Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
In this embodiment, a routing configuration scheme of the present invention will be described by taking development of a vehicle-mounted gateway compliant with an Automotive Open Systems Architecture (AutoSAR) as an example.
For example, when a vehicle-mounted gateway conforming to the AutoSAR is developed, a routing table of the vehicle-mounted gateway is frequently updated along with changes of requirements, if hundreds of changes in the routing table require manual configuration and testing, a large amount of resources are occupied in time and labor cost, and a routing function of the vehicle-mounted gateway affects CAN (Controller Area Network) communication functions of all Electronic Control Units (ECUs) of a whole vehicle, and once an error occurs, the communication function of the whole vehicle is affected, so that the development progress of the whole vehicle is blocked. Therefore, how to rapidly and accurately configure the routing table in the vehicle-mounted gateway has a very important significance. In the development process, a routing configuration file of the vehicle-mounted gateway is generally generated based on a routing table, for example, data in the routing table is converted into a file in an arxml format and then converted into a routing configuration file in an xdm format by using a development tool provided by EB (Elektrobit) company, such as EB tresos studio and the like; and then writing the routing configuration file in the xdm format into the vehicle-mounted gateway through operations such as compiling and the like, and completing the routing configuration of the vehicle-mounted gateway. Obviously, in the route configuration process, the generation step of the route configuration file plays a key role in the whole route configuration.
Therefore, the route configuration scheme of the embodiment of the invention mainly improves the efficiency and the accuracy of the link of generating the configuration file, thereby improving the efficiency and the accuracy of the route configuration. Specifically, for the case that routing table paths (e.g., pduroutingpaths) need to be grouped when a routing configuration file is generated, the embodiment of the present invention constructs a grouping dictionary (pre-constructed or constructed in real time based on a routing table), and groups the routing table paths by using the grouping dictionary, so as to improve the efficiency and accuracy of routing configuration by improving the efficiency and accuracy of grouping. The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a route configuration method according to an embodiment of the present invention. Which comprises the following steps:
and step S10, acquiring a routing table.
In step S10, the obtained routing table may be, for example, an excel format file, which may be uploaded to the routing configuration apparatus by a developer (e.g., a series of tool sets for implementing routing configuration). In the routing table, a plurality of communication matrices capable of representing routing relationships are recorded, wherein each communication matrix is a row-N column matrix which records data such as where a message comes from and is going to. For example, the routing table is illustrated by taking table one as an example, and table one is a portion of the routing table showing a first row and a second row of the routing table.
Watch 1
As shown in table one, the routing table may include a plurality of data types, which are located in the first row (i.e., the header portion) of the routing table, and start from the second row, and are each specific communication matrix. It should be noted that the contents (e.g. the type of data included) in the routing table can be flexibly set by those skilled in the art according to the actual situation, and the table is only used as an example and is not a limitation to the embodiment of the present invention. In some embodiments, fewer fields or more fields than table one may be provided in the routing table. In addition, the routing table shown in table one is usually a standardized routing table, and in the development of the vehicle-mounted gateway, the types of the routing tables from different sources are often different, and at this time, the original routing table may be converted into the standardized routing table, so as to facilitate further processing in the embodiment of the present invention. Among other things, some conversion tools may be utilized to convert the original routing table into a standardized routing table to improve the efficiency of the conversion. In addition, in the conversion process, the conversion tools can detect, prompt or correct format problems, logic problems and the like in the original routing table, so that the problems or errors in the converted routing table are reduced, and the wrong routing relationship is prevented from being configured in the gateway.
And step S11, generating a routing table path and corresponding grouping conditions according to the routing table acquired in the step S10.
Each communication matrix in the routing table can generate a routing table path and a corresponding grouping condition correspondingly. In general, hundreds of communication matrices are often included in the routing table, so hundreds of routing table paths and corresponding packet conditions are generated accordingly in step S11.
In step S11, data is first extracted from the input routing table, for example, various types of data are extracted by classification (based on the data type shown in the header), and then a routing table path and corresponding packet conditions are generated based on the extracted data. The routing table path is used for representing a specific routing relation, such as where a signal comes from and where the signal comes from; based on the routing table path, the vehicle gateway can implement a routing function.
The format of the routing table path may be, for example:
"PduRRout-ingPath":"ASPath:/PduR/PduR/PduRRoutingTables/PduRRoutingTable/Can_name_name_ID_R/Can_name_name_ID_T_D"
as seen in this format, the routing table path includes: a receiver semaphore name (Can _ name _ name _ ID _ R) and a sender semaphore name (Can _ name _ name _ ID _ T). The Can represents the Can channel to which the receiving/sending signal belongs, the name represents the name of the receiving/sending signal, the name _ ID represents the identity of the receiving/sending signal, the R represents the receiving end, and the T represents the sending end. Through the routing relation represented by the signal name of the receiving end and the signal name of the sending end, the vehicle-mounted gateway can realize the routing function. In addition, the information related to the receiving end signal name and the sending end signal name is extracted from the routing table, namely information such as Can, name and name _ ID is extracted from each communication matrix in the routing table, then the receiving end signal name and the sending end signal name are respectively constructed according to the format, and then a routing table path is constructed according to the constructed receiving end signal name and the constructed sending end signal name.
The grouping condition may be flexibly set according to actual requirements, for example, in some requirements, the grouping condition includes: one or more of vehicle type, routing type, CAN channel, and exhaust emission standard. Wherein, the motorcycle type can divide into again: conventional vehicle models (e.g., fuel vehicles), PHEVs (plug-in hybrid vehicles), EVs (pure electric vehicles), and so on. The type of routing refers to, for example, whether the transmitted message is a diagnostic message or an application message. The CAN channel indicates from which CAN the onboard gateway sends the message, for example CAN6; the exhaust emission standard refers to the support situation of automobiles to the state V and the state VI, for example. For example, in a certain project, PHEV, EV, routing type, CAN channel and exhaust emission standard are required as grouping conditions, and for a certain communication matrix in the routing table, the generated grouping conditions may be, for example: < PHEV: y; n is EV; the routing type is as follows: diagnosing; a CAN channel: can6; GA/V/VI: V >.
And step S12, acquiring a grouping dictionary.
Wherein the packet dictionary comprises: the plurality of routing packets correspond to different packet conditions. By way of example, the pattern of the packet dictionary may be as follows:
routing packet 1: condition 1 1 Condition 2 1 823060, 8230n 1 ；
……
Routing packet n: condition 1 m Condition 2 m 823060, 8230min, condition n m 。
In other words, a routing packet is defined by the combination of all possible values of condition 1 to condition n, i.e. all possible combinations of packet conditions. In addition, the packet dictionary does not contain a routing table path. Wherein the condition 1 to the condition n are determined according to actual requirements. In some embodiments, conditions 1 through n comprise: vehicle type, route type, CAN channel and exhaust emission standard. In other embodiments, conditions 1 through n include vehicle type, route type, and CAN channel.
In some embodiments, the group dictionary may be generated and stored in advance, and step S12 specifically refers to obtaining a pre-stored group dictionary; for example, in some embodiments, a group dictionary for the requirement can be constructed in advance by a developer according to the requirement and stored in the system. In other embodiments, to increase the versatility of the present solution, the packet dictionary is generated from the retrieved routing tables. Specifically, the method comprises the following steps:
first, all packet-related data types (e.g., PHEV, EV, CAN channel, GA/V/VI) are extracted from the retrieved routing table. Which data types are related to the packet may be predefined, for example, in the row (i.e., the first row) of the header of the routing table, some types may be defined as related to the packet by adding a key; after the data in the row of the header is extracted, whether the data type corresponding to each column is related to the grouping or not can be determined according to whether each column contains a preset keyword or not; for example, if the data recorded in a column in the header is "packet-PHEV" and the packet is a predefined key, it can be determined from the packet that "PHEV" is the data type associated with the packet.
Then, a plurality of grouping conditions are generated according to the combination of the data types. After all packet-related data types are extracted, the data types are arranged according to a predetermined order (such as the size of the column number), and all possible packet conditions are generated based on the possible combinations of values of each data type, for example, if PHEV, EV, CAN channel and GA/V/VI are packet-related data types, all possible values thereof CAN be combined according to the order of PHEV, EV, CAN channel and GA/V/VI, thereby generating all possible packet conditions. Here, the order of the respective data types and the order of the respective conditions in the grouping conditions in step S11 need to be the same, so that the comparison is relatively easy in grouping.
Finally, all routing packets are defined by these packet conditions. That is, each packet condition represents a routed packet.
It should be noted that, when the packet dictionary is generated according to the routing table, the step S11 and the step S12 may be executed at the same time, or the step S11 may be executed first, or the step S12 may be executed first, which are not limited in this embodiment.
And step S13, grouping the routing table paths according to the grouping conditions in the step S11 and the grouping dictionary in the step S12.
When grouping is performed, step S13 may match the grouping condition obtained from each communication matrix with the grouping condition in the grouping dictionary, and when the same grouping condition is matched, the corresponding routing table path is divided into the grouping corresponding to the matched grouping condition; thus, the routing table paths with the same grouping condition can be divided into the same group.
And step S14, generating a route configuration file according to the grouping result. And
and S15, configuring the vehicle-mounted gateway according to the route configuration file generated in the S14.
In step S14, a route profile may be generated by updating a PduR (protocol data unit route) profile. For example, an empty PduR profile may be loaded and the routing table path added to the PduR profile as a result of the grouping.
In step S15, the routing configuration file may be compiled into a binary file, and then burned into a memory of the vehicle-mounted gateway to implement routing configuration.
In the embodiment, the routing table paths are grouped by using the grouping dictionary, so that the grouping efficiency and accuracy are improved, and the routing configuration efficiency and accuracy are further improved.
Fig. 2 is a schematic flow chart of another embodiment of the route configuration method of the present invention, which includes the following steps:
step S20, obtaining a routing table, for example, a file in xls format, where a lot of routing information is filled, and the routing table needs to be configured into the vehicular gateway product.
Step S21, extracting the required data from the routing table of step S21, where the data includes, for example: vehicle model, routing type, CAN channel, receive message name, send message name, etc. In general, the extracted data is primarily data related to packets and data related to generating routing table paths.
Step S32, generating available information conforming to EB tresos, and constructing a grouping dictionary. The information available in accordance with EB tress is, for example, a routing table path in accordance with EB tress requirements, and the routing table path is a field that can be directly used by the configuration file in the xdm format in the EB tool, and can be directly filled into the configuration file in the xdm format.
And step S23, grouping the routing table paths and storing the grouping result into a database.
Steps S24 and S25 update pdur.xdm with the result of the grouping.
And S26, generating a Pdu.xdm file and a related file (such as an application layer code file with a format of.c.h).
And S27, compiling the files generated in the step S26 together, and burning the files into the vehicle-mounted gateway, so as to realize the routing configuration of the vehicle-mounted gateway.
In the embodiment, routing configuration is mainly realized based on tools such as EB tress, and in the tools such as EB tress, a packet dictionary is introduced to realize fast and accurate routing grouping, and a routing configuration file is generated in a manner of updating pdur.
