An anti-falling code scanning device based on the block chain technology

Abstract

The invention relates to an anti-falling code scanning device based on the block chain technology The device includes a main body and an acquisition screen. A processor and a memory are arranged in the main body, A fixing mechanism is arranged in the main body; the fixing mechanism includes a drive assembly, a movable plate and two stationary assemblies; the fixing assembly includes an air suctionrod, a suction cylinder, a piston, connecting tubes and suction cups; a shield mechanism is arranged on that main body; the shielding mechanism includes a rotating assembly, two transmission assemblies and two lifting assemblies; the rotating assembly includes a shield box, A rotating shaft, a shielding cloth and a connetion rod are arranged in the shielding box, The anti-falling code sweeping device based on block chain technology can cover the collecting screen when the code sweeping device is idle, thereby reducing the probability of misoperation and avoiding dust covering on the collecting screen. The code sweeping device and the desktop can be fixed by the fixing mechanism to prevent the code sweeping device from falling and being damaged.

Description

technical field [0001] The invention relates to a drop-proof code scanning device based on block chain technology. Background technique [0002] Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes intelligence composed of automated script codes. A new distributed infrastructure and computing method that uses contracts to program and manipulate data. It is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. [0003] Blockchain technology has a high degree of data security and is widely used. Among them is the scanning device. [0004] The code scanning devices in the prior art generally adopt the traditional data encryption method, which is easy to cause data loss. Moreover, when the ...

Problems solved by technology

[0004] The code scanning devices in the prior art generally adopt the traditional data encryption method, which is easy to cause data loss. Moreover, when the code scanning device in the prior art is placed on the desktop, there is no fixing device, and it is easy to be knocked down and fall to the ground The damage reduces the safety of the code scanning device. Not only that, the acquisition screen of the existing code scanning device is always in working condition, and it is easy to scan others, which increases the probability of misoperation and reduces the practicability of the code scanning device.
