Research on Software Architecture of the Design and Development of the Computer System on the Basis of Industrial Process Control

The industrial production of each link has widespread application of industrial process control in the computer system, the reliability and openness of the hardware equipment and hardware system should be ensured in the industrial process control computer system, implement rational software system architecture design should also be ensured, which plays a key role in the guarantee of the advancement and practicability of the system.

Implementation of Multi-Core Parallel Computation for Real-Time Turning of PID Parameters Based on Genetic Algorithm

The aim of the work described in this paper is to investigate the implementation of Multi-core Parallel Genetic Algorithm (McPGA) for real-time turning of PID parameters based on it using OpenMP. The performance of our scheme is discussed in comparison with that of the Sequential Genetic Algorithm (SGA) program running on the same computer. Numerical experimental results clearly show that McPGA is much better than SGA on convergence, premature and optimized speed. It can be used for PID parameter real-time turning in Industry Process Control Computer (IPC).

An Inexpensive Automation of a Powder Diffractometer

A conventional Bragg-Brentano type diffractometer was equipped with a stepping motor, a timer, and a scaler, and an MC68000 Motorola microprocessor which controls the diffractometer functions. The microprocessor was programmed to operate the diffractometer in a step-scanning mode, to check a datum and to communicate with a process control computer, e.g. a PDP 11/44 or a Micro VaxII computer.
