The invention discloses a preset key activation method and system. The method comprises the steps that a preset key distribution mechanism distributes a preset key file 1 and an authentication key file 0 to first equipment and second equipment; the device authentication mechanism performs device identity authentication on the first device and the second device based on the authentication key file file0; according to the message that the identity authentication of the device is passed, the first device and the second device respectively execute an activation operation on the preset key file (file1); the first device authenticates the key data with the second device based on the data information of the preset key file file1; and the first device and the second device determine an available preset key file (file2) according to the message that the key authentication is passed. According to the method disclosed by the invention, before the terminal equipment enters a communication network for use, the key storage module of the preset key unit is in a black box state and an inaccessible state and is not interacted or connected with any unit, so that the possibility that bad users steal the preset key is avoided from the source.

The invention discloses a multi-device batch file transmission method and system based on an open source gap system, a terminal and a storage medium. The method comprises the following steps: providing a visual interface, receiving network identifiers of one or more target devices in various formats input by a user, analyzing the network identifiers, and generating an IP address list of the target devices to be connected; concurrently trying to establish an HDC connection with each target device and performing state verification, and dynamically screening and generating an operable device list according to a verification result; receiving configuration of a local file, a device end target path and a transmission option by a user; for each piece of target equipment in the operable equipment list, when an instruction that a user confirms to start batch transmission is detected, file transmission is executed concurrently, and transmission result verification is carried out; and after the transmission task is completed, summarizing the execution state of each target device, and generating a visual transmission report. According to the invention, one-key batch file transmission of the open-source gap equipment cluster is realized.

The application discloses a kind of about manufacturer YANG file atomic capability storage and rendering method, system, electronic equipment and storage medium. The above-mentioned method is reformed to manufacturer YANG file by tree-shaped modification algorithm, and the atomic capability is stored after reformation with tree structure. For the problem that cannot quickly respond to manufacturer YANG file iteration, this method forms an atomic capability template for different versions of YANG file, and the same version of YANG file appears thereafter can be quickly responded, effectively improve the rate of configuration to router switch exchange. The present application provides a data structure that can be understood by the front end, and renders the atomic capability structure relationship in the front end. The above-mentioned system includes: file analysis module, data processing module, data storage module and configuration issuing module;The system implements the corresponding method described above. The present application has the advantages of reducing the coupling degree of device configuration content, quickly responding to different versions of YANG file, device configuration issuing template supporting multiple scene variables and the like compared with the prior art.

This invention provides a method and system for implementing communication protocol conversion in an intelligent gateway, belonging to the field of industrial communication gateways. The method includes: loading the corresponding communication protocol packing / unpacking program and registering the corresponding communication protocol packing / unpacking interface according to the communication protocols of each device; loading the device variable definition file and the device communication instance definition file for each device; wherein the device variable definition file and the device communication instance definition file are both defined using a preset dynamic programming language; and executing the communication instance for each device based on the device variable definition file, the device communication instance definition file, and the communication protocol packing / unpacking program to perform data transmission between the devices. This reduces the coupling between various modules of the program, reduces the complexity of hard coding, and thus improves the reusability of each functional module of the program, making the communication gateway program more versatile.

The embodiment of the present disclosure provides a cloud mobile phone-based remote real-time streaming screenshot method, and belongs to the technical field of data processing. Specifically, a memory file device logically bound to a cloud mobile phone instance is created on a host computer, and a virtual file device driver module is configured inside the cloud mobile phone instance. When a proxy program on the host computer receives a screen data request from a remote client, a read operation is performed on the memory file device. When the read operation is intercepted by the virtual file device driver module, the virtual file device driver module controls a screenshot module inside the cloud mobile phone instance to capture original pixel data of a current frame screen. The virtual file device driver module directly writes the original pixel data in the form of a byte stream into a buffer of the memory file device. The proxy program reads the byte stream from the memory file device in a streaming manner, encodes the byte stream, and then transmits the byte stream to the remote client through a network. Through the scheme of the present disclosure, the screenshot efficiency and real-time performance are improved.
