Detailed Description
The technical solutions of the present invention are described in detail with reference to the drawings and the specific embodiments, and it should be understood that the embodiments and the specific technical features in the embodiments of the present invention are merely illustrative of the technical solutions of the present invention, and are not restrictive, and the embodiments and the specific technical features in the embodiments of the present invention may be combined with each other without conflict.
Fig. 1 is a flowchart of a CPU updating method according to an embodiment of the present invention, where the method includes:
s101, a current CPU receives an update instruction issued by a server;
s102, judging whether the updating instruction is a multi-CPU updating instruction or not;
if yes, go to step S103, otherwise go to step S104.
S103, entering the CPU for updating according to the updating instruction and the updating file, and sending an updating broadcast for indicating the online CPU to enter the CPU for updating;
and S104, updating according to the single CPU updating instruction, and sending a list updating broadcast for indicating the online CPU to delete the current CPU in the CPU list.
Specifically, in the embodiment of the present invention, before the updating step is performed, the local update file needs to be uploaded to a system directory of all CPUs of the device, and each CPU needs to maintain a CPU list, where the CPU list includes information of each CPU and a current operating state of the CPU, such as whether the CPU is online or offline.
In the embodiment of the present invention, the generation manner of the CPU list is: each CPU of the equipment sends the CPU information of the equipment by a broadcasting mode and receives the broadcasting information of other CPUs, so that each CPU can acquire the information of other CPUs, each CPU can further store a CPU list, and the CPU list can be updated in real time.
Furthermore, in the embodiment of the present invention, a file upload plug-in file is used in the update file upload process, so that the file can be asynchronously uploaded to each CPU specified path, and callback function processing is added, so that some things before upload can be processed, the progress of the upload process is displayed, and upload success and time-varying prompts are indicated.
In addition, in the embodiment of the present invention, the CPU list may also be displayed through a Web page, specifically as shown in fig. 2, the browser Web page front end provides a setting interface, executes an operation request through the JS script, then the browser Web page front end sends the request to the Web server, the Web server monitors the 80 port by default, points to the php back end, and then the php back end interprets the php script to generate the html page. This allows the CPU list to be displayed via a web page.
After the local update file is uploaded, a user may first select an update file to be updated through a browser, as shown in fig. 3, a Web display interface before updating of a CPU in the device is shown, and then the system uploads the update file selected by the user, as shown in fig. 4, a Web interface in an update file uploading process.
Then, the system verifies whether the update file is valid, if the update file is valid, the current update is further determined to be single-CPU update or multi-CPU update, if the update file is multi-CPU update, a multi-CPU update instruction is sent to the CPU in the current webpage, after the current CPU receives the multi-CPU update instruction, an update broadcast for instructing other online CPUs to enter CPU update is generated, and the current CPU enters a CPU update flow, as shown in fig. 5, a Web display interface in the CPU update process is shown, and after the update is successful, the system displays an update success interface shown in fig. 6.
And after receiving the updating broadcast, other online CPUs enter an updating process according to the updating broadcast and the updating file. By the method, the plurality of CPUs can simultaneously upload the update files to the designated directory based on the CPU list, and the plurality of CPUs can simultaneously enter the update process in an update broadcasting mode.
Further, if an abnormality occurs during updating of a certain CPU, the system may enter into the system to perform single CPU update on the abnormal CPU. That is, if the system updates a single CPU, the system issues a single CPU update instruction of the current CPU, updates according to the single CPU update instruction, and sends a list update broadcast for instructing the online CPU to delete the current CPU in the CPU list.
Further, in the embodiment of the present invention, after the CPU enters the update process, the CPU first determines whether the version number of the update file is greater than or equal to the current version number of the CPU, if so, the current CPU system is restarted, and enters the reset partition update, and if not, the update process is directly ended. Therefore, the CPU can be accurately updated, and the updating of the CPU can be timely and accurately carried out.
Corresponding to a CPU updating method in the embodiment of the present invention, a CPU updating system is further provided in the embodiment of the present invention, and as shown in fig. 7, the system is a schematic structural diagram of a CPU updating system in the embodiment of the present invention, and includes:
