Method and system for setting rope projectile working authority

Abstract

The invention provides a rope missile working authority setting method and system. The method comprises the steps: obtaining an unlocking secret key based on a pre-stored serial number of a micro-control unit carried by a rope missile, and obtaining a ciphertext based on a predetermined encryption algorithm, a preset password table, and the serial number; and determining the working authority of the rope missile based on the comparison result of the ciphertext and the unlocking secret key. The method is applied to the rope projectile assembly, the overall function of inquiring the unlocking secret key according to the serial number can be achieved, and the use requirement during design is completely met. Because the authority setting method provided by the invention is relatively simple, the authority setting method has very outstanding performance in the aspects of use safety and production efficiency.

Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation, and in particular relates to a method and system for setting the working authority of a rope elastic. Background technique [0002] In order to further improve the efficiency of setting-out operations and reduce the risk of manual setting-out operations, research is currently under way to explore the use of UAVs equipped with rope bombs and guide rope launch systems to launch rope bombs and pull the guide ropes through the pulley to achieve release. function of line work. [0003] However, the fired rope bomb has a weight of about 130 grams and a muzzle velocity of about 10-20 m / s, and has a certain kinetic energy. If it is not used properly, it may cause certain safety hazards. In order to avoid the illegal use of rope bullets and further reduce potential safety hazards, the technology of intelligent key distribution management can be used to control the launch aut...

Problems solved by technology

[0004] At present, permission control technologies that are applied to devices with low computing performance and can achieve certain encryption effects, short ciphertext length, low computing time complexity, easy input for users, and easy control for administrators have not yet been discovered.

[0005] Although algorithms with higher encryption strength can be used as encryption methods, most of these algorithms have high time complexity, and cannot achieve better operating results on slower single-chip microcomputer systems.
