Detailed Description
The application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings.
Example 1
Fig. 1 is a flow chart of a gateway upgrading method according to an embodiment of the present application, where the embodiment is applicable to a scenario of gateway upgrading, the method may be performed by an upgrading device of the gateway, and the device may be implemented in a hardware and/or software manner, and may be generally integrated in a vehicle-mounted gateway such as a computer with data computing capability.
As shown in fig. 1, the method of the present embodiment may include:
step 101, under the condition that the data routing function of the gateway needs to be upgraded, an upgrade request sent by the diagnostic apparatus is received, wherein the upgrade request comprises a routing configuration file.
It should be noted that, the diagnostic apparatus is generally a device capable of diagnosing whether there is currently an updated version of program code, and can determine whether there is an updated version of program code according to the previous updated version and the latest program version. Once the new version exists, an upgrade request is sent to the gateway controller, the upgrade request including the routing configuration file.
Referring to fig. 2 specifically, fig. 2 is a schematic diagram of gateway upgrade provided in the first embodiment of the present application, as shown in fig. 2, when a gateway data routing function needs to be upgraded, a diagnostic apparatus sends an upgrade request to a gateway controller through a diagnostic CAN bus, where the upgrade request includes a routing cfg file, that is, a routing configuration file, and the routing configuration file includes routing configuration data.
In addition, for gateway data security, after receiving the upgrade request and before upgrading, the gateway controller needs to authenticate the diagnostic apparatus sending the upgrade request, and the process of authenticating the diagnostic apparatus in this embodiment may refer to fig. 3, and fig. 3 is a schematic flow chart of authenticating the diagnostic apparatus according to the first embodiment of the present application.
As shown in fig. 3, after the receiving the upgrade request sent by the diagnostic apparatus and before the upgrading the route configuration data in the second storage space based on the route configuration file, the method may further include:
step 301, generating an authentication random number, and feeding back the authentication random number to the diagnostic apparatus, so that the diagnostic apparatus generates a first authentication value based on the authentication random number and a first key stored in the diagnostic apparatus.
In this step, after receiving the upgrade request initiated by the diagnostic apparatus, the gateway controller sends an authentication request to the diagnostic apparatus, where the authentication request may have a four-digit authentication random number, which may be 1053, for example.
The diagnostic instrument calculates an authentication value based on the received authentication random number and the internally stored secret key, and feeds back the obtained first authentication value to the gateway controller. In this embodiment, the calculation method includes, but is not limited to, shifting first and then AND operation. It should be noted that, the shift manner may be predetermined, and will not be described herein.
Step 302, receiving a first authentication value fed back by the diagnostic apparatus, and generating a second authentication value based on the authentication random number and a second key stored in the gateway.
In this step, optionally, if the gateway controller still does not receive the authentication value after exceeding the set time, the gateway controller resends the authentication request, and if the number of times continuously exceeds the set number of times, the authentication request is not responded, the authentication is considered to be failed, and the upgrading is ended. For example, the set time may be 5 seconds, and the set number of times may be 3.
If the gateway controller successfully receives the first authentication value fed back by the diagnostic instrument, the gateway controller generates a second authentication value based on the authentication random number and a secret key stored in the gateway. It should be noted that, the algorithm based on which the gateway controller generates the second authentication value may refer to the algorithm of calculating the first authentication value by the diagnostic apparatus, if the diagnostic apparatus can successfully authenticate, the algorithm of the first authentication value and the second authentication value are generally identical, and the first key and the second key are also identical.
Specifically, when the second authentication value is generated, the authentication random number and the second key stored in the gateway may be input into a preset encryption algorithm, and the second authentication value output by the preset encryption algorithm may be obtained.
In this step, the preset encryption algorithm may be, but is not limited to, performing an and operation after the shift. Of course, the calculation of the first authentication value may equally be based on the preset encryption algorithm.
And step 303, authenticating the diagnostic apparatus based on the first authentication value and the second authentication value, and executing the step of upgrading the route configuration data in the second storage space based on the route configuration file if authentication is successful.
In this step, if the first authentication value and the second authentication value are the same, authentication is successful. At this point, the following step 102 may continue.
Step 102, upgrading the route configuration data in the second storage space based on the route configuration file.
The ROM of the gateway is provided with a first storage space and a second storage space, the first storage space stores routing program codes, the second storage space stores routing configuration data, and when the gateway performs data routing based on the routing program codes, the gateway realizes the data routing process by calling the routing configuration data from the second storage space.
The ROM, also called read-only memory, usually operates in a non-destructive read-out manner, and only information which cannot be written in can be read out. The information is fixed once written, and even if the power supply is turned off, the information is not lost, so the information is also called a fixed memory.
In this embodiment, a first storage space and a second storage space may be set in the ROM to store different data respectively, so that the first storage space stores routing program codes, i.e. Code codes, and the second storage space stores routing configuration data, i.e. routing cfg data, including current routing configuration and backup routing configuration.
Referring specifically to fig. 4, fig. 4 is a block diagram of a data storage structure according to a first embodiment of the present application. As shown in fig. 4, the first storage space may be a code segment and the second storage space may be a routing cfg data segment.
In this step, the second storage space may further be provided with a first storage subspace, a second storage subspace, and a third storage subspace. As shown in fig. 4, the Select header is a first storage subspace, cfgA is a second storage subspace, and cfgB is a third storage subspace. The first storage subspace may be used to store spatial information of the second storage subspace and the third storage subspace, and information such as data update time.
In this step, referring to fig. 5, fig. 5 is a schematic flow chart of a process of upgrading the routing configuration data in the second storage space based on the routing configuration file according to the first embodiment of the present application.
As shown in fig. 5, the method for upgrading the routing configuration data in the second storage space based on the routing configuration file according to this embodiment may include:
step 501, space information corresponding to routing configuration data to be called is called from the first storage subspace.
Specifically, the routing configuration data currently required to be invoked refers to data used by the current gateway for data routing. The space information corresponding to the routing configuration data to be called currently refers to a storage position of data used by the current gateway for data routing, and the storage position can be represented by a space identifier, and can be a second storage subspace or a third storage subspace. The space information comprises space size information, space identification and the like of the subspace. The spatial information obtained in this step may include a spatial identifier.
For example, if the data used by the current gateway for data routing is stored in the second storage subspace, the space corresponding to the current routing configuration data to be called, which is called from the first storage subspace in this step, is identified as: the spatial identification of the second storage subspace.
Step 502, determining a target storage subspace which is not used currently based on the space information, wherein the target storage subspace is the second storage subspace or the third storage subspace.
In this step, based on the space identifier of the data used by the current gateway for data routing acquired in the above step, a currently unused subspace is selected as a target storage subspace, where the target storage subspace is the storage space of the routing configuration file required by the current upgrade.
For example, if it is identified that the space corresponding to the routing configuration data that is called currently and is required to be called and called from the first storage subspace is identified as the second storage subspace, the third storage subspace is selected as the target storage subspace.
Step 503, storing the route configuration data in the route configuration file in the target storage subspace in an overlaying manner, so as to finish upgrading the route configuration data in the second storage space.
In this step, the route configuration file required by the current upgrade is transmitted and stored in the target storage subspace, so that the route configuration data after the current upgrade is directly called from the target storage subspace when the data routing is performed subsequently.
In addition, in the upgrading process, a situation that the subspace cannot meet the space required by the routing configuration file may be encountered, so that the embodiment may further expand the target storage subspace, and particularly refer to fig. 6, and fig. 6 is a schematic flow chart for expanding the target storage subspace according to the first embodiment of the present application.
As shown in fig. 6, after the determining the currently unused target storage subspace based on the space information and before the storing the route configuration data in the route configuration file in the target storage subspace in an overlaying manner, the method for upgrading the route configuration data in the second storage space based on the route configuration file may further include:
step 601, obtaining space size information of the target storage subspace and space occupation size information of the routing configuration file.
In this step, the space size information of the target storage subspace and the space occupation size information of the routing configuration file may be retrieved from the first storage subspace.
Step 602, expanding the target storage subspace if the space size information and the space occupation size information do not meet a preset condition.
In this step, the preset condition means that the space size of the target storage subspace is larger than the space occupation size of the routing configuration file. When the space size of the target storage subspace is smaller than or equal to the space occupation size of the routing configuration file, the space size information and the space occupation size information are indicated to not meet the preset condition, and at the moment, the space expansion is required to be carried out on the target storage subspace until the space size of the target storage subspace is larger than or equal to the space occupation size of the routing configuration file.
Specifically, the space size information to be expanded can be calculated according to the space size information of the target storage subspace and the space occupation size information of the routing configuration file, then the space to be expanded corresponding to the space size information to be expanded is cut out from the blank storage space of the ROM, and finally the space to be expanded is merged into the target storage subspace.
And step 603, executing the step of storing the route configuration data in the route configuration file in an overlaying manner in the target storage subspace if the space size information and the space occupation size information meet preset conditions.
In this step, the size of the target storage subspace is larger than the size of the routing configuration file, that is, the target storage subspace can be ensured to store the routing configuration file to meet the preset condition. At this time, step 503 is executed.
Step 103, setting the updated route configuration data as the route configuration data required to be called when the gateway performs data routing based on the route program code. In this step, the space information in the first storage subspace may be updated to a space identifier corresponding to the target storage subspace, so that the gateway performs data routing based on the routing program code, and invokes the routing configuration data in the target storage subspace based on the space identifier.
In this step, updating the space information in the first storage subspace to the space identifier corresponding to the target storage subspace refers to updating the space identifier corresponding to the data used by the current gateway for data routing stored in the first storage subspace to the space identifier corresponding to the target storage subspace. After the space identifier corresponding to the data used by the current gateway for data routing stored in the first storage subspace is updated to the space identifier corresponding to the target storage subspace, the network management controller is restarted, and the updated routing configuration data can be used for data routing.
For example, if the space identifier corresponding to the route configuration data to be called currently stored in the first storage subspace is the space identifier of the second storage subspace and the target storage subspace is the third storage subspace, the space identifier corresponding to the route configuration data to be called currently stored in the first storage subspace is updated from the space identifier of the second storage subspace to the space identifier of the third storage subspace.
The embodiment also provides a data routing method of the gateway, which is applicable to a data routing scene of the gateway, and fig. 7 is a flow chart of the data routing method of the gateway provided by the first embodiment of the application.
As shown in fig. 7, the data routing method of the gateway provided in this embodiment may include:
step 701, in case of receiving a data routing request carrying a routing type, retrieving spatial information from the second storage space.
In this step, when the network management controller receives the data routing request, the space identifier corresponding to the routing configuration data to be called is called from the first storage subspace in the second storage space. Illustratively, a third storage subspace.
Step 702, retrieving target route configuration data corresponding to the route type from a target storage subspace identified by the space information in the second storage space.
In this step, a corresponding target storage subspace is found according to the space identifier obtained in step 701, and the routing configuration data of the current required type is retrieved from the target storage subspace.
Step 703, completing the data routing of the gateway based on the target routing configuration data.
In this step, the data routing of the gateway can be completed based on the routing configuration data retrieved in step 702.
In this embodiment, an upgrade request sent by a diagnostic apparatus is received under a condition that a data routing function of a gateway needs to be upgraded, where the upgrade request includes a routing configuration file; upgrading the route configuration data in the second storage space based on the route configuration file; setting the updated route configuration data as the route configuration data required to be called when the gateway carries out data routing based on the route program codes; under the condition of receiving a data routing request carrying a routing type, space information is called from a second storage space; retrieving target route configuration data corresponding to the route type from a target storage subspace identified by the space information in the second storage space; and finishing the data routing of the gateway based on the target routing configuration data, and realizing the upgrading of the gateway routing configuration data and the data routing after the upgrading. Therefore, the scheme of the application only needs to upgrade the route configuration data of the gateway, and does not need to upgrade all programs of the gateway, thereby greatly saving network resources and time required by upgrade and avoiding risks caused by upgrade interruption.
