Blockchain foundation-based three-dimensional (3D) printer for internet of things

Abstract

The invention relates to a blockchain foundation-based three-dimensional (3D) printer for internet of things. The 3D printer comprises printers, a communication network and control computers, wherein the plurality of printers are respectively connected with the control computers by the communication network, and all the printers are connected in parallel; the plurality of control computers respectively form at least one control local area network by means of the communication network; the printers are respectively provided with a blockchain control device; the blockchain control devices are respectively connected with the printers and the communication network; each blockchain control device comprises a bearing shell, a backup power, a central data processor, a metal oxide semiconductor (MOS) drive circuit, a data storage secure digital (SD) card, a data caching module, an address coding module and an inter-process communication (IPC) interface. The blockchain foundation-based 3D printer for the internet of things is simple in structure and flexible and convenient to use, can effectively meet the need of carrying out file printing operation from a long distance through the network on one hand, and can effectively improve the safety and reliability of file transfer and response during file printing on the other hand so as to prevent the phenomenon of data leakage.

Description

technical field [0001] The present invention relates to a network printer, specifically a blockchain-based Internet of Things 3D printer. Background technique [0002] With the development of computer network technology, in order to improve office efficiency and reduce office costs, multiple computers often share one or several printers located in different locations through the communication network to print documents. In actual use, it is found that Although this method effectively meets the needs of actual use, it needs to print files during the process of network transmission during operation, which leads to the leakage and loss of files, which leads to relatively poor security of file printing work. One problem, there is no professional countermeasure at present, which has seriously affected the work efficiency and safety of office work. Therefore, in view of this situation, it is urgent to develop an invented printer based on a network system to meet the needs of actua...
