Abstract

The invention relates to a dual-processor redundant data acquisition and control system with a self-detection function and belongs to the technical field of data acquisition and control in industrial process control. The objective of the invention is to solve the problems of low reliability and low security of an existing dual-core embedded system due to the incapability of the dual-core embedded system to judge the working states of peripheral circuit. According to the dual-processor redundant data acquisition and control system with the self-detection function, a main processor module and a slave processor module exchange data through a serial communication interface; the main processor module and the slave processor module exchange data with a data acquisition module through a bus isolation module; the data acquisition module realizes self-detection of the data acquisition circuits of the data acquisition module through a self-detection module; and the main processor module and the slave processor module transmits data or transmits acquired fault alarm information to an upper computer through a network interface module. The dual-processor redundant data acquisition and control system with the self-detection function of the invention can be adopted as an acquisition device of data in industrial process control.

Description
