Industrial personal computer with multi-image shared memory

Abstract

The invention discloses an industrial personal computer with a multi-image shared memory. The industrial personal computer mainly comprises a display apparatus, a display and control processing module, a display interface module, an input interface module, and a data storage module, wherein the display and control processing module comprises at least two function sub-modules and processes an input signal sent by the input interface module. Each function sub-module generates a corresponding display operation image and the corresponding display operation image is displayed on the display apparatus; and image data of display regions such as background image display regions and the like of different display operation images is stored by adopting the shared memory, so that the storage space for displaying the image data required by the images is greatly saved; the industrial personal computer disclosed by the invention does not contain complex hardware such as a CPU, a display card and the like, and complex software such as an operation system, display operation image software and the like in a running process; a system is simple, low in cost and easy to fully test and verify; and the industrial personal computer has the characteristics of very high function security and information security.

Description

technical field [0001] The invention relates to the field of industrial computers, in particular to an industrial computer with multi-picture shared memory which uses a hardware description language to describe and realize logical functions. Background technique [0002] In the aerospace, high-speed rail, banking, military, petrochemical, medical and other fields, the failure of the display and control system may cause heavy casualties or heavy losses of device property. Virus attacks such as "Stuxnet", "Flame" and "Poison Zone" have caused serious losses to the industry. American hackers once invaded the ATM network of Citibank, causing Citigroup to suffer losses of at least 2 million US dollars. The display and control system described here is the industrial computer, referred to as the industrial computer. [0003] In order to ensure that the display and control system meets the requirements of functional safety, standards such as IEC61508 (corresponding to the national...
