The update data comprises a software package of an update version of a child node to be updated in the domain controller, and can also comprise software packages of update versions of all child nodes in the domain controller; it will be appreciated that the update data for child nodes within the domain controller will be sent to the master node as a whole.
The generation process of the update data is realized through a server, and specifically, a json file is generated through the server according to a software package of a child node to be updated in the domain controller; calculating the verification information of the software package of the child node to be updated; and generating updating data according to the json file, the verification information and the software package of the updating version of the child node to be updated.
The json file includes a software package name of a child node to be updated, an Identity Document (Identity Document), update version information of the software package, compatibility information of the software version, and the like. When the method is actually realized, a script can be generated through updating data set in a server, and a json file is automatically generated according to a software package of a child node to be updated in a domain controller; and finally, compressing the json file, the verification information and the software package of the updated version of the child node to be updated through the update data generation script to generate the update data. And transmitting the generated update data to the master node of the domain controller through the network.
Step S104, checking the updated data to determine whether the updated data passes the check;
in order to determine that data related to the child node in the updated data, such as a data summary (or a message summary), a name of the child node, and the like, are consistent with information preset in the domain controller, and the situation of update errors is avoided. Firstly, after receiving the updated data, the main node decompresses the updated data, then determines whether the decompressed data is consistent with the information of the child nodes in the domain controller according to the decompression result, if so, determines that the updated data passes the verification, and executes the step S106; if the data are inconsistent, the update data are determined not to pass the verification, and an update error can be reported to the server.
And step S106, if the verification is passed, respectively sending the software package of the updated version of each child node to the corresponding child node so as to update the software package of the current version of the child node.
Specifically, the software package of the update version of each child node may be simultaneously sent to the corresponding child node according to the identifier of the child node, and the child node updates the current software package through the received software package to finally obtain the updated software.
The embodiment of the invention provides a software updating method, which comprises the steps of receiving updating data of a software package aiming at child nodes, which is sent by a server; the updating data comprises: a software package of child node update version; checking the updated data to determine whether the updated data passes the check; and if the software package passes the verification, respectively sending the software package of the updated version of each child node to the corresponding child node so as to update the software package of the current version of the child node. In the mode, the main node of the domain controller is in communication connection with each sub-node respectively, and the software packages of all the sub-nodes to be updated can be updated according to the received update data, so that the software management of the server is simplified, and the development difficulty of the server is reduced.
The present embodiment also provides another software updating method, which is implemented on the basis of the foregoing embodiments, and the present embodiment mainly describes a specific implementation process of a step of performing verification processing on update data, determining whether the update data passes through the verification (implemented in step 202 and step 204), and a specific implementation process of a step of sending a software package of an update version of each node to a corresponding child node respectively, so as to update a software package of a current version of the child node (implemented in step 205). The method specifically comprises the following steps:
step 201, receiving update data of a software package aiming at a child node, which is sent by a server; wherein updating the data comprises: a software package of child node update version;
the update data further includes: checking information of the child node and a json file of the child node; the verification information is usually calculated by an information summarization algorithm through an update data generation script of the server, and may be represented as md5 sum. The json file is a configurable json file, and a json file configuration mode can be specifically used, so that the software updating process can be configured, and the method is also suitable for expansion and compatibility of subsequent updating functions. For example, adding a certain function can be realized by adding a certain field, but the use of the original software updating function is not influenced.
Step 202, decompressing the updated data to obtain the check information and json file of the child node;
and after receiving the updated data, the main node decompresses the updated data to obtain verification information and a json file, firstly verifies the verification information, and then verifies the json file.
Step 203, if the verification information of the child node is consistent with the preset verification information of the child node, verifying the json file of the child node, and judging whether the json file passes the verification;
step 204, if the verification information of the child node is inconsistent with the preset verification information of the child node, reporting error updating prompt information to a server;
the preset check information of the child node is usually generated in advance, is in the same mode as the check information generated by the server, and is obtained through an information summarization algorithm. During specific implementation, whether the verification information of the child node is consistent with the preset verification information of the child node or not can be compared, and if so, it is indicated that the received update data is not tampered. Then, in order to further determine whether the data content is wrong, the json file of the child node needs to be checked, and specifically, the json file of the received updated data and the related data of the child node of the domain controller may be compared to determine whether the json file passes the check.
If the update data is inconsistent with the update data, reporting error update prompt information to the server, wherein the error prompt information can be that the check information fails, so that the server regenerates the update data and then sends the update data to the master node.
One possible implementation:
(1) analyzing the json file to obtain a child node analysis result; the analysis result comprises the following steps: the method comprises the following steps of (1) identifying the software package of a child node, the identifier of the child node, and the update version information and compatibility information of the software package of the update version of the child node;
(2) determining a target child node from at least one child node according to the name of the software package of the child node and the identifier of the child node; acquiring current version information of a software package of a target child node;
(3) judging whether the updated version information is compatible with the current version information or not according to the compatibility information; if so, judging that the json file passes the verification; if not, reporting the prompt information of the update error to the server.
The json file comprises more related information of the child nodes, and the json file is firstly analyzed to obtain the names of the software packages of the child nodes, the identifiers of the child nodes, the update version information of the software packages of the update versions of the child nodes and the compatibility information. Then, according to the name of the software package of the child node and the identifier of the child node, a target child node which is the same as the name of the software package and the identifier of the child node is inquired from at least one child node included in the domain controller, and then the current version information of the software package of the target child node is inquired. The process master node can determine a plurality of corresponding target child nodes according to the names of the software packages of the child nodes and the identifiers of the child nodes, and simultaneously acquire the current version information of the software packages of the target child nodes.
In order to determine whether the current version information of the software package of the child node to be updated in the domain controller is inconsistent with the updated version information of the software package of the child node, and at the same time, whether the updated version information is compatible with the current version information. In the embodiment, whether the updated version information is compatible with the current version information is judged according to the compatibility information; if so, judging that the json file passes the verification, and indicating that the child node can be subjected to software updating; if not, reporting the prompt information of the update error to the server.
In step 205, if the verification is passed, the software package of the update version of each child node is transmitted to the corresponding child node in parallel in a multithreading manner, so that the child node updates the software package of the current version according to the received software package of the update version.
Specifically, the master node transmits the software package of the update version of each child node to the corresponding child node in parallel in a multithreading manner by using a plurality of communication manners, such as a CAN (Controller Area Network), an ethernet, an SPI (Serial Peripheral Interface), a master node local, and the like; and updating the software package of the current version by the child node according to the received software package of the updated version. In the method, the time consumption of upgrading can be effectively reduced by a parallel data transmission and upgrading method.
After the software package of each child node is updated, in order to further confirm that the software package of each child node is updated correctly, one possible implementation manner is as follows:
step 206, acquiring the version information of the updated software package of the child node;
step 207, if the version information of the updated software package of the child node is consistent with the update version information included in the update data, the software update operation is completed;
and step 208, reporting prompt information of update errors to the server if the version information of the updated software package of the child node is inconsistent with the update version information included in the update data.
And inquiring the version information of the updated software package of the child node in a query mode according to the node name and the node identifier of the child node. And comparing the version information of the software package of the updated child node with the updated version information included in the updated data, if the version information is consistent with the updated version information, finishing the updating of the software in the domain controller, and if the version information is inconsistent with the updated version information, reporting prompt information of update errors to the server, wherein the prompt information can include prompts of update version errors and the like, so that the server regenerates the updated data and sends the updated data to the master node.
In the mode, the updating of the software packages of all the child nodes in the domain can be managed through the updating data, the file structure in the data can be updated, and the software management complexity of the service is effectively reduced. The information of the software packages of all the child nodes is described through the json file, and the json file can be configured, so that the whole updating process can be configured, and the method is also suitable for expansion and compatibility of subsequent updating functions. For example, adding a certain function can be realized by adding a certain field, but the use of the original update function is not affected. And the time consumption of updating can be effectively reduced by upgrading each child node in the domain controller in a parallel mode.
Referring to a specific software updating method shown in fig. 2, an upgrade package corresponds to the update data, and first, a server generates a json file according to a software package of each child node by using an update data making script, where the file includes names of all node upgrade packages, node device IDs, software version information, compatibility information, and the like; and then, calculating md5sum of all the upgrade packages by using the update data making script, and compressing the software packages, json files and md5sum files of all the child nodes into a DCU upgrade package (corresponding to the update data). After the upgrade package is manufactured, the upgrade package is sent to a main node, the main node checks the upgrade package, firstly, the upgrade package is decompressed, and then whether the point comparison md5sum is consistent or not is judged; if the json files are consistent, the main node analyzes the json files and verifies the consistency of json file information of each upgrading packet domain; inquiring version information of each child node, and checking the compatibility of the upgrade package; and if the current version of the software package is consistent with the current version of the software package, performing data transmission and performing software flashing by the child node, namely sending the software package with the updated version to the child node so that the child node updates the current version.
And after the updating is finished, inquiring version information of the updated software package, if the version information is consistent with the preset updating version information, ending, and if the version information is inconsistent with the preset updating version information, reporting an error, namely sending error prompt information to the server.
