapter connection system, which includes an application module (a module on which an application is installed), a mapping management device, and a bus adapter. The mapping management device is adapted to associate and connect each logical channel in the application module with a hardware channel of the bus adapter for data communication. This allows a user's application to indiscriminately access the channel resources of automotive bus adapters manufactured by different manufacturers. If the bus adapter or hardware channel is changed during the application process, only the configuration needs to be changed without modifying the software. Users can choose this method when developing applications, achieving more results in less time.

[0038] In this embodiment, the application module can have a single or multiple logical channels, and the bus adapter can have a single or multiple hardware channels.

[0039] In this embodiment, the application module, mapping management device, and bus adapter are adapted to perform data communication by associating each logical channel with a hardware channel of the bus adapter using the binding and arrangement method between the bus adapter and the channel in embodiment 1, and then connecting them.

[0040] In summary, the present invention realizes a general architecture for an application to access bus adapter resources by configuring a mapping table in a mapping management device, associating logical channels with corresponding hardware channels through the mapping table, and connecting the logical channels to the corresponding hardware channels for data communication. An application using this architecture can arbitrarily set the bus adapter model number and hardware channel it needs to connect to, and the mapping relationship is immediately effective after each configuration change, eliminating the need for user software modifications, thereby improving application development efficiency and reducing the possibility of errors.
