This invention discloses a plug-and-play modular rope-driven robotic arm resistant to stress abrupt changes, comprising a movable arm segment and a drive mechanism. The movable arm segment can be used in two ways: as a single application and as a whole application formed by quick-assembly and disassembly connection of multiple movable arm segments. The movable arm segment is equipped with a rope drive mechanism for controlling the rotation of the movable arm segment, and both ends of the control rope of the rope drive mechanism are equipped with main quick-assembly and disassembly connectors. The drive mechanism includes Bowden lines and drive ropes that can control the extension and retraction states of both ends. One end of the Bowden line is equipped with a telescopic section that can adaptively extend and retract, and the telescopic section is connected to the drive mechanism. Both ends of the drive rope pass through the two Bowden lines and are connected to auxiliary quick-assembly and disassembly connectors, which are quickly assembled and disassembled with the main quick-assembly and disassembled connectors. By adopting this solution, the problem that the existing technology cannot simultaneously achieve the convenience of "plug and play" and the stability of "resistance to stress abrupt changes" can be solved.

The application relates to the computer technical field, in particular to a security permission file analysis method and device, a vehicle and a storage medium. The method comprises the following steps: obtaining a to-be-analyzed security permission file; decrypting the to-be-analyzed security permission file, and calculating a first hash value and a second hash value according to a decryption result; if the first hash value is the same as the second hash value, determining that the to-be-analyzed security permission file is a legal permission file; otherwise, determining that the to-be-analyzed security permission file is an illegal permission file. Therefore, the legal permission file can be directly used to control multiple application software to jointly realize the same function, the problem that the traditional single application software permission file configuration cannot meet the permission information distribution for multiple application software at the same time is solved, the unified definition of the functions of multiple application software of the whole vehicle is realized, and the user experience is improved.

A data processing method, apparatus, device, storage medium, and computer program product are disclosed, applicable to various fields or scenarios such as cloud technology, artificial intelligence, blockchain, vehicle networking, smart transportation, and smart homes. The method includes: responding to an application authorization request for a target application sent by a device to be authorized; obtaining first identification information of a target product included in the device to be authorized; encrypting the first identification information using a symmetric key to obtain first ciphertext; encrypting the symmetric key using an authorization management public key to obtain second ciphertext; determining an application authorization code for the target application by the device to be authorized based on the first and second ciphertexts; and sending the application authorization code to the device to be authorized, so that the device to be authorized can determine whether it has permission to use the target application based on the application authorization code. Using embodiments of this application, a difficult-to-crack application authorization code can be generated, effectively preventing a single application authorization code from being used by multiple devices.

This invention discloses a heterogeneous desktop fusion method based on hardware and software collaboration, aiming to solve the problems of difficulty in balancing compatibility and performance, fragmented user experience, poor peripheral compatibility, and complex deployment when running Windows applications on domestic non-x86 platforms in the context of domestic IT innovation. This method connects the domestic system host and the x86 architecture Windows coprocessor unit through a dedicated USB bridge link, creating isolated virtual network and virtual USB dual channels in kernel mode. It uses a private protocol with single application window granularity for data transmission, and achieves hybrid rendering of remote windows and the local desktop through a kernel-level virtual display driver, while simultaneously realizing kernel-level transparent redirection of peripherals. This invention does not rely on the virtualization capabilities of domestic chips, achieving native-level compatibility with Windows applications, a seamless operating experience, and compatibility with all types of peripherals, significantly reducing the deployment and maintenance costs of domestic IT innovation transformation.
