Implementation method for security sharing switching of multiple printing devices based on optical isolation

Abstract

The invention discloses an optical isolation-based multi-printing equipment security sharing switching implementation method, which comprises the following steps of: constructing sharing printing switching equipment consisting of an input module, a task scheduler module and an output module, and carrying out optical unidirectional transmission on data among the input module, the task scheduler module and the output module, physical isolation of the circuit is realized; the input modules are directly connected with the computer through bidirectional data lines, the number of the input modules is larger than or equal to one, the input modules are physically isolated from one another, and each input module is provided with a one-way light emitting device. The input module simulates the input module into virtual printer equipment through a software algorithm according to data interaction behaviors of an entity printer, and realizes normal connection and data interaction with a computer; and the virtual paper data are analyzed into virtual paper data through a software algorithm, and are issued to the task scheduler module through the one-way light emitting device for subsequent processing. According to the invention, the problems of low utilization rate of printing equipment and equipment safety in a multi-network environment are solved.

Description

technical field [0001] The invention relates to the field of printing devices, in particular to a method for realizing safe sharing switching of multiple printing devices based on optical isolation. Background technique [0002] In today's complex network environment, in order to protect their internal data, many enterprises or organizations usually divide their internal computers into multiple independent network environments, and no matter what kind of network environment there is a demand for external printouts. If each local area network is equipped with a printing device, although the contradiction between network division and printing coexistence can be solved, there are often other problems that cannot be avoided. [0003] For example: 1. In some networks, there are fewer printing tasks, resulting in idle printing devices, while in some networks, there are many printing device tasks, resulting in insufficient printing devices; Redundant preparation; and other various...
