Method, system, and device for external communication of industrial server and industrial server

Abstract

Embodiments of the invention disclose a method, a system and a device for external communication of an industrial server and the industrial server. The method comprises the following steps of: runningat least two real-time operating systems in the industrial server sequentially according to a preset time slice schedule, wherein the at least two real-time operating systems run on a same physical core; controlling the currently running real-time operating systems; reading corresponding collected data from a random access memory; performing operation processing on the collected data; and writingan obtained operation result into the random access memory. The collected data is the data acquired by a communication module from a remote device and written into the random access memory, and the communication module is independent of the at least two real-time operating systems. The technical solution of the method, the system, and the device for external communication of the industrial serverand the industrial server can improve the external communication efficiency of the industrial server.

Description

technical field [0001] The embodiments of the present invention relate to the field of industrial control, and in particular, to an external communication method, system, device and industrial server of an industrial server. Background technique [0002] With the continuous development of science and technology, industrial servers based on virtualization technology are widely used in the field of industrial control. [0003] An industrial server based on virtualization technology, that is, multiple controllers can run simultaneously in one industrial server, and different data analysis and control instruction sending operations can be performed between different controllers. At present, industrial servers based on virtualization technology generally use time slice round-robin training to schedule different real-time operating systems running on the same physical core. In each real-time operating system, the calculation work of PLC (Programmable Logic Controller, programmabl...

Problems solved by technology

For example, when the first real-time operating system finishes executing the PLC algorithm, when the real-time operating system is about to send a request message for the calculation result data to the remote device, if the preset timing period on the time slice expires, it will be switched to the first real-time operating system. If the two real-time operating systems are running, then the first real-time operating system can only wait until the other real-time operating systems have executed their own time slices, and then it will be the first real-time operating system to continue running, that is, it can continue to send The request message of the calculation result data delays the data transmission time of the first real-time operating system, which will reduce the external communication efficiency of the industrial server
